    Notes: Abstract After exercise the lactate (La) removal from blood occurs significantly faster during moderate exercise than at rest. However, under both conditions there are considerable inter-individual differences in La removal. These differences in man may depend on the slow-twitch (ST) fiber content of muscle (X1), the La concentration in blood (X2), and the intensity of the recovery exercise (X3). Therefore, multiple regression models were obtained to describe La removal rates with these variables. In 10 women La concentrations were increased via a 6 min bicycle ergometer ride (87%VO2 max) and blood La concentrations were measured every 5 min during 20 min resting and active recovery periods (29–49%VO2 max). For resting recovery only the initial La concentration after the 6 min exercise provided a significant description for La removal in 8 subjects (P=0.03). However, for the active recovery a highly significant description for La removal was obtained: La removal rate (mM/l · min)=0.773×10−2X1+0.321×10−1X2−0.120×10−1X3+0.202 (R=0.91;P=0.01). The statistical independence (P〉0.10) of each of these variables in the model suggests that each is contributing uniquely to the total removal rate of La observed during an active recovery period. The relationship between La removal and %ST fibers may be related to the metabolic and anatomical features of these fibers, the La concentration probably reflects the significance of the mass action effect of La, and the intensity of exercise reflects the role of the muscle's metabolic rate. The present results illustrate that the removal of blood lactate is influenced by the interactive effects of the intensity of the recovery exercise, blood lactate concentration and the ST fiber content of muscle.

    Isolation and serological characterization of influenza A viruses from birds that were dead on arrival at Tokyo airport (1978)
    Springer

    Notes: Summary Twenty-two strains of influenza A virus were isolated from caged birds which had been imported into Japan from India and Thailand and had died during transportation to Tokyo. Serological tests divided these strains into two groups. Viruses in the first group contained Hav7 hemagglutinin and were related antigenically to A/duck/ Ukraine/1/63 [Hav7 Neq2]; viruses in the second group contained Hav4 hemagglutinin and were related to A/duck/Czech/56 (Hav4 Nav1]. All strains contained Neq2 neuraminidase that was closely related to that of A/equine/Miami/1/63 [Heq2 Neq2] and A/duck/Ukraine/1/63 [Hav7 Neq2]. It was concluded that the strains in the first group were Hav7 Neq2 and those in the second group were Hav4 Neq2; both groups of viruses showed antigenic drift from the prototype strains.

    Cholestatic liver disease associated with diphenylhydantoin therapy (1977)

    Notes: Summary A ten-year-old boy presented with a prolonged cholestatic liver disease 5 weeks after starting diphenylhydantoin therapy. The initial phase of his illness was characterized by hepatocellular damage with swollen liver cells and centrilobular cholestasis. Severe hyperlipoproteinemia with eruptive xanthomata developed within 3 weeks of his initial jaundice. The second phase of his illness was characterized by portal tract inflammation with bile ductular proliferation and chronic cholestasis gradually resolving over a period of 15 months. It is postulated that diphenylhydantoin sensitivity produced swollen hepatocytes with hypertrophy of the smooth endoplasmic reticulum, reducing hepatic sinusoidal blood flow and the clearance of secondary bile salts. A fall in clearance of lipoproteins, including the cholesterol precursor of primary bile acid synthesis, may have been responsible for a reduction in serum bile acid concentration. High levels of serum lithocholic acid, largely unsulfated presumably due to decreased hepatic uptake, may have produced the prolonged second phase of this illness when histological changes resembled that seen in experimental animals following lithocholic acid administration.

    Postprandial changes in serum concentrations of individual bile salts in normal subjects and patients with acute viral hepatitis (1978)

    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.
