Abstract
Background Mucuna pruriens (L.) has been used for the treatment of several ailments in folkloric medicine. The present study therefore investigates the hepatoprotective and nephroprotective potentials of its leaves extract with a view to providing a potent alternative in the management of liver and kidney diseases. Methodology Forty male albino rats were randomly placed into eight groups comprising five animals each. Animals in group I were administered with the distilled water, while groups II and VI were exposed to CCl4 and rifampicin respectively. Animals in groups III and IV were initially exposed CCl4 and treated with 50 and 100 mg/kg bw M. pruriens respectively. Similarly, groups VII and VIII animals were exposed to rifampicin and treated with 50 and 100 mg/kg bw M. pruriens respectively. Animals in group V were treated with 100 mg/kg bw silymarin by oral gavage after an initial exposure to CCl4. Selected biomarkers of liver and kidney damage were determined in the serum and organs homogenate. Liver and kidney slices of experimental animals were also stained for histopathological examination. Results Exposure to CCl4 and rifampicin respectively resulted in marked distortion in lipid profile, inhibition of antioxidant enzymes and a surge in ALT, AST, ALP, urea, uric acid, bilirubin and creatine kinase. Treatment with M. pruriens extract reversed all deranged biochemical and histopathological parameters in a dose-dependent manner. Conclusion Extract of M. pruriens leaves restored deranged biochemical and histopathological parameters in the liver and kidney with similar potency to silymarin. Hence, leaf extract of M. pruriens is a potential hepatoprotective and nephroprotective agent that can be exploited in the management of liver and kidney diseases.

Abstract
BACKGROUND The World Health Organization included snakebite envenomation among Neglected Tropical Diseases in 2017. The importance of natural products from plants is enormous, given that most prescribed drugs originate from plants. Among this is Mucuna pruriens and Mimosa pudica, with many registered patents asserting their health benefits. OBJECTIVE This study investigated the in vitro neutralizing effects of Mucuna pruriens seed and Mimosa pudica root extracts on venoms of Naja nigricollis and Bitis arietans. METHODS In mice, the LD50 and phytochemical analysis of M. pruriens and M. pudica plant extracts were carried out prior to the evaluation of their haemolytic and fibrinolytic effect. Their effects on the activities of phospholipase A2 (PLA2) were also assessed. RESULTS At a concentration of 50 mg/ml, both plant extracts were found to neutralize the fibrinolytic activity of N. nigricollis, but 400 mg/ml was required to neutralize the fibrinolytic activity of B. arietans. In haemolytic studies, 50 mg/ml concentration of M. pruriens extract suppressed haemolysis caused by N. nigricollis venom by 70% but at the same concentration, M. pudica extract reduced haemolysis by 49.4%. M. pruriens, at 50 mg/ml concentration, only inhibited phospholipase A2 activity by 7.7% but higher concentrations up to 400mg/ml had no effect against the venom of N. nigricollis; at 200 mg/ml. M. pudica extract inhibited PLA2 activity by 23%. CONCLUSION The results suggest that M. pruriens and M. pudica may be considered as promising antivenom agents for people living in a snake-bite prone environment.

Abstract
The volatile constituents, toxicity, antinociception, and anti-inflammatory activities of the essential oil obtained from the leaf of Mucuna pruriens utilis collected from Nigeria are reported. The essential oil was analyzed comprehensively utilizing gas chromatography (GC)-flame ionization detector and GC coupled with mass spectrometry (MS) using the HP-5 column. The antinociceptive and anti-inflammatory assays were analyzed by a hot plate, formalin, and carrageenan-induced edema assays, respectively. The essential oil was obtained in a yield of 0.2% (v/w) calculated on a dry weight basis. A total of 36 compounds representing 94.8% of the oil contents were identified. The oil contained a high content of ( E)-2-hexenal (19.0%), linalool (8.9%), 1-hexanol (6.6%), and trans-dehydroxylinalool oxide (5.2%). The analgesic property of the essential oil was slightly significant ( P < 0.5) only at the third hour for the 400 mg/kg while other doses are less active. The rate of inhibition was moderate (24.1%-54%) during the analgesic phase of the formalin assay. The rate of inhibition at the anti-inflammatory phases of both formalin and carrageenan were significantly high (100%) and P < 0.001 for all the doses during the reaction duration. The potential proinflammatory mechanism might be due to effects on several proinflammatory mediators, including, histamine, serotonin, and bradykinin, and the ability of the essential oils to act as centrally mediated opioid analgesic. Mucuna pruriens essential oils displayed a high anti-inflammation potential and can be used as a potential centrally mediated opioid antagonist against analgesia.

