We report a case of 64-year-old female patient who has had factitious skin lesions for 20 years. She complained formification sense and severe itching on her face. These symptoms were improved with squeezing and bleeding. There were scuare shaped ulcerated nodule on the right cheek and white depressed scar on the left cheek. She was treated with wet dressing and occlussive dressing, and skin lesions were nearly cleared within 3 weeks, but new lesion appeared. Pimozide 2mg #1 p.o were given under the diagnosis of delusion of parasitosis from June, 1984. Her symptoms were improved without recurrence till now. Treatment with pimozide in monosymptomatic hypochondriacal syndrome is discussed.

Human untreated costal cartilage was compared with lyophilized human costal cartilage which was treated with defatting solution for 48 hours and freeze drying for 72 hours (-70degree C, 10??bar) on the tendency of distortion. All cartilages, which were taken from six cadavers, were carved 5x5x30mm in size on principle of the balanced cross section. Their distortions were evaluated by two methods at intervals of one week, one month, three months, six months after experiment. At first, the degree of distortion was grossly graded with four steps: grade O; no distortion / grade I; minimal distortion / grade II; moderate distortion / grade III; severe distortion. Second method is measurement and quantification of distortion in the horizontal and vertical plane of cartilage.Untreated cartilage is shown to be an unsatisfactory material, with only three(12%) of the 25 cartilages being cosmetically acceptable(grade 0 and 1) after 6 months. In lyophilized cartilage, 18(94%) of the 19 cartilages were cosmetically acceptable(grade 0 and 1) at 6 months. This figure is highly significant(p<0.01). In another method, distortion in the horizontal(h) and vertical (v) planes of cartilage were measured, and mean values of ???? were calculated. In untreated group, the mean values of ???? were 0.82 at 1 week, 0.91 at 1 month, 1.13 at 3 months, and 1.31 at 6 months. In lyophilized group, the mean values were 0.27 at 1 week, 0.29 at 1 month, 0.40 at 3 months and 0.47 at 6 months. All values were statistically significant(p<0.01).

Bony defect is one of the most common problems in craniomaxillofacial surgery. Although aurogenous bone graft is the best choice for the treatment of bone defect, it provides many problems such as donor site morbidity, irregular absorption, and limited amount of harvest. To overcome the shortcomings of autogenous bone graft many bone substitutes have been introduced. The ideal bone substitution is to have characteristics such as cheap, easy to obtain, rapid fusion to recipient bone, hard structure, long maintenance of shape and volume, low infection rate, and low exposure rate. Among those bone substitutes which have been widely used we chose lyophilized cartilage allograft because of low antigenecity, low resorption rate, easiness of carving and ling term preservation. From August 1993 to August 1997, 66 patients had been performed craniomaxillofacial reconstruction with lyophilized cartilage allograft. Orbital wall reconstruction and correction of enophthalmos were 24, correction of cleft lip and nose deformity were 19, temporal augmentations were 7, and others 16. Complications such as infection, exposure were not common. And partially removed cartilage was proved some calcification. Radiologic follow-up presented well positioned lyophilized cartilage allograft. Two radiologic works revealed haziness of bone density at the site of cartilage allograft. This suggests the ossification of lyophilized cartilage allograft. Together with liw infection rate, low exposure rate, and good framework for osteoconduction, lyophilized cartilage allograft are regarded as one of the good bone substitutes.

Screening test of Human Immunodeficiency Virus(HIV) infection was introduced on Korean Blood Donor Test Program in July 1987, and the test results between July 1987 and December 1990 were reported on the Korean Journal of Blood Transfusion on May 1992. Moreover, we assessed anti-HIV ELISA screening test result of 3,905,986 blood donors donated at Korean Red Cross Blood Centers between January 1991 and December 1993. The seropositivity of anti-HIV ELISA screening test was 0.26% in 1991, 0.30% in 1992 and 0.18% in 1993.0.15% of all donors in 1991 was reactive repeatedly, and 0.15% in 1992 and 0.08% in 1993. The prevalence of HIV infected donors confirmed by Western Blot Assay was 0.0003% in 1991, 0.0015% in 1992, and 0.0009% in 1993. The sero-positivities of anti-HIV screening tests with AIDSDIA reagent and HIVIRO reagent were 0.32% and 0.17% and the difference was significantly(p<0.05). The sero-positivities of ELISA screening and Western Blot. Assay detecting anti-HIV were lower in soldier group than in non-soldier donor group (p< 0.05).

Treatment of infected nonunions of long bone is confronted with various difficult problem, e.g. eradication of infection and osseous union even in the presence of devastating infection. To solve this problem various method were proved including exerternal fixation, electrical stimulation and functional casting method with some success. Intreating these difficult infected nonunions, we adopted another program which includes through debridment of the infected and necrotic soft tissue and bone, autogenous bone graft, rigid internal fixation of fragments and ope.n drainage of the wound until union of the fracture. We treated 8 cases of infected nonunions with this method from march, 1980 to september 1983 and results are as follows: 1. Satisfactory union was obtained within average 5 months. 2. In some cases pus drainage continued even after osseous union but it was easily controlled after removal of fixation devices. 3. After bone union and removal of internal fixation devices, some kind of protective measures, e.g. crutches and braces were used for about 6 montes to prevent refracture. 4. In conclusion our method is considered to be an effctive means is treating infected nonunion of fractures.

