This study investigated the possible anti-inflammatory, analgesic, and antipyretic effects of ethanolic extract of Pedalium murex Linn. fruits in selected experimental animal models. Anti-inflammatory activity of Pedalium murex Linn., with doses of 200 mg/kg and 400 mg/kg, p.o., was evaluated by Lambda-carrageenan induced paw oedema in Wistar albino rats; analgesic activity with doses of 280 mg/kg and 560 mg/kg, p.o., was evaluated by hot plate method and acetic acid induced writhing method in Swiss albino mice; and antipyretic activity with doses of 110 mg/kg and 220 mg/kg, p.o., was evaluated in New Zealand white rabbits by injecting gram -ve lipopolysaccharide obtained from E. coli. Results were analysed by one way ANOVA followed by Dunnet's multiple comparison test. Pedalium murex Linn. showed significant anti-inflammatory activity from 15 min to 180 min as compared to vehicle treated animals. It was comparable to diclofenac sodium at 180 min. The extract did not prolong the reaction time on hot plate method but significantly reduced the number of writhing after acetic acid administration. Also the extract did not show any antipyretic activity on lipopolysaccharide induced pyrexia. It is therefore concluded that the ethanolic extract of Pedalium murex Linn. fruits has an anti-inflammatory and peripheral analgesic effects.
Purpose: To investigate the anti-urolithiatic effect of cow urine ark (medicinal distilled cow urine) on ethylene glycol (EG) induced renal calculi. Materials and Methods: 36 male Wistar rats were randomly divided into 6 equal groups. Group I animals served as vehicle control and received distilled water for 28 days. Group II to VI animals received 1% v/v EG in distilled water for 28 days. Group II served as EG control. Group III and IV (preventive groups) received cow urine ark orally for 28 days in doses of 1 mL/kg and 2 mL/kg, respectively. Group V and VI (treatment groups) received 1 mL/kg and 2 mL/kg cow urine ark orally, respectively from 15th to 28th days. 24-hour urine samples were collected on day 0 and 28. Urine volume and oxalate levels were measured. On day 28, blood was collected for biochemical parameters. Animals were sacrificed and kidneys were harvested, weighed and histopathologically evaluated for calcium oxalate (CaOx) crystals. To calculate the percentage of inhibition of mineralization, simultaneous flow static in-vitro model was used. Results: EG significantly increased urine oxalate, serum creatinine, blood urea level; kidney weight and CaOx deposits. Provision of cow urine ark resulted in significantly lower levels of urine oxalate, serum creatinine, blood urea and CaOx depositions as compared to Group II. (p value < 0.05) It also significantly restored kidney weight. (p value < 0.05) Cow urine ark inhibited 40% and 35% crystallization of CaOx and calcium phosphate, respectively. Conclusion: Cow urine ark is effective in prevention and treatment of EG induced urolithiasis in Wistar rats.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
