Urtica dioica L. is an Iranian native pharmacological plant for which little attention has been paid to the anatomical structure. Medical applications of this plant include diabetes therapy, digestive improvement, anemia and kidney disease therapy. Because climatic conditions can affect the anatomical structure which in turn affects pharmacological compositions, research on the anatomy of this ...

The experiment was conducted in factorial test based on a completely randomized design with three replications in greenhouse of Isfahan University of Technology of Iran. Lettuce seedlings were exposed separately to the exhaust emissions in three different exposure times (10, 20 and 30 days) and after the exposure time, their morphological, physiological and anatomical traits were measured and c...

The author studied anatomical variations of the origin of the chorda tympani nerve from the mastoid portion of the facial nerve. The studies were performed on 200 specimens of human temporal bone. It was found that the chorda tympani may arise from the facial nerve in three levels: most commonly from the mid third of its mastoid segment (70%), less commonly from the proximal third (20%), an...

introduction: vertebral arteries arise from the root of the neck as the first branches from the superior-posterior aspect of the subclavian arteries. they ascend the neck to enter the cranial cavity and supply blood to the brain. methods: a total of 20 cadavers (in 10 years) were dissected for the study of variations in the origin of the vertebral artery. this study was conducted in isfahan uni...

it has been well - established that common atrial flutter is due to intraatrial macroreentry and its reentry circuit locates in the right atrium. this reentry circuit has been characterized to involve an area of slow conduction identifiable electrophysiologically at the low posteroseptal right atrium and anatomical narrow isthmus snrrounded by the inferior vena capa, coronary sinus astium and t...

In this research, effect of drought stress on leaf characteristics was investigated in the experimental field of Miandoab Azad University, Iran using four facultative barley cultivars. Two separate experiments were conducted in pot and field conditions. In both experiments a factorial arrangement was used and the treatments were completely randomized in four replications. In each experiment ha...
