La tétracycline, connue sous le nom commercial Sumycin, agit en bloquant la fixation de l’ARNt sur la sous-unité 30S ribosomale, interrompant l’élongation de la chaîne protéique bactérienne. Ce mécanisme confère une activité sur un spectre large, incluant bactéries Gram positives, Gram négatives, rickettsies et spirochètes. Sa biodisponibilité digestive varie selon la prise alimentaire et les interactions avec les ions divalents comme calcium et magnésium. Sa diffusion tissulaire est importante, notamment dans les voies respiratoires et génito-urinaires. L’élimination se fait par voie rénale et biliaire. Les effets indésirables incluent photosensibilisation, troubles digestifs et coloration dentaire en cas d’administration précoce. Les guides thérapeutiques mentionnent sumycin prix, en soulignant la nécessité de restreindre son utilisation afin de limiter les résistances acquises.

In the early part of the present year the H onorary S ecretary was informed that it was proposed to remove the Lancash ire portion o f the R ichmond Wills to York (where the Y orksh ire portion had already gone), and upon inquiry at the Principal Probate Registry it was found that the removal to Y ork of the remaining R ic h mond Wills had been authorised but not yet c a rried out. Strong protests were at once made by this Society and other Archaeological Societies, to the President of the Probate D iv ision and also to the R oyal Com m issio ners now sitting to inquire into the custody and preservation o f public records, and it is satisfactory to be able to state that in c o n se q u e n c e o f these protests it was decided in February last that the R ich m o nd Wills, other than those o f the Y orksh ire D e a n erie s, should T h is volume also includes a list o f the Wills proved within the Peculiar of the M anor of H alto n for the same p erio d. are very few, and since the death o f William Bradshaw , Esq.
