According to the WHO, the secondary form of hematopoietic-depressive status increases the risk of death in people with oncological, infectious, and hormonal diseases. The choice of drugs that stimulate the hematopoietic activity of B-lymphopoiesis is limited. The current leucopoiesis drugs have a number of side effects: thymic preparations stimulate the production of PGE2, which causes chronic inflammation and various autoimmune diseases through the differentiation of T helper 1 (Th1) cells, the proliferation of Th17 cells, and the production of IL-22 from Th22 cells through EP2 and EP4 receptors; cytokine preparations can cause uncontrolled immune reactions and impaired contractility of smooth and cardiac muscles; drugs based on nucleic acids can stimulate the division of all cells, including bacterial and cancerous ones.

Errors associated with the concentration of epinephrine in endonasal surgery.

Eur Arch Otorhinolaryngol

Department of Otolaryngology, University Hospital Ostrava, 17 listopadu Street 1790, 708 52 Ostrava, Czech Republic.

This paper presents two cases of using erroneous concentrations of epinephrine during endonasal surgery. The two patients discussed were part of a larger study aimed at monitoring the absorption of epinephrine upon injection into the nasal mucosa. During this study, we observed major cardiovascular reactions in two consecutive patients--ventricular tachycardia with ventricular extrasystole and a significant rise in systolic and diastolic blood pressure and pulse rate.

[The antiarrhythmic activity of the trimecain ammonium derivative in myocardial ischemia].

Eksp Klin Farmakol

November 2003

Department of Pharmacology, Mordvinian State University, ul. Bol'shevistskaya 68, Saransk, Mordvinia, 430000 Russia.

The results of experiments on cats and dogs showed that quaternidine, a quaternary ammonium derivative of trimecaine, exceeds the structural precursors (trimecaine and lidocaine), as well as the reference drugs quinidine and propranolol, in intensity of the antiarrhythmic action upon single administration on the occlusive and reperfusive arrhythmia models. The therapeutic effect of quaternidine in animals with acute myocardial ischemia lasts for about 8 h, which more than 20 times longer as compared to the duration of action of both lidocaine and trimecaine.
