The blood group and haemoglobin types of the Santals.

A total of 488 blood samples from tribal as well as non-tribal donors of Bihar and West Bengal were analysed for presence of abnormal haemoglobin variants. Out of 488 samples ABO and Rh blood groups were studied in 468 samples. Predominance of group B was noted in both the tribal and non-tribal groups and absence of Rh(d) was noted in non-tribal population with the exception of the tribals where 4.42% Rh(d) gene was found. Incidence of haemoglobin E gene was very low in most cases but relatively higher in non-tribal populations, while the range of raised haemoglobin A2 varied from 5.84% to 8.80%.

Total protein patterns in human amniotic fluid.

Total protein patterns of amniotic fluid samples of different age groups, following polyacrylamide disc gel electrophoresis, showed a wide range of variation in early pregnancy, but no two cases had identical banding, indenticating their genetic variability. An assessment has been made here of the total protein, albumin and transferrin patterns from normal fluids of different age groups by gel electrophoresis, in order to observe the genetic variations and relationship with foetal age, if any.
