摘　　要：测定了西藏嘉黎牦牛和南京荷斯坦牛血液红细胞中乳酸脱氢酶 (LDH)、碱性磷酸酶 (AKP)、过氧化氢酶 (CAT)、超氧化物歧化酶 (SOD)等 4项酶的活性 ,结果分别为LDH 2 5 5 2 3 1 6± 71 4 0 3和 2 1 2 74 96± 6638 1 6(nmol s) ,AKP 4 4 4 4± 1 2 81和 36 5 3± 1 1 31 (nmol s) ,CAT 1 0 2 73± 32 2 2和 63 0 8± 1 2 4 7(U gHb) ,SOD 1 3979 1 6± 2 873 84和 92 85 37± 2 880 60 (U gHb)。西藏嘉黎牦牛的CAT和SOD极显著高于荷斯坦牛 (P <0 0 1 ) ;而LDH和AKP显著高于荷斯坦牛 (P <0 0 5 )。The activity values of four enzymes in the red blood cells of Jiali yaks were studied and compared to those of Holstein cattle. The four enzymes were LDH, AKP, CAT, and SOD. The results show: LDH 25?523.16±7?140.30 vs 21?274.96±6?638.16 (nmol/s), AKP 44.44±12.81 vs 36.53±11.31 (nmol/s), CAT 102.73±32.22 vs 63.08±12.47 (U/gHb),SOD 13?979.16±2?873.84 vs 9?285.37±2?880.60 (U/g Hb). The enzyme activities of CAT and SOD in Jiali Yaks were significantly higher than those in Holsteins (P<0.01). There was a significant increase in LDH and AKP activities in Jiali Yaks compared to Holsteins (P<0.05).
