Between December 1994 and December 1996, 42 patients underwent arthroscopic meniscal repair in our institute. Among them, 31 patients with a follow up more than one year were reviewed. Mean age was 24.4 years(range, 18-52 years) and mean interval between onset of symptom and opera- tion was 12.3 months(range, 3 days-6 years). The associated injuries were tibial plateau fracture(6 cases), anterior cruciate ligament injury(4 cases) and posterior cruciate ligament injury(2 cases). The type of tear were longitudinal in 28 cases(90%) and combined in 3 cases(10%). Most of the meniscal tear were encountered in posterior hom(12 cases, 39%) and middle portion(11 cases, 35%). Out side to in technique was used in anterior horn tears and inside to out technique in middle or posterior hom tears. In tibial plateau fractures, arthroscopic assisted reduction was performed with autogenous bone graft. Ligament reconstructions were performed in the cases of associated cruciate ligament injury. According to Ikeuchis grading system, the result was satisfactory(excellent or good) in 23 cases(74%), fair in 6 cases(19%) and poor in 2 cases(6%). But in the cases of isolated meniscal injury, the result was satisfactory in 95%. The result of arthroscopic repair in the meniscal tears associated with other intra-articular injuries seems to be worse than that of the isolated injuries.

BACKGROUND: Exposure to ethanol abuse and severe oxidative stress are risk factors for hepatocarcinoma. The aim of this study was to evaluate the effects of S-adenosylmethionine (SAMe) and its combinations with taurine and/or betaine on the level of glutathione (GSH), a powerful antioxidant in the liver, in acute hepatotoxicity induced by ethanol. METHODS: To examine the effects of SAMe and its combinations with taurine and/or betaine on ethanol-induced hepatotoxicity, AML12 cells and C57BL/6 mice were pretreated with SAMe, taurine, and/or betaine, followed by ethanol challenge. Cell viability was detected with an MTT assay. GSH concentration and mRNA levels of GSH synthetic enzymes were measured using GSH reductase and quantitative real-time reverse transcriptase-PCR. Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities were measured with commercially available kits. RESULTS: Pretreatment of SAMe, with or without taurine and/or betaine, attenuated decreases in GSH levels and mRNA expression of the catalytic subunit of glutamate-cysteine ligase (GCL), the rate-limiting enzyme for GSH synthesis, in ethanol-treated cells and mice. mRNA levels of the modifier subunit of GCL and glutathione synthetase were increased in mice treated with SAMe combinations. SAMe, taurine, and/or betaine pretreatment restored serum ALT and AST levels to control levels in the ethanol-treated group. CONCLUSIONS: Combinations of SAMe with taurine and/or betaine have a hepatoprotective effect against ethanol-induced liver injury by maintaining GSH homeostasis.

BACKGROUND: Several mechanisms for the pathogenesis of many liver diseases are related with oxidative stress, endotoxins, and infections by many microorganisms. These can lead to chronic hepatitis, cirrhosis, and even liver cancer. The aim of this study was to evaluate the effects of S-adenosylmethionine (SAMe) and its combinations with taurine and/or betaine against hepatotoxicites induced by lipopolysaccharide (LPS) or polyinosinic-polycytidylic acid (polyI:C). METHODS: RAW 264.7 macrophage cells and seven-week-old male C57BL/6 mice were pretreated with SAMe (SAM or AdoMet), taurine, and/or betaine. In order to mimic hepatic injury like endotoxemia or viral infection, cells and mice were treated with LPS or polyI:C. Concentrations of glutathione (GSH), mRNA expressions of GSH synthesizing enzymes, and inflammatory markers were measured by biochemical assays and quantitative real-time PCR. RESULTS: In RAW 264.7 cells and mice, pretreatment of SAMe alone or SAMe with taurine and/or betaine attenuated the decrease in GSH levels and mRNA expressions of GSH synthesizing enzymes. In addition, pretreatment of SAMe with taurine and/or betaine prevented the excessive increase in inflammatory mediators produced by LPS or polyI:C treatment. CONCLUSIONS: Treatment with SAMe in combination with taurine and betaine, would have anti-oxidant functions in addition to anti-inflammatory action against bacterial and/or viral inflammation.

Eleven cases of juvenile diabetes mellitus who were admitted Seoul National University Hospital from Jan., 1969 to Aug., 1978 were aha1yzed. The mean age of onset was 7 and female to male ratio was 8 to 3 with female preponderance. Four had family history of diabetes, although none had diabetic sibling. Polyuria and polydipsia were noted in all cases as initial symptoms, and symptoms of weight loss (6 cases), disturbances in consciousness (5), generalized weakness (5), anorexia (4) and enuresis (3) were noted in the order of frequency. Leucocytosis was noted in 5 cases, but only 2 among the 4 who had infection revealed leucocytosis, The mean blood glucose level was 320 mg% and serum osmolality was 293 mOsm/L. There was no significant difference in the level of blood sugar and serum osmolality according to the consciousness status. Eight episodes of ketoacidosis occured in 5 cases. Three episodes developed due to discontinuance of insulin and three episodes accompanied infection. The mean blood glucose level was 495 mg% and serum osmolality was 300 mOsm/L in ketoacidosis. The consciousness cleared in average 20 hours and ketonuria disappeared in average 26 hours after the administration of insulin (average 5 units/kg of body weight). At discharge, the average dose of insulin needed was 1.2 U/kg/d. Six patients were followed from 6 months to 6 years. Two developed pulmomary tuberculosis during the period of follow up.
