The effectiveness of Sulfobenzylpenicillin in the treatment of urinary tract infection was evaluated in the Department of Urology, Seoul National University Hospital during the period from May to November, 1973. Our clinical study was performed on the 28 patients who visited the outpatients clinic and admitted to the ward. These patients were studied by bacterioscopy with Gram's method of staining. and culture in blood agar plate and chocolate agar plate In this studies. the causative organisms were divided into 8 groups; E. coli (5), coagulase positive staphylococcus (5), pseudomonas (2), Corynebacterium spp. (1), a-hemolytic etreptococcus (2), N. Gonorrheae (10), Proteus (2) and KIebsiella (1). The dosage schedule was 1 gm. of Sulfobenzylpenicillin at intervals of 12 hours for consecutive 5 days in gonococcal urethritis and nongonococcal urethritis. But in upper urinary tract infections and post-operative infections, it lasted for 7 to 10 days or more. And following results were obtained. Effectiveness on Urological diseases 1) Gonococcal urethritis; Satisfactory clinical results were obtained with Sulfobenzylpenicillin for five days. Results were excellent in 5 cases, good in 4 cases and negative effect in 1 case. 2) Non-gonococcal urethritis; In this group, the therapeutic results were favorable in 90% of all cases. (excellent-4, good-5, fail-l) 3) Urethral stricture and fistula (2 cases); AII cases were responded to the Sulbenicillin. 4) Cystitis including Prostatism; Two of three cases were caused by E. coli and they had a good response to sulbenicillin. 5) Two cases of pyelonephritis and two cases of postoperative infections were studied with sulbenicillin and more than 60% of cases were effective with sulbenicillin. Side effects were not remarkable but in a few cases who received intramuscular injection, pain on the injection site was noticed.In summary, this new semi-synthetic penicillin is considered to be a useful chemotherapeutic weapon against a variety of infection in the urological field including those due to Gram negative bacilli such as pseudomonas and proteus sp.

Hypernephroma comprises about 85-90% of renal malignancy in adults. The natural course of hypernephroma isvery diverse and unpredictable from abrupt explosive growth with wide spread metastasis to asymptomatic slowgrowth for several years. Reports from aliens indicated that hypernephroma with histopathological papillary growthpattern has better prognosis and more frequently hypovascular on renal angiography and less echogenic onultrasonography than non-papillary hypernephroma. Reviewed here retrospectively all the patients who were admittedand diagnosed as hypernephroma histopathologically at the Severance Hospital from March, 1973 through September,1984, in respective of angiographic vascularity, ultrasonographic echogenicity, histopathologic cell type andgrowth pattern, and following results were obtained. 1. The incidence of calcification in hypernephroma was 7cases out of 53 cases(13%). The incidence of hypernephroma according to cell type was clear cell type 20 cases(56%), mixed cell type 11 cases (31%), granular cell type 4 cases (11%), sarcomatous cell type 1 case(2%). Theincidence of hypernephroma according to growth pattern was papillary growth pattern 14 cases(45%) andnon-papillary growth pattern 17 cases(55%). 2. Renal angiographically, hypervascular hypernephroma was 19cases(73%), hypovascular hypernephromas was 6 cases(23%), all of which showed abnormal marginal vessels. 3.Angiographically hypervascular hypernephroma had high incidence of predominantly high echogenicity andangiographically hypervascular hypernephroma had high incidence of predominantly low echogenicity. 4. Clear celltype hypernephroma had high incidence of predominantly low echogenicity on ultrasonography. 5. Predominantly lowechogneic hypernephroma had high incidence of papillary growth pattern and predominantly high echogenichypernephroma had high incidence of non-papillary growth pattern. In summary, clear cell type hypernephroma hadhigh incidence of hypovascularity angiographically and hypovascularity on angiography was correlated withpredominantly low echogenicity on ultrasonography, and predominantly low echognicity had high incidence ofpapillary hypernephroma which was reported to have more good prognosis than non-papillary hypernephroma. So, itcan be suggested that if a hypernephroma show hypovascularity on angiography or predominantly low echogenicity onultrasonography, it has a good prognosis than hypervascular or predominantly high echogenic hypernephroma.

