This year in the United States there has been considerable controversy about circumstantial evidence linking salicylates to the pathogenesis of Reye syndrome and, in particular, whether that evidence is sufficiently strong to justify action. After careful review both the Federal government and the American Academy of Pediatrics have warned physicians and parents of the possible risk of Reye syn...

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...

A rapid method based on UV spectrophotometry is described for simultaneous determination of salicylates and barbiturates in serum. While barbiturates have no absorbance above 280 m and extracted normal serum has insignificant absorbance, salicylate has a maximal absorbance peak at 296 mjh, which is proportional to concentration. The barbiturate concentration can be calculated from absorbance di...

The inhibition of cyclooxygenase does not fully account for the spectrum of activities of nonsteroidal antiinflammatory drugs. It is evident, indeed, that regulation of inflammatory cell function may contribute in explaining some of the effects of these drugs. Tissue recruitment of T cells plays a key role in the development of chronic inflammation. Therefore, the effects of salicylates on T-ce...

Between January 1985 and May 1986, following completion of a pilot study, a main study concerning the possible association between Reye's syndrome and salicylates was conducted. Twenty-seven patients with stage II or deeper Reye's syndrome whose diagnoses were confirmed by an expert panel and who had appropriate antecedent illnesses (chickenpox, respiratory illness, or gastrointestinal illness)...

Background—Salicylates may have direct vascular effects by mechanisms that are independent of platelet inhibition. Methods and Results—We investigated the effect of salicylates on vascular smooth muscle cell (SMC) proliferation in response to platelet-derived growth factor (PDGF) in vitro. Salicylate concentrations of 5 and 10 mmol/L inhibited serumor PDGF-induced SMC cell count and [H]thymidin...

The fresh produce industry is constantly growing, due to increasing consumer demand. The shelf-life of some fruit, however, is relatively short, limited by microbial contamination or visual, textural and nutritional quality loss. Thus, techniques for reducing undesired microbial contamination, spoilage and decay, as well as maintaining product’s visual, textural and nutritional quality are in h...

To determine salicylate content, 333 food items were analyzed. Foods were homogenized with 25% sodium hydroxide, allowed to stand overnight, acidified with concentrated hydrochloric acid, and then extracted with warm diethylether over 5 hours. The extract was dried and taken up in dilute sodium bicarbonate solution for analysis. Salicylic acid was separated by high performance liquid chromatogr...
