    Full Text Available St. John's Wort (Hypericum perforatum/ Cantarion has been well-studied which has been showed to have antidepressant, antiviral, and antibacterial effects. St Johns Wort gained popularity as an alternative treatment for mild to moderate depression. On the other hand, the neuropeptide, orphanin FQ/nociceptin (OFQ/N, is expressed in both neuronal and non-neuronal tissue. In the brain, OFQ/N has been investigated in relation to stress, anxiety, learning and memory, and addiction. The purpose opf this article is to review the current pharmacological, and clinical papers on St. John's wort, to provide information on orphanin FQ/nociceptin and finally to evaluate probable interaction between two.

    Stress, via corticosteroids release, influences bone mass density. Hypericum perforatum (Hp) a traditional remedy possess antidepressive activity (serotonin reuptake inhibitor) and wound healing properties. Hp preparation contains mainly hypericin, hyperforin, hyperoside and flavonoids exerting oestrogen-mimetic effect. Cold swimming represents an experimental model of stress associating mental strain and corporal exhaustion. This study investigates the Hp effect on femur and mandible bone mass changes in rats under cold forced swimming procedure. 30 male Wistar rats were randomized into three groups. Group A was treated with Methanolic extract of Hp (Jarsin®) via gastroesophageal catheter, and was submitted to cold swimming stress for 10 min/daily. Group B was submitted to cold stress, since group C served as control. Experiment duration was 10 days. Haematocrite and serum free fatty acids (FFA) were estimated. Furthermore volume and specific weight of each bone as well as bone mass density via dual energy X-Ray absorptiometry (DEXA) were measured. Statistic analysis by t-test. Hp treatment restores the stress injuries. Adrenals and bone mass density regain their normal values. Injuries occurring by forced swimming stress in the rats are significantly improved by Hp treatment. Estrogen-like effects of Hp flavonoids eventually may act favorable in bone remodeling.

    Hypericum perforatum Linn. (Hypericaceae) (St. John's wort) attenuates opium withdrawal signs. To explore the therapeutic potential of Hypericum perforatum in the management of opium-induced withdrawal syndrome. The effect of the Hypericum perforatum hydro-ethanol extract was investigated for potential to reverse naloxone (0.25 mg/kg)-induced opium withdrawal physical signs. Rats received opium extract (80-650 mg/kg) twice daily for 8 days along with Hypericum perforatum (20 mg/kg, orally) twice daily in chronic treatment and the same single dose 1 h before induction of withdrawal syndrome in the acute treated group. Hypericum perforatum reduced stereotype jumps and wet dog shake number in the chronic treatment compared to the saline control group (F(2, 24) = 3.968, p opium withdrawal syndrome possibly through direct or indirect interaction with opioid receptors. Further study is needed to clarify its mechanism.

    The hydromethanolic extract of Hypericum perforatum has been shown to be an effective antidepressant, although its mechanism of action is still unclear. In this study, in vivo microdialysis was used to investigate the effects of Hypericum perforatum-CO2 extract on dopamine (DA), 3,4-dihydroxyphenylacetic acid (DOPAC), serotonin (5-HT), and 5-hydroxyindoleacetic acid (5-HIAA) release in various areas of brain. Administration of Hypericum perforatum extract (1 mg/kg, p.o.) caused a slight, but significant increase of DA outflow both in the nucleus accumbens and the striatum. The maximal increase of DA efflux (+19.22+/-1.93%, relative to the control group) in the nucleus accumbens occurred 100 min after administration of Hypericum perforatum. In the striatum, the extract maximally enhanced DA outflow (+24.83+/-7.49 %, relative to the control group) 80 min after administration. Extraneuronal DOPAC levels were not significantly affected by Hypericum perforatum treatment. Moreover, Hypericum perforatum (1 mg/kg, p.o.) did not produce any significant effect on either 5-HT or 5-HIAA efflux in the ventral hippocampus. This study shows for the first time that Hypericum perforatum extract is capable of increasing in vivo DA release.

    Topical formulations such as oily extracts or ointments prepared with the flowering aerial parts of St. John's wort (Hypericum perforatum L., Hypericaceae) have been used in the management of a wide range dermatological problems including superficial wounds and burns, bruises, contusions and many others in the worldwide traditional medicines. This is the first case study reporting the beneficial effects of an oily extract of St. John's wort in the treatment of pressure sores in a intensive care unit (ICU) patient. The oily extract of St. John's wort was applied to a volunteer patient at ICU daily for forty successive days for wound care and treatment. Healing status was monitored macroscopically by measuring the wound size and stages at certain intervals as well as histopathological evaluation of the tissue sections taken at the initial and final dates of treatment. Evaluation of the results obtained from the macroscopical and histopathological experimentation have shown that oily extract of St. John's wort provided significant efficacy for the treatment of pressure sore wounds. St. John's wort oily extract may be suggested as a cost-effective option for the prevention or treatment of pressure sores in ICU patients. Copyright © 2016 Elsevier Ireland Ltd.

    Objective To assess whether early changes in HAM-D-17 anxiety/somatization items predict remission in two controlled studies of hypericum perforatum (St. John’s wort) versus an SSRI for major depressive disorder (MDD). Methods The Hypericum Depression Trial Study Group (NIMH) study randomized 340 subjects to hypericum, sertraline, or placebo for 8 weeks. The MGH study randomized 135 subjects to hypericum, fluoxetine, or placebo for 12 weeks. We examined whether remission was associated with early changes in anxiety/somatization symptoms. Results In the NIMH study, significant associations were observed between remission and early improvement in the anxiety-psychic item (sertraline arm), somatic-gastrointestinal item (hypericum arm), and somatic symptoms-general (placebo arm). None of the three treatment arms of the MGH study showed significant associations between anxiety/somatization symptoms and remission. When both study samples were pooled, we found associations for anxiety-psychic (SSRI arm), somatic-gastrointestinal and hypochondriasis (hypericum arm), and anxiety-psychic and somatic symptoms-general (placebo arm). In the entire sample, remission was associated with improvement in the anxiety-psychic, somatic-gastrointestinal, and somatic symptoms-general items. Conclusions The number and type of anxiety/somatization items associated with remission varied depending on the intervention. Early scrutiny of the HAM-D-17 anxiety/somatization items may help predict remission of MDD. PMID:21278577

    To assess whether early changes in Hamilton Depression Rating Scale-17 anxiety/somatization items predict remission in two controlled studies of Hypericum perforatum (St John's wort) versus selective serotonin reuptake inhibitors for major depressive disorder. The Hypericum Depression Trial Study Group (National Institute of Mental Health) randomized 340 patients to Hypericum, sertraline, or placebo for 8 weeks, whereas the Massachusetts General Hospital study randomized 135 patients to Hypericum, fluoxetine, or placebo for 12 weeks. The investigators examined whether remission was associated with early changes in anxiety/somatization symptoms. In the National Institute of Mental Health study, significant associations were observed between remission and early improvement in the anxiety (psychic) item (sertraline arm), somatic (gastrointestinal item; Hypericum arm), and somatic (general) symptoms (placebo arm). None of the three treatment arms of the Massachusetts General Hospital study showed significant associations between anxiety/somatization symptoms and remission. When both study samples were pooled, we found associations for anxiety (psychic; selective serotonin reuptake inhibitors arm), somatic (gastrointestinal), and hypochondriasis (Hypericum arm), and anxiety (psychic) and somatic (general) symptoms (placebo arm). In the entire sample, remission was associated with the improvement in the anxiety (psychic), somatic (gastrointestinal), and somatic (general) items. The number and the type of anxiety/somatization items associated with remission varied depending on the intervention. Early scrutiny of the Hamilton Depression Rating Scale-17 anxiety/somatization items may help to predict remission of major depressive disorder.

    Context: In irritable bowel syndrome (IBS), disturbance of bowel motility is associated with infiltration of inflammatory mediators and cytokines into the intestine, such as neutrophils, myeloperoxidase (MPO), tumor necrosis factor alfa (TNF-α), and lipid peroxide. Aims: Regarding promising anti-inflammatory and anti-oxidative effects of Hypericum perforatum (HP) extract, besides its anti-depressant effect, this study was designed to evaluate the effects of HP in an experimental model of IBS. Settings and Design: IBS was induced by a 5-day restraint stress in rats. The HP extract was administered by gavage in doses of 150, 300, and 450 mg/kg for 26 days. Fluoxetine and loperamide were used as positive controls. Gastric emptying and small bowel and colon transit, besides the levels of TNF-α, MPO, lipid peroxidation, and antioxidant power, were determined in colon homogenates. Statistical Analysis Used: Data were analyzed by one-way ANOVA followed by Tukey's post hoc test for multiple comparisons. Results: A significant reduction in small bowel and colonic transit (450 mg/kg), TNF-α, MPO, and lipid peroxidation and an increase in antioxidant power in all HP-treated groups (150, 300, and 450 mg/kg) were seen as compared with the control group. Gastric emptying did not alter significantly when compared with the control group. Treatment with loperamide (10 mg/kg) significantly inhibited gastric emptying and small bowel and colonic transit, while flouxetine (10 mg/kg) decreased gastric emptying, TNF-α, MPO, and lipid peroxidation and increased the antioxidant power of the samples in comparison with the control group. Conclusions: HP diminished the recruitment of inflammatory cells and TNF-α following restraint stress not in a dose-dependent manner, possibly via inhibition of MPO activity and increasing colon antioxidant power, without any difference with fluoxetine. The HP extract inhibits small bowel and colonic transit acceleration like loperamide but has minimal

    Hypericum perforatum (St John's Wort [SJW]) counts among the most favourite herbal drugs, and is the only herbal alternative to classic synthetic antidepressants in the therapy of mild to moderate depression. Several clinical studies have been conducted to verify the effectiveness of ethanolic or methanolic extracts of SJW. Alcoholic SJW extracts are a mixture of substances with widely varying physical and chemical properties and activities. Hyperforin, a phloroglucinol derivative, is the main source of pharmacological effects caused by the consumption of alcoholic extracts of SJW in the therapy of depression. However, several studies indicate that flavone derivatives, e.g. rutin, and also the naphthodianthrones hypericin and pseudohypericin, take part in the antidepressant efficacy. In contrast to the amount of documentation concerning clinical efficacy, oral bioavailability and pharmacokinetic data about the active components are rather scarce. The hyperforin plasma concentration in humans was investigated in a small number of studies. The results of these studies indicate a relevant plasma concentration, comparable with that used in in vitro tests. Furthermore, hyperforin is the only ingredient of H. perforatum that could be determined in the brain of rodents after oral administration of alcoholic extracts. The plasma concentrations of the hypericins were, compared with hyperforin, only one-tenth and, until now, the hypericins could not be found in the brain after oral administration of alcoholic H. perforatum extracts or pure hypericin. Until now, the pharmacokinetic profile of the flavonoids in humans after oral administration of an alcoholic H. perforatum extract has been investigated in only one study. More data are available for rutin and the aglycone quercetin after administration of pure substances or other flavonoid sources.

    Surgical wounds in diabetic patients still remain a problem till the present day. As a common plant found around the world, Hypericum perforatum L. (Hypericaceae) is traditionally prepared as an oily extract and used as a folk remedy for various diseases such as wounds, burns, cuts, etc. This study aims to evaluate the effect of St. John's wort (Hypericum perforatum) on problematic wounds while comparing oral and topical applications. Incisional and excisional wound models were made on the dorsal regions of 54 diabetic Spraque-Dawley rats. The rats were divided into the following six groups (n = 9): Group 1: control, Group 2: diabetic, Group 3: diabetic oral Hypericum perforatum, Group 4: diabetic topical Hypericum perforatum, Group 5: diabetic oral olive oil, and Group 6: diabetic topical olive oil. Groups 3 and 4 had significantly higher tensile strength, tissue hydroxyproline concentration, and collagen density compared with Group 2. Inflammatory cell density and collagen density on day 3 were significantly higher in Groups 3 and 6 compared with Group 2. On day 21, Groups 3 and 6 had significantly higher fibroblastic activity compared with Group 2. This study has proved that oral St. John's wort has more positive effects on problematic wounds compared with topical St. John's wort and olive oil, which is a vehicle. Hypericum perforatum results with faster inflammatory response and better healing. These results could be an addition to literature about the clinical usage of Hypericum perforatum on diabetic wounds.

    The popularity of St. John's wort (Hypericum perforatum) for the treatment of depression is increasing and, in recent years, concerns about its use during pregnancy and breastfeeding have emerged. The purpose of this study was to investigate, in Wistar rats, the effects of a treatment with hypericum administered prenatally and during breastfeeding (from 2 weeks before mating to 21 days after delivery). Two doses of the extract were chosen, 100 mg/kg per day, which, based on surface area, is comparable to the dose administered to humans, and 1000 mg/kg per day. A microscopical analysis of livers, kidneys, hearts, lungs, brains, and small bowels was performed. A severe damage was observed in the livers and kidneys of animals euthanized postnatally on days 0 and 21. The lesions were more severe with the higher dose and in animals that were breastfed for 21 days; however, an important renal and hepatic damage was evident also with the dose of 100 mg/kg per day. In addition, similar serious hepatic and renal lesions were evident also in animals that were exposed to hypericum only during breastfeeding. In particular, a focal hepatic damage, with vacuolization, lobular fibrosis, and disorganization of hepatic arrays was evident; in the kidney, a reduction in glomerular size, disappearance of Bowman's space, and hyaline tubular degeneration were found. The results obtained in this study indicate that further, appropriate histological studies should be performed in other animal species to better evaluate the safety of hypericum extracts taken during pregnancy and breastfeeding

  17. Rats treated with Hypericum perforatum during pregnancy generate offspring with behavioral changes in adulthood

    Leandro V. Campos

    Full Text Available Abstract Drugs used in the treatment of depression can cross the placenta giving rise to questions regarding the effects these drugs exert on the fetus. Hypericum perforatum L., Hypericaceae, is a natural product used to treat depression. However, information about its toxicity and the occurrence of alterations in the central nervous system development of the offspring is scarce. This work assessed the behavior of adult male rats born from mothers treated with Hypericum extract during gestation and analyzed the fluorescence of the extract in different organs of mothers and fetuses. Male pups were divided into three treated groups, corresponding to the administration of the Hypericum extract to mothers at the dose levels of 36 mg/kg, 72 mg/kg and 144 mg/kg, and one control group in which the mothers received distilled water. At 90 days of age, the offspring underwent the following tests: rotarod, pentobarbital-induced sleep time, elevated plus maze, hole-board and forced swimming test. The observed fluorescence indicated the presence of the extract in all tissues analyzed. The obtained results suggest lasting changes in the performances displayed in the CNS, depression and anxiety tests, indicating that the use of Hypericum during gestation could interfere with the behavioral development of the offspring reducing anxiety and depression when they become adults. We suggest that these alterations are associated with the reprogramming of the brain regions related to changes in emotional reactivity.

    Highlights: • Impact of La, Cd and Cd + La on the metabolism of Hypericum perforatum was compared. • La stimulated ROS and suppressed growth and basic antioxidants more than Cd. • Impact of Cd + La was not synergistic including the sod gene expression. • La depleted hypericin and hyp-1 gene expression but amount of hyperforin increased. • La reduced flavonols and procyanidins mainly in the roots and affected anatomy - Abstract: Physiology, oxidative stress and production of metabolites in Hypericum perforatum exposed to moderate Cd and/or La concentration (10 μM) were studied. La evoked increase in reactive oxygen species, malondialdehyde and proline but suppressed growth, tissue water content, glutathione, ascorbic acid and affected mineral nutrient contents more than Cd while the impact of Cd + La was not synergistic. Similar trend was observed at the level of superoxide dismutase gene expression. Shoot Cd amount increased in Cd + La while only root La increased in the same treatment. Extensive quantification of secondary metabolites revealed that La affected phenolic acids more pronouncedly than Cd in shoots and roots. Flavonols were suppressed by La that could contribute to the appearance of oxidative damage. Procyanidins increased in response to La in the shoots but decreased in the roots. Metabolic responses in Cd + La treatment resembled those of La treatment (almost identically in the roots). Phenylalanine ammonia-lyase activity was mainly suppressed by La. The presence of La also depleted amount of hypericin and expression of its putative gene (hyp-1) showed similar trend but accumulation of hyperforin increased under Cd or La excess. Clear differences in the stem and root anatomy in response to Cd or La were also found. Overall, H. perforatum is La-sensitive species and rather Cd ameliorated negative impact of La.

    To evaluate the effectiveness of a phytotherapeutic intervention comprising a combination of Hypericum perforatum (St. John's wort) and Vitex agnus-castus (Chaste tree/berry) in the management of menopausal symptoms. A double-blind, randomized, placebo-controlled, parallel trial was performed over 16 weeks in 100 eligible late-perimenopausal or postmenopausal women experiencing hot flushes and other menopausal symptoms. Herbal combination therapy or placebo tablets were administered twice daily. The primary endpoint was hot flush episodes. Secondary endpoints included Greene Climacteric Scale scores, Hamilton Depression Inventory scores, and Utian Quality of Life Scale scores. Ninety-three women completed the study. Data analysis on an intent-to-treat basis found no significant differences between the two groups for any of the endpoints. Analyses performed at interim data time points revealed no significant differences at week 4, 8, or 12 for daily weighted flushes or scores on the Greene Climacteric Scale or Hamilton Depression Inventory. However, significant improvements across the treatment phase were observed in both the placebo and active treatment groups for these endpoints. No significant change was found for either group on quality of life. The herbal combination of H. perforatum and V. agnus-castus was not found to be superior to placebo for the treatment of menopausal symptoms. The herbal combination was well tolerated with no significant adverse events noted in the short term. Robust findings from quality studies such as this are important for informing the community, healthcare providers, and regulatory authorities.

    Full Text Available Background & Objective: Anti-inflammatory effect of Hypericum have long been considered. Ulcerative Colitis (UC is a form of Inflammatory Bowel Disease (IBD. In this study, the effects of Hypericum perforatum on histopathological changes and tissue malondialdehyde (MDA level of colonic tissue in rats with induced UC were evaluated. Materials & Methods: 70 rats were divided into seven equal groups. Colitis was induced by acetic acid.. Groups I and II received 1 mL of 600 and 300 mg/kg H. perforatum extract orally per day respectively; groups III and IV received 1 mL of 20% and 10% intra-colonic gel form of H. perforatum extract daily respectively; group V, as positive control, received 1 mL of intra-colonic Asacol; group VI received 1 mL of normal saline as negative control; group VII received just intra-colonic gel base. All the animals were evaluated for histological changes and tissue MDA level of colon seven days after the treatment. Results: H. perforatum extract in the two forms of trans-rectal and oral administration could result in a more healing effect on acetic acid-induced damaged colonic tissue with a reduction in the MDA activity. In trans-rectal administration, the 20% gel had a better healing response than the 10% gel. In oral administration, the 600 mg/kg dosage had a better healing response than the 300 mg/kg. Conclusions: Therefor, H. perforatum can be considered as a treatment of choice for UC especially in trans-rectal gel form.

    The beneficial effects of antioxidants in plants are mainly extrapolated from in vitro studies or short-term dietary supplementation studies. Due to cost and duration, relatively little is known about whether dietary antioxidants are beneficial in whole animals' life span or not. To address this question, under heat stress (35°C), Hypericum perforatum was extracted with petroleum ether and the nematodes Caenorhabditis elegans exposed to three different extract concentrations (1mg/mL, 0.1mg/mL, 0.01mg/mL) of H. perforatum. We report that Hypericum perforatum extracts did not increase life span and slow aging related increase in C. elegans. Moreover, one fraction (1mg/mL) increased declines of C. elegans life span and thermotolerance. Given this mounting evidence for life span role of H. perforatum in the presence of heat stress in vivo, the question whether H. perforatum acts as a prooxidant or an antioxidant in vivo under heat stress arises.

    Full Text Available Parkinson's disease (PD is an age-related neurodegenerative disorder characterized by the slow and progressive death of dopaminergic neurons in the (substantia nigra pars compact. Hypericum perforatum (H. perforatum is a plant widely used as an antidepressant, that also presents antioxidant and anti-inflammatory properties. We evaluated the effects of H. perforatum on the turning behavior of rats submitted to a unilateral administration of 6-hydroxydopamine (6-OHDA into the medial forebrain bundle as an animal model of PD. The animals were treated with H. perforatum (100, 200, or 400 mg/kg, v.o. for 35 consecutive days (from the 28th day before surgery to the 7th day after. The turning behavior was evaluated at 7, 14 and 21 days after the surgery, and the turnings were counted as contralateral or ipsilateral to the lesion side. All tested doses significantly reduced the number of contralateral turns in all days of evaluation, suggesting a neuroprotective effect. However, they were not able to prevent the 6-OHDA-induced decrease of tyrosine hydroxylase expression in the lesioned striatum. We propose that H. perforatum may counteract the overexpression of dopamine receptors on the lesioned striatum as a possible mechanism for this effect. The present findings provide new evidence that H. perforatum may represent a promising therapeutic tool for PD.

    The efficacy and tolerability of current treatments for smoking cessation are relatively poor. More research is required to address the biological mechanisms underpinning nicotine withdrawal and drug treatments for smoking cessation. We assessed the neurocognitive effects of Remotiv® (Hypericum perforatum Special Extract - Ze 117), Nicabate CQ Nicotine Replacement therapy (NRT) and combined NRT/HP during conditions of smoking abstinence in 20 regular smokers aged between 18 and 60 years over a period of 10 weeks during smoking cessation. A Spatial Working Memory (SWM) task was completed at baseline, 4 weeks prior to quitting, as well as at the completion of the study, following the 10 weeks of treatment. Brain activity was recorded during the completion of the SWM task using Steady-State Probe Topography. Reaction time and accuracy on the SWM task were not found to be significantly different between treatment groups at retest. Differences in SSVEP treatment profiles at retest are discussed, including stronger SSVEP Amplitude increase in posterior-parietal regions for the HP and NRT groups and greater fronto-central SSVEP Phase Advance in the HP group.

    Considered an antidepressant and anti-anxiety agent, Hypericum perforatum affects multiple neurotransmitters in a non-competitive synergistic manner, and may have nootropic potential. We quantitatively reviewed the pre-clinical literature to examine if there is a cognitive-enhancing effect of H. perforatum in healthy rodents. Additionally, within these studies, we compared the effects observed in intact rodents versus those whose performance has been impaired, mostly through stress manipulations. The meta-analysis incorporated studies that examined the effect of H. perforatum versus placebo on memory indices of task performance. All analyses were based on weighting different studies according to their inverse variance. Thirteen independent studies (published 2000–2014) involving 20 experimental comparisons met our inclusion criteria. The results showed a large positive effect of H. perforatum on cognitive performance for intact, healthy rodents (d = 1.11), though a larger effect emerged for stress-impaired rodents (d = 3.10 for restraint stress). The positive effect on intact rodents was observed in tasks assessing reference memory as well as working memory, and was not moderated by the type of memory or motivation (appetitive versus aversive). Thus, while primarily considered as a medication for depression, H. perforatum shows considerable nootropic potential in rodents. PMID:27762349

    Recent studies in wound dressing applications offer new therapies and promote wound healing process. The aim of this study was to develop Hypericum perforatum (St John's Wort) oil incorporated chitosan films for wound dressing applications. H. perforatum oil as a potential therapeutic agent was encapsulated in chitosan film to achieve a better wound dressing material. Oil incorporated chitosan films were successfully prepared by solvent casting method in different oil concentrations (0.25-1.5%v/v). Water vapor permeability (WVP), mechanical test, swelling behavior and surface hydrophobicity were performed in order to characterize the prepared films. Antimicrobial test was performed by disc diffusion method and the growth inhibition effects of the films including different amount of H. perforatum oil were investigated on Escherichia coli and Staphylococcus aureus. WVP increased with oil incorporation and the highest value was obtained for 0.25% oil concentration.The highest strain value was obtained in 0.25% oil content films although tensile stress decreased with increasing oil content. H. perforatum oil incorporated films had antimicrobial effect on both microorganisms. Chitosan based films had no cytotoxic effects on NIH3T3fibroblast cells and provided a good surface for cell attachment and proliferation. The results showed that the H. perforatum incorporated chitosan films seems to be a potential and novel biomaterial for wound healing applications. Copyright © 2017 Elsevier B.V.

    Hypericum perforatum (HP) belongs to the Hypericaceae family and is one of the oldest used and most extensively investigated medicinal herbs. The medicinal form comprises the leaves and flowering tops of which the primary ingredients of interest are naphthodianthrones, xanthones, flavonoids, phloroglucinols (e.g. hyperforin), and hypericin. Although several constituents elicit pharmacological effects that are consistent with HP's antidepressant activity, no single mechanism of action underlying these effects has thus far been found. Various clinical trials have shown that HP has a comparable antidepressant efficacy as some currently used antidepressant drugs in the treatment of mild/moderate depression. Interestingly, low-hyperforin-content preparations are effective in the treatment of depression. Moreover, HP is also used to treat certain forms of anxiety. However, HP can induce various cytochrome P450s isozymes and/or P-glycoprotein, of which many drugs are substrates and which are the main origin of HP-drug interactions. Here, we analyse the existing evidence describing the clinical consequence of HP-drug interactions. Although some of the reported interactions are based on findings from in vitro studies, the clinical importance of which remain to be demonstrated, others are based on case reports where causality can, in some cases, be determined to reveal clinically significant interactions that suggest caution, consideration, and disclosure of potential interactions prior to informed use of HP.

    With regard to an increase in the life expectancy for women and the consistency of the menopause age, a significant portion of women's age is passed after the menopause. Menopause is considered as a critical and sensitive period due to the changes and the disorders that are involved in it. Vasomotor symptoms, sleep disorders and psycho-mental changes are among the most prevalent symptoms of this period. Hormone therapy is a common treatment and it involves some problems for most individuals. The purpose of this study was to comparatively examine the effects of two herbal medications, Hypericum Perforatum and Passion Flower, on menopause symptoms. This study was of a clinical-experimental type which was done in 1388 in Isfahan. The sample included 59 menopausal women who had the conditions for entering into the study. The individuals were selected via simple sampling and were assigned randomly into two groups of Hypericum Perforatum treatment group (30 women) and Passion Flower group (29 women). The required data were filled out through interview, Personal Characteristics Questionnaire, and Cooperman's Index for menopause symptoms in three stages of pre-intervention, the third week of intervention, and the sixth week of intervention. The results were analyzed by descriptive and inferential statistical methods and the statistical software of SPSS. The findings showed that the average score of menopause symptoms in two treatment groups of Hypericum Perforatum and Passion Flower had a significant decrease throughout the third and the sixth weeks of study (p 0.05). With regard to the effects of Hypericum Perforatum and Passion Flower on treating menopause precocious symptoms (vasomotor signs, insomnia, depression, anger, headache, etc.), these two herbs can be used as an alternative treatment for individuals who cannot, whatsoever, use hormone therapy.

    Hypericum perforatum is a perennial medicinal plant known as "St. John's wort" in Western Europe and has been used in the treatment of several diseases for centuries. In the present study, morphologic, phenologic and population variability in pseudohypericin and hyperforin concentrations among H. perforatum populations from Northern Turkey was investigated for the first time. The aerial parts of H. perforatum plants representing a total of 30 individuals were collected at full flowering from 10 sites of Northern Turkey to search the regional variation in the secondary metabolits concentrations. For morphologic and phenologic sampling, plants from one site were gathered in five phenological stages: vegetative,floral budding, full flowering, fresh fruiting and mature fruiting. The plant materials were air-dried at room temperature and subsequently assayed for chemical concentrations by high performance liquid chromatography. Secondary metabolite concentrations ranged from traces to 2.94mg/g dry weight (DW) for pseudohypedcin and traces -6.29mg/g DW for hyperforin. The differences in the secondary metabolite concentrations among populations of H. perforatum were found to be significant. The populations varied greatly in hyperforin concentrations, whereas they produced a similar amount of pseudohypericin. Concentrations of both secondary metabolites in all tissues increased with advancing of plant development and higher accumulation levels were reached at flowering. Among different tissues, full opened flowers were found to be superior to stems, leaves and the other reproductive parts with regard to pseudohypericin and hyperforin accumulations. The present findings might be useful to optimize the processing methodology of wild-harvested plant material and obtain Increased concentrations of these secondary metabolites.

    Full Text Available Introduction: Medicinal and aromatic plants can play an important role in commercial crops, which also represent a safe alternative for chemical pharmaceutical industries. St. John’s Wort (Hypericum perforatum L. due to its therapeutic efficacy has been used for decades in folk medicine and is considered as a promising medicinal plant with valuable potential as a source of hypericin, essential oils and antioxidants. Studies on agronomic factors such as application of potassium and humic acid as well as nitrogen fertilization on yield, essential oil and antioxidant activity of Hypericum perforatum have not been investigated thoroughly until now. This study was designed to study the effect of using humic acid and potassium sulphate on morphological and phytochemical characteristics of Hypericum perforatum. Materials and Methods: The plant material was prepared from Science and Technology Park in Khorasan-e Razzavi–Mashhad. In spring, the plants were transplanted into the field of Horticulture department, Ferdowsi University of Mashhad, for fertilizing treatments. The experimental layout was factorial in a complete randomized design (CRD, with three replications. Potassium Sulphate (K2SO4 was applied at the rates of 0.0 (K0, 60 (K60 and 100 (K100 kg ha-1. The other treatment were humic acid, which was applied at three rates 0 (H0, 20 (H20 and 40 (H40 L ha-1. Plants were treated at two stages, before flowering by potassium fertilizer and fertigated four times in 15-day intervals with humic acid. Besides the fresh and dry weight, number of flowers, stem height and number of flowering stems were determined at the end of the growing stage. Results and Discussion: The ANOVA indicated that most of measured attributes of Hypericum perforatum plant were significantly affected by both treatments. Data presented revealed that the highest stem (91.6 cm was recorded at the highest level of potassium sulphate (K100 treatment, while the shortest height (60

    Full Text Available Background/Aim. The beneficial effects of medicinal plants are well-known from the ancient times. However, expansion of phytopharmacy and phytotherapy occured during the last decades. Medicinal plants can absorb environmental contaminants from the ground and consequently may cause harmful effects on human health. Quality control usually comprises standard methodology which includes macroscopic identification and examination of active ingredients. Additionaly, there is a permanent need to control the level of pollutants in herbs, with a particular attention to the level of toxic metals. In this study we estimated the level of contamination by determining the content of cadmium (Cd in the herbs of Hypericum perforatum and Thymus serpyllum collected from the different localities of the mountains Rtanj and Ozren. Methods. Herbs of investigated plants were collected during July 2005 from various localities of Rtanj and Ozren mountains. After drying, homogenization and mineralization, Cd content was determined by atomic absorption spectrophotometry. Results. The obtained results show that Cd content varies significantly in Hypericum perforatum samples collected. The lowest Cd level was found in samples from the one of Rtanj localities (0.25 mg Cd/kg, while the highest was observed in Hypericum perforatum from Ozren locality (1.24 mg/kg. Levels of Cd in the three of four investigated localities were higher than pro posed by WHO (0.3 mg/kg dried herb material. In all investigated samples of Thymus serpyllum herbs Cd levels were below the limit of detection of analytical method (0.2 mg Cd/kg dried materials. Conclusion. This work contributes to the issue of Cd content in Hypericum perforatum and Thymus serpyllum grown in localities of Rtanj and Ozren, and implies the importance for systemic control of Cd content in Hypericum species in order to provide safety of their preparations. Furthermore, regarding Cd toxicity, maximal permissible level of Cd in

    Changes in phenolic metabolism after elicitation with Colletotrichum gloeosporioides (CG) has been studied in Hypericum perforatum L. (HP) cell suspension cultures. Soluble phenolics were analysed by HPLC-DAD and HPLC-DAD-MS/MS. HP cultures elicited with the CG elicitor showed a significant increase in xanthone accumulation. Xanthone accumulation increased twelve fold when the cells were primed with methyl-jasmonate (MeJ) or salicylic acid (SA), before elicitation. HP cultures exposed only to MeJ produced a set of flavonoids, the flavones which represent a substantial part (approx. 40%) of the total flavonoids accumulated in these cells. The possible importance of xanthones as a component of defence mechanism of HP against biotic stress is discussed.

