PURPOSE: A retrospective study on the usefulness of selective spinal nerve root block among lumbar herniated intervertebral disc (HIVD), spinal stenosis and postoperative syndrome over 10 years. MATERIAL AND METHOD: From a total 1195 patients, whose symptoms were not improved by conservative treatment, 505 treated by selective nerve root block were divided into 3 groups; 150 (29.7%) with HIVD, 313 (62.0%) with spinal stenosis and 42 with postoperative syndrome, and were followed up from Oct. 1992 to Dec 2001. The degree of pain and activity were evaluated by a visual analogue scale method at the out-patient department or through telephone interviews. RESULTS: The end-results of selective spinal nerve root block, with more than 50% reduction in pain occurred in 380 (75.3%) of the 505 patients. The effectiveness was greater in young patients with HIVD than elderly patients with spinal stenosis. After discharge, 160 patients (31.7%) needed no other treatment: 14 (31.0%) with an extrusion type HIVD and 17 (20.0%) with spondylolisthesis. The only 98 patients (19.4%) needed a surgical procedure after selective spinal nerve root block. CONCLUSION: Selective spinal nerve root block in patients with lower back and radiating pain is a valuable conservative treatment to quickly improved symptoms and avoid surgical procedures and the continuous administration of drugs.

BACKGROUND: Rescently, the immunotherapy against infectious disease and cancer is being actively studied, and high yield of pure CD14+ monocytes is a key of concern. In this study, we optimized the percoll gradient method to increase the purity and yield of monocytes from peripheral mononuclear cells. METHODS: We separated mononuclear cells (MNC) from healthy donors, and monocytes from MNC were separated with the various density of percoll gradient. After centrifugation, we determined the most efficient density of the percoll gradient to get the highest yield and purity of monocytes. We also obtained monocytes by the plastic absorption method. Monocytes were differentiated into dendritic cells (DC) and the efficacy of differentiation to DC is confirmed and compared by morphological characteristics and using a flowcytometer. RESULTS: The purity of monocytes was 51.3+/-8.3% by the 35% percoll gradient method and the purity was improved to 82.9+/-4.2% with 100% of yield by repeating the same method. Therefore, the yield of mature dendritic cells was 3.6+/-0.9% of the total input MNC by the 35% percoll repetition method, which was 1.7 times higher than the plastic adherent method (2.1+/-0.5%). CONCLUSION: This study shows a cost-effective method to isolate CD14+ monocytes and these cells demonstrate high differentiation rate to DC. This process will be valuable for obtaining a sufficient number of DC.

This study was carried to determine the possibility of finding motile spermatozoa and fertilization, pregnancy rate after testicular sperm extraction(TESE) with ICSI in obstructive and non-obstructive azoospermic patients. In 154 cases(132 patients), obstructive azoospermia was 77 cases and non-obstructive azoospermia was 77 cases. In obstructive azoospermia, patients generally showed normal spermatogenesis and included vas agenesis(n=8), multiple vas obstruction(n=7), epididymal obstruction (n=54). Total of 982 retrieved oocytes were obtained and 84.4% were injected. The fertilization rates with 2 PN and cleavage rate were 72.5% and 62.3%, .respectively. 30 pregnancies(38.9%) were achieved and the ongoing pregnancies were 22 cases (28.6%). In non-obstructive azoospermia, patients showed hypospermatogenesis(n=49), maturation arrest(n=4), Sertoli cell only syndrome (n=24). The various stages of spermatogenic cell could be retrieved by TESE and could be reached normal fertilization and embryo development with ICSI. Total of 1072 retrieved oocytes obtained and 80.2% were injected. The fertilization rates with 2 PN and cleavage rate were 52.8% and 68.9%, respectively. 22 pregnancies(30.1%) were achieved and the ongoing pregnancies were 19 cases(26.0%). Conclusively, the combination of TESE with ICSI using testicular spermatozoa can achieve normal fertilization and pregnancy rate and effective method in obstructive and non-obstructive azoospermic patients.

Irreparable obstructive azoospermic patients can be treated successfully with microsurgical epididymal sperm aspiration(MESA) o. testicular sperm extraction (TESE) by intracytoplasmic sperm injection(ICSI). Obstructive azoospermic patients generally have normal spermatogenesis. The aim of this study was to see if any spermatozoa could be retrieved from non-obstructive azoospermia and to assess the efficacy of ICSI with TESE in germinal failure. 42 non-obstructive azoospermic patients revealed no spermatozoa at all in their ejaculates, even after centrifuge. The histology of 42 patients revealed 15 Sertoli cell only Syndrome, 4 maturation arrest and 23 severe hypospermatogenesis. All patients underwent extensive multiple testicular biopsy for sperm retrieval. These patients were scheduled for ICSI using testicular spermatozoa. In 25 out of 42 non-obstructive azoospermic patients, spermatozoa were recovered from multiple testicular biopsy specimen and 11 ongoing pregnancies were achieved. There are usually some tiny foci of spermatogenesis which allow TESE with ICSI in non-obstructive azoospermia. Also these patients may have sufficient sperm in the testes for ICSI, despite extremely high FSH level and small testes.

