1. The present study was conducted to investigate whether brain somatostatin increases feed intake in neonatal chickens. The mediating role of neuropeptide Y receptors on feed intake induced by somatostatin was investigated. 2. In this study, seven experiments were designed, each with four treatment groups (n = 44 in each experiment). In Experiment 1, chicks received control solution and 0.5, 1 and 2 nmol of somatostatin through intracerebroventricular (ICV) injection. In experiments 2, 3 and 4, chickens were ICV injected with control solution and 1.25, 2.5 and 5 μg of B5063 (NPY1 receptor antagonist), SF22 (NPY2 receptor antagonist) and SML0891 (NPY5 receptor antagonist), respectively. In experiment 5, 6 and 7 chickens received ICV injection of B5063, SF22, SML0891, with a co-injection of + somatostatin, control solution and somatostatin. The cumulative feed intake was measured until 120 min post injection. 3. Somatostatin significantly increased feed intake in FD3 chicks. Both B5063 and SML0891 dose-dependently decreased feed intake compared with the control group, while SF22 led to a dose-dependent increase in feed intake. In addition, the hyperphagic effect of somatostatin significantly decreased with co-injection of B560 plus somatostatin (p < 0.05), but SF22 and SML0891 had no effect on feed intake induced by somatostatin in chicks (p > 0.05). 4. Based on the results of this study, it is likely that somatostatin increased feed intake and NPY1 receptor acts as a mediator in hyperphagic effect of somatostatin in neonatal chicks.

This study aimed to identify factors affecting quality of life of rural staff aquaculture units in the selseleh township that has been with Exploratory and confirmatory methods. This research is a survey practical that need data's were collected using questionnaires and interviews of the 160 workers, 35 of rural aquaculture in the region as a whole number. Initially by doing a comparative study documentary in the previous literature and a pilot study of 15 members of community members has been that helped to Reliability and validity of the survey instrument to complete a standard questionnaire and then one scale consisting 34-item and 12 indicators of both economic and social impacts for this study were selected. The analysis was exploratory and confirmatory factor analysis that helps of spss software and required tests were performed in three stages: the first stage for detection sampling adequacy and Bartlett and varimax rotation, 7 The primary factors were extracted. In the second stage verification method identified five independent variables were defined by regression function that ability explanted effective quality of life of rural staff aquaculture in the region. In third analysis stage it became clear that underlying variables of marital status, income and housing conditions can influence the quality of life for community members. Summing up results of three exploratory analysis, verification and underlying that: contribution retrieved from social factors on quality of life of rural staff aquaculture units in the selseleh township is most of the economic dimensions. since the main objective of establishing aquaculture units achieving employment and sustainable security economic- Social in the region and is very important, however it does not require the neglect of the environment dimension of sustainable development.
