The effect of alloxan diabetes and local irritating factors on gingival lymphocytes and plasma cells and serum IgG, IgM and IgA levels.

A histologic study was conducted in 5 diabetic and 5 non-diabetic albino rabbits to determine the effect of experimentally induced diabetes upon the number of gingival plasma cells and lymphocytes in the absence and presence of local factors, and IgG, IgM and IgA levels of the four groups were compared with each other. In conclusion, local factors were primarily responsible for the increase of the gingival plasma cells and lymphocytes. There was no statistically significant difference between the diabetic and non-diabetic group in the absence of local factors. Also, there was no marked difference between the serum IgG, IgA and IgM levels of all groups.
