Until now it had been assumed that mammalian skin contains only one provitamin D, 7-dehydrocholesterol, that is eventually converted to vitamin D3 after the skin is exposed to sunlight. Examination by reverse phase high performance liquid chromatography of lipid extracts from young rat skin, however, led to the observation that 7-dehydrocholesterol is not the only provitamin D in rat skin. Anot...

Purpose:Human amniotic fluid contains several growth factors and hyaluronic acid. It has positive effect in healing the tendon, nerve bone injuries. Human membrane effects on is also used for skin burns complex wounds. We hypothesized that human have stimulating fracture healing. The aim of this study to investigate rat tibial model.

Adult CBA mice may be made tolerant of August rat tail skin grafts by short intensive treatments with antilymphocyte serum followed by massive ( approximately 100 x 10(6) cells) injections of August rat lymphoid cells. Prolonged tolerance can be achieved only in thymectomized mice, and is accompanied by lymphoid cell chimerism and the manufacture of rat protein. The rat lymphoid cell donors mus...

Objective(s)Tissue engineering is an attractive science because it promises new therapeutic strategies for repairing organs that have lost functions due to damage. The purpose of this study was to evaluate induction effect of human gingival scaffold in tissue engineering for skin regeneration.Materials and MethodsTissue samples were obtained from crown-lengthening procedures and wisdom teeth re...

Purine-catabolizing enzymes are widely distributed among various tissues of mammalian organisms (l-5). There are indications that, at least in the case of the white rat, some of these enzymes are also present in skin. Barry et al. (6) and, more recently, Westerfeld and Richert (5) have found xanthine oxidase in rat skin. We have confirmed this finding (7) and have further shown that adenosine d...

ABSTRACT The present study was undertaken to determine the diffusion rate of a drug from a semisolid dosage form using different membranes and to explore a membrane and to find out the comparative membrane identical to human skin with respect to diffusion rate of the drug from the selected dosage form. In the present study, Franz cell was used to carry out the diffusion study through fuzzy rat ...
