Emphysematous pyelonephritis is an uncommon serious suppurative infection characterized by the production of intrarenal and perirenal gas generally occurs in patient with diabetes mellitus or urinary tract obstruction. We report our experience with the successful management of a case emphysematous pyelonephritis which occurred in 22 year-old diabetic woman with UPJ obstruction in a solitary kidney. She was treated non-operatively with intensive anti-microbial therapy, insulin therapy and percutaneous nephrostomy as a initial life saving procedure. After improvement of renal function and general condition, we performed dismembered pyeloplasty for UPJ obstruction.

BACKGROUND: Patients undergoing brain surgery have a high risk of developing a number of perioperative coagulation disorders. Anesthesia and surgical stress may affect blood coagulation and fibrinolysis. The aim of this study was to evaluate perioperative changes in hemostatic parameters of patients undergoing clipping of cerebral aneurysms with a thromboelastograph (TEG) in combination with simple laboratory tests. METHODS: Twenty adult patients who had cerebral aneurysms and no history of coagulation disorders were studied. Isoflurane and N2O were used for all anesthetic proceedings. Preanesthetic, intraoperative (after skin incision and after clipping of cerebral aneurysms) and postanesthetic measurements included a TEG and simple laboratory tests. The TEG variables included r time (reaction time for clot formation), k time (clot formation time), alpha angle (rate of clot growth), MA (maximal amplitude of clot strength) and LY30 (fibrinolytic index). RESULTS: In simple laboratory tests, prothrombin time (PT) and partial thromboplastin time (PTT) at intraoperation and postanesthesia were longer than those at preanesthesia (p < 0.05). In the TEG, r and k time at intraoperation and postanesthesia were shorter than those at preanesthesia (p < 0.05). However the alpha angle at intraoperation and postanesthesia was longer than that at preanesthesia (p < 0.05). There was no significant difference in MA and LY30 except an increase in MA after the skin incision (p < 0.05) compared to the MA at preanesthesia. CONCLUSIONS: These results indicate a general hypercoagulability during and after a cerebral aneurysms operation in terms of TEG, although, the level of the PT and PTT can be at the upper limits within normal. Therefore perioperative use of coagulants in cerebral aneurysms may increase the risk of a thromboembolism because of accelerating blood coagulability. By early intraoperative and postoperativeevaluation of the hemostatic abnormality with a TEG, appropriate measures might be initiated to prevent postoperative complications due to hypercoagulability.

Cryptococcosis is a systemic mycosis that most often involves the lungs and central nervous system and, less frequently, the skin, skeletal system, and prostate gland. Cryptococcus neoformans, the causative organism, is a yeastlike round or oval fungus, 4 to 6microm in diameter, which is surrounded by a polysaccharide capsule and reproduces by budding and found in soil and other enviromental areas, especially those contaminated by pigeon droppings. Humans and aninmals acquire infection after inhalation of aerosolized spores. Condition or factors that predispose to cryptococcosis include corticosteroid therapy, lymphoreticular malignancies, HIV infection, and sarcoidosis etc. We discribed a case of cryptococcosis involving lung and CNS coincidently without specific underlying disease and the literature on subject were reviewed. A fifty-six year-old previously healthy female presented with headache of 3 months of duration. She had no history suggesting immunologic suppression and we could not find any abnormal laboratory findings including blood sugar, serum immunoglobulin and complement level, HIV antibody, and T cell subsets. Chest roentgenogram and CT scan showed a solitary soft tissue mass in LUL with distal pneumonitis. Brain MRI showed granulomatous lesion in cerebellum and parasagittal cortex of right frontal lobe. The diagnosis was made by bronchoscopic brushing cytology, transthoracic fine needle aspiration, and sputum OH mount and culture. She was treated 6 weeks course of Amphotericin B and switched to oral fluconazole therapy for 3 months. Her symptoms and X-ray findings were improved gradually and she is now under regular clinical follow up.

