It is widely blieved that the new bone formation is provoked by fine electrical stress to bone. There have been maay experimental studies that showed much efforts to define these small amounts of electricity, and these fine electricities are being used in the orthopedic field for the treatment of various fractures, nonunions and pseudsrthrosia The auther has checked the electrical potentials changing in the course of fractvre hesling in rabbits femur. Comparing these data with that of the normal control group, the following results were obtained. 1. In the normal rabbit's femur the electrical potentisl was 13.6mV less on the concave side than on the convex side. This finding can be explained by the existence of stress generated potential or piexoelectricity. 2. Electrcal potentials on the fractured femoral sites were lowered significantly from that of the control group. So auther could confirm the existence of bioelectrical generated by increased electrical activity of the living bone. 3. The electrical potential of the fractured femoral site has been decreased 50% and 20% as low as that of the normal site at 8 weeks respectively. It is expected that these lowered electrical potentials may become dose to the normal values when the changed metabolic process due to the fractured bone is no longer functioning and it is believed to take human 2 years to get the normal value.

Morphological changes of the kidney after ESWL in 130 patients are analyzed with CT at Dept. of Urology, Chung-Ang University Hospital from March 1987 to May 1987. Of 130 patients, 9 patients(6.9%) showed renal hematoma. Among 9 patients, 5 patients (3.8%) had subcapsular hematoma and 4 patients(3.1%) had parenchymal hematoma. We analyzed these 9 patients radiologically and clinically. These hematoma were clinically insignificant and self-limited in all cases. So ESWL can be regarded as a safe modality for treatment of the renal and ureteral calculi.

Most osteosarcomas arise spontaneously, but rarely they may be secondary to other benign osseous conditions and may occur following irradiation. Postradiation sarcoma of bone is approximately 5.5 percent of all osteogenic sarcoma. Diagnosis is possible when a sarcoma arising after long latent period(more than 3 years) in irradiated bone and the bone is normal or benign osseous lesion at the time of irradiation. The spontaneously arising osteogenic sarcomas are distribute mainly in the knee region, but postradiation sarcoma arise in any bones, such as long bone of the extremity, pelvic bone, vertebra, craniofacial bone and shoulder girdle bone. Recently we experienced a case of postradiation osteosarcoma of the pelvic bone who received radiation therapy for carcinoma of the uterine cervix 20 years ago.

OBJECTIVES: This study was done to evaluate present status of child and adolescent psychiatric practice in the view of medical consumers. Help seeking behaviour process after recognizing their children's problem, satisfaction with psychiatric service, and difficult problems during practice were evaluated, and variable factors affecting them were analysed. METHODS: Through 10 multi-center point epidemiologic survey, 540 parents and their psychiatrists were involved in this study by structured questionnaire. RESULTS: Above 70% of subjects reported positive response to psychiatric service. The barrier to psychiatric service were different by subjects' age. In children, parents' inability to identify severity of children's problem and proper management place were major reason. However in adolescent, children's lack of desire to receive help and parents' worry about stigma related to receiving help were major barrier to psychiatric service. CONCLUSION: These findings suggest the importance of interagency collaboration and education services. Researchers and policymakers should consider strategies to reduce barrier related to perceptions of mental health problems and services, especially in adolescents.

Hydrops fetalis is diagnosed when abnormal fluid collections are manifest in two or more fetal compartments, including abdominal ascites, pleural effusions, pericardial effusions, skin edema, polyhydroamniosis and placental edema. Although fetal hydrops was hystorically most commonly associated with Rh blood group isoimmunization, the availability of Rh immunoglobulin has increased the proportion of fetuses affected due to nonimmune etiologies. We have experienced a case of nonimmune hydrops fetalis at 32 weeks of gestation in a 27-year-old woman and reported that with brief review of related literatures.

Unlike the small cell carcinoma of the lung, much remains to be discovered about the natural history and of optimal therapy of primary small cell carcinoma of the pancreas. We experienced a case of a primary small cell carcinoma of pancreas with both adrenal metastasis. The patient was a seventy-year old woman who had complained of right upper quadrant abdominal pain for 1 month. Chest x-ray revealed no abnormality. Abdominal CT scan showed a non-enhancing low density mass in uncinate process of pancreas, retropancreatic lymphadenopathy and well defined masses in both adrenal gland. CT-guided biopsy of pancreas showed small cell carcinoma. Herein, we report a case of primary small cell carcinoma of the pancreas with both adrenal metastasis and review the literature.

The pathogenesis of thrombocytopenia in the gestational thrombocytopenia is not understood.This syndrome may represent either the de novo development of ITP or an accelerationof the physiologic pattern of increased platelet destruction that occurs during gestation. Thisdisorder is not easily distinguishable from classical ITP. However, the recognition and diagnosisof this syndrome is important because infants born to individuals with gestational thrombocytopeniaappear to have a markedly reduced risk of developing thrombocytopenia when comparedto infants born to patients with a history of ITP antedating pregnancy. We represent a caseof delivery in severe gestational thrombocytopenia with brief review of the literature.

Isoconazole nitrate is one of the broad-spectrum antimycotic agents recently developed from imidazole derivatives. Authors performed ulticenter trials to evaluate the therapeutic effect of Travogen and Travocort in superficial fungal diseases. In the usual superficial fungal diseases, Travogen was applied 4 weeks. In the inflammatory and eczematoid superficial fungal diseases, Travocort was applied 2 weeks initially and then followed by 2 weeks application of Travogen. One hundred and ninty one patients with superficial fungal diseases were included in this study during g months from December, 1982 to August, 19$3 The obtained results were as follows; The overall cure rate of Travogen and Travocort in each superficial fungal diseases were gl 7g (tinea pedis), 98.

BACKROUND: Polymorphism of glycoprotein IIIa on human platelets is one of the factors in alloimmunization that causes neonatal alloimmune thrombocytopenia (NATP), and the granulocyte antigens NA1 and NA2 are often targets of granulocytes antibodies causing neonatal alloimmune neutropenia (NANP). Currently, serotyping relies on the properties of the typing sera or antibodies and technique used. Genotyping circumvents the problems associated with serotyping. METHODS: The genomic DNA of 200 unrelated pregnant women admitted to Taegu Fatima Hospital was typed for three platelet glycoprotein IIIa-specific antigens (HPA-1, HPA-4, and HPA-6w) and granulocyte antigens (NA1 and NA2). Allele specific amplification test using primer designed to study HPA-1 and HPA-4, restriction fragment length polymorphism to study HPA-6w, and sequence specific primers for NA1 and NA2 were used for genotyping. RESULTS: The genotype frequencies were HPA-1(a+b-) 100%, HPA-4 (a+b-) 97.5%, HPA-4(a+b+) 2.5%, HPA-6w(a+b-) 97%, and HPA-6w(a+b+) 3%. These frequencies are similar to Japanese but different from Caucasian. The gene frequencies of NA1 and NA2 were 0.56 and 0.44 respectively. There are no cases of alloimmune thrombocytopenia and neutropenia in newborns from the 200 studied women. CONCLUSIONS: The differences in genotype frequencies among platelet glycoprotein IIIa-specific antigens and in the gene frequencies of NA in Koreans are shown as compared with other ethnic groups. Therefore it is needed to find the proper screening target antigens and antibodies for Korean NATP and NANP patients.
