BACKGROUND: This study was performed to determine and compare the practice patterns of management of hypertension of the internists and family physicians in general hospitals and to compare them according to the JNC V guidelines. METHODS: Questionnaires were mailed to total 964 of internists and family physicians in general hospitals during May, 1996. 217 of them were returned with the response rate of 23.5%. Chi-square test and Fishers exact test were performed to examine the statistical difference between two groups. RESULTS: The mean age of the respondents was 39.1 and 77.9% of them were male. 65.4 % of hospitals for respondents were located in metropolitan cities. Concerning the number of measurements of blood pressure, 0.5% of the respondents measured just once before confirmation of the diagnosis. Items for physical examinations for initial evaluation were as follows; cardiac auscultation(94.0%), measurements of body weight and height(58.9%), abdominal examination(52.8%), auscultation for carotid bruit(41.7%), fundoscopic examination (25.6%). Regarding the laboratory tests, the frequency of evaluation of all item were higher than that of the physical examinations. For initial drug therapy, calcium channel blockers and ACE inhibitors were the most frequently chosen mediations. No difference was found between two specialties or tertiary and secondary hospitals in this trend. With educations for the life-style modification, 60-80% of the respondents educated the patients. No difference was found between two specialties except one item. CONCLUSIONS: As a whole the JNC V guidelines were not followed faithfully for the management of hypertension.

Among the efficient cancer treatments, photodynamic therapy (PDT) is one of the therapies inducing rapid apoptosis of cancer cells while causing minimal damage to surrounding normal tissue. We studied the effect of PDT on the adenocarcinoma in BALB/-c mice of homograft model, and the following results were obtained. Apoptosis occurred up to 3 mm in depth from the surface in the first 1 hour after PDT applied, and subsequently the counts were increased in the deeper portion. A remarkable apoptosis observed up to 6 mm in depth shows that the light in use could not penetrate more than 6 mm of tissue. Tissue necrosis was identified in the deeper area of the tumor 6 hours later or thereafter. This necrosis seemed to occur as an indirect effect of vascular obstruction resulting from the damage of endothelial cells which was induced by selective collection of photosensitizer in the endothelial cells of newly forming vessels as well as in the cancer cells. These results indicate that the effective depth of PDT is greater than the depth of light penetration.

This study was investigated to compare the staining resistance of soft denture liners. Specimens wee made of Coe-soft. Coe-Comfort, Soft-liner, Visco-gel, and were stored in 1% methyleneblue solution for 24 hours. The amounts of color change before and after treatment with mono-poly and thermocycling were measured by colorimeter(TC-6FX, Tokyo Denshoku Co. Ltd, Japan) for evaluation of staining resistance. The following conclusions were drawn from this study. 1. The staining resistance of Visco-gel was increased, but there was no changer of staining resistance in Coe-soft, Coe-comfort, and Soft-liner after treatment with monopoly. 2. The staining resistance of the Coe-comfort was the least in all soft denture liners. 3. The staining resistance of Visco-gel and Soft-liner were decreased after thermocycling.

A case of cutaneous sarcoidosis in the 66 year-old Korean female patient is presented. She shows typical skin manifestations of plaque type in the absence of other common objective evidence of systemic involvement. Diagnosis was confirmed by charcteristic histological findings and positive Kveim test with the support of other compatible clinical and biochemical findings. She had been followed up for 3 years since the first visiting. Recently chest X-ray, slit lamp examination and skin biopsies were taken again, but failed to reveal any significant interval changes.

Thrombosed capillary or vein is a dome-shaped or slightly lobulated moderately firm, blue black nodule arising either abruptly or gradually. There may be a rim of erythema or brownish pigmentation around it. Its clinical features are similar to a malignant melanoma. We report a case of thrombosed capillary or vein associated with angiokeratoma in 44-year old male patient who has a bean sized, dome-shaped, blue-black nodule and multiple hyperkeratotic pinhead sized dark red papules un scrotum.

The purpose of this study is to evaluate the influence of the extent of involvement in the results of cementless THA in patients with idiopathic AVN of the femoral head. We reviewed 70 hips (52 patients) who had undergone cementless THA for idiopathic AVN of the femoral head. Anatomic femoral components were used in 43 hips and Harris Galante porous prosthesis were employed in 27 cases. The hips were classified according to International Classification (Association Research Circulation Osseous). The length of the follow-up period ranged from 3 to 5 years (average 53.5 months). Preoperative and postoperative clinical documentation and radiographs were evaluated. Statistical analysis was performed on the results of three analysis groups (Group A, comparison of results among Stage IIIA, IIIB, IIIC, and IV; Group B, between stage III and IV; Group C, between IIIA+IIIB and IIIC + IV). Of the 70 hips in the present study, there were 47 hips in stage III (IIIA, 15; IIIB, 19; IIIC, 13) and 23 hips in stage IV. The average postoperative Harris hip score at the time of study was 91.5 (Analysis Group C, p=.009). Femoral subsidence of more than 5 mm occurred in 5 hips (7.1%). Two hips were in Stage IIIC and three hips were in Stage IV (Group C, p=.024). The hips lower than -10 on Engh's index were present in one hip in Stage IIIC and three hips in Stage IV (Group C, p=.011). This study demonstrated that the clinical and radiological results of cementless THA were poor when the extent of involvement was greater or in the case of late stage subjects, particularly those above IIIC (p<05), with avascular necrosis of the femoral head.

This study was performed to investigate the effects of impression method and design of the retainer on the stress of abutment tooth in distal extension RPD. Three different types of direct retainer such as Akers clasp. RPI clasp, and wrought wire clasp were designed . Stress on the abutment tooth was measured and analyzed with strain gauge method. Impressions were anatomic impression technique and functional impression technique. The following conclusions were drawn from this syudy. 1.The stress at the abutment tooth on all RPD was decreased in functional impression except RPI clasp retained RPD. 2.The stress at the abutment tooth on RPI clasp retained RPD was the most smallest in anatomic impression 3.While load is increase the stress at the abutment tooth was increased, but the change of stress at the buccal side of abutment tooth was not too much in functional impression.

Among the causes of pure red cell aplasia, human parvovirus B19 has been shown to be cytotoxic to erythroid progenitor cells in the bone marrow associated with chronic hemolytic anemia with rapidly dividing erythroids and persistently to be suppression of erythropoiesis in immunocompromised individuals related with failure to produce neutralizing antibody to the virus. In a patient with hereditary spherocytosis presenting acute onset of reticulocytopenia during hospitalization, who had shown severe anemia and prodromal symptoms including fever, fatigue and dizziness, infection of parvovirus Bl9 was proven by the presence of IgM and IgG antibodies to parvovirus Bl9, the detection of viral DNA using PCR technique in her serum and the decreased erythroid cells, especially late normoblasts in bone marrow, Also in the other who was diagnosed as hereditary elliptocytosis and complained of fever, headache, abdominal pain and diarrhea, an episode of reticulocytopenia and the nearly absence of late normoblasts in the bone marrow were observed. IgM antibodies to parvovirus Bl9 and the viral DNA were detected in her serum, too.
