摩杂一代水牛与广西沼泽型水牛肾上腺组织结构比较学研究

为探讨摩杂一代水牛与广西沼泽型水牛生产性能的差异,对其肾上腺组织结构进行比较研究。结果表明:水牛两侧肾上腺的形状大小不同,不同个体同侧的形状也不同,其被膜可清晰地分为外环层和内纵层,且广西沼泽型水牛被膜比摩杂一代水牛厚。广西沼泽型水牛比摩杂一代水牛的肾上腺球状带细胞长轴长2.00~4.00μm,网状带细胞长轴长4.00~5.00μm、短轴长2.00~3.00μm。由于广西沼泽型水牛肾上腺的被膜、球状带和束状带均比摩杂一代水牛厚,且网状带细胞显著大于摩杂一代水牛。因此可以推断,广西沼泽型水牛在调节心脏的活动和血管压力、抵御冷应激、对抗药物毒副作用等方面均优于摩杂一代水牛。

Microstructure Comparison Research of Adrenal Glands of Murrah Hybrid Buffalo and Guangxi Local Water Buffalo

In order to explore the differences of production performance between Murrah hybrid buffalo and Guangxi local water buffalo's, the organizational structures of adrenal gland between Murrah hybrid buffalo and Guangxi local water buffalo were compared . The results showed that the shape of both sides of the adrenal gland had different sizes, different individuals had the different shape of adrenal gland in the ipsilateral, the capsules of adrenal glands could be clearly divided into outer and inner layer line longitudinal layer, the envelope of Guangxi local buffalo was thicker than that of Murrah hybrid buffalo by the test of general anatomy. The spherical belt cell long axial of Guangxi local water buffalo was longer 2-4 μm than that of Murrah hybrid buffalo. The reticular zone cell's major axis of Guangxi local water buffalo was longer 4.00-5.00 μm than that of Murrah hybrid buffalo and the reticular zone cell's short axial was longer 2-3 μm than that of Murrah hybrid buffalo . Therfore,the conclusions were drawn that ,the abilities to regulating the cardiac activity and vascular pressure and resisting cold stress and side effect of the drug of Guangxi local water buffalo were superior to that of Murrah hybrid buffalo.
