Therapeutic effects of nandrolone decanoate, tibolone, lynestrenol and ethylestrenol on Sjögren's syndrome-like disorder in NZB/W mice.

Growth of mononuclear cell infiltration in submandibular glands is significantly inhibited by Org OD14 (tibolone), lynestrenol and ethylestrenol given orally to New Zealand Black/White (NZB/W) mice from 26 weeks of age onwards. In addition, the extent of already established mononuclear cell infiltrations is significantly inhibited and reduced by nandrolone decanoate injected from 43 weeks of age onwards. Tibolone and nandrolone decanoate are the most potent of the four drugs.

A rapid determination of brass composition and plating weight on brass-plated steel wire and cord by X-ray fluorescence spectrometry.

A rapid and simple means for determination of the brass composition and plating weight on brass-plated steel wire and cord is described. The sample preparation procedure is very simple; wires can be mounted as such, and cords can be mounted either as such or as unstranded single wires. The copper content of the brass and the plating weight are determined by measuring the intensities of the different elements by sequential X-ray fluorescence spectrometry (XRF).
