Fruit extract of (TT) bears aphrodisiac and antioxidative properties. Antimicrobial drug, metronidazole (MTZ) impairs the spermatogenic activity and fertility in males.
Validation of the use of fruit extract of TT as a supplement against MTZ-induced fertility impairment in males.
Adult Swiss strain male mice were administered with 500mg/kgBW/day of MTZ for 28 days. Low (100mg/kgBW/day) and high (200mg/kgBW/day) doses of TT were administered simultaneously with MTZ (500mg/kgBW/day) for same duration. All males were cohabited with virgin proestrus females. Vaginal plug formation was observed to calculate the libido index. Cohabited females were sacrificed on fifteenth day of gestation to dissect out the ovaries and uteri. Fertility index, quantal pregnancy, pre-implantation and post-implantation losses were calculated.
MTZ-treated males showed unaltered mating ability, however, the females impregnated by such males exhibited marked alterations in the fertility index, quantal pregnancy and pre- and post-implantation losses. Supplementation with low dose of TT failed to restore such reproductive toxicities exhibited by administration of MTZ. However, the altered reproductive toxicities were reinstated to control values following supplementation with high dose of TT.
The fruit extract of TT may emerge as an effective herbal remedy, correcting the drug-induced fertility impairments in males.
[植物名称](TT)的果实提取物具有壮阳和抗氧化特性。抗菌药物甲硝唑(MTZ)会损害男性的生精活性和生育能力。
验证TT果实提取物作为补充剂对抗MTZ诱导的男性生育能力损害的用途。
给成年瑞士品系雄性小鼠每天腹腔注射500mg/kg体重的MTZ,持续28天。低剂量(100mg/kg体重/天)和高剂量(200mg/kg体重/天)的TT与MTZ(500mg/kg体重/天)同时给药相同时间。所有雄性小鼠与未交配过的处于发情前期的雌性小鼠合笼饲养。观察阴道栓形成情况以计算性欲指数。在妊娠第15天处死合笼饲养的雌性小鼠,取出卵巢和子宫。计算生育指数、定量妊娠、着床前和着床后损失。
经MTZ处理的雄性小鼠交配能力未改变,然而,被此类雄性小鼠使受孕的雌性小鼠在生育指数、定量妊娠以及着床前和着床后损失方面表现出明显变化。补充低剂量的TT未能恢复MTZ给药所表现出的此类生殖毒性。然而,补充高剂量的TT后,改变的生殖毒性恢复到了对照值。
TT的果实提取物可能成为一种有效的草药疗法,纠正药物诱导的男性生育能力损害。
