In the summer of 1969 from July through October, authors carried out a study of susceptibility in adult female bed bug(Cimex lectularius) in order to ascertain any development of resistance to insecticides in Korea. The test to DDT and Dieldrin was performed in laboratory by the continuous exposure of residues method, with standard impregnated paper used for adult mosqitoes. Some results so far obtained can be summarised as follows: LC(50) were 2.839% in DDT and 0.167% in Dieldrin. The resistance has been arisen 2.4-2.9 times in DDT and 1.6-2.4 times in Dieldrin as compared with London laboratory strain, but they were susceptible 1.4 times in DDT and 180 times in Dieldrin as compared to Israel resistance strain.

8.Surgery for a Complex Anal Fistula.
Journal of the Korean Society of Coloproctology 2008;24(2):77-82
PURPOSE: Because of the complexity and un-expectation of the courses and clinical features for the complex anal fistula, the management of it presents a difficult surgical challenge. Various techniques have been used, such as seton placement, advancement flap closure, muscle filling procedure, and fibrin glue injection. The classic lay-open and seton placement may distort the anal anatomy and result in poor functional outcomes, such as incontinence. Also, advancement flap techniques are associated with relatively high recurrence rates. This study assesses the results of surgery for a complex anal fistula, as performed in Hangun Hospital, Busan. Operative procedures were comprised of two or more separate procedures, including 1) a total fistulectomy, 2) muscle reconstruction, sometimes muscle transposition, 3) direct closure of the primary opening without making a mucosal advancement flap, and 4) a drainage procedure and/or other minor procedure. METHODS: Surgical procedures were performed on 22 patients (18 males) with a complex anal fistula between July 2004 and December 2004. The clinical and the manometric results were analyzed with respect to postoperative recurrence, delayed wound healing, and postoperative fecal incontinence. RESULTS: Nineteen of the 22 patients were completely healed without any sequelae. Treatment failure was encountered in one patient two months postoperatively, when an additional fistulotomy was performed to achieve a cure. There were two patients displaying delayed healing, who were successfully treated by curettage. No patient complained of postoperative fecal incontinence in either the clinical examination on the manometric study (mean resting pressure, 75.5+/-3.5 mmHg; maximal squeeze pressure, 175.7+/-10.3 mmHg). CONCLUSIONS: This short- term study suggests that a direct closure of the internal opening after a total fistulectomy can be an alternative surgical option for the treatment of a complex anal fistula.

Total anomalous pulmonary venous return(connection) is a congenital heart disease. Especially, the reports of the patients with double connections of all pulmonary veins were rare. An infant who underwent operation for total anomalous pulmonary venous return had double drainge of all pulmonary veins to both left vertical vein and anomalous descending vein. This second lesion was not diagnosed preoperatively, but in operative field. Operative treatments were performed by ligation of left vertical vein and central pulmonary vein-to-left atrium anastomosis without ligation of the descending anomalous vein. For these less common variants fo total anomalous pulmonary venous return,a more detailed and precise understanding of morphology can facilitate accurate surgical repair. And also, early detection of the disease is an another issue for a good prognosis.

10.Surgical Treatment of Foot Ulcer in Hansen's Disease.

Damages to the sensory, autonomic and motor nerves in leprosy patients are followed by anesthesia, dryness of the skin and muscular paralysis. Most plantar ulcers in leprosy patients are caused by repetitive moderate stress. Minor injuries such as bruising sustained as a result of the misuse of anesthetic limbs may lead to ulceration, scar formation and secondary infection. Cellulitis develops and destroys subcutaneous tissue, resulting in an infection which can reach the bone. As a result of osteomyelitis, bone is absorbed, sequestra are extruded and the architecture of the foot is destructed. The most common sites of the plantar ulceration are over the metatarsal heads, the base of the fifth metatarsal, the base of the proximal phalanx, and the calcaneus. During the past 9 years, we treated 85 patients with ulcers located on the sole and the dorsum of the foot, and lower third of the leg. To prevent osteomyelitis and amputation of the lower leg, we performed various treatment modalities such as free and pedicle flaps, skin grafts, and mechanical stretching devices of the skin (e.g., Sure Closure, Proxiderm, etc), as well as consistent vacuum-assisted closure. We obtained satisfactory results in most cases. We report detailed results and related references.
