| scarlet fever antitoxin | Antitoxin specific for the erythrogenic toxin of strains of group A beta-haemolytic streptococci. (05 Mar 2000) |
| staphylococcus antitoxin | A preparation from native serum containing antitoxic globulins or their derivatives that specifically neutralise the lethal, skin-necrosing, and haemolytic properties of the alpha-toxin of Staphylococcus aureus. (05 Mar 2000) |
| normal antitoxin | Serum that is capable of neutralizing an equivalent quantity of a normal toxin solution. (05 Mar 2000) |
| despeciated antitoxin | An antitoxic serum treated in an appropriate manner to alter the species-specific protein, so that a person sensitised to the animal protein is not likely to have a serious reaction when the antitoxin is administered. (05 Mar 2000) |
| diphtheria antitoxin | An equine antitoxin against the toxin of corynebacterium diphtheriae, used for the treatment of diphtheria. It is to be differentiated from diphtheria toxoid which is used for the prevention of diphtheria. (12 Dec 1998) |
| dysentery antitoxin | Antitoxin specific for the neurotoxin of Shigella dysenteriae. (05 Mar 2000) |
| acoustic tetanus | Experimental tetanus induced by a faradic current, the speed of which is estimated by the pitch of the vibrations. (05 Mar 2000) |
| anodal closure tetanus | An obsolete term for a tetanic muscular contraction occurring during the time the circuit is closed, the current then running, while the positive pole is applied. (05 Mar 2000) |
| anodal duration tetanus | An obsolete term for the period of muscular contraction occurring at the anode when the electric circuit is closed. (05 Mar 2000) |
| anodal opening tetanus | An obsolete term for a tonic contraction in a muscle, to which the anode is applied, when the circuit is opened. (05 Mar 2000) |
| apyretic tetanus | 1. Hyperexcitability of nerves and muscles due to decrease in concentration of extracellular ionised calcium, which may be associated with such conditions as parathyroid hypofunction, vitamin D deficiency and alkalosis or result from ingestion of alkaline salts, it is characterised by carpopedal spasm, muscular twitching and cramps, laryngospasm with inspiratory stridor, hyperreflexia and choreiform movements. 2. Tetanus. (18 Nov 1997) |
| benign tetanus | A disorder marked by intermittent tonic muscular contractions of the extremities, especially the hands and feet (carpopedal spasm), accompanied by paresthesias and, when severe, by crowing respirations due to laryngospasm and seizures; results from hypocalcaemia, caused by various disorders, including gastrointestinal abnormalities. Synonym: intermittent cramp. (05 Mar 2000) |
| generalised tetanus | The most common type of tetanus, often with trismus as its initial manifestation; the muscles of the head, neck, trunk and limbs become persistently contracted, and then painful paroxysmal tonic contractions (tetanic seizures) are superimposed; the high mortality rate (50%) is due to asphyxia or cardiac failure. (05 Mar 2000) |
| cathodal closure tetanus | An obsolete term for a tetanic muscular contraction occurring during the time the circuit is closed, the current then running, while the negative pole is applied. (05 Mar 2000) |
