Opsonisation and Nitrobluetetrazolium (NBT) reduction by granulocytes (gr) in exchangetransfusions (ET) of newborns

At the time of 23 ET, blood samples from 27 donors and 16 newborns were collected. Isolated gr. were test d for a) opsonisation index (OI) = mean number of Magocytised yeasts in 50 gr. incubated in serum, b) NBT test = % of stimulated gr. reducing NBT. ET with 25 donors having a normal opsonisation index (4.9±0.3) did not change the normal OI of 16… CONTINUE READING
