Adenosine deaminase (adenosine aminohydrolase, AL)A), which catalyzes the deamination of adenosine to yield inosine and amrnonia, was assayed in human penile foreskin. The skin tissue was separated into two layers; epidermis and dermis. They were sliced with scissors into gel state, 4 volumes of 0.05M phosphate buffer solution were added and the tissue homogenized. After centrifugation at 4,000xg for 5 minutes, the supernatant was used as an enzyme solution. ADA activity was measured according to the method f Giuseppe" ADA was found to be present in both layers (epidermis; 0.24 OD/mg protein, dermis; 0.19 OD/mg protein) with slightly higher activity in the epidermis. As in earlier reports, it was found that ADA in the skin showed nearly even activity in the pH range of 5.0-8.0. Considering the significance of ADA in immunological function, the presence of ADA in the skin suggests that the tissue may participate in the immune function.

We have experienced a case of congenital esopageal atresia which was confirmed by autopsy. A 3 days old female infant, birth weight 2,300gm, length 48cm, was admitted to Dept. of Pediatrics, Chonnam University Medical school because of poor sucking power, fever and vomiting. On admission, she was kept in an incubator and whole milk was giver per oral, followed by immediate vomiting and regurgitation through mouth and nose, accompanied by dyspnea and cyanosis. A Nelaton catheter was inserted through the esophagus but met a solid obstructed region at 15cm from the nares. A plain abdomen showed no air in the upper gastrointestinal tract, and in esophagogram with air and Dionocil, esophageal atresia without tracheoesophageal fistula was shown. Gastrostomy was performed but 6 days after operation, she expired. The autopsy findings revealed blind pouched upper esophagus with dilatation at 2nd thoracie spine level and blind pouched lower esophagus just below the diaphragm. A brief review of related literature is also noted.

OBJECTIVES: Although bronchoscopy is an important diagnostic tool for lung disease, patients compliance is low due to discomfort. Recently, midazolam which has a favorable anterograde amnesia effect and short action duration, has been used to relieve patients discomfort during bronchoscopy. Midazolam was investigated in order to see the beneficial effect and safety during bronchoscopy. METHODS: The study design was single blind, randomized, prospective. 102 patients were included, in whom bronchoscopy was performed between June, 19% and October, 1995 at Samsung Medical Center. They were categorized into midazolam group and control group. Patients were asked about the amnesic effect, discomfort of procedure and the willingness to repeat procedure. The consciousness level of patients during procedure, patient cooperation during procedure and ease of procedure were also reported by bronchoscopists. RESULTS: 1) The difference of oxygen saturation between two groups: There was no significant difference in oxygen saturation between midazolam group and control group before and after bronchoscopy. During procedure, however, mean oxygen saturations in midazolam group (90+/-6.4%) was significantly lower than in control group (93+/-4.7%)(p<0.05). 2) Evaluations by patients (1) Effect of amnesia: 41 patients (82%) in midazolam group could not recall the procedure but 52 patients (100%) recalled the entire procedure in control group. A favorable amnesic effects could be found in midazolam group(p<0.05). {2) The discomfort during the procedure: 43 patents(86%) did not experience discomfort from procedure in midazolam group but 25 patients(48%) complained of discomfort in control group (p<0.05). (3) Most patients except two(96%) were willing to repeat fiberoptic bronchoscopy in midazolam group but 13 patients (25%) answered that they would never repeat bronchoscapy. There was a statistically significant difference between two groups in the willingness to repeat bronchocopy (p<0.05). 3) The evaluations by bronchoscopists Cooperations of the patients and ease of procedure were not different between two groups. The patients in midazolam group except eight could not respond to verbal stimuli but most patients were awakened during procedure in control group(p<0.05). CONCLUSION: Midazolam is a good sedative agent for a patient to give a favorable amnesia, reduction of discomfort during bronchoscopy. We concluded that midazolam is a safe and useful sedative agent and midazolam may be used routinely during bronchoscopy. Monitoring of oxygen saturation, however, is essential to prevent severe hypoxia during procedure.

