Figure 2: Histopathology of lung (H and E stain, ×40). (a) Normal control group— normal alveolar morphology; (b) disease control group— severe (score 6) epithelioid cells (E), lymphocyte (L), alveolar wall infi ltration (A), caseation necrosis (CN), and giant cells (G); (c– e) isoniazid, rifampicin, and CSHMC (20 mg/kg) treated group— minimal (score 0.5– 1) epithelioid cells and alveolar wall infi ltration with no caseation necrosis and giant cell; (f) CSHMC (5 mg/kg) treated group— mild (score 1.5) epithelioid cells and alveolar wall infi ltration with no caseation necrosis and giant cell
