Relationship between cardio-cerebral vascular diseases and prostatic special antigen content

  Objective   To determine prostatic special antigen(PSA)in sera for aged in eight elderly veteran sanitaria of military area and to discuss the effect on serum PSA for the factors of diet, cardio-cerebral vascular disease, et al.

  Methods   Studying object was aged males above 50 years old.The information about diet, cardio-cerebral vascular disease etc was collected by interview and questionnaire.Referring to Tandem R reagent box of international standard, ELISA was used to detect the PSA content in sera.

  Results   PSA content in sera in creased along with the age; PSA content of manual worker was(1.236±0.037)mg/ml; that of brainworker was(1.570±0.083)ng/ml; that of vegetarian was(1.128±0.027)ng/ml; that of carnivorous men was(2.523±0.053)ng/ml; comparison among groups was significant difference(P < 0.05).The PSA content of people without cardio-cerebral vascular disease was(1.261±01023)ng/ml; that of people with cardio-cerebral vascular disease was(2.246±0.026)ng/ml.THe difference between the two groups significant(P < 0105).

  Conclusion   PSA content in sera was positive correlation with age.Physical work and vegetarian diet helped to decrease PSA in sera and defend prostatic carcinoma.
