Histopathologic changes in liver and kidney of male sprague dawley rats treated with extract of Cardiospermum halicacabum L.

In traditional medicine Cardiospermum halicacabum L. [Sapindeaceae] is used against various ailments such as rheumatism, nervous diseases, stiffness of the limbs and snakebite. Leaves are crushed and made into a tea, which aids itchy skin. Salted leaves are used as a poultice on swellings. Young leaves can be cooked and used as vegetables. The leaf juice has been used as a treatment for earache as well. In this study we evaluate acute toxicity [10, 50,100 and 500 mg/kg] and pathologic changes in esophagus, stomach, liver and kidney tissues with a magnifying glass and microscope in a row to mark changes to both morphological and histological in comparison to control with the treatment of ethyl acetate extract [dose of 40mg/kg] in male Sprague Dawley rats. The rats were divided into 4 groups consisting of 3 rats per group for acute toxicity and histopathological change. In conclusion, no lethality was observed in acute toxicity study for 7 days. The treatment of ethyl acetate extracts at 40 mg/kg did not show lethal toxicological changes as observed by histopathological examination in the kidney and liver tissues

Analgesic activity of various extracts of Holoptelea integrifolia [Roxb] Planch leaves

The various extracts of leaves Holoptelea integrifolia [Ulmaceae] were investigated for analgesic activity in mice by tail flick method. The fresh plant leaves of H. integrifolia were collected, dried, cleaned, weighed and chopped into small pieces and percolated in ethanol. The fractionation of crude extract, followed by the addition of distilled water, ethyl acetate and n-butanol to an aqueous portion of each solvent, to obtain the dried masses of each four layers. Qualitative chemical examination indicates the presence of secondary metabolites such as alkaloids, flavones, phenol, steroids, tannins and triterpenoids. No acute oral toxicity was observed and extracts considered being safe at the dose of 50-2000 mg/kg body weight. At the dose of 500 mg/kg various extracts of leaves of H. integrifolia were found statistically significant [P<0.05]. A maximum effect was established at 150 min, after drug administration. Diclofenace sodium used as a standard
