We experienced a congenital complete atrioventricular block infant who was born from a Ro/SS-A antibody positive mother. Ro/SS-A antibody was also found in this baby which was presumed to be mediated by the maternal placenta. Temporary cardiac pacing was required at birth and pacemaker implantation was performed at 9 months. At 11 months of age, the baby fell into shock and experienced multiple organ failure because of diabetes mellitus-induced coma. The association between congenital complete heart block and the Ro/SS-A antibody is well known. However, the accompaniment of insulin-dependent diabetes mellitus has not been reported previously. As the Ro/SS-A antigen appears in the cytoplasm of many tissues, the possibility of an association between Ro/SS-A antibody and diabetes mellitus is difficult to deny. We report this rare case to draw attention to the possibility that babies who are born from an Ro/SS-A antibody positive mother may develop diabetes mellitus as well as congenital complete heart block. 相似文献

Abstract: Pulmonary surfactant (PS) is a mixture of several lipids (mainly phosphatidylcholine; PC) and four apoproteins (A, B, C and D). The classical hypothesis of PS transport suggests that PS is synthesized in the endoplasmic reticulum and transported to the lamellar body (LB) via the Golgi apparatus. However, recent studies have raised questions regarding this single route. This study examined, independently, the intracellular trafficking route of three different components of PS, that is, PC, SP-A and SP-B. Alveolar type II cells were isolated from Sprague–Dawley rats or Japanese white rabbits. The cells were cultured with either [3 H]choline or [35 S]methionine/cysteine with or without brefeldin A, which disassembles the Golgi apparatus. LB was purified from disintegrated cells with sucrose density gradient centrifugation. [3 H]PC was extracted from radiolabeled media, cells, and the LB fraction with Bligh–Dyer's method. [35 S]SP-A or [35 S]SP-B was immunoprecipitated from each sample with a specific antibody. [3 H]PC was transported and stored to the LB via a Golgi-independent pathway. [35 S]SP-A was transported to the Golgi apparatus, underwent glycosylation, and was then constitutively secreted. The secreted [35 S]SP-A was re-uptaken into the LB. [35 S]SP-B was transported and stored to the LB via the Golgi-dependent pathway. These results indicate that, rather than a single route, surfactant components take different pathways to reside in the LB. These different pathways may reflect the different nature and role of each surfactant component such as surface tension-lowering activity and innate host defense. 相似文献

In 25 patients with hGH deficiency, who had been treated long-term with hGH, the mode of hGH administration was switched from the conventional method (0.3–0.5 IU/kg/week, in two or three divided doses, intramuscularly) to daily subcutaneous injection at 1900–2100 hours with a dose of 0.46 ± 0.07 IU/kg/week (equivalent to 14.7 ± 2.0 IU/m2 /week). After 1–3 months of this new mode of hGH administration, blood and urine were sampled at 0900 hours after overnight fasting. Blood glucose, plasma insulin, plasma IGF-1 and plasma total IGF (after extraction) were analysed in blood samples. IGF-1 and hGH were measured in urine samples. These measurements indicated that the dose studied was close to a replacement one, but might be slightly higher than the exact replacement dose. 相似文献

Abstract: The long-term effect of percutaneous transhepatic choledochoscopic YAG laser therapy for malignant biliary tract obstruction was evaluated. Ten consecutive patients underwent laser therapy to alleviate the obstruction. All patients were followed up for 8 months or more (range: 8–33 month, average: 15). Cholangiography was performed when re-elevation of the alkaline phosphatase level was observed during the regular checkup. Choledochoscopy was performed when any sign of recurrence was observed on cholangiography. Sufficient re-opening of the bile duct was obtained in every case, without complications. Indwelling of the internal drainage tube was perfomed in 5 patients, the remaining 5 having “tube free” internal drainage. Five patients showed no rise in alkaline phosphatase levels during their 8- to-13 month follow-up period. Re-elevation of the alkaline phosphatase level was observed 9 times in 5 patients, mostly from internal drainage tube occlusion. The cholangiogram performed on each occasion revealed a patent bile duct without any sign of recurrence (6/9), slight narrowing (2/9) or tumorous obstruction (1/9). Cholangitis was complicated 6 times in 3 patients, mostly from internal drainage tube occlusion. Choledochoscopy was performed in the 3 patients suspected of tumor recurrence on cholangiogram. In 2 of them, no signs of recurrence were noted endoscopically or histologically, but the tumor was revealed to have recurred only at the part previously treated, in the remaining. Thus, choledochoscopic I'AG laser therapy can locally control the malignant biliary tract obstruction for a long period of time. “tube free” internal drainage may serve as a means to prevent cholangitis, which is one of the complications frequently occurring with conventional stent therapy. 相似文献

