    Full Text Available Abstract Background Angiotensin II receptor blockers (ARBs, including olmesartan and candesartan, are widely used antihypertensive agents. Many clinical studies have demonstrated that ARBs have organ-protecting effects, e.g., cardioprotection, vasculoprotection and renoprotection. However, the effect of prolonged olmesartan monotherapy on lipid metabolism in patients with hypertension is less well studied. We performed a retrospective observational study to compare the effects of olmesartan with those of candesartan, focusing on lipid metabolism and renal function. Methods We used data from the Clinical Data Warehouse of Nihon University School of Medicine obtained between Nov 1, 2004 and Feb 28, 2011, to identify cohorts of new olmesartan users (n = 168 and candesartan users (n = 266. We used propensity-score weighting to adjust for differences in all covariates (age, sex, comorbid diseases, previous drugs between olmesartan and candesartan users, and compared serum chemical data including serum triglyceride (TG, LDL-cholesterol (LDL-C, total cholesterol (TC, potassium, creatinine and urea nitrogen. The mean exposure of olmesartan and candesartan users was 126.1 and 122.8 days, respectively. Results After adjustment, there were no statistically significant differences in all covariates between olmesartan and candesartan users. The mean age was 60.7 and 61.0 years, and 33.4% and 33.7% of olmesartan and candesartan users were women, respectively. There were no statistically significant differences in mean values for all laboratory tests between baseline and during the exposure period in both olmesartan and candesartan users. In olmesartan users, the reduction of serum TG level was significant in comparison with that in candesartan users. Other parameters of lipid profile and renal function showed no statistically significant difference in the change from baseline to during the exposure period between olmesartan and candesartan users.

    Two bioavailability/bioequivalence studies were carried out to evaluate the pharmacokinetics of candesartan cilexetil 16-mg tablet formulations. A pilot study was used to optimize the formulation and manufacturing process prior to conducting the definitive study. The pilot study was a single-dose, randomized, 2-period crossover, and the definitive study was a single-dose, randomized, 3-period, 6-sequence crossover study in healthy adults. In the pilot study the test formulation was 24% and 18% greater for Cmax and AUC, respectively, compared with the innovator product. Following optimization two 16-mg candesartan cilexetil tablet formulations were taken forward into the second bioavailability study.  Eighteen healthy fasted adult subjects were dosed with either the test formulations or the innovator. The pharmacokinetic parameters Cmax , AUC0-t , and AUC0-∞ of candesartan were investigated together with safety and tolerability. The geometric mean ratios (GMRs) and 90% confidence intervals (CIs) for candesartan, Cmax , AUC0-t , and AUC0-∞ were within the boundary of 0.8-1.25 for one of the test formulations (formulation 2). For test formulation 3 the 90%CI of GMR for Cmax was above (133%) the upper limit of 125% for bioequivalence. Test formulation 2 was found to be bioequivalent and met internationally acceptable regulatory requirements.

    The objective of the present investigation was to enhance the oral bioavailability of practically insoluble Candesartan cilexetil [CC] by preparing nanosuspension. The nanosuspension was prepared by media milling using zirconium oxide beads and converted to solid state by spray drying. The spray dried nanosuspension of CC [SDCN] was evaluated for particle size, zeta potential, saturation solubility, crystallanity, surface morphology and dissolution behavior. SDCN showed particle size of 223.5±5.4 nm and zeta potential of -32.2±0.6 mV while saturation solubility of bulk CC and SDCN were 125±6.9 μg/ml and 2805±29.5 μg/ml respectively, showing more than 20 times increase in solubility. Differential Scanning Calorimetry [DSC] and X-ray diffraction [XRD] analysis showed that crystalline state of CC remained unchanged in SDCN. Dissolution studies in phosphate buffer pH 6.5 containing 0.7% Tween 20 showed that 53±5% of bulk drug dissolved in 15 min whereas SDCN was almost completely dissolved exhibiting higher dissolution velocity and solubility. Transmission electron microscopy [TEM] revealed that nanocrystals were not of uniform size, and approximately of oval shape. Pharmacodynamic study based on deoxycorticosterone acetate [DOCA] salt model was performed in rats to evaluate in-vivo performance, which showed 26.75±0.33% decrease in systolic blood pressure for nanosuspension while plain drug suspension showed 16.0±0.38% reduction, indicating that increase in dissolution velocity and saturation solubility leads to enhancement of bioavailability of SDCN when compared to bulk CC suspension. Thus, the results conclusively demonstrated a significant enhancement in antihypertensive activity of candesartan when formulated as nanosuspension.

    The historical evolving examples of the confirmation of therapeutic efficacy of some Chinese materia medica, the social fashion of using medicine, and the processing methods of Chinese materia medica indicate that the social trend of thoughts, customs and economic factors in different ages affected the various aspects of Chinese materia medica. So, Chinese materia medica possesses very outstanding social and cultural features. Not all the actions of Chinese materia medica recorded came from the experiences of doctors. The understanding level to the nature in different ages decides what kind of drugs they would accept. There are three kinds of drug processing in ancient times: effective medicinal processing, fantastic Taoist processing and invalid trading processing. Based on the study of sociocultural history of therapeutic efficacy and processing of Chinese materia medica. It is crucial that the history and medical literature research on Chinese materia medica and pharmacy should be raised to the position as important as clinical and experiment researches.

    Hypertrophic cardiomyopathy is caused by mutations in the genes that encode sarcomeric proteins and is primarily characterized by unexplained left ventricular hypertrophy, impaired cardiac function, reduced exercise tolerance, and a relatively high incidence of sudden cardiac death, especially in the young. The extent of left ventricular hypertrophy is one of the major determinants of disease prognosis. Angiotensin II has trophic effects on the heart and plays an important role in the development of myocardial hypertrophy. Here in a double-blind, placebo-controlled, randomized study, we show that the long-term administration of the angiotensin II type 1 receptor antagonist candesartan in patients with hypertrophic cardiomyopathy was associated with the significant regression of left ventricular hypertrophy, improvement of left ventricular function, and exercise tolerance. The magnitude of the treatment effect was dependent on specific sarcomeric protein gene mutations that had the greatest responses on the carriers of ss-myosin heavy chain and cardiac myosin binding protein C gene mutations. These data indicate that modulating the role of angiotensin II in the development of hypertrophy is specific with respect to both the affected sarcomeric protein gene and the affected codon within that gene. Thus, angiotensin II type 1 receptor blockade has the potential to attenuate myocardial hypertrophy and may, therefore, provide a new treatment option to prevent sudden cardiac death in patients with hypertrophic cardiomyopathy.

    Full Text Available The present research work was aimed at the enhancement of solubility of Candesartan by Self Emulsifying Drug Delivery Systems (SEDDS. Candesartan is a BCS class II drug having low aqueous solubility and high permeability; hence its bioavailability is solubility rate limited. The saturated solubility of Candesartan in various oils and surfactants was determined. The excipients were screened and selected showing maximum solubility and compatibility for Candesartan. SEDDS formulations of Candesartan were developed using different Oils, Surfactants and Co-Surfactant combinations. Pseudoternary phase diagrams were constructed using Triplot V 4.1.2 software and applying Pseudoternary phase diagrams, microemulsification area was evaluated. Formulations were prepared based on phase diagrams using various proportions of oil, surfactants and co-surfactants. The formulations were screened visually for stability and phase separation. Seven formulations were selected for further evaluations like effect of dilution, freeze-thawing, emulsion droplet size and zeta potential. Among the seven formulations three were optimized and filled in hard gelatin capsules. The in-vitro dissolution studies of the SEDDS formulation were performed and the dissolution rate of SEDDS was compared with plain Candesartan (API. The results indicated that the solubility and dissolution rate of Candesartan was significantly higher than that of plain drug (API. The results of the present studies demonstrate that SEDDS can be used as a potential means for improving solubility, dissolution and bioavailability of Candesartan.

    Metabonomics, a newly developing subject secondary to genomics, transcriptomics, and proteomics, is an important constituent part of systems biology. It is believed to be the final direction of the systems biology. It can be directly applied to understand the physiological and biochemical states by its "metabolome profile" as a whole. Therefore, it can provide a huge amount of information different from those originating from other "omics". In the modernization of Chinese materia medica research, the application of metabonomics methods and technologies has a broad potential for future development. Especially it is of important theoretical significance and application value in holistic efficacies evaluation, active ingredients studies, and safety research of Chinese materia medica.

    Full Text Available Candesartan Cilexetil is an esterified prodrug of Candesartan, a non-peptide angiotensin II type-1(AT1 receptor antagonist used in the treatment of hypertension and congestive heart failure. Candesartan meets the requirement of high potency but it is poorly absorbed when administered orally. Therefore, the prodrug Candesartan Cilexetil is developed. It is soluble in methylene chloride, half life is 5.1 to 10.5hrs and bioavailability is 15%. It is marketed as conventional tablets. In this work, it is formulated as immediate release tablets by changing the concentration of ingredients. For many drug substances, conventional immediate-release formulations provide clinically effective therapy while maintaining the required balance of pharmacokinetic and pharmacodynamic profiles with in acceptable level of safety to the patient. The immediate release formulation of Candesartan Cilexetil is prepared by wet granulation method to provide rapid onset of action. In order to optimize the best formulation, ten different trials are developed. The main ingredients used in the formulation are lactose monohydrate, PEG, calcium CMC and MCC. Weight variation, thickness, friability, disintegration time, in-vitro release, pharmaceutical assay are studied as response variables. The formulation containing 38% of MCC is selected as an optimized product in which the different physical properties and in-vitro release profile showed best comparable results with innovator product.

    Full Text Available Pedanius Dioscorides was a Roman army surgeon in the first century A.D. His great work called De Materia Medica is widely accepted as the foremost pharmaceutical source of antiquity. Dioscorides was the originator of materia medica (pharmacology, and he took advantage of his extensive travels to study plants. Dioscorides was considered a major authority on simple drugs for sixteen centuries. De Materia Medica served as a corner stone for both western and eastern pharmaceutical and herbal writing, and was translated into Syriac, Arabic, and Persian, as well as Latin. The particular characteristic of medical therapy in the Medieval Period was the extensive employment of drugs of all kinds. For this reason, Dioscorides’ De Materia Medicawas not only studied closely, but it also became a text book that Turk-Islamic scientists frequently referred to in their writings.Pedanius Dioscórides fue médico cirujano en el ejército romano en el siglo I d.C. Su gran obra llamada De Materia Medica es conocida como la principal fuente de farmacopea de la antigüedad. Dioscórides fue el inventor de la materia medica, y aprovechó sus extensos viajes para dedicarse al estudio de las plantas. Dioscórides fue considerado una eminencia en el tema de las drogas de origen natural a lo largo de dieciséis siglos. De Materia Medica sirvió como piedra angular para los textos farmacéuticos y herbarios tanto en occidente como en oriente y fue traducida al siríaco, árabe y persa, además de al latín. La particular característica de la terapia médica en la época medieval fue el uso extensivo de todo tipo de drogas. Por esta razón, además de estudiarse minuciosamente, De Materia Medica de Dioscórides se convirtió también en un libro de texto al que frecuentemente hacían referencia los científicos turco-islámicos en sus escrituras.

    Non steroidal anti-inflammatory drugs (NSAIDs) induce gastric mucosal lesions in part by induction of oxidative stress as well as the activation of inflammatory cells and the production of proinflammatory cytokines. In this study, we examined the protective effect of candesartan (2 and 5 mg/kg) on indomethacin-induced gastric mucosa damage. Pretreatment with candesartan for 10 days reduced significantly the ulcer index induced by indomethacin injection. The preventive index of 2 mg/kg (76.74%) was higher than that of 5 mg/kg (65.11%). Both doses of candesartan were able to reduce significantly the stomach malondialdehyde content compared to indomethacin-treated group. Myeloperoxidase, tumor necrosis factor-α, cytokine-induced neutrophil chemoattractant gastric levels were significantly reduced by 2 mg/kg of candesartan more than 5 mg/kg. The Th1 cytokine interferon γ was also significantly reduced by both doses of candesartan compared to indomethacin injected group. On the other hand, indomethacin significant decreased the anti-inflammatory cytokine IL-10 gastric level. Pretreatment with candesartan (2 and 5 mg/kg) reversed this effect. In conclusion, the present study indicates that pretreatment with candesartan, can protect against the stomach injury induced by indomethacin through its antioxidant and immunomodulatory effects.

    A review of "up to date" research findings leading to new concepts of the pharmaceutical formulations and their interactions has been presented. The rational approaches to the excipients choice as well as to their interactions with medicaments have been shown as a basis for modern modelling of pharmaceutical formulations. The importance of complexation, hydrogen bonding, ion-dipole, dipole-dipole and van der Waals attractions as the tools which can modify the physicochemical, pharmacological or pharmacokinetical behaviour of the medicaments has been emphasised. In vivo studies (carried out in healthy human subjects-volunteers, in beagle dogs, in rats etc.) and in vitro studies (on excised human skin, hairless mouse skin etc.) as well as studies of chemical stability and bioavailability serve also as a proof of these interactions. Therefore, excipients are important components of pharmaceutical formulations and they can take an active part in the improvement of the characteristics of formulations (but they may also reduce the effectiveness of some preparations). In this context, the so called active and inactive ingredients in pharmaceutical formulations are inexact, old and "out-of date". Their further use is only conventional. In conclusion, among the various modern techniques applied the combination of infrared spectroscopy and X-ray diffraction has been estimated as the most successful in proving the interactions between drugs and excipients. Finally, pharmaceutical formulations and their interactions have constituted a diverse and rapidly expanding field of Pharmacy (Pharmaceutical Technology, Pharmaceutical Industry and Pharmaceutical Sciences) which covers a wide range of numerical topics within an unified framework.

    Full Text Available Several studies indicate that blockade of the renin-angiotensin-aldosterone system (RAAS can prevent atherosclerosis and vascular events, but the precise mechanisms involved are still unclear. In this study, we investigated the effect of the AT 1-receptor blocker, candesartan, in the prevention of atherosclerosis in Watanabe heritable hyperlipidaemic (WHHL rabbits and also the effect of AT1-receptor blockade in the uptake of oxidised LDL by macrophage cell cultures. In the first set of experiments, 12 WHHL rabbits were randomly assigned to three groups: placebo, atenolol 5 mg/kg daily or candesartan 2 mg/kg daily for six months. Compared with controls and atenolol-treated rabbits, candesartan treatment resulted in a significant 50—60% reduction of atherosclerotic plaque formation and a 66% reduction in cholesterol accumulation in the thoracic aorta.Studies in macrophage cultures indicated that candesartan prevented uptake of oxidised LDL-(oxLDL-cholesterol by cultured macrophages. Candesartan inhibited the uptake of oxLDL in a dose-dependent manner, reaching a maximum inhibition of 70% at concentrations of 5.6 µg/ml. Further studies in other animal models and well-designed trials in humans are warranted to further explore the role of AT1-receptor blockade in the prevention of atherosclerosis.

    A validated ultra-performance liquid chromatography mass spectrometric method (UPLC-MS/MS) was used for the simultaneous quantitation of candesartan (CN) and hydrochlorothiazide (HCT) in human plasma. The analysis was performed on UPLC-MS/MS system using turbo ion spray interface. Negative ions were measured in multiple reaction monitoring (MRM) mode. The analytes were extracted using a liquid-liquid extraction (LLE) method by using 0.1 mL of plasma volume. The lower limit of quantitation for CN and HCT was 1.00 ng/mL whereas the upper limit of quantitation was 499.15 ng/mL and 601.61 ng/mL for CN and HCT respectively. CN d4 and HCT-13Cd2 were used as the internal standards for CN and HCT respectively. The chromatography was achieved within 2.0 min run time using a C18 Pheno-menex, Gemini NX (100 mm ~ 4.6 mm, 5 mm) column with organic mixture:buffer solution (80:20, v/v) at a flow rate of 0.800 mL/min. The method has been successfully applied to establish the bioequivalence of candesartan cilexetil (CNC) and HCT immediate release tablets with reference product in human subjects.

    Full Text Available Inherited dilated cardiomyopathy (DCM is characterized by dilatation and dysfunction of the ventricles, and often results in sudden death or heart failure (HF. Although angiotensin receptor blockers (ARBs have been used for the treatment of HF, little is known about the effects on postulated electrical remodeling that occurs in inherited DCM. The aim of this study was to examine the effects of candesartan, one of the ARBs, on cardiac function and electrical remodeling in the hearts of inherited DCM model mice (TNNT2 ΔK210. DCM mice were treated with candesartan in drinking water for 2 months from 1 month of age. Control, non-treated DCM mice showed an enlargement of the heart with prolongation of QRS and QT intervals, and died at t1/2 of 70 days. Candesartan dramatically extended the lifespan of DCM mice, suppressed cardiac dilatation, and improved the functional parameters of the myocardium. It also greatly suppressed prolongation of QRS and QT intervals and action potential duration (APD in the left ventricular myocardium and occurrence of ventricular arrhythmia. Expression analysis revealed that down-regulation of Kv4.2 (Ito channel protein, KChIP2 (auxiliary subunit of Kv4.2, and Kv1.5 (IKur channel protein in DCM was partially reversed by candesartan administration. Interestingly, non-treated DCM heart had both normal-sized myocytes with moderately decreased Ito and IKur and enlarged cells with greatly reduced K+ currents (Ito, IKur IK1 and Iss. Treatment with candesartan completely abrogated the emergence of the enlarged cells but did not reverse the Ito, and IKur in normal-sized cells in DCM hearts. Our results indicate that candesartan treatment suppresses structural remodeling to prevent severe electrical remodeling in inherited DCM.

  8. What has been overlooked on study of Chinese materia medica in the West?

    Chinese materia medica (CMM), including Chinese herbal, animal, and mineral medicine, has been widely researched in the past century for their biological and pharmacological activities. However, their mechanism and clinical efficacy studies did not always give expected results. For example, the most commonly used Chinese herb for menstrual disorders, Radix Angelicae sinensis, showed neither estrogenic nor progesteronic activity in laboratory and clinical studies. Its efficacy should not be denied simply based on such results, because it is mostly used together with other herbs in formulae. Moreover, its regulation on menstruation may take effect through other mechanisms, such as regulation of blood circulation. The key difference of Chinese medicine (CM) from conventional medicine is its unique holistic view on human body and diseases. CMM is mostly applied in clinic in the form of formulae. Study on individual CMM, simply using methods for development of conventional drugs, is unable to thoroughly reveal the power of CMM formulae. The reason may partly result from improper design due to the lack understanding about application principle of CMMs in CM, and/or to current lack of knowledge about the causes of some symptoms and diseases. This paper will introduce the importance of qi and blood in CM etiology and pathology, Zheng differentiation, formulation of CMMs, and explain why one formula can treat different diseases and one disease can be treated with different formulae. Examples in the paper will demonstrate that proper studies on Zheng and its corresponding clinically proven formulae could help scientists find new direction to explain and treat symptoms and diseases that so far modern medicine has been unable to, provided that the designer properly understands CM theories, etiology and pathology of CM, as well as modern medicine. Strategy suggestions about research methods for CMM and its formulae will be given at the end.

    Full Text Available A change from group housing to isolation in unfamiliar metabolic cages represents, for rodents, a significant emotional stress. We studied the effect of candesartan, a peripheral and central angiotensin II AT1-receptor antagonist, on the hormonal and sympathetic response to acute isolation. We pretreated rats with 1 mg/kg/day candesartan for 13 days via subcutaneously implanted osmotic minipumps, followed by 24-hour isolation in individual metabolic cages. We measured brain, pituitary and adrenal angiotensin II (Ang II receptor binding by quantitative autoradiography and adrenal hormones and catecholamines by RIA and HPLC. Isolation increased adrenal catecholamines, aldosterone and corticosterone, AT1-receptor binding in the zona glomerulosa and AT2-receptor binding in the adrenal medulla. Candesartan pretreatment decreased adrenal catecholamines, aldosterone and corticosterone, AT1-receptor binding in adrenal zona glomerulosa and medulla, pituitary gland and the hypothalamic paraventricular nucleus, and AT2-receptor binding in adrenal medulla, but increased AT2-receptor binding in zona glomerulosa. We conclude that peripheral and central AT1-receptor blockade with candesartan decreases the sympatho-adrenal and hormonal response to acute stress. Our results indicate that Ang II is an important stress hormone and suggest that blockade of the physiologically active AT 1-receptors could influence stress-related disorders.

    The protein tyrosine phosphatases(PTPs) comprise a family of enzymes that specifically dephosphorylate tyrosyl residues.Among them,SHP-1 has been regarded as one of the best validated intracellular tyrosine phosphatases.Downregulation of SHP-1 has shown remarkable efficacy in improving insulin sensitivity in vivo in insulin signaling pathway.In this study,we found the role of Candesartan cilexetil targeting at SHP-1.The results indicate that Candesartan cilexetil was a competitive inhibitor to SHP-1(IC50=85.6 μmol/L and Ki=24 μmol/L).We also found that Candesartan cilexetil was more sensitive towards SHP-1 compared with other PTPs.Through the consequence of Western blotting,it showed that Candesartan cilexetil can strengthen the level of tyrosine phosphorylation of several key cellular proteins[such as insulin receptor(IR),insulin receptor substrate(IRS) and ERK] in insulin signaling pathway in HepG2 cells and improve the insulin sensitivity through inhibiting the protein phosphorylation of SHP-1.These findings showed that Candesartan cilexetil might be an important inhibitor of SHP-1 and had a great application potential in the treatment of diabetes through inhibiting the level of SHP-1 in insulin signaling pathway.

    Full Text Available Thomas Mengden1, Sakir Uen1, Peter Bramlage21Centre of Vascular Medicine, Herz- und Gefäß-Campus, Bad Nauheim, Germany; 2Institute for Cardiovascular Pharmacology and Epidemiology, Mahlow, GermanyAbstract: Hypertension treatment and control is largely unsatisfactory when guideline-defined blood pressure goal achievement and maintenance are considered. Patient- and physician-related factors leading to non-adherence interfere in this respect with the efficacy, tolerability, and convenient use of pharmacological treatment options. Blockers of the renin–angiotensin system (RAS are an important component of antihypertensive combination therapy. Thiazide-type diuretics are usually added to increase the blood pressure lowering efficacy. Fixed drug–drug combinations of both principles like candesartan/hydrochlorothiazide (HCTZ are highly effective in lowering blood pressure while providing improved compliance, a good tolerability, and largely neutral metabolic profile. Comparative studies with losartan/HCTZ have consistently shown a higher clinical efficacy with the candesartan/HCTZ combination. Data on the reduction of cardiovascular endpoints with fixed dose combinations of antihypertensive drugs are however scarce, as are the data for candesartan/HCTZ. But many trials have tested candesartan versus a non-RAS blocking comparator based on a standard therapy including thiazide diuretics. The indications tested were heart failure and stroke and particular emphasis was put on elderly patients or those with diabetes. In patients with heart failure, for example, the fixed dose combination might be applied in patients in whom individual titration resulted in a dose of 32 mg candesartan and 25 mg HCTZ which can then be combined into one tablet to increase compliance with treatment. Also in patients with stroke the fixed dose combination might be used in patients in whom maintenance therapy with both components is considered. Taken together candesartan

    The complex production processes and long industrial chain in traditional Chinese medicine (TCM) market result in difficulty in Chinese market microstructure research. Based on the defining the logical relationships among different concepts. This paper divides TCM market into two stages as Chinese materia medica resource market and traditional Chinese Patent Medicines market. Under this foundation, we investigated the supply capacity, approaching rules and motivation system of suppliers in TCM market, analyzed the demand situation in the perspective of demand side, and evaluated the purchasing power in terms of population profile, income, and insurance. Furthermore we also analyzed the price formation mechanism in two stages of TCM market. We hope this study can make a positive and promotion effect on TCM market related research.

    Full Text Available Gerd Bönner1, Bernhard Landers2, Peter Bramlage31Park-Klinikum Bad Krozingen, Germany; 2Internal Medicine Practice, Diabetes Center, Mayen, Germany; 3Institute for Cardiovascular Pharmacology and Epidemiology, Mahlow, GermanyBackground: Candesartan cilexetil has been shown to effectively reduce blood pressure and cardiovascular risk. Whether it is advantageous to combine candesartan cilexetil with low-dose hydrochlorothiazide (HCTZ or uptitrate it in cases of insufficient blood pressure control has not been fully investigated under routine clinical conditions.Methods: CHILI Triple T is a prospective, noninterventional, observational study. Patients with uncontrolled hypertension and added cardiovascular risk received a fixed-dose combination of candesartan cilexetil 16 mg and HCTZ 12.5 mg (combination therapy group or high-dose monotherapy with candesartan cilexetil 32 mg (high-dose monotherapy group.Results: A total of 4600 patients with a mean age of 63.1 ± 11.0 years, of which 44.7% were female, was included. The combination therapy group had 3337 patients, and the high-dose monotherapy group 1263 patients. Patients in both treatment groups were comparable with respect to age and gender, but patients receiving high-dose monotherapy had a slightly higher mean systolic blood pressure, more prior revascularizations, renal insufficiency, diabetic nephropathy, peripheral artery disease, and a lower ankle brachial index. The use of combination therapy resulted in a blood pressure reduction of -28.5 ± 13.8/-14.2 ± 9.4 mm Hg (P < 0.001 vs 160.2 ± 13.3/94.5 ± 8.2 mm Hg at baseline. The use of high-dose monotherapy reduced blood pressure by -29.73 ± 15.3/-14.1 ± 9.6 mm Hg (P < 0.001 vs 162.4 ± 14.7/94.7 ± 8.7 mm Hg at baseline.

    Stroke is the second leading cause of death in industrialized countries and the most frequent cause of permanent disability in adults worldwide. The final outcome of stroke is determined not only by the volume of the ischemic core, but also by the extent of secondary brain damage inflicted to penumbral tissues by brain swelling, impaired microcirculation, and inflammation. The only drug approved for the treatment ischemic stroke is recombinant tissue plasminogen activator (rt-PA). The current study was designed to investigate the protective effects of candesartan (0.15 mg/kg, orally) and glycyrrhizin (30 mg/kg, orally) experimentally-induced ischemic brain damage in C57BL/6 mice (middle cerebral artery occlusion, MCAO) in comparison to the effects of a standard neuroprotective drug (cerebrolysin, 7.5 mg/kg, IP). All drugs were administered 30 min before and 24h after MCAO. Both candesartan and glycyrrhizin ameliorated the deleterious effects of MCAO as indicated by the improvement in the performance of the animals in behaviour tests, reduction in brain infarction, neuronal degeneration, and leukocyte infiltration. In addition, MCAO induced a significant upregulation in the different elements of the TLR pathway including TLR-2 and TLR-4, Myd88, TRIF and IRF-3 and the downstream effectors TNF-α, IL-1β, IL-6 and NF-kB. All these changes were significantly ameliorated by treatment with candesartan and glycyrrhizin. The results of the current study represent a new indication for both candesartan and glycyrrhizin in the management of ischemic stroke with effects comparable to those of the standard neuroprotective drug cerebrolysin.

    Full Text Available The present study aimed to investigate the action of angiotensin II (AII on renal perfusion pressure and renal vascular resistance using noncompetitive AT1-receptor antagonist (candesartan or CV 11974. Experiments were performed in isolated kidney of adult male Wistar rats. Kreb's Henseleit solution was perfused into the renal artery at the rate of 3.5 ml/min. This flow rate was designed in order to maintain renal perfusion pressure between 80-120 mm Hg. Dose-response relationship between perfusion flow rate and AII concentration were studied. Renal perfusion pressure in response to 1, 10 and 100 nM AII were increased from basal perfusion pressure of 94±8 mm Hg to 127±6, 157±12 and 190±16 mm Hg, respectively. Administration of perfusate containing 11.4 μM candesartan for 30 min had no effect on the basal perfusion pressure. However, this significantly reduced renal perfusion pressure in the presence of AII (1, 10 and 100 nM by 39%, 47% and 61%, (n=7, P<0.05 respectively. At the basal perfusion pressure, calculated renal vascular resistance was 27±2 mm Hg · min · ml-1. However, the vascular resistance were found to be 41±1, 45±2 and 47±2 mm Hg · min · ml-1 when 1, 10 and 100 nM AII were added. Moreover, this dose of candesartan also showed a significant decrease in renal vascular resistance at the corresponding doses of AII by 38%, 48% and 43%, (n=7, P<0.05 respectively. The higher dose of candesartan (22.7 μM completely inhibited the action of 1, 10 and 100 nM AII on renal vasoconstriction. These results may indicate that the action of AII on renal vascular resistance is via AT1-receptor, at least in rat isolated perfusion kidney.

