Abstract
The
present study was designed to investigate role of ethanolic extract of Tribulus
terrestris (EETT) against α-cypermethrin induced reproductive toxicity in male Wistar rats.
24 male Wistar rats weighing about 250-300g were divided in four groups.
Group-I was control. α-cypermethrin
(3.38 mg kg-1b.wt.) was
given to group-II for 28 days. In Group-III, α-cypermethrin and EETT (100 mg kg-1b.wt.) were administered in
combination for 28 days. Rats in group-IV were given EETT for 28 days. At the
end of the experiment, rats were sacrificed, testes and epididymis were
removed and sperm characteristics, sex hormones and various biochemical
parameters were studied. Decrease in weight of testes and epididymis,
testicular sperm head count, sperm motility, live sperm count, serum
testosterone (T), follicle stimulating hormone (FSH), leutinizing hormone
(LH), catalase (CAT), superoxide dismutase (SOD), glutathione S transferase
(GST), glutathione reductase (GR), glutathione peroxidase (GPx), total
protein content and increase in sperm abnormalities and lipid peroxidation
(LPO) level was observed in rats exposed to cypermethrin. In combination
group-III, EETT treatment ameliorated a-cypermethrin
induced damage. EETT treatment in group-IV increased testes and epididymis
weight, sperm head counts, sperm motility, live sperm counts, testosterone,
FSH, LH, GSH, CAT, SOD, GST, GR, GPx and total protein content. The study
suggested that Tribulus terrestris plant possess reproductive system
enhancement and antioxidant activity.?
