The selective effect of tunicamycin on the secretion of IgM and IgG produced by the same cells.

Cells of the hybridoma cell line X63/38 C-13 secreting both IgM and IgG have been used in studies on the importance of the carbohydrate moieties of the Ig molecules for their secretion. It has been found that the secretion of the IgM produced in the presence of the glycosylation inhibitor tunicamycin was strongly inhibited, while the secretion of the IgG produced by the same cells was only slightly affected.

Induction of secretion of IgM from cells of the B cell line 38c-13 by somatic cell hybridization.

Cells of the murine B cell line 38C-13 possess immunoglobulins of the IgM class on their surface but do not secrete them. Upon hybridization of 38C-13 cells with murine myeloma cells, hybridoma clones were obtained that secreted both pentameric IgM of 38C-13 origin and the myeloma protein. All hybridoma clones synthesized and secreted large amounts of homogeneous IgM with a half disappearance time of about 2 hr, typical of mature plasma cells. Concomitantly with the induction of IgM secretion, the hybridoma cells lost their surface IgM. The possibility of separate pathways for the synthesis of membrane and secreted IgM is discussed.

Clinical experience with technetium-99m stannous polyphosphate for myocardial imaging.

Myocardial imaging with technetium-99m stannous polyphosphate was performed on 46 patients. Eleven patients had no cardiac disease, 22 had acute myocardial infarction, and 13 had stable arteriosclerotic heart disease. Distinct patterns of myocardial activity were noted: (1) the patients with no obvious cardiac disease showed no cardiac activity; (2) stable arteriosclerotic heart disease showed faint, ill-defined cardiac activity, primarily in the anterior or inferior aspect of the left ventricle; (3) acute myocardial infarction showed intense, focal, well-defined activity, with a shape that characterized the location of the infarct.
