Delayed wound healing process is one of the most important concerns in diabetes. Healing of wounds has four phases, namely, hemostasis, inflammation, proliferation, and remodeling. For a successful repair, all four factors must occur properly. Hence, we aimed to evaluate the healing effects of Hypericum perforatum (HP) on full-thickness diabetic skin wounds by using stereological methods. Forty...

Wounds and wound healing have always been one of the most important subjects that experimental researches were dedicated to. Simvastatin has been used for long as a common lipid lowering agent which was reported to have some pleiotropic effects such as antioxidation, anti-inflammation and immunomodulation. In this study we aimed to determine the effect of simvastatin on wound healing process in...

The ciliary muscle in human eyes consists of bundles of muscle cells surrounded by flattened connective tissue cells. Each bundle generally contains unmyelinated nerve fibers accompanied by Schwann cells and a few connective tissue components. Some of the nerve fibers contain many vesicles characteristic of nerve endings. The nerve fibers are, in a few cases, in very close apposition to the mus...

The assembly, deposition and organization of collagen fibril bundles and their composite fibrils were studied during morphogenesis of the chick embryo tendon using electron microscopy, serial sections and computer-assisted three-dimensional reconstruction techniques. The 14-day chick embryo is a stage when tendon architecture is being established and rapid changes in the mechanical properties o...

ObjectiveTo evaluate the effects of autologous platelet-rich plasma (PRP) on wound healing in dogs. DesignExperimental in-vivo study. Animals5 mix-breed male adult dogs. ProceduresUnder general anesthesia, six 2 × 2-cm, full-thickness skin wounds were created on the back of dogs symmetrically. In each dog, three right side wounds were treated topically with 1.5 ml PRP jelly, whereas left side w...

acute yew (taxus baccata) intoxication was induced in 7 adult sheep by oral administration of the plant materials at the dose of 2.5g/kg body weight. blood samples for hematology and serum biochemistry were collected before and after the induced intoxication.electrocardiography was performed using a base-apex lead. intoxicated animals displayed lethargy, depression, bradycardia and varying inte...
