ABO Blood-Group System

Publication Title: 
Experimental Gerontology

The aim of the present study was to investigate the association between blood groups and life expectancy. We compared frequencies of ABO blood group in 269 centenarians (persons over 100 years) living in Tokyo and those in regionally matched controls (n=7153). Frequencies of blood types A, O, B, and AB in centenarians were 34.2, 28.3, 29.4, and 8.2%, respectively, while those in controls were 38.6, 30.1, 21.9, and 9.4%, respectively. Blood type B was observed more frequently in centenarians than in controls (chi(2)=8.41, P=0.04).

The organ donor shortage has been the most important hindrance in getting listed patients transplanted. Living kidney donors who are incompatible with their intended recipients are an untapped resource for expanding the donor pool through participation in transplant exchanges. Chain transplantation takes this concept further, with the potential to benefit even more recipients.

OBJECTIVE: To evaluate the effect of traditional Chinese herbal medicine on the prevention of hemolytic disease caused by maternal-fetal blood group incompatibility. METHODS: A total of 126 Chinese patients with maternal-fetal blood group incompatibility were studied, including 105 cases of ABO type and 21 cases of Rh type incompatibility. The traditional Chinese herbal medicine was used for preventative treatment in 79 cases, and 47 cases served as controls.

Organisms release their antigens into the environment. Some antigens are volatile and may pass into the blood of other organisms during respiration. Fetal antigens enter the mother's bloodstream through the placenta. Foreign antigens in the blood can cause various chemical changes and may initiate an immune reaction.
