Acute Changes

Objective: The fundamental reason for this examination was to look at the acute and subchronic toxicity studies of chloroform and methanol extracts of Barleria buxifolia Linn. (Acanthaceae) on creature models according to the OECD rules 407 and 425, respectively. Methods: In acute oral toxicity, study a single oral dosages of 5000 mg/kg body weight of chloroform and methanol extracts was given individually to rats and watched them for 2 weeks for the discovery of acute changes and for its mortality any. During acute oral toxicity study period, no mortality was seen without any signs of intense changes. Further, it was executed the subchronic toxicity of extracts. Barleria buxifolia extracts (chloroform and methanol) were independently given every day at dosages of 250 and 500 mg/kg body weight for 90 days to recognize the progressions any at subchronic poisonousness levels. Towards the finish of the experimentation the serum tests of trail creatures were gathered and watched for any progressions in haematological, biochemical and histopathological boundaries Results: All parameters of treated group were shown unaltered changes throughout the study period when compared with that of normal group. The outcomes propose that the oral organization of chloroform and methanol extracts of Barleria buxifolia did not raise any huge poisonous impacts when contrasted with that of control animals. Conclusion: Hence, the extracts may be safe for therapeutic use and as an alternative system of medicine.

Aim: To evaluate the antidiarrhoea effect of hydromethanolic leave extract of I. asarifolia (HLEIA) on castor oil-induced diarrhea. Place and Duration of Study: Department of Biochemistry, Faculty of Life sciences, Kebbi State University of Science and Technology, Aliero, Kebbi state, Nigeria. P.M.B.1144. Kebbi State. Nigeria, between February 2015 and September 2016. Methodology: In a continuous effort to search for bioactive agents from medicinal plants, the antidiarrhoea activity of I. asarifolia was investigated. The effect of hydromethanolic leave extract of I. asarifolia (HLEIA) on castor oil-induced diarrhoea, gastrointestinal transit and intestinal fluid accumulation (enteropooling) were assessed in albino rats. Qualitative phytochemical analysis was carried out using standard procedures while acute oral toxicity studies was determined using the staircase method. Results: The phytochemical analysis showed the presence of alkaloid, terpenoid, tannin, saponin, phenols. The LD50 was estimated to be greater than 3000 mg/kg since there was no mortality recorded after 14 days of acute oral toxicity studies. Sub-chronic administration of graded doses (150 – 600 mg/kg) of HLEIA significantly (p<0.05) reduced diarrhoea episodes, decreased gastro intestinal movement and inhibited intestinal fluid accumulation compared to the control. The antidiarrhoea effect of treated group (600 mg/kg ) was comparable to that of the standard drug Loperamide. Conclusion: The findings of the present study scientifically validate the use of I. asarifolia in the treatment of diarrhoea.

Grewia Tenax

Aim: To screen Kenyan Grewia tenax root extract phytochemicals and correlate the attribute fertility enhancing effects and safety in female albino rats. Study Design: An experimental study design was used. Place and Duration of Study: The phytochemical studies were done at Jomo Kenyatta University of Agriculture and Technology (JKUAT), Department of Botany Laboratory, while acute oral toxicity studies were done at the Department of Veterinary Anatomy and Physiology, University of Nairobi (UON) animal house. The study was done during the month of March to June 2019. Methodology: Grewia tenax was harvested with the help of a plant taxonomist. The roots were chopped into small pieces and dried under shade for three weeks. They were then ground into powder. Organic extracts were prepared by sequential extraction (petroleum ether, dichloromethane (DCM), ethyl acetate and methanol), by use of cold maceration. Aqueous extracts were obtained by hot maceration. Phytochemical screening of extracts was done by standard phytochemical procedures. A total of 12 female albino rats were used in acute oral toxicity studies as per OECD 423 guidelines. Results: Methanol extract had the highest composition of phytochemicals, i.e. alkaloids, flavonoids, saponins, sterols, terpenes and cardiac glycosides. Aqueous and DCM extracts showed presence of alkaloids, saponins and cardiac glycosides, while petroleum ether and ethyl acetate extracts showed presence of alkaloids and cardiac glycosides. Steroids and tannins were absent in all extracts. Flavonoids, alkaloids and terpenes are fertility enhancing compounds due to their antioxidant and radical scavenging properties. Flavonoids, alkaloids and glycosides improve fertility by inducing ovarian steroidogenesis and folliculogenesis. In the acute oral toxicity study, there were no adverse effects at 5000 mg/kg extract administration. Conclusion: Kenyan Grewia tenax root extract has phytochemicals postulated to enhance fertility and is orally safe. These findings may require further verification using in vivo studies.

