purpose: to evaluate the adverse effects of intravitreal injection of sterile chloramphenicol eye drops on corneal endothelial cells of donated corneas. methods: 100 donor corneas were enrolled in the study. one eye of each donor underwent intravitreal injection of sterile chloramphenicol eye drops following vitreous tap and the fellow eyes were served as controls. after corneo-scleral excision...

corneal transplantation is the most common and successful form of solid organ transplantation with a 2-year survival rate of over 90% in low risk cases. this high success rate may be due to the immune privileged status of the cornea, acaid (anterior chamber associated immune deviation) induction phenomena and secretion of inhibitory molecules by corneal cells such as il1-ra, il-1a and fas ligan...

Hydatid cyst of spleen is a rare condition compared to hydatid cyst of other organs. It ranges from 0.5-4.0 % of abdominal hydatid cyst. The most common sites for hydatid cyst are the liver (60-70%) and lung (10-40%). The first filter of hydatid cyst is liver followed by lung which acts as a second filter.
