Atropa belladonna, commonly known as belladonna or deadly nightshade, ranks among one of the most poisonous plants in Europe and other parts of the world. The plant contains tropane alkaloids including atropine, scopolamine, and hyoscyamine, which are used as anticholinergics in Food and Drug Administration (FDA) approved drugs and homeopathic remedies. These alkaloids can be very toxic at high dose. The FDA has recently reported that Hyland's baby teething tablets contain inconsistent amounts of Atropa belladonna that may have adverse effects on the nervous system and cause death in children, thus recalled the product in 2017. A greater understanding of the neurotoxicity of Atropa belladonna and its modification of genetic polymorphisms in the nervous system is critical in order to develop better treatment strategies, therapies, regulations, education of at-risk populations, and a more cohesive paradigm for future research. This review offers an integrated view of the homeopathy and neurotoxicity of Atropa belladonna in children, adults, and animal models as well as its implications to neurological disorders. Particular attention is dedicated to the pharmaco/toxicodynamics, pharmaco/toxicokinetics, pathophysiology, epidemiological cases, and animal studies associated with the effects of Atropa belladonna on the nervous system. Additionally, we discuss the influence of active tropane alkaloids in Atropa belladonna and other similar plants on FDA-approved therapeutic drugs for treatment of neurological disorders.

Atropa belladonna is a poisonous plant also called deadly nightshade. Its roots, leaves and fruits contain alkaloids: atropine, hyocyamine and scopolamine. The risk of poisoning in children is important because of possible confusion with other berries. Atropa belladonna acute intoxication is a severe condition, it's should be considered in the presence of anti-cholinergic toxidrome, the differential diagnosis include other plants or psychoactive drugs containing atropine. The treatment is mainly symptomatic including gastrointestinal decontamination with activated charcoal. In severe cases, physostigmine can be used as an antidote. We report the case of 11 year old girl with Atropa belladonna poisoning which was administrated in a therapeutic purpose as a remedy to jaundice. The child presented essentially a central anti-cholinergic syndrome. She was admitted in the intensive care unit, the progression was favorable with symptomatic treatment.

Atropa Belladonna poisoning may lead to anticholinergic syndrome. Ingestion of high amounts of the plant may cause lethargy, coma, and even a serious clinical picture leading to death. In this case report, we aimed to present a case with anticholinergic syndrome that developed after ingestion of the fruit called “Deadly Nightshade” in our country. PMID:27366377

Plant intoxications account for 5% of all intoxication cases according to French anti-poison centers. We report an uncommon case of intoxication with deadly nightshade (Atropa belladonna) in a 2-year-old child. The child presented at the ER with an atropinic syndrome, both central and peripheral, after ingestion of wild berries a few hours before. The fruit and leaves brought in by the mother allowed the anti-poison center to identify belladonna, in agreement with clinical findings. The child was kept in the intensive care unit for 48 h and progression was favorable with symptomatic treatment. Copyright © 2010 Elsevier Masson SAS. All rights reserved.

Leaf tissues of Atropa belladonna were transformed by Sdrac2, a Rac GTPase gene, that is isolated from Scoparia dulcis, and the change in atropine concentration of the transformants was examined. Re-differentiated A. belladonna overexpressing Sdrac2 accumulated considerable concentration of atropine in the leaf tissues, whereas the leaves of plants transformed by an empty vector accumulated only a very low concentration of the compound. A. belladonna transformed by CASdrac2, a modified Sdrac2 of which translate was expected to bind guanosine triphosphate (GTP) permanently, accumulated very high concentrations of atropine (approximately 2.4-fold excess to those found in the wild-type plant in its natural habitat). In sharp contrast, the atropine concentration in transformed A. belladonna prepared with negatively modified Sdrac2, DNSdrac2, expected to bind guanosine diphosphate instead of GTP, was very low. These results suggested that Rac GTPases play an important role in the regulation of secondary metabolism in plant cells and that overexpression of the gene(s) may be capable of enhancing the production of natural products accumulated in higher plant cells.

Polyploid hybrids represent a rich natural resource to study molecular evolution of plant genes and genomes. Here, we applied a combination of karyological and molecular methods to investigate chromosomal structure, molecular organization and evolution of ribosomal DNA (rDNA) in nightshade, Atropa belladonna (fam. Solanaceae), one of the oldest known allohexaploids among flowering plants. Because of their abundance and specific molecular organization (evolutionarily conserved coding regions linked to variable intergenic spacers, IGS), 45S and 5S rDNA are widely used in plant taxonomic and evolutionary studies. Molecular cloning and nucleotide sequencing of A. belladonna 45S rDNA repeats revealed a general structure characteristic of other Solanaceae species, and a very high sequence similarity of two length variants, with the only difference in number of short IGS subrepeats. These results combined with the detection of three pairs of 45S rDNA loci on separate chromosomes, presumably inherited from both tetraploid and diploid ancestor species, example intensive sequence homogenization that led to substitution/elimination of rDNA repeats of one parent. Chromosome silver-staining revealed that only four out of six 45S rDNA sites are frequently transcriptionally active, demonstrating nucleolar dominance. For 5S rDNA, three size variants of repeats were detected, with the major class represented by repeats containing all functional IGS elements required for transcription, the intermediate size repeats containing partially deleted IGS sequences, and the short 5S repeats containing severe defects both in the IGS and coding sequences. While shorter variants demonstrate increased rate of based substitution, probably in their transition into pseudogenes, the functional 5S rDNA variants are nearly identical at the sequence level, pointing to their origin from a single parental species. Localization of the 5S rDNA genes on two chromosome pairs further supports uniparental

Regenerated plants were obtained through callus organogenesis after gamma ray treatment with 1 to 9 Krad doses. Vigorous shoots were regenerated on MS (1962) medium supplemented with 2 mg/l 6-benzylaminopurine. Shoot growth was inhibited with increasing irradiation doses. At 2 Krad dose root Primordia were observed after 18 days while 32 days were necessary to produce roots at 7-9 Krad. As compared to the control, the survival percent during acclimatization was 80 to 85% at 2-3 Krad, 65-70% at 4-6 Krad and 60-62% at 7-9 Krad. Approximately 330 plants were transferred to field conditions. Morphological and biochemical parameters were measured and the data were statistically processed. Plant height was negatively influenced by higher doses of irradiation. A chlorophyll deficient plant arose from the 6 Krad treatment which showed a different pattern of isoperoxidase and isoesterase as compared to the control. A yellow-flower mutant was obtained from the 3 Krad treatment and is assumed to be Atropa belladonna var. Flava Pater. (author)

Atropa belladonna is one of the most important plant sources for producing pharmaceutical tropane alkaloids (TAs). T1 progeny of transgenic A. belladonna, in which putrescine N-methyltransferase (EC. 18.104.22.168) from Nicotiana tabacum (NtPMT) and hyoscyamine 6β-hydroxylase (EC. 22.214.171.124) from Hyoscyamus niger (HnH6H) were overexpressed, were established to investigate TA biosynthesis and distribution in ripe fruits, leaves, stems, primary roots and secondary roots under field conditions. Both NtPMT and HnH6H were detected at the transcriptional level in transgenic plants, whereas they were not detected in wild-type plants. The transgenes did not influence the root-specific expression patterns of endogenous TA biosynthetic genes in A. belladonna. All four endogenous TA biosynthetic genes (AbPMT, AbTRI, AbCYP80F1 and AbH6H) had the highest/exclusive expression levels in secondary roots, suggesting that TAs were mainly synthesized in secondary roots. T1 progeny of transgenic A. belladonna showed an impressive scopolamine-rich chemotype that greatly improved the pharmaceutical value of A. belladonna. The higher efficiency of hyoscyamine conversion was found in aerial than in underground parts. In aerial parts of transgenic plants, hyoscyamine was totally converted to downstream alkaloids, especially scopolamine. Hyoscyamine, anisodamine and scopolamine were detected in underground parts, but scopolamine and anisodamine were more abundant than hyoscyamine. The exclusively higher levels of anisodamine in roots suggested that it might be difficult for its translocation from root to aerial organs. T1 progeny of transgenic A. belladonna, which produces scopolamine at very high levels (2.94-5.13 mg g(-1)) in field conditions, can provide more valuable plant materials for scopolamine production.

