| Klapp's method | Treatment of scoliosis by a series of systematic crawling movements whereby the spine is bent laterally and made more flexible. (05 Mar 2000) |

| Krause's method | A full-thickness skin graft. Synonym: Krause-Wolfe graft. (05 Mar 2000) |
| Fick method | In 1870 A. Fisk proposed that cardiac output can be calculated as the quotient of total body oxygen consumption divided by the difference in oxygen content of arterial blood and mixed venous blood. In the direct Fick method all variables are measured. The indirect Fick method employs a variety of means to avoid measuring mixed venous oxygen content. By extension, the Fick method may be used to measure cardiac output or organ blood flow with any indicator substance for which the rate of uptake or consumption, and the arterial and mixed venous concentrations, can be measured, provided the indicator does not enter or leave the system by any route not being measured. Synonym: Fick principle. (05 Mar 2000) |
| u-score method | An older, simpler, but somewhat less efficient method of linkage analysis than that by maximum likelihood estimation. (05 Mar 2000) |
| flash method | Sterilization of milk by raising it rapidly to a temperature of 178캟, holding it there for a short time, and reducing it rapidly to 40캟. (05 Mar 2000) |
| flotation method | Any of several procedures for concentrating helminth eggs for more reliable results when eggs are difficult to find in direct examination; the flotation method's depend on flotation of helminth eggs on the surface of a liquid of sufficiently high specific gravity, approximately 1.180; 1 part faeces mixed in about 10 parts saturated saline will float most protozoan cysts and nonpercolated helminth eggs. See: zinc sulfate flotation centrifugation method. (05 Mar 2000) |
| Lamaze method | A technique of psychoprophylactic preparation for childbirth, designed to minimise the pain of labour. (05 Mar 2000) |
| Langendorff's method | Perfusion of the isolated mammalian heart by carrying fluid under pressure into the sectioned aorta, and thus into the coronary system. (05 Mar 2000) |
| Lee-White method | A method for determining coagulation time of venous blood in tubes of standard bore at body temperature. (05 Mar 2000) |
| Liborius' method | A method for culturing anaerobic bacteria; a stab culture is made in the appropriate agar medium, then more of the same medium is liquefied and poured into the test tube on top of the stab culture, effectually sealing it from the air. (05 Mar 2000) |
| Ling's method | Gymnastic exercises (as in Swedish movements) without the use of apparatus. Synonym: lingism. (05 Mar 2000) |
| Lister's method | Antiseptic surgery, as first advocated by Lister in 1867; the operation was performed under a cloud of diluted carbolic acid spray, the instruments were dipped in a carbolic solution before use, and the wound was dressed with a thick layer of carbolised gauze; from this was developed the present practice of aseptic surgery. Synonym: listerism. (05 Mar 2000) |
| lod method | <genetics> A method of linkage analysis using an examination of the common logarithm of the ratio of the likelihood for a particular value of the recombination fraction to that if the recombination fraction is 0.5 (i.e., no linkage); thus, a lod score of 3 at a recombination fraction of 0.2 means that the data are 1000 times more readily explained by supposing a recombination fraction of 0.2 than by supposing the loci are unlinked and the recombination fraction is 0.5. Origin: Logarithm of the odds (05 Mar 2000) |
| longitudinal method | In developmental psychology, the study of the life span of one individual involving comparisons of different age levels. Compare: cross-sectional method. (05 Mar 2000) |
