    Notes: Abstract A sensitive gas-liquid chromatographic assay has been used to analyze serum concentrations of the four major bile acids in both sulfated and nonsulfated forms. Twelve control subjects have been compared with 40 patients with acute viral hepatitis whose symptoms had been present from 6 to 34 days. In all subjects blood samples were collected fasting and 2 hr after a standard meal. In addition half-hourly samples were assayed for 3 hr after the meal in 6 controls and 5 patients with acute viral hepatitis. In both the control and hepatitis groups, serum concentrations of nonsulfated bile acids, especially cholic and chenodeoxycholic acids, increased after the meal. The peak levls usually occurred between 60 and 120 min in the half-hourly studies. In contrast, sulfated bile acids fell in both groups with minimum levels 60–120 min after the meal. Serum total bilirubin, aspartate aminotransferase, and alkaline phosphatase concentrations in hepatitis patients correlated significantly with postprandialitotal bile acid concentrations but were more frequently abnormal than serum total or individual bile acids. Unconjugated bile acids were not detected in control subjects but were found in 17 of the 40 hepatitis patients. Significantly higher levels of sulfated bile acids and chenodeoxycholic acid were present in hepatitis patients compared to controls. In this group of patients with acute viral hepatitis, studied soon after presentation to hospital but in some cases, some time after the onset of their disease, measurement of serum bile salts was not helpful as an index of hepatocellular function. Postprandial variation in the time of peak concentrations of the individual bile acids resulted in the postprandial bile acid studies being no more useful than fasting assays in distinguishing patients with acute viral hepatitis from control subjects.

    Description / Table of Contents: Résumé Anthocoris nemorum (L.) etA. nemoralis (F.) ont été élevés sur le stade aptère du puceron du houblon,Phorodon humuli (Schrank), à 20°C±0.5°C. A. nemorum etA. nemoralis ont consommé durant leur phase larvaire, en moyenne 255 et 174 pucerons respectivement, les adultes par contre ont consommé respectivement 37 et 33 pucerons par jour. Les jeunes larves consommaient de façon sélective les jeunes pucerons, tandis que les adultes et les larves au 5c stade consommaient des pucerons de toute taille. Le délai de développement entre l'émergence et la métamorphose finale pourA. nemorum etA. nemoralis fut de 22 et 16 jours respectivement.
    Notes: Abstract Anthocoris nemorum (L.) andA. nemoralis (F.) were reared on apterous hop aphids,Phorodon humuli (Schrank), at 20±0.5°C.A. nemorum andA. nemoralis killed an average of 255 and 174 aphids respectively during nymphal development, and the adults killed 37 and 33 per day respectively. Small anthocorid nymphs selectively killed small aphids but adult anthocorids and 5th instar nymphs killed aphids of every size. Mean development times from emergence to final moult were 22 and 16 days forA. nemorum andA. nemoralis respectively.
