In the 88 cases of biliary disease, which was proven in Seoul Red Cross Hospital from Jan. 1980 to Dec. 1981,comparative studies were made with oral and IV cholecystocholangiographic findings and ultrasonographic findings.The resuslts were ; 1. In the 18 cases of GB stones, there are 17 cases (94.4%) of positive findings incholecysto-cholangiography with detection of stone in 7 cases (38.9%), while in sonographic study, 16 cases(88.9%) are shown positive findings with detection of stones in 11 cases (61.1%). 2. In the 17 cases of acalculouscholecystitis, the diagnostic accuracy is 88.2% in cholecystocholangiography and 64.7% in sonography. 3. In the 7cases of CBD stones, all cases are shown positive findings in cholecystocholangiography with detection of stone inonly one case (14.3%), while 6 cases (85.7%) of positive findings are shown in sonography with detection stone inall cases. 4. I.V. cholanagiography is more accurate diagnsotic procedure rather than oral GB study in the casesof poor or non-functioning GB. 5. Sonography is the choice of procedure in the diagnosis of stones, while in thecases of colecystitis, cholecystocholangiography is more useful diagnostic procedure.

Glucocorticoids are usually given according to a standard dosing protocol regardless of individual difference. We evaluated the pharmacokinetic characteristics of methylprednisolone and the degree of interpatient variation in stable Korean renal transplant recipients during the period of 15-21 days after transplantation. This study included 23 renal transplant recipients, 13 males and 10 females, who received kidneys from living donors with stable graft function and without episode of acute rejection. On the study day at 8 A.M., 16.3mg of ethylprednisolone sodium succinate (i.v.) was administered to each patient instead of usual dose (20mg) of prednisolone (p.o.) after sampling of 7cc of baseline blood and additional blood samples were drawn after starting infusion. Plasma was separated and analyzed for methylprednisolone level using high performance liquid chromatography (HPLC) assay, and parameters for pharmacokinetics were calculated. There was significant interpatient variation in the pharmacokinetics of methylprednisolone in our patients group. There was no significant difference in the pharmacokinetic parameters between patients with and without side effects of steroid. Korean renal transplant recipients had higher volume of distribution than black renal transplant recipients; lower clearance than white renal transplant recipients; longer t1/2 than both black and white renal transplant recipients. Even if the number of patients included in this study was too small to reach conclusion, the differences in the pharmacokinetics of glucocorticoids do not seem to be a significant risk factor for side effects of steroid after transplantation. It may be necessary to individualize the dose of a glucocorticoid to achieve an optimal effect and also we need to establish a new steroid regimen protocol for Korean renal transplant recipients.

OBJECTIVE: To analyze the biomechanics of young patients with flat foot or malalignment syndrome of lower extremities and to provide some information and strategies in examining and treating them for other researchers or successive studies. METHOD: Between January 2004 and March 2006, 274 patients were engaged who had been diagnosed as flatfoot in 586 patients aged between 0 and 18. All patients were examined physically by one physiatrist to find other biomechanic abnormalities of lower extremities and to measure resting calcaneal stance position (RCSP) angle, bimalleolar angle (BMA). To detect the existence of scoliosis and the difference in leg length, radiographs were taken of the spine and the lower extremities. Flat foot was defined as when either of the feet had lower than -4degrees degrees of RCSP angle. RESULTS: When comparing the value of RCSP angle between right side and left side, the left side was more pronated than the right side. The value of RCSP angle increased in proportion to age but there are other factors that caused the persistence of foot pronation and ligament laxity. The value of BMA tends to increase in proportion to age. The foot was more pronated, the tibia of the same side was more rotated internally and tibia of the other side was more rotated externally. The most common combined biomechanic abnormality of lower extremities was toe-in gait. CONCLUSION: Because the biomechanic effect of a foot could influence the leg, pelvis of the same side and the other side lower extremity, the flat foot should be regarded as an element of malalignment syndrome, anatomical abnormality, and also functional impairment.

OBJECTIVE: To investigate the disability identity and life satisfaction according to the severity of disability in the spinal cord injured persons resident in the community. METHOD: The subjects of this national wide study were 397 spinal cord injured persons resident in the community. We investigated their disability identity, life satisfaction, depression, social integration and social support. The questionnaire included the newly developed disability identity scale to evaluate the disability identity, that consisted of five sub-scales (personal worth, self-acceptance with the disabled, individual civil right, common cause and external barriers) and 23 questions. The subjects were divided into four groups according to severity of disability: motor complete tetraplegia, motor incomplete tetraplegia, motor complete paraplegia and motor incomplete paraplegia. RESULTS: The scores of life satisfaction, depression and social support were not different according the four groups. However the disability identity scale of the motor incomplete paraplegia was lower than motor complete tetraplegia or motor complete paraplegia (p<0.05). The sub-scale score of the personal worth and self-acceptance were lower in less severely disabled persons. As the disability identity scale was higher, social integration (r=0.478, p=0.000), and social support (r=0.465, p=0.000) were moderate and the depression was negative (r=-0.252, p=0.000). Conclusion: Less severely disabled persons showed lower disability identity. Disability identity scale was significantly correlated with higher social integration, higher social support and lower depression score. The newly developed disability identity scale will be a useful tool for the evaluation of the psychological status and planning the rehabilitation strategy for spinal cord injured persons.

