Abstract

Used surgical removal of the ovaries are commonly in the events of bone erosion in experimental animals , at a young age used Kmenozj to the events of post- menopausal symptoms .
It seems that female sex hormones played a role in the organization and function of the salivary glands and that the presence of receptors for the hormone estrogen in the glands Alaabiah to female mice .
* Find steps :
- 60 were tested Female rabbits in kind of the weight of each of them about 300 gm .
- The animals were divided into two main groups as follows:
A control group containing 12 animals .
B Group study has been surgical removal of the ovaries in turn, has been divided into six sub - groups containing eight of the animals to be sacrificed :
First , second and third week , and then the first , second and third month in a row .
- After it was removed three pairs of major salivary glands and attended in order to examine the samples as follows:
1. mail.
2. Ordinary optical microscope .
- Three - color dye to examine fibers cola Jane acid Schiff reagent to show carbohydrates .
3. Basal phosphatase enzyme dye to show over Altkalps .
4. Dye acid phosphatase enzymes .
During sacrifice rabbits and then took blood samples from each group and a subset of the immune analyzes radiation for each of the hormones estrogen and Albrouje Sturin .
* Search results :
1 - with the naked eye revealed an increase in the weight of animal experiments in the study group compared to the control group .
2. Study histolegal the using Alheimathuksiln found the following results : -
- Leadership gatherings between vesicles and fatty vesicles between and Walguenoat each other .
- Contraction in the protein - secreting vesicles and sometimes eat in the vesicles and also a contraction in the conductive channels of saliva and in the sub - group Zat months .
- Eat the entire lining of the cells secreting vesicle protein.
- Increase the presence of numbers of blood stretched in the connective tissue.
* These results conclude the following :
Surgical removal of the ovaries :
- Leads to the symptoms of post - menopause.
- Increase the weight and fat gain in the salivary gland .
- Ankmach sacs and Salivary channels .
- The lack of the presence of carbohydrates in the vesicles with the lack of the presence of the enzyme amylase in saliva .
- Lack of acid phosphatase enzyme activity in the blood and saliva.
- Lack of a protein in the salivary vesicles .
