Nabipour, A., Alishahi, E. and Asadian, M. 2009. Some histological and physiological features of avian kidney. J. Appl. h i m . Res.,.The detailed histology of the kidney was studied i n rock dove, collared dove and owl (3 each). Each kidney consisted of a caudal, a middle and a cranial division. The cortex made up the vast majority of the kidney with only a small portion as medulla. They were arranged in cones of different lengths, which were distributed randomly within the kidney. Medullary nephron tubules were arranged in a sequential manner in all birds. Thick and thin limbs of Henle were separated by the collecting ducts.

Background: The staff performance in health care system is related to their satisfaction. The aim of this research is to investigate the relationship between the work-family conflict and the job satisfaction of medical staff after implementing the health system development plan (HSDP). Methods: Amongst the 350 staff of Damghan Vellayat hospital, 150 of them have been selected in 2016 by random sampling. Two questionnaires, "staff satisfaction" and "work-family conflict", have been used as the data gathering tool after implementing the HSDP. Results: A total of 48.8% of the respondents were female and 52% of them were male and had a mean age of 34.5. The relationship between staff satisfaction and job dimensions has been determined significantly by Pearson correlation coefficient (r = 0.463, P = 0.000). In addition, the relationship between staff satisfaction and conflict with family were significant (r = 0.245, P = 0.000). The difference between men and women in job improvement and job (P = 0.027) stress factors were significant (P = 0.07). Among all the men, 95.4% of them have gotten more than 50 scores (this indicates the job importance in comparison to family life). Therefore, the job importance in comparison to family life is more in the male staff. Conclusions: According to the findings, gender, job category, lack of sufficient educations, and the physical place as well as job dimensions have a direct relationship with job satisfaction and its conflict with family and work relation after implementing the health system development plan.
