Local deposition of antibiotics has become increasing popular in the management of open fractures or osteomyelitis, and several substances have been employed as the vehicle for delivery. Although the elution characteristics of some substances have been documented, a comparative study of the characteristics of the commonly used substances were performed in order to establish the clinical indications for particular vehicles. Carriers were prepared, which were human iliac cancellous bone, bovine cancellous bone matrix(Lubboc?), absorbable gelatin sponge(Gelfoam?), fibrin glue(Beriplast? P) and polymethylmethacrylate(CMW?) for elution characteristics of vancomycin. The each carriers were immersed on the 20 ml of PBS and then obtained the samples for analysis of concentration of vancomycin at first, second, third, fourth, fifth, sixth, fourteenth, twenty-first, twenty-eighth day after immersion. The assay technique was fluorescent polarization immunoassay(Abbott, Dallas, Texas, U.S.A.). Nearly 50% of vancomycin was released from human iliac cancellous bone, Lubboc? and fibrin glue during the first 3 days, and negligible after first week. Gelatin sponge produced high local concentration of vancomycin during the first week. PMMA eluted the only 6% of vancomycin during the first day and trace amount detected as long as 4 weeks. There are significant statistical difference among carriers at second and fourth week(ANOVA test, P < 0.05). The authors considered that human iliac cancellous bone, Lubboc? ,Gelfoam? and fibrin glue may be best employed when brief antibiotic coverage is required, whereas PMMA may be better suited for long-term coverage.

Nine scaphoid non-unions, which were treated by through curettage of the scar tissue on pseudarthrosis, iliac bone grafts between the fragments and Herbert screws fixation, were analysed. The average follow up period from operation was 16.9 months. The interval between the fracture and the time of the operation ranged from 10 months to 48 months(average 21.6 months). Average union time was 14 weeks after operation. The initial radiologic cystic changes disappeared and overall clinical results were improved. Mean postoperative range of motion of the wrist was flexion 55 and extension 45°. Three of them had DISI deformity preoperatively which their scapholunate angles (mean 104°) has been corrected after reduction (mean 75°). In one case among three DISI deformities, partial radial styloidectomy and triscaphe fusion were added (to bone graft and Herbert screw fixation). A case of incorrect positioning of the screw and a case of neuroma were complicated. Treatment of scaphoid nonunion with curettage of the scar tissue and iliac bone graft and Herbert screw fixation seems to be encouraging to regain the normal anatomy of scaphoid and function of the wrist.

A perplexing developmental error is 46,XX congenital absence of vagina ( Mayer-Rokitan-sky-Kster-Hauser syndrome, Mullerian dysgenesis, vaginal aplasia ). The Mayer-Rokitansky-Kster-Hauser syndrome refers to the climical entity consisting of primary amenorrhea associated with congenital absence of the vagina, 46,XX karyototype, a rudimentary uterus or complete absense, normal overian function and normal ovulation, normal female breast development, body proprotion and body hair, frequent association of renal, skeletal and other cpngenital anomalies. This syndrome results from agenesis of both Mllerian ducts or from a failure of the Mllerian ducts to estavlish a proper communication with that part of the vagina from the urogenital sinus. A case of mayer-Rokitansky-Kster-Hauser syndrom was reviewed briefly.

The Congenital Ulnar Drift of the fingers is a relatively uncommon and has symmetrical malformations of hand, face and foot characterized by MP joint flexion contracture and ulnarward deviation of the fingers and microstomia, In tarsal deformity, there are clubfoot and congenital vertical talus with rocker bottom deformity. In treatment, the report of the surgical treatment was rare. We experienced congenital ulnar drift of fingers in 2 patients in one family, which were treated by dome resection corrective osteotomy of the metacarpals. Therefore remarkable symptomatic improvement was obtained.

