The current study is to develop the acute and sub-acute toxicity profile of some ayurvedic Bhasma and un-derstand the side effects due to the presence of heavy metals. Chandraprabha vati pill were weighed, powdery and suspended in water had made into liquid formulation. The animals were classified and treated with the doses of Chandraprabha vati (50and five hundred mg/kg) in rat. The dose was calculat-ed by extrapolating the equivalent human dose (1 and ten times) and was administered orally between ten and eleven after median daily for twenty eight days, during alylin a very volume not exceeding one ml/100 g rat weight. Blood was collected on seven, fourteen and twenty eight days, later they were sacri-ficed for histopathological studies.

SummaryUbiquin (oligo-3-(N-methylmorpholinium)-l,2-propylene oxide chloride) is a stable, water soluble, active heparin antagonist producing prompt neutralization when administered in a 1:1 ratio to rats and dogs. Initial studies indicate that it is devoid of any effect on coagulation per se; nor are there any obvious side effects manifested during the process of neutralization. The acute toxicity is less than that of other compounds in use: toluidine blue, protamine and hexadimethrine.

Important Medicinal Plant

Abstract Drug induced nephrotoxicity is one of the most common causes of renal failure. Gentamicin belongs to aminoglycosides, which elicit nephrotoxic potential. Natural antioxidants from plants demonstrate a number of biotherapeutic activities. Coriander is an important medicinal plant known for its hepatoprotective, diuretic, carminative, digestive and antihelminthic potential. This study was designed to investigate whether the extract of Coriandrum sativum ameliorates the nephrotoxicity induced by gentamicin in rats. Dried coriander powder was coarsely grinded and subjected to defatting by petroleum ether and further with ethyl acetate. The extract was filtered and subjected to phytochemical and phytoanalytical studies. Acute toxicity in Wistar rats was determined by the OECD Guideline (423). Animals were divided into four groups. The first group served as positive control, while the second group was toxic control (gentamicin treated). The third and fourth group were treated with the extract (200 and 400 mg/kg gentamicin). After 8 days, the animals were sacrificed and biochemical and histopathological studies were carried out. Phytochemical screening of the extract demonstrated Coriandrum sativum to be rich in flavonoids, polyphenolics and alkaloids. Results of acute toxicity suggested the use of 200 mg/kg and 400 mg/kg for Coriandrum sativum in the study. Coriandrum sativum extract at the dose of 400 mg/kg significantly (p<0.01) decreased creatinine levels in the animals, along with a decrease in serum urea and blood urea nitrogen. Treatment with Coriandrum sativum extract ameliorated renal histological lesions. It is concluded that Coriandrum sativum is a potential source of nephroprotective phytochemical activity, with flavonoids and polyphenols as the major components.

The effect of a new analgesic compound ( propoxyphene, acetaminophen, caffeine, hydroxyzine) was investigated in a single-blind study comparing it with plain acetaminophen administered to forty patients with tension headache. For the study, patients were assigned to one of two groups of twenty each. Starting dose for each group was one to two tablets followed by one tablet every four to six hours. The results show that 90% clinical success was obtained with the analgesic compound, while a 45% success was obtained with plain acetaminophen. This is a statistically significant difference. Side-effects observed with analgesic compound were primarily drowsiness and dizziness of mild intensity; acetaminophen caused gastro-intestinal alterations ( nausea, vomiting) and dizziness of greater severity. Therapy was withdrawn in 20% of patients taking acetaminophen because of side-effects. The dosage of analgesic compound required to control each episode of tension headache way smaller than that of acetaminophen. These results can be explained by a possible potentiation of pharmacological activity of the compound's components. It can be concluded that the analgesic compound is a new and effective combination for the symptomatic treatment of tension headache.

Vitex Doniana

The fresh fruits of Vitex doniana sweet were collected from several randomly selected trees in a farm site in Uromi metropolis, Esan North-East Local Government Area of Edo state and then processed into an extract in form of syrup. The proximate composition and acute toxicity profile of Vitex doniana sweet fruit were investigated to ascertain its safety and nutritional capability. Analysis of the fruit showed it to be a highly nutritious food containing moisture of about, 9.90%, ash content: 21.5%, fat: 0.75%, fiber: Not detected (ND), protein: 0.006% and carbohydrate: 67.84%. Twenty mice were randomized based on body weight into five groups of four mice each. Three mice in each group were given syrup volumes of 100, 200, 300, 400 and 500 mg/ml respectively, corresponding to 1000, 2000, 3000, 4000 and 5000 mg/kg doses. In contrast, mice in the control group received potable water (10 mL/kg). The mice in all the groups were observed closely for mortality, toxicity signs and abnormalities in gross behaviour at 15 min, 30 min, 1, 2, 4 and 8 h, and then daily for 14 days. Based on the model used, the fruit was acutely safe in mice, since no death was observed within 24 hours after oral treatment and on extrapolation gave a high predictive value in humans. The LD50 value of black plum fruit was also found to be greater than 5000 mg/kg. Therefore, Vitex doniana fruit should be considered a source of edible syrup bearing in mind the safety, quantity and variety of nutrients it contains.

Since the discovery of cytokines, much effort has been put forth to achieve therapeutic translation for treatment of various diseases, including cancer and autoimmune diseases. Despite these efforts, very few cytokines have cleared regulatory approval, and those that were approved are not commonly used due to their challenging toxicity profile and/or limited therapeutic efficacy. The main limitation in translation has been that wild-type cytokines have unfavorable pharmacokinetic and pharmacodynamic profiles, either eliciting unwanted systemic side effects or insufficient residence in secondary lymphoid organs. In this review, we address protein engineering approaches that have been applied to both pro- and anti-inflammatory cytokines to enhance their therapeutic indices, and we highlight diseases in which administration of engineered cytokines is especially relevant.

This study examines the prospects for using Hydra viridissima toxicity test 96-h LC50, served as a model invertebrate, Lactuca sativa L. was applied for seeds toxicity test (120-h IC50) and a model plant for an acute toxicity assessment of heavy metals content in water. The heavy metals used to assess the acute toxicity of the water utilized for agricultural irrigation in arid regions includes cadmium (CdCl2.2H2O), chromium (K2Cr2O7), zinc (ZnSO4. 7H2O), and boron (H3BO3). A grading of the substances was conducted, and it was found that the toxicity levels for H. viridissima and L. sativa were, with the least harmful first: B < Cr < Zn < Cd and Zn < B < Cr < Cd, respectively. Results indicate that H. viridissima was a more sensitive indicator of toxicity for all of the evaluated substances. However, L. sativa could also be used successfully to rank toxicants in order of their potential hazards.
