Food restriction promotes damage reduction in rat models of type 2 diabetes mellitus.

There are several animal models of type 2 diabetes mellitus induction but the comparison between models is scarce. Food restriction generates benefits, such as reducing oxidative stress, but there are few studies on its effects on diabetes. The objective of this study is to evaluate the differences in physiological and biochemical parameters between diabetes models and their responses to food restriction.

Insulin complexed with cyclodextrins stimulates epithelialization and neovascularization of skin wound healing in rats.

Introduction: Skin lesions are a significant public health problem, above all that wounds fail to heal properly and become chronic. Due to its reepithelization action, insulin has the potential to heal skin lesions, by stimulating the proliferation and migration of keratinocytes, angiogenic stimulus, and increasing collagen deposition. In the present study insulin was complexed with 2-hydroxypropyl-β-cyclodextrin (HPβCD) and its wound healing effect and inclusion complex (HPβCD-I) were evaluated in excisional wounds in the skin of rats.
