STUDY DESIGN: Changes of morphology and phenotype of cultured cells in media added lactate were observed. OBJECTIVES: To evaluate the effect of lactate on morphology and phenotype of cultured intervertebral disc cell. SUMMARY OF LITERATURE REVIEW: It was reported that lactate and pH were important factor in the degeneration of intervertebral disc. However the effect of lactate on morphology and phenotype of cultured intervertebral disc cell have not been studied. MATERIALS AND METHODS: Cells were dissociated enzymatically from rabbit nucleus pulposus. After attaining monolayer growth, the cells were incubated in media added 2mM or 5mM lactate. Total cell counts and morphological changes of the cells were periodically observed. Changes in cell phenotype were investigated by use of anti-collagen antibody stain. RESULTS: The cell groups added no lactate and 2mM lactate showed no difference in cell counts, morphology and phenotype. The cell group added 5mM lactate showed a reduction in final cell Counts and highel'ratio of fibroblastic cell in total population. Anti-collagen I Ab stained the Intra-and extra-cellular area of fibroblastic cells and intracellular area of chondrocytic cells. CONCLUSIONS: The current study suggests that high concentration of lactate inhibit intervertebral disc cell proliferation and accelerate morphological and phenotypical change to fibroblastic cell.

The development of tophi in th absence of prior episodes of gauty arthritis is unusual. We report a case of extensive tophi in a 31 year-old man, whose initial skin lesion had started without arthritis.

Myopic discs(range: -0.5D) which were taken a confocal scanning laser ophthalmoscope(HRT, Heidelberg Engineering) were analyzed to determine the relationship between optic disc parameters and myopic refractive errors. Regression analysis and coefficient variation were used for a statistic tool. The disc area was not correlated with the myopic refractive error(p=0.21) and showed 16.0% of coefficient of variation. Cup area, cup disc area ratio, rim area, cup volume, rim volume, mean cup depth, maximum cup depth and cup shape measure showed statistically significant correlation with myopic refractive error, respectively(p<0.05). Among these parameters, rim area varied least(within all myopic eyes) with 16.5% of coefficient of variation. As the rim area is the most stable optic disc parameter interindividually in myopic population, it seem to be valuable for follow-up evaluation when a glaucomatous damage is suspected in myopic eyes by calculating its expected normal value with a regression equation.

PURPOSE: Kawasaki disease is notorious for coronary arterial complication which is usually developed as a febrile disease in early childhood. Increased polymorphonucleus(PMN) cell levels in acute phases may be associated with the pathophysiology of Kawasaki disease. We studied the relationship between coronary arterial dilatation and elastase activity which was excreted from PMN cell and roles as an important factor for vasculitis. METHODS: Ten patients diagnosed with Kawasaki disease in Yonsei University Medical Center were examined between November, 2001 and January, 2002. In addition, 15 patients with other febrile diseases were also examined. Echocardiography was done in patients with Kawasaki disease on the first day of admission and four weeks after the onset of the disease. At each time, venous samples were drawn and separated into plasma and leukocytes. In patients with other febrile disease, samples were drawn on admission. Elastase activities in plasma and neutrophil extracts were measured. RESULTS: The significant increased plasma elastase activity, 6.19+/-0.74 U/mL, found in Kawasaki disease patients compared with the other febrile disease patients, 4.86+/-1.17 U/mL(P<0.05). And there was no significance between the above two diseases in terms of the elastase activity in neutrophil extracts. The relationship between initial elastase activity and the coronary arterial complication which was shown in subacute phase wasn't significant. CONCLUSION: Plasma elastase activity was increased in Kawasaki disease significantly, but the initial plasma elastase activity in the acute phase could not reflect the range of coronary arterial complication.
