Effects of different application of nematicides (fosthiazate 5% G, ethoprophos 5% G, and diazinon 34% EC) for the control of Aphelenchoides fragariae in strawberry were evaluated in a greenhouse experiments. Mother strawberry (Fragaria grandiflora) cv. Yeohong were dipped in solution of nematicides (fosthiazate or ethoprophos at 2.5 g a.i./liter in $20^{\circ}C\;or\;46^{\circ}C$) for 10 min. and planted in a greenhouse for dipping treatment. For the compare, mother strawberry were dipped in hot water for 10 min. without chemicals. For soil treatment, fosthiazate or ethoprophos at 3 kg a.i./ha were mixed into soil. For foliar spray, diazinon at 3.4 g a.i./liter was sprayed at foliage until runoff. At 40, 80, and 100 days after planting, runners were harvested from each treatment and the rate of nematode infestation and the number of nematodes per plant were examined. After 100 days of planting, mother strawberry plants dipped in fosthiazate solution (2.5 g a.i./liter, $20^{\circ}C$) for 10 min. produced more number of healthy runners and reduced % of infected runner as much as 90% and also had fewer nematodes per runner. Fosthiazate was more effective than ethoprophos. Foliar application of diazinon was reduced A. fragariae populations only in early season. Hot water treatment and nematicide soil treatment were less effective. 딸기잎선충의 피해를 방지하기 위하여, 딸기잎선충에 감염된 딸기 모주를 정식 직전에 살선충제에 침지 처리하여 토양에 정식하고 이들로부터 발생되는 자묘의 딸기잎선충 감염 정도를 조사하였다. 처리는 살선충제 ethoprophos 5% 입제와 fosthiazate 5% 입제를 토양(3 Kg a.i./ha), 살선충제-냉탕침법(2.5 g a.i./liter, $20^{\circ}C$), 살선충제-온탕침 법(2.5 g a.i./liter, $46^{\circ}C$)으로 각각 처리하였으며, 그 효과를 무처 리, (무농약)온탕침법 및 diazinon 34% 유제(3.4 g a.i./liter) 엽면처리와 상호 비교하였다. 정식 100일후 조사시, fosthiazate-냉탕액 침지 처리구의 자묘는 무처리에 비하여 감염률은 90% 낮고, 선충밀도는 98% 감소되어 가장 방제효율이 높았다. Fosthlazate-냉탕액 침지 처리구의 자묘의 수와 무게도 무처리에 비하여 거의 2배 많았다. 살선충제 2종중에서는 fosthiazate가 ethoprophos보다 방제 효과가 좋았다. Diazinon 엽면 살포 처리와 기존의 온탕침법은 정식 초기에만 딸기잎선충 밀도 억제 효과를 보였다. 딸기 모주 살선충제 침지법은 방제 효율이 높고, 딸기 생산은 모주에서 발생된 자묘를 이용하여 다음해에 이루어짐으로 농약 잔류의 위험도 없다.

N/A Objectives: This study was undertaken to evaluate the usefulness of EST in patients with common bille duct stones and obstructive jaundice Methods: Since 1975, 5626 cases of endoscopic retrograde cholangiopancreatography(E,R.C.P.) were performed at Kwangju Christian Hospital in Kwangju, Korea. From December, 1981 to June, 1994, 1155cases of endoscopic sphincteropapillotomy (E,S.T.) were perfromed. Results: In 1155cases of E.5.T., we have obtained 849cases of common bile duct stone, other cases of obstructive jaundice due to clonorchiasis, ampulla of Vater cancer, pancreas cancer, comon bile duct cancer, 41cases of stones were removed by Dormia basket and balloon catheter under direct visualization, 278cases were passed in stool, 421cases removed by the confirmation of E,R.C.P. or T-tube cholangiography. In 323cases, stones were not removed but the symptoms and laboratory findings were improved. Complications were happended in 37cases. 27cases of bleeding, 6cases of cholangitis, 2cases of peritonitis, one case of acute pancreatitis, one case of perinephric abscess were happened. 31cases of complication were improved by conservative treatment and operation. In other 6cases, 4cases of bleeding and 2case of cholangitis were expired. In 54cases of 5-year follow up after E.S.T we have obtained 32cases of recurrent common bile duct stones, 17cases of pancreatitis, 3cases of cholangitis. The condition under which E.S.T. become difficulty or did not succeed included periampullary diverticula, fibrotic stenosis of ampulla of Vater and stones in the intrahepatic duct or gall bladder. Conclusion: With improved E.S,T. technical maneuverability, we could diminish the frequency of complication including bleeding, pancreatitis and cholangitis and perform E.S.T. successfully in cases with periampullary diverticula. In cases of stones which did not remove after E.S,T., we think that extracorporeal shockwave lithotripsy, electrohydrauric lithotripsy, mechanical lithntripsy. laser lithotripsy will be proper management.