This study was performed in order to identify changes of the plasma membrane proteins in rat submandibular gland tumors induced by 7,12-dimethylbenz[a]anthracene [DMBA] and X-irradiation. Two kinds of tumor associated membrane proteins (protein A and B) were isolated with 3 M KCl extraction from rat submandibular gland tumors induced by DMBA and X-irradiation. To identify their antigenicities, immunoelectrophoresis and double immunodiffusion was carried out with various proteins extracted from liver, heart, skin and pancreas of adult rats and from embryonic liver, heart and skin. The rabbit antisera against the protein A did not cross-react with any of the proteins extracted from the above mentioned tissues, suggesting that protein A might be tumor specific antigen. However, the rabbit antisera against protein B was precipitated with proteins extracted from the liver of adult and embryonic rats. Polyacrylamide gel electrophoresis of these two proteins (A and B) showed that protein A was a dimer with molecular weights of 69,000 and 35,000 dalton, whereas protein B was a monomer with molecular weight of 50,000 dalton.

BACKGROUND: Chronic kidney disease has deleterious influences on pregnancy, both fetus and mother. To determine the pregnancy outcome and associated risk factors, we analyzed 36 pregnancies in 26 women with various chronic kidney diseases. METHODS: Retrospective analysis of 36 pregnancies was performed in women with chronic kidney disease who underwent antenatal care and delivery at Pusan National University Hospital from January 1993 to December 2002. RESULTS: The mean age of patients was 29.7 +/- 3.6 years. Underlying kidney disease was lupus nephritis in 10 patients (11 pregnancies), IgA nephropathy in 7 patients (8 pregnancies), focal segmental glomerulosclerosis in 4 patients (9 pregnancies), membranoproliferative glomerulonephritis in 4 patients (7 pregnancies), membranous glomerulonephritis in 1 patient (1 pregnancy). Of the 36 pregnancies, fetal loss occurred in 14 pregnancies (38.9%), premature delivery 7 pregnancies (19.4%) and normal delivery 15 pregnancies (41.7%). Deterioration of maternal renal function occurred in 10 pregnancies (27.8%), hypertension 18 pregnancies (50.0%) and aggravation of proteinuria 26 pregnancies (72.2%). Fetal loss and deterioration of maternal renal function were more frequent in patients with preconception serum creatinine value (SCr) >or=1.4 mg/dL than in those with SCr <1.4 mg/dL (85.7% vs. 27.6%, p<0.05; 100% vs. 10.3%, p<0.05, respectively). Neither fetal loss nor deterioration of maternal renal function was associated with hypertension and aggravation of proteinuria. In multivariate analysis, preconception SCr was associated with fetal loss (p=0.014, OR 32.7, 95% CI 2.0-526.0) and BP >or=140/90 mmHg during pregnancy was associated with low birth weight (p=0.027, OR 0.034, 95% CI 0.002-0.682). Deterioration of maternal renal function during pregnancy was recovered in 40.0%, hypertension was recovered in 50.0% and proteinuria was recovered in 77.8% within 1 year after delivery. CONCLUSION: Preconceptional impairment of maternal renal function and uncontrolled hypertension during pregnancy seem to be an important factors associated with fetal loss and low birth weight, respectively.

Phytophotodermatitis is a condition caused by sequential exposure to photosensitizing substances present in plants followed by ultraviolet light. Several plants (e.g., limes, celery, fig, and wild parsnip) contain furocoumarin compounds (psoralens). It is important for dermatologists to be aware of phytophotodermatitis because it may be misdiagnosed as cellulitis, tinea, or allergic contact dermatitis. We present five patients with a sharply defined erythematous swollen patch with bullae on both feet. They described soaking their feet in a fig leaves decoction to treat their underlying dermatologic diseases. Within 24 hours, all patients had a burning sensation in their feet, and erythema and edema had developed on the feet dorsa with exception of the portion of the skin covered by the sandals. Histopathologic examinations revealed sub-epithelial blisters with intensive epidermal necrosis. Phytophotodermatitis was ultimately diagnosed and, after several days, the patients' skin lesions began to recover upon treatment with systemic and topical corticosteroids. Unfortunately, since there are no studies providing sufficient evidence on the benefits of fig leaves, they should be used with caution.
