title: Effect of Vibrio cholerae-L-asparaginase on surface structure of splenic lymphocytes.
abstract: The surface ultrastructure of splenic lymphocytes and rosetting properties of lymphocytes of Swiss mice were studied under scanning electron microscope following transplantation of Dalton's lymphoma and ascites fibrosarcoma tumour cells and administration of Vibrio cholerae-L-asparaginase. The results were compared to those obtained with the standard Escherichia coli-L-asparaginase. The surface structure of the lymphocytes (T cells) following L-asparaginase administration was not so different from that of normal lymphocytes. V. cholerae-L-asparaginase did not cause higher number of rosette formation in T cells as compared to the normal group. The study thus revealed that V. cholerae-L-asparaginase did not have a significant stimulatory or non-immunosuppressive effect on the lymphocyte functions.
