The antidiarrhoeal effects of the methanolic extract of Rhus javanica ripen fruits (MERJ) were investigated by employing four experimental models of diarrhoea in Swiss albino mice. MERJ treated mice, showed significant reduction in the faecal output and protected them from castor oil-induced diarrhoea. The extract also reduced the intestinal fluid secretion induced by MgSO4 and gastrointestinal motility after charcoal meal administration in the albino mice. No mortality and visible signs of general weakness was observed in the mice following the test extract administration up to 2000 mg/kg dose. [Copyright &y& Elsevier]

Abstract: Aim of this study: Adhatoda vasica Nees has been commonly used in the indigenous system of medicine of Naga tribes in India for curing intestinal worm infections. In this study the anticestodal efficacy of Adhatoda vasica leaf extract was evaluated using Hymenolepis diminuta-rat experimental model. Materials and methods: The anticestodal efficacy of leaf extract was determined by monitoring the eggs per gram (EPG) of faeces counts and percentage worm recovery rates following treatment with methanol leaf extract of this plant to different groups of rats harbouring immature and mature Hymenolepis diminuta infections. Results: The result indicated 800mg/kg double dose of extract has profound efficacy against mature worms, where the EPG count was reduced by 79.57% and percentage worm recovery rate by 16.60%. These effects were better than treatment with 5mg/kg single dose of praziquantel, the standard drug. In case of efficacy against immature worms, the extract showed a significant reduction in worm recovery rate (from 100% in control to 20.00% at 800mg/kg dose of extract). Conclusion: The study shows that the leaf extract of Adhatoda vasica possesses significant anticestodal efficacy and supports its use in the folk medicine. [Copyright &y& Elsevier]

Abstract: Use of Strobilanthes discolor T. Anders leaves in the treatment of intestinal worm infections is a common ethnobotanical practice in the Naga tribes of north-eastern part of India. In the present communication the anticestodal efficacy of Strobilanthes discolor leaf extract was investigated using Hymenolepis diminuta—rat experimental model. The effects of leaf extract were adjudged by monitoring the eggs per gram of faeces (EPG) counts and percentage worm recovery rates following treatment with methanol leaf extract of this plant to different groups of rats harbouring Hymenolepis diminuta infections. The leaf extract showed significant reductions in EPG counts as well as in recovery of surviving worms at autopsy. A notable result of the extract''s efficacy was observed against the larval stages of parasite, where no single worm was recovered at its 800mg/kg dose administered twice daily for 3 days. Effects of plant extract on adult stages were almost comparable with that of a standard drug, Praziquantel. The study suggests that the leaf extract of Strobilanthes discolor possesses significant anticestodal activity and supports its use in the folk medicine. [Copyright &y& Elsevier]
