FEATURES OF SKIN WOUNDS HEALING UNDER CHRONIC HYPERGLYCEMIA AND IMPROVEMENT OF THEIR TREATMENT METHODS.

Objective: The aim: The work was aimed to study the histological, morphometric and planimetric features of skin regeneration in mature rats with chronic hyperglycemia under the influence of platelet-rich plasma.

Patients And Methods: Materials and methods: 60 mature white laboratory rats were used. The animals were divided into three groups (I - control with mechanical skin injuries; II - rats with chronic hyperglycemia and modeled mechanical skin injuries; III - animals with the chronic hyperglycemia and modeled mechanical skin injuries which were injected with the platelet-rich plasma).

Improvement of Skeletal Muscle Regeneration by Platelet-Rich Plasma in Rats with Experimental Chronic Hyperglycemia.

Herein, the structural effect of autologous platelet-rich plasma (PRP) on posttraumatic skeletal muscle regeneration in rats with chronic hyperglycemia (CH) was tested. 130 white laboratory male rats divided into four groups (I-control; II-rats with CH; III-rats with CH and PRP treatment; and IV-rats for CH confirmation) were used for the experiment. CH was simulated by streptozotocin and nicotinic acid administration.

The histological and electron microscopic study of the parotid salivary gland in dehydrated rats of different ages.

Objective: Introduction: Water-salt metabolism disorders is one of the main factor of salivary gland pathology development. The aim: To study the morphological structure of the parotid salivary gland of young, mature and old rats at micro- and ultrastructural levels under water deprivation.

Patients And Methods: Materials and methods: The experiment was carried out on thirty six laboratory male rats of different ages (young, mature and old).

DEPENDENCE OF MORPHOMETRIC PARAMETERS OF THE DENTAL OCCLUSION ON THE TYPE OF THE LOWER JAW GROWTH IN CHILDREN WITH CLASS II1 DENTOFACIAL ANOMALIES WHO LINE IN THE NORTHERN UKRAINE.

The aim of the work was to study the structure of dentofacial anomalies in children and adolescents in Sumy city and Sumy oblast, to identify dentoalveolar morphological peculiarities of the occlusion in 10-13 years old patients with class ІІ1 anomalies according to Angle's classification with different types of lower jaw bone growth. A retrospective analysis of 2236 outpatient dental cards of urban and rural patients with orthodontic pathology was conducted. Patients were divided into three age groups: 6-9 years old (early mixed occlusion) - 592 children; 10-13 years old (late mixed occlusion) - 1180 children; over 13 years old (permanent occlusion) - 464 persons; besides 76 patients with class ІІ1 anomalies according to Angle's classification aged 10-13 years were examined.

THE EFFECTIVENESS OF PHYSICAL FACTORS IN THE TREATMENT OF COMPRESSION-DISLOCATION DYSFUNCTION OF THE TEMPOROMANDIBULAR JOINT.

The aim of the study was clinical and functional assessment of the effectiveness of physical factors in the treatment of patients with compression-dislocation dysfunction of the temporomandibular joint. We observed two groups of patients. All patients were undergone the repositioning of the joint heads of the lower jaw.
