[The diagnostic value of echography in hepatic echinococcosis].

The ultrasound method of examination led to revolutionary changes in the diagnosis of liver echinococcosis [correction of Echinococcus]. The ultrasound image of this disease, which is common in the region, is presented. The ultrasound method is compared with other diagnostic methods and its importance is pointed out. The ultrasound method of examination is a reliable means for the diagnosis of liver echinococcosis [correction of Echinococcus].

[Hospital and prehospital mortality from acute myocardial infarct during 1982-1984].

The hospital and pre-hospital lethality is discussed for the period 1982-1984 according to the materials of the Clinic of cardiology and the necropsy protocols of the chairs of forensic medicine and pathological anatomy. The role of the risk factors, age and sex for hospital lethality during all three years is given consideration. Hospital lethality was reduced during the last (1984), the relative share of the deceased of cardiogenic shock was decreased. Almost identically high level of pre-hospital lethality persisted during all three years, bringing up the problem of the effectiveness of the primary prophylaxis of ischemic heart disease and improved work at the level of regional and workshop physicians and emergency medical aid.

[Possibilities for information processing and operations simplification in multidimensional tasks of morphokinetic synthesis].

The authors propose an iterative method for separating classes of objects by reduction of multidimentional space of sings, which describe objects by twodimentional space of two integral processings of the differences between sings. For this purpose the differences are evaluated by three steps rating: positive difference, negative difference and no difference. The proposed iterative algorhythm allows by finite and a small number of procedures to remove indeterminace which in the general case is contained in the so defined on the work integral processings. The application of the algorhythm does not require a special mathematical training. Represantation of the objects by integral characteristics is made in twodimentional space. In the paper the report the authors give a generalization for the case of M-steps rating for evaluation of the differences between the signs of the objects.
