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.

PURPOSE: In the diagnosis of pediatric urinary tract infection(UTI), the use of invasive methods, such as voiding cystourethrography(VCUG), is controversial. A retrospective study was carried out to evaluate the necessity for VCUG in assessing pediatric UTI. MATERIALS AND METHODS: Between April 2000 and March 2002, 70 children (60 boys, 10 girls) with symptomatic UTI were evaluated. All patients were evaluated with renal ultrasonography(RUS), 99mTc-DMSA renal scintigraphy(DMSA renal scan) and VCUG. The results of the VCUG were compared with RUS and similar comparisons made between the results of the VCUG and DMSA renal scans. Patients with both normal a RUS and DMSA renal scan were then evaluated for the frequency and grade of vesicoureteral reflux(VUR) on the VCUG. RESULTS: The mean age at the initial evaluation was 7.95 months, ranging from 1 to 52 months. RUS and DMSA scan abnormalities were found in 38(54.3%) and 26(37.1%) children, respectively. Of the 22 patients with VUR confirmed by VCUG, 11(50.0%) had an abnormal RUS, and 12 (54.5%) patients had abnormal DMSA renal scans. Of the 19 patients with both a normal RUS and DMSA scan, 4(21.2%, 6 kidney-ureter unit) were found to have VUR on VCUG. CONCLUSIONS: This study illustrated that a considerable number of patients may have significant VUR, despite normal renal ultrasonography and DMSA scans. Therefore, VCUG remains important in assessing pediatric UTI.

BACKGROUND: The effectiveness for vagal stimulation by ice water aplication to face during metronome-controlled respiration of 15 breaths/minute was examed. The importance of basal vagal tone and sympathovagal interaction in the individual variability of responsiveness to the vagal stimulation was investigated. METHOD: Fifty three 12~13 year old healthy volunteers were included. Vagal tone and sympathovagal interaction before and after application of ice water to the face were assessed by power spectral analysis of RR interval(heart rate) variability. RESULT: Basal heart rate, high frequency power, and low to high frequency power ratio were 81+/-13(58~110 beats/min), 791+/-1061(56~4161 msec2) and 1.08+/-1.22(0.04~4.85) during controlled respiration. After ice water application twenty three children developed 5 more nodal escape beats due to severe bradycardia. Minimum heart rate, high frequency power and low to high power ratio changed to 42+/-12(19~72/min), 1890+/-1882(221~7258msec2) and 0.64+/-0.43(0.12~1.46). The increased ratio of high frequency power, maximum heart rate decrement and its percent after stimulation were 5.44+/-5.62(0.63~24.26), 39+/-14(10~81/min) and 47+/-15(16~81%) respectively. The increased ratio of high frequency power was correlated with basal logarithmic high frequency power(r=-0.60, p=0.0004). Maximum heart rate decrement was correlated with basal logarithmic high frequency power(r=-0.41, p=0.0018) and low to high frequency power ratio(r=0.27, p=0.04). CONCLUSION: Application of ice water to the face during controlled respiration produces powerful vagal stimulation and bradycardia, however, there is a wide individual variability of responsiveness to it. The absolute basal vagal tone contribute to this individual variability.
