摘要:
Growth or metastasization of malignant tumors can be inhibited by administering to a patient in need thereof sufficient lactose to block crucial lectins on the affected organ so that the tumor cells cannot anchor to other locations in the body. Lactose can be administered alone, or in combination with conjugates of cytotoxic drugs. Preferably, lactose is conjugated to a cytotoxic substance so that the primary tumor is treated concurrently with prevention of metastasis. Additionally, by conjugating a cytotoxic drug to lactose, the cytotoxic drug is maintained in close proximity to the tumor because of the receptors on the tumor which bind the lactose (and therefore the cytotoxic agent bound thereto) to the tumor cells. By using a conjugate of lactose with a cytotoxic agent, one dose is generally sufficient to destroy the receptor sites on the tumor and prevent metastasis of the tumor while treating the tumor.

Lubricating compositions are provided which comprise from about 60 to about 80% by weight of at least one saturated dicarboxylic acid, and from about 20 to about 40% of a carrier for said dicarboxylic acid. The lubricating compositions are particularly well suited for use in metal-to-metal lubricating, and are particularly useful in automobile engine lubrication.

A planar millimeter wave circuit for splitting a very wide input frequencyand into three or more lesser bands utilizes bandpass filters exclusively. A triplexer is made by connecting the bandpass filters with coupled line equivalents fed by a conductor with a characteristic impedance the same as the input conductor to the filters and of an appropriate length so as to make the diplexer appear open or nearly open circuited over the adjacent frequency range of a third bandpass filter used in the triplexer or, alternatively, over the adjacent frequency range of a second diplexer connected so as to form a quadruplexer.
摘要:
To extract and purify of polyunsaturated fatty acids, particularly EPA and DHA, without cis-trans conversion, from naturally occurring oils, such as marine animal oil and various vegetable oils a mixture of free fatty acids is first extracted from the oil. The resulting mixture of pure fatty acids is then subjected to separation by means of urea complexing to remove saturated fatty acids and most mono-unsaturated fatty acids. Remaining solvent and urea are then removed from the filtrate which is then subjected to low temperature fractional crystallization in the presence of an organic solvent such as acetone. Substantially pure polyunsaturated fatty acids, especially EPA and DHA, can be separately precipitated by reducing the temperature of the filtrate in two steps. Alternatively, the volume of the filtrate is reduced in two steps and cooled to form precipitates, which are removed. The final product is a mixture of substantially pure DHA and EPA.
摘要:
Hyperacidified tumors having high .beta.-glucuronidase activity can be treated with glucuronides with aglycones toxic to the tumor cells with great safety toward the rest of the body by first administering an alkalinizing agent in an amount sufficient to maintain the pH level of non-tumor tissues at approximately 7.4 during the glucuronide treatment. This will cause inactivation of .beta.-glucuronidase activity in the rest of the body. Novel glucuronides are disclosed the aglycones of which exert a higher toxic effect in an acid environment or is water-soluble only in an alkaline environment. Such compounds have particular utility with the above process. By substituting radioisotopes into the aglycone, diagnosis and in situ radiation therapy may be accomplished. Bacterial cells having .beta.-glucuronidase activity may also be diagnosed and treated in accordance with the present invention. A urine test is disclosed to determine the amount of free glucuronic acid in the urine which is an indication of the presence of a tumor in the body having high .beta.-glucuronidase activity.

Treatment of prophylaxis of thrombo-embolic conditions is obtained through the simultaneous administration of eicosapentaenoic acid and/or docosahexaenoic acid together with one or more of linoleic acid, .gamma.-linolenic acid and dihomo-.gamma.-linolenic acid, either in the form of a pharmaceutical dosage or in the form of a food product such as margarine or cooking oil.
摘要:
A millimeter wave suspended substrate multiplexer is disclosed which is comprised of a plurality of hybrid-filter-hybrid channel dropping sections. The components of the multiplexer are enclosed in a metallic housing forming a cavity surrounding the multiplexer components. Each of the hybrid-filter-hybrid sections is comprised of first and second 90.degree. hybrid couplers which are connected by a pair of identical bandpass filters. Spurious waveguide energy propagation modes which would otherwise be generated in the cavity surrounding the 90.degree. suspended hybrid couplers are eliminated by the use of a plurality of mode suppression pins extending between the top and bottom portions of the metallic housing and passing through the branch lines of the couplers.
