In order to find out a valuable control measure for soil-transmitted parasties, the infectivity in mice of Ascaris eggs irradiated with Cobalt(60) were examined. The results were summarised as follows. In vitro, Ascaris eggs irradiated with larger doses of Cobalt(60) developed poorly, and no difference was found between fresh eggs and those cultured for a few days. Ascaris eggs irradiated with doses of 200,000 rad. developed at the rate of 90 percent after 4 weeks, whereas those irradiated with 1,000,000 rad. developed 28 percent. Ascaris eggs irradiated with Cobalt(60) after 2 weeks of culture were poor in development compared with those of 4 week culture. Eggs cultured for 5 weeks showed weaker infectivity in mice than those cultured for 8 weeks. In the control groups, the infectivity in mice of Ascaris eggs was remained the same between 5 and 8 weeks. The minimum dose of Cobalt(60) irradiation effective for preventing infectivity in mice was estimated to be 200,000 rad.

Primary tumors of the adrenal cortex are comparatively rare. In the medical literature they are most frequently reported as single case. Because of their infrequent occurence some features of their clinical behavior and pathologic anatomy are not widely known. For this reason the recording of the 7 cases from the Department of Pathology, School of Medicine, Chungnam National University is thought to be worth while. Of the seven tumors, five were associated with primary aldosteronism, one Cushing's syndrome, and the remaing one virilizing syndrome. All were benign. Females were affected more frequently than males. Adrenocortical adenomas tend to be small, weighing less than 42 gm. The tumors associated with primary aldosteronism were composed of zona fasciculata-like cells and "hybrid" cells. The tumor with Cushing's syndrome consisted of zona reticularis-like cells. The tumor with virilizing syndrome consisted of zone reticularis-like cells.

Luque introduced new posterior spinal instrumentation by segmental sublaminar wiring for spinal deformity in 1976. This system initially developed for the treatment of paralytic scoliosis, but now its application was extended to treatment of other types of scolisis, spinal fractures and spondylolysthesis. Advantages of this system in scoliosis are better correction force and secure internal fixation enabling early ambulation without external support. Disadvantages include longer operation time, possibilities of epidural bleeding and dural laceration. Luque instrumentation in thoracic and lumbar spine fracture is an effective means of obtaining following goals: provide reduction, maintenance of alignment, restoration of stability, prevention of deformity, low pseudarthrosis rate and early mobilization without external support. Luque instrumentation were carried out in 5 cases at Dept. of O.S. at SNUH from Oct. 1983 to Feb. 1984 with excellent results. The average follow-up period was 7.4 months and there was no complication. Two cases of unstable thoracic and lumbar spine fractures were treated with Luque instrumentation with fusion. The use of double sublaminar wiring with Luque rods, two levels above and two levels below on area of fracture provided early stabilization to allow rehabilitation without external immobilization. Three cases of paralytic scoliosis underwent Luque instrumentation by a modification of the Galveston technique with fusion. Average preoperative curve was 110°(ranged from 101° to 126°). Immediate postoperative correction was 58.7°(46.6%) and average 7 months-following result was 56.3°(48.3%). Operation time averaged 6hr 7min and blood loss was averaged 12 pints. Those patients required instrumentation from the pelvis to middorsal segment, in an effort to control the curve and associated pelvic tilting. In early follow-up the author obtained remarkable correction in paralytic curves, and the pelvic obliquity were well corrected with a pelvis and provid ing with better sitting balance.