Multiple shoot cultures were established from shoot tip and axillary meristem of the plant Atropa belladonna. The cultures were initially raised on agar medium and subsequently maintained on liquid medium of Murashige and Skoog (1962) supplemented with BA. These cultures were subjected to different doses of -y-irradiation. Recovery from the radiation effects was observed in tissues subjected to 29 Gy during four successive passages. Plant growth regulators influenced the growth and morphogenetic events of the tissues. The precursors of tropane alkaloids marginally increased the alkaloid synthesis during the stationary phase of growth. Shoot cultures, established from different field grown plants varying in alkaloid content, were morphologically similar and did not exhibit the parental characteristics with respect to alkaloid formation

Due to random exploitation from natural resources, an efficient regeneration system of medicinally important but rare plant species, Atropa acuminata for conservation was inevitable. Leaf explants were incubated on MS medium with different level of various plant growth regulators (PGRs) alone and in combination for callus induction and induced organogenesis. After 4 weeks of culture, callus induction was recorded with the highest frequency with 1.0 mg/l thidiazuron (TDZ) supplement. After 5 weeks of subsequent sub-culturing, optimum shoot induction frequency of 89% was achieved with 1.0 mg/l TDZ and 1.0 mg/l a-naphthaleneacetic acid (NAA) supplement. Highest number of shoots/explant (8.2) were recorded on MS medium with 2.0 mg/l 6-benzyladenine (BA)+1.0 mg/l NAA supplement. Shoots in elongation medium was recorded 5.8 cm long in two medium i.e., 1.0 mg/l TDZ supplement and 1.0 mg/l TDZ+1.0 mg/l NAA supplement. Successful In vitro rooting was induced on MS medium with all applied level of indole butyric acid (IBA). The regenerated shoots with well developed roots were successfully acclimatized in sterilized soil and transferred to greenhouse conditions. Furthermore higher activity for detoxifying DPPH free radical was shown by regenerated shoots in this medicinally important plant species. (author)

After vaginal surgery, oral and parenteral narcotics are used commonly for pain relief, and their use may exacerbate the incidence of sedation, nausea, and vomiting, which ultimately delays convalescence. Previous studies have demonstrated that rectal analgesia after surgery results in lower pain scores and less intravenous morphine consumption. Belladonna and opium rectal suppositories may be used to relieve pain and minimize side effects; however, their efficacy has not been confirmed. We aimed to evaluate the use of belladonna and opium suppositories for pain reduction in vaginal surgery. A prospective, randomized, double-blind, placebo-controlled trial that used belladonna and opium suppositories after inpatient or outpatient vaginal surgery was conducted. Vaginal surgery was defined as (1) vaginal hysterectomy with uterosacral ligament suspension or (2) posthysterectomy prolapse repair that included uterosacral ligament suspension and/or colporrhaphy. Belladonna and opium 16A (16.2/60 mg) or placebo suppositories were administered rectally immediately after surgery and every 8 hours for a total of 3 doses. Patient-reported pain data were collected with the use of a visual analog scale (at 2, 4, 12, and 20 hours postoperatively. Opiate use was measured and converted into parenteral morphine equivalents. The primary outcome was pain, and secondary outcomes included pain medication, antiemetic medication, and a quality of recovery questionnaire. Adverse effects were surveyed at 24 hours and 7 days. Concomitant procedures for urinary incontinence or pelvic organ prolapse did not preclude enrollment. Ninety women were randomly assigned consecutively at a single institution under the care of a fellowship-trained surgeon group. Demographics did not differ among the groups with mean age of 55 years, procedure time of 97 minutes, and prolapse at 51%. Postoperative pain scores were equivalent among both groups at each time interval. The belladonna and opium group used a

Two prospective trials have demonstrated prophylactic antimuscarinics following prostatectomy reduce pain from bladder spasms. Our practice adopted the routine administration of prophylactic belladonna and opium (B&O) suppositories to patients undergoing robotic assisted laparoscopic radical prostatectomy (RALP). The aim of this study is to determine if this change in clinical practice was associated with improvement of postoperative outcomes. The medical records of 202 patients that underwent RALP surgery who were or were not administered prophylactic B&O suppositories in the immediate postoperative period were abstracted for duration of anesthesia recovery, pain and analgesic use. Patient and surgical characteristics between groups were similar except B&O group were slightly older (p = 0.04) and administered less opioid analgesics (p = 0.05). There was no difference between groups in the duration of phase I recovery from anesthesia (p = 0.96). Multivariable adjustments for age, body mass index, American Society of Anesthesiologists physical status, and surgical duration were made, and again it was found that suppository administration had no association with phase I recovery times (p = 0.94). The use of antimuscarinic medication for bladder spams in the B&O group was less during phase I recovery (p suppositories at the immediate conclusion of RALP surgery was not associated with improvements of the postoperative course.

A novel 15 kDa antifungal protein amaryllin has been crystallized using 30% PEG 8000 as the precipitating agent. The crystals belong to orthorhombic space group I or I2 1 2 1 2 1 with cell dimensions, a = 48.6, b = 61.9 and c = 79.6–Å. A novel antifungal protein, amaryllin, has been isolated from the underground bulbs of Amaryllis belladonna, purified to homogeneity and crystallized. The protein was extracted using ammonium sulfate fractionation. The purified protein samples indicated a molecular weight of 15 kDa on SDS–PAGE. The protein showed antifungal activity against Aspergillus flavus and Fusarium oxysporum. The N-terminal sequence of the first 15 amino-acid residues was determined using Edman degradation and did not show significant sequence identity to any known protein. The protein was crystallized using the hanging-drop vapour-diffusion method with 30% PEG 8000 as precipitating agent. The crystals diffracted to 2.7 Å resolution and belonged to the orthorhombic space group I222 or I2 1 2 1 2 1 , with unit-cell parameters a = 48.6, b = 61.9, c = 79.6 Å.

To investigate whether the use of a belladonna and opium (B&O) rectal suppository administered immediately before ureteroscopy (URS) and stent placement could reduce stent-related discomfort. A randomized, double-blinded, placebo-controlled study was performed from August 2013 to December 2014. Seventy-one subjects were enrolled and randomized to receive a B&O (15 mg/30 mg) or a placebo suppository after induction of general anesthesia immediately before URS and stent placement. Baseline urinary symptoms were assessed using the American Urological Association Symptom Score (AUASS). The Ureteral Stent Symptom Questionnaire and AUASS were completed on postoperative days (POD) 1, 3, and after stent removal. Analgesic use intraoperatively, in the recovery unit, and at home was recorded. Of the 71 subjects, 65 had treatment for ureteral (41%) and renal (61%) calculi, 4 for renal urothelial carcinoma, and 2 were excluded for no stent placed. By POD3, the B&O group reported a higher mean global quality of life (QOL) score (P = .04), a better mean quality of work score (P = .05), and less pain with urination (P = .03). The B&O group reported an improved AUASS QOL when comparing POD1 with post-stent removal (P = .04). There was no difference in analgesic use among groups (P = .67). There were no episodes of urinary retention. Age was associated with unplanned emergency visits (P <.00) and "high-pain" measure (P = .02) CONCLUSION: B&O suppository administered preoperatively improved QOL measures and reduced urinary-related pain after URS with stent. Younger age was associated with severe stent pain and unplanned hospital visits. Copyright © 2016 Elsevier Inc. All rights reserved.
Full Text Available Background & Aim:A new sustainable tissue-based system is presented by plant hairy roots, preserving all of the several specialized types of cell with critical roles in allowing bioactive secondary molecules to be synthesized more consistently as usual. The system is also essential for studying the production of alkaloid in culture. Experimental: The Atropa komarovii leaves were wounded and infected with soil gram-negative bacterium Agrobacterium rhizogenes ATCC15834. After three weeks, the transformation roots and control roots without infection, appeared, and for confirming that T-DNA Ri plasmid fragments were transformed and integrated to plant genome, the rolB gene region, was amplified using PCR. HPLC method was then used for assaying how two tropane alkaloids such as atropine (hyosciamine and scopolamine (hyoscine were produced in hairy roots,control roots, leaves and roots of plantlet. Results: The data indicated that diagnostic 500bp rol B product amplification was exhibited to be present by all the transformed hairy roots. Scopolamine content in hairy roots was considerably greater than that in control roots but greatest (Hyoscyamine atropine content was observed in control roots. Analysis of DW, FW and root length showed that fresh and dry root weight increased in hairy roots compared with that in non transformed root. Recommended applications/industries: The present study demonstrated that secondary metabolite production using medicinal plants concerns many researchers worldwide today and hairy root culture is a useful method for producing tropane alkaloids in solanaceae.

