The purpose of this study was focused on the degree of work intensity and optimal race pace in rowing for Korean national male and female rowers. The items in physique were body height and body weight. Body density was estimated from the sum of two skinfold using the regressional equations suggested by Nagamine et al.(1972). Percent fat was calculated by Brozek et al.(1963) formular. Somatotype was calculated by Health-Carter(1981) anthropometric somatotype method. Maximal oxygen uptake measurements were continued while the work load increased by a uniform amount each 40m/4min for male and 30m/4min for female on the treadmill ergometer. The grade was constant at 0% and the initial speeds were 160m/min for male rowers and 120m/min for female rowers. Heart rate was recorded continuously all through the experiment of actual rowing by using telemetering method(Hart Check 108 System). Oxygen uptake in percent of maximal oxygen uptake(% of VO₂max) of the actual rowing was calculated from the equation of relationship between heart rate and oxygen uptake obtained during exhaustive running test on the treadmill. Heart rates during the exercise of actual rowing was measured on 8 male and 4 female Korean national rowers. Blood lactate concentration measurements were used autoclix Lancet Method after actual rowing exercise for 8 male rowers. Also, eleven male rowers and six female rowers volunteered as subjects in this study. The results obtained are summarized as follows. 1. The means for the percent fat of the Korean national male and female rowers were 12.1±1.09% and 18.4±3.50, respectively. 2. The means for Health-Carter somatotype of the Korean national male and female rowers were 2.8-4.5-2.9 of balanced mesomorph and 4.2-3.4-2.9 of mesoendomorph, respectively. 3. The means for the maximal oxygen uptake(VO₂max) of the Korean national male and female rowers were 5.30±0.607ℓ/min(65.6㎖/㎏/min) and 3.22±0.148ℓ/min(48.1㎖/㎏/min), respectively. 4. The means for the heart rate of national male and female rowers by actual rowing exercise were 171.3±10.44bpm ad 172.9±8.35bpm, respectively. 5. The means for the heart rate in percent of maximal heart rate(%VO₂max) of national male and female rowers by actual rowing exercise were 88.6±8.12% HRmax(81.7±11.12%VO₂max) and 88.2±5.38%HRmax(88.8±5.77%VO₂max), respectively. 6. The means for the RMR(Mets) of national male and female rowers by actual rowing exercise were 17.2±2.59RMR(15.4±2.12Mets) and 13.5±1.95RMR(12.2±1.44Mets), respectively. 7. The means for the pitch rate of national male and female rowers by actual rowing exercise were 31∼33 stroke/min and 29∼31 stroke/min, respectively. 8. In actual 2,000m rowing exercise, blood lactate concentration was 6.74±0.854mM/ℓ on goal in-point and 7.07±0.989mM/ℓ on 5 minutes after recovery in male rowers.

The purpose of this study was focused on the characteristic of body composition, somatotype and ?? for Korean adult males. Subjects were 7 adult males, aged 31 to 36 years (mean age ; 34.4Yrs). The items in physique were body height and weight. Body density was estimated from the sum of two skinfold using the regressional equations suggested by Nagamine et al.(1972). Percent fat was calculated by Brozek et al.(1963) formular. Somatotype was calculated by Health-Carter(1981) anthropometric method. Monark frictional bicycle ergometer was used to measure heart rate responses to ?? test. The mixed progressive loading method was adopted for bicycle ergometer. The following results of the measurement were obtained. 1. The mean for the percent fat of Korean adult males was 19.8±9.58%. 2. The mean for the Health-Carter somatotype of Korean adult males was 5.1-6.2-1.5 of endo-mesomorph. 3. The mean for the ?? of Korean adult males was 664.3±120.99kpm/min. 4. Correlation coefficients between ?? versus %fat, LBM per Height and endomorphic component were -0.49, -0.49, -0.50, respectively. 5. Correlation coefficients between ?? Versus LBM and LBM per Height were 0.45, 0.54, respectively. 6. Colleration coefficients between ?? versus mesomorphic component and ectomorphic component were -0.19, 0.26, respectively.

Objective of this study was to determine the prevalence and kinds of complementary and alternative medicine (CAM) used in cancer patients. Questionnaire survey was done by trained interviewers for use of CAM, demographic information, type of cancer and cancer stage for 512 cancer patients in 7 general hospitals in Seoul. Among the cancer patients, the total number of inpatients was 315 and outpatients 197. The results were as follows. Among cancer patients, 55.5% of them used CAM. The patients who were 30's and 40's showed high rate of CAM use(59.2%, 64,7%). Stomach cancer patients showed highest rate of CAM use(75.6%) among cancer patients. Liver cancer and breast cancer patients also showed high rate of CAM use(71.1%, 60.3%). The patients received chemotherapy showed higher rate of CAM use(60.6%) than the patients not received chemotherapy(43.7%). By multiple logistic regression, stomach cancer, liver cancer, and chemotheray were statistically significant variables for use of CAM. Among cancer patients, the use of herbs was highest(86.0%), followed by diet(46.5%) and chinese medicine(14.1%). Elm tree was the most frequently used(49.6%), however, total usage of mushrooms such as Sang-Whang, Young-Gee, Agaricus, Wooon-Gee were 57%. The number of CAM items used by cancer patients were limited and it is necessary for scientific data to prove the their effect.

Heme oxygenase-1 (HO-1) is an anti-oxidant enzyme normally upregulated in response to oxidant injury. Here we determined the role of HO-1 in podocyte apoptosis in glomeruli of streptozotocin-treated rats and in immortalized mouse podocytes cultured in media containing normal or high glucose. HO-1 expression, its activity, the ratio of Bax/Bcl-2 protein, and active caspase-3 fragments were all significantly higher in isolated glomeruli of diabetic rats and in high glucose–treated podocytes. These increases were inhibited by zinc protoporphyrin treatment of the rats or by HO-1 siRNA treatment of the podocytes in culture. The number of apoptotic cells was also significantly increased in the glomeruli of diabetic rats and in high glucose–treated podocytes. Inhibition of HO-1 accentuated the increase in apoptotic cells both in vivo and in vitro. Our findings suggest that HO-1 expression protects against podocyte apoptosis under diabetic conditions.

Hemorrhagic complications in patients with end stage renal disease (ESRD) are common. These abnormal bleeding tendencies are caused by several factors including anticoagulation during hemodialysis, anemia, and uremic platelet dysfunction. The most common clinical manifestation of uremic bleeding is hemorrhage of the gastrointestinal tract from gastric ulcer disease. Mediastinal bleeding, however, is rare in ESRD patients. Here, we report a case of spontaneous mediastinal bleeding in a patient with hemodialysis. A huge periesophageal hematoma was observed on the chest CT scan and the bleeding time representing platelet function was prolonged. This case underlies the diversity of uremic bleeding.

The schwannoma is a benign neoplasm originating from Schwann cell. Solitary nerve sheath tumors such as benign schwannomas arising in the pelvic retroperitoneum are infrequently reported. Those tumors can indeed be misdiagnosed for other more common conditions both clinically and instrumentally. We report a very rare case of a benign retroperitoneal pelvic schwannoma of the obturator fossa, which was incidentally found and misdiagnosed as adnexal mass preoperatively in fifty one-years-old postmenopausal women.
