The influences of adrenal corticosteroid on the development and regression of neurons of dentate and hippocampus were studied by adrenalectomy and steroid overload in neonatal rats. The results obtained were as follows. 1. The cell death occurred naturally in numerous dentate granule cells and hippocampal pyramidal cells. 2. The number of dentate granule cells undergoing cell death decreased by injection of adrenal corticosteroid, but increased in adrenalectomized rat brains. The changes occurred prominently at postnatal day 6. 3. The number of hippocampal pyramidal cells undergoing cell death decreased in CA3 region by injection of adrenal corticosteroid, but was not changed in adrenalectomized rat brains. However, other regions exhibited no change by adrenal corticosteroid and adrenalectomy. 4. The cell death of pyramidal cells of CA3 region occurred in close relationship with the cell death of dentate granule cells, which was different from other CA regions. In summary, the cell death of dentate and hippocampal neurons occurred naturally but seemed to be influenced by other factors as well as adrenal corticosteroid.

No effective therapy has yet developed for liver fibrosis/cirrhosis by directly inhibiting the accumulation of extracellular matrix. This study was undertaken to determine the effect of tetrandrine in rat model of liver fibrosis induced by carborn tetrachloride (CCl4) administration intraorally. Tetrandrine, a calcium channel blocker, is anti-inflammatory constituent of the families Menispermaceae and Ranunculaceae, which have been used as folk remedies in China. Repeated administration of CCl4 for 14 weeks to rats induced liver fibrosis with steatosis. Rats were killed after 4, 8 or 14 weeks of treatment with CCl4, CCl4 tetrandrine (30 mg/kg) or CCl4 tetrandrine (50 mg/kg). The histopathological findings of liver were observed semi-quantitatively by light microscopy and volume percentage of the collagen deposition was determined by image analyzer. Tetrandrine inhibited collagen deposition induced by CCl4 administration, as shown by less severe steatosis and fibrosis and significantly decreased volume percentage of collagen fibers in CCl4 tetrandrine treated animals compared with CCl4 only group. Thus, the administration of tetrandrine holds great promise for treating subjects with liver fibrosis/cirrhosis as a result of chronic hepatic injury.

Development of supervoltage treatment machine may minimize skin reaction by skin-sparing effect, but skin damage is still one of “the dose limiting factor” in radiation therapy. In spite of these importance, systemic histopathologic studies of skin in similar conditions which used in clinical treatment has not been performed so far. 60 mice were irradiated with conventional fraction (200x5/wk) and whole abdominal field (2x3 cm, from symphysis pubis to xyphoid process). Used machine was 250 KV, 24 mA. orthovoltage x-ray machine. Histopathological changes of acute skin reaction at the level of total irradiation dose were analyzed and possible mechanism of later chronic changes were investigated. Obtained results are as follows 1. In 1,000 rad irradiated group, only mild epidermal edema is noted. 2. In 2,000 rad irradiated group, slightly decreased number and size of hair follicles and appendages, dermal edema and scanty infiltration of inflammatory cells are visible. 3. In 3,000 rad irradiated group, marked increased capillary congestion and prominent infiltration of inflammatory cells are observed. 4. In 4,000 rad irradiated group, vascular wall thickening with proliferation of endothelial cells are prominent. Dermal thinning and hyalinization are newly developed. 5. In 5,000 rad irradiated group, complete desquamation of epidermis is not seen, despite of acceleration of all above mentioned changes.

6.The Study of Motion of Two Components in Bipolar Hemiarthroplasty

The bipolar hemiarthroplasty is one of the treatment methods of the avascular necrosis of the femoral head and the fracture of the femur neck. The mechanism of bipolar hemiarthroplasty is intended to distribute the forces at the site of the inner and outer articulation, and theoritically diminish acetabular wear and produce a painless arthroplasty. The authors analyzed motion of two components in 23 cases of the bipolar hemiarthroplasty, performed at the Department of Orthopaedic Surgery, Korea University Hospital, between January, 1985 and January, 1993 with average 47 months follow up(range 24 to 84 months). The results obtained were as follows: 1. In the motion of the two components, inner bearing motion was average 11.5 degrees(from 1 to 29 degrees) and outer bearing motion was average 21.4 degrees(from 3 to 45 degrees). 2. The inner bearing motion was highest at 12 months with average 16 degrees and outer bearing motion was lowest during the same period with average 15 degrees. During the follow up the inner bearing motion was decreased whereas outer bearing motion was increased. 3. The inner or outer bearing motion of bipolar component was no correlation with age, sex and clinical result.

Inflammatory pseudotumor of the liver is a rare benign tumor with microscopic finding of fibrous stroma and chronic inflammatory cell infiltration. Predominance of plasma cells, histiocytes, lymphocytes, some eosinophils and whorled pattern of fibrosis is often characteristic. Due to similar radiologic appearance of hepatocellular carcinoma, inflammatory pseudotumor of the liver was often misdiagnosed and hepatic resection is often performed before preoperative tissue diagnosis. We report a case of inflammatory pseudotumor, which was a 47-year-old woman with fever, upper aMominal pain and weight loss, diagnosed by sonoguided liver biopsy and treated with antibiotic therapy only without surgery. After two weeks of treatment, the radiologic image of the mass was almost disappeared with improvement of previous symptoms. This opportunity and the possible effectiveness of antibiotic treatment should keep in mind in the differential diagnosis of the hepatic mass with similar radiologic appearance of hepatocellular carcinoma.

9.Experience of Smoking Cessation.
Journal of Korean Academy of Adult Nursing 2002;14(4):521-531
PURPOSE: This study was to identify the meaning of the lived experiences, to describe of the meaning structures and to develop the strategies of nursing intervention centering to these meanings of the smoking cessation. METHOD: This study was derived from a phenomenological analytic method suggested by Giorgi. The participants in this study were five adults who had the previous experience of smoking cessation. The data were collected from September of 2001 to April of 2002 through systemic interviews and participatory observations. Average of five interviews were performed, and each interview lasted an hour and half. RESULT: The meaning of smoking cessation was categorized with nine components. That is (1) obstinacy of the habit of smoking ; difficulty of endurance, succumb to temptation of smoking, repetition of smoking and smoking cessation, habit-forming. (2) Bring about a symptom of improving ; took place headache, expectoration of sputum, sense of instability. (3) Waver in worthy ; doubts about smoking cessation, ridiculed smoking cessation. (4) Be narrowed social life ; become estranged from friends. (5) Futility ; unnecessary, harm. (6) Self-repression ; occurred indomitable mind, strong will, endurance. (7) Gratification ; self-admiration, receive praise from family. (8) Delightfulness ; clean in body and clothes, be disgusted with the foul order of smoking. (9) Improvement in welfare ; a clear mind and good memory, improve in health, have a good appetite. CONCLUSION: The nursing intervention must be focused on these concerns to accomplish successful smoking cessation program.

Maffucci's syndrome is a congenital, non-hereditary mesodermal d splasia manifested by multiple enchondromas and hemangiomas. Several case reports and reviews indicate that there is a tendency toward malignant transformation of the enchondroma. The incidence of malignancy may be as high as 30%. We report a case of 10-year-old female with multiple hemangiomas on the face, palms, and soles and skeletal chondromatoses of the multiple bones.
