Malignant hyperthermia is the disorder of calcium regulation within skeletal muscle associated predominantly with anesthesia. It is triggered by volatile anesthetics and depolarizing neuromuscular blocking agents. We experienced a case of malignant hyperthermia. 50 years old female patient was transferred to our emergency room that she was developed tachyarrhythmia and high fever. She was taken arthroscopic examination under the general anesthesia with enflurane and succinylcholine. We suspected malignant hyperthermia and promptly treated her with dantrolene sodium. She was developed disseminated intravascular coagulopathy and acute renal failure then we were intensive care to her. She was discharged without sequela. We experienced successful management of malignant hyperthermia.

Objectives : We evaluated the efficacy of ramosetron and ondansetron for preventing postoperative nausea and vomiting (PONV) in laparoscopic colectomy. Methods and Materials : Eighty patients who received laparoscopic colectomy were randomly divided into two groups: R group (ramosetron 0.1mg PO) and O group (ondansetron 4mg twice IV). Injection or oral medication was administered before the induction of anesthesia in each group. Injection was administered at the end of surgery in O group. General anesthesia was induced using propofol and rocuronium, and maintained with sevoflurane, remifentanil and air (FiO2 0.5), We investigated the incidences of PONV in each group by the Rhodes index of nausea, vomiting and retching (RINVR) at postoperative 6 and 24 hours. Results : The incidence of PONV was not different between group at each time points after surgery (at postoperative 6 hours: 20% in group R, 17.5% in group 0, at postoperative 24 hours; 12.5% in group R, 7.5% in group 0). There was no difference in the severity of PONV, satisfaction, rescue drug usage. Conclusion : Prophylactic therapy with ramosetron is as effective as conventional prophylactic therapy with ondansetron for preventing PONV in general anesthesia for laparoscopic colectomy.

Objective : There are controversies in pnmmg technique of rocuronium whether it can or can't shorten the onset time. We want to compare the effects of two different priming doses and intervals of rocuronium. Materials and Methods : After giving propofol, 50 patients were randomly assigned to 5 groups. Group I received a placebo, followed 3 min later by rocuronium 0.6 mg/kg. Priming doses and intervals of Group II, Ill, N, V were 0.06 rng/kg and 2 min, 0.12 mg/kg and 2 min, 0.06 rug/kg and 3 min, 0.12 mg/kg and 3 min, respectively. Total dose of rocuronium was 0.6mg/kg. Train of four (TOF) count or ratio and 1st twitch height of TOF (T1) were monitored with 15 secondsintervals. TOF ratio of each groups just before bolus injection, duration for TOF count to reach zero and duration for Tl to reach 95% depression after bolus injection were compared. Results : Duration for TOF count to reach zero and duration for Tl to reach 95% depression after bolus injection were decreased in priming groups compared to Group 1 (P < 0.01) In group V, significant depression of TOF ratio just before bolus injection was seen (P < 0.05). Conclusion : Priming technique with rocuronium is effective method to shorten the onset of neuromuscular block. But priming dose of rocuronium itself could cause hypoxia and aspiration in awake patients and should be used carefully. Priming dose of rocuronium 0.06 mg/kg and 2 minutes interval maybe relatively safe method.

Background & objectives : An increase of calcium influx during alcohol withdrawal state may contribute to neuronal hyperexitability, which cause delirium tremens(DT). Some investigators have found calcium channel blockers effects in prevention of DT in experimental animals. Therefore we evaluated the preventive effects of calcium channel blocker(nimodipine) and benzodiazepine(chlordiazepoxide) on the development of DT in alcohol withdrawal seizure(AWS) patients. Method : A total 59 patients with AWS were divided into three groups according to the management nimodipine-treated, chlordiazepoxide-treated, and control(no specific medication) groups. We compared the incidence rates of DT in the three groups. Results : Total incidence rate of DT was 30.5%(18 of 59 patients). There were 6 DTs of 18 patients(33.5%) in nimodipine-treated group, 4 of 21 patients(22.5%) in chlordiazpoxide-treated group, and 8 of 20 patients(44.0%) in control. Conclusion : The control group(44.0%) showed the highest incidence rate of DT. And nimodipine-treated(33.5%) and chlordiazepoxide-treated group(22.5%) were followed. However, this result failed to demonstrated statistically significant differences due to small numbers size.

