Fifty-two patients of meniscal injury were studied in the Department of Orthopedic Surgery, Seoul National University Hospital for 5 years and 6 months from January, 1973 to June, 1978. The results were as follows: 1. Male was more affected than female (M:F = 1.4:1). And the injury of meniscus was most frequently occurred in the age group between 11 and 30 years old (65.2%). 2. Thirteen patients denied the history of trauma (25.2%). 3. Over-all positive rate of Memurray sign was 85% and arthrography was 74%. 4. Lateral meniscus was more frequently affected than medial meniscus. The most frequent type of lesion was peripheral longitudinal tear (11 cases). Discoid meniscus was found in 14 patients. 5. In follow-up study, satisfactory results were obtained in 84.3%.

BACKGROUND: This study was performed to develop a dietary self-efficacy questionnaire and to determine how dietary self-efficacy is related to selected biochemical markers and health-related quality of life in hemodialysis patients. METHODS: Participants included 172 patients who had been participating in a dialysis program for at least 6 months at two teaching hospitals. A questionnaire was used to assess socio-demographic factors, dialysis-related factors, dietary self-efficacy, and kidney disease quality of life (KDQOL). Serum levels of potassium and phosphorus and interdialytic weight gain were also measured. RESULTS: The internal reliability of dietary self-efficacy was 0.944 (Cronbach's alpha). Principal component analysis resulted in two factors, situational self-efficacy of compliance with dietary guidelines and self-efficacy of food choice. The correlation analysis showed a significant association between situational self-efficacy of compliance with dietary guidelines and serum potassium and KIDQOL. The average scores of situational self-efficacy of compliance with dietary guidelines and self-efficacy of food choice in the participants were 3.52+/-0.72 and 3.61+/-0.71 respectively. Multiple linear regression analysis showed that the situational self-efficacy of compliance with dietary guidelines was significantly associated with serum potassium level and KDQOL and self-efficacy of food choice was significantly associated with KDQOL. CONCLUSIONS: Based on our results, the developed dietary self-efficacy questionnaire may be a suitable survey tool for hemodialysis patients, which can play a role in predicting clinical indicators of patient and health-related quality of life. We recommend further research into clarifying whether the positive effects of increased dietary self-efficacy is maintained in long-term dialysis patients.

Propolis has been used as a natural remedy in folk medicine worldwide. The antibacterial, antiviral, antifungal, and antiprotozoal aspects of its antimicrobial properties have been widely investigated. However, few studies focused on its applications in dentistry. Many dental diseases are related to various microorganisms in the oral cavity. In this study, we assessed the antimicrobial activity of Korean propolis extract, collected from 6 different regions, on oral pathogenic microorganisms. The propolis samples, collected from 6 different regions (P1: Uijeongbu, P2: Ansan, P3: Hongcheon, P4: Iksan, P5: Gwangju, and P6: Sangju), were dissolved in ethanol at two different concentrations (10 and 50 mg/ml). Three oral bacteria (Streptococcus mutans, Staphylococcus aureus, and Enterococcus faecalis) and one fungus (Candida albicans) were activated in general broth for 24 hours. Microorganisms were diluted and spread onto agar plates, onto which sterilized 6 mm filter papers with or without each propolis sample were placed. After 24 hours of incubation, clear zones of inhibition were observed. All tests were performed in triplicate. The propolis samples showed significant antibacterial and antifungal activity on oral pathogenic microorganisms; in addition, low-concentration groups showed outstanding antimicrobial efficacy on the 4 different microorganisms. Among the samples, P6 had significantly higher antibacterial activity than that of the others against three different bacteria. In particular, a high concentration of P6 showed a significant antifungal effect. In conclusion, we confirmed that Korean propolis has an inhibitory effect on oral pathogenic bacteria and fungi. Therefore, we suggest the possibility of developing oral medicine and oral care products based on Korean propolis.