The ability of several species of streptococcus and staphylococcus to adhere to human buccal epithelial cells was studied in vitro by using bacteria and epithelial cells isolated from human buccal cavity. Viridans streptococci were found adhering in highest numbers(65 +/- 8 bacteria per epithelial cell) to epithelial cells. Streptococcus pyogenes adhered in great numbers (44 +/- 4), whereas Streptococcus pneumoniae (26 +/- 2), Staphylococcus aureus (21 +/- 2), Staphylococcus epidermidis (14 +/- 2) adhered poorly. These data showed that bacteria differed in their ability to adhere to human buccal epithelial cells. This difference in adhesive ability between bacterial species may correlate with the ability of the bacteria to colonize oral surface of human.

The human major histocompatibility complex HLA is located on the short arm of chromosome 6. It is known to be the most polymorphic genetic system in humans. The biological role of the HLA class I and class II molecules is to present processed peptide antigens. The HLA system is clinically important as transplantation antigens. Molecular HLA allele typing is routinely performed to provide HLA class I and class II allele matching in unrelated donor hematopoietic stem cell transplantation. Prospective lymphocyte crossmatching is critical in solid organ transplantation to prevent allograft rejection. HLA alloimmunization causes various problems in transfusion therapy. The HLA system is associated with certain diseases, but its underlying mechanisms are not yet fully explained.

The study of the HLA system was primarily initiated to understand the basis for the histocompatibility between recipients and tissue donors. HLA typing methods are being continuously improved and biochemical and molecular typing, in particular, are expected to provide precise typing of the HLA system. Conventional HLA typing methods can define antigen specificities, while biochemical and molecular methods will provide direct allele typing that is based on the actual sequence polymorphism. The precise tissue typing will definitely improve the outcome of transplantation. Structural studies have revealed the highly polymorphic nature of the HLA system and given insight to understanding the molecular basis of the HLA polymorphism. One big immunological puzzle remaining to be answered is how T-cell receptor molecules recognize peptide antigen in conjunction with the HLA molecule. The crystallization of the T-cell receptor molecule, an experiment currently underway, will eventually reveal the structural basis of the trimolecular interaction.

In paediatric orthopaedic, it has been discovered that the fracture of the epiphyseal plate may cause not only growth disturbances but also progressive deformity upon appendicular skeleton of a growing child. Between 1972 May and 1983 April, 102 inward patients(106 cases) who were 18 years old or younger were treated in the department of orthopaedic surgery of Hanyang University Hospital because of epiphyseal plate fractures. The results were summerized as followings: 1. The peak age was from 5 years to 14 years(average, 10.2 years old). 2. The sex ratio was 4.3 for male to 1 for female. 3. The left side was involved more frequently than the right extremity. 4. The most common cause of fractures was injury on fall down(in 41.4% of all cases). 5. The incidence of epiphyseal fracture was 8.1% of fracture in children. 6. The most common fracture was developed at humeral epiphysis. 7. The most common type of epiphyseal fracture was Salter and Harris type IV. 8. The 50.5% of all cases was treated by closed reduction and cast immobilization, 48.1% by open reduction and internal fixation, and 1.9% by closed reduction and traction. 9. The average period of immobilization was 5.2 weeks. 10. The incidence of complication of all cases was 13.2%, but only 2 cases of them(1.9%) were needed for operation because of their complication.

