Résumé : International audience
The strict environmental legislations and increasing ecological awareness among scientists have led to the development of “green” alternatives to mitigate corrosion. In the present work, literature on green corrosion inhibitors has been reviewed, and the salient features of our work on green corrosion inhibitors have been highlighted. Among the studied leaves, extract Andrographis paniculata showed better inhibition performance (98%) than the other leaves extract. Strychnos nuxvomica showed better inhibition (98%) than the other seed extracts. Moringa oleifera is reflected as a good corrosion inhibitor of mild steel in 1 M HCl with 98% inhibition efficiency among the studied fruits extract. Bacopa monnieri showed its maximum inhibition performance to be 95% at 600 ppm among the investigated stem extracts. All the reported plant extracts were found to inhibit the corrosion of mild steel in acid media.

Résumé : International audience
The aim of the present retrospective observational clinical study was to assess the interindividual pharmacokinetic variability of plasma concentrations of amoxicillin or cloxacillin administered in high doses intravenously in critically ill patients, related to renal function or administration method.Four hundred and two plasma concentrations were measured at steady-state with a high performance liquid chromatography technique in 162 patients treated with 100 - 300 mg/kg/day of intravenous amoxicillin or cloxacillin.For both drugs and administration methods, plasma concentrations were significantly higher for patients with creatinine clearance below 60 ml/min, even though doses were adapted for renal impairment. the correlations calculated between plasma concentrations and creatinine level, creatinine clearance or doses were all low. There were fewer outlying drug concentrations in patients receiving continuous rather than intermittent regimens.Our results are in favor of adapting dosages of these beta-lactam antibiotics based on plasma concentrations, especially in cases of renal impairment.
