| human growth hormone | <endocrinology> A protein produced in the pituitary gland that stimulates the liver to produce somatomedins, which stimulate growth of bone and muscle. (09 Oct 1997) |

| receptors, pituitary hormone-regulating hormone | Cell surface receptors that bind the hypothalamic hormones regulating pituitary cell differentiation, proliferation, and hormone synthesis and release, including the pituitary-releasing and release-inhibiting hormones. The pituitary hormone-regulating hormones are also released by cells other than hypothalamic neurons, and their receptors also occur on non-pituitary cells, especially brain neurons, where their role is less well understood. Receptors for dopamine, which is a prolactin release-inhibiting hormone as well as a common neurotransmitter, are not included here. (12 Dec 1998) |
| hormones, hormone substitutes, and hormone antagonists | A collective grouping for both naturally occurring and synthetic hormones, substitutes, and antagonists. (12 Dec 1998) |
| follicle-stimulating hormone-releasing hormone | A decapeptide of hypothalamic origin capable of accelerating pituitary secretion of follitropin. Synonym: follicle-stimulating hormone-releasing factor, follicle-stimulating hormone-releasing hormone. Origin: follicle-stimulating hormone + L. Libero, to free, + -in (05 Mar 2000) |
| luteinizing hormone/follicle-stimulating hormone-releasing factor | gonadotrophin-releasing hormone |
| luteinizing hormone-releasing hormone | A hormone that controls sex hormones in men and women. Also called lhrh. (12 Dec 1998) |
| bone marrow suppression | <oncology, pharmacology> A side effect of many anticancer and antiviral drugs, including AZT. Bone marrow suppression leads to a decrease in white blood cells, red blood cells and platelets. Such reductions in turn result in anaemia, bacterial infections and spontaneous or excess bleeding. (09 Oct 1997) |
| nonsense suppression | Mutant tRNAs that read a chain termination codon as the signal for incorporation of a specific amino acid residue. (05 Mar 2000) |
| suppression | 1. The act of suppressing, or the state of being suppressed; repression; as, the suppression of a riot, insurrection, or tumult; the suppression of truth, of reports, of evidence, and the like. 2. <medicine> Complete stoppage of a natural secretion or excretion; as, suppression of urine; used in contradiction to retention, which signifies that the secretion or excretion is retained without expulsion. 3. Omission; as, the suppression of a word. Synonym: Overthrow, destruction, concealment, repression, detention, retention, obstruction. Origin: L. Suppressio: cf. F. Suppression.

| suppression amblyopia | The suppression of the central vision in one eye when the images from the two eyes are so different that they cannot be fused into one. This may be due to: 1) faulty image formation (sensory amblyopia); 2) a large difference in refraction between the two eyes (anisometropic amblyopia); or 3) the two eyes pointing in different directions (strabismic amblyopia). Most suppression amblyopia can be reversed if appropriately treated before age 6 years. Synonym: amblyopia ex anopsia. (05 Mar 2000) |
| suppression, genetic | The restoration of the wild-type phenotype in an organism possessing a mutationally altered genotype. The effects of the mutation may be suppressed by a second "suppressor" mutation on a different gene, by a suppressor mutation on the same gene but located at a distance from the site of the primary mutation, or by the presence of a cytoplasmic suppressor due to a change in non-chromosomal DNA. (12 Dec 1998) |
| immune suppression | Suppression of the immune response by some compound or agent. (05 Mar 2000) |
| intergenic suppression | The situation where a primary gene and the gene that suppresses it do not lie in the same chromosomal locus. Compare: intragenic suppression. (18 Nov 1997) |
| intragenic suppression | <molecular biology> The situation where a primary gene and the mutated gene that suppresses it lie within the same locus. (18 Nov 1997) |
| capon-comb-growth test | A test for androgenic activity, based upon the stimulation of comb growth in capons (castrated cockerels) or immature roosters. Synonym: capon-comb-growth test, cock's comb test. (05 Mar 2000) |