The size of complete chloroplast genomes and LSC and SSC regions of three species of Solanum is comparatively smaller than that of any other species studied till date (exception: SSC region of A. belladonna. AT content of coding regions was found to be less than noncoding regions. A duplicate copy of trnH gene in C. annuum and two alternative tRNA genes for proline in D. stramonium were observed for the first time in this analysis. Further, homology search revealed the presence of rps19 pseudogene and infA genes in A. belladonna and D. stramonium, a region identical to rps19 pseudogene in C. annum and orthologues of sprA gene in another six species. Among the eighteen intron-containing genes, 3 genes have two introns and 15 genes have one intron. The longest insertion was found in accD gene in C. annuum. Phylogenetic analysis using concatenated protein coding sequences gave two clades, one for Nicotiana species and another for Solanum, Capsicum, Atropa, and Datura.

Gamma rays and/or alkylant agents have been applied on callus tissue, young regenerants and cell suspension in order to establish their effect on morphogenesis, regeneration ability and biosynthetic potential. Growth dynamics, morpho-anatomic variables, secondary metabolite production, cell cytogenetics, enzyme specific activities, isoperoxidase and isoesterase patterns were analyzed in relation to the morphogenetic response of Atropa belladonna, Datura innoxia, Lavandula angustifolia, Chamomilla recutita, Digitalis lanata and Vinca minor tissue cultures. The effects of gamma-ray doses varied from one species to another; 10 to 20 Gy were generally able to stimulate growth and plant regeneration (via organogenesis and somatic embryogenesis), while 10 to 50 Gy enhanced secondary metabolite biosynthesis both in callus and cell suspension culture. Semnificative increase of secondary metabolite production was obtained when treatments with EMS (0.1-0.2%) have been applied to young regenerants. Many differences in biological features and biochemical behaviour were registered 20 days and one year, respectively, after treatment. (author)

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

Full Text Available The availability of chloroplast genome (cpDNA sequences of Atropa belladonna, Nicotiana sylvestris, N.tabacum, N. tomentosiformis, Solanum bulbocastanum, S. lycopersicum and S. tuberosum, which are Solanaceae species,allowed us to analyze the organization of cpSSRs in their genic and intergenic regions. In general, the number of cpSSRs incpDNA ranged from 161 in S. tuberosum to 226 in N. tabacum, and the number of intergenic cpSSRs was higher than geniccpSSRs. The mononucleotide repeats were the most frequent in studied species, but we also identified di-, tri-, tetra-, pentaandhexanucleotide repeats. Multiple alignments of all cpSSRs sequences from Solanaceae species made the identification ofnucleotide variability possible and the phylogeny was estimated by maximum parsimony. Our study showed that the plastomedatabase can be exploited for phylogenetic analysis and biotechnological approaches.
Full Text Available Melliferous plant species in the forests near Blace (South Serbia were investigated in order to estimate the significance, contribution, quality and ecological characteristics of representatives of the apiflora as potential nectar and pollen sources, the elements of bee pasturage. The significance of melliferous plants was determined on the basis of nectar and pollen production intensity, as well as by following blooming periods. According to adaptations to moisture, light, and temperature, melliferous species can be relegated to eight groups and six subgroups. Out of the total number of melliferous species in the investigated area (223, the forest apiflora accounted for 82 species (36,77%. The species with highest nectar and/or pollen production are: Alnus glutinosa, Corylus avellana, Paulownia tomentosa, Picea abies, Prunus tenella, Robinia pseudoacacia, species of the genera Salix, Tilia, and Campanula, Atropa bella-donna, Calamintha officinalis, Glechoma hederacea, Pulmonaria officinalis, Salvia glutinosa and Valeriana officinalis.

Sometimes even the consumption of small amounts causes poisoning with a broad extension: from mild, moderate to severe and with chronic or acute manifestations. Plant action is not similar. Taxus Buccata, Eupatorium spp. (E. rugosum, E. urticaefolium, E. ogeratoides are cardiotoxic plants, but, Eupatorium spp. also acts through depression of the central nervous system; Datura stramonium (Jimson weed, Solanum spp. (nightshades, Atropa belladonna (belladonna, are plants with cholinergic blocking; haemolytic anemia is caused by Pteridium aquilinum (Bracken fern and Equisetum (horsetail. The poisoning with cyanogenic principles occurs at Sorghum spp (Johnson grass, sudan grass; Elderberry consumption, Senecio spp. and Hypericum (St John’s wort induces liver toxicity. Plants containing alkaloids outside their toxicity also have teratogenic action: Lupinus spp., Nicotiana spp, Conium maculatum, Veratrum album. However, some of these plants can be used in certain cows’ treatments.

Desorption electrospray ionization (DESI) mass spectrometry is applied to the in situ detection of alkaloids in the tissue of poison hemlock (Conium maculatum), jimsonweed (Datura stramonium) and deadly nightshade (Atropa belladonna). The experiment is carried out by electrospraying micro-droplets of solvent onto native or freshly-cut plant tissue surfaces. No sample preparation is required and the mass spectra are recorded under ambient conditions, in times of a few seconds. The impact of the sprayed droplets on the surface produces gaseous ions from organic compounds originally present in the plant tissue. The effects of operating parameters, including the electrospray high voltage, heated capillary temperature, the solvent infusion rate and the carrier gas pressure on analytical performance are evaluated and optimized. Different types of plant material are analyzed including seeds, stems, leaves, roots and flowers. All the previously reported alkaloids have been detected in C. maculatum, while fifteen out of nineteen known alkaloids for D. stramonium and the principal alkaloids of A. belladonna were also identified. All identifications were confirmed by tandem mass spectrometry. Results obtained show similar mass spectra, number of alkaloids, and signal intensities to those obtained when extraction and separation processes are performed prior to mass spectrometric analysis. Evidence is provided that DESI ionization occurs by both a gas-phase ionization process and by a droplet pick-up mechanism. Quantitative precision of DESI is compared with conventional electrospray ionization mass spectrometry (after sample workup) and the RSD values for the same set of 25 dicotyledonous C. maculatum seeds (one half of each seed analyzed by ESI and the other by DESI) are 9.8% and 5.2%, respectively.

Caterpillars of the monarch butterfly, Danaus plexippus, feed on milkweed plants, Asclepias spp. (Apocynaceae), and sequester their toxic cardenolides aimed at deterring predators. Nevertheless, Chinese praying mantids, Tenodera sinensis, consume these caterpillars after removing the midgut ("gutting") including its plant content. In the present study, monarch caterpillars raised on A. curassavica, and those of the death's-head hawkmoth, Acherontia atropos, raised on Atropa belladonna containing atropine, were fed to mantids, Hierodula membranacea, which removed the gut of both species discarding about 59% of cardenolides and more than 90% of atropine, respectively. The ingestion of these compounds produced no apparent ill effects in the mantids and both were excreted with faeces. On the other hand, when mantids were fed with larvae of two moth species, Amata mogadorensis and Brahmaea certia, raised on non-poisonous host plants, the mantids showed the same gutting behaviour, thereby discarding indigestible plant material. As polar compounds, e.g. cardenolides and atropine, are not absorbed from the mantids midgut and do not pass the gut membrane, this enables the mantids to feed on toxic prey.

