| serostatus | <investigation, microbiology> The condition of having or not having detectable antibodies to a microbe in the blood as a result of infection. One may have either a positive or negative serostatus. (28 May 1998) |

| serosynovial | Relating to serum and also synovia. (05 Mar 2000) |
| serosynovitis | Synovitis attended with a copious serous effusion. (05 Mar 2000) |
| serotaxis | Oedema of the skin induced by the application of a strong cutaneous irritant. Origin: sero-+ G. Taxis, an arranging (05 Mar 2000) |
| serotherapy | Treatment of an infectious disease by injection of an antitoxin or serum containing specific antibody. Synonym: serum therapy. (05 Mar 2000) |
| serotina | See: decidua. Origin: L. Fem. Of serotinus, late (05 Mar 2000) |
| serotine | <zoology> The European long-eared bat (Vesperugo serotinus). Origin: F. Serotine, fr. L. Serotinus that comes or happens late. Source: Websters Dictionary (01 Mar 1998) |
| serotinous | <biology> Appearing or blossoming later in the season than is customary with allied species. Origin: L. Serotinus, fr. Serus late. Source: Websters Dictionary (01 Mar 1998) |
| serotonergic | Related to the action of serotonin or its precursor l-tryptophan. Origin: serotonin + G. Ergon, work (05 Mar 2000) |
| serotonergic system | <anatomy, physiology> The system of nerve cells that uses serotonin as their neurotransmitter. (22 May 1998) |
| serotonin | <biochemistry, hormone> A neurotransmitter and hormone (176 kD), found in vertebrates, invertebrates and plants. It is synthesised from the amino acid tryptophan by enterochromaffin cells in the gut and bronchi. It is metabolised to 5-HIAA in the liver and then excreted in the urine. Serotonin is measured on a venipuncture specimen in cases of suspected carcinoid syndrome (where it will be elevated). The normal range is 101 to 283 ng/ml. Acronym: 5-HT (13 Nov 1997) |
| serotonin agents | Drugs used for their effects on serotonergic systems. Among these are drugs that affect serotonin receptors, the life cycle of serotonin, and the survival of serotonergic neurons. (12 Dec 1998) |
| serotonin agonists | Agents that have an affinity for serotonin receptors and are able to mimic the effects of serotonin by stimulating the physiologic activity at the cell receptors. These compounds are used as antidepressants, anxiolytics, and in the treatment of migraine. (12 Dec 1998) |
| serotonin antagonists | Drugs that bind to but do not activate serotonin receptors, thereby blocking the actions of serotonin or serotonin agonists. (12 Dec 1998) |
| serotonin uptake inhibitors | Compounds that specifically inhibit the reuptake of serotonin in the brain. This increases the serotonin concentration in the synaptic cleft which then activates serotonin receptors to a greater extent. These agents have been used in treatment of depression, panic disorder, obsessive-compulsive behaviour, and alcoholism, as analgesics, and to treat obesity and bulimia. Many of the adrenergic uptake inhibitors also inhibit serotonin uptake; they are not included here. (12 Dec 1998) |
