| milk | 1. <physiology> A white fluid secreted by the mammary glands of female mammals for the nourishment of their young, consisting of minute globules of fat suspended in a solution of casein, albumin, milk sugar, and inorganic salts. "White as morne milk." 2. <botany> A kind of juice or sap, usually white in colour, found in certain plants; latex. See Latex. 3. An emulsion made by bruising seeds; as, the milk of almonds, produced by pounding almonds with sugar and water. 4. <zoology> The ripe, undischarged spat of an oyster. Condensed milk. See Condense, Milk crust, a special cell in the inner bark of a plant, or a series of cells, in which the milky juice is contained. See Latex. Rock milk. See Agaric mineral, under Agaric. Sugar of milk. The sugar characteristic of milk; a hard white crystalline slightly sweet substance obtained by evaporation of the whey of milk. It is used in pellets and powder as a vehicle for homeopathic medicines, and as an article of diet. See Lactose. Origin: AS. Meoluc, meoloc, meolc, milc; akin to OFries. Meloc, D. Melk, G.

| milk anaemia | A type of hypochromic microcytic anaemia, resulting from deficiency of iron, occurring in infants maintained on a milk diet for too long a time. (05 Mar 2000) |
| milk banks | Centres for acquiring, storing, and distributing human milk. (12 Dec 1998) |
| milk colic | Disease caused by the liberation of exotoxins of clostridium perfringens in the intestines of sheep, goats, cattle, foals, and piglets. Type b enterotoxaemia in lambs is lamb dysentery; type c enterotoxaemia in mature sheep produces "struck", and in calves, lambs and piglets it produces haemorrhagic enterotoxaemia; type d enterotoxaemia in sheep and goats is pulpy-kidney disease or overeating disease. (12 Dec 1998) |
| milk corpuscle | One of the fat droplets in milk. (05 Mar 2000) |
| milk crust | Seborrhoea of the scalp in an infant. Synonym: milk crust, milk scall. (05 Mar 2000) |
| milk cyst | A retention cyst in the mammary gland resulting from closure of a lactiferous duct. Synonym: milk cyst. (05 Mar 2000) |
| milk ducts | The ducts, numbering 15 or 20, which drain the lobes of the mammary gland; they open at the nipple. Synonym: ductus lactiferi, canalicular ducts, galactophore, galactophorous canals, galactophorous ducts, mamillary ducts, mammary ducts, milk ducts, tubuli galactophori, tubuli lactiferi. (05 Mar 2000) |
| milk ejection | Reflex in which tactile stimulation of nipples causes release of oxytocin which causes myoepithelial cells surrounding mammary alveoli to contract and expel the milk. Applies to humans and animals. (12 Dec 1998) |
| 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) |
| milk fever | A slight elevation of temperature following childbirth, said to be due to the establishment of the secretion of milk, but probably the same as absorption fever, an afebrile metabolic disease, occurring shortly after parturition in dairy cattle, characterised by hypocalcaemia and manifested by loss of consciousness and general paralysis. Synonym: parturient paralysis, parturient paresis. (05 Mar 2000) |
| milk gland | <anatomy> Milk producing gland of female mammals. An adapted sweat gland, it is made up of milk producing alveolar cells, surrounded by contractile myoepithelial cells, together with considerable numbers of fat cells. Milk production is hormonally controlled. (18 Nov 1997) |
| milk hypersensitivity | Allergic reaction to milk (usually cow's milk) or milk products. In infants the hypersensitivity is manifested by colic, vomiting, diarrhoea, rhinitis, wheezing, etc. Milk hypersensitivity should be differentiated from lactose intolerance, an intolerance to milk as a result of congenital deficiency of lactase. (12 Dec 1998) |
| milk leg | An extreme edematous swelling of the leg following childbirth, due to thrombosis of the iliofemoral veins. Synonym: leukophlegmasia dolens, milk leg, puerperal phlebitis, thrombotic phlegmasia, white leg. (05 Mar 2000) |
| milk let-down reflex | Release of milk from the breast following tactile stimulation of the nipple; the afferent path is postulated to exist from the nipple to the hypothalamus; the efferent limb is represented by the neurohypophysial release of oxytocin into the systemic circulation; contraction of myoepithelial elements within the breast, caused by oxytocin, moves milk into the collecting ducts and toward the nipple. Synonym: let-down reflex, milk let-down reflex. (05 Mar 2000) |
| 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. (05 Mar 2000) |
| 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. (05 Mar 2000) |
| perhydrase milk | Milk treated by the addition of hydrogen peroxide. See: Budde process. (05 Mar 2000) |
| metabolised vitamin D milk | Milk produced by feeding irradiated yeast to cows; standardised to contain not less than 400 USP units per quart. (05 Mar 2000) |
| modified milk | Cow's milk altered, by increasing the fat and reducing the amount of protein, to resemble human milk in composition. (05 Mar 2000) |
| pigeon's milk | A secretion formed by glands in the mucosa of the pigeon's crop with which the young are fed; it is increased under the influence of prolactin. Synonym: crop milk. (05 Mar 2000) |
