Thrombospondin-4 TSP4 upregulates in the spinal cord following peripheral nerve injury and contributes to the development of neuropathic pain NP. We investigated the effects of cyanocobalamin alone or in combination with morphine on pain and the relationship between these effects and spinal TSP4 expression in neuropathic rats. NP was induced by chronic constriction injury CCI of the sciatic nerve.

Therefore, sibel ülker, it is accepted that blocking TSP4 expression has therapeutic potential in the targeted therapy of NP. There were no differences between the nociceptive thresholds of the control and sham groups sibel ülker any tests Fig. It was observed that the drug impaired relaxant responses to the substrate l -arginine as well, an observation suggesting that the function of NOS-III is impaired.

Nociceptive thresholds were detected by esthesiometer, analgesia meter, and plantar test, and TSP4 expression was assessed by western blotting and fluorescence immunohistochemistry. CCI decreased nociceptive thresholds in all tests and induced TSP4 expression on the 4th postoperative day. The decrease in nociceptive thresholds persisted except for the plantar test, and the increased TSP4 expression reversed on the 14th postoperative day.

There are contradictory reports regarding the persistence of thermal hyperalgesia in the CCI model of rat NP, i. Sapsford R. Trigeminal nerve injury-induced thrombospondin-4 up-regulation contributes to orofacial neuropathic pain states in a rat model. Nitric oxide: an overview Am J Surg Painful nerve injury upregulates thrombospondin-4 expression in dorsal root ganglia. There is very little information about the participation of TSP4 in the mechanisms of action of drugs or drug combinations in NP treatment. Ohara Y. Cromheecke M. Abstract Objective: Aprotinin, a non-specific serine protease inhibitor, reduces postoperative bleeding after coronary artery surgery. Venema R. In our NP groups treated with cyanocobalamin, morphine, and their combination, we detected a significant increase in TSP4 and GFAP immunoreactivities on the contralateral side, although not as much as on the ipsilateral side.

Krytzfeldt A. Indeed, it has been shown that aprotinin alters the ratio of 6-keto-prostaglandin F 1a :tromboxane B 2 and increases the production of von Willebrand factor in cultured human umbilical vein endothelial cells, leading to increased platelet aggregation with a tendency to plug particularly the small vessels [4,5]. Meanwhile, when concentration—response curves to PE in rings incubated with aprotinin plus l -NAME were compared to respective control curves, a profound increase in contractility and sensitivity was observed Fig.