Abstract
Mucuna pruriens belongs to the Fabaceae family and is ordinarily known as velvet bean, in English cowitch and Hindi Kawaanch. The restorative quality of this bean makes it an excellent component in pharmaceutical and therapeutic applications. Apart from high protein and starch content, these beans contain (l-Dopa) 3, 4-dihydroxy-l-phenylalanine, which exhibits several medicinal properties. However, it is poisonous when ingested by ruminants. The obstruction to the advancement of Mucuna as nutrition or food is the nearness of antinutrients, which are high as opposed to other uncommon vegetables. Also, this legume is considered as a future restorative herb because of its anticholesterolemic, anti-Parkinson, antioxidant, antidiabetic, sexual enhancing, anti-inflammatory, antimicrobial, and antivenom activities. It also exhibits anticancer activities, but very few studies have been done. The seeds of Mucuna pruriens also contain a vast range of phytochemical constituents such as alkaloids, glycosides, saponins, reducing sugars, and tannins, which provide an avenue to explore it for wider applications. This review sheds light on the possible mechanism of action of Mucuna pruriens on some diseases (hypoglycemia, Parkinson's disease, microbial diseases and tumor). and also fills the gap in the studies of Mucuna pruriens. and Further more in vitro and in vivo studies should be done to explore the potential of these seeds against many diseases, its application as a food source, its antinutrient, and harmful properties as well as its nutraceutical perspective.

Abstract
Mortality due to snakebite is a serious public health problem, and available therapeutics are known to induce debilitating side effects. Traditional medicine suggests that seeds of Mucuna pruriens can provide protection against the effects of snakebite. Our aim is to identify the protein(s) that may be important for snake venom neutralization and elucidate its mechanism of action. To this end, we have identified and purified a protein from M. pruriens, which we have named MP-4. The full-length polypeptide sequence of MP-4 was obtained through N-terminal sequencing of peptide fragments. Sequence analysis suggested that the protein may belong to the Kunitz-type protease inhibitor family and therefore may potentially neutralize the proteases present in snake venom. Using various structural and biochemical tools coupled with in vivo assays, we are able to show that MP-4 does not afford direct protection against snake venom because it is actually a poor inhibitor of serine proteases. Further experiments showed that antibodies generated against MP-4 cross-react with the whole venom and provide protection to mice against Echis carinatus snake venom. This study shows that the MP-4 contributes significantly to the snake venom neutralization activity of M. pruriens seeds through an indirect antibody-mediated mechanism.

