| POMC | Pro-Opio-Melano-Cortin |
| pro-opiomelanocortin | <chemical> A precursor protein, mw 30,000, synthesised mainly in the anterior pituitary gland but also found in the hypothalamus, brain, and several peripheral tissues. It incorporates the amino acid sequences of acth and beta-lipotropin. These two hormones, in turn, contain the biologically active peptides msh, corticotropin-like intermediate lobe peptide, alpha-lipotropin, endorphins, and methionine enkephalin. Chemical name: Opiomelanocortin, pro- (12 Dec 1998) |

| acidophilus milk | Milk inoculated with a culture of Bacillus acidophilus. (05 Mar 2000) |
| alkaline milk drip | A variable mixture of sodium bicarbonate in whole milk dripped into the stomach through a small oral or nasal tube to produce constant achlorhydria; used in the treatment of certain ulcers. (05 Mar 2000) |
| ampulla of milk duct | A circumscribed spindle-shaped dilation of the lactiferous duct just before it enters the nipple. In nursing mothers this dilatation stores a droplet of milk which is expressed by compression as the infant begins to suckle; this is thought to encourage continual suckling while the let-down reflex ensues. Synonym: sinus lactiferi, ampulla lactifera, ampulla of milk duct, lactiferous ampulla. (05 Mar 2000) |
| Bittner's milk factor | Member of the retrovirus subfamily Oncornavirinae, antigenically distinct from the murine leukaemia-sarcoma complex, that is associated with adenocarcinomatous tumours of the mammary gland, commonly latent in wild and laboratory mice and causing cancer only in genetically susceptible strains under certain hormonal influences. Synonym: Bittner agent, Bittner virus, Bittner's milk factor, mammary cancer virus of mice, milk factor, mouse mammary tumour virus. (05 Mar 2000) |
| buddeised milk | A method of milk sterilization; to the fresh milk, hydrogen peroxide is added in the proportion of 15 ml of a 3% solution to 1 liter of milk, and the mixture is heated to 51컊r 52캜 (124캟) for 3 hours, by which time the peroxide is decomposed and the nascent oxygen acts as an efficient germicide; the milk is then rapidly cooled and put into sealed bottles.

| vitamin D milk | Cow's milk to which vitamin D has been added, to contain 400 USP units of vitamin D per quart. (05 Mar 2000) |
| goat's milk anaemia | Nutritional anaemia in infants maintained chiefly with goat's milk, which is relatively poor in iron content. (05 Mar 2000) |
| certified milk | Cow's milk that does not have more than the maximal permissible limit of 10,000 bacteria per ml at any time prior to delivery to the consumer, and that must be cooled to 10캜 or less and maintained at that temperature until delivery. (05 Mar 2000) |
| certified pasteurised milk | Cow's milk in which the maximum permissible limit for bacteria should not be more than 10,000 bacteria per ml before pasteurization and not more than 500 bacteria per ml after pasteurization; it must be cooled to 7.2캜 or less and maintained at that temperature until delivery.