Despite good manufacturing practice and quality control, consumer products can become contaminated. In some cases, this can result in severe and life-threatening intoxication with potentially fatal consequences. A 27-year-old man and a 28-year-old pregnant woman presented to the Emergency Department with severe anticholinergic syndrome after using a marshmallow root (Althaea officinalis) herbal remedy, mixed into hot chocolate drink, to reduce symptoms of common cold. After a short stay in Intensive Care, the symptoms diminished and the patients could be released from hospital. The herbs were found to be contaminated with atropine, most probably derived from deadly nightshade (Atropa belladonna). Analyses of the contaminated product indicated that the patients were exposed to 20-200 mg atropine, while a dose of 2 mg is already considered mildly toxic. Consultation of the Dutch National Poisons Information Center resulted in rapid detection of the contamination; close collaboration with the Netherlands Food and Consumer Product Safety Authority and the manufacturer of the product allowed rapid identification of the source of contamination and facilitated the prevention of an epidemic.
Full Text Available Background: Some species from the Solanaceae family are still the cause of serious poisoning among youth in Slovenia. Usually intoxication is due to abuse of these plants to provoke hallucinations. There is still not enough data about the alkaloid content of these plants growing in Slovenia.Methods: Different plant samples were analyzed for the content of atropine and scopolamine with capillary electrophoresis after solid phase extraction of alkaloids. Plants were gathered from different areas of Slovenia between April and September 2004.Results: Results were compared and possible correlations between the alkaloid content and species, plant parts, growth conditions, and time of harvest were suggested. Atropine and scopolamine contents were assessed in deadly nightshade (Atropa belladonna L., thorn apple (Datura stramonium L., scopolia (Scopolia carniolica Jacq. and angel trumpet. The common name angel trumpet is used for Datura inoxia Mill. as well as for different Brugmansia Pers. species. The most intriguing results were the variable alkaloid content in various Brugmansia species and generally great differences in alkaloid content among various plants and their plant parts.Conclusions: All investigated plants have noticeable atropine and/or scopolamine content. The content is variable between various plants and their plant parts and therefore special care should be taken in cases of possible intoxication. It was shown that smaller or greater amounts of ingested drug can cause the same level of intoxication due to the variability in alkaloid content.

Plant-derived molecules (PDMs) are known to be a rich source of diverse scaffolds that could serve as the basis for rational drug design. Structured compilation of phytochemicals from traditional medicinal plants can facilitate prospection for novel PDMs and their analogs as therapeutic agents. Atropa belladonna, Catharanthus roseus, Heliotropium indicum, Picrorhiza kurroa and Podophyllum hexandrum are important Himalayan medicinal plants, reported to have immense therapeutic properties against various diseases. We present Phytochemica, a structured compilation of 963 PDMs from these plants, inclusive of their plant part source, chemical classification, IUPAC names, SMILES notations, physicochemical properties and 3-dimensional structures with associated references. Phytochemica is an exhaustive resource of natural molecules facilitating prospection for therapeutic molecules from medicinally important plants. It also offers refined search option to explore the neighbourhood of chemical space against ZINC database to identify analogs of natural molecules at user-defined cut-off. Availability of phytochemical structured dataset may enable their direct use in in silico drug discovery which will hasten the process of lead identification from natural products under proposed hypothesis, and may overcome urgent need for phytomedicines. Compilation and accessibility of indigenous phytochemicals and their derivatives can be a source of considerable advantage to research institutes as well as industries.

Full Text Available Studying explants affected by Agrobacterium rhizogenes shows that in addition to possible formation of hairy roots, it is likely that callogenesis can be induced in these tissues. The T-DNA region of A. rhizogenes codes enzymes that participate in biosynthesis of plants growth hormones. These hormones also affect callogenesis, hence, the formation of various calluses with different morphological properties are possible. It is very likely that the level of biosynthetic growth hormone, the plasmid carried by each bacteria strain, the position of T-DNA, and the level of gene expression contribute to this morphologic variation. In this study, the root explants of four species of the family Solanaceae namely Atropa belladonna, Datura metel, D. stramonium and Hyoscyamus niger were induced by using different strains of A. rhizogenes (A4, A7, AR15834, AR318, AR9402 and AR9543. Some of these explants entered callus phase and formed various calluses with different colors and shapes. Moreover, in some callus samples hairy roots were also appeared. These variations were probably caused by variations in the levels and ratios of auxin and cytokinine hormons after the induction. As shown in previous studies, the amount of secondary metabolites is reduced due to undifferentiated tissue produced in the callogenesis process.
Background Chloroplast genomes evolve slowly and many primers for PCR amplification and analysis of chloroplast sequences can be used across a wide array of genera. In some cases 'universal' primers have been designed for the purpose of working across species boundaries. However, the essential information on these primer sequences is scattered throughout the literature. Results A database is presented here which assembles published primer information for chloroplast DNA. Additional primers were designed to fill gaps where little or no primer information could be found. Amplicons are either the genes themselves (typically useful in studies of sequence variation in higher-order phylogeny) or they are spacers, introns, and intergenic regions (for studies of phylogeographic patterns within and among species). The current list of 'generic' primers consists of more than 700 sequences. Wherever possible, we give the locations of the primers in the thirteen fully sequenced chloroplast genomes (Nicotiana tabacum, Atropa belladonna, Spinacia oleracea, Arabidopsis thaliana, Populus trichocarpa, Oryza sativa, Pinus thunbergii, Marchantia polymorpha, Zea mays, Oenothera elata, Acorus calamus, Eucalyptus globulus, Medicago trunculata). Conclusion The database described here is designed to serve as a resource for researchers who are venturing into the study of poorly described chloroplast genomes, whether for large- or small-scale DNA sequencing projects, to study molecular variation or to investigate chloroplast evolution.

Throughout the history of humanity, numerous therapeutic agents have been employed for their sedative and hypnotic properties such as opium, henbane (Hyoscyamus niger) and deadly nightshade (Atropa belladonna), but also alcohol and wine. In the 19th century potassium bromide was introduced as a sedative - and antiepileptic drug and chloral hydrate as sedative-hypnotics. A new era was reached by the introduction of barbiturates. The story started with the chemist Adolf von Baeyer. His breakthrough in the synthesis of new agents as barbituric acid and indigo and his education of young chemists was of great importance for the science of organic chemistry and the development of the dye and medicine industry in the late 19th century. The next important step was the development of barbiturates. The pioneers were Josef von Mering and Emil Fischer. Using the Grimaux-method they synthesized various barbiturates. It was von Mering who got the idea of introducing ethyl groups in the inactive barbituric acid to obtain sedatives, but the synthesis was succeeded by the chemist Emil Fischer. Experiments with dogs clearly showed sedative and hypnotic effect of the barbiturates and the oral administration of barbital (Veronal) confirmed the effect in humans. Barbital was commercialized in 1903 and in 1911 phenobarbital (Luminal) was introduced in the clinic, and this drug showed hypnotic and antiepileptic effects. Thereafter a lot of new barbiturates appeared. Dangerous properties of the drugs were recognized as abuse, addiction, and poisoning. An optimum treatment of acute barbiturate intoxication was obtained by the "Scandinavian method", which was developed in the Poison Centre of the Bispebjerg Hospital in Copenhagen. The centre was established by Carl Clemmesen in 1949 and the intensive care treatment reduced the mortality of the admitted persons from 20% to less than 2%. To-day only a few barbiturates are used in connection with anaesthesia and for the treatment of epilepsy

Ingestions of plants rarely lead to life-threatening intoxications. Highly toxic plants, which can cause death, are monkshood (Aconitum sp.), yew (Taxus sp.) and autumn crocus (Colchicum autumnale). Lethal ingestions of monkshood and yew are usually suicides, intoxications with autumn crocus are mostly accidental ingestions of the leaves mistaken for wild garlic (Allium ursinum). Severe intoxications can occur with plants of the nightshade family like deadly nightshade (Atropa belladonna), angel's trumpet (Datura suaveolens) or jimsonweed (Datura stramonium). These plants are ingested for their psychoactive effects. Ingestion of plant material by children most often only causes minor symptoms or no symptoms at all, as children usually do not eat great quantities of the plants. They are especially attracted by the colorful berries. There are plants with mostly cardiovascular effects like monkshood, yew and Digitalis sp. Some of the most dangerous plants belong to this group. Plants of the nightshade family cause an anticholinergic syndrome. With golden chain (Laburnum anagyroides), castor bean (Ricinus communis) and raw beans (Phaseolus vulgaris) we see severe gastrointestinal effects. Autumn crocus contains a cell toxin, colchicine, which leads to multiorgan failure. Different plants are irritative or even caustic to the skin. Treatment is usually symptomatic. Activated charcoal is administered within one hour after ingestion (1 g/kg). Endoscopic removal of plant material can be considered with ingestions of great quantities of highly toxic plants. Administration of repeated doses of charcoal (1-2 g/h every 2-4 hours) may be effective in case of oleander poisoning. There exist only two antidotes: Anti-digoxin Fab fragments can be used with cardenolide glycoside-containing plants (Digitalis sp., Oleander). Physostigmine is the antidote for severe anticholinergic symptoms of the CNS. Antibodies against colchicine, having been developed in France, are not available at

