BACKGROUND: Glycolic acid is currently reported to have beneficial effects on the photoaged skin. These effects may be through the modulatory action of glycolic acid in the production of dermal extracellular matrix proteins of fibroblast. OBJECTIVE: The aim of this study was to investigate the specific effect of glycolic acid on the collagen and elastic fiber gene expression in vitro. METHODS: Human skin fibroblasts were cultured from normal skins of excised specimens and glycolic acid (75 µg/ml) was treated. After 24 hours of treatment, six each cell lines were processed for extraction of RNA and subjected to Northern analysis. RESULTS: Type I collagen mRNA expression was significantly increased in the glycolic acid-treated fibroblasts. Elastin mRNA expression did not show any significant change. CONCLUSION: These results suggested that glycolic acid induced the increase of type I collagen mRNA expression and had the specific biologic effect on fibroblast.

There have been many reports on cerebrovascular disease in Korea, almost all of which were done at the Department of Neurosurgery, Neurology, and Internal Medicine. It is established that hemorrhagic stroke(HS) occurs at a higher rate than ischemic stroke(IS) compared to Western societies. However, many patients with IS visit to Oriental Medicine in Korea. Because of the paucity of published information including stroke data of Oriental Medicine, it was our purpose to analyse characteristic pattern of stroke occurrence, clinical data, and outcome for 762 patients visited to emergency room or admitted to the University Hospital and Oriental Medicine for a twelve month period. The incidence of IS was at least 1.5 times that of HS(IS: 309, HS: 453). Among age groups, those in sixties and seventies were the most predominant. The distribution of patients according to each Departments and Oriental Medicine was 118(HS: 2, IS: 116) in Department of Internal Medicine, 286(HS: 251, IS: 35) in Neurosurgery, and 358(HS: 56, IS: 302) in Oriental Medicine. The overall outcome for HS are much poorer than those for IS: in HS, 69.6% good, 10.7% morbidity, and 19.7% mortality, and in IS, 83.2%, 13.0% and 3.8%, respectively. Considering the fact that many IS patients with mild symptoms and signs tend to visit private clinics, these results suggest the actual incidence of Is is much higher than HS in Korea, compared with previous reports. We expect that a multicentered cooperative study including Oriental Medicine will be motivated by this study for establishing more accurate characteristics of stroke in Korea in the future.

Korean Journal of Urology 1982;23(6):739-744
Urine specimens were obtained from one hundred and thirty nine patients in-out-patient and in-patient service of B.N.U.H., Dept. of Urology, with the presumptive diagnosis of urinary tract infections or indwelling catheter. These specimens were processed by Triphenyltetrazolium Chloride test, quantitative test and identification of the organisms. The results were as follows: 1. Triphenyltetrazolium Chloride test was an easily performable and a fairmely accurate method for screening of urinary tract infections. 2. The urine specimens showed false negative reactions to triphenyltetrazoium Chloride in some cases with moderate (10(4) to 10(6) bacteria per milliliter) growth of bacteria or in the antibiotics used patients. 3. The incidence of urinary tract infections with gram negative bacilli are ninety-two percent. In their series, incidence of E. coli decreased and that of other gram negative bacilli increased such as Enterobacter, Proteus and Serratia, etc. This shift in the pathogen spectrum occurs mostly in the patients of complicated or lower urinary tract infections, in-patients, antibiotics used patients and the patients with indwelling catheter.

We conducted a retrospective study of 20 penetrating keratoplasty (19patients) for corneal opacity due to herpes simplex keratitis from January 1992 to February 1997 at National Medical Center. We exaniined f requeuey of graft rejection and recurrence of herpetic keratitis after penetrating keratoplasty. The patients were grouped into control & treatinent, group according to the use of antivirial drug after penetrating keratoplasty and we examined the difference in rate of recurrence between two groups. The follow-up period was from 8 months to 68 months, mean follow-up period being 29.6 months. Graft rejection was seen in 3 eyes out of 20 eyes (15.0%) and recurrence was developed 3 eyes out of 20 eyes (15.0%). Recurrent herpetic keratitis developed in 15.4%(2 of 13) of the eyes in control group and 14.3% (1 of 7) of the eyes in treatment group. There was no statistically significant difference in recurrence rate between two groups (p)0.05). Postoperative prophylactic antiviral treatment is not associated with decreased rate of herpes simplex keratitis recurrence.

