This study investigated testicular oxidative stress status and physiomorphological function in Wistar rats fed with yaji and cadmium chloride (CdCl2).
Sixty male albino Wistar rats (12 per group) were randomly assigned to five groups: group I (control), group II (300 mg/kg.bw of yaji), group III (500 mg/kg.bw of yaji), group IV (2.5 mg/kg.bw of CdCl2), and group V (2.5 mg/kg.bw of yaji+4 mg/kg.bw omega-3). Each group was evenly subdivided into two subgroups and treatment was administered for 14 days and 42 days, respectively. Semen quality (sperm count, progressive motility, normal morphology, and gonadosomatic index), hormones (testosterone, follicle-stimulating hormone, and luteinizing hormone), testicular oxidative stress markers (superoxide dismutase, catalase, glutathione peroxidase, and malonaldehyde) and testicular histomorphological features were examined.
Yaji caused significant (p< 0.05) dose- and duration-dependent reductions in semen quality, the gonadosomatic index, testosterone, follicle-stimulating hormone, and luteinizing hormone. Yaji also caused significant (p< 0.05) dose- and duration-dependent decreases in superoxide dismutase, catalase, and glutathione peroxidase activity, as well as increased testicular malonaldehyde levels. Yaji induced distortions in the testicular histological architecture. CdCl2 damaged testicular function by significantly (p< 0.05) reducing semen quality, reproductive hormone levels, and oxidative stress markers in albino Wistar rats. CdCl2 also altered the histology of the testis.
This study shows that yaji sauce has similar anti-fertility effects to those of CdCl2, as it adversely interferes with male reproduction by impairing oxidative stress markers and the function and morphological features of the testis.
本研究调查了喂食雅积和氯化镉(CdCl₂)的Wistar大鼠的睾丸氧化应激状态及生理形态功能。
将60只雄性白化Wistar大鼠(每组12只)随机分为五组:第一组(对照组)、第二组(300毫克/千克体重的雅积)、第三组(500毫克/千克体重的雅积)、第四组(2.5毫克/千克体重的CdCl₂)和第五组(2.5毫克/千克体重的雅积 + 4毫克/千克体重的ω-3)。每组再平均分为两个亚组,分别进行14天和42天的处理。检测精液质量(精子计数、前向运动率、正常形态和性腺指数)、激素(睾酮、促卵泡激素和促黄体生成素)、睾丸氧化应激标志物(超氧化物歧化酶、过氧化氢酶、谷胱甘肽过氧化物酶和丙二醛)以及睾丸组织形态学特征。
雅积导致精液质量、性腺指数、睾酮、促卵泡激素和促黄体生成素出现显著(p < 0.05)的剂量和时间依赖性降低。雅积还导致超氧化物歧化酶、过氧化氢酶和谷胱甘肽过氧化物酶活性出现显著(p < 0.05)的剂量和时间依赖性下降,同时睾丸丙二醛水平升高。雅积引起睾丸组织学结构扭曲。CdCl₂通过显著(p < 0.05)降低白化Wistar大鼠的精液质量、生殖激素水平和氧化应激标志物,损害睾丸功能。CdCl₂还改变了睾丸的组织学结构。
本研究表明,雅积酱与CdCl₂具有相似的抗生育作用,因为它通过损害氧化应激标志物以及睾丸的功能和形态特征,对雄性生殖产生不利影响。