    A sensitive, specific and rapid liquid chromatography - tandem mass spectrometry method was developed and validated for the determination of candesartan in human plasma. Analyte was separated from endogenous components present in plasma by solid phase extraction. Chromatographic separation was performed on Gemini C18 analytical column using mobile phase acetonitrile - 5 mM ammonium formate pH 2 (90:10, v/v) at flow rate of 0.3 mL/min. For detection, tandem mass spectrometry in SRM mode with positive electrospray ionization was used. The mass transitions m/z 441.1 > 263.1 and 445.1 > 267.1 were used to determine candesartan by using candesartan-d4 as an internal standard. After development, the method was validated according to the requirements of EMA regulatory guidelines in the concentration range 1 - 400 ng/ml in human plasma. Limit of quantification (LLOQ) was 1 ng/ml. The developed and validated method proved to be very fast and reproducible and was therefore successfully implemented in pharmacokinetic and bioequivalence studies with large number of study samples.

A total of 53 consecutive hypertensive patients with MetS were randomly assigned to the candesartan group, in which candesartan was added on, or the CCBs group, in which CCBs were added on. Clinical and biological parameters were obtained before and after the 12-month treatment period. The primary measure of efficacy was the %change in CAVI. When treated with candesartan, but not CCBs, CAVI significantly decreased from 8.7 to 7.7 by 11%. Blood pressure (BP significantly decreased with both treatments, but the differences between groups were not significant. The changes in other parameters remained unchanged in both the groups. Analysis of covariance found that both the BP reduction and the therapy difference contributed to the decrease in CAVI, but the BP reduction was not involved in the decrease in CAVI caused by the difference in the therapy. Candesartan may be a better antihypertensive drug than CCBs to that subclinical atherosclerosis of patients with MetS.Keywords: albuminuria, ambulatory blood pressure, calcium channel blockers, carotid ­intima-media thickness

    Full Text Available The solubility, absorption and distribution of a drug are involved in the basic aspects of oral bioavailability Solubility is an essential characteristic and influences the efficiency of the drug. Over the last ten years, the number of poorly soluble drugs has steadily increased. One of the progressive ways for increasing oral bioavaibility is the technique of nanoparticle preparation, which allows many drugs to thus reach the intended site of action. Candesartan cilexetil and atorvastatin, belonging to class II of the biopharmaceutical classification system, were chosen as model active pharmaceutical ingredients in this study. Forty samples were prepared either by antisolvent precipitation/solvent evaporation method or by the emulsion/solvent evaporation technique with various commonly used surface-active excipients as nanoparticle stabilizers. All samples were analyzed by means of dynamic light scattering. The particle size of the determined 36 nanoparticle samples was to 574 nm, whereas 32 samples contained nanoparticles of less than 200 nm. Relationships between solvents and excipients used and their amount are discussed. Based on the results the investigated solvent evaporation methods can be used as an effective and an affordable technique for the preparation of nanoparticles.

    Full Text Available Available tablets or capsules for adults are often used to prepare extemporaneously formulated medicines appropriate for children. The most acceptable drug forms in pediatric population are oral liquids and pharmacists use commercial dispersing media to compound syrups from an active substance or from tablets available on the market. In many countries ready-to-use dispersing media are not available or refunded, but pharmacists can use other compounded media, providing their compatibility and stability are proven. The aim of this study was to formulate and evaluate the stability of syrups with candesartan cilexetil (1 mg mL-1 and valsartan (4 mg mL-1 extemporaneously prepared using commercial tablets (Diovan® and Atacand®. The following three different suspending media, which could be easily made in a pharmacy, were investigated: V1 - with xanthan gum (0.5 %, V2 - the USP/NF vehicle for oral solution and V3 - the medium based on a simple sucrose syrup. The stability of preparations was studied during 35 days of storage in a dark place at controlled temperature of 25 and 4 °C. During the study, microscopic observation was carried out and pH, viscosity, and concentration of candesartan cilexetil and valsartan were analyzed. Syrups with valsartan prepared with V2 and V3 media were stable for 3 or 4 weeks when stored at 25 °C, while syrups with candesartan were stable for as long as 35 days. For syrups prepared using V1 medium, the 14-day expiry date was not achieved because of microbial deterioration.

    Introduction The increase of potential side effects and safety concerns of conventional medicaments have led to the recent popularity of herbal alternative medications. The herbal products are known for its high antimicrobial activity, biocompatibility, anti-inflammatory and antioxidant properties. Aim The purpose of this study was to investigate and compare the effectiveness of Propolis, Metronidazole with Chlorhexidine gel, Curcuma Longa and Calcium Hydroxide for elimination of E.faecalis bacteria in extracted teeth samples. Materials and Methods Ninety extracted single rooted intact teeth were taken for the study. Decoronation, removal of apices and chemomechanical preparation was done for all samples. These sterilized samples were then contaminated with pure culture of E.faecalis under laminar flow. The samples were incubated for a period of 21 days. The infected samples were assigned to 5 groups: Group I- Propolis; Group II- Metronidazole with Chlorhexidine gel; Group III- Calcium hydroxide; Group IV- Curcuma Longa; and control group- Saline. Efficacy of newer intracanal medicaments against E.faecalis were carried out in the samples at the end of 1, 2 & 5 days for each group with the help of colorimeter. Student paired t-test, ANOVA and multiple tukey test were used for statistical analysis. Results The value of optical density was statistically significant in all groups when compared to that of control group. Group I (Propolis) produced better antimicrobial efficacy followed by Chlorhexidine Metronidazole combination, Curcuma Longa and Calcium hydroxide. Conclusion Within the limitations of this study, it can be concluded that Propolis showed better antimicrobial properties against E.faecalis than other medicaments. PMID:26673857

  11. In vitro studies on interactions of iron salts and complexes with food-stuffs and medicaments.

    It has been shown in the present study that food components such as phytic acid, oxalic acid, tannin, sodium alginate, choline and choline salts, vitamins A, D3 and E, soy oil and soy flour, do not undergo any interactions with iron(III)-hydroxide polymaltose complex (Ferrum Hausmann). Phytic acid, oxalic acid, tannin and sodium alginate, however, react with iron(II) or iron(III)-salts at pH values of 3.0, 5.5 and 8.0, giving rise to iron complexes. Trimethylamine-N-oxide, which is present in fish meal, reacts with iron(II)-sulphate to produce iron(III) reaction products; it does not react with iron(III)-hydroxide polymaltose complex. Special soybean flours show no irreversible adsorption or precipitation with iron(III)-hydroxyide polymaltose complex over the pH range 3.0-8.0, in contrast to iron(II)-sulphate. Antacids containing aluminium hydroxide, talc, ion exchange resins or other unabsorbable, insoluble components absorb iron(III)-hydroxide polymaltose complex in the pH range 3.0-8.0 in a reversible manner, while the strong adsorption or precipitation observed with iron(II)-sulphate at pH 8.0 is irreversible. No interaction was observed between the steroid hormones studied and iron(II)-sulphate or iron(III)-hydroxide polymaltose complex. On the basis of the measured compatibilities, iron(III)-hydroxide polymaltose complex can be administered orally simultaneously with many other drugs, without prejudicing the absorption of iron or of the other drug as is often seen with iron(II) and iron(III) salts.

    In this paper, I investigated the influence of Compendium of Materia Medica (CM) on Records for Rural Life of Chosun Gentlemen (RRC), and refuted Miki Sakae's opinion, CM did not have much impact on the Materia Medica in the late period of the Chosun Dynasty. When Li Shizhen published CM, it resulted in a shift of mainstream of Materia Medica in Eastern Asia from Classified Emergency Materia Medica to CM and a new categorizing system of Materia Medica by CM led to the division of Materia Medica into medicine and natural history. It is obvious that doctors of the Chosun Dynasty also adopted the latest achievements of Materia Medica by CM, but so far there have been few studies to clarify this. Seo yugu was a scholar of the Realist School of Confucianism during the late period of the Chosun Dynasty, and RRC is his representative work. RRC is a massive encyclopedia of natural history that covers vast areas of science from agriculture, floriculture, writing and drawing, architecture, diet, and medicine, among others which absorbed the achievements of CM, the best Materia Medica book at that time. Miki Sakae also highly regarded the encyclopedic knowledge of RRC, but devalued the results of Materia Medica. He only described a part of RRC's Materia Medica, nurturing volume, on the view of life nurturing and mentioned that it had been strongly influenced by China. According to this study, a large portion of RRC, especially regarding Materia Medica, depends on CM. Seo yugu had accepted the categorizing system and new medicinal information of CM, at the same time he modified the categorizing system of CM practically by the subject of each volume of RRC. We can find many quotations of CM except the nurturing volume, but other books, Treasured Mirror of Eastern Medicine, Materia Medica for Relief of Famines are also quoted. Furthermore, Seo yugu emphasized the differences of natural environments between Chosun and China, and specified the editing criteria, "to be useful in

    Inflammatory markers, their relation to maintenance of sinus rhythm after electrical cardioversion for atrial fibrillation (AF), and the effect of candesartan were investigated in a double-blind placebo-controlled study (CAPRAF). One hundred seventy-one patients with persistent AF were randomly assigned to receive candesartan 8 mg/day or placebo for 3 to 6 weeks before and candesartan 16 mg/day or placebo for 6 months after electrical cardioversion. Serum levels of high-sensitivity C-reactive protein (hs-CRP), tumor necrosis factor-alpha, interleukin-6, P-selectin, E-selectin, CD-40 ligand, and vascular cell adhesion molecule-1 were measured at baseline and end of study. Compared with patients with a relapse of AF, patients still in sinus rhythm at 6 months after cardioversion (n = 40) had lower baseline hs-CRP and E-selectin levels: median 2.36 mg/L (25th, 75th percentiles 1.28, 4.09) versus 3.44 mg/L (25th, 75th percentiles 1.66, 6.05, p = 0.031) and 32 ng/ml (25th, 75th percentiles 23, 42) versus 37 ng/ml (25th, 75th percentiles 28, 51, p = 0.042), respectively. Neither sustained sinus rhythm for 6 months nor treatment with candesartan had an impact on measured concentrations of markers of inflammation. In conclusion, low hs-CRP and E-selectin at baseline were associated with maintenance of sinus rhythm after electrical cardioversion.

    There were 268 kinds of medicines recorded in the book of Lei Gong's Treatise on preparation and broiling of materia medica (Leigong Paozhi Lun). Among these medicines, 178 medicines were prepared with adjuvant medicines, including general and special compatible adjuvant medicines. These adjuvant medicines used in this book can be explained by the theory of "seven-relation compatibility". The author tried to explain the usage and their compatibility of these adjuvant medicines and put forward that attention should be paid to the changes in functions of medicines and the influences of society should be paid attention.

    The aim of this study is to develop novel proniosomal tablets of candesartan cilexetil. Drug loaded proniosomes were prepared as dry powder by slurry method. The critical parameters of the production process were the type of the carrier (sorbitol, maltodextrin, and lactose), addition of charge inducers, rotation speed of the rotavapor and solvent evaporation temperature. The effects of these parameters on proniosome specifications such as the recovery, drug loading, drug release were investigated and also the influence on the particle size and surface charge of the niosomes derived by the hydration of proniosomes were evaluated. The mean particle size and drug loading of niosomes formed from the hydrated proniosomes were 204 ± 2 nm and 99.09 ± 0.04% respectively, with a negative charge -43.65 ± 0.54 mV. The proniosomes demonstrated good flowability, compressibility and consolidation properties both alone and together with the tableting agents (microcrystalline cellulose and cross-linked poly vinylpyrrolidone). The niosomes derived by the hydration of proniosomal tablets preserved their initial properties. Compatibly with the increased in vitro drug dissolution rate, the relative bioavailability of drug from proniosomal tablets increased 1.86-fold and 2.75-fold and higher candesartan plasma levels were achieved within shorter time compared to the pure drug.

    Full Text Available Abstract Background Studies focusing on the add-on effects of angiotensin II type 1 receptor blockers (ARBs other than their antihypertensive effect are receiving attention. However, the effects of prolonged administration of ARBs on lipid metabolism in clinical cases are unclear. Our aims were to survey the changes in plasma lipid profile in patients with hypertension over a one-year period, and to examine the correlations between these values and the time after the start of ARB monotherapy with candesartan. Methods We carried out candesartan monotherapy in patients with mild to moderate hypertension and examined the longitudinal changes in plasma lipid profile. Data from 405 patients for triglyceride (TG, 440 for total cholesterol (TC, 313 for high density lipoprotein cholesterol (HDL-C and 304 for low density lipoprotein cholesterol (LDL-C were obtained from the electronic medical records (EMRs in the Clinical Data Warehouse (CDW of Nihon University School of Medicine (NUSM. The inverse probability of treatment weighting (IPTW method (calculated from the inverse of the propensity score was used to balance the covariates and reduce bias in each treatment duration. Linear mixed effects models were used to analyse the relationship between these longitudinal data of blood examinations and covariates of patient sex, age, diagnosis of diabetes mellitus (DM and duration of candesartan monotherapy. Results Plasma HDL-C level was associated with sex, duration of treatment, and interaction of sex and treatment duration, but not with age or diagnosis of DM. HDL-C level was significantly decreased during the 6~9 months period (p = 0.0218 compared with baseline. TG and TC levels were associated with sex, but not with age, diagnosis of DM or treatment duration. LDL-C level was not associated with any covariate. Analysis of the subjects divided by sex revealed a decrease in HDL-C in female subjects (during the 6~9 months period: p = 0.0054, but not in male

    During the period of the Republic of China, researches of experiments on Chinese materia medica developed extensively with the scientific process of Chinese medicine. Although the technology standard was relatively low and the reference value, limited. The experiences, positive or negative, obtained at that time still has reference significance to today's Chinese medicine scientific research. The notion that traditional Chinese medical and scientific research be conducted under the guidance of TCM theory; valuable experience contained in the ancient literature of traditional Chinese medicine be collected; and the transformation capacity of scientific research be elevated, has been accepted by modern TCM professionals. If you go back to the history, it can be seen that this notion was summarized through repeated practice during the critical moment of traditional Chinese medicine, which should be emphasized and its understanding deepened at any time.

    This study will determine the ways in which the ancient learning (gu xue, ) scholarship of the Seongho School, and its interest in the materia medica (ben cao xue, ) were related during the late Joseon period. The Seongho School centered its studies mainly on classical Chinese texts of the Han (206 BC-AD 220) and pre-Han (?-221 BC) (xian-qin lianghan, ) periods rather than those of the Tang and Song dynasties (618-1279). gu xue scholarship emerged during the Ming dynasty era (1368 -1644) as an alternative to the scholarly trends of the Song dynasty, which were dependent on Zhu Xi's (, 1130-1200) Neo-Confucianism and its interpretation of Han and pre-Han classical Chinese texts. This scholarly trend influenced Korean and Japanese literature, philosophy, and even medicine from the seventeenth through the nineteenth centuries. Focusing on Korean scholarship, we find a great deal of research regarding the influence of gu xue on Korean classical Chinese literature and Confucian philosophy in the late Joseon period; however, no study has examined how this style of scholarship influenced the field of medicine during the same period. This study will investigate how the intellectuals of the Seongho School, who did the most to develop gu xue among Joseon intellectuals, were influenced by this style of scholarship in their study of the materia medica. Jeong Yak-yong (1762-1836), the representative intellectual of the Seongho School, did not focus on complicated metaphysical medical theories, such as the Yin-Yang and Five Elements theory (yin yang wu xing shui, ) or the Five Movements and Six Atmospheres theory (wu yun liu qi shui, ). Instead, his interests lay in the exact diagnoses of diseases and meticulous herbal prescriptions which formed an essential part of the Treatise on Exogenous Febrile Disease (Shang han lun, ) written by Zhang Zhungjing (, 150-219) in the Han dynasty. The Treatise was compatible with the scholarly purpose of gu xue in that they both

    Based on the ecological and economic problems in Good Agriculture Practice (GAP) of Chinese material medica, we introduced the origin, concept, features and operative technology of eco-agriculture worldwide, emphasizing its modes on different biological levels of landscape, ecosystem, community, population, individual and gene in China. And on this basis, we analyzed the background and current situation of eco-agriculture of Chinese materia medica, and proposed its development ideas and key tasks, including: (1) Analysis and planning of the production pattern of Chinese material medica national wide. (2) Typical features extraction of regional agriculture of Chinese materia medica. (3) Investigation of the interaction and its mechanism between typical Chinese materia medica in each region and the micro-ecology of rhizosphere soil. (4) Study on technology of eco-agriculture of Chinese materia medica. (5) Extraction and solidification of eco-agriculture modes of Chinese materia medica. (6) Study on the theory of eco-agriculture of Chinese materia medica. Also we pointed out that GAP and eco-agriculture of Chinese material medica are both different and relative, but they are not contradictory with their own features. It is an irresistible trend to promote eco-agriculture in the GAP of Chinese material medica and coordinate ecological and economic development.

    Medicaments are reported as the most common cause of urticaria. The objective of this study was to determine, by retrospective analysis of 132 pediatric patients treated at the Pulmonology and Allergology ward of the Department of Pediatrics, Banja Luka, over a 5-year period, the scope to which medicaments act as the possible cause of urticaria. Results of the study showed that the disease manifested mostly in male children (59.8), mainly of pre-school and school age rather than <1 year age group. Acute urticaria predominated, and it was recorded in 91.7% of cases. A medicament as the possible etiologic factor of acute urticaria was found in 29.8% of cases. Regarding chronic urticaria, in most cases the cause of disease remained unknown (63.6%), whereas a medicament and infection as the possible causal factors were found in 9.1% of cases. Before the occurrence of urticaria, 37 (28%) children took some medicament. Usually, these were antibiotics (45.9%), antipyretics (35.1%), or a combination of antibiotics and antipyretics (16.2%). Penicillin V, G or ampicillin were the most frequently used antibiotics (88.2%), whereas acetylsalicylic acid was the most frequently used antipyretic (53.8%). In 28% of the children suffering from acute urticaria, apart from taking some medicament, clinically manifested infection was also recorded, mostly of the respiratory system, so it could not be stated for sure whether the medicament or infection was the etiologic factor for the occurrence of disease. In only two cases it could be stated for sure that a medicament was the cause of urticaria, one acute and chronic urticaria each

    DNA barcoding is a novel molecular identification method that aids in identifying traditional Chinese materia medica using traditional identification techniques. However, further study is needed to assess the stability and accuracy of DNA barcoding. Flos Lonicerae Japonicae, a typical medicinal flower, is widely used in China, Korea, and other Southeast Asian countries. However, Flos Lonicerae Japonicae and its closely related species have been misused and traded at varying for a wide range of prices. Therefore, Flos Lonicerae Japonicae must be accurately identified. In this study, the ITS2 and psbA-trnH regions were amplified by polymerase chain reaction (PCR). Sequence assembly was performed using CodonCode Aligner V 3.5.4. The intra- versus inter-specific variations were assessed using six metrics and "barcoding gaps." Species identification was conducted using BLAST1 and neighbor-joining (NJ) trees. Results reveal that ITS2 and psbA-trnH exhibited an average intraspecific divergence of 0.001 and 0, respectively, as well as an average inter-specific divergence of 0.0331 and 0.0161. The identification efficiency of ITS2 and psbA-trnH evaluated using BLAST1 was 100%. Flos Lonicerae Japonicae was formed into one clade through the NJ trees. Therefore, Flos Lonicerae Japonicae can be stably and accurately identified through the ITS2 and psbA-trnH regions, respectively.

    Full Text Available The symbiotic association between Medicago truncatula and Sinorhizobium meliloti is a well-established model system in the legume-Rhizobium community. Despite its wide use, the symbiotic efficiency of this model has been recently questioned and an alternative microsymbiont, S. medicae, has been proposed. However, little is known about the physiological mechanisms behind the higher symbiotic efficiency of S. medicae WSM419. In the present study, we inoculated M. truncatula Jemalong A17 with either S. medicae WSM419 or S. meliloti 2011 and compared plant growth, photosynthesis, N2-fixation rates, and plant nodule carbon and nitrogen metabolic activities in the two systems. M. truncatula plants in symbiosis with S. medicae showed increased biomass and photosynthesis rates per plant. Plants grown in symbiosis with S. medicae WSM419 also showed higher N2-fixation rates, which were correlated with a larger nodule biomass, while nodule number was similar in both systems. In terms of plant nodule metabolism, M. truncatula-S. medicae WSM419 nodules showed increased sucrose-catabolic activity, mostly associated with sucrose synthase, accompanied by a reduced starch content, whereas nitrogen-assimilation activities were comparable to those measured in nodules infected with S. meliloti 2011. Taken together, these results suggest that S. medicae WSM419 is able to enhance plant carbon catabolism in M. truncatula nodules, which allows for the maintaining of high symbiotic N2-fixation rates, better growth and improved general plant performance.

    Recently, there has been a growing interest in studying the role of angiotensin II type-2 (AT(2)) receptor in renal/cardiovascular function in pathological conditions. The present study was designed to determine the functional role of the AT(2) receptors on natriuresis/diuresis and compare the level of the tubular AT(2) receptor expression in obese and lean Zucker rats (12 weeks old). Under anesthesia, candesartan (angiotensin II type 1 [AT(1)]-specific antagonist; 100 microg/kg bolus) produced natriuresis/diuresis to a greater degree in obese than in lean rats. The specific AT(2) antagonist PD123319 (50 microg/kg per minute) after candesartan administration abolished the natriuretic/diuretic effects of candesartan in obese rats but not in lean rats. Infusion of AT(2) receptor agonist, CGP-42112A (1 microg/kg per minute), produced greater increase in sodium and urine excretion over basal in obese than in lean rats. The presence of the AT(2) receptor expression in the brush-border and basolateral membranes was confirmed by Western blotting using specific antibody and antigen-blocking peptide. Densitometric analysis of the bands revealed approximately 1.5- to 2.0-fold increase in the AT(2) receptor proteins in both membranes of obese compared with lean rats. Our results suggest upregulation of the AT(2) receptors, which play a role in mediating the natriuretic/diuretic effects of AT(1) receptor blockers in obese Zucker rats. We speculate that AT(2) receptors, by promoting sodium excretion, may protect obese Zucker rats against blood pressure increase associated with sodium and water retention.

    Candesartan cilexetil (CC) is used in the treatment of hypertension and heart failure. It has poor aqueous solubility and low oral bioavailability. In this work, CC loaded solid lipid nanoparticles (CC-SLNs) were developed to improve the oral bioavailability. Components of the SLNs include either of trimyristin/tripalmitin/tristearin, and surfactants (Poloxamer 188 and egg lecithin E80). The CC loaded nanoparticles were prepared by hot homogenization followed by ultrasonication method. The physicochemical properties, morphology of CC-SLNs were characterized, the pharmacokinetic and pharmacodynamic behaviour of CC-SLNs were evaluated in rats. Stable CC-SLNs having a mean particle size of 180-220 nm with entrapment efficiency varying in between 91-96% were developed. The physical stability of optimized formulation was studied at refrigerated and room temperature for 3 months. Further, freeze drying was tried for improving the physical stability. DSC and XRD analyses indicated that the drug incorporated into SLN was in amorphous form but not in crystalline state. The SLN-morphology was found to be nearly spherical by electron microscopic studies. Pharmacokinetic results indicated that the oral bioavailability of CC was improved over 2.75-fold after incorporation into SLNs. Pharmacodynamic study of SLNs in hypertensive rats showed a decrease in systolic blood pressure for 48 h, while suspension showed a decrease in systolic blood pressure for only 2 h. Taken together, these effects are due to enhanced bioavailability coupled with sustained action of CC in SLN formulation. Thus, the results conclusively demonstrated the role of CC-SLNs for a significant enhancement in oral bioavailability along with improved pharmacodynamic effect.

    Full Text Available Aims. This study examined the extent to which intervisit corticosteroid-based antibiotic pastes (CAP medicaments contribute to staining of tooth structure after attempted removal by irrigation techniques. Methods. A total of 140 roots were prepared and the canals were filled with Ledermix paste (demeclocycline, Odontopaste (clindamycin, and Doxypaste (doxycycline. The pastes were removed after 2 or 4 weeks of storage in the dark using EDTA and NaOCl with either a 27-gauge-slotted needle or an EndoActivator (Dentsply. The roots were then exposed to an intense light source for 30 minutes each week and photographed after a further 1, 3, or 6 months. Digital images were standardized and data for changes in luminosity were analysed using repeated measures ANOVA and a post hoc test. Results. Removal of the medicament did not prevent later discolouration. There was no significant difference between the paste removal methods. Ledermix paste caused the greatest darkening compared to the untreated controls, for both application periods and both methods of removal. Doxypaste and Odontopaste caused less darkening than Ledermix. Conclusion. Medicaments that stain teeth may continue to discolour teeth despite best attempts to remove them. This study stresses the importance of material selection and minimising contact of Ledermix within the coronal aspects of teeth.

    Modern, biologic root canal therapy should be performed with suitable irrigating solutions and intracanal medicaments. The goal of endodontic treatment is to free the treated tooth from infection and prevent reinfection as thoroughly as possible by means which do not put the organism at risk. In this review of the literature, an evidence-based concept for irrigation and medication of root canal systems is presented. Irrigants and medicaments are discussed with respect to their antimicrobial, tissue-dissolving and endotoxin-decontaminating capacity in relation to their systemic toxicity. Recent findings pertaining to interactions of root canal medicaments and irrigating solutions and their impact on a sound irrigating and medicating concept are discussed.

    Trials with pulverized brand-name antihypertensive drugs suggest that, from the perspective of taste acceptability, crushed candesartan, chlortalidon, hydrochlorothiazide, lercanidipine and lisinopril should be preferred to pulverized amlodipine, atenolol, bisoprolol, enalapril, irbesartan, losartan, ramipril, telmisartan and valsartan. Brand-name antihypertensive drugs and the corresponding generic medicines have never been compared with respect to their taste acceptability. We therefore investigated among healthy health care workers the taste acceptability of a pulverized 1 mg-test dose of the brand-name and two generics containing either the dihydropyridine calcium-channel blocker amlodipine (Norvasc(®), Amlodipin-Mepha(®) and Amlodipin Pfizer(®)) or the angiotensin receptor antagonist candesartan (Atacand(®), Cansartan-Mepha(®) and Pemzek(®)). For this purpose, a smiley-face scale depicting four degrees of pleasure was used. Between November and December 2013, the taste test was performed among 19 nurses (15 female and 4 male subjects) and 12 physicians (5 female and 7 male subjects) aged between 25 and 49 years. Pulverized brand-names and generics containing either amlodipine or candesartan did not differ with respect to their taste acceptability.

    Standards of commodity classes of Chinese materia medica is an important way to solve the "Lemons Problem" of traditional Chinese medicine market. Standards of commodity classes are also helpful to rebuild market mechanisms for "high price for good quality". The previous edition of commodity classes standards of Chinese materia medica was made 30 years ago. It is no longer adapted to the market demand. This article researched progress on standards of commodity classes of Chinese materia medica. It considered that biological activity is a better choice than chemical constituents for standards of commodity classes of Chinese materia medica. It is also considered that the key point to set standards of commodity classes is finding the influencing factors between "good quality" and "bad quality". The article also discussed the range of commodity classes of Chinese materia medica, and how to coordinate standards of pharmacopoeia and commodity classes. According to different demands, diversiform standards can be used in commodity classes of Chinese materia medica, but efficacy is considered the most important index of commodity standard. Decoction pieces can be included in standards of commodity classes of Chinese materia medica. The authors also formulated the standards of commodity classes of Notoginseng Radix as an example, and hope this study can make a positive and promotion effect on traditional Chinese medicine market related research.

