Purpose: The purpose of this study was to determine the effects of different intensity of aerobic exercise for four weeks on cardiovascular risk factors, reactive oxygen, and antioxidant enzymes in old mice. Methods: Eighteen male C57BL/6 mice age 18 months were randomly classified into the control group (n=6), the moderate intensity exercise group (n=6), and the low intensity exercise group (n=6). The training groups performed the aerobic exercise twice daily for 20 minutes, five days weekly for four weeks. Data were analyzed using descriptive statistics, analysis of variance (ANOVA), the Chi-square test, and the Tukey’s test with the SPSSWIN 21.0 program. Results: In this study, among the risk factors of cardiovascular disease, blood sugar (BS) (p=.023) and total cholesterol (TC) (p=.001) were significantly different between the moderate intensity exercise group and the control group. Additionally, there were significant differences in the reactive oxygen malondialdehyde (MDA) (p=.001), the antioxidant enzymes superoxide dismutase (SOD) (p<.001) and glutathione reductase (GR) (p=.015) between the moderate intensity exercise group and the control group. Conclusion This finding suggests that moderate intensity aerobic exercise promotes the activity of antioxidant enzymes and lowers cardiovascular risk factors in older mice.

We report a case of subclavian artery laceration caused by the removal of a pigtail pleural drainage catheter in a patient with a pneumothorax. The patient was successfully resuscitated through diagnostic angiography with subsequent balloon occlusion and primary repair of the injured subclavian artery. Although pigtail drainage of a pneumothorax is known to be safe and effective, proper insertion and removal techniques should be emphasized to reduce the risk of complications.

Mucormycosis is an uncommon opportunistic fungal infection mostly affecting immunocompromised patients and gastrointestinal mucormycosis is a rare and life-threatening. We describe a 31-year-old man with a history of idiopathic cyclic neutropenia who developed perforations of the stomach and intestine and intra-abdominal bleeding due to disseminated gastrointestinal mucormycosis after the initial operation.

Cannabinoids have been proposed to possess neuroprotective properties; though their mechanism of action remains contentious, they are posited to prevent neurodegenerative disorders, including Parkinson's disease, the pathogenesis of which has not been established. Recent studies have demonstrated that induction of proteasomal dysfunction in animal models results in a phenotype similar to Parkinson's disease. Here, we investigated the neuroprotective function of a synthetic cannabinoid-receptor agonist (WIN55.212.2) in dopaminergic neuronal death induced by a proteasomal synthase inhibitor (PSI), additionally testing the hypothesis that WIN55.212.2 modulates cytoplasmic accumulation of parkin and alpha-synuclein, a key feature of proteasomal dysfunction in Parkinson's. WIN55.212.2 protects PC12 cells from PSI-induced cytotoxicity, concomitantly inhibiting PSI-induced polyADP ribose polymerase expression and activation of caspase-3. While PSI induces cytoplasmic accumulation of alpha-synuclein and parkin, WIN55.212.2 counters these effects. Interestingly, however, while PSI induces the activation and nuclear translocalization of nuclear factor kappaB, WIN55.212.2 potentiates this effect. These data are suggestive that WIN55.212.2 might confer a neuroprotective benefit in PSI-induced proteasomal dysfunction, and could further protect against neuronal degeneration stemming from cytoplasmic accumulation of alpha-synuclein and parkin. These results indicate that WIN55.212.2 may be a candidate for treatment of neurodegenerative diseases, including Parkinson's disease.

