Altered Levels of Nodal Excitability by Rate-Dependent Inhibitory Effects of Essential Oil of Citrus aurantium on the Electrophysiological Properties of Isolated Perfused Rabbit AV-Node: Protective Role in the Prevention of Ouabain Toxicity International Journal of Morphology
Khori,Vahid; Nayebpour,Mohsen; Mansourian,Azad Reza; Davarian,Ali; Naseri,Mohsen; Salehi,Aref; Alizadeh,Ali-Mohamad.
Treatment of supraventricular arrhythmia includes a wide range of medical interventions. Herbal remedies are suitable alternatives to synthetic drugs due to their availability, minimal side effects and lower price. Pharmacological studies and traditional medical literature point to the cardiovascular effects of Citrus aurantium L. (Rutaceae) in many instances. In the present study we used isolated perfused AV-node of rabbit as an experimental model to determine the effect of various concentrations of essential oil of C. aurantium (0.1-0.3 v/v) on the nodal conduction time and refractoriness of an isolated rabbit AV-nodal preparations. Selective stimulation protocols were used to independently quantify AV nodal recovery, facilitation and fatigue in 18...

The increase in the consumption of natural drugs have made their use a Public Health problem due to the possibility of access to products without adequate conditions of use. The concern with the quality of the natural products is due to the potential fungal contamination and the risk of the presence of mycotoxins. Ninety-one samples of medicinal plants were evaluated for the fungal contamination and the mycotoxigenic potential of Aspergillus and Penicillium isolated from the samples. Results indicated that predominant mycoflora was distributed in 10 genera. From these, 89.9% of the isolates corresponded to genera Aspergillus and Penicillium, which are extremely important from the mycotoxicological standpoint. 21.97% of the Aspergillus and Penicillium...
