小檗胺在升高白细胞的同时对乳酸脱氢酶的影响

采用酶细胞化学及平板聚丙烯酰胺凝胶电泳法观察小檗胺(Ber)在升高白细胞的同时,是否对细胞内酶代谢及其同工酶有影响。结果表明:ip Ber的小鼠粒细胞内LDH酶反应明显增强,酶反应的强弱与用药时间长短成正比。LDH同工酶谱分析,所有标本均显示5条区带,LDH_2比例发生变化,对照组及Ber组中出现LDH’_5亚带。提示,Ber在升高白细胞的同时对细胞内酶的代谢有一定影响,同时伴有同工酶谱比例改变。

EFFECT OF BERBAMINE ON METABLIC ENZYME IN THE PROCESS OF INCREASING LEUKOCYTE

Berbamine ( Ber. ) is a bis-benzyl-isoquinoline alkaloid isolated from the traditional Chinese medical herb, Berberis poiretis, and has Vide pharmacological effects. Clinical studies have demonstrated that Ber. had an effect of ingreasing the number of leukocytes in various leukocytopenia. But, up till now it has not been reported that Ber. take effect on enzymic metablism of inner cell and isoenzyme in the process of increasing leukocyte. The experiment observed the mice dynamic change of LDH in leukocyte and LDH isoenzyme of serum by cytochemistry and plane polyacrylamide gel electrophoresis tech-nigue. The result indicates that LDH enzyme reaction of granulocyte have increased in Ber. group and intensity of enzyme reaction has a positive interralation with the time of administrations. All specimen show 5 zones after LDH isoenzyme pattern analyse. The proportion of LDH-5 was changed and LDH-5 sub-band was detected in control and combination group. The experiment indicated that Ber. can affeet enzymic metablism of inner cell in the process of increasing leukocyte. There was simultaneously with a change in ratio of LDH isoenzyme pattern.
