Although platelet have been implicated in the pathogenesis of the thrombotic disease, the platelet aggregability was not well studied in Korea. Author measured platelet aggregability in 103 clinical cases including 30 healthy volunteers to evaluate the platelet function and the effect of Aspirin and Dipyridamole on aggregability in Korean. 24 patients with cerebral thrombosis, 24 patients with ischemic heart disease and 25 patients with hypercholesterolemia were included for this study. Aggregation tests were performed at three final concentrations of epinephrine(10microM/L) and ADP(4 microM/L, 10 microM/L) with platelet aggregometer which was made by Chrono-Log Corp. in all cases. Platelet aggregations were measured in patients who were treated with Aspirin, Dipyridamole and combined treatment of Aspirin and Dipyridamole respectively. The following results were obtained. 1) The mean maximal platelet aggregability in the normal subjects induced by 10 microM/L epinephrine was 59.3+/-24.26%, 66.6+/-14.00% in Bm and 62.5+/-19.30% in B5 in induction by 4 microM/L ADP, and 77.2+/-8.99% in Bm and 76.6+/-9.83% in B5 in induction by 10microM/L ADP. 2) The mean maximal platelet aggregability in patients with cerebral thrombosis induced by 10 microM/L epinephrine was 89.2+/-7.33%, 78.8+/-9.41% in Bm and 78.5+/-9.93% in B5 in induction by 4 microM/L ADP, and 86.4+/-7.69% in Bm and B5 in induction by 10 microM/L ADP. The results showed significantly elevated platelet aggergability than that of normal subjects(p<0.01). 3) The mean maximal platelet aggregability in patients with ischemic heart disease induced by 10 microM/L epinephrine was 88.1+/-11.99%, 78.2+/-12.50% in Bm and B5 in induction by 10 microM/L ADP. The results showed significantly elevated platelet aggregability than that of normal subjects(P<0.01). 4) The mean maximal platelet aggregability in patients with hypercholesterolemia induced by 10 microM/L epinephrine was 86.8+/-15.99%, 82.7+/-11.19% in Bm and 82.0+/-12.87% in B5 in induction by 4 microM/L ADP, and 88.5+/-11.47% in Bm and B5 in induction by 10 microM/L ADP. The results showed signifcantly elevated platelet aggregability than that of normal subjects(P<0.01). 5) The mean maximal platelet aggregability in patients with thrombotic disease was studied by Dipyridamole administration. The platelet aggregability induced by epinephrine before administration was 90.9+/- 8.52% and after administration it was 78.9+/-15.68%, and the results showed that Dipyidamole lowered aggregability significantly. The platelet aggregability induced by 4 microM/L ADP before administration was 84.0+/-11.90% in Bm and B5 and after administration it was 78.0+/-11.44% in Bm and B5, and the results showed that Dipyridamole lowered aggregability but not significant. The platelet aggregability induced by 10 microM/L ADP before administration was 89.2+/-10.39% in Bm and B5 and after administration it was 80.5+/-8.44% in Bm and B5, and the results showed that Dipyridamole lowered aggregability significantly. 6) The mean maximal platelet aggregability in patients with thrombotic disease was studied by Aspirin administration. The platelet aggregability induced by epinephrine before administration was 91.0+/-4.79% and after administration it was 47.6+/-17.72%. The platelet aggregability induced by 4 microM/L ADP before administration was 84.6+/-10.37% in Bm and B5 and after administration it was 72.6+/-11.85% in Bm and 65.3+/-15.97% in B5. The platelet aggregability induced by 10 microM/L ADP before administration was 84.9+/-6.30% in Bm and B5 and after adminstration it was 77.7+/-8.60% in Bm and 75.0+/-8.89%. The results showed that Aspirin lowered aggregability markedly. 7) The mean maximal platelet aggregability in patients with thrombotic disease was studied by combined administration of Aspirin and Dipyridamole. The platelet aggregability induced by epinephrine before administration was 86.7+/-13.77% and after administration it was 36.7+/-14.01%. The platelet aggregability induced by 4 microM/L ADP before administration was 81.5+/-12.93% in Bm and 80.6+/-14.15% in B5 amd after administration it was 54.7+/-17.27% in Bm and 44.6+/-21.17% in B5. The platelet aggregability induced by 10 microM/L ADP before administration was 87.8+/-10.11% in Bm and B5 and after administration it was 65.7+/-13.59% in Bm and 62.0+/-16.42% in B5. The results showed that combined administration of Aspirin and Dipyridamole lowered aggregability significantly and the results were lower than that of normal subjects. 8) The effects of combined treatment of Aspirin and Dipyridamole showed marked reduction of platelet aggregability than that of single treatment of Aspirin or Dipyridamole in thrombotic disease.

BACKGROUND: Benign paroxysmal positional vertigo (BPPV) is the most common peripheral vestibular disorder that often resolves spontaneously. It was long believed that the condition was caused by inorganic particles in the cupula of the posterior semicircular canal. Management of this condition includes medication, surgery, physical exercise and more recently particle repositioning maneuvers. Among the various therapies, exercise therapy (ET) reported by Brandt-Daroff was based on the theory of cupulolithiasis and is designed to treat BPPV through dispersion of the debris from the cupula. METHODS: Fifty four patients with BPPV were treated with ET to determine the effectiveness. Fifteen additional patients with BPPV were treated with only medication and served as a control group. RESULT: Forty eight of 54 cases (88.9%) treated with ET showed improvement after 2 weeks. With medication alone, 8 of the 15 cases (53.4%) showed improvement after 2 weeks. CONCLUSIONS: The most important benefit of this maneuver seemed to be more expedient recovery than that with medication alone.

