Antimicrobial susceptibility testing of Helicobacter pylori determined by microdilution method using a new medium.

Antibiotic susceptibility testing of Helicobacter pylori isolates was performed by broth microdilution method with MegaCell RPMI-1640 Medium (SIGMA). Fifty five clinical isolates of H. pylori were tested against metronidazole, tinidazole, amoxicillin, and clarithromycin.

In vitro antimycotic activity and nail permeation models of a piroctone olamine (octopirox) containing transungual water soluble technology.

Several in vitro studies with a new medical device (Myfungar) containing 0.5% of piroctone olamine (CAS 68890-66-4, octopirox) in a hydroxypropyl chitosan hydroalcoholic solution were performed. The chemical name of the active ingredient is 1-hydroxy-4-methyl-6 (2,4,4-trimethylpentyl)-2(1H)-pyridone; combination with 2-amino-ethanol (1:1).
