[Diagnosis and therapy of ethylene glycol poisoning--analysis of 20 patients].

The paper presents a retrospective analysis of 20 patients with acute ethylene glycol intoxication who were treated from 1972 to 2001 in the Dialysis Centre of the IVth Medical Clinic and from 1997 at the L. Pasteur Nephrological Clinic of the Faculty Hospital and Safarík Medical Faculty in Kosice. The ethylene glycol intoxication was manifested by neurological symptoms, extreme metabolic acidosis, acute toxic hepatitis and acute renal failure.

[Multidrug resistance and the P-glycoprotein].

A survey is presented on the information concerning the nature and molecular mechanism of multi drug resistance, a phenomenon involving the resistance of tumor cells to different types of chemotherapeutic agents. P-glycoprotein is by its enzymatic activity directly responsible for expelling xenobiotics from the intracellular space and thus also for the development of MDR. Its detection provided new possibilities for causal studies of this type of resistance as well as for its in vitro modelling.

Peroxidase labelled monoclonal antibody against light chains of human cardiac myosin.

Monoclonal antibody against light chains of human cardiac myosin (MLC) was labelled with horseradish peroxidase. The conjugation was performed by two different methods with glutaraldehyde and periodate respectively. The binding activities of the conjugates were tested by enzyme linked immunosorbent assay (ELISA) on the microtitration plates with immobilized MLC (1-1000 ng per well).