Human Papillomaviruses(HPVs) are regarded as sexually transmitable and closely associated with precancerous lesions or invasive cancers of the vulva, vagina, and cer V1X. In situ hybridization, besides showing higher sensitivity, allowed the identification of specific viral types. We studied 12 cases of condylomata accuminata for HPV typing by in situ hybridization techenique. Ten cases(83.3 % ) showed positive for HPV type 6/11, and 2 cases(16.7% ) were positive for HPV type 16/18.

Scleroderma is a connective tissue disease characterized by excessive accumulation of collagen in skin and visceral organs due to increased collagen production by scleroderma fibroblasts. The basic etiology of this collagen accumulation is not known. We examined the expression of various extracellular matrix genes in cultured fibrolasts using Northern blot and slot-blot hybridization. The scleroderma fibroblasts exhibited characteristic mRNA size of extracellular matrix genes and prominanty increased type I and III procollagen mRNAs levels compared to control fibroblasts cultures from univolved skin. The ratios of type I /IE procollagen in scleroderma cell lines were not so much different to the controls. These results indicate that increases of collagen biosynthesis in scleroderma can be a accounted for, at least in part, by an increased content of transcriptable type I and type JE procollagen mRNAs, both.

Image-guided localized, water-suppressed in vivo 1H MR spectroscopic studies were performed on the brain tumors in 3 patients. In all 3 patients, in vivo 1H MR spectra in brain neoplastic tissues revealed that the signal intensities of N-acetylaspartate (NAA) choline (Cho) resonances were decreased and increased, respectively, comparing with healthy normal tissue. A distinct lactate signal was identified in all three patients. A ratio that the observed metabolite alterations from localized, water-suppressed in vivo 1H MR spectroscopy can be useful as an index of brain tumors, and that the technique is clinically to highlight as one promising modalities in brain tumors for more accurate diagnosis.

PURPOSE: The need for continuing Growth Hormone(GH) replacement after adolescence in patients with childhood-onset GH deficiency has been recognized. The purpose of this study was to evaluate the abnormalities of lipid profiles in young adults with childhood-onset hypopituitarism who discontinued GH therapy after the completion of height growth. METHODS: Nine male patients(mean age:22.4+/-3.3 years) with childhood-onset hypopituiatarism in whom GH treatment had been discontinued after final height was achieved were included. Their body mass index(BMI) and serum levels of total cholesterol, triglyceride(TG), high-density lipoprotein(HDL) cholesterol, and low-density lipoprotein(LDL) cholesterol were measured. The relationships of duration after GH discontinuation, age, and BMI to lipid profiles were anaylzed. RESULTS: BMI increased significantly from 21.8+/-1.9 kg/m2 before GH discontinuation to 23.0+/-3.0 kg/m2 after GH discontinuation(P<0.05). Serum levels of total cholesterol, TG, HDL cholesterol, and LDL cholesterol were 217.3+/-33.4, 237.8+/-128.2, 42.1+/-7.1, and 127.4+/-27.2 mg/dL, respectively, 3.1+/-2.0 years after GH discontinuation. Percentage of patients who had total cholesterol > or = 200 mg/dL, TG > or = 150 mg/ dL, LDL cholesterol > or = 140 mg/dL, and HDL cholesterol < or = 40 mg/dL were 77.8%, 88.9%, 44.4%, and 33.3%, respectively. All subjects had some abnormalities of lipid profiles. A significant positive correlation was found between duration after GH discontinuation and serum levels of total cholesterol and TG(r=0.84, P<0.01; r=0.83, P<0.01). A significant positive correlation was also found between age and serum levels of total cholesterol and TG(r=0.86, P<0.01; r=0.81, P<0.01). There were no correlations between BMI and serum lipid levels. CONCLUSION: Most of young adult patients with childhood-onset hypopituitarism had abnormal lipid profiles by 1-5 years after discontinuation of GH treatment. These data suggest that continuous GH treatment after completion of height growth is necessary.

BACKGROUND: Methods to detect and quanitify Mycobacterium leprae(M. leprae)are needed for studies involving the epidemiology, pathogenesis, and chemotherapy of leprosy. Serological assays and skin tests lack the sensitivity and specificity to serve as diagnostic tool for M. leprae infection. The polymerase chain reaction(PCR) based on the selective amplification of an 530-bp frangment of the gene encoding the proline-rich antigen of M. leprae was performed with sections of fixed or frozen biopsy samples from leprosy patients. OBJECTIVE: This study was done to investigate the applicability of PCR for the detection of low numbers of M. leprae in tissues and peripheral blood. METHODS: The PCR was used to amplify a 530-base-pair M. leprae DNA with the thermoxtable Taq DNA polymerase. RESULTS: The In frozen skin tissues and peripheral blood of leprosy patients. relatively high detection rates of PCR products was achieved by using direct gel analysis as well as Southern blot hybridization. CONCLUSION: These results suggest that PCR amplification for the detection of M. leprae may be useful for the epidemiologic study of large papulations as well as coinical astudies on the individual patients.
