As pretreatment with intraperitoneal capsaicin (8-methyl-N-vanillyl-6-nonenamide, CAP), an agonist of the vanilloid receptor known as VR1 or transient receptor potential channel-vanilloid receptor subtype 1 (TRPV-1), has been shown to block the first phase of lipopolysaccharide (LPS) fever in rats,
Solus par aqua (SPA) is a traditional health care therapy. Warm SPA may enhance immunity and cellular defense to protect body against diseases. The present study investigated whether the warm SPA could confer protection to neurogenic inflammation in rats. The rats were immersed in water where the
Treatment of neonatal animals with capsaicin has previously been associated with long-lasting hyperthermia and severe cutaneous lesions. The present study analyzed the effects of capsaicin-induced hyperthermia on the occurrence of infectious disease and pruritic dermatitis in a rat model. Pregnant
OBJECTIVE
Peripheral afferents play an important role in fever. In the present study, we investigated the role of capsaicin-sensitive afferents in fever and cytokine responses during systemic (induced by intraperitoneal lipopolysaccharide, LPS) and local (induced by injection of Freund's incomplete
Following perineural capsaicin pretreatment of the main trunks of the abdominal vagus of rats, the first and the second phases of the polyphasic febrile response to intravenous lipopolysaccharide were unaltered, while the third phase of fever course (peak at 5 h) was attenuated. In rats desensitized
The fever elicited by 10 micrograms/kg intravenous E. coli endotoxin was significantly higher in capsaicin desensitized rats than in controls, but there was an upper limit to the rise in body temperature in both groups. Capsaicin desensitization permitted the participation of various heat producing
It has been demonstrated that capsaicin blocks lipopolysaccharide (LPS)-induced fever in mammals. In this study, we investigated TRPV1 (transient receptor potential ion channel of vanilloid subtype-1)-independent action of capsaicin on LPS-induced fever in chickens. The chicken is a valuable model
This study was performed to examine whether capsaicin, the main pungent ingredient of red peppers, exerts protective effects against testicular injuries induced by transient scrotal hyperthermia. Capsaicin (0.33 mg kg-1 ) was administered subcutaneously to mice one hour before heat stress (HS) in a
Transient receptor potential vanilloid 1 receptors (TRPV1) play a significant physiological role. The study of novel TRPV1 agonists and antagonists is essential. Here, we report on the characterization of polypeptide antagonists of TRPV1 based on in vitro and in vivo experiments. We evaluated the
Antagonists of the vanilloid receptor TRPV1 (transient receptor potential vanilloid type 1) have been reported to produce antihyperalgesic effects in animal models of pain. These antagonists, however, also caused concomitant hyperthermia in rodents, dogs, monkeys, and humans. Antagonist-induced
Vasodilatation in response to heat, the role of tail vasodilatation in thermolysis and the ability of the animals to use free water for evaporative cooling were studied in control and capsaicin-desensitized rats. 1) While vasodilatation in the tail began in the controls as soon as their temperatures
OBJECTIVE
Compound LASSBio-881 is an orally effective antinociceptive that binds to cannabinoid receptors and is active mainly on the neurogenic component of pain models. We investigated whether transient receptor potential vanilloid subfamily type 1 (TRPV1) channels are involved in the effects of
Capsaicin desensitization leads to behavioral changes, some of which are related to schizophrenia, but investigations into these effects have been scarce. The goal of this study was to characterize the consequences of juvenile capsaicin desensitization on different functions: acute and
In rats, fevers induced by moderate-to-high doses of intravenous lipopolysaccharide consist of three phases (phases 1, 2 and 3) with body temperature peaks at approximately 1, 2, and 5 h postinjection, respectively. In this study, the effects of bilateral truncal subdiaphragmatic vagotomy and
