Figure 8

Kidney of a rat that was orally administered 1,000 mg/kg methanolic extract of Psychotria ankasensis (H&E x100 (a), x400 (c)). Renal tubules, glomeruli ((c) arrow), and interstitial tissues are well preserved, but blood vessels are moderately distended with blood (congested, (a) arrow) versus kidney of a control rat that was experimentally administered vehicleas control (H&E, x100 (b)), x400 (d). Tubule, glomeruli, and interstitial tissues have a normal structure. There is mild distension of blood vessels (congestion, see image (d) arrow).
