本文对241例(男127,女114例)1—7日龄的早期新生儿血清LD—L及其同功酶做了系统的研究,结果提示:①LD—L参考值为207.3±69.0,LD_134.4±12.8,LD_2 64.2±21.5,LD_3 64.6±25.5,LD_4 29.8±12.4,LD_5 14.2±8.0。②男女LD—L结果参考值分别为男215.7±75.1,女197.9±60.4,有显著性差异P<0.05。③各日龄组 LD—L结果变化随出生后日龄的增加,1日龄为 266.0±85.0至 7日龄170.3±47.1呈负相关性P<0.05。④LD—L及其同功酶与对照组成年人比较,LD—L为67.8±6.9,而新生儿为207.3±69.0明显的高于成人2倍多,其结果与过去文献报道一致,研究结论指出,早期新生儿由于生理上特点LD—L同功酶均较高,而且还存在性别差异。
In this paper, the serum LD-L and its isoenzymes in 241 cases (male 127, female 114) of early neonates aged 1-7 days were systematically studied. The results showed that: ①LD-L reference value was 207.3 ± 69.0, LD_134 .4 ± 12.8, LD_2 64.2 ± 21.5, LD_3 64.6 ± 25.5, LD_4 29.8 ± 12.4, LD_5 14.2 ± 8.0. ② The LD-L results of men and women were 215.7 ± 75.1 and 197.9 ± 60.4 respectively, with significant difference P <0.05. (3) The LD-L results of all age groups showed a negative correlation with the age at birth of 266.0 ± 85.0 days to 170.3 ± 47.1 days (P <0.05). ④LLD-L and its isoenzyme compared with the control group, the LD-L was 67.8 ± 6.9, while the newborn was 207.3 ± 69.0 significantly higher than the adult more than twice, the results consistent with the literature reported in the past, the study concluded that Early neonates due to physiological characteristics of LD-L isoenzyme are higher, but also there are gender differences.
