The inability of pre-emergence herbicides alone to give season-long weed control in maize production justifies the need for supplementary control. Field trials were conducted evaluate intercropped groundnut and jack bean enhanced efficacy two 2013/2014 2015 cropping seasons at Federal University Agriculture, Abeokuta, Nigeria. experiment was arranged split-plot fitted a randomized complete bloc...

OBJECTIVES We investigated whether the Na+-H+ exchange inhibitor, HOE642 (Hoe), and/or the Na channel blocker, mexiletine (Mex), enhance a cardioprotective effect on St. Thomas' Hospital cardioplegic solution (STS) to clarify the mechanism by which intracellular Na+ is accumulated after cardioplegic arrest. MATERIALS AND METHODS Isolated working rat hearts were perfused with Krebs-Henseleit b...

Acute hypertension inhibits proximal tubule (PT) fluid reabsorption. The resultant increase in end proximal flow rate provides the error signal to mediate tubuloglomerular feedback autoregulation of renal blood flow and glomerular filtration rate and suppresses renal renin secretion. To test whether the suppression of the renin-angiotensin system during acute hypertension affects the magnitude ...

BACKGROUND The accumulation of intracellular sodium during myocardial ischemia couples an inappropriate calcium influx and depressed cardiac recovery during subsequent reperfusion. The effects of the selective sodium/ hydrogen exchange inhibitor HOE 694 are evaluated during myocardial ischemia and reperfusion. METHODS Ten isolated rat hearts were subjected to a 2-minute infusion of St. Thomas...

Background: Nowadays, there's a growing demand for the natural antioxidants due to the harmful effects of synthetic antioxidants. Therefore, introduction of new natural antioxidants (especially those with plant origin) is very important. Objective: The present study explores the chemical constitution and antioxidant activity of leaf extract of Hyssopus officinalis L. and extract of aerial part...

We studied the role of brain kinins in the regulation of cardiovascular function. Intracerebroventricular injection of 380 pmol bradykinin increased mean blood pressure by 20 +/- 2 mm Hg (P < .01) in normotensive Wistar-Kyoto (WKY) rats. Complete inhibition of this effect was achieved with intracerebroventricular administration of the newly synthesized, long-acting B2 receptor antagonist D-Arg,...
