한우(韓牛)의 선천성용혈감수성검사(先天性溶血感受性檢査)에 대한 methylene blue 청색소실시험법(靑色消失試驗法)의 적용(適用)

Application of methylene blue color test for the detection of inherited susceptibility to hemolysis of Korean native cattle

Blood samples were obtained from Korean native cattle and dairy cattle of Holstein species in the slaughter house and methylene blue color tests were performed for the detection of the inherited susceptibitity to hemolysis. Glucose-6-phosphate dehydrogenase activities expressed as the optical density obtained by methylene blue color test were the highest as 0.54 in male Korean cattle, 0.62 in female Korean cattle and 0.72 in dairy cattle of Holstein species. Percent hemolysis, packed cell volume and plasma protein contents were measured and compaired with relation to the results of methylene blue color test and no correlation were observed in each.
