    “…OBJECTIVES: Endoscopic nasopharyngectomy (ENPG) is a promising way in treating recurrent nasopharyngeal carcinoma (rNPC), but sometimes may require therapeutic internal carotid artery (ICA) occlusion beforehand. Balloon test occlusion (BTO) is performed to evaluate cerebral ischemic tolerance for ICA sacrifice. …”

    “…Recently, extracranial internal carotid artery (eICA) arteriopathy has been reported, and a cross-sectional study showed that eICA-TAMVs ≥160 cm/s are significantly associated with eICA kinkings and stenosis. …”

    “…Preincubation of the SAN cells with L-nitro- arginine methyl ester (L-NAME; 0.2-1 mM), which inhibits NO synthase (NOS), abolished the CCh-induced attenuation of ICa(L) but had no effect on IK(ACh). Coincubation of cells with both L-NAME and the endogenous substrate of NOS, L-arginine (1 nM), restored the CCh- induced attenuation of ICa(L), indicating that L-NAME did not directly interfere with the muscarinic action of CCh on ICa(L). …”

    “…Both isoproterenol (ISO) and forskolin increased ICa dose dependently. After ICa had been enhanced maximally by ISO (10(-6) M), subsequent application of forskolin (50 microM) did not further increase ICa, suggesting that ISO and forskolin increase ICa via a common biochemical pathway, possibly by stimulation of adenylate cyclase. …”
