We examined offspring of 9-10 and 3.5-4 month-old female rats. Female offspring (14, 21, 28, 35, and 40 days) of old rats had higher body weight than offspring of young animals. No intergroup differences were revealed in the body weight of male offspring. At the age of 40 days the offspring of old females differed from the offspring of young rats by higher absolute weight of the brain (females), lower size of ganglionic neurons in the parietal lobe (males and females), and lower blood testosterone concentration (males). Thirty-day-old offspring of old rats exhibited higher locomotor activity and lower degree of anxiety compared to the offspring of young animals.

The recurrent paratonsillitis caused by medium dental caries is an extremely rare condition. Patients with this pathology are admitted to otorhinolaryngological departments and in most cases they do not actively present odontogenic complaints. Currently, the algorithm for the mandatory examination of patients with paratonsillitis does not include an examination by a dentist. This article presents a clinical case of recurrent paratonsillitis in a 22-year-old man. His admission due to this condition was the third during the year. The disease proceeded without signs of affection of the palatine tonsils. In this regard, the patient was examined according to clinical recommendations using additional research methods to verify the source of infection. To exclude the formation of peritonsillar abscess, the non-invasive diagnostic methods were used - transoral ultrasound of peritonsillar tissues. This examination revealed an abnormal arrangement of the external carotid artery branches. This circumstance determined the choice of treatment tactics, excluding the use of relaxing incisions in the peritonsillar area. A laboratory study of saliva determined the activity of -amylase, pH value was measured to exclude an inflammation of the salivary glands. An additional examination revealed the odontogenic etiology of paratonsillitis.

Objectives to evaluate the realism and usefulness of the model developed by us "The ear simulator for practicing emergency care skills in otorhinolaryngology". Material and methods.49 otorhinolaryngologists participated in the study. They performed the initial surgical debridement of the external ear, removal of earlobe atheroma, otoscopy, removal of foreign bodies of the external auditory canal, and paracentesis of the tympanic membrane using the developed simulator. The results were evaluated using a questionnaire on practicing emergency care skills in otorhinolaryngology. Results.The majority of the specialists (94%) defined the developed ear simulator as an adequate model for training, while 83% considered it possible to use it as a training tool for practicing doctors. Conclusion.The developed model of the simulator is intended for practical training of students and residents in otiatrics in the scope of performing emergency and urgent manipulations.
