Background and Objective: Parkinson’s disease is one of the neurodegenerative diseases along with learning and memory disorder. Phenolic compounds in olive leaf extract have antioxidant properties. The aim of this study was to investigate the protective effect of hydroalcoholic extract of olive leaf on memory disorder induced by dopamine neurons impairment in male rat. Materials and Methods:...
The relaxatory effect of Vitis vinifera leaf extract on rat uterus has been reported and it was postulated that, the extract relaxed through the blockade of voltage dependent calcium channels. The extract also, relaxed rat aorta through NO and was dependent on the functional endothelium. In the present study, the effect of Vitis vinifera hydroalcoholic leaf extract (VHLE) on rat vas deferens pr...
Several reports have shown the various effects of grape (Vitis vinifera) seed extract such as antioxidant, hypotensive, hypolipidemic and vasodilatory effects. The aim of present study was to investigate the effect of grape leaf hydroalcoholic extract on isolated rat tracheal contractions induced by KCl and acetylcholine. The trachea was removed from male adult Sprague-Dawley rat and placed in ...
We studied the effect of administering Cassia auriculata leaf extract to rats with experimentally induced liver damage. Hepatotoxicity was induced by administering 9.875 g/kg bodyweight ethanol for 30 days by intragastric intubation. C. auriculata leaf extract was administered at a dose of 250 mg/kg bodyweight daily in one group and 500 mg/kg bodyweight daily in another group of alcohol-treated...

background: evidences show that aloe vera (a. vera), camellia sinensis, hibiscus sabdariffa and sophora alopecuroides may prevent gastric ulcer induced by non-steroidal anti-inflammatory drugs (nsaids). objective: to examine the protective potential of these plants against indomethacin-induced gastric ulcer in the rat. methods: saline, a. vera leaf gel powder and 70% alcoholic extracts of the o...
امروزه برهم کنش میان سیستم های گلوتاماتی و کانابینوئیدی در برخی از نواحی مغزی مرتبط با حافظه به اثبات رسیده است. بنظر می رسد که هسته آکومبنس با داشتن جایگاهی در مرکز مدارهای نورونی سیستم لیمبیک نقش یکپارچه سازی و تثبیت اطلاعات ورودی از سایر بخش های مغز را برعهده دارد. در این مطالعه، اثرات ناشی از تزریق آگونیست و آنتاگونیست رسپتورهای کانابینوئیدی (cb1) و گلوتاماتی (nmda) به ناحیه پوسته آکومبنس د...
BACKGROUND Oxidative stress has a pivotal role in the pathogenesis and development of diabetic peripheral neuropathy (DPN), the most common and debilitating complications of diabetes mellitus. There is accumulating evidence that Juglans regia L. (GRL) leaf extract, a rich source of phenolic components, has hypoglycemic and antioxidative properties. This study aimed to determine the protective e...
The present study investigates the interaction of aqueous leaf extract of Psidium guajava with muscarinic, serotonergic and adrenergic receptor system using isolated rat ileum, gastric fundus and trachea, respectively. The concentration-dependent contractile response of aqueous leaf extract of Psidium guajava was parallel and rightward of standard agonists, ACh and 5-HT indicating agonistic act...
با توجه به این نکته که سیستم نیکوتینی استیل کولین در فرایندهای یادگیری و عملکردهای حافظه نقش مهمی دارند. لذا در این مطالعه اثرات محیطی و مرکزی نیکوتین و تداخل عمل آن با سیستم آلفا ا-آدرنرژیک در تثبیت حافظه بررسی شد. تزریق درون صفاتی (i. p) نیکوتین (mg/kg 1/5، 1، 0/5) سبب افزایش تثبیت حافظه در حیوانات شد. همچنین تزریق درون بطنی نیکوتین (i. c. v) (mg/rat 1، 0/1، 0/01) نیز سبب افزایش تثبیت حافظه د...
