A 29 kDa cysteine protease of Taenia solium metacestodes was purified by Mono Q anion-exchanger and Superose 6 HR gel filtration chromatography. The enzyme was effectively inhibited by cysteine protease inhibitors, such as iodoacetic acid (IAA) and trans-epoxy-succinyl-L-leucyl-amido (4-guanidino) butane (E-64) while inhibitors acting on serine- or metallo-proteases did not affect the enzyme activity. The purified enzyme degraded human immunoglobulin G (IgG), collagen and bovine serum albumin (BSA), but human IgG was more susceptible for proteolysis by the enzyme. To define the precise biological roles of the enzyme, more detailed biochemical and functional studies would be required.

Among the erythrocyte membrane defects, hereditary spherocytosis is the most common. The erythrocyte membrane defect results from a deficiency of spectrin, the most important structural protein in red cell. Hereditary spherocytosis often presents with hemolytic anemia, jaundice, moderate splenomegaly. Diagnosis is established by the presence of spherocytes in the peripheral blood, reticulocytosis, an increased osmotic fragility, and a negative Coombs test. In children, splenectomy is usually performed after age 6 years but can be done at a younger age if warranted by the severity of the anemia and the need for frequent transfusions. In the period December 1987 to Agust 1993, 9 patients with hereditrary spherocytosis underwent splenectomy and the following results were obtained. 1. Nine patients were comprised of five males and four females. 2. Five patients(55.6%) had been admitted to our hospital during age 6-10 years. 3. Four of the nine patients had autosomal dominant inheritance with variable expression. The other five patients had no known inheritance. 4. The diagnosis of the spherocytosis was based on the increased osmotic fragility and increased autohemolysis of the erythrocytes, as well as on the appearance of spherocytes in the peripheral blood smear. 5. In all cases splenectomy was performed. Two patients had concomitant gall stones and choledocholithiasis, respectively. One patient with concomitant gall stones underwent simultaneous cholecystectomy and splenectomy. The other patients associated with choledocholithiasis underwent splenectomy, cholecystectomy, choledocholithotomy, and T-tube drainage. 6. Complete hematologic recovery was obtained by the splenectomy in all cases. 7. Postoperative complication was not occurred.

PURPOSE: The minimally invasive technique in urologic treatment such as percutaneous cyst aspiration with sclerotherapy is increasing in recent years to treat symptomatic simple renal cyst. However, this method has a high recurrence rate. The laparoscopic approach can be an alternative method which is far less invasive than open surgery and less recurrence rate than sclerotherapy. Furthermore, the retroperitoneal approach can avoid unnecessary intraperitoneal manipulation and thereby reduce complications such as injury and adhesion of the bowel. We evaluated the recurrence rate, hospital stay, and postoperative morbidity of retroperitoneal laparoscopic marsupialization of simple renal cyst. MATERIALS AND METHODS: From July 1996 to May 1997, 27 patients(male 7, female 20) with simple renal cyst, presenting with pain(14 patients), recurrent cyst after percutaneous aspiration(9), and incidentally found renal cyst(4) was managed with retroperitoneal laparoscopic marsupialization of simple renal cyst. Mean patient age and cyst size were 50 years(range 35-66 years) and 7.8cm(range 3.0-12.0cm), respectively. RESULTS: Mean operative time, hospital stay, and follow-up period were 58.9 minutes(range 40-110 minutes), 2.3 days(range 1-4 days) and 14.2 months(range 6-25 months), respectively. There was no recurrence and cytologic and pathologic examinations were benign in all patients. There was no significant difference in the operative time according to the position and the side of the renal cyst. CONCLUSIONS: Retroperitoneal laparoscopic cyst marsupialization is an effective therapy for recurrent or symptomatic large simple renal cyst with low recurrence rate and postoperative morbidity.

This study was designed to detect and evaluate an antigenicity of low molecular weight proteins of Fasciola hepatica in fascioliasis. Low molecular weight protein of F. hepatica was purified by ammonium sulfate precipitation and Sephacryl S-100 HR gel filtration. The protein obtained was estimated to be 8 kDa on 7.5-15% gradient sodium dodecyl sulfate gel electrophoresis. Immunoblotting studies showed that the 8 kDa protein reacted with human fascioliasis sera, but not other trematodiasis sera. This result suggests that the 8 kDa protein of F. hepatica is one of diagnostic antigens in human fascioliasis without cross-reaction with other human trematodiasis.

BACKGROUND: Left ventricular hypertrophy (LVH) has been shown to be an independent risk factor for cardiovascular morbidity and mortality. The combination of hypertension and obesity are well known to act as risk factors of left ventricular hypertrophy in a number of studies, but it is unclear whether obesity itself stimulates LVH independently. Therefore, we investigated the relationship of left ventricular mass to body size in normotensive adults. METHODS: A population sample of 240 normotensive (systolic BP < 140 mmHg and diastolic BP < 90 mmHg) adults (139 men and 101 women) was examined by echocardiography. We excluded adults with history of hypertension, thyroid diseases, diabetes mellitus and other cardiac diseases. Left ventricular mass normalized for height(2.7) was used in the analyses and left ventricular hypertrophy was defined as a value of 50 g/m(2.7) men or 47 g/m(2.7) in women. RESULTS: Left ventricular mass significantly and positively correlated with body mass index. On univariate correlation analysis after adjusting for age, the body mass index was associated with LV mass/height(2.7) (LVMI: Left Ventricular Mass Index) in males and body mass index, waist circumference, hip circumference and waist/hip circumference ratio were associated with LVMI in females. Left ventricular hypertrophy was more frequent in overweight (33.3%) and obese (39.4%) groups than in lean group (15.9%). CONCLUSION: Left ventricular mass was strongly related to obesity in normotensive adults, especially in females. Obesity may be an independent risk factor for left ventricular hypertrophy.

BACKGROUND: Recently, the trend pursuing slimness is significantly increasing in adolescents. Because of distorted body image, excessive body weight control can cause problems of health. The goal of this study is to investigate the factors of distorted body image and its problems. METHODS: The survey was performed in a high school of Jindo island on May, 2000. All of 258 students in 1st and 2nd grade participated in this study by questionnaires. Thirteen truthless questionnaires were excluded in this study. Therefore 245 student were selected. RESULTS: Only 20% of 245 repliers were satisfied with their body figure. In male, 24.1% wanted weight loss, and 39.8% wanted weight gain. In female, 73% wanted weight loss. In a populations(BMI<20), 70 males wanted weight loss, whereas 35(52.2%) among 67 females want weight loss. According to these result, female stuedents wanted strongly weight loss than male. The factors which most influenced body figure were sports star in males(36.1%), and movie stars in female.(43.8%) A group of 58.4% of repliers has experienced body weight control. A group of 37% in male and 39.6% in female suffered from side effects. 77% of total hoped to be educated about adequate body weight control method. CONCLUSION: Almost of adolescents dissatisfied with their body figure, Many adolescent who is not obese attempt weight loss, and are sufferd from side effects. Therefore, it is required for effective education about body weight control and social attitude permitting adequate body image.
