The Arnold-Chiari malformation (ACM) is an anomaly of the hindbrain consisting of two components: a variable displacement of a tongue of tissue derived from the inferior cerebellar vermis in the upper cervical canal and a similar caudal dislocation of the medulla and fourth ventricle. Hydrocephalus and meningomyelocele are another abnormalities that associated frequently. We present a case of Arnold-Chiari malformation with hydrocephalus and meningomyeolcele and a brief review of the literatures was added.

Malignant Mixed Mullerian tumors(MMMTs) are unusual neoplasms occumng mostly in the uterus and, ralely, they arise in the ovary. The clinical features of malignant mixed mullerian tumor of the ovary are similiar to other ovarian malignancies. The clinical course is rapidly progressive and fatal. The optimal treatment modalities has remained elusive. The most reliable prognostic criterion is the initial tumor stage and the overall survival was poor. We experienced two cases of malignant mixed miillerian tumor of the ovary, so we report these cases with a brief review of the concerned literatures.

The triad of bilateral optic atrophy, hearing deficit, peripheral neuropathy is knoun to be a rare disorder. The authors experienced eight patients in three generations of the same family with this triad of deficits. The disorder developed since their childhood and the course was slowly progressive. Nerve conduction study suggested peripheral neuropathy and sural nerve biopsy was compatible with demyelinating neuropathy, as there were reduction of myelinated nerve fibers in number and focal onion-bulb formation. The mode of inheritance of the family seems to be autosomal dominant, with relatively high penetrance. In many respects, the disorder resembles the cases reported by Sylvester(1958) and Iwashita et al.(1970). But still we do not know the exact etiology of this disorder.

Chronic binge alcohol drinking is a major cause of liver disease including steatosis, chronic hepatitis, and liver cirrhosis. The purpose of this study is to examine the change of oxidative/nitrosative stress in the chronic-binge ethanol model. Using wildtype (WT) mice, we show that chronic binge alcohol drinking develops steatosis and apoptotic cells. Furthermore, the activities of anti-oxidant and mitochondrial enzymes including catalase (CAT), superoxide dismutase 1 (SOD1) and glutathione peroxidase (GPx) were decreased in chronic binge alcohol-treated mice. Protein nitration was also increased in a chronic-binge group compared to pair-fed control counterpart. These findings suggest that chronic binge alcohol drinking plays a critical role in hepatic injury through oxidative/nitrosative stress.

In the case of crush injury, the failure rate of replantation of free tissue transfer is high. Recently, the freezing of intact and repaired microarteries has been known to relieve spasm without inducing thrombosis in vivo. Therefore, the author thought that the vascular freezing of crushed vein showing only unrecognized endothelial damage after adequate debridement of a damaged vessel can also relieve spasm without inducing thrombosis and improve the patency rate of microvascular anastomosis. In this study, the process of vascular freezing was investigated in veins with acutely damaged endothelium using ethly chloride in a rat model. Two experiments were performed in 30 Sprague-Dawley rats, weighing about 250 gm. In the first experiment, a new crush model was established on the femoral vein of the rats. The degree of vessel injury was evaluated as crush energy. The proper crush energy was determined only by the endothelial damage without inducing thrombosis(0.037 J). In the second experiment, femoral veins were crushed with the energy of 0.037 J on the left side and then frozen after inflicted crush injury with the same energy on the right side. The gross and pathologic findings and patency rates were observed at postoperative day 2, 10 and 30. Patency in both the crushed and crush-freezing group was 100%. Pathlolgic findings in the crush-freezing group were more severe loss of the intima and most parts of the media, as well as cellular depopulation of the media when compared to the crushed group. Microthrombi adherent to the wall were demonstrated in several crush-freezing specimens, but the crush-freezing group showed relief of crush-induced vasopasm and endothelial regeneration. In conclusion, the freezing of microveins with acute endothelial damage relieves spasm without inducing thrombosis. Therefore, this study presents the posslbility of clinical application of vascular freezing in a case of crush injury requiring microvascualr anastomosis.