In 5 cases of congenital coxa vara, 7 cases of acquired coxa vara and 4 hips in 3 cases of acquired coxa valga, we performed subtrochanteric osteotomies at Department of Orthopedic Surgery, SeoulNational University Hospital, from December 1980 to February 1984. At a relatively short interim follow-up, following observations were made on the correction of the femoral neck-shaft angle deformities. l. In the congenital coxa vara group, at an average follow-up of 1 year and 3 months, 97.9% of the correction obtained by osteotomy was maintained, based on the roentgenographic measurements of femoral neck-shaft angle. In the acquired coxa vara group, at an average follow-up of 1 year and 2 months, 93.3 % of the correction obtained by osteotomy was maintained. In the acquired coxa valga group, at an average follow-up of 1 year and 5 months, 92.9% of the correction obtained by osteotomy was maintained. 2. At final follow-up, leg length gain averaged 1.26cm in the congenital coxa vara group and 2.23cm in the acquired coxa vara group. An average 0.70cm decrease in leg length was noted in the acquired coxa valga group. 3. Trendelenburg sign, which was positive in all the cases of the congenital and acquired coxa vara group, reverted to negative in all. 4. Slight overcorrection in cases of the acquired coxa vara and undercorrection in cases of the acquired coxa valga, is recommended for later loss of surgically corrected femoral neck-shaft angle. In the congenital coxa vara, it appeared that loss of correction was relatively minor.

In 1973, Steel described triple innominate osteotomy in which the ischium, the superior pubic ramus and ilium superior to the acetabulum are divided and the acetabulum is repositioned anterolaterally and is stabilized by a bone graft and metal pins. Its goal is to establish a stable hip for dislocation or subluxation of the hips in older children and adults on whom it is impossible to correct effectively the instability by any one of the more conventional osteotomies, i.e. Salter's, Pemberton's or Chiari's, or by the capsular arthroplasty of Colonna. During the eleven years and eight months, from December 1973 to August 1985, at the Department of Orthopedic Surgery, Seoul National University Hospital, we performed Steel's triple innominate osteotomy on 41 cases, of which 37 were residual poliomyelitis and 4 septic hip residua. 4 cases of residual poliomyelitis were lost during follow up. The remaining 37 cases were reviewed for the efficacy and limitations of triple innominate osteotomy. We observed following conclusions: 1. Aside from congenital dislocation and dysplasia of the hip, paralytic conditions, such as residual poliomyelitis, are good indications of Steel's triple innominate osteotomy in older children, adolescents and young adults. Acetabular acclivity is adequately reduced and stability is improved. 2. Septic hip residua, including healed tuberculosis, is another indication of triple innominate osteotomy, particularly when total hip arthroplasty is contemplated. 3. When abductors are partially paralyzed, triple innominate osteotomy alone results in appreciable increase in abductor power, by providing a better muscle tension. 4. Substantial gain in leg length is an added advantage of triple innominate osteotomy. An average of 1.74 cm was gained at osteotomy site in our series. In adults, when limb shortening is relatively m i nor, triple innominate osteotomy alone can be a more convenient alternative to conventional, more formidable method of leg length equalization, such as femoral lengthening. This is particularly true when there is some instability or when abductors are weak. 5. Following improvement in mechanical stability by triple innominate osteotomy, weak abductors and extensors may be augmented by appropriate muscle transfer, resulting in more stable hip functionally. 6. In a hypermobile paralytic hip, iliopsoas tenotomy is neither necessary nor desirable at the time of osteotomy. When the hip is dislocated, or when the hip has marked flexion deformity, iliopsoas tenotomy fascillitates adequate correction, but this greatly increases the risk of neurological complication.

Usually egg count technique has been employed to know the intensity of infestation of human intestinal helminths and to elucidate the effects of anthelmintics. Comparing the three egg count methods - Stoll's egg dilution method, Beaver's direct smear method and FHK counting board method - the authors reached the following results: As the result of application of the three methods to 75 Ascaris egg positives and 95 Trichocephalus egg positives, in the case of Ascaris eggs, the egg detection rate was 99 per cent by Stoll's method, 97 per cent by Beaver's method and was lowest by FHK method at 79 percent. Meanwhile, in Trichocephalus eggs, Stoll's method revealed 92 percent, Beaver's method 95 percent, and FHK method 95 percent, there being no noticeable differences. With regard to EPG, in counting Ascaris eggs, Stoll's method showed a value closest to the actual number of eggs, and the value revealed by FHK method was smaller than the actual number. As the result of comparing the coefficiencies of variation of the three egg counting methods, both in Ascaris eggs and Trichocephalus eggs, the FHK method showed the smallest, followed by Stoll's method and Beaver's method.