Abstract
Background Venoms of two cobras, four vipers, a standard antibiotic and an antimycotic, were evaluated comparatively, as antimicrobials. Methods: Six venom concentrations and three of the standard antibiotic and the antimycotic were run in micro-dilution and diffusion plates against the microorganisms. RESULTS: Echis pyramidum, Echis coloratus
and Cerastes cerastes gasperettii highest venom concentrations gave significant growth inhibition zones (GIZ) with
respect to a negative control, except Bitis arietans, whose concentrations were significant. The cobra Walterinnesia aegyptia
had significant venom concentrations more than Naja haje arabica. The Staphylococcus aureus Methicillin Resistant
(MRSA) bacterium was the most susceptible, with a highly (P < 0.001) significant GIZ mean difference followed by
the Gram positive Staphylococcus aureus, (P < 0.001), Escherichia coli (P < 0.001), Enterococcus faecalis (P < 0.001)
and Pseudomonas aeruginosa which, had the least significance (P < 0.05). The fungus Candida albicans was resistant to
both viper and cobra venoms (P > 0.05). The antibiotic Vancomycin was more effective than snake venoms though, they
were more efficient in inhibiting growth of the resistant Pseudomonas aeruginosa. This antibiotic was also inactive
against the fungus, whilst its specific antifungal Fungizone was highly efficient with no antibacterial activity. Conclusions: These findings showed that snake venoms had antibacterial activity comparable to antibiotics, with a directly proportional
relationship of venom concentration and GIZ, though, they were more efficient in combatting resistant types of
bacteria. Both venoms and the standard antibiotic, showed no antifungal benefits.

Abstract
Mucuna pruriens (Fabaceae) is an established herbal drug used for the management of male infertility, nervous disorders, and also as an aphrodisiac. It has been shown that its seeds are potentially of substantial medicinal importance. The ancient Indian medical system, Ayurveda, traditionally used M. pruriens, even to treat such things as Parkinson's disease. M. pruriens has been shown to have anti-parkinson and neuroprotective effects, which may be related to its anti-oxidant activity. In addition, anti-oxidant activity of M. pruriens has been also demonstrated in vitro by its ability to scavenge DPPH radicals and reactive oxygen species. In this review the medicinal properties of M. pruriens are summarized, taking in consideration the studies that have used the seeds extracts and the leaves extracts.

Abstract
Piper longum L. fruits have been traditionally used against snakebites in north-eastern and southern region of India. The aim of the study was to assess the production of antibody response against Russell's viper venom in mice after prophylactic immunization with ethanolic extract of fruits of Piper longum L. and piperine. The mice sera were tested for the presence of antibodies against Russell's viper venom by in vitro lethality neutralization assay and in vivo lethality neutralization assay. Polyvalent anti-snake venom serum (antivenom) manufactured by Haffkine Bio-Pharmaceutical Corporation Ltd. was used as standard. Further confirmation of presence of antibodies against the venom in sera of mice immunized with PLE and piperine was done using indirect enzyme-linked immunosorbent assay (ELISA) and double immunodiffusion test. Treatment with PLE-treated mice serum and piperine-treated mice serum was found to inhibit the lethal action of venom both in the in vitro lethality neutralization assay and in vivo lethality neutralization assay. ELISA testing indicated that there were significantly high (p<0.01) levels of cross reactions between the PLE and piperine treated mice serum and the venom antigens. In double immunodiffusion test, a white band was observed between the two wells of antigen and antibodies for both the PLE-treated and piperine-treated mice serum. Thus it can be concluded that immunization with ethanolic extract of fruits of Piper longum and piperine produced a high titre antibody response against Russell's viper venom in mice. The antibodies against PLE and piperine could be useful in antivenom therapy of Russell's viper bites. PLE and piperine may also have a potential interest in view of the development of antivenom formulations used as antidote against snake bites.

Abstract
Seeds of Mucuna pruriens (L.) DC. (Fabaceae) were analyzed for protein composition of protein bodies isolated from cotyledons. Protein bodies were successfully separated by Lympholyte and those of dry seeds, observed by scanning electron microscope, were elliptical or spherical in shape with a diameter of 5-12 μm. Protein content in dry seed protein bodies was 10.6 mg/g dry weight. Globulin was the largest protein fraction isolated (62.5 %), followed by albumin (18.3 %), glutelin (15.8 %) and prolamin (3.4 %). The prolamin fraction and high glutelin content are uncommon in legumes. SDS-PAGE of albumins, globulins, prolamins and glutelins provided different band numbers and molecular weights under reducing and non reducing conditions and suggested that the albumin fraction is rich in disulphide bonds.

