Abstract

The effects of sub-lethal concentration of nickel on the biochemical composition such as glycogen, protein, cholesterol, lactic acid, pyruvic acid in gills, hepatopancreas, muscles and sugar contents along with haemolymph in female crab, Scylla serrata procured form local fish market in Mumbai (Sassoon Dock) were studied. The female crabs were exposed to sub-lethal dose of nickel LC and LC were 200ppm and 500ppm 0 50 respectively. Among the control set the glycogen contents were found to be the highest in muscles (44.616±0.225 mg/gm wt); protein contents were maximum in gills (66.5232±0.170 mf/gm wt); cholesterol contents were highest in ovary (2.009±0.006 mg/gm wt). The sub-lethal dose of nickel caused decline in the contents of glycogen (1.030±0.0141), protein (11.299±0.055), cholesterol (1.373±0.008) and pyruvic acid (0.440±0.195) in most of the tissues studied. The lactic acid contents increased in all the tissues studied in response to the exposure of nickel. The sugar and lactic acid contents in haemolymph were elevated as a result of exposure whereas the contents of protein, cholesterol and pyruvic acid in haemolymph declined due to the sub-lethal exposure in female crabs.

Abstract

This research paper reports on the effects of exposure of green mussel to sub lethal concentrations of cadmium and zinc on GOT, GPT, ACP and ALP activities in the tissues of mantle, gill, hepatopancreas, adductor muscle, siphon, foot and gonad of Perna viridis. Exposure of sub lethal concentration of cadmium for 15 days resulted in the increase of GOT activity in all the tissues and was found to be the maximum in mantle and gonad but declined in hepatopancreas, siphon and foot. 30 days exposure of cadmium caused over all increase in GOT activity but the maximum was found to be in gonad although hepatopancreas and mantle showed higher levels of this activity. The GOT activity increased in all the tissues except in adductor muscle and the maximum in hepatopancreas and gonad as a result of exposure to lower concentration of zinc. Higher concentration of zinc for 30 days resulted in the increase in the activity in all the tissues but being higher in hepatopancreas, gill and gonad. GPT activity due to exposure to lower concentration of cadmium declined in mantle, adductor muscle, siphon, gill and gonad but it showed gentle rise in case of hepatopancreas and foot after 30 days of exposure. The exposure of lower concentration of zinc caused decline in GPT activity in mantle, adductor muscle, siphon, foot and gonad while in gill it increased. The ACP activity increased in all the tissues except in adductor and gonad during 15 days exposure to cadmium while exposure to zinc brought about elevation in all the tissues except gill. The exposure for 30 days resulted in decline in ACP activity in hepatopancreas, mantle and foot. 15 days exposure to cadmium enhanced the ALP activity in all the tissues but not in foot where as 30 days exposure resulted in decline in ALP activity in mantle, gill and adductor muscle. Exposure of zinc caused gradual increase in ALP activity in all the tissues studied. Thus, there is a possibility that Perna viridis can act as an indicator of pollutant contamination due to cadmium and zinc.

Abstract

The etoposide (VP-16) is in use as one of the regimen in cyclical chemotherapeutic treatment for several kind of cancer like testicular cancer, small cell bronchogenic carcinoma, malignant lymphoma. Etoposide (VP-16), an anticancer drug, 1mg/kg/day was administered intramuscular for two months. The animals were anaesthetized with ether and excised testis and epididymis for electron microscopic studies. The testicular tissue revealed that the severe atrophic changes, suggestive arrest at the germinal cell level as well as at the Sertoli cell level. The cellular integrity of all is drastically reduced with a severe nuclear alteration also taking place. The observations showed that damage of early spermatogonia and the later stages of spermatogenesis were completely eliminated. The leydig cells revealed state of work induced hypertrophy as is evident from the secretory activity but the organelles show a condition of extreme overburdened state just prior to state of collapse. In conclusion our result shows that adverse effect of etoposide on testis especially on spermatogonia can be distinguished after two months treatment. The electron microscopic features show that it leads towards the male fertility disorder.
