In the current study, we evaluated the endocrine disruption effect and oxidative stress implication of therapeutic dose of artemether-lumefantrine combination therapy on the ovary and uterus of rats. In this respect, female rats were divided into four groups: animals were per orally treated with tween 80 (control), artemether (4 mg kg body weight), lumefantrine (24 mg kg body weight) and artemether-lumefantrine (artemether, 4 mg kg body weight and lumefantrine, 24 mg kg body weight). We found that therapeutic doses of the drugs did not change the levels of ovarian hydrogen peroxide (HO) and malondialdehyde (MDA), but increased uterine levels of HO and MDA and reduced ovarian and uterine levels of reduced glutathione. In addition, whilst ovarian glutathione peroxidase (GPx) activity reduced in the lumefantrine monotherapy group, uterine GPx increased in the artemether monotherapy as well as the artemether-lumefantrine groups. Furthermore, the drugs reduced ovarian and uterine glutathione- S-transferase and uterine superoxide dismutase activities. The drugs reduced oestrogen level, whereas follicle-stimulating hormone was reduced by lumefantrine and artemether-lumefantrine therapies. Additionally, artemether and lumefantrine monotherapies significantly increased prolactin and progesterone levels compared with the control ( p < 0.05). The results suggest that in the absence of malarial parasite infection, the drugs induced oxidative stress in the ovary and uterus and disrupt hormonal balance in the rats.
在本研究中,我们评估了蒿甲醚-本芴醇联合疗法治疗剂量对大鼠卵巢和子宫的内分泌干扰作用及氧化应激影响。在这方面,将雌性大鼠分为四组:动物分别经口给予吐温80(对照组)、蒿甲醚(4毫克/千克体重)、本芴醇(24毫克/千克体重)以及蒿甲醚-本芴醇(蒿甲醚4毫克/千克体重和本芴醇24毫克/千克体重)。我们发现,这些药物的治疗剂量并未改变卵巢中过氧化氢(HO)和丙二醛(MDA)的水平,但增加了子宫中HO和MDA的水平,并降低了卵巢和子宫中还原型谷胱甘肽的水平。此外,虽然本芴醇单药治疗组卵巢谷胱甘肽过氧化物酶(GPx)活性降低,但蒿甲醚单药治疗组以及蒿甲醚-本芴醇组子宫中的GPx活性增加。此外,这些药物降低了卵巢和子宫中谷胱甘肽-S-转移酶以及子宫中超氧化物歧化酶的活性。这些药物降低了雌激素水平,而促卵泡激素在本芴醇和蒿甲醚-本芴醇治疗中降低。此外,与对照组相比,蒿甲醚和本芴醇单药治疗显著提高了催乳素和孕酮水平(p<0.05)。结果表明,在无疟原虫感染的情况下,这些药物在大鼠卵巢和子宫中诱导了氧化应激并扰乱了激素平衡。