Abstract
Mucuna pruriens Linn. (velvet bean) has been used by native Nigerians as a prophylactic for snakebite. Rats pretreated with M. pruriens seed extract (MPE) have been shown to protect against the lethal and cardiovascular depressant effects of Naja sputatrix (Javan spitting cobra) venoms, and the protective effect involved immunological neutralization of the venom toxins. To investigate further the mechanism of the protective effect of MPE pretreatment against cobra venom toxicity, the actions of Naja sputatrix venom on spontaneously beating rat atria and aortic rings isolated from both MPE pretreated and untreated rats were studied. Our results showed that the MPE pretreatment conferred protection against cobra venom-induced depression of atrial contractility and atrial rate in the isolated atrial preparations, but it had no effect on the venom-induced contractile response of aortic ring preparation. These observations suggested that the protective effect of MPE pretreatment against cobra venom toxicity involves a direct protective action of MPE on the heart function, in addition to the known immunological neutralization mechanism, and that the protective effect does not involve action on blood vessel contraction. The results also suggest that M. pruriens seed may contain novel cardioprotective agent with potential therapeutic value.

Abstract
In Nigeria, Mucuna pruriens seeds are locally prescribed as an oral prophylactic for snake bite and it is claimed that when two seeds are swallowed they protect the individual for a year against snake bites. In order to understand the Mucuna pruriens antisnake properties, the proteins from the acqueous extract of seeds were purified by three chromatographic steps: ConA affinity chromatography, tandem anionic-cationic exchange and gel filtration, obtaining a fraction conventionally called gpMucB. This purified fraction was analysed by SDS-PAGE obtaining 3 bands with apparent masses ranging from 20 to 24 kDa, and by MALDI-TOF which showed two main peaks of 21 and 23 kDa and another small peak of 19 kDa. On the other hand, gel filtration analysis of the native protein indicated a molecular mass of about 70 kDa suggesting that in its native form, gpMucB is most likely an oligomeric multiform protein. Infrared spectroscopy of gpMucB indicated that the protein is particularly thermostable both at neutral and acidic pHs and that it is an all beta protein. All data suggest that gpMucB belongs to the Kunitz-type trypsin inhibitor family explaining the direct anti-snake venom activity of Mucuna pruriens seeds.

Abstract
Extracts from Dipteryx alata bark obtained with different solvents (hexane, dichloromethane, ethyl acetate and methanol) were mixed in vitro with Bothrops jararacussu (Bjssu, 40 μg/mL) and Crotalus durissus terrificus (Cdt, 15 μg/mL) snake venoms, and applied to a mouse phrenic nerve-diaphragm preparation to evaluate the possible neutralization of venom effects. Cdt venom neurotoxic effect was not inhibited by any of the extracts, while the neurotoxic and myotoxic actions of Bjssu venom were decreased by the methanolic extract. This inhibition appears to be augmented by tannins. Dichloromethane bark extract inhibited ~40% of Bjssu venom effects and delayed blockade induced by Cdt. The methodology used to determine which extract was active allows inferring that: (i) phenolic acids and flavonoids contained in the methanolic extract plus tannins were responsible mostly for neutralization of Bjssu effects; (ii) terpenoids from the dichloromethane extract may participate in the anti-Cdt and anti-Bjssu venom effects; (iii) a given extract could not inhibit venoms from different species even if those belong to the same family, so it is improper to generalize a certain plant as antiophidian; (iv) different polarity extracts do not present the same inhibitory capability, thus demonstrating the need for characterizing both venom pharmacology and the phytochemistry of medicinal plant compounds.