    Chinese Materia Medica (CMM) decoction dregs are the residues of medicinal materials after decoction. Accurate identification of CMM in decoction dregs will be helpful for exploring the causes of poisoning or other medical incidents arising after the ingestion of CMM decoctions. To determine how decoction affects the characteristics used to authenticate specific CMM, a systematic study was carried out. In this study, two pairs of Materia Medica that are commonly confused-namely, Baizhu (Atractylodis Macrocephalae Rhizoma) and Cangzhu (Atractylodis Rhizoma), Baishao (Paeoniae Alba Radix) and Chishao (Paeoniae Rubra Radix)-were chosen for investigation. Each pair of Materia Medica has similar morphology in appearance, but they have different functions in Chinese clinic. After decoction, with regard to gross morphological characters, the results showed that bark and wood could be easily distinguished. The striation of vessels and fibers became more prominent because of the contraction of parenchymatous cells, but the lignified cells did not. As for the microscopic characteristics, the cells with thickened walls, such as stone cells and fibers, were basically stable. Most of the parenchymatous cells were broken. Crystals of calcium oxalate showed no changes as they were insoluble in water. Starch granules were gelatinized and aggregated in parenchymatous cells. Inulins were substantially reduced in number as they dissolved in water during decoction. According to these changes in morphological and microscopic characteristics after decoction, the dregs of two pairs of Materia Medica could be distinguished.

    Since the research of molecular identification of Chinese Materia Medica (CMM) using DNA barcode is rapidly developing and popularizing, the principle of this method is approved to be listed in the Supplement of the Pharmacopoeia of the People's Republic of China. Based on the study on comprehensive samples, the DNA barcoding systems have been established to identify CMM, i.e. ITS2 as a core barcode and psbA-trnH as a complementary locus for identification of planta medica, and COI as a core barcode and ITS2 as a complementary locus for identification of animal medica. This article introduced the principle of molecular identification of CMM using DNA barcoding and its drafting instructions. Furthermore, its application perspective was discussed.

    Citrus medica cv. 'liscia' and C. medica cv. 'rugosa' are two taxa of citron, belonging to the biodiversity of South Italy, in particular of Amalfi Coast, in the Campania region. The chemical composition of the essential oils (EOs) from fruit peels of both C. medica cultivars was studied by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) analyses. In all, 100 compounds were identified, 82 for C. medica cv. 'liscia', accounting for 91.4% of the total oil, and 88 for C. medica cv. 'rugosa', accounting for 92.0% of the total oil. Monoterpene hydrocarbons are the main constituents in both oils of C. medica cv. 'liscia' (79.1%) and C. medica cv. 'rugosa' (80.2%). In both oils, limonene (67.2%-62.8%) and camphene (8.5%-10.9%) are the main constituents. The antimicrobial activity of the EOs was assayed against some bacterial strains: Bacillus cereus (DSM 4313), Bacillus cereus (DSM 4384), Staphylococcus aureus (DSM 25693), Pseudomonas aeruginosa (ATCC 50071), and Escherichia coli (DSM 8579). Low concentrations of C. medica cv. 'rugosa' EO showed an inhibitory effect on P. aeruginosa and higher concentrations inhibited more B. cereus (4384) and E. coli than S. aureus. The cytotoxicity of the EO was evaluated against SH-SY5Y cell line. The influence of the EO on the expression of adenylate cyclase 1 (ADCY1) was also studied. The antimicrobial activity registered confirm their traditional uses as food preserving agents and led us to hypothesize the possible use of these oils as antimicrobials. The alterations in ADCY1 expression suggested a role for limonene in effects on the central nervous system.

    2016-01-01

    Aims The aim of this study was to determine the relative antimicrobial effectiveness of these endodontic medicaments and various vehicles using an agar well diffusion assay. Materials and methods Double Antibiotic Paste(DAP), modified DAP, 2% Chlorhexidine gluconate and their combination with four vehicles namely Polyethylene glycol 400 (PEG), Propylene glycol (PG), combinations of PG with PEG and lastly Glycerine were tested using agar well diffusion assay. The minimum bactericidal concentration was noted against four standard strains of organisms ie Streptococcus mutans ATCC( American Type Culture Collection) 25175, Staphylococcus aureus ATCC 12598, Enterococcus faecalis ATCC 35550 and Eschericia coli ATCC 25922. Successful endodontic therapy depends upon thorough disinfection of root canals. In some refractory cases, routine endodontic therapy is not sufficient, so intracanal medicaments are used for proper disinfection of canals. Issues of resistance, limited spectrum of activity and lack of antifungal properties, the hunt for the ideal intracanal medicament continues. In this regard, the vehicles used to form the pastes play a supportive role by forming the appropriate consistency for placement and may dramatically influence their chemical characteristics like their solubility and diffusion. Thus, inorder to use safer and equally effective intracanal medicaments, Chlorhexidine gluconate is being unveiled in this study. Results The difference between the four vehicles when combined with the same endodontic medicament studied above is nonsignificant (NS) except against Porphyromonas gingivalis. Propylene glycol is significantly effective than Glycerine when used with DAP ie C+M medicament combination. (p = 0.029) Conclusion 2% chlorhexidine gluconate and modified DAP can definitely replace DAP and triple antibiotic paste as end-odontic medicaments with chlorhexidine having an added advantage of bactericidal action, substantivity, biocompatibility, low toxicity

    Full Text Available BACKGROUND: Cardiovascular disease (CVD is highly prevalent in patients with chronic kidney disease (CKD. Inhibition of the renin-angiotensinsystem (RAS in hypertension causes differential effects on central and brachial blood pressure (BP, which has been translated into improved outcome. The objective was to examine if a more complete inhibition of RAS by combining an angiotensin converting enzyme inhibitor (ACEI and an angiotensin receptor antagonist (ARB compared to monotherapy has an additive effect on central BP and pulse-wave velocity (PWV, which are known markers of CVD. METHODS: Sixty-seven CKD patients (mean GFR 30, range 13-59 ml/min/1.73 m(2 participated in an open randomized study of 16 weeks of monotherapy with either enalapril or candesartan followed by 8 weeks of dual blockade aiming at a total dose of 16 mg candesartan and 20 mg enalapril o.d. Pulse-wave measurements were performed at week 0, 8, 16 and 24 by the SphygmoCor device. RESULTS: Significant additive BP independent reductions were found after dual blockade in aortic PWV (-0.3 m/s, P<0.05 and in augmentation index (-2%, P<0.01 compared to monotherapy. Furthermore pulse pressure amplification was improved (P<0.05 and central systolic BP reduced (-6 mmHg, P<0.01. CONCLUSIONS: Dual blockade of the RAS resulted in an additive BP independent reduction in pulse-wave reflection and arterial stiffness compared to monotherapy in CKD patients.

    To determine the contents of candesartan in mouse plasma, and blood vessel and kidney sliced sections and also better understand its pharmacokinetics, we applied matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOFMS) and MALDI-imaging mass spectrometry (IMS) with the selected reaction monitoring (SRM) mode using a labeled-internal standard. The results of fundamental examinations showed that the slope of the resulting curves of candesartan in the plasma from the equation was 0.91 and the y-intercept was 0.02. Both intra- and inter-day accuracies (n=10) and the precision of candesartan in the plasma by MALDI-TOFMS with the SRM mode were in the range of 3.4 to 17.3% and 93.2%, respectively. The detection limit of candesartan in spiked plasma was 0.2 nmol/L. IMS analysis enabled us to clarify distinct spacial time-distribution images in sliced mouse blood vessel and kidney sections although it still needed to improve a protocol of quantification. Typical pharmacokinetic patterns of candesartan were obtained in the plasma and sliced kidney sections, but those in the blood vessel sections gradually increased 24 h after administration. MALDI-TOFMS and IMS with the SRM mode are powerful tools to identify the spacial distribution and traceability of candesartan in sliced blood vessel and tissue sections as well as in the plasma.

    Biological activity of cannabinoids is caused by binding to two cannabinoid receptors CB1 and CB2. Psychoactive is not only tetrahydrocannabinol (THC) but also: cannabidiol, cannabigerol or cannabichromen. Formerly, the usefulness of hemp was assessed in the relation to temporary appeasement of the symptoms of some ailments as nausea or vomiting. Present discoveries indicates that cannabis-based drugs has shown ability to alleviate of autoimmunological disorders such as: Multiple sclerosis (MS), Rheumatoid arthritis (RA) or inflammatory bowel disease. Another studies indicates that cannabinoids play role in treatment of neurological disorders like Alzheimer disease or Amyotrophic lateral sclerosis (ALS) or even can reduce spreading of tumor cells. Cannabinoids stand out high safety profile considering acute toxicity, it is low possibility of deadly overdosing and side-effects are comprise in range of tolerated side-effects of other medications. In some countries marinol and nabilone are used as anti vomiting and nausea drug. First cannabis-based drug containg naturally occurring cannabinoids is Sativex. Sativex is delivered in an mucosal spray for patients suffering from spasticity in MS, pain relevant with cancer and neuropathic pain of various origin. Despite the relatively low acute toxicity of cannabinoids they should be avoid in patients with psychotic disorders, pregnant or breastfeeding woman. Cannabinoids prolong a time of reaction and decrease power of concentration that's why driving any vehicles is forbidden. Cannabis side-effects varies and depend from several factors like administrated dose, rout of administration and present state of mind. After sudden break from long-lasting use, withdrawal symptoms can appear, although they entirely disappear after a week or two.

    Full Text Available This study deals with development and optimization of nanostructured lipid carriers (NLCs of candesartan cilexetil (CC for improving its oral bioavailability. From solubility and lipid-water partition studies of CC in various lipids, glyceryl monostearate (GMS and glyceryl monocaprylate were selected as solid lipid and liquid lipid, respectively. NLCs were formulated by hot melt-emulsification-ultrasonication method. A three-factor, three-level Box-Behnken design was used to optimize the independent variables, lipid: drug ratio (X1, solid lipid: liquid lipid ratio (X2 and surfactant concentration (X3. Different batches were prepared and evaluated for responses, particle size (Y1, zeta potential (Y2 and % entrapment efficiency (Y3. Response surface plots and perturbation plots were constructed to study the effect of factors on responses. The optimized formulation containing X1 - 22.47:1, X2 - 7.23:1 and X3 - 1.97% was prepared and evaluated. Observed values for Y1, Y2, and Y3 were found to be closer to the predicted values thus validating the optimization method. Differential scanning calorimetry thermograms of pure drug, GMS and lyophilized drug loaded NLCs indicated complete miscibility of drug into lipids. The release of CC from the NLCs conducted in artificial gastric fluid (pH 1.2 was much higher than in phosphate buffer solution (pH 6.8. The formulated NLCs were found to be more stable at refrigerated condition (5°C ± 3°C as compared with room temperature (25°C ± 2°C/60% RH% ± 5% RH. The use of design approach helped to identify critical formulation parameters in CC loaded NLCs preparation.

  18. Progress of Experimental Study on Treatment of Psoriasis by Chinese Medicinal Monomer and Single or Compound Recipe in Chinese Materia Medica

    2007-01-01

    Psoriasis is a common,chronic,recurrent inflammatory skin disorder whose etiology is still unknown.It is believed that a multiple-gene inheritance is involved and it also involves various factors such as immunity,inflammation,cell proliferation,apoptosis,neural media,etc.Since cytokines are key mediators in inflammation,a number of Chinese medicines(CMs)have been reported to have certain antagonist effects on pro-inflammatory cytokines such as tumor necrosis factor-a(TNF-α),platelet active factor(PAF)and interleukin-8(IL-8).Some researches on CMs have made significant breakthroughs in psoriasis by intervening with cytokines.Abnormalities with keratinocyte proliferation and apoptosis are considered to be present in patients with psoriasis and a number of studies show that the mechanism of CMs on psoriasis may be through the inhibition of the keratinocyte proliferation and induction of apoptosis.Other studies also show that the inhibition of fibroblast-secreted cytokines could regulate keratinocyte proliferation and differentiation and reduce the level of Calcitonin gene-related peptide(CGRP)in plasma and in lesions so as to slow down the process of inflammation and proliferation in psoriasis.The most commonly used models for psoriasis are the scaled tails or the vaginal epithelium of mice in China.They were used to observe the histopathological changes after the model mice were treated with CMs with the inhibition on the mitosis of vaginal epithelium or promotion of granular layer in rat tail taken as the indices of clinical efficacy.A variety of signs occur in psoriasis patients with TCM blood-stasis syndrome type and the effect of CMs in activating blood circulation to remove blood stasis on psoriasis suggested that the mechanism of CMs may be partially correlated to hemorrheology and microcirculation.Along with the continuous development of the biosciences,some TCM theories for psoriasis have been confirmed by laboratory studies.However,the exploration into

    To understand and develop Chinese materia medica is a matter not only dealing with progresses of science and technology but also with that of bio-science. In the area of life-science, the activity of human life-science is the most complicated one which is far away to be satisfactorily explained with existing knowledge of science. Therefore, it is much insufficient to explain and qualify the interreaction between Chinese materia medica and process of human-life with knowledge of general science and non-fully developed bioscience. To understand and develop Chinese materia medica is also matter dealing with many issues of social science. In terms of epistemology, it is necessary to consider how to make some social adjustment for scientific practice and drug registration of Chinese materia medica, under precondition of balance among science, life-science, technology, ethics and philosophy.

    Sakae Miki said Classified Emergency Materia Medica had been the dominant standard of herbology throughout Joseon Dynasty, and that Compendium of Materia Medica had only been accepted so lately that a few books used herbological result of it in the late Joseon Dynasty. But according to Visiting Old Beijing Diary written by Munjoong Seo in 1690, Compendium of Materia Medica was in fact introduced before the year 1712, the year Miki Sakae argued to be the year Compendium of Materia Medica was accepted to Joseon officially. Now, we can assume that the introducing year of Compendium of Materia Medica was faster than Miki Sakae's opinion by the following reasons; the effort of Joseon government and intellectuals to buy new books of Ming & Ching; the publishing year of the book for living in countryside regarded as the first citing literature of Compendium of Materia Medica. And the True Records of the Joseon Dynasty and many collections written by intellectuals in the 18th century show that the herbological knowledge from Compendium of Materia Medica had already spread to the corners of Joseon Dynasty. Thus we can make the following assumption: Classified Emergency Materia Medica and Compendium of Materia Medica had coexisted in the late Joseon Dynasty. Sakae Miki suggested 6 examples which used Compendium of Materia Medica in the late Joseon Dynasty. I reviewed two of them in this paper, Essentials of Materia Medica & Handbook of Prescriptions from Materia Medica. Essentials of Materia Medica quoted Compendium of Materia Medica briefly focusing clinical use, and Handbook of Prescriptions from Materia Medica also re-compiled Compendium of Materia Medica to practical use according to the form of Treasured Mirror of Eastern Medicine. It means that the results of Compendium of Materia Medica have been used positively, based on the herbology of materia medica from countryside. From this point of view, the hyphothesis there weren't any herbological progress after accepting

    DNA barcodes have been increasingly used in authentication of medicinal plants, while their wide application in materia medica is limited in their accuracy due to incomplete sampling of species and absence of identification for materia medica. In this study, 95 leaf accessions of 23 species (including one variety) and materia medica of three Pharmacopoeia-recorded species of Angelica in China were collected to evaluate the effectiveness of four DNA barcodes (rbcL, matK, trnH-psbA and ITS). Our results showed that ITS provided the best discriminatory power by resolving 17 species as monophyletic lineages without shared alleles and exhibited the largest barcoding gap among the four single barcodes. The phylogenetic analysis of ITS showed that Levisticum officinale and Angelica sinensis were sister taxa, which indicates that L. officinale should be considered as a species of Angelica. The combination of ITS + rbcL + matK + trnH-psbA performed slight better discriminatory power than ITS, recovering 23 species without shared alleles and 19 species as monophyletic clades in ML tree. Authentication of materia medica using ITS revealed that the decoction pieces of A. sinensis and A. biserrata were partially adulterated with those of L. officinale, and the temperature around 80 °C processing A. dahurica decoction pieces obviously reduced the efficiency of PCR and sequencing. The examination of two cultivated varieties of A. dahurica from different localities indicated that the four DNA barcodes are inefficient for discriminating geographical authenticity of conspecific materia medica. This study provides an empirical paradigm in identification of medicinal plants and their materia medica using DNA barcodes.

    Full Text Available ABSTRACT Objective: to verify causes of inactivity in the Home Delivery Medicament Program, as referred by users from a Primary Health Care Service in São Paulo, comparing them to the causes registered in the program and analyzing them in the theoretical model Concept of Access to Health. Methods: cross-sectional study, interviewing 111 inactive users; and documentary study in the program records. Results: half of the users did not know the condition of inactivity. Discrepancies were found between the user's and the program's information, observing different levels of agreement: Absence of physician and administrative staff member 0%; Transfer to other service 25%; Death 50%; Option to quit 50%; Address change 57% and Change in therapeutic schedule 80%. The users' feeling of accepting the program was observed. In the health access concept, inactivity can be explained in the information dimension, in the degree of asymmetry between the patient's and the health professional's knowledge, identified through the indicators: education, knowledge and information sources. Conclusions: due to the low education level, the user does not assimilate the information on the steps of the program flowchart, does not return for the assessment that guarantees its continuity. Consequently, (she stops receiving the medication and spends a long time without treatment, increasing the cardiovascular risk of hypertensive (92% of the sample, diabetic (44% and dyslipidemic patients (31%.

    Successful treatment of apical periodontitis is dependent on the elimination of the infective microflora from the necrotic root canal system. Antimicrobial irrigating solutions and other locally used disinfecting agents and medicaments have a key role in the eradication of the microbes. While most if not all presently used disinfecting agents rapidly kill even the resistant microbes when tested in vitro in a test tube, the effectiveness of the same agents is clearly weaker in the in vivo conditions. Recent studies have given valuable information about the interaction of endodontic disinfecting agents with dentin and other compounds present in the necrotic root canal. As a result of such interactions the antimicrobial effectiveness of several of our key disinfectants may be weakened, or even eliminated under certain circumstances. Different disinfectants show different sensitivity to the action by the various potential inactivators, such as dentin, serum proteins, hydroxyapatite, collagen derived from different sources, and microbial biomass. This review is a summary of our present knowledge of the mostly negative interactions between endodontic disinfecting agents and the various compounds present in the root canal environment.

    Alfalfa (Medicago sativa L.) is an important crop worldwide whose cropping in acid soils is hampered by the poor nodulation and yield commonly attributed to the sensitivity of its endosymbionts to acid pH. In this work, we isolated several acid-tolerant strains from alfalfa nodules in three acid soils in northwestern Spain. After grouping by RAPD fingerprinting, most strains were identified as Ensifer meliloti and only two strains as Ensifer medicae according to their 16S-23S intergenic spacer (ITS) sequences that allowed the differentiation of two groups within each one of these species. The two ITS groups of E. meliloti and the ITS group I of E. medicae have been previously found in Medicago nodules; however, the group II of E. medicae has been only found to date in Prosopis alba nodules. The analysis of the nodC gene showed that all strains isolated in this study belong to the symbiovar meliloti, grouping with the type strains of E. meliloti or E. medicae, but some harboured nodC gene alleles different from those found to date in alfalfa nodules. The strains of E. medicae belong to the symbiovar meliloti which should be also recognised in this species, although they harboured a nodC allele phylogenetically divergent to those from E. meliloti strains. Microcosm experiments showed that inoculation of alfalfa with selected acid-tolerant strains significantly increased yields in acid soils representing a suitable agricultural practice for alfalfa cropping in these soils.

    By Zhuang materia medica, it refers to application of medicines under the instructions of medical theory of Zhuang ethnic group. By studying the pronunciation of the Zhuang language for the terms "zhu yu", "bai jiu", and "mi gu" included in the shan hai jing nan shan jing (The Classic of Southern Mountain in Classic of Seas and Mountains) carried out by the Zhuang scholar Qin Bao-lin, it was concluded that the Zhuang minority already applied medicines early in the pre-Qin period. Through extensive cultural communication in different regions in the Wei-Jin-Southern-Northern Dynasties, the medicinal experiences of the Zhuang ethnic group appeared in ancient literature. The antidotes in Zhou hou fang (Handbook of Prescriptions for Emergency), for instance, were mostly coming from the Southern Ridge area. Since the Sui-Tang Dynasties, many materia medica recorded in the herbal works and regional gazetteers, and Annals such as the Guangxi Annals, Gazetteer of Nanning County, and Gazetteer of Liuzhou County, Gazetteer of Binzhou County etc., also carry medicines such as Cinnamom twigs and bark, and mangosteen etc., which are similar to those of the Zhuang medicines. In the Republican period, many manuscripts of Zhuang medicines appeared. After 1949, many institutions of Zhuang medicine were set up successively, including The Nanning Medical Institute, The Medical Institute of Wuzhou, The Medical Institute of Guilin. Systematic researches were also done, with publication of a series of works on Zhuang materia medica. Reformation of part of the prescription forms of Zhuang medicine were also accomplished.

    Introduction Calcium Hydroxide (CH) is one of the most commonly used intracanal medicaments which can be used with various vehicles. Aim The aim of this in vitro study was to evaluate the effect of three CH based intracanal medicaments on the apical sealing ability of AH Plus – guttapercha obturation. Materials and Methods Crowns of 100 extracted single rooted human teeth were sectioned at the Cemento-Enamel Junction (CEJ) to a standardized length. The root canals were instrumented upto ISO size 40 using step back technique and the specimens were randomly divided into two control and four experimental groups. The control groups were not medicated. Specimens in positive control group (Group I) were obturated with guttapercha without placing sealer and in negative control group (Group II) were obturated with guttapercha and AH Plus sealer. Among the experimental groups, specimens of Group III were not medicated while groups IV, V and VI were medicated with CH-saline, CH-2% Chlorhexidine (CHX) and Vitapex respectively for a period of 14 days. The medicaments were removed from the specimens and the teeth were obturated with AH Plus sealer and guttapercha using lateral compaction technique. The specimens were immersed in India ink dye, demineralized and diphanized. The extent of dye penetration was assessed using a 10X stereomicroscope. Data obtained was statistically analyzed by one-way ANOVA (p<0.05) followed by Post-hoc Tukey test. Results Amongst the three CH medicaments, CH-2% CHX when used as an intracanal medicament showed a significantly higher microleakage as compared to the other groups with p<0.001. The microleakage values between the remaining groups were not statistically significant. Conclusion Under the conditions of this study it was concluded that all groups with or without intracanal medicament showed apical leakage. The vehicle used to carry CH may significantly influence the apical sealing ability of guttapercha – AH Plus obturated canals. PMID

    According to archaeological discoveries, humans began to make use of marine natural resources early in the Palaeolithic era. In the Spring and Autumn period and Warring States period, they began to use marine life as medicines and also had simple cognitions on their efficacy and processing. In the Qin and Han dynasties, people further deepened the understanding of the marine Chinese materia medica and created prescriptions making use of marine drugs. In the Tang and Song period, the number of marine Chinese materia medica species and corresponding prescriptions apparently increased. The cognitions of the property, flavor, efficacy as well as the compatible principle of marine Chinese materia medica was further deepened and the scope of their treatment also significantly expanded. In the Ming and Qing dynasties, the cognition of the marine Chinese materia medica was mainly the conclusions of the previous experience. After the founding of the People's Republic of China (PRC), with the development of science and technologies, the ability of exploiting and utilizing the marine Chinese materia medica by people dramatically increased, and the species of marine Chinese materia medica reached more than one thousand. However, the development of marine Chinese materia medica is confronted with new problems; although the number of species of marine Chinese materia medica increased, the understanding of their property and flavor is obviously lagging behind, which seriously affects the clinical application of marine Chinese materia medica.

    Summary The volatile and flavonoid compositions of the peel of Citrus medica L. var. Corsican fruits cultivated in Corsica were studied according to the maturity of the citron fruits measured using growing degree-days. Quantitative variation with the stage of development of the fruit was observed using gas chromatography, gas chromatography-mass spectrometry, and liquid chromatography-mass spectrometry/mass spectrometry. Thirty volatile compounds were identified in the peel essential oil. Limonene and γ-terpinene were the major compounds. The volatile compositions of commercial citron liqueurs were also characterized by high amounts of monoterpene hydrocarbons with the same two major components. The main flavonoid components of citron fruits and derived liqueurs were rutin and neohesperidin. This chemical characterization can be used for quality assessment of food products from C. medica var. Corsican. PMID:27904313

    2006-11-01

    Full Text Available Screening experiments using 25-1 fractional factorial design showed that pH, temperature, and extracting time were the main factors affecting the amount and quality of extracted pectin from Citrus medica Linn. Optimum condition of pectin extraction was studied using central composite design (CCD. Mathematical models relating pH, temperature and extracted time to amount of extracted pectin, equivalent weight, methyl content and anhydrogalacturonic acid content were established. Based on the mathematics models, the condition of pH 2, 100ºC and 105 min was found to be the optimum conditions for pectin extraction from Citrus medica Linn. Mathematical and experimental results were verified. The use of extracted pectin as a gelling agent in pineapple jam revealed no significant difference in gel consistency compared to that of commercial pectin grade 150 (p>0.05. However, the commercial pectin had a higher liking score on the spreadability, texture and overall liking. As a stabilizer in chocolate pasteurised milk, 0.2% of the extracted pectin was required to prevent precipitation of chocolate powder with the similar viscosity obtained from 0.06% κ-carageenan

    Chinese meteria medica (CMM) chain is a long-span chain covering agriculture which mainly depends on the forces of nature as well as high-tech CMM industry, CMM expertise industry and fast developing CMM circulation industry. Imbalance among the development of these industries produces bottlenecks and hinders the operation of the entire production chain. After analyzing the structure of Chinese meteria medica industrial chain from the perspective of national economy industry, three industry classifications and differentiation of factor intensity, we conclude that the complex structure of CMM industry chain is attributable to these three aspects. And the complexity is mainly shown at complex industry, varied product types, different coordination of various industrial sections and different technical growth speed of varied industry. We propose that structural complexity is the natural property of the chain, which is the main reason of industry sector development imbalance and bottleneck. Results of this research could provide theoretical analysis for future research on the coordination of industrial chain and the efficiency of resource allocation.

    Using Chinese Materia Medica (CM) as injections is an innovation that is proving effective in extensive clinical use in Mainland China. However, recent reports have focused on adverse reactions, ignoring the considerable successes of these preparations. In order to achieve balance in the media and in the minds of the public, we suggest the first step is to clarify the concepts of and differences between adverse drug reactions (ADR) and adverse events (AE) for all concerned-the public, medical practitioners, government officials, and lawmakers. Second, the State Food and Drug Administration should raise the requirements for Chinese Materia Medica Injection (CMI) registration and license approval and emphasize the importance of evidence-based CMI development and evidence-based CMI license approval. Thirdly, drug companies and institutions should reinforce basic research about the quality control of herbs and CMI-drug interactions. Fourth, the Government should clarify the legal responsibilities for CMI approval agencies, CMI developers, medical doctors, and patients. Fifth, the medical association and Government should enhance training for health care professionals concerning the usage of CMIs. And finally sixth, State Food and Drug Administration should monitor the content and quality of the directions for use of CMI.