    St John's wort products (Hypericum perforatum L.) are widely available for sale in many countries including the UK via the internet. In the UK, these products are required to hold either a marketing authorisation or Traditional herbal registration (THR) to be sold legally. The THR and other regulatory schemes help to ensure product safety and quality providing an example of best practice but there is a risk if both regulated and un-regulated products continue to be available to consumers. The project is embedded in a larger study aiming to investigate the quality of different herbal medicinal products along diverse value chains. Here we focus on a comparison of the quality of the finished products and assess phytochemical variation between registered products (THRs) and products obtained from the market without any registration. 47 commercial products (granulated powders and extracts) were sourced from different suppliers. We analysed these samples using high performance thin layer chromatography (HPTLC) and 1 H NMR spectroscopy coupled with multi-variate analysis software following a method previously developed by our group. The consistency of the products varies significantly. Adulteration of the products (36%), possibly with other Hypericum species obtained from China or use of chemically distinct H. perforatum cultivars or chemotypes, and adulteration of the products (19%) with food dyes (tartrazine, amaranth, brilliant blue, sunset yellow) were the principle findings of this study. There is significant compositional variation among commercial finished products and two main causative quality problems were identified as adulteration by incorrect species or adulteration with food dyes. Generally, food supplements and unlicensed products were found to be of poorer quality than the regulated ones including THRs. Copyright © 2017 Elsevier GmbH. All rights reserved.

    Full Text Available St. John's Wort (Hypericum perforatum L. is one of the most studied plant species in the family Hypericaceae. The aim of this study was the identification of the constituents of methanol extract of H. perforatum and optimization of conditions for their isolation. The main components of the methanol extract were isolated on preparative ZORBAX Eclipse XDB C18 column with solvent system consisting of methanol and 1x10-2 M ammonium acetate in water. Constituents of the extract were identified by comparing their retention times with the retention times of the standards, with the literature data and the UV spectra. By varying the conditions of chromatography, the optimal conditions for isolation of the methanol extract constituents were determined: mobile phase consisting of methanol and 1x10-2 M ammonium acetate in water in ratio 1 : 1, sample concentration 100 mg/mL, sample volume 30 µL, flow 2 mL/min. Under these conditions 7 components of the methanol extract were isolated.

    Introduction and background: We have reported on the polar methanolic fraction (PMF) of Hypericum Perforatum L as a novel photosensitizing agent for photodynamic therapy (PDT) and photodynamic diagnosis (PDD). PMF has been tested in human leukemic cells, HL-60 cells, cord blood hemopoietic progenitor cells, bladder cancers derived from metastatic lymph node (T-24) and primary papillary bladder lesion (RT-4). However, the mechanisms of the effects of PMF on these human cell lines have not been elucidated. We have investigated mechanisms of PMF + light versus PMF-alone (dark experiment) in T-24 human bladder cancer cells. Methods: PMF was prepared from an aerial herb of HPL which was brewed in methanol and extracted with ether and methanol. Stock solutions of PMF were made in DSMO and stored in dark conditions. PMF contains 0.57% hypericin and 2.52% hyperforin. The T24 cell line was obtained from American Type Culture Collection (ATCC). In PDT treatment, PMF (60μg/ml) was incubated with cells, which were excited with laser light (630nm) 24 hours later. Apoptosis was determined by DNA fragmentation/laddering assay. DNA isolation was performed according to the manufacture's instructions with the Kit (Oncogene Kit#AM41). Isolated DNA samples were separated by electrophoresis in 1.5% in agarose gels and bands were visualized by ethidium bromide labeling. The initial cell cycle analysis and phase distribution was by flow cytometry. DNA synthesis was measured by [3H] thymidine incorporation, and cell cycle regulatory proteins were assayed by Western immunoblot. Results: The results of the flow cytometry showed PMF +light induced significant (40%) apoptosis in T24 cells, whereas Light or PMF alone produced little apoptosis. The percentage of cells in G 0/G I phase was decreased by 25% and in G2/M phase by 38%. The main impact was observed on the S phase which was blocked by 78% from the specific photocytotoxic process. DNA laddering analysis showed that PMF (60

    Full Text Available To study the effects of nitrogen and zinc fertilizer on the morphological traits and essential oil yield of St. John’s wort (Hypericum perforatum a greenhouse experiment in a factorial randomized complete block design with three replications was conducted at University of Tabriz, Iran in 2012. Treatments consisted of three levels of zinc sulphate with a concentration of zinc fertilizer (zero, 3 and 6 parts per thousand and four levels of nitrogen fertilizer (zero, 50, 100, 150 kg/ha. One half of the fertilizers were applied 20 days after planting of plants and the rest 40 days after transplanting. Traits evaluated were plant height, inflorescence number, leaf area, plant fresh and dry weights and plant essential oil content. The results showed that the traits under study were affected by rate of fertilizer applications. Highest plant height, number of inflorescences, leaf area and essential oil yield were obtained by using 150 kg/ha of nitrogen and applying zinc with 0.006 concentration. Highest fresh and dry weights of above ground parts were also produced by using 150 kg/ha of nitrogen fertilizer along with zinc fertilizer 0.003.

    The present study was conducted to determine phenologic and morphogenetic variation of hypericin, chlorogenic acid and flavonoids, as rutin, hyperoside, apigenin-7-O-glucoside, quercltrin, quercetin content of Hypericum perforatum L. growing in Turkey. Wild growing plants were harvested at vegetative, floral budding, full flowering,fresh fruiting and mature fruiting stages and dissected into stem, leaf and reproductive tissues and assayed for bioactive compounds by the High performance liquid chromatography (HPLC) method. Hyperlcin concentration ranged between 0 and 2.73 mg/g DW, chlorogenic acid 0.00-3.64 mg/g DW, rutin 0.00-3.36 mg/g DW, hyperoside 0.04-22.42 mg/g DW, quercitrin 0.03-3.45 mg/g DW and quercetin 0.04-1.02 mg/g DW depending on ontogenetic and morphogenetic sampling. Leaves were found to be superior to stems and reproductive parts with regard to phenolic accumulation for all compounds tested while flowers accumulated the highest levels of hypericin. Quercitrin,quercetin and hypericin content in all tissues increased with advancing of developmental stages and reached their highest level during flower ontogenesis. Similarly, chlorogenic acid, hyperoside and apigenin-7-O-glucoside content in different plant parts increased during plant development, however, the highest level was observed at different stages of plant phenology for each tissue. Chlorogenic acid was not detected in stems, leaves and reproductive parts in several stages of plant phenology and its variation during plant growth showed inconsistent manner. In contrast to the other compounds examined, rutin content of stems and leaves decreased with advancing of plant development and the highest level for both tissues was observed at the vegetative stage. However,content of the same compound in reproductive parts was the highest at mature fruiting. The present findings might be useful to obtain increased concentration of these natural compounds.

    To review which names are used to refer to Hypericum perforatum L. in health regulation and medicinal plant references, and the potential for ambiguity or imprecision. Structured searches of Kew's Medicinal Plant Names Services Resource, supplemented with other online bibliographic resources, found that the scientific name Hypericum perforatum L. is used consistently in the literature, but variation between subspecies is rarely considered by researchers. Research is still published using only the common name 'St John's wort' despite it being imprecise; at least 80 other common names are also used for this plant in multiple languages. Ambiguous and alternative plant names can lead to ineffective regulation, misinterpretation of literature, substitution of raw material or the failure to locate all published research. Kew's Medicinal Plant Names Services (MPNS) maps all names used for each plant in medicinal plant references onto current taxonomy, thereby providing for disambiguation and comprehensive access to the regulations and references that cite that plant, regardless of the name used. MPNS also supplies the controlled vocabulary for plant names now required for compliance with a new standard (Identification of Medicinal Products, IDMP) adopted by medicines regulators worldwide. © 2017 Royal Pharmaceutical Society.

Thus, a research was conducted in a factorial experiment (3×3 based on completely randomized design with three replications. Treatments consisted of potassium sulphate (Kx at three concentrations (0, 60 and 100 Kg/h which were treated before flowering and humic acid (Hx at three concentrations (0, 20 and 40 L/h which were fertigated four times of 15-days intervals. Results showed that the plant stem height, number of flowering stems and number of flowers were significantly affected by simple effect of each fertilizers (p<0.01, while their interaction effect was not significant for the plants height. The highest contents of fresh and dry weight were achieved under the highest amounts of fertilizers (K100 and H40. The highest stem height, number of flowers and number of flowering stems also belonged to these treatments. Increment of applied fertilizers led to increase of obtained essential oils, so that application of these fertilizers simultaneously increased the essential oil content up to 6-fold. Regarding the antioxidant activity, applied fertilizers at their high levels showed significant effects on decrease of EC50, which means the increment of antioxidant activity of H. perforatum.

    Objective: In this study, we aimed at evaluation of the efficacy of Hypericum perforatum and flaxseed on hot flash, vaginal atrophy and estrogen-dependent cancers in menopausal women Materials and Methods: We searched MEDLINE, Scopus, and the Cochrane Central Register of Controlled Trials (RCT) to explore trials that assessed the effectiveness of H. perforatum and flaxseed on hot flash, vaginal atrophy and estrogen-dependent cancers. In this regard, the following terms were used “menopause AND H. perforatum OR flaxseed OR Linum usitatissimum. Only randomized controlled trials were included in the study. Results: Nine RCTs were included in this systematic review. Based on the literature, flaxseed showed beneficial effect on hot flash frequency and intensity, which was not statistically significant. According to two trials, flaxseed showed estrogenic effects; however, no conclusion regarding cancer promoting or protecting effects can be made. The evidence of the efficacy of the flaxseed on alleviating vaginal atrophy was also limited due to inconsistent findings in this regard. One trial declared that Vitex agnus-castus and H. perforatum showed comparable decrease in the frequency of hot flashes. Conclusion: The results of our systematic review suggest beneficial effect on vasomotor symptom with both of flaxseed and H. perforatum. Consistent conclusion regarding estrogen-dependent cancers and maturation value is limited due to small number of trials related to flaxseed. Further trials are still needed to confirm the results of our systematic review. PMID:27462550

The results of our systematic review suggest beneficial effect on vasomotor symptom with both of flaxseed and H. perforatum. Consistent conclusion regarding estrogen-dependent cancers and maturation value is limited due to small number of trials related to flaxseed. Further trials are still needed to confirm the results of our systematic review.

    Purpose: To evaluate the effect of a hypericum extract (Hypericum perforatum) on the labeling of blood elements with technetium- 99m ( 99m Tc) and in the bioavailability of the radiopharmaceutical sodium pertechnetate in Wistar rats. Methods: Blood (heparinized) withdrawn from Wistar rats is incubated with a hypericum extract, with a stannous chloride and with 99m Tc, as sodium pertechnetate ( 99m TcO Na). Plasma (P) and cells (C) are isolated by centrifugation. Samples of P and C are also precipitated with trichloroacetic acid (TCA 5%) and soluble (FS-P; FS-C) and insoluble (FI-P; FI-C) fractions are separated. In the bioavailability analysis, the extract or NaCl 0.9% solution is administrated into Wistar rats (gavage) during 15 days. Sodium pertechnetate was administered and after 10 min, the animals are sacrificed, the organs were isolated, the radioactivity determined in a well counter, and the percentages of radioactivity per gram (%ATI/g) in the organs are calculated. Results: The hypericum extract decreased significantly (P 99m Tc on the erythrocytes and plasma and cellular proteins. Moreover, it could produce metabolic alterations with influence in the uptake of the radiopharmaceutical 99m TcO 4 Na in bone, muscle, pancreas and thyroid. (author)

    Full Text Available We have selectively separated cis- and/or vicinal-diol-containing flavonoids from Hypericum perfaratum (HP by adsorption/desorption using aminophenylboronic acid (APBA functionalized uniform (1.6 μm silica microparticles (BASPs synthesized via the Stöber method. Silica particles were alkylated by its terminal –OH with 3-aminopropyl trimethoxysilane (APTS, glutaraldehyde (GA and APBA. The results from model adsorption studies indicated that these microparticles selectively adsorbed quercetin and rutin but partially apigenin. The antioxidant and antiradical activities of the desorption solution were slightly higher than that of the post-adsorption solution. These results indicated that the BASP selectively adsorbed the cis- and/or vicinal antioxidant and antiradical flavonoids.

    It has been suggested that some of the symptoms typically attributed to menopause may be more related to premenstrual syndrome (PMS) than menopause, as perimenopausal women appear to be more prone to PMS-like symptoms, or at least to tolerate them less well. The objective of this study was to evaluate the effectiveness of a phytotherapeutic intervention comprising a combination of Hypericum perforatum (St. John's wort) and Vitex agnus-castus (chaste tree/berry) in the management of PMS-like symptoms in perimenopausal women. A double-blind, randomized, placebo-controlled parallel trial was conducted over 16 weeks on menopause-related symptoms. Data on PMS-like symptoms were collected at 4-weekly intervals from a small subgroup of late-perimenopausal women (n = 14) participating in this study. The primary endpoint was PMS scores measured on the Abrahams Menstrual Symptoms Questionnaire, comprising the subclusters of PMS-A (anxiety), PMS-D (depression), PMS-H (hydration), and PMS-C (cravings). Herbal combination therapy or placebo tablets were administered twice daily. At the end of the 16-week treatment phase, analyses of covariance showed the herbal combination to be superior to placebo for total PMS-like scores (p = 0.02), PMS-D (p = 0.006), and PMS-C clusters (p = 0.027). The active treatment group also showed significant reductions in the anxiety (p = 0.003) and hydration (p = 0.002) clusters, using paired-samples t tests. Results of trend analyses showed significant treatment group effects across the five phases for total PMS and all subscales, all in the clinically expected direction. No significant trends were evident in the placebo group. These results suggest a potentially significant clinical application for this phytotherapeutic combination in PMS-like symptoms among perimenopausal women. Further research is warranted through a randomized, controlled trial dedicated to investigation of these symptoms.

    Topical Acyclovir has moderate efficacy on recurrent HSV symptoms, requiring repeat applications for several days. Topical Dynamiclear, which requires only a single dose application, may provide a more effective and convenient treatment option for symptomatic management of HSV. The study assessed the comparative efficacy and tolerability of a single use, topical formulation containing copper sulfate pentahydrate and Hypericum perforatum that is marketed as Dynamiclear™ to a topical 5% Acyclovir cream standard preparation and use. A prospective, randomized, multi-centered, comparative, open-label clinical study was conducted. A total of 149 participants between 18 and 55 years of age with active HSV-1 and HSV-2 lesions were recruited for the 14-day clinical trial. Participants were randomized into two groups: A (n=61), those receiving the Dynamiclear formulation, and B (n=59), those receiving 5% Acyclovir. Efficacy parameters were assessed via physical examination at baseline (day 1), day 2, 3, 8, and 14. Laboratory safety tests were conducted at baseline and on day 14. Use of the Dynamiclear formulation was found to have no significant adverse effects and was well tolerated by participants. All hematological and biochemical markers were within normal range for the Dynamiclear group. Statistically, odds for being affected by burning and stinging sensation were 1.9 times greater in the Acyclovir group in comparison to the Dynamiclear group. Similarly, the odds of being affected by symptoms of acute pain, erythema and vesiculation were 1.8, 2.4, and 4.4 times higher in the Acyclovir group in comparison to the Dynamiclear group. The Dynamiclear formulation was well tolerated, and efficacy was demonstrated in a number of measured parameters, which are helpful in the symptomatic management of HSV-1 and HSV-2 lesions in adult patients. Remarkably, the effects seen from this product came from a single application.

    Hypericum perforatum (hiperico) is a plant that has been used to treat diseases and also inhibits rat and human vas deferens contractility. In nuclear medicine, stannous chloride (SnCl 2 ) is used as a reducing agent to obtain radiopharmaceuticals labeling with technetium-99m. As the SnCl 2 seems to have adverse effects related with the reproductive performance of male rabbits as well as the human consumption of hiperico might affect sexual function. In the present work, consistent results show significant changes on the blood constituents labeled by technetium-99m obtained from young rats under the effect of an hiperico extract as opposed to blood samples equally treated taken from elderly rat. Supposedly, this extract could protect the male reproductive system against action of SnCl 2 at least in young rats. The findings described in this work allow introducing a simple assay to evaluate the action of products that could interfere with the male reproductive system. (author)

    Full Text Available Introduction: Among the heavy metals, cadmium, because of high mobility and bioavailability in soil and also toxicity at low concentrations is very important. Cadmium (Cd is known as carcinogen and can induce many types of cancers. Human activities (metallic industries, contaminated fertilizer, herbicides or insecticides, irrigation with contaminated groundwater, and use of contaminated sewage sludge are largely responsible for accumulation of different levels of Cd in soil. Saint John’s Wort (Hypericum perforatum L. is a medicinal plant and belongs to the family Hypericaceae which its extract, one of the best-characterized herbal medicines, known as the Cd-hyperaccumulator, is widely sold for the treatment of depression. Hyperaccumulator plants are species able to accumulate high amounts of heavy metals in their tissue at concentrations of 10 to 100 times higher than tolerated by crop plants. Zinc (Zn is an essential element occurring in several enzymes, where it plays a catalytic or structural role. Cadmium and zinc have similar electron configuration, valence state as well as affinity to S, N and O donor ligands and thus their geochemical and environmental properties are comparable. The antagonism activity between Cd and Zn in the environment and their chemical similarity can lead to interactions between Cd and Zn during plant uptake, transport from roots to shoots, or accumulation in edible tissues. Ion exchange is one of the methods used for the removal of several toxic substances. In recent years, natural amendments, such as zeolite have been widely used to address trace metals contamination. Therefore, adding zinc and zeolite to the growth medium of plant can be moderating the toxic effects of cadmium. Materials and Methods: This pot experiment was conducted at the Experimental Field of Ferdowsi University of Mashhad (FUM from September 2013 to June 2014. Treatments consisted of three levels of cadmium (0, 10 and 20 mg Cd kg-1 soil

    Full Text Available Hypericumperforatum (H. perforatum ethanol extract has been found to inhibit lipopolysaccharide-induced production of inflammatory mediators and cytokines in cultured macrophages. Therefore, it may be able to protect the host from excessive inflammation during viral infection. In the current study, the immune-regulatory effect of H. perforatum extract was evaluated in A549 lung epithelial cells and BALB/c mice exposed to Influenza A/PR/8/34 H1N1 virus. In A549 cells, the extract (30 µg/mL significantly inhibited influenza virus induced monocyte chemotactic protein (MCP-1 and interferon-γ induced protein 10 kD (IP-10, but dramatically increased interleukin-6 (IL-6. In mice inoculated intranasally with 10(7.9 EID50 of Influenza A/PR/8/34 H1N1 (high dose, daily oral treatment of H. perforatum extract at a rate of 110 mg/kg of body weight increased lung viral titer, bronchoalveolar lavage (BAL pro-inflammatory cytokine and chemokine levels, and the infiltration of pro-inflammatory cells in the lung 5 days post-inoculation, as compared to ethanol vehicle treated mice. Transcription of suppressor of cytokine signaling 3 (SOCS3 was increased by H. perforatum extract both in A549 cells and BALB/c mice, which could have interrupted anti-viral immune response and thus led to the inefficient viral clearance and increased lung inflammation. H. perforatum treatment resulted in minor reduction in viral titer without affecting body weight when mice were inoculated with a lower dose (~10(5.0 EID50 and H. perforatum was applied in the later phase of infection. Mice challenged intranasally with high dose of influenza virus (10(7.9 EID50 suffered from a higher mortality rate when dosed with H. perforatum extract. In conclusion, the current study showed that SOCS3 elevation by H. perforatum may cause impaired immune defense against influenza virus infection and lead to higher mortality.

    Corolla chirality, the pinwheel arrangement of petals within a flower, is found throughout the core eudicots. In 15 families, different chiral type flowers (i.e., right or left rotated corolla) exist on the same plant, and this condition is referred to as unfixed/enantiomorphic corolla chirality. There are no investigations on the significance of unfixed floral chirality on directed pollen movement even though analogous mirror image floral designs, for example, enantiostyly, has evolved in response to selection to direct pollinator and pollen movement. Here, we examine the role of corolla chirality on directing pollen transfer, pollinator behavior, and its potential influence on disassortative mating. We quantified pollen transfer and pollinator behavior and movement for both right and left rotated flowers in two populations of Hypericum perforatum. In addition, we quantified the number of right and left rotated flowers at the individual level. Pollinators were indifferent to corolla chirality resulting in no difference in pollen deposition between right and left flowers. Corolla chirality had no effect on pollinator and pollen movement between and within chiral morphs. Unlike other mirror image floral designs, corolla chirality appears to play no role in promoting disassortative mating in this species.

    Full Text Available Abstract Background: Resistance of Acanthamoeba cysts causes recurrence of the disease; so, the patient should be monitored regularly ،The aim of the study was to examine the effect of a few herbal materials on Acanthamoeba cysts in vitro. Materials and Methods: Essential oils (EOs of Zataria, Mint, and Oregano were prepared by steam distillation. The EOs and Hypericum perforatum extract were prepared in three concentrations (0.6%, 1% and 10%، Acanthamoeba cysts in various time intervals (30, 60, 120, 180 and 1440 minutes were exposed with plant extracts. Then, the viability of parasite was investigated by eosin 0.1%. Results: Comparison of the parasite mortality rate between control and case groups showed that the mortality of Acanthamoeba cysts was higher in the case groups that exposed to herbal materials. At the equal concentration (10% and time (24 h, the Zataria and mint EOs produced the highest (22% and lowest (4% mortality, respectively. The results showed the mortality rate of Acanthamoeba was time-dependent. Conclusion: Zataria showed the most fatality effect against Acanthamoeba cysts. In this respect, clinical trial studies are suggested.

    Full Text Available Nos últimos anos, o interesse por Hypericum perforatum tem aumentado devido à sua ação antiviral, antidepressiva e moduladora de apoptose em células neoplásicas. O preparo do material vegetal, após ser colhido, envolve freqüentemente a dessecação ou o congelamento e posterior armazenamento, processos que podem alterar o perfil dos metabólitos secundários. Neste sentido, este trabalho avaliou o efeito da secagem, do congelamento e da estocagem sob baixas temperaturas na quantidade de flavonóides e de hipericina nas partes vegetativas de plantas de hipérico. Ramos de hipérico foram submetidos à secagem a 25, 30, 50 e 70 °C, congelados em nitrogênio líquido ou congelados e armazenados a -20 °C por 10, 20 e 30 dias. A quantificação dos flavonóides e de hipericina foi realizada por cromatografia líquida de alta eficiência (CLAE. Os teores de flavonóides e de hipericina foram afetados pela temperatura de secagem. Secagem a 25 °C causou redução nos teores de grande parte dos metabólitos analisados, enquanto a 50 °C, os teores de rutina livre e glicosilada, de quercetina e quercitrina glicosiladas e de hipericina foram preservados. Apigenina livre e canferol não sofreram reduções significativas nas suas concentrações, independente das temperaturas de secagem. O tratamento de congelamento e imediata análise das amostras não alterou o perfil dos flavonóides, mas causou redução do nível de hipericina nas plantas de hipérico.In recent years, interest in Hypericum perforatum has increased due to its antiviral, antidepressive and apoptosis-inducing properties. Plant material preparation after harvesting often includes dehydration or freezing and further storage, and these procedures can lead to variations in the secondary metabolite profile.

    Full Text Available The genus Hypericum includes over 500 widely distributed species. The main representative is St. John’s wort (Hypericum perforatum L. (1753, Hypericaceae, the only approved biological source of Hyperici herba by WHO and EMEA monographs. It is frequently used in the form of oil macerate for treatment of burns, scars, eczema and gas­trointestinal disorders, as well as in the form of water and alcoholic extracts as clinically proved antidepressant. Available data suggest that the amounts of secondary metabolites in the plant vary depending on ecological factors of the habitat, and consequently affect the quality of herbal drug. The reports show that other species of the genus have similar chemical profile as H. perforatum. But, there are also Hypericum species in which some of the secondary metabolites of interest occur in higher quantities than in H. perforatum. As previous data suggest, Hypericum hirsutum L. 1753, could be such example. Therefore, the aim of this study was to chemically characterize water-alcoholic extracts of H. hirsutum samples, collected at four localities in Vojvodina (Republic of Serbia by liquid chromatography (HPLC-DAD. The obtained results suggest a good match (in a term of a presence of investigated compounds of previously published results describing chemical profile of H. perforatum water-alcoholic extracts with examined H. hirsutum extracts. Also, chemotaxonomic analysis showed variations in quantity of secondary metabolites in the examined extracts. This opens the door to further investigation of H. hirsutum as a new source of bioactive secondary metabolites and additional markers in Hypericum chemotaxonomy.

    Plant extracts such as Hypericum perforatum and Pycnogenol have been tested as alternatives to the classical ADHD drugs. It has been possible to describe neuroprotective effects of such plant extracts. A reduction of ADHD symptoms could be shown in clinical studies after the application of Pycnogenol, which is a pine bark extract. The impacts of the standardized herbal extracts Hypericum perforatum, Pycnogenol and Enzogenol up to a concentration of 5000 ng/mL on cell survival and energy metabolism in human SH-SY5Y neuroblastoma cells has been investigated in the present examination. Hypericum perforatum significantly decreased the survival of cells after treatment with a concentration of 5000 ng/mL, whereas lower concentrations exerted no significant effects. Pycnogenol( induced a significant increase of cell survival after incubation with a concentration of 32.25 ng/mL and a concentration of 250 ng/mL. Other applied concentrations of Pycnogenol failed to exert significant effects. Treatment with Enzogenol did not lead to significant changes in cell survival.Concerning energy metabolism, the treatment of cells with a concentration of 5000 ng/mL Hypericum perforatum led to a significant increase of ATP levels, whereas treatment with a concentration of 500 ng/mL had no significant effect. Incubation of cells with Pycnogenol and Enzogenol exerted no significant effects.None of the tested substances caused any cytotoxic effect when used in therapeutically relevant concentrations.

    Hypericin (HYP) molecule is a natural photoactive pigment, which plays a role as an effective photoreceptor in some plants of the Hypericum species (the most common of which is Saint John’s Wort) and some insect species. The present work deals with the first attempt to the study of peroxyoxalate chemiluminescence (POCL) system in the presense of HYP as a natural fluorophore. Reaction of bis (2,4,6-trichlorophenyl) oxalate(TCPO)–H 2 O 2 –imidazole can transfer energy to a HYP via formation of dioxetane through the chemically initiated electron exchange luminescence (CIEEL) mechanism and can emits a very intense red light. The effects of HYP, hydrogen peroxide, TCPO and imidazole concentrations on kinetic chemiluminescence parameters were also studied. These parameters including rise and fall rate constant for the chemiluminescence burst, theoretical and experimental maximum intensity, theoretical and experimental time to reach maximum intensity and total light yield emission were evaluated by using a pooled intermediate model for a non-linear least-squares curve fitting program, KINFIT. Moreover, quenching effect of two lipophilic natural antioxidant, Quercetin and β-carotene on it system was also investigated. The measurable concentration range of 7×10 −6 M to 7.5×10 −5 M of antioxidants were evaluated from the proper Stern–Volmer plots with satisfactory RSD% and corresponding detection limits of 2.2×10 −6 and 3.7×10 −6 for β-carotene and quercetin respectively. - Highlights: ► Red fluorophores may therefore chemiluminescence more intensely than other commonly chemiluminophores and emits light in longer wavelengths. ► Hypericin from St. John’s wort (hypericum perforatum) as natural red fluorophore for peroxyoxalate chemiluminescence was introduced. ► Quenching effect of two antioxidant, quercetin and β-carotene on it system was also investigated. ► The non linear least-squares curve fitting program KINFIT was applied to study of CL

    Flower extracts of Hypericum perforatum, Hypericum hirsutum, Hypericum patulum and Hypericum olympicum efficiently inhibited binding of [3H]flumazenil to rat brain benzodiazepine binding sites of the GABAA-receptor in vitro with IC50 values of 6.83, 6.97, 13.2 and 6.14 micrograms/ml, respectively. Single constituents of the extracts like hypericin, the flavones quercetin and luteolin, the glycosylated flavonoides rutin, hyperoside and quercitrin and the biflavone 13, II8-biapigenin did not inhibit binding up to concentrations of 1 microM. In contrast, amentoflavone revealed an IC50 = 14.9 +/- 1.9 nM on benzodiazepine binding in vitro. Comparative HPLC analyses of hypericin and amentoflavone in extracts of different Hypericum species revealed a possible correlation between the amentoflavone concentration and the inhibition of flumazenil binding. For hypericin no such correlation was observed. Our experimental data demonstrate that amentoflavone, in contrast to hypericin, presents a very active compound with regard to the inhibition of [3H]-flumazenil binding in vitro and thus might be involved in the antidepressant effects of Hypericum perforatum extracts.

    Full Text Available Background: Hypericum perforatum or St. John’s wort is a plant known as a Raee flower (or Hypericum in Persian. Hyperisin and Hyperforin are the main constituents of this plant extract that are connected to sigma opioid and GABA receptors. Its various pharmacological effects, such as analgesia, sedation, anti-spasm, anti-convulsion, anti-anxiety, and anti-bacteria have already been known. Materials and Method: To conduct the study, the authors prepared the hydro alcohol extract taken from the aerial organ of the plant. Then, different groups of female Wistar rats, which were almost equal in age and weight, received doses of 500mg/kg and 250mg/kg of the extract, 1.2mg/kg of diazepam, and di-methyl solphoxid (as placebo with equal volumes. The intraperitoneal injections were administered 15min before assessing the sedative/hypnotic effects (i.e. duration of the induced sleep by ketamin with a dose of 40mg/kg and the anxiolytic effects by means of the elevated plus maze.Results: The results showed a statistically significant increase (p= 0.00 both in the duration of the induced sleep by ketamin and in the time lapsed in the open arms in the experimental groups with high and low doses of the extract.Conclusion: The findings suggest that the extract of Hypericum perforatum with a dose of 500mg/kg could have sedative, preanaesthetic, and anxiolytic effects.

    Full Text Available Na última década, o gênero Hypericum ganhou repercussão mundial devido à utilização de Hypericum perforatum para obtenção de medicamentos antidepressivos. Por esta razão, a maioria dos estudos com outras espécies do gênero centra-se nesta atividade. Porém, um dos usos populares de espécies de Hypericum nativas do sul do Brasil é no tratamento de problemas gastrintestinais, inclusive como antiespasmódico. Neste trabalho, foi avaliado o efeito de uma das espécies de Hypericum nativas do Rio Grande do Sul, H. caprifoliatum, sobre as contrações induzidas por agonistas em íleo isolado de cobaio. Foi investigado o efeito de um extrato ciclo-hexano purificado (isento de clorofila e ceras, nas concentrações de 1, 3, 10 e 30 mg/mL, sobre curvas cumulativas de acetilcolina, histamina, potássio e serotonina (10-7 a 10-4 M. Na concentração de 30 mg/mL o extrato inibiu totalmente as contrações induzidas por todos os agonistas. Na concentração de 10 mg/mL, o extrato apresentou efeito antagonista não-competitivo de serotonina, reduzindo a contração máxima induzida por serotonina em cerca de 50 %. A resposta contrátil aos outros mediadores não foi alterada. Estes resultados indicam que espécies de Hypericum do sul do Brasil podem ser uma perspectiva interessante na busca de moléculas com atividade sobre a motilidade gastrintestinal.

