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.

BACKGROUND: If the corrections of the cryptorchid testes are delayed, it may lead the patients to suffer loss of testes or fertility. So we purposed to analyze the present status of correction and the causes of delay and tried to emphasize the needs to educate and inform the ideal age for correction. METHODS: Total 363 cryptorchid patients who visited our hospital in 10 years from January 1987 to December 1996 were divided into 3 groups according to their ages at visit as under 2, 3 to 5 and over 6 years groups. We analyzed the operative findings of the 3 groups, compared the ratio of the over 6 group during the half ten years till 1991 to the same ratio after 1992 and also analyzed the causes of delay in 81 patients for whom the causes of delay could be identified in over 6 years group. RESULTS: The age distributions showed 88 patients(24.2%) of under 2 years group, 118 patients(32.5%) of 3 to 5 years group and 157 patients(43.3%) of over 6 years group. When we compare the former 5 years till 1991 to the latter 5 years after 1992, the number of the patients who underwent orchiopexy under the age of 2 were increased from 34 (19.1%) to 54(29.2%) and those over the age of 6 were decreased from 88(49.4%) to 69 (37.3%) but still in higher proportion. The intraoperative findings showed that the rate of atropic or smaller testes than normal size in over 6 years group(128 testes, 73.1%) were higher than those of under 2 years(10 testes, 9.8%) and 3 to 5 years group(28 testes, 20.2 %). The most common causes of delay in over 6 years group was recommendation by relatives or neighbors(36 patients, 48.1%) and the remainders were advices of doctors other than urologists(27 patients, 33.3%), poor economic status(8 patients, 9.9%) and unawareness of the anomaly(7 patients, 8.6%). CONCLUSIONS: To prevent the loss of testicular function or testis itself in patient with cryptorchidism, the early correction should be performed because the recommended age for the correction tends to be decreased. The public information for the recommended age should be provided and also educational programs for the primary physicians are supposed to be performed.

We report a case of 17-year-old female with juvenile onset systemic lupus erythematosus Who developed symptomatic unilateral sacroiliitis. She had neither HLA-DR3 nir B27 antigens. Though sacroiliitis have been reported in mail SLE patient. it has been rarely reported in female patients. The rare coexistence of SLE and sacroiliitis. described in this case. may not be determined soley by genetic factors; sacroiliitis may be just an infrequent manifestation of SLE.

Cutis marmorata telangiectatica congenita(CMTC) is a rare congenital cutaneous vascular anomaly. The major skin findings are persistent, fixed cutis marmorata, telangiectasia, and phlebectasia. In approximately 50 % of patients, the disorder tends to be associated with various con-genital anomalies. We describe in this report a 4-month-old male infant with CMTC. The patient had red or violet marbled patches, telangiectases, and atrophy on the right arm present at birth. During the follow up period of 12 months, there was no change in the cutis marmorata pattern and telangiectases, whereas the atrophy has been less prominent than at the initial visit.

We experienced a case of childhood derrnatomyositis associated with calcinosis universalis in a 3-year-old boy. The skin lesion showed generalized, hard nodules and ulcers, 0, 3-1 cm in cliameter, or the trunk and buttock. The hitopathologic findings revealed patch fat necrosis and calcium deposits in the subcutis.

The Venereal Disease Research Laboratory microflocculation (VDRL) test, especially the quantitative test is well standardized, simple, rapid and, at present, the most widely used non-treponernal test in serodiagnosis and follow up sturly of syphilis. However, the UDRL test result could be influenced by room ternperature, especially in summer and winter in Korea in the abscence of proper air-conditioning and heating. This study was undertaken to evaluate the effect of room temperature on the VDRL test result and to determine the critical temperatures which alter the test result. Eighty six VDRL-reactive serum samples collected at the Soonchunhyang Medical College Hospital and the V.D. Clinic of the Chung-Ku Public Health Center in Seoul during the 7 months periods from September 1982 to March 1983 were used. The results obtained were as follows: The change in the VDRL titer was not obscrved at room temperature of between 18 C and 32 C 2. The VDRL titer became weakly reactive on the same titer or lowered to half titer at room temperature of below 18C. R. The VDRL titer increased two fold at room temperature of above 32C.(countinue..)

BACKGROUND: It is well known that systemic blood pressure oscillates with low(0.04~0.1Hz), mid(0.1~0.15Hz), and high(respiratory) frequency range. But there has been no study about oscillation of pulmonary artery pressure(PAP). METHOD: We measured PAP for 5 minutes in 32 patients of ventricular septal defect and stored them to computer files. Power spectral density curve was obtained. Low, mid, respiratory frequency power were measured by integrating the area within each frequency range below the power density curve. RESULT: The incidence of significant low frequency power(more than 5% of total power) were higher in patients of high PAP and hign Rp/Rs than those of low PAP and Rp/Rs(p<0.01 and p<0.005 respectively). The low frequency power positively correlates with PAP and Rp/Rs(r=0.62, p<0.0005 and r=0.61, p=0.0005 respectively). CONCLUSION: It can be said conclusively that as PAP and pulmonary vascular resistance elevates, the PAP tends to definitively oscillate in low frequency range.

Generalized plane xanthoma is less common and usually involves the eyelids, lateral side of the neck, upper trunk, and extremities. Lesions, however, may appear on any portion of the body. Cutaneous xanthomas may occur in hyperlipidemic and in normolipidemic states. Generalized normolipidemic plane xanthoma is often associated with multiple myeloma, other reticulo-endothelial malignancies and monoclonal gammopathy with unknown significance(MGUS). We wish to report two eases of generalized plane xanthoma associated with IgG monoclonal gammopathy of unknown significance.
