Abstract: We investigated the endosonographic findings in 3 patients with Dieulafoy's lesion. The characteristic finding was an elliptical or tortuous anechoic lesion in the submucosal layer that extended to the outer side of the gastric wall. There were no intramural changes suggestive of deep ulcer beyond the Ul-2. An abnormally large submucosal vessel was observed within 4 cm of the site of bleeding. This vessel was present even in the remnant stomach of a patient who required emergency surgery because an attempt to treat massive bleeding with endoscopic hemostasis failed. These endosonographic findings suggest that Dieulafoy's lesion patients risk rebleeding due to shallow ulceration. 相似文献

Abstract It is well known that genetic factors contribute to the susceptibility for schizophrenia. Recent advances in the molecular genetics of schizophrenia strongly suggest several susceptibility genes (e.g. dysbindin, neuregulin-1, DISC1, COMT, G72, RGS4 and Akt1). We discuss the evidence and biology of these genes. As glutamate transmission is especially implicated in these genes, neurobiological basis of schizophrenia might be elucidated by investigation of functional interactions between susceptibility genes for schizophrenia and the glutamatergic system. 相似文献

Twenty-four community residing elderly people in need of care, who were registered with the municipal welfare center in Miyagi Prefecture, Japan, and their principal caregivers participated in the study. The principal caregivers completed a self-administered questionnaire involving their demographic status, provided data on their utilization of formal services and completed the Center for Epidemiologic Studies Depression Scale (CES-D). The health visitors examined the activities of daily living (ADL) and mental status of these 24 elderly individuals. More than half the caregivers appeared to be depressed. The non-depressed caregivers used significantly more services than the depressed caregivers even after the caregivers' age was statistically controlled. 相似文献

The effects of dilazep and K-7259, a dilazep derivative, on the haemolysis (as evidenced by release of haemoglobin) induced by palmitoyl-l -carnitine (PAL-CAR) or palmitoyl 1-α-lysophosphatidylcholine (PAL-LPC) have been determined in rat erythrocytes. At concentrations above the critical micelle concentration both PAL-CAR and PAL-LPC induced haemolysis; the concentrations of PAL-CAR and PAL-LPC producing 50% haemolysis were approximately 13 and 14 μm , respectively. The 50% haemolysis induced by PAL-CAR or PAL-LPC was attenuated by dilazep (1, 10 or 100 μm ) but not at the highest concentration used (1 mm ). K-7259 attenuated the 50% haemolysis induced by PAL-CAR or PAL-LPC at concentrations ranging from 1 μm to 1 mm . Similarly, dilazep (1 to 100 μm ) and K-7259 (1 μm to 1 mm ) significantly or insignificantly attenuated the 25% and 75% haemolysis induced by PAL-CAR or PAL-LPC. Neither dilazep nor K-7259 affected micelle formation by PAL-CAR or PAL-LPC, nor, at concentrations of 1 and 10 μm , did they attenuate the haemolysis induced by osmotic imbalance (hypotonic haemolysis). These results suggest that both dilazep and K-7259 protect the erythrocyte membrane from the damage induced by PAL-CAR or PAL-LPC. The protective effects of dilazep and K-7259 are mediated by some mechanism other than prevention of micelle formation or protection of the erythrocyte membrane against osmotic imbalance. 相似文献

The prognosis in 52 patients with juvenile rheumatoid arthritis (JRA) was studied. There were 35 cases of systemic onset, 12 of polyarticular onset and 5 of pauciarticular onset. Thirteen systemic cases developed a polycyclic course with chronic polyarthritis. Many monocyclic JRA in systemic cases subsided within 1 year. There were no instances of polyarticular cases or pauciarticular cases that shifted to other type. However, there were many cases with a long active polyarticular JRA and with remission at an early stage in the pauciarticular type. The stage and class were I or II in 90% of cases with a good prognosis for the joints, but there were some serious cases. Transient carditis or iritis which developed at an early stage subsided later. The intractable systemic cases had drug-induced complications. The cases with steroid-induced complications tended to be chronic. One death in a systemic case was caused by hepatic failure. 相似文献

PURPOSE: We analyzed the presentation, treatment and survival of 4 children with renal cell carcinoma. MATERIALS AND METHODS: We retrospectively reviewed the pathological and hospital records of 4 Japanese children diagnosed with renal cell carcinoma at our hospital from 1970 to 1998. RESULTS: In the 1 boy and 3 girls with an average age of 8 years 7 months at diagnosis the most common presenting complaints were gross hematuria in 75% and a palpable abdominal mass in 50%. Computerized tomography revealed characteristic calcification within the tumor in 3 of the 4 patients (75%). In the remaining case the lesion had high density areas with microcalcification, as confirmed by histopathological study. In 2 patients with regional lymph node metastasis calcification was also observed in the metastatic lesions. Disease was stages I to III in 1, 1 and 2 patients, respectively. All patients underwent transabdominal nephrectomy with regional lymphadenectomy. One patient with stage I disease had multiple metastases 15 months later and died of disease 55 months postoperatively. However, the remaining 3 patients received adjuvant interferon therapy and they are without evidence of recurrence a mean of 51.3 months postoperatively. CONCLUSIONS: Calcification within the tumor and/or metastatic lesions or high density areas in the tumor on screening computerized tomography are characteristic findings suggestive of pediatric renal cell carcinoma. Adjuvant therapy with interferon may provide some benefit in select pediatric patients. Further studies of a larger number of pediatric renal cell carcinoma cases may be necessary to establish the optimal diagnostic and therapeutic regimen. 相似文献

The synthetic alpha-human atrial natriuretic polypeptide (alpha-hANP) was infused into six normotensive, euvolaemic, healthy volunteers to examine the effect on the plasma arginine vasopressin (AVP) concentration. The intravenous administration of alpha-hANP (0.1 microgram/kg/min, 20 min) led to a remarkable reduction in mean blood pressure (-10 mmHg, P less than 0.05), and there was an increase in pulse rate (+10 bpm, P less than 0.05), in each subject. The urinary volume, sodium excretion and cyclic 3',5'-guanosine monophosphate (cyclic-GMP) excretion were increased to 3.5 (P less than 0.05), 2.5 (P less than 0.05) eight-fold (P less than 0.01), respectively, during the alpha-hANP infusion. The dose and duration of the synthetic alpha-hANP in the present study was sufficient to induce these cardiovascular and renal effects. The plasma AVP concentrations decreased from 0.39 +/- 0.09 pg/ml to the undetectable level during the alpha-hANP administration. After infusion, the plasma concentrations of the AVP promptly returned to preinfusion levels (0.46 +/- 0.14 pg/ml). However, there was no significant change in plasma AVP concentration during placebo infusion. The marked suppression in plasma AVP concentration may account for the remarkable diuresis, in addition of the direct renal effects of the synthetic alpha-hANP. 相似文献
