Ever since the first intermediate host of Clonorchis sinensis was identified with Bulimus striatulus, it has been place to an important position in epidemics. One way to prevent Clonorchis sinensis is to exterminate Bulimus, which is itself the first intermediate host and there by to separate the life cycle of Clonorchis. In killing B. striatulus, nicotine sulfate and lindane have been chosen from insecticides which are widely used in farming areas. And then nicotine sulfate and lindane have been used to check their effectiveness in killing B. striatulus. In this experiment, the resistance of cercaria which parasites to B. striatulus has also been studied. Dipping method was used in the study. Nicotine sulfate and lindane have been used to check the mortality effect. Nicotine sulfate was used to check percentage of mortality in varied times. The existance of cercaria was tried only in nicotine sulfate. In the experiment of mortality effect of insecticides to B. striatulus and cercaria, the difference in killing rate and the resistance in different concentration and different length of time have been researched. It resulted as following: In the experiment with nicotine sulfate, the mortality increased with thicker concentration in the constant length of time. When compared the necessary liquid of nicotine sulfate and lindane in LD 50, nicotine sulfate was less used than lindane, but the mortality proved high. In the treatment to the same concentration of nicotine sulfate in different length of time, it proved that the longer period showed higher mortality. The mortality time required in LD 90 of nicotine sulfate was dependent on the concentration. And thicker concentration showed quicker effect. In the resistance of cercaria and B. striatulus to nicotine sulfate, the resistance of cercaria was proved to be stronger than that of B. striatulus.

Arthroscopy of the knee joint is an essential diagnostic procedure of the knee joint lesions because of its high diagnostic accuracy and simple procedure and high safety. We analysed in 300 cases of knee joints arthroscopy which performed in Kyung Hee University Hospital from July 1978 to June 1982. The results were as follows: 1. The diagnostic accuracy of clinical diagnosis of knee joint lesions based on arthroscopic findings was 51.0%. 2. The diagnostic accuracy of clinical diagnosis in surgically confirmed cases of knee joint lesions was 56.1% and diagnostic accuracy of arthroscopy was 90.9%. 3. In meniscal lesions, the diagnostic accuracy of arthroscopic diagnosis was 94.5%, arthrographic diagnostic accuracy was 84.9%, clinical diagnostic accuracy was 48.9% and combined accuracy of three diagnostic methods was 97.3%. 4. In cases which diagnosed as I.D.K. (Internal Derangement of Knee) in initial stage of knee joint lesions, meniscal lesions (32.8%) and ligament injuries (22.4%) were predominant lessions based on arthroscopic findings. 5. The frequency of meniscal tear were no significant difference in lateral (33.3%) or medial (36.0%) meniscus except discoid meniscus rupture. 6. 68 Cases of 300 arthroscopies (22.7%) were avoided unncessary arthrotomy through preoperative arthroscopic examination of knee joint. 7. Arthroscopy is very useful and essential not only to confirm the diagnosis but also to treatment of knee joint lesions.

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.

We report a case of epidermolysis bullosa acquisita in a 53 year-old woman who had. extreme skin fragility, trauma induced blisters and erosions usually localized to extensor site of the skin surface, and healing with scars and milia for several years. Histologic findings of perilesional skin showed normal epidermis, subepid malblister and spirsely infiltration of inflammatory cells. Direct immuncofluorescence showed depositiori of IgCi and C3 in a linear pattern along the epidermal basement, membrane in the per ilesional skin. In indirect immuriofluorescence, using 1.0M sodium chloride separated nor mal human skin as the sntbstrate, antitodies(IgG at a titer of 1:40) were bound to dermal site of the separation, indicating that the patient serum yields the reaction in or below the lamiria densa. Electronmicroscopic findings showed the roof of the blister was located. below the basal lamiria.

After aseptic or septic meningitis, some neurologic complications such as convulsions, delirium, rigidity, cerebral infarctions and cerebral hemorrhage can be developed. The cerebral infarction after meningitis is caused by arterial or venous occlusions. Involvement of small perforating arteries leads to ganglionic infarcts while severe sapsm of major vessels may lead to massive infarctions in the distribution of middle and/or anterior cerebral arteries. Cortical venous and/or dural thrombosis (especially in the superior sagittal sinus) produces typical features, including multiple areas of white matter hemorrhagic infarction. These neurologic complications are common in bacterial meningitis and very rare in aseptic meningitis. We experienced a case of cerebral infarction in MCA/ACA territory and subdural hemorrhage in occipital lobe after aseptic meningitis in 10 month-old-boy. We report a case with a brief review of related literature.
