Hypothalamic digoxin--central role in conscious perception, neuroimmunoendocrine integration and coordination of cellular function--relation to hemispheric dominance.
    Medical hypotheses, 2003, Volume: 60, Issue:2

    A family with a high prevalence of Parkinson's disease, schizophrenia, neoplasms, syndrome-X, rheumatoid arthritis and epilepsy has been described. The psychological behavioural patterns of the family were as follows--creativity and high IQ, hypersexual behaviour, reduced appetite and eating behaviour, insomnia and reduced sleep patterns, increased tendency for spirituality, increased tendency for addiction, less of bonding and affectionate behaviour and left handedness. Digoxin, an endogenous Na(+)-K(+) ATPase inhibitor secreted by the hypothalamus, was found to be elevated and RBC membrane Na(+)-K(+) ATPase activity was found to be reduced in all the disorders and in the indexed family studied. Hypothalamic digoxin can modulate conscious perception and its dysfunction may lead to schizophrenia. Digoxin can also preferentially upregulate tryptophan transport over tyrosine resulting in increased levels of depolarising tryptophan catabolites - serotonin, quinolinic acid, strychnine and nicotine and decreased levels of hyperpolarising tyrosine catabolites dopamine, noradrenaline and morphine contributing to membrane Na(+)-K(+) ATPase inhibition in all the above disorders and the indexed family. Digoxin induced membrane Na(+)-K(+) ATPase inhibition can result in increased intracellular Ca(2+) and reduced Mg(++) levels leading to glutamate excitotoxicity, oncogene activation and immune activation. Digoxin induced altered Ca(++)/Mg(++) ratios, reduced ubiquinone and increased dolichol can affect glycoconjugate metabolism, membrane formation and structure and mitochondrial function leading to the diverse disorders described above including those in the indexed family. The isoprenoid pathway and neurotransmitter patterns were compared in right-handed/left hemispheric dominant and left-handed/right hemispheric dominant individuals. The biochemical patterns in the indexed family and the diverse disorders studied correlated with those obtained in right hemispheric dominance. The hyperdigoxinemic state indicates right hemispheric dominance. Hypothalamic digoxin can thus function as the master conductor of the neuroimmunoendocrine orchestra and co-ordinate the functions of various cellular organelles.

Hypothalamic digoxin, hemispheric chemical dominance, and the tridosha theory.
    The International journal of neuroscience, 2003, Volume: 113, Issue:5

    Ayurveda, the traditional Indian System of Medicine, deals with the theory of the three tridosha states (both physical and psychological): Vata, Pitta, and Kapha. They are the three major human constitutional types that both depend on psychological and physical characteristics. The Pitta state is described as a critical, discriminative, and rational psychological state of mind, while the Kapha state is described as being dominant for emotional stimuli. The Vata state is an intermediate unstable shifting state. The Pitta types are of average height and built with well developed musculature. The Vata types are thin individuals with low body mass index. The Kapha types are short stocky individuals that tend toward obesity, and who are sedentary. The study assessed the biochemical differences between right hemispheric dominant, bihemispheric dominant, and left hemispheric dominant individuals, and then compared this with the patterns obtained in the Vata, Pitta, and Kapha states. The isoprenoid metabolites (digoxin, dolichol, and ubiquinone), glycoconjugate metabolism, free radical metabolism, and the RBC membrane composition were studied. The hemispheric chemical dominance in various systemic diseases and psychological states was also investigated. The results showed that right hemispheric chemically dominant/Kapha state had elevated digoxin levels, increased free radical production and reduced scavenging, increased tryptophan catabolites and reduced tyrosine catabolites, increased glycoconjugate levels and increased cholesterol: phospholipid ratio of RBC membranes. Left hemispheric chemically dominant/Pitta states had the opposite biochemical patterns. The patterns were normal or intermediate in the bihemispheric chemically dominant/Vata state. This pattern could be correlated with various systemic and neuropsychiatric diseases and personality traits. Right hemispheric chemical dominance/Kapha state represents a hyperdigoxinemic state with membrane sodium-potassium ATPase inhibition. Left hemispheric chemical dominance/Pitta state represents the reverse pattern with hypodigoxinemia and membrane sodium-potassium ATPase stimulation. The Vata state is the intermediate bihemispheric chemical dominant state. Ninety-five percent of the patients/individuals in the tridosha, pathological, and psychological groups were right-handed/left hemispheric dominant, however, their biochemical patterns were different--either left hemispheric chemical dominant or right hemisp

Isoprenoid pathway-related membrane dysfunction in neuropsychiatric disorders.
    The International journal of neuroscience, 2003, Volume: 113, Issue:11

