Metronidazole Bioassay [PDF]

Antimicrobial Agents and Chemotherapy, 1976
Urine from patients receiving metronidazole [1-(2-hydroxyethyl)-2-methyl-5-nitromidazole] orally or per vagina were subjected to paper chromatographic fractionation and examined for anticlostridial activity. Unmodified metronidazole and several metabolites were detected.

Exposure of Rats to Multi-Walled Carbon Nanotubes: Correlation of Inhalation Exposure to Lung Burden, Bronchoalveolar Lavage Fluid Findings, and Lung Morphology

Nanomaterials, 2023
To evaluate lung toxicity due to inhalation of multi-walled carbon nanotubes (MWCNTs) in rats, we developed a unique MWCNT aerosol generator based on dry aerosolization using the aerodynamic cyclone principle.

Ticarcillin Bioassay [PDF]

Antimicrobial Agents and Chemotherapy, 1981
An accurate, plate diffusion bioassay for ticarcillin, utilizing the fast-replicating Beneckea natriegens and 4% salt agar, is described in this report. Zones of inhibition were well defined after 3 h, and the limit of sensitivity was around 5.0 μg/ml.