An antifungal protein, designated MCha-Pr, was isolated from the intercellular fluid of bitter gourd (Momordica charantia) leaves during a screen for potent antimicrobial proteins from plants. The isolation procedure involved a combination of extraction, ammonium sulphate precipitation, gel filtration on Bio-Gel P-6, ion exchange chromatography on CM-Sephadex, an additional gel filtration on HiLoad 16/60 Superdex 30, and finally, HPLC on a SOURCE 5RPC column. Matrix-assisted laser desorption/ionisation time-of-flight mass spectrometry indicated that the protein had a molecular mass of 25733.46Da. Automated Edman degradation was used to determine the N-terminal sequence of MCha-Pr, and the amino acid sequence was identified as V-E-Y-T-I-T-G-N-A-G-N-T-P-G-G. The MCha-Pr protein has some similarity to the pathogenesis-related proteins from Atropa belladonna (deadly nightshade), Solanum tuberosum (potato), Ricinus communis (castor bean), and Nicotiana tabacum (tobacco). Analysis of the circular dichroism spectra indicated that MCha-Pr predominantly contains α-helix and β-sheet structures. MCha-Pr had inhibitory effects towards a variety of fungal species and the 50% inhibition of fungal growth (IC50) for Alternaria brassicae, Cercospora personata, Fusarium oxysporum, Mucor sp., and Rhizoctonia solani are 33 μM, 42 μM, 37 μM, 40 μM, and 48 μM, respectively. In addition, this antifungal protein can inhibit the germination of A. brassicae spores at 12.5 μM. These results suggest that MCha-Pr in bitter gourd leaves plays a protective role against phytopathogens and has a wide antimicrobial spectrum. Copyright © 2014 Elsevier Inc. All rights reserved.

The Solanaceae are a cosmopolitan family containing many essential vegetables and fruits such as potato (Solanum tuberosum L.), tomato (Lycopersicon esculentum L.), eggplant (Solanum melongena L.), paprika, chillies, green and red peppers (Capsicum annuum L.), jasmine nightshade (Solanum jasminoides Paxt.), winter cherry (Solanum pseudocapsicum L.), and Cape gooseberry, ornamentals such as Petunia, Schizanthus, and Lycium species, and medicinal plants such as bittersweet (Solanum dulcamara L.) and Solanum viarum Dun., both used as sources of corticosteroids. It also contains tobacco (Nicotiana spp.) - one of the most harmful yet economically important plants in the world - together with many other plants of both poisonous and medicinal value such as belladonna (Atropa belladona L.), stramonium (Datura stramonium L.), black henbane (Hyoscyamus niger L.), and African nightshade (Solanum villosum). Composed of approximately 90 genera and between 2000 and 3000 species, the family is widely distributed throughout the tropical and temperate regions of the world, with centers of diversity occurring in Central and South America, Australia, and Africa (EDMONDS 1978; SYMON 1981; D'ARCY 1991). Work to develop new varieties of improved solanaceous crops started more than 2 centuries ago. This paper reviews some of the recent developments in various aspects of varietal improvement of solanaceous vegetables through mutation breeding. Mutational work reported here includes the alteration of plant reproductive or vegetative growth and the development of locally adapted cultivars and popular breeding lines, or the induction of novel alleles. The potential for direct application of the mutants as new improved cultivars, their use in cross-breeding schemes, and their application in, for example, marker technology in genetic research are discussed. Specific examples of novel mutants developed in our laboratory that have the potential for application in improving solanaceous fruits
The study described here provided evidence to prove that considerable quantities of ethylene oxide, ethylene chlorhydrin and ethylene glycol are retained, when a drug is fumigated with ethylene oxide under standard fumigation conditions in order to reduce the germ number. Ethylene oxide bound by adsorption may be eliminated from the drug by repeated aeration. If an aqueous-ethanolic percolate is prepared from a drug showing very high levels of ethylene chlorhydrin and then carefully distilled at 40 C using only little pressure, a dry extract can be obtained that contains no such residue.

Full Text Available Abstract Background One of the cardinal principles of homeopathy is the "law of similarities", according to which patients can be treated by administering substances which, when tested in healthy subjects, cause symptoms that are similar to those presented by the patients themselves. Over the last few years, there has been an increase in the number of pre-clinical (in vitro and animal studies aimed at evaluating the pharmacological activity or efficacy of some homeopathic remedies under potentially reproducible conditions. However, in addition to some contradictory results, these studies have also highlighted a series of methodological difficulties. The present study was designed to explore the possibility to test in a controlled way the effects of homeopathic remedies on two known experimental models of acute inflammation in the rat. To this aim, the study considered six different remedies indicated by homeopathic practice for this type of symptom in two experimental edema models (carrageenan- and autologous blood-induced edema, using two treatment administration routes (sub-plantar injection and oral administration. Methods In a first phase, the different remedies were tested in the four experimental conditions, following a single-blind (measurement procedure. In a second phase, some of the remedies (in the same and in different dilutions were tested by oral administration in the carrageenan-induced edema, under double-blind (treatment administration and measurement and fully randomized conditions. Seven-hundred-twenty male Sprague Dawley rats weighing 170–180 g were used. Six homeopathic remedies (Arnica montana D4, Apis mellifica D4, D30, Atropa belladonna D4, Hamamelis virginiana D4, Lachesis D6, D30, Phosphorus D6, D30, saline and indomethacin were tested.

A liquid-dispersed reactor equipped with a vertical mesh cylinder for inoculum support was developed for culture of Atropa belladonna hairy roots. The working volume of the culture vessel was 4.4 L with an aspect ratio of 1.7. Medium was dispersed as a spray onto the top of the root bed, and the roots grew radially outward from the central mesh cylinder to the vessel wall. Significant benefits in terms of liquid drainage and reduced interstitial liquid holdup were obtained using a vertical rather than horizontal support structure for the biomass and by operating the reactor with cocurrent air and liquid flow. With root growth, a pattern of spatial heterogeneity developed in the vessel. Higher local biomass densities, lower volumes of interstitial liquid, lower sugar concentrations, and higher root atropine contents were found in the upper sections of the root bed compared with the lower sections, suggesting a greater level of metabolic activity toward the top of the reactor. Although gas-liquid oxygen transfer to the spray droplets was very rapid, there was evidence of significant oxygen limitations in the reactor. Substantial volumes of non-free-draining interstitial liquid accumulated in the root bed. Roots near the bottom of the vessel trapped up to 3-4 times their own weight in liquid, thus eliminating the advantages of improved contact with the gas phase offered by liquid-dispersed culture systems. Local nutrient and product concentrations in the non-free-draining liquid were significantly different from those in the bulk medium, indicating poor liquid mixing within the root bed. Oxygen enrichment of the gas phase improved neither growth nor atropine production, highlighting the greater importance of liquid-solid compared with gas-liquid oxygen transfer resistance. The absence of mechanical or pneumatic agitation and the tendency of the root bed to accumulate liquid and impede drainage were identified as the major limitations to reactor performance. Improved

Translocation of two Rac/Rop guanosine 5'-triphosphate-binding proteins from Scoparia dulcis, Sdrac-1 and Sdrac-2, was examined employing transformed belladonna which overproduces these proteins as glutathione-S-transferase-tagged forms. The transferase activities of the fused proteins in microsomal fraction of belladonna markedly increased by the incubation with methyl jasmonate either in Sdrac-1 or Sdrac-2 transformant, while low and constant activities were observed in the untreated control. Recombinant Sdrac-2 protein was found to bind to prenyl chain in the presence of cell extracts prepared from methyl jasmonate-treated S. dulcis, however, Sdrac-1 was palmitoylated by the addition of the cell extracts. These results suggest that both Sdrac-1 and Sdrac-2 translocate to plant membranes by the stimulation with methyl jasmonate, however, targeting of these proteins is triggered by the independent modification mechanisms, palmitoylation for Sdrac-1 and prenylation for Sdrac-2.

