The invention relates to of medicine and medicine equipment and concerns techniques and means for medicinal action with electromagnetic fields to living tissues. A method provides a stimulating effect of an electromagnetic field to metabolic processes in tissues of an organism, that result in positive shifts of a functional state of regulatory systems. On a contactless electromagnetic action to members of a vascular system, biomechanical, bioelectrical and bioresonant processes in the vascular system control the tone of a vascular wall with a high degree of selectivity. The method and device allow to reduce treatment periods, post-operative and other types of rehabilitation due to a deep contactless interaction of biological tissues of a patient, provided by sensor fields of the organism at an information level, with low-frequency electromagnetic fields that are created by the inventive device with special bioadequate parameters relative to dynamic (that is, time and shape parameters), amplitude and geometric-spatial properties. The inventive device consists of a specialized biosynchronized generator of low-frequency electrical signals that arrive at an electromagnetic inductor converting the electrical signals into electromagnetic fields having given electromagnetic properties determined as a result of fundamental theoretical studies and experiments.

The methods described herein enable the evaluation of compounds on subjects to assess their therapeutic efficacy or toxic effects. The target of analysis is the underlying biochemical process or processes (i.e., metabolic process) thought to be involved in disease pathogenesis. Molecular flux rates within the one or more biochemical processes serve as biomarkers and are quantitated and compared with the molecular flux rates (i.e., biomarker) from control subjects (i.e., subjects not exposed to the compounds). Any change in the biomarker in the subject relative to the biomarker in the control subject provides the necessary information to evaluate therapeutic efficacy of an administered drug or a toxic effect and to develop the compound further if desired. In one aspect of the invention, stable isotope-labeled substrate molecules are administered to a subject and the label is incorporated into targeted molecules in a manner that reveals molecular flux rates through one or more metabolic pathways of interest. By this method, a comparison between subjects and control subjects reveals the effects of the chemical entity or entities on the biomarkers. This, in turn, allows for the identification of potential therapeutic uses or toxicities of the compound. Combinations of compounds can also be systematically evaluated for complementary, synergistic, or antagonistic actions on the metabolic pathways of interest, using the methods of the present invention as a strategy for identifying and confirming novel therapeutic or toxic combinations of compounds.

A method for increasing the target-specific toxicity of a drug is effected by pretargeting an enzyme to a mammalian target site, and then administering a cytotoxic drug known to act at the target site or a prodrug form thereof which is converted to the drug in situ, which drug is also detoxified to form an intermediate of lower toxicity using said mammal's ordinary metabolic processes, whereby the detoxified intermediate is reconverted to its more toxic form by the pretargeted enzyme and thus has enhanced cytotoxicity at the target site. Further enhancement can be achieved by pretargeting an enzyme which converts the prodrug to the cytotoxic drug at the target site. Kits for use with the method also are provided. The method and kits permit lower doses of cytotoxic agents, maximize target site activity and minimize systemic side effects.

The metabolic processes involved in the formation of any glucose-based metabolite of a metabolic network are determined. A precursor molecule is labeled with a stable carbon (¹³C) isotope at specific positions. The label is allowed to distribute and rearrange in the system. Metabolites are recovered and analyzed against a control system to determine a set of metabolic pathway substrate fluxes caused by changes to the test system relative to the control system such as the addition of compound being tested as a potential drug.

The invention discloses stewed shrimps for health care and nourishment having the effects of nourishing yin, strengthening yang and supplementing calcium. The stewed shrimps are prepared by the following steps of: selecting wildly fostered crayfishes and washing the crayfishes with clean water; cleaning the crayfishes; opening backs and removing bowels with a knife for later use; stirring and frying white sugar to be yellowish and pouring blend oil into a pan; putting ginger and seasonings for the health care and nourishment into the pan and stirring the materials slightly over small fire; adding flavorings into the pan; adjusting the fire to be big fire and putting the crayfishes into the pan; introducing the fire to burn the crayfishes to bright red with distilled spirit; adding broth to stew the crayfishes; adding gourmet powder or chicken essence; putting a little shallot and caraway into the pan; and taking the food out of the pan and placing the food in a bowl or a plate. The stewed shrimps for the health care and nourishment having the effects of nourishing yin, strengthening yang and supplementing the calcium overcomes the defect that the conventional crayfishes are usually stirred, cooked, steamed and fried directly so that the nutrition and the nourishment value of cooked crayfishes cannot be enhanced, can clear away harmful and toxic substances generated in the metabolic process of a human body and improve disease resistance of the organism, and has the effects of strengthening yang and blood, nourishing yin and conditioning the temperature, activating blood circulation to dissipate blood stasis, and removing pathogenic factors without any toxic or side effect.

This invention describes a novel, two-step method for administering PFC. The first step is designed to block the RES by administration of empty, small, liposomal vesicles (ESV) that are rapidly and preferentially engulfed by macrophages, thereby inhibiting their phagocytosis of subsequently infused PFC emulsions. The second step is the subsequent injection of PFC. ESV are devoid of materials that interfere with the macrophage's metabolic processes and do not impair their ability to clear the circulation of pathogenic organisms. Inhibition of the removal of PFC from the blood stream by the RES will achieve increased circulating PFC, enhanced binding and transport of oxygen throughout the blood stream and consequential reduction of undesirable consequences such as organomegaly and cytokine toxicity.
