electronic cell counter (medicine) and phosphatidylcholine-sterol o-acyltransferase (medicine)

electronic cell counter (medicine)

electronic cell counter
<apparatus, haematology> An automatic blood cell counter in which cells passing through an aperture alter resistance and are counted as voltage pulses, or in which cells passing through a flow cell deflect light.

Some types of counter are capable of multiple simultaneous measurements on each blood sample; e.g., leukocyte count, red cell count, haemoglobin, haematocrit, and red cell indices.

phosphatidylcholine-sterol o-acyltransferase (medicine)

phosphatidylcholine-sterol o-acyltransferase
<enzyme> An enzyme secreted from the liver into the plasma of many mammalian species. It catalyses the esterification of the hydroxyl group of lipoprotein cholesterol by the transfer of a fatty acid from the c-2 position of lecithin. In familial lecithin:cholesterol acyltransferase deficiency disease, the absence of the enzyme results in an excess of unesterified cholesterol in plasma.

Chemical name: Phosphatidylcholine:sterol O-acyltransferase

Registry number: EC 2.3.1.43
