Abstract

Parotid fluid corticosteroids, substantially comprised of cortisol and cortisone, were previously demonstrated to rise to far greater levels 4 hr after administration of ACTH than they did in the third trimester of pregnancy, although the plasma total corticosteroid concentrations were similar in these two states. It was therefore suggested that only nonproteinbound corticosteroid gains access to parotid fluid. In the present study parotid fluid cortisol and cortisone and plasma dialyzable cortisol concentrations have been measured in normal men before and 2 hr after 40 U ACTH, and, in another group, before and after 10 days of diethystilbestrol (5 mg daily). Total plasma cortisol rose from a mean of 6.3 to 17.9 mug/100 ml after ACTH and from 14.6 to 39.4 mg/100 ml after the estrogen. However parotid fluid cortisol plus cortisone rose from 0.8 to 2.6 mug/100 ml after ACTH and to only 2.2 after estrogen. This rise resembled that of the plasma dialyzable cortisol (control 0.4, ACTH 1.8, estrogen 1.2 mug/100 ml) rather than the increase in total plasma cortisol which was over twice as high after estrogen as after ACTH. Thus parotid fluid corticosteroids seem to be a good measure of nonprotein-bound corticosteroid, the cortisol available to the cell. The total amount of cortisol plus cortisone excreted is approximately constant, independent of parotid fluid flow rate. Cortisone exceeds cortisol in parotid fluid in the basal state, but after ACTH the situation is reversed.

  • Salivary cortisol and cortisone both show a close relationship to serum cortisol and serum free cortisol.

    “Salivary cortisol and cortisone both show a close relationship to serum cortisol and serum free cortisol [6,7].”

    From Bioavailability of Oral Hydrocortisone Corrected for Binding Proteins and Measured by LC-MS/MS Using Serum Cortisol and Salivary Cortisone (2018) · cites this paper as [7]

    The Results report close correlations between combined parotid-fluid cortisol plus cortisone and both plasma dialyzable (free) cortisol (r = 0.83) and total plasma cortisol (r = 0.75). They do not establish that salivary cortisol and cortisone each separately show those relationships, as the claim implies. No page number is available in our copy. (LLM, conf=0.86)

  • Salivary cortisone reflects serum free cortisol levels.

    “supporting the concept that salivary cortisone reflects serum free cortisol levels”

    From Bioavailability of Oral Hydrocortisone Corrected for Binding Proteins and Measured by LC-MS/MS Using Serum Cortisol and Salivary Cortisone (2018) · cites this paper as [7]

    The Results and Discussion report that parotid-fluid cortisol plus cortisone tracks dialyzable (free) plasma cortisol. The Results also show that parotid-fluid cortisone rises after ACTH, but the paper does not establish the stated relationship for salivary cortisone alone. Page numbers are unavailable in our copy.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
