Lycopene attenuates silver nanoparticle-induced liver injury in albino mice.

Lycopene is a carotenoid widely used for its dominant antioxidant properties and beneficial health effects. Silver nanoparticles (AgNP) have gained attention for use in many medicinal and consumer products, leading to animal, human, and environmental exposure. This study investigated the dose-dependent effects of lycopene on AgNP-induced hepatotoxicity in albino mice.

In vitro and in vivo evaluation of probiotic potential and safety assessment of Bacillus coagulans SKB LAB-19 (MCC 0554) in humans and animal healthcare.

Intravenous human umbilical cord blood improves electrophysiological and metabolic properties in ISO induced myocardial necrosis in rats.

Rats treated with isoproterenol (ISO, 85 mg/kg, sc, twice at an interval of 24 h) showed a significant increase in heart rate, mean arterial blood pressure, pressure rate index, ST elevation on ECG, and a significant increase in the levels of cardiac marker enzymes- lactate dehydrogenase, and creatine kinase in serum and a significant reduction in superoxide dismutase, and catalase and increase in thiobarbituric acid reactive substance activity in heart tissue. Treatment with Human umbilical cord blood (hUCBC; 500 and 1000 microL, iv, via the tail vein; 2 h after the second dose of ISO) significantly restored back to normal levels and showed a lesser degree of cellular infiltration and infarct size in histopathological and planimetry studies respectively. Thus, hUCBC ameliorates cardiotoxic effects of isoproterenol and may be of value in the treatment of myocardial infarction.

Involvement of central noradrenaline, serotonin and dopamine system in the antidepressant activity of fruits of Solanum torvum (Solanaceae).

The methanolic extract (ME) of Solanum torvum seeds and its ethyl acetate fraction (EAF) were investigated for their antidepressant activity using behavioral (forced swim test, FST and tail suspension test, TST) and biochemical (monoamine oxidase, MAO reduced activity) tests. ME (10, 30 and 100 mg kg(-1)) and EAF (10 and 30 mg kg(-1)) dose dependently inhibited the immobility period, increased noradrenaline, serotonin and dopamine levels and inhibited the MAO enzymes in FST and TST using mice. Furthermore, we have observed antagonism between the threshold dose of ME (30 and 100 mg kg(-1)) and EAF (10 and 30 mg kg(-1)) with antagonists on behaviour mediated by neurotransmitters noradrenaline, serotonin and dopamine.

Effect of myricetin on deoxycorticosterone acetate (DOCA)-salt-hypertensive rats.

Caffeine withdrawal retains anticataleptic activity but Withania somnifera withdrawal potentiates haloperidol-induced catalepsy in mice.

The previous study showed that chronic treatment with Withania somnifera extract (WS) inhibited haloperidol-induced catalepsy. It is suggested that caffeine and WS may be useful adjuvants in pharmacotherapy of Parkinson's disease. There are no studies on the effect of haloperidol on mice withdrawn from caffeine or W.

Cardioprotective potential of myricetin in isoproterenol-induced myocardial infarction in Wistar rats.

The study aimed to evaluate the protective role of myricetin obtained from Vitis vinifera (Vitaceae) on heart rate, electrocardiographic (ECG) patterns, vascular reactivity to catecholamines, cardiac marker enzymes, antioxidant enzymes together with morphological and histopathological changes in isoproterenol (ISO) induced myocardial infarction (MI) in male Wistar rats. Rats treated with isoproterenol (85 mg/kg, administered subcutaneously twice at an interval of 24 h) showed a significant increase in heart rate and ST elevation in ECG, and a significant increase in the levels of cardiac marker enzymes - lactate dehydrogenase (LDH), creatine kinase (CK) and aspartate aminotransferase (AST) in serum.
