A 73-year-old male with a history of diabetes mellitus was admitted to our hospital for acute renal failure. An ultrasonogram revealed bilateral hydronephrosis, which worsened despite insertion of a bladder catheter. Nephrostomy catheters were positioned bilaterally, and Candida albicans was found in the urine culture. The patient was successfully treated with intermittent direct irrigation and i.v. antifungal agent therapy. Since 1977, approximately 50 cases of fungus balls or fungal bezoars in the urinary tract have been reported, but the majority of these cases have been characterized by unilateral ureteral or bladder involvement. Herein, we report a case of acute renal failure as a result of bilateral ureteral obstruction by Candida albicans fungus balls. 相似文献

The proliferation sites and cellular kinetics of villous epithelial cells and M cells in the intestine of the adult chicken have never been clarified. In this study, we determined the proliferation sites in the chicken caecum using colchicine treatment and detection of proliferative cell nuclear antigen (PCNA). The cellular kinetics of these cells were also studied using bromodeoxyuridine (BrdU) as a tracer. Enterocytes in their mitotic period were observed along the entire length of the intestinal crypt of the caecum, with a denser distribution in the middle portion of the crypt, except for the caecal tonsil. The centres of distributions were at 49% of the distance from the bottom of the crypt in the base and 41% in the apex of the caecum. In the caecal tonsil, the centres of distributions were at 64% in the long type of crypt from the bottom of the crypt and at 44% in the short type of crypt. On the other hand, the PCNA-positive enterocytes were distributed more densely at the bottom of the crypt, except for the caecal tonsil. The centres of distributions were at 36% in the base from the bottom of the crypt, 37% in the body, and 34% in the apex. In the caecal tonsil, they were at 54% in the long type of crypt and 44% in the short type. The BrdU-labelled enterocytes reached to the basement of the intestinal villi in all caecal portions at 1 d after the BrdU administration. The leading edge of the labelled enterocytes disappeared from the villous tips at 4 d in the base and the body and 3 d in the apex. In the caecal tonsil, the BrdU-labelled microvillous epithelial cells and the M cells appeared near the orifice of the crypt at 1 d, and BrdU-labelled M cells were not observed in the crypt. Thereafter, almost all of these cells disappeared at 5 d from the follicle associated epithelium (FAE). These results suggest that M cells are transformed from their precursors within 1 d, and the turnover time for M cells occurs within 4 d after the cell division of the precursors. 相似文献

Okuno, A., Yano, K., Itoh, Y., Hashida, S., Ishikawa, E., Mohri, Z-I. and Murakami, M. (Department of Paediatrics, Asahikawa Medical College, Hokkaido; Medical College of Miyazaki, Kiyotake, Miyazaki; and Research and Development Division, Sumitomo Pharmaceuticals Co Ltd, Hyogo, Japan).

Urinary excretion of hGH was studied in children with short stature using a sensitive sandwich enzyme immunoassay technique. Urinary hGH excretion, in terms of hGH: creatinine ratio, showed excellent correlation with the mean and peak hGH values during physiological and pharmacological tests. It seems that the urinary hGH levels reflect serum hGH profiles during the urine collection period. A border zone for the lower limits of normal hGH levels in the urine was 7.5–13.4 ng/g creatinine for the physiological test at night (from 2000 hours to 0600 hours) and 17.4–35.0 ng/g creatinine for the pharmacological tests. Assessment of hGH secretory status by the urinary hGH levels showed good agreement with the serum hGH response. Measurement of urinary hGH could be used as a diagnostic test for impaired hGH secretion, and the multiple blood drawing required in physiological and pharmacological tests might be replaced by urine sampling. 相似文献

The case of a 13 year old boy with an inflammatory esophagogastric polyp and ulcerative colitis is described. Endoscopy revealed a typical polyp and gastric fold complex at the esophagogastric junction and a hiatal hernia. Histology of a biopsy specimen confirmed an inflammatory polyp covered by hyperplastic squamous and gastric foveolar epithelium. Continuous 24 hour esophageal manometry suggested gastroesophageal reflux, which may be related to the pathogenesis of the lesion. Follow-up endoscopy showed marked regression of the polyp with medication for reflux eosphagitis. This clinical entity is rare in childhood and adolescence, and the manifestations may not be readily recognized. Therefore, endoscopic biopsy is important in children with esophageal polyps. However, polypectomy is unnecessary except when malignancy is suspected or when symptoms persist. 相似文献

