Abstract: Methods of treating a subject with a traumatic central nervous system injury, more particularly, a traumatic brain injury, are provided. The methods comprise a therapy comprising a constant or a two-level dosing regime of progesterone. In one method, a subject in need thereof is administered at least one cycle of therapy, wherein the cycle of therapy comprises administering a therapeutically effective two-level intravenous dosing regime of progesterone. The two-level dosing regime comprises a first time period, wherein a higher hourly dose of progesterone is administered to the subject, followed by a second time period, wherein a lower hourly dose of progesterone is administered to the subject.

Abstract: The present invention provides methods for conferring a neuroprotective effect on a population of cells in a subject following a traumatic injury to the central nervous system. Specifically, the methods of the invention provide for the administration of a progestin or progestin metabolite following a traumatic brain injury. The progestin or progestin metabolite is administered at therapeutically effective concentrations that produce a neuroprotective effect (i.e., a decrease in the loss of neuronal activity) and reduces and/or prevents the various physiological events leading to neurodegeneration, such as, cerebral edema and the immune/inflammatory response.

Abstract: The invention provides an ex-vivo test kit for testing the effectiveness of reversers of multidrug resistance in the blood, serum or plasma of a patient containing the reversers, the kit comprising, a plurality of cell membranes from highly drug-resistant cells, the cell membranes containing proteins which pump drugs and the membranes being respectively attached to a plurality of support surfaces, and a dye which provides a light signal, which dye is pumped by the proteins contained in the membranes.
