Some species of mesophilic bacteria in the genus Aeromonas were isolated from a snakehead (Channa argus) culture-pond in the Myung-Ji area, a freshwater culture-pond in Pukyung National University, and seawater near the sewage treatment plant in Kwang-An Beach in Pusan. They were identified by biological characteristics, and their susceptibility to ten antibiotics including ampicillin, cefoxitin, ceftazidime cephalothin, cefotiam, chloramphenicol, nalidixic acid, rifampin, cefoperazone-sulbactam, and imipenem, was also studied. Four species in the genus Aeromonas, A. veronii biovar sobria (27 strains), A. caviae (14 strains), A. trota (1 strain), and A. schubertii (1 strain) were identified. A. trota, an unrecorded species in Korea, is reported for the first time in this study. Three strains of A. veronii biovar sobria showed multiple resistance to three kinds of antibiotics and one strain to four drugs. All strains of A. caviae were resistant to more than three drugs and seven strains to four drugs. A. trota was resistant to cephalothin and rifampin, but A. schubertii showed multiple resistance to ampicillin, nalidixic acid, and rifampin.

BACKGROUND: Metabolic syndrome increases the risk for cardiovascular diseases and type 2 diabetes mellitus. Many studies have revealed that eating frequency influences the total serum cholesterol level, glucose tolerance and obesity. Hypothesizing that an increase in eating frequency decreases the prevalence of metabolic syndrome with total energy intake adjusted, we evaluated the association between eating frequency and the risk of metabolic syndrome in Koreans aged more than 20 years old. METHODS: We used the data from the 2005 Korean National Health and Nutrition Examination Survey. Metabolic syndrome was defined according to the National Cholesterol Education Program Adult Treatment Panel III and the Asia-Pacific regional obesity guidelines. To examine the association of metabolic syndrome with eating frequency, snack frequency and meal frequency, we performed multiple logistic regression analysis adjusting for age, sex, physical activity, daily caloric intake, smoking and drinking. RESULTS: Meal frequency was associated with metabolic syndrome in the 20-45 years group (P=0.011). Eating frequency was significantly related with metabolic syndrome in the group aged more than 45 years (P=0.025). Within the subgroup of subjects more than 45 years who had one or two meals a day, snack frequency showed a significant association with metabolic syndrome (P=0.038). CONCLUSIONS: These results suggest that a decreased eating frequency is associated with a risk of metabolic syndrome, although the causal relationship is not exactly known. It would be useful to pursue this question through further studies.

A case of right ovarian vein syndrome is reported with a review of literature. The patient presented was a 29 year-old multipara and eighth month of pregnancy. The extirpation of entire right ovarian vein, including it's all tributaries produced a good result and has not caused interruption of pregnancy. The clinical situation due to aberrant right ovarian vein is probably more frequent than heretofore suspected, by reason of a frown of X-rays during pregnancy and also an unawareness of the condition. Therefore, if clinical observations and X-ray studies are performed, more cases of such a condition. will be expected.

Cirsoid aneurysm of the calp is a congenital arteriovenous malformation which is the result of abnormal connections betwe:.n the external carotid artery and scalp veins with a subsequent dilatation of vascular channels nd formation of aneurysm. We report a case of cirsoid aneurysm of the scalp on the left parieto-occipital area of 14-year-old female who had had 8 x 5 x 0.8 cm sized pulsating soft mass for 2 years. 4 vessel angiog raphy revealed a arteriovenous malformation that emerge mainly from a superficial temporal artery and occipital artery of the left external carotid artery and partially from the right superficial temporal artery and drined into the left scalp vein. The mass was removed by excision with ligation of the feeding arter es and followed up for 2 years without recurrence.

We reported on a rare case of recurred macrodystrophia lipomatosa of the foot, and reviewed the literature. A 62-year-old male patient presented with right foot second toe pain; preoperative magnetic resonance imaging and radiograph examination was performed. After surgery the biopsy confirmed the diagnosis. American Orthopaedic Foot and Ankle Society score was checked before and after surgery. Wide excision of the affected area including ray amputation is an effective way to prevent recurrence and relieve the pain after surgery. The 2nd toe ray amputation was performed in the treatment of recurred macrodystrophia lipomatosa of the foot, and is thought to be an effective way to relieve pain and prevent recurrence. After minimally invasive surgery with complete excision surgery, additional data on recurrence and pain relief rate are needed.

