Effects of deltamethrin on hematological parameters and enzymatic activity in Ancistrus multispinis (Pisces, Teleostei)
Abstract Deltamethrin (DM) is a pyrethroid insecticide widely used in Brazilian crops and in pest-control programs because of its low environmental persistence and toxicity. It has been shown to… Expand

Involvement of bradykinin, cytokines, sympathetic amines and prostaglandins in formalin‐induced orofacial nociception in rats
This study characterises some of the mechanisms and mediators involved in the orofacial nociception triggered by injection of formalin into the upper lip of the rat, by assessing the influence of… Expand

Interleukin-8 induces fever by a prostaglandin-independent mechanism.
We have studied the mechanism by which interleukin-8 (IL-8) induces fever in rats. Intracerebroventricular injections of IL-8 (5.5-50 ng) evoked dose-dependent increases in body temperature, which… Expand

Antipyretic and anti-inflammatory properties of the ethanolic extract, dichloromethane fraction and costunolide from Magnolia ovata (Magnoliaceae).
AIM OF THE STUDY Magnolia ovata (A.St.-Hil.) Spreng (formerly Talauma ovata), known as "pinha-do-brejo" or "baguaçu", is a large tree widely distributed in Brazil. Its trunk bark has been used in… Expand

Peripheral kinin B1 and B2 receptor-operated mechanisms are implicated in neuropathic nociception induced by spinal nerve ligation in rats
The kinin system can contribute distinctly to the sensory changes associated with different models of nerve injury-induced neuropathic pain. This study examines the roles of kinin B(1) and B(2)… Expand

Effects of trophic exposure to diclofenac and dexamethasone on hematological parameters and immune response in freshwater fish.
The aim of the present study was to evaluate the effects of diclofenac and dexamethasone on hematological parameters and immune response in the fish species Hoplias malabaricus after trophic… Expand

Mechanisms operated by endothelin ETA and ETB receptors in the trigeminal ganglion contribute to orofacial thermal hyperalgesia induced by infraorbital nerve constriction in rats
Endothelins, acting through specific endothelin ET(A) and/or ET(B) receptors, participate in nociceptive processing in models of cancer, inflammatory and neuropathic pain. The present study… Expand

A comparative study of the antipyretic effects of indomethacin and dipyrone in rats
Abstract. Objective: Compare the antipyretic effects of dipyrone and indomethacin.¶Materials and methods: Fever was induced in rats by i.v. LPS or i.c.v. interleukins (IL), prostaglandins (PG),… Expand

Peripheral substance P and neurokinin-1 receptors have a role in inflammatory and neuropathic orofacial pain models
There is accumulating evidence that substance P released from peripheral sensory neurons participates in inflammatory and neuropathic pain. In this study it was investigated the ability of substance… Expand

Involvement of CRH in fever induced by a distinct pre-formed pyrogenic factor (PFPF)
Abstract:Objective: This study investigated the role of corticotrophin-releasing hormone (CRH) in mediating the fever induced by a novel pre-formed pyrogenic factor (PFPF), using a CRF antagonist in… Expand
