[Results of surgical treatment of patients with nonpalpable non-malignant breast tumors].

Results of surgical treatment of 100 patients with nonpalpable non-malignant breast tumors are analyzed. Correlation between x-ray parameters, risk factors, results of ultrasonic and morphological examinations was studied. It was demonstrated that risk factors have no diagnostic value for specification of breast pathological process.

[The susceptibility of different animal species to synanthropic and natural populations of Trichinella].

Pigs have been found to be highly susceptible to the synanthropic (domestic) population of Trichinella [correction of Trachina] and weakly susceptible to the natural (native) one. Fur-bearing animals (polar foxes and foxes) are more susceptible to the natural population of Trichinella [correction of Trachina], but minks are equally sensible to the two variants of T. spiralis.
