Abstract

Background: Hypertension is one of the most common diseases in recent century with several complications. The purpose of this study was to evaluate the effect of hydroalcoholic extract of Juglans regia L. leaves (Walnut tree) on blood pressure and its interaction with the adrenergic system in male rats. Methods: In this experimental study that established in the physiology lab, School of scinse in Shiraz University from September to October 2013, in order to determine some of hydroalcoholic extract of Juglans regia L. leaves effect on blood pressure, the present study was performed by following procedure: 10 adult male wistar rats weighing between 180-250g were used. They were divided into two groups (Each group contained 5 rats) randomly: Juglans regia L. leaf extract group and Juglans regia L. leaf extract and adrenaline group. Then each rat was anesthetized by IP injection of 1.2 g/kg urethane. After tracheostomy the femoral vine and artery were cannulated for drug injection and blood pressure recording respectively. Arterial cannula for recording arterial blood pressure connected to a pressure transducer (PowerLab, ADInstruments, Sydney, Australia). Blood pressure parameters were recorded before and after IV administration of hydroalcoholic extract of Juglans regia L. leaf, solvent, adrenalin and extract with adrenaline. Results: The result showed a significant decrease of mean arterial pressure, systolic and diastolic pressure in response to extract with compare to control and sham group (P

Arterial cannula for recording arterial blood pressure connected to a pressure transducer (PowerLab, ADInstruments, Sydney, Australia). Blood pressure parameters were recorded before and after IV administration of hydroalcoholic extract of Juglans regia L. leaf, solvent, adrenalin and extract with adrenaline. Results: The result showed a significant decrease of mean arterial pressure, systolic and diastolic pressure in response to extract with compare to control and sham group (P<0.05). Also a significant decrease of blood pressure showed in presence of walnut leaf extract and adrenaline with compare to sham group (P<0.05). Conclusion: It can be concluded that hydroalcoholic extract of Juglans regia L. leaf suggested as a hypotensive agent. It seems that this effect is probably due to inhibitory effect on adrenergic system. [ABSTRACT FROM AUTHOR]

Abstract

This study was carried out to determine the best method and time of budding and grafting in walnut under controlled conditions in Saman, Chaharmahal Va Bakhtiari Province. The experiment was in completely randomized design with 13 treatments, including cleft, splice and whip-tongue grafting on February 4, chip budding on April 4, 19, May 5 and 20, and T-budding and patch budding each one on first of June, July and August in three replications (each replication, including ten seedlings). All grafted seedlings were cultivated in 10-liter plastic pots. Plants were transferred into the greenhouse at about 25 °C and relative humidity of at least 70%. Chip budding, T-budding and patch budding was performed in the greenhouse. Successful budding and grafting were determined after four and 12 weeks, respectively. Furthermore, stem length, diameter and leaf number were evaluated after 12 weeks. The results were suggestive of significant differences between the different grafting methods and times at 1% level. The highest successful grafting was obtained in T-budding (100%) and patch budding (93.3%) in August, followed by T-budding and patch budding in July (80%), and patch (73/3%) and T-budding (60%) in June. Cleft and whip-tongue indicated 46% and 40% successful grafting, respectively. In this study, splice and chip grafting were not proven successful. The highest length and diameter of scion were obtained from the patch budding in June, and the highest leaf number was obtained in whip-though grafting. Finally, the best successful grafting was obtained when grafting was conducted at August, and the highest scion length and diameter were obtained when grafting was carried out in June.
