| microhemagglutination-Treponema pallidum test | A microtiter version of the Treponema pallidum haemagglutination test. Synonym: MHA-TP test. (05 Mar 2000) |
| microhepatia | Abnormal smallness of the liver. Origin: micro-+ G. Hepar (hepat-), liver (05 Mar 2000) |
| microheterogeneity | Slight differences in structure between essentially identical molecules; e.g., in the saccharide portion of a glycoprotein. (05 Mar 2000) |
| microhm | <physics> The millionth part of an ohm. Origin: Micr- + ohm. Source: Websters Dictionary (01 Mar 1998) |
| microincineration | Combustion, in a furnace, of organic constituents in a tissue section so that the remaining mineral ash can be examined microscopically. Synonym: spodography. (05 Mar 2000) |
| microincision | An incision made with the aid of a microscope. (05 Mar 2000) |
| microinjection | The insertion of a substance into a cell through a microelectrode. Typical applications include the injection of drugs, histochemical markers (such as horseradish peroxidase or lucifer yellow) and RNA or DNA in molecular biological studies. To extrude the substances through the very fine electrode tips, either hydrostatic pressure (pressure injection) or electric currents (ionophoresis) is employed. (18 Nov 1997) |
| microinjector | An instrument for infusion of very small amounts of fluids or drugs into animals or humans. (05 Mar 2000) |
| microinstability | <radiobiology> Instabilities due to particle / kinetic- theoretical effects, typically occuring on small scales, as opposed to those derivable from fluid models valid on larger scales. As with other instabilities, these are driven by various types of available free energy. (See also kinetic theory.) (09 Oct 1997) |
| microinvasion | Invasion of tissue immediately adjacent to a carcinoma in situ, the earliest stage of malignant neoplastic invasion. (05 Mar 2000) |
| microinvasive carcinoma | <tumour> A variety of carcinoma seen most frequently in the uterine cervix, in which carcinoma in situ of squamous epithelium, on the surface or replacing the lining of glands, is accompanied by small collections of abnormal epithelial cells that infiltrate a very short distance into the stroma; this may represent the earliest stage of invasion, in which the neoplastic cells are capable of intrusion but not of sustained growth in connective tissue.

| microkatal | One-millionth of a katal. (05 Mar 2000) |
| microkymatotherapy | Treatment with high frequency radiations of 3,000,000,000 Hz (3000 MHz), at a wavelength of 10 cm. Synonym: microwave therapy. Origin: micro-+ G. Kyma, a wave, + therapeia, treatment (05 Mar 2000) |
| microlecithal egg | An egg containing a small amount of deutoplasm. (05 Mar 2000) |