    Refractory carcinoma in situ and resistant multifocal transitional cell carcinoma (TCC) of the human urinary bladder respond modestly to PHOTOFRIN (PII) PDT. Hypericum perforatum L., (St. John"s wort /Epirus" Vasalmo, Greece), a medicinal plant used for many human ailments, is under investigation as a new photosensitizer. We have reported on the antiproliferative activity of the lipophilic extract of the Hypericum perforatum L. (HP) against cultured T-24, and NBT-11 bladder cancer cells. We investigated response of the polar methanolic fraction (PMF) of the HP extract versus PHOTOFRIN in photodynamic therapy (PDT) of human bladder cancer cells, RT-4 and T-24.The PMF was extracted from the dry herb with methanol, followed by liquid extraction with petroleum ether. RT-4/T-24, were plated (105 cells/well) and placed in the incubator (370 C, 5%CO) for 24 hours prior to addition of drugs. PII 2ug/ml, or PMF 60ug /ml was added and incubation continued. After 24 hours, the cells were treated with laser light (630nm) with 0,1,2,4 and 8 Joules. The cells were then washed and reincubated for another 24 hours. After this incubation cell survival was assessed by the MTT assay. PMF-PDT induced percent cell kill of 0%, 0%, 0%, 29% and 75%, in RT-4 cells (primary noninvasive urinary bladder TCC) versus 5%, 9%, 13%, 69% and 86%, in T-24 cells(metastatic TTC) at 0,1,2,4 and 8 Joules respectively. PII-PDT induced cell kill of 0 %, 0% ,0%,0% and 9 %, in RT-4 cells versus 0%,10%,0%,21% and 77%, in T-24 cells at 0,1,2,4 and 8 Joules respectively.RT-24 cells were relatively more resistant than T-24 cells to PMF and PII-PDT. Understanding mechanisms of such differential responses might prove useful

    extracts presented low cytotoxicity against murine macrophages. At 48h of incubation H. polyanthemum presented significant leishmanicidal activity with a 50% inhibitory concentration (IC50) of 36.1µg/ml. The leishmanicidal activity of H. myrianthum was significantly lower than that presented by H. polyanthemum, H. carinatum and H. linoides extracts. H. brevistylum and H. caprifoliatum showed significant leishmanicidal activity only at high concentrations (500 and 1000µg/ml), while H. andinum and H. silenoides were ineffective. The promising results demonstrate the importance of the species of the genus Hypericum as source of compounds potentially useful for the treatment of leishmaniasis. Copyright © 2014 Elsevier GmbH.

    Full Text Available Microencapsulation is a technique that allows liquid or solid agents, such as pharmaceutical agents, pesticides, insect repellent agents, dyes, cosmetics and fragrances, to be encapsulated by a suitable barrier wall. Liquid or solid agents that are encapsulated are called core material. The importance of functional finishes have been increasing rapidly in the World. Microencapsulation is an alternative way to achieve the functional finishes because of their unique properties, such as controlled release, protection against to hazardous and destructive media, and providing higher surface area. In this study, jojoba, jasmine and St. John's Wort oils, were encapsulated according to spray drying method. St. John's Wort and jojoba oils were used at 1:1 ratio as fixed oil. Jasmine essential oil was added to fixed oil mixture at two different ratios. After preparing the core mixture, encapsulation studies were performed three different core : wall ratios. Morphological analyses of microcapsules were carried out using SEM (Scanning Electron Microscope. FTIR spectroscopy spectrums of microcapsules were determined (Fourier Transform Infrared. Particle size distribution microcapsules were analyzed by laser scattering measurement method. DSC (Differential Scanning Calorimetry thermographs of microcapsules were obtained. All microcapsules were applied to 100% cotton knitted fabrics. Strength to washing of fabrics were observed by SEM micrographs.

    The adoption of the EU community monograph on Hypericum constitutes a milestone in the process of harmonisation of herbal medicinal products within the European Community. The assessment of the published clinical data revealed that for two types of extracts the evidence of the efficacy in mild to moderate depressive episodes compared to placebo or standard medication was found to be acceptable. Additionally, a sufficient efficacy in relapse prophylaxis could be demonstrated for these two herbal preparations. For some other dry extracts, the efficacy in the short-term treatment of symptoms in mild depressive disorders was found to be substantiated. Short-term treatment with preparations containing low amounts of hyperforin did not increase cytochrome P450 enzyme activity. Therefore the oral administration of traditional herbal preparations is restricted to two weeks. In the case that an applicant demonstrates that the daily intake of hyperforin is below 1 mg the warnings on interactions may be omitted in traditional herbal medicinal products. Additionally the cutaneous administration of traditional liquid herbal preparations for the traditional use in symptomatic treatment of minor inflammations of the skin and as an aid in healing minor wounds was included in the monograph.

    Burning mouth syndrome (BMS) is a chronic oral pain syndrome that primarily affects peri- and postmenopausal women. It is characterized by oral mucosal burning and may be associated with dysgeusia, paresthesia, dysesthesia, and xerostomia. The etiology of the disease process is unknown, but is thought to be neuropathic in origin. The goal of this systematic review was to assess the efficacy of the various treatments for BMS. Literature searches were conducted through PubMed, Web of Science, and Cochrane Library databases, which identified 22 randomized controlled trials. Eight studies examined alpha-lipoic acid (ALA), three clonazepam, three psychotherapy, and two capsaicin, which all showed modest evidence of potentially decreasing pain/burning. Gabapentin was seen in one study to work alone and synergistically with ALA. Other treatments included vitamins, benzydamine hydrochloride, bupivacaine, Catuama, olive oil, trazodone, urea, and Hypericum perforatum. Of these other treatments, Catuama and bupivacaine were the only ones with significant positive results in symptom improvement. ALA, topical clonazepam, gabapentin, and psychotherapy may provide modest relief of pain in BMS. Gabapentin may also boost the effect of ALA. Capsaicin is limited by its side effects. Catuama showed potential for benefit. Future studies with standardized methodology and outcomes containing more patients are needed. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    1994-10-01

    The inhibition of monoamine oxidase (MAO) by six fractions from hypericum extract and three characteristic constituents (as pure substances) were analyzed in vitro and ex vivo to study the antidepressive mechanism of action. Rat brain homogenates were used as the in vitro model, while the ex vivo analysis was performed after intraperitoneal application of the test substances to albino rats. Massive inhibition of MAO-A could be shown with the total extract and all fractions only at the concentration of 10(-3) mol/L. At 10(-4) mol/L, one fraction rich in flavonoides showed an inhibition of 39%, and all other fractions demonstrated less than 25% inhibition. Using pure hypericin as well as in all ex vivo experiments, no relevant inhibiting effects could be shown. From the results it can be concluded that the clinically proven antidepressive effect of hypericum extract cannot be explained in terms of MAO inhibition.

    A photodynamic approach has been suggested to improve diagnosis and therapy of ovarian cancer. As Hypericin (Hy), a natural photosensitizer (PS) extracted from Hypericum perforatum, has been shown to be efficient in vitro and in vivo for the detection or treatment of other cancers, Hy could also be a potent tool for the treatment and detection of ovarian cancer. Due to its hydrophobicity, systemic administration of Hy is problematic. Thus, polymeric nanoparticles (NPs) of polylactic acid (PLA) or polylactic-co-glycolic acid (PLGA) were used as a drug delivery system. Hy-loaded NPs were produced with the following characteristics: (i) size in the 200-300 nm range, (ii) negative zeta potential, (iii) low residual PVAL and (iv) drug loading from 0.03 to 0.15% (w/w). Their in vitro photoactivity was investigated on the NuTu-19 ovarian cancer cell model derived from Fischer 344 rats and compared to free drug. Hy-loaded PLA NPs exhibited a higher photoactivity than free drug. Increasing light dose or incubation time with cells induced an enhanced activity of Hy-loaded PLA NPs. Increased NP drug loading had a negative effect on their photoactivity on NuTu-19 cells: at the same Hy concentration, the higher was the drug loading, the lower was the phototoxic effect. The influence of NP drug loading on the Hy release from NPs was also investigated.

    This paper provides a 10-year update of the 2007 systematic review of herbal medicines studied in a broad range of psychiatric disorders, including depression, anxiety, obsessive-compulsive, seasonal affective, bipolar, psychotic, phobic, somatoform, and attention-deficit hyperactivity disorders. Ovid Medline, PubMed, and the Cochrane Library were searched for herbal medicines with both pharmacological and clinical evidence of psychotropic activity. This updated review now covers clinical trial evidence for 24 herbal medicines in 11 psychiatric disorders. High-quality evidence was found to exist for the use of Piper methysticum (Kava), Passiflora spp. (passionflower) and Galphimia glauca (galphimia) for anxiety disorders; and Hypericum perforatum (St John's wort) and Crocus sativus (saffron) for major depressive disorder. Other encouraging herbal medicines with preliminary evidence include Curcuma longa (turmeric) in depression, Withania somnifera (ashwagandha) in affective disorders, and Ginkgo biloba (ginkgo) as an adjunctive treatment in Schizophrenia. Although depression and anxiety are commonly researched, many other mental disorders still require further prospective investigation. Although the previous review suggested increasing the adjunctive study of select herbal medicines with pharmaceuticals, this was still only found to sparingly occur in research designs. Aside from this, future focus should involve the incorporation of more biomarker analysis, in particular pharmacogenomics, to determine genetic factors moderating response to herbal medicines.

    Full text : As atomic power is increasingly recognized as a potential energy source to sustain future human development, radiological protection of the environment will become an even more important environmental safety concern. Thus, an understanding of the effects of ionizing radiation on non-human biota is required by the International Commission on Radiological Protection for the radiological protection of the environment. Soil processes are vital to sustainable terrestrial ecosystems, and soil invertebrates play an important role in nutrient cycling by feeding on microbiota. Because of their ecological importance, soil invertebrates are used for ecological impact assessments of terrestrial ecosystem pollutants. For chemical substances, single-species laboratory tests are used to understand toxicity. Standard tests using earthworms and spring tails have been developed by the Organization for Economic Co-operation and Development (OECD) and the International Organization for Standardization (ISO). Laboratory toxicity tests are also applicable in field contamination monitoring to determine if test organisms have been exposed to field-corrected soils. In such assays, gene expression as a biomarker has been receiving increased attention as it may produce fast, sensitive and diagnostic assays. A similar use of laboratory tests can be applied to assess the environmental impact of ionizing radiation. An understanding of the dose-effect relations of ionising radiation for non-human biota establishes important baselines for radiobiological protection of ecosystems. We used standard laboratory tests to examine dose-effect relationships of gamma radiation on the survival, biomass changing, feeding activity, coprolite excretion of aboriginal earthworms

    Polycyclic polyprenylated acylphloroglucinols (PPAPs) are a class of hybrid natural products sharing the mevalonate/methylerythritol phosphate and polyketide biosynthetic pathways and showing considerable structural and bioactive diversity. In a systematic phytochemical investigation of Hypericum henryi, 40 PPAP-type derivatives, including the new compounds hyphenrones G-Q, were obtained. These compounds represent 12 different structural types, including four unusual skeletons exemplified by 5, 8, 10, and 17. The 12 different core structures found are explicable in terms of their biosynthetic origin. The structure of a known PPAP, perforatumone, was revised to hyphenrone A (5) by NMR spectroscopic and biomimetic synthesis methods. Several compounds exhibited inhibitory activities against acetylcholinesterase and human tumor cell lines. This study deals with the structural diversity, function, and biogenesis of natural PPAPs.

    Background: The recent growth in knowledge of free radicals in biology is producing a medical revolution that promises a new age in health and disease management. In the last two decades there has been an explosive interest in the role of oxygen free radicals, more generally known as “reactive oxygen species” and of “reactive nitrogen species” in experimental and clinical medicine. Methods: The flowering top extract of Hypericum mysorense possessing potent anti-oxidant activity was subjected to bio-active guided isolation. Pulse radiolysis technique was used to determine the transient spectrum and rate constant for the one-electron oxidation of hyperoside by · OH, N 3 · , NO 2 · , NO · , CCl 3 OO · radicals in aqueous solution. Results: Three compounds were isolated and characterized as rutin, quercetin-3-O-galactoside (hyperoside) and quercetin from spectral analysis. The hyperoside radical showed pK a1 and pK a2 at 5.4 and 9.2. Both, Cu(II) and iron(II) ions form chelate with hyperoside. The Cu–hyperoside chelate was able to scavenge O 2 ·− , k=7.0(±0.3)×10 6 dm 3 mol −1 s −1 at pH 9. The repair rates for tryptophan and guanosine radicals by hyperoside were also determined. Conclusion: The reduction potential of hyperoside radical was determined by cyclic voltammetric and pulse radiolysis methods. - Highlights: • Hyperoside, rutin and quercetin were isolated from extract of Hypericum mysorense. • Rate constant of hyperoside was determined by Pulse radiolysis technique. • The hyperoside radical showed pK a1 and pK a2 at 5.4 and 9.2. • Cu(II) and iron(II)ions form chelate with hyperoside. • Hyperoside can repair the damage to guanosine, tryptophan radicals

    Full Text Available This studied examined the protective role of Hypericum scabrum oils (100 and 200 mg/kg b.w, i.p on acetaminophen-induced liver damages in the rat. The hepatic oxidative/antioxidant parameters such as lipid peroxidation (LP, glutathione (GSH, superoxide dismutase (SOD, catalase (CAT and ferric reducing ability of plasma (FRAP were measured 2, 4, 8, 16 and 24h after the treatments confirmed by histopathological consideration. The results indicated that increased levels of hepatic LP and FRAP and SOD activity were reversed in the rats treated with oils. In addition, the depleted GSH were compensated with the oil treatments. The protective effect of the oils was further confirmed by the histophatological examination carried out on liver biopsies. The data pointed out that H. scabrum oil could modulate the hepatic toxicity induced by the APAP through adjusting the oxidative stress/antioxidant parameters and could be of potential candidate for the treatment of acetaminophen induced oxidative stress liver damages.

    Full Text Available Antioxidants are compounds that obstruct the oxidation of macromolecules in the body. In general, there are two categories of antioxidants, natural and synthetic. Recently, interest has been increased considerably for obtaining new natural antioxidants. In this study, the scavenging of free radicals such as DPPH, NO and OH by Hypericum helianthemoides extract was evaluated. Also, the antioxidant properties of this extract were evaluated by FRAP, FTC methods and determination phenolic compounds. The plant was collected from north of Fars Province and plant extraction was obtained using ethanol. In DPPH radical scavenging, different concentrations of the Hypericum extract were added to DPPH radical. In hydroxyl radical scavenging, Fenton reaction mixture, TCA and TBA were mixed with Hypericum extract. In nitric radical scavenging, nitropruside was mixed with Hypericum extract and then sulphanilic acid, naphthylene diamine were added. In determination of phenolic compounds, Folin-ciocalteu and sodium carbonate were added to Hypericum extract. In DPPH radical scavenging, the IC50 of Hypericum extract (309.35±6.5μg/ml was higher than the antioxidant standards, BHT (IC50=81.9±2.6 μg/ml and quercetin (IC50=60.04±6.48 μg/ml. The highest scavenging of hydroxyl radicals was observed in Hypericum extract (70.3±0.8%, 125 μg/ml. In gallic acid it was (73.8±3.3%. In 200 μg/ml of Hypericum extract scavenged NO radical (85.2±2.7%. In FRAP method, the IC50 of this extract was 109.7±10.5 μg/ml. In FTC method, the inhibition of lipid peroxidation by Hypericum extract, BHT and ascorbic acid were 59.2±2.2, 66.9±0.15, 64.06±0.02 respectively. Total phenol of the plant extract was 3±0.4 mg/g.

    Cancer is an unnatural type of tissue growth in which the cells exhibit unrestrained division, leading to a progressive increase in the number of dividing cells. It is now the second largest cause of death in the world. The present study concerned antioxidant, anticancer and anticholinesterase activities and protocatechuic, catechin, caffeic acid, syringic acid, p-coumaric acid and o-coumaric concentrations in methanol extracts of flowers, fruits and seeds of Hypericum amblysepalum. Antioxidant properties including free radical scavenging activity and reducing power, and amounts of total phenolic compounds were evaluated using different tests. Protocatechuic, catechin, caffeic acid, syringic acid, p-coumaric acid and o-coumaric concentrations in extracts were determined by HPLC. Cytotoxic effects were determined using the MTT test with human cervix cancer (HeLa) and rat kidney epithelium cell (NRK-52E) lines. Acetyl and butyrylcholinesterase inhibitory activities were measured by by Ellman method. Total phenolic content of H. amblysepalum seeds was found to be higher than in fruit and flower extracts. DPPH free radical scavenging activity of the obtained extracts gave satisfactory results versus butylated hydroxyanisole and butylated hydroxytoluene as controls. Reducing power activity was linearly proportional to the studied concentration range: 10-500 μg/ mL LC50 values for H. amblysepalum seeds were 11.7 and 2.86 respectively for HeLa and NRK-52E cell lines. Butyryl-cholinesterase inhibitory activity was 76.9±0.41 for seed extract and higher than with other extracts. The present results suggested that H. amblysepalum could be a potential candidate anti-cancer drug for the treatment of human cervical cancer, and good source of natural antioxidants.

    Bioactive molecules isolated from plants are promising sources for the development of new therapies against leishmaniasis. We investigated the leishmanicidal activity of cariphenone A (1), isouliginosin B (2) and uliginosin B (3) isolated from Hypericum species. Promastigotes and amastigotes of Leishmania amazonensis were incubated with compounds 1-3 at concentrations 1-100 µ m for 48 h. The anti-promastigote effect of compounds was also tested in combinations. The cytotoxicity against macrophages and human erythrocytes were determined using the 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide (MTT) method and hemolysis assay, respectively. The compounds 1-3 showed high leishmanicidal activity against promastigotes, IC50 values of 10.5, 17.5 and 11.3 µ m, respectively. Synergistic interactions were found to the associations of compounds 1 and 2 [Σ fractional inhibitory concentration (FIC) = 0.41], and 2 and 3 (ΣFIC = 0.28) on promastigotes. All Hypericum compounds induced mitochondrial hyperpolarization and reactive oxygen species production in promastigotes. The compounds showed low cytotoxicity toward mammalian cells, high selectivity index and killed intracellular amastigotes probably mediated by oxidative stress. These results indicate that these compounds are promising candidates for the development of drugs against leishmaniasis.

    Hypericum ascyron L. (Great St. Johnswort), which belongs to the Hypericaceae family, has been used for the treatment of hematemesis, metrorrhagia, rheumatism, swelling, stomach ache, abscesses, dysentery and irregular menstruation for >2,000 years in China. The aim of the present study was to clarify the anticancer activity compounds from H. ascyron L. and the underlying molecular mechanism. Anticancer activity of H. ascyron L. extract was evaluated using an MTT assay. To confirm the anticancer mechanism of activity compounds, Hoechst 33258, Annexin V-fluorescein isothiocyanate/propidium iodide, 2',7'-dichlorodihydrofluorescein diacetate, rhodamine 123 staining and caspase-3 activity analysis were performed. The results demonstrated that the anti-proliferative action of the mixture of kaempferol 3-O-β-(2″-acetyl) galactopyranoside (K) and quercetin (Q) (molar ratio, 1:1) was significantly increased compared with either of these two compounds separately, and the active fraction of the H. ascyron L. extract |(HALE). HALE, indicating that the anti-proliferative function of H. ascyron L. may be a synergic effect of K and Q. Furthermore, the inhibitory effect of KQ on the growth of HeLa cells was mediated by the induction of apoptosis. To the best of our knowledge, the present study is the first to identify that KQ exhibits significant anti-proliferation activity on HeLa cells via the apoptotic pathway, and is also the first to evaluate the anticancer potential of H. ascyron L. The results of the present study may provide a rational base for the use of H. ascyron L. in the clinic, and shed light on the development of novel anticancer drugs.

    2013-01-01

    Background A number of bio-active secondary metabolites have been identified and reported for several Hypericum species. Many studies have reported the potential use of the plant extracts against several pathogens. However, Hypericum triquetrifolium is one of the least studied species for its antimicrobial activity. The aim of the present study was to evaluate the cytotoxic effect of the essential oils of Hypericum triquetrifolium as well as their antimicrobial potential against coxsakievirus B3 and a range of bacterial and fungal strains. Methods The essential oils of Hypericum triquetrifolium harvested from five different Tunisian localities (Fondouk DJedid, Bou Arada, Bahra, Fernana and Dhrea Ben Jouder) were evaluated for their antimicrobial activities by micro-broth dilution methods against bacterial and fungal strains. In addition, the cytotoxic effect and the antiviral activity of these oils were carried out using Vero cell lines and coxsakievirus B3. Results The results showed a good antibacterial activities against a wide range of bacterial strains, MIC values ranging between 0.39-12.50 mg/ml and MBC values between 1.56-25.0 mg/ml. In addition, the essential oils showed promising antifungal activity with MIC values ranging between 0.39 μg/mL and 12.50 μg/mL; MFC values ranged between 3.12 μg/mL and 25.00 μg/mL; a significant anticandidal activity was noted (MIC values comprised between 0.39 μg/mL and 12.50 μg/mL). Although their low cytotoxic effect (CC50 ranged between 0.58 mg/mL and 12.00 mg/mL), the essential oils did not show antiviral activity against coxsakievirus B3. Conclusion The essential oils obtained from Hypericum triquetrifolium can be used as antimicrobial agents and could be safe at non cytotoxic doses. As shown for the tested essential oils, comparative analysis need to be undertaken to better characterize also the antimicrobial activities of Hypericum triquetrifolium extracts with different solvents as well as their

    Full Text Available Next generation sequencing technology (NGS rapidly developed research applications in thefield of plant functional genomics. Several Hypericum spp. with an aim to generate andenhance gene annotations especially for genes coding the enzymes supposedly included inbiosynthesis of valuable bioactive compounds were analyzed. The first de novo transcriptomeprofiling of H. annulatum Moris, H. tomentosum L., H. kalmianum L. and H. androsaemumL. leaves cultivated in vitro was accomplished. All four species with only limited genomicinformation were selected on the basis of differences in ability to synthesize hypericins andpresence of dark nodules accumulating these metabolites with purpose to enrich genomicbackground of Hypericum spp. H. annulatum was chosen because of high number of the darknodules and high content of hypericin. H. tomentosum leaves are typical for the presence ofonly 1-2 dark nodules localized in the apical part. Both H. kalmianum and H. androsaemumlack hypericin and have no dark nodules. Four separated datasets of the pair-end reads weregathered and used for de novo assembly by Trinity program. Assembled transcriptomes wereannotated to the public databases Swiss-Prot and non-redundant protein database (NCBI-nr.Gene ontology analysis was performed. Differences of expression levels in the marginaltissues with dark nodules and inner part of leaves lacking these nodules indicate a potentialgenetic background for hypericin formation as the presumed site of hypericin biosynthesis isin the cells adjacent to these structures. Altogether 165 contigs in H. annulatum and 100contigs in H. tomentosum were detected as significantly differentially expressed (P<0.05 andupregulated in the leaf rim tissues containing the dark nodules. The new sequenceshomologous to octaketide synthase and enzymes catalyzing phenolic oxidative couplingreactions indispensable for hypericin biosynthesis were discovered.

    Protein tyrosine phosphatase 1B (PTP1B) has been regarded asa target for the research and development of new drugs to treat type II diabetes and PTP1B inhibitors are potential lead compounds for this type of new drugs. A phytochemical investigation to obtain new PTP1B inhibitors resulted in the isolation of four new phloroglucinols, longistyliones A-D (1-4) from the aerial parts of Hypericum longistylum. The structures of 1-4 were elucidated on the basis of extensive 1D and 2D NMR spectroscopic data analysis, and the absolute configurations of these compounds were established by comparing their experimental electronic circular dichroism (ECD) spectra with those calculated by the time-dependent density functional theory method. Compounds 1-4 possess a rare polycyclic phloroglucinol skeleton. The following biological evaluation revealed that all of the compounds showed PTP1B inhibitory effects. The further molecular docking studies indicated the strong interactions between these bioactive compounds with the PTP1B protein, which revealed the possible mechanism of PTP1B inhibition of bioactive compounds. All of the results implied that these compounds are potentially useful for the treatment of type II diabetes. Copyright © 2017 Elsevier Inc. All rights reserved.

    2016-02-01

    Full Text Available Weed populations feature within-population genetic differences. Thus, evaluating mean responses in herbicide treated populations may miss ecologically significant individual responses. Since hormesis can likewise vary between individuals, this study investigated the hypothesis that herbicide hormesis within a high-density weed population is different among slowly-growing individuals, as compared to fast-growing individuals. In a dose-response experiment, Tripleurospermum perforatum (Mérat Lainz was exposed to 12 doses of Atlantis WG (mesosulfuron + iodosulfuron in 24 replicates (50 plants/replicate. Root/shoot growth responses were evaluated as dose-response relationships for the population mean, the 90-97th percentile of the population (fast-growing individuals, and the 5-10th percentile (slow-growing individuals. Growth responses were generally biphasic. Slow-growing individuals had more pronounced hormesis that occurred partially at lower doses as compared to the population mean. With fast-growing individuals, hormesis was instead less pronounced and partially shifted to higher doses. Hence, hormesis was primarily associated with a stimulation of slow-growing individuals, while fast-growing individuals contributed to a lesser extent to the hormetic population response in a dense stand in vitro. This discrepancy may have the potential to segregate an herbicide exposed population and alter its sensitivity in the long-run.

    Tyrosinase inhibitors are of far-ranging importance in cosmetics, medicinal products, and food industries. Peru is a diverse country with a wide variety of plants that may contain excellent anti-tyrosinase inhibitors. In the present study, the tyrosinase inhibitory properties of 50 medicinal plant extracts from Peru were investigated using tyrosinase assay. Among plant extracts, those that showed an inhibition rate >50% were Hypericum laricifolium Juss ., Taraxacum officinale F.H.Wigg ., and Muehlenbeckia vulcanica Meisn ., with H. laricifolium Juss. showing the greatest anti-tyrosinase activity. Although H. laricifolium Juss. has been widely used as a medicinal plant by Peruvians, little is known regarding its bioactive components and effects on tyrosinase activity. For this reason, we attempted to discover tyrosinase inhibitors in H. laricifolium Juss. for the first time. The bioactive components were separated by Sephadex LH-20 chromatography and eluted with 100% methanol. Eight compounds were discovered and characterized by high-performance liquid chromatography coupled with diode array detection (HPLC-DAD): protocatechuic acid, p -hydroxybenzoic acid, chlorogenic acid, vanilic acid, caffeic acid, kaempferol 3- O -glucuronide, quercetin, and kaempferol. In addition, the concentration of these compounds required for 50% inhibition (IC 50 ) of tyrosinase activity were evaluated. Quercetin exhibited the strongest tyrosinase inhibition (IC 50 14.29 ± 0.3 μM). Therefore, the Peruvian plant H. laricifolium Juss. could be a novel source for anti-tyrosinase activity.

    Through bioassay-guided fractionation of the extracts from the aerial parts of the Chinese herb Hypericum japonicum Thunb. Murray, Isojacareubin (ISJ) was characterized as a potent antibacterial compound against the clinical methicillin-resistant Staphylococcus aureus (MRSA). The broth microdilution assay was used to determine the minimal inhibitory concentrations (MICs) and minimal bactericidal concentrations (MBCs) of ISJ alone. The results showed that its MICs/MBCs ranged from 4/16 to 16/64 μg/mL, with the concentrations required to inhibit or kill 50% of the strains (MIC(50)/MBC(50)) at 8/16 μg/mL. Synergistic evaluations of this compound with four conventional antibacterial agents representing different types were performed by the chequerboard and time-kill tests. The chequerboard method showed significant synergy effects when ISJ was combined with Ceftazidime (CAZ), Levofloxacin (LEV) and Ampicillin (AMP), with the values of 50% of the fractional inhibitory concentration indices (FICI(50)) at 0.25, 0.37 and 0.37, respectively. Combined bactericidal activities were also observed in the time-kill dynamic assay. The results showed the ability of ISJ to reduce MRSA viable counts by log(10)CFU/mL at 24 h of incubation at a concentration of 1 × MIC were 1.5 (LEV, additivity), 0.92 (CAZ, indifference) and 0.82 (AMP, indifference), respectively. These in vitro anti-MRSA activities of ISJ alone and its synergy with conventional antibacterial agents demonstrated that ISJ enhanced their efficacy, which is of potential use for single and combinatory therapy of patients infected with MRSA.

    LC-UV and LC-MS analysis were used to study the phenolic composition of water extracts of Hypericum undulatum (HU) shoot cultures and wild-growing (WG) plants. Total phenolic content (TPC), determined using the Folin-Ciocalteu assay, and the antioxidant activity measured by two complementary methods were also performed for each sample. Mass spectrometry revealed several phenolics acids with quinic acid moieties, flavonols, mostly quercetin, luteolin and apigenin glycosides, flavan-3-ols (catechin and epicatechin) and the xanthonoid mangiferin. Differences in phenolic composition profile and TPC were found between the samples. The major phenolic in HU culture-growing (CG) samples is chlorogenic acid, followed by epicatechin, quercitrin and isoquercitrin. The WG plants presents hyperoside as the main phenolic, followed by isoquercitrin, chlorogenic acid and quercetin. The TPC and antioxidant activity were higher in samples from WG plants.

    Depressions are the most common psychiatric diseases. For treatment, plant extracts have been used for thousands of years: examples are extracts from the (sleeping) poppy (opium), deadly nightshade (Atropa belladonna), Indian hemp (hashish), henbane (hyoscyamine), thorn apple (scopolamine), and St. John's wort (hypericum oil). In addition, psychotherapeutic measures, like playing music, dancing, playing theatre, and also the temple sleep, were used. In the 19th century, the introduction of brome (1826), codeine (1832), chloral hydrate (1869), and paraldehyde (1882), as well as the barbiturates (at the turn of the century) introduced significant improvements in pharmacotherapy. The modern thymoleptica therapy started in 1957 with the introduction of imipramine. Now about 40 active antidepressants are marketed. New drug developments should be characterized mainly by an improvement in tolerance.

    The present study investigates the antioxidant, anticancer, anticholinesterase, anti-genotoxic activities and phenolic contents of flower, fruit and seed methanol extracts of Hypericum retusum AUCHER. The amounts of protocatechuic acid, catechin, caffeic acid and syringic acid in methanol extracts were determined by HPLC. Total phenolic content of H. retusum seed extract was found more than fruit and flower extracts. The DPPH free radical scavenging activity of flower and seed methanol extracts showed close activity versus BHT as control. Among three extracts of H. retusum only flower methanol extract was exhibited considerable cytotoxic activities against to HeLa and NRK-52E cell lines. Moreover, seed methanol extract showed both acetyl and butyrl-cholinesterase inhibitory activity. The highest anti-genotoxic effects were seen 25 and 50 μg/mL concentrations. In this study, the extracts showed a strong antioxidant and anti-genotoxic effect. The seed extract was more efficient- than extracts of fruit and flowers. Our results suggest that the antioxidant and anti-genotoxic effects of extracts depend on their phenolic contents. Further studies should evaluate the in-vitro and in-vivo the benefits of H. retusum seed methanol extracts.

