Photomicrographs of histological changes of rat pancreata (Gomori stain).

<p>A) Non-diabetic: Normal histological structure of rat pancreata showing average sized islets (red arrow) and normal sized β cells. B) Diabetic control rat pancreata showing β cells slightly elongated with more destruction (++++). C) Concomitant administration of sitagliptin (5 mg/kg, p.o.) with cycloart-23-ene-3β, 25-diol (1 mg/kg, p.o.) treated rat pancreata showing slightly elongated of the β cells with less destruction (+).