Pollen tube growth in the style (Petunia ♀xNicotiana ♂) accelerated wilting. Pollination and germination on the stigmatic surface (Petunia ♀xAtropa ♂) did not change the stage of flowering in comparison with unpollinated flowers. Wilting of the corolla was accelerated by cutting off the stigma or cutting the style half-way down. Removal of the entire style also brought about an acceleration, however, to a lesser extent. The role of the style as a sense-organ with regard to the transmission of information from stigma and style to other flower organs is discussed.
Full Text Available Abstract Background Breast gangrene is rare in surgical practice. Gangrene of breast can be idiopathic or secondary to some causative factor. Antibiotics and debridement are used for management. Acute inflammatory infiltrate, severe necrosis of breast tissue, necrotizing arteritis, and venous thrombosis is observed on histopathology. The aim of was to study patients who had breast gangrene. Methods A prospective study of 10 patients who had breast gangrene over a period of 6 years were analyzed Results All the patients in the study group were female. Total of 10 patients were encountered who had breast gangrene. Six patients presented with breast gangrene on the right breast whereas four had on left breast. Out of 10 patients, three had breast abscess after teeth bite followed by gangrene, one had iatrogenic trauma by needle aspiration of erythematous area of breast under septic conditions. Four had history of application of belladonna on cutaneous breast abscess and had then gangrene. All were lactating female. Amongst the rest two were elderly, one of which was a diabetic who had gangrene of breast and had no application of belladonna. All except one had debridement under cover of broad spectrum antibiotics. Three patients had grafting to cover the raw area. Conclusion Breast gangrene occurs rarely. Etiology is variable and mutifactorial. Teeth bite while lactation and the iatrogenic trauma by needle aspiration of breast abscess under unsterlised conditions could be causative. Uncontrolled diabetes can be one more causative factor for the breast gangrene. Belladonna application as a topical agent could be inciting factor. Sometimes gangrene of breast can be idiopathic. Treatment is antibiotics and debridement.

Full Text Available The effect of high dilution preparations on the movement and foraging activities of Atta sexdens piriventris was evaluated. Five colonies of ants were located on each of the five experimental areas using a randomized complete block design. Three main forage trails from each colony were selected from where evaluations were made. Ten mL of high dilution preparation of Atta sexdens piriventris nosodes and Belladonna homeopathy solution were sprayed over 0.5 m of each selected trail, 1.0 m far from the nest. The controls were pure water and non treated trails. Applications were made daily during 10 days. The total number of ants moving on each trail one meter away from the nest, carrying or not plant fragments, were assessed before the daily application. Dilution preparations at 30CH (thirtieth centesimal Hahnemannian dilution of A. sexdens piriventris nosodes and Belladonna reduced the activities of ants from the fifth day after the first application. The treatment effect lasted more than 20 days after the last application. The use of preparation at 30CH dilution order to reduce the foraging activity of leaf-cutting ants is a potential non residual method to manage leaf-cutting ants.
Full Text Available The effect of homeopathic preparations on the activities of the leaf-cutting ants Acromyrmex spp. was studied. A field experiment involving ant nests in six experimental areas was performed using a randomised complete block design. Within each block, every ant nest was considered to represent one repetition. The treatments consisted of the following: Belladonna homeopathic preparations of macerated or triturated Acromyrmex spp. adults, homeopathic preparations of macerated or triturated ant nest fungus (Leucoagaricus gongylophorus collected from Acromyrmex laticeps and Acromyrmex heyeri nests, a homeopathy Belladonna, and dynamised water. All of the homeopathic treatments were tested at the 30 CH (thirtieth centesimal Hahnemannian dynamisation. An untreated nest served as the control. The total number of ants from each trail was counted, including both those carrying or not-carrying green plant fragments, immediately before the daily homeopathic applications. All of the tested homeopathic preparations, except for the water, significantly reduced the activity level of Acromyrmex spp. The homeopathic preparations of Belladonna and the macerated nosodes of Acromyrmex spp. reduced the activity level of the ants beginning with the sixth day after the first treatment application; the activity level reduction effect lasted more than 20 days after the last application.O efeito de preparados homeopáticos sobre as atividades de formigas cortadeiras Acromyrmex spp. foi estudado. O experimento foi realizado no campo, utilizando formigueiros distribuídos em seis diferentes áreas. Em cada área cada, formigueiro foi considerado uma repetição. Os tratamentos consistiram de preparados homeopáticos obtidos da tintura-mãe dos triturados e macerados de adultos de Acromyrmex spp. e do fungo Leucoagaricus gongylophorus de formigueiros de Acromyrmex laticeps e Acromyrmex heyeri. A homeopatia Belladonna e água dinamizada também foram testados. Todos os

This is a review of Ibn al Quff's account of surgical pain relief in his surgical book Al Omdah, in which he mentioned the word anesthetic (Al moukhadder) and the involvement of physician (al tabbaaee) to give mixture of drugs to prevent pain in a surgical condition to relieve the patient from pain or to make surgical management possible. Hich indicated one rare occasion to such description in Arabic medical texts. Methods of administration of these drugs were inhalation, ingestion and by rectal suppositories. The drugs used in anesthetic sponges include all the drugs that are recorded in the modern literature of anesthesia. They are as follows: opium, mandrake, Hyocymus albus, belladonna, Cannabis sativus, Cannabis indica, wild lettuce. The anesthetic sponge, mentioned in many references as an inhalation method, may be of symbolic value to surgery. PMID:25885079
Full Text Available R Migliorini, R Malagola, M Mafrici, R Spena, L ArricoDepartment of Sense Organs, University of Rome "La Sapienza", Rome, ItalyAbstract: Hyoscine-N-butyl bromide is a widely used antispasmodic belonging to the belladonna alkaloid class of semisynthetic quaternary ammonium compounds. These compounds exert a spasmolytic action on the smooth muscles of the bile-gastrointestinal tract, genitourinary tract, salivary glands (xerostomia, and also on the visual apparatus – in particular, the irido-ciliary complex. As a consequence, they provoke collateral effects such as mydriasis and accommodation disturbances. We report the case of a 23-year-old woman who complained of not only "dry mouth" but also "cloudy vision" and a "diplopia", both of temporary type, 2 hours after oral administration of hyoscine-N-butyl bromide.Keywords: hyoscine-N-butyl bromide, accommodation disorders, temporary diplopia, fusion alteration, vertical strabismus

In this case report we illustrate how incorrectly prepared and cooked seeds from white lupin - a common snack among people from parts of the Mediterranean and Middle East - caused an anticholinergic syndrome in a previously healthy man. The symptoms subsided without treatment and the patient was discharged from the hospital in good health. Anticholinergic syndrome results from inhibition of the parasympatic nervous system. The symptoms commonly include dry mouth, confusion, hallucinations, fever, tachycardia, and urine retention. The syndrome may most frequently be provoked by overdose of drugs such as prometazin, hyoscyamin, and biperidin or by ingestion of plants such as belladonna, datura and henbane. The aim of this report is to increase clinicians' awareness of white lupin's anticholinergic effects.

