[Development of program therapy for patients with acute myeloid leukemia under the age of 60 years, based on the principles of differentiated effects].

Aim: To analyze the results of treatment in patients with acute myeloid leukemia (AML) within protocols AML-17 and modified AML-17 (mOML-17) as part of two consecutive pilot studies in order to develop the best treatment strategy for AML patients aged below 60 years.

Materials And Methods: The study included 89 AML patients who were aged below 60 years and received treatment within the AML-17 and mOML-17 protocols. Cytogenetic and molecular genetic studies were performed in all patients.

Divergent Dimethylarginine Dimethylaminohydrolase Isoenzyme Expression in the Central Nervous System.

The endogenous methylated derivative of ʟ-arginine, N,N-dimethyl-ʟ-arginine (asymmetric dimethylarginine, ADMA), an independent risk factor in many diseases, inhibits the activity of nitric oxide synthases and, consequently, modulates the availability of nitric oxide. While most studies on the biological role of ADMA have focused on endothelial and inducible nitric oxide synthases modulation and its contribution to cardiovascular, metabolic, and renal diseases, a role in regulating neuronal nitric oxide synthases and pathologies of the central nervous system is less understood. The two isoforms of dimethylarginine dimethylaminohydrolase (DDAH), DDAH1 and DDAH2, are thought to be the main enzymes responsible for ADMA catabolism.

[Correction of hemodynamics and heart rate disorders in paitients with right coronary artery disease].

Purpose Of The Study: To analyze a correlation between sino-atrial node automatic activity and atrio-ventricular conductivity in patients with lower acute myocardial infarction (AMI) and atrio-ventricular blockade II-III (AVB) during infusion therapy.

Materials And Methods: Retrospective analysis of care for patients with AMI and AVB was carried out. Infusion therapy effects were studied in 12 patients with right coronary artery disease and AVB.
