摘要:
为了探讨硒对新西兰兔毛囊发育的影响机制，本研究将60只初始体质量为 （690.0±7.0） g的新西兰兔分为C和SS 2组，每组30只（雌雄各半）。C组直接饲喂基础日粮，SS组日粮添加亚硒酸钠，经测定日粮硒含量分别为0.20 mg/kg和0.36 mg/kg，饲养30 d。结果表明，C组新西兰兔的毛囊群结构排列整齐，1个初级毛囊周围环绕数个次级毛囊，且毛囊横切面呈正常椭圆形。SS组新西兰兔的毛囊群结构呈无序排列，初级毛囊和部分次级毛囊的横切面不是正常的椭圆形。SS组次级毛囊数量比C组低36.64%（P<0.05）。在皮肤抗氧化性方面，与C组相比，SS组皮肤组织中谷胱甘肽过氧化物酶4(GPx4)活性、超氧化物歧化酶(SOD)活性、总抗氧化物(T-AOC)含量分别降低58.09%（P<0.01）、34.39%（P<0.05）和59.25%（P<0.01），丙二醛（MDA）含量升高242.66%（P<0.05）。与C组相比，SS组新西兰兔皮肤毛囊中GPx4蛋白、表皮生长因子受体（EGFR）蛋白表达量分别降低131.70%（P<0.01）和128.60%（P<0.01）。
Abstract:
To investigate the effect of selenium on hair follicle development and expression of GPx4 protein in rabbit hair, 60 New Zealand rabbits which initial weight was （690.0±7.0） g were divided into two groups(C and SS), 30 rabbits in each group (male and female). The C group was fed on basal diet, the determination of dietary selenium level was 0.20 mg/kg, SS group of dietary sodium selenite, the determination of dietary selenium level was 0.36 mg/kg. Feeding 30 d. Rabbit hair follicle group structure of C group arranged neatly, a primary hair follicle was surrounded by a number of secondary follicles, hair follicles and oval cross section was normal. New Zealand rabbit hair follicle group structure of SS group was disordered, transverse section of primary follicles and part of secondary follicles were not normal. The number of secondary follicles in SS group was decreased by 36.64% than that in C group （P<0.05）. The antioxidant properties of the skin, compared with the C group, the GPx4 activity of SS group in skin tissue significantly decreased by 58.09% （P<0.01）, SOD activity significantly decreased by 34.39% （P<0.05）, T-AOC activity significantly decreased by 59.25% （P<0.01）, the content of MDA significantly increased by 242.66% （P<0.05）.The expression of GPx4 and EGFR proteins of New Zealand rabbit skin hair follicles in SS group were significantly decreased by the 131.70%（P<0.01）and 128.60% （P<0.01） than that in C group.