The authors have evaluated the effect of topically applied 1% cyclosporine A for four weeks after limbal allograft transplantation for ocular surface stability in severely ocular surface damaged rabbits. A total eleven severely damaged rabbits were subdivided into three groups of four limbal autograft (AUTO), three limbal allograft (ALLO), four limbal allograft with topical application of 1% cyclosporine A five times daily for four weeks (ALLO-C). We examined ocular surface smoothness, clarity, corneal vascularization before surgery and three months after surgery, and classified three grade (success, partial success, failure) according to result. In AUTO, three eyes were success, one eye was failure. In ALLO, one eye showed inferior graft detachment and one eye was success, two eyes were failire. In ALLO-C, no graft detachment detected and one eye was success, two eyes were partial success, one eye was failure. We knew that. ALLO-C show more effective ocular surface stability than ALLO. These result suggest ALLO-C can be used as alternative treatment of AUTO in ocular surface reconstruction. But, rnore study for duration and concentration of cyclosporin A will be need.

8.Inflammatory Pseudotumor of the Urinary Bladder: A Case Report.
Jeong Moon HEO ; Jong Byung YOON
Korean Journal of Urology 1996;37(4):488-491
Inflammatory pseudotumor of urinary bladder is a rare benign entity that clinically and radiologically simulates a malignant tumor. This benign lesion can easily be mistaken for sarcoma, and only careful pathologic examination can provide a definite diagnosis. It is important to recognize this lesion as benign to avoid the potentially serious consequences of misdiagnosis. A 53-year-old man presented with a history of micturition pain and urinary frequency despite of symptomatic treatment with antibiotics for 2 weeks. Cystoscopic examination, ultrasonography and of revealed a well defined mass with central necrosis. The mass was located at the left lateral wall of the bladder, and it was 3x3 cm sized round shape. We suspected benign tumor by above diagnostic modalities and we confirmed inflammatory pseudotumor by frozen section of mass, followed by partial cystectomy was performed. Awareness of this unusual lesion is important to prevent unnecessary surgical procedure. We report a case of inflammatory pseudotumor of the urinary bladder and reviewed 21 cases of this disease including our case.

Korean Journal of Urology 1994;35(10):1151-1155
The congenital patent urachus is the failure of complete urachal lumen closure and results in a free communication between the bladder and the umbilicus. Embriologically the urachus represents the vestigial remnant of the allantois which, in the fetus, communicates with the cloaca. The first patient is a 6-day-old female infant, and she was transferred due to urine leakage from the reddish hen egg sized protruding mass on the umbilicus. The fistulogram showed a long fistulous tract which communicates with bladder and umbilicus. A complete resection of the patent urachus was done. The second patient is a 1-day-old male infant, and he was transferred for operation of omphalocele from local clinic. Urine leakage was detected from the urachus at operative field, and so complete resection of the urachus was performed, and the one stage repair was performed for treatment of mild intestinal herniation. Postoperative courses of the two cases were uneventful.

Moon Kee JEONG ; Jong Byung YOON
Korean Journal of Urology 1983;24(1):127-132
True hermaphroditism is one of the rare congenital anomalies. Additional four cases of this anomaly are added to the 2 cases which were reported previously from the Dept. of Urology, Busan National University Hospital. Clinical review was performed about these 6 cases. The results were as follows; 1. The incidence of true hermaphroditism is 0.17% in 3,456 uro1ogicaladnrissions from Jan. 1964 to Mar. 1982, 1.6% in 380 admissions with congenital anomalies of the external genitalia and 25% in 24 admissions with hypospadias and cryptorchism during this period. 2. Hypospadias and cryptorchisrn are found in 6 cases, bifid scrotum 3 cases, and labioscrotal folds in 2 cases. Roentgenograms of retrograde urethrography were available in 4 cases and revealed blind vaginal pouch in 3 cases. Among these 3 cases, one had patent fallopian tube at the cephalad end of the pouch. The other one had well developed vagina and the uterus with patent fallopian tube. 3. The genital ducts were developed ipsilaterally in 9 gonads composed of pure testicular or ovarian tissues but developed to those of male pattern in 3 gonads containing the ovarian and testicular tissues. Among these 3 cases two cases did not have the vas deferens. 4. Of 6 gonads containing the testicular tissues, two were in the scrotum, 2 in inguinal and remained 2 were in the peritoneal cavity. Of gonads containing the ovarian tissues, seven were in the peritoneal cavity and one in the retroperitoneum. 5. Sex chromatin was positive in 3 cases, negative in 3 cases. 6. Of 5 cases who had been reared as male, two were assigned to female, one to male and remained 2 were not decided the sex. The other who had been reared as female was assigned to female. 7. The type of true hermaphroditism is lateral in 3 cases (Type I)and unilateral in 3 cases (Type IIIb 2 cases, Type IIIa I case)by the classification of Jones and Scott.
