(author), TNO Preventie en Gezondheid (author)Background/Aims: Bile flow consists of bile salt-dependent bile flow (BSDF), generated by canalicular secretion of bile salts, and bile salt-independent flow (BSIF), probably of combined canalicular and ductular origin. Bile salt transport proteins have been identified in cholangiocytes, suggesting a role in control of BSDF and/or in control of...article 2005

van Raaij, J.A.G.M. (author), Kaptein, E. (author), Visser, T.J. (author), van den Berg, K.J. (author), Medisch Biologisch Laboratorium TNO (author)Metabolism of thyroid hormones was investigated in WAG/MBL rats that had been exposed to hexachlorobenzene (HCB). Serum thyroxine (T4) levels were lowered by 35.5%, whereas triiodothyronine (T3) levels were not changed. Bile flow, as well as T4 excretion in bile were increased by HCB treatment. Analysis of bile by HPLC revealed a more than 3...article 1993

Instituut voor experimentele gerontologie TNO (author), Kitani, K. (author), Sato, Y. (author), van Bezooijen, K. (author)The biliary excretion of digitoxin (Dt3) and its metabolites was studied in female BN/Bi rats of different ages ranging from 3 to 30 mth. The disappearance of radioactivity from plasma after an i.v. injection of [3H]Dt3 (0.01 mg/100 g body weight) gradually slowed as rat age advanced. The 2-h biliary recovery of radioactivity (percent of the...article 1982
