Combined effect of exposure to lead and chlordane on the testicular tissues of swiss mice.
Chlordane, is one of many environmental pollutants that reach human or animal body through food and water consumption, its presence may frequently be associated with other metals such as lead. In this work, the toxicity of chlordane and lead to reproductive tissues in Swiss mice was studied. Oral daily doses of 75 and 275 mg/kg b.w. were administered to male mice, for 35 days, animals were sacrificed at the 2nd, 3rd, 4th, and 5th week. The results show that chloradane had a damaging effect on testicular tissues, the effect was obvious through reduction in diameter of the seminiferous tubules, number of spermatogonia, and primary and secondary spermatocytes and spermatids. The effect was remarkably increased by the presence of lead, which needs more investigation in order to determine whether it's a synergistic or additive effect.
