ABSTRACT
In order to improve the technique for histochemical demonstration of the different lymphocyte patterns by alpha-naphthyl acetate esterase (ANAE) activity from a single microscopic slide, 10 kinds of comparative experiments were performed. The results showed as follows. The peripheral blood mononuclear cells first fixed in 0.4% glutaldehyde and postfixed in 15% formol calcium gave the best effect on preserving the enzyme activity and on connterstaning of the leucocyte nuclei. During formol calcium fixation, the erythrocytes were dissolved from the diluted blood film with PBS more easily than from the blood smear without any dilution. The lymphocytes were distributed more uniformly and densely in the former specimen than in the latter. When incubated with 0.5 mg alpha-naphthyl acetate/ml medium in hexoazotized pararosaniline for 1(1/2)~2 hrs at 37℃, the distinct ANAE patterns of circulating lymphocytes were more readily identified.In 28 healthy adults the differential counts of the lymphocyte ANAE patterns from the diluted blood specimen was similar to those found from the specimen of isolated lymphocytes. The focal pattern was about 56%, the diffuse pattern about 25% and the negative pattern about 19%; while the isolated lymphocyte specimen was compared with the diluted blood film from the same individuals, the focal pattern was decreased insignificantly, the diffuse pattern increased and the negative pattern decreased significantly.
