| Maxam Gilbert method | A method of DNA sequencing, based on the controlled degradation of a DNA fragment in a set of independent, nucleotide specific reactions. The resulting fragments have characteristic sizes depending on the sequence of the template, that can be resolved on a sequencing gel. Although no longer the main protocol, Maxam Gilbert sequencing still has advantages, for example for oligonucleotides or covalently modified DNA. See: dideoxy sequencing. (18 Nov 1997) |
| Rehfuss method | Fractional method of gastric activity: a fine tube with fenestrated metal tip is passed into the stomach after a test meal, and small quantities (6 or 8 ml) of the stomach contents are removed at 15-minute intervals and examined. (05 Mar 2000) |
| Pavlov method | The method of studying conditioned reflex activity by the observation of a motor indicator, such as the salivary or electroencephalographic response. (05 Mar 2000) |
| glucose oxidase method | <chemical pathology> A highly specific method for measurement of glucose in serum or plasma by reaction with glucose oxidase, in which gluconic acid and hydrogen peroxide are formed. (05 Mar 2000) |
| Reverdin's method | pinch graft |
| Charters' method | A method of toothbrushing utilizing a restricted circular motion with the bristles inclined coronally at a 45 degree angle. (05 Mar 2000) |
| 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) |