PURPOSE: To evaluate a recently developed technique to place a medium-duration(weeks to months) central venous access. MATERIALS AND METHODS: Within three-year period, 635 patients were referred to interventional radiology suite for placement of peripherally inserted central catheter(PlCC). Contrast medium was injected into the peripheral intravenous line and a puncture was made into the opacified vein near the junction of the middle and upper thirds of the upper arm, either the brachial or basilic vein under fluoroscopic guidance. A 5.5-French peel-away sheath was inserted into the vein and a 5- French silicone catheter was introduced with its distal tip to the junction of the right atrium and superior vena cava. RESULTS: Catheter placement was successful in all patients unless there was a central venous obstruction. Catheters were maintained from 2 days to 5 months with a mean of 3 weeks. Complications included infection requiring removal of the PICC in 16 patients(2.5%), acute thrombosis of the subclavian vein in 3(0.5%). Occluded catheters in 4 patients were easily cleared with urokinase in place. CONCLUSION: The PICC system is an excellent option for medium-duration cen- tral venous access. Patients were able to carry on normal activities with the catheters in place.

PURPOSE: To evaluate the incidence of genitourinary mycoplasmas and the efficacy of antibiotics in women with overactive bladder (OAB) symptoms. MATERIALS AND METHODS: Women with OAB symptoms (micturition > or =8/24 hours and urgency > or =1/24 hours) for > or =3 months were screened for Mycoplasma hominis (M. hominis), Ureaplasma urealyticum (U. urealyticum), and Chlamydia trachomatis (C. trachomatis). Specimens from urethral and cervical vaginal swabs were examined for M. hominis and U. urealyticum by using the Mycoplasma IST2 kit and for C. trachomatis by using PCR. Women with positive results were treated with a 1 g dose of azithromycin. Persistent infection was treated with doxycycline. Changes in a 3-day bladder diary, Patient Perception of Bladder Condition (PPBC), and International Consultation on Incontinence Questionnaire-Female Lower Urinary Tract Symptoms (ICIQ-FLUTS) were evaluated 4 weeks after negative conversion. Patient satisfaction was assessed. RESULTS: Of 84 women screened, 42.8% were positive (U. urealyticum, 40.5%; M. hominis, 7.1%; C. trachomatis, 3.6%; two organisms, 8.3%). After treatment, 82.7% obtained negative conversion, and their median number of micturition episodes decreased from 10.6/24 hours to 8.1/24 hours (p=0.002). PPBC and domain scores of the ICIQ-FLUTS (filling and quality of life) significantly improved. About 87.5% women with negative conversion were satisfied with the treatment. CONCLUSIONS: Considering diagnostic tests and treatment for genitourinary mycoplasmas might be beneficial before invasive workup or treatment in women with OAB symptoms.

OBJECTIVE: Dopamine plays a key role in the proliferation regulation of the smooth muscle cells. The purpose of this study was to observe the degree of expression of dopamine D1 and D2 receptors and dopamine transporter (DAT) and to evaluate the influence of methylation about control of expression of DAT in uterine leiomyoma and normal myometrial tissue. METHODS: In 20 patients who underwent hysterectomy due to uterine leiomyoma, normal myometrial and leiomyoma specimens were obtained. The expression of dopamine D1 and D2 receptors and DAT was demonstrated by using RT-PCR and immunohistochemistry in each normal myometrium and leiomyoma. Analysis of the DNA methylation status of DAT was conducted using HpaII digestion and the methylation-sensitive PCR. RESULTS: The mRNA level of dopamine D1 receptor was relatively higher in normal myometrium than D2 receptor and it was also unchanged in leiomyomas. However, the mRNA levels of dopamine D2 receptor and DAT in leiomyomas were much higher than normal myometrium. Consistent with elevated mRNA levels, high levels of dopamine receptors protein expression were detected by immunohistochemistry in leiomyomas. The degree of methylation at CpG sites of the area intron 1 of DAT (genomic position, +377 - +888) was decreased in leiomyomas. CONCLUSION: These results suggest that overexpressed dopamine D2 receptor and DAT would be associated with proliferation of human uterine leiomyomas and the methylation status of the CpG island of DAT determines its expression.
