Abstract-Chronically diabetic rats prepared by a single i.v. Injection of strepto zotocin were used to study whether royal jelly (RJ) possesses a hypoglycemic reaction and whether it can augment wound healing. Oral RJ administration of 10, 100 and 1000 mg/kg/day did not show any insulin-like activity (the hypo glycemic reaction). RJ, however, showed some anti-inflammatory activity by decreasing exudation and collagen formation in granulation tissue formation in the cotton pellet method. RJ also shortened the healing period of desquamated skin lesions. Thus, RJ possesses an anti-inflammatory action and is able to augment wound healing, but does not have an insulin-like action in streptozotocin-diabetic rats.
Ampicillin (ABPC) concentrations in human serum, gingiva, the mandibular bone, and dental follicle after a single oral administration of ampicillin (500 mg) were assayed by the agar diffusion (paper disc) method. The peak times of all specimens were identical, being 120 min after administration. The peak concentrations of the respective specimens were 2.01 micrograms/ml, 1.03, 0.34, and 0.72 micrograms/g, respectively. The concentration ratios of gingiva, the mandibular bone, and dental follicle to their corresponding serum at the peak time were 0.51, 0.16, and 0.35, respectively.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
