Cresol is a well-known environmental pollutant, toluene metabolite, uremic toxicant and accidental poisoning product. Formocresol, a preparation of formalin and cresol, is also used as a root canal medicament and for pulpotomy of primary teeth. However, little is known about its effect on cardiovascular system. In this study, m-cresol inhibited the AA-induced platelet aggregation by 43-97% at concentrations ranging from 0.25 to 1 mM. Collagen-induced platelet aggregation was also inhibited by 0.25-1 mM of m-cresol by 47-98%. Accordingly, o-cresol (0.1-0.5 mM) also inhibited the AA-induced platelet aggregation by 46-96% and the collagen-induced platelet aggregation by 35-88% at concentrations of 0.1-1 mM. AA- and collagen-induced platelet thromboxane B(2) (TXB(2)) production was inhibited by even 0.1 mM of m-cresol with 88 and 54% of inhibition, respectively. The o-cresol (0.1 mM) also inhibited the AA- and collagen-induced platelet TXB(2) production with 91 and 97% respectively. Although m- and o-cresol (<1 mM) showed little effect on thrombin-induced platelet aggregation, they effectively inhibited the thrombin-induced platelet TXB(2) production. The m-cresol (2 and 5 mM) inhibited the COX-1 activity by 55-99%, but showed little effect on COX-2 enzyme activity. Moreover, o-cresol (0.5 and 1 mM) inhibited the COX-1 activity by 40-95%. COX-2 enzyme activity was inhibited by 68% at a concentration of 5 mM o-cresol. These results indicate that acute cresol-poisoning, direct root canal medication with formocresol or long-term occupational exposure to cresol and toluene may potentially suppress blood clot formation and lead to tissue hemorrhage via inhibition of platelet aggregation, TXB(2) production and COX enzyme activity.

... o-Cresol (in water) /was administered/ to rabbits by gavage. The extent of sulfate conjugation was determined before and after a 290 mg/kg o-Cresol dose. Twenty-two percent of the o-Cresol was excreted as the sulfate conjugate.

... o-Cresol (in NaHCO2) /was administered/ to rabbits by gavage. Urinary metabolites were evaluated after administration of 500 mg of o-Cresol. Fifteen percent of the dose was excreted as ethereal sulfate, 72% as ether glucuronide, 1% as free cresol, and about 3% as 2,5-dihydroxytoluene.

Cresols are slightly more corrosive /to the skin or eyes/ than phenol, but systemic effects may be a little milder because of slower absorption.

... A cross-sectional study on 100 workers indicated that the biological threshold for o-cresol:creatinine ratio reference value of <1 mg/g could presently be used as a reference for non-industrial human exposure while the <2 mg/g rate is for worker exposure in an industrial environment at a coal combustion plant.

Ten healthy men were exposed to approximately 200 ppm toluene for 4 hr. Urinary o-cresol concentration was 1.603 mg/L at the end of the exposure, 1.400 mg/L 4 hr after exposure, and 0.495 mg/l 20 hr after exposure.

In two workers admitted to hospital because of coma due to accidental occupational exposure to mixture of solvents, the level of toluene was respectively 823-1122 ug/L in blood & 53-38 ug/L in alveolar air on second day (36 hr after exposure). On fifth day (112 hr after exposure) the toluene level was 120-45 ug/L in blood & 3-1 ug/L in alveolar air. Urinary excretion of o-cresol, calculated as a toluene equivalent, was 0.8-0.9 mg on second day & 1.7 to 1.6 mg on third day. Urinary hippuric acid, as a toluene equivalent, was 1.7 to 1.4 g on second day & 1.3 to 0.7 g on third day.
