Bacteriological index(BI) was calculated by slit-skin smears taken from the earlobe and the dorsal surfaces of the proximal phalanges of the index finger and of the great toe in 110 lepromatous leprosy patients who have been treated regularly by antileprosy chemotherapy. The bacteriaI indices from the three sites were compared, and the results were as follows. 1) Sixteen patients whose BI of the earlobe smear was 4. 0 in average shawed the highest degree of positivity of M. leprae in the smears taken from the finger and the great toe. 2) ln seventy-four patients whose BI of the earlobe smear was l. 0 or higher, eight (10.8%) showed higher BI in smears taken from both the finger and the great toe, fifteen (20. 3%) and twenty-seven(36. 5%) showed approximately the same BI in smears taken from the finger and the great toe, respectively, 3) In thirty-six patients whose BI of the earlobe smear was negative, twelve (33. 3%) showed higher BI in smears taken from both the finger and the great toe. 4) The mean value of BI of the three sites was 3.7 in the earlobe, 3. 2 in the finger and 3. 0 in the great toe. Comparing the BI of the three sites, the finger and the great toe were found to have comparable BI with the earlobe, although the BI of the earlobe was highest. The authors concluded that it was quite reasonable to include the finger and the great toe in slit-skin smears for M. leprae identification, particularly when the BI of the earlobe was negative. A follow-up investigation seems mandatory.

We have experienced a 50-year-old male patient, who died of multiple metastatic nodular melanoma which had the primary lesions on the right hallux and forefoot with eventual involvement of skin and internal organs. An autopsy was performed for the evidence of metastatic features of the internal organs and their spreading routes, with concurrent histopathologic findings. The autopsy findings revealed diffuse metastases to the ipsilateral femoral and inguinal lymph nodes via ascending vascular channels and to the internal organs: 1. The heart had multiple metastatic lesions on the pericardium and right ventricular wall. And the mediastinal, periaortic and periesophageal lymph nodes were also involved. 2. The both lungs were moderately indurated and focally discolored, and showed metastatic lesions in the right lower lobe and hilar areas, Melanoma cells were diffusely invaded to the interstitia and alveoli. 3. The right 5th and 6th ribs showed the invsion of melanoma cells on their bone marrows, periostia, and Haversians canals. 4. The liver was enlarged and showed multiple various sized nodules on the surface with adesion to the parts of peritoneum, omentum and diaphragm. Melanoma cells were seen mostly on and around the sinusoidal spaces and parenchyma. 5. The stomach wall had an ulcerated metastatic lesion and the melanoma cells invaded deeply into the muscle layer. 6. The pancreas was normal in its size and shape but had multiple metastatic lesions on the head and body with melanoma celi infiltration. 7. The both kidneys were grar ular surfaced and showed two metastatic lesions on the right renal cortex and two on the left. Renal tubules and parenchyma were widely invaded by melanoma cells but the glomerular tufts were intact. 8. The adreral and thyroid glands showed four and two metastatic lesions respectively and diffuse invasion of melanoma cells into the parenchyma. 9. The brain was normal in gross appearance, but the cortex was edematous and showed settered melanoma cell infiltration.

To investigate effects of cytokines on rheumatoid synovial cells, proliferation and expression of cytokine and metalloproteinase genes were studied with the primary culture of rheumatoid synovial cells which was treated with TNF-alpha, GM-CSF, TGF-alpha, PDGF and IL-B. By [3H] thymidine incorporation assay, TGF-beta and PDGF increased proliferation of synovial cells by 1.5 and 2.5 folds respectively. Cytokine gene expression was assessed by RT-PCR. Rheumatoid synovial cells expressed constitutively TGF-beta and IL-B at a high level and IL-1B, GM-CSF, and MIP-1a at a relatively low level. TGF-beta, GM-CSF and PDGF increased IL-B expression. Expression of pro-inflammatory cytokines and chemokines was increased by GM-CSF and PDGF. Both GM-CSF and PDGF increased the expression of IL-1B, GM-CSF MIP-la and IL-8. In addition, GM-CSF enhanced expression of TNF-alpha. Stromelysin and collagenase are the major proteinases responsible for destruction ot joints in rheumatoid arthritis (RA). These genes were expressed constitutivefy in rheumatoid synovial cells. In summary, PDGF and GM-CSF may piay an important role by inducing or increasing expression of IL-1B, TGF-beta and PDGF by increasing proliferation of rheumatoid synovial cells.

PURPOSE: Many articles have proposed that osteonecrosis of the femoral head (ONFH) is caused by fat embolism or intravascular coagulation linked to hyperlipidemia. To determine whether hyperlipidemia is an associated factor for ONFH, serum lipid levels were measured. MATERIALS AND METHODS: Nighty-eight patients presenting with ONFH and 110 controls were investigated. We compared the average value of serum lipid levels and the incidence of hyperlipidemia of the two groups. RESULTS: ONFH group showed generalized increase in lipid level and statistically significant difference in the average value of total cholesterol (P=0.0001), HDL-cholesterol (P=0.0261) and phospholipid (P=0.0465) compared with the control. The incidence of hyperlipidemia of the two groups showed statistically significant difference in HDL-cholesterol (P=0.019) and triglyceride (P=0.024). CONCLUSION: Hyperlipidemia seems to be associated with pathogenesis of ONFH. We speculated that hyperlipidemia might be a contributing factor of ONFH. Hyperlipidemia may play a role as a triggering factor in the pathogenetic process that results in osteonecrosis. However, it can not be ruled out that secondary hyperlipidemia might be a finding following ONFH.