    Full Text Available Through bioassay-guided fractionation of the extracts from the aerial parts of the Chinese herb Hypericum japonicum Thunb. Murray, Isojacareubin (ISJ was characterized as a potent antibacterial compound against the clinical methicillin-resistant Staphylococcus aureus (MRSA. The broth microdilution assay was used to determine the minimal inhibitory concentrations (MICs and minimal bactericidal concentrations (MBCs of ISJ alone. The results showed that its MICs/MBCs ranged from 4/16 to 16/64 μg/mL, with the concentrations required to inhibit or kill 50% of the strains (MIC50/MBC50 at 8/16 μg/mL. Synergistic evaluations of this compound with four conventional antibacterial agents representing different types were performed by the chequerboard and time-kill tests. The chequerboard method showed significant synergy effects when ISJ was combined with Ceftazidime (CAZ, Levofloxacin (LEV and Ampicillin (AMP, with the values of 50% of the fractional inhibitory concentration indices (FICI50 at 0.25, 0.37 and 0.37, respectively. Combined bactericidal activities were also observed in the time-kill dynamic assay. The results showed the ability of ISJ to reduce MRSA viable counts by log10CFU/mL at 24 h of incubation at a concentration of 1 × MIC were 1.5 (LEV, additivity, 0.92 (CAZ, indifference and 0.82 (AMP, indifference, respectively. These in vitro anti-MRSA activities of ISJ alone and its synergy with conventional antibacterial agents demonstrated that ISJ enhanced their efficacy, which is of potential use for single and combinatory therapy of patients infected with MRSA.

    Hyperforin is one of the possible active principles mediating the antidepressant activity of Hypericum perforatum L. extracts. The ester derivative IDN 5491 (hyperforin-trimethoxybenzoate) showed antidepressant-like properties in the forced swimming test (FST) in rats, with no effect on open-field activity, when given as three intraperitoneal injections in 24 h at 3.125 and 6.25 mg/kg. The plasma concentrations of IDN 5491 were 30-50 microM, and those of hyperforin much lower but still close to those after effective doses of hyperforin-dicyclohexylammonium and Hypericum extract. This suggests that hyperforin plays a role in the antidepressant-like effect of the ester and of Hypericum extract. In vitro binding and uptake data showed that IDN 5491 is inactive on a wide panel of CNS targets at a concentration (14 microM) much higher than that measured in the brain of treated rats (0.3 microM). Like the extract, the antidepressant-like effect of IDN 5491 was blocked by (-)-sulpiride, a selective D2 receptor antagonist and by BD-1047, a selective sigma1 antagonist. Ex-vivo binding studies showed that brain sigma1 receptors are occupied after in vivo treatment with IDN 5491, possibly by an unknown metabolite or by endogenous ligand induced by hyperforin.

    The 17-item Hamilton Rating Scale for Depression (HAMD-17) Anxiety/Somatization factor includes six items: Anxiety (psychic), Anxiety (somatic), Somatic Symptoms (gastrointestinal), Somatic Symptoms (general), Hypochondriasis and Insight. This study examines the relationship between early changes (defined as those observed between baseline and week 1) in these HAMD-17 Anxiety/Somatization Factor items and treatment outcome among major depressive disorder (MDD) patients who participated in a study comparing the antidepressant efficacy of a standardized extract of hypericum with both placebo and fluoxetine. Following a 1-week, single-blind washout, patients with MDD diagnosed by the Structured Clinical Interview for DSM-IV (SCID) were randomized to 12 weeks of double-blind treatment with hypericum extract (900 mg/day), fluoxetine (20 mg/day) or placebo. The relationship between early changes in HAMD-17 anxiety/somatization factor items and treatment outcome was assessed separately for patients who received study treatment (hypericum or fluoxetine) versus placebo with a logistic regression method. One hundred and thirty-five patients (female 57%, mean age=37.3+/-11.0 years; mean baseline HAMD-17=19.7+/-3.2 years) were randomized to double-blind treatment and were included in the intent-to-treat (ITT) analyses. After adjusting for baseline HAMD-17 scores and for multiple comparisons with the Bonferroni correction, patients who remitted (HAMD-17 score Somatic Symptoms (General) scores than non-remitters. No other significant differences in early changes were noted for the remaining items between remitters versus non-remitters who received active treatment. For patients treated with placebo, early change was not predictive of remission for any of the items after Bonferroni correction. In conclusion, the presence of early improvement on the HAMD-17 item concerning fatigue and general somatic symptoms is significantly predictive of achieving remission at endpoint with

    In this paper, a heart-cutting two-dimensional high-performance liquid chromatography coupled with the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) method was established for controlling the quality of different batches of Hypericum ascyron extract for the first time. In comparison with the common one-dimensional fingerprint, the second-dimensional fingerprint compiled additional spectral data and was hence more informative. The quality of H. ascyron extract was further evaluated by similarity measures and the same results were achieved, the correlation coefficients of the similarity of ten batches of H. ascyron extract were >0.99. Furthermore, we also evaluated the quality of the ten batches of H. ascyron extract by antibacterial activity. The result demonstrated that the quality of the ten batches of H. ascyron extract was not significantly different by MTT. Finally, we demonstrated that the second-dimensional fingerprint coupled with the MTT method was a more powerful tool to characterize the quality of samples of batch to batch. Therefore the proposed method could be used to comprehensively conduct the quality control of traditional Chinese medicines. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    Hypericum perforatum L. (Hypericaceae), or St. John's Wort, is a well-known medicinal herb often associated with the treatment of anxiety and depression. Additionally, an oil macerate (Oleum Hyperici) of its flowering aerial parts is widely used in traditional medicine across the Balkans as a topical wound and ulcer salve. Other studies have shown that Oleum Hyperici reduces both wound size and healing time. Of its active constituents, the naphthodianthrone hypericin and phloroglucinol hyperforin are effective antibacterial compounds against various Gram-positive bacteria. However, hyperforin is unstable with light and heat, and thus should not be present in the light-aged oil macerate. Additionally, hypericin can cause phototoxic skin reactions if ingested or absorbed into the skin. Therefore, the established chemistry presents a paradox for this H. perforatum oil macerate: the hyperforin responsible for the antibacterial bioactivity should degrade in the sunlight as the traditional oil is prepared; alternately, if hypericin is present in established bioactive levels, then the oil macerate should cause photosensitivity, yet none is reported. In this research, various extracts of H. perforatum were compared to traditional oil macerates with regards to chemical composition and antibacterial activity (inhibition of growth, biofilm formation, and quorum sensing) vs. several strains of Staphylococcus aureus in order to better understand this traditional medicine. It was found that four Kosovar-crafted oil macerates were effective at inhibiting biofilm formation (MBIC 50 active range of 0.004-0.016% v/v), exhibited moderate inhibition of quorum sensing (QSIC 50 active range of 0.064-0.512% v/v), and contained detectable amounts of hyperforin, but not hypericin. Overall, levels of hypericin were much higher in the organic extracts, and these also exhibited more potent growth inhibitory activity. In conclusion, these data confirm that oil macerates employed in traditional

    The newly established instrumentation of HPLC/DAD, FTIR, and NMR techniques have been applied for simultaneous identification and physicochemical compatibility determination of the potential major antiseptic constituents ( Hypericum perforatum L. and Usnea barbata extracts) which can be present in some new origin pharmaceutical preparation. Based on the obtained results the conclusion is that a simultaneous use of the analyzed constituents in production of some new preparations with antiseptic properties is possible. The chromatographic separation of antiseptic mixture was performed on a RP-HPLC C18 column. For the NMR detection, the analytes eluted from LC column were trapped and hereafter transported into the NMR flow-cell. The NMR and FTIR techniques allowed the characterization of the major constituent of Hypericum perforatum L., mainly hypericin, as well as of Usnea barbata, mainly usnic acid.

    Radiation induced optic neuropathy (RION) is a rare but severe consequence of radiation therapy that is associated with adjuvant chemotherapy, specifically therapy with vincristine or nitrosoureas. However, there is very little evidence regarding the occurrence of RION after concomitant radiochemotherapy with temozolomide. The case of a 63 year old woman with glioblastoma multiforme and concomitant radiochemotherapy with temozolomide is described. Due to a slight depressive episode the patient also took hypericum perforatum. Five months after cessation of fractionated radiation and adjuvant chemotherapy with temozolomide (cumulative dose of 11040 mg) the patient developed bilateral amaurosis due to RION. Tumor regrowth was excluded by magnetic resonance imaging. After the application of gadolinium a pathognomonic contrast enhancement of both prechiasmatic optic nerves could be observed. In this patient, the occurrence of RION may have been the result of radiosensitization by temozolomide, which could have been strengthened by hypericin. Consequently, physicians should avoid a concomitant application of hypericum perforatum and radiochemotherapy

    Aims The efficacy of homeopathy is still under debate. The objective of this study was to assess the efficacy of homeopathic treatment (Arnica montana 5 CH, Bryonia alba 5 CH, Hypericum perforatum 5 CH and Ruta graveolens 3 DH) on cumulated morphine intake delivered by PCA over 24 h after knee ligament reconstruction. Methods This was an add-on randomized controlled study with three parallel groups: a double-blind homeopathic or placebo arm and an open-label noninterventional control arm. Eligible patients were 18–60 years old candidates for surgery of the anterior cruciate ligament. Treatment was administered the evening before surgery and continued for 3 days. The primary end-point was cumulated morphine intake delivered by PCA during the first 24 h inferior or superior/equal to 10 mg day−1. Results One hundred and fifty-eight patients were randomized (66 in the placebo arm, 67 in the homeopathic arm and 25 in the noninterventional group). There was no difference between the treated and the placebo group for primary end-point (mean (95% CI) 48% (35.8, 56.3), and 56% (43.7, 68.3), required less than 10 mg day−1 of morphine in each group, respectively). The homeopathy treatment had no effect on morphine intake between 24 and 72 h or on the visual analogue pain scale, or on quality of life assessed by the SF-36 questionnaire. In addition, these parameters were not different in patients enrolled in the open-label noninterventional control arm. Conclusions The complex of homeopathy tested in this study was not superior to placebo in reducing 24 h morphine consumption after knee ligament reconstruction. What is already known about this subject The efficacy of homeopathy is still under debate and a recent meta-analysis recommended further randomized double-blind clinical trials to identify any clinical situation in which homeopathy might be effective. What this study adds The complex of homeopathy tested in this study (Arnica montana 5 CH, Bryonia alba 5 CH

    The use of dietary supplements has increased and is associated with adverse effects. Indications for use include recreation, body image concerns, mood enhancement, or control of medical conditions. The risk of adverse effects may be enhanced if agents are used improperly. The objective of this study was to determine the frequency of abuse and misuse of 4 dietary substances among adolescents reported nationally to poison centers. Secondary outcomes included an assessment of medical outcomes, clinical effects, location of treatments provided, and treatments administered. This descriptive retrospective review assessed data concerning the use of garcinia (Garcinia cambogia), guarana (Paullinia cupana), salvia (Salvia divinorum), and St John's wort (Hypericum perforatum) among adolescents reported nationally to poison centers from 2003 to 2014. Adolescents with a singlesubstance exposure to one of the substances of interest coded as intentional abuse or misuse were included. Poison center calls for drug information or those with unrelated clinical effects were excluded. Data were collected from the National Poison Data System. There were 84 cases: 7 cases of Garcinia cambogia, 28 Paullinia cupana, 23 Salvia divinorum, and 26 Hypericum perforatum. Garcinia cambogia was used more frequently by females (100% versus 0%), and Paullinia cupana and Salvia divinorum were used more frequently by males (61% versus 36% and 91% versus 9%, respectively). Abuse, driven by Salvia divinorum, was more common overall than misuse. Abuse was also more common among males than females (p <0.001). Use of these agents fluctuated over time. Overall, use trended down since 2010, except for Garcinia cambogia use. In 62 cases (73.8%), the medical outcome was minor or had no effect or was judged as nontoxic or minimally toxic. Clinical effects were most common with Paullinia cupana and Salvia divinorum. Treatment sites included emergency department (n = 33; 39.3%), non-healthcare facility (n = 24

    Background Acute menopausal syndrome especially hot flashes, is one of the most common gynecological problems during menopause. Due to the side effects of hormone therapy, herbal and complementary medicines are always of immense interest to people in the treatment and management of the symptoms and complications of menopause. Objective The aim of this study was to investigate the mechanisms and effects of medicinal plants employed in the treatment of menopausal symptoms. Methods This review article was carried out by examining clinical trial studies between the period of 1994 and 2016. The keywords, which include menopause, climacteric, hot flushes, flashes, herb and phytoestrogens were used to search for herbal medicines used in clinical trials for the treatment of menopausal symptoms using databases such as PubMed, Medline, Scopus, Google scholar, SID and Magiran. Results The results of the study showed that the medicinal plants, which include Sage herb (Salvia officinalis), Lemon balm (Melissa officinalis), Valerina officinalis, Black cohosh (Cimicifuga racemosa), Fenugreek (Trigonella foenum-graecum), Black cumin (Nigella sativa), Vitex (Vitex agnus-castus), Fennel (Foeniculum vulgare), Evening primrose (Oenothera biennis), Ginkgo biloba, Alfalfa (Medicago sativa), Hypericum perforatum, Panax ginseng, Pimpinella anisum, Licorice (Glycyrrhiza glabra), Passiflora incarnata, Red clover (Trifolium pratense), and Glycine soja were effective in the treatment of acute menopausal syndrome with different mechanisms. Conclusion Medicinal plants can play an imperative role in the treatment of acute menopausal syndrome; however, further studies are required to buttress their efficacy in the treatment of acute menopausal syndrome.

    Full Text Available Abstract Background Several systematic reviews have summarized the evidence for specific treatments of primary care patients suffering from depression. However, it is not possible to answer the question how the available treatment options compare with each other as review methods differ. We aim to systematically review and compare the available evidence for the effectiveness of pharmacological, psychological, and combined treatments for patients with depressive disorders in primary care. Methods/Design To be included, studies have to be randomized trials comparing antidepressant medication (tricyclic antidepressants, selective serotonin reuptake inhibitors (SSRIs, hypericum extracts, other agents and/or psychological therapies (e.g. interpersonal psychotherapy, cognitive therapy, behavioural therapy, short dynamically-oriented psychotherapy with another active therapy, placebo or sham intervention, routine care or no treatment in primary care patients in the acute phase of a depressive episode. Main outcome measure is response after completion of acute phase treatment. Eligible studies will be identified from available systematic reviews, from searches in electronic databases (Medline, Embase and Central, trial registers, and citation tracking. Two reviewers will independently extract study data and assess the risk of bias using the Cochrane Collaboration's corresponding tool. Meta-analyses (random effects model, inverse variance weighting will be performed for direct comparisons of single interventions and for groups of similar interventions (e.g. SSRIs vs. tricyclics and defined time-windows (up to 3 months and above. If possible, a global analysis of the relative effectiveness of treatments will be estimated from all available direct and indirect evidence that is present in a network of treatments and comparisons. Discussion Practitioners do not only want to know whether there is evidence that a specific treatment is more effective than

    Full Text Available Medicinal and wild food plants have always played an important role in people’s lives especially in rural areas. Similar situation can be said for islands due to the reason of them being isolated from mainland. This paper reports an ethnobotanical investigations performed in 2009 and 2014 to determine medicinal and wild food plants of Marmara Island. A total of 30 individuals were interviewed (19 men, 11 women. Totally, 22 plants are recorded as used as traditional folk medicine for the region, and nine of these are also used as a source of wild food. Furthermore, 18 taxa are wild sources of nutrition for the area. The plants most commonly used in the region as medicinal remedies were Salvia fruticosa, Hypericum perforatum, Ficus carica, and Mentha spicata. Plants are mostly used for the treatment of abdominal pain, the common cold, and haemorrhoids. The species most commonly used for food are: Salvia fruticosa, Arbutus unedo, Rhus coriaria, and Rubus sanctus. This ethnobotanical study conducted in this island will enable the traditional use of wild plants both as food sources and herbal remedies to be passed on to future generations.

    Full Text Available The involvement of brain-derived neurotrophic factor (BDNF in different central nervous system (CNS diseases suggests that this neurotrophin may represent an interesting and reliable therapeutic target. Accordingly, the search for new compounds, also from natural sources, able to modulate BDNF has been increasingly explored. The present review considers the literature on the effects of botanicals on BDNF. Botanicals considered were Bacopa monnieri (L. Pennell, Coffea arabica L., Crocus sativus L., Eleutherococcus senticosus Maxim., Camellia sinensis (L. Kuntze (green tea, Ginkgo biloba L., Hypericum perforatum L., Olea europaea L. (olive oil, Panax ginseng C.A. Meyer, Rhodiola rosea L., Salvia miltiorrhiza Bunge, Vitis vinifera L., Withania somnifera (L. Dunal, and Perilla frutescens (L. Britton. The effect of the active principles responsible for the efficacy of the extracts is reviewed and discussed as well. The high number of articles published (more than one hundred manuscripts for 14 botanicals supports the growing interest in the use of natural products as BDNF modulators. The studies reported strengthen the hypothesis that botanicals may be considered useful modulators of BDNF in CNS diseases, without high side effects. Further clinical studies are mandatory to confirm botanicals as preventive agents or as useful adjuvant to the pharmacological treatment.

    Full Text Available Monoamine oxidase (MAO catalyzes the oxidative deamination of amines and neurotransmitters and is involved in mood disorders, depression, oxidative stress, and adverse pharmacological reactions. This work studies the inhibition of human MAO-A by Hypericum perforatum, Peganum harmala, and Lepidium meyenii, which are reported to improve and affect mood and mental conditions. Subsequently, the antioxidant activity associated with the inhibition of MAO is determined in plant extracts for the first time. H. perforatum inhibited human MAO-A, and extracts from flowers gave the highest inhibition (IC50 of 63.6 μg/mL. Plant extracts were analyzed by HPLC-DAD-MS and contained pseudohypericin, hypericin, hyperforin, adhyperforin, hyperfirin, and flavonoids. Hyperforin did not inhibit human MAO-A and hypericin was a poor inhibitor of this isoenzyme. Quercetin and flavonoids significantly contributed to MAO-A inhibition. P. harmala seed extracts highly inhibited MAO-A (IC50 of 49.9 μg/L, being a thousand times more potent than H. perforatum extracts owing to its content of β-carboline alkaloids (harmaline and harmine. L. meyenii root (maca extracts did not inhibit MAO-A. These plants may exert protective actions related to antioxidant effects. Results in this work show that P. harmala and H. perforatum extracts exhibit antioxidant activity associated with the inhibition of MAO (i.e., lower production of H2O2.

    At present the use of medicaments of plant origin is on the increase. It is therefore necessary to take into consideration that there exist known as well as potential interactions between the medicament of the medicinal plant. The problematic plants include Echinacea, Allium cepa, Gingko biloba, Panax ginseng, as well as Hypericum perforatum, Valeriana officinalis, or Glycyrrhiza glabra. Its use should be limited, or completely excluded in the cases of simultaneous therapy with, e.g., warfarin, hepatotoxically acting medicaments, MAOI inhibitors, phenelzin sulphate, or phenytoin, as they may decrease of completely eliminate the therapeutic effect of the administered drugs, or they may cause a toxic damage to the organism.

    The geographical and ecological specificity of the Balkan Peninsula has resulted in the development of a distinct diversity of medicinal plants. In the traditional culture of the Balkan peoples, plants have medicinal, economic and anthropological/cultural importance, which is reflected in the sound knowledge of their diversity and use. This study analyses the traditional use of medicinal plants in the treatment of wounds and the pharmacological characteristics of the most frequently used species. A detailed analysis of the literature related to ethnobhe uses of medicinal plants in the Balkan region was carried out. Twenty-five studies were analysed and those plants used for the treatment of wounds were singled out. An ethnobotanical analysis showed that 128 plant species (105 wild, 22 cultivated and 1 wild/cultivated) are used in the treatment of wounds. Their application is external, in the form of infusions, decoctions, tinctures, syrups, oils, ointments, and balms, or direct to the skin. Among those plants recorded, the most commonly used are Plantago major, Hypericum perforatum, Plantago lanceolata, Achillea millefolium, Calendula officinalis, Sambucus nigra, Tussilago farfara and Prunus domestica. The study showed that the traditional use of plants in wound healing is confirmed by in vitro and/or in vivo studies for P. major and P. lanceolata (3 laboratory studies for P. major and 2 for P. lanceolata), H. perforatum (5 laboratory studies and 3 clinical trials), A. millefolium (3 laboratory studies and one clinical trial), C. officinalis (6 laboratory studies and 1 clinical trial), S. nigra (3 laboratory studies) and T. farfara (one laboratory study). The beneficial effects of using medicinal plants from the Balkan region to heal wounds according to traditional practices have been proven in many scientific studies. However, information on the quantitative benefits to human health of using herbal medicines to heal wounds is still scarce or fragmented, hindering

    Complementary and Alternative Medicines (CAMs) are frequently given to children and adolescents for reputed benefits in the treatment of hyperkinetic and concentration disorders such as Attention Deficit Hyperactivity Disorder (ADHD). In such vulnerable populations high quality evidence is required to support such claims. The aim of the paper is to assess the current evidence of herbal and nutritional interventions for ADHD using a systematic search of clinical trials meeting an acceptable standard of evidence. PubMed, PsycINFO, Cochrane Library and CINAHL were searched up to May 26th, 2011 for randomised, controlled clinical trials using CAM products as interventions to treat ADHD. A quality analysis using a purpose-designed scale, and an estimation of effect sizes (Cohen's d) where data were available, were also calculated. The review revealed that 16 studies met inclusion criteria, with predominant evidentiary support found for zinc, iron, Pinus marinus (French maritime pine bark), and a Chinese herbal formula (Ningdong); and mixed (mainly inconclusive) evidence for omega-3, and l-acetyl carnitine. Current data suggest that Ginkgo biloba (ginkgo), and Hypercium perforatum (St. John's wort) are ineffective in treating ADHD. The research suggests only some CAMs may be beneficial in ADHD, thus clinicians need to be aware of the current evidence. Promising candidates for future research include Bacopa monniera (brahmi) and Piper methysticum (kava), providing potential efficacy in improving attentional and hyperkinetic disorders via a combination of cognitive enhancing and sedative effects.

    This study documents the ethnobotanical and ethnomedicinal importance of plants in the Suva planina mountain region (south-eastern Serbia). It is reflected in their high diversity and their wide range of uses in the treatment of the local population. The aim of this study was a comparative analysis of data collected in the Suva planina region with relevant data from the Western Balkans, which included identifying the 'most popular' plants, as well as those species which are used specifically for treatment solely in the research area. Ethnobotanical research was carried out between 2012 and 2014 and data was collected through both open and semi-structured interviews with locals. A total of 66 people were interviewed (37 women and 29 men), aged between 49 and 90 (with a mean age of 71). This study identified 128 plants and 2 fungi which are used in ethnomedicine, 5 plant species used in ethnoveterinary medicine, and 16 plants used for 'other' purposes. Lamiaceae (20), Asteraceae (17), Rosaceae (16), Brassicaceae (5), Alliaceae (4) and Apiaceae (4) have the greatest diversity of species. Results showed that Achillea mellefolium, Allium cepa, Allium sativum, Arctostaphyllos uva-ursi, Gentiana lutea, Hypericum perforatum, Juglans regia, Matricaria chamomilla, Mentha piperita, Plantago lanceolata, Plantago major, Salvia officinalis, Sempervivum tectorum, Tilia cordata and Thymus sepyllum are the 'most popular' medicinal plants (UV=1). Those plants with the most phytotherapeutic uses are Gentiana cruciata (14), H. perforatum (11) and A. sativum (10), while the most common conditions treated with medicinal plants are respiratory (79), urogenital (53), gastrointestinal (51), skin (43) and those relating to the circulatory system (35). A comparative analysis of the data collected in the research area and that from other parts of the Western Balkans showed that there are great similarities within Serbia between Suva planina and the Zlatibor region (37.2%) and Kopaonik Mt.

    2017-02-01

    Full Text Available Background: Plant extracts have been used in traditional medicine for the treatment of various maladies including neurological diseases. Several central nervous system receptors have been demonstrated to interact with plant extracts and components affecting the pharmacology and thereby potentially playing a role in human disease and treatment. For instance, extracts from Hypericum perforatum (St. John’s wort targeted several CNS receptors. Similarly, extracts from Piper nigrum, Stephania cambodica, and Styphnolobium japonicum exerted inhibition of agonist-induced activity of the human neurokinin-1 receptor. Methods: Different methods have been established for receptor binding and functional assays based on radioactive and fluorescence-labeled ligands in cell lines and primary cell cultures. Behavioral studies of the effect of plant extracts have been conducted in rodents. Plant extracts have further been subjected to mood and cognition studies in humans. Results: Mechanisms of action at molecular and cellular levels have been elucidated for medicinal plants in support of standardization of herbal products and identification of active extract compounds. In several studies, plant extracts demonstrated affinity to a number of CNS receptors in parallel indicating the complexity of this interaction. In vivo studies showed modifications of CNS receptor affinity and behavioral responses in animal models after treatment with medicinal herbs. Certain plant extracts demonstrated neuroprotection and enhanced cognitive performance, respectively, when evaluated in humans. Noteworthy, the penetration of plant extracts and their protective effect on the blood-brain-barrier are discussed. Conclusion: The affinity of plant extracts and their isolated compounds for CNS receptors indicates an important role for medicinal plants in the treatment of neurological disorders. Moreover, studies in animal and human models have confirmed a scientific basis for the

    Sea buckthorn (Hippophae rhamnoides L.) and St. John's wort (Hypericum perforatum L.) are used as an emmenagog and for the treatment of other gynecological disorders including uterus inflammation and endometriosis. The aim of the present study is to investigate the potential of a mixture of sea buckthorn and St. John's wort oils (HrHp oil) in the treatment of endometriosis. The activity was assessed in surgically induced endometriosis in rats. A 15-mm piece of endometrium was sutured into the abdominal wall. Twenty-eight days later, a second laparotomy was performed to calculate the endometrial foci areas and to score intra-abdominal adhesions. The rats were treated with either vehicle, HrHp oil formulation, or the reference (buserelin acetate). At the end of the experiment all rats were sacrificed and endometriotic foci areas and intra-abdominal adhesions were re-evaluated. The tissue sections were analyzed histopathologically. Peritoneal fluids of the experimental animals were collected in order to detect the levels of tumor necrosis factor-α, vascular endothelial growth factor, and interleukin-6, which might be involved in the etiology of endometriosis. In the HrHp oil-treated group, the volumes of endometriotic implants were found to be significantly decreased (from 50.8 mm 3 to 18.6 mm 3 , pnecrosis factor-α decreased from 7.02±1.33 pg/mL to 4.78±1.02 pg/mL (pvascular endothelial growth factor from 17.39±8.52 pg/mL to 9.67±5.04 pg/mL (ptreatment.

    Full Text Available Abstract Background Radiation induced optic neuropathy (RION is a rare but severe consequence of radiation therapy that is associated with adjuvant chemotherapy, specifically therapy with vincristine or nitrosoureas. However, there is very little evidence regarding the occurrence of RION after concomitant radiochemotherapy with temozolomide. Case Presentation The case of a 63 year old woman with glioblastoma multiforme and concomitant radiochemotherapy with temozolomide is described. Due to a slight depressive episode the patient also took hypericum perforatum. Five months after cessation of fractionated radiation and adjuvant chemotherapy with temozolomide (cumulative dose of 11040 mg the patient developed bilateral amaurosis due to RION. Tumor regrowth was excluded by magnetic resonance imaging. After the application of gadolinium a pathognomonic contrast enhancement of both prechiasmatic optic nerves could be observed. Conclusions In this patient, the occurrence of RION may have been the result of radiosensitization by temozolomide, which could have been strengthened by hypericin. Consequently, physicians should avoid a concomitant application of hypericum perforatum and radiochemotherapy.

    The anti-inflammatory, anti-microbial, antiviral, and antidepressant activities of the Greek herb, Hypericum Perforatum L, HP L, have been attributed to the total extract or single constituents. We investigated the use of the extract,specifically of the polar methanolic fraction (PMF) of Epirus"HPL in photodynamic therapy (PDT) alone and in combination with recombinant Interferon-a2b (IFN) and gemcitabine (GCB) in the treatment of human bladder cancer cells. The PMF was extracted from the dry herb with methanol, followed by liquid-liquid extraction with petroleum ether. T-24 bladder cancer cells were plated (105 cells/well) and placed in the incubator (370 C, 5%CO) for 24 hours prior to addition of drugs. PMF 60ug/ml was added and incubation continued. After 24 hours, the cells were subjected to laser light (630nm) treatment with 0, 1, 4 and 8 Joules. After reincubation for 24 hours, IFN, (50,000 IU) or GCB, (2ug/ml) was added to the PDT-treated cells. After this incubation cell survival was assessed by the MTT assay. PMF-PDT alone-induced percent cell kill of 0%, 8%, 44% and 80% versus 31%, 64 and 86 % for PMF-PDT and IFN, versus 63%, 80% and 88% for MPF-PDT plus GCB at 1, 2, 4 and 8 Joules respectively. IFN and GCB induced 20% and 53% cell kill respectively. Our data suggest that MPF may be an effective agent for in vitro photodynamic therapy. PMF-PDT combined with Intron A, or gemcitabine achieved improved kill of cultured bladder cancer cells. Confirmation of these results in preclinical studies may lead to clinical trials.

    The occurrence of potentially toxic pyrrolizidine alkaloids (PAs) in herbal medicines (HMs) is currently intensely being discussed in Europe. Pyrrolizidine alkaloids, particularly the 1,2-unsaturated PAs, are undesired compounds in HMs due to their potential hepatotoxic and carcinogenic properties. In this study, 98 widely patronized HMs from six popular German retail supermarkets/drugstores, as well as from pharmacies, were analyzed by high-performance liquid chromatography-electrospray ionization-tandem mass spectrometry for the presence of PAs. The results showed that about 63% of the HMs were PA positive, whereas the average PA concentration of the samples was 201 μg/kg, the highest concentration of PAs (3270 μg/kg) was attributed to a product that was purchased from the pharmacy and contained Hypericum perforatum L. (St. John's Wort) as an active ingredient. In addition, H. perforatum-containing products were frequently contaminated with PAs from Echium spp., while both Cynara cardunculus L. products and fixed-combination products of Gentiana lutea L., Rumex acetosa L., Verbena officinalis L., Sambucus nigra L., and Primula veris L. products were commonly contaminated with PAs of Senecio spp. The study showed that H. perforatum, C. cardunculus, Urtica dioica L., and fixed-combination products were frequently contaminated with PA levels above the recommended values of both the German and European Medicines Agencies.

