MORPHOMETRIC FEATURES OF THE ELEMENTS OF THE HEMOMICROCIRCULATORY BED IN THE CORTEX OF THE ADRENAL GLANDS INFLUENCED BY THE FOOD ADDITIVES COMPLEX

OBJECTIVE

The aim: To establish the dynamics of changes in the average total diameter, the diameter of the lumen of microvessels in the cortex of the rats' adrenal glands influenced by the long-term action food additives complex.

PATIENTS AND METHODS

Materials and methods: To determine the structural changes of the vessels of the hemomicrocirculatory bed of the cortex of the adrenal glands of rats in our study, we used histological, morphometric and statistical methods.

RESULTS

Results: During the study, we found that the effect of a food additive complex on the vessels of the adrenal glands cortex of rats leads to a violation of hemodynamic conditions in the early stages of the experiment.

CONCLUSION

Conclusions: arterioles, venules and capillaries as a capacitive link of the hemomicrocirculatory bed are actively involved in response to exogenous administration of a complex of food additives (sodium glutamate, sodium nitrite, and ponso 4 R). Processes of change of morphometric indicators of vessels are observed mainly from the fourth week of the experiment.

PARTICULARITIES ASSOCIATED WITH THE EXPRESSION OF GLIAL ACIDIC FIBRILLARY PROTEIN ON THE STRUCTURAL COMPONENTS OF CEREBELLUM OF THE RATS INFLUENCED BY THE FOOD ADDITIVES COMPLEX

OBJECTIVE

The aim: To define the degree for glial acidic fibrillary protein expression on the structural components of cerebellum of the rats in health and when rats influenced by the food additives complex.

PATIENTS AND METHODS

Materials and methods: In order to determine the degree of expression of the immunohistochemical marker GFAP on the structural components of the cerebellum of rats we applied immunohistochemical, morphometric and statistical methods in our study.

RESULTS

Results: In histological specimens at the end of 1st week of observation in the gray matter of the cerebellum there occurred a gradual increase in 1.16 times of the average number of GFAP-positive cells. At the end of 4th week of the experimental study, the average number of GFAP-positive cells increased accurately (at p<0.05 compared to the control group) in 1.27 times, at the end of 8th week it has increased in 1.99 times, at the end of 12th week in 2.25, and at the end of 16th week in 2.39 times.

CONCLUSION

Conclusions: The outcomes of our study are as follows the increase in the average number of GFAP-positive cells is directly related to the decrease in the average number of major neurons of the gray matter of the brain, while the fluctuations in the average number of astrocytic glia cells represent a compensatory mechanism in the recovery of gray matter neurons of the brain from neural stem cells with the subsequent development of reactive astrogliosis and, thereafter the possible development of neuropathology.

[Changes in clinical indices in patients in predisposition for pathological cicatrices formation]

Prophylaxis of ocurrence of pathological cutaneous cicatrices is one of actual problems of plastic surgery of head and neck. Cicatricial changes of tissues, as a consequence of operative interventions and various damaging causes (mechanical, thermal and chemical impact, ionizing irradiation, deep destructive inflammation), were depicted. Propensity for formation of pathological cicatrices we consider as the organism state, in which cicatricial changes occur as an answer for minimal trauma or spontaneously. Detailed analysis of fundamental issues and periodical scientific publications witness the insufficient substantiation of this issue.
