On the tenth day of treatment, penicillin was not present in the saliva of any of the patients and was present in the tonsillar surface fluid of only one. The results suggest that measurable concentrations of penicillin in tonsillar surface fluid can only be obtained in the presence of inflammation with fluid exudation through the tonsillar epithelium.<\/jats:p>","DOI":"10.1017\/s0022215100122893","type":"journal-article","created":{"date-parts":[[2007,11,30]],"date-time":"2007-11-30T05:17:16Z","timestamp":1196399836000},"page":"309-312","source":"Crossref","is-referenced-by-count":26,"title":["Penetration of penicillin V to tonsillar surface fluid in healthy individuals and in patients with acute tonsillitis"],"prefix":"10.1017","volume":"107","author":[{"given":"A.","family":"Stjernquist-Desatnik","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P.","family":"Samuelsson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Walder","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2007,6,29]]},"reference":[{"key":"S0022215100122893_ref012","doi-asserted-by":"crossref","first-page":"1790","DOI":"10.1001\/jama.1981.03320160022023","article-title":"Penicillin V for group A streptococcal pharyngotonsillitis.
