    Notes: Summary To investigate the safety of the topical application of glutaraldehyde to the ankle and heel of man, the in vitro penetration of glutaraldehyde in a 10% aqueous solution through isolated human thin stratum corneum (chest and abdomen), isolated human epidermis (abdominal), and human thick stratum corneum (blister tops from the sole) was determined 1 h after application. Under these conditions, glutaraldehyde did not penetrate thick stratum corneum, while 2.8%–4.4% of the applied dose penetrated the isolated epdermis, and 3.3%–13.8% of the applied dose penetrated thin stratum corneum. An 8-week irritancy test was conducted by applying a 10% aqueous solution of glutaraldehyde to the ankle and heel area of 12 volunteers. Irritation and one case of sensitization resulted from glutaraldehyde application to areas of thin stratum corneum (anterior ankle) but not from applications to thick stratum corneum (medial, posterior, and lateral heel and posterior ankle), which may be a privileged site with respect to glutaraldehyde sensitivity.

    Notes: A procedure is described for the analysis of the estrogens equilin and estrone in human plasma following oral administration of conjugated estrogen preparations. After enzymatic hydrolysis of the sulfate conjugates, plasma proteins are precipitated with methanol and the estrogens extracted into ethyl acetate. Derivatization with the reagent flophemesylamine converts equilin and estrone into volatile pentafluorophenyldimethylsilyl ethers ideally suited to capillary gas chromatography-negative ion chemical ionization mass spectrometry. Using a 15 meter dimethyl silicone bonded phase fused silica capillary column separation of the estrone and equilin derivatives is achieved within 9 minutes. Selected ion monitoring of the intense negative molecular ions enables levels of 1 ng.ml-1 to be measured with coefficients of variation of 9.3 % and 14.2 % for estrone and equilin respectively. Plasma levels of the compounds are reported in two male volunteers up to 24 hours after dosing with 5 milligrams of Premarin™. (™ Ayerst Laboratories Inc., New York, USA.).
