Neurotrophins function through high-affinity tyrosine kinase (Trk) receptors to promote growth and survival of cells in the injured nervous system. To investigate the role of Trk receptors in the adult nervous system, we examined TrkA, TrkB, and TrkC mRNA expression in spinal cord and brain after spinal contusion. At 1 day postinjury, all Trk receptor(More)
Dehydrated dogs inhibit secretion of vasopressin (VP) within minutes after drinking water, before plasma osmolality (pOsm) diminishes. In recent studies, we found that water ingestion by rats similarly inhibits VP and oxytocin (OT) secretion rapidly, before pOsm is diluted. Adult male rats were infused with 1 M NaCl (2 ml/h iv) for 240 min to stimulate VP(More)
Cerebral osmoreceptors mediate thirst and neurohypophyseal secretion stimulated by increases in the effective osmolality of plasma (P(osmol)). The present experiments determined whether an intragastric load of hypertonic saline (ig HS; 0.5 M NaCl, 4 ml) would potentiate these responses before induced increases in P(osmol) in the general circulation could be(More)
UNLABELLED In this study, we aimed to evaluate the antinociceptive interaction between intrathecally administered amiloride and morphine or clonidine. Using rats chronically implanted with lumbar intrathecal catheters, we examined the ability of intrathecal amiloride, morphine, clonidine, and mixtures of amiloride-morphine and amiloride-clonidine to alter(More)
BACKGROUND HIV-associated sensory neuropathy affects over 50% of HIV patients and is a common peripheral nerve complication of HIV infection and highly active antiretroviral therapy (HAART). Evidence shows that painful HIV sensory neuropathy is influenced by neuroinflammatory events that include the proinflammatory molecules, MAP Kinase, tumor necrosis(More)
The aims of this study were to evaluate the anti-inflammatory and analgesic effects of bufalin, a major component of "Chan-su." We used a carrageenan-induced paw edema model to assess the anti-inflammatory activity of this compound, and Western blot analysis detected NF- κ B signaling during this effect. The antinociceptive activities were evaluated by(More)
Previous studies have shown that preoperative anemia is correlated with the prognoses of various solid tumors. This study was performed to determine the effect of preoperative anemia on relapse and survival in patients with breast cancer. A total of 2960 patients with breast cancer who underwent surgery between 2002 and 2008 at the Sun Yat-sen University(More)
Human immunodeficiency virus (HIV) patients treated with nucleoside reverse transcriptase inhibitors (NRTIs), have been known to develop neuropathic pain. While there has been a major shift away from some neurotoxic NRTIs in current antiretroviral therapy, a large number of HIV patients alive today have previously received them, and many have developed(More)
Previous studies have shown that ulinastatin, an effective inhibitor of the inflammatory response in clinical applications, can attenuate hyperalgesia in rodents. However, the underlying mechanism remains unclear. In the present study, we first examined the change in the calcineurin level, which plays an important role in regulating cytokine release in the(More)
