Intracavernous (IC) injection therapy of vasoactive agents is now being widely choser as the first armamentarium for the treatment of male erectile dysfunction, nevertheless, has a troublesome problems due to the drug delivery vehicle with needle. Therefore, the less invasive route of drug administration has been needed. We investigated the efficacy and safety of intraurethral (IU) instillation of lyposomal prostaglandin E1 on the induction of penile erection. Thirty patients with male erectile dysfunction were enrolled in a prospective study. Overall, 73.3% of cases were responded with 33.3% of full erection and 40% of partial erection after IU instillation. IU self-instillation at home was more effective than at clinic on the induction of penile erection. It is somewhat effective in cases of diabetogenic, psychogenic, neurogenic and mild vasculogenic erectile dysfunction but much less effective in severe vasculogenic and cavernosal disease. Interval of onset and duration of erection were delayed and shortened in IU instillation rather than IC injection. Side effect were mild and transient urethral pain with the most frequent incidence and followed by transient hypotension in less. In conclusion, intraurethral instillation of lyposomal prostaglandin E1 can be selected as one of therapeutic modality to restore the penile erection for some limited patients with erectile dysfunction to want to select a less invasive treatment lternative.

Although percutaneous abscess drainage has become and accepted alternative from of therapy for selected patients with abscess, it is well known that there are several factors in the failure of adequate drainage such as pre-and post- procedural management, technique itself, various features of abscess, and selection and application of catheters. Among these factors, we made an experiment about drain efficacy of commonly used various catheters with different viscosities of water-glycerin solution under the two different pressure gradients. The experimental values of flow rate were lower than than the calculated values. An efficacy of experimental value was 4-14%. Because the inner diameter of fittings and stopcocks was usually smaller than the inner diameter of catheters, these factors also affected the drain efficacy. Finally, we though that it will be very helpful to the treatment of patients as well as to study about the catheter drainage, if the drain efficacy of individual catheters has been notified.

A group of the 59 patients (64 kidneys) of renal calculi, operated at our hospital in the past a half and four years from 1976 Jun. to 1980 May, was investigated statistically. 1. In the 64 operations there were 2 nephrectomies (3.1per cent), 12 pyelolithotomies (18.8 percent), 4 nephrolithotomies (6.3 per cent), 16 extended pyelolithotomies (25.0 per cent), 19 extended pyelolithotomies combined with local nephrolithotomies (29.7 per cent), 5 partial nephrectomies (7.8 per cent), and 6 lower pole pyelocalycotomies (9.4 per cent). From our experience the choice of surgery staghorn or multiple stone was indicated lower surgery is the treatment of choice most of the patients and nephrectomy was performed only in a small group. 2. In 62 conservative operations for renal calculi, residual calculi were observed in 6 kidneys (9.7 per cent). 3. In postoperative course, hematuria was discontinued within 3 days. Urine leakage also disappeared within 3 days in pyelolithotomy with closure of renal pelvis, but within 5 days in extended pyelolithotomy without closure of renal pelvis. In some cases, postoperative urinary tract infection was perpetuated by residual stone and preoperative infection.

One hundred seven isolates of Staphylococcus aureus from bovine mastitis were investigated for colony morphology in serum-soft agar (SSA), autoagglutination in salt, and capsular serotype. Capsular polysaccharide (CP) was purified and quantified from the extracts of clinical isolates. Overall, 89 isolates (83.2%) were diffuse in the SSA, without any difference in the proportion of diffuse colony between type 5 and type 8 strains. Some strains exhibited compact colonies in the SSA and expressed CP as determined by an enzyme-linked immunosorbent assay, indicating that compact morphology does not exclude encapsulation. The majority of the strains (11/12) showed autoagglutination in the salt aggregation test. The serotype 336 accounted for 46.7% of the isolates followed by serotype 5 (12.1%) and serotype 8 (12.1%). Particularly, twenty-six (24.3%) isolates reacted with two serotypes; 7 for type 8/336 and 19 for type 5/336. Five isolates (4.7%) were nontypeable with monoclonal antibodies specific for CP serotype 5, 8, or 336. The CP concentration in culture supernatants varied with the serotypes, and the total amount of CP produced by cells grown in a liquid medium was much less than that produced by cells grown on a solid medium. The Western blotting indicated that the CP bands of S. aureus serotype 5 and 8 were ranged in the molecular mass of 58-84 kilodalton (kDa), with additional bands in the region of approximately >or= 48 or

