in this study, the effects of separate and combined intraperitoneal (ip) injections of histidine and dexamethasone were investigated on local inflammation in rats. local inflammation was induced by subcutaneous (sc) injection of histamine (100 μl, 0.1%) in ventral surface of right hind paw. the thickness of paw was measured at 30 min before and 30, 60, 90, 120, 150 and 180 min after injection o...

Thiazolidinediones are commonly used anti-diabetic drugs. Owing to the anti-inflammatory action of TZDs as a result of there action on the PPAR gamma receptor and a proposed action on the prostaglandins, these drugs can be tried in the acute exacerbations of COPD that are also commonly found among diabetic patients. An experimental study of one week was carried out at animal house of Army Medic...

The aim of the present study was to investigate whether and by which mechanism; histamine can induce state-dependent retrieval of passive avoidance task. The pre-training or pre-test intracerebroventricular (i.c.v.) injection of histamine (20µg/mouse) impaired retrieval, when it was tested 24 h later. In the animals, which retrieval was impaired due to histamine pre-training administration, pre...

From November 1979 to May 1982, I had the "honor" of serving time at Evin political prison, Teheran Iran. Evin is the historical prison which has set the pace of revolution in the country. At Evin it was discovered that increased regular intake of water improved the clinical picture of peptic ulcer disease. One of the main components of this picture was pain of varying severity, sometimes very ...

Objective: Crocin, as an active constituent of saffron, has many biological functions including antioxidant and anti-inflammatory activities. The present study was aimed to investigate the effects of crocin and chlorpheniramine on local edema induced by histamine. Materials and Methods: Local edema was induced by subcutaneous injection of histamine (100 μl, 0.1%) in ventral surface of right hi...

objective: vanillosmopsis arborea baker (asteraceae) has high economic value from chapada to araripe and its bark essential oil is a potential source of alpha-bisabolol. the present study aimed to elucidate the antinociceptive and antipruritic properties of the essential oil of v. arborea baker (eova) in mice. materials and methods: the antinociceptive activity was assessed using the capsaicin,...

Introduction: Febrile seizures are the most common seizure disorder in childhood and its prevalence is estimated to be 2 to 5 percent. There is a relationship between the use of corticosteroids and seizures. This study investigated the effects of dexamethasone pretreatment on convulsive behavior caused by hyperthermia. Methods: In this study, 24 rats aged 19-20 days were divided into 3 group...

Several lines of evidence have indicated that many nuclei in the brain including preoptic nucleus, AV3V, subfornical organ, septal area and lateral hypothalamus are the targets of efferents from chemo-sensitive and pressure-sensitive systems. These areas may concern with regulation of fluid homeostasis. In the present study, intracerebroventricular injections were carried out in all experiments...