In a case with chronic pancreatitis and pseudocysts related to muscular cytochrome—c oxidase deficiency, endoscopic ultrasonography (EUS) was performed to morphologically examine the pancreas for features that may have been missed by abdominal computed tomography and pancreatography. Conventional abdominal sonography had failed to show valuable diagnostic information of chronic pancreatitis in this case. EUS demonstrated several new findings. Parenchymal atrophy was remarkable, especially in the pancreatic tail, and a dilated pancreatic main or branch duct was clearly found in the region. Moreover, pancreatic stones in the main duct were also distinctly proved. EUS may become a useful new diagnostic method in pediatric gastroenterology, especially when sufficient findings are not obtained by conventional imaging techniques. However, an ultrasonographic endoscope with a shorter rigid portion and smaller caliber should be developed for pediatric patients. 相似文献

An 8 year old girl with acute disseminated encephalomyelitis (ADEM) is described. Elevated serum antibody titers suggested recent Mycoplasma pneumoniae infection. T2-weighted image of magnetic resonance imaging (MRI) disclosed multiple lesions of high signal intensity in bilateral basal ganglia and thalami as well as in the white matter. Postcontrast T1-weighted image revealed an enhanced lesion in the deep white matter. She showed rapid clinical improvement in response to corticosteroid therapy. The lesions had disappeared completely on MRI performed 10 weeks after the onset. ADEM is believed to be a demyelinating disorder of probable autoimmune etiology. MRI findings in this case may support the hypothesis that the primary pathological event is vascular injury and demyelination occurs only as a secondary phenomenon. 相似文献

Leucocytes from patients with colorectal and other malignant and non-malignant gastrointestinal diseases as well as those from normal subjects were tested by the leucocyte migration inhibition test (LMIT), employing the method of Clausen, using five different allogenic 3M KCI soluble extracts of colorectal cancer tissue. The normal range of migration index (Ml) was found to be > 0.82 and > 1.20 by calculating the mean Ml ± 2SD of ten normal subjects with cancer extracts. Mis out of this range were considered to be pathological. In LMIT with a single tumour extract, a pathological Ml was found in 46% of 50 colorectal cancer patients, a significantly higher figure than found in the three other groups of patients (4% to 16%). In the panel mode of LMIT, that is, testing each blood sample with five different tumour extracts, 40/50 (80%) of patients with colorectal cancer were reactive, while 2/15 (13%) of gastric cancer patients showed a “positive” reaction; no positive reactivity was observed in the other two groups of patients. Thus “positive” reactivity was significantly commoner in patients with colorectal cancer than in patients belonging to the other groups. The frequency of “positive” reactivity was higher in patients with Dukes C carcinoma than in those with Dukes A or B carcinomas, though differences were not significant. In the follow-up study, marked depression of reactivity was seen 10 to 14 days after curative resection. In patients without recurrence, leucocyte migration was found to be in the normal range during the two to four weeks after surgery. “Positive” reactivity reappeared in patients with local recurrence. Thus the LMIT, particularly when tested by a panel mode, by demonstrating cell-mediated immunity against tumour-associated antigens of colorectal cancer, provides a method of monitoring colorectal cancer activity. 相似文献

A patient with urinary bladder pheochromocytoma and anotherpheo-chromocytoma in the para-aortic region is presented. Also,nine cases which have already been reported in Japan are reviewed. The following conclusions are made: bladder pheochromocytomacan appear at any age in either sex. The clinical triad consistingof hypertension, gross intermittent or transient painless hematuriaand micturitional attacks typical of pheochromocytoma are seenin most cases. Attention is called to such urinary bladder 相似文献

Human mercaptalbumin (HMA) and nonmercaptalbumin (HNA) could be separated by high-performance liquid chromatography (HPLC) at neutral pH. Using HPLC, the present authors found the nonmercapt-mercapt conversion (HNA ← HMA) during hemodialysis and the mercapt-nonmercapt conversion (HMA ← HNA) after hemodialysis in chronic renal failure, indicating HMA as the covalent carrier protein for sulfur-containing amino acids. 相似文献
