| deficiency, zinc | Deficiency of zinc is associated with short stature, anaemia, increased pigmentation of skin (hyperpigmentation), enlarged liver and spleen (hepatosplenomegaly), impaired gonadal function (hypogonadism), impaired wound healing, and immune deficiency. (For a genetic disorder that impairs zinc uptake, please see Acrodermatitis enteropathica). According to the National Academy of Sciences, the Recommended Dietary Allowances of zinc are 12 milligrams per day for women and 10 milligrams per day for men. Food sources of zinc include meat including liver, eggs, seafood, nuts and cereal. (12 Dec 1998) |
|---|---|
| insulin, protamine zinc | <chemical> A long-acting insulin with an approximate time of onset of 7 hours and duration of action 36 hours, consisting of bovine or pork insulin reacted with zinc chloride and protamine to form a protein complex from which insulin is slowly released. Pharmacological action: hypoglycaemic agents. Chemical name: Insulin protamine zinc (12 Dec 1998) |
| insulin zinc suspension | A sterile buffered suspension with zinc chloride, containing 40 or 80 units per ml; the solid phase of the suspension consists of a mixture of 7 parts of crystalline insulin and 3 parts of amorphous insulin. Synonym: lente insulin. (05 Mar 2000) |
| extended insulin zinc suspension | A long-acting insulin suspension, obtained from beef, with an approximate time of onset of 7 hours and a duration of action of 36 hours. Synonym: crystalline insulin zinc suspension. (05 Mar 2000) |
| zinc | <chemistry, element> An essential trace element being an essential component of the active site of a variety of enzymes. Zinc has a high affinity for the side chains of cysteine and histidine. Zinc is present in tissues at levels of 0.1mM, but intracellular levels must be much lower. Abbreviation: Zn (18 Nov 1997) |
| zinc-65 | A radioactive zinc isotope that decays mainly by K-capture with a half-life of 243.8 days; used as a tracer in studies of zinc metabolism. (05 Mar 2000) |
| zinc acetate | <chemical> A salt produced by the reaction of zinc oxide with acetic acid. It is used as a pharmaceutic necessity for zinc-eugenol cement and also as an astringent, styptic, and formerly as an emetic. Pharmacological action: astringents, pharmaceutic aid. (12 Dec 1998) |
| zinc arsenate | <chemical> A toxic compound of zinc and arsenic which is used as an insecticide and to preserve timber from decay. (11 May 1997) |
| zinc caprylate | A topical antifungal compound. (05 Mar 2000) |
| zinc chloride | ZnCl2;formerly used as a caustic for the removal of cutaneous cancers, nevi, etc., and in weak solution in the treatment of gonorrhoea and conjunctivitis. Synonym: butter of zinc. (05 Mar 2000) |
| zinc colic | Colic resulting from chronic zinc poisoning. (05 Mar 2000) |
| zinc compounds | Inorganic compounds that contain zinc as an integral part of the molecule. (12 Dec 1998) |
| zinc D-Ala-D-Ala carboxypeptidase | <enzyme> Involved in last step of peptidoglycan synthesis; resistant to penicillin; see also record for d-alanyl-d-alanine serine peptidases Registry number: EC 3.4.17.14 Synonym: d-alanyl-d-alanine peptidase, zn(2+)g, zn(2+)g d-ala-d-ala peptidase, zn-ala-ala peptidase, zn(2+)g d-alanyl-d-alanine peptidase (26 Jun 1999) |
| zinc deficiency | : Deficiency of zinc is associated with short stature, anaemia, increased pigmentation of skin (hyperpigmentation), enlarged liver and spleen (hepatosplenomegaly), impaired gonadal function (hypogonadism), impaired wound healing, and immune deficiency. (for a genetic disorder that impairs zinc uptake, please see acrodermatitis enteropathica). According to the national academy of sciences, the recommended dietary allowances of zinc are 12 milligrams per day for women and 10 milligrams per day for men. Food sources of zinc include meat including liver, eggs, seafood, nuts and cereal. (12 Dec 1998) |
| zinc deficiency dermatitis and diarrhoea | A genetic disease called acrodermatitis enteropathica is characterised by the simultaneous occurrence of skin inflammation (dermatitis) and diarrhoea. The skin on the cheeks, elbows and knees and tissue about the mouth and anus are inflammed. There is also balding of the scalp, eyebrows and lashes, delayed wound healing and recurrent bacterial and fungal infections due to immune deficiency. The key laboratory finding is an abnormally low blood zinc level reflecting impaired zinc uptake. Oral treatment with zinc is curative. (12 Dec 1998) |
