| tetanus toxin | <protein> Neurotoxin released by Clostridium tetani, becomes active when peptide cleaved proteolytically to heavy (100 kD) and light (50 kD) chains held together by disulphide bond. Heavy chain binds to disialogangliosides (GD2 and GD1b) and part of the peptide (the amino terminal B fragment) forms a pore: light chain is a zinc endopeptidase that specifically attacks synaptobrevin, to block neurotransmitters.

| tetany | 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.

| tetany cataract | A cataract that develops in hypocalcaemia. (05 Mar 2000) |
| tetany of alkalosis | Tetany due to a loss of acid from the body or an increase in alkali, resulting in a reduction of ionised calcium in plasma and body fluids, e.g., hyperventilation tetany (loss of CO2), gastric tetany (loss of HCl by vomiting), or injection or ingestion of excessive amounts of sodium bicarbonate.