The colorectal corcinoma is one of the most common malignant tumor in Korea and its carcinogenic mechanism has not been elucidated exactly yet. So far, the most common carcinogenic mechanism has been known to be multiple genetic changes. But, the CpG island hypermethylation has been revealed to be one of the most important carcinogenic mechanism second to the genetic changes. The epigenetic changes characteristically imprint and transfer to the next generation without changes of nucleotide sequences. When the CpG island of promoter or 5'- exon 1 of a specific gene is methylated by DNA methyltrasferases (DNMTs), the gene expression is inhibited. Carcinogenic mechansisms by promoter methylation has been well known, but the progression of the cancer has not been elucidated yet. The molecular researches on the carcinogenic mechanisms largely depended on the tumor tissue containing various components of cell, due to difficulties in harvesting pure homogeneous tumor cells. Promoter methylatonof the cancer related genes as APc, hMLH2, p16, DAP-K and MGMT in 50 cases of sporadic colorectal carcinoma was studied. The pure normal colorectal epithelial cells, and cancer cells from superficial and deep invasive portion were harvested respectively by laser captured microdissection(LCM), and DNA was extracted from them. The promoter methylation was studied by methylation specific poymerase reaction (MSP) after bisulfite modification of the DNA and the expression of the genes by immunohistochemistry. The results suggests that promoter methylation of the cancer related genes are closely related with the colorectal carcinogenesis and it occurrs from early phase of carcinogenesis, progressing constantly to the late stage. And the promoter methylation of normal epithelial cells increased by age. The p15, known to be the genes related to hematologic malignancy, was closely related to the colorectal carcinoma as well.

Splanchnic neurolytic block(SNB) with alcohol improves the management of pancreatic cancer pain. Adverse effects of alcohol SNB which include regional pain, hypotension, diarrhea, and acute alcohol intoxication are common, but acute hepatitis caused by alcohol neurolytic block is rare. A 63-year-old patient with pancreatic head cancer and liver metastasis had complete pain relief after both retrocrural tansdiscal SNB with 100% alcohol 10 ml. But, 1 day later, liver function test showed a high elevation in the aspartate aminotransferase (AST, 2182 IU/L) and alanine aminotransferase (ALT, 1807 IU/L). The patient had slight jaundice, general weakness, chilling, nausea and vomiting after SNB. Both AST and ALT decreased to 46 and 119 IU/L within 10 days with only supportive therapy. But, 19 days later, the patient died due to pneumonia. Our case illustrates the importance of clinical surveillance especially in patient with hepatic disease after alcohol SNB.

To investigate the effect of high dose irradiation on the Vickers hardness number(VHN), color change and wear rate of dental filling materials, esthetic filling material specimens were studied. Six kinds of composite resins and two kinds of glass ionomers(GI) were used. One(CLF) was chemically cured composite resin, and five(HCX, HPL, PHB, POF, PRT and RZI) were light cured composite resins. One(FJT) of GI was chemically cured GI and one(FLC) was light cured GI. The filling material specimens were made according to the manufacture's instructions and were finally polished with Microcloth(Buehler). Half of the specimens were irradiated with 100 Gy radiation using a linear accelerator(Mitsubishi, 6 MV). VHN and CIELAB color were measured before and after irradiation, and wear test were performed for nonirradiated specimens by brushing with toothpaste, From the experiment , the following results were obtained. 1. The CIELAB color difference was significantly different depending on the material(p<0.01), and FLC showed the highest color difference (CIELAB ΔE) of 9.452 and CLF showed the lowest value of 3.642. 2. The VHNs of nonirradiated specimens were 12.22∼73.58 and those of irradiated specimens were 25.53∼84.53. The VHNs of irradiated specimens were significantly higher than those of nonirradiated specimens(p<0.05) except RZI, FJT and FLC. 3. The wear rate of irradiated specimens of RZI, FLC were significantly lower than those of nonirradiated specimens(p<0.05). 4. The color difference after brushing of irradiated specimens were higher than those of nonirradiated specimens except CLF.