Abstract
The mobilization of storage reserves, with particular emphasis on storage proteins of Mucuna pruriens (L.) DC., cotyledons, and embryo was investigated from the ultrastructural and biochemical points of view. Proteins and starch were the two main storage substances in cotyledons, and proteins and lipids were the main ones in the embryo. Embryo protein bodies were smaller and fewer in number than those of cotyledons. Structural and ultrastructural data determined between 24 and 48 h after imbibition and between 48 and 72 h after imbibition, the end of significant embryo and cotyledon protein mobilization, respectively, indicating more precocious storage protein mobilization in the axis than cotyledons. Moreover, storage protein mobilization in embryo and cotyledons occurred before the end of germination. Water soluble proteins were separated by sodium dodecyl sulfate polyacrylamide gel electrophoresis, producing 29 bands with molecular weights from 14 to 90 KDa. Embryo extract contained more proteins than cotyledon extract, contained seven characteristic bands, and showed a higher variability of the optical density trend than cotyledon.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The seed, leaf and root of Mucuna pruriens have been used in traditional medicine for treatments of various diseases. In Nigeria, the seed is used as oral prophylactics for snakebite. AIM OF THE STUDY To study the protective effects of Mucuna pruriens seed extract against the lethalities of various snake venoms. MATERIALS AND METHODS Rats were pre-treated with Mucuna pruriens seed extract and challenged with various snake venoms. The effectiveness of anti-Mucuna pruriens (anti-MPE) antibody to neutralize the lethalities of snake venoms was investigated by in vitro neutralization. RESULTS In rats, MPE pre-treatment conferred effective protection against lethality of Naja sputatrix venom and moderate protection against Calloselasma rhodostoma venom. Indirect ELISA and immunoblotting studies showed that there were extensive cross-reactions between anti-MPE IgG and venoms from many different genera of poisonous snakes, suggesting the involvement of immunological neutralization in the protective effect of MPE pre-treatment against snake venom poisoning. In vitro neutralization experiments showed that the anti-MPE antibodies effectively neutralized the lethalities of Asiatic cobra (Naja) venoms, but were not very effective against other venoms tested. CONCLUSIONS The anti-MPE antibodies could be used in the antiserum therapy of Asiatic cobra (Naja) bites.

Abstract
Previously, we reported the antisnake venom properties of a Mucuna pruriens seed extract (MPE) and tested its in vivo efficacy against Echis carinatus venom (EV) in short- (1 injection) and long-term (three weekly injections) treatments. The aim of the present study was to investigate plasma proteome changes associated with MPE treatments and identify proteins responsible for survival of envenomated mice (CHALLENGED mice). Six treatment groups were studied. Three control groups: one saline, one short-term and one long-term MPE treatment. One group received EV alone. Two test groups received EV with either a short-term or long-term MPE treatment (CHALLENGED mice). The plasma from each group was analysed by 2-DE/MALDI-TOF MS. The most significant changes with treatment were: albumin, haptoglobin, fibrinogen, serum amyloid A and serum amyloid P. Most of these changes were explained by EV effects on coagulation, inflammation and haemolysis. However, MPE treatments prevented the EV-induced elevation in HPT. Consequently, HPT levels were similar to controls in the plasma of CHALLENGED mice. The plasma of CHALLENGED mice showed substantial proteomic modifications. This suggests the mechanism of MPE protection involves the activation of counterbalancing processes to compensate for the imbalances caused by EV.

Abstract
The use of plants as medicine has been referred to since ancient peoples, perhaps as early as Neanderthal man. Plants are a source of many biologically active products and nowadays they are of great interest to the pharmaceutical industry. The study of how people of different culture use plants in particular ways has led to the discovery of important new medicines. In this work, we verify the possible activity of Musa paradisiaca L. (Musaceae) against the toxicity of snake venoms. Musa paradisiaca, an important source of food in the world, has also been reported to be popularly used as an anti-venom. Interaction of Musa paradisiaca extract (MsE) with snake venom proteins has been examined in this study. Phospholipase A2 (PLA2), myotoxic and hemorrhagic activities, including lethality in mice, induced by crotalidae venoms were significantly inhibited when different amounts of MsE were mixed with these venoms before assays. On the other hand, mice that received MsE and venoms without previous mixture or by separated routes were not protected against venom toxicity. Partial chemical characterization of MsE showed the presence of polyphenols and tannins and they are known to non-specifically inactivate proteins. We suggest that these compounds can be responsible for the in vitro inhibition of the toxic effects of snake venoms. In conclusion, according to our results, using mice as experimental model, MsE does not show protection against the toxic effects of snake venoms in vivo, but if was very effective when the experiments were done in vitro.

