[ 1 ] - بررسی نقش و مکانیسم احتمالی عوامل تغذیه‌ای بر نسبت جنسیتی جنین
مقدمه: بروز بیماری‌های خاص ژنتیکی که در جنس خاص تظاهر می‌کند و همچنین تغییرات نسبت جنسیتی در برخی کشورها، علاقه به مقوله تعیین جنسیت را افزایش داده است. روش‌های متفاوتی برای تعیین جنسیت وجود دارد که در این بین رژیم غذایی با توجه به عدم نیاز به تجهیزات خاص، سهولت، در دسترس و ارزان بودن آن، مورد توجه قرار گرفته است. مطالعه حاضر با هدف بررسی اینکه چه عوامل تغذیه ای می توانند بر نسبت جنسیتی تأثیرگذ...
[ 2 ] - Protective effects of long-term administration of Ziziphus jujuba fruit extract on cardiovascular responses in L-NAME hypertensive rats
Objective: Ziziphus jujuba stimulates the release of nitric oxide (NO). Because NO is involved in cardiovascular regulations, in this study the effects of hydroalcoholic extract of Z. jujuba on cardiovascular responses in acute NG-nitro-L-arginine methyl ester (L-NAME) hypertensive rats were evaluated. Materials and Methods: Rats were divided into 6 group (n=6): 1) saline, 2) L-NAME received (...
[ 3 ] - Doxorubicin-induced renal inflammation in rats: Protective role of Plantago major
Objective: The aim of the present study was to evaluate the possible protective effect of Plantago major (P. major) extract against doxorubicin (DXR)-induced renal inflammation in rats. Materials and Methods: 80 male albino rats were randomly divided into 8 groups as follows: control, DXR, Ext (extract) 600, Ext1200, dexamethasone+DXR, vitamin E+DXR, Ext600+DXR, and Ext1200+DXR. Duration of the...
[ 4 ] - مقایسه اثرات آنتی اکسیدانی عصاره های آبی- الکلی زردچوبه و سیاه دانه با ویتامین ث بر شاخص های آسیب اکسیداتیو کلیه موش صحرایی
Background and Aim: The aim of this study was to compare the effects of hydro-alcoholic extract of Curcuma longa (C.L E) and Nigella sativa (N.S E) with Vitamin C on renal-oxidative damage in rats. Methods: 40 male Wistar rats were randomly divided into five groups (n=8) as follows: A Control group with plain drinking water and intervention groups including positive control groups with Vitamin...
[ 5 ] - The protective effects of Curcuma longa extract on oxidative stress markers in the liver induced by Adriamycin in rat
Introduction: The aim of the study was to investigate the effects of Curcuma longa (C. longa) extract on Adriamycin-induced hepatotoxicity in rat. Methods: Animals were divided in six groups: Control (CO), Adriamycin (ADR), Adriamycin with Vitamin C (ADR+VitC), Vitamin C (Vit C), C. longa with Adriamycin (CL+ADR) and without Adriamycin (CL-ADR). Hepatotoxicity was induced by Adriamycin 5mg/kg ...
[ 6 ] - The Effect of Some Herbal Extracts on Nitric Oxide Production in Endothelial Cells 3T3 Cell Line
Introduction: Some studies have demonstrated the potential of herbal drugs for the treatment of various diseases associated with impaired vascular nitric oxide (NO). For diagnosis of the mechanism of these herbal plants, it seems necessary to evaluate the herbal extracts on the Endothelium cell. The aim of the study was to investigate the effect of extract of Trigonella foenum-graecum (T.foenum...
[ 7 ] - Effect of long-term administration of Ferula gummosa root extract on serum oxidant–antioxidant status
Ferula gummosa Boiss is a good source of biologically active compounds such as monoterpene and sesquiterpene derivatives. There are also several reports on antioxidant effects of these compounds. The aim of this study was to investigate the effect of daily administration of F. gummosa root hydro-alcoholic extract on serum oxidant-antioxidant status. Twenty four Wistar rats were randomly divided...
[ 8 ] - Effect of Plantago major extract on doxorubicin-induced nephropathy in rat
Introduction: Nephropathy is defined as rational loss of renal function related with glomerulosclerosis and declining glomerular filtration rate. Inflammation and oxidative stress play a critical role in nephropathy. Plantago major has antioxidant effects. The aim of present study is the investigation of the effect of Plantago major hydro-alcoholic extract on the oxidative stress and renal func...
[ 9 ] - The Effects of Inactivation of Pedunculopontine Tegmental Nucleus by Cobalt (II) Chloride on Cardiovascular Responses in Hemorrhagic Hypotensive Rats
Introduction: Based on the evidence, the Pedunculopontine Tegmental nucleus (PPT) is involved in cardiovascular function regulation. In this study, the probable role of PPT on cardiovascular parameters in the hypotension induced by Hemorrhage (HEM) was evaluated. Methods: The study rats were divided up into 5 groups: 1. Control (Saline); 2. Cobalt(II) chloride (CoCl2); 3. HEM; 4. Saline+HEM; ...
[ 10 ] - Comparative Effects of Metformin and Glibenclamide on Aortic Reactivity to Vasodilator and Vasoconstrictor Agents in STZ-Induced Diabetic Rats
Background: Diabetes is an important risk factor for cardiovascular events. Endothelial dysfunction is the main reason cause of disability and death in diabetic patients and death. The present study investigates the effects of metformin and glibenclamide on vasoconstrictive and vasodilative responses in the diabetic rat aorta. Methods: Rats were divided into four experimental groups (con...
[ 11 ] - Cardiovascular effects of standardized hydroalcoholic extract of Ribes khorasanicum fruit in acute hypertensive rats
Objective: Ribes khorasanicum (R. khorasanicum)traditionally has been used for the treatment of higher blood pressure. In this study, the effect of hydroalcoholic extract of R. khorasanicum fruit in normotensive and hypertensive rats was evaluated. Materials and Methods: Animals were assigned into the following groups: 1) Control, 2) AngII (50 ng/kg), 3) ...
[ 12 ] - Involvement of the 5-HT1A receptor of the cuneiform nucleus in the regulation of cardiovascular responses during normal and hemorrhagic conditions
Objective(s): The 5-hydroxytryptamine1A (5-HT1A) receptor is one of the serotonin receptors in the brain, which regulates cardiovascular responses, especially in hemorrhage. Presence of this receptor in the cuneiform nucleus (CnF) has been shown. The present study evaluates the cardiovascular effect of this receptor of the CnF in normal and hypotensive hemorrhagic rats...
[ 13 ] - Cardiovascular Effect of Cuneiform Nucleus During Hemorrhagic Hypotension
Introduction: The underlying mechanism responsible for the cardiovascular response to hemorrhage (HEM) is still unknown; however, several brain areas, such as the cuneiform nucleus (CnF) have shown to be involved. In this study, the cardiovascular effect of the CnF during HEM was evaluated. Methods: The animals were divided into the following groups: 1. Vehicle; 2. HEM; 3. Cobalt chloride (CoC...
[ 14 ] - Cardiovascular Effect of Dorsal Periaqueductal Gray During Lipopolysaccharide-induced Hypotension
Introduction: The central mechanism related to the cardiovascular response to lipopolysaccharide (LPS)-induced hypotension is not entirely known, but it is suggested that numerous brain areas such as dorsal periaqueductal gray (dPAG) are involved in this process. In the current work, the cardiovascular effect of the dPAG during LPS-induced hypotension is investigated. Methods: The study animal...
