“Ampicillin concentrations in pulmonary epithelial lining


“Ampicillin concentrations in pulmonary epithelial lining fluid (PELF) and plasma was studied after single intravenous ampicillin administration (15 mg/kg) or single intragastric administration of its prodrug, pivampicillin (19.9 mg/kg) to horses and discussed in relation to minimum inhibitory concentrations (MIC) of common equine respiratory pathogens.

After

intravenous administration, elimination Nutlin-3 chemical structure of ampicillin was fast and not detectable in plasma after 12 h in three out of six horses. Pivampicillin was absorbed well in non-fasted horses with an oral bioavailability of 36%. The degree of penetration of ampicillin into PELF, as described by the AUC(PELF)/AUC(plasma) ratio from 0 to 12 h was 0.40 after intravenous administration and 1.00 after pivampicillin administration.

In horses, ampicillin administered either intravenously or orally, in the form of pivampicillin, can provide clinically relevant drug concentrations in PELF

for at least 12 h, when treating susceptible equine respiratory pathogens TH-302 inhibitor (e.g. streptococci). Treatment of other bacterial pathogens requires susceptibility testing and possibly more frequent dosing, depending of minimum inhibitory concentrations (MIC) values. (C) 2010 Elsevier Ltd.

“Compound of flax/polypropylene (PP) is characterized concerning the mechanical properties of stiffness, strength, and impact in addition to the water absorption behavior. Manufacturing takes place by twin-screw extruder. The extruder screw layout is modified through different kneading elements to get high fiber aspect ratio. Sodium

hydroxide Solution was used as a washing solution for the flax fibers’ Surfaces. Both fiber and matrix are chemically modified. Selected groups of the fibers were further treated using trimethoxyvinylsilan TMVS and acrylic acid AA. The PP matrix is also treated with different Coupling agents; namely, maleated PP MAPP, TMVS-MAPP, and acrylic acid-functionalized PP AAPP, The combinations of different fiber/matrix are extruder compounded, injection molded, and finally tested. Fiber modification seems to be positive with AA-modified surface. AAPP matrix modification improves the stiffness selleck inhibitor four times that of the untreated flax/PP. Till 30 and 40 wt %, the more the fiber is the more the strength and stiffness, respectively. MAPP-modified matrix improves the mechanical properties and keeps low water absorption values. AAPP-modified matrix shows the best stiffness values. TMVS-MAPP does not secin to have distinguished improvement compared with MAPP. NaOH-TMVS/MAPP and NaOH-TMVS/AAPP systems can serve as alternatives to the normal NaOH/MAPP treatment. (C) 2008 Wiley Periodicals, Inc. J Appl Polym Sci 111: 2279-2289, 2009″