BACKGROUND: We have recently reported that airway epithelial cells can produce RANTES and IL-8 in response to the stimulation of tubercle bacilli wuggesting a certain role of airway epithelial cells in the pathogenesis of pulmonary tuberculosis. The pathogenesis of tuberculosis is determined by several factors including phagocytosis, immunological response of host, and virulence of tubercle bacilli. Interestingly, there have been reports suggesting that difference in immunological response of host according to the virulence of tubercle bacilli may be related with the pathogenesis of tuberculosis. We, therfore, studied the expressions and productions of RANTES and IL-8 in airway epithelial cells in response to tubercle bacilli(H37Rv, virulent strain and H37Ra, avirulent strain), in order to elucidate the possible pathophysiology of pulmonary tuberculosis. METHODS: Peripheral blood monocytes were isolated from normal volunteers. Peripheral blood monocytes(OBM) were stimulated with LPS(10 micrograms/ml), H37Rv, or H37Ra(5X10(5) bacilli/well) along with normal control for 24 hours. A549 cells were stimulated with supernatants of cultured PBM for 24 hours. ELISA kit was used for the measurement of TNFalpha and IL-1beta production in supernatants of cultured PBM and for the measurement of RANTES and IL-8 in supernatants of cultured A549 cells. Northern blot analysis was used for the measurement of RANTES and IL-8 mRNA expression in cultured A549 cells. RESULTS: TNFalpha and IL-1beta productions were increased in cultured PBM stimulated with LPS or tubercle bacilli(H37Rv or H37Ra) compared with the control. There was, however, no difference in TNFalpha and IL-1beta production between cultured PBM stimulated with H37Rv and H37Ra. RANTES and IL-8 expressions and productions were also increased in cultured A549 cells stimulated with LPS or tubercle bacilli compared with the control. RANTES and IL-8 mRNA expressions were significantly increased in cultured A549 cells stimulated with H37Ra-conditioned media(CM) compared with A549 cells stimulated with H37Rv-CM (p<0.05). However, there was no difference in RANTES and IL-8 productions between A549 cells stimulated with H37Rv-CM and H37Ra-CM. CONCLUSION: Airway epithelial cells can produce the potent chemokines such as RANTES and IL-8, in response to the stimulation of tubercle bacilli. These results suggest that airway epithelial cells may play a certain role in the pathogenesis of pulmonary tuberculosis. However, the role of airway epithelial cells in the pathogenesis of tuberculosis according to the virulence of tubercle bacilli was not clear in this study.

BACKGROUND: Klebsiella pneumoniae is an opportunistic pathogen which causes a spectrum of extra- intestinal infections. Since early 1980s, many outbreaks of extended-spectrum beta-lactamase (ESBL) producing K. pneumoniae have been reported. Using quinolone as an alternative therapeutic antibiotics also induced increased resistance to quinolones. Therefore, we evaluatedted the clinical and microbiological features of pneumonia caused by quinolone-resistant K. pneumoniae (QRKP). METHODS: From March of 1998 to April of 2000, 345 cases of K. pneumoniae pneumonia had been admitted to Korea University Guro Hospital. We retrospectively reviewed medical records of 75 cases. Thirty patients with pneumonia due to QRKP (case patients) were compared to 45 patients with pneumonia due to quinolone-susceptible K. pneumoniae (QSKP: control patients). We also performed antimicrobial susceptibility test (disc diffusion method and agar dilution method) and RAPD (random amplified polymorphic DNA) analysis to differentiate the isolates in resistant strains. RESULTS: Of 345 episodes of pneumonia, 30 (8.7 %) were caused by QRKP. Multivariate analysis re-vealed that prior antibiotics use was an independent risk factor for QRKP pneumonia. Among prior antibiotics, quinolone and the third generation cephalosporin were independently related to quinolone resistance. Although mortality rate was not high, QRKP pneumonia was associated with a significantly longer treatment duration and poor treatment response (P=0.009 and 0.007 respectively). According to the antimicrobial susceptibility test, quinolone resistance was significantly associated with the multi-drug resistance. RAPD analysis showed that 28 quinolone resistant strains belonged to only 4 genotypes, suggesting that patient- to-patient transmission of a few strains within the hospital occurred. CONCLUSION: QRKP pneumonia had a significant impact on clinical outcome and quinolone resistance was associated with multiple resistance to other antibiotics. It should be emphasized that judicious use of antibiotics as well as barrier precautions is required to reduce future outbreak and spread of QRKP.

Herpetic meningoencephalitis is a devastating disease with significant morbidity and mortality. One of the most serious clinical sequelae is aphasia, usually of sensory type, whereas, Broca's or motor aphasia is not a common manifestation. We report a case of herpetic meningoencephalitis diagnosed by polymerase chain reaction (PCR) and viral culture with Broca's aphasia as a neurologic sequela. A 35-year old male patient was admitted due to fever and altered mentality for 3 days. He was accompanied by nausea, vomiting, disorientation, and memory defect. Several vesicular eruptions were noted around the lips. Neck stiffness was present, but Kernig's and Brudzinski signs were not observed. Herpetic meningoencephalitis was confirmed with PCR and other diagnostic tests such as EEG, brain MRI, brain CT scan, and viral culture. His overall clinical condition was improved after acyclovir therapy, but Broca's aphasia remained as a sequela.

