Cerebral cortical phospholipase A2 activity of senescence-accelerated mouse is increased in an age-dependent manner

An immunogenetic examination of 86 cases of stomach cancer established a correlation between predisposition and resistance, on the one hand, and the distribution of allele sets of HLA-genes (classes I and II), on the other. The relationship was found to vary according to sex and age. The most significant relationships with respect to predisposition were identified for HLA-B51 (RR = 19.82) alleles and allele combinations of HLA-DRI-DR7 (RR = 25.52) and HLA-A9-DRI (RR = 33.67). High relative risk of stomach cancer was attributed to the absence of relevant alleles in 91 patients included into the group of comparison. Also, combinations of allele sets were identified in healthy subjects which never occur in stomach cancer patients. The results provide a substantiation for developing an automated system of interpreting HLA-typing data which are instrumental in evaluating the patient's predisposition, resistance and prognosis.
