Mass spectrographic and isotope studies have shown that potassium, rubidium, and especially cesium are most efficiently taken up by cancer cells.1 It is likely that rubidium and manganese, in addition to zinc, are preferentially taken up by tumors in the brain.9
Rubidium could replace potassium in the Na+K-ATPase (sodium-potassium pump) system.4
The antidepressant activity of rubidium chloride has risen new interest.8 Rubidium acts at the level of the central nervous system (CNS) by increasing synaptic neuro-transmitter levels.5 Rubidium chloride might have application in future psychochemical research and therapy of the affective disorders particularly depressions in an analogous way that lithium may be acting in mania.6
Alkali metals are named because they form special solutions called alkaline solutions when they are mixed with water. “Alkaline” means they have a pH greater than 7. Alkali metals include lithium, sodium, potassium, rubidium and cesium.10
Mass spectrographic and isotope studies have shown that potassium, rubidium, and especially cesium are most efficiently taken up by cancer cells. Tests on mice fed cesium and rubidium showed marked shrinkage in the tumor masses. The ready uptake of cesium and rubidium by the cancer cells lead the writer to the High pH therapy.
Rubidium is believed to stimulate animal metabolism as a result of its chemical similarity to potassium. This resemblance enables researchers to use rubidium-87 in cardiac studies. Rubidium is used in photovoltaic cells, which convert sunlight to electricity.
The period length of the running wheel activity rhythm of cockroaches, which is lengthened by Li+ (lithium), was found to be shortened by administering rubidium chloride in the drinking water. Replacing the Rb+ (rubidium) solution by H2O for four weeks did not bring the period length back to the control value. This is probably due to the long biological half life of Rb+ in the cells. The phenomenon is another instance in which the effect of Rb+ is opposite to that of Li+.
It is well-known that rubidium acts at the level of the central nervous system (CNS) by increasing synaptic neurotransmitter levels, thus allowing the introduction of rubidium-based compounds as antidepressant drugs, with an efficacy as high as that of tricyclic agents, and with fewer side effects. Furthermore, many data prove that a true rubidium deficiency occurs in dialysis patients.
A long term study of chronic rubidium loading in one of these subjects demonstrated no undesirable clinical side effects. Rubidium chloride might have application in future psychochemical research and therapy of the affective disorders - particularly depressions - in an analogous way that lithium may be acting in mania. Rubidium increases normetanephrine formation in rat brain, an effect opposite to that seen in lithium.
In the last few years the antidepressant activity of Rubidium chloride has risen new interest. Fifteen depressed inpatients were studied for three weeks treated with Rubidium chloride. Speedy therapeutic efficacy has been shown, with lack of side effects.
Alkali Metals constitute group 1 of the Periodic Table (other than hydrogen). They are named Alkali Metals because when they are mixed with water they form special solutions called alkaline solutions. Alkaline means they have a pH of greater than 7 - they make basic solutions - not acids. Alkali Metals include Lithium, Sodium, Potassium, Rubidium, Cesium, and Francium. Alkali Metals have one electron in the outer shell that is easily given off. Alkali Metals become +1 charged cations (any positively charged ion is called a cation) when they give away an electron. Alkali Metals form ionic bonds with nonmetals. (They give up the outer electron.)
Rubidium may function like an antidepressant because of its ability to increase serotonin in rats. In studies with mice, rubidium has also helped decrease tumor growth, possibly by replacing potassium in cell transport mechanisms or by rubidium ions attaching to the cancer cell membranes.
Overview of rubidium's biological roles. Rubidium competes with potassium ions for entry in to the body. Rubidium activates and mobilizes lithium. Rubidium chlorided changes circadian rhythms. Rubidium partners with cobalt. Cobalt allows absorption of some 10 minerals. Rubidium enhances the release of norepinephrine. Lithium has the opposite effect. The best source of rubidium is unprocessed Brazil nuts.
Scientists in Belgiam found that rubidium levels in the human brain fall as we age. Rubidium is needed for producing S.O.D. (superoxide dismutase), a major antioxidant.
