Abstract

Glucose are important amongst the several molecules available in the cells, Carbohydrates play an important role in the cellular process Under extreme stress conditions, carbohydrate metabolite such as glucose have been known to act as the energy supplier in metabolic pathways and biochemical reactions. In the present investigation fish treated with an equitoxic dose of 10 ppm of lead nitrate and lead acetate intoxicated fish After a period of 15 days of exposure a batch from lead nitrate exposed fish and a batch from lead acetate exposed fish were transferred to lead-freewater. Fishes were scarified on 1, 4, 8, 12 and 15 days for the analysis of recovery pattern in tissues viz. liver, muscle, kidney, gill and brain .It is found that lead toxicated fishes were recovered after 15 days depends upon physical condition of fish.

Abstract

Hussainsagar, the picturesque lake situated between the twin cities of Hyderabad and Secunderabad is an ecological and cultural land mark. It was excavated in 1562 mainly to store drinking water brought from the river Musi by Balakpur canal. However, with passage of time the lake lost its importance as a source of potable water. Nevertheless, it was extensively used for washing, bathing and recreation. Total despoilation of the lake is essentially post independence phenomenon and a direct result of unplanned industrialization and consequent urbanization. The past glory and beauty of lake could easily be comprehended from a poem written by the nightingale of India

Abstract

The effect of zinc sulphate on cardiac physiology of Bartelphusa guerini was investigated after acute exposure to zinc sulphate. Remarkable differences were found between control and treated crabs. The rate of heart beat was studied at regular interval of 24 h up to 240 h (10days). The investigation showed an initial decline in heart rate up to 48 h, which then gradually decreases up to 240 h in control group. The treated animals showed initial increase up to 72 h and later there is a gradual decline in the rate of heart beat up to 240 h. The decline in rate of heart beat may indicate that animals try to settle down to the toxic medium and initial increase in the heart beat rate may be due to accelerative metabolic activity of the animal.
