BACKGROUND: Noxious stimulation of the nasal mucosa may induce protective reflexes in the upper airway in rats. Previously, we have reported that nasal air-jet stimulation increases the activities of the laryngeal muscles in decerebrate cats; however, the neuronal mechanism of this phenomenon still is not clarified. METHODS: After the application of nasal air-jet stimulation for 2 hours, we investigated the distribution of Fos-positive cells (FPCs) throughout the medulla compared with sham-operated rats using Fos immunoreactivity. RESULTS: FPCs in the spinal trigeminal nucleus, the parvocellular reticular nucleus, and the nucleus of the solitary tract were more frequent than the sham-operated rats. CONCLUSION: These results suggest that the afferents induced by air-jet stimulation were conveyed to these FPCs and that some of these cells might participate in the augmentation of laryngeal muscle activities during nasal air-jet stimulation. 相似文献

Lansoprazole ameliorates intestinal mucosal damage induced by ischemia-reperfusion in rats 总被引:2,自引:0,他引:2

AIM:To investigate the protective effect of lansoprazoleon ischemia and reperfusion(I/R)-induced rat intestinalmucosal injury in vivo.METHODS:Intestinal damage was induced by clampingboth the superior mesenteric artery and the celiac trunkfor 30 rain followed by reperfusion in male Sprague-Dawleyrats.Lansoprazole was given to rats intraperitoneally 1 hbefore vascular clamping.RESULTS:Both the intraluminal hemoglobin and proteinlevels,as indices of mucosal damage,significantlyincreased in I/R-groups comparion with those of sham-operation groups.These increases in intraluminal hemoglobinand protein levels were significantly inhibited by the treatmentwith lansoprazole at a dose of 1 mg/kg.Small intestineexposed to I/R resulted in mucosal inflammation that wascharacterized by significant increases in thiobarbituric acid-reactive substances(TBARS),tissue-associatedmyeloperoxidase activity(MPO),and mucosal content of ratcytokine-induced neutrophil chemoattractant-1(CINC-1).These increases in TBARS,MPO activities and CINC-1 contentin the intestinal mucosa after I/R were all inhibited bypretreatment with lansoprazole at a dose of 1 mg/kg.Furthermore,the CINC-1 mRNA expression was increasedduring intestinal I/R,and this increase in mRNA expressionwas inhibited by treatment with lansoprazole.CONCLUSION:Lansoprazole inhibits lipid peroxidation andreduces development of intestinal mucosal inflammationinduced by I/R in rats,suggesting that lansoprazole mayhave a therapeutic potential for I/R injury. 相似文献

Reconstruction of jugular and portal blood flows using remodeled great saphenous vein grafts 总被引:1,自引:0,他引:1

Remodeled great saphenous vein grafts were used to reconstruct both jugular and portal veins. The great saphenous vein was split longitudinally and sutured side-to-side to construct a vessel twice the diameter and one half the length of the original vessel. This graft was used with good results for reconstruction of the jugular veins in a patient after a bilateral neck dissection for tongue cancer and for a portal vein in a patient after resection for cancer in the head of the pancreas. 相似文献

A case of middle aortic syndrome which was thought to be the thoracoabdominal type of Takayasu's disease was successfully treated with the branched graft bypass. Patient was a 23 year-old woman with hypertension and abdominal pain. The preoperative angiography revealed aortic stenosis from the celiac axis to the left renal artery. The operative procedures were as follows; patient was positioned in supine with her left shoulder and arm raised. Eighth intercostal thoracotomy and midline laparotomy was performed with the thoracoabdominal incision. The branched graft was made previously with woven Dacron (phi 18 mm) and three EPTFEs (phi 8mm). The woven Dacron of the graft was used for the bypass from the descending thoracic aorta to the infrarenal abdominal aorta, and the branched EPTFEs of the graft were used for the bypasses to the common hepatic artery, the superior mesenteric artery and the right renal artery in this order. The bypasses were placed along the anatomical courses in the retroperitoneal space. Postoperatively, the blood pressure dropped and the abdominal pain disappeared. The plasma renin activity decreased and the renal function improved. Two months after operation the bypasses were patent by the angiography and now six months after operation she has returned to her social life healthily. The approach to the aorta and its abdominal branches by thoracotomy and laparotomy and bypass with the three branched graft was useful for middle aortic syndrome. 相似文献

Using helical computed tomography (CT), we evaluated cystic pancreatic lesions in 11 patients and compared the imaging and
the histopathologic findings. Helical CT allowed us to assess the tumor vasculature. Contrastenhanced images showed satisfactory
details of the cysts, cyst walls, and intracystic structures. Helical CT is extremely useful for the evaluation of cystic
pancreatic lesions. 相似文献

A rare case of hemorrhagic infarction associated with carotid-cavernous fistula is reported. The patient was a 74-year-old female. CT scan showed hemorrhagic infarction of the left superior temporal gyrus, irregular vascular enhancement of the bilateral front-temporal lobe, and dilatation of the cavernous sinus. Left carotid angiogram revealed a high-flow left-sided CCF, cross filling to the right cavernous sinus, and intracavernous aneurysm. Bilateral front-temporal cortical veins were visualized early in the arterial phase. In this case, there was a direct shunt between the internal carotid artery and the cavernous sinus, and venous hypertension. Therefore urgent treatment using detachable balloon catheters was performed. Postoperative digital subtraction angiography revealed the disappearance of CCF. In conclusion, in CCF with cortical venous drainage there is a high possibility of developing hemorrhagic infarction. Only immediate detachable balloon occlusion can improve the outcome in elderly patients. 相似文献