Since the pattern of the frequency distribution of a parasite within a host showed an overdispersed pattern, various statistical models such as Poisson, negative binomial and lognormal distributions have been applied on the population dynamics in host-parasite relations. The observed data on the number of metacercariae of Clonorchis sinensis in a suitable intermediate host, Pseudorasbora parva which were collected from an endemic area, Juk-Rim River, Kim-Hae Goon, South Kyong-Sang Do were applied on the statistical models. The results obtained are as follows: By the calculation of the raw data, 258(94.9 percent) out of 272 fish showed positive to the metacercarial infection of C. sinensis. The mean number of metacercaria in a fish was 335.1. The standard deviation was 250.6 and the mode was observed between 250 and 299. The frequency distribution pattern of metacercariae of C. sinensis within the fish host in surveyed area was fitted to the lognormal distribution (0.05

To understand the mode of transmission in clonorchiasis, a survey was made in Kim-hae Goon, South Kyong-sang Do (=Province). The mathematical analysis of the age prevalence was done on the egg positive rates. And another analysis for the comparison was also made to the cited data from two areas, North Kyong-sang Do and Ko-yang Goon, Kyong-gi Do. Some catalytic models of H. Muench (1959) were applied to the observed age prevalence. Because the both parameters, such as force of infection(a) and loss of positivity(b) were considered to be constant for a long period in the surveyed area, the two stage catalytic model by Muench was chosen to the analysis. In the surveyed area, Kim-hae Goon where the egg positive rates were 56.2 percent and 61.2 percent (by Kim, 1974), the constant values of 'a' were found to be 0.051 and 0.089 respectively. In other words, the force of infection was 51, 89 per 1,000 susceptibles. The values of 'b' were found to be 0.006 and 0.005. This means that the rates of disappearance from egg positive cases to negative were 6 and 5 per annum per l,000 positive cases in above area. Therefore, the two catalytic curves were expressed by the following equations, y = 1.133 {e(-0.006t) - e(-0.051t)} and y = 1.047 {e(-0.005t) - e(-0.089t)} respectively. In the cases of North Kyong-sang Do and Ko-yang Goon, Kyong-gi Do where the egg positive rates of clonorchis shown as 27.7 percent and 15.2 percent by Shin (1964) and Kim (l974), the curves were expressed by y = 1.769 {e(-0.010t) - e(-0.034t)} and y = 2.857 {e(-0.020t) - e(-0.027t)} respectively. From the above mathematical analyses by age prevalence in clonorchiasis, it was considered that the mode of transmission of clonorchiasis in the surveyed area, Kim-hae Goon presented more rapid pattern than those of North Kyong-sang Do and Ko-yang Goon, Kyong-gi Do.

Breast carcinoma has been infrequently reported in children. About 25 cases have been reported in world literatures since first description in 1913, by Bryan. We present a case of juvenile breast carcinoma in a 17 months old girl with brief review of literatures. Grossly, the submitted specimen is grayish white and measured by 1.3x1.0x0.8 cm in size. It is not encapsulated and its cut surfaces are homogeneous. Microscopic examination showed a neoplastic proliferation of duct cells forming mainly glandular spaces with focal papillary pattern, solid sheets or cribriform pattern. The glandular spaces were filled with collections of PAS-positive eosinophilic secretory materials. The individual cell varied from columnar to polygonal and showed moderate hyperchromatism and variation of nuclear size. Mitoses and necrosis are not found. Tumor cell invasion into the stroma was found.

Using atomic absorption spectrometry Pb, Cd, Cu, Zn and Fe were measured in sweat and Pb, Cd, Cu and Zn, in blood. The subjects were 22 healthy males, aged between 23-44. Sweating was induced with an environmental room (1 hour at 46C dry bulb and 36C wet bulb). Sweat samples were obtained from the left arm by the armbag technique. The sweat volume was 23.3+7.3ml(n= 22). The concentrations, in ug/ml, of trace elements in sweat were : lead, 0.18+0.17(n=22); cadmium, 0.006+0.006(n=22); copper, 0.37+0.66(n=10); zinc, 0.63+0.5(n=10); and iron, 0.22+0.12(n=10). The concentrations, in ug/ml, of trace elements in blood were : lead, 0.28+0.15(n=20); cadmium, 0.005+0.007 (n=20); copper,0.69+0.22(n=20); and zinc,5.61+0.86(n=20). These results clearly showed the significance of sweating as a route of excretion of trace element.
