Correlation between Metroptosis Pathogenesis of Buffalo and Contents of Serum Calcium,Phosphorus and Antioxidation Levels

[Objective] The paper was to study the metroptosis pathogenesis of dairy buffalo.[Method]A total of 53 dairy buffaloes were selected to detect serum calcium,phosphorus,malondialdehyde（MDA） and total antioxidant capacity（TAC） levels.Dairy buffaloes were divided into metroptosis group（M） and healthy control group（UM） according to metroptosis situations of buffalo.The correlation between metroptosis of buffalo and calcium,phosphorus and oxidation/antioxidation levels in plasma was analyzed.[Result] The contents of serum calcium and phosphorus and oxidation/antioxidation level of dairy buffalo at the prenatal week and the calving day in M group were significantly lower than that in UM group.The TAC level of dairy buffalo in M group from the first three weeks to the calving day was significantly lower than that in UM group.The MDA level in M group was significantly higher than that in UM group.[Conclusion] The occurrence of postpartum metroptosis in buffalo was related to insufficient levels of calcium and phosphorus in prepartum buffalo,declined total antioxidation capacity and accumulation of peroxide products.

改良阴式子宫切除术282例临床分析

【目的】比较非脱垂子宫经阴道切除术与腹式子宫切除术的手术效果。【方法】分析 2 82例非脱垂子宫的改良阴式切除术和 2 5 0例同期指征相近的腹式子宫切除术的手术时间、术中出血量、术后体温、肛门排气时间、术后病人下床活动时间、住院天数及术后 3个月随访情况进行比较。【结果】改良阴式子宫切除术组在手术时间、术中出血量、术后体温、术后排气时间、下床活动时间及住院天数均少于腹式子宫切除术组 (P <0 .0 1) ,术后 3个月随访阴道残端愈合、下腹部疼痛等 (P >0 .0 5 )。【结论】改良阴式子宫切除术 。
