A rare clinical case of successful treatment of an interrupted ovarian pregnancy (ОР), the incidence of which is 0.4– 1.3 % of all ectopic pregnancies (ЕР), is described. The exact etiopathogenetic mechanism of OP development is still unknown. The rupture of OP mainly occurs in the first trimester of pregnancy 91.0 %, in the second trimester it is 5.3 %, and in the third it’s 3.7 %. Untimely diagnosis of EP in the ovaries can be fatal with massive bleeding and is associated with the risk of ovariectomy with a subsequent decrease in fertility in patients of reproductive age. It is very difficult to diagnose OP. Differential diagnosis should be carried out with interrupted tubal pregnancy, rupture of the ovarian cyst, as well as with torsion of the ovarian cyst. The article presents the results of a pathomorphological study confirming the diagnosis and adequacy of the performed therapeutic measures. The algorithm of OP diagnosis, justification and decision- making on the method of patient’s management and treatment are shown. The presented clinical case will allow physicians of various specialties to know about this EP rare form, to suspect and successfully diagnose OP in the early stages of gestation, which will avoid severe, and sometimes life-threatening, complications or reduce their development.

The creation of highly efficient equipment is an important component of Kedr-89 Co.'s activity. Organizing and mastering production of such equipment is a long and costly process. It is based on theoretical and experimental studies which cannot be conducted without test benches and highly qualified specialists.Test benches are also used to refine methods of designing existing heat-and mass-exchange equipment to increase the reliability of its design and expand the area of application.At UkrNIIkhimmash Co., a laboratory was established for studying heat-and mass-exchange and separation equipment; it includes the benches: "cold" with a column built up in courses 235 mm in diameter, "cold" with a column 600 mm in diameter or a 1500´400 mm rectangular box, "hot" with a fractional distillation column 100/80 mm in diameter, and also for investigating mixing and separation of mutually insoluble liquids. Figure 1 shows a diagram of "cold" benches for studying the hydrodynamic and mass-exchange characteristics of tray and packed contact devices of different types in the water-air system and in conditions of desorption of ammonia from aqueous solutions with air. In studying hydrodynamics, the benches operate according to a circulation scheme for air and water feed and in studying mass transfer, according to an open scheme for air with periodic renewal of the initial aqueous solution of ammonia to restore the required concentration.The bench with the column 235 mm in diameter (Fig. 2) is primarily intended for studying packing. It is equipped with an air blower and a water pump that allow conducting experiments at a gas velocity in the column of up to 4.6 m/sec and a packing reflux density of up to 100 m 3 /(m 2 ⋅h).The second "cold" bench is equipped with a more powerful air blower which allows testing larger high-output tray contact devices (in testing centrifugal trays, the gas velocity in the tray element is greater than 10 m/sec). To reduce the noise level, the air blower is installed outside of the building in a specially equipped site. To save energy, operation is with recirculation of air.Water is fed to the bench by two pumps with total output of up to 60 m 3 /h, which allows creating reflux density of up to 200 m 3 /(m 2 ⋅h) in the column and up to 150 m 3 /h per 1 m of overflow bar.