Abstract Objectives Madhulai Manappagu – a well-known sastric and widely prescribed Siddha herbal syrup formulation indicated for treating Veluppu Noi (Anaemia especially Iron deficiency Anaemia) has been in day today practice in Tamil Nadu for a quite longer decades. The syrup is a herbal preparation which has a sweet pleasant odour and a palatable taste, contain the juice of pomegranate (Punica granatum L.) as the main ingredient. Though the formulation is a fruit juice, the safety profile of the syrup is not established and is being marketed without toxicological evaluation. The study is aimed at ascertaining the acute and sub-acute toxicity assessment of Madhulai Manappagu in Wistar Albino rats. Methods The acute and sub-acute (28day repeated oral) toxicity studies were performed as per the guidelines mentioned in the Organization for Economic Cooperation and Development (OECD) 423 (adopted on December 2001) and TG 407 (adopted on October 2008) with slight modifications respectively. For acute toxicity study, three female rats were randomly selected as control; three female rats were randomly selected and were administered a single dose of 5,000 mg/kg body weight per oral route. For sub-acute (28day repeated oral) toxicity studies, three doses of test drug MM of 500 mg/kg/day (low dose), 750 mg/kg/day (intermittent dose) and 1,000 mg/kg/day (high dose) were selected for administration. Both sexes of Wistar Albino rats were randomized into four groups of 10 animals each (five males, five females). Group I was kept as control group. Group II, III and IV served as low, intermittent and high doses of MM respectively. Animals were observed for mortality, morbidity, body weight changes, feed and water intake. Haematology, clinical biochemistry, electrolytes, gross pathology, relative organ weight and histopathological examination were performed. Results In the acute toxicity study, rats showed no toxicological signs on behavior, gross pathology and body weight of rats when treated with a single dose of 5,000 mg/kg body weight per oral route. In the subacute (28 days repeated oral) toxicity study, rats have showed no significant changes on behavior, gross pathology, body weight, and hematological and biochemical parameters when treated with Madhulai Manappagu in three different doses. Conclusions The toxicity studies which include both acute and 28 days repeated (subacute) oral toxicity studies, revealed no observed adverse effect level (NOAEL) of Madhulai Manappagu in animals. Thus the safety of the drug in human usage was ensured.

Thiol Functionalization

Objective: In the present study, thiol-functionalization of psyllium seed polysaccharide (PSY) was cross-linked with thioglycolic acid by esterification in an attempt to reveal the mucoadhesive properties of thiolated psyllium seed polysaccharide (TPSY).Methods: The crosslinking was carried out by the microwave-assisted method. A simplex centroid design was employed to systematically study the mucoadhesive strength, mucoadhesive retention time and drug release profile. Comparative evaluation of carbopol-based ciprofloxacin hydrochloride (HCl) tablets containing PSY and TPSY was carried out. Acute oral toxicity studies and repeated oral toxicity for TPSY were also conducted.Results: Thiol-functionalization was confirmed by-SH stretch in Fourier Transform infra-red spectra at 2353 cm-1. Thiolation was observed in thiolated PSY (TPSY) by a change in the surface morphology of psyllium from fibrous to granular and resulted in 82 %swelling in deionized water. TPSY was found to contain 102.35 mmol of thiol groups/g as determined by the Ellman’s method. The percent increase in mucoadhesive strength of TPSY was found to be 50.31 % as compared to PSY and 128.30 % as compared to carbopol. The percent increase in mucoadhesive retention time of TPSY was found to be 110 % as compared to PSY and 50 % as compared to carbopol.Conclusion: Mucoadhesion strength and mucoadhesive retention time were greater of tablets containing a higher amount of TPSY. Further, the acute oral toxicity studies and repeated oral toxicity for TPSY proved it as non-toxic and hence safe for human use.