In Morocco, alfalfa is usually grown in marginal soils of arid and semi-arid regions frequently affected by drought, extremes of temperature and soil pH, soil salinity and heavy metals, which affect biological nitrogen fixing ability of rhizobia and productivity of the host. This study examines phenotypic diversity for tolerance to the above stresses and genotypic diversity at Repetitive Extragenic Pallindromic DNA regions of Sinorhizobium nodulating alfalfa, sampled from marginal soils of arid and semi-arid regions of Morocco. Results RsaI digestion of PCR amplified 16S rDNA of the 157 sampled isolates, assigned 136 isolates as S. meliloti and the rest as S. medicae. Further phenotyping of these alfalfa rhizobia for tolerance to the environmental stresses revealed a large degree of variation: 55.41%, 82.16%, 57.96% and 3.18% of the total isolates were tolerant to NaCl (>513 mM, water stress (-1.5 MPa, high temperature (40°C and low pH (3.5, respectively. Sixty-seven isolates of S. meliloti and thirteen isolates of S. medicae that were tolerant to salinity were also tolerant to water stress. Most of the isolates of the two species showed tolerance to heavy metals (Cd, Mn and Zn and antibiotics (chloramphenicol, spectinomycin, streptomycin and tetracycline. The phenotypic clusters observed by the cluster analysis clearly showed adaptations of the S. meliloti and S. medicae strains to the multiple stresses. Genotyping with rep-PCR revealed higher genetic diversity within these phenotypic clusters and classified all the 157 isolates into 148 genotypes. No relationship between genotypic profiles and the phenotypes was observed. The Analysis of Molecular Variance revealed that largest proportion of significant (P Conclusion High degree of phenotypic and genotypic diversity is present in S

    Background: Ala-al-din abu Al-Hassan Ali ibn Abi-Hazm al-Qarshi al-Dimashqi, known as Ibn al-Nafis (1210-1288 AD), was a Muslim Syrian physician primarily famous for being the first to describe the pulmonary circulation of the blood. The most voluminous of his books is Alshamel fi Sana’at tebbi’at, which is a comprehensive medical encyclopedia. It comprised 300 volumes of notes, from which only 80 volumes are published. His writings are cataloged in many libraries around the world. The aim of this review article, as a tribute to Ibn al-Nafis, was to introduce his valuable but neglected encyclopedia of Materia Medica. Methods: Ibn al-Nafis’ traditional approach in his “Alshamel fi Sana’at tebbi’at” book is studied in the present article. Results: Alshamel fi Sana’at tebbi’at covers three branches of knowledge. The first category is devoted to theoretical traditional medicine. The second is in four sections where much of it is not available yet. The third category is on Materia Medica covering the aspect of Unani medicine, from which only 28 volumes of the comprehensive book on the traditional medicine have been found so far. The latter, introduces mono-ingredient medications in alphabetical order. Each chapter, in several parts, is dedicated to the botanical characteristics and nature of each mono-ingredient medication. In addition, this book explains traditional pharmacokinetic of every single medication for each human body organs. Conclusion: Based on pharmaco-mechanistic perspective on Alshamel fi Sana’at tebbi’at, it could be considered as the main reference book on traditional medicine and pharmacy, worthy of revival.

    Activation of the brain angiotensin II type 1 receptor (AT1R) triggers pro-oxidant and pro-inflammatory mechanisms which are involved in the neurobiology of bipolar disorder (BD). Candesartan (CDS) is an AT1 receptor antagonist with potential neuroprotective properties. Herein we investigated CDS effects against oxidative, neurotrophic inflammatory and cognitive effects of amphetamine (AMPH)-induced mania. In the reversal protocol adult mice were given AMPH 2 mg/kg i.p. or saline and between days 8 and 14 received CDS 0.1, 0.3 or 1 mg/kg orally, lithium (Li) 47.5 mg/kg i.p., or saline. In the prevention treatment, mice were pretreated with CDS, Li or saline prior to AMPH. Locomotor activity and working memory performance were assessed. Glutathione (GSH), thiobarbituric acid-reactive substance (TBARS) and TNF-α levels were evaluated in the hippocampus (HC) and cerebellar vermis (CV). Brain-derived neurotrophic factor (BDNF) and glycogen synthase kinase 3-beta (GSK-3beta) levels were measured in the HC. CDS and Li prevented and reversed the AMPH-induced increases in locomotor activity. Only CDS prevented and reversed AMPH-induced working memory deficits. CDS prevented AMPH-induced alterations in GSH (HC and CV), TBARS (HC and CV), TNF-α (HC and CV) and BDNF (HC) levels. Li prevented alterations in BDNF and phospho-Ser9-GSK3beta. CDS reversed AMPH-induced alterations in GSH (HC and CV), TBARS (HC), TNF-α (CV) and BDNF levels. Li reversed AMPH-induced alterations in TNF-α (HC and CV) and BDNF (HC) levels. CDS is effective in reversing and preventing AMPH-induced behavioral and biochemical alterations, providing a rationale for the design of clinical trials investigating CDS׳s possible therapeutic effects.

    Nature of Chinese materia medica is the nucleus in the theory of Chinese material medica, according to the recognition of Traditional Chinese Medicine, which is the character of the drug related on curative effect. Nature and efficacy of a drug is through the medical material, then, physical environment, including the temperature, humidity, atmospheric water, wind, topography, soil, micro-organism, and so on, influence the growth and development of the medical meterial. In this paper, we researched the explanation on nature of Chinese materia medica in the medical books of past dynasties, combined with the modem research, analyzed the relationship between generative reception and physical environmental factors, and discussed the effect of physical environmental factors on nature of Chinese materia medica. We indicated that the formation of Chinese materia medical nature is that the drug receptive the change of physical environmental factors, and resulted by the synthetic action of the factors, such as climate, soil, biology, topography, etc.

    Authentication of Chinese Materia Medica (CMM) decoction dregs is important for ensuring the efficacy and safety of CMM when they are used in decoction. If someone got worse or poisoned after taking a decoction while the formula is appropriate, the authentication of CMM dregs is the effective method to explore the reasons. Therefore, a systematic study on the authentication of CMM dregs was carried out. In this study, two pairs of easily confused CMM dregs, Fenge (Puerariae Thomsonii Radix) and Shanyao (Dioscoreae Rhizoma), Dihuang (Rehmanniae Radix) and Huangjing (Polygonati Rhizoma), which mostly comprise storage tissues, were investigated by comparing the morphological and microscopic characteristics. Fenge and Shanyao contain abundant starch granules. After decoction their dregs were hard, nonstarchy and horn-like. Fully gelatinized starch granules were found in the powder of Fenge dregs while incompletely gelatinized starch granules were occasionally found in the Shanyao dregs. In contrast, Dihuang and Huangjing contain water-soluble sugars. After decoction, their dregs were hard and brittle. Their parenchymatous cells were shrunken and unknown crystals were found under microscope. Hence, the morphological and microscopic characteristics of CMM before and after decoction were different, and different changes in the CMM dregs can be illustrated by the different nature of their ergastic substance. These differences could be used to authenticate CMM dregs.

    Many important drugs in the Chinese materia medica (CMM) are known to be toxic, and it has long been recognized in classical Chinese medical theory that toxicity can arise directly from the components of a single CMM or may be induced by an interaction between combined CMM. Traditional Chinese Medicine presents a unique set of pharmaceutical theories that include particular methods for processing, combining and decocting, and these techniques contribute to reducing toxicity as well as enhancing efficacy. The current classification of toxic CMM drugs, traditional methods for processing toxic CMM and the prohibited use of certain combinations, is based on traditional experience and ancient texts and monographs, but accumulating evidence increasingly supports their use to eliminate or reduce toxicity. Modern methods are now being used to evaluate the safety of CMM; however, a new system for describing the toxicity of Chinese herbal medicines may need to be established to take into account those herbs whose toxicity is delayed or otherwise hidden, and which have not been incorporated into the traditional classification. This review explains the existing classification and justifies it where appropriate, using experimental results often originally published in Chinese and previously not available outside China.

    Full Text Available Soxhlet extraction technique is widely employed for the extraction and separation of chemical constituents in the medicinal plants. Citrus medica L commonly called as Citron belongs to family Rutaceae, is a slow-growing shrub. It is mainly cultivated for the production of edible fruits which are sour in taste like lime and lemon and the main content of a citron fruit is the thick rind, which is very adherent to the segments. From the phytochemical analysis the peel extract is rich source of phenols, flavonoids and alkaloids. The objective of present work is to develop a modelling equation for quercetin, rutin and kaempferol and the crude extract obtained by soxhlet extraction was further purified by solvent-solvent extraction and Column chromatography. Extraction was carried out by 80% methanol as a solvent Soxhlet extractor. Soxhlet extraction with methanol was carried out with varying time intervals, to evaluate modelling equation. The proposed modelling equation was Es = 0.0849(t + 7.0286 for Quercetin and Es = 0.0912(t + 25.971 for rutin, and Es = 0.0267(t + 7.3714 for Kaempferol. High yield was obtained for 180min of Soxhlet extraction with 80% methanol. Yield of quercetin, rutin and kaempferol after solvent-solvent extraction and column chromatography was 22.6µg/ml, 43.7µg/ml and 10.8µg/ml respectively. The proposed model showed good agreement with the experimental data.

    Endodontic regeneration treatment of necrotic immature teeth has gained popularity in recent years. The approach suggests a biological alternative to induce a continuous root development. In this project, three in vitro experiments were conducted to investigate the effect of three medicaments used in endodontic regeneration on mechanical properties and chemical structure of radicular dentin. In the first experiment, we investigated longitudinally the effect of medicaments on the indentation properties of the root canal surface of immature teeth using a novel BioDent reference point indenter. A significant difference in the majority of indentation parameters between all groups was found after one-week and one-month application of medicaments (p double antibiotic paste (DAP) > control > calcium hydroxide [Ca(OH)2]. The four-week exposure of dentin to TAP and DAP caused 43% and 31% increase in total indentation distance outcome, respectively. In the second experiment, we investigated longitudinally the effect of medicaments on the chemical structure of immature radicular dentin by measuring the phosphate/amide I ratios of dentin using Attenuated Total Reflection Fourier Transform Infrared Spectroscopy. Phosphate/amide I ratios were significantly different between the four groups after one week, two weeks and four week application of medicaments (p untreated dentin > DAP-treated dentin > TAP-treated dentin. In the third experiment, we investigated longitudinally the effect of medicaments on root fracture resistance and microhardness of radicular dentin. For the microhardness, the two-way interaction between group and time was significant (pintegrity of the superficial radicular dentin and significantly affected the indentation properties of the root canal surface. Furthermore, the three month intracanal application of medicaments significantly reduced the fracture resistance of roots.

    The evaluation of permeability in biopharmaceutics classification system of Chinese materia medica (CMMBCS) requires multicomponent as a whole in order to conduct research, even in the study of a specific component, should also be put in the multicomponent environment. Based on this principle, the high content components in Gegen Qinlian decoction were used as multicomponent environmental impact factors in the experiment, and the relevant parameters of intestinal permeability about puerarin were measured with using in situ single-pass intestinal perfusion model, to investigate and evaluate the intestinal permeability of puerarin with other high content components. The experimental results showed that different proportions of baicalin, glycyrrhizic acid and berberine had certain influence on intestinal permeability of puerarin, and glycyrrhizic acid could significantly inhibit the intestinal absorption of puerarin, moreover, high concentration of berberine could promote the absorption of puerarin. The research results indicated that the important research ideas of permeability evaluation in biopharmaceutics classification system of Chinese materia medica with fully considering the effects of other ingredients in multicomponent environment.

    To provide a better service for senior health care, we summarized screening studies of traditional Chinese anti-aging materia medica (TCAM). We collected and analyzed literature of TCAM screening studies using the lifespan test and animal models of aging from 1984 to 2012. We found 26 screening methods for TCAM, and 153 single herbs or active ingredients of TCAM that have been screened out during the past 28 years. The cell lifespan test, the fruit fly lifespan test, and D-galactose aging model were the most widely used and intensively studied screening methods. However, the method for establishing the D-galactose aging model needs to be standardized, and the D-galactose aging model cannot completely be a substitute for the normal aging mouse model. Great success has been achieved in screening studies in TCAM. To further improve screening studies in TCAM, we suggest that the D-galactose aging model be incorporated into the lifespan test in the New Drugs of Traditional Chinese Medicine Research Guide.

    By investigating the mainstream works of herbal classics of successive ages, it is found that adulteration of Chinese materia medica appeared early in ancient China. The main methods of adulteration was producing fraud medicines in the Northern-Southern Dynasties, fake medicines began to appear in the Tang Dynasty, and status of adulteration of Chinese materia medica ran unchecked since the Ming and Qing Dynasty. By statistics, there were 76 kinds of adulteration varieties before the Republican period. The main varieties were precious drugs, animal drugs and artifacts. Commonly methods used in the process included forging and adulterating, dealing with 11 kinds and 68 kinds respectively. Adulteration probably lead to the result of imposing the changes of the used medicinal parts of Herba Pogostemonis; Radix Aconiti Lateralis prepared by adding salt, Radix Angelica Sinensis processed by wine, and Radix Astragalis seu Hedysaris processed with bee honey. However, the root cause of adulteration in Chinese materia medica was the dissociation of professional physician and pharmacist, resulting in the ignorance of medical practitioners became unable to recognize Chinese materia medica; and the immorality of medicinal merchants. Besides, rating the quality of materia medica based on its producing areas without differentiating the false from the genuine may also contribute to this result passively.

    Zhengleibencao (Classified Materia Medica) had been formed into several kinds of edition systems during its dissemination, among which there was the edition system of Daquanbencao (Complete Collection of Materia Medica). Daquanbencao was originally carved in the Jin dynasty, thereafter it was re-carved in the Yuan, Ming and Qing dynasties so as to form a series of editions such as the edition of Zhenyou in the second year of the Jin dynasty; the edition of the Zongwenshuyuan college in Dade renyan year of the Yuan dynasty; the WANG Qiu's carved edition of Shangyitang hall in the Ming dynasty; the carved edition of Jishanshuyuan, the Jishang mountain college in the Ming dynasty, the reprinted edition of PENG Duan-wu in the Ming dynasty, the supplementary edition of YANG Bi-da in the Qing dynasty;, and the carved edition of KE Feng-shi in the Qing dynasty. Among all the editions, Chongkanjingshizhengleidaquanbencao (Reprinted Classified Daquan Materia Medica from Historical Classics) was the representative one. As a representative of the above editions, the carved edition of WANG took the edition of the Zongwenshuyuan college of the Yuan dynasty as the original edition, but the images picture of materia medica adopted from the edition of Zhenghebencao (Materia Medica of the Zhenghe era).

    Based on the current shortage of genuine/false authentication and quality evaluation in the molecular identification, and the weak functional gene research in the establishment of two-dimensional molecular markering methods for Chinese materia medica, the authors proposed a new method, the bimolecular marking methods (BIMM) for Chinese materia medica, combining DNA marker and metabolomics marker, that could simultaneously research the species and quality differences at the molecular level at the present stage. The authors introduced the concept, principle, methods, and technical process of BIMM, and summarized the technical advantages in this paper. Meanwhile, the application of BIMM in the identification of multiple sources of Chinese materia medica, years-identification, different locations, elite germplasm research, discovery of new drugs resources, protection of new varieties was also discussed. As a supplement of two-dimensional molecular markering method for Chinese materia medica, BIMM would not only expand connotation of identification of Chinese materia medica but also provide another effective way for quality evaluating.

    Many models of diabetic nephropathy have been reported. However, it is rare that the characteristic findings of severe human diabetic nephropathy, such as diffuse, nodular, and exudative lesions, are all detected in one model mouse. Previously, we reported that MAFA-deficient and beta cell-specific MAFK-overexpressing hybrid transgenic (Mafa(-/-)Mafk (+)) mice develop diabetes mellitus and, after uninephrectomy, demonstrate these characteristic lesions. In this study, we administered TCV-116 (candesartan cilexetil) to Mafa(-/-)Mafk (+) mice after uninephrectomy and examined whether TCV-116 ameliorated the diabetic nephropathy. We also evaluated the utility of these mice as a model for developing treatments for diabetic nephropathy. We performed uninephrectomy of the Mafa(-/-)Mafk (+) mice at 8 weeks old. We then divided these mice into two groups as follows: 1) an untreated group and 2) a group treated with TCV-116 at 5 µg/g/day from 10 to 20 weeks. TCV-116 treatment did not affect serum glucose levels. However, in the treated group, urinary protein excretion, mesangial matrix expansion, enlargement of the kidney, and glomerular surface area were all improved relative to untreated mice. Oxidative stress is known to be increased in diabetic nephropathy and to be suppressed by TCV-116. The urinary level of 8-OHdG, an oxidative stress marker, at 20 weeks was lower in the TCV-116-treated group than in the untreated group. From these results, we concluded that the Mafa(-/-)Mafk (+) mouse is a useful model to analyze diabetic nephropathy and a useful tool for the development of new drugs to treat diabetic nephropathy.

  17. European Materia Medica in Historical Texts: Longevity of a Tradition and Implications for Future Use

    2010-01-01

    Recent research in the area of new drug discovery has shown the continued promise of looking to natural products for bioactive compounds. Researchers have thus turned to traditional medicine, which is still used widely throughout the world and increasingly in industrialized countries as well, to provide clues as to which products to investigate. The oral traditions on which much of this medical knowledge rests, however, are unstable, prompting researchers to turn to textual sources for potential drugs. This study uses Mediterranean/European medical texts from the 5th century BC to the 19th century A.D. to compile a list of the most commonly used “simples” – or single action drug substances – used in therapeutics in traditional European medicine. It finds that traditional European materia medica was based on a Dioscordean tradition that lasted through the 19th century with remarkably little variation, but is significantly different from the present-day herbal pharmacopoeia as represented by the National Institutes of Health. The most prominent simples of that tradition can thus provide clues to further bioactive compounds that have not as of yet been fully exploited for their potential, but were clearly of great use in the past.

    2011-01-01

    The objective of this paper was to investigate the effects of a Chinese Materia Medica variant -Fubao Danggui Jiao (FDJ)-on experimental endometriosis. An endometriosis model was created by virtue of auto-transplantation of endometrial tissue onto rats' abdominal walls. The implants were allowed to grow for 30 days until the successful completion of the model. After that, forty endometriotic rats were randomly divided into four study groups and given different treatments: (1) negative control group (water, 2ml/kg, per os); (2) FDJ-A group (FDJ, 2ml/kg, per os); (3) FDJ-B group (FDJ, 4ml/kg, per os); (4) Danazol group (70mg/kg, per os). After 30 days with treatments, the volumes of endometriotic implants in each rat were measured. The implants and normal uterine horns were removed for routine histological examination. FDJ caused significant decreases in volumes of the surviving endometriotic implants, with two different doses having statistically equivalent effects. Upon histological examination, FDJ was observed to cause regression of epithelium and stroma of endometriotic implants. FDJ had revealed promising therapeutic effects on endometriosis.

    Bi-directional regulation is referred to a balancing effect of both acu-moxibustion and Chinese materia medica interventions when the human body is experiencing a hyperactivity or hypoactivity due to abnormal intrinsic or external factors. In the present paper, the authors analyze their identical and different characteristics from: 1) definition; 2) characters of regulative effects of acu-moxibustion therapy: A) differentiation of meridian and zangfu-organs being the basis of treatment, B) four factors (acupoint-location, body's functional state, acupoint-formula and needle-manipulation techniques) dependant, C) entirety regulation, and D) centrotaxis modulation; 3) characters of Chinese materia medica intervention: including a) correspondence between the drug property and the syndrome being the basis of the regulative effect, b) multi-factors [components (antagonist and agonist), combination, dosages and processing quality of Chinese materia medica, and functional state of the human body] dependant, c) entirety regulation, and d) both centrotaxis and deviation adjustment. In one word, the bi-directional regulation effect is one of the basic characteristics of both acu-moxibustion and Chinese materia medica in clinical practice, but their basis and modes for inducing effects are different.

    The origin of northern Artemisia argyi recorded in Compendium of Materia Medica(Bencao gangmu) is Fudao(Chinese characters) in Tangyin county, While there is only Fudao(Chinese characters) instead of Fudao(Chinese characters). Whether indeed Fudao(Chinese characters) is Fudao(Chinese characters)? By reviewing the genuine evolution of A. argyi, doing textual research on Fudao(Chinese characters) and combing with field survey data of national census of Chinese Materia Medica resources, this paper concluded that the word Fudao(Chinese characters) firstly emerged in Figure Canon of Chinese Materia Medica(Bencao tujing) of Susong in Song dynasty and was applied in later generations, but the implication was not clear, then emerged both Tangyin and Fudao(Chinese characters) in Compendium of Materia Medica(Bencao gangmu). The place Fudao(Chinese characters) is one of the graves of Bianque, that existed from Shang and Zhou dynasty and never changed until now, the A. argyi of Tangyin was famous from the grave of Bianque in Fudao(Chinese characters), which could infer that Lishizhen considered Fudao (Chinese characters) was Fudao(Chinese characters) indeed, and the origin of northern A. argyi was Fudao(Chinese characters) in Tangyin county.

    OBJECTIVE: The concepts of cold and hot herbal properties in traditional Chinese medicine (TCM), reflecting the efficacy trends of medicinal herbs, have the Fuzzy characteristics. It is suited for the application of Fuzzy mathematics in research of herbal properties. For a comprehensive evaluation of herbal properties, this work constructed and made a practice of the Fuzzy discrimination model regarding the biological performance of Chinese materia medica.METHODS: Firstly, TCM formulas of cold or hot property were employed for setting the reference values and calculating the membership functions of cold and hot Fuzzy sets with Fisher discriminant. Then the model parameters of cold performance function (CPF) and hot performance function (HPF) were acquired. Second, the experimental data from studies on changes in multisystem indicators of animals given the classical cold formula (Sanhuang Fang) and hot formula (Jiangfugui Fang) were collected to calculate CPF and HPF. Then an experiment of administration of hot property herbs, Rougui (Cortex Cinnamomi) and Xianmao (Rhizoma Curculiginis), and cold property herbs, Huangbai (Cortex Phellodendri) and Zhizi (Fructus Gardeniae) to normal animals and animals with glucocorticoid-induced yang-deficiency or yin-deficiency state was designed. The relative changes in animal states were analyzed by the evaluation model to find the way in which herbal properties are represented.RESULTS: The HPF values of biological performance were higher than the CPF values in administration of Rougui to animals of normal (0. 528>0. 221), yang-deficiency (0. 203> -0. 490) and yin-deficiency (1.750 > -0.479) states, and in administration of Xianmao to animals of normal (0. 474> - 1. 601) and yang-deficiency (0. 288 > -1. 923) states, which represented the hot property. The HPF values of biological performance were lower than the CPF values in administration of Huangbai to animals of normal ( - 0. 870< 0.798) and yang-deficiency ( - 0.339<0. 194

    Endodontic lubricants, irrigants and medicaments help prepare and disinfect root canal systems (RCS) but primary and secondary cases involve different microbes and therefore it is unlikely that one protocol will be effective for both case types. Each individual 'solution' or sequence of'solutions' could play a significant role in each case type, but there are no detailed published guidelines in existence. To help inform clinical practice it was decided to undertake a literature review followed by a UK and Republic of Ireland wide audit on current endodontic'solution' usage within dental schools. The literature review was undertaken under the following headings: pre-op oral rinse; file lubricants; root canal irrigants and intracanal medicaments and provides an evidence base for protocol development for both primary and retreatment cases.The audit project and the protocols developed from the findings of both the literature review and audit will be presented in Part 2.

    Abstract Historians of indigenous medicine in colonial India have looked more closely at the changes, reinventions and reformulations of institutions of Ayurveda and Unani than at the cognitive content of the drugs themselves. The few historians who have examined the changing content of indigenous medicines have conceptualised the creation of materia medica of Indian drugs through two tropes: one of circulation (of specific drugs) through epistemological and geographic boundaries and the seco...

    2013-10-18

    A complex extraction system with the use of cloud-point extraction technique (CPE) was developed for sequential isolation of basic and acidic/neutral medicaments from human plasma/serum, screened by HPLC/DAD method. Eight model drugs (paracetamol, promazine, chlorpromazine, amitriptyline, salicyclic acid, opipramol, alprazolam and carbamazepine) were chosen for the study of optimal CPE conditions. The CPE technique consists in partition of an aqueous sample with addition of a surfactant into two phases: micelle-rich phase with the isolated compounds and water phase containing a surfactant below the critical micellar concentration, mainly under influence of temperature change. The proposed extraction system consists of two chief steps: isolation of basic compounds (from pH 12) and then isolation of acidic/neutral compounds (from pH 6) using surfactant Triton X-114 as the extraction medium. Extraction recovery varied from 25.2 to 107.9% with intra-day and inter-day precision (RSD %) ranged 0.88-1087 and 5.32-17.96, respectively. The limits of detection for the studied medicaments at λ 254nm corresponded to therapeutic or low toxic plasma concentration levels. Usefulness of the proposed CPE-HPLC/DAD method for toxicological drug screening was tested via its application to analysis of two serum samples taken from patients suspected of drug overdosing.

    A collection of nodule isolates from Medicago polymorpha obtained from southern and central Portugal was evaluated by M13-PCR fingerprinting and hierarchical cluster analysis. Several genomic clusters were obtained which, by 16S rRNA gene sequencing of selected representatives, were shown to be associated with particular taxonomic groups of rhizobia and other soil bacteria. The method provided a clear separation between rhizobia and co-isolated non-symbiotic soil contaminants. Ten M13-PCR groups were assigned to Sinorhizobium (Ensifer) medicae and included all isolates responsible for the formation of nitrogen-fixing nodules upon re-inoculation of M. polymorpha test-plants. In addition, enterobacterial repetitive intergenic consensus (ERIC)-PCR fingerprinting indicated a high genomic heterogeneity within the major M13- PCR clusters of S. medicae isolates. Based on nucleotide sequence data of an M13-PCR amplicon of ca. 1500 bp, observed only in S. medicae isolates and spanning locus Smed_3707 to Smed_3709 from the pSMED01 plasmid sequence of S. medicae WSM419 genome's sequence, a pair of PCR primers was designed and used for direct PCR amplification of a 1399-bp sequence within this fragment. Additional in silico and in vitro experiments, as well as phylogenetic analysis, confirmed the specificity of this primer combination and therefore the reliability of this approach in the prompt identification of S. medicae isolates and their distinction from other soil bacteria.

The purpose of the present study was to evaluate the biocompatibility of PC as a pulpotomy medicament. Materials and Methods: Thirty premolars that scheduled for extraction for therapeutic reasons were randomly assigned to two experimental groups: ProRoot MTA (PMTA and PC. After isolation and pulp exposure, pulpotomy was carried out and pulps were dressed with PMTA and PC. After 6 months, the teeth were extracted and prepared for histological analysis based on Cox et al. criteria. The data were analyzed by Z-test of proportion with 1% of allowed error. Results: No statistically significant difference was found between the two groups with respect to inflammatory response, soft tissue organization, and dentine bridge formation (P > 0.05. Conclusions: PC was associated with similar favorable biological response to pulpotomy treatment as PMTA. The findings of this study support the idea that PC can be considered a cheaper substitute to MTA.

    For more systematic medical education, Dr. O. R. Avison translated medical textbooks into Korean since he took charge of Jejungwon in 1893. The first book he chose was Anatomy of the Human Body. He, however, failed to see it published after losing its manuscript twice. Instead, Materia Medica Part. I was brought into the world first in 1905, for which he translated Materia Medica and Therapeutics written by John Mitchell Bruce from the U. K. At that time, this book was in widespread use in the English-speaking world as a textbook for pharmacology. It is also assumed that Avison used it as a textbook for his classes in Canada before coming to Korea. For the publication of Materia Medica Part. I, Avison did not translate Bruce's original text in full, but translated only the selected passages. He followed a principle of using Korean alphabets (Hangeul) only, but in combination with Chinese characters, if necessary. He put pharmacological terms into existing Korean equivalents or newly coined words, but also borrowed many from Japanese terms. That's because Japan moved faster to introduce Western medicine than Korea did, so that many pharmacological terms could be defined and arranged more systematically in Japanese. Moreover, Japan took such a favorable stance in the state of international affairs that many of Japanese-style terms could be introduced into Korea in most fields including medicine. By translating Materia Medica Part. I in cooperation with his disciple KIM Pilsoon after Gray's Anatomy of the Human Body, Avison tried to lay groundwork for providing medical education in Korea based on the British-American medicine. It is assumed that he took an independent stance in selecting and translating Western medical textbooks on his own rather than simply accepting the existing Chinese translation of Western medical textbooks. Despite all his efforts, he might find it difficult to translate all the Western medical terms into Korean within a short period of time

    Toxicity of Chinese materia medica (CMM) is an important part of Chinese herbal nature theory. In clinical application, the dosage, time limitation and compatibility of CMM is mainly determined by toxicity. At present, there is no uniform toxicity classification standard for the evaluation of Chinese herbal toxicity. Therefore, it is significant to research toxicity classification of CMM. The current situation of toxicity classification of CMM is reviewed in this paper, and proposed research thoughts are as follows: the measurement of toxicity parameters, the confirmation of poisoning target organs, the investigation on toxic mechanism by serum pharmacology and toxicokinetics, the comprehensive evaluation on toxicity based on quantitative theory.

