Fig. 1From: Effect of a bradykinin potentiating factor separated from honey bee venom on thyroid gland and testis in hypothyroid white ratsPhotomicrographs of histological sections through the thyroid gland show cuboidal epithelium (Ep), homogenous eosinophilic colloid (Col), connective tissue septa (CT) between follicles in control (a). Negative homogenous eosinophilic colloid (arrows) in carbimazole- treated animals (b). Large quantity of homogenous- colloid (Col) with squamous epitheloidal cells (SE) in bradykinin potentiating factor and levothyroxine- treated animals were noted (c, d). Tissue recovery with homogenous colloid (Col) of the follicles in combined treatment with either bradykinin potentiating factor or levothyroxine was noticed in e, f.
