The development of aorticpulmonary bodies was studied by electron microscope in human fatuses ranging from 40mm to 260mm crowm-rump length. The aorticpulmonary bodies were observed in the wall of the aorta, and of the pulmonart trunk and arteries. At 40mm fetus, the aorticopulmonary bodies were composed of clusters of primitive glomus cells, primative supporting cells, unmyelinated nerve fibers, and capillaries. The primitive glomus cells possessed large nuclei, dense-cored vesicles, many Golgi complexes, rough endoplasmic reticulum, and, multivesicular bodies, the primitive supporting cells were agranular with attenuated cytoplasmic processed which partially ensheathed the primitive glomus cells. Synaptic contacts between the axon terminals and the aoma of primitive glomus cells were first observed. The primitive glomus cells increased somewhat in size and number by 90mm fetus, but retained essentially the same characteristics as at the earlier stage. Desmosome-like contacts between glomus cells and adjacent cells were commonly seen. At 160mm fetus, the glomus cells had increased accumulations of all organells and numerous dense cored vesicles. The supporting cells completely invested the glomus cells. Two types of nerve terminals were observed. One type contained small agranular vesicles which was identified as cholinergic axon terminal. The other contained a majority of small granular vesicles which was classfied as adrenergic axon terminal. Synaptic contacts between the cholinergic axon terminals and the soma of the glomus cell were observed. During next prenatal stage up to 260mm fetus the glomus cells and the supporting cells resembling those in adult were present. It is concluded that the ultrastructural features of these aorticopulmonary bodies are similar to those of the carotid body. It is therefore suggested that the aorticopulmonary bodies of the human fetures have a chemorecepter function similar to that of the carotid body.

1. Fifty one cases of fractures of the shaft of the femur in children, treated at Seoul National University Hospital during the seven years, from August 1962 to July 1969, were analyzed. 2. In thirty eight of the cases fracture involved the middle third of the shaft, in eleven the upper third, and in two the lower third. 3. Bryant traction was employed in fifteen of the cases ranging from four months to six years of age. One case, five years old, was complicated by Volkmanns ischemic contracture on both legs. 4. Russell traction was employed in eleven of the cases ranging from six to fourteen years of age. Angulation and distraction must be watched especially in the younger age group, although we encountered no serious complications which required subsequent treatment. 5. Hoke traction was employed in twelve of the cases ranging from six to eleven years of age. Although this form of treatment is not particularly popular, we are of the opinion that it is the treatment of choice over two years of age and,under six years of age and that between six and twelve years of age it may be optionally employed along with Russell traction. We found it. particularly useful and convenient in selected cases in which Russell traction could not be effectively employed. 6. In some of the complicated cases, open reduction and internal fixation, closed reduction with pin and plaster immobilization, or skeletal traction was employed.

PURPOSE: Henoch-Schonlein purpura nephritis(HSPN) accompanied by nephrotic syndrome(NS) is known to have a poor prognosis and effective treatment is still controversial, even though both corticosteroids and immunosuppresant have been used for therapy. Cyclosporine A(CsA) is a well known immunosuppresant and widely used in renal transplantation and glomerular diseases especially steroid resistant. The aims of this study was to evaluate the therapeutic effect of CsA and to compare CsA with previously reported our data of rifampin(RFP) and azathioprine(AZA) in children with HSPN accompanied by NS. METHODS: 37 HSPN patients with NS confirmed by renal biopsy were selected. Of these, 17 patients were treated with CsA(5 mg/kg/day) for 6-8 months, 7 children were treated with RFP(10-20 mg/kg/day) for 9-12 months and 13 patients were treated with AZA(2 mg/kg/day) for 8 months. Along with these regimens, low dose oral prednisolone(0.5-1 mg/kg, qod) was also used. Sequential renal biopsy was done in all patients 1 month after termination of treatment. RESULTS: Complete remission rate of nephrotic syndrome was 5S.8% in CsA, 57.1% in RFP and 38.4% in AZA group after 17, 22, 11 months of mean follow-up period. Overall remission rate including partial remission was 88.2% in CsA, 85.7% in RFP and 84.6% in AZA group. Disappearance rate of hematuria was 58.8% in CsA, 57.1% in RFP and 46.2% in AZA group. Improvement of grade of clinical status was observed in 17 out of 17 CsA, 7 out of 7 RFP and 10 out of 13 AZA group. Improvement of pathologic class on sequencial renal biopsy was shown in 5 CsA(29.4%), none RFP(0%) and 2 AZA group(12.4%). Improvement on histologic immune-deposition was seen in 15 CsA(88.2%), 6 RFP(85.9%) and 4 AZA group(30.8%). CONCLUSION: In conclusion, Both CsA and RFP treated groups showed better result in complete remission rate of nephrotic syndrome and significant inprovement of histologic immune-deposition compared with AZA treated group(p=0.004). So, we recommend CsA and RFP rather than AZA for immunosuppresant treatment in HSPN with nephrotic syndrome.