A unique combination of genetic features and a rich stock of information make the flowering plant genus Oenothera an appealing model to explore the molecular basis of speciation processes including nucleus-organelle coevolution. From representative species, we have recently reported complete nucleotide sequences of the 5 basic and genetically distinguishable plastid chromosomes of subsection Oenothera (I-V). In nature, Oenothera plastid genomes are associated with 6 distinct, either homozygous or heterozygous, diploid nuclear genotypes of the 3 basic genomes A, B, or C. Artificially produced plastome-genome combinations that do not occur naturally often display interspecific plastome-genome incompatibility (PGI). In this study, we compare formal genetic data available from all 30 plastome-genome combinations with sequence differences between the plastomes to uncover potential determinants for interspecific PGI. Consistent with an active role in speciation, a remarkable number of genes have high Ka/Ks ratios. Different from the Solanacean cybrid model Atropa/tobacco, RNA editing seems not to be relevant for PGIs in Oenothera. However, predominantly sequence polymorphisms in intergenic segments are proposed as possible sources for PGI. A single locus, the bidirectional promoter region between psbB and clpP, is suggested to contribute to compartmental PGI in the interspecific AB hybrid containing plastome I (AB-I), consistent with its perturbed photosystem II activity.

There is a wealth of information about the nutritional and medicinal properties of honey. However, honey may contain compounds that may lead to toxicity. A compound not naturally present in honey, named 5-hydroxymethylfurfural (HMF), may be formed during the heating or preservation processes of honey. HMF has gained much interest, as it is commonly detected in honey samples, especially samples that have been stored for a long time. HMF is a compound that may be mutagenic, carcinogenic and cytotoxic. It has also been reported that honey can be contaminated with heavy metals such as lead, arsenic, mercury and cadmium. Honey produced from the nectar of Rhododendron ponticum contains alkaloids that can be poisonous to humans, while honey collected from Andromeda flowers contains grayanotoxins, which can cause paralysis of limbs in humans and eventually leads to death. In addition, Melicope ternata and Coriaria arborea from New Zealand produce toxic honey that can be fatal. There are reports that honey is not safe to be consumed when it is collected from Datura plants (from Mexico and Hungary), belladonna flowers and Hyoscamus niger plants (from Hungary), Serjania lethalis (from Brazil), Gelsemium sempervirens (from the American Southwest), Kalmia latifolia, Tripetalia paniculata and Ledum palustre. Although the symptoms of poisoning due to honey consumption may differ depending on the source of toxins, most common symptoms generally include dizziness, nausea, vomiting, convulsions, headache, palpitations or even death. It has been suggested that honey should not be considered a completely safe food. Copyright © 2013 John Wiley & Sons, Ltd.

Infantile nystagmus syndrome (INS) is a disorder characterized by typical horizontal eye oscillations. Due to the uncertain etiology of INS, developing specific treatments remains difficult. Single reports demonstrated, on limited measures, alleviating effects of gabapentin and memantine. In the current study, we employed the zebrafish INS model belladonna (bel) to conduct an in-depth study of how gabapentin and memantine interventions alleviate INS signs, which may further restore visual conditions in affected subjects. Moreover, we described the influence of both medications on ocular motor functions in healthy zebrafish, evaluating possible iatrogenic effects. Ocular motor function and INS characteristics were assessed by eliciting optokinetic response, spontaneous nystagmus, and spontaneous saccades in light and in dark, in 5- to 6-day postfertilization bel larvae and heterozygous siblings. Single larvae were recorded before and after a 1-hour drug treatment (200 mM gabapentin/0.2 mM memantine). Both interventions significantly reduced nystagmus intensity (gabapentin: 59.98%, memantine: 39.59%). However, while the application of gabapentin affected all tested ocular motor functions, memantine specifically reduced nystagmus amplitude and intensity, and thus left controls completely unaffected. Finally, both drug treatments resulted in specific changes in nystagmus waveform and velocity. Our study provides deeper insight into gabapentin and memantine treatment effect in the zebrafish INS model. Moreover, this study should establish zebrafish as a pharmacologic animal model for treating nystagmus and ocular motor disease, serving as a basis for future large-scale drug screenings.

Datura Stramonium (DS) is a common weed along roadsides, in cornfields and pastures and in waste areas. It belongs to the family Solanaceae and its toxic components are tropane belladonna alkaloids. It has been used voluntarily by teenagers for its hallucinogenic effect. The plant is named in Iran as Tatoore. Symptoms and signs of acute D. Stramonium poisoning usually are similar to anticholinergic syndrome. This study is done in order to clarify the status of this poisoning in our region. This study is a case series on all patients admitted to Imam Reza Hospital, Mashhad, Iran, with acute D. Stramonium poisoning between 2008 and 2011. We observed their symptoms, signs, routine laboratory test results and treatment used to control their symptoms. There were 19 patients included in our study. Children were poisoned more commonly than teenagers and poisoning in adults was rare. All of the children ingested the plant accidentally. The most presenting symptom was irritability and the most common sign was sinus tachycardia. There was not any presentation of seizure or coma. Most of the symptoms were controlled by parenteral benzodiazepines and there were no need to use of cholinergic agents such as physostigmine. Our study showed most of D. Stramonium poisoned population in our region are children. We suggest decreasing accessibility to the plant in order to decrease the incidence of its poisoning.

Full Text Available Background: Alcohol dependence is a common social problem which may be associated with other risk factors and co-morbidities. Abrupt cessation of alcohol intake may provoke an acute alcohol withdrawal phase with varying degrees of signs and symptoms. In conventional medical system, specific pharmacological interventions are used for management of Acute Alcohol Withdrawal (AAW. There exists a need to explore safe and holistic treatment of AAW. The present work reports the results of a prospective, observational, exploratory, multicentre trial (2008-2011 to assess the role of Homoeopathy in AAW. Materials and Methods: Individualised Homoeopathy was given to 112 patients reporting with AAW. The clinical assessment was done for 05 days using Clinical Institute Withdrawal Assessment Scale of Alcohol-Revised (CIWA-Ar. Post-withdrawal phase, quality of life of patients was assessed at end of 01 st , 03 rd and 06 th month using World Health Organisation quality of life (WHOQOL- BREF. Results and Analysis: There was a significant decrease in CIWA-Ar mean scores and increase in quality of life score (P < 0.001. The most common remedies used were Arsenicum album, Lycopodium clavatum, Belladonna, Nux vomica and Pulsatilla. Conclusion: The results of current observational pilot study suggest the promising use of Homoeopathy in the management of acute alcohol withdrawal. Further studies with large sample size and rigorous design are warranted.

Tropane alkaloids (TAs) are toxic secondary metabolites produced by plants of, inter alia, the genera Datura (thorn apple) and Atropa (deadly nightshade). The most relevant TAs are (-)-L-hyoscyamine and (-)-L-scopolamine, which act as antagonists of acetylcholine muscarinic receptors and can induce a variety of distinct toxic syndromes in mammals (anti-cholinergic poisoning). The European Union has regulated the presence of seeds of Datura sp. in animal feeds, specifying that the content should not exceed 1000 mg kg(-1) (Directive 2002/32/EC). For materials that have not been ground, visual screening methods are often used to comply with these regulations, but these cannot be used for ground materials and compound feeds. Immunological assays, preferably in dipstick format, can be a simple and cost-effective approach to monitor feedstuffs in an HACCP setting in control laboratories. So far no reports have been published on immunoassays that are capable of detecting both hyoscyamine and scopolamine with equal sensitivity and that can be used, preferably in dipstick format, for application as a fast screening tool in feed analysis. This study presents the results obtained for the in-house and inter-laboratory validation of a dipstick immunoassay for the detection of hyoscyamine and scopolamine in animal feed. The target level was set at 800 µg kg(-1) for the sum of both alkaloids. By using a representative set of compound feeds during validation and a robust study design, a reliable impression of the relevant characteristics of the assay could be obtained. The dipstick test displayed similar sensitivity towards the two alkaloids and it could be concluded that the test has a very low probability of producing a false-positive result at blank level or a false-negative result at target level. The assay can be used for monitoring of TAs in feedstuffs, but has also potential as a quick screening tool in food- or feed-related poisonings.