Heorrhage and infarct-like necrosis of anterior lobe of the pituitary gland is one of the characteristic pathologic findings of the autopsied cases of Korean Hemorrhagic Fever (KHF) patients, but there has been rare reports of hypopituitarism in patients with KHF. Recently we have experienced a patient with hyponatremia who had recovered from KHF. He was admitted to our hospital due to nausea, vomiting, and epigastric discornfort. To determine the function of the anterior pituitary gland, hormonal levels of target galnds and pituitary gland were measured, and combined pituitary stimulation test was performed. ACTH, GH, and prolactin deficiency were confirmed by combined pituitary stimulation test in this patient. There was no evidence of hypothalamic or other pituitary diseases by brain MRI. Our experience shows that KHF can be a cause of hypopituitarism and these findings should alert physicians the possibility of hypopituitarisrn in patients who had recovered from KHF.

BACKGROUND: Human hepatocellular carcinoma (HCC) is a common liver tumor and the main cause of cancer-related death. Tyrosine kinase inhibitors, such as imatinib and GNF5 which were developed to treat chronic myelogenous leukemia, regulate the progression of various cancers. The aim of this study was to confirm the anti-tumor activity of tyrosine kinase inhibitors through regulation of S-phase kinase-associated protein 2 (Skp2), an important oncogenic factor in various cancer cells, in human hepatocarcinoma SK-HEP1 cells. METHODS: Cell viability and colony formation assays were conducted to evaluate the effects of imatinib, GNF5 and GNF2 on the growth of SK-HEP1 cells. Using immunoblot analysis, we assessed change of the activation of caspases, PARP, Akt, mitogen-activated protein kinases, and Skp2/p27/p21 pathway by imatinib and GNF5 in SK-HEP1 cells. Using sh-Skp2 HCC cells, the role of Skp2 in the effects of imatinib and GNF5 was evaluated. RESULTS: Imatinib and GNF5 significantly inhibited the growth of SK-HEP1 cells. Treatment of imatinib and GNF5 decreased Skp2 expression and Akt phosphorylation, and increased the expression of p27, p21, and active-caspases in SK-HEP1 cells. In sh-Skp2 HCC cells, cell growth and the expression of Skp2 were inhibited by more than in the mock group treated with imatinib and GNF5. CONCLUSIONS: These results suggest that the anti-growth activity of tyrosine kinase inhibitors may be associated with the regulation of p27/p21 and caspases through Skp2 blockage in HCC cells.

PURPOSE: Most urologists, to our knowledge, recommend prostatic biopsy if serum prostate specific antigen(PSA) concentrations are between 4 and 10ng/ml(gray zone), even in the abscence of abnormal digital rectal examination(DRE). But the detection of prostate cancer has not been frequent in patients with negative DRE and gray zone of serum PSA. So, we investigated the detection rate of prostate cancer to evaluate the effectiveness of biopsy, and provide the clinical data which is needed to make an appropriate guideline for management in those patients in Korea. MATERIALS AND METHODS: We retrospectively reviewed 58 patients with negative DRE and serum PSA greater than 4ng/ml, in whom transrectal systemic biopsy was done between January 1, 1996 and July 31, 1998. Additionally we analysed 38 patients with negative DRE and serum PSA more than 4ng/ml in a Korean literature. We calculated the detection rate of prostate cancer in patients with gray zone of serum PSA and serum PSA greater than 10ng/ml, respectively. RESULTS: Prostate cancer was detected in 5 patients out of the 58 patients(8.6%), including 1 patient(3.7%) out of 27 patients with gray zone of serum PSA and 4(12.9%) out of 31 patients with serum PSA greater than 10ng/ml. Prostate cancer was detected in 4 patients out of the 38 patients in the literature(10.5%), including 1 patient(5.0%) out of 20 patients with gray zone of serum and 3 patients(16.7%) out of 18 patients with serum PSA greater than 10ng/ml. Combining the results of our current study with that of other Korean literature, total number of patients was 96, and 9(9.4%) of them proved to harbor prostate cancer, including 2 patients(4.3%) out of 47 patients with gray zone of serum PSA and 7 patients(14.3%) out of 49 patients with serum PSA greater than 10ng/ml. CONCLUSIONS: The detection rate of prostate cancer in Korean with negative DRE and gray zone of serum PSA is significantly lower than that in North American. Therefore it may not be effective to perform biopsy in all of those patients in Korea. Needed are Korean criteria of prostatic biopsy to detect prostate carcinoma in those patients, which can be acceptable in Korean.
