1.The Effect on Inhibition of Raising Intraocular Pressure during Endotracheal Intubation in Man .
Korean Journal of Anesthesiology 1980;13(4):319-324
After various anesthetic inductions, the effects of tracheal intubation on mean arterial preasure(MAP) and intraocular pressure(IOP) were studied in 88 random patients who did not have any cardiovascular and ocular diseases properatively. IOP and MAP were measured with a Perkins hand held applanation-tonometer and a Cardi- 8- mini syhygmomanometer respectively. The results were as follows: 1) Both the MAP and IOP were increased in succinylcholine and pancuronium anesthetic induction groups after endotracheal intubation. 2) Rises in,both the MAP and IOP were inhibited in induced hypotensive anesthetic induction with halothane and trimethaphan. 3) The IOP was inhibited in the propranolol group. These results show the superiority of induced hypotensive anesthetic induction with halothane, trimethaphan and propranolol prior to administration for inhibition of raising intraocular pressure.

The aim of the present study was to investigate the pathophysiological etiology of osteoarthritis that is mediated by the apoptosis of chondrocytes exposed to 25-hydroxycholesterol (25-HC), an oxysterol synthesized by the expression of cholesterol-25-hydroxylase (CH25H) under inflammatory conditions. Interleukin-1β induced the apoptosis of chondrocytes in a dose- dependent manner. Furthermore, the production of 25-HC increased in the chondrocytes treated with interleukin-1β through the expression of CH25H. 25-HC decreased the viability of chondrocytes. Chondrocytes with condensed nucleus and apoptotic populations increased by 25- HC. Moreover, the activity and expression of caspase-3 were increased by the death ligand-mediated extrinsic and mitochondria-dependent intrinsic apoptotic pathways in the chondrocytes treated with 25-HC. Finally, 25-HC induced not only caspasedependent apoptosis, but also induced proteoglycan loss in articular cartilage ex vivo cultured rat knee joints. These data indicate that 25-HC may act as a metabolic pathophysiological factor in osteoarthritis that is mediated by progressive chondrocyte death in the articular cartilage with inflammatory condition.

OBJECTIVE: The purpose of this study was to evaluate the risk of cesarean section in nulliparous women who undergone induction at postterm pregnancy. METHODS: The retrospective study was conducted from March, 1997 to March, 2005 by reviewing 331 nulliparous patients more than 41 weeks' gestation delivered after induction at our Hospital. The evaluated variables to assess the risk of cesarean section were maternal age, body mass index (BMI), gestational age (GA), Bishop scores (BS), fetal body weight (FBW), fetal head circumference (FHC) and fetal sex. t-test and x2-test were used to compare these categorical variables. RESULTS: The study included 331 nulliparous singleton pregnant women undergoing elective induction for postterm pregnancy: 127 (38.4%) delivered babies by cesarean section due to induction failure, progression failure and fetal distress, whereas 204 (61.6%) delivered vaginally. The mean maternal ages were 27.59+/-2.57 in cesarean delivery group and 26.99+/-2.61 in vaginal delivery group. The average values of BMI at postterm in cesarean and vaginal delivery groups were 26.70+/-2.82 and 25.75+/-2.67 kg/m2. GA was 41.36+/-0.27 weeks in cesarean delivery group, whereas 41.20+/-0.19 weeks in vaginal delivery group. The average FBW and FHC were 3460.31+/-358.22 g and 34.59+/-1.18 cm in cesarean delivery group, compared to 3363.95+/-361.22 g and 34.03+/-1.34 cm in vaginal delivery group. CONCLUSION: The BMI, FBW and FHC have linked to the risk of cesarean delivery in nulliparous women who underwent elective induction. Thus, these information would provide the useful tools to assess the risk of cesarean section in postterm nulliparous patients for planning an induction.

