Quantification of Stigmasterol in Successive Extracts of Clerodendrum Serratum, Poly Herbal Formulation By Hptlc Method And In-vitro Anti - Oxidant Activity Studies.

The aim of the present study is to carry out the quantification of Clerodendrum serratum containing poly herbal formulations by HPTLC and to study the invitro anti-oxidant activity of nitric oxide scavenging activity of the roots of Clerodendrum serratum.The rhizome part of Clerodendrum serratum has been selected, dried, powdered and extracted with petroleum ether, chloroform, ethyl acetate and methanol successively by continuous hot percolation method using soxhlet apparatus. Preliminary phytochemical screening of the successive extracts showed the presence of chemical constituents like triterpenoids, flavonoids, alkaloids, tannins, glycosides and sesquiterpenes. The Rf value of stigmasterol was found to be 0.80 ± 0.02.The developed methods were validated as per ICH guidelines. The LOD and LOQ was found to be 100 and 300 ng/spot respectively for HPTLC. The anti-oxidant activity was highest in petroleum ether extract when compared to the other extracts by using ascorbic acid as control. This shows that the polyherbal formulation containing stigmasterol has medicinal value and that it may be utillised for its anti-oxidant properties.

Quantitative Estimation of Lupeol in Polyherbal Formulation And Successive Extracts of Crataeva Nurvala and their In-Vitro Anti-Inflammatory Activity Study.

The aim of the present study is to carry out the quantitative estimation of lupeol in poly herbal formulations by HPTLC and to study the invitro antiinflammatory activity study of Crataeva nurvala bark. The bark of Crataeva nurvala was selected, dried, powdered and extracted with petroleum ether, diethyl amine and methanol successively by continuous hot percolation method using soxhlet apparatus. Preliminary phytochemical screening of the successive extracts showed the presence of chemical constituents like triterpenoids, flavonoids, alkaloids, tannins, glycosides and sesquiterpenes. The Rf value of lupeol was found to be 0.49 ± 0.03.The developed methods were validated as per ICH guidelines. The LOD and LOQ was found to be 50 and 300ng/spot respectively for HPTLC. The anti-inflammatory activity was highest in petroleum ether extract when compared to other extracts when evaluated by using ibuprofen as the control. This shows that the polyherbal formulation and medicinal plants containing lupeol as the active constituent has medicinal value and that they may be utillised for their anti-inflammatory properties.

Multiple focal nodular hyperplasia, an incidental finding on autopsy.

Focal nodular hyperplasia (FNH) is a benign condition of the liver often discovered incidentally on radiological investigation. Although FNH is a well-described lesion in the literature considerable diagnostic problems regarding this entity still remains. We report a case of multiple FNH in a 23-year-old male patient detected as an incidental finding in autopsy. On gross examination FNH was not suspected because of the multiple lesions and the lack of central scar which is characteristically described in FNH. The diagnosis was established on histopathology after examination of multiple sections of the lesions.

Study of Serum Cholinesterase levels in fish Clarias batrachus (Linn.) exposed to pesticides carbaryl and phorate.

Study of the Serum Cholinesterase levels (SchE) in the freshwater catfish Clarias batrachus when exposed to sub lethal dose of pesticides phorate and carbamate, was attempted in this paper. SchE levels decreased in the fish exposed to both the pesticides, the depletion being more pronounced with phorate. These results can be due to impairment of nervous system, liver damage as well as myocardial infarction. Similar findings were not only reported in experimental organisms but also found in human beings working in agricultural fields and pesticide manufacturing plants. Hence it is imperative that suitable occupational health and preventive measures need to be undertaken.

Effect of pesticides carbaryl and phorate on serum cholesterol level in fish, Clarias batrachus (Linn).

Freshwater edible catfish Clarias batrachus (Linn.) was treated with sublethal concentration of two different groups of pesticides- carbaryl, a carbamate and phorate, an organophosphate for 24 ,72 ,120 and 168 h. The disorders of lipid metabolism were observed in serum. Cholesterol levels in the serum decreased significantly throughout the exposure period with both the pesticides. These results indicate one significant manifestation of the toxic response from the fish under the stress of pesticide exposure.

Pesticide induced alterations of non-protein nitrogenous constituents in the serum of a fresh water cat fish, Clarias batrachus (Linn.).

A freshwater cat fish was exposed to sublethal concentrations of two pesticides--carbaryl, a carbamate and phorate, an organophosphorus pesticide for 24, 72, 120 and 168 hr. The alterations in the serum profile of non protein nitrogen compounds demonstrated an increase in urea, uric acid and creatinine throughout the experimental period.
