the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...

elliyeh ghadrdan student research committee, faculty of pharmacy, tabriz university of medical sciences, tabriz, iran moslem najafi department of pharmacology and toxicology, faculty of pharmacy, tabriz university of medical sciences, tabriz, iran introduction in the recent decades, there have been increasing evidence that a bi-directional communication exists among the immune, endocrine and central nervous systems which plays an important role in maintaining the body's homeostasis (jiang et al., 1998; lawrence and kim, 2000; maier, 2003; quan and banks, 2007; tian et al., 2012). oxytocin is a nonapeptide neurotransmitter, hormone produced in hypothalamic nuclei (szeto et al., 2013). it is mainly involved in uterine contraction during parturition and the milk ejection reflex during lactation (petersson et al., 2001). evidence for anti-inflammatory activity of physiol pharmacol 20 (2016) 48-56 www.phypha.ir/ppj abstract introduction: the aim of the present study was to evaluate the effect of oxytocin on the angiogenesis and inflammatory parameters in air pouch model of inflammation. methods: inflammation was induced by injection of carrageenan into pouches in male wistar rats. oxytocin (4.25, 8.5 and 17 μg) was administered intra pouch at the same time as the carrageenan and then for 2 consecutive days. after 72 h, the pouches fluid was collected to determine exudates volume, interleukin 1-beta (il-1ß) and vascular endothelial growth factor (vegf) concentrations. then, the pouches were dissected out, weighed and the hemoglobin concentration was assessed. results: all three doses of oxytocin (4.25, 8.5 and 17 μg) significantly decreased volume of exudates (p<0.05, p<0.01 and p<0.001, respectively) while leukocyte accumulation in the pouch fluid was diminished by 8.5 and 17 μg oxytocin. the granulation tissue weight was also markedly reduced in comparison with the control group. a significant reduction in the angiogenesis rate in oxytocin-treated rats by all doses was seen. interestingly, there was no significant difference between the effect of oxytocin and diclofenac on the inhibition of angiogenesis, vegf concentration and inflammatory parameters except leukocyte accumulation. in addition, administration of oxytocin (17 μg/pouch) significantly decreased il-1ß level (47%) compared to the control group (p<0.05). conclusion: oxytocin has an anti-inflammatory effect and inhibits cell influx and exudation to the site of the inflammatory response. the anti-angiogenesis effect of oxytocin may be related to the local inhibition of vegf levels as similarly shown by diclofenac. physiology and pharmacology sevda mikaily mirak student research committee, faculty of pharmacy, tabriz university of medical sciences, tabriz, iran tahereh eteraf-oskouei department of pharmacology and toxicology, faculty of pharmacy, tabriz university of medical sciences, tabriz, iran

as far as bandura’s (1977) conceptualization of the sense of self-efficacy is concerned, it is argued to be context- and even task-specific, compared to other concepts like self-esteem (brown, 2000); therefore, upon the previous research studies, related theories and definitions, and the ideas and views obtained from the interviews conducted with the scholars, the current research study aimed a...

Inflammatory condition is the consequence of defensive mechanism of immune system against viral and bacterial infection, tissue injury, UV radiation, stress and etc. Persistently acute inflammation leads to chronic phase which is characterized by production of pro-inflammatory mediators from T cells. These molecules (e.g. IL-6, TNF-&alpha, IL-1&beta and IL-17) are mostly pleiotropic cytokines i...

introduction as a tumor grows, the demand for oxygen and nutrients increases and it grows further if acquires the ability to induce angiogenesis. in this study, we aimed to present a two-dimensional continuous mathematical model for avascular tumor growth, coupled with a discrete model of angiogenesis. materials and methods in the avascular growth model, tumor is considered as a single mass, wh...

single-gene disorders occur when mutation in a gene causing alteration of gene function while in multifactorial disorders, mutations occur in multiple genes, and these are usually coupled with environmental causes. in addition, in a multifactorial disorder such as diabetes, the complication is under the influence of different genes. for example, in diabetic retinopathy many genes are involved i...