The hepatoprotective activity of Acanthopanax koreanum Nakai extract (AE) was investigated against D-Galactosamine/Lipopolysaccharide (D-GalN/LPS)-induced liver failure rats compared with that of acanthoic acid (AA) isolated from AE. Although D-GalN/LPS (250 mg/kg body weight/10 microg/kg body weight, i.p.) induced hepatic damage, pretreatments with AE (1 and 3% AE/g day) and AA (0.037% AA, equivalent to 3% AE/g day) alleviated the hepatic damage. This effect was the result of a significant decrease in the activity of alanine transaminase. Concomitantly, both the nitric oxide and IL-6 levels in the plasma were significantly decreased by high-dose AE (AE3) treatment compared to the GalN/LPS control (AE0). This response resulted from the regulation of pro-inflammatory signaling via a decrease in TLR4 and CD14 mRNA levels in the liver. While a high degree of necrosis and hemorrhage were observed in the AE0, pretreatment with AE3 and AA reduced the extent of hepatocyte degeneration, necrosis, hemorrhage and inflammatory cell infiltrates compared to the AE0. In conclusion, these results suggest that especially high-dose AE are capable of alleviating D-GalN/LPS-induced hepatic injury by decreasing hepatic toxicity, thereby mitigating the TLR 4-dependent cytokine release. The anti-inflammatory effect of AE could be contributing to that of AA and AE is better than AA.

BACKGROUND/OBJECTIVES: This study investigated the antioxidant activities and hepatoprotective effects of Schisandra chinensis Baillon extract (SCE) against tert-butyl hydroperoxide (t-BHP)-induced oxidative hepatic damage in rats. MATERIALS/METHODS: Sprague-Dawley (SD) rats were pretreated with SCE (300, 600, and 1,200 mg/kg BW) or saline once daily for 14 consecutive days. On day 14, each animal, except those belonging to the normal control group, were injected with t-BHP (0.8 mmol/kg BW/i.p.), and all of the rats were sacrificed 16 h after t-BHP injection. RESULTS: Although no significant differences in AST and ALT levels were observed among the TC and SCE groups, the high-dose SCE group showed a decreasing tendency compared to the TC group. However, erythrocyte SOD activity showed a significant increase in the low-dose SCE group compared with the TC group. On the other hand, no significant differences in hepatic total glutathione (GSH) level, glutathione reductase (GR), and glutathione peroxidase (GSH-Px) activities were observed among the TC and SCE groups. Hepatic histopathological evaluation revealed that pretreatment with SCE resulted in reduced t-BHP-induced incidence of lesions, such as neutrophil infiltration, swelling of liver cells, and necrosis. In particular, treatment with a high dose of SCE resulted in induction of phase II antioxidant/detoxifying enzyme expression, such as glutathione S-transferase (GST) and glutamate-cysteine ligase catalytic subunit (GCLC). CONCLUSIONS: Based on these results, we conclude that SCE exerts protective effects against t-BHP induced oxidative hepatic damage through the reduction of neutrophil infiltration, swelling of liver cells, and necrosis. In addition, SCE regulates the gene expression of phase II antioxidant/detoxifying enzymes independent of hepatic antioxidant enzyme activity.

Epiphrenic diverticulum(traction type) is such a rare disease. The case of this disease which is due to mediastinal tumor, not because of inflammatory adhesion or of motor disorder is especially hard to find. The patient was a 50-year-old male and admitted with the intermittent postprandial chest discomfort. The chest CT and esophagography showed epiphrenic diverticulum(traction type). The tumor was located at the left anterolateral of thoracic spine, adhered to the right wall of esophagus. We performed the diverticulectomy and extirpation of mediastinal tumor under left posterolateral thoracotomy. The tumor and the esophagus were well seperated without invasion to the esophagus. In the pathology of resected tissues, solitary neurofibroma was diagnosed. There was no complication or recurrence after surgical resection.

Intrauterine contraceptive device (IUD) is the most common contraceptive method in the world, but it exists a little risk of uterine perforation and even more severe risk such as a perforation of intra-abdominal organs. In this case, the patient recognized that the previously inserted IUD was translocated but she was asymptomatic without any management. After insertion of the second IUD, she visited our hospital for lower abdominal pain. The abdominal X-ray finding and transvaginal sonography revealed one translocated IUD in peritoneal cavity and another IUD in intrauterine cavity. Thus, we report a case with the laparoscopic diagnosis of small bowel perforation by a previously inserted IUD and its removal by segmental resection of small bowel after mini-laparotomy, along with the brief review.