BACKGROUND/AIMS: We investigated the role of representative endoplasmic reticulum proteins, stromal interaction molecule 1 (STIM1), and store-operated calcium entry-associated regulatory factor (SARAF) in pacemaker activity in cultured interstitial cells of Cajal (ICCs) isolated from mouse small intestine. METHODS: The whole-cell patch clamp technique applied for intracellular calcium ions ([Ca²+]i) analysis with STIM1 or SARAF overexpressed cultured ICCs from mouse small intestine. RESULTS: In the current-clamping mode, cultured ICCs displayed spontaneous pacemaker potentials. External carbachol exposure produced tonic membrane depolarization in the current-clamp mode, which recovered within a few seconds into normal pacemaker potentials. In STIM1-overexpressing cultured ICCs pacemaker potential frequency was increased, and in SARAF-overexpressing ICCs pacemaker potential frequency was strongly inhibited. The application of gadolinium (a non-selective cation channel inhibitor) or a Ca2+-free solution to understand Orai channel involvement abolished the generation of pacemaker potentials. When recording intracellular Ca²+ concentration with Fluo 3-AM, STIM1-overexpressing ICCs showed an increased number of spontaneous intracellular Ca²+ oscillations. However, SARAF-overexpressing ICCs showed fewer spontaneous intracellular Ca2+ oscillations. CONCLUSION: Endoplasmic reticulum proteins modulated the frequency of pacemaker activity in ICCs, and levels of STIM1 and SARAF may determine slow wave patterns in the gastrointestinal tract.

OBJECTIVE: The purpose of this study was to establish a minimally invasive and reproducible protocol for estimating the gastrointestinal (GI) transit time in mice using barium and radiopaque markers. MATERIALS AND METHODS: Twenty 5- to 6-week-old Balb/C female mice weighing 19-21 g were used. The animals were divided into three groups: two groups that received loperamide and a control group. The control group (n = 10) animals were administered physiological saline (1.5 mL/kg) orally. The loperamide group I (n = 10) and group II (n = 10) animals were administered 5 mg/kg and 10 mg/kg loperamide orally, respectively. Thirty minutes after receiving the saline or loperamide, the mice was administered 80 microL of barium solution and six iron balls (0.5 mm) via the mouth and the upper esophagus by gavage, respectively. Afterwards, the mice were continuously monitored with fluoroscopic imaging in order to evaluate the swallowing of the barium solution and markers. Serial fluoroscopic images were obtained at 5- or 10-min intervals until all markers had been excreted from the anal canal. For analysis, the GI transit times were subdivided into intestinal transit times (ITTs) and colon transit times (CTTs). RESULTS: The mean ITT was significantly longer in the loperamide groups than in the control group (p < 0.05). The mean ITT in loperamide group II (174.5 +/- 32.3) was significantly longer than in loperamide group I (133.2 +/- 24.2 minute) (p < 0.05). The mean CTT was significantly longer in loperamide group II than in the control group (p < 0.05). Also, no animal succumbed to death after the experimental procedure. CONCLUSION: The protocol for our study using radiopaque markers and barium is reproducible and minimally invasive in determining the GI transit time of the mouse model.

BACKGROUND: Although several molecular typing methods have been used to investigate C. albicans infections, there remains no "gold standard" method by which relatedness of C. albicans strains is determined. In this study, two DNA fingerprinting methods were compared for genotyping of clinical strains of C. albicans isolated from candidemic patients. MATERIALS AND METHODS: Twenty-nine strains of C. albicans isolated from various clinical specimens (14 from blood, 7 from catheter, 4 from respiratory tract secretion, and 4 from urine) of 14 candidemic patients were analyzed. Primer 1245 and 1246 were employed for IR PCR and Southern blot hybridization method was used for C2 fingerprinting, with Ca3 and C1 as primers, after the fragmentation of DNA with EcoR1 RESULTS: IR PCR method separated 29 isolates into 9 (1245 primer), 7 (1246 primer) and 14 (combination of two primers) types, whereas C1 fingerprinting identified 16 different types. By combining the IR PCR and C1 fingerprinting methods, total of 16 different genotypes were identified among 29 isolates from 14 patients, which is the same result obtained by the C1 fingerprinting only. Using both methods, blood and non-blood isolates from each patient produced identical genotypes for 10 patients and different genotypes for 1 patient. In three patients, isolates from blood and other site of each patient showed identical patterns by IR PCR fingerprinting, but appeared different (n=1) or similar (n=2) by C1 fingerprinting. Overall, for 87% (13/15) of patients, isolates collected from catheter (6 of 7 patients), urine (4 of 4 patients), or respiratory (3 of 4 patients) were identical or similar to the corresponding blood isolates. CONCLUSION: Our study shows that C1 fingerprinting method is more discriminatory than IR PCR for the molecular typing of C. albicans isolates. For the majority of patients, blood and other site isolates had identical or similar genotypes.

