| Kety-Schmidt method | A method for measuring organ blood flow first applied to the brain in 1944 by C. F. Schmidt and S. S. Kety. A chemically inert indicator gas is equilibrated with the tissue of the organ of interest and the rate of disappearance from the organ is measured. Blood flow is calculated on the assumption that the tissue and venous blood concentrations of the indicator gas are in diffusion equilibrium at all blood flow rates and that the rate of disappearance of the indicator from the tissue is a function of how much is in the tissue at any time, i.e., it is assumed to be an exponential disappearance.

| zinc sulfate flotation centrifugation method | A flotation method in which the faecal specimen is suspended in tap water, strained through wet gauze, centrifuged, resuspended in tap water, washed and recentrifuged several times, and then suspended in 33% solution of zinc sulfate and centrifuged at top speed for 45 to 60 sec; a bacteriologic loop may be used to pick up the surface layer, which contains protozoan cysts and helminth eggs.
