摘要:
A method for enhancing the radiosensitivity of cells through the administration of an exogenous cardiac glycoside, such as oleandrin. The magnitude of radiosensitization depends on the duration of exposure of the cells to oleandrin prior to irradiation. Treatment of cells with oleandrin increases the sensitivity of the cells to radiation-induced apoptosis. Thus, treatment with oleandrin and radiotherapy effectively lessens the proliferation of tumor cell populations.
摘要:
A method for the extraction of pharmacologically active components from the oleander plant using supercritical carbon dioxide and combining the extraction with other isolation methods. The extraction is carried out using carbon dioxide at supercritical conditions, with or without the addition of a modifier. The isolated product is recovered in higher yield than with traditional hot water extraction.

摘要:
A method for processing oleander leaves which produces finely processed oleander particles that will yield high levels of oleandrin when subjected to extraction techniques. The method utilizes washing, drying, and passing the oleander leaves through a comminuting and dehydrating apparatus that separates the particles according to size.
