Cerebrospinal fluid protein estimation is a routine diagnostic tool for various diseases. The proposed modified bromocresol green (BCG) method is applicable to automated as well as manual measurements. Protein concentrations and absorbance at 600 nm are linearly related throughout a wide range of concentrations from 10 mg % to 2000 mg %. Ninety C.S.F. samples were analyzed and results obtained by both the modified BCG method and routine pyrogallol red method were compared. An excellent co-relation was observed (n=90, g=0.996, P<0.001).

In the present study the property of lecUn agglutination in blood on normal and different canGer patients has been observed. The purified SynadenlumgranUimot I~'tin was non blood group specific and its utility as s diagnostic tool in mlignancy was studied. Hemagglutinstion (units/ml) of red blood ceils of different types of cancer was compared with the normal control's red blood cells. Out of 113 totil cancer patients, only a group of 29 breast cancer patients showed significant increase in ;;t,-e value (P<0.06) compared to normal control.
