We recently reported the effects of repeated administration of the monoisoamyl ester of dimercaptosuccinic acid (MiADMSA) on a few selected biochemical variables indicative of haematopoietic, liver, kidney and brain toxicity, oxidative stress and essential metal status in male rats. The present investigation studies similar changes in female rats to fi nd out if the changes are independent of gender. The results suggest significant and pronounced toxic effects of MiADMSA on haem biosynthesis, liver and kidneys in female rats exposed to higher doses of orally (p.o.) or intraperitoneally (i.p.) administered MiADMSA, compared with the effects in male rats. No effects on brain tissues were seen. A pronounced depletion of copper was noted in the blood and liver of MiADMSA administered rats, irrespective of route of exposure. It can be concluded that the administration of MiADMSA in female rats is confounded with side-effects and may require caution during its use and further exploration.
我们最近报道了重复给予二巯基丁二酸单异戊酯(MiADMSA)对雄性大鼠一些选定的生化指标的影响,这些指标可指示造血、肝脏、肾脏和脑毒性、氧化应激以及必需金属状态。本研究调查了雌性大鼠的类似变化,以确定这些变化是否与性别无关。结果表明,与雄性大鼠相比,口服(p.o.)或腹腔注射(i.p.)高剂量MiADMSA的雌性大鼠,MiADMSA对其血红素生物合成、肝脏和肾脏具有显著且明显的毒性作用。未观察到对脑组织的影响。无论暴露途径如何,给予MiADMSA的大鼠血液和肝脏中铜均明显减少。可以得出结论,在雌性大鼠中给予MiADMSA会产生副作用,在使用和进一步研究时可能需要谨慎。
