Study of trace elements in BioArena system and in in vivo conditions

The adsorbent layer system is especially suitable for the biological evaluation of different compounds and trace elements as well. Present experiments showed that formaldehyde (HCHO) molecules participate in the antibiotic activity of Cu (II) ion, an „old antibiotic”. The elimination of HCHO from the chromatographic spots (e.g. by reduction or capturing) resulted in a characteristic decrease of the antibiotic effect of trace elements. The trace elements are HCHO carriers and generate a double effect (first step: deprivation of HCHO as also biological effect; second step: release of HCHO with big killing activity). These features offer good opportunities for influencing fundamental biochemical pathways. It has been established that the trace elements (mainly transition metal ions as e.g. Ni(II) ion) always generate quadruple, bioequivalent, specific immune-stimulating activity in plants with a non-linear dose-response. HCHO and its reaction products (mainly O3) are responsible also for this latter activity

HPLC analysis in drug level monitoring of K027

HPLC monitoring of pharmacokinetics was done in two body compartments of rats following intramuscular treatments with three different doses of K027, a bispyridinium mono-aldoxime type of antidotes to organoposphate intoxicated subjects. Reversed-phase HPLC separation with electrochemical detections was done to monitor the onset, the maximum level, and offset in K027 concentration. Serum level of K027 showed a fast onset, independently from the doses of K027. Drug level in brain was showing an essentially delayed kinetics
