beta-2 adrenoceptors in blood vessels are one of the active factors that play a role in regulation of tissue blood flow. in diabetic angiopathy, responsiveness of these receptors is decreased, while that is increased in inflammation. according to these opposite effects, the aim of this study was to investigate the vasodilatory response of knee joint blood vessels to salbutamol (beta-2 adrenocep...

inflammatory  disease such as rheumatiod artheritis increase blood flow to joints.kaolin is one of substances injected into the joints in order to induce experimental acute joint inflammation the aim of this study was to determine the role played by nervous system in this model of acute in flammation.in the rabbit.evans blue technique was used to assess articular inflammation.the results indica...

Background: Curcumin is yellow pigment of tumeric, and, that is extracted from it lawsonia (2-hydroxy 1,4 naphtoquinon) is a natural product and it is extracted from henna. Ginger is a dried rhizomes gained from a plant called zingiber officinalea, which is extracted from the family of ginger. Material and Methods: This experimental study performed on adult male rats. Acute inflammatory edema ...

Inflammation is defined as the local response of living mammalian tissues to injury due to any agent. Inflammation involves 2 basic processes early inflammatory response later followed by healing. There are two types of inflammation, Acute and Chronic. Acute inflammation is of short duration and represents the early body reaction, resolves quickly and is usually followed by healing. Chronic inf...

These experiments examined the responses of articular blood vessels in the rabbit knee to induction of acute joint inflammation by intraarticular injection of 4% kaolin suspension. This produced an inflammatory response, which became evident about four hours after injection. Electrical stimulation of the nerve supply to the knee joint before induction of inflammation produced a biphasic respons...

OBJECTIVES To investigate the role of primary afferents, sympathetic postganglionic efferents and descending systems on the central control of peripheral inflammation. METHODS Acute inflammation was induced by intra-articular injection of kaolin and carrageenan into the knee joint cavity of the rat. Before the induction of the arthritis, a unilateral dorsal rhizotomy, a chemical (phentolamine...

  The dopaminergic system has different effects on the cardiovascular and immune systems. Since both vascular injuries and activation of the immune system are involved in joint inflammation, in the present study the role of dopaminergic receptors in knee joint inflammation was studied. Evans blue (75 µ g/kg) was used in order to observe changes in permeability which occurred during the process ...

objective(s):therapies with high levels of oxygen are commonly used in the management of critical care. however, prolonged exposure to hyperoxia can cause acute lung injury. although oxidative stress and inflammation are purported to play an important role in the pathogenesis of acute lung injury, the exact mechanisms are still less known in the hyperoxic acute lung injury (hali).   materials a...
