The idiopathic inflammatory bowel diseases, Crohn's disease (CD) and ulcerative colitis (UC), are chronic, frequently disabling diseases of the intestines. Segregation analyses, twin concordance, and ethnic differences in familial risks have established that CD and UC are complex, non-Mendelian, related genetic disorders. We performed a genome-wide screen(More)
HIV-associated sensory neuropathy (HIV-SN) is a frequent neurological complication of HIV infection and its treatment with some antiretroviral drugs. We review the pathogenesis of the viral- and drug-induced causes of the neuropathy, and its primary symptom, pain, based on evidence from in vivo and in vitro models of HIV-SN. Viral coat proteins mediate(More)
Mineralocorticoid hypertension was induced in male Wistar rats by the injection of desoxycorticosterone acetate (DOCA) in oily solution (2 X 5 mg/kg daily for 7 days) and of desoxycorticosterone trimethylacetate in a microcrystalline suspension (15 mg/kg every third day for 4 weeks). A 1% NaCl solution or demineralized water was given as drinking fluid.(More)
1. In corticosterone-induced hypertension in rats the activity of the peripheral sympathetic nervous system and its modulation by prostaglandins was studied. 2. Plasma concentrations of noradrenaline were reduced if compared with those in normotensive control rats. 3. The sensitivity of the isolated perfused hind-limb preparation to noradrenaline was(More)
We investigated the effects of intraperitoneal injections of a combination of two cyclo-oxygenase inhibitors, ibuprofen and paracetamol, with a weak opiate, codeine, on nociception in Sprague Dawley rats. Administration of paracetamol (11, 44, and 88 mg/kg), ibuprofen (8.75, 35, and 140 mg/kg) or codeine (0.44, 1.75, and 3.5mg/kg) alone caused a(More)
Hyperalgesia, a component of post-operative pain, is an enhanced responsiveness to painful challenges after the tissue damage caused by an incision. It is important to understand the mechanisms involved in the development of incisional pain, in order to treat the condition appropriately. The aim of this study was to develop a model of post-operative pain(More)
We have investigated whether long-term oral administration of the nucleoside reverse transcriptase inhibitor (NRTI) stavudine affects nociception in Sprague-Dawley rats, and whether any changes of nociception are accompanied by deterioration in activity and appetite. Stavudine (50 mg kg(-1)) was administered to rats orally once daily for six weeks in(More)
1. In rats with deoxycorticosterone acetate (DOCA) hypertension basal plasma concentrations of noradrenaline and adrenaline correspond to those of sham-treated controls. 2. In DOCA-treated rats frusemide caused a more pronounced increase in plasma noradrenaline than in control rats. This difference was not observed for adrenaline. 3. In the isolated(More)
Thirteen guinea pigs, sensitized to ovalbumin, were pretreated with either 1 ml alcoholic onion extract (=12% v/v ethanol) or 1 ml 12% ethanol solution (control) according to a randomized crossover protocol. Thirty minutes later the animals were challenged twice for 30 sec (n=5), respectively 60 sec (n=8), by the inhalation of ovalbumin (1 ml 1% ovalbumin(More)
Groups of 6–15 guinea pigs sensitized to ovalbumin were challenged by repeated inhalations of a constant histamine dose at time 0, 10, 20, 60 and 70 min. Bronchial obstruction was measured by whole body plethysmography. The degree of bronchial obstruction increased from one challenge to the other reaching maximal values after 70 min. This increase of(More)