Painful legs and moving toes syndrome (PLMT) is a rare syndrome characterized by pain in the lower extremities and involuntary movements of single or multiple toes. A 29-year-old woman with lumbosacral intervertebral disc herniation complained of bilateral foot pain and involuntary toe movements for three months. This is the first case of PLMT in a young adult patient with a lumbosacral intervertebral disc herniation in Korea.

PURPOSE: To evaluate the preference factors for the treatment of erectile dysfunction (ED) with three different kinds of PDE-5 inhibitors. MATERIALS AND METHODS: This prospective, open-label study recruited 140 patients from 5 medical centers and urological clinics in the Daegu and Gyeongbuk area of South Korea. All patients underwent sildenafil, tadalafil, and vardenafil therapy with at least four attempts at sexual intercourse for each medication. There was a 1-week drug washout period following each medication period. Patients were asked to state their preference among the three medications. RESULTS: The mean age of the 140 patients was 50.9 years. Most patients had mild-to-moderate ED(57 patients, 40.7%) and moderate ED(47 patients, 33.6%), the remaining patients had mild(23 patients, 16.4%) or severe ED (13 patients, 9.3%). Of 140 evaluated patients, 58(41.3%) patients preferred treatment with tadalafil, compared with 39(28.1%) with sildenafil and 37(26.6%) with vardenafil. When grouped by age, tadalafil was most preferred by men in their 30s and 40s(42.9%, 57.5%), sildenafil was preferred by those in their 50s(48.3%), and vardenafil was preferred by those in their 60s(51.6%). The reasons for specific preferences were prolonged erectile function (68.0%) and good erectile function(66.0%) for tadalafil, good erectile function (88.2%) for the sildenafil, and good rigidity of the erect penis(59.4%) for vardenafil. CONCLUSIONS: Tadalafil was most preferred among the phosphodiesterase inhibitors, but the preference rates varied for men of different ages. All the medications were well tolerated.

BACKGROUNDS: Peripheral blood stem cells (PBSC) are increasingly used because of ease of collection and rapid kinetics of recovery relative to bone marrow transplantation (BMT). Here we summarize laboratory and clinical experiences of 671 PBSC harvests performed at a single institution. METHODS: PBSC harvests were performed mainly with Fenwal CS3000 plus blood cell separator. 126 cancer patients and 12 allogeneic BMT donors (54 children, 84 adults) were enrolled in this study. Total WBC and mononuclear cells (MNC) were analyzed in peripheral blood before procedure, and total WBC, MNC and CD34+ cell count on PBSC product. Correlation between dose of CD34+ cells and hematologic recovery was evaluated by Wilcoxon rank sum test and Pearson correlation analysis. RESLUTS: A mean of 4.8 leukapheresis was performed and 9,155 mL blood was processed. A mean volume of PBSC product was 66 mL and MNC purity of that was 84%. An average of 3.0 +/- 3.3x108 WBC/kg, 2.4 +/- 2.6x108 MNC/kg, and 2.7 +/- 5.4x106 CD34+ cells/kg was collected in each procedure. A goal of 1x108/kg MNCs was reached in 98.4% (127/129) of the patients and more than 1x106/kg CD34+ cells were collected in 91.8% (90/98). Various complications of PBSC harvests were observed but the incidence of serious adverse reaction was low. Median times to an absolute neutrophil count over 500/uL were 11 (7-34) and 11 (8-29) days respectively, in adult and children, and those to a sustained platelet count over 50,000/uL were 18.5 (9-118) and 36 (16-85) days, respectively. CONCLUSION: We analyzed yield, adverse reaction and hematologic recovery of PBSC harvests and this can serve basic data for the PBSC procedure.

Purpose: In this study, we investigated the effect of bisphenol-A (BPA) and its major analogs, bisphenol-F (BPF), and bisphenol-S (BPS), on spermatogonial stem cells (SSCs) populations using in vitro SSC culture and in vivo transplantation models. Materials and Methods: SSCs enriched from 6- to 8-day-old C57BL/6-eGFP+ male mice testes were treated with varying concentrations of bisphenols for 7 days to examine bisphenol-derived cytotoxicity and changes in SSC characteristics. We utilized flow cytometry, immunocytochemistry, real-time quantitative reverse transcription-PCR, and western blot analysis. The functional alteration of SSCs was further investigated by examining donor SSC-derived spermatogenesis evaluation through in vivo transplantation and subsequent testis analysis. Results: BPF exhibited a similar inhibitory effect on SSCs as BPA, demonstrating a significant decrease in SSC survival, inhibition of proliferation, and induction of apoptosis. On the other hand, while BPS was comparatively weaker than BPA and BPF, it still showed significant SSC cytotoxicity. Importantly, SSCs exposed to BPA, BPF, and BPS exhibited a significant reduction in donor SSC-derived germ cell colonies per total number of cultured cells, indicating that, like BPA, BPF, and BPS can induce a comparable reduction in functional SSCs in the recipient animals. However, the progress of spermatogenesis, as evidenced by histochemistry and the expressions of PCNA and SSC specific markers, collectively indicates that BPA, BPF, and BPS may not adversely affect the spermatogenesis. Conclusions Our findings indicate that the major BPA substitutes, BPF and BPS, have significant cytotoxic effects on SSCs, similar to BPA. These effects may lead to a reduction in the functional self-renewal stem cell population and potential impacts on male fertility.
