In today's evolving global environment, reproductive dysfunctions brought on by various environmental toxins are of greatest concern. Radiation is a constant threat to living things, causing both genetic and cellular changes that result in mutations and cell death. It is thought that ultraviolet B (UVB) radiation we are exposed to daily has biological effects on rats and humans that are both short and long term. Due to the damaging effects of UVB radiation on the living system, this study explores the automatic mechanism by which a certain level of radiation induces oxidative stress, which is further controlled by the antioxidant activity of naringin (NG). In our study, male Swiss albino mice were exposed to UVB irradiation, which altered mice's body and testes weight, hormonal imbalance, biochemical parameters, and histo-morphometric parameter. In addition, we chose naringin's UVB irradiation deterrent effect. Twenty-four healthy adult male Swiss albino mice weighing 25-35 g were chosen at random. For 15 days of exposure, they were divided into four groups at random: group I-control, group II-UVB exposure (2 h per day), group III-UVB exposure with naringin (NG) (80 mg/kg, bw), and group IV-naringin (NG) (80 mg/kg, bw). Compared to the control group, UVB irradiation causes alterations in the animal body weight, testes weight, hormones, enzymatic and non-enzymatic assays, and histological parameters. It was seen that NG retrieved the alterations in parameters caused by UVB irradiation. The UVB radiation exposure on mice caused the testicular dysfunction drastically, while the naringin recapitulates testis functioning.
在当今不断变化的全球环境中,各种环境毒素引起的生殖功能障碍引起了最大的关注。辐射是生物的持续威胁,会导致遗传和细胞变化,从而导致突变和细胞死亡。人们认为,我们每天接触的紫外线 B(UVB)辐射对大鼠和人类既有短期影响,也有长期影响。由于 UVB 辐射对生命系统的破坏性影响,本研究探讨了一定水平的辐射如何自动引发氧化应激的机制,而柚皮苷(NG)的抗氧化活性进一步控制了这种机制。在我们的研究中,雄性瑞士白化病小鼠暴露于 UVB 辐射下,这改变了小鼠的身体和睾丸重量、激素失衡、生化参数和组织形态计量参数。此外,我们选择了柚皮苷对 UVB 辐射的抑制作用。随机选择 24 只体重为 25-35 g 的健康成年雄性瑞士白化病小鼠。暴露 15 天,随机分为四组:I 组-对照组,II 组-UVB 暴露(每天 2 小时),III 组-柚皮苷(NG)(80 mg/kg,bw)和 IV 组-柚皮苷(NG)(80 mg/kg,bw)。与对照组相比,UVB 辐射会改变动物体重、睾丸重量、激素、酶和非酶测定以及组织学参数。结果表明,NG 可恢复 UVB 辐射引起的参数变化。UVB 辐射暴露对小鼠的睾丸功能有明显影响,而柚皮苷则恢复了睾丸功能。
