“…The biliary drainage by T-tube or biliary fistula has been employed for studies on penicillin and streptomycin (Zaslow, Counseller, and Heilman, 1947b), tetracycline, and oxytetracycline (Herrel, Heilman, and Wellman, 1950;Danopoulos, Angelopoulos, Zioudrou, and Amira, 1954;Maynard, Prigot, and Andriola, 1954-55;Zaslow, Cohn, and Ball, 1954-55a and b;Twiss, Gillette, Berger, Aronson, and Siegel, 1956a;Uberti, 1956), chlortetracycline (Herrell and Heilman, 1949), demethylchlortetracycline (Kunin and Finland, 1959), chloramphenicol (Glazko, Wolf, Dill, and Bratton, 1949), erythromycin (Twiss et al, 1956b;Hammond and Griffith, 1961), rifamycin SV and rifamide (Fiuresz, Acocella, and Scotti, 1963;Lusena, Acocella, Baroni, and Santilli, 1963;Acocella, Lamarina, Tenconi, and Nicolis, 1966), novobiocin (Martin, Heilman, Nichols, Wellman, and Geraci, 1955), and kanamycin (Preston, Silverman, Henegar, and Neveril, 1959-60). The biliary drainage by T-tube may not allow an accurate quantitative evaluation of the recovery of the antibiotic excreted in bile owing to the incomplete external drainage of bile, although some authors maintain that the drainage of bile through a T-tube in man is virtually complete, provided that the vertical limb of the tube remains unobstructed (Rundle, Cass, Robson, and Middleton, 1955).…”