    The membrane composition and the isoprenoid pathway metabolites important in maintaining cell membrane integrity was studied in neurological and psychiatric disorders. The results indicate alteration in cholesterol:phospholipid ratio of the RBC membrane which is increased in glioma, schizophrenia, and bipolar mood disorder (MDP); decreased in multiple sclerosis and Parkinson's disease; and not significantly altered in epilepsy. The concentration of total glycosaminoglycans (GAG), hexose, and fucose decreased in the RBC membrane and increased in the serum. The RBC membrane Na+-K+ ATPase activity was reduced and serum HMG CoA reductase activity was increased. There were increased serum levels of digoxin, cholesterol, and dolichol and decreased levels of ubiquinone. The serum magnesium and tyrosine levels were reduced and tryptophan increased. The results indicate a defect in membrane formation and a decreased membrane Na+-K+ ATPase activity in all the disorders studied. The results are discussed, and a hypothesis regarding the relationship between these disorders and defective membrane architecture and membrane Na+-K+ ATPase inhibition is presented.

Hypothalamic digoxin, hemispheric dominance, and neuroimmune integration.
    The International journal of neuroscience, 2002, Volume: 112, Issue:4

    The isoprenoid pathway produces three key metabolites--digoxin (membrane Na(+)-K+ ATPase inhibitor, regulator of neurotransmitter transport, and immunomodulatory agent), dolichol (regulatory of N-glycosylation of proteins), and ubiquinone (free-radical scavenger). The pathway was assessed in systemic lupus erythematosis with neuropsychiatric manifestations, slow viral diseases (subacute sclerosing panencephalitis [SSPE], and Creutzfeldt-Jakob disease [CJD]) and patients with recurrent respiratory infections. This was also studied for comparison in patients with right hemispheric and left hemispheric dominance. The isoprenoid pathway was upregulated with increased digoxin synthesis in patients with neurolupus, SSPE, and CJD, and in those with right hemispheric dominance. The tryptophan catabolites were increased and the tyrosine catabolites reduced. In these patients the dolichol and glycoconjugate levels were elevated and lysosomal stability was reduced. The ubiquinone levels were low and free-radical levels increased in these patients. The membrane cholesterol:phospholipid ratios were increased and membrane glycoconjugates reduced. On the other hand, in patients with recurrent respiratory infection and left hemispheric dominance, the reverse patterns and hypodigoxinemia with a downregulated isoprenoid pathway were noticed. The isoprenoid pathway is important in the pathogenesis of neurolupus, CJD, SSPE, and recurrent respiratory infections. Hypothalamic digoxin and chemical hemispheric dominance play an important role in the regulation of immunity.

Detection of endogenous lithium in neuropsychiatric disorders--a model for biological transmutation.
    Human psychopharmacology, 2002, Volume: 17, Issue:1

    The human hypothalamus produces an endogenous membrane Na(+)-K(+) ATPase inhibitor, digoxin. A digoxin induced model of cellular/neuronal quantal state and perception has been described by the authors. Biological transmutation has been described in microbial systems in the quantal state. The study focuses on the plasma levels of digoxin, RBC membrane Na(+)-K(+) ATPase activity, plasma levels of magnesium and lithium in neuropsychiatric and systemic disorders. Inhibition of RBC membrane Na(+)-K(+) ATPase activity was observed in most cases along with an increase in the levels of serum digoxin and lithium and a decrease in the level of serum Mg(++). The generation of endogenous lithium would obviously occur due to biological transmutation from magnesium. Digoxin and lithium together can produce added membrane Na(+)-K(+) ATPase inhibition. The role of membrane Na(+)-K(+) ATPase inhibition in the pathogenesis of neuropsychiatric and systemic disorders is discussed. The inhibition of membrane Na(+)-K(+) ATPase can contribute to an increase in intracellular calcium and a decrease in magnesium, which can result in a defective neurotransmitter transport mechanism, mitochondrial dysfunction and apoptosis, defective golgi body function and protein processing dysfunction, immune dysfunction and oncogenesis.

Digoxin toxicity presenting as altered mental status in a patient with severe chronic obstructive lung disease.
    Heart & lung : the journal of critical care, 1992, Volume: 21, Issue:1

    Gastrointestinal and cardiac manifestations are the commonly considered features of digoxin toxicity. This report describes a patient with severe chronic obstructive lung disease whose primary manifestation of digoxin toxicity is acute alteration of mental status. Neurologic dysfunction may be the sole manifestation of digitalis toxicity. The diagnosis of digoxin toxicity should be considered in elderly patients with altered mental status, even when serum levels are within a therapeutic range.
