    Notes: Summary In previous studies cytomegalovirus (CMV) infection was identified as one risk factor in the development of vanishing bile duct syndrome (VBDS) after orthotopic liver transplantation (OLT), but its precise role in relation to the pathogenesis of tissue damage is uncertain. In the present study a-interferon (α-IFN) expression in the liver was studied as an indirect marker of viral infection in serial liver biopsies from 42 patients following OLT. α-IFN was identified more frequently in the bile duct cytoplasm of patients developing VBDS, with or without evidence of preceding CMV infection (7/8 and 4/5 cases, respectively), when compared with patients with acute CMV but without evidence of VBDS (6/19 cases; P〈0.05) or those with neither complication (2/10 cases; P〈0.01). α-IFN was detectable in bile duct cytoplasm for a longer period in patients developing VBDS than in those with acute CMV infection alone (median 14 weeks and range 9–19, median 6 weeks and range 1–11 weeks, respectively; P〈 0.025). These data indicate that persistent CMV infection of bile duct cells is a likely co-factor linked to progression to VBDS, but the processes that allow persistent viral infection and bile duct destruction remain to be determined.

    Notes: Summary The effect of treatment for eight weeks with isradipine 1.25 mg twice daily for 4 weeks and thereafter 2.5 mg twice daily for 4 weeks on ex vivo platelet function was investigated in 10 male hypertensive patients, aged 51 (6.1) y. Systolic and diastolic blood pressure, platelet aggregation in response to ADP, serum thromboxane B2 and β-thromboglobulin levels were significantly decreased at rest before exercise ergometry, during exercise and at rest after exercise. The platelet count, platelet sensitivity and the plasma levels of 6-oxo-prostaglandin F1α were not affected by isradipine. It is concluded that a compound that lowers blood pressure and inhibits platelet activation may be of clinical benefit in the routine treatment of hypertension.

    Notes: Summary (1) The mean cumulative urinary digoxin excretion over 8 days was compared in 8 healthy volunteers after single doses of digoxin administered as 3 Lanoxin tablets of 0.25 mg, 3 digoxin tablets of 0.2 mg, 12 Lanoxicaps without sorbitol of 0.05 mg, 6 Lanoxicaps without sorbitol of 0.1 mg digoxin, 3 Lanoxicaps without sorbitol of 0.2 mg and 3 Lanoxicaps with sorbitol of 0.2 mg. (2) There was no significant difference between the 8 day cumulative urinary excretion for any of the Lanoxicaps treatments. (3) Cumulative urinary excretion after 3 digoxin tablets of 0.2 mg was significantly (P〈0.05) lower than after all other treatments. (4) Cumulative urinary excretion after 3 Lanoxin tablets of 0.25 mg was not significantly different from that after any of the Lanoxicaps treatments except 0.1 mg Lanoxicaps without sorbitol, it was significantly (P〈0.05) lower after the latter. (5) Mean urinary excretion of digoxin was 60% of ingested dose for all Lanoxicaps treatments and was significantly (P〈0.05) higher than the mean value of 50% for both tablet treatments. (6) Enhanced absorption of digoxin from Lanoxicaps was confirmed and shown to be unrelated to the sorbitol content of the capsule shell.