    Herbal medicines are perceived to be safe by the general public and medical practitioners, despite abundant evidence from clinical trials and case reports that show herbal preparations can have significant adverse effects. The overall impact of adverse events to herbal medicines in Australia is currently unknown. Post marketing surveillance of medications through spontaneous adverse drug reaction (ADR) reports to the Therapeutic Goods Administration (TGA) is one way to estimate this risk. The patterns of spontaneously reported ADRs provide insight to herbal dangers, especially when compared with patterns of a mechanistically similar conventional drug. The study compared the pattern of spontaneously reported ADRs to St. John's Wort (Hypericum perforatum), a common herbal treatment for depression which contains selective serotonin reuptake inhibitors (SSRI), to fluoxetine, a commonly prescribed synthetic SSRI antidepressant. Spontaneous ADR reports sent to the TGA between 2000-2013 for St. John's Wort (n = 84) and fluoxetine (n = 447) were obtained and analysed. The demographic information, types of interaction, severity of the ADR, and the body systems affected (using the Anatomical Therapeutic Chemical classification system) were recorded for individual ADR cases. The majority of spontaneously reported ADRs for St. John's Wort and fluoxetine were concerning females aged 26-50 years (28.6%, 22.8%). The organ systems affected by ADRs to St John's Wort and fluoxetine have a similar profile, with the majority of cases affecting the central nervous system (45.2%, 61.7%). This result demonstrates that herbal preparations can result in ADRs similar to those of prescription medications. © 2015 Wiley Publishing Asia Pty Ltd.

    Research in the area of herbal psychopharmacology has increased markedly over the past decades. To date however, a comprehensive review of herbal antidepressant, anxiolytic and hypnotic psychopharmacology and applications in depression, anxiety and insomnia has been absent. A search of MEDLINE (PubMed), CINAHL, PsycINFO, and the Cochrane Library databases was conducted (up to February 21st 2011) on commonly used psychotropic herbal medicines. A review of the literature was conducted to ascertain mechanisms of action of these botanicals, in addition to a systematic review of controlled clinical trials for treatment of mood, anxiety and sleep disorders, which are common comorbid psychiatric disorders. Specific emphasis was given to emerging phytomedicines. Analysis of evidence levels was conducted, as were effect sizes (Cohen's d) where data were available. Results provided evidence of a range of neurochemical, endocrinological, and epigenetic effects for 21 individual phytomedicines, which are detailed in this paper. Sixty six controlled studies were located involving eleven phytomedicines. Several of these provide a high level of evidence, such as Hypericum perforatum for major depression, and Piper methysticum for anxiety disorders. Several human clinical trials provide preliminary positive evidence of antidepressant effects (Echium amoenum, Crocus sativus, and Rhodiola rosea) and anxiolytic activity (Matricaria recutita, Ginkgo biloba, Passiflora incanata, E. amoenum, and Scutellaria lateriflora). Caution should however be taken when interpreting the results as many studies have not been replicated. Several herbal medicines with in vitro and in vivo evidence are currently unexplored in human studies, and along with use of emerging genetic technologies "herbomics", are areas of potential future research.

    Diarrhea is a common dose-limiting toxicity associated with cancer chemotherapy, in particular for drugs such as irinotecan (CPT-11), 5-fluouracil, oxaliplatin, capecitabine and raltitrexed. St. John's wort (Hypericum perforatum, SJW) has anti-inflammatory activity, and our preliminary study in the rat and a pilot study in cancer patients found that treatment of SJW alleviated irinotecan-induced diarrhea. In the present study, we investigated whether SJW modulated various pro-inflammatory cytokines including interleukins (IL-1β, IL-2, IL-6), interferon (IFN-γ) and tumor necrosis factor-α (TNF-α) and intestinal epithelium apoptosis in rats. The rats were treated with irinotecan at 60 mg/kg for 4 days in combination with oral SJW or SJW-free control vehicle at 400 mg/kg for 8 days. Diarrhea, tissue damage, body weight loss, various cytokines including IL-1β, IL-2, IL-6, IFN-γ and TNF-α and intestinal epithelial apoptosis were monitored over 11 days. Our studies demonstrated that combined SJW markedly reduced CPT-11-induced diarrhea and intestinal lesions. The production of pro-inflammatory cytokines such as IL-1β, IFN-γ and TNF-α was significantly up-regulated in intestine. In the mean time, combined SJW significantly suppressed the intestinal epithelial apoptosis induced by CPT-11 over days 5-11. In particular, combination of SJW significantly inhibited the expression of TNF-α mRNA in the intestine over days 5-11. In conclusion, inhibition of pro-inflammatory cytokines and intestinal epithelium apoptosis partly explained the protective effect of SJW against the intestinal toxicities induced by irinotecan. Further studies are warranted to explore the potential for STW as an agent in combination with chemotherapeutic drugs to lower their dose-limiting toxicities

    Plants were an essential part of foraging for food and health, and for centuries remained the only medicines available to people from the remote mountain regions. Their correct botanical provenance is an essential basis for understanding the ethnic cultures, as well as for chemical identification of the novel bioactive molecules with therapeutic effects. This work describes the use of herbal medicines in the Beskid mountain ranges located south of Krakow and Lviv, two influential medieval centers of apothecary tradition in the region. Local botanical remedies shared by Boyko, Lemko, and Gorale ethnic groups were a part of the medieval European system of medicine, used according to their Dioscoridean and Galenic qualities. Within the context of ethnic plant medicine and botanical classification, this review identified strong preferences for local use of St John's-wort ( Hypericum perforatum L.), wormwood ( Artemisia absinthium L.), garlic ( Allium sativum L.), gentian ( Gentiana lutea L.), lovage ( Levisticum officinale W.D.J. Koch), and lesser periwinkle ( Vinca minor L.). While Ukrainian ethnic groups favored the use of guilder-rose ( Viburnum opulus L.) and yarrow ( Achillea millefolium L.), Polish inhabitants especially valued angelica ( Angelica archangelica L.) and carline thistle ( Carlina acaulis L.). The region also holds a strong potential for collection, cultivation, and manufacture of medicinal plants and plant-based natural specialty ingredients for the food, health and cosmetic industries, in part due to high degree of biodiversity and ecological preservation. Many of these products, including whole food nutritional supplements, will soon complement conventional medicines in prevention and treatment of diseases, while adding value to agriculture and local economies.

    To determine the efficacy and tolerance of Otikon Otic Solution (Healthy-On Ltd, Petach-Tikva, Israel), a naturopathic herbal extract (containing Allium sativum, Verbascum thapsus, Calendula flores, and Hypericum perforatum in olive oil), compared with Anaesthetic (Vitamed Pharmaceutical Ltd, Benyamina, Israel) ear drops (containing ametocaine and phenazone in glycerin) in the management of ear pain associated with acute otitis media (AOM). Children between the ages of 6 and 18 years who experienced ear pain (otalgia) and who were diagnosed with eardrum problems associated with AOM were randomly assigned to be treated with Otikon or Anaesthetic ear drops, which were instilled into the external canal(s) of the affected ear(s). Ear pain was assessed using 2 visual analog scales: a linear scale and a color scale. Pain assessment took place throughout the course of 3 days. The mean score of pain reduction was used to measure outcome. Primary pediatric community ambulatory centers. One hundred three children aged 6 to 18 years who were diagnosed with otalgia associated with AOM. Each of the 2 treatment groups were comparable on the basis of age, sex, laterality of AOM, and the effectiveness of ameliorating symptoms of otalgia. The 2 groups were also comparable to each other in the initial ear pain score and in the scores at each application of Otikon or Anaesthetic drops. There was a statistically significant improvement in ear pain score throughout the course of the study period (P =.007). Otikon, an ear drop formulation of naturopathic origin, is as effective as Anaesthetic ear drops and was proven appropriate for the management of AOM-associated ear pain.

Within the context of ethnic plant medicine and botanical classification, this review identified strong preferences for local use of St John's-wort (Hypericum perforatum L., wormwood (Artemisia absinthium L., garlic (Allium sativum L., gentian (Gentiana lutea L., lovage (Levisticum officinale W.D.J. Koch, and lesser periwinkle (Vinca minor L.. While Ukrainian ethnic groups favored the use of guilder-rose (Viburnum opulus L. and yarrow (Achillea millefolium L., Polish inhabitants especially valued angelica (Angelica archangelica L. and carline thistle (Carlina acaulis L.. The region also holds a strong potential for collection, cultivation, and manufacture of medicinal plants and plant-based natural specialty ingredients for the food, health and cosmetic industries, in part due to high degree of biodiversity and ecological preservation. Many of these products, including whole food nutritional supplements, will soon complement conventional medicines in prevention and treatment of diseases, while adding value to agriculture and local economies.

    2003-05-01

    Otitis media is 1 of the most frequent diseases of early infancy and childhood and 1 of the most common reasons for children to visit a physician. In the past 2 decades, there has been a substantial increase in the diagnosis of otitis media worldwide. In the United States, 93% of all children have had at least 1 episode of acute otitis media (AOM) by 7 years of age. Otalgia is the hallmark of AOM. Most affected children either complain of earache or manifest behavior that the parents interpret as indicating ear pain. Treatment of the ear pain early in the course of AOM decreases both parental anxiety and the child's discomfort and accelerates the healing process. The objective of this study was to determine the efficacy and tolerability of naturopathic versus traditional treatment for the management of otalgia commonly associated with AOM in children. The study was designed as a double-blind trial in an outpatient community clinic. A total of 171 children who were aged 5 to 18 years and had otalgia and clinical findings associated with middle-ear infection were studied. The children were randomly assigned to receive treatment with Naturopathic Herbal Extract Ear Drops (NHED) or anesthetic ear drops, with or without amoxicillin. On enrollment, the children were assigned by computer-numbered randomization to receive NHED (contents: allium sativum, verbascum thapsus, calendula flores, hypericum perfoliatum, lavender, and vitamin E in olive oil) 5 drops 3 times daily, alone (group A) or together with a topical anesthetic (amethocaine and phenazone in glycerin) 5 drops 3 times daily (group B), or oral amoxicillin 80 mg/kg/d (maximum 500 mg/dose) divided into 3 doses with either NHED 5 drops 3 times daily (group C) or topical anesthetic 5 drops 3 times daily (group D). A double-blind design was used, and all ear drops were placed in identical bottles. Treatment was initiated by the nurse in all cases. A single physician (M.S.) evaluated and treated all of the patients

    Multidisciplinary treatment for malignant lymphoma is reported in terms of indication, current status, and outcome of this approach to Hodgkin's disease (HD) and non-Hodgkin's lymphomas (NLH). HD is considered to be most successfully managed with multidisciplinary treatment. Success of treatment of HD in European countries and the US, which has resulted from accurate staging of HD and developments in radiotherapy and chemotherapy, is reviewed in the literature. Problems in the treatment of HD in Japan are presented. A treatment policy for NHL is discussed according to the original site, i.e. lymph nodes, Waldeyer's ring or other sites of tumor involvement.

    Full Text Available The study aimed to determine the effect of aqueous extracts of medicinal plants (Matricaria chamomilla, Hypericum perforatum, Achillea millefolium, and Urtica dioica containing allelopathic compounds on seed germination in lambsquarters (Chenopodium album and herbicide-resistant windgrass (Apera spica-venti. A Petri-dish experiment was carried out, in which the effects of five concentrations of aqueous extracts on the germination of weeds were assessed for 10 consecutive days. It was found that the dynamics of seed germination are closely related to the type and concentration of aqueous extract of medicinal plants. The 8% U. dioica aqueous extract posed the strongest inhibitory effect, limiting the germination of both lambsquarters and windgrass. Additionally, weed germination was delayed by 12–72 h in the presence of extracts, compared with the control. Summing up, the aqueous extracts of medicinal plants, especially their higher concentrations, pose a desirable inhibiting effect against the germination of lambsquarters and herbicide-resistant windgrass seeds.

    Drugs of plant origin such as Arnica montana, Calendula officinalis or Hypericum perforatum have been frequently used to promote wound healing. While their effect on wound healing using preparations at pharmacological concentrations was supported by several in vitro and clinical studies, investigations of herbal homeopathic remedies on wound healing process are rare. The objective of this study was to investigate the effect of a commercial low potency homeopathic remedy Similasan® Arnica plus Spray on wound closure in a controlled, blind trial in vitro. We investigated the effect of an ethanolic preparation composed of equal parts of Arnica montana 4x, Calendula officinalis 4x, Hypericum perforatum 4x and Symphytum officinale 6x (0712-2), its succussed hydroalcoholic solvent (0712-1) and unsuccussed solvent (0712-3) on NIH 3T3 fibroblasts. Cell viability was determined by WST-1 assay, cell growth using BrdU uptake, cell migration by chemotaxis assay and wound closure by CytoSelect ™Wound Healing Assay Kit which generated a defined "wound field". All assays were performed in three independent controlled experiments. None of the three substances affected cell viability and none showed a stimulating effect on cell proliferation. Preparation (0712-2) exerted a stimulating effect on fibroblast migration (31.9%) vs 14.7% with succussed solvent (0712-1) at 1:100 dilutions (p 0.05). Preparation (0712-2) at a dilution of 1:100 promoted in vitro wound closure by 59.5% and differed significantly (p < 0.001) from succussed solvent (0712-1), which caused 22.1% wound closure. Results of this study showed that the low potency homeopathic remedy (0712-2) exerted in vitro wound closure potential in NIH 3T3 fibroblasts. This effect resulted from stimulation of fibroblasts motility rather than of their mitosis.

    A precondition for the successful treatment of headaches is the correct headache diagnosis. Triptans are effective for attack treatment of migraine and cluster headache. However, there are not effective for the treatment of tension-type headache. For the prevention of frequent episodic migraine betablockers, flunarizine, topiramate and amitriptyline are recommended. For the prevention of chronic migraine evidence is only available for onabotulinumtoxinA and topiramate. For prophylactic treatment of tension-type headaches tricyclic antidepressants are used. In cluster headache verapamil (in combination with steroids) is the most frequently used prophylactic agent. This article focusses on the current acute and prophylactic treatment of common headache syndromes. © Georg Thieme Verlag KG Stuttgart · New York.

    In the treatment of wastes, such as liquid radioactive effluents, it is known to remove radionuclides by successive in situ precipitation of cobalt sulphide, an hydroxide, barium sulphate and a transition element ferrocyanide, followed by separation of the thereby decontaminated effluent. In this invention, use is made of precipitates such as obtained above in the treatment of further fresh liquid radioactive effluent, when it is found that the precipitates have additional capacity for extracting radionuclides. The resulting supernatant liquor may then be subjected to a further precipitation treatment such as above. Decontamination factors for radionuclides of Ce, Ru, Sr and Cs have been considerably enhanced. (author)

    With this study, we aimed to document traditional uses of medicinal plants in the western part of Aladaglar/Nigde. This study was conducted between 2003 and 2005. The research area was in the western part of the Aladaglar mountains. The settlements in Aladaglar (5 towns and 10 villages) were visited during the field work. The plants collected by the help of medicinal plant users. The plants were identified and voucher specimens prepared. These voucher specimens were kept at the Herbarium of Istanbul University Faculty of Pharmacy (ISTE). We collected the information by means of semi-structured interviews with 170 informants (90 men and 80 women). In addition, the relative importance value of the species was determined and the informant consensus factor (FIC) was calculated for the medicinal plants researched in the study. According to the results of the identification, among 126 plants were used by the inhabitants and 110 species belonging to 40 families were used for medicinal purposes. Most of the medicinal plants used in Aladaglar/Nigde belong to the families Lamiaceae (25 species), Asteraceae (16 species), Apiaceae (7 species), Fabaceae (6 species) and Brassicaceae (5 species). The most commonly used plant species were Hypericum perforatumThymus sipyleus var. sipyleus, Rosa canina, Urtica dioica, Malva neglecta, Thymus leucotrichus, Salix alba, Mentha longifolia, Berberis crataegina, Juniperus oxycedrus, Viscum album subsp. abietis, Allium rotundum and Taraxacum stevenii. The most common preparations were infusion and decoction. The traditional medicinal plants have been mostly used for the treatment of cardiovascular diseases (86%), hemorrhoids (79%), urinary diseases (69%), diabetes (68%) and respiratory diseases (61%). The use of traditional medicine was still widespread among the inhabitants of Aladaglar mountains/Nigde region. Due to the lack of medical facilities in the villages of Aladaglar mountains, local people prefer herbal treatment rather than

    Bayliak Maria M.

    2016-01-01

    Full Text Available Background: We studied in vitro and vivo antioxidant and prooxidant abilities of aqueous extracts from Rosa canina L., Rhodiola rosea L., Hypericum perforatum L., and Gentiana lutea L. Methodology: Total antioxidant capacity was measured by four assays (phosphomolybdate method, Fe3+-reducing activity, ABTS•+ scavenging, H2O2 scavenging. Prooxidant activity was estimated by H2O2 production. Yeast viability in the presence of H2O2 and/or plant extracts was determined by plating or by counting live cells’ number. Results: Plant extracts differed in the total phenolic content (R. canina > R. rosea > H. perforatum > G. lutea which clearly correlated with their ABTS•+ scavenging activity (R2 = 0.963. H2O2 scavenging activity was not clearly associated with plant phenol levels and was significantly higher in acidic, than in alkaline medium. In line with this, plant extracts effectively protected yeast S. cereviasiae against H2O2 and stimulated reproductive ability of yeast cells at acidic but not at alkaline pH. At alkaline pH, plant extracts produced certain amounts of H2O2 which were related to their phenolic content. Conclusion: The antioxidant activity of plant extracts is decreased at alkaline pH with an increase in the prooxidant activity. It reduces protective capacity of plant extracts against oxidative and other stresses in vivo.

    Full Text Available Quality of life on Earth in the future will largely depend on the amount of safe water. As the most fundamental source of life, water is relentlessly consumed and polluted. To halt this trend, many countries are taking extensive measures and investing substantial resources in order to stop the contamination of water and return at least tolerably good water quality to nature. The goal of water purification is to obtain clean water with the sewage sludge as a by-product. Clean water is returned to nature, and further treatment of sludge may be subject to other procedures. The conclusion of this paper is simple. The procedure with purified water is easily achievable, purified water is discharged into rivers, lakes and seas, but the problem of further treatment of sludge remains. This paper presents the basic methods of wastewater treatment and procedures for processing the products from contaminated water. The paper can serve as a basis for further elaboration. Water Pollution In order to ensure normal life of living creatures, the water in which they live or the water they use must have a natural chemical composition and natural features. When, as a result of human activities, the chemical composition of water and the ratio of its chemical elements significantly change, we say that water is polluted. When the pollutants come from industrial plants, we are talking about industrial wastewater, and when they come from households and urban areas, we are talking about municipal wastewater. Both contain a huge amount of pollutants that eventually end up in rivers. Then, thousands of defenseless birds, fish and other animals suffer, and environmental consequences become immeasurable. In addition, the waste fed to the water often ends up in the bodies of marine animals, so they can return to us as food. Thermal water pollution also has multiple effects on the changes in the wildlife composition of aquatic ecosystems. Polluted water can be purified by

    In this work we intend to verify the applicability of a computational methodology to predict structural features of organic compounds with biological activity. We selected three phloroglucinols and compared their calculated conformational data with their X-ray crystallographic structure. The results showed that conformations obtained by conformational analysis with the AM1 method followed by geometry optimization by using the DFT B3LYP/6-31 G(d,p) basis set are in very good agreement with X-ray data, indicating that the methodology employed here seems to be a very useful tool in order to predict the conformational preference for this class of compounds.

    2016-10-01

    The present study was aimed to evaluate the effect of Urtica dioica (UD) extract against chronic unpredictable stress (CUS)-induced associative memory dysfunction and attempted to explore the possible mechanism. Male Swiss albino mice (25-30g) were divided into six groups, viz. group-I received 0.3% carboxymethyl cellulose and served as control (CTRL), group II was exposed to CUS (21days) and received vehicle (CUS), group III was subjected to CUS and received Hypericum perforatum extract (350mg/kg, p.o.) (CUS+HYP), group IV received Hypericum perforatum extract (350mg/kg, p.o.) (CTRL+HYP); group V was subjected to CUS and received UD extract (50mg/kg, p.o.) (CUS+UD), group VI received UD extract (50mg/kg, p.o.) (CTRL+UD). CUS significantly induced body weight loss (p<0.05) and associative memory impairment in step down task (p<0.05) as compared to control mice. CUS significantly downregulated Smo (p<0.05), Gli1 (p<0.01), cyclin D1 (p<0.05), BDNF (p<0.01), TrKB (p<0.01) and MAPK1 (p<0.01) mRNA expression in hippocampus as compared to control mice. CUS significantly increased the levels of TBARS (p<0.01) and nitric oxide (p<0.001), and decreased catalase (p<0.001) and total thiol (p<0.01) in plasma resulting in oxidative stress and inflammation. Chronic UD administration significantly reverted CUS mediated body weight loss (p<0.05) and cognitive impairment (p<0.05). UD administration significantly decreased the levels of TBARS (p<0.01) and nitric oxide (p<0.05), and increased the levels of catalase (p<0.01) and total thiol (p<0.05) in plasma. Chronic UD administration significantly upregulated hippocampal Smo (p<0.05), Gli1 (p<0.001), cyclin D1 (p<0.05), BDNF (p<0.05), TrKB (p<0.05) and MAPK1 (p<0.05) in stressed mice. Further, UD extract did not reverse cyclopamine induced downregulation of Gli1 and Ptch1 mRNA in hippocampal slices. UD modulated Smo-Gli1 pathway in the hippocampus as well as exerted anti-inflammatory and antioxidant effects. UD extract might prove

  8. Hyperforin inhibits vesicular uptake of monoamines by dissipating pH gradient across synaptic vesicle membrane.

    Science.gov (United States)

    Roz, Netta; Rehavi, Moshe

    2003-06-13

    Extracts of Hypericum perforatum (St. John's wort) have antidepressant properties in depressed patients and exert antidepressant-like action in laboratory animals. The phloroglucinol derivative hyperforin has become a topic of interest, as this Hypericum component is a potent inhibitor of monoamines reuptake. The molecular mechanism by which hyperforin inhibits monoamines uptake is yet unclear. In the present study we try to clarify the mechanism by which hyperforin inhibits the synaptic vesicle transport of monoamines. The pH gradient across the synaptic vesicle membrane, induced by vacuolar type H(+)-ATPase, is the major driving force for vesicular monoamines uptake and storage. We suggest that hyperforin, like the protonophore FCCP, dissipates an existing Delta pH generated by an efflux of inwardly pumped protons. Proton transport was measured by acridine orange fluorescence quenching. Adding Mg-ATP to a medium containing 130 mM KCl and synaptic vesicles caused an immediate decrease in fluorescence of acridine orange and the addition of 1 microM FCCP abolished this effect. H(+)-ATPase dependent proton pumping was inhibited by hyperforin in a dose dependent manner (IC(50) = 1.9 x 10(-7) M). Hyperforin acted similarly to the protonophore FCCP, abolishing the ATP induced fluorescence quenching (IC(50) = 4.3 x 10(-7) M). Hyperforin and FCCP had similar potencies for inhibiting rat brain synaptosomal uptake of [3H]monoamines as well as vesicular monoamine uptake. The efflux of [3H]5HT from synaptic vesicles was sensitive to both drugs, thus 50% of preloaded [3H]5HT was released in the presence of 2.1 x 10(-7) M FCCP and 4 x 10(-7) M hyperforin. The effect of hyperforin on the pH gradient in synaptic vesicle membrane may explain its inhibitory effect on monoamines uptake, but could only partially explain its antidepressant properties.

    Resistances to herbal medicines are still not defined and finding natural remedies against drug resistant Mycobacterium tuberculosis (MTB) has research priority. The antimycobacterial susceptibility method for herbal extracts is unclearly defined and there is no standard method for assessment of the materials against bacteria. In the present study, time kill of three medicinal plants was determined against MTB. The clinical isolate of MTB from a patient who harbored confirmed tuberculosis was used in the study. Aqueous extracts of Aloe vera leaves, mint, and Hypericum perforatum were prepared using reflux distillation. Disk diffusion methods were conducted in Petri dishes and McCartney bottles containing Löwenstein-Jensen medium to measure the sensitivity of plant extracts in serial concentrations of 0.25-8mg/mL. A pour plate method was performed by mixing 0.7mL of each concentration of extract in 5mL Löwenstein-Jensen medium followed by surface culturing of MTB fresh cells. The time kill method was conducted by bacterial suspension in equal amounts of the extract and viable evaluation in fresh culture at the beginning, and at 24-h, 48-h, 72-h, and 1-week intervals. All cultures were incubated at 37°C for 4weeks. Inoculum concentrations were considered as a variable. The zones of inhibition of A. vera, H. perforatum, and mint extracts in the disk diffusion method in McCartney bottles were 60mm, 41mm, and zero, respectively, but Petri dishes did not have repeatable results. In the pour plate method, an extract concentration up to 1mg/mL could inhibit cell growth. In mint extract, colony forming was four times more than the others at 0.5mg/mL. Time kill of 95% of cells occurred when exposed to extracts of A. vera and H. perforatum separately, but was 50% in 24 h and 20% in 10 min. The time kill for mint was 95% in 1week. The results give some scientific basis to the use of plant extracts for growth control of MTB cells. Clinical trials are recommended for

  5. Treatment of Epileptic Encephalopathies.

    Science.gov (United States)

    Balestrini, Simona; Sisodiya, Sanjay M

    2017-01-01

    Epileptic encephalopathies represent the most severe epilepsies, with onset in infancy and childhood and seizures continuing in adulthood in most cases. New genetic causes are being identified at a rapid rate. Treatment is challenging and the overall outcome remains poor. Available targeted treatments, based on the precision medicine approach, are currently few. To provide an overview of the treatment of epileptic encephalopathies with known genetic determinants, including established treatment, anecdotal reports of specific treatment, and potential tailored precision medicine strategies. Genes known to be associated to epileptic encephalopathy were selected. Genes where the association was uncertain or with no reports of details on treatment, were not included. Although some of the genes included are associated with multiple epilepsy phenotypes or other organ involvement, we have mainly focused on the epileptic encephalopathies and their antiepileptic treatments. Most epileptic encephalopathies show genotypic and phenotypic heterogeneity. The treatment of seizures is difficult in most cases. The available evidence may provide some guidance for treatment: for example, ACTH seems to be effective in controlling infantile spams in a number of genetic epileptic encephalopathies. There are potentially effective tailored precision medicine strategies available for some of the encephalopathies, and therapies with currently unexplained effectiveness in others. Understanding the effect of the mutation is crucial for targeted treatment. There is a broad range of disease mechanisms underlying epileptic encephalopathies, and this makes the application of targeted treatments challenging. However, there is evidence that tailored treatment could significantly improve epilepsy treatment and prognosis.

    Full Text Available Childhood constipation is ofton a long_term problem requiring treatment over months or years. There is no single treatment metod for constipation and many children do not respond and continue to have chronic problems. Treatment is consisted of: Disimpaction,Drug adminstration , Diet modilation, and behaverial therapy. It is necessary in all cases that not responding to conventional therapy, un diagnosed organic causes, non proper drug, short course therapy, behaverial disorder and withholding should be considered. Internal anal achalasia, Neural tube defect, Neurointestinal dysplasia. and food allergy are the most important predisposing factors in treatment failer . PEG is drug of choice for treatment and therapy must be continued for several months or years. Psycologic consulting should be considered in patients with severe behaverial disorder.   Key words: Children, Functional Constipation, Treatment.

  7. Hyperthermia treatment planning

    2000-01-01

    The development of hyperthermia, the treatment of tumours with elevated temperatures in the range of 40-44 deg. C with treatment times over 30 min, greatly benefits from the development of hyperthermia treatment planning. This review briefly describes the state of the art in hyperthermia technology, followed by an overview of the developments in hyperthermia treatment planning. It particularly highlights the significant problems encountered with heating realistic tissue volumes and shows how treatment planning can help in designing better heating technology. Hyperthermia treatment planning will ultimately provide information about the actual temperature distributions obtained and thus the tumour control probabilities to be expected. This will improve our understanding of the present clinical results of thermoradiotherapy and thermochemotherapy, and will greatly help both in optimizing clinical heating technology and in designing optimal clinical trials.

    Full Text Available Equal treatment of shareholders is regulated in Art.269 of Company Act (2011 of Republic of Serbia. Equal treatment of shareholders means that all shareholders are to be treated equally under same circumstances. Obligation to treat all shareholders equally rests on all company bodies, predominantly general meeting. The standard whether an action violates the principle of equal treatment of all shareholders regarding the main rights of shareholders (such as voting right etc. is the nominal value of shares, or the equal treatment per person regarding ancillary rights (such as right to speak in shareholders' meeting etc.. Any action deviating from this standard is unlawful if the unequal treatment is not justified on the facts. If the principle of equal treatment is violated by general meeting resolution, such resolution may be annulled by the court.

    2017-09-01

    decline was 18.16% at 100 ppm Cd and was 24.55% at 1500 ppm Pb compared to the control. At the second harvest, fresh weight declined by 15.24% and 32.72% compared to the control at 100 ppm cadmium and 1500 ppm lead, respectively. At the highest concentrations of Cd and Pb, dry weight of peppermint was dropped 22.92% and 25.88% at the first harvest. For the second harvest, decreased dry weights were 39.01% and 26.77% compared to the control, respectively. Stancheva et al (2010 revealed that increasing cadmium and lead concentrations caused to the shoot and root weights of sage (salvia officinalis L. declined by 15 and 10%, respectively. They mentioned the glutathione-ascorbate cycle plays a vital role in neutralizing the destructive effects of ROS in sage. In this cycle, guaiacol peroxidase, ascorbate peroxidase and catalase enzymes increase and lead to diminish the ROS activity. In the same doses of cadmium and lead (100 ppm, cadmium had a more reductive effects than lead for all traits except for essential oil at the first harvest. This event is due to more toxicity of cadmium compared to lead. The toxicity threshold of cadmium and lead was reported 5 and 30 mg kg-1. Tirillini et al., (2006 reported that hypericin content in essential oil of hypericum perforatum L. was not affected by chrome stress. Conclusion Essential oil, fresh and dry weight of peppermint did not show any significant change when the concentrations of cd and pb were maximum, so it seems that peppermint can be cultivated in polluted water or soil with cadmium and lead.

    1999-12-01

    Promising cognitive-behavioral and medication treatments for hypochondriasis are in the early stages of evaluation. Little is known about the treatment preferences and opinions of individuals seeking help for this problem. In this exploratory study, 23 volunteers from the community with a DSM-IV diagnosis of hypochondriasis were recruited through a newspaper advertisement. Participants were presented with a survey which included balanced descriptions of both a medication and a cognitive-behavioral treatment for intense illness concerns (hypochondriasis). The brief descriptions of the treatments discussed the time commitment required as well as the major advantages and disadvantages of each. Results showed that, relative to medication treatment, cognitive-behavioral treatment was predicted to be more effective in both the short and long terms and was rated as more acceptable. Psychological treatment was indicated as the first choice by 74% of respondents, medication by 4%, and 22% indicated an equal preference. Forty-eight percent of respondents would only accept the psychological treatment.

    2014-12-01

    Alopecia is a common concern encountered in the medical practice. Treatment approach varies according to the type and severity of alopecia. However, available treatment options have limited efficacy and several adverse effects. Presently, there are different treatment options being studied to overcome these limitations. Additionally, cellular pathways involved in the pathophysiology of alopecia are further being clarified to potentially target pathogenic molecules. We searched the literature for recently published articles discussing new treatment options as well as mechanisms involved in alopecia. We discuss the use of stem cells, growth factors, cellular pathways and robotic hair transplant, among other emerging therapies used for alopecia. Future looks very promising and new effective treatments such as janus kinase inhibitors could possibly be available for alopecia areata. The stem-cell technology is advancing and companies involved in hair follicle neogenesis are starting clinical trials on patients with androgenetic alopecia.

