| toxaemia | 1. <microbiology> The condition resulting from the spread of bacterial products (toxins) by the bloodstream. 2. <biochemistry> A condition resulting from metabolic disturbances, for example toxaemia of pregnancy. Origin: Gr. Haima = blood (18 Nov 1997) |
|---|---|
| toxaemia of pregnancy | <obstetrics> A condition seen in the third trimester of pregnancy that is characterised by hypertension, swelling and the presence of protein in the urine. Synonym: preeclampsia. (12 Jan 1998) |
| toxaemic | Pertaining to, affected by, or manifesting the features of toxaemia. (05 Mar 2000) |
| toxaemic jaundice | <haematology> Haemolytic jaundice is a type of jaundice, where the skin takes on a yellowish hue, which occurs when red blood cells have been destroyed (by haemolysis). (09 Oct 1997) |
| toxaemic retinopathy of pregnancy | Sudden angiospasm of retinal arterioles, later followed by retinal vascular signs of advanced hypertensive retinopathy; vascular changes disappear rapidly after termination of the pregnancy. Synonym: eclamptic retinopathy, gravidic retinopathy. (05 Mar 2000) |
| toxalbumins | Phytotoxins that inhibit protein synthesis. (05 Mar 2000) |
| toxanaemia | Anaemia resulting from the effects of a haemolytic poison. Origin: G. Toxikon, poison, + anaemia (05 Mar 2000) |
| toxaphene | <chemical> A very complex, but reproducible mixture of at least 177 c10 polychloro derivatives, having an approximate overall empirical formula of c10-h10-cl8. It is used as an insecticide and may reasonably be anticipated to be a carcinogen: fourth annual report on carcinogens (ntp 85-002, 1985). Pharmacological action: carcinogens, insecticide, organochlorine. Chemical name: Toxaphene (12 Dec 1998) |
| toxascariasis | Infections with nematodes of the genus toxascaris. (12 Dec 1998) |
| toxascaris | An ascarid nematode found primarily in the small intestine of the larger felidae as well as dogs and cats. It differs from toxocara in that the larvae do not migrate through the lungs. It does occasionally produce visceral larva migrans (larva migrans, visceral) in man, although more rarely than does toxocara. (12 Dec 1998) |
| Toxascaris leonina | An ascarid nematode of the dog that differs from Toxocara in that the larvae do not migrate through the lungs; the entire developmental cycle occurs in the gut. This parasite has been found in humans in a few instances and is a cause of visceral larva migrans in children, though less frequently implicated than is Toxocara canis. Origin: G. Toxon, bow, + Ascaris (05 Mar 2000) |
| toxic | Pertaining to, due to or of the nature of a poison or toxin, manifesting the symptoms of severe infection. (18 Nov 1997) |
| toxic amaurosis | Blindness due to optic neuritis caused by methyl alcohol, lead, arsenic, quinine, or other poisons. (05 Mar 2000) |
| toxic amblyopia | Blindness due to optic neuritis caused by methyl alcohol, lead, arsenic, quinine, or other poisons. (05 Mar 2000) |
| toxic anaemia | Any anaemia resulting from the destructive effects of a chemical, metabolic poison, bacterial toxin, venom, and similar materials. (05 Mar 2000) |
