| Callahan's 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) |

| capture-recapture method | Originally, a technique developed by biologists to track wild animal populations; now adapted for epidemiological studies of elusive human populations (e.g., prostitutes, teen runaways, IV drug users).By comparing data from several independent overlapping sample frames, it is possible to adjust for missing cases and to generate estimates of the prevalence of a given condition, for example, AIDS infection.

| Pachon's method | Cardiography, carried out with the patient lying on the left side. (05 Mar 2000) |
| macro-Kjeldahl method | A procedure for analyzing the content of nitrogenous compounds in urine, serum, or other specimens, usually to determine relatively large amounts of nitrogen (e.g., 20 to 100 mg); the specimen is treated with a digestion mixture (copper sulfate and sulfuric acid), heated thoroughly, and made alkaline with a solution of sodium hydroxide; ammonia is then distilled from the mixture, trapped in a boric acid-indicator solution, and titrated with standard hydrochloric or sulfuric acid.

| Gartner's method | A method of measuring venous pressure, based upon Gartner's vein phenomenon; with the patient sitting erect, a vein is selected on the back of the hand which is held dependent, well below the level of the right atrium, and then is raised slowly; when the vein is observed to collapse, the distance between its level and that of the atrium is measured with a millimeter rule; this distance gives the venous pressure in millimeters of blood; thus the vein itself is used as a manometer communicating with the right atrium; highly inaccurate, especially in elderly subjects.

| paracelsian method | The use of chemical agents only in the treatment of disease. (05 Mar 2000) |
| parallax method | Localization of a foreign body by observing the direction of its motion on a fluoroscopic screen while moving the X-ray tube or the screen. (05 Mar 2000) |
| Marshall's method | A quantitative procedure for estimating free and conjugated sulfanilamide in body fluids. (05 Mar 2000) |
| Carpue's method | Rhinoplasty utilizing a flap from the forehead. Synonym: Carpue's method, Indian method, Indian operation. (05 Mar 2000) |
| Gerota's method | Injection of the lymphatics with a dye that is soluble in chloroform or ether but not in water; alkannin, red sulfide of mercury, and Prussian blue are said to be suitable for this purpose. (05 Mar 2000) |
| reference method | An analytical procedure sufficiently free of random or systematic error to make it useful for validating proposed new analytical procedures for the same analyte. (05 Mar 2000) |
| 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) |
