A 50-year old man who had acute type A aortic dissection, underwent prosthetic graft replacement of the ascending aorta. Intimal laceration of the ascending aorta was extending into the noncoronary Valsalva sinus just near the aortic annulus, but the competency of the aortic valve was preserved. Reconstruction of the noncoronary sinus was achieved by approximating intimal edge with Teflon felt reinforced buttress suture, then the ascending aorta was replaced by a Dacron prosthetic graft. His postoperative recovery was uneventful. 相似文献

The immunohistochemical distribution of CA19-9 in normal and tumor tissue of the kidney was investigated. CA19-9 was detected in the cytoplasm and apical surface of renal proximal tubules, distal tubules and uroepithelium of the renal pelvis. Eight of 28 renal cell carcinomas (29%) expressed CA19-9. CA19-9 was also detected in 2 cases of transitional cell carcinoma and 1 of 4 cases of Wilm's tumor, but not in angiomyolipoma. As the measurement of CA19-9 is widely used to detect gastrointestinal carcinoma, the expression of CA19-9 in normal and neoplastic kidney tissue might have some clinical significance. 相似文献

Sixty-one and 51-year-old males had progressive walk disturbance after cardiac operations at the intervals of 1 and 2 years. They had received blood transfusion at their operations. Physical examination revealed spastic paraparesis, sensory disturbance of the lower and rectobladder disorder. High titers of anti-Human T-lymphotrophic Virus type-I (HTLV-I) antibody were found in sera and CNF in both cases. They were diagnosed as HTLV-I associated myelopathy (HAM). Because they lived in Aichi Prefecture where the virus is non-epidemic, they were possibly infected through the blood transfusion at their operations. For prevention of HAM, the anti-HTLV-I antibody of all donor blood should be checked before transfusion. 相似文献

Electron microscopy and bacteriological culture revealed viable bacteria covered with a glycocalyx (biofilm) in choledochal
stones recovered from two patients with acute cholangitis. On the cut surface of the choledochal stones, the cholesterol stone
component was surrounded with a layer of brown pigment stone. In each case, bacterial culture of the choledochal stone recoveredPseudomonas aeruginosa. Since alginate is the main component of the glycocalyx produced byP. aeruginosa, serum IgM, IgG and IgA anti-alginate antibodies were measured in each patient. The present study is the first to demonstrate
acute and transient IgM seroconversion to alginate in cases of acute cholangitis. In one case, the elevation of anti-alginate
IgM preceded the elevation of anti-alginate IgG. The authors propose that the bacterial glycocalyx may play a significant
role in acute cholangitis. 相似文献

The accumulation of oxygen free radicals is reported to occur in the organs subjected to temporary ischemia followed by reperfusion, resulting in the fatal outcome of the animals. The effects of human SOD, a representative scavenger of oxygen free radicals, on the survival rates were investigated in the rats with temporary splanchnic ischemia. The temporary ischemia was induced by the occlusion of anterior mesenteric and celiac arteries for 30min under anesthesia. Prior and after treatment with 2mg/100g of human SOD, iv or sc, produced significant improvements in survival rates. Human SOD, cloned from human placenta DNA and expressed in microorganisms, has extreme homogeneity. The results suggest the possible introduction of human SOD into clinical field as an effective scavenger of oxygen free radicals.(Ogawa R, Bitoh H, Ohi Y: The effect of human SOD on the survival rate in rats with temporary splanchnic ischemia.

We have investigated the clinical significance of urinary tissue polypeptide antigen (TPA) as a tumor marker for urothelial cancers. Urinary TPA levels were determined by the immunoradiometric assay of Prolifigen TPA Kit "Daiichi"-II in 486 healthy controls and 1835 patients with various diseases including 526 with urothelial cancers and 140 with prostatic cancer. The mean value of urinary TPA was 199 +/- 213 (1SD)U/1 in 486 healthy controls. 95% of them having a level below 600 U/l. Therefore, 600 U/l was applied as a cut-off level. Positive rates of urothelial cancers and reactivated prostatic cancer were 57.6% (148 of 248 cases) and 45.5% (5 of 11 cases) respectively. On the other hand, the false positive rate of most urological benign diseases was only about 20% except for the acute stage of urinary tract infections and upper urinary tract stones with hydronephrosis. There was no significant difference in the positive rate between urinary TPA level and urinary cytology in urothelial cancers. The combination of both tests raised the positive rate to 73.1%. Therefore, urinary TPA may be useful in the monitoring of urothelial cancers, and the combination of urinary TPA and urinary cytology may increase the diagnostic accuracy. 相似文献

Inhibition ELISA assay was used to examine the cross-reaction of the polyclonal anti-desmosine antiserum produced in rabbit against molecules possessing a "pyridinium ring" as their core structure i.e. isodesmosine, pentasine, pyridinoline and 2'-deoxypyridinoline, highly purified with column chromatography, and structurally unrelated substances, i.e. cysteic acid, taurine and 2-aminopyridine (core structure of desmosine). No cross-reaction was observed to the pyridinoline, 2'-deoxypyridinoline possessing "pyridinium ring" and derived from collagen cross-links, structurally unrelated cysteic acid and taurine, nor core structure of 2-aminopyridine. The antiserum specifically recognized the molecules derived from the elastin cross-links. Using the ELISA assay system with antisera and amino acids analysis, 10 micrograms of desmosine were extracted from 1.0 mg of the hydrolysate of commercial elastin. 相似文献

Collapsin response mediating protein-2 (CRMP2) has been identified as an intracellular protein mediating Semaphorin3A (Sema3A), a repulsive guidance molecule. In this study, we demonstrate that cyclin-dependent kinase 5 (Cdk5) and glycogen synthase kinase 3beta (GSK3beta) plays a critical role in Sema3A signalling. In In vitro kinase assay, Cdk5 phosphorylated CRMP2 at Ser522, while GSK3beta did not induce any phosphorylation of CRMP2. Phosphorylation by GSK3beta was exclusively observed in Cdk5-phosphorylated CRMP2, but barely in CRMP2T509A. These results indicate that Cdk5 primarily phosphorylates CRMP2 at Ser522 and GSK3beta secondarily phosphorylates at Thr509. The dual-phosphorylated CRMP2, but not non-phosphorylated or single-phosphorylated CRMP2, is recognized with the antibody 3F4, which is highly reactive with the neurofibrillary tangles of Alzheimer's disease. 3F4 recognized the CRMP2 in the wild-type but not cdk5-/- mouse embryonic brain lysates. The phosphorylation of CRMP2 at Ser522 caused reduction of its affinity to tubulin. In dorsal root ganglion neurones, Sema3A stimulation enhanced the levels of the phosphorylated form of CRMP2 detected by 3F4. Over-expression of CRMP2 mutant substituting either Ser522 or Thr509 to Ala attenuates Sema3A-induced growth cone collapse response. These results suggest that the sequential phosphorylation of CRMP is an important process of Sema3A signalling and the same mechanism may have some relevance to the pathological aggregation of the microtubule-associated proteins. 相似文献
