DETERMINATION OF ANTIMICROBIAL ACTIVITY OF CHLORHEXIDINE GEL.

Many researchers have advocated in recent times that antiseptic use in healing wounds should be discouraged. Antiseptics have been found to retard healing of wounds. Poloxamer 407 shows thermoreversible properties, which are of the utmost interest in optimizing drug formulation (fluid state at room temperature facilitating administration and gel state above sol-gel transition temperature, at body temperature, promoting prolonged release of pharmacological agents).

[Antimicrobial action of ammonium salts of fused heterocycles containing ortho-nitrogen].

By alkylation of hexamethylenetetramine with halogenated derivatives of ketones, ethers, esters or amides of acids, alkyl- and aralkyl halides the corresponding N-monoalkylated compounds of hexamethylenetetramine were obtained. The quaternization of pyridine nitrogen in 5,6-benzoquinoline, 8-hydroxyquinoline, quinoline, 1,10-phenanthroline molecules with alkyl- or aralkylhalides was carried out. The susceptibility of Gram-positive (Streptococcus agalactiae and Staphylococcus aureus) and Gram-negative (E.

[Preparation, analysis and anti-anemic action of peroral powders with ferrous oxalate. Ferosol. 2].

Experiments with piglets showed good assimilation and metabolism of iron (II) in antianaemic powder Ferosol-1. In order to improve this drug, manganese, calcium (Ferosol-2, 1 composition) and ascorbic acid (Ferosol-2, 2 composition) were added. Manganese and ascorbic acid stimulate erythropoiesis and being strong reductants stabilize iron (II) on storage and in gastrointestinal tract.

[Preparation, analysis and anti-anemic action of peroral powders with ferrous oxalate. Ferosol-1].

Investigation of new stable iron (II) compounds is still an actual problem of today. Therefore we synthesized ferrous oxalate and prepared a stable antianaemic powder Ferosol-1 including copper, zinc and cobalt. We used colour tests, precipitation reactions and paper chromatography for identification of components of this powder.
