Zinc is a strong stimulant of metallothionein synthesis in the ischaemic testis tissue

Abstract

This study was performed to determine the effect of zinc supplementation effects on metallothionein levels in testis ischaemia-reperfusion of rats. The experimental groups were designed as Control, Sham, Ischaemia-Reperfusion (I/R) and I/R + Zinc supplemented. Zinc supplemented as 5 mg/kg day for 3 weeks. Testis tissues were analysed for metallothionein by immunohistochemical staining procedures. Group comparison showed that the zinc-supplemented ischaemia-reperfusion group had a significantly higher level of cells strongly stained with metallothionein than all other groups. A general evaluation of the results suggests that zinc supplementation is a strong stimulant of metallothionein synthesis in the ischaemic testis tissue.
