a lot of researches have investigated the effects of topical cyclosporine a on the eye surface layers' diseases. by now the main limitation in cyclosporine application is the low permeation of the drug into the posterior segments of the eye. the aim of present study was to formulate high permeable dosage form can be beneficial in the topical treatment of the uveitis. to reach higher corneal dru...

Background and Objective: Artimisinin (an anti-malaria drug) is extracted from Artemisia annua and its water soluble derivative is dihydroartimisinin. Previous in vivo and in vitro studies showed that it has an inhibitory effect on T cells. It is also useful for immunosuppression of immune system. Materials and Methods: The stable state kinetic for comparison of inhibitory effect of artimisinin...

Background: Cyclosporine is the main immunosuppressive agent used in organ transplantation which leads to considerable improvement in graft survival.  The large inter- and intra- patient variability in cyclosporine pharmacokinetics coupled with the agent’s narrow therapeutic index and adverse effects necessitate therapeutic monitoring of cyclosporine blood levels. Objective: The aim of this stu...

cyclosporine a (csa), a cyclic polypeptide metabolite extracted from the fungus, is used clinically to combat organ graft rejection in transplant subjects. previous studies have shown that csa exposure enhances the production of reactive oxygen species (ros) and lipid peroxidation, which are directly involved in csa toxicity. to protect cells and organs against ros, the human body has evolved a...

Spermatogenesis process during which the male germ cells are produced at each stage of the disorder, it can lead to infertility. The aim of this study was to evaluate the effect of fennel and yarrow on spermatogenesis in adult micereceiving chemotherapy is cyclosporine. For this study, 32 male Wistar rats with an average weight of 20 ± 200 g were randomly divided into four groups (control, cycl...
