|---|---|
| drug therapy, combination | Drug therapy with two or more drugs given separately for a combined effect. (12 Dec 1998) |
| trimethoprim-sulfamethoxazole combination | <chemical> 4-amino-n-(5-methyl-3-isoxazolyl)benzenesulfonamide mixture with 5-((3,4,5-trimethoxyphenyl)methyl)- 2,4-pyrimidinediamine. This drug combination has proved to be an effective therapeutic agent with broad-spectrum antibacterial activity against both gram-positive and gram-negative organisms. It is effective in the treatment of many infections, including pneumocystis carinii pneumonia in aids, but is the drug of choice for urinary infection. Pharmacological action: anti-infective agents, anti-infective agents, urinary, antimalarials. Chemical name: Benzenesulfonamide, 4-amino-N-(5-methyl-3-isoxazolyl)-, mixt. With 5-((3,4,5-trimethoxyphenyl)methyl)-2,4-pyrimidinediamine (12 Dec 1998) |
| ethinyl estradiol-norgestrel combination | <chemical> Ethinyl estradiol and norgestrel given in fixed proportions. It has proved to be an effective contraceptive. Pharmacological action: contraceptives, oral, combined, contraceptives, oral, synthetic, contraceptives, postcoital, synthetic. (12 Dec 1998) |
| antipodal cone | The set of astral rays of a dividing cell extending from the centriole in a direction opposite to the equatorial plate. (05 Mar 2000) |
| arterial cone | The left or anterosuperior, smooth-walled portion of the cavity of the right ventricle of the heart, which begins at the supraventricular crest and terminates in the pulmonary trunk. Synonym: arterial cone, pulmonary cone, pulmonary conus. (05 Mar 2000) |
| blue cone monochromatism | Impaired, but not absent, colour vision with less severely reduced visual acuity than in complete achromatopsia; inherited as an autosomal recessive or as an X-linked disorder (blue cone monochromism; pi cone monochromatism ). (05 Mar 2000) |
| m-cone | Middle wavelength sensitive c. (green c.). (05 Mar 2000) |
| medullary cone | The tapering lower extremity of the spinal cord. Synonym: conus medullaris. (05 Mar 2000) |
| retinal cone | <ophthalmology, physiology> One of the two photoreceptor cell types in the vertebrate retina. In cones the photopigment is in invaginations of the cell membrane of the outer segment. Cones are less sensitive to light than rods, and are differentially sensitive to particular wavelengths of light and therefore important for colour vision. They provide vision with higher spatial and temporal acuity, and it is the combination of signals from cones with different pigments that facilitates colour vision. There are three types of cones, each type sensitive to red, green or blue. Present in large numbers in the fovea. (03 Jul 1999) |
| growth cone | <cell biology> A specialised region at the tip of a growing neurite that is responsible for sensing the local environment and moving toward the neuron's target cell. Growth cones are hand shaped, with several long filopodia that differentially adhere to surfaces in the embryo. Growth cones can be sensitive to several guidance cues, for example: surface adhesiveness, growth factors, neurotransmitters and electric fields (galvanotropism). (18 Nov 1997) |
| growth cone collapse | <cell biology> Loss of motile activity and cessation of advance by growth cones. There are now thought to be specific molecules that inhibit the motility of particular growth cones and are important in establishing correct pathways in developing nervous systems. See: axon pathfinding. (18 Nov 1997) |
| gutta-percha cone | <dentistry> A cone-shaped, semi rigid root canal filling material composed of gutta-percha and zinc oxide. (05 Mar 2000) |
| pi cone monochromatism | Impaired, but not absent, colour vision with less severely reduced visual acuity than in complete achromatopsia; inherited as an autosomal recessive or as an X-linked disorder (blue cone monochromism; pi cone monochromatism ). (05 Mar 2000) |
| cold cone biopsy | <gynaecology, procedure> A procedure which excises a cone of tissue (mucous membrane) off the cervix for purpose of diagnostics and therapeutics (removes precancerous cells). See: cervical dysplasia. (27 Sep 1997) |
