为了探索冬泳对人体血管内血小板聚集及抗聚集系统的影响，我们对苏州市冬泳队中老年冬泳人员进行了血栓素Ｂ_２及６－酮－前列腺素Ｆ_（１α）血浆含量的放射免疫法测定。结果血栓素Ｂ_２为１０７．６±６３．３ｐｇ／ｍｌ，与正常健康人群对照，两者有显著性差异（ｐ＜０．０５）。６－酮－前列腺素Ｆ_（１α）为６３．４±２１．９ｐｇ／ｍｌ，与正常健康人群对照，两者差异不显著（ｐ＞０．０５）。提示冬泳运动有抗血管内血小板非正常聚集而释放血小板素的作用。同时亦提示冬泳人员的血管内皮细胞合成前列环素水平与对照组的低年龄组相近，两者皆对预防老年人罹患的动脉粥样硬化所致的心、脑、肾及其他脏器的血管内血栓形成有一定意义。
In order to explore the effect of winter swimming on human platelet aggregation and anti-aggregation system, we measured the plasma levels of thromboxane B 2 and 6-keto-prostaglandin F 1 (1α) in middle-aged and old winter swimmers in Suzhou winter swimming team by radioimmunoassay. Results Thromboxane B 2 was 107.6 ± 63.3pg / ml, which was significantly different from that of healthy controls (p <0.05). 6-keto-prostaglandin F_ (1α) was 63.4 ± 21.9pg / ml, which was not significantly different from that of normal healthy people (p> 0.05). Suggesting that winter swimming exercise anti-platelet aggregation and release of non-platelet function. At the same time, it also suggested that the level of prostacyclin synthesis in vascular endothelial cells of winter swimmers was similar to that of the control group, both of which were effective in preventing cardiovascular diseases such as heart, brain, kidney and other organs caused by atherosclerosis in the elderly Thrombosis within a certain significance.
