Abstract
Abstract: This experiment was conducted to study the effect of Laser treatment on LH, FSH, Progesterone and Cortisol and the relationship between them and after physiological functions in adult female rabbits serum affected with hyperthyroidism. Eighteen adult female rabbits at eight months and weighing (1.2 - 1.8 Kg) were used in this experiment. At the end of the two weeks of adaptation, the rabbits were divided equally into three groups. The first group was given distilled water and used as a control. The second and third groups were administered orally with L- thyroxine at a dose of 200µg/Kg body weight daily for twenty days. After the induction of hyperthyroidism, the third group was exposed to laser treatment (40J / cm2) at the thyroid gland region for fifteen successive days for ten minutes on each side of the gland. Where as the second ( hyperthyroid ) group was left without laser treatment. Blood samples were collected from ear vein and LH, FSH, Progesterone and cortisol levels in serum were assayed. On the other hand food, water intake, body temperature and weight of all animals were estimated. The result show significant increase in these hormones in the second group with an increase food, water intake and body temperature as compared with control. The relationship between these hormones and thyroid gland was discussed. Laser treatment to the hyperthyroid gland seems to normalize these hormones.
