Three anopheline mosquitoes in Korea were studied for their abilities as vectors for Plasmodium vivax. The female mosquitoes of Anopheles lesteri, An. pullus and An. sinensis were allowed to suck malaria patient blood until fully fed, and they were then bred for 2 weeks to develop from malaria parasites to sporozoites. The result from the above confirmed the sporozoites in one An. lesteri of one individual and five An. sinensis of six individuals. We also reconfirmed that An. sinensis was the main vector to transmit malaria and An. lesteri as well as An. sinensis were able to carry Korean malaria parasites. Therefore, we propose that diversified study is needed to manage malaria projects.

Endoscopic variceal ligation(EVL) is newly developed method to manage esophageal variceal bleeding. This study asse initial control rate of active variceal bleeding, incidence of rebleeding and complications in EVL. From June in l992 to December in 1994, this study was performed on 70 patients who had visited to our medical center for melena or hematemesis by acute esophageal variceal bleeding. In all of 70 cases, eradication of esophageal varix was performed and variceal bleeding was controlled well. And first session was performed successfully with EVL. But rebleeding was occured in 12 cases(11 cases caused by esoyhageal varix and 1 case caused by esophageal ulcer) during follow-up period, so EVL therapy was performed repeatedly and 8 cases were eradicated and 4 cases were uncontrolled and died, and then 94% hemostatic effect was achieved during follow-up period. Complications of EVL therapy were mild(substernal discomfort in 12 cases, substernal pain in 4 cases, fever in 3 cases, mild dysphagia in 2 cases) and well controlled. Superficial esaphageal ulcer was shown in 18 cases by follow-up endoscopy after 1 week. These results show that EVL is a good therapeutic method to control active variceal bleeding and eradication of varix with repeat treatment. In conclusion, EVL is an effective and safe method of treatment and prevention for esophageal variceal bleeding.

In order to study the range of flight and feeding activity of Anopheles sinensis, the dispersal experiment was conducted in Paju city, located in the northern part of Gyeonggi-do, Republic of Korea, during the period of 7th to 28th September 1998. Unfed females An. sinensis were collected in cowshed and released after being marked with fluorescent dye at 23:00 hours on the same day. Released female mosquitoes were recaptured everyday during 21 days using light traps, which were set at 10 sites in the cowsheds located 1, 3, 6, 9 and 12 km north-northwest and north-northeast and at 3 sites located 1, 6 and 9 km toward south-west from the release point. In addition, to study the longest flight distance in one night, we set the light traps at 16 and 20 km toward north-northeast from the release site. All the collected mosquitoes were placed on filter papers and observed on UV transilluminator after treatment with one drop of 100% ethanol. Out of 12,773 females of An. sinensis released, 194 marked females mosquitoes were recaptured, giving 1.52% recapture rate. Of 194, 72 mosquitoes (37.1%) were recaptured in light traps from three places set at 1 km from the release point, 57 mosquitoes (29.4%) from two places at 1-3 km, 41 mosquitoes (21.1%) from three places at 3-6 km, 20 mosquitoes (10.3%) from three places at 6-9 km, and 4 mosquitoes (2.1%) from two places at 9-12 km. Since 170 female mosquitoes (87.6%) out of 194 marked mosquitoes were captured within 6 km from the release point, this flight radius represents the main activity area. An sinensis was found to be able to fly at least 12 km during one night.

The frequency of intestinal tuberculosis is relatively common; however, primary tuberculosis of the appendix remains a rarity. We report on a case of primary tuberculous appendicitis for which we obtained the MDCT images revealing thickening of the appendix and the surrounding lymphadenopathies.

A broad spectrum of colonic complications can occur in patients with colon cancer. Clinically, some of these complications can obscure the presence of underlying malignancies in the colon and these complications may require emergency surgical management. The complications of the colon that can be associated with colon cancer include obstruction, perforation, abscess formation, acute appendicitis, ischemic colitis and intussusception. Although the majority of these complications only rarely occur, familiarity with the various manifestations of colon cancer complications will facilitate making an accurate diagnosis and administering prompt management in these situations. The purpose of this pictorial essay is to review the CT appearance of the colonic complications associated with colon cancer.

PURPOSE: The purpose of this study was to understand the principle of percutaneous nephrolithotomy(PNL), toincrease its success rate, and to base the radiologic approach on preoperative interventional tract dilatation. MATERIALS AND METHODS: Twenty-six patients(male, 19, female, 7) with staghorn or pelviocalyceal calculi who hadundergone PNL were included in this study. After percutaneous nephrostomy(PCN) was performed in each patient, thetract was dilated to 30F with Amplatz dilators using coaxial techniques or a 30F, 10cm high-pressure tractdilatation balloon. One day before the calculi were fragmented and removed by PNL, a 30F Amplatz sheath wasinserted under local anesthesia. The time required for tract dilatation, complications, and surgery was analyzed. RESULTS: Percutaneous tract dilatation were successful in all patients, and forceps, a nephrolithotome and anephroscope were successfully introduced into the pelvocalyceal system. The average procedure time was 19.5minutes ; a double J stent was replaced in the pelvocalyceal system of 13 of 26 patients (50%) ; because ofimproper catheter direction or/and bleeding, the Amplatz sheath was replaced in three. After PNL, complicationsinvolving renal hematoma occurred in one patient. This did not affect the patient's prognosis, however. CONCLUSION:Owing to its short procedure time and low complication rate, interventional preoperative tract dilatation forPNL is thought to be an effective technique for patients with staghorn or pelvocalceal calculi.

PURPOSE: Little data is currently available on the use of the impulse oscillometry system (IOS) parameter in analyzing the lung function of young children with cough-variant asthma (CVA) and classic asthma. The aims of this study were to evaluate the bronchial responsiveness between patients with CVA and those with classic asthma using dose-response slope and various cutoff values. METHODS: A methacholine challenge test and a pulmonary function test were performed in 43 children with classic asthma and 26 children with CVA using IOS, and the respiratory resistance (Rrs) and reactance (Xrs) were obtained. The bronchial responsiveness were assessed by provocative concentration causing an 80% fall from baseline in reactance at 5 Hz (PC80_Xrs5) and a 40% increase in resistance at 5 Hz (PC40_Rrs5) and calculating from the degree of dose-response slope (DRS) for airway resistance and reactance. RESULTS: There was no significant difference in base lung function between the two groups. However, the mean DRS_Xrs5 and the number who showed more than an 80% fall in reactance were significantly higher in classic asthma group than those in CVA group (P=0.040 and P=0.040, respectively). CONCLUSION: The use of DRS in oscillatory reactance at 5 Hz is useful for the differential diagnosis of classic asthma and CVA based on bronchial hyperresponsiveness.

PURPOSE: To provide a case report of 1 patient (1 eye) who experienced recurrences of conjunctival papilloma and was treated with complete resection, electrocauterization, cryotherapy, intraoperative application of mitomycin C and postoperative topical mitomycin C. CASE SUMMARY: We evaluated the clinical course of a 42-year-old male with recurrent conjunctival papillomas on the left upper and lower tarsal conjunctiva who was treated 10 times with a simple resection over the past 8 years. The patient was treated with complete resection, electrocauterization, intraoperative application of mitomycin C and cryotherapy. Topical mitomycin C was applied for 1 month. There was no recurrence or complications for 12 months postoperatively. CONCLUSIONS: Complete resection, electrocauterization, intraoperative application of mitomycin C, cryotherapy and topical mitomycin C in patients with recurrent conjunctival papilloma was shown to be an effective treatment without recurrence and complications.
