An experimental of Vibrio vulnificus infection has been performed with the intravenous, subcutaneous and oral inoculation of Vibrio vulnificus into ICR mice. The results are as follows: 1) The LD50 of the intravenous, subcutaneous and oral inoculation of Vibrio vulnificus were 1.6x10(7) cells/ml, 4.0x10(7) cells/ml, and 2.5x10(9) cells/ml, respectively. 2) In the experimental group without treatment with CC14, the survival rates for intravenous inoculation were 100% (1/2 LD50), 39.1% (LD50), and 8.3% (2 LD50). The survival rates for subcutaneous inoculation groups were 100% (1/2 LD50), 46.9% (LD50), and 18.8% (2 LD50). And the survival rates for oral inoculation groups were 100% (1/2 LD50), 53.1% (LD50), and 43.8% (2 LD50). 3) In those treated with CC14 0.05 ml, the survival rates for intravenous inoculation groups were 43.8% (1/2 LD50), 29.1% (LD50), 0% (2 LD50). The survival rates for subcutaneous inoculation groups were 59.4% (1/2 LD50), 40.6% (LD50), and 9.4% (2 LD50). The survival rates for oral inoculation groups were 68.8% (1/2 LD50), 46.9% (LD50), and 18.8% (2 LD50). In those treated with CC14 0.1 ml, the survival rates for intravenous inoculation groups were 25.0% (1/2 LD50), 10.4% (LD50), and 0% (2 LD50). The survival rates for subcutaneous inoculation groups were 43.8% (1/2 LD50), 21.9% (LD50), 0% (2 LD50). The survival rates for oral inoculation groups were 50.0% (1/2 LD50), 37.5% (LD50), and 0% (2 LD50). 4) Liver, lungs, meninges and brain, kidneys, heart, gastrointestinal tract and spleen showed septic inflammatory findings. Their degree of inflammation were different according to the severity of hepatic damage and the inoculum size.

A prospective study of vitamin B6, B12, folate, and homocysteine levels was carried out in 7 kidney transplant(KT) recipients. The first sample for the basal level was drawn on the morning of the KT day before the start of cyclosporine injection. Thereafter, serial blood samples were taken every day until the serum creatinine level decreased below 1.5 mg/dl and then every 2 or 3days until discharge. The serum creatinine level decreased to below 1.5 mg/dl within 3days except for cases 4 and 6. The homocysteine levels decreased markedly in synchronisation with serum creatinine levels increased during the first 7days and then declined together with serum creatinine levels but went up again after a few days. The levels of B6, and vitamin B12 do not continue to decrease after the levels of serum creatinine have decreased to 1.5mg/dl, while homocysteine levels go up progressively. In conclusion, contrary to our expectation, the level of homocysteine rebounds a few days after KT following a transient decline. A deficiency of folic acid, vitamin B6 and vitamin B12 does not seem to cause hyperhomocysteinemia in KT recipients. It is necessary to pay attention to hyperhomocysteinemia in KT recipients, especially when the recipients have an atherosclerosis-related complication.

OBJECTIVE: The aims of this study were to analyze the natural history of patients with pseudomyxoma peritonei originated from mucinous ovarian tumor, evaluate clinical and pathologic variables, and review our experience with available therapeutic modalities. METHODS: Six patients were treated for pseudomyxoma peritonei originating from mucinous ovarian tumor at Severance Hospital between 1990 and 1998. The data were collected retrospectively and all charts were reviewed RESULTS: The mean age at diagnosis was 51 years, and most common symptoms were abdominal distension. Pseudomyxoma peritonei was found in association with five mucinous ovarian tumors of borderline malignancy, and one ovarian mucinous adenoma. All patients underwent surgical staging and cytoreduction, three patients received postoperative adjuvant chemotherapy and, of these, two developed recurrence. With respect to survival, all patients were alive, four were alive and free of disease, two were alive with disease at the end point of study. CONCLUSION: Pseudomyxoma peritonei is commonly associated with borderline mucinous ovarian tumors, and is a frequently relapsing and protracted disease. But aggressive and repeated debulking surgery is recommended for long survival.

Open fracture characteristically has higher chances of infection and sof tissue damage in comparison with closed fracture. In spite of the development of operation methods and antibiotics, complications such as infection, nonunion, delayed union, and joint stiffness are continuously confronted as problems in the field of orthopedics. Different methods of treatment have been advocated as regards the care of the open wound and the method of stabilization of the fracture fragments. Therefore a comparative analysis of the type of open fracture and the bone union time according to the initial treatment methods was made from 47 cases over the age of 20, who were followed up until bone union developed among the inpatients who were treated for open fracture of tibia in the period of 7 years from January, 1982 to December, 1988, and the results are as follows: 1. The highest incidence of fractures was encountered in 3rd decade(34%) and male to female ratio was 6:l. 2. The most common cause of fractures was traffic accident(76.6%). 3. The most common level of fracture was in mid one-third and the bone union time was longest in mid one-third. 4. The bone union time was longer, and the rate of complication was greater in order of type 1, 2 & 3 according to Gustilo's classification. 5. The good result was obtained in type 1 fractures, by using the closed reduction & cast immobilization and pin & plaster method; in type 2, the bone union time was shortest in the cases of pin & plater method; in type 3, the bone union time was shortest in the cases of closed reduction or open, reduction & external fixation. 6. Bone union was obtained in all cases of delayed union and nonunion and the bone union time was shortest in cases treated with plate & bone graft.

Unilateral nevoid telangiectasia(UNT) is a rare disorder and is characterized by superficial telangiectatic lesions distributed along the dermatomes unilaterally and usually on the upper part of the body. It has been said to be related to increased estrogen receptors in the involved skin. The lesions may be congenital or acquired.Acquired cases are typically associated with physiologic conditions such as pregnancy, puberty, hormonal therapy or cirrhosis, but the condition is also described in alcoholism without cirrhosis, carcinoma metastatic to the liver, and in hepatitis C. We present two cases of UNT in a 26-year-old man with heavy alcoholism and in a puberta1 16-year-old girl.
