Sandwich Radioimmunometric Assay with Murine Monoclonal Antibody, NCC-ST-439, for Serological Diagnosis of Human Cancers 总被引:1,自引:1,他引:0

Sandwich radioimmunometric assay (RIA) for a new tumor-associated carbohydrate antigen defined by a monoclonal antibody (MoAb), NCC-ST-439, was developed and the antigen levels were determined in sera of normal donors, and patients with various malignant and non-malignant disorders. In normal donors, 97.0% (226/233) of sera were antigen-negative (less than 12 units/ml) except for 7 serum samples from young females. In patients with malignant disorders, 34.2% (82/240) were antigen-positive, in particular 64.0% (16/25) of patients with pancreatic carcinoma, 66.7% (16/24) of patients with recurrent colorectal carcinoma and 54,5% (6/11) of patients with recurrent breast carcinoma. In patients with non-malignant disorders, 6.0% (7/116) were antigen-positive. The positive rate in benign hepatobiliary disorders, including gallstones, hepatitis and liver cirrhosis, was especially low at 4.3% (1/23). We concluded that determination of serum NCC-ST-439 antigen would be useful in serodiagnosis of carcinoma patients. 相似文献

A patient with typical manifestations of von Hippel-Lindau diseaseis presented. In this 44 year-old man, cerebellar hemangioblastomawas found initially and he was operated upon at the age of 25.This was followed by retinal angiomas treated by cryocoagulationand, recently, by paresthesia of both legs and frequent shootingpains over the lower abdomen. A computed tomography disclosedmultiple small cysts of the pancreas, bilateral multicentricrenal carcinomas and a spinal angioma in the lumbar portion,confirmed by magnetic resonance imaging, and consistent withneurogenic manifestations. Multiple enucleations of the renalcell carcinomas were carried out, most of which were histologicallywell differentiated adenocarcinomas. There was no family cluster.Six months postoperative, the patient is doing well. 相似文献

Elevated morning home blood pressure (MHBP) has been reported to have a close relationship to cerebro-cardiovascular events and hypertensive target organ damages, and hence is regarded as a predictor of cardiovascular events. However, there is no evidence that lowering of MHBP can improve morbidity, mortality or target organ damage. In recent guidelines, angiotensin II type-1 receptor blockers (ARBs) are recommended as the first-choice drugs for antihypertensive therapy. Pharmacological characteristics differ among ARBs, and some are suggested to have greater efficacy in lowering MHBP than others. In preparation for the MUSCAT study, we surveyed both self-monitored MHBP and office blood pressure (OBP) in 1,234 patients with essential hypertension. Among them, 367 patients had diabetes mellitus (DM) and 229 suffered from chronic kidney disease (CKD). More than 64% (n=790) of patients had morning hypertension. In MUSCAT, we will investigate the different effects of four ARBs (losartan, candesartan, valsartan, and telmisartan) in patients with morning hypertension, with a focus on the drugs' MHBP-lowering efficiency. Secondly, we will evaluate the different actions of the four ARBs on cardiovascular surrogate markers, such as the brachial-ankle pulse wave velocity, high-sensitive C-reactive protein level, and urinary albumin excretion/creatinine ratio. Patients will be randomized into four arms, and given one of the four "sartans" once daily for 12 months. MHBPs and surrogate markers will be examined at baseline and after 1 year of follow-up. In the stratified analysis, we will determine the significance of MHBP reduction on cardiovascular risk management. 相似文献

We presented the ischemia/reperfusion (I/R) model which can evaluate changes in P-glycoprotein (P-gp) function induced by lipid peroxidation using surgical-sutures connected with the spring balance. The superior mesenteric artery and vein was occluded by hanging itself using surgical-sutures connected with the spring balance for 60 min (ischemia), followed by reperfusion by cutting of sutures. To determine the hanging force of blood vessel during ischemia, treatment at the hanging force of 50g load, 100g load and 150g load for 60 min was carried out and survival rate was evaluated. Although our 150g load group had some effect on survival, the survival was 100% in the case of 50g and 100g load groups. Thiobarbituric acid-reactive substance (TBA-RS) as an indicator of lipid peroxidation and P-gp expression level after I/R was increased and decreased in a load-dependent manner during ischemia, respectively. Also, the decrease in the level of mdr1a mRNA and function of P-gp by I/R depended on load during ischemia. The changes in TBA-RS, P-gp expression level and P-gp function observed in this study corresponded with our in vitro I/R model reported previously. In conclusion, it was shown that this in vivo I/R model can evaluate the function of P-gp through lipid peroxidation. 相似文献

Our objective is to clarify relationship between reversible cerebral vasoconstriction syndrome and administrating etanercept during puerperium. Several lines of evidence have suggested tumor necrosis factor (TNF) as a mediator of vascular dysfunction associated with estrogen deficiency. A 32-year-old woman resumed etanercept (25 mg/week), a TNF inhibitor, which had been discontinued during pregnancy, because of the deterioration of rheumatoid arthritis. She was admitted to our hospital with upper right quadrant blindness and mild right hemiparesis accompanied by pulsating left occipital pain, which had appeared 4 hours after restarting etanercept (25 mg/week). Magnetic resonance imaging and angiography revealed acute left hippocampal infarction with multiple segmental stenoses of the main intracranial arteries. Reversible cerebral vasoconstriction syndrome was diagnosed based on improvement of the multiple stenoses on magnetic resonance angiography on hospital day 17. A causal relationship was considered to exist between TNF inhibition by etanercept and multiple cerebral vasoconstrictions with brain infarct in this puerperant. 相似文献

A 71-year-old man who developed jaundice with a high-grade fever was admitted to our hospital. The episode was ascribed to cholecysto-choledocholithiasis. In the preoperative evaluation, a cavernous transformation of the portal vein and an early gastric cancer were found. The patient thereafter underwent an operation for those pathologies after the endoscopic removal of a choledochal stone; cholecystectomy, and a distal gastrectomy with regional lymph node dissection for gastric cancer. The proposed procedures of gastrectomy and cholecystectomy were completed without any major difficulty because no markedly enlarged collateral veins were found in the area where the regional lymph node dissection was carried out. Thanks to advances in imaging modalities, an asymptomatic cavernous transformation of the portal vein coinciding with gastric cancer such as that seen in the present case may be increasingly encountered in the future. The greatest caution, however, needs to be exerted at operation to minimize any unexpected bleeding and to avoid any interruption of the porto-portal shunts in such cases. Further, the reestablishment of the portal blood supply to the liver might be required in advanced cases of gastric cancer, where regional lymph node dissection may necessitate skeletonization of the hepatoduodenal ligament for curative purposes. 相似文献