  14. Nonpharmacological treatment of epilepsy

    Directory of Open Access Journals (Sweden)

    2011-01-01

    Full Text Available Nonpharmacological treatment of epilepsy includes surgery, vagal nerve stimulation, ketogenic diet, and other alternative/complementary therapies, e.g., yoga, Ayurveda, electroencephalography (EEG biofeedback technique, aerobic exercise, music therapy, transcranial magnetic stimulation, acupuncture, and herbal remedies (traditional Chinese medicine. Alternative therapies, despite the term, should not be considered as an alternative to antiepileptic medication; they complement accepted drug treatment. Alternative therapies like yoga, through techniques that relax the body and mind, reduce stress, improve seizure control, and also improve quality of life. Ketogenic diet is a safe and effective treatment for intractable epilepsies; it has been recommended since 1921. The diet induces ketosis, which may control seizures. The most successful treatment of epilepsy is with modern antiepileptic drugs, which can achieve control of seizures in 70-80% cases. Patients opt for alternative therapies because they may be dissatisfied with antiepileptic drugs due to their unpleasant side effects, the long duration of treatment, failure to achieve control of seizures, cultural beliefs and, in the case of women, because they wish to get pregnant Surgical treatment may lead to physical and psychological sequelae and is an option only for a minority of patients. This article presents supportive evidence from randomized controlled trials done to assess the benefit of non-pharmacological treatment.

    The history of the development of generic phytosanitary irradiation (PI) treatments is discussed beginning with its initial proposal in 1986. Generic PI treatments in use today are 150 Gy for all hosts of Tephritidae, 250 Gy for all arthropods on mango and papaya shipped from Australia to New Zealand, 300 Gy for all arthropods on mango shipped from Australia to Malaysia, 350 Gy for all arthropods on lychee shipped from Australia to New Zealand and 400 Gy for all hosts of insects other than pupae and adult Lepidoptera shipped to the United States. Efforts to develop additional generic PI treatments and reduce the dose for the 400 Gy treatment are ongoing with a broad based 5-year, 12-nation cooperative research project coordinated by the joint Food and Agricultural Organization/International Atomic Energy Agency Program on Nuclear Techniques in Food and Agriculture. Key groups identified for further development of generic PI treatments are Lepidoptera (eggs and larvae), mealybugs and scale insects. A dose of 250 Gy may suffice for these three groups plus others, such as thrips, weevils and whiteflies. - Highlights: ► The history of phytosanitary irradiation (PI) treatments is given. ► Generic PI treatments in use today are discussed. ► Suggestions for future research are presented. ► A dose of 250 Gy for most insects may suffice.

    Martonffy, Andrea Ildiko

    2015-01-01

    Improper tooth alignment due to crowding, malocclusion, and missing teeth can cause difficulties with eating and speech, and premature wear. It is estimated that more than 20% of children would benefit from orthodontic treatment to correct these conditions, many of which will persist into adulthood if not corrected. Orthodontic care is gaining popularity among adults for similar concerns, as well as for correction of cosmetic issues. The psychological effects of malocclusion should not be ignored. The American Association of Orthodontists recommends that all children undergo evaluation at the first recognition of an orthodontic condition and no later than age 7 years. Some children will need early treatment to help eliminate developing conditions and improve the foundations of the bite, which can ease later treatment in adolescence. For others, treatment in adolescence without early treatment is recommended. Standard cemented braces or clear, removable aligners may be used, depending on the patient's corrective needs. Average treatment time is approximately 2 years; this may be shortened by the use of accelerative techniques. Routine preventive dental care should be continued during the treatment period.

    2007-11-01

    Selective mutism is a communication disorder of childhood in which the child does not speak in specific social situations despite the ability to speak in other situations. A literature review was completed in order to provide practical guidelines for the assessment and treatment of children with selective mutism. There are many different behavioral approaches in the treatment of this disorder, e.g. contingency management, shaping, stimulus fading, escape-avoidance, self-modeling, learning theory approaches. A clearer diagnostic understanding of the disorder as part of anxiety or oppositional disorders needs to be realized prior to generalize an effective treatment for this disorder.

    Telangiectasia is dilatation of the subpapillary venous plexus of the epidermis of the lower limbs, which can lead to aesthetic embarrassment. Before treating telangiectasia, patient history and clinical examination help establishing its origin. It can be with isolated, associated reticular drainage veins, or be part of superficial venous insufficiency. Several types of treatment have been proposed. Microsclerotherapy is the most effective and least costly. Muller's phlebectomy can be performed when telangiectasia is fed by large reticular veins, either afferent or efferent. Treatment by laser and pulsed light appear best reserved to treatment of finer venous dilatations, either complementary or after failure of sclerotherapy.

    1983-01-01

    Some types of pneumoconiosis, such as asbestosis, are characterized by marked restrictive functional patterns. Treatment is begun when definite arterial hypoxemia appears, since the inhalation of oxygen clearly lowers pulmonary artery pressure. It is also important that the onset of concomitant airway obstruction is recognized promptly. From the sociomedical standpoint the most significant pneumoconiosis continues to be the miner's anthracosilicosis. The functional pattern of this pneumoconiosis is clearly airway obstruction, and such anthracosilicotic airway obstruction responds like all other forms of airway obstruction to antiobstructive therapy. The fundamentals of this therapy, which is based on the use of bronchodilators, adrenal cortical hormones and antibiotics, are described.

    Concurrent use of herbs may mimic, magnify, or oppose the effect of drugs. Plausible cases of herb-drug interactions include: bleeding when warfarin is combined with ginkgo (Ginkgo biloba), garlic (Allium sativum), dong quai (Angelica sinensis), or danshen (Salvia miltiorrhiza); mild serotonin syndrome in patients who mix St John's wort (Hypericum perforatum) with serotonin-reuptake inhibitors; decreased bioavailability of digoxin, theophylline, cyclosporin, and phenprocoumon when these drugs are combined with St John's wort; induction of mania in depressed patients who mix antidepressants and Panax ginseng; exacerbation of extrapyramidal effects with neuroleptic drugs and betel nut (Areca catechu); increased risk of hypertension when tricyclic antidepressants are combined with yohimbine (Pausinystalia yohimbe); potentiation of oral and topical corticosteroids by liquorice (Glycyrrhiza glabra); decreased blood concentrations of prednisolone when taken with the Chinese herbal product xaio chai hu tang (sho-salko-to); and decreased concentrations of phenytoin when combined with the Ayurvedic syrup shankhapushpi. Anthranoid-containing plants (including senna [Cassia senna] and cascara [Rhamnus purshiana]) and soluble fibres (including guar gum and psyllium) can decrease the absorption of drugs. Many reports of herb-drug interactions are sketchy and lack laboratory analysis of suspect preparations. Health-care practitioners should caution patients against mixing herbs and pharmaceutical drugs.

  1. Pharmacokinetic Interactions between Drugs and Botanical Dietary Supplements.

    Sprouse, Alyssa A; van Breemen, Richard B

    2016-02-01

    The use of botanical dietary supplements has grown steadily over the last 20 years despite incomplete information regarding active constituents, mechanisms of action, efficacy, and safety. An important but underinvestigated safety concern is the potential for popular botanical dietary supplements to interfere with the absorption, transport, and/or metabolism of pharmaceutical agents. Clinical trials of drug-botanical interactions are the gold standard and are usually carried out only when indicated by unexpected consumer side effects or, preferably, by predictive preclinical studies. For example, phase 1 clinical trials have confirmed preclinical studies and clinical case reports that St. John's wort (Hypericum perforatum) induces CYP3A4/CYP3A5. However, clinical studies of most botanicals that were predicted to interact with drugs have shown no clinically significant effects. For example, clinical trials did not substantiate preclinical predictions that milk thistle (Silybum marianum) would inhibit CYP1A2, CYP2C9, CYP2D6, CYP2E1, and/or CYP3A4. Here, we highlight discrepancies between preclinical and clinical data concerning drug-botanical interactions and critically evaluate why some preclinical models perform better than others in predicting the potential for drug-botanical interactions. Gaps in knowledge are also highlighted for the potential of some popular botanical dietary supplements to interact with therapeutic agents with respect to absorption, transport, and metabolism.

    St. John's wort (SJW, Hypericum perforatum) is one of the popular nutraceuticals for treating depression. Methotrexate (MTX) is an immunosuppressant with narrow therapeutic window. This study investigated the effect of SJW on MTX pharmacokinetics in rats. Rats were orally given MTX alone and coadministered with 300 and 150 mg/kg of SJW, and 25 mg/kg of diclofenac, respectively. Blood was withdrawn at specific time points and serum MTX concentrations were assayed by a specific monoclonal fluorescence polarization immunoassay method. The results showed that 300 mg/kg of SJW significantly increased the AUC 0−t and C max of MTX by 163% and 60%, respectively, and 150 mg/kg of SJW significantly increased the AUC 0−t of MTX by 55%. In addition, diclofenac enhanced the C max of MTX by 110%. The mortality of rats treated with SJW was higher than that of controls. In conclusion, coadministration of SJW significantly increased the systemic exposure and toxicity of MTX. The combined use of MTX with SJW would need to be with caution. -- Highlights: ► St. John's wort significantly increased the AUC 0−t and C max of methotrexate. ► Coadministration of St. John's wort increased the exposure and toxicity of methotrexate. ► The combined use of methotrexate with St. John's wort will need to be with caution.

    We have labelled hypericin, a polyphenolic polycyclic quinone found in St. John's wort (Hypericum perforatum), with 123 I and evaluated mono-[ 123 I]iodohypericin (MIH) as a potential necrosis-avid diagnostic tracer agent. MIH was prepared by an electrophilic radioiodination method. The new tracer agent was evaluated in animal models of liver infarction in the rat and heart infarction in the rabbit using single-photon emission computed tomography (SPECT), triphenyltetrazolium chloride (TTC) histochemical staining, serial sectional autoradiography and microscopy, and radioactivity counting techniques. Using in vivo SPECT imaging, hepatic and cardiac infarctions were persistently visualised as well-defined hot spots over 48 h. Preferential uptake of the tracer agent in necrotic tissue was confirmed by perfect match of images from post-mortem TTC staining, autoradiography (ARX) and histology. Radioactivity concentration in infarcted tissues was over 10 times (liver; 3.51% ID/g in necrotic tissue vs 0.38% ID/g in normal tissue at 60 h p.i.) and over 6 times (myocardium; 0.36% ID/g in necrotic tissue vs 0.054% ID/g in normal tissue; ratios up to 18 for selected parts on ARX images) higher than in normal tissues. The results suggest that hypericin derivatives may serve as powerful necrosis-avid diagnostic agents for assessment of tissue viability. (orig.)

    We have labelled hypericin, a polyphenolic polycyclic quinone found in St. John's wort (Hypericum perforatum), with{sup 123}I and evaluated mono-[{sup 123}I]iodohypericin (MIH) as a potential necrosis-avid diagnostic tracer agent. MIH was prepared by an electrophilic radioiodination method. The new tracer agent was evaluated in animal models of liver infarction in the rat and heart infarction in the rabbit using single-photon emission computed tomography (SPECT), triphenyltetrazolium chloride (TTC) histochemical staining, serial sectional autoradiography and microscopy, and radioactivity counting techniques. Using in vivo SPECT imaging, hepatic and cardiac infarctions were persistently visualised as well-defined hot spots over 48 h. Preferential uptake of the tracer agent in necrotic tissue was confirmed by perfect match of images from post-mortem TTC staining, autoradiography (ARX) and histology. Radioactivity concentration in infarcted tissues was over 10 times (liver; 3.51% ID/g in necrotic tissue vs 0.38% ID/g in normal tissue at 60 h p.i.) and over 6 times (myocardium; 0.36% ID/g in necrotic tissue vs 0.054% ID/g in normal tissue; ratios up to 18 for selected parts on ARX images) higher than in normal tissues. The results suggest that hypericin derivatives may serve as powerful necrosis-avid diagnostic agents for assessment of tissue viability. (orig.)

    Full Text Available Eriophyid-myte kom waarskynlik op die meeste hoër plante voor en is oor die algemeen baie gasheerspesifiek. Sommiges is skadelik genoeg om oorweeg te word vir biologiese beheerprogramme teen ongewenste plante. Algemene belangstelling in die gebruik van eriophyids vir onkruidbeheer het onlangs ontstaan en vyf spesies is reeds, meestal suksesvol, gebruik vir onkruidbeheer in ander lande. Eriophyid-myte is nog nie as onkruidbeheeragente in Suid-Afrika benut nie. Sewentien spesies wat simptome veroorsaak wat moontlik nuttig kan wees vir die beheer van 12 plantspesies, wat as onkruide in Suid-Afrika beskou word, word gelys en bespreek.

    Flavonoids are important active ingredients in many traditional Chinese medicines. In this paper, capillary electrophoresis with amperometric detection was employed to separate and detect eight flavonoids, rutin, quercetrin, quercetin, kaempferol, kaempferide, catechin, apigenin, and luteolin, in a home-made capillary electrophoresis device. Under the separation voltage of 2000 V, the eight flavonoids could be completely separated within 33 min in 18 mM borax running buffer at pH 10.2. Good linear relationships were obtained for all analytes and the detection limits for flavonoids ranged from 0.46 to 0.85 μM. Then, the method was applied to separate and determine the flavonoids in three traditional Chinese medicines, hippophae rhamnoides, hypericum perforatum, and cacumen platycladi. Finally, rutin, kaempferol, quercetin, and quercetrin were discovered in these medicines and the concentrations ranged from 0.28 to 9.94 mg/g. The recoveries of flavonoids ranged from 84.7 to 113%, which showed the high reliability of this method. © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    Tinctures are widely used liquid pharmaceutical preparations traditionally obtained by maceration of one or more medicinal plants in ethanol-water solutions. Such a process results in the extraction of virtually hundreds of structurally diverse compounds with different polarities. Owing to the large chemical diversity of the constituents present in the herbal tinctures, the analytical tools used for the quality control of tinctures are usually optimised only for the detection of single chemical entities or specific class of compounds. In order to overcome the major limitations of the current methods used for analysis of tinctures, a new methodological approach based on NMR spectroscopy and MS spectrometry has been tested with different commercial tinctures. Diffusion-edited 1H-NMR (1D DOSY) and 1H-NMR with suppression of the ethanol and water signals have been applied here for the first time to the direct analysis of commercial herbal tinctures derived from Echinacea purpurea, Hypericum perforatum, Ginkgo biloba and Valeriana officinalis. The direct injection of the tinctures in the MS detector in order to obtain the corresponding metabolic profiles was also performed. Using both NMR and MS methods it was possible, without evaporation or separation steps, to obtain a metabolic fingerprint able to distinguish between tinctures prepared with different plants. Batch-to-batch homogeneity, as well as degradation after the expiry date of a batch, was also investigated. The techniques proposed here represent fast and convenient direct analyses of medicinal herbal tinctures.

    Polycystic ovary syndrome (PCOS) is a common, complex reproductive endocrinopathy characterized by menstrual irregularities, hyperandrogenism and polycystic ovaries. Lifestyle modification is a first‐line intervention; however, there are barriers to success for this form of self‐care, and women often seek adjunct therapies including herbal medicines. This pragmatic, randomized controlled trial, delivered in communities of Australia in overweight women with PCOS, compared the effectiveness and safety of a lifestyle intervention plus herbal medicine against lifestyle alone. All participants were helped to construct a personalized lifestyle plan. The herbal intervention consisted of two tablets. Tablet 1 contained Cinnamomum verum, Glycyrrhiza glabra, Hypericum perforatum and Paeonia lactiflora. Tablet 2 contained Tribulus terrestris. The primary outcome was oligomenorrhoea/amenorrhoea. Secondary outcomes were hormones; anthropometry; quality of life; depression, anxiety and stress; pregnancy; birth outcomes; and safety. One hundred and twenty‐two women gave their consent. At 3 months, women in the combination group recorded a reduction in oligomenorrhoea of 32.9% (95% confidence interval 23.3–42.6, p herbal medicines in women with PCOS. © 2017 The Authors.

    Full Text Available There are a number of compounds that can modify the activity of ABC (ATP-binding cassette and SLC (solute carrier transporters in the blood-brain barrier (BBB. The aim of this study was to investigate the effect of natural and synthetic substances on the expression level of genes encoding transporters present in the BBB (mdr1a, mdr1b, mrp1, mrp2, oatp1a4, oatp1a5 and oatp1c1. Our results showed that verapamil caused the greatest reduction in the mRNA level while other synthetic (piracetam, phenobarbital and natural (codeine, cyclosporine A, quercetin substances showed a selective inhibitory effect. Further, the extract from the roots of Panax ginseng C. A. Meyer exhibited a decrease of transcription against selected transporters whereas the extract from Ginkgo biloba L. leaves resulted in an increase of the expression level of tested genes, except for mrp2. Extract from the aerial parts of Hypericum perforatum L. was the only one to cause an increased mRNA level for mdr1 and oatp1c1. These findings suggest that herbs can play an important role in overcoming the BBB and multidrug resistance to pharmacotherapy of brain cancer and mental disorders, based on the activity of selected drug-metabolizing enzymes and transporters located in the BBB

    2011-01-01

    Humans consume a wide range of foods, drugs, and dietary supplements that are derived from plants and which modify the functioning of the central nervous sytem (CNS). The psychoactive properties of these substances are attributable to the presence of plant secondary metabolites, chemicals that are not required for the immediate survival of the plant but which are synthesized to increase the fitness of the plant to survive by allowing it to interact with its environment, including pathogens and herbivorous and symbiotic insects. In many cases, the effects of these phytochemicals on the human CNS might be linked either to their ecological roles in the life of the plant or to molecular and biochemical similarities in the biology of plants and higher animals. This review assesses the current evidence for the efficacy of a range of readily available plant-based extracts and chemicals that may improve brain function and which have attracted sufficient research in this regard to reach a conclusion as to their potential effectiveness as nootropics. Many of these candidate phytochemicals/extracts can be grouped by the chemical nature of their potentially active secondary metabolite constituents into alkaloids (caffeine, nicotine), terpenes (ginkgo, ginseng, valerian, Melissa officinalis, sage), and phenolic compounds (curcumin, resveratrol, epigallocatechin-3-gallate, Hypericum perforatum, soy isoflavones). They are discussed in terms of how an increased understanding of the relationship between their ecological roles and CNS effects might further the field of natural, phytochemical drug discovery.

    The major protein constituent of amyloid deposits in Alzheimer's disease (AD) is the amyloid beta-peptide (Abeta). In the present work, we have determined the effect of hyperforin an acylphloroglucinol compound isolated from Hypericum perforatum (St John's Wort), on Abeta-induced spatial memory impairments and on Abeta neurotoxicity. We report here that hyperforin: (1) decreases amyloid deposit formation in rats injected with amyloid fibrils in the hippocampus; (2) decreases the neuropathological changes and behavioral impairments in a rat model of amyloidosis; (3) prevents Abeta-induced neurotoxicity in hippocampal neurons both from amyloid fibrils and Abeta oligomers, avoiding the increase in reactive oxidative species associated with amyloid toxicity. Both effects could be explained by the capacity of hyperforin to disaggregate amyloid deposits in a dose and time-dependent manner and to decrease Abeta aggregation and amyloid formation. Altogether these evidences suggest that hyperforin may be useful to decrease amyloid burden and toxicity in AD patients, and may be a putative therapeutic agent to fight the disease.

    The use of botanical dietary supplements has grown steadily over the last 20 years despite incomplete information regarding active constituents, mechanisms of action, efficacy, and safety. An important but underinvestigated safety concern is the potential for popular botanical dietary supplements to interfere with the absorption, transport, and/or metabolism of pharmaceutical agents. Clinical trials of drug–botanical interactions are the gold standard and are usually carried out only when indicated by unexpected consumer side effects or, preferably, by predictive preclinical studies. For example, phase 1 clinical trials have confirmed preclinical studies and clinical case reports that St. John’s wort (Hypericum perforatum) induces CYP3A4/CYP3A5. However, clinical studies of most botanicals that were predicted to interact with drugs have shown no clinically significant effects. For example, clinical trials did not substantiate preclinical predictions that milk thistle (Silybum marianum) would inhibit CYP1A2, CYP2C9, CYP2D6, CYP2E1, and/or CYP3A4. Here, we highlight discrepancies between preclinical and clinical data concerning drug–botanical interactions and critically evaluate why some preclinical models perform better than others in predicting the potential for drug–botanical interactions. Gaps in knowledge are also highlighted for the potential of some popular botanical dietary supplements to interact with therapeutic agents with respect to absorption, transport, and metabolism.

    Two-photon excitation fluorescence (TPEF) and second-harmonic generation (SHG) are relatively new promising tools for the imaging and mapping of biological structures and processes at the microscopic level. The combination of the two image-contrast modes in a single instrument can provide unique and complementary information concerning the structure and the function of tissues and individual cells. The extended application of this novel, innovative technique by the biological community is limited due to the high price of commercial multiphoton microscopes. In this study, a compact, inexpensive and reliable setup utilizing femtosecond pulses for excitation was developed for the TPEF and SHG imaging of biological samples. Specific cell types of the nematode Caenorhabditis elegans were imaged. Detection of the endogenous structural proteins of the worm, which are responsible for observation of SHG signals, was achieved. Additionally, the binding of different photosensitizers in the HL-60 cell line was investigated, using non-linear microscopy. The sub-cellular localization of photosensitizers of a new generation, very promising for photodynamic therapy (PDT) (Hypericum perforatum L. extracts) was achieved. The sub-cellular localization of these novel photosensitizers was linked with their photodynamic action during PDT, and the possible mechanisms for cell killing have been elucidated.

    Full Text Available The aim of this study was to evaluate the usage prevalence of herbal products (HP and to ascertain the identity, mode and adverse effects of plant taxa used in self-medication practice for anxiety, depression and insomnia in patients with non-psychotic disorders originating from southeastern Serbia. Also, we compared HP users and non-users on the variables of socio-demographic characteristics, information source and origin of HP. The study was done by a face-to-face interview with a trained psychiatrist using a structured questionnaire administered to 136 adult patients suffering from non-psychotic mental disorders. A typical herbal-product user among non-psychotic psychiatric patients from southeastern Serbia is a middle-aged married woman, with a secondary level of education, unemployed and living in an urban area. Non-psychotic psychiatric patients, although not living predominantly in rural areas, were familiar with a variety of ethno-medicines and were often using HP primarily without the consultation of their psychiatrists/physicians. HP stated to be most frequently used for psychiatry-related symptoms included: Melissa officinalis, Mentha × piperita, Hypericum perforatum and Valeriana officinalis. The interviewees rarely stated adverse reactions related to the HP usage; however, this should not be generalized, since HP are known to vary in the content of their adverse reaction-causing constituents.

    Full Text Available Heavy metals polluting the natural environment are absorbed by plants. The use of herbs as components of cosmetics may pose a health risk for humans. The aim of the study was to determine the concentrations of Pb, Cd and Hg in selected species of herbs (horsetail Equisetum arvense, nettle Urtica dioica, St. John’s wort Hypericum perforatum, wormwood Artemisia absinthium, yarrow Achillea millefolium, cottonwood Solidago virgaurea self-collected from the natural environment in two different locations, and purchased in stores on the territory of Poland. The concentration of the metals studied was: 4.67–23.8 mg/kg Pb, 0.01–1.51 mg/kg Cd, 0.005–0.028 mg/kg Hg. Different concentrations of metals, depending on species and origin of plants, were found. The mean concentration of all studied metals was the lowest in St. John’s wort, and the highest in nettle. In herbs purchased in Polish stores, the concentration of Pb was higher than in plants self-collected in the natural environment.

    In the course of investigating various modes of electrochemical treatment (ECT) it has been found that graphite anode treatment begins under the ''glow mode''. A behaviour of some marks of graphite with the purpose of ECT technique development in different electrolytes has been tested. Electrolytes have been chosen of three types: highly alkaline (pH 13-14), neutral (pH-Z) and highly acidic (pH 1-2). For the first time parallel to mechanical electroerosion treatment, ECT of graphite and carbon graphite materials previously considered chemically neutral is proposed. ECT of carbon graphite materials has a number of advantages as compared with electroerrosion and mechanical ones with respect to the treatment rate and purity (ronghness) of the surface. A small quantity of sludge (6-8%) under ECT is in highly alkali electrolytes.

    Bateman, Anthony W; Gunderson, John; Mulder, Roger

    2015-02-21

    The evidence base for the effective treatment of personality disorders is insufficient. Most of the existing evidence on personality disorder is for the treatment of borderline personality disorder, but even this is limited by the small sample sizes and short follow-up in clinical trials, the wide range of core outcome measures used by studies, and poor control of coexisting psychopathology. Psychological or psychosocial intervention is recommended as the primary treatment for borderline personality disorder and pharmacotherapy is only advised as an adjunctive treatment. The amount of research about the underlying, abnormal, psychological or biological processes leading to the manifestation of a disordered personality is increasing, which could lead to more effective interventions. The synergistic or antagonistic interaction of psychotherapies and drugs for treating personality disorder should be studied in conjunction with their mechanisms of change throughout the development of each.

    2008-01-01

    Plasma waste treatment has over the past decade become a more prominent technology because of the increasing problems with waste disposal and because of the realization of opportunities to generate valuable co-products. Plasma vitrification of hazardous slags has been a commercial technology for several years, and volume reduction of hazardous wastes using plasma processes is increasingly being used. Plasma gasification of wastes with low negative values has attracted interest as a source of energy and spawned process developments for treatment of even municipal solid wastes. Numerous technologies and approaches exist for plasma treatment of wastes. This review summarizes the approaches that have been developed, presents some of the basic physical principles, provides details of some specific processes and considers the advantages and disadvantages of thermal plasmas in waste treatment applications.

  6. Portable treatment systems study

    1997-03-01

    In developing their Site Treatment Plans (STPs), many of the Department of Energy installations identified some form of portable treatment, to facilitate compliant disposition of select mixed low-level wastestreams. The Environmental Management Office of Science and Technology requested that a systems study be performed to better define the potential role of portable treatment with respect to mixed low-level waste, highlight obstacles to implementation, and identify opportunities for future research and development emphasis. The study was performed by first establishing a representative set of mixed waste, then formulating portable treatment system concepts to meet the required processing needs for these wastes. The portable systems that were conceptualized were evaluated and compared to a fixed centralized treatment alternative. The system evaluations include a life-cycle cost analysis and an assessment of regulatory, institutional, and technical issues associated with the potential use of portable systems. The results of this study show that when all costs are included, there are no significant cost differences between portable systems and fixed systems. However, it is also emphasized that many uncertainties exist that could impact the cost of implementing portable treatment systems. Portable treatment could be made more attractive through private sector implementation, although there is little economic incentive for a commercial vendor to develop small, specialized treatment capabilities with limited applicability. Alternatively, there may also be valid reasons why fixed units cannot be used for some problematic wastestreams. In any event, there are some site-specific problems that still need to be addressed, and there may be some opportunity for research and development to make a positive impact in these areas.

  10. Endovascular treatment in pregnancy

    International Nuclear Information System (INIS)

    Ishii, Akira; Miyamoto, Susumu

    2013-01-01

    There is an increased risk of stroke during pregnancy and the puerperium. Decisions should be made immediately upon transfer to each institution, particularly with respect to when and how to treat the patient. This review highlights the feasibility of endovascular treatment in pregnancy. Most of the pharmaceutical agents and therapeutic devices used in clinical practice can be utilized in pregnant patients. Comprehensive information on the benefits and risks of treatment should be explained to the patient and her family, with particular attention to the safety of the mother and fetus. Radiation exposure to the fetus is also a concern; the hazard can be minimized with optimal protection. Several studies have demonstrated that conventional procedures do not cause serious radiation exposure exceeding the threshold of safety to the fetus. Endovascular therapy can be safely performed for the treatment of acute stroke as in non-pregnant patients with adequate attention to pharmaceutical agents and shielding from radiation. In contrast to therapy for acute stroke, preventive endovascular treatment for asymptomatic lesions remains controversial. Several conditions, such as cerebral aneurysms and arteriovenous malformations, are known to bleed more frequently in pregnancy, but whether the benefits of preventive treatment outweigh the associated risks is unknown. The decision for preventive treatment should be carefully made on a case-by-case basis after extensive discussion with the patient. (author)

  12. HORMONAL TREATMENT IN UROGYNECOLOGY

    Directory of Open Access Journals (Sweden)

    Adolf Lukanović

    2018-02-01

    Full Text Available Background. Hormonal treatment in urogynecology is based on the knowledge, that urinary and reproductive tracts have common embriologic origin and are also linked anatomically and functionally. Both systems are functioning and changing due to sex steroids influence. Decreased estrogen concentrations are connected to metabolic and trophic changes in all organs with estrogen receptors, i.e. also in urogenital tract. Atrophy of urogenital system in postmenopause is a common causative factor for stress urinary incontinence (SUI and urge incontinence (UUI. In both estrogen replacement treatment have been introduced, but meta-analyses of the available literature indicate that estrogen therapy is effective only if given vaginaly. Recurrent urinary tract infections (RUTI occur in postmenopause often as a consequence of structural changes in urinary and reproductive tract to lowered immune protection and colonization with eneterobacteria. In RUTI too, estrogen replacement treatment have been used with the results similar to those with SUI and UUI. Effectiveness of estrogen treatment was evident only in topically applied vaginaly, while oral administration has the same effectiveness as placebo. Conclusions. Structural changes in urogenital tract in postmenopause are the results of estrogen depletion. Estrogen replacement is effective in cases of SUI, UUI and RUTI if it is applied topicaly, the efffect being influenced by the type of estrogen used and duration of treatment.

  13. Hyperthyroidism: diagnosis and treatment.

    Science.gov (United States)

    Reid, Jeri R; Wheeler, Stephen F

    2005-08-15

    The proper treatment of hyperthyroidism depends on recognition of the signs and symptoms of the disease and determination of the etiology. The most common cause of hyperthyroidism is Graves' disease. Other common causes include thyroiditis, toxic multinodular goiter, toxic adenomas, and side effects of certain medications. The diagnostic workup begins with a thyroid-stimulating hormone level test. When test results are uncertain, measuring radionuclide uptake helps distinguish among possible causes. When thyroiditis is the cause, symptomatic treatment usually is sufficient because the associated hyperthyroidism is transient. Graves' disease, toxic multinodular goiter, and toxic adenoma can be treated with radioactive iodine, antithyroid drugs, or surgery, but in the United States, radioactive iodine is the treatment of choice in patients without contraindications. Thyroidectomy is an option when other treatments fail or are contraindicated, or when a goiter is causing compressive symptoms. Some new therapies are under investigation. Special treatment consideration must be given to patients who are pregnant or breastfeeding, as well as those with Graves' ophthalmopathy or amiodarone-induced hyperthyroidism. Patients' desires must be considered when deciding on appropriate therapy, and dose monitoring is essential.

    Hallman, Guy J.

    2012-07-01

    The history of the development of generic phytosanitary irradiation (PI) treatments is discussed beginning with its initial proposal in 1986. Generic PI treatments in use today are 150 Gy for all hosts of Tephritidae, 250 Gy for all arthropods on mango and papaya shipped from Australia to New Zealand, 300 Gy for all arthropods on mango shipped from Australia to Malaysia, 350 Gy for all arthropods on lychee shipped from Australia to New Zealand and 400 Gy for all hosts of insects other than pupae and adult Lepidoptera shipped to the United States. Efforts to develop additional generic PI treatments and reduce the dose for the 400 Gy treatment are ongoing with a broad based 5-year, 12-nation cooperative research project coordinated by the joint Food and Agricultural Organization/International Atomic Energy Agency Program on Nuclear Techniques in Food and Agriculture. Key groups identified for further development of generic PI treatments are Lepidoptera (eggs and larvae), mealybugs and scale insects. A dose of 250 Gy may suffice for these three groups plus others, such as thrips, weevils and whiteflies.

