Zinc Exposure

Present study was carried out to evaluate the changes in organic reserves of kidney, liver, gill and muscles of Clarias batrachus exposed to sublethal concentrations of zinc sulphate in water for a period of 15,30 and 45 days. Four groups of twenty five fish were subjected to 0 (control), 10, 20 and 30 mg/L of zinc sulphate. The sub-chronic exposure of Clarias batrachus to sub-lethal concentration of Zinc sulphate showed a decline in glycogen, total proteins, cholesterol and total lipids in all these tissues. The levels of these organic reserves alter simultaneously with an increase in dose and duration of zinc exposure.

The present investigation deals with the prevalence of infection of cestode, Pseudoinverta oraiensis19 parasitizing Clarias batrachus from Bundelkhand Region (U.P.) India. The studies were recorded from different sampling stations of Bundelkhand region of Uttar Pradesh. For this study 360 fresh water fish, Clarias batrachus were examined. The incidence of infection, monsoon season (17.50%) followed by winter season (20.00%) whereas high in summer season (30.00%).

Medicinal plants plays a significant role in the pharmaceutical industry. In present scenario, the need is to explore, identify and utilize this new medicinal plant on one hand and, on the other, to help conserve the existing but threatened species of rare medicinal plant.This present research work was carry out for the first time in South India to analyse and estimate the biochemical profiles of various extracts of fresh parts of Gnaphalium polycaulon pers., plant. The biochemical composition such as total carbohydrates, total proteins, total lipids, total phenols, cholesterol, total chlorophylls and reducing sugar, sterols were estimated using the standard procedure in fresh plant material.The biochemical analysis of Gnaphalium polycaulon plant showed the presence of various phytochemicals. The results of the present study supplement the usage of the studied plant which possesses several bioactive compounds and used as food and also as medicine.The results of present studies demonstrated that Gnaphalium polycaulon plant could be a sourceof valuable information and a guideline for the scientists, researchers in India and also all over the world

Investigation results are reported on immunobiochemical indices in carassius carassius at a chronic exposure to sub-lethal Zink ions concentrations. In blood serum and liver, the following characteristics were investigated: antimicrobial properties, proportion of immune- deficient animals, content of non specific immune complexes, common lipids level, content of lipids peroxidation products and antioxidant activity. The relation between magnitudes of indices under investigation in fishes and the duration of their presence under experimental conditions is shown.

AbstractAt two natural volcanic seeps in Papua New Guinea, the partial pressure of carbon dioxide (pCO2) in the seawater is consistent with projections for 2100. Here, the cover of massive scleractinian corals Porites spp. is twice as high at elevated compared with ambient pCO2, while that of branching corals such as Acropora millepora is greater than twofold reduced. To assess the underlying mechanisms for such community shifts under long-term exposure to elevated pCO2, biochemical parameters related to tissue biomass, energy storage, pigmentation, cell protection, and cell damage were compared between Porites spp. and A. millepora from control (mean pHtotal = 8.1, pCO2 = 323 µatm) and CO2 seep sites (mean pHtotal = 7.8, pCO2 = 803 µatm) each at two reefs. In Porites spp., only one of the biochemical parameters investigated (the ratio of photoprotective to light-harvesting pigments) responded to pCO2, while tissue biomass, total lipids, total proteins, and some pigments differed between the two reefs, possibly reflecting differences in food availability. Furthermore, some fatty acids showed pCO2 –reef interactions. In A. millepora, most pigments investigated were reduced at elevated pCO2, while other parameters (e.g. tissue biomass, total proteins, total lipids, protein carbonyls, some fatty acids and pigments) differed between reefs or showed pCO2–reef interactions. Tissue biomass, total lipids, and cell-protective capacities were distinctly higher in Porites spp. than in A. millepora, indicating higher resistance to environmental stress in massive Porites. However, our data suggest that important biochemical measures remain relatively unaffected in these two coral species in response to elevated pCO2 up to 800 µatm, with most responses being smaller than differences between species and locations, and also when compared with responses to other environmental stressors such as ocean warming.
