|---|---|
| Chayes' method | A method of replacing lost teeth utilizing a mechanical device for the fixation and stabilization of the dental prosthesis which allows "movement in function" of the abutment teeth. (05 Mar 2000) |
| Graupner's method | An obsolete term for a test of the sufficiency of the heart muscle; if a normal subject takes a measured amount of exercise, the pulse rate rises, and after it has begun to fall the systolic blood pressure begins to rise, reaching its maximum a few minutes after the pulse rate; in the case of a weakened heart, the rise in blood pressure is delayed and the amount of increase diminished; in seriously weakened hearts, a fall in blood pressure occurs.

| rhythm method | <gynaecology> A contraceptive method whereby abstinence is practiced a few days before and after the estimated day of ovulation. (12 Dec 1998) |
| Rideal-Walker method | A figure expressing the disinfecting power of any substance; it is obtained by dividing the figure indicating the degree of dilution of the disinfectant that kills a microorganism in a given time by that indicating the degree of dilution of phenol which kills the organism in the same space of time under similar conditions. Synonym: hygienic laboratory coefficient, phenol coefficient. (05 Mar 2000) |
| chloropercha method | A method of filling the root canals of teeth by dissolving gutta-percha cones in a chloroform-rosin medium within the root canal. Synonym: Callahan's method, Johnson's method. (05 Mar 2000) |
| Gruber's method | A modification of the Politzer method in which the patient does not swallow, but says "hoc" at the instant of compression of the bag. (05 Mar 2000) |
| grunstein and hogness method | The Grunstein and Hogness methodis a hybridisation lab technique in which whole, lysed (ruptured) bacterial colonies which have previously been blotted onto a nitrocellulose (or other) membrane are hybridised to a DNA probe. (09 Oct 1997) |
| method | The mode or manner or orderly sequence of events of a process or procedure. See: fixative, operation, procedure, stain, technique. Origin: G. Methodos; fr. Meta, after, + hodos, way (05 Mar 2000) |
| micro-Astrup method | An interpolation technique for acid-base measurement, based on pH and the use of the Siggaard-Andersen nomogram to determine the base deficit as an expression of metabolic acidosis and the arterial PCO2 as an expression of respiratory acidosis or alkalosis. (05 Mar 2000) |
| micro-Kjeldahl method | A modification of the macro-Kjeldahl method designed for the analysis of nitrogenous compounds in relatively small quantities, e.g., specimens in which the total content of nitrogen is in the range of 1 to a few mg. (05 Mar 2000) |
| Roux's method | Division of the inferior maxilla in the median line, to facilitate the operation of ablation of the tongue. (05 Mar 2000) |
| microsphere method | A method for measuring organ blood flow by indicator dilution, but more importantly, a method for measuring the distribution of cardiac output or the intraorgan distribution of blood flow. To measure distribution of flow, neutrally buoyant, chemically inert microspheres that have an indicator property (e.g., radioactivity) are injected into a cardiac chamber or arterial blood. They are presumed to distribute in proportion to the distribution of arterial blood flow. Injected sphere size is selected to be large enough to embolise the vessels of interest. Injected quantity is selected to be large enough to provide statistically meaningful samples and small enough not to alter the organ blood flow under investigation. Organ samples are taken to quantify the distribution of the microspheres and hence the flow. See: Fick method, Stewart-Hamilton method. (05 Mar 2000) |
| mitotic shake off method | <cell biology, procedure> A method of collecting cells in mitosis, so that the chromosomes can be examined and the karyotype determined. Many cultured cells round up during mitosis and so become less firmly attached to the culture substratum. Cells in mitosis thus can be removed into suspension by gentle shaking of the culture vessel, leaving the nonmitotic cells still attached. The number of cells that are in mitosis is usually increased by using a drug, such as colcemid that blocks mitosis at metaphase. (18 Nov 1997) |
| closed circuit method | A method for measuring oxygen consumption in which the subject rebreathes an initial quantity of oxygen through a carbon dioxide absorber and the decrease in the volume of oxygen being rebreathed is noted. (05 Mar 2000) |
