چکیده
Pancreas is a flat organ resembling the letter L or pear shaped, almost yellowish to pink, is of medical significance as the target in two life-threatening diseases of diabetes mellitus and pancreatic cancer. The study was conducted on male rabbits which are distributed into 3 groups by age (6 months, 1 year, 3 years). Physiological and histological changes of pancreas were studied according to age groups adopted. Physiological aspect was done to analysis level of pancreatic gland hormones, the histological structure of pancreas was also studied during the same periods in which hormonal changes were analyzed. Results showed significant differences in the concentration of pancreatic gland hormones, where insulin was in the second group more than in the first and third groups, while blood sugar (glucose) was the highest concentration in third group compared to the first and second. Changes were also show in the tissue structure of pancreas during age, although the basic structure is similar to all samples. As age increase (1-3) years, Langerhans islets increased in size, contained alpha and beta cells that were surrounded by a loose connective tissue in the third stage, and there was no significant difference in diameters of cells which produce enzymes at all stages of life. Physiological and histological changes indicated to the role of age in function and structure of pancreas gland during different stages of life. In addition, this study indicated that the hormonal variability of pancreas is closely related to the histological composition of gland components, therefore more detailed studies such as sex, different breeds or environmental conditions are worthwhile and may give more information on factors that may affect on effectiveness and activity of gland.