This study was undertaken to evaluate the present status of intestinal helminthic infections in Koreans, from April 1967 through May 1969. The nationwidely collected stool specimens and scotch-tape anal swabs from primary schoolchildren, middle school students, draftees to army recruitment camp, soldiers and inhabitants of various parts of Korea were examined. The methods employed were Kato's cellophane thick smear technique and formalin-ether sedimentation technique in 40,581 for the prevalence rate of various intestinal helminths, scotch-tape anal swab technique in 8,585 for the prevalence rate of Enterobius vermicularis and by Stoll's dilution egg counting technique in 1,174 for the evaluation of the worm burden of some helminths. The results are as follows. Result of stool examination: The positive rate of intesinal helminthes of any kind was 90.5% among 40,581. In rural people, it was 92.3% in average in contrast to 85.0% in Seoul inhabitants. The infection rate of A. lumbricoides in 40,581 was 58.2%. It was higher in rural people 62.9% than in Seoul inhabitants and highest in 5-9 year-old group by age. The infection of Trichocephalus trichiurus showed the highest prevalence rate in Koreans and it was 74.5%. No remarkable difference was observed between Seoul inhabitants(72.2%) and rural people(75.2%). The tendency of higher prevalence rate with the older age group was observed. The infection rates of hookworm and Trichostrongylus orientalis in 40,581 examinations by cellophane thick smear were 5.1% and 5.8% respectively. But in 4,949 examinations for which refined cellophane thick smear technique and formalin-ether sedimentation technique were employed, the infection rates were turned out 17.6% in hookworm and 15.9% in T. orientalis. Although rural people showed higher infection rate of hookworm(18.8%) than Seoul inhabitants(13.8%), the reverse was true in T. orientalis infection rate(14.5% : 20.3%). Both kinds of infections were tend to be higher with the increase of age. The infection rates of Clonorchis sinensis and Metagonimus yokogawai were 4.7% and 0.4% respectively. In both kinds of infections male showed higher infection rates than female and the tendencies of higher infection rate in the older age group were observed. The provinces which showed the higher infection rate of C. sinensis were South and North Kyongsang Do and North Cholla Do, all of which are provinces of southern part of Korea. Some endemic foci of M. yokogawai were noticed in South Kyongsang Do and South Cholla Do. The infection rate of Taenia spp. by applying only the stool examination was 0.7% throughout the survey. No sex difference in infection rate of Taenia spp. was noticed, but in older age group it was increased. Cheju Do, the island of extreme southern part of Korea seemed the most endemic area and South and North Cholla Do were next in ranking of Taenia infection rate. The ova of Hymenolepis nana were observed in 0.2% and all of them were under the age of 20 except only one caes. The infection rate seemed higher in female (0.3%: 0.1%). No geographical difference was noticed except 1.1% of schoolchilderen and students of Cheju Do. Result of Scotch-tape anal swab technique for E. vermicularis infection. The infection rate of E. vermicularis in 8,585 urban and rural schoolchildren and rural inhabitants was 46.6%. Female (57.9%) had definitely higher infection rate than male (41.4%). The infection rate was significantly higher in rural people than Seoul schoolchildren. The exteme example was 79.7% in schoolchildren of South Cholla Do. Result of worm burden examination by Stoll's dilution egg-counting technique: Among 1,174 examinations, countable(E.P.G.> 100) cases of A. lumbricoides were 745(63.5%) and the mean E.P.G. was 9,723. The mean E.P.G. in Seoul inhabitants was 5,835 in contrast to 10,820 in rural people. The age group of 5-9 showed the heaviest mean E.P.G., 11,337. 70.6% of 745 cases were less than 10,000 in E.P.G. which means light infection. Countable cases by Stoll's technique for T. trichiurus ova were 63.5% and mean E.P.G. was 649. No difference between Seoul and rural inhabitants was observed. Grade I and II in which E.P.G. is less than 5,000 involve 99.3% of positive cases. 91 cases (7.9%) in 1,174 were positive for hookworm ova by Stoll's technique and mean E.P.G. was 501. All cases were in Grade I and II which were less than 5,000 in E.P.G. Trichostrongylus orientalis was positive only in 25 cases (2.1%) by Stoll's technique and mean E.P.G. was 340. No cases were found to have more than 5,000 in T. orientalis E.P.G. The mean E.P.G. of Clonorchis sinensis among the referred cases of clonorchiasis to Department of Parasitology, Seoul National University, was 9,416. On the other hand mean E.P.G. of C. sinensis was 21,376 among cases in the hyperendemic area of Kimhae, South Kyongsang Do, and 3,073 in cases from other various localities. Among referred clonorchiasis cases to our Department, 21.6% were turned out to have the E.P.G. more than 10,000. The cases who have the E.P.G. more than 10,000 in hyperendemic area, Kimhae were 40.7% and in other various localities were 9.1%
