Depending on the surface immunoglobulin of the lymphocyte membrane, lymphocyte has been classified either as a surface immunoglobulin bearing cell (SIBC) or a non-SIBC.<br>An ultrastructural approach of the freeze-etched lymphocyte membranes of normal subjects revealed the existence of micro-processes and small particles on its surface. The density of micro-processes on the lymphocyte membrane was distributed in the range from 0.3 to 6.8/μ2, and its histogram showed two peaks at 0-1 and 3-4/μ2.<br>The lymphocytes of normal subjects, in whom SIBC was in 18 percent, were freeze-etched, and 28 percent of the lymphocytes showed higher density of micro-processes more than 3/μ2. After the filtration of the lymphocytes through a tetron fiber column, the percentages of both SIBC and the lymphocytes showing the micro-processes more than 3/μ2 were decreased simultaneously.<br>In acute and chronic lymphocytic leukemias, the examination of lymphocyte subpopulations and the membrane architectures of the leukemic lymphocytes revealed the similar tendency of membrane property as observed in non-SIBC and SIBC of normal subjects.