Hyoscyamine and scopolamine, anti-cholinergic agents widely used in medicine, are typically obtained from plants grown under natural conditions. Since field cultivation entails certain difficulties (changeable weather, pests, etc.), attempts have been made to develop a plant in vitro culture system as an alternative source for the production of these compounds. During experiments to locate the limiting steps in the biotechnological procedure, it is important to monitor not only the levels of the final products but also the changes in the concentration of their precursors. To develop a HPTLC method for the separation and quantitation of the main tropane alkaloids hyoscyamine and scopolamine, their respective direct precursors littorine and anisodamine, and cuscohygrine, a product of a parallel biosynthetic pathway that shares a common precursor (N-methyl-∆(1) -pyrrolium cation) with tropane alkaloids. Using alkaloid extracts from Atropa baetica hairy roots, different TLC chromatographic systems and developing procedures were investigated. Full separation of all compounds was obtained on HPTLC Si60 F254 plates preconditioned with mobile phase vapours (chloroform:methanol:acetone:25% ammonia ratios of 75:15:10:1.8, v/v/v/v). The chromatograms were developed twice (at distances of 4.0 and 3.0 cm) in a Camag twin trough chamber and visualised with Dragendorff's reagent. Densitometric detection (λ = 190 and 520 nm) was used for quantitative analyses of the different plant samples. This method can be recommended for quantitation of hyoscyamine, scopolamine, anisodamine, littorine and cuscohygrine in different plant material (field grown vs. in vitro cultures).

Since the application of technical medicine by the Greeks, modern neurology has been based on a body of knowledge and cultural heritage from ancient times. In this paper we review the contribution made by Al Andalus to neuroscience during the Middle Ages and its repercussions on modern neurology. Following the death of Mohammed in the vii century AD, Islam enjoyed one of the most spectacular periods of expansion in the history of mankind. Occupation of the cities of Alexandria and Gundishapur put the Arabs into contact with original Greco Latin manuscripts, which were assimilated and divulged by Islamic scientists in the middle eastern caliphates of Damascus and Bagdad as well as the western caliphates of Al Andalus (Spain) and Kairwan (Tunis). This classical hippocratico galenico medicine was refashioned into the so called arabized galenism, which markedly influenced the Scholastics and the cultured world of the lower Middle Ages and became the basis of European medicine until well into the Renaissance period. There was a first Spanish cultural Renaissance in Al Andalus during the ix xii centuries, which led to a flowering unheard of in the Middle Ages before then. Andalusian doctors made major contributions to the body of knowledge about neuroscience and developed major philosophical concepts of human understanding. Thus, Abulcasis (936 1013), the father of modern surgery, developed material and technical designs which are still used in neurosurgery. Averroes suggested the existence of Parkinson s syndrome and attributed photoreceptor properties to the retina. Avenzoar described meningitis, intracranial thrombophlebitis, mediastinal tumours and made contributions to modern neuropharmacology. Maimonides wrote about neuropsychiatric disorders and described rabies and belladonna intoxication. Aside from the political, religious and cultural differences between Al Andalus and the Christian kingdoms of the Iberian peninsula, the historical Andalusian period (711 1492

Full Text Available Postoperative nausea and vomiting is one of the most common and undesirable complaints recorded in as many as 70%-80% of high-risk surgical patients. The current prophylactic therapy recommendations for PONV management stated in the Society of Ambulatory Anesthesia guidelines should start with monotherapy and patients at moderate to high risk, a combination of antiemetic medication should be considered. Consequently, if rescue medication is required, the antiemetic drug chosen should be from a different therapeutic class and administration mode than the drug used for prophylaxis. The guidelines restrict the use of dexamethasone, transdermal scopolamine, aprepitant, and palonosetron as rescue medication 6 hours after surgery. In an effort to find a safer and reliable therapy for postoperative nausea and vomiting, new drugs with antiemetic properties and minimal side effects are needed, and scopolamine may be considered an effective alternative. Scopolamine is a belladonna alkaloid, α-(hydroxymethyl benzene acetic acid 9-methyl-3-oxa-9-azatricyclo non-7-yl ester, acting as a nonselective muscarinic antagonist and producing both peripheral antimuscarinic and central sedative, antiemetic, and amnestic effects. The empirical formula is C17H21NO4 and its structural formula is a tertiary amine L-(2-scopolamine (tropic acid ester with scopine; MW = 303.4. Scopolamine became the first drug commercially available as a transdermal therapeutic system used for extended continuous drug delivery during 72 hours. Clinical trials with transdermal scopolamine have consistently demonstrated its safety and efficacy in postoperative nausea and vomiting. Thus, scopolamine is a promising candidate for the management of postoperative nausea and vomiting in adults as a first line monotherapy or in combination with other drugs. In addition, transdermal scopolamine might be helpful in preventing postoperative discharge nausea and vomiting owing to its long

Full Text Available The present work is the 1st part of 3-part study carried out at Fayoum Governorate, Egypt to evaluate the pollen species collected by honey bee, Apis mellifera L., colonies during two successive years, 2009 and 2010. Obtained results showed that, in 2009, total amount of trapped pollen (fresh weight was 2354.89 g/colony/year (mean 588.72 g/colony/season, with peaks in summer and spring, while declined in autumn and winter. Correlation between mean maximum and minimum temperatures and weekly pollen weights was highly positive, while it was insignificant for relative humidity. In 2010, total amount of trapped pollen decreased to 1635.36 g/colony/year (mean 408.84 g/colony/season. The largest amounts were collected in summer followed by winter then spring, while least ones were in autumn. Correlation was highly positive between weekly mean of pollen weights and maximum temperature, while it was insignificant for minimum temperature or relative humidity. There were 24 plant species of 16 botanical families from which bees collected pollen. These sources were ranked according to their predominant quantities in the 1st and 2nd years by two numbers, respectively as the following: sesame 1 and 1, maize 2 and 2, clover 3 and 7, sunflower 4 and 8, wild mustard 5 and 3, casuarina 6 and 13, olive 7 and 11, eucalyptus 8 and 4, pumpkin 9 and 9, cocklebur 10 and 5, date palm 11 and 10, chamomile 12 and 12, field bindweed 13 and 6, pepper 14 and 20, coriander 15 and 16, acacia 16 and 24, citrus 17 and 0, marigold 18 and 0, common red 19 and 17, Christ’s thorn 20 and 22, tooth pick 21 and 21, brood bean 22 and 15, belladonna 23 and 23, pea 0 and 14, marjoram 0 and 18 and fennel 0 and 19. The 1st five plants seem to be the main pollen sources for honey bee colonies and consequently pollen producing during the whole year in the tested region. These sources represented 75.61% and 66.95% of the total annual yield in the two surveyed years, respectively.

Full Text Available By the end of the 18th and the beginning of the 19th century a new era began in medicine, pharmaceutics and chemistry that was strongly connected with alkaloids and alkaloid drugs. Even before that it was known that certain drugs administered in limited doses were medicines, and toxic if taken in larger doses (opium, coke leaves, belladonna roots, monkshood tubers crocus or hemlock seeds. However, the identification, isolation and structural characterization of the active ingredients of the alkaloid drugs was only possible in the mid 20th century by the use of modern extraction equipment and instrumental methods (NMR, X-ray diffraction and others.In spite of continuing use over a long time, there is still great interest in investigating new drugs, potential raw materials for the pharmaceutical industry, as well as the more detailed investigation and definition of bio-active components and the indication of their activity range, and the partial synthesis of new alkaloid molecules based on natural alkaloids. The scope of these investigations, especially in the field of semi-synthesis is to make better use of the bio-active ingredients of alkaloid drugs, i.e. to improve the pharmacological effect (stronger and prolonged effect of the medicine, decreased toxicity and side effects, or to extend or change the applications. A combined classification of alkaloids was used, based on the chemical structure and origin, i.e. the source of their isolation to study alkaloid structure. For practical reasons, the following classification of alkaloids was used: ergot alkaloids, poppy alkaloids, tropanic alkaloids purine derivative alkaloids, carbon-cyclic alkaloids, and other alkaloids. The second part of this report presents a table of general procedures for alkaloid isolation from plant drugs (extraction by water non-miscible solvents, extraction by water-miscible solvents and extraction by diluted acid solutions. Also, methods for obtaining chelidonine and

Other substances of animal or mineral origin were also used in the preparation of these compounds (toads, arsenic. Finally, we have analyzed the possible documentary sources in scientific matter that could be used by these two prominent writers, such as the Dioscorides commented by Andrés Laguna in both cases, and Pliny’s Natural History, commented on by Francisco Hernández and Gerónimo de Huerta, and the booklet Il Sapere Util’e Delettevole by Constantino Castriota, in the particular case of Lope de Vega.