PURPOSE: To determine the plain film findings of acute neuropathic joint in diabetic foot. MATERIALS AND METHODS: Acute neuropathic joint in diabetic foot was considered when fragmentation of the articular ends of bone and subluxation of the affected joint developed within eight weeks after clinical onset of diabetic gangrene. Eight toes of six diabetics were satisfactory to our criteria. We analyzed plain radiographic findings of the affected joint and soft tissue, interval changes in follow-up radiographs, and deformities after healing. RESULTS: The time interval between clinical onset of gangrene and bone destruction ranged from 2 weeks to 4 weeks(mean 2.6 weeks). Plain radiographs showed fragmentation of the articular ends, subluxation, and soft tissue swelling of the metatarsophalangeal joint or interphalangeal joint. The significant feature of these patients was rapid progression of the lesions. Clinically, all patients had diabetic gangrene in affected toes, however, there was no evidence of osteomyelitis in our series. Amputation was done in 2 cases, and lesions in 3 of the remaining 4 cases were repaired spontaneously with regression of gangrene, leaving radiological residua such as pointed-end, tapered-end, and ball and socket deformity. CONCLUSION: Rapid disorganization of the joint with associated evidence of soft tissue gangrene in plain radiograph is believed to be valuable for the diagnosis of diabetic osteoarthropathy.

PURPOSE: This study was done to identify effects of cognitive function and cancer coping on quality of life among women with breast cancer treated with antineoplastic agents. METHODS: The study was correlational research and participants were 145 women with breast cancer who had received antineoplastic agents. Data were collected from October to November, 2015 via online replies. Cognitive function was measured with the Functional Assessment of Cancer Therapy-Cognitive Function Version-3 (FACT-Cog), cancer coping, with the Korean Cancer Coping Questionnaire (K-CCQ), and quality of life with the Functional Assessment of Cancer Therapy-Breast Version-4 (FACT-B). Data were analyzed using descriptive statistics, t-test, ANOVA, Scheffé test, ANCOVA, Bonferroni test, partial correlation coefficient, and hierarchical multiple regression with SPSS 21. RESULTS: Cognitive functions, total individual coping, and interpersonal coping explained 42% of quality of life. Cognitive function (β=.35, p<.001) was the best predictor of quality of life, followed by total individual coping (β=.34, p<.001), and interpersonal coping (β=.26, p<.001). CONCLUSION: Results indicate that cognitive function and cancer coping are meaningful factors for quality of life among breast cancer survivors. Therefore when developing intervention programs for these women, content on cognitive function and coping skills as well as coping resources should be included.

There are substantial evidences indiacting that anesthesia and surgery produce significant suppression of immune function. It is generally recognized that immunosuppressive manifestations such as lymphopenia, granulocytosis, decreased transformation to various antigens and impaired neutrophil chemotaxis could be followed by surgical operation. anesthetic agents may also have both direct and hormone-mediated indirect effects on immune systems. Recent evidences indicate that immunosurveillance mechanisms are not only important in the management of emerging infection and malignancy, but also critical to successful elimination of microscopic residual tumor after operation. This study was done to investigate the effeets of halothane anesthesia on T-lymphocyte subpopulations in patients undergoing hysterectomy. Lymphocyte, granulocytes and T-lymphoeyte subpopulations were counted before, during and after anestesia. The results showed that the decrease in the CD4+ cells (helper/inducer T-cells) was bigger than the decrease in the CD8+ cells (suppressor/ cytotoxic T-cells). CD3+ cells (total T-cells) and CD45R+ cells were also decreased. However, these decrease turned to normal values in 5 days. The overall result of this study suggest that anesthesia with halothane may bring temporal suppressive effect on the immunologic responses.
