A STUDY OF DISTRIBUTION OF A,B AND H SUBSTANCES IN HUMAN TISSUES / 中国法医学杂志

ABSTRACT

The distribution of ABH substances in human tissue cells was studied using the specific red cell adherence test(SRCA test).Tissues were taken from 11 cadavers of known ABO type and secrete status,fixed with 10% neutral formalin,Isolated abdominal skins kept in room temperature for 1～13 days were also observed for the purpose of studing the influence of the time elapsed after death on SRCA test results ABH substances were found in mucous membranes,mucous glands and prostate glands.ABH substances in those tissues were controlled by secrete status.ABH substances were also found in endothelia of blood vessels,stra- tified epithelia,acinar cells of pancreas and sweat glands.We firstly found that ABH substances were present in epithelia of pulmonary alveoli and epi- thelia of small bile duct in liver. Using SRCA test,the ABO blood type were correctly demonstrated in 11 isolated abdominal skins kept in room temperature for 1～13 days.
