Figure 5

Representative micrographs of the lung tissue in Sprague–Dawley rats after six weeks of CSE C. citratus ethanolic extract administration (x100). The micrographs show normal lung architecture with alveolar spaces (A), bronchiole (BC), and blood vessels (BV) with no inflammation, fibrosis, or neoplastic change in all treatment groups. (a) Lung tissue of control rats treated with sterilized distilled, (b) lung tissue of rats treated with 200 mg/kg bw.t CSE C. citratus ethanolic extract, (c) lung tissue of rats treated with 600 mg/kg bw.t CSE C. citratus ethanolic extract, and (d) lung tissue of rats treated with 1200 mg/kg bw.t CSE C. citratus ethanolic extract.
