[Nurse's evaluation of patients' problems as a methodological component in improvement of the quality of nursing care].

Nurse's diagnosis is an integral part of nursing process. Currently used methods within the framework of nursing process do not fully meet the requirements to each discipline. The authors discuss an approach to nurse's diagnosis, which will create prerequisites for developing a principally new standard approach to nurse's participation from a modern viewpoint.

[Modified method of assessing spontaneous erythrocyte aggregation].

To prevent infection of the examinees via blood during venipuncture and to simplify the method for assessment of red cell spontaneous aggregation the authors have compared red cell aggregation in venous and capillary blood. Red cell aggregation coefficients assessed by various methods in blood samples collected from the finger and vein were virtually the same; hence, this characteristics can be investigated in a capillary blood sample.
