Inositol 1,4,5-triphosphate(InsP,) is a second messenger for obilizing intracellular Cal'. It can be dephosphorylated by soluble and particulate forms on InsP, 5-phosphatase, or phosphorylated to produce inositol 1,3,4,5-tetrakisphosphate(InsP,) by InsP, 3-kinase. These enzymes represent possible targets for the regulation of the InsP,AnsP. signal. InsP, 3-kinase which catalyses th ATP-dependent phosphorylation of InsP, was purified from bovine brain tissue. All operation were carried out at 41C. Fresh tissure was homogenized and centrifuged. The supernatant was pooled. Proteins were precipitated from 10% polyethylene glycol, and suspended solution was applied to DEAE cellulose column for chromatography. As the result of above procedure, two isozymes of InsP, 3-kinase, I and U were obtained. Each isozyme was applied to Matriz green gel, Calmodulin-Affigel 15 column and subsequent phenyl-TSK HPLC column. Specific activites(SA) and fold of puriety were observed at each purification step of chromatography. At DEAE cellulose chromatography, SA were 1, 0.6 and 11, 4.8 nM/min/mg, and folds

STUDY DESIGNS: A retrospective study. OBJECTIVES: To analyze the clinical and radiological outcomes of spontaneous reduction via minimally invasive transforaminal lumbar interbody fusion (Mini-TLIF) as the treatment for low-grade symptomatic spondylolisthesis. SUMMARY OF LITERATURE REVIEW: Although minimally invasive transforaminal lumbar interbody fusion is technically demanding, this procedure is an effective method for spontaneous reduction of low grade spondylolisthesis. MATERIALS AND METHODS: We analyzed consecutive series of 41 patients with low grade spondylolisthesis who underwent minimally invasive transforaminal lumbar interbody fusion, between April 2008 and July 2009. The minimum follow-up period was 2 years. Clinical evaluation was performed by an analysis of Visual Analogue Scale and Oswestry Disability Index. For the radiological evaluation, disc space height, slip percentage, and slip angle were analyzed. At the final follow-up, the fusion rate was analyzed according to the Bridwell's anterior fusion grade. RESULTS: For the evaluation of clinical outcomes, the Visual Analogue Scale for back pain decreased from 6.8+/-1.2 to 2.0+/-1.1, and that for radiating pain decreased from 7.9+/-1.3 to 1.7+/-1.1. Oswetry Disability Index decreased from 38.5+/-8.4 to 13.4+/-6.1. For the radiological evaluation, disc space height increased from 8.4+/-2.14mm to 11.8+/-1.54mm(P<0.05), slip percentage was reduced from 18.4+/-5.1% to 13.3+/-3.1%(P<0.05) and slip angle decreased from 10.6+/-4.5degrees to 6.2+/-3.4degrees (P<0.05). At the final follow-up, radiological union was obtained in 38 cases (92.7%). CONCLUSIONS: We conclude that minimally invasive transforaminal lumbar interbody fusion appears to be an effective method for spontaneous reduction of low grade spondylolisthesis if the surgeon becomes familiar with this method.

Sex cord-stromal tumors of the ovary are the third most common types of neoplasms that develop in the ovary and account for about 5-8% of all ovarian malignancies. This group of ovarian neoplasms is derived from the sex cords and the ovarian stroma or mesenchyme. Granulosa-stromal cell tumors include granulosa cell tumor, thecoma and fibroma. The granulosa cell tumor is a low-grade malignancy and accounts for about 2-3% of all ovarian malignancies. Granulosa cell tumors have a prolonged natural history and tendency toward late relapse, reflecting their low grade biology. We present a case of juvenile granulosa cell tumor of the ovary with brief review of literature,

In order to prevent cross-infection, the sterilization of used and/or contaminated anesthetic- apparatus is still a difficult problem in clinical practice, particularly, following anesthesia for known advanced pulmonary tuberculosis cases. Therefore the antibacterisl activities of, an amphoteric detergent, Dodecyl diaminoethyl glycin hydrochloride (Hygien 51) were tested in vitro as a disinfectant against mycobacteria (M. tuberculosis H37 Rv, M. bovis, M. avium, M. tuberculosis H37 Ra, M. phlei, B.C.G.) The antimycobacterial activity tests were performed according to the modified Kolmer method. The testing organisms were cultured in Dubos broth at 37 degrees C, and the detergent, Hygien 51, was: diluted with sterile distilled water to 1,3,5 and 10%. One half milliliter of culture was pipetted into each tube containing 4.5 ml of diluted detergent, and at intervals of 3, 15, 30, 60, 120, 180 and 240 minutes, a 4mm loopful of the material was removed from each tube, and transferred to Ogawa media. The tests were carried out at two different temperatures, 20 degrees C and 50 degrees C. The subcultures were incubated at 37 degrees C for more than 8 weeks. The results were obtained as follows: 1) At room temperature (20 degrees C), all mycobateria, except M. bovis, were destroyed by treatment- with 10% solution of the detergent for more than 60 minutes. M. bovis was relatively sensitive to the detergent, and was killed by 5% solution for 30 min. and 10% for 15 min., but M. avium. was very resistant, and was not killed by 10% solution for 240 min. 2) By treatment with the detergent at 50 degrees C, the antimycobacterial activities of the detergent were highly increased. All mycobacteria were destroyed by 1% solution for 180 min, and by 10% for less than 30 min at 50 degrees C. In the comparison of the antibacterial activities against mycobacteria and other bacteria, it shows that mycobacteria are generally more resistant to the detergent, Hygien 51.

