Supine plasma concentrations of epinephrine and norepinephrine were measured by a radioenzymatic method in 69 patients with essential hypertension and were compared with the levels found in 40 patients with hypertension resulting from chronic parenchymatous renal disease and in 18 normotensive controls. Mean plasma levels of epinephrine and norepinephrine were not statistically different in pri...

In this research the effect of application of different levels of folic acid and time on some quality and agronomic characteristics of strawberry (cultivar Paros) was investigated. The plants were treated by folic acid with concentrations of 0, 20 and 40 mM at two stages (30 days after planting and first blooming) as a factorial experiment using a randomized complete block design with four repl...
