(A) Hematoxylin and Eosin staining of granulomas from healthy individuals infected with M. tb. There was an aggregation of cells in both treated and untreated groups of granulomas formed by PBMCs of healthy individuals infected with Erdman strain of M. tb. But there was an apparent increase in the size of granulomas when treated with L-GSH; (B) Hematoxylin and Eosin staining of granulomas from T2DM individuals infected with M. tb. Granulomas were formed from PBMCs from T2DM patients. There was a great extent of cell aggregation when treated with L-GSH versus untreated. Microscopy work was done with a light microscope at 1000× magnification under oil immersion.