Human assisted reproductive technology programs have been being developed marvelously during this decade. However, implantation rates following embryo replacement remain low, regardless of increased fertilization rates by ICSI. One proposed possibility limiting the successful implantation is an impaired hatching caused by suboptimal culture conditions. As to improve the hatching potential of blastocysts, assisted hatching by an artificial alteration of zona pellucida(ZP) have been done in many laboratories using the various methods. We tried to investigate whether the supplementation of proteases into culture media has any effect on development, zona structure, and/or hatching of mouse embryos. Supplementation of either pronase E(PE) or proteinase K(PK) in culture media did not affect development up to blastocyst but significantly increased hatching rate. And we observed the alteration of ultrastructure and casein binding properties of ZP in mouse embryos. Also we investigated the effects of protease on development of human embryos and pregnancy rates in human ART program. From July 1994 to December 1996, 792 cycles(for study I) and 1095 cycles(for study II) undergoing the IVF-ET program in MizMedi Hospital were randomly selected for BAH. The concentrations of proteases used in this study were 1microgram/ml PE, 0.1microgram/ml PK and 1microgram/mlPE+0.1microgram/ml PK in HTF with 0.5% human serum albumin(HSA), and in vitro fertilized embryos were cultured for 24 hours. We analyzed the efficiency and stability of biochemical assisted hatching(BAH) according to the clinical profiles of patients and fertilization methods. After cultured in HTF with proteases for 24 hours of human embryos, the thinning in zona pellucida of embryos was observed but its development was not disturbed. Also, clinical pregnancy rates were higher in the PE, PK and PE+PK groups than the control group without proteases(36.0%(32/89), 35.3%(36/102), 35.1%(39/111) vs. 25.5%(125/490), p<0.05). The live birth rate in the PE, PK and PE+PK groups were increased than control, and the abortion rate were not different. They were showed a effect and safety of proteases treatment in human embryos. We selected PE as BAH for study II because of slightly better embryonic morphology and pregnancy rate. In patients over 35 years old, clinical pregnancy rates of the BAH group was higher than that of the control group(31.4%(58/185) vs. 22.2%(51/230); p<0.05). And in the cases with few oocytes retrieval, or less than 3 cycles of IVF-ET, clinical pregnancy rates of the BAH group was significantly higher than that of the control group(36.8%(86/234) vs. 27.2%(93/342), p<0.05; 36.8%(148/402) vs. 29.9%(168/562), p<0.05). In BAH groups, the clinical pregnancy rate was similar between conventional IVF and ICSI group. From above results, it is suggested that improved hatching by protease treatment is due to physiological alteration of ZP structure, giving rise to the similar hatching process to that in vivo. We suggest that BAH using protease is a simple, safe and economic technique compared to the other known assisted hatching techniques in human ART program.

OBJECTS AND METHODS: In order to evaluate the relationships between drinking habits and biological and psychosocial characteristics, the authors administrated the questionnaires about drinking patterns and acute physiological and psychological responses after drinking, several psychological scales and ethanol patch test to 94 male medical students in Chosun University. RESULTS: 1) Low consumer group had significantly more severe physiological repondents after drinking in family members than high consumer group(p<.005). 2) Low consumer had significantly more severe acute physiological responses(p<.005) and high consumer group revealed more positive psychological responses after drinking(p<.005). But there was no difference in the degree of negative psychological responses between tow groups. 3) High consumer group had significantly more extroversion tedency(p<.01) and recieved more financial support from family than low consumer group(p<.01). 4) In the results of ethanol patch test. low consumer group showed more positive skin reaction in three test occasions than high consumer grou(p<.005). 5) Also the high consumer group revealed higher scores in factor 1,2,4(alpha=0.005), and 3(alpha=0.01) in comparison of factors of Korean Alcohol Use Inventory. 6) In comparison of drinking habits, low consumer group revealed higher incidence of nearly non-drinkers and sublimatory drinkers. But there were more casulal social drinkers, selcontrolled social drinkers, impusive-binge drinkers, and habitual-excessive drinkers in high consumer group(p<.005). And in drinking patterns, the items of dependence and duration of drinking, daily drinking disposition, preferential beverage, average and maximum drinking amount of each liquor, and magnitude of sips taken were higher in high consumer group. Only one item of interval between sips was longer in low consumer group(p<.005). 7) In comparison of sociodemographic variables, there were more students who were smokers(p<.01), from larger cities and small family(p<.05), and whose parents were well educated(p<.05) but had worse marital realtionship(p<.05) in high consumer group. CONCLUSEION: For better explanation of the etiology and characteristics of alcoholism, we investigated the differences in various aspects between low alcohol consumers and high alcohol consumers in college students. The most evident differences lied in the degree of acute physiological reaction and positive rates of ethanol patch test that strongly suggested the relations with the activty of ALDH. Some differences in psychosocial aspects between two groups were noticed but could not appropriately be explained at this time.
