|---|---|
| Bence Jones protein | <haematology, oncology> These proteins are dimers of immunoglobulin light chains, normally produced by plasma cells. Bence Jones proteins are sufficiently small to be excreted by the kidney. It is a characteristic protein found in the urine of most patients with multiple myeloma. It can be used to help in diagnosis of the disease and to monitor the response to treatment. Quantification requires a 24 hour urine collection. See: Bence Jones reaction (06 Oct 1997) |
| Bence Jones proteins | Proteins with unusual thermosolubility found in the urine of patients with multiple myeloma, consisting of monoclonal immunoglobulin light chains. See: Bence Jones reaction. See: immunoglobulin. (05 Mar 2000) |
| Bence Jones proteinuria | Presence of Bence Jones proteins in the urine, usually indicative of a neoplastic process such as multiple myeloma, amyloidosis, or Waldenstrom's macroglobulinaemia. (05 Mar 2000) |
| Bence Jones reaction | <investigation> The classic method of identifying Bence Jones protein. This protein precipitates from urine in the range of 45 to 70 degrees Centigrade. It goes into solution at temperatures above or below this range. Used in the diagnosis of multiple myeloma. Less commonly, this test is positive in Waldenstrom's macroglobulinaemia, chronic lymphocytic leukaemia and amyloidosis. (27 Sep 1997) |
| Gomori-Jones periodic acid-methenamine-silver stain | <technique> A staining method using methenamine silver, periodic acid, gold chloride, haematoxylin, and eosin to delineate basement membrane, reticulin, collagen, and nuclei; used in renal histopathology. See: Rambourg's periodic acid-chromic methenamine-silver stain. (05 Mar 2000) |
| Price-Jones | Cecil, English haematologist, 1863-1943. See: Price-Jones curve. (05 Mar 2000) |
| Price-Jones curve | A distribution curve of the measured diameters of red blood cells; it is to the right of the normal curve (i.e., indicating larger diameters) in instances of pernicious anaemia and other forms in which macrocytes are present, and to the left (i.e., indicating smaller diameters) in iron deficiency and other forms of microcytic anaemia.

| davy jones | The spirit of the sea; sea devil; a term used by sailors. "This same Davy Jones, according to the mythology of sailors, is the fiend that presides over all the evil spirits of the deep, and is seen in various shapes warning the devoted wretch of death and woe." (Smollett) Davy Jones's Locker, the ocean, or bottom of the ocean. Gone to Davy Jones's Locker, dead, and buried in the sea; thrown overboard. Source: Websters Dictionary (01 Mar 1998) |

| Jones reducer | <apparatus> An apparatus made up of a column filled with amalgamated zinc which isused to reduce solutions. (09 Oct 1997) |
| Abbe test plate | <equipment> A long, wedge-shaped coverslip about 0.20 mm thick at one end and 0.10 to 0.12 mm at the other end coated chemically with a silver film on which are ruled horizontal lines. at each variation in thickness of 0.01 mm there are vertical lines. By means of oblique illumination and by focusing on different portions of the plate, it is possible to determine the optimum coverslip thickness for any objective and also, for microscopes with drawtubes, the tube length for best objective performance. The approximate freedom from spherical and chromatic aberrations can also be estimated. Small isolated bits of silver near the edges of the lines form good objects for the star test (05 Aug 1998) |
| acetone test | A test for ketonuria; the suspected urine is shaken up with a few drops of sodium nitroprusside, and strong ammonia water is then gently poured over the mixture; if acetone is present, a magenta ring forms at the line of contact; tablets containing sodium nitroprusside and alkali are now more commonly used.