    Following a general introduction, a chain consisting of three computer programs which has been developed for treatment planning of external beam radiotherapy without manual intervention is described. New score functions used for determination of optimal incidence directions are presented and the calculation of the position of the isocentre for each optimum combination of incidence directions is explained. A description of how a set of applicators, covering fields with dimensions of 4 to 20 cm, for the 6 to 20 MeV electron beams of a MEL SL75-20 linear accelerator was developed, is given. A computer program for three dimensional electron beam treatment planning is presented. A microprocessor based treatment planning system for the Selectron remote controlled afterloading system for intracavitary radiotherapy is described. The main differences in treatment planning procedures for external beam therapy with neutrons instead of photons is discussed. A microprocessor based densitometer for plotting isodensity lines in film dosimetry is described. A computer program for dose planning of brachytherapy is presented. Finally a general discussion about the different aspects of computerized treatment planning as presented in this thesis is given. (Auth.)

    Silberstein, Stephen D.

    2015-01-01

    Purpose of Review: This article reviews the evidence base for the preventive treatment of migraine. Recent Findings: Evidence-based guidelines for the preventive treatment of migraine have recently been published by the American Academy of Neurology (AAN) and the Canadian Headache Society (CHS), providing valuable guidance for clinicians. Strong evidence exists to support the use of metoprolol, timolol, propranolol, divalproex sodium, sodium valproate, and topiramate for migraine prevention, according to the AAN. Based on best available evidence, adverse event profile, and expert consensus, topiramate, propranolol, nadolol, metoprolol, amitriptyline, gabapentin, candesartan, Petasites (butterbur), riboflavin, coenzyme Q10, and magnesium citrate received a strong recommendation for use from the CHS. Summary: Migraine preventive drug treatments are underutilized in clinical practice. Principles of preventive treatment are important to improve compliance, minimize side effects, and improve patient outcomes. Choice of preventive treatment of migraine should be based on the presence of comorbid and coexistent illness, patient preference, reproductive potential and planning, and best available evidence.

  18. Treatment Deployment Evaluation Tool

    1999-01-01

    The U.S. Department of Energy (DOE) is responsible for the final disposition of legacy spent nuclear fuel (SNF). As a response, DOE's National Spent Nuclear Fuel Program (NSNFP) has been given the responsibility for the disposition of DOE-owned SNF. Many treatment technologies have been identified to treat some forms of SNF so that the resulting treated product is acceptable by the disposition site. One of these promising treatment processes is the electrometallurgical treatment (EMT) currently in development; a second is an Acid Wash Decladding process. The NSNFP has been tasked with identifying possible strategies for the deployment of these treatment processes in the event that a treatment path is deemed necessary. To support the siting studies of these strategies, economic evaluations are being performed to identify the least-cost deployment path. This model (tool) was developed to consider the full scope of costs, technical feasibility, process material disposition, and schedule attributes over the life of each deployment alternative. Using standard personal computer (PC) software, the model was developed as a comprehensive technology economic assessment tool using a Life-Cycle Cost (LCC) analysis methodology. Model development was planned as a systematic, iterative process of identifying and bounding the required activities to dispose of SNF. To support the evaluation process, activities are decomposed into lower level, easier to estimate activities. Sensitivity studies can then be performed on these activities, defining cost issues and testing results against the originally stated problem

    2014-01-01

    Full Text Available Ameloblastoma is the second most common benign odontogenic tumour (Shafer et al. 2006 which constitutes 1–3% of all cysts and tumours of jaw, with locally aggressive behaviour, high recurrence rate, and a malignant potential (Chaine et al. 2009. Various treatment algorithms for ameloblastoma have been reported; however, a universally accepted approach remains unsettled and controversial (Chaine et al. 2009. The treatment algorithm to be chosen depends on size (Escande et al. 2009 and Sampson and Pogrel 1999, anatomical location (Feinberg and Steinberg 1996, histologic variant (Philipsen and Reichart 1998, and anatomical involvement (Jackson et al. 1996. In this paper various such treatment modalities which include enucleation and peripheral osteotomy, partial maxillectomy, segmental resection and reconstruction done with fibula graft, and radical resection and reconstruction done with rib graft and their recurrence rate are reviewed with study of five cases.

  1. Treatment of midfacial fractures

    2007-01-01

    Fractures of the midface constitute half of all traumas involving facial bones. Computed tomography is very useful in primary diagnosis. Isolated fractures of the nasal bone and lateral midfacial structures may be diagnosed sufficiently by conventional X-rays. An exact description of the fracture lines along the midfacial buttresses is essential for treatment planning. For good aesthetics and function these have to be reconstructed accurately, which can be checked with X-rays. The treatment of midfacial fractures has been revolutionized over the last two decades. A stable three-dimensional reconstruction of the facial shape is now possible and the duration of treatment has shortened remarkably. The frequently occurring isolated fractures in the lateral part of the midface may be treated easily and effectively by semisurgical methods such as the Gillies procedure or hook-repositioning.

  2. Treatment decisions under ambiguity.

    Berger, Loïc; Bleichrodt, Han; Eeckhoudt, Louis

    2013-05-01

    Many health risks are ambiguous in the sense that reliable and credible information about these risks is unavailable. In health economics, ambiguity is usually handled through sensitivity analysis, which implicitly assumes that people are neutral towards ambiguity. However, empirical evidence suggests that people are averse to ambiguity and react strongly to it. This paper studies the effects of ambiguity aversion on two classical medical decision problems. If there is ambiguity regarding the diagnosis of a patient, ambiguity aversion increases the decision maker's propensity to opt for treatment. On the other hand, in the case of ambiguity regarding the effects of treatment, ambiguity aversion leads to a reduction in the propensity to choose treatment. Copyright © 2013 Elsevier B.V.

    2015-06-01

    Full Text Available Current treatment of endometriosis is mainly based on surgery and ovarian suppressive agents (oral contraceptives, progestins, GnRh agonist and androgenic agents. Hormonal treatments are often associated with unwanted effects, delayed conception and recurrence of disease and symptoms when stopped. For these reasons, new drugs that aim new targets are required to cause regression of the disease & symptoms without adverse hypo-estrogenic effects. This review aims to provide an update on the new drugs used for treatment of endometriosis. These include the levonorgestrel-releasing intrauterine device, GnRH antagonists, aromatase inhibitors, selective estrogen-receptor modulators, progesterone antagonist, selective progesterone receptor modulators, angiogenesis inhibitors, and immunomodulatory drugs.

  4. Cancer treatment: what's ahead?

    International Nuclear Information System (INIS)

    Parvez, T.

    2005-01-01

    Surgery, chemotherapy, and radiation therapy are standard modalities for cancer treatment. Biological therapy (immunotherapy, biotherapy, or biological response modifier therapy) is a comparatively novel addition to this armamentarium. Biological therapies use the body's immune system, either directly or indirectly, to fight cancer or to lessen the side effects that may be caused by some cancer treatments. Biological therapeutic agents include interferons, interleukins, colony-simulating factors, monoclonal antibodies, vaccines, gene therapy, and nonspecific immunomodulating agents. A promising form of cancer treatment is immunotherapy. Immunotherapy for cancer is essentially the stimulation of the immune system through a variety of reagents such as vaccines, infusion of T-cells, or cytokines. These reagents act through one of several mechanisms including stimulating the anti-tumour response, decreasing suppressor mechanisms, altering tumour cells to increase their immunogenicity and making them more susceptible to immunologic defenses, and improving tolerance to cytotoxic agents or radiotherapy. This review describes some novel approaches in the immunotherapy in cancer. (author)

    Creativity can be defined as the ability to understand, develop, and express, in a systematic fashion, novel orderly relationships. It is sometimes difficult to separate cognitive skills requisite for the creative process from the drive that generates unique new ideas and associations. Epilepsy itself may affect the creative process. The treatment of epilepsy and its comorbidities, by altering or disrupting the same neural networks through antiseizure drugs (ASDs), treatment of epilepsy comorbidities, ablative surgery, or neurostimulation may also affect creativity. In this review, we discuss the potential mechanisms by which treatment can influence the creative process and review the literature on the consequences of therapy on different aspects of creativity in people with epilepsy.

  6. Hyperthyroidism: Diagnosis and Treatment.

    Science.gov (United States)

    Kravets, Igor

    2016-03-01

    Hyperthyroidism is an excessive concentration of thyroid hormones in tissues caused by increased synthesis of thyroid hormones, excessive release of preformed thyroid hormones, or an endogenous or exogenous extrathyroidal source. The most common causes of an excessive production of thyroid hormones are Graves disease, toxic multinodular goiter, and toxic adenoma. The most common cause of an excessive passive release of thyroid hormones is painless (silent) thyroiditis, although its clinical presentation is the same as with other causes. Hyperthyroidism caused by overproduction of thyroid hormones can be treated with antithyroid medications (methimazole and propylthiouracil), radioactive iodine ablation of the thyroid gland, or surgical thyroidectomy. Radioactive iodine ablation is the most widely used treatment in the United States. The choice of treatment depends on the underlying diagnosis, the presence of contraindications to a particular treatment modality, the severity of hyperthyroidism, and the patient's preference.

It commonly present as round patches of hair loss which can be the firstmanifestationofamoreseverealopecia totalis or universalis. The cause of AA is unknown although most evidence supports the hypothesis that AA is an immunologically mediated disease. Treatment of AA may be divided into four different categories of widely accepted therapeutic modalities: immune inhibitors (steroid or psoralen and UVA light- PUVA, topicalsensitizers (squaric acid dibutylester and diphenylcyclopropenone, non-specificirritants(anthralinandthevasodilatator minoxidil.

    Full Text Available Childhood vitiligo differs from the adults by showing a higher incidence in females, segmental vitiligo being more common and less frequent association with other systemic autoimmune and endocrine disorders.Childhood vitiligo is often associated with a marked psychosocial and long lasting effect on the self-esteem of the affected children and their parents, hence an adequate treatment is very essential. Treatment of vitiligo is indeed a tough challenge for the dermatologists′ more so in the background of childhood vitiligo. Although multiple therapeutic modalities are available in the therapeutic armamentarium, not all can be used in children. This brief report updates regarding various therapies available in the treatment of childhood vitiligo.

  9. New treatments for gout.

    Mapa, Janet B; Pillinger, Michael H

    2010-05-01

    Gout is a commonly occurring medical condition that can lead to significant morbidity. Therapies available for the treatment of both acute and chronic gouty arthritis have not changed significantly since the 1960s. Although these treatments are well established, they are often contraindicated in the presence of various different comorbidities, including diabetes, renal insufficiency, hypertension and gastrointestinal disease, all of which can occur frequently in patients with gout. Therefore, new treatments are needed. This review describes recent advances in therapeutics for gout, including drugs designed to reduce levels of urate and to inhibit acute or chronic inflammation. While some of these strategies are currently available, others are undergoing regulatory evaluation or are at earlier stages of development.

  10. Amblyopia update: new treatments.

    Science.gov (United States)

    Vagge, Aldo; Nelson, Leonard B

    2016-09-01

    This review article is an update on the current treatments for amblyopia. In particular, the authors focus on the concepts of brain plasticity and their implications for novel treatment strategies for both children and adults affected by amblyopia. A variety of strategies has been developed to treat amblyopia in children and adults. New evidence on the pathogenesis of amblyopia has been obtained both in animal models and in clinical trials. Mainly, these studies have challenged the classical concept that amblyopia becomes untreatable after the 'end' of the sensitive or critical period of visual development, because of a lack of sufficient plasticity in the adult brain. New treatments for amblyopia in children and adults are desirable and should be encouraged. However, further studies should be completed before such therapies are widely accepted into clinical practice.

  12. Thyroxin hormone suppression treatment

    International Nuclear Information System (INIS)

    Samuel, A.M.

    1999-01-01

    One of the important modalities of treatment of thyroid cancer (TC) after surgery is the administration of thyroxin as an adjuvant treatment. The analysis supports the theory that thyroid suppression plays an important role in patient management. 300 μg of thyroxin, as this is an adequate dose for suppression is given. Ideally the dose should be tailored by testing s-TSH levels. However, since a large number of the patients come from out station cities and villages this is impractical. We therefore depend on clinical criteria of hyperthyroid symptoms and adjust the dose. Very few patients need such adjustment

    Wood, S F

    1989-01-01

    The range of treatments for hay fever available to the general practitioner has changed considerably in recent years. New antihistamines have addressed the problem of sedation and moved towards one daily dose; nasally applied corticosteroids avoid the need for systemic steroid therapy and its potential adverse effect; and regulatory decisions have set a trend away from immunotherapy in general practice. However, knowledge about the mechanism of action of immunotherapy is increasing and new developments with improved safety profiles include allergen polymers, allergoids, oral immunotherapy and nasal immunotherapy. Choice of treatment depends, as always, on the individual circumstances of the patient and his or her disease. PMID:2556545

    Visibility and durability of materials used to delineate shoulders and medians adjacent to asphalt pavements were evaluated. Materials evaluated were polysulfide and coal tar epoxies, one and two component polyesters, portland cement, acrylic paints, modified-alkyd traffic paint, preformed plastic tape, and thermoplastic markings. Neat applications, sand mortars, and surface treatments were installed in several geometric patterns including cross hatches, solid median treatments, and various widths of edge lines. Thermoplastic pavement markings generally performed very well, providing good visibility under adverse viewing conditions for at least 4 years. Thermoplastic 4 in. wide edge lines appear to provide adequate visibility for most conditions.

    Directory of Open Access Journals (Sweden)

    2009-06-01

    Full Text Available Kleptomania is a rare disorder with inability or great difficulty in resisting impulses of stealing. People with this disorder are compelled to steal things, generally things of little or no value. This disorder usually begins during puberty and usually last until late adulthood; in some cases lasts throughout the person's life. People with this disorder are likely to have a comorbid conditions like mood disorders. Individuals with the disorder are usually referred for treatment due to the comorbid psychiatric complaints rather than kleptomanic behaviour per se. On the other hand literature lacks of studies about the treatment of kleptomania. A wide variety of therapeutic strategies have been proposed for its treatment, among them psychoanalytic oriented psychotherapy, behavioral therapy and pharmacotherapy. Some medications that are used for people diagnosed with kleptomania are selective serotonin reuptake inhibitors, mood stabilizers and opioid antagonists. There is evidence from numerous case studies that a variety of cognitive behavioral therapy techniques are effective in the treatment of kleptomania and it is favored over other approaches such as psychodynamic and psychoanalytic therapies. Studies to date suggest that cognitive behavioral therapy when used in combination with medication, is more effective than medication alone.

  14. Plasma treatment of onychomycosis

    Science.gov (United States)

    Xiong, Zilan; Roe, Jeff; Grammer, Tim; Him, Yeon-Ho; Graves, David B.

    2015-09-01

    Onychomycosis or fungal infection of the toenail or fingernail is a common affliction. Approximately 10% of the world's adult population is estimated to suffer from onychomycosis. Current treatment options such as topical creams, oral drugs, or laser treatments are generally limited by a variety of problems. We present results for an alternative onychomycosis treatment scheme using atmospheric pressure cold air plasmas. Using thinned cow hoof as a model nail material, we tested the ability of various plasma sources to act through the model nail to eradicate either bacteria or fungus deposited on the opposite side. Following 20 minute exposure to a surface microdischarge (SMD) device operating in room air, we observed a ~ 2 log reduction of E. coli. A similar result was obtained against T. rubrum after 45 min plasma treatment. NOx species concentration penetrating through the model nail as well as uptake into the nail were measured as a function of nail thickness. We propose that these plasma-generated species, or perhaps their reaction products, are responsible for at least part of the observed anti-microbial effect. We also explore the use of ultraviolet light acting in synergy with plasma-generated chemical species.

On the other hand, in narcolepsy type 2, cerebrospinal fluid hypocretin-1 levels are normal and cataplexy absent. Despite major advances in our understanding of narcolepsy mechanisms, its current management is only symptomatic. Treatment options may vary from a single drug that targets several symptoms, or multiple medications that each treats a specific symptom. In recent years, narcolepsy treatment has changed with the widespread use of modafinil/armodafinil for daytime sleepiness, antidepressants (selective serotonin and dual serotonin and noradrenalin reuptake inhibitors) for cataplexy, and sodium oxybate for both symptoms. Other psychostimulants can also be used, such as methylphenidate, pitolisant and rarely amphetamines, as third-line therapy. Importantly, clinically relevant subjective and objective measures of daytime sleepiness are required to monitor the treatment efficacy and to provide guidance on whether the treatment goals are met. Associated symptoms and comorbid conditions, such as hypnagogic/hypnopompic hallucinations, sleep paralysis, disturbed nighttime sleep, unpleasant dreams, REM- and non REM-related parasomnias, depressive symptoms, overweight/obesity, and obstructive sleep apnea, should also be taken into account and managed, if required. In the near future, the efficacy of new wake-promoting drugs, anticataplectic agents, hypocretin replacement therapy and immunotherapy at the early stages of the disease should also be evaluated.

    Lang, Kyle M; Little, Todd D

    2018-04-01

    We review a number of issues regarding missing data treatments for intervention and prevention researchers. Many of the common missing data practices in prevention research are still, unfortunately, ill-advised (e.g., use of listwise and pairwise deletion, insufficient use of auxiliary variables). Our goal is to promote better practice in the handling of missing data. We review the current state of missing data methodology and recent missing data reporting in prevention research. We describe antiquated, ad hoc missing data treatments and discuss their limitations. We discuss two modern, principled missing data treatments: multiple imputation and full information maximum likelihood, and we offer practical tips on how to best employ these methods in prevention research. The principled missing data treatments that we discuss are couched in terms of how they improve causal and statistical inference in the prevention sciences. Our recommendations are firmly grounded in missing data theory and well-validated statistical principles for handling the missing data issues that are ubiquitous in biosocial and prevention research. We augment our broad survey of missing data analysis with references to more exhaustive resources.

  13. [Prophylactic treatments of migraine].

    Science.gov (United States)

    Massiou, H

    2000-01-01

    Prophylactic treatment is mainly intended to reduce the frequency of migraine attacks. It is usually proposed to patients who suffer from two or more attacks per month. It should also be considered in patients who suffer from less frequent, but prolonged, disabling attacks with a poor response to abortive treatment, and who consider that their quality of life is reduced between attacks. Excessive intake of acute medication, more than twice a week, is a strong indication for prophylactic treatment. In order to obtain a good compliance to treatment, the patient must be informed of the expected efficacy of the drugs, and of their most frequent side effects. Thus, the choice of a prophylactic drug is made together with the patient. Based on the results of published controlled trials, the main prophylactic drugs are some betablockers, methysergide, pizotifene, oxetorone, flunarizine, amitriptyline, NSAIDs, and sodium valproate. Some less evaluated drugs such as aspirin, DHE, indoramine, verapamil, may be useful. Other substances such as riboflavin and new antiepileptic dugs are being evaluated. The choice of the drug to start with depends on several considerations. The first step is to make sure that there are no contra indications, and no possible interaction with the abortive medications. Then, possible side effects will be taken into account, for example, weight gain is a problem for most young women and patients who practice sports may not tolerate betablockers. Associated pathologies have to be checked. For example, a hypertensive migraine sufferers may benefit from betablockers; in a patient who suffers both from migraine and tension type headaches or from depression, amitriptyline is the first choice drug. The type of migraine should also be considered; for instance, in frequent attacks with aura, aspirin is recommended and betablockers avoided. In most cases, prophylaxis should be given as monotherapy, and it is often necessary to try successively several drugs

  14. Treatment of tinea capitis.

    Abdel-Rahman, S M; Nahata, M C

    1997-03-01

    To review the epidemiology, pathogenesis, mycology, clinical presentation, and pharmacotherapy of tinea capitis, and describe the role of newer antimycotic agents. A MEDLINE search restricted to English-language articles published from 1966 through 1996 and journal references were used in preparing this review. The data on mycology, pharmacokinetics, adverse effects, and drug interactions were obtained from controlled studies and case reports appearing in the literature. Both open-label and comparative studies were evaluated to assess the efficacy of antimycotics in the treatment of this infection. Griseofulvin is the drug of choice in the treatment of tinea capitis. Newer agents with greater efficacy or shorter treatment durations continue to be explored. Ketoconazole, the first azole studied for efficacy in tinea capitis, has not demonstrated any clinical advantage over griseofulvin in several controlled clinical trials. Itraconazole is effective, but the available data are limited to case reports and a single uncontrolled study. Terbinafine similarly has shown promise in the treatment of tinea capitis, but the oral formulation was only recently approved in the US. Existing studies reflect the results in infection with pathogens not seen in the US. Both itraconazole and terbinafine achieve high concentrations in the hair and stratum corneum that persist for several weeks following drug administration. This may enable shorter courses of therapy; however, comparative studies need to be conducted in the US. Tinea capitis remains the most common dermatophyte infection in young urban children. Oral antifungal therapy is required for effective treatment, often for several months. The combination of griseofulvin with a selenium sulfide shampoo continues to be the mainstay of therapy until more experience is gained with the newer antimycotics.

  15. Personality does not predict treatment preference, treatment experience does: a study of four complementary pain treatments.

    Blasche, Gerhard; Melchart, Herbert; Leitner, Daniela; Marktl, Wolfgang

    2007-10-01

    The aim of the present study was to determine the extent to which personality and treatment experience affect patients' appraisals of 4 complementary treatments for chronic pain. A total of 232 chronic pain patients (164 females, 68 males, average age 56.6 years) visiting a spa clinic in Austria returned a questionnaire on patient characteristics and personality (autonomy, depressiveness, assertiveness, self-control) as well as attitudes towards (i.e. appealing, effective, pleasant) and experience of the treatments. Results were analysed by use of linear regression analysis and confidence intervals. Although all treatments were appraised positively, the passive treatments (thermal water tub baths, classical massage) were favoured more than the active treatments (relaxation training or exercise therapy). Treatment appraisal was not predicted by any of the personality traits but to a large extent by treatment experience. Relaxing, not unpleasant treatments were the most highly esteemed treatments. How strenuous or tiring a treatment was only had a minor effect on its appraisal. Neither do dependent, passive patients prefer passive treatments, nor do conscientious patients prefer active treatments. Instead, the appraisal of treatments that induce specific somatosensory sensations is largely determined by treatment experiences, i.e. what the treatment feels like. Despite the popularity of CAM which encompasses many experientially intensive treatments, treatment experience has to date been a neglected topic of treatment research.

    Roy-Byrne, Peter

    2015-01-01

    A sizable proportion of psychiatric patients will seek clinical evaluation and treatment for anxiety symptoms reportedly refractory to treatment. This apparent lack of response is either due to “pseudo-resistance” (a failure to have received and adhered to a recognized and effective treatment or treatments for their condition) or to true “treatment resistance.” Pseudo-resistance can be due to clinician errors in selecting and delivering an appropriate treatment effectively, or to patient nonadherence to a course of treatment. True treatment resistance can be due to unrecognized exogenous anxiogenic factors (eg, caffeine overuse, sleep deprivation, use of alcohol or marijuana) or an incorrect diagnosis (eg, atypical bipolar illness, occult substance abuse, attention deficit-hyperactivity disorder). Once the above factors are eliminated, treatment should focus on combining effective medications and cognitive behavioral therapy, combining several medications (augmentation), or employing novel medications or psychotherapies not typically indicated as first-line evidence-based anxiety treatments.

    Full Text Available Purpose: To analyse the classifications and the conservative protocols used by hand surgery operative’s units and published in the last 15 years. To draw a comparison between those classifications and protocols and the ones used in our unit. Material and Methods: The published conservative treatments have been analysed and then our protocol has been described through the analysis of three cases currently treated in our division. Results: It has been highlighted that camptodactyly classifications are not homogeneous. Moreover, in conservative treatment, different typology and posology of splints have been adopted. Our unit uses the Foucher’s classification to define the type of splint that it is necessary. Conclusions: Despite the authors choose different types of splint, they agree that in the most cases of camptodactily the initial approach is conservative. In our unit static and dynamic splints are made directly on the patient’s hand and they are monitored with goniometrical measurements, obtaining great results.

    Japan Atomic Energy Research Institute (JAERI) is equipped with such atomic energy facilities as a power test reactor, four research reactors, a hot laboratory, and radioisotope-producing factory. All the radioactive wastes but gas generated from these facilities are treated by the waste treatment facilities established in JAERI. The wastes carried into JAERI through Japan Radioisotope Association are also treated there. Low level water solution is treated with an evaporating apparatus, an ion-exchange apparatus, and a cohesive precipitating apparatus, while medium level solution is treated with an evaporating apparatus, and low level combustible solid is treated with an incinerating apparatus. These treated wastes and sludges are mixed with Portland cement in drum cans to solidify, and stored in a concrete pit. The correct classification and its indication as well as the proper packing for the wastes are earnestly demanded by the treatment facilities. (Kobatake, H.)

    Remediation efforts at the U.S. Department of Energy's Hanford Site require that many technical and scientific principles be combined for effectively managing and disposing the variety of wastes currently stored in underground tanks. Based on these principles, pretreatment technologies are being studied and developed to separate waste components and enable the most suitable treatment methods to be selected for final disposal of these wastes. The Tank Waste Treatment Science Task at Pacific Northwest Laboratory is addressing pretreatment technology development by investigating several aspects related to understanding and processing the tank contents. The experimental work includes evaluating the chemical and physical properties of the alkaline wastes, modeling sludge dissolution, and evaluating and designing ion exchange materials. This paper gives some examples of results of this work and shows how these results fit into the overall Hanford waste remediation activities. This work is part of series of projects being conducted for the Tank Waste Remediation System

  3. Electrocoagulation in Water Treatment

    Science.gov (United States)

    Liu, Huijuan; Zhao, Xu; Qu, Jiuhui

    Electrocoagulation (EC) is an electrochemical method of treating polluted water where sacrificial anodes corrode to release active coagulant precursors (usually aluminum or iron cations) into solution. At the cathode, gas evolves (usually as hydrogen bubbles) accompanying electrolytic reactions. EC needs simple equipments and is designable for virtually any size. It is cost effective and easily operable. Specially, the recent technical improvements combined with a growing need for small-scale water treatment facilities have led to a revaluation of EC. In this chapter, the basic principle of EC was introduced first. Following that, reactions at the electrodes and electrode assignment were reviewed; electrode passivation process and activation method were presented; comparison between electrocoagulation and chemical coagulation was performed; typical design of the EC reactors was also described; and factors affecting electrocoagulation including current density, effect of conductivity, temperature, and pH were introduced in details. Finally, application of EC in water treatment was given in details.

  4. Internal radioactive contamination treatment

    Tobajas, L. M.

    1998-01-01

    In a radiological emergency, the internal radioactive contamination becomes a therapeutic urgency and must be established as fast as possible. Just when a radioactive contamination accident occurs, it is difficult to know exactly the amount of radioactive materials absorbed and to estimate the dose received.. The decision to be taken after the incorporation of the radioactive material depends on the method and on the Radiological Protection Department collaboration. Any treatment achieving a reduction of the doses received or expected will be useful. The International Radiological Protection Commission doesn't recommend the use of the dose limit, to decide about the intervention necessity. However the LIA can be used as the reference point to establish the necessity and reach of the treatment. The object of the present work, is to introduce the general principles to carry out the internal people decontamination, under the last international recommendations. (Author) 4 refs

    A large scale production of GaAs based solar cells with MOCVD will give rise to a considerable use of arsine. Therefore a gas treatment system is needed to convert the waste gases into less toxic compounds. In this study seven different gas treatment systems for MOCVD are compared by quantifying the environmental aspects. The systems are divided in wet systems, adsorption systems and thermal systems. The smallest amount of waste is produced by adsorption and thermal systems. Adsorption systems use the smallest amount of energy. The amount of primary materials used for the equipment varies per system. All systems are safe, but adsorption systems are simplest. At the moment, adsorption systems are probably the best choice from an environmental point of view. Nevertheless thermal systems have some potential advantages which make them interesting for the future

    2014-08-15

    Impetigo is the most common bacterial skin infection in children two to five years of age. There are two principal types: nonbullous (70% of cases) and bullous (30% of cases). Nonbullous impetigo, or impetigo contagiosa, is caused by Staphylococcus aureus or Streptococcus pyogenes, and is characterized by honey-colored crusts on the face and extremities. Impetigo primarily affects the skin or secondarily infects insect bites, eczema, or herpetic lesions. Bullous impetigo, which is caused exclusively by S. aureus, results in large, flaccid bullae and is more likely to affect intertriginous areas. Both types usually resolve within two to three weeks without scarring, and complications are rare, with the most serious being poststreptococcal glomerulonephritis. Treatment includes topical antibiotics such as mupirocin, retapamulin, and fusidic acid. Oral antibiotic therapy can be used for impetigo with large bullae or when topical therapy is impractical. Amoxicillin/clavulanate, dicloxacillin, cephalexin, clindamycin, doxycycline, minocycline, trimethoprim/sulfamethoxazole, and macrolides are options, but penicillin is not. Natural therapies such as tea tree oil; olive, garlic, and coconut oils; and Manuka honey have been anecdotally successful, but lack sufficient evidence to recommend or dismiss them as treatment options. Treatments under development include minocycline foam and Ozenoxacin, a topical quinolone. Topical disinfectants are inferior to antibiotics and should not be used. Empiric treatment considerations have changed with the increasing prevalence of antibiotic-resistant bacteria, with methicillin-resistant S. aureus, macrolide-resistant streptococcus, and mupirocin-resistant streptococcus all documented. Fusidic acid, mupirocin, and retapamulin cover methicillin-susceptible S. aureus and streptococcal infections. Clindamycin proves helpful in suspected methicillin-resistant S. aureus infections. Trimethoprim/sulfamethoxazole covers methicillin-resistant S

    2008-02-01

    More than half of the European population are overweight (body mass index (BMI) > 25 and or = 30 kg/m2). Being overweight and obesity are becoming endemic, particularly because of increasing nourishment and a decrease in physical exercise. Insulin resistance, type 2 diabetes, dyslipidemia, hypertension, cholelithiasis, certain forms of cancer, steatosis hepatis, gastroesophageal reflux, obstructive sleep apnea, degenerative joint disease, gout, lower back pain, and polycystic ovary syndrome are all associated with overweight and obesity. The endemic extent of overweight and obesity with its associated comorbidities has led to the development of therapies aimed at weight loss. The long-term effects of diet, exercise, and medical therapy on weight are relatively poor. With respect to durable weight reduction, bariatric surgery is the most effective long-term treatment for obesity with the greatest chances for amelioration and even resolution of obesity-associated complications. Recent evidence shows that bariatric surgery for severe obesity is associated with decreased overall mortality. However, serious complications can occur and therefore a careful selection of patients is of utmost importance. Bariatric surgery should at least be considered for all patients with a BMI of more than 40 kg/m2 and for those with a BMI of more than 35 kg/m2 with concomitant obesity-related conditions after failure of conventional treatment. The importance of weight loss and results of conventional treatment will be discussed first. Currently used operative treatments for obesity and their effectiveness and complications are described. Proposed criteria for bariatric surgery are given. Also, some attention is devoted to more basic insights that bariatric surgery has provided. Finally we deal with unsolved questions and future directions for research.

