[Effect of age on hemostasis and plasma level of TXB2 and 6-keto-PGF1 alpha].

UNLABELLED

Hemostasis (HS) in 134 healthy subjects of over 20 years old was investigated. The cases with HS symptom were 45.5%, which increased with age. TXB2, 6-keto-PGF1 alpha and T/K ratio were measured by radioimmuno assay (RIA).

RESULTS

elevation of TXB2 was more significant in the middle age and old age than in the young group (P < 0.01). But the level of 6-keto-PGF1 alpha in various age group didn't changed significantly; while the ratio between TXB2 and 6-keto-PGF1 alpha was more significant in the aged than in the young person (P < 0.01). The results revealed that there was hypercoagulable tendency with the increase of age, and it was correlated with TXB2 and 6-keto-PGF1 alpha. It is significant in theory and practice to prevent and cure the cardiovascular and cerebrovascular disease as well as HS with the traditional Chinese medicine.
