Objective: The objective of this study is to evaluate a meticulous pharmacognostic cram is to supplement constructive information with regard to its identification, characterization, and standardization of endemic and endangered medicinal climber var. and also screening the antibacterial activity of this climber.

Materials And Methods: The morphological characters of study plant, microscopic examination of leaf powder, anatomy of young stem, physicochemical analysis of plant powder, extractive values, phytochemical analysis, powder with different chemical reagents, fluorescence analysis of plant powder, and other World Health Organization (WHO) recommended for standardization were analyzed.

First occurrence of (Bleeker, 1857) (Isopoda: Cirolanidae) on coral reef fishes along the Tuticorin coastal water, Gulf of Mannar.

Isopod Parasites are considered as a major threat to the fishing industry, due to rigorous disease outbreaks. The parasites from the two economically important reef fish family Lutjanidae and Serranidae are analyzed i.e.

First record of sp. an ectoparasitic isopod isolated from the coral reef fish, collected from the Gulf of Mannar region, southeast coast of India.

An ectoparasitic isopod, sp. was found in the Gill chambers of collected from the Gulf of Mannar region, Southeast coast of India. The present study signifies the new record of sp.

Isolation and identification of bacteria from marine market fish Scomberomorus guttatus (Bloch and Schneider, 1801) from Madurai district, Tamil Nadu, India.

The present study was conducted to evaluate the hygienic quality and freshness of fish Indo-pacific King Mackerel "Scomberomorus guttatus" through the investigation of the occurrence of bacteria which is an indicator for fish quality. Fishes were collected every fortnight from Madurai fish market on monthly twice of January 2014 to March 2014. Skin surface of the fish was examined.

Preliminary phytochemical studies on solanum surattense burm.f. Seeds.

Solanum surattense Burm.f. has been largely used in the indigenous system of medicine.

3-Cyclopropyl-1,2,4-triazolo[3,4-b]benzothiazole monohydrate.

The title structure, C11H9N3S.H2O, contains two crystallographically independent molecules, each consisting of a 1,2,4-triazolo[3,4-b]benzothiazole-fused ring fragment substituted with a cyclopropyl ring, and a water molecule. The geometry of both molecules differs slightly.

Characterization of ribonuclease P isolated from rat liver cytosol.

Rat liver ribonuclease P was isolated from a cytosolic fraction and shown to have optimal activity in the presence of 1 mM MgCl2 and 150-200 mM KCl using Escherchia coli pre-tRNA(Tyr) as substrate. In cesium sulfate isopycnic density gradients, the enzyme had a buoyant density of 1.36 g/ml, indicating that it is a ribonucleoprotein complex.

Effect of DL alpha-lipoic acid on some carbohydrate metabolising enzymes in stone forming rats.

DL alpha-lipoic acid has been shown to prevent the induced precipitation of calcium oxalate crystals in the renal tissues of laboratory animals. The acid seems to have a profound influence on carbohydrate metabolism in diabetic rats. Here the effect of alpha-lipoic acid was studied on certain key carbohydrate metabolising enzymes in the tissues of calcium oxalate stone forming rats administered with glycollate as oxalate precursor.

Synergistic interaction of a protease and protease inhibitors from Russell's viper (Vipera russelli) venom.

An acidic proteolytic enzyme, RVVX, was purified from Vipera russelli venom by successive chromatography on CM-Sephadex C-25, DEAE-cellulose and Sephadex G-100 columns. RVVX is a glycoprotein with a mol. wt of 79,000.

Dissociation of catalytic activity and neurotoxicity of a basic phospholipase A2 from Russell's viper (Vipera russelli) venom.

A neurotoxic phospholipase A2, VRV PL-V was purified from Vipera russelli venom in a single step by CM-Sephadex C-25 column chromatography. VRV PL-V is a basic PLA2 with a mol. wt of approximately 10,000.

Geographical variation in India in the composition and lethal potency of Russell's viper (Vipera russelli) venom.

Venom samples of Russell's viper (Vipera russelli) from three localities in India were analysed for their composition and toxicity. Column chromatographic fractionation on CM-Sephadex C-25 showed the absence of three fractions in the venom samples of southern India compared with the samples from northern and western India. The SDS-PAGE pattern of southern Indian venom samples also showed lack of three protein bands corresponding to molecular weights of 66,000, 39,000 and 9000.