BACKGROUNDS: The Rh antigens are important m clinical practice. The classification of Rh phenotype is usually based on the antigen detection done by conventional serologic method, but it has many limitation such as delicate grading of antigen expression. Recently, Flowcytometry has been introduced in immunohematology to detect and quantitate cell bound immunoglobulins to assess blood cell antigens and related antibodies. So, we tried these method to detect Rh(D) antigen and measure its density and evaluated the possibility of clinical usage. MATERIALS AND METHODS: We performed a flowcytometric analysis for the expression of D antigen in D-positive, negative and weak D group in indirect immune fluorescence assay by using polyclonal antibodies. We measured the intensity of immunofluorescence as a degree of antigen density and analysed the difference of mean channel fluorescence value(MCF) among these groups. RESULTS: Weak D groups had the lower fluorescence than D-positive group, while D-negative sample showed the same fluorecence as negative ntrol. The difference of fluorescence intensity of D antigen between that of C antigen were not observed and were statistically insignificant. CONCLUSION: Flowcytometry appear to be a good tool for antigen density measurement in immunohematologic areas and shows the possibility of application to other aspect.

BACKGROUND: Cancer invasion and metastasis require the dissolution of the extracellular matrix in which several proteolytic enzymes are Involved. One of these enzymes is the urokinase - type plasminogen activator(u-PA), and plasminogen activator inhibitors(PAI-1, PAI-2) a]so have a possible role in cancer invasion and metastasis by protection of cancer itself from proteolysis by u-PA. It has been reported that the love]s of u-PA and plasminogen activator inhibitors in various cancer tissues are significantly higher than those in normal tissues and have significant correlations with tumor size and lymph node involvement Here, we measured the concentration of plasma u-PA and PAI- 1 antigens in the patients with lung cancer and compared the concentration of them with histologic types and staging parameters. METHODS: We measured the concentration of plasma u-PA and PAI-1 antigens using commercial ELISA kit in 37 lung cancer patients, 21 benign lung disease patients and 24 age-matched healthy controls, and we compared the concentration of them with histologic types and staging parameters in lung cancer patients. RESULTS: The concentration of u-PA was 1.0α0.3ng/mL in controls, 1.0α0.3ng/mL in benign lung disease patients and 0.9α0.3ng/mL in lung cancer patients. The concentration of PAI-1 was 14.2α6.7ng/mL in controls, 14.9α6.3ng/mL in benign lung disease patients, and 22.1 α9.8ng/mL in lung cancer patients. The concentration of PAI- 1 in lung cancer patients was higher than those of benign lung disease patients and controls. The concentration of u-PA was 0.7α0.4ng/mL in squamous cell carcinoma, 0.8α 0.3ng/mL in adenocarcinoma, 0.9ng/mL in large cell carcinoma, and 1.1α0.7ng/mL in small cell carcinoma. The concert traction of PAI-1 was 22.3α7.2ng/mL in squamous cell carcinoma, 22.6α9.9ng/mL in adenocarcinoma, 42ng/mL in large cell carcinoma, and 16.0α14.2ng/mL in small cell carcinoma. The concentration of u-PA was 0.74ng/mL in stage I, 1.2α0.6ng/mL in stage II, 0.7 α 0.4ng/mL in stage IIIA, 0.7α0.4ng/mL in stage IIIB, and 0.7α0.3ng/mL in stage IV. The concentration of PAI-1 was 21.8ng/mL in stage I, 22.7α8.7ng/mL in stage II, 18.4 α4.9ng/mL in stage IIIA, 25.3α9.0ng/mL in stage IIIB, and 21.5α10.8ng /mL in stage IV. When we divided T stage unto T1-3 and 74, the concentration of u-PA was 0.8α 0.4ng/mL in T1-3 and 0.7α0.4ng/mL in T4, and the concentration of PAI-1 was 17.9α 5.6ng/mL in T1-3 and 26.1α9.1ng/mL in T4. The concentration of PAI-1 in T4 was significantly higher than that in T1-3. The concentration of u-PA was 0.8α 0.4ng/mL in M0 and 0.7α0.3ng/mL in Ml, and the concentration of PAI-1 was 23.6α8.3ng/mL in M0 and 21.5α10.8ng/mL in M1 CONCLUSIONS: The plasma levels of PAI-1 in lung cancer were higher than benign lung disease and control, and the plasma levels of PAI-1 in 74 were significantly higher than T1-3. These findings suggest involvement of PAI-1 with local invasion of lung cancer, but it should be confirmed by the data on comparison with pathological staging and tissue level in lung cancer.
