Different doses of aspirin, indomethacin, paracetamol, benorylate, and sodium salicylate were taken by four volunteers. The minimal dose that altered a platelet function test and the persistence of this alteration at different dose levels were studied. Minute doses of indomethacin (0.035 mg/kg) were effective but the effect of even a large single dose did not persist. A tenth of the therapeutic...

Proteasome inhibitors, antioxidants, salicylates, or glucocorticoids block the cytokine-induced expression of the endothelial cell adhesion molecules E-selectin, vascular cell adhesion molecule-1, and intercellular adhesion molecule-1. These pharmacological agents have been assumed to inhibit the expression of adhesion molecules primarily by blocking activation of the transcription factor NF-ka...

In Iranian traditional medicine, olive has been reported to have analgesic and anti-inflamatory effects. In the present study the anti-nociceptive and anti-inflamatory effects of olive fruit has been studied. In this study the methanolic and aqueous extract of the fruit with HER (Herbal to Extract Ratio) of 4.96% and 4.84% has been used and analgesic effect of this extract has been compared wit...

Self-motion of an oil droplet was investigated on a sodium dodecyl sulfate (SDS) aqueous phase. With an increase in the concentration of SDS, the nature of self-motion of a butyl salicylate (BS) droplet as the oil droplet was changed, i.e., no motion, reciprocation with a small amplitude, and reciprocation with a large amplitude, which was a value close to the half-length of the chamber. The in...

Staphylococcus epidermidis is a major cause of infections associated with indwelling medical devices. Biofilm production is an important virulence attribute in the pathogenesis of device-related infections. Therefore, elimination of these biofilms is an ideal treatment. Salicylate (5 mM) combined with 1 microg of vancomycin per ml inhibited biofilm formation by S. epidermidis (RP62A) by >or=99....

There have been numerous efforts to formulate insulin into an oral dosage form. The major problems involved with the oral administration of insulin are acidic and enzymatic decomposition by the gastric medium, and poor absorption in the small intestine due to its macromolecular structure. This study attempted to test the enhancing ability of two absorption enhancers, sodium glycocholate (Na-G...

A high dose of sodium salicylate temporarily induces tinnitus, mild hearing loss, and possibly hyperacusis in humans and other animals. Salicylate has well-established effects on cochlear function, primarily resulting in the moderate reduction of auditory input to the brain. Despite decreased peripheral sensitivity and output, salicylate induces a paradoxical enhancement of the sound-evoked fie...

In the current study, we explored whether chronic salicylate exposure could induce apoptosis in outer hair cells (OHCs) and spiral ganglion neurons (SGNs) of the cochlea. Guinea pig received sodium salicylate (400 mg/kg/d) or saline vehicle for 10 consecutive days. Programmed cell death (PCD) executioner was evaluated with immunohistochemistry detection of activated caspase-3. Apoptosis was exa...

Although salicylates are widely used as antipyretic agents, the mechanism by which they lower body temperature is controversial. It has been suggested that these compounds act at peripheral sites of inflammation, by suppressing release of endogenous pyrogen from leucocytes exposed to an inflammatory stimulus (1), or by suppressing synthesis and release of fever-inducing prostaglandins (2, 3). A...

In the preceding paper (1) it was pointed out that the administration of sodium salicylate to man induces a number of changes suggestive of thyrotoxicosis. There is an elevated basal metabolic rate (BMR), negative nitrogen balance, a fall in the cholesterol level of the hypothyroid subject, and an accelerated fractional disappearance rate of labeled thyroxine from the circulation. Paradoxically...
