Proinflammatory agents trypsin and mast cell tryptase cleave and activate PAR2, which is expressed on sensory nerves to cause neurogenic inflammation. Transient receptor potential A1 (TRPA1) is an excitatory ion channel on primary sensory nerves of pain pathway. Here, we show that a functional interaction of PAR2 and TRPA1 in dorsal root ganglion (DRG)(More)
Bradykinin is an inflammatory mediator that plays a pivotal role in pain and hyperalgesia in inflamed tissues by exciting and/or sensitizing nociceptors. TRPA1 is an important component of the transduction machinery through which environmental irritants and endogenous proalgesic agents depolarize nociceptors to elicit inflammatory pain. Here, using(More)
Peripheral nerve injury causes neuropathic pain including mechanical allodynia and thermal hyperalgesia due to central and peripheral sensitization. Spontaneous ectopic discharges derived from dorsal root ganglion (DRG) neurons and from the sites of injury are a key factor in the initiation of this sensitization. Numerous studies have focused primarily on(More)
After >8,000 infections and >700 deaths worldwide, the pathogenesis of the new infectious disease, severe acute respiratory syndrome (SARS), remains poorly understood. We investigated 18 autopsies of patients who had suspected SARS; 8 cases were confirmed as SARS. We evaluated white blood cells from 22 confirmed SARS patients at various stages of the(More)
BACKGROUND Artemin, a member of the glial cell line-derived neurotrophic factor family, is known to have a variety of neuronal functions, and has been the subject of attention because it has interesting effects, including bi-directional results in modulation in neuropathic and inflammatory pain. It has been shown that the overexpression of artemin is(More)
BACKGROUND Resveratrol (3,5,4' - trihydroxy-trans-stilbene), a widely distributed natural stilbenoid, was proposed to account for the unique effects of red wine on life span and health. It has been reported to possess various biological and pharmacological activities, such as anti-oxidant, anti-inflammatory, and anti-carcinogenic effects. Here, using(More)
OBJECTIVE Hepatorenal syndrome is one of the serious complications of cirrhosis and closely associated with the increasing intra-abdominal pressure (IAP). The study aims to explore the potential mechanism of intra-abdominal hypertension in the development of hepatorenal syndrome in mouse models. METHODS Eighty male mice were randomly divided into model(More)
Darier's disease, also known as keratosis follicularis, is an uncommon autosomal dominant disorder that may also occur as a sporadic mutation. It is characterized by multiple eruptions of hyperkeratotic or crusted papules at seborrheic areas with histologic acantholysis and dyskeratosis. It usually begins in the first or second decade of life and is equally(More)
OBJECTIVES A significant percentage of confirmed severe acute respiratory syndrome (SARS) patients experienced gastrointestinal symptoms, and the viral sequence was detectable in the stool of most patients. At present, the knowledge of the pathology of the digestive system in SARS patients is limited. Because a resurgence of the SARS epidemic is constantly(More)
Between late March and June of 2008, an outbreak of hand, foot, and mouth disease caused by enterovirus 71 occurred in China. In this outbreak, more than 176,000 cases occurred, and at least 40 people died. However, there has been no description of the neuropathologic features of fatal enterovirus 71 infection cases during this outbreak. We report(More)
