This study was conducted to clarify the relationship of body fat percent with serum lipid level and blood pressure in adults. The study subjects were 472 men and l89 women who visited Multiphasic Health screening center of Yeungnam university Hospital in Taegu from May 20 to September 30, 1994. The relationship of serum lipid and blood pressure with BMl, Katsura index, atherogenic index, which calculated from the health screening data and body fat percent measured by impedance fat meter(model SIF-819) were analyzed. Three groups were classified as Group I(men: body fat percent > or= 20, women: body fat percent > or= 25, Group II (men: 15 < or = body fat percent <20, women: 20 < or = body fat percent<25, Group III(men: body fat percent <15. women: body fat percent<20) In this study, Group I accounted for 3.2%in men, 3.7%in women. Weight was significantly different among three groups in both sexes(p<0.01) and height was not significantly different among three groups. In men, serum total cholesterol, triglyceride, high density lipoprotein, low density lipoprotein. atherogenic index were significantly different(p<0.01). In women, serum total cholesterol and low density lipoprotein were significantly different(p<0.05 but there was no differences in triglyceride and high density lipoprotein among three groups. BMl and Katsura index were significantly different among three groups in both sexes(p<0.01). In men, body fat percent was positively correlated with weight, BMl, Katsura index, total cholesterol, triglyceride, low density lipoprotein, atherogenic index and systolic and diastolic blood pressures, and negatively correlated with high density lipoprotein. In women, body fat percent was positively correlated with age, height, weight, BMl, Katsura index, total cholesterol, triglyceride, low density lipoprotein and atherogenic index, and negatively correlated with high density lipoprotein. But there was no significant correlation between body fat percent and blood pressure in women. In multiple regression analysis for total cholesterol, fat percent, age and BMl were significant independent variables in men(p<0.05, R2=0.1286), and body fat percent and age in women(p<0.05, R2=0.3399). In case of LDL/HDL ratio, only BMl was a significant independent variable in men(p<0.01, R2=0.0954), and body fat percent, age and BMl in women(p<0.05, R2=0.3164). In multiple regression analysis, age, low density lipoprotein and total cholesterol were significant independent variables on systolic blood pressure in men(p<0.05, R2=0.1297), age and total cholesterol in women(p<0.055, R2=0.1705). On diastolic blood pressure, only age was a significantly independent variable in men(p<0.01, R2=0.0972) and women(p<0.01, R2=0..1218). From the result of this study, it could concluded that body fat percent was significantly associated with other obesity indices and serum lipid, but had no significant association with blood pressure. To establish the relationship of body fat percent with blood pressure, further study which consider other variables that may have an effect on blood pressure should be performed.

The purpose of this paper is to define the bacterial sources of wound infection after surgery including debridement for open fractures. Total number of patients were 123 during surgery July 1975 to Oct. 1976 at Hangang Sacred Heart Hospital. Out of 123 cases 17 were infected postoperatively. Serial bacterial cultures were performed for specimens taken from the contaminated wound in emergency room and by exposing the Petri-dishes in the operating room. Additional cultures were carried out for 17 specimens taken from the infected wounds postoperatively. Positive bacterial cultures from the initial wounds were obtained in 71 cases (57.7%) out of 123 contaminated wounds in emergency room. Setting monitoring of air contamination in conventional operating room, 51 colonies of bacterial growth per 1 hour exposure were noted and common organisms were colliform bacilli, streptococci and staphylococci in order. Postoperative wound infection rate was 13. 8%. Common pathogens were staphylococcus aureus, coliform bacilli and pseudomonas and kanamycin was most effective antibiotics. The retrospective bacteriological studies for 17 infected cases elucidated following results: 1) Organisms of same species; from initial wound and infected wound postoperatively 7 cases 2) Organisms of same species; from air contamination in the operating room and infectected wound postoperatiyely 5 cases 3) Organism of same species; from air contamination in the operating room, initial wound and infected wound postoperatively 1 case 4) Others (contagious or endogenous origin) 4 cases The results reveal that the initial contaminated open fracture and air contamination during surgery are the main sources of postoperative infection. Four cases which the infectious sources were not determined included in contagious origin dogmaticaIly.

