During the period from May to October 1969, the authors carried out a series of tests with the aim to ascertain the present status of susceptibility of adult cockraoches to various insecticides. The tests on the susceptibility of cockroaches to dieldrin, D.D.V.P., Diazinon; Dibrom, Malathion and lindane were performed with the topical application and the residual film methods under the conditions of 26 degrees C and 80% of relative humidity. The insects tested were collected from Seoul City and were reared at the laboratory. Some of the important results so far obtained can be summarized as follows: The median lethal doses (LD(50)) of the five insecticides against female adult cockroaches were: 0.4 ug/roach or 4.02 ug/body weight (gm) by Dieldrin, 0.29/roach or 2.88 ug/body weight (gm) by D.D.V.P., 0.29 ug/roach or 2.96 ug/body weight (gm) by Diazinon, 0.54 ug/roach or 5.37 ug/body weight (gm) by Dibrom, and 2.96 ug/roach or 29.60 ug/body weight (gm) by Malathion. And those against male adult cockroaches were: 0.18 ug/roach or 3.29 ug/body weight (gm) by Dieldrin, 0.27 ug/roach or 4.89 ug/body weight (gm) by D.D.V.P., 0.16 ug/roach or 2.91 ug/body weight (gm) by Diazinon, 0.49 ug/roach or 8.97 ug/body weight (gm) by Dibrom, and 1.32 ug/roach or 24.19 ug/body weight (gm) by Malathion. The level of susceptibility of adult cockroaches to the insecticides tested was 1.0-1.6 times higher as compared with the results obtained on the Japanese Takashi strain. The median knockdown times (LT(50)) of the female adult cockroaches by insectcides at 1% concentration of 3 mg per square centimetre were 1.82 hours by Malathion, 1.36 hours by Diazinon, 0.56 hours by Lindane, 0.50 hours by Dibrom, and 2.56 hours by D.D.V.P. A marked difference was seen to exist between the males and the females. The female cockroaches were more resistant than the male to Dieldrin, Diazinon and Malathion.

BACKGROUND: Accessory tragi contain a central core of cartilage, which is the most important pathological factor, but often are misdiagnosed as soft fibroma/hair follicle nevi if sections cannot show a central core of cartilage. OBJECTIVES: The purposes of this study were aimed at comparing transverse sections with vertical sections and demonstrating the value of transverse sections about histological diagnosis for accessory tragus. METHODS: We studied 14 cases of patients with accessory tragi. All cases were totally excised and all 16 biopsy specimens (bilateral in 2 cases) were obtained. We classified these biopsy specimens into two groups regarding the removal of cartilage.All specimens were vertical or transverse seiral sectioned and we compared these histologic findings with established histologic diagnostic criteria which Satoh et al. reported. RESULTS: On the specimens of group 1 in which there was cartilage, subcutaneous prominent connective tissue framework whirling around cartilage could be observed on all transverse sections, but was not always present on vertical sections. Prominent connective tissue framework and pilosebaceous units with circular arrangement of eccrine glands were simultaneously in the center of transverse sections regardless of the presence of cartilage. CONCLUSIONS: In this study, transverse sections showed all diagnostic histologic important features for accessory tragus: presence of central cartilage, prominent subcutaneous connective tissue framework, and various degree of pilosebaceous unit, especially with circular arrangement of eccrine glands. So transverse sectioning could be a useful method for accurate histological diagnosis of accessory tragi regardless of the removal of cartilage when doing excisional biopsy.

Cardiac rupture following blunt thoracic trauma is rarely encountered, since it commonly causes death at the scene. With advances in critical care, blunt cardiac rupture has been successfully treated with well-organized team approach including an emergency physician, anesthesiologist, and cardiac surgeon. We encountered a patient with blunt cardiac rupture of the junction of the superior vena cava and right atrium that extended 7 cm to the right ventricular junction. The patient was successfully resuscitated after a closed thoracostomy and pericardiocentesis with fluid loading. Cardiac injury was repaired via mid-sternotomy without cardiopulmonary bypass. The patient recovered without complications and was discharged on the 7th day after surgery.

We performed ERCP manometry of Sphincter of Oddi(SO) before and after endoscopic sphincterotomy(EST) for evaluation of the effect af EST on the SO. The subjects were postcholecystectomized common bile duct stone patients(n=l2) and EST was performed by major incision. The pressure gradient between common bile duct and duodenum before EST (8.6 + 3.9 mmHg) decreased significantly after EST(2.4 +1.7 mmHg). The length of SO before EST(8.8 + 0.8mmHg) decreased significantly after EST(2.5 + 0.8mm). But in each patient, the pressure gradient between common bile duct and duodenum remained in spite of the major incision. In conclusion, EST alters the function of the sphincter of the Oddi, but does not destroy its all protective function. The positive pressure in the bile duct is preserved in contrast to the absolute loss of pressure following surgical transduodenal sphincteroplasty.

From July 1989 to August 1991, we performed 146 cases of endoscopic sphincterotomy(EST). In our series, 9 early complications occurred in 146 cases(morbidity rate: 6.2%), and no fatalities were recognized(mortality rate:0). Four cases with late complications consisted of 2 cases of acute cholecystitis, one case of chalaagitis and restenosis. There were 36 with the gallbladder with stone(11 cases) or without stone(25 cases). Two cases with chalecystitis after EST occurred in the patients with gallbladder stones. EST gives the sufficient result in diagnosis and treatment for various disease of biliary tract. Furthermore, EST was found to be a safe procedure from low rates of complications and fatalities.

Expandable metallic stents(EMS) were implanted in 7 patients with malignant (4 cholangio- carcinnoma, 1 pancreatic cancer, 1 ampullary carcinoma and 1 lymph node metastasis) biliary stricutres and 17 patients with benign(13 intrahepatic strictures of primary intrahepatic stone patients, 2 postoperative stricutres, 1 ampullary stenosis followed by endoscopic sphineterotomy and 1 bilioenteric anastomosis) biliary stricutures. In the fifteen patients out of 17 patients with benign biliary stricture, relief of cholangitis, improvement of liver function or loss of pruritus was observed. But in the 2 patients with.biliary cirrhosis, no clinical improvement was noted. In the malignant strictures with cholangio-carcinoma, the occlusion of EMS occurred in 3 patients and the duration of stent patency was average 2 months in those patients.

Multiple dermatofibromas are rare and some case reports show this disease has been related to generalized defective immune function: autoimmune disease and altered immunity, such as AIDS and systemic lupus erythematosus(SLE), can be treated with immunosuppressive agents. But there are no specific reports of this disease developing in healthy people. We describe a case of multiple dermatofibromas in a 38-year-old healthy man who showed no abnormality of the immune function.
