Cryopreservation is able to store the surplus pre-embryos for freezing and furthermore thawing and transfer in a subsequent cycle. Cryopreserving cells which are maintaining their viability are the very complex process. This study has been carried out in order to find the effects of cryopreservation steps, freezing media and embryonic stages on the rates of viability and development of cryopreserved mouse embryos. Female ICR mice (6~8 weeks old) were induced to superovulate by sequential intraperitoneal injection of 5 IU PMSG and 5 IU hGC 48h apart. Mouse embryos were collected according to its developmental stage after the injection of hCG. Embryos were cryopreserved not only by cryoprotectant step (1 step~ 4 step) but also in a variety of media (HTF, IVF medium, D-PBS) and cell stage. The results were as follows: There is no clear advantage in these freezing media of rapid method, but 4 cell and 8 cell of slow method (2, 3, 4 step) have advantage in D-PBS. The development of embryos according to cell stage become greater in 8 cell stage. In the treatment steps of cryopreservation, the development of embryo to blastocyst was similar among rapid method, but the development of 4 cell and 8 cell embryos to blastocyst according to slow method was better than rapid method.

A series of clinical studies on the psychiatric aspects of hemodialysis and kidney transplantation were done with Korean patients, kidney donors, their families and unit nurses. All subjects were interviewed and evaluated for their psychiatric reactions and symptoms and for the underlying causes. Depression was the most common reaction, although the clinical features were somewhat different between groups studied. In addition, a unique and episodic psychotic syndrome was found in four patients. Depression and psychotic episodes seemed to reflect the psychodynamic components such as instinctual frustration, physical, familial and financial loss, dependency on a machine, sensory deprivation and the so-called fear of death and fear of life. These seemed to follow the unique features of hemodialysis and transplantation. The main defense mechanism seemed to be denial. The possible role of psychiatrists was discussed for evaluation, treatment, and prevention of these reactions and for the support of the family and the treatment team.

Insulin deficiency due to destruction of pancreatic beta-cells is a typical characteristic of type 1 diabetes mellitus (DM). In 2000 Imagawa proposed a novel diagnostic model defining "fulminant type 1 DM" as developing rapidly without any evidence of autoimmunity, and ever since there have been many reports regarding the matter in Japan. In 2004, the first fulminant type 1 diabetes case was reported in Korea; however, there have been few reports since then. We present a case of a 60-year-old man who suffered from excessive thirst and polyuria after myalgia. Laboratory findings revealed a high blood glucose level and evidence of diabetic ketoacidosis, but the HbA1c level was within the normal range. The serum C-peptide level was very low and antibodies to glutamic acid decarboxylase were negative. These findings suggested fulminant type 1 diabetes. This patient has shown improvement in symptoms and examination results without complications after being treated with insulin therapy with hydration, throughout 6-months follow-up period.