The inhibitory effects of Asparagus cochinchinensis against inflammatory response induced by lipopolysaccharide (LPS), substance P and phthalic anhydride (PA) treatment were recently reported for some cell lines and animal models. To evaluate the hepatotoxicity and nephrotoxicity of A. cochinchinensis toward the livers and kidneys of ICR mice, alterations in related markers including body weight, organ weight, urine composition, liver pathology and kidney pathology were analyzed in male and female ICR mice after oral administration of 150, 300 and 600 mg/kg body weight/day saponin-enriched extract of A. cochinchinensis (SEAC) for 14 days. The saponin, total flavonoid and total phenol levels were found to be 57.2, 88.5 and 102.1 mg/g in SEAC, respectively, and the scavenging activity of SEAC gradually increased in a dose-dependent manner. Moreover, body and organ weight, clinical phenotypes, urine parameters and mice mortality did not differ between the vehicle and SEAC treated group. Furthermore, no significant alterations were measured in alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), lactate dehydrogenase (LDH), blood urea nitrogen (BUN) and the serum creatinine (Cr) in the SEAC treated group relative to the vehicle treated group. Moreover, the specific pathological features induced by most toxic compounds were not observed upon liver and kidney histological analysis. Overall, the results of the present study suggest that SEAC does not induce any specific toxicity in the livers and kidneys of male and female ICR mice at doses of 600 mg/kg body weight/day.

BACKGROUND: The epidemiologic and clinical features of HIV infection/AIDS are different among various races, regions, and countries. To determine the epidemiologic and clinical characteristics of HIV infection in Korea, we analyzed and compared with that of other populations. METHODS: Medical records of 176 HIV-infected persons in Severance Hospital of Yonsei University College of Medicine and Hospital of Pusan University College of Medicine from year 1985 to 2000 were reviewed retrospectively. RESULTS: One hundred and seventy six patients were analyzed among which 156 (88.6%) were male and 20 (11.4%) were female with a male to female ratio of 7.8:1. At the time of diagnosis, the age distribution was 78 cases (44.3%) in the thirties, 44 cases (25.0%) in the twenties, and 35 cases (19.9%) in the fourties, and the mean age was 35.9+/-9.3. Heterosexual contact was the most frequent transmission route (92 cases, 52.3%), and 42 cases (23.9%) were transmitted by homosexual contact. At initial visit, asymptomatic HIV infection constituted 75 cases (42.6%), and AIDS 72 cases (40.9%). At initial visit, mean value of CD4+ lymphocyte counts was 252/mm3 and HIV RNA 226,035 copies/mm3. One hundred and twenty one of 176 patients developed 317 cases of opportunistic diseases. At the diagnosis of HIV-related opportunistic diseases, mean CD4+ lymphocyte count was 140/mm3 and mean HIV RNA 347,403 copies/mm3. Candidiasis (50 cases, 28.4%) was the most frequent opportunistic disease followed by pneumocystis carinii pneumonia (PCP) (37 cases, 21.0%), tuberculosis (29 cases, 16.5%), cytomegalovirus (CMV) infection (21 cases, 11.9%), HIV encephalopathy (9 cases, 5.1%), and herpes zoster (9 cases, 5.1%). There were 3 cases (1.7%) of malignant lymphoma and 2 cases (1.1%) of Kaposi's sarcoma. At the diagnosis of opportunistic diseases, mean CD4+ lymphocyte counts of patients with candidiasis was 71/mm3, PCP 63/mm3, and tuberculosis 142/mm3, and the mean HIV RNA level was 338,474 copies/mm3, 281,967 copies/mm3, and 817,012 copies/mm3 respectively. Among the 317 opportunistic diseases, AIDS-defining diseases were 150 cases (47.3%), of which PCP was 37 cases (24.7%), tuberculosis 29 cases (19.3%), CMV infection 21 cases (14.0%), HIV wasting syndrome 15 cases (10.0%), and esophageal candidiasis 14 cases (9.3%). The earliest AIDS-defining diseases to manifest in AIDS patients were tuberculosis (25 cases, 33.3%), followed by PCP (17 cases, 22.6%), esophageal candidiasis (14 cases, 18.7%), CMV infection (5 cases, 6.6%), and HIV wasting syndrome (4 cases, 5.3%). Thirty five (19.9%) of 176 patients were died. The common causes of death were tuberculosis (9 cases, 25.7%), PCP (9 cases, 25.7%), bacterial pneumonia (7 cases, 20.0%) and HIV encephalopathy (3 cases, 8.5%). CONCLUSION: The epidemiologic and clinical features of HIV infection/AIDS in Korea are different from that of developing countries such as Southeast Asia and Africa as well as from that of developed countries.
