Catecholamine release is known to modulate cardiac output by increasing heart rate. Although much is known about catecholamine function and regulation in adults, little is known about the presence and role of catecholamines during heart development. The present study aimed therefore to evaluate the effects of different catecholamines on early heart development in an in vitro setting using embry...

Reserpine is an irreversible inhibitor of vesicular monoamine transporter-2 (VMAT2) used to study Parkinson's disease (PD) and screening for antiparkinsonian treatments in rodents. Recently, the repeated treatment with a low-dose of reserpine was proposed as a progressive model of PD. Rats under this treatment show progressive catalepsy behavior, oral movements and spontaneous motor activity de...

Interactions between striatal dopamine (DA) and neurotensin (NT) have been suggested by anatomical, behavioral, and biochemical studies. Nigrostriatal DA neurons, in contrast to mesocorticolimbic DA neurons, do not appear to contain NT. Thus, distinct neuronal elements subserve interactions between DA and NT within the striatum. We have previously demonstrated that reserpine-induced depletion o...

It has been reported that reserpine causes a prolonged hypertension after the pretreatment of ephedrine and metamphetamine46'47. This hypertension was observed in the previous experiments and the mechanism of the drugs producing the hypertension was discussed. Pheniprazine was proposed as a monoamine oxidase inhibitor by Horita , and reserpine produced a prolonged hypertension after the adminis...

Reserpine functions as an anti-stress agent providing relaxation to animals under stressful conditions. An attempt was made to find out functions of reserpine in unstressed albino rats and its role in steroidogenesis. The effects of the drug (25 and 35 microg, im daily for 3-5 days) were observed by recording the changes in body weights, concentration of ascorbate (liver and adrenals) and chole...

Mismatch repair proteins modulate the cytotoxicity of several chemotherapeutic agents. We have recently proposed a "death conformation" of the MutS homologous proteins that is distinguishable from their "repair conformation." This conformation can be induced by a small molecule, reserpine, leading to DNA-independent cell death. We investigated the parameters for a small reserpine-like molecule ...

Abstract Rauwolfia tetraphylla L., is an important medicinal plant in Apocynaceae family and recognized as alternative source to serpentina terms of anti-hypertensive alkaloid production i.e. reserpine. In view this, the present study conducted estimate reserpine content different parts (leaf, stem root) field grown plants (2 years old), tissue cultured plantlets (R 1 ) (two months old) cell su...

We developed a simplified assay for estimating efflux by measuring the effect of reserpine on the growth of Streptococcus pneumoniae and Staphylococcus aureus over 7 h. Reserpine enhanced ciprofloxacin and levofloxacin 17 to 68%. The hydrophobic drug trovafloxacin and the drug moxifloxacin, with a bulky C-7 substituent but hydrophilicity similar to that of levofloxacin, showed little (0 to 11%)...