The 5 year survival rate after surgical resection for stage III non-small cell lung cancer(NSCLC) remains short, only 10-19%. Radiotherapy seems to show some benefit for local control, but it does not reflect to prolongation of survival, as distant metastasis prevails. Vinblastine is one of the most active agent against NSCLC. 5-Fluorouracil(5-FU) and cisplatin are synergistic in anti-cancer activity in adenocarcinoma of gastrointestinal tract and squamous cell cancer of head and neck. We initiated a phase II trial for advanced NSCLC to determine the effect of FVP regimen in response rate, survival and toxicities. The therapy consisted of 5-FU 500mg/m2/12 hours continious IV infusion for 36 hours from day 1, vinblastine 3mg/m2 IV bolus day 1 and 2, cisplatin 75mg/m2 IV infusion over 2 hours day 1 and it was repeated every 3 weeks. Among the 45 patients entered into this study, 40 patients were evaluable for response. The objective response rate was 50%(CR;1/40, 2.5% PRi19/40, 47.5%). The median survival of all the patients was 42.9 weeks(8.4+ - 140.6 weeks); the responding patients survived longer than the non-responders(mediansurvival; 54.4 weeks vs 29.7 weeks, p<0.05). The toxicities of this regimen were acceptable but 1 patient died of pneumonia associated with granulocytopenia. We concluded that the FVP regimen is effective in the treatment of advanced non-small cell lung cancer and a prospective randomized trial and long- term follow up is warranted.

PURPOSE: The prognostic factors in acute lymphoblastic leukemia was patient's age at diagnosis, sex, hepatosplenomegaly, initial WBC & platelet count. Recently immunophenotype has being studied as guidance for several treatment protocol. We performed a retrospective study to evaluate the significance of immunophenotype on clinical course & long-term survival in children with acute lymphoblastic leukemia. METHODS: One hundred two children with acute lymphoblastic leukemia were admitted to the Department of Pediatrics, Yonsei University College of Medicine from Jan.1991 to Dec. 1995, and bone marrow aspiration biopsies and immunophenotyping were performed. The prognostic significance of immunophenotype was evaluated base on the median event free survival and probability of survival at the end of follow-up. RESULTS: 1) In 102 children comprised 14 cases under 2 years old, 71 cases from 2 to 10 years of age and 17 cases above 10 year old. The ratio of male to female was 6 : 4. 2) By CCG risk grouping, standard risk in 21 cases, intermediate risk in 35 cases, high risk in 46 cases. 3) By cytologic classification of FAB, Ll in 65 cases, L2 in 31 cases, L3 in 2 cases 4) Remission induction rate in early pre-B ALL was 100% (39/39), among those recurrence rate 20% (8/39). 5) Remission induction rate in pre-B ALL was 90% (26/29), among those recurrence rate 54% (14/26). 6) Remission induction rate in B-cell ALL was 33%(113), and all cases was expired during follow-up. 7) Remission induction rate in T-cell ALL was 100% (12/12)), among those recurrence rate 41% (5/12). 8) Remission induction rate in T-B mixed ALL was 71%(517), among those recurrence rate 0% (0/5), but non-remission cases was expired during follow-up. 9) Remission induction rate in Myeloid Ag(+) ALL was 83%(516), among those recurrence rate 80% (415). CONCLUSIONS: These results suggest that better result on long-term survival was observed in early pre-B ALL than in T-cell, 7-B mixed, or Myeloid antigen positive ALL and immunophenotype have prognostic impact in acute Iymphoblastic leukemia.

Although it is known that hypothyroidism can cause cardiac dysfunction, it is very hard to find a case report on sudden death due to hypothyroidism. There are only two reported cases on medline; one is about a 15-year-old girl who died suddenly of Hashimoto's thyroiditis and the other is about a 31-year-old man who also died suddenly of hypothyroidism associated with chronic lymphocytic thyroiditis. Recently we found a young woman who unexpectedly died while she was sleeping. She was diagnosed as hypothyroidism when she went to hospital about a month before she died. At autopsy there were roughly four abnormal findings; Hashimoto's thyroiditis, mild chronic active hepatitis, diverticulosis and accessory spleen. Trace of chlorpheniramine was detected in gastric remains and blood alcohol level was 0.37 percent. To our knowledge, this is the first case reporting sudden and unexpected natural death associated with hypothyroidism in Korea.
