上呼吸道病毒感染患者血清细胞毒因子活性的研究

STUDY ON SERAL CYTOTOXIC FACTOR ACTIVITIES OF PATIENTS WITH VIRAL INFECTION OF THE UPPER RESPIRATORY TRACT

应用结晶紫染色法测得４３例上呼吸道病毒感染患者血清细胞毒活性（血清经５６℃、３０ｍｉｎ灭活）。结果表明；病人血清中的细胞毒活性明显升高，９３％的病人细胞毒活性达５０％以上。

It was examined seral cytotoxic activities of 43 patients with virus infection of the upper respiratory tract by the method of crystal violet stain (the serum was inactived at 56℃ for 30 min).The results showed that the beral cytotoxic activities were markedly increased,and the activities of 93% cases were over 50%