This study was conducted to assess the effects of implementation of the patient referral system started July 1st, 1989. A comparison on the pattern of outpatient services of the Departments of Internal Medicine, General Surgery, and Pediatrics at the Yeungnam University Hospital was conducted for each one year period before and after implementation of the patient referral system. The pre-implementation period was from July 1. 1988 to June 30, 1989 and the post-implementation period was from July 1. 1989 to June 30, 1990. The information used for this study was obtained from official forms, prepared by the Yeungnam University Hospital, and submitted to the Korean Medical Insurance Cooperatives. After implementation of the patient referral system, the number of outpatient cases in the Department of Internal Medicine decreased 36.1% from 9,669 cases to 6,181 cases a year. Cases in the Department of General Surgery decreased 23.7% from 1,864 cases to 1,422 cases a year. The number of cases in the Department of General Surgery decreased 23.7% from 1,864 cases to 1,422 cases a year. The number of cases in the Department of Pediatrics decreased 36.9% from 3,372 cases to 2,128 cases a year. After implementation of the patient referral system, the average age of cases in the Departments of Internal Medicine and General Surgery was 52.5 and 49.7 years old, respcetively. This was a significant increase in comparison with the pre-implementation period. After implementation of patient referral system, the proportion of new outpatients in the Department of Internal Medicine decreased form 24.1% to 14.6%, the Department of General Surgery from 36.0% to 23.4%, and the Department of Pediatrics from 15.5% to 8.3%. The number of visits per case decreased significantly in the Department of Internal Medicine(from 1.74 to 1.61), but there was no significant change in the Department of General Surgery and Pediatrics. The length of treatment per case increased significantly in all three departments (form 16.1 days to 19.3 days in the Department of Internal Medicine, from 12.0 days to 15.2 days in the Department General Surgery, and 8.9 days to 11.2 days in the Department of Pediatrics). The number of clinical tests per case increased significantly in the Department of Internal Medicine (from 22. to 2.5), in the Department of Pediatrics(from 0.8 to 1.1) and increased in the Department of General Surgery(from 6.4 to 6.6). The average medical cost per case decreased form 43,900 Won to 42,500 Won in the Department of Internal Medicine, while the cost increased from 75,900 Won to 78,500 Won in the Department of General Surgery and from 12,700 Won to 13,500 Won in the Department of Pediatrics. In case-mix, the chronic degenerative disease(i. e. hypertension, diabetes mellitus, angina pectoris, malignant neoplasm, and pulmonary tuberculosis) ranked higher and acute infectious diseases and simple cases(i. e. gastritis and duodenitis, haemorrhoids, anal fissure, carbuncle, acute URI, and bronchitis) ranked lower after implementation of the patient referral system compared to before implementation.

BACKGROUND: The high level of susceptibility of patients with liver cirrhosis (LC) to septicemic infection is thought to be due to decreased reticuloendothelial function and irnpairment of several components of cell mediated and humoral immunity. It is well known that LC may cause many characteristic skin changes including jaundice, spider angioma, palmar erythema, xanthelasrna and nail changes such as clubbing and white nails. OBJECTIVE AND METHODS: During a 7 month period frorn April to October 1995, 100 patients who had been diagnosed as having LC were evaluated for the duration of their LC, the associated diseases they had apart from LC and various skin manifestations. Also, we performed the tuberculin test in 20 patients with LC and evaluated the correlation of the tuberculin test with severity of LC divided into 3 groups according to the Childs classification. RESULTS: The results are summarized as follows ; 1. The most frequent duration of LC was under 5 years (74%). 2. The most common associated disease of patients with LC was upper GI bleeding including esophageal varix (24 cases). Also, diabetes mellitus (13 cases) and hepatic coma (11 cases) were observed. 3. Jaundice (82 cases) was the most frequent skin rnanifestation of patients with LC. In addition, vascular changes (81 cases) and various nail changes (69 cases) were observed. Onychomychosis was the most common nail change of patients with LC. 4. 60% of the patients who were given the tuberculin test showed anergy, and the frequency of anergy increased in proport on to the severity of LC. However, it was not significant statistically (p> 0.05 ). CONCLUSIONS: Some of the skin manifestations help in the diagnosis of LC. Also, increased frequency of tuberculin test anergy in proportion to the severity of LC is thought to be related to decreased cell mediated immunity, although statistically it is not significant.

BACKGROUND: Generally, there are few problems in the diagnosis of Paget's disease(PD) using the H&E stain. However, the differentiation of PD from the clonal type of Bowens disease and superficial spreading melanoma in situ that shows pagetoid spreading of tumor cells, may present diagnostic difficulties. In addition, the specia1 stains used for demonstrating the presenee of Pagets cells, such as PAS and mucicarmim, are non-specific and not always sensitive. So, inenunohistochemical stains with monoclonal antibodies against various antigens may be helpful for differentiating PD from ather morphologically similar skin lesions. OBJECTIVE: The purpose of this study was to investigate the diagnostic accuracy of immunohisto- chemical staining for diagnostic use in PD. METHODS: Immunohistochemical stains used in the biotin streptavidin amplificxl technique with monoclonal antibodies to several low rnolecular weight cytokeratin(CK)s, EMA and CEA, were performed on formalin-fixed, paraffin-embedded tissue. Twelve cases of PD(10 cases of extranmmmary PD and 2 cases of mammary PD), five cases of superficial spreading melanoma in situ and five cases of Bowens disease were investigated. RESULTS: The results were as follows. 1. Positive reactions with variable intensity using CK7, CKS, CK19 were seen in all cases(100%) of PD and the. staining intensity tor CK7 or CK19 was stronger than that of CKS. 2. Of the 12 cases of PD, both CK18 and CAM5.2 staining showed positivity in 11 cases(92%). 3. EMA and CEA staining showed positivity in 10(83%) and 9(75%) of 12 cases, respectively. 4. Some Pagets cells were negative for CK8, CK18 and EMA, although other positive cells were observed in the same sections. 5. All antigens were consistently negative in all cases of Bowens disease and superficial spreading melanoma in situ. CONCLUSION: The results show that moaoclonal antibodies to low molecular weight CKs are more sensitive than EMA or CEA in the demonstration of Pagets cells. Moreover, among the low molecular weight CK series, CK7 and CK19 are most useful for their high sensitivity and intensity.
