Lead induced testicular changes in protein malnourished rats

The effect of concurrent low protein (8% casein) diet and lead (Pb) exposure (1 mg/ml lead acetate in drinking water) on testes of weaned rats up to 90 days of age was investigated Histopathological examination of testes of lead treated rats maintained on low protein diet revealed marked pathological changes associated with greatly reduced succinic dehydrogenase, glucose-6-phosphate dehydrogenase and adenosine triphosphatase activity as revealed histochemically compared to lead treated rats fed normal protein diet. It was concluded that higher accumulation of lead may be responsible for altering the enzyme levels and inducing the testicular degeneration to a greater extent in low protein fed rats compared to their counterpart controls.