    For thousands of years, the natural resource for Chinese materiamedica has been the foundation of the traditional Chinese medicine industry, which provides abundant medicine for human. In recent years, increasing demands and irrational exploitation led to a lot of problems such as rapid decrease of traditional Chinese herbs reserves, low quality of medicine and dismishing traditional cultures. These restricted the development of the traditional Chinese medicine. To solve these problems, scientists have done much work on investigating traditional Chinese medicine resources, exploring the metabolic pathway of bioactive ingredients, cultivating new varieties, and carrying out synthetic biology. These studies provided a theoretical basis for sustainable utilizationand future developmentof traditional Chinese medicine resources.

    Full Text Available For thousands of years, traditional medicine and remedies have been practed and used in the fight against disease in China. They have proved to be valuable and the distillate of vast historical experience based on field-tested human experiments, long-term observations and clinical trials. The Chinese people belive that traditional medicine is consistent with theirown culture. Endowed with a unique theoretical system and provided outstanding clinical results, traditional Chinese medicine continues to play an important role in helping the Chinese nation flourish. The recent study of traditional medicinal plants in Chine has given us confidence that what was recorded in ancient medical literature through empirical observations is indeed still coindicent with the concepts of modern chemistry, pharmacology and medicine. The task of revealing what is valid and efficacious should be retained, and what is mythic and invalid should be discarded in traditional Chinese medicine may require scientific research lasting for several generations. Therfore, multidisciplinary cooperation and international collaboration in this field would be essential. Systematic coordination of work in traditional medicine by word organizations, national governments, private foundations and individual scientists is a requisite as well.

    The industrialization chains and their products, which were formed from the process of the production of medicinal materials-prepared drug in pieces and deep processed product of Chinese material medica (CMM) resources, have generated large benefits of social and economic. However, The large of herb-medicine castoff of "non-medicinal parts" and "rejected materials" produced inevitably during the process of Chinese medicinal resources produce and process, and the residues, waste water and waste gas were produced during the manufactured and deep processed product of CMM. These lead to the waste of resources and environmental pollution. Our previous researches had proposed the "three utilization strategies" and "three types of resources models" of herb-medicine castoff according to the different physicochemical property of resources constitutes, resources potential and utility value of herb-medicine castoff. This article focus on the conversion efficiency of resources model and analysis the ways, technologies, practices, and application in herb-medicine cast off of the conversion efficiency of resources model based on the recycling economy theory of resources and thoughts of resources chemistry of CMM. These data may be promote and resolve the key problems limited the industrialization of Chinese material medica for long time and promote the realization of herb-medicine castoff resources utilization.

    Very many radioelement are used in medicine, either for diagnosis or as therapeutics. The development of medicine has entailed an increase in the number of application of radioactive isotopes. Firstly used in the form of simple inorganic molecules for diagnosis or as anticancer therapeutics, radioelements are now used for labelling organic molecules, allowing functional specific studies of any kind of nature. Their production is made difficult by their radio-active properties. Their pharmaceutical properties, determined by tests and controls, depend either from radiochemistry and from medicine. The author reminds, in this report, the methods for the preparation and analysis, and set out the medical application.

    This study aimed to investigate the antidiabetic, antilipidaemic and antioxidant activities of Citrus medica cv Diamante (Rutaceae) hydroalcoholic (CD) peel extract in Zucker diabetic fatty (ZDF) rats. The ability of CD to protect against oxidative stress was investigated by using different in vitro assays and in vivo by using the reactive oxygen metabolites-derived compounds (d-ROMs) test and the biological antioxidant potential test (BAP). Two different doses of CD extract (300 and 600 mg/kg/die) were administered at ZDF rats for 4 weeks. CD reduced cholesterol and triglycerides levels. A dose-dependent effect on body weight and serum glucose levels was observed. A decrease of d-ROMs and an increase of BAP were recorded by using the dose of 600 mg/kg. The extract inhibited lipid peroxidation (IC50 value of 0.23 mg/ml). These findings suggest as an efficient phytotherapeutic approach in combating hyperlipidaemic and hyperglycaemic disorders.

    Processing of Chinese Materia Medica (CMM) is a pharmaceutical technique to fulfill the different requirements of therapy, dispensing and making preparations according to traditional Chinese medicine theory. The aims of processing are to enhance the efficacy and/or reduce the toxicity of crude drugs. Those processed products are named as decoction pieces, which are used in clinics. Therefore, there is a close relationship between processing, safety, and efficacy of Chinese medicines. Some toxicity or side effects are caused by improper processing methods and some are due to improper combination of herbal mixtures. Standardization of processing methods for Chinese herbs is as important as authentication to maintain their quality and ensure their safe use. The objective of this paper is to review the literature covering the current situation and problems of CMM processing as well as recent progress in research in this area. A summary of the most urgent work needed is proposed.

    Near-infrared chemical imaging (NIR-CI) is an emerging technology that combines traditional near-infrared spectroscopy with chemical imaging. Therefore, NIR-CI can extract spectral information from pharmaceutical products and simultaneously visualize the spatial distribution of chemical components. The rapid and non-destructive features of NIR-CI make it an attractive process analytical technology (PAT) for identifying and monitoring critical control parameters during the pharmaceutical manufacturing process. This review mainly focuses on the pharmaceutical applications of NIR-CI in each unit operation during the manufacturing processes, from the Western solid dosage forms to the Chinese materia medica preparations. Finally, future applications of chemical imaging in the pharmaceutical industry are discussed.

    2016-04-01

    Historians of indigenous medicine in colonial India have looked more closely at the changes, reinventions and reformulations of institutions of Ayurveda and Unani than at the cognitive content of the drugs themselves. The few historians who have examined the changing content of indigenous medicines have conceptualised the creation of materia medica of Indian drugs through two tropes: one of circulation (of specific drugs) through epistemological and geographic boundaries and the second, of marginalisation of certain other drugs either through a lack of textual legitimacy or the lack of the newly discovered 'active principles' within each drug. While these approaches have been useful, there is a case to be made for understanding the creation of formularies of Indian drugs in 19th and 20th centuries through the prism of medical praxis in India.

    According to the process of the technical specification (TS) design for the fourth national survey of the Chinese materia medica resources (CMMR), we analyzed the assignment and objectives of the national survey and pointed out that the differences about CMMR management around China, the distribution of CMMR and their habitat, the economic and technological level, and even enthusiasm and initiative of the staff, etc. are the most difficult points for TS design. And we adopt the principle of combination of the mandatory and flexibility in TS design. We fixed the key points which would affect the quality of national survey first, then proposed the framework of TS which including 3 parts of organization and 11 parts of technique itself. The framework will serve and lead the TS preparation, which will not only provide an action standard to the national survey but will also have a profound influence to the popularization and application of the survey technology of CMMR.

    The definition of critical quality attributes of Chinese materia medica ( CMM) was put forward based on the top-level design concept. Nowadays, coupled with the development of rapid analytical science, rapid assessment of critical quality attributes of CMM was firstly carried out, which was the secondary discipline branch of CMM. Taking near infrared (NIR) spectroscopy as an example, which is a rapid analytical technology in pharmaceutical process over the past decade, systematic review is the chemometric parameters in NIR model evaluation. According to the characteristics of complexity of CMM and trace components analysis, a multi-source information fusion strategy of NIR model was developed for assessment of critical quality attributes of CMM. The strategy has provided guideline for NIR reliable analysis in critical quality attributes of CMM.

    The symbiosis between rhizobial bacteria and legume plants has served as a model for investigating the genetics of nitrogen fixation and the evolution of facultative mutualism. We used deep sequence coverage (>100×) to characterize genomic diversity at the nucleotide level among 12 Sinorhizobium medicae and 32 S. meliloti strains. Although these species are closely related and share host plants, based on the ratio of shared polymorphisms to fixed differences we found that horizontal gene transfer (HGT) between these species was confined almost exclusively to plasmid genes. Three multi-genic regions that show the strongest evidence of HGT harbor genes directly involved in establishing or maintaining the mutualism with host plants. In both species, nucleotide diversity is 1.5-2.5 times greater on the plasmids than chromosomes. Interestingly, nucleotide diversity in S. meliloti but not S. medicae is highly structured along the chromosome - with mean diversity (θ(π)) on one half of the chromosome five times greater than mean diversity on the other half. Based on the ratio of plasmid to chromosome diversity, this appears to be due to severely reduced diversity on the chromosome half with less diversity, which is consistent with extensive hitchhiking along with a selective sweep. Frequency-spectrum based tests identified 82 genes with a signature of adaptive evolution in one species or another but none of the genes were identified in both species. Based upon available functional information, several genes identified as targets of selection are likely to alter the symbiosis with the host plant, making them attractive targets for further functional characterization.

    Aucklandia lappa Decne was first recorded in the Sheng nong ben cao jing (Shennong's Classic of Materia Medica). Through the textual research of herbal literature, it was found that the costus root in the Sheng nong ben cao jing perhaps was not the plant of Aucklandia lappa Decne of Compositae, but the eaglewood or Lignum Aquilasria Resinatum based on the comprehensive judgment of shape, taste, nature, and function etc. In the Sheng nong ben cao jing, it only includes costus root without the title of eaglewood, and Tao Hongjing recorded both herbs together in his Ming yi bie lu (Supplementary Records of Celebrated Physicians), which became a foreshadow of misunderstanding of the later generations. Beginning from the Tang ben cao (Materia Medica of the Tang Dynasty), the costus root was considered as the plant of Auckiandia lappa Decne from the Compostae with its profound influence until now.

MÉTODO: Foram avaliados dois grupos de pacientes: um com diagnóstico de PC e outro sem doença do sistema nervoso central (SNC e periférico. Foram registrados valores de EEG-BIS na enfermaria na véspera da operação e no dia da operação, 40 minutos depois da administração de 0,6 mg.kg-1 de midazolam via oral. Foram excluídos pacientes com história de reação paradoxal ao midazolam e pacientes do grupo-controle que estivessem em uso de outra medicação. RESULTADOS: Foram estudados 77 pacientes de ambos os sexos, entre 4 e 18 anos de idade. Não houve diferença entre os valores de EEG-BIS basal entre os grupos estudados. Após o uso do midazolam houve diminuição dos valores do EEG-BIS nos dois grupos estudados, com diferença estatística significativa em cada grupo. Na comparação entre grupos não houve diferença estatística. CONCLUSÕES: O midazolam administrado como medicação pré-anestésica na dose de 0,6 mg.kg-1 diminui os valores basais do EEG-BIS sem caracterizar hipnose e sem diferença estatística nos grupos estudados.JUSTIFICATIVA Y OBJETIVOS: El midazolam es un derivado benzodiazepínico con acción hipnótica y muy utilizado como medicación preanestésica en anestesia pediátrica. Los niños con parálisis cerebral (PC también se benefician del uso del midazolam, pero sus efectos todavía se desconocen sobre ese

    We report an eco-friendly method for the synthesis of copper nanoparticles (CuNPs) using Citron juice (Citrus medica Linn.), which is nontoxic and cheap. The biogenic copper nanoparticles were characterized by UV-Vis spectrophotometer showing a typical resonance (SPR) at about 631 nm which is specific for CuNPs. Nanoparticles tracking analysis by NanoSight-LM20 showed the particles in the range of 10-60 nm with the concentration of 2.18 × 10(8) particles per ml. X-ray diffraction revealed the FCC nature of nanoparticles with an average size of 20 nm. The antimicrobial activity of CuNPs was determined by Kirby-Bauer disk diffusion method against some selected species of bacteria and plant pathogenic fungi. It was reported that the synthesized CuNPs demonstrated a significant inhibitory activity against Escherichia coli followed by Klebsiella pneumoniae, Pseudomonas aeruginosa, Propionibacterium acnes and Salmonella typhi. Among the plant pathogenic fungi tested, Fusarium culmorum was found to be most sensitive followed by F. oxysporum and F. graminearum. The novelty of this work is that for the first time citron juice was used for the synthesis of CuNPs.

    Ensifer (Sinorhizobium) medicae is an effective nitrogen fixing microsymbiont of a diverse range of annual Medicago (medic) species. Strain WSM419 is an aerobic, motile, non-spore forming, Gram-negative rod isolated from a M. murex root nodule collected in Sardinia, Italy in 1981. WSM419 was manufactured commercially in Australia as an inoculant for annual medics during 1985 to 1993 due to its nitrogen fixation, saprophytic competence and acid tolerance properties. Here we describe the basic features of this organism, together with the complete genome sequence, and annotation. This is the first report of a complete genome sequence for a microsymbiont of the group of annual medic species adapted to acid soils. We reveal that its genome size is 6,817,576 bp encoding 6,518 protein-coding genes and 81 RNA only encoding genes. The genome contains a chromosome of size 3,781,904 bp and 3 plasmids of size 1,570,951 bp, 1,245,408 bp and 219,313 bp. The smallest plasmid is a feature unique to this medic microsymbiont.

    The present paper firstly reviewed the research progress and main methods of NIR spectral assignment coupled with our research results. Principal component analysis was focused on characteristic signal extraction to reflect spectral differences. Partial least squares method was concerned with variable selection to discover characteristic absorption band. Two-dimensional correlation spectroscopy was mainly adopted for spectral assignment. Autocorrelation peaks were obtained from spectral changes, which were disturbed by external factors, such as concentration, temperature and pressure. Density functional theory was used to calculate energy from substance structure to establish the relationship between molecular energy and spectra change. Based on the above reviewed method, taking a NIR spectral assignment of chlorogenic acid as example, a reliable spectral assignment for critical quality attributes of Chinese materia medica (CMM) was established using deuterium technology and spectral variable selection. The result demonstrated the assignment consistency according to spectral features of different concentrations of chlorogenic acid and variable selection region of online NIR model in extract process. Although spectral assignment was initial using an active pharmaceutical ingredient, it is meaningful to look forward to the futurity of the complex components in CMM. Therefore, it provided methodology for NIR spectral assignment of critical quality attributes in CMM.

    Objective To investigate the effects of candesartan, an angiotensiou Ⅱ type Ⅰ receptor antagonist, in improvement of insulin resistance (IR) induced by high-fat diet and the possible mechanism thereof. Methods 45 male Wistar rats were randomly divided into 3 groups: normal chow group (NC, n= 15) fed with normal diet, high fat diet group (HF, n=15) fed with high fat diet, and high-fat diet with daily candesartsn treatment group (HF+C, n=15) fed with high fat diet and given orally with candesartan 8 mg/kg per day. Body weight was measured regularly. Four weeks later, oral glucose tolerance test (OGTT) and euglycemic-hyperinsulinemic clamp technique were performed to estimate the insulin sensitivity. After 12 h fasting blood samples were collected from the abdominal aorta to test the contents of blood glucose, and serum triglyceride (TG), total cholesterol (TC), LDL, HDL, and free fatty acid (FFA). Radioimmunoassay was used to detect the serum insulin. Viscera were taken out. Immunohistochemistry was used to examine the expression of peroxisome proliferation activated receptor (PPAR)-γ in hepatic and adipose tissues. Results The body weight 16 weeks later of the HF group was significantly higher than that of the HF + C group (P 0.05). The glucose levels 2 h after OGTT in the HF + C group was (6.3±0.5) mmol/L, significantly lower than that of the HF group [(7.3±1.2) mmol/L, P0.05),但HF+c组葡萄糖负荷后2 h血糖明显低于HF组[(6.3±0.5)mmol/L vs(7.3±1.2)mmol/L,P<0.01].钳夹结果显示HF+C组葡萄糖输入率明显高于HF组[(22±5)mmoL/L vs(14±4)mmol/L,P<0.01].HF+C组肝脏和脂肪PPAγ蛋白表达水平明显高于HF组.结论 坎地沙坦可明显改善高脂饮食大鼠的胰岛素抵抗,肝脏和脂肪组织PPARγ的高表达.

    Full Text Available Novas tecnologias diagnósticas e terapêuticas são cada vez mais utilizadas, melhorando a qualidade assistencial e aumentando a expectativa de vida; entretanto, a atenção à saúde vem se tornando mais cara e complexa. Os eventos adversos relacionados à assistência, especialmente os erros, são cada vez mais conhecidos, discutidos e julgados em tribunais. Os profissionais de saúde, devido à sua formação, não estão preparados para lidar com os erros, pois estes estão associados à vergonha, ao medo e às punições. A abordagem dos erros no sistema de saúde é, geralmente, feita de forma individualista, considerando os erros como atos inseguros cometidos por pessoas desatentas, desmotivadas e com treinamento deficiente. Quando o erro ocorre, a tendência é escondê-lo, perdendo-se oportunidade importante de aprendizado. Existe outro modo de lidar com erros, a visão sistêmica, que na sua aplicação apresenta bons resultados em setores como aviação, anestesia e sistemas de distribuição de medicamentos por dose unitária. Os sistemas possuem graus variados de segurança e devem levar em conta, na sua construção e funcionamento, as limitações humanas. Em relação ao uso dos medicamentos, uma mudança de paradigma é necessária, pois não basta um medicamento ter qualidade garantida, mas o seu processo de utilização também deve ser seguro. Os erros de medicação, que são por definição evitáveis, são atualmente um sério problema de saúde pública, levando a perdas de vidas e desperdício importante de recursos financeiros. A abordagem sistêmica dos erros de medicação poderá revelar as falhas do processo, sendo possível implementar melhorias, diminuindo, assim, a ocorrência desses eventos.New diagnostic and therapeutic technologies are used with growing frequency, improving the quality of medical assistance and increasing life expectancy.

    is evaluated when this information has not been told to the surgeon. If this information had been known by the surgeon what attitude has been taken by the attending surgeon. METHOD: Four hundred and sixteen patients from the Hospital Universitário de Taubaté (HUT in Regional Hospital de Taubaté (HRT and in private plastic surgery clinic were studied on preoperative basis. A thorough search with quantitative and qualitative variables of nonprescription drugs (aspirin and E vitamin and herbal medicines (Ginkgo biloba, Garlic and Ginger was undertaken. Data were obtained though a questionnaire related to the use of these medications from one year and 10 days before surgery. It was computed if the surgeon has been informed of its use and what attitude had been taken about withdrawing or nor this medication. RESULTS: Most of the patients (58.89% have not used any of these drugs, 39% have used them the last year and 13.83% have used them in the last 10 days. Aspirin was the medicine most used and Ginkgo biloba was the preferred among the herbal medicines. The consumption of these drugs has been informed in 73.69% of the patients that had used them. CONCLUSION: In the studied population it is high the percentage of the use of drugs that interferes in the blood coagulation. The most frequent medications are:Aspirin, E vitamin and Ginkgo biloba. Most of the researched patients did not inform the surgeon about its use.It should be emphasized the need of questioning the use of these drugs before surgery, with the objective of reducing possible hemorrhage complications per and postoperatively, becauseof its medical complications and possible legal implications.

    All previous literatures about Chinese herbal medicines show distinctive traditional Chinese medicine (TCM) flavors. Compendium of Materia Medica is an influential book in TCM history. The TCM flavor theory and flavor standardization principle in this book has important significance for modern TCM flavor standardization. Compendium of Materia Medica pays attention to the flavor theory, explain the relations between the flavor of medicine and its therapeutic effects by means of Neo-Confucianism of the Song and Ming Dynasties. However,the book has not reflected and further developed the systemic theory, which originated in the Jin and Yuan dynasty. In Compendium of Materia Medica , flavor are standardized just by tasting medicines, instead of deducing flavors. Therefore, medicine tasting should be adopted as the major method to standardize the flavor of medicine.

    This paper aims to summarize the achievements during the implementation process of good agricultural practice (GAP) in Chinese Materia Medica (CMM), and on basis of analyzing the existing problems of GAP, to propose further implementation of GAP in TCM growing. Since the launch of GAP in CMM growing ten years ago, it has acquired great achievements, including: (1) The promulgation of a series of measures for the administration of the GAP approval in the CMM growing; (2) The expanded planting area of CMM; (3) The increased awareness of standardized CMM growing among farmers and enterprises; (4) The establishment of GAP implementation bases for CMM growing; (5) The improvement of theory and methodology for CMM growing; (6) The development of a large group of experts and scholars in GAP approval for CMM production. The problems existing in the production include: (1) A deep understanding of GAP and its certification is still needed; (2) The distribution of the certification base is not reasonable; (3) The geo-economics effect and the backward farming practices are thought to be the bottlenecks in the standardization of CMM growing and the scale production of CMM; (4) Low comparative effectiveness limits the development of the GAP; (5) The base of breeding improved variety is blank; (6) The immature of the cultivation technique lead to the risk of production process; (7) The degradation of soil microbial and the continuous cropping obstacle restrict the sustainable development of the GAP base. To further promote the health and orderly GAP in the CMM growing, the authors propose: (1) To change the mode of production; (2) To establish a sound standard system so as to ensure quality products for fair prices; (3) To fully consider the geo-economic culture and vigorously promote the definite cultivating of traditional Chinese medicinal materials; (4) To strengthen the transformation and generalization of basic researches and achievements, in order to provide technical

  6. The Doctrine of Signatures, Materia Medica of Orchids, and the Contributions of Doctor - Orchidologists.

    2012-12-01

    The heritage of medicine is written in many forms. One repository is to be found in the history of orchids, the world's largest family of flowering plants. Orchids were so named by Theophrastus (c.372-288 BC) who recorded their medicinal use as an aphrodisiac and the promoter of virility, in the context of the Doctrine of Signatures. Such use endured for millennia, and was recorded both by Paracelsus (1493-1551) and Linnaeus (1707-1778). The history of orchidology and medicine are entwined in four domains: (a) orchids and their historical materia medica, within the paradigm of the Doctrine of Signatures; (b) the enduring and extensive contemporary medicinal and culinary use of orchids such as Vanilla and salep extracts of Orchis; (c) the scientific contributions of doctors as orchidologists; and (d) the heritage of more than a hundred doctors' names in the scientific etymology of the Orchidaceae family. Prominent orchidologists have included the Scottish doctor-soldier and botanist, Robert Brown (1773-1858); the Director of the State Herbarium at Leyden and the Rijks Museum, Carl Ludwig Blume (1796-1862); and Dr William Sterling MD (1888-1967). Among the more than 1250 genus names (and 33,000 species) of orchids are the names of more than a hundred doctors, their lives and works perpetuated in the scientific etymology of this family of exotic, beautiful, flamboyant, intriguing and often expensive flowers. Generic names record the lives and works of such as Aristotle (384-322BC) in Aristotelia Loureiro 1790; Cadet de Gassicourt (1769-1821) in Cadetia Gaudichaud 1826; Sir Joseph Dalton Hooker (1817-1911) in Sirhookera O. Kuntze 1891; and Dr Theodore Daniel Vrydag Zynen (fl. 1820-1850) in Vrydagzynea Blume 1858. One of the principal horticultural genera of orchids, Brassavola, records the life and work of the Ferrara and Padua physician and botanist, Antonio Musa Brassavola (1500-1555).

    Group II introns are self-splicing catalytic RNAs that act as mobile retroelements. In bacteria, they are thought to be tolerated to some extent because they self-splice and home preferentially to sites outside of functional genes, generally within intergenic regions or in other mobile genetic elements, by mechanisms including the divergence of DNA target specificity to prevent target site saturation. RmInt1 is a mobile group II intron that is widespread in natural populations of Sinorhizobium meliloti and was first described in the GR4 strain. Like other bacterial group II introns, RmInt1 tends to evolve toward an inactive form by fragmentation, with loss of the 3' terminus. We identified genomic evidence of a fragmented intron closely related to RmInt1 buried in the genome of the extant S. meliloti/S. medicae species. By studying this intron, we obtained evidence for the occurrence of intron insertion before the divergence of ancient rhizobial species. This fragmented group II intron has thus existed for a long time and has provided sequence variation, on which selection can act, contributing to diverse genetic rearrangements, and to generate pan-genome divergence after strain differentiation. The data presented here suggest that fragmented group II introns within intergenic regions closed to functionally important neighboring genes may have been microevolutionary forces driving adaptive evolution of these rhizobial species.

    Ensifer medicae Di28 is an aerobic, motile, Gram-negative, non-spore-forming rod that can exist as a soil saprophyte or as a legume microsymbiont of Medicago spp. Di28 was isolated in 1998 from a nodule recovered from the roots of M. polymorpha growing in the south east of Sardinia (Italy). Di28 is an effective microsymbiont of the annual forage legumes M. polymorpha and M. murex and is capable of establishing a partially effective symbiotic association with the perennial M. sativa. Here we describe the features of E. medicae Di28, together with genome sequence information and its annotation. The 6,553,624 bp standard draft genome is arranged into 104 scaffolds of 104 contigs containing 6,394 protein-coding genes and 75 RNA-only encoding genes. This rhizobial genome is one of 100 sequenced as part of the DOE Joint Genome Institute 2010 Genomic Encyclopedia for Bacteria and Archaea-Root Nodule Bacteria (GEBA-RNB) project.

    Ensifer medicae strain WSM1115 forms effective nitrogen fixing symbioses with a range of annual Medicago species and is used in commercial inoculants in Australia. WSM1115 is an aerobic, motile, Gram-negative, non-spore-forming rod. It was isolated from a nodule recovered from the root of burr medic (Medicago polymorpha) collected on the Greek Island of Samothraki. WSM1115 has a broad host range for nodulation and N2 fixation capacity within the genus Medicago, although this does not extend to all medic species. WSM1115 is considered saprophytically competent in moderately acid soils (pH(CaCl2) 5.0), but it has failed to persist at field sites where soil salinity exceeded 10 ECe (dS/m). Here we describe the features of E. medicae strain WSM1115, together with genome sequence information and its annotation. The 6,861,065 bp high-quality-draft genome is arranged into 7 scaffolds of 28 contigs, contains 6,789 protein-coding genes and 83 RNA-only encoding genes, and is one of 100 rhizobial genomes sequenced as part of the DOE Joint Genome Institute 2010 Genomic Encyclopedia for Bacteria and Archaea-Root Nodule Bacteria (GEBA-RNB) project.

    Full Text Available Con la pronuncia n. 13328 del 30 giugno 2015, la Corte di Cassazione si è occupata della rilevanza che nei giudizi di responsabilità civile medica deve attribuirsi al concetto di «complicanza», espressione con la quale – secondo la Suprema Corte – «la medicina clinica e la medicina legale designano solitamente un evento dannoso, insorto nel corso dell’iter terapeutico, che pur essendo astrattamente prevedibile, non sarebbe evitabile» e che, come tale, esclude la sussistenza della responsabilità in discorso. Affermando principi che, come meglio vedremo, sembrano porsi in distonia con il consolidato orientamento giurisprudenziale in materia, la pronuncia in esame ha sostenuto che «tale concetto è inutile nel campo giuridico.

    The activity of most deoxyribonuclease enzymes can be monitored by measuring the change in absorbance at 260 nm which accompanies the breakdown of the double-stranded structure of native DNA. An automated method for determining deoxyribonuclease activity, based on such an absorbance change, which can overcome problems of inhibition arising from the presence of inorganic cations, is described. Variations in inorganic cation concentration is a particular problem when measuring the activity of chromatographic fractions eluted via a salt gradient. A comparison is made between the automated and a manual method for the assay of deoxyribonuclease active constituents, of the medicament 'Varidase', eluted from a Cellex-D (Bio-Rad Laboratories Ltd) anionic exchange resin using a 0.05-1.0 M sodium chloride gradient.

    Yuzhu (Polygonati Odorati Rhizoma), Kangdingyuzhu (Polygonati Prattii Rhizoma), and zhugenqiyuzhu (Disporopsis Fuscopictae Rhizoma) are of the same family, but of different genera. They have all often used in Chinese Materia Medica (CMM) as Polygonati Odorati Rhizoma in China market. Three species of CMM are confused. For better application, we need to identify these plants accurately. This study use pharmacognosy technique and GC-MS analysis, three species of CMM were authenticated. In macroscopic characteristics, the fruit of Polygonati Odorati Rhizoma is blue-black, while the other two are maroon and dark purple orderly. Nodes of Polygonati Odorati Rhizoma are upward and light uplift, about 1 cm spacing, while the other are not. As for microscopic characteristics, the cortex of Polygonati Odorati Rhizoma only occupies about 1/5 of the radius of the transverse section with inconspicuous endodermis, which is much smaller than others. The type of vascular bundles of Polygonati Odorati Rhizoma is closed collateral, but the other is amphivasal. Raphides of calcium oxalate are scattered, but Raphides of the other two are like brooms and neat rows. GC-MS analysis of essential oil could provide different characteristics to distinguish three species. Twenty-three compounds were identified from essential oil of Polygonati Odorati Rhizoma and the main components were n-hexadecanoic acid (49.45%), while n-hexadecanoic acid of the other two are 23.92% and 9.45%. The content of n-hexadecanoic is strongly different. This research was aimed to establish a method by pharmacognosy and GC-MS analysis to identify three CMM and for providing scientifical data to ensure accuracy of origin of three species.