    Waste Treatment Plant (WTP) is designed to provide appropriate systems for processing, immobilization and storage of low and medium radioactive waste arising from the operation of the research facilities of the Nuclear Technology Centre (NTC). It will serve as central collection station processing active waste generated through application of radionuclide in science, medicine and industry in the country. WTP building and structures will house the main waste processing systems and supporting facilities. All facilities will be interconnected. The interim storage building for processed waste drums will be located separately nearby. The separate interim storage building is located near the waste treatment building. Considering the low radiation level of the waste, storage building is large with no solid partitioning walls and with no services or extra facilities other than lighting and smoke alarm sensors. The building will be designed such that drums(200-1)are stacked 3 units high using handling by fork lift truck. To prevent radiation exposure to on-site personnel, the interim storage building will be erected apart from waste treatment plant or other buildings. The interim storage building will also be ready for buffer storage of unconditioned waste waiting for processing or decay and for storage material from the WTP

    Full Text Available Obesity is a disease with severe health consequences and increased risk of mortality. The most commonly used criteria to assess the presence and the severity of obesity are body mass index, waist circumference, waist-to-height ratio and the presence of the health conditions caused or worsened by obesity. Worldwide obesity has more than doubled in the last 4 decades. Obesity is the second of the leading preventable causes of death worldwide (after smoking. Obesity has a plurifactorial pathogenesis. The central perturbation consists in the imbalance between calories intake and calories consumption (by inappropriate diet and sedentary lifestyle. Identification of all the ethiological factors is important for treatment and prophylaxis. Weight loss benefits are multiple and important: improvement in glicemic control and in plasma lipid levels, blood presure control, obstructiv sleep apneea reduction, improvement in management of daily activities and profesional performances, increase quality of life, reduction in mortality. Overweight or obese patient will complete a diagnostic and a treatment program. Treatment of obesity claims a targeted multidimensional therapy: weight and lifestyle management, diet, sustained physical activity in daily life, exercise, decrease life stressors, smoking cessation, drug therapy, bariatric surgery psichological, familial and social suport. Weight loss program must be carefully planned, adapted to the patient’s abilities and comorbidities and supervised by a nutritionist and a physiotherapist.

  19. [Treatment of compulsive buying].

    2008-08-01

    Although compulsive buying is receiving increasing attention in research, it is largely ignored in clinical practice. Compulsive buying disorder (CBD) is defined as excessive and mostly senseless spending or excessive shopping impulses that cause marked distress, interfere with social or occupational functioning, and often results in financial problems. It is currently conceptualized as an "impulse control disorder not otherwise specified" (ICD-10 F63.9). CBD is associated with significant psychiatric co-morbidity particularly mood and anxiety disorders, obsessive-compulsive disorders, binge eating disorder, substance use disorders, personality disorders, and other impulse control disorders. Previous research indicates that many compulsive buyers also suffer from compulsive hoarding. There is no evidence-based treatment approach for CBD and treatment research on this topic is limited. Open label trials suggest that antidepressants could improve compulsive buying. However, small randomized controlled trials failed to demonstrate significant improvement over Placebo and the high placebo-response rate prevents any definitive statement on the efficacy of antidepressants. Two controlled cognitive-behavioral therapy (CBT) trials reported that group CBT is significantly more effective compared to waiting list control groups in the treatment of compulsive buying. Clinical and therapeutic implications are discussed.

    This task involves the recovery of the liquid (supernatant or supernate) portions of Oak Ridge National Laboratory (ORNL) Melton Valley Storage Tank waste in a hot cell and treatment of the supernate to separate and remove the radionuclides. The supernate is utilized in testing various sorbent materials for removing cesium, strontium, and technetium from the highly alkaline, saline solutions. Batch tests are used to evaluate and select the most promising materials for supernate treatment to reduce the amount of waste for final disposal. Once the sorbents have been selected based on the results from the batch tests, small column tests are made to verify the batch data. Additional data from these tests can be used for process design. The sorption tests emphasize evaluation of newly developed sorbents and engineered forms of sorbents. Methods are also evaluated for recovering the radionuclides from the sorbents, including evaluating conditions for eluting ion exchange resins. A final report will summarize the results and compare the results with those of other investigators, along with recommendations for separating and concentrating radionuclides from DOE storage tank supernates at Oak Ridge and other sites. Documentation of the data and the significance of the findings will be compared, and recommendations will be provided to likely users of the data in EM-30. This program also provides input to the supernate treatment process demonstration projects at ORNL

    The pharmacological treatment of obesity should be considered when cannot be achieved a 10% weight loss with diet therapy and physical activity. The drugs effective in obesity treatment may act by different mechanisms such as reduction in food intake, inhibition of fat absorption, increase of thermogenesis and stimulation of adipocyte apoptosis. At present, we only have two marketed drugs for obesity treatment. Sibutramine is an inhibitor of norepinephrine, dopamine and serotonina reuptake which inhibits food intake and increases thermogenesis. Sibutramine administration for a year can induce a weight loss of 4-7%. Its main side effects are hypertension, headache, insomnia and constipation. Orlistat is an inhibitor of pancreatic lipase which is able to block the absorption of 30% of ingested fat. Its administration induces weight loss and reduction of ulterior weight regain. Also, this drug improves hypertension dyslipdaemia and helps to prevent diabetes in 52% of cases when administered over four years. The increase in frequency of stools and interference with vitamin absorption are its main side effects. Glucagon-like peptide 1, which increases insulin sensitivity and satiety, adiponectin and PPAR-gamma agonists which reduce insulin resistance and modulates adipocyte generation are the basis for future therapeutic approaches of obesity. Phosphatase inhibitors induce PPAR-gamma phosphorylation and UCP-1 expression leading to an increase in thermogenesis and reduction in appetite.

    The steam plant located at the Oak Ridge National Laboratory was converted from oil- to coal-fired boilers. In the process, a diked, 1.6-ha coal storage yard was constructed. The purpose of this report is to describe the treatment system designed to neutralize the estimated 18,000 m/sup 3/ of acidic runoff that will be produced each year. A literature review and laboratory treatability study were conducted which identified two treatment systems that will be employed to neutralize the acidic runoff. The first, a manually operated system, will be constructed at a cost of $200,000 and will operate for an interim period of four years. This system will provide for leachate neutralization until a more automated system can be brought on-line. The second, a fully automated system, is described and will be constructed at an estimated cost of $650,000. This automated runoff treatment system will ensure that drainage from the storage yard meets current National Pollutant Discharge Elimination System Standards for pH and total suspended solids, as well as future standards, which are likely to include several metals along with selected trace elements.

    Comprehensively review the evidence regarding the use of ayahuasca, an Amerindian medicine traditionally used to treat many different illnesses and diseases, to treat some types of cancer. An in-depth review of the literature was conducted using PubMed, books, institutional magazines, conferences and online texts in nonprofessional sources regarding the biomedical knowledge about ayahuasca in general with a specific focus in its possible relations to the treatment of cancer. At least nine case reports regarding the use of ayahuasca in the treatment of prostate, brain, ovarian, uterine, stomach, breast, and colon cancers were found. Several of these were considered improvements, one case was considered worse, and one case was rated as difficult to evaluate. A theoretical model is presented which explains these effects at the cellular, molecular, and psychosocial levels. Particular attention is given to ayahuasca's pharmacological effects through the activity of N,N-dimethyltryptamine at intracellular sigma-1 receptors. The effects of other components of ayahuasca, such as harmine, tetrahydroharmine, and harmaline, are also considered. The proposed model, based on the molecular and cellular biology of ayahuasca's known active components and the available clinical reports, suggests that these accounts may have consistent biological underpinnings. Further study of ayahuasca's possible antitumor effects is important because cancer patients continue to seek out this traditional medicine. Consequently, based on the social and anthropological observations of the use of this brew, suggestions are provided for further research into the safety and efficacy of ayahuasca as a possible medicinal aid in the treatment of cancer.

    Full Text Available The mystery of Traditional Chinese Medicine has been attracting people for years. Acupuncture, ranked among the most common services of Complementary and Alternative Medicine, has recently gained a lot of interest in the scientific world. Contemporary researchers have been continuously trying to shed light on its possible mechanism of action in human organism. Numerous studies pertaining to acupuncture’s application in cancer symptoms or treatment-related side effects management have already been published. Moreover, since the modern idea of acupuncture’s immunomodulating effect seems to be promising, scientists have propounded a concept of its potential application as part of direct anti-tumor therapy. In our previous study we summarized possible use of acupuncture in management of cancer symptoms and treatment-related ailments, such as chemotherapy-induced nausea and vomiting, pain, xerostomia, vasomotor symptoms, neutropenia, fatigue, anxiety, insomnia, lymphoedema after mastectomy and peripheral neuropathy. This article reviews the studies concerning acupuncture as a possible tool in modern anticancer treatment.

    This article discusses composition of chemical compounds dissolved or suspended in mine waters in various coal basins of the USSR: Moscow basin, Kuzbass, Pechora, Kizelovsk, Karaganda, Donetsk and Chelyabinsk basins. Percentage of suspended materials in water depending on water source (water from water drainage system of dust suppression system) is evaluated. Pollution of mine waters with oils and coli bacteria is also described. Recommendations on construction, capacity of water settling tanks, and methods of mine water treatment are presented. In mines where coal seams 2 m or thicker are mined a system of two settling tanks should be used: in the upper one large grains are settled, in the lower one finer grains. The upper tank should be large enough to store mine water discharged during one month, and the lower one to store water discharged over two months. Salty waters from coal mines mining thin coal seams should be treated in a system of water reservoirs from which water evaporates (if climatic conditions permit). Mine waters from mines with thin coal seams but without high salt content can be treated in a system of long channels with water plants, which increase amount of oxygen in treated water. System of biological treatment of waste waters from mine wash-houses and baths is also described. Influence of temperature, sunshine and season of the year on efficiency of mine water treatment is also assessed. (In Russian)

    1990-01-01

    Animal experiments have explored the structural and functional alterations of the afferent visual pathways in amblyopia and have emphasized the extraordinary sensitivity of the immature visual system to abnormal visual stimulation. The practical consequences of these experiments are obvious: early diagnosis of amblyopia and energetic occlusion therapy as early in life as possible. At the same time, measures must be taken to prevent visual deprivation amblyopia in the occluded eye. After successful treatment, alternating penalization with two pairs of spectacles is recommended. Pleoptics involves an enormous commitment in terms of time, personnel and costs. In view of the fact that the superiority of this treatment over occlusion therapy has yet to be proven, the current value of pleoptics appears dubious. Moreover, overtreated patients may end up with intractable diplopia. Diverging opinions exist with regard to the use of penalization as a primary treatment of amblyopia. We employ it only in special cases as an alternative to occlusion therapy. Visual deprivation in infancy caused by opacities of the ocular media, especially when they occur unilaterally, must be eliminated, and deprivation amblyopia must be treated without delay to regain useful vision. Brief periods of bilateral occlusion are recommended to avoid the highly amblyopiogenic imbalance between binocular afferent visual input. Future developments will hopefully include new objective methods to diagnose amblyopia in preverbal children and infants. The application of positron emission tomography is perhaps the first step in the direction of searching for new approaches to this problem.(ABSTRACT TRUNCATED AT 250 WORDS)

    Full Text Available Following the death of a loved one, a small group of grievers develop an abnormal grieving style, termed complicated or prolonged grief. In the effort to establish complicated grief as a disorder in DSM and ICD, several attempts have been made over the past two decades to establish symptom criteria for this form of grieving. Complicated grief is different from depression and PTSD yet often comorbid with other psychological disorders. Meta-analyses of grief interventions show small to medium effect sizes, with only few studies yielding large effect sizes. In this article, an integrative cognitive behavioral treatment manual for complicated grief disorder (CG-CBT of 25 individual sessions is described. Three treatment phases, each entailing several treatment strategies, allow patients to stabilize, explore, and confront the most painful aspects of the loss, and finally to integrate and transform their grief. Core aspects are cognitive restructuring and confrontation. Special attention is given to practical exercises. This article includes the case report of a woman whose daughter committed suicide.

    Few studies examined treatments for amphetamine withdrawal, although it is a common problem among amphetamine users. Its symptoms, in particular intense craving, may be a critical factor leading to relapse to amphetamine use. In clinical practice, medications for cocaine withdrawal are commonly used to manage amphetamine withdrawal although the pharmacodynamic and pharmacokinetic properties of these two illicit substances are different. To assess the effectiveness of pharmacological alone or in combination with psychosocial treatment for amphetamine withdrawals on discontinuation rates, global state, withdrawal symptoms, craving, and other outcomes. MEDLINE (1966 - 2008), CINAHL (1982 - 2008), PsycINFO (1806 - 2008), CENTRAL (Cochrane Library 2008 issue 2), references of obtained articles. All randomised controlled and clinical trials evaluating pharmacological and or psychosocial treatments (alone or combined) for people with amphetamine withdrawal symptoms. Two authors evaluated and extracted data independently. The data were extracted from intention-to-treat analyses. The Relative Risk (RR) with the 95% confidence interval (95% CI) was used to assess dichotomous outcomes. The Weighted Mean Difference (WMD) with 95% CI was used to assess continuous outcomes. Four randomised controlled trials (involving 125 participants) met the inclusion criteria for the review. Two studies found that amineptine significantly reduced discontinuation rates and improved overall clinical presentation, but did not reduce withdrawal symptoms or craving compared to placebo. The benefits of mirtazapine over placebo for reducing amphetamine withdrawal symptoms were not as clear. One study suggested that mirtazapine may reduce hyperarousal and anxiety symptoms associated with amphetamine withdrawal. A more recent study failed to find any benefit of mirtazapine over placebo on retention or on amphetamine withdrawal symptoms. No medication is effective for treatment of amphetamine

    2016-02-01

    Despite numerous case reports, the evidence for treatment of bruxism is still low. Different treatment modalities (behavioral techniques, intraoral devices, medications, and contingent electrical stimulation) have been applied. A clinical evaluation is needed to differentiate between awake bruxism and sleep bruxism and rule out any medical disorder or medication that could be behind its appearance (secondary bruxism). A polysomnography is required only in a few cases of sleep bruxism, mostly when sleep comorbidities are present. Counselling with regard to sleep hygiene, sleep habit modification, and relaxation techniques has been suggested as the first step in the therapeutic intervention, and is generally considered not harmful, despite low evidence of any efficacy. Occlusal splints are successful in the prevention of dental damage and grinding sounds associated with sleep bruxism, but their effects on reducing bruxism electromyographic (EMG) events are transient. In patients with psychiatric and sleep comorbidities, the acute use of clonazepam at night has been reported to improve sleep bruxism, but in the absence of double-blind randomized trials, its use in general clinical practice cannot be recommended. Severe secondary bruxism interfering with speaking, chewing, or swallowing has been reported in patients with neurological disorders such as in cranial dystonia; in these patients, injections of botulinum toxin in the masticatory muscles may decrease bruxism for up to 1-5 months and improve pain and mandibular functions. Long-term studies in larger and better specified samples of patients with bruxism, comparing the effects of different therapeutic modalities on bruxism EMG activity, progression of dental wear, and orofacial pain are current gaps of knowledge and preclude the development of severity-based treatment guidelines.

  13. Treatment of Alzheimer disease.

    Winslow, Bradford T; Onysko, Mary K; Stob, Christian M; Hazlewood, Kathleen A

    2011-06-15

    Alzheimer disease is the most common form of dementia, affecting nearly one-half [corrected] of Americans older than 85 years. It is characterized by progressive memory loss and cognitive decline. Amyloid plaque accumulation, neurofibrillary tau tangles, and depletion of acetylcholine are among the pathologic manifestations of Alzheimer disease. Although there are no proven modalities for preventing Alzheimer disease, hypertension treatment, omega-3 fatty acid supplementation, physical activity, and cognitive engagement demonstrate modest potential. Acetylcholinesterase inhibitors are first-line medications for the treatment of Alzheimer disease, and are associated with mild improvements in cognitive function, behavior, and activities of daily living; however, the clinical relevance of these effects is unclear. The most common adverse effects of acetylcholinesterase inhibitors are nausea, vomiting, diarrhea, dizziness, confusion, and cardiac arrhythmias. Short-term use of the N-methyl-D-aspartate receptor antagonist memantine can modestly improve measures of cognition, behavior, and activities of daily living in patients with moderate to severe Alzheimer disease. Memantine can also be used in combination with acetylcholinesterase inhibitors. Memantine is generally well tolerated, but whether its benefits produce clinically meaningful improvement is controversial. Although N-methyl-D-aspartate receptor antagonists and acetylcholinesterase inhibitors can slow the progression of Alzheimer disease, no pharmacologic agents can reverse the progression. Atypical antipsychotics can improve some behavioral symptoms, but have been associated with increased mortality rates in older patients with dementia. There is conflicting evidence about the benefit of selegiline, testosterone, and ginkgo for the treatment of Alzheimer disease. There is no evidence supporting the beneficial effects of vitamin E, estrogen, or nonsteroidal anti-inflammatory drug therapy.

    A tragic burden of disease, disability, and death has resulted from smoking. The role of pulmonary rehabilitation is not only in treatment and rehabilitation of lung disease but in the prevention of lung disease. The skills of the pulmonary rehabilitation specialist should be used in the earlier detection and prevention of lung disease through primary and secondary prevention. The spirometer must gain acceptance in the medical community as the early tool to evaluate lung health, not the chest radiograph or the stethoscope. The lung age formula and sputum pap smears are just a few of the evaluation tools used to detect and motivate susceptible individuals. Prevention is the key to enhancing lung health.

    Electrohydraulic treatment was applied to suspensions of Escherichia coli, spores of Bacillus subtilis var. niger, Saccharomyces cerevisiae, and bacteriophage T2 at an input energy that, in most cases, was below the energy required to sterilize. The input energy was held relatively constant for each of these microorganisms, but the capacitance and voltage were varied. Data are presented which show the degree of disinfection as a function of capacitance and voltage. In all cases, the degree of disinfection for a given input energy increases as both capacitance and voltage are lowered.

    For several years the French Atomic Energy Commission has been studying with interest problems presented by radio-active effluents. Since high activities have not yet received a definite solution we will deal only, in this paper, with the achievements and research concerning low and medium activity effluents. In the field of the achievements, we may mention the various effluent treatment stations which have been built in France; a brief list will be given together with an outline of their main new features. Thus in particular the latest treatment stations put into operation (Grenoble, Fontenay-aux-Roses, Cadarache) will be presented. From all these recent achievements three subjects will be dealt with in more detail. 1 - The workshop for treating with bitumen the sludge obtained after concentration of radionuclides. 2 - The workshop for treating radioactive solid waste by incineration. 3 - A unit for concentrating radio-active liquid effluents by evaporation. In the field of research, several topics have been undertaken, a list will be given. In most cases the research concerns the concentration of radionuclides with a view to a practical and low cost storage, a concentration involving an efficient decontamination of the aqueous liquids in the best possible economic conditions. For improving the treatments leading to the concentration of nuclides, our research has naturally been concerned with perfecting the treatments used in France: coprecipitation and evaporation. In our work we have taken into account in particular two conditions laid down in the French Centres. 1 - A very strict sorting out of the effluents at their source in order to limit in each category the volume of liquid to be dealt with. 2 - The necessity for a very complete decontamination due to the high population density in our country. In the last past we present two original methods for treating liquid effluents. 1 - The use of ion-exchange resins for liquids containing relatively many salts. The

    Antipsychotics play a key role in biologic therapy of schizophrenia. Following the first-generation neuroleptics, associated with many extrapyramidal side effects (severe dystonias, parkinsonian syndrome, akatisia and late dyskinesia) altering patients' compliance to the treatment, one can now find a new generation of molecules considered as atypical antipsychotics because they rarely cause neurological complications. This propriety provides a better compliance, along with a clear decrease of late dyskinesia risk but the effectiveness compared to ordinary molecules is still questioned. However, some of them can cause an increased risk of metabolic syndrome. Some molecules such as benzodiazepines and some antidepressants can also be prescribed to cure schizophrenic patients.

    1995-08-01

    Amyloidosis is the extracellular deposition of normally soluble autologous protein in a characteristic abnormal fibrillar form. Systemic amyloidosis and some local forms are progressive, cause major morbidity, and are often fatal. No treatment specifically causes the resolution of amyloid deposits, but therapy that reduces the supply of amyloid fibril precursor proteins can improve survival and preserve organ function. Major regression of amyloid occurs in at least a proportion of such cases, suggesting that the clinical improvement reflects mobilization of amyloid. The clearest evidence for regression of amyloid has been obtained in juvenile rheumatoid arthritis patients with AA amyloidosis treated with chlorambucil. This drug suppresses the acute phase production of serum amyloid A protein, the precursor of AA amyloid fibrils, and is associated with remission of proteinuria and greatly improved survival. In many such patients, scintigraphy with serum amyloid P component shows major regression of amyloid over 12 to 36 months and frequently reveals a discrepancy between the local amyloid load and organ dysfunction. Measurement of target organ function is therefore not an adequate method for monitoring treatment aimed at promoting the resolution of amyloid. In monoclonal immunoglobulin light chain (AL) amyloidosis the aim of treatment is to suppress the underlying B-cell clone and, therefore, production of the amyloid fibril precursor protein. This can be difficult to achieve or sustain and, since the prognosis is so poor, many patients die before benefits of therapy are realized. A recent development has been the introduction of liver transplantation as treatment for familial amyloid polyneuropathy caused by transthyretin gene mutations. This leads to the disappearance of variant transthyretin from the plasma and halts progression of the neurologic disease. Features of autonomic neuropathy frequently ameliorate, and improvement in peripheral motor nerve function

    A furnace heats through both infrared radiation and convective air utilizing an infrared/purge gas design that enables improved temperature control to enable more uniform treatment of workpieces. The furnace utilizes lamps, the electrical end connections of which are located in an enclosure outside the furnace chamber, with the lamps extending into the furnace chamber through openings in the wall of the chamber. The enclosure is purged with gas, which gas flows from the enclosure into the furnace chamber via the openings in the wall of the chamber so that the gas flows above and around the lamps and is heated to form a convective mechanism in heating parts.

    The increased prevalence of adolescent obesity and associated short-term and long-term complications emphasize the need for effective treatment. In this Review, we aim to describe the evidence for, and elements of, behaviour management and adjunctive therapies and highlight the opportunities and challenges presented by obesity management in adolescence. The broad principles of treatment include management of obesity-associated complications; a developmentally appropriate approach; long-term behaviour modification (dietary change, increased physical activity, decreased sedentary behaviours and improved sleep patterns); long-term weight maintenance strategies; and consideration of the use of pharmacotherapy, more intensive dietary therapies and bariatric surgery. Bariatric surgery should be considered in those with severe obesity and be undertaken by skilled bariatric surgeons affiliated with teams experienced in the medical and psychosocial management of adolescents. Adolescent obesity management strategies are more reliant on active participation than those for childhood obesity and should recognize the emerging autonomy of the patient. The challenges in adolescent obesity relate primarily to the often competing demands of developing autonomy and not yet having attained neurocognitive maturity.

    Full Text Available The fast global increased prevalence of obesity has been classifiedas an epidemics by the World Health Organization. The etiology ofobesity is very complex and involves genetic and environmentalfactors. One of the main factors that trigger obesity is sedentarylife, as well as the great availability of fat-rich foods that present ahigh energy density. According to the NHANES II, although thepopulation has decreased the ingestion of fat, the total consumptionof food has increased. The main factors that influence in choice offood are flavor, followed by cost, convenience and, finally, itsnutritional value. The dietary treatment of obesity should haverealistic goals concerning weight loss rate and amount. It issuggested to prescribe a balanced low-calorie diet, emphasizingmostly the quality of foods by using the food pyramid. Therefore,patients may learn the appropriate criteria to select food and makehealthy choices. The dietary treatment of obesity also includesthe use of behavioral techniques directed at dietary education,thus resulting in choice of healthy foods with adequate energyvalue.

    Full Text Available In this thesis, our purpose is to show that using physiotherapy on patients with hip dysplasia from the very beginning, in the first months of life, helps treating them faster. Common literature proposes to use physiotherapy on patients with hip dysplasia either after their recovery or in the terminal phase of recovery, claiming that any earlier intervention will prolong the hip recovery. The effects of hip dysplasia reflect over the whole musculoskeletal system, while it hinders the knees (genu valgum, the ankles (ankle valgus, calcaneal valgus and the spine (scoliosis especially at the lumbar level. The most spectacular are at the hip level, that is why we made an analytical evaluation only for this joint. To show the importance of physiotherapy for children with hip dysplasia we started from the hypothesis: untimely treatment for children with hip dysplasia has improved results in functional recovery and in obtaining a better stability, without the necessity of orthopedics or surgical interventions. The research methods used in this study are: the observation method, the bibliographic study method, the experimental method, the graphics method and the statistical mathematical method to process the data and to represent the results graphically. In the end, the results obtained are significantly different from the initial evaluations and we came to the conclusion that starting an untimely analytical kinetic treatment and globally personalizing it to every patient improves stability and biomechanical parameters for the hip.

  10. Achalasia: Treatment Options Revisited

    Full Text Available The aim of all current forms of treatment of achalasia is to enable the patient to eat without disabling symptoms such as dysphagia, regurgitation, coughing or choking. Historically, this has been accomplished by mechanical disruption of the lower esophageal sphincter fibres, either by means of pneumatic dilation (PD or by open surgical myotomy. The addition of laparoscopic myotomy and botulinum toxin (BTX injection to the therapeutic armamentarium has triggered a recent series of reviews to determine the optimal therapeutic approach. Both PD and BTX have excellent short term (less than three months efficacy in the majority of patients. New data have been published that suggest that PD and BTX (with repeat injections can potentially obtain long term efficacy. PD is still considered the first-line treatment by most physicians; its main disadvantage is risk of perforation. BTX injection is evolving as an excellent, safe option for patients who are considered high risk for more invasive procedures. Laparoscopic myotomy with combined antireflux surgery is an increasingly attractive option in younger patients with achalasia, but long term follow-up studies are required to establish its efficacy and the potential for reflux-related sequelae.

    Full Text Available Great population studies do not confirm the hypothesis that atypical personality of obese would exist. Obeses in the generalpopulation do not present more psychological disturbs thanthe ones that are not obeses. Obeses adolescents and adultsare discriminated in their academic and professional lifes. Thissocial, cultural, economic and affective impoverishment seemsto be directly related to the gravity of their obesity, what means,higher the ICM (Index of Corporal Mass, bigger are thepsychological problems. This abandonment contributes to thebig risk of unchain psychiatric pictures as depression, anxyetdisturbs, drugs and alcoholic excessive consumption andalimentary disturbs. Obeses of the general population do notpresent more psychological or psychiatric symptoms than theclinical population of obeses (obeses under treatment, presentmore clinical and psychiatric problems, mainly compulsoryalimentary standards. Some studies indicate that there is alinear relation between the ICM and the highest frequency ofalimentary compulsory behavior or bulimic episode. Thepsychiatric patients negative body perception added to theirother negative perceptions about their performance in searchingsocial interaction increase the trend to the isolation. Thepsychiatric picture presence in the bariatric surgery preoperatoryin a III degree overweight pacient has not to be facedas absolute surgery counter indication since such procedurecan be the difference between giving a better life quality orwaiting for a potentially lethal complication. We cannot forgetthat the obesity itself, due to the common associatedcomorbidyties, loads a great lethality potential. The surgerycounter-indication could be relative, it depending on how muchthe psychiatric disturbs interfere on the treatment andconditioned to the rigorous psychiatric control in the anteriorand post surgical period.

    In Italy, environmental protection and energy conservation have become very important since the increase in oil prices. The law requires that all waste waters have a B.O.D. of 40 mg/l by 1986 so there has been an expansion of purification plants since 1976, using anaerobic digestion. The report deals with the current state of anaerobic treatment in Italy with particular reference to (1) animal wastes. In intensive holdings, anaerobic digestion leads to a decrease in pollution and an increase in biogas generation which can be used to cover the energy demand of the process. The factors which influence the builders of digestors for farms are considered. (2) Non toxic industrial wastes. These are the waste waters emanating from the meat packing, brewing, pharmaceutical and chemical industries. Particular reference is made to the distillery plants using anaerobic treatment prior to aerobic digestion. (3) Urban wastes. The advantages and the disadvantages are considered and further research and development is recommended. 20 references.

    The purpose of this paper is to analyze the current evolutions on nanotechnology and its applications on cancer theragnostics.Rapid advances and emerging technologies in nanotechnology are having a profound impact on cancer treatment. Applications of nanotechnology, which include liposomes, nanoparticles, polymeric micelles, dendrimers, nanocantilever, carbon nanotubes and quantum dots have significantly revolutionized cancer theragnostics. From a pharmaceutical viewpoint, it is critical that the biodistribution of active agents has to be controlled as much as possible. This aspect is vital in order to assure the proper efficiency and safety of the anticancer agents. These biocompatible nanocomposites provide specific biochemical interactions with receptors expressed on the surface of cancer cells. With passive or active targeting strategies, an increased intracellular concentration of drugs can be achieved in cancer cells , while normal cells are being protected from the drug simultaneously. Thus, nanotechnology restricts the extent of the adverse effects of the anticancer therapy. Treatment for metastatic breast cancer, sarcoma in AIDS patients, ovarian and lung cancer is already on market or under final phases of many clinical trials, showing remarkable results. As nanotechnology is perfected, side effects due to normal cell damage will decrease, leading to better results and lengthening patient's survival.

    In 1995-96 we selected a group of 26 patients who were suffering from severe invalidating idiopathic tinnitus (IT) in order to evaluate the efficacy of rehabilitation and some alternative therapies. All patients were assessed thoroughly by means of audiology and radiology regarding any objective cause for the symptom. In order to help patients control their symptom by increasing knowledge and adding supportive elements, they were given basic education (presentations of the anatomy and physiology of the ear and hearing system, psychological and social aspects of IT, guided and non-guided group discussions, relaxation therapy, physiotherapy, music therapy) for 4 months, comprising one 2-h session bi-weekly. This type of group therapy was found to be extremely helpful, although no objective evaluation revealed effects on IT sensation (VAS) or psychometric measures (SLC-90). In a second limb of the study, the same patients attended a 6-day intensive course in a spa. The purpose was to evaluate the possible usefulness of the widely recommended alternative therapies for IT. All patients had an opportunity to sample the treatments. Six months later only a few had tried any of these treatments, but all reported that the lessons were the most helpful in association with supportive group discussions. The results indicated that none of these therapies can be recommended, based on rational medical practise.

    Tourette's syndrome (TS) consists of chronic motor and phonic tics and characteristically begins in childhood. The tics can be disabling and commonly associated behavioral comorbities such as attention deficit hyperactivity disorder (ADHD) and obsessive-compulsive disorder (OCD), can also cause problems in daily functioning. The underlying etiology and neurobiology of TS remain unknown although genetic factors appear to be important, cortical control of basal ganglia motor function appears to be disturbed and neurochemical abnormalities, particularly involving dopamine neurotransmission, are likely present. The treatment of TS involves appropriate education and support. Tics can be treated with habit reversal cognitive behavioral therapy, medications (most commonly alpha agonists and antipsychotics), local intramuscular injections of botulinum toxin and some severe, refractory cases have responded to deep brain stimulation surgery (DBS). It is important to appropriately diagnose and treat comorbid behavioral disorders that are disrupting function. OCD can be treated with cognitive behavioral therapy, selective serotonin reuptake inhibitors, and atypical antipsychotics. DBS has become a treatment option for patients with disabling OCD despite other therapies. ADHD is treated with appropriate classroom accommodations, behavioral therapy, alpha agonists, atomoxetine or methylphenidate-containing stimulant drugs.