Abstract: We describe a 56-year-old woman with congenital hepatic fibrosis. Blood tests and liver scanning with Tc-99m-labelled galactosyl human serum albumin revealed mild liver dysfunction. Per-rectal portal scintigraphy with iodine-123 iodoamphetamine showed severe abnormalities in the portal circulation, and the portal pressure measured during percutaneous transhepatic portography was high (350 mmH2O). Idiopathic portal hypertension was suspected. Laparoscopy disclosed diffuse, intense dendritic white markings around the liver. Congenital hepatic fibrosis was confirmed on histologic examination of a biopsy specimen obtained during laparoscopy. In summary, we report a rare and relatively elderly case of CHF, in which laparoscopy was useful in the diagnosis. (Dig Endosc 1999; 11: 174–178) 相似文献

AP-811 is a derivative of the Phe8-Ile15 region of atrial natriuretic peptide (ANP) and is one of the smallest linear ligands for ANP receptors. The binding and agonist activities of AP-811 have been compared with those of other ANP analogs for the ANP-A and ANP-C receptors. AP–811 binds with a high binding affinity to and is a strong agonist for the ANP-C receptor, indicating that the binding and agonist sites for this receptor are the same or near each other in the ANP sequence. In contrast, AP-811 showed no agonistic effect for the ANP-A receptor, although it could bind to this receptor. Comparing the biological activities of AP-811 with those of other ANP analogs, we propose that the binding and agonist sites for the ANP-A receptor may consist of separate regions of ANP. In conclusion, AP-811 is the smallest C-receptor-selective agonist. 相似文献

We report a case of mucinous adenocarcinoma of the renal pelvis associated with bladder carcinoma in situ (CIS). Transitional cell carcinoma (TCC) of the renal pelvis and CIS were also observed adjacent to the adenocarcinoma. Immunohistochemical assessment of the pelvic adenocarcinoma revealed positive expressions for mucin, epithelial membrane antigen, cytokeratin 7, cytokeratin 19 and carcinoembryonal antigen, but not vimentin or chromogranin. Based on the histopathological examinations, the adenocarcinoma of the renal pelvis in the present case may have a similar biological nature to conventional TCC and probably originated by development of pre-existing TCC of the renal pelvis. 相似文献

Abstract Event-related potentials (ERP) were recorded during auditory oddball tasks for a patient prior to and soon after left anterior temporal lobectomy. The N100 amplitude decreased bilaterally although the latency did not change after the lobectomy. The P300 amplitude decreased in the left hemisphere at 1 and 2 weeks after surgery, then recovered to the pre-operative level at 4 weeks. These findings suggest that the medial temporal structure participates in the generating system of P300. 相似文献

A single oral dose of 150 mg levamisole was administered to five healthy adults. Circulating Fc(IgG) receptor-bearing T cells (T gamma cells) increased for 5 days after levamisole intake, but total E rosette-forming cells showed no significant alterations. The generation of immunoglobulin-producing cells in the peripheral blood lymphocytes (PBL), which was induced in the in vitro pokeweed mitogen (PWM)-stimulated cultures, was significantly suppressed for 5 days after levamisole administration. Suppressor T-cell activity on B-cell differentiation, which was induced by levamisole intake, was evaluated by co-culturing with allogeneic untreated adult PBL in the PWM system in six other volunteers. A seemingly dose-dependent suppression on B-cell differentiation was exerted by T cells isolated on day 3 of levamisole treatment, but not by T cells differentiation was exerted by T cells isolated on day 3 of levamisole treatment, but not by T cells which were isolated before or on day 14 of the experiment. When T cells were fractionated into two subsets with regard to the presence or absence of Fc(IgG) receptors, suppressor T-cell activity appeared to be generated by levamisole largely in T cells lacking Fc(IgG) receptors, but not in T gamma cells. 相似文献