    Full Text Available John Locke’s essay Ars medica of 1669, is presented, analyzed and translated into Spanish. This essay shows the medical problems that prompted Locke´s philosophy and provides essential clues to understanding the motives, aims and characteristics of the empiricist`s theory of knowledge. Ideas originated in medicine that profoundly influenced subsequent Locke`s works were: 1 Trust in the perfectibility of science and elucidation of the role that philosophical thinking could play. 2 Rejection of knowledge deduced from principles, hypotheses or maxims. 3 Reliance on a «plain historical method» for the production of knowledge, which tried to register facts descriptively, while abandoning the study of ultimate causes. 4 Use of a three-part classification of the sciences that enthrones semiotics, medical science par excellence, and defines it as a mere knowledge of the signs of things, that is not intended to discern either essences or substances. Locke, in his epistemology, applies to all scientific knowledge the medical theory of the signs of illnesses. He envisions all possible science as a mere descriptive knowledge of signs; and thinks that knowledge is probabilistic, analogous and pragmatic.Se presenta, analiza y traduce por primera vez al castellano, el ensayo Ars Medica escrito por John Locke en 1669. Este ensayo muestra los problemas médicos que dieron origen al conjunto de la filosofía de Locke; y ofrece claves esenciales para comprender los motivos, las metas y los rasgos de la teoría del conocimiento empirista. Ideas originariamente médicas que tuvieron una repercusión directa en la obra posterior de Locke fueron: 1 Confianza en la perfectibilidad de la ciencia y elucidación del papel que la reflexión filosófica podía desempeñar en ello. 2 Rechazo del conocimiento deducido de principios, hipótesis o máximas. 3 El método «histórico simple» para edificar el conocimiento; que intentaba registrar los hechos descriptivamente

    The acupoint is one of the basic elements of the acupuncture prescription. Just as thinking over different properties of every Chinese materia medica in a prescription, we should also sufficiently consider the characteristics of each acupoint in a prescription of acupuncture or moxibustion. Chinese materia medica have their own action-tendencies of lifting, lowering, floating and sinking, properties of cold, hot, warm and cool, five flavors of sour, bitter, sweet, acrid and salty, target-meridian distribution, different toxicity and actions, etc. What are the properties of acupoints? The authors of the present paper summarize them by simulating the characters of Chinese materia medica. It is found that acupoints also have functions in regulating lifting, lowering, floating and sinking of Qi, inducing cold and heat effects, producing different needling sensations; and pertain to different meridians (meridian distribution). And acupoint stimulation may produce adverse effects under certain specific conditions, etc. Full understanding of the properties of acupoints is definitely helpful in improving clinical therapeutic effects and shortening therapeutic courses by reasonably selecting and combining related acupoints.

    The quality of Chinese materia medica (CMM) is affected by every process in CMM manufacturing. According to multi-unit complex features in the production of CMM, on-line near infrared spectroscopy (NIR) is used as an evaluating technology with its rapid, non-destructive and non-pollution etc. advantages. With the research in institutions, the on-line NIR applied in process analysis and control of CMM was described systematically, and the on-line NIR platform building was used as an example to clarify the feasibility of on-line NIR technology in CMM manufacturing process. Then, from the point of application by pharmaceutical companies, the current on-line NIR research on CMM and its production in pharmaceutical companies was relatively comprehensively summarized. Meanwhile, the types of CMM productions were classified in accordance with two formulations (liquid and solid dosage formulations). The different production processes (extraction, concentration and alcohol precipitation, etc. ) were used as liquid formulation diacritical points; the different types (tablets, capsules and plasters, etc.) were used as solid dosage formulation diacritical points, and the reliability of on-line NIR used in the whole process in CMM production was proved in according to the summary of literatures in recent 10 years, which could support the modernization of CMM production.

Nevertheless, few studies utilize the proper methodology to carry out that evaluation with anaerobes. In this study, the steps of a broth dilution method, carried out in microplates (microdilution and tubes (macrodilution, to test the effect of traditional intracanal medicaments on anaerobic bacteria are described. The results are presented as values of minimal inhibitory and bactericidal concentrations (MIC and MBC. Standardized inocula of the anaerobic bacteria Prevotella nigrescens (ATCC 33563, Fusobacterium nucleatum (ATCC 25586 and Clostridium perfringens (ATCC 13124, in reinforced Clostridium medium (RCM and supplemented Brucella broth, were submitted to different concentrations of calcium hydroxide, chlorhexidine digluconate, camphorated paramonochlorophenol and formocresol solutions. The drugs were diluted in the same culture broths, in microplates and tubes, and were then incubated in anaerobiosis jars at 37ºC for 48 or 96 hours. The determination of MICs was carried out through visual and spectrophotometric readings, and the determination of MBCs, through the plating of aliquots on RCM-blood agar. For that kind of study, the macromethod with spectrophotometric reading should be the natural choice. MICs and MBCs obtained with the macromethod were compatible with the known clinical performance of the studied medications, and the values varied according to the bacteria and culture media employed.

    Full Text Available Abstract Background The reduction of blood pressure alone does not eliminate the increased risk of arterial hypertension. Whilst concomitant metabolic risk factors have been shown to be responsible, the available pharmacotherapy has differential effects on these metabolic risk factors. For example, diuretics and betablockers worsen glucose metabolism, hence the starting point of the current subanalysis of the CHILI (Candesartan in patients with HIgher cardiovascuLar rIsk study was the assumption that an angiotensin receptor blocker may counterbalance the metabolic effects of a low dose diuretic in patients with several metabolic risk factors. Methods The present study was performed as a non-interventional observational study in Germany. Patients with previously uncontrolled hypertension with at least one further risk factor in which physicians deemed a treatment with 16 mg Candesartan/12.5 mg HCTZ to be necessary were included. The risk factors were calculated in patient subgroups with diabetes, the metabolic syndrome (MetSyn and neither condition (control. The risk of cardiovascular mortality within the next 10 years was calculated using the SCORE algorithm of the ESC. Results Between August 2006 and February 2007 a total of 3,787 patients were included into the non-interventional trial. Patients were 62.2 ± 11.3 years old, 48.1% were female, 97.5% had at least one additional risk factor. Blood pressure was reduced by -27.2/-13.4 mmHg with only minor non significant variations between patient groups. Waist circumference was reduced (P Conclusion The present study demonstrates that a 16 mg candesartan/12.5 mg HCTZ based treatment results in a pronounced blood pressure reduction and was associated with a favourable change in metabolic risk factors such as HDL cholesterol, triglycerides and blood glucose. These data indicate that metabolic effects observed in clinical trials like ALPINE, SCOPE or CHARM can also be observed in an unselected

    Toxic and Potent Chinese Materia Medica (T/PCMM) is a special and very important category of Chinese medicines. They have long been used in traditional medical practice and are being used more and more widely throughout the world in recent years. As there may be many fatal toxic effects caused by misusing or confusion of T/PCMM, their quality and safety control arouse increasing attention internationally. Researches on the accurate identification to ensure the safe use of T/PCMM are acquired; however, there are few reports on authentication. We are carrying out a series of studies on 31 T/PCMM originating from plants, animals, minerals, and secreta. In our previous studies, we proved that modern microscopic authentication is a simple, fast, effective, low cost, and less toxic method for identifying animal, seed, and flower T/PCMM. In the present study, we focused on the authentication of four kinds of mineral arsenicals, including orpiment (mainly containing As₂S₃), realgar (mainly containing As₄S₄), arsenolite, and arsenic trioxide (mainly containing As₂O₃). We examined the macroscopic and microscopic characteristics of the above minerals and found that they all can be easily identified and authenticated by using light microscopy coupled with polarized microscopy. Moreover, the authentication results for arsenolite and arsenic trioxide are confirmed by ICP-MS analysis. We are sure that the morphological and microscopic characteristics indicated here are indispensable to establishing standards for these four mineral T/PCMMs.

    The article analyzes a 1790 manuscript copy of Materia medica misionera, a book written in 1710 by a Jesuit, Pedro Montenegro. Alongside knowledge of a magical or religious nature, and exotic ingredients for the recipes, this work also contains the unmistakable presence of Hippocratic and Galenic conceptions and a growing empiricism, characteristic of the scientific transformations seen in the eighteenth century. The analysis of this work also prompts reflections about the diffusion, circulation and production of pharmacological and medical knowledge in the first half of the eighteenth century within the missions and colleges installed in the area that was the Jesuit Province of Paraguay, southern America.

    Full Text Available The article describes a forgotten work of Daniel Naborowski – “De temperamentis disputatio medica” (1593. Naborowski was a poet who lived at the turn of the 17th century and the work considered here is the result of his medical studies in Switzerland. The article addresses the poet’s scholarly interests, but first and foremost, it focuses on the subject of the research – the theory of temperaments. With ancient lineage and extremely popular in the sixteenth century, the theory was most frequently presented in the contexts of physiognomy, astrology and the lesions that were conditioned by the theory, yet in Naborowski’s work, it gained a new, solely theoretical perspec-tive. It was also concerned with the meticulous consideration of the systematics of temperaments (e.g. their differentiation – one was moderate and eight were merged, as well as their detailed division. The style of these considerations is characteristic for medical works of that period, and they constitute an interesting example of how practical issues in 16th and 17th century medicine were systematized. Furthermore, Naborowski’s considerations are a vivid example of permeable nature of disciplines – philosophy and medicine, and medicine with the broadly understood field of the humanities.

    Knowledge Discovery in Databases is gaining attention and raising new hopes for traditional Chinese medicine (TCM) researchers. It is a useful tool in understanding and deciphering TCM theories. Aiming for a better understanding of Chinese herbal property theory (CHPT), this paper performed an improved association rule learning to analyze semistructured text in the book entitled Shennong's Classic of Materia Medica. The text was firstly annotated and transformed to well-structured multidimensional data. Subsequently, an Apriori algorithm was employed for producing association rules after the sensitivity analysis of parameters. From the confirmed 120 resulting rules that described the intrinsic relationships between herbal property (qi, flavor and their combinations) and herbal efficacy, two novel fundamental principles underlying CHPT were acquired and further elucidated: (1) the many-to-one mapping of herbal efficacy to herbal property; (2) the nonrandom overlap between the related efficacy of qi and flavor. This work provided an innovative knowledge about CHPT, which would be helpful for its modern research.

    The chemical composition of the essential oil of Citrus medica L. cv. Diamante peel obtained by hydrodistillation, cold-pressing and supercritical carbon dioxide extraction techniques was determined by GC/MS analysis. Forty-six components were fully characterised. Limonene and γ-terpinene were the major components of the oils obtained by hydrodistillation (HD) and cold-pressing (CP), while citropten was the major constituent in the oil obtained by supercritical carbon dioxide extraction (SFE). Acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) inhibitory activities were evaluated. The essential oil obtained by hydrodistillation exerted the highest inhibitory activity against BChE (IC₅₀ value of 154.6 µg mL⁻¹) and AChE (IC₅₀ value of 171.3 µg mL⁻¹. Interestingly, the oil obtained by cold-pressing exhibited a selective inhibitory activity against AChE. The essential oils have also been evaluated for the inhibition of NO production in LPS induced RAW 264.7 macrophages. The oil obtained by hydrodistillation exerted a significant inhibition of NO production with an IC₅₀ value of 17 µg mL⁻¹ (IC₅₀ of positive control 53 µg mL⁻¹).

Swingle.The results indicate that the secretory cavity of the variety seemed to originate from an epidermal cell and a subepidermal cell. These two cells underwent successive divisions, resulting in the formation of two parts: (i) a conical cap; and (ii) a globular gland. The formation of the lumen was schizolysigenous. Regular changes in the size of vacuoles and the accumulation of essential oil were revealed during the process of secretory cavity development. In addition, when fruits were a light yellow or golden color, the structure of secretory cavities was well developed and the content of essential oil in a single fruit reached a maximum. It would be most appropriate to collect the fruit as a medicinal material at this time.

    Full Text Available The retention of pulpally involved deciduous tooth in a healthy state until the time of normal exfoliation remains to be one of the challenges for Pedodontists. A scientific noise has been generated about several materials some of which have been popular pulpotomy medicaments. Concerns have been raised about the toxicity and potential carcinogenicity of these materials, and alternatives have been proposed to maintain the partial pulp vitality, however to date no material has been accepted as an ideal pulpotomy agent. Mineral trioxide aggregate (MTA is a biocompatible material which provides a biological seal. MTA has been proposed as a potential medicament for various pulpal procedures like pulp capping with reversible pulpitis, apexification, repair of root perforations, etc. Hence the present study was done to evaluate the efficacy of MTA as a pulpotomy medicament. A clinical and radiographic evaluation was done on children where MTA was used as pulpotomy medicament in primary molars for a period of 6 months and it was found to be a successful material.

    Full Text Available Vital pulp therapy (VPT is a biologic and conservative treatment modality to preserve the vitality and function of the coronal or remaining radicular pulp tissue in vital permanent teeth. A search was conducted via the Cochrane database, PubMed, MEDLINE, and Ovid for any articles with the criteria for "pulp-capping," or "pulp-capping materials" and "VPT outcomes" from 1978 to mid 2014. All articles were evaluated and the valid papers were selected. The outcomes of various VPT techniques, including indirect pulp treatment, direct pulp treatment, partial pulpotomy, and complete pulpotomy in vital permanent teeth were extracted. Although various studies have different research approach, most studies noted a favorable treatment outcome. Mineral trioxide aggregate (MTA appears to be more effective than calcium hydroxide (Ca(OH 2 for maintaining long-term pulp vitality after indirect and direct pulp-capping. However, it seems that the success rate for partial pulpotomy and pulpotomy with Ca(OH 2 is similar to MTA.

    Vital pulp therapy (VPT) is a biologic and conservative treatment modality to preserve the vitality and function of the coronal or remaining radicular pulp tissue in vital permanent teeth. A search was conducted via the Cochrane database, PubMed, MEDLINE, and Ovid for any articles with the criteria for “pulp-capping,” or “pulp-capping materials” and “VPT outcomes” from 1978 to mid 2014. All articles were evaluated and the valid papers were selected. The outcomes of various VPT techniques, including indirect pulp treatment, direct pulp treatment, partial pulpotomy, and complete pulpotomy in vital permanent teeth were extracted. Although various studies have different research approach, most studies noted a favorable treatment outcome. Mineral trioxide aggregate (MTA) appears to be more effective than calcium hydroxide (Ca(OH)2) for maintaining long-term pulp vitality after indirect and direct pulp-capping. However, it seems that the success rate for partial pulpotomy and pulpotomy with Ca(OH)2 is similar to MTA. PMID:26604953

    The experimental pharmacological research on Ma - Huang and Tang - Kuei (Danggui) by Chen Kokuei and his colleagues in 1923,is the proem of scientific research on Chinese materia medica (CMM) in China.In the 1930' s,a number of scientific research institutions were established in China,such as,the Institute of Physiology,National Academy of Peiping and the pharmaceutical laboratory of the experimental hygiene station,National Economic Council.Experts undertook extensive research on CMM.They injected the rough extractum or purified active constituent in laboratory animals to observe the characteristics of drugs and published a series of treatises.They made experimental objectives and selected experimental herbs according to TCM theory.Their inheritance and innovation in the research demonstrated better rationality than simultaneous overseas scholars to whom they were therefore superior.%1923年陈克恢等对于麻黄、当归的实验药理研究是我国近代中药药理研究的开端.20世纪30年代,国内相继建立起一批科研机构,如国立北平研究院生理学研究所、全国经济委员会卫生实验处药物研究室等,广泛地开展了中药的药理研究,将中药粗制浸膏或精制有效成分注入实验动物体内,观察药物作用的特点,陆续发表了多篇研究论文.在研究过程中,他们根据传统中医药知识确定实验目标,借鉴传统知识选用实验药材,在探索中继承和创新,表现出比同时期国外学者的自然药物实验研究更强的合理性和优越性.

    Intracellular triacylglycerol (TG) content of liver and skeletal muscle contributes to insulin resistance, and a significant correlation exists between TG content and the development of insulin resistance. Because acetyl-CoA carboxylase (ACC) is the rate-limiting enzyme for liver fatty acid biosynthesis and a key regulator of muscle fatty acid oxidation, we examined whether ACC plays a role in the accumulation of intracellular TG. We also determined the potential role of 5'-AMP-activated protein kinase (AMPK) in this process, since it can phosphorylate and inhibit ACC activity in both liver and muscle. TG content, ACC, and AMPK were examined in the liver and skeletal muscle of insulin-resistant JCR:LA-cp rats during the time frame when insulin resistance develops. At 12 weeks of age, there was a threefold elevation in liver TG content and a sevenfold elevation in skeletal muscle TG content. Hepatic ACC activity was significantly elevated in 12-week-old JCR:LA-cp rats compared with lean age-matched controls (8.75 +/- 0.53 vs. 3.30 +/- 0.18 nmol. min(-1). mg(-1), respectively), even though AMPK activity was also increased. The observed increase in hepatic ACC activity was accompanied by a 300% increase in ACC protein expression. There were no significant differences in ACC activity, ACC protein expression, or AMPK activity in the skeletal muscle of the 12-week JCR:LA-cp rats. Treatment of 12-week JCR:LA-cp rats with MEDICA 16 (an ATP-citrate lyase inhibitor) resulted in a decrease in hepatic ACC and AMPK activities, but had no effect on skeletal muscle ACC and AMPK. Our data suggest that alterations in ACC or AMPK activity in muscle do not contribute to the development of insulin resistance. However, increased liver ACC activity in the JCR:LA-cp rat appears to contribute to the development of lipid abnormalities, although this increase does not appear to occur secondary to a decrease in AMPK activity.

    2001-10-01

    The problem of quality has been a constant issue in every organization.One is always seeking to produce more, to do it at a lower cost, and to do it with better quality. However, in this country, there is no radiographic film quality control system for radiographic services. The tittle that actually gets done is essentially ad hoc and superficial. The implications of this gap, along with some other shortcomings that exist in process as a whole (the state of the x-ray equipment, the adequate to use in order to obtain a radiography, the quality of the film, the processing of the film, the brightness and homogeneity of the viewing boxes, the ability of the radiologist), have a very negative impact on the quality of the medical image, and, as result, to the quality of the medical diagnosis and therapy. It frequently happens that many radiographs have to be repeated, which leads to an increase of the patient's exposure to radiation, as well as of the cost of the procedure for the patient. Low quality radiographs that are not repeated greatly increase the probability of a wrong diagnosis, and consequently, of inadequate therapeutical procedures, thus producing increased incidence of bad outcomes and higher costs. The paradigm proposed in order to establish a system for the measurement of the image's quality is Decision Theory. The problem of the assessment of the image is studied by proposing a Decision Theory approach. The review of the literature reveals a great concern with the quality of the image, along with an absence of an adequate paradigm and several essentially empirical procedures. Image parameters are developed in order to formalize the problem in terms of Decision Theory, and various aspects of image digitalisation are exposed. Finally, a solution is presented, including a protocol for quality control. (author)

    Full Text Available Pharmacies permeate and interconnect various actions developed in different sectors within the complex process of the use of drugs in a hospital. Dispensing failures mean that a breach has occurred in one of the last safety links in the use of drugs. Although most failures do not harm patients, their existence suggests fragility in the process and indicates an increased risk of severe accidents. Present concepts on drug-related incidents may be classified as side effects, adverse effects, and medication errors. Among these are dispensing errors, usually associated with poor safety and inefficient dispensing systems. Factors associated with dispensing errors may be communication failures, problems related to package labels, work overload, the physical structure of the working environment, distraction and interruption, the use of incorrect and outdated information sources and the lack of patient knowledge and education about the drugs they use. So called banal dispensing errors reach significant epidemiological levels. The purpose of this paper, which is part of a study on the occurrence of dispensing errors in the pharmacy of a large hospital, is to review the main concepts that guide studies on adverse effects and to provide an update on dispensing errors.A farmácia hospitalar permeia e interliga várias ações desenvolvidas em diferentes setores no complexo processo de utilização do medicamento dentro do hospital. Falhas na dispensação significam o rompimento de um dos últimos elos na segurança do uso dos medicamentos. Ainda que grande parte dessas falhas não cause danos aos pacientes, sua existência denuncia fragilidade no processo e indica, em uma relação direta, riscos maiores de ocorrência de acidentes graves. Os conceitos atuais dos incidentes relacionados a medicamentos podem ser categorizados em grupos e incluem as reações adversas, os eventos adversos e os erros de medicação. Dentre estes se inclui os erros de dispensa

    Full Text Available The Hartlaub’s & Trinks’ Materia Medica Pura (Reine Arzneimittellehre stands among few large collections of provings owned by the homeopaths. It has never been wholly translated to English, and perhaps to any other language. As a result, few people know and fewest have used it. However this materia medica was instrumental to make Hahnemann’s and Allen’s largest books. Any pathogenetic symptom is always a fact to which time only will add clearness and facility to understanding. Since it wasn’t translated, the homoeopathic repertories, written originally in English, don’t include a large part of its symptoms. Books that aren’t read and published tend to disappear and, in the case we are mentioning, a loss would be large to Homeopathy. The author compares the symptoms of materia medica and repertory. This research is made on original texts and afterwards compared to the translations. So he found, among the symptoms in Hartlaub & Trinks,many symptoms that aren’t in any other next, and connects it to some exemplary cases. Aspects that have been presented confirmed the importance of Hartlaub’s & Trinks’ Materia Medica Pura once it contains symptoms that are not presented in any other text, and correct those that were wrongly translated. The rescue stops being just a bibliophiler preciosity to show itself as a venture when one can find in its symptoms similarities with the patients. So Homeopathy presents itself in all its beauty and capacity of healing.

    Full Text Available China is one of the first countries to use marine materia medica for treating diseases. Ancient books on Chinese herbology, such as Shennong Bencaojing (Shennong’s Classic of Materia Medica, Xinxiu Bencao (Newly Revised Materia Medica and Bencao Gangmu (Compendium of Materia Medica, have detailed more than 110 marine herbs and thousands of marine herbal formulas (including those for Chinese food therapy. A great deal of information on marine herbs and their applications in medicine, collected over thousands of years, has provided an important foundation for modern research in the area of marine drugs. Thanks to these records and references, the research and development of modern Chinese marine drugs continue to evolve and mature. Since the middle of the 20th century, special attention has been paid to traditional Chinese medicine, resulting in a significant increase in the number of newly discovered marine herbs. Comprehensive surveys in the past have also created a wealth of data on the pharmacology, chemistry, biology and ecology of marine medicinal bioresources. After thousands of years of research, historical references to traditional marine herbs are scattered throughout ancient books, local chronicles, medical books, or monographs on medicinal herbs. Unfortunately, there is no systematic way to collate or scientifically verify these references. Furthermore, during the last century, scientists around the world have accumulated large quantities of information on marine natural products, but these are also scattered throughout academic books and journals.

    Touwaide, Alain

    2009-12-01

    Full Text Available This paper deals with the Arabic translation of De materia medica by the Greek author Dioscorides (1st century A.D., particularly the rendering of plant names, which were sometimes properly translated and sometimes transliterated from the Greek. According to a traditional interpretation, the transliteration strategy was used by the translators when they did not know the exact Arabic equivalent of the plant names. I re-examine this interpretation here taking into account the role of plant names in the Greek text and the Andalusian works of botanical lexicography. As a result, I propose to interpret transliterations as a mean used by translators to keep visible the structure of the work, in which plant names played a certain role.

    Este artículo se ocupa de la traducción árabe del texto griego del tratado De materia medica de Dioscórides (siglo I, especialmente de los fitónimos que, en unos casos, fueron traducidos al árabe y, en otros, transliterados del griego. Según la interpretación tradicional, la transliteración era una estrategia utilizada por los traductores cuando no conocían el equivalente exacto árabe de los nombres de las plantas. Se propone en este trabajo una revisión de esta interpretación, teniendo en cuenta el importante papel que los nombres de las plantas desempeñan en el texto griego, así como en las obras de los lexicógrafos y botánicos andalusíes, llegando a la conclusión de que las transliteraciones eran una técnica utilizada por los traductores para mantener visible la estructura general de la obra de Dioscórides, basada en gran parte en la nomenclatura de las plantas.

    Full Text Available Medication error is defined as any type of error in the prescription, transcription, dispensing and administration process which could bring about serious consequences or not. This descriptive and exploratory study assesses four scenarios showing situations from nursing practice. The study group was composed of 256 professionals and 89 questionnaires were analyzed. The answers given by the registered nurses were compared with those of licensed practical nurses and care aids. They should express their opinion if the situations represented a medication error or not, if it had to be communicated to the physician or an incident report had to be written. The two groups showed uniform answers. They expressed the same doubts to label the situation as an error and which measures should be taken, suggesting the need for further discussion on the matter within the institution.El error de medicación se define como cualquier error en el proceso de prescripción, dispensación o administración de una medicación, pudiendo o no traer consecuencias serias.

But we have to confront worsening problems such as lack of safety evidence, immature self - formulation technologies, lack of knowledge about their toxicities, and public misunderstanding, especially for patients with cardiovascular disease (CVD). Therefore, we cardiovascular physicians are requested improve knowledge for CMM preparations and their effects and side effects, supervise and identify the interactions between CMM and Western medicine. Meanwhile, the researchers are also requested to assess the safety and efficacy of CMM through rigorous experimental designs, further improve the quality, safety, and efficacy of CMM, strictly formulate the specification of CMM products, guide the rational use of CMM by clinicians and the general public.

  1. Genetic and functional characterization of a yet-unclassified rhizobial Dtr (DNA-transfer-and-replication) region from a ubiquitous plasmid conjugal system present in Sinorhizobium meliloti, in Sinorhizobium medicae, and in other nonrhizobial Gram-negative bacteria.

    Rhizobia are Gram-negative bacteria that live in soils and associate with leguminous plants to establish nitrogen-fixing symbioses. The ability of these bacteria to undergo horizontal gene transfer (HGT) is thought to be one of the main features to explain both the origin of their symbiotic life-style and the plasticity and dynamics of their genomes. In our laboratory we have previously characterized at the species level the non-pSym plasmid mobilome in Sinorhizobium meliloti, the symbiont of Medicago spp., and have found a high incidence of conjugal activity in many plasmids (Pistorio et al., 2008). In this work we characterized the Dtr (DNA-transfer-and-replication) region of one of those plasmids, pSmeLPU88b. This mobilization region was found to represent a previously unclassified Dtr type in rhizobia (hereafter type-IV), highly ubiquitous in S. meliloti and found in other genera of Gram-negative bacteria as well; including Agrobacterium, Ochrobactrum, and Chelativorans. The oriT of the type-IV Dtr described here could be located by function within a DNA fragment of 278 bp, between the divergent genes parA and mobC. The phylogenetic analysis of the cognate relaxase MobZ indicated that this protein groups close to the previously defined MOB(P3) and MOB(P4) type of enzymes, but is located in a separate and novel cluster that we have designated MOB(P0). Noteworthy, MOB(P0) and MOB(P4) relaxases were frequently associated with plasmids present in rhizospheric soil bacteria. A comparison of the nod-gene locations with the phylogenetic topology of the rhizobial relaxases revealed that the symbiotic genes are found on diverse plasmids bearing any of the four Dtr types, thus indicating that pSym plasmids are not specifically associated with any particular mobilization system. Finally, we demonstrated that the type-IV Dtr promoted the mobilization of plasmids from S. meliloti to Sinorhizobium medicae as well as from these rhizobia to other bacteria by means of their own

These areas can be of social, economic, of engineering, of basic and applied science, etc. With and appropriate handling of computation programs and information can be carried out calculations and simulations of real models, to study them and to solve theoretical or application problems. The processes that contain random variables are susceptible of being approached with the Monte Carlo method. This is a numeric method that, thanks to the improvements in the processors of the computers, it can apply in many tasks more than what was made in the principles of their practical application (at the beginning of the decade of 1950). In this work the application of the Monte Carlo method will be approached in the simulation of the radiation interaction with the matter, to investigate dosimetric aspects of some problems that exist in the medical physics area. Also, contain an introduction about some historical data and some general concepts related with the Monte Carlo simulation are revised. (Author)

    Aim: Several epidemiological studies have suggested that treatment with angiotensin Ⅱ type 1 receptor blocker provided a risk reduction of developing type 2 diabetes. The aim of this study was to investigate whether and how chronic candesartan treatment can attenuate the deleterious influence of the hyperactive local intra-islet renin-angiotensin system in the diabetes state. Methods: Eight-week-old db/db mice were randomized to candesartan 1 mg/kg, candesartan 10mg/kg, manidipine 10 mg/kg, or placebo via gavage for 6 weeks. Their age-matched nondiabetic littermates db/m mice were treated with placebo and acted as nondia-betic controls. After 6 weeks' treatment, an intraperitoneal glucose tolerance test, immunohistochemical staining of oxidative stress markers, insulin, CD31, azan staining and an electron microscopy observation were performed. Results: Chronic candesartan treatment provided an improvement of glucose tolerance, and greatly rescued islet β-cell mass. Candesartan treatment also notably decreased staining intensity of oxidative stress markers, as well as attenuating intra-islet fibrosis and improving blood supply in the islet. In the electron microscopy observation, candesartan-treated animals exhibited improved granulation and less remarkable endoplasmic reticulum and Golgi bodies; furthermore, candesartan treatment greatly relieved the swelling of mitochondria to nearly normal. Both the benefits of reducing oxidative stress and ultra structure protection were in a dose-dependent and blood pressure-independent manner. Conclusion: After diabetes was initiated, candesartan treatment could not reverse the state of diabetes, but it effectively improved glucose tolerance and protected β-cell function by attenuating oxidative stress, islet fibrosis, sparsity of blood supply and ultrastructure disruption in a dose-dependent and blood pressure-independent manner.