BACKGROUND/AIMS: Liver biopsy has been used to evaluate the degree of hepatic fibrosis in patients with chronic liver diseases. It is important to assess liver fibrosis when following the course of chronic liver diseases. Histopathological examination of percutaneous biopsy specimens is invasive and is also of questionable value because of the heterogenous distribution of pathological changes in the liver. Therefore, non-nvasive methods to determine the progress of liver fibrosis are needed. Serum hyaluronic acid and type IV collagen are known to be related to hepatic fibrosis. This study was performed to evaluate the clinical usefulness of serum hyaluronic acid and type IV collagen measurement as a differential point in patients with chronic liver diseases and early cirrhosis. METHODS: This study included 109 patients with chronic liver diseases caused by various etiologies. Liver biopsy and histopathological classification were done in all patients. Serum hyaluronic acid and type IV collagen were measured by one-tep sandwich binding protein assay and one-tep sandwich enzyme immunoassay. RESULTS: The concentrations of hyaluronic acid and type IV collagen in the early cirrhosis group (208.5+/-186.4 ng/mL, 242.1+/-162.8 ng/mL) were significantly higher (p<0.01) than those in the normal and fatty liver group (26.3+/-21.7 ng/mL, 79.2+/-28.8 ng/mL), mild chronic hepatitis group (22.8+/-15.4 ng/mL, 125.5+/-79.7 ng/mL), moderate to severe hepatitis group (66.3+/-60.5 ng/mL, 148.5+/-78.7 ng/mL). At the cutoff value of 100 ng/mL for hyaluronic acid and 200 ng/mL for type IV collagen, the sensitivities were 66.7% and 55.6%, and specifities were 82.9% and 89%, and diagnostic efficiencies were 78.9% and 80.7% respectively for discriminating patients with cirrhosis (4 points) from the mild to severe fibrosis (0~3 points). CONCLUSIONS: The serum levels of hyaluronic acid and type IV collagen may be sensitive markers of fibrotic process in chronic liver diseases and useful biochemical markers in differentiation of the patients with early cirrhosis from those with chronic liver diseases.

Intimal hyperplasia, an abnormal migration and proliferation of vascular smooth muscle cells with associated deposition of extracellular connective tissue matrix, is a chronic structual changes occuring in denuded arteries, arterialized vein and prosthetic bypass graft. This is one of the most important cause of vascular graft failure within the first year after operation. Certain growth factors, particularly basic fibroblast growth factor, transforming growth factor- , and platelet-derived growth factor, are believed to be the cause of the smooth muscle cell proliferation and migration. This smooth muscle cell proliferation and collagen deposition eventually produce intimal thickening with subsequent stenosis or occlusion of the vascular lumen. In order to evaluate the serial changes of injured vessel wall, aortic patch allograft was done in rat, and studied the morphological finding at 1 day, 1, 2, 6, and 8 weeks after graft. The results were summerized as follows; (1) During the early phase after graft, no significant wall changes were seen in the region of the anastomotic site except the presence of acute inflammatory cells with platelet aggregation and thrombus formation. (2) The intimal thickening was apparent by 1 week and was predominantly composed of smooth muscle cells. At the 2 weeks after graft, endothelial cells were partially regenerated to cover the patch graft, and intimal hyperplasia was composed of a mixture of smooth muscle cells and extracellular matrix, mostly collagen. (3) Six weeks after graft, prominent features were production and deposition of collagen rather than proliferation of smooth muscle cells. Reendothelialization over the thickened intima was seen at 8 weeks and the propagation of intimal hyperplasia to adjacent intima of normal vessel was also noted. In conclusion, intimal hyperplasia after vascular injury seemed to be a progressive response of the proliferation and migration of smooth muscle cells and this result might be used for further study about the suppression of intimal hyperplasia.

370 eyes which underwent phtorefractive keratectorny With VISX 20/20 excuner laser were evaluated. At 6 months post-op, the low myopic group(under -6D) of 172 eyes with mean pre-op refractive error of -4.48D changed to -0.54D, the moderate myopic group(between -6D and -9D) of 128 eyes changed from -7.47D to -1.19, and the hlgh myopic group(above -9D) of 70 eyes changed from -11.29D to -2.68D, 76%, 61.9%, ahd 17.4% of the respective groups were with +/-1D of emmetropia. Uncorrected vision hetter than 20/40 was achiced in 90.7%, 75.2% and 31 9% of the resperective groups. The best corrected vision below 2 lines from the best pre-op level was seen in 1.2%, 2.3%, and 4.3% of the respective groups. The astigmatic correction rate was 6.6% in the eyes under 1D of astigmatism, 36.1% in the eyes between 1D and 2D, and 54.5% in the eyes more than 2D.