Abstract
In a previous paper we demonstrated that extracts of Mucuna pruriens seeds (MPE) protect mice against Echis carinatus venom (EV) by an immunological mechanism. In this paper we demonstrate that the MPE immunogen generating the antibody that cross-reacts with the venom proteins is a multiform glycoprotein (gpMuc) whose immunogenic properties mainly reside in its glycan-chains. The glycoprotein was purified from the protein extract of M. pruriens seeds using Concanavalin A affinity chromatography. Using 2-D gel electrophoresis it separated into seven isoforms having MWs in the range from 20.3 to 28.7 kDa and pIs from 4.8 to 6.5. N-terminal sequencing of these spots revealed close similarity since all of them contained the consensus sequence DDREPV-DT found in soybean Kunitz-type trypsin inhibitor. We suggest that gpMuc contains both N- and O-glycans. Mild alkaline treatment but not PNGase F led to loss of reactivity, indicating that O-glycans are probably involved in the antigenicity of gpMuc.

Abstract
Abstract Echis carinatus is considered to be one of the most dangerous snakes in the world because of its venom toxicity and high population densities in rural agriculture areas. However, little information is available on the pharmacological effects of venom from this snake on haemodynamy and vasculature smooth muscle contractility. The haemodynamic alterations induced by the intravenous administration of Echis carinatus venom was investigated in anaesthetized rats. Injection of several doses of venom (1, 3, 5, and 7 mu g kg (- 1)) decreased the arterial blood pressure. For instance, injection of 3 mu g kg(-1) of Echis carinatus venom reduced the mean arterial blood pressure from 107 +/- 4 to 71 +/- 4 mmHg (p < 0.05). Exposure of the rat isolated vas deferens preparations to Echis carinatus venom (1 mu g ml(-1)) significantly reduced the contractile responses to epinephrine (10 mu g ml(- 1)) without changing the response to KCl (50 mM). To investigate the effects of venom on peripheral vascular resistance, mesenteric bed was removed and perfused with Krebs solution. Addition of different concentrations of venom (1, 3, and 10 mu g ml(-1)) to the precontracted mesenteric bed (with phenylephrine, 5 x 10(- 4) M) decreased the contraction in a concentration-dependent manner. However, preincubation of mesenteric bed with atropine (0.1 mu M), L-NAME (10 (-5) M) or indomethacin (10(-5) M) prevented this effect of the venom. These results may suggest that the inhibitory effect of the venom on nonvascular smooth muscle (such as vas deferens) contractions is a postsynaptic phenomenon. Furthermore, it could be suggested that the cardiovascular effects of Echis carinatus venom are mediated through multiple mechanisms such as activation of muscarinic receptors as well as production of nitric oxide and prostaglandins.

Abstract
A phospholipase inhibitor (WSG) has been purified from Withania somnifera using gel-filtration and ion-exchange chromatographies. The WSG is an acidic glycoprotein. Its molecular mass as determined by SDS-PAGE was 27kDa. It neutralized the enzyme activity and pharmacological properties such as cytotoxicity, edema, and myotoxicity of a multi-toxic Indian cobra venom phospholipase (NNXIa-PLA) but failed to neutralize the neurotoxicity. The glycan part of the molecule does not appear to be involved in any of the pharmacological properties studied. The results suggest that the neutralization of the pharmacological effects of the toxic phospholipase is brought about by inhibition of the enzyme activity by formation of a complex between the WSG and the toxic phospholipase. We report the purification and characterization of a glycoprotein phospholipase A inhibitor from Withania somnifera, medicinal plant.