    Ionizing radiation for diagnostic purposes are an indispensable tool in modern medicine. The increasing use of computed tomography (CT) in children and adolescents is of concern both from the point of view of radio-protection and public health. children are more sensitive to the carcinogenic effects of ionizing radiation than adults. Children also have a higher life expectancy to show any detrimental effect. Furthermore, because of their smaller mass, CT scans in children receiving higher doses of radiation in specific organs in adults.

O midazolam é o hipnótico mais utilizado como medicação pré-anestésica e suas interações medicamentosas nos pacientes com PC são desconhecidas. O objetivo deste estudo foi avaliar o midazolam como medicação pré-anestésica no BIS dos pacientes com PC em uso crônico de anticonvulsivantes. MÉTODO: Foram avaliados três grupos de pacientes: PC sem uso de anticonvulsivantes, PC em uso de anticonvulsivante e outro grupo sem doença e sem uso de medicações (Grupo Controle. Na véspera da cirurgia, com os pacientes despertos e em decúbito dorsal, foi colocado o monitor do BIS e foram registrados os valores basais do BIS. No dia seguinte, 40 minutos antes da cirurgia, os pacientes receberam 0,6 mg.kg-1 de midazolam por via oral. Antes do início da anestesia, foi realizado o mesmo procedimento para registro do BIS, após o uso do midazolam. RESULTADOS: Foram estudados 107 pacientes - 39 pacientes do Grupo Controle e 68 com diagnóstico de PC. Desses, 17 faziam uso de anticonvulsivante. Com relação ao valor médio de BIS após o uso do midazolam, não houve diferença entres os pacientes do Grupo Controle e do Grupo PC que não tomavam anticonvulsivante, enquanto entre os pacientes que faziam uso de anticonvulsivantes houve diferença (p = 0,003. A possibilidade de diminuição do BIS após o uso do midazolam aumenta de acordo com o número de anticonvulsivantes usados pelo paciente. CONCLUSÕES: O uso crônico de anticonvulsivante associado ao midazolam via oral como medicação pré-anestésica pode levar à diminuição dos valores de BIS, configurando níveis profundos de hipnose.JUSTIFICATIVA Y OBJETIVOS: Los pacientes con parálisis cerebral (PC, a menudo usan fármacos para el tratamiento de enfermedades concomitantes, como las convulsiones.

The objective was to describe the characteristics of prescription according to patients‘ expectations and prescriptors‘ behavior. Our results indicate that there were no significant differences between the answers of physicians and dentists. Both groups prescribe by taking into account patients‘ expectations and to a lesser extent their personal interest; they seem to pay little attention to adverse medicine reactions. The university community and prescriptors know the risks and disadvantages involved in the inappropriate use of medicaments; however, they use them indiscriminately in some situations, without a real justification.

    Objective To study the effects of Chinese materia medica (CMM) combined chemotherapy on the recurrence, metastasis, and the disease free survival (DFS) of stage Ⅱ and Ⅲ colorectal cancer (CC) patients after radical cure. Methods Recruited were 366 inpatients and outpatients with stage Ⅱand Ⅲ colorectal cancer (CC) from Changhai Hospital, Second Military Medical University, and Tumor Department of Longhua Hospital, Shanghai University of Traditional Chinese Medicine from January 2002 to December 2008. A non-ran-domized concurrent control method was adopted. Patients were assigned to the combination group (treated by CMM + chemotherapy, 189 cases) and the chemotherapy group (177 cases) according to whether they were willing to receive the CMM treatment for more than 6 successive months. By using follow-ups at clinics, by letter, and by telephone, the DFS, 1-, 2-, 3-, and 5-year DFS ratios were observed. The correlations between DFS and the gender, age, tumor location, staging of clinical pathology, pathological type, chemotherapeutic cycle, radiotherapy, CMM treatment, end point event ( recurrence and metastasis) were analyzed. Results The recurrence or metastasis occurred in 145 cases (39. 61%) of the 366 patients. Of them, local recurrence occurred in 17 cases (11.72%), liver metastasis in 45 cases (31.03%), lung metastasis in 52 cases (35. 86%) ,and metastasis in other parts in 53 cases (36. 55%). Results of one-factor analysis showed six fac-tors such as the tumor location, pathological type, staging of clinical pathology, chemotherapeutic cycle, radio-therapy, and CMM treatment were correlated with the DFS, showing statistical difference (P<0. 01, P<0. 05).Results of multifactor analysis showed staging of clinical pathology, chemotherapeutic cycle, and CMM treatment were correlated with the DFS, showing statistical difference ( P<0. 01).

    Full Text Available Indomethacin suppositories were prepared by using water-soluble and oil soluble suppository bases, and evaluated for in vitro release by USP I and modified continuous flow through bead bed apparatus. Effect of the Tween 80 (1% and 5% was further studied on in vitro release of the medicament. Release rate was good in water-soluble suppositories bases in comparison to oil soluble suppositories bases. Release was found to be greater in modified continuous flow through bead bed apparatus. When surfactant was used in low concentration then release rate was much greater, as compared to high concentration. When stability studies were performed on the prepared indomethacin suppositories it was found that suppositories made by water-soluble base had no significant changes while suppositories prepared by oil soluble bases, had some signs of instability.

    Two epoxy polymers based on diglycidyl ether of bisphenol A (DGEBA), cured with piperidine (Pip) and 4,4'-diamino-3,3'-dimethyldicyclohexylmethane (3DCM), were characterized before and after treatment with γ irradiation. The changes in the mechanical and thermal properties were studied by elastic modulus, glass transition temperature and degradation temperature measurements. A dose of 50 kGy of irradiation caused subtle variations in properties such as rigidity and stability, which are relevant from the fundamental point of view. The variations do not imply on negative impact when considering the stage of sterilization during the use of these systems as a biomaterial in the medical area. (author)

    After the terrorist attack in New York, USA, in 2001, there was a worldwide concern about possible attacks using radioactive material in conventional detonators, called as Radiological Dispersal Device (RDD) or 'dirty bomb'. Several studies have been and are being made to form a global knowledge about this type of event. As until now, fortunately, there has not been an event with RDD, the Goiania Radiological Accident in Brazil, 1987, is used as a reference for decision-making. Several teams with technical experts should act in an event with RDD, but the medical staffs who respond quickly to the event must be properly protected from the harmful effects of radiation. Based on the radiological protection experts performance during the Goiania accident and the knowledge from lessons learned of many radiological accidents worldwide, this work presents an adaptation of the radiation protection actions for an event with RDD that helps a medical team as primary responders. The following aspects are presented: the problem of radioactive contamination from the explosion of the device in underground environment, the actions of the first responders and evaluation of health radiation effects. This work was based on specialized articles and papers about radiological accidents and RDD; as well as personal communication and academic information of the Institute of Radiation Protection and Dosimetry. The radiation protection actions, adapted to a terrorist attack event with RDD, have as a scenario a subway station in the capital. The main results are: the use of the basic radiation protection principle of time because there is no condition to take care of a patient keeping distance or using a shielding; the use of full appropriate protection cloths for contaminating materials ensuring the physical safety of professionals, and the medical team monitoring at the end of a medical procedure, checking for surface contamination. The main conclusion is that all medical actions

    The dosimetry by thermoluminescence (Tl) is applied in the entire world for the dosimetry of ionizing radiations specially to personal and medical dosimetry. This dosimetry method has been very interesting for measures in vivo because the Tl dosimeters have the advantage of being very sensitive in a very small volume and they are also equivalent to tissue and they do not need additional accessories (for example, cable, electrometer, etc.) The main characteristics of the diverse Tl materials to be used in the radiation measures and practical applications are: the Tl curve, the share homogeneity, the signal stability after the irradiation, precision and exactitude, the response in function with the dose and the energy influence. In this work a brief summary of the advances of the radiations dosimetry is presented by means of the thermally stimulated luminescence and its application to the dosimetry in radiotherapy. (Author)

    Análisis Critico Del Panorama Actual.

    El conocimiento biomédico ha crecido a una velocidad enorme en el presente siglo y en las últimas décadas ha avanzado mucho más que en el curso de toda su historia.

    También en el presente siglo se han desarrollado en América Latina los conceptos de organización y de economía de la atención médica. en la medida que la opinión pública y los legisladores enfocan su atención hacia los costos del cuidado médico para el ciudadano. la financiación de los hospitales públicos y privados y la obligación del estado de proveer atención para aquellas personas sin acceso a servicios privados. La economía médica se convirtió en un área respetable, a la vez que básica y necesaria desde el punto de vista de la investigación, dentro del contexto general de las actividades médicas y de salud (1. Sin embargo, en otras latitudes ha surgido un peligroso fenómeno, el de la industria de la salud, que provee servicios con ánimo de lucro, dando lugar al denominado complejo médico-industrial que puede llegar a confundir los intereses del público con el de los inversionistas (8. Es así como aspectos relativos a la organización y a la economía de la atención médica son hoy un hecho de la vida diaria, allado de los tradicionales esfuerzos por mantener la excelencia en la calidad de la educación, la investigación y la prestación de servicios.

    Estos fenómenos, de ocurrencia universal, también han sido observados en Colombia y en la América Latina. Pero en la medida que el desarrollo socioeconómico de la atención médica prima como preocupación estatal y aparece prioritario en el panorama político como reflejo de justas aspiraciones ciudadanas, lo cual repercute en el crecimiento de la organización de la seguridad social como servicio público, el sector de la educación médica. representado por las facultades de medicina y los hospitales de enseñanza, públicos y privados, sufre un alarmante deterioro no sólo en su operación y desarrollo. sino aún en su misma filosofía y principios fundamentales (15.

Mucho del progreso alcanzado en el conocimiento biológico y en la aplicación de modernas tecnologías, lo cual significa toda una nueva perspectiva de la medicina y una nueva concepción de la educación médica, aún no ha llegado a nuestras facultades. Lamentablemente parece que buena parte de nuestro profesorado no ha registrado el prodigioso panorama de la nueva biología.

    Lo más sobresaliente de la evolución histórica de la medicina en la segunda mitad del presente siglo. es el vertiginoso avance de la medicina como ciencia. La bioquímica celular, y ahora la biología en los niveles moleculares y submoleculares, han explotado como el nuevo y sobrecogedor campo que gobierna la educación y la investigación médicas. Philip Applewhite de Yale se refiere a “los dioses moleculares” (2, al señalar como la biología molecular significa algo que va más allá de la simple estructura y función orgánica. para determinar aún el mismo comportamiento humano: “nuestro comportamiento es controlado por moléculas, y por nada más … estas moléculas actúan como dioses. por así decir, gobernándonos aún más de lo que podemos imaginar … nuestro comportamiento se debe más a los eventos moleculares que ocurren

    Full Text Available As infecções intestinais por espiroquetas em suínos, na fase que se segue ao alojamento nos prédios de recria, são predispostas por fatores como o estresse da movimentação, mistura entre animais imunes e excretores com leitões não imunes, deficiências nas condições ambientais e troca no tipo da ração usada. Para contrabalançar esses efeitos, é uma prática rotineira a inclusão de antimicrobianos à ração, em doses de promoção de crescimento ou de controle. O presente trabalho avaliou a ocorrência da infecção por Brachyspira spp. em rebanhos suínos do Estado do Rio Grande do Sul, tentando relacionar com o tipo de programa de uso de antimicrobianos adotado. Foram examinados 393 suabes retais colhidos de 38 granjas do RS (22 usando rações medicadas e 16 com ração sem medicação. A B. hyodysenteriae e B. pilosicoli foram detectadas respectivamente em 0% e 6,25% das granjas medicadas e de 31,8% e 45,5% das granjas não medicadas. Entre os suabes examinados, a B. hyodysenteriae e B. pilosicoli estavam presentes respectivamente em 0 e 0,6% dos materiais colhidos de granjas medicadas e de 3,9% e 7,3% em granjas não medicadas. O presente trabalho suporta a opinião de diversos autores que sugeriram a influência direta da inclusão de antimicrobianos à ração em doses de promoção de crescimento ou em dose de controle e a ocorrência de diarréias espiroquetais em leitões. Entretanto, pelas características multifatoriais desse tipo de patologia, seriam necessários estudos adicionais abrangendo um número maior de variáveis entre aquelas possivelmente envolvidas no desencadeamento das diarréias, antes que fosse obtida uma conclusão definitiva.Intestinal spirochaetal infections in pigs following transportation to growing facilities is predisposed by stressful factors such as contact between carriers and non-immune piglets, defficient environment and diet changes.

    At present, studies on traditional Chinese medicine (TCM) properties are mostly restricted to a single or two kinds of medicinal properties, but deviated from the holism of the theoretical system of TCMs. In this paper, the characteristics of pharmacological effects of different property combinations of TCMs distributing in the stomach meridian were take as the study objective. The data of properties of TCMs distributing in the stomach meridian was collected from the Pharmacopoeia of the People's Republic of China (2005). The data of pharmacological effects of TCMs distributing in the stomach meridian was collected from all of literatures recorded in Chinese Journal Full-text Database (CNKI) since 1980, Science of Chinese Materia Medica (Yan Zhenghua, People's Medical Publishing House, 2006) and Clinical Science of Chinese Materia Medica (Gao Xuemin, Zhong Gansheng, Hebei Science and Technology Publishing House, 2005). The corresponding pharmacological effects of property combinations of TCMs distributing in the stomach meridian was mined by the method of association rules. The results of the association rules were consistent with the empirical knowledge, and showed that different medicinal property combinations had respective pharmacological characteristics, including differences and similarities in pharmacological effects of different medicinal property combinations. Medicinal property combinations with identical four properties or five tastes showed similar pharmacological effects; whereas medicinal property combinations with different four properties or five tastes showed differentiated pharmacological effects. However, medicinal property combinations with different four properties or five tastes could also show similar pharmacological effects. In this study, the medicinal property theory and the pharmacological effects of TCMs were combined to reveal the main characteristics and regularity of pharmacological effects of TCMs distributing in the stomach meridian

    High levels of the novel inflammatory marker YKL-40 have been demonstrated in inflammatory environments and in remodeling of the extracellular matrix. Both are key components in atrial wall remodeling in atrial fibrillation (AF). We studied the relation between rhythm outcome after electrical cardioversion (ECV) for persistent AF and serum levels of YKL-40. A secondary point of interest was a potential effect of the angiotensin receptor blocker candesartan on YKL-40 levels. In the Candesartan in the Prevention of Relapsing Atrial Fibrillation (CAPRAF) study, 171 patients with persistent AF were randomized to receive candesartan 8mg once daily or placebo for 3-6 weeks before ECV and candesartan 16mg once daily or placebo for 6 months after ECV. Serum levels of YKL-40 were measured in fasting blood samples collected at baseline and at end of the study. Mean age was 64±11 years, and 39 (22.8%) were women. Sinus rhythm was maintained for 6 months after ECV in 41 (23.9%). Baseline levels of YKL-40 were significantly correlated to age (Spearmans rho; rs=0.442; p<0.001), CHA2DS2-VASc(1) score (rs=0.256; p<0.001) and left atrial diameter (rs=0.185; p=0.017). By use of Kaplan-Meier quartile analysis of baseline YKL-40 levels, no relation between YKL-40 levels and risk of AF recurrence was found. End of study YKL-40 levels were unchanged from baseline, both in patients with AF recurrence and those maintaining sinus rhythm for 6 months. Treatment with candesartan had no influence on serum YKL-40 levels.

In 2013 and 2014, the manipulating experiment was established in pear orchard. The synergistic manipulation of pear intercropping Trifolium repens and Platycodon grandiflorum combining with the biological agent on the population dynamics of P. chinensis and their predators were determined systematically. The results showed that the total population size of predators in the areas of intercropping T. repens and P. grandiflorum were higher than that in the bare area by artificial weeding. In 2013, the predator of dominant species was O. minutes in the area of intercropping T. repens and P. fuscipes was in the area of intercropping P. grandi-florum. In 2014, E. graminicolum and T. chinensis dominated in the area of intercropping T. repens;H. axyridis, P. japonica, E. balteata and E. graminicolum dominated in the area of intercropping P. grandiflorum. In 2013, the nymphae populations of P. chinensi in the areas of both intercropping T. repens and P. grandiflorum combining with the biological agent on June 18 were significantly higher and on other dates were not significant difference compared with the bare area with conventional pesticide application. In 2014, the population densities of both adults and nymphae of P. chinensis were significantly lower in the areas of both intercropping T. repens and P. grandiflorum combining with the bio-logical agent than that in the bare area with conventional pesticide application during all the period of P. chinensis occurence. This research demonstrated that the measure of intercropping perennial T. repens and P. grandiflorum in pear orchard one year later combining with appli-cation of the biological agent SOVONA could substitute half amount of chemical pesticide usage. The synergistic manipulation effect of this measure was significantly higher

    Full Text Available Introduction. Because apical periodontitis is recognizably an infectious disease, elimination or reduction of intracanal bacteria is of utmost importance for optimum treatment outcome. Objective. The prevalence of Enterococcus faecalis and Porphyromonas gingivalis in infected root canals was studied Also, the effect of endodontic therapy by using intracanal medicaments, calcium hydroxide paste (CH or gutta-percha points containing calcium hydroxide (CH-GP or chlorhexidine (CHX-GP on these microorganisms was assessed by polymerase chain reaction (PCR assay. Methods. Fifty-one patients with chronic apical periodontitis were randomly allocated in one of the following groups according to the intracanal medicament used: CH, CH-GP and CHX-GP group. Bacterial samples were taken upon access (S1, after chemomechanical instrumentation (S2 and after 15-day medication (S3. PCR assay was used to detect the presence of selected bacteria. Results. E. faecalis was detected in 49% (25/51 and P. gingivalis in 17.6% (9/51 of the samples. Samples which showed no bacterial presence at S1 were excluded from further analysis. Overall analysis of all 29 samples revealed significant differences between S1 and S2 (p<0.001, S2 and S3 (p<0.05, and S1 and S3 (p<0.001. When distinction was made between the intracanal medications, there was a significant difference in the number of PCR positive samples between S1 and S2, S1 and S3, but not between S2 and S3 samples. Conclusion. E. faecalis is more prevalent than P. gingivalis in primary endodontic infection. Intracanal medication in conduction with instrumentation and irrigation efficiently eliminates E. faecalis and P. gingivalis from infected root canals.

    Pain is a well known phenomenon in posttraumatic spinal cord injuries. Nearly 10% of the patients develop most severe, invalidizing, as a rule neurogenic pain conditions that are hardly accessible to conventional therapies. A pilot study was therefore conducted with 10 paraplegics and tetraplegics suffering chronic pain, investigating how vibration supported music therapy with the Musica Medica method affected pain experience, tension/relaxation and well-being. In addition to subjective experience, we measured physiological parameters (finger tip skin temperature, electrodermal activity, heart rate, respiration frequency) during the therapy sessions. All patients had a high acceptance of the method which throughout the group had brought about an increase in relaxation and well-being as well as a decrease of pain experience. The autonomic nervous system variables correlated with relaxation and in addition pointed to an activating impact of the therapy chosen.

    Full Text Available The inhalation route for administration of medicaments is becoming more and more popular in recent years. The reason is non-invasiveness of the method and instantaneous absorption of drugs to the blood circulation. It is necessary to deliver exact amount of drug to the specific segment because of occurrence of diverse diseases in different segments of lungs. The aim of our work is to contribute to better understanding of transport and deposition of aerosolized drugs in lungs and hence to more effective treatment of respiratory diseases due to the targeted drug delivery. We provided measurements of aerosol deposition in segmented realistic model of lungs without a mouth cavity. Monodisperse particles marked with fluorescein were supplied to the model. The model was then disassembled to segments and each segment was rinsed with isopropanol, whereby fluorescent samples were created. Each sample was analysed by fluorometer and an amount of aerosol deposited in the segment was calculated. Experiences obtained by this study were used for creation of a new model with the mouth cavity. This model will be used for future studies with porous and fiber aerosols.

    Full Text Available The absence of sperm in the seminal fluid is known as azoospermia. This medical condition is in a direct association with male's infertility. A complete medical history, physical examination, tests of selected hormones and tests for male fertility (including sperm analysis are used for the diagnosis of azoospermia. The number of 1314 men, with fertility problems, at age between 20 and 67 years, were included in this investigation. The data obtained in the study showed that azoospermia occurred in 5.25% of the group studied. The Klinefelter syndrome was cytogenetically diagnosed in 2.9% of the male individuals. There was found that 44.3% of males with azoospermia have been smokers, 7.1% of them – addicted to drugs, 17.1% have taken different medicaments, 4.35% – have had radiation therapy, 4.35% have had a diagnosis "varicocele". The volume of the ejaculate was less than 2 ml in 37.68% of the men and more than 7 ml in 2.89% of them.

    Full Text Available Empregou-se a associação midazolam e detomidina para indução de anestesia com cetamina em 16 potros, machos e fêmeas, entre três e seis meses de idade, distribuídos aleatória e equitativamente em dois grupos (GI e GII. A todos os animais foram administrados midazolam, via intramuscular, na dose de 0,2mg/kg, e após 15 minutos, detomidina, via intravenosa, na dose de 0,02mg/kg. Os animais do GII receberam cetamina pela via intravenosa, dose 2,0mg/kg, três minutos após a administração de detomidina. Quinze minutos após o midazolam, ocorreram sedação e ligeira ataxia, e dois minutos após a administração da detomidina, decúbito lateral em todos os potros, com miorrelaxamento e presença dos reflexos de deglutição e miorrelaxamento, anal e oculo-palpebral. A associação midazolam/detomidina e cetamina provocou ausência dos reflexos de deglutição. Para todos os animais, o tempo de recuperação foi de 45-60 minutos, e temperatura retal e frequência respiratória permaneceram estáveis. Ocorreram bradicardia, bloqueio atrioventricular de segundo grau e aumento das pressões arteriais sistólica, diastólica e média após dois minutos da administração da detomidina. A associação midazolam/detomidina e cetamina demonstrou ser um método eficiente e seguro para a anestesia de potros hígidos.A combination of midazolam, 0.2mg/kg body weight given via intramuscular, and detomidine, 0.02mg/kg body weight given via intravenous (IV, was evaluated as a method for induction of anesthesia with ketamine, 2.0mg/kg body weight given via IV in foals. Sixteen male and female foals aging from three to six-month old were distributed into two groups. Both groups were first injected with midazolam and with detomidine 15 minutes later. Three minutes later, ketamine was injected in the foals. Sedation and light ataxia were observed 15 minutes after midazolam administration. Bradycardia, atrioventricular block, increased blood pressure, lateral recumbency, and muscle relaxation were observed two minutes after detomidine. At that time, the oculopalpebral, anal, and cogh reflexes were present. The association of midazolam/detomidine and ketamine caused absence of the swallow reflexes. The recovery time was from 45 to 60 minutes for animals from GI and GII groups, respectively. Respiratory rate and body temperature remained unchanged. The combination of midazolam/detomidine and ketamine is a safe, good, and efficient method for anesthesia in healthy foals.

    Full Text Available Angiotensin II (Ang II receptor blockers are the newest class of antihypertensive drugs to be developed. No large-scale clinical trials have been performed to evaluate their efficacy alone, or in combination with other drugs. A large-scale, eight week, open-label, non-placebo-controlled, single-arm trial evaluated the efficacy, tolerability and dose-response of candesartan cilexetil, 16—32 mg once-daily, either as monotherapy or as part of combination therapy, in a diverse hypertensive population in actual practice settings. 6465 patients with high blood pressure, of whom 52% were female and 16% African American, with a mean age of 58 years, were included. 5446 patients had essential hypertension and 1014 patients had isolated systolic hypertension. In order to be included in this study, patients had either untreated or uncontrolled hypertension (systolic blood pressure (SBP 140—179 mmHg and/or diastolic blood pressure (DBP 90—109 mmHg inclusive at baseline, despite a variety of other antihypertensive drugs. Of the 5156 patients with essential hypertension and at least one post baseline efficacy measurement, the mean pretreatment blood pressure (BP was 156/97 mmHg. Candesartan cilexetil monotherapy reduced mean SBP/DBP by 18.0/12.2 mmHg. Similarly, in the 964 patients with isolated systolic hypertension and at least one post baseline efficacy measurement, candesartan cilexetil monotherapy reduced SBP/DBP from 158/81 by 16.5/4.5 mmHg. Candesartan cilexetil was similarly effective when employed as add-on therapy. When added to baseline antihypertensive medication in 51% of the patients with essential hypertension not achieving BP control, additional reduction in BP was achieved regardless of the background therapy, including diuretics (17.8/11.7 mmHg calcium antagonists (16.6/11.2 mmHg, beta-blockers (16.5/10.4 mmHg, angiotensin-converting enzyme inhibitors (ACE-I (15.3/10.0 mmHg, and alpha blockers (16.4/10.4 mmHg.

    The magnetic ordering temperature and the magnitude of the magnetic fields at the iron sites of YIG can be influenced by substituting, either partially or totally, the Fe{sup 3+} ions at the octahedral and/or the tetrahedral sites with magnetic or diamagnetic ions, and/or by substitution the Y{sup 3+} ions at the dodecahedral sites with magnetic rare earth ions. It has been known for some time that Moessbauer spectroscopy is a powerful method by which iron-containing garnets can be studied. We report here on the synthesis of the compounds with garnet-related structures of composition Y{sub 3}Fe{sub 4.5}Cr{sub 0.5}O{sub 12} and its examination by {sup 57}Fe Moessbauer spectroscopy. The chromium in compounds of the Y{sub 3}Fe{sub 4.5}Cr{sub 0.5}O{sub 12} is distributed at an octahedral site. The Moessbauer spectra can be analyzed using 3 or 4 sets of six Lorentzians with increasing amount of Cr{sup 3+} compounds in this system. It results from the distribution ({sub 4}C{sub n}) of Fe{sup 3+} and Cr{sup 3+} at an octahedral site. A comparative study of ferrous tablets of Dynabi was carried out using Moessbauer spectroscopy. The obtained results revealed the presence of ferrous (Fe{sup 2+}) gluconate and ferrous fumarate in a sample. This observation is important to better control the iron state in such medicaments because their pharmaceutical effect in the body is related to the form and valence of iron. The Cr-containing yttrium iron garnet (YIG), and the exchange interactions and site distributions were studied using {sup 57}Fe Moessbauer spectroscopy. The obtained results revealed the presence of ferrous (Fe{sup 2+}) gluconate and ferrous fumarate in the sample. This observation is important better control the iron state in such medicaments because their pharmaceutical effect in the body is related to the form and valence of iron.

