Normalization of HPA Axis, Cholinergic Neurotransmission, and Inhibiting Brain Oxidative and Inflammatory Dynamics Are Associated with The Adaptogenic-like Effect of Rutin Against Psychosocial Defeat Stress.

Social defeat stress (SDS) due to changes in biochemical functions has been implicated in the pathogenesis of affective and cognitive disorders. Employing pharmacological approach with adaptogens in the management and treatment of psychosocial stress is increasingly receiving scientific attention. In this study, we investigated the neuroprotective effect of rutin, a bioflavonoid with neuroprotective and anti-inflammatory functions on neurobehavioral and neuro-biochemical changes in mice exposed to SDS.

Reversal and Preventive Pleiotropic Mechanisms Involved in the Antipsychotic-Like Effect of Taurine, an Essential β-Amino Acid in Ketamine-Induced Experimental Schizophrenia in Mice.

Schizophrenia is a life disabling, multisystem neuropsychiatric disease mostly derived from complex epigenetic-mediated neurobiological changes causing behavioural deficits. Neurochemical disorganizations, neurotrophic and neuroimmune alterations are some of the challenging neuropathologies proving unabated during psychopharmacology of schizophrenia, further bedeviled by drug-induced metabolic derangements including alteration of amino acids. In first-episode schizophrenia patients, taurine, an essential β-amino acid represses psychotic-symptoms.

Preventive putative mechanisms involved in the psychopathologies of mice passively coping with psychosocial defeat stress by quercetin.

Derangements of neuroimmune, neurotrophic and neurochemical homeostasis have important implications in psychosocial stress-induced psychopathologies. Whether quercetin, a neuroactive compound, protects against psychosocial stress-induced psychiatric disturbances particularly via neurochemical mechanisms remain less well elucidated. Therefore, we further investigated the putative neurochemical as well as other cellular mechanisms of quercetin on social-defeat stress (SDS) model of psychosocial impairments.

Repeated endosulfan exposure induces changes in neurochemicals, decreases ATPase transmembrane ionic-pumps, and increased oxidative/nitrosative stress in the brains of rats: Reversal by quercetin.

Neurochemical and ATPase deregulations play important role in toxicant-induced neurodegeneration. Previous studies have shown that loss of ATPase ionic-pumps alters neurochemical balance via increased ammonia, oxidative and nitrosative stress. Thus, this study investigated the ameliorative potentials of quercetin on neurochemical, ATPase changes, hyperammonemia and oxidative/nitrosative status in the brains of Wistar rats exposed to endosulfan, a known toxic environmental pesticide that is casually used in many developing countries.

Prevention and reversal of chlorpromazine induced testicular dysfunction in rats by synergistic testicle-active flavonoids, taurine and coenzyme-10.

Evidences have shown that alterations in testicular dehydrogenase and ionic-ATPase activities have important implications in spermatogenesis and sperm capacitation, a penultimate biochemical change required for fertilization. Previous studies have revealed that taurine and coenzyme-Q10 (COQ-10), which are synergistic testicle-active bioflavonoids, with proven gonadotropin-enhancing properties reduce testicular damage in rats. Hence, this study investigated the effects of taurine and COQ-10 or their combination alone, and in the preventive and reversal of chlorpromazine-induced inhibition of testicular dehydrogenase enzymes, electrogenic pumps, sperm capacitation and acrosomal-reaction in male Wister rats.
