Root Tip Cells

The effects of different concentrations (10−5-10−2M) of lead nitrate on root growth and nucleoli in root tip cells of Brassica juncea L. were investigated. The results showed that lead nitrate has a stimulatory effect on root growth at lower concentrations, and an inhibitory effect at higher concentrations. Pb has toxic effects on chromosomal morphology, including c-mitosis and anaphase bridges, and on nucleoli, causing some particulate silver-stained material scattered in the nuclei and inducing irregularly shaped nucleoli. Once the nucleolus was affected, the root growth almost or completely stopped.

Histological Preparation

Matured and acclimatized specimens of Heteropneustes fossilis were exposed to 30 ppm cupric chloride. The fish were sacrificed on 15th day of ovaries and were excised out. Histological preparation by the method of OFG staining was studied. Histological observations were observed that there yolk investment appeared cracked and broken due to the treatment with various reagents during paraffin impregnation. The young ova proliferated from stroma appear quite small and without a distinction of core. Most of ova were showed quite thick encapsulation. Vitellogenesis was much pronounced and delayed in liberation of ova was expected.

Static Conditions

Stinging catfish Heteropneustes fossilis exposed to different concentrations of an organochlorine pesticide endosulfan under static conditions, revealed statistically significant increase in cholesterol contents of liver, brain and gill tissues even at the lowest concentration (0.0010 mg/l). Fish also elicited behavioral changes due to pesticide toxicity. Hypercholesterolemia appeared to be due to stress induced metabolic alterations caused by intoxication.