    Full Text Available In chronic renal failure, hypoxia of renal tissue is thought to be the common final pathway leading to end-stage renal failure. In this study the effects of hachimijiogan, a Kampo formula, were studied with respect to hypoxia-inducible factor (HIF. Using remnant kidney rats, we studied the effects of hachimijiogan on renal function in comparison with angiotensin II receptor blocker. The result showed that oral administration of hachimijiogan for seven days suppressed urinary protein excretion and urinary 8-OHdG, a marker of antioxidant activity, equally as well as oral administration of candesartan cilexetil. In contrast, the protein volume of HIF-1α in the renal cortex was not increased in the candesartan cilexetil group, but that in the hachimijiogan group was increased. In immunohistochemical studies as well, the expression of HIF-1α of the high-dose hachimijiogan group increased compared to that of the control group. Vascular endothelial growth factor and glucose transporter 1, target genes of HIF-1α, were also increased in the hachimijiogan group. These results suggest that hachimijiogan produces a protective effect by a mechanism different from that of candesartan cilexetil.

    2006-07-01

    Purpose: To study the effects of drug concentration and spatial distribution of the medicament, in porous solid dosage forms, on the kinetics and total yield of drug release. Methods: Cubic networks are used as models of drug release systems. They were constructed by means of the dual site-bond model framework, which allows a substrate to have adequate geometrical and topological distribution of its pore elements. Drug particles can move inside the networks by following a random walk model with excluded volume interactions between the particles. The drug release time evolution for different drug concentration and different initial drug spatial distribution has been monitored. Results: The numerical results show that in all the studied cases, drug release presents an anomalous behavior, and the consequences of the matrix structural properties, i.e., drug spatial distribution and drug concentration, on the drug release profile have been quantified. Conclusions: The Weibull function provides a simple connection between the model parameters and the microstructure of the drug release device. A critical modeling of drug release from matrix-type delivery systems is important in order to understand the transport mechanisms that are implicated, and to predict the effect of the device design parameters on the release rate.

    Full Text Available Introduction: Multiple treatment protocols are available to the Indian endodontist. Hence a survey is required to recognize the common trends in endodontics and set a basic standard of treatment. Aims and Objectives: The aim of this article is to present practice trends among Indian endodontists and compare the same with established practice trends internationally through various surveys that have been conducted respectively. Materials and Methods: Questionnaires were mailed to 1085 endodontists in dental schools and private practice in India. A response rate of 42% was observed. The data was analyzed and compared with other studies. Results: Most of the endodontists in India follow the basic protocols and techniques in their practices. 40% of the Endodontists preferred digital radiography technique. 2.5% NaOCl is the most preferred irrigant of choice for primary root canal treatment and 2% chlorhexidine in retreatment cases. Calcium hydroxide was the most preferred intracanal medicament in all clinical situations. Lateral compaction (70.8% was the most widely used method. AH Plus was the most preferred root canal sealer (46.6%. Conclusion: Indian endodontists are following the basic protocol but when compared to other studies there were concepts like, the use of rubber dam and microscope which need to be improved and raised to a level that ensures international standards in clinical practice.

    The formation of urinary stones, known as nephrolithiasis or urolithiasis, is a serious, debilitating problem throughout the world. Struvite—NH4MgPO4·6H2O, ammonium magnesium phosphate hexahydrate, is one of the components of urinary stones (calculi). Struvite crystals with different morphologies were grown by in vitro single diffusion gel growth technique with different growth parameters. The crystals were characterized by powder XRD, FT-IR, thermal analysis and dielectric study. The powder XRD results of struvite confirmed the orthorhombic crystal structure. The FT-IR spectrum proved the presence of water of hydration, metal-oxygen bond, N-H bond and P-O bond. For thermal analysis TGA, DTA and DSC were carried out simultaneously. The kinetic and thermodynamic parameters of dehydration/decomposition process were calculated. Vickers micro-hardness and related mechanical parameters were also calculated. The in vitro growth inhibition studies of struvite by the juice of Citrus medica Linn as well as the herbal extracts of Commiphora wightii, Boerhaavia diffusa Linn and Rotula aquatica Lour were carried out and found potent inhibitors of struvite.

    Full Text Available Aim: To evaluate and compare the regenerative potential of natural autologous scaffolds (blood clot and platelet rich fibrin [PRF] with artificial scaffolds (commercially available collagen and poly-lactic-co-glycolic acid [PLGA] polymer in inducing apexogenesis in necrotic immature permanent teeth. Materials and Methods: Necrotic immature permanent maxillary incisors with or without radiographic evidence of periapical lesion were included. Access opening was done under rubber dam isolation. Canal disinfection was done using minimal instrumentation, copious irrigation, and triple antibiotic paste as interappointment medicament for 4 weeks. After 4 weeks, asymptomatic teeth were divided into four groups on the basis of scaffolds used for revascularization procedure: Group I (blood clot; Group II (PRF; Group III (collagen; Group IV (PLGA. The clinical and radiographic evaluations of teeth were done at 6 and 12 months after the procedure and compared with baseline records. Result: Clinically, patients were completely asymptomatic throughout the study period. Radiographically, all cases showed improvement in terms of periapical healing, apical closure, root lengthening, and dentinal wall thickening. PRF and collagen gave better results than blood clot and PLGA in terms of periapical healing, apical closure, and dentinal wall thickening. Conclusion: Revascularization procedure is more effective and conservative over apexification in the management of necrotic immature permanent teeth. This study has shown that PRF and collagen are better scaffolds than blood clot and PLGA for inducing apexogenesis in immature necrotic permanent teeth.

    Full Text Available The antibacterial activity of β-lactam derived polycyclic fused pyrrolidine/pyrrolizidine derivatives synthesized by 1, 3-dipolar cycloaddition reaction was evaluated against microbes involved in dental infection. Fifteen compounds were screened; among them compound 3 showed efficient antibacterial activity in an ex vivo dentinal tubule model and in vivo mice infectious model. In silico docking studies showed greater affinity to penicillin binding protein. Cell damage was observed under Scanning Electron Microscopy (SEM which was further proved by Confocal Laser Scanning Microscope (CLSM and quantified using Flow Cytometry by PI up-take. Compound 3 treated E. faecalis showed ROS generation and loss of membrane integrity was quantified by flow cytometry. Compound 3 was also found to be active against resistant E. faecalis strains isolated from failed root canal treatment cases. Further, compound 3 was found to be hemocompatible, not cytotoxic to normal mammalian NIH 3T3 cells and non mutagenic. It was concluded that β-lactam compound 3 exhibited promising antibacterial activity against E. faecalis involved in root canal infections and the mechanism of action was deciphered. The results of this research can be further implicated in the development of potent antibacterial medicaments with applications in dentistry.

    Radiation sterilization technology is more actively used now that any time because of its many advantages. Gamma radiation has high penetrating power, relatively low chemical reactivity and causes small temperature rise. But on the other hand radiosterilization can lead to radiolytic products appearing, in example free radicals. Free radicals in radiative sterilized sisomicin, tobramycin and paromomycin were studied by electron paramagnetic resonance (EPR) spectroscopy. Dose of gamma irradiation of 25kGy was used. Concentrations and properties of free radicals in irradiated antibiotics were studied. EPR spectra were recorded for samples stored in air and argon. For gamma irradiated antibiotics strong EPR lines were recorded. One- and two-exponential functions were fitted to experimental points during testing and researching of time influence of the antibiotics storage to studied parameters of EPR lines. Our study of free radicals in radiosterilized antibiotics indicates the need for characterization of medicinal substances prior to sterilization process using EPR values. We propose the concentration of free radicals and other spectroscopic parameters as useful factors to select the optimal type of sterilization for the individual drug. The important parameters are i.a. the τ time constants and K constants of exponential functions. Time constants τ give us information about the speed of free radicals concentration decrease in radiated medicinal substances. The constant K(0) shows the free radicals concentration in irradiated medicament after long time of storage.

    Dietary sodium, the main determinant of the pharmacodynamic response to renin-angiotensin system blockade, influences the pharmacokinetics of various cardiovascular drugs. We compared the effect of contrasted sodium diets on the pharmacokinetics of single oral doses of 8 mg candesartan cilexetil, 160 mg valsartan, 10 mg ramipril, and 50 mg atenolol administered to 64 (16 per group) normotensive male subjects randomly assigned to sodium depletion (SD) or sodium repletion (SR) in a crossover study. Pharmacodynamic response was assessed as the increase in plasma renin concentration for renin-angiotensin system blockers and electrocardiographic changes in PR interval duration for atenolol. The area under the curve (AUC) for plasma candesartan and atenolol concentrations was significantly lower for SR than for SD (respective ratios of AUC0-∞: 0.74; [90% CI, 0.66-0.82] and 0.69 [90% CI, 0.54-0.88], respectively), indicating a lack of bioequivalence between SR and SD. SR did not affect the pharmacokinetics of valsartan or ramipril. The increase in plasma renin concentration with the 3 renin-angiotensin system blockers was 10 times lower during the SR than the SD period. In the multiple regression analysis, the AUC0-24 of plasma drug concentration explained plasma renin concentration for candesartan (P=0.8882/P=0.0368) during the SR and SD periods, respectively. The atenolol-induced lengthening of PR interval was fully reversed by SR. Thus, sodium balance modulates the pharmacokinetics of candesartan cilexetil and atenolol, with measurable effects on the selected pharmacodynamic end points.

    Objective To assess the effects of acupuncture combined Chinese materia medica for tonify-ing Shen and soothing Gan (CMMTSSG) on the anxiety and depression o1 patients with in vitro fertilization and embryo transplantation (IVF-ET), and to observe the treatment outcomes. Methods Totally 97 IVF-ET patients were randomly assigned to two groups, the acupuncture combined CMMTSSG (Group A, 51 cases) and the Western medicine treatment group (Group 3, 46 cases). The long protocol of iVF-ET in a mid tuteal phase was performed in all patients. Patients in Group A received acupuncture and CMMTSSG (Erzhi Tiangui Granule and Xiaoyao Granule) during the process of ovarian hyperstimulation, while those in Group B only received the rou-tines of IVF-ET. The improvement of Shen deficiency Gan depression syndrome (SDGDS) between alter and before treatment were observed in the two groups. The changes of self-rating anxiety scale (SAS) and Beck de-pression inventory (BDI) score were observed. The endometrial thickness, typing, and endometrial blood flow resistance index (Rl) on the day of injecting HCG, the number of retrieved oocytes, the rate of high quality oo-cytes, the fertilization rate, the rate of high quality embryos, and the clinical pregnancy rate were respectively compared between the two groups. Results The scores of SDGDS, SAS, and BDI were improved more obviously in Group A than in Group B, showing statistical difference (P0. 05). The proportion of type A en-dometrium was 74. 5% (38/51 cases) in Group A and 45. 7% (21/46 cases) in Group B, showing statistical differ-ence between the two groups (P0.05). The rate of high quality oocyte, the rate of high quality embryos, and the clinical pregnancy rate were all improved more significantly in Group A than in Group B, showing statistical difference between the two groups (P < 0. 05). Conclusions Acupuncture combined CM-MTSSG could obviously alleviate unfavorable emotions as anxiety and depression in patients with IVF

    To assess the risk of heavy metal contamination of homoeopathic mother tinctures, 9 plant species and 1 fungus used in the manufacture of homoeopathic medicaments were investigated. Mother tinctures were prepared according to the manufacturing procedures described in the European Pharmacopoeia. The original herbal drug and the material processed during production were analysed for their cadmium (Cd), lead (Pb) and mercury (Hg) content. The plant components were harvested from 2 sites contaminated by different heavy metal exposure pathways and compared with reference material from Deutsche Homöopathie-Union (DHU). It was confirmed that in all cases a significant depletion of all heavy metals studied occurred during manufacture of the mother tincture, regardless of the starting material used. In all cases, most of the heavy metal content was retained in the press cake; low levels only were detected in the mother tincture. None of the mother tinctures of plant origin exceeded the required limits, not even those of plant starting materials originating from highly contaminated sites. Substantial heavy metal concentrations could only be detected in the mother tincture of the fungus Amanita muscaria, calculated from the dry weight of the starting material. According to the results obtained, a risk-based approach to heavy metal assessment is suggested where permanent control is focused on the heavy metals accumulating in organisms such as fungi.

    In the present paper, the authors make a bibliometrics study on clinical indications of acupuncture therapy based on the published foreign articles about acupuncture clinical trials collected from PubMed database and Excerpta Medica database (EMbase). In 1996, 64 acupuncture indications were declared by WHO in Milan conference. But in recent 15 years, clinical trials have been conducted extensively in the foreign countries. Till now, 77 new indications for acupuncture therapy have been found in the foreign journals. The authors recommended that 29 indications (knee osteoarthritis, critique age problems, muscular fasciae ache, anxiety, etc.) should be added to the first class, 4 indications (irritable bowel syndrome, malposition, backache, simple obesity) should be upgraded from the second class to the first class, and the other 3 indications (childbirth pain, male and female barren) should be upgraded from the third class to the first class due to their application frequency in clinical trials. Increase of clinical indications reflects extensive application of acupuncture therapy and may help providing a better service for people's health.

    Full Text Available Ayurvedic literature introduced several substitutes for the herbs which are either not available or which are not accessible for various reasons. On review of more than 35 texts and their commentaries it is found that there are more than 350 substitutes in the Ayurvedic texts from ancient to modern times. Kustha is known to therapeutics since Vedic period (2000 BC. Puskaramula and Erandamula were introduced to Ayurvedic Materia Medica by Agnivesa (500 BC. While mentioning the substitutes of Pushkaramula, Yogaratnakara quoted Kushta and Erandamula as the substitutes. Earlier author studied the pharmacognostical similarities between the three plants. Therefore, in the present study it iss decided to conduct a comparative study using the root powders of these three herbs in subjects (n=90 suffering with Tamaka Swasa (Bronchial Asthma divided into three groups. The results are suggestive that all the trial herbs have comparable therapeutic benefits in the subjects of Tamaka Swasa. While Kustha and Puskaramula have chemical as well as therapeutic similarity, Erandamula and pushkaramula shared only therapeutic similarity though chemically dissimilar. Thiss paper emphasizes the need for the identification of cost effective substitutes basing on the text in place of endangered or extinct medicinal plants.

    Full Text Available Responses to angiotensin II (Ang II were investigated in anaesthetised CD1 mice. Injections of Ang II caused dose-related increases in systemic arterial pressure that were antagonised by candesartan. Responses to Ang II were not altered by PD 123319. At the lowest dose studied (20 µg/kg i.v., the inhibitory effects of candesartan were competitive, whereas at the highest dose (100 µg/kg i.v., the dose-response curve for Ang II was shifted to the right in a non-parallel manner. The inhibitory effects of candesartan were selective and were similar in animals pretreated with enalaprilat to reduce endogenous Ang II production. Pressor responses to Ang II were not altered by propranolol, phentolamine or atropine, but were enhanced by hexamethonium. Increases in total peripheral resistance were inhibited by the AT1-receptor antagonist (ARB but were not altered by AT2-receptor, alpha- or beta-receptor antagonists. These results suggest that pressor responses to Ang II are mediated by AT 1-receptors, are buffered by the baroreceptors, are not modulated by effects on AT2receptors, and that activation of the sympathetic nervous system plays little role in mediating rapid haemodynamic responses to the peptide in anaesthetised mice.

    In conclusion, an animal model, miming the chronic contamination of the populations exposed to the uranium, was used for the first time to show that the chronic ingestion of a weak dose of depleted uranium can affect the level of active vitamin D without modifying the mineral homeostasis. This study shows that this radionuclide can lead molecular modifications of the CYPs and the nuclear receivers involved in the metabolism of the vitamin D not only at the level of the liver and kidney but also at the level of the independent metabolism in the brain. The deficiency in vitamin D can provoke osseous diseases such as the rickets at the child and the osteomalacia at the adult. The three categories of population the most exposed to this deficiency are the infants, the pregnant women and the old persons. Strong prevalence of the vitamin D deficiency associated with a chronic exposure to uranium could lead to osseous disorders. To verify this hypothesis, it will be necessary secondly to realize this study on individuals animal models predisposed to the rickets or to the osteomalacia. (N.C.)

    Introduction Root canal treatment is incomplete without usage of intra canal medicaments. They help in the reduction of bacterial count and its by-products, making canals clean and decreasing postoperative pains. Aim The aim of this study was to evaluate and compare the antimicrobial activity of triple antibiotic paste, Moxifloxacin, calcium hydroxide and 2% Chlorhexidine (CHX) gel in elimination of Enterococcous faecalis (E. faecalis). Materials and Methods Seventy-five root blocks were obtained from extracted single rooted human teeth. The canal diameter was increased using Gates- Glidden drill up to size 3 and then contaminated with E. faecalis for 21 days. The contaminated samples were then divided into following 5 groups. Group 1: Saline (negative group), Group 2: Calcium hydroxide Ca(OH)2, Group 3: 2% CHX gel, Group 4: Triple Antibiotic Paste (TAP) (50 μg – metronidazole of 400 mg, 50 μg – minocycline of 100 mg, 50 μg – ciprofloxacin of 100 mg) and Group 5: Moxifloxacin (50 μg – moxifloxacin of 400 mg). Dentin debris was obtained at the end of first, 7th, and 10th day using Gates Glidden drill sizes 4 and 5. The bacterial load was assessed by counting the number of Colony Forming Units (CFUs). The data were analyzed with the ANOVA and Post-Hoc tests to assess the differences in antibacterial efficacy between groups (p=<0.001). Results A 2% CHX gel alone completely inhibited the growth of E. faecalis after one, seven and 10 days. The 2% CHX gel was the most effective medicament against E. faecalis, as it showed significant differences with normal saline, calcium hydroxide, Moxifloxacin or triple antibiotic paste at all time intervals. The triple antibiotic paste group showed a moderate antibacterial effect as its difference with all group was significantly better at all days. Moxifloxacin was more effective than calcium hydroxide on 7th and 10th day. Conclusion Best antimicrobial efficacy was shown by 2% CHX gel. Moxifloxacin was equally efficient

    during acoustic and visual stimulation. The aim of this study was to investigate the prefronto-parietal network in elderly schizophrenia patients using the same paradigm. Additionally, we hypothesized favourable effects on brain activation by the atypical antipsychotic clozapine compared to typical neuroleptics. METHODS: We investigated 18 elderly, chronic schizophrenia patients and 21 elderly healthy controls. Nine schizophrenia patients had been medicated with clozapine and 9 had been receiving typical neuroleptics over decades. In addition to assessments with psychopathological and neuropsychological rating scales we used an acoustic and visual stimulation paradigm in a 1.5 Tesla MRI scanner to investigate BOLD-response in different brain areas. RESULTS: Compared to healthy controls schizophrenia patients showed decreased brain activation in the prefrontal and parietal cortex as well as medial anterior cingulate gyrus compared to healthy controls. In these regions, patients medicated with clozapine showed increased BOLD-response compared to patients treated with typical neuroleptics. DISCUSSION: Our study confirmed prefronto-parietal network disturbances in elderly schizophrenia patients thus pointing to the preservation of brain activation deficits and the influence of neurodevelopmental disturbances in chronic schizophrenia until old-age. CONCLUSION: The atypical antipsychotic clozapine seems to facilitate brain activation even in elderly, chronic schizophrenia patients.

    The present study was designed to provide preliminary information on the potential impact of metabolic drug-drug interaction on the effectiveness of doping control strategies currently followed by the anti-doping laboratories to detect the intake of banned agents. In vitro assays based on the use of human liver microsomes and recombinant CYP isoforms were designed and performed to characterize the phase I metabolic profile of the prohibited agent toremifene, selected as a prototype drug of the class of selective oestrogen receptor modulators, both in the absence and in the presence of medicaments (fluconazole, ketoconazole, itraconazole, miconazole, cimetidine, ranitidine, fluoxetine, paroxetine, nefazodone) not included in the World Anti-Doping Agency list of prohibited substances and methods and frequently administered to athletes. The results show that the in vitro model developed in this study was adequate to simulate the in vivo metabolism of toremifene, confirming the results obtained in previous studies. Furthermore, our data also show that ketoconazole, itraconazole, miconazole and nefazodone cause a marked modification in the production of the metabolic products (i.e. hydroxylated and carboxylated metabolites) normally selected by the anti-doping laboratories as target analytes to detect toremifene intake; moderate variations were registered in the presence of fluconazole, paroxetine and fluoxetine; while no significant modifications were measured in the presence of ranitidine and cimetidine. This evidence imposes that the potential effect of drug-drug interactions is duly taken into account in anti-doping analysis, also for a broader significance of the analytical results.

    Full Text Available Background: The aim of this ex vivo study was to compare the antimicrobial effect of triantibiotic paste, 0.2% chlorhexidine gel, Propolis and Aloe vera on Enterococcus faecalis in deep dentin. Materials and Methods: Ninety fresh extracted single-rooted teeth were used in a dentin block model. Seventy-five teeth were infected with E. faecalis and divided into four experimental groups (n = 15. Experimental groups were treated with triantibiotic mixture with distilled water, 0.2% chlorhexidine gel, 70% ethanol + Propolis and Aloe vera. Fifteen teeth treated with distilled water as the positive control and 15 samples, free of bacterial contamination, were considered as the negative control. Gates-Glidden drill #4 was used for removal of surface dentin and Gates-Glidden drill #5 was used to collect samples of deep dentin. The samples were prepared and colony-forming units were counted. Data were analyzed by one-way ANOVA and post hoc Tukey tests. Statistical significance was defined at P 0.05. Aloe vera had antibacterial effects on E. faecalis, but in comparison with other medicaments, it was less effective (P < 0.05. Conclusion: This experimental study showed that triantibiotic mixture, 0.2% chlorhexidine gel, Propolis and Aleo vera were relatively effective against E. faecalis. All the intracanal medicements had similar effects on E. faecalis in deep dentin except for Aloe vera.

    A novel method for the determination of vitamin C(Vc) is proposed in this article. After the reaction with Folin-Ciocalteau reagent at ambient temperature, Vc solution was scanned at 750-1100 nm, and its first-order derivative spectrum were obtained from the original spectrum. The values of derivative selected at 995 nm were used for determination. It was proved that Vc could quickly react with Folin-Ciocalteau reagent within 5 min and the product was quite stable for a long time. The conditions required for this method is not very complicated, its precision and accuracy are similar to those of the iodometric titration described in Chinese Pharmacopoeia, and the limit of detection is 0.312μg/mL. The determination of the results of vitamin C tablet, pill, and injection demonstrates that this method has wide pharmaceutical applications.

El objetivo de nuestro estudio es estudiar la prevalencia de consumo de tabaco entre las médicas y enfermeras de la Comunidad de Madrid, así como sus actitudes y conocimientos respecto al tabaquismo. MÉTODOS: Se ha realizado un estudio descriptivo transversal entre las mujeres profesionales de la salud (médicas y enfermeras de la Comunidad de Madrid, mediante una encuesta sobre hábito tabáquico, en un muestreo polietápico por conglomerados. RESULTADOS: Se han estudiado 1.235 profesionales ( 435 médicas y 800 enfermeras. El 43,07% del total son fumadoras, siendo el tabaquismo mayor en las enfermeras (47,62% que en las médicas (34,71%, y entre quienes trabajan en atención especializada (46,68% que entre las que lo hacen en atención primaria (35,29%. El tabaquismo fue diferente en ambas profesiones.según la edad En las médicas era menor tabaquismo en las edades entre 20 y 30 años (22,88%, y en las enfermeras este grupo de edad era el que tenia un mayor porcentaje de fumadoras (52,38%. Eran exfumadoras el 18,3% del total de las encuestadas, y el 64,65% de las que fumaban señalaron que habían intentado dejarlo. Un 2,93% fumaban delante de los/as pacientes, y un 14,94% pensaban que debía permitirse fumar en las salas de espera. El 27,46% creían que estaba permitido fumar en su area de trabajo, y el 90,64% señaló que se fumaba habitualmente en las salas de uso común del personal sanitario, y un 30,37% respondió que existía un lugar especifico para fumar en el centro de trabajo. CONCLUSIONES: La prevalencia de tabaquismo entre las profesionales de la salud, médicas y enfermeras, de la Comunidad de Madrid, es elevada, superior a la de la población general de igual edad y genero. El tabaquismo entre las enfermeras es más frecuente que entre las médicas, y en los hospitales que en Atención Primaria, y entre las enfermeras en el grupo más joven, lo que es muy preocupante.

    Full Text Available El proceso de educación médica continua se favorecería si los encargados de las actividades consideraran la calidad académica de los docentes, ya que es importante tener en cuenta la comprensión, intereses, motivaciones y actitudes de los médicos y los aspectos del proceso educativo en sí, como las teorías y metodologías de enseñanza y estrategias de evaluación de los aprendizajes que les permitieran cumplir con sus objetivos pedagógicos. Es posible identificar elementos del proceso educativo que deben incluirse en los programas de Educación Médica Continua, tales como: definir objetivos de aprendizaje, técnicas metodológicas y de evaluación de los aprendizajes, tiempo requerido para abarcar los contenidos y definir el perfil idóneo de los asistentes y del docente que participa en este tipo de programas, siempre en aras de la mejora del proceso enseñanza-aprendizaje. Tanto los encargados como los docentes de estas actividades deben estar calificados para realizar los procesos que hacen posible el desarrollo de la acción educativa: análisis de necesidades, programación, diseño y elaboración de metodologías, ejecución de técnicas, evaluación y seguimiento de los aprendizajes. Además, los encargados deben estar conscientes de que en el proceso enseñanza-aprendizaje intervienen el alumno, el docente y una situación de aprendizaje y en este sentido esta tríada se convierte en la protagonista sujeta a evaluación. El proceso de capacitación a encargados debe orientarse, entre otros, a dotarlos de habilidades para mejorar la calidad del proceso enseñanza-aprendizaje, como la comunicación eficiente, la actitud crítica e investigativa y desarrollar las habilidades de evaluación de los aprendizajes.The process of continued medical education would be favored if the people in charge of this activities consider the academic quality of the teachers, because is important have in mind the comprehension, interests, motivations and attitudes of the doctors and the aspects of the educative process, such as the theories and teaching and evaluation methods that allow them to accomplish their pedagogical objectives. It is possible to identify elements of the educative projects that need to be included in the programs of Continued Medical Education, for instance: define learning objectives, methodological techniques and evaluation techniques of the acquired knowledge, the required time to complete the contents and define the proper profile of the assistants and of the teacher who participates in this types of programs, always trying to improve the learning / teaching process. Both have to be qualified - the people in charge and the teachers of these activities - to carry out the processes that make the development of the educational action possible: analysis of the needs, programming, design and elaboration of methodologies, technique execution, evaluation, and follow up of the acquired knowledge. Moreover, the people in charge must be aware that the learning - teaching process involves the student, the teacher, and a learning situation, and in this way this triad becomes the subject of evaluation. The capacitating process to the people in charge must be oriented, among others, to empower their abilities to improve the quality of the teaching - learning process, enhance efficient communication, increase critical and investigative attitudes, and develop the evaluation abilities of the acquired knowledge.

Los caciques no disimulan su admiración ante la valentía de Rosas, quien los visita sin alarma ante el contagio y los estimula a vacunarse para eliminar el temible mal. Un número estimado en más de cien indios acepta, entonces, inmunizarse, colocándose, según el testimonio de Parish, la «vacuna a indígenas ». Buenos Aires, 1833. Francisco X. Muñiz, médico de la campaña bonaerense, inicia las investigaciones con las que diez años después se logra el redescubrimiento del cow pox, es decir, la viruela vacuna, llamada por Sarmiento «la vacuna indígena».

    Endodontic therapy is indicated for cases of traumatic tooth dislocation associated with pulp necrosis and/or inflammatory resorption. Here we describe the management of a maxillary left lateral permanent incisor that suffered lateral luxation, leading to pulp necrosis and root resorption, in a 13-year-old boy. The traumatized tooth was treated successfully by intracanal medication with calcium hydroxide, 2% chlorhexidine gel and zinc oxide for 12 months without any need to change the dressing, followed by conventional root canal filling. The postoperative course was uneventful and a stable clinical outcome was obtained with evidence of periapical lesion repair and stabilization of the resorption process.
