[Correspondence analysis and combination of molecular genetic and morphological data in zoological systematics].

A new algorithmic approach is proposed for correspondence analysis of different types of data in zoological systematics. The algorithm is tested on actual data. A high degree of correspondence is shown for morphometric and genetic distances in the tested set of species. Two directions of variation in both character spaces have clearly appeared. The first direction discriminates families; the second discriminates orders. The characters responsible for these differences have been revealed. After uniting both distance matrixes, the morphological one and the molecular genetic one, into a single matrix, and displaying the summarized distances between species on a plane, the configuration of species remained principally unchanged. The principal directions of variations were preserved and marked the differences between orders, families, and genera.

[Antibodies to pathogens of Lyme's disease in patients with myocarditis and dilated cardiomyopathy]. / Antitela k vozbuditeliu bolezni Laima u bolnykh miokarditom i dilatatsionnoi kardiomiopatiei.

The paper presents the information on the involvement of the cardiovascular system in the patients with Lyme's disease as well as the results of serological investigation in patients with myocarditis and dilatation cardiomyopathy for the presence of antibodies to the causative agent of Lyme's disease with the aid of enzyme immunoassay. Out of 71 sera 3 specimens had the values of optical density higher than the upper normal limits. Based on the investigation conducted and the analysis of the clinical picture, the authors suspected a Borrelia origin of these cardiac involvements. However, to verify the diagnosis morphological examination of endomyocardiac biopsy specimens was found to be mandatory.
