RETRACTED: Histopathological Study of Cyclosporine Pulmonary Toxicity in Rats

Figure 4

(a) A photomicrograph of transverse section in the control rat lung shows positive PAS staining with normal architecture of alveoli (A) with thin interalveolar septa (s) and normal interstitial tissues (I) (PAS ×400). (b) A photomicrograph of transverse section in the second group rat lung shows moderate positive PAS staining with nearly normal architecture of alveoli (A), thick interalveolar septa (s), and interstitial tissues (I) (PAS ×400). (c) A photomicrograph of transverse section of third group rat lung shows negative PAS staining, accumulation of inflammatory cells near the blood vessels with abnormal architecture of alveoli (A), and destruction of the interalveolar septa (s) and interstitial tissues (I) (PAS ×400).
