Effects of implantation of fresh and stored vitreous were studied on albino rabbits. Auto-and bomo- implantations of fresh vitreous were performed in sixty eyes, and course was followed up to one month after implantation operation. Of these, thirteen eyes were discarded because of bleeding into vitreous cavities and contamination of vitreous by blood. In remaining forty-seven eyes, vitreous became clear after ten days. Intraocular pressure which had been low daring the first few days, normalized within this period of time. No complication was observed. Implantation of homologous vitreous which had been stored in frozen state for one to three months, resulted in clear vitreous in eight out of ten eyes operated. Bleeding and blood contamination occurred in two eyes. From the results, it can be concluded that vitreous implantation is relatively safe and effective procedure.

Three dead dogs were brought to the College of Veterinary Medicine, Kyungpook National University for study. Clinically, all the dogs showed emaciation, anorexia, depression, hemorrhagic vomiting and diarrhea for 7~10 days before death. All the clinical signs were first noted for about one month after feeding the dogs with commercial diets. At necropsy, all 3 dogs had severe renal damage with the same green-yellowish colored nephroliths in the renal pelvis. They also showed systemic hemorrhage and calcification of several organs, which might have been induced by uremia. Microscopically, necrosis, calcification and calculi were detected in the renal tubules, and especially in the proximal convoluted tubules and collecting ducts of the kidney. These findings were supportive of a mycotoxic effect, and especially on their kidneys. However, the precise cause of the toxic effect in these cases of canine renal failure could not be determined.
