The acid phosphatase and protease, neutral protease, bactericidal and mitogenic activities were determined in the polymorphonuclear leukocyte (PMNL) lysosomes of 16 years old boys. The investigated group consisted of 20 intense sport training persons during the last six years, the control one of the same age boys without any sport training. The significant decrease of hydrolase activity has been observed in the lysosomes of the peripheral blood PMNL's of the sport training boys.
对16岁男孩多形核白细胞（PMNL）溶酶体中的酸性磷酸酶、蛋白酶、中性蛋白酶、杀菌和促有丝分裂活性进行了测定。研究组由过去六年中进行高强度运动训练的20人组成，对照组为同龄未进行任何运动训练的男孩。在进行运动训练的男孩外周血PMNL的溶酶体中，观察到水解酶活性显著降低。
