An attempt on individual toxicity of lead nitrate and barium chloride on the Indian major carps, catla, rohu and mrigal was carried out as they are the natural inhabitants of the perennial rivers network of India and neighbouring countries where pollutants are becoming a major stress factor for these commercially important edible fishes. For all the three major carps, the 96 hr LC50 and Sub Lethal Concentration (SLC) were in the order of Lead nitrate > Barium chloride. In the individual toxicity studies, the three carps exhibited a decreasing trend in total proteins and total lipids in all the test tissues but liver alone showed an increasing trend with reference to carbohydrate content.Keywords

Evaluating the toxic effect of an organochlorine pesticide, endosulfan and heavy metal lead on the fingerlings of Indian carp Labeo rohita was the prime aim. Individual and successive exposure of the two toxicants was assessed. 96 hr LC50 studies on pesticide and heavy metal resulted in the sub lethal concentration of 4 ppm and 87.5 ppm respectively. Post exposure estimation of nutritional parameters; total proteins, total carbohydrates and total lipids on muscle, liver, brain and kidney of the fish was done for individual toxicants. The impairment of metabolism was found to be more on lead exposure compared to endosulfan. Successive exposure study of the two environmental stressors was carried out to consider the combination effect on the nutritional status of the test fish.Keywords

Preparation and Standardization of Ayurvedic compound is vital to assure therapeutic efficacy and safety. Deepavali avaleha is a polyherbal Ayurvedic formulation consisting of eleven drugs used for Digestive, Appetizer, Carminative, Anti Flatulent, Antispasmodic, Improving digestive fire, Cleansing of micro channels of the body. The present study was aimed that to Prepare and Standardize the Traditional Polyherbal Avaleha formulation with respect to phyto-chemical screening, thin layer chromatography (TLC) and High performance thin layer chromatography (HPTLC) finger printing. Ingredients of sample were powdered separately and subjected for detailed Macroscopical studies, Phyto-Chemical screening, Powder microscopy and the powder drugs are combined in prescribed proportion and analyzed by using TLC and HPTLC as per standard procedures. The tests results obtained like HPTLC fingerprint profile would serve as diagnostic parameters for the identity of this poly herbal formulation. The results obtained may be considered as tools for assistance to the regulatory authorities, scientific organizations and manufacturers for developing standard formulation of great efficacy.Keywords

The PMMA and PVDF thin films were synthesized by solution casting process. The structural, spectroscopic, and morphological attributes of both the interface and surface of the film have been investigated. The structural properties of pristine PMMA and PVDF thin film were studied by XRD. The XRD spectra showed the detailed state of order and disorder of the system. From the XRD studies amorphous nature as well as the crystallanity (semi crystalline nature) of the polymer thin film were identified. SEM showed the surface morphology of the pristine PMMA and PVDF thin film. From the SEM image the size and the porous nature of the thin film were estimated. The UV showed the absorption characteristics of PMMA and PVDF thin films. From the UV-Visible spectra, we determined the direct and indirect optical energy gap of pristine PMMA and PVDF polymer samples by Devi's and Mott formula and Tauc's Expression. To the best of our knowledge, the direct and indirect energy gap in pristine PMMA and PVDF polymer thin films have been observed for the first time as no such report was found in literature survey.Keywords
