Garlic dialysate suppressed premature ventricular contractions (PVC) and ventricular tachycardia (VT) in ouabain-intoxicated dogs as well as the ectopic rhythms induced by isoprenaline (10(-6) M) and(More)

Helminthic infections can cause an IL-4-dependent polyclonal synthesis of IgE, which is the major cause of the elevated serum levels of this immunoglobulin in tropical populations.

The objectives of this work were to investigate the effects of a garlic dialysate on diastolic blood pressure (DBP), heart rate (HR) and electrocardiogram (ECG) of anaesthetized dogs and its effects on frequency and tension of isolated rat atria. Garlic dialysate led to a drop in DBP (from 112.5 +/- 3.67 to 70 +/- 3.16 mmHg) and a decrease in HR (from 198(More)
