The latex of the wild growing plant Calotropis procera produces inflammation of the skin and mucous membranes upon accidental exposure. On local administration it elicits an intense inflammatory response due to the release of histamine and prostaglandins that is associated with hyperalgesia. In the present study we have evaluated the anti-inflammatory and antinociceptive activity of oxytocin an...
Formation of atelectasis is one mechanism of impaired gas exchange during general anaesthesia. We have studied manoeuvres to re-expand such atelectasis in 16 consecutive, anaesthetized adults with healthy lungs. In group 1 (10 patients), the lungs were inflated stepwise to an airway pressure (Paw) of 10, 20, 30 and 40 cm H2O. In group 2 (six patients), three repeated inflations up to Paw = 30 c...
The novel bicyclo thieno 1, 2, 3-triazines (BTT) namely BTT-1, BTT-2, BTT-3 and BTT-4 were evaluated for analgesic anti-inflammatory and antiarthritic activity. Analgesic and anti-inflammatory activity was evaluated using hot plate test , formalin induced paw licking test and formalin induced paw edema test respectively, complete fruend’s adjuvant (CFA) induced arthritis model was used for anti...
BACKGROUND We have proposed that nerve injury-specific loss of spinal tonic cholinergic inhibition may play a role in the analgesic effects of nicotinic acetylcholine receptor (nAChR) agonists on neuropathic pain. However, the tonic cholinergic inhibition of pain remains to be well characterized. RESULTS Here, we show that choline acetyltransferase (ChAT) signals were localized not only in ou...
Aims & Objectives: The present study consists in evaluation of the effects of the dipeptides Kyotorphin (Kyo) and D-Kyotorphin (D-Kyo) on nociception and plasma levels of adrenocorticotrophic hormone and corticosterone after 1 hour of heat stress in rats. Materials & Methods: Kyo and D-Kyo`s effects on nociception were evaluated by Paw pressure and Hot plate test after 1 hour of heat stress. Pl...
BACKGROUND Propofol can inhibit fatty acid amidohydrolase, the enzyme responsible for the metabolism of anandamide (an endocannabinoid). To study the potential antinociceptive effect of propofol, we administered different doses (0.005, 0.05, 0.5, 5, and 500 microg) of the anesthetic in the hind paw of animals to determine an ED50. To further investigate the mechanisms by which propofol produced...
We compared in a randomized fashion the hemodynamic effects of intravenous (IV) isosorbide dinitrate (ISDN) and nitroglycerine (NTG) in 45 patients with acute myocardial infarction and elevated pulmonary artery wedge pressure (Paw). Titration of ISDN dose to lower Paw greater than or equal to 25 percent resulted in a fall of this parameter from 32 +/- 8 to 24 +/- 5 mm Hg and was associated with...
Previous studies have shown that systemic administration of 6'-hydroxy-2',4'-dimethoxychalcone (flavokawin B, FKB) exerts significant peripheral and central antinociceptive effects in laboratory animals. However, the mechanisms underlying these peripheral and central antinociceptive effects have yet to be elucidated. Therefore, the objective of the present study was to evaluate the participatio...
The antihyperalgesic properties of the opiate antidiarrheal agent loperamide (ADL 2-1294) were investigated in a variety of inflammatory pain models in rodents. Loperamide exhibited potent affinity and selectivity for the cloned micro (Ki = 3 nM) compared with the delta (Ki = 48 nM) and kappa (Ki = 1156 nM) human opioid receptors. Loperamide potently stimulated [35S]guanosine-5'-O-(3-thio)triph...
The purpose of this study was to test the effect of high voltage stimulation (HVS) on edema reduction in the rat hindpaw. The animals were divided into a control group (n = 20) and a treated group (n = 20). The right hindpaw volume was measured, and then the animal's paw was traumatized. The animals in the treated group were treated with HVS at 24, 48, and 72 hours posttrauma. Paw volume measur...