PURPOSE: Penile size has been a focus of interest in the life and the culture throughout human history. It has been a longstanding question whether there is any relation between penile size and the dimensions of body extremities. We measured the standard length of the penis and investigate whether any body extremity is a predictive index of penile size in Korea men. PATIENTS AND METHODS: A series of 655 males above 17 years of age were examined during a 4-month period. Stretched penile length, penile circumference, and length and characteristics of various body parts and features (1st finger, 2nd finger, 3rd finger, 1st toe, 2nd toe, 3rd toe, ear, mouth, nose, height, weight, and baldness) were investigated by one examiner. To see the relation among the penile length and circumference and various body dimensions, univariate and multivariate statistical methods such as correlation analysis and multiple linear regression were applied. RESULTS: The mean values standard deviations were 46.6 +/- 18.4 for age, 10.0 +/- 2.0 cm for the length of the penis, and 8.5 +/- 1.0 cm for the circumference of the penis. In a correlation coefficient analysis, the length of the penis was slightly correlated with penile circumference. Additionally, the circumference of the penis was slightly correlated with penile length, patient height, weight, and 3rd toe and 1st toe length, in decreasing order. In a multivariate analysis, the coefficients of determination from multiple linear regression were 13% and 15% for the length and the circumferences of the penis, respectively. CONCLUSIONS: Human body index including the size or characteristics of body extremities is not enough to predict the penile size.

Mutation of the p53 tumor-suppressor gene in exons 4 through 9 was examined in 34 cases of primary advanced gastric cancer using PCR-SSCP (polymerase chain reaction-single strand conformation polymorphism) and the results were compared with p53 protein expression as determined by immunohistochemistry (IHC) using a monoclonal antibody(DO-1). p53 protein detected by IHC was observed in 14 cases (41.2%) and genotypic mutation detected by PCR-SSCP in exons 4-9 was observed in 13 cases (38.2%) One case showed an aberrant band on PCR-SSCP both in Exon 7 and Exon 8/9. p53 alteration detected by either IHC or PCR-SSCP was observed in 19 cases (55.9%), but only 8 cases (23.5%) showed both p53 mutation and protein expression. We also tried to obtain the correlation between relative intensity of the shifted bands on PCR-SSCP and percentage of positive cells by IHC, but a significant correlation was not seen between relative intensity of shifted bands on PCR-SSCP and positve cell ratio. A discrepancy between p53 protein expression and p53 mutation is observed in primary gastric carcinomas. The reason for this discrepancy are not apparent. However, examination of gastric carcinomas for mutations in other exons may identify a better correlation with protein overexpression. The results obtained in this study suggest that the negative reaction for p53 immunohistochemistry may not necessarily mean no genetic alteration of the p53 locus.

Cortical dysplasia is a cause of intractable epilepsy and a candidate for surgical resection to control epileptic attacks. The neuronal cytomegaly and balloon cell change are the diagnostic hallmarks of cortical dysplasia. Little research has been performed about the normal-sized dysplastic neuron which has complex arborizing dendrites and lacks in its polarity. The aim of this study was to define the histopathologic characteristics of the neurons in cortical dysplasia. Twelve cases of cortical dysplasia who underwent partial lobectomy for intractable seizures were selected and immunohistochemical staining for NF-M/H, MAP2, tau, and ubiquitin was performed. The perikarya and dendrite of dysplastic neurons were more intensely labeled with antibodies for the high and medium molecular weight neurofilament proteins (NF-M/H) than normal neurons. Immunoreactivity with the MAP2 antibody expressed mainly within the somatodendritic regions was present in the dysplastic or normal neurons without any significant difference in intensity. The complex arborizing dendrites of dysplastic neurons were easily identified due to pronounced immunoreactivity within the somatodendritic regions. Immunoreactivity with the primary antibody against tau and ubiquitin was present in the normal-looking neurons as well as the dysplastic neurons. This study suggests that the dysplastic neurons in cortical dysplasia are accompanied by changes of cytoskeletal neurofilaments, and the immunohistochemical stains for NF-M/H, MAP2, tau, and ubiquigin are useful to detect them.

PURPOSE: There have been repoty on radiological features of lower respiratory track infection in infants and children caused by RSV(respiratory syncytial virus) in KOREA. The aims of this study were to summarize radiological features of lower respiratory tract infection caused by common viral agents other than RSV and to find any specific radiological features which might provide clue to the etiologic diagnosis. MATERIALS AND METHODS: We retrospectively analyzed radiological features in 51 children with symptoms of lower respiratory tract infection and identification of viral agents(except RSV). They included parainfluenza (n=22), adenovirus(n=16), influenza A(n--11), influenza B(n=2) virus infections. The mean age of the patients was 23 months. RESULTS: Major radiological findings of viral lower respiratory tract infection were bilateral parahilar peribronchial infiltration(62%), bilateral overaeration(60%), atelectasis(59%)(segmental or subsegmental atelectasis(43%), Iobar atelectasis(16%)) and patchy or confluent consolidation(20%). Pleural effusion was seen in only one case and hilar adenopathy was not observed in any of them. In the cares of adeno virus, consolidation was seen in 5 cases(31%) including 3 cases919%) of extensive confluent consolidations and overaerations were less frequent findings(44%) than in other viruses. In 24 patients with radiological follow up for more than 1 week, consolidation improved most rapidly, while was persistent atelectasis. CONCLUSION: The major radiologic features in vital lower respiratory tract infection(except RSV) were overinflation, bilateral peribronchial infiltration and atelectasis. In adenoviral infection, confluent consolidations which are usually seen in bacterial pneumonia were more common findings than in other viral lower respiratory tract infections.
