| Somogyi method | A measure of the level of activity of amylase in blood serum, as analyzed by means of the Somogyi method (the most frequently used procedure); one unit is equivalent to 1 mg of reducing sugar liberated as glucose per 100 ml of serum, when an aliquot of the latter is mixed with a standard starch substrate (plus sodium chloride for maximal activation) and incubated for a standard time; normal range is 80 to 150 unit's, but values are usually not regarded as clinically significant unless they are greater than 200.

| split cast method | A procedure for placing indexed casts on an articulator to facilitate their removal and replacement on the instrument, the procedure of checking the ability of an articulator to receive or be adjusted to a maxillomandibular relation record. Synonym: Needles' split cast method. (05 Mar 2000) |
| Stas-Otto method | A method of extraction of alkaloids from plants and animal bodies: the substance is digested in alcohol and tartaric acid, the fatty and resinous matters are precipitated with water, the fluid is made alkaline, and the alkaloids are extracted with ether or chloroform. (05 Mar 2000) |
| Needles' split cast method | A procedure for placing indexed casts on an articulator to facilitate their removal and replacement on the instrument, the procedure of checking the ability of an articulator to receive or be adjusted to a maxillomandibular relation record. Synonym: Needles' split cast method. (05 Mar 2000) |
| Stewart-Hamilton method | Formula to calculate cardiac output after intravenous indicator dye injection; blood flow in liters per minute is given by dividing the amount of injectant in milligrams by the product of the average dye concentration in the initial curve of the dye concentration sampled at a given point in the circulation and multiplied by the dose of dye (in milligrams) to write the curve from appearance to disappearance (in the absence of any recirculation). Synonym: Hamilton-Stewart formula, Stewart-Hamilton method. (05 Mar 2000) |
| Stroganoff's method | An obsolete term for treatment of eclampsia by morphine, chloral hydrate, shielding the patient from all external sources of irritation, and rapid delivery. (05 Mar 2000) |
| Nikiforoff's method | The fixing of blood films by immersion for 5 to 15 minutes in absolute alcohol, a mixture of equal parts of alcohol and ether, or pure ether. (05 Mar 2000) |
| definitive method | An analytical procedure for the measurement of a specified analyte in a specified material which is known to give essentially the true value for the concentration of the analyte. (05 Mar 2000) |
| depletion method | <molecular biology, technique> A lab technique to isolate mRNA molecules from a specific gene by hybridising all of the mRNA molecules from a cell to a specific segment of DNA. The one mRNA molecule type which actually sticks is the one looked for. (09 Oct 1997) |
| Dick method | An intracutaneous test of susceptibility to the erythrogenic toxin of Streptococcus pyogenes responsible for the rash and other manifestations of scarlet fever. Synonym: Dick method. (05 Mar 2000) |
| Dieffenbach's method | <procedure, surgery> A plastic operation for covering a defect by sliding a flap with broad pedicle. (21 Jun 2000) |
| diffusion method | A method for the study of bacterial enzymes in which agar is mixed with the material (e.g., starch or milk) which is to serve as an indicator of the enzyme action and is inoculated and plated; if the bacteria produce enzymes digesting the admixed material, there will be a zone of clearing in the medium about each colony. Synonym: diffusion method. (05 Mar 2000) |
| direct method for making inlays | In dentistry, an inlay technique in which the wax pattern is made directly in the prepared cavity in the tooth. Synonym: direct technique. (05 Mar 2000) |
| disk sensitivity method | A procedure for testing the relative effectiveness of various antibiotics; small disks of paper (or other suitable material) are impregnated with known, appropriate amounts of antibiotic, and then placed on the surface of semisolid medium that has been previously inoculated with the organism being tested; after suitable periods of incubation at 37캜, the lack of growth in zones about the various disks indicates the relative effectiveness of the antibiotic. (05 Mar 2000) |
| double antibody method | A method of separating antibody-bound antigen (e.g., insulin) from free antigen by precipitating the former with antibody specific for immunoglobulin. Synonym: double antibody immunoassay, double antibody method. (05 Mar 2000) |
