    Notes: Summary The urinary and biliary excretion of diflunisal and its glucuronide and sulphate conjugates were studied in 10 patients following cholecystectomy. Total urinary excretion (0–24 h) was 36.6±16.4% of the 250 mg dose. Biliary excretion (0–24 h) was restricted to the phenolic and acyl glucuronides and accounted for 3.7±2.3% of the dose. An inverse relationship existed between urinary and biliary excretion of diflunisal and its conjugates. The data indicate that the reduced plasma clearance of diflunisal in patients with renal failure may, at least in part, be due to increased biliary excretion of diflunisal glucuronides followed by hydrolysis in the gut and reabsorption of diflunisal i.e. enterohepatic cycling.

    Notes: Abstract Primordial shoot explants excised from buds of one Larix decidua tree, about 30 years old, produced more adventitious buds, elongating into shoots, when grown on half strength Litvay medium than when grown on other basal media. Thidiazuron and N6-benzyladenine (BA) were equally effective in adventitious bud induction. In a comparative study of 30-year-old L. decidua, L. leptolepis, L. eurolepis, and L. laricina trees, explants from L. eurolepis and L. decidua produced a high number of cultures with adventitious buds that elongated into shoots; those from L. leptolepis were less productive, and those from L. laricina failed to form adventitious buds. The highest response was obtained with material collected in August and September, and in March and April; the lowest response occurred in explants from the October collection.
