The purpose of this study is to determine whether aspirin can reduce interleukin-1beta(IL-1beta) concentration and exert protective effects against heatstroke. The heatstroke rat model was established through exposing rat to a high ambient temperature (HAT, Ta 41 degrees C, relative humidity 65%) in a simulative HAT chamber to induce heatstroke. Three parts were performed in the present experim...
Acute liver failure is defined as rapid loss of liver function that patients without previously recognized liver disease sustain a liver damage. Acute liver failure due to non-exertional heatstroke has rarely been reported. We reported here an unusual case of heat stroke induced acute liver failure (ALF) after sauna. A 63 year old man without previously recognized liver and other systemic dise...
OBJECTIVE We investigated the effect of estrogen therapy on inflammatory responses, cardiovascular functions, and survival in a rat model of heatstroke. DESIGN Controlled, prospective study. SETTING Hospital medical research laboratory. SUBJECTS Sprague-Dawley rats (280-312 g of body weight, males and females). INTERVENTIONS Four major groups of anesthetized rats were designated for exp...
We aimed at investigating the effect of honokiol on heatstroke in an experimental rat model. Sprogue-Dawley rats were divided into 3 groups: normothermic diabetic rats treated with vehicle solution (NTDR+V), heatstroke-diabetic rats treated with vehicle (HSDR+V), and heatstroke rats treated with konokiol (0.5-5 mg/ml/kg) (HSDR+H). Sixty minutes before the start of heat stress, honokiol or vehic...
Abstract To reduce heatstroke cases, the Japanese government launched ‘Heatstroke Alert’ in 2020. In this initiative, an alert is issued when daily maximum wet bulb globe temperature (WBGT) expected to reach or exceed 33 °C. However, incidents at a of WBGT °C can vary by regions and age groups. study, we analyzed incidence all 47 prefectures Japan °C, considering addition, variations groups, al...
BACKGROUND In many parts of the world, including in China, extreme heat events or heat waves are likely to increase in intensity, frequency, and duration in light of climate change in the next decades. Risk perception and adaptation behaviors are two important components in reducing the health impacts of heat waves, but little is known about their relationships in China. This study aimed to exa...
BACKGROUND : We attempted to ascertain whether pre-existing inflammatory state [caused by exogenous administration of lipopolysaccharide (LPS)] exacerbated multiorgan dysfunction in experimental heatstroke. DESIGN : Immediately after the start of heat stress (42 degrees C), anesthetized rats were divided into 2 major groups and given 0.9% NaCl solution (10 mL/kg of body weight, intravenously)...
Heatstroke is characterized by excessive hyperthermia associated with systemic inflammatory responses, which leads to multiple organ failure, in which brain disorders predominate. This definition can be almost fulfilled by a mouse model of heatstroke used in the present study. Unanesthetized mice were exposed to whole body heating (41.2°C for 1 hour) and then returned to room temperature (26°C)...
We assess the effects of ipsapirone (a 5-HT1A receptor agonist), ketanserin (a 5-HT2A receptor antagonist), (-)-pindolol (a 5-HT1A receptor antagonist), and DOI (a 5-HT2A receptor agonist) on heatstroke in a rat model. Animals, under urethane anesthesia, were exposed to high ambient temperature of 42 degrees C until mean arterial pressure and local cerebral blood flow in the striatum began to d...
Elevated circulating cytokines are observed in heatstroke patients, suggesting a role for these substances in the pathophysiological responses of this syndrome. Typically, cytokines are determined at end-stage heatstroke such that changes throughout progression of the syndrome are poorly understood. We hypothesized that the cytokine milieu changes during heatstroke progression, correlating with...
