Influence of pallet rich plasma, quercetin and their combination on activity of nitric oxide cycle enzymes in nasal mucosa of patients with atrophic rhinitis.

Objective: Aim: To study the general activity of NO synthases (gNOS), the activity of inducible and constitutive isoforms of NO synthase, the activity of arginases, and the concentration of nitrites in the nasal mucosa under the conditions of local treatment of chronic atrophic rhinitis (AR) with quercetin and platelet-rich plasma (PRP therapy)..

Patients And Methods: Materials and Methods: The study was conducted on 118 patients divided into two groups: control (n=20) and experimental (patients with AR, n=98).

MINERALIZATION OF TEETH ENAMEL AFTER ERUPTION.

Objective: The aim: The paper was aimed at the study of the processes of mineralization of the enamel of the permanent tooth after its eruption.

Patients And Methods: Materials and methods: To study the structure of the enamel of permanent teeth has been carried out using light and electron microscopy. The study of the process of the development of the primordia of the permanent teeth involved 10 culled puppies of 30-40 days of age.

DENTAL CROWN BIOMINERALIZATION DURING ITS HISTOGENESIS.

Objective: The aim: Thepaper wasaimedat thestudyof thebiomineralization processesofa permanentdental crown in thepostnatal period of histogenesis.

Patients And Methods: Materials and methods: The study involved 30 culled puppies aged 30-40 days. To study the histogenesis of the germs of the permanent tooth from the cuticular epithelium in the postnatal period microscopic, electron microscopic, immunohistochemical methods of study have been used.

X-ray analysis of the mandible in patients with crossbite and mandibular displacement.

Objective: Introduction: Significant morphological and aesthetic disabilities of the face, observed during the formation of a cross bite in combination with the displacement of the mandible, prompt the doctors - orthodontists to study carefully the morphogenesis of this anomaly. The aim: Analysis of the mandible structure in patients with a cross bite and lower jaw displac ement based on the analysis of orthopantomograms.

Patients And Methods: Materials and methods: For this study, the orthodontic examination of 20 patients, 18-22 years old, was made they complained about facial asymmetry, displacement of the lower jaw and a violation of the cosmetic centers.
