| artificial Vichy salt | A mixture of sodium bicarbonate, anhydrous magnesium sulfate, potassium carbonate, and sodium chloride; an antacid. (05 Mar 2000) |
|---|---|
| artificial wetland | <ecology> Wetlands created by the activities of man, either purposefully or accidentally. (09 Oct 1997) |
| cardiac pacing, artificial | Regulation of the rate of contraction of the heart muscles by an artificial pacemaker. (12 Dec 1998) |
| pacemaker, artificial | A device designed to stimulate, by electric impulses, contraction of the heart muscles. It may be temporary (external) or permanent (internal or internal-external). (12 Dec 1998) |
| pancreas, artificial | Devices for simulating the activity of the pancreas. They can be either electromechanical, consisting of a glucose sensor, computer, and insulin pump or bioartificial, consisting of isolated islets of langerhans in an artificial membrane. (12 Dec 1998) |
| membranes, artificial | Artificially produced membranes, such as semipermeable membranes used in artificial kidney dialysis, monomolecular and bimolecular membranes used as models to simulate biological membranes. These membranes are also used in the process of guided tissue regeneration. (12 Dec 1998) |
| chromosomes, yeast artificial | Chromosomes in which fragments of exogenous DNA ranging in length up to several hundred kilobase pairs have been cloned into yeast through ligation to vector sequences. These artificial chromosomes are used extensively in molecular biology for the construction of comprehensive genomic libraries of higher organisms. (12 Dec 1998) |
| pneumoperitoneum, artificial | Deliberate introduction of air into the peritoneal cavity. (12 Dec 1998) |
| pneumothorax, artificial | Injection of air or a more slowly absorbed gas such as nitrogen, into the pleural space to collapse the lung. It was formerly used to treat pulmonary tuberculosis. (12 Dec 1998) |
| heart, artificial | A pumping mechanism that duplicates the output, rate, and blood pressure of the natural heart. It may replace the function of the entire heart or a portion of it, and may be an intracorporeal, extracorporeal, or paracorporeal heart. (12 Dec 1998) |
| saliva, artificial | A solution used for irrigating the mouth in xerostomia and as a substitute for saliva. (12 Dec 1998) |
| skin, artificial | Synthetic material used for the treatment of burns and other conditions involving large-scale loss of skin. It often consists of an outer (epidermal) layer of silicone and an inner (dermal) layer of collagen and chondroitin 6-sulfate. The dermal layer elicits new growth and vascular invasion and the outer layer is later removed and replaced by a graft. (12 Dec 1998) |
| insemination, artificial | Artificial introduction of semen into the vagina for the purpose of inducing conception. (12 Dec 1998) |
| insemination, artificial, heterologous | Human artificial insemination in which the semen used is that of a man other than the woman's husband. (12 Dec 1998) |
| insemination, artificial, homologous | Human artificial insemination in which the husband's semen is used. (12 Dec 1998) |
