Abstract
BIOLOGICAL standardization is the theme of the Bulletin of the Health Organisation (VI, 10, No. 2; 1942–43. Geneva (London: Allen and Unwin, League of Nations Publications Dept. 4s.)). The issue contains two articles on the biological standardization of heparin and on a provisional international standard for this substance, and other articles on standard preparations for the assay of the three gas-gangrene antitoxins, on the complexity of the tetanus toxin and on the variable interactions of tetanus toxins and antitoxins. The rest of the issue is occupied by seven articles from the Department of Biological Standards of the National Institute for Medical Research, London. The first of these deals with recent changes relating to international standards for certain sex hormones and for pituitary posterior lobe, due to exhaustion of stocks of the original preparations which had served as international standards for these hormones and the consequent need for their replacement by other samples. The other six articles deal with replacements of the substances of the international standards for the œstrus-producing hormone, for male hormones, progesterone and pituitary posterior lobe and with the international preparation of desiccated ox anterior pituitary gland and the international standard of prolactin.