OBJECTIVES: To isolate and culture of human muscle cells by manipulating culture conditions. METHODS: Muscle samples were obtained during total hip replacement or bedside muscle biopsy. We isolated myoblasts from freshly obtained human muscle tissue by trypsin and collagenase digesion. RESULTS: Selective isolation of myoblasts was identified through histologic examination by light-microscope. We identified monoc]onal antibodies(Leu-19) as molecular markers in human skeletal muscle were expressed. CONCLUSIONS: This study demonstrated that it had been possible to culture morphologically and immunelogically identifiable myoblasts isolated from human skeletal muscle tissue.

PURPOSE: To compare clinical outcomes of various surgical methods of intraocular lens dislocation correction surgery. METHODS: We retrospectively analyzed the medical records of patients who underwent intraocular lens dislocation correction surgery with and without vitrectomy by two seasoned surgeons, and compared postoperative best corrected visual acuity and spherical equivalent. Clinical outcomes of secondary intraocular lens insertion after primary intraocular lens removal and primary intraocular lens reposition were compared among the cases without vitrectomy. RESULTS: Dislocated intraocular lens correction without vitrectomy showed better postoperative visual acuity compared to procedures with vitrectomy (0.35 +/- 0.37 vs. 0.54 +/- 0.18; t-test, p = 0.001), but there were no significant differences in spherical equivalent (1.30 +/- 1.10 vs. 1.80 +/- 1.57; p = 0.24) between cases with and without vitrectomy. In comparing primary intraocular lens reposition and secondary intraocular lens insertion among the cases without vitrectomy, the outcomes did not show significant differences in best corrected visual acuity (0.28 +/- 0.40 vs. 0.40 +/- 0.37; p = 0.38) or spherical equivalent (1.66 +/- 1.43 vs. 1.07 +/- 0.79; p = 0.19). In comparing secondary intraocular lens insertion into the capsular bag and fixation to the sclera, iris and iris sulcus, the outcomes did not show significant differences in best corrected visual acuity (p = 0.49) or spherical equivalent (p = 0.33). CONCLUSIONS: The various intraocular lens correction methods examined did not show clinically significant differences in best corrected visual acuity and spherical equivalent when performed by experienced surgeons, except for better postoperative best corrected visual acuity in cases without vitrectomy compared to cases with vitrectomy.

PURPOSE: Metabolic syndrome (MS) plays a potential role in the etiology of benign prostatic hyperplasia (BPH). Recent studies have reported on an association between MS and BPH. However, there has been no consensus on recent results. This study was conducted to evaluate the associations among prostate-specific antigen (PSA), prostate volume (PV), and metabolic components in men who visited our health promotion center. MATERIALS AND METHODS: During the period from January 2005 to December 2010, 521 consecutive men (age range, 40 to 70 years) who underwent transrectal ultrasonography were enrolled in this retrospective study. The health screening program includes blood pressure, body measurements (height, weight, waist circumference, body mass index), biochemical analysis (serum glucose, total cholesterol, triglycerides, high-density and low-density lipoprotein cholesterol, fasting plasma glucose, tumor markers), stool and urine analysis, and a detailed clinical examination. RESULTS: The serum PSA level and PV were significantly higher in patients with MS than in patients without MS, retrospectively (p<0.001, p<0.001). Patients with more than one metabolic component were significantly more likely to have a larger PV and higher serum PSA level. The serum PSA level and PV were increased in a similar manner with the increasing sum of MS components (p<0.0001, p<0.0001). CONCLUSIONS: The MS components were associated with larger PV and higher serum PSA level. Therefore, each MS component could be an important factor in BPH development and management.

PURPOSE: To assess changes in lower urinary tract symptoms (LUTS), prostate volume, and serum prostate-specific antigen (PSA) after discontinuation of 5-alpha reductase inhibitor (5ARI) combination therapy in patients with benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: From December 2003 to December 2012, data were collected retrospectively from 81 men more than 40 years of age with moderate to severe BPH symptoms (International Prostate Symptom Score [IPSS]> or =8). The men were classified into group 1 (n=42) and group 2 (n=39) according to the use of 5ARI therapy. A combination of dutasteride 0.5 mg with tamsulosin 0.2 mg was given daily to all patients for 1 year. For the next 1 year, group 1 (n=42) received the combination therapy and group 2 (n=39) received tamsulosin 0.2 mg monotherapy only. The IPSS, prostate volume, and PSA level were measured at baseline and at 12 and 24 months according to the use of dutasteride. RESULTS: Discontinuation of dutasteride led to significant deterioration of LUTS, increased prostate volume, and increased PSA level. The repeated-measures analysis of variance showed that the changes in IPSS, prostate volume, and PSA level over time also differed significantly between groups 1 and 2 (p<0.001). CONCLUSIONS: Withdrawal of 5ARI during combination therapy resulted in prostate regrowth and deterioration of LUTS. The PSA level is also affected by the use of 5ARI. Therefore, regular check-up of the IPSS and PSA level may be helpful for all patients who either continue or discontinue the use of 5ARI.
