    Notes: Relative sheep production from Aurora (very early flowering), Mellra (late-flowering tetraploid) and Aberystwyth S23 (late flowering) perennial ryegrass (Lolium perenne L.) varieties was compared during harvest years 4-6 (1988-90) as grass only (200 kg N ha−1) and grass/clover (75 kg N ha −1 in 1988, 0 kg N ha−1 in 1989 and 1990) at Bronydd Mawr Research Centre (310-363 m) in mid-Wales. The pastures were continuously stocked with Beulah Speckled Face ewes and their Suffolk cross lambs from spring to mid-July. From late July to early November only the weaned lambs grazed the swards.Mean (1988-90) total annual lamb production per hectare from Aurora and Meltra was 70% and 16% more than that from S23. However, the difference between both varieties and S23 was much greater as grass/clover (Aberystwyth S184 small-leaved type) than as grass-only swards. Differences between the grasses in individual lamb growth rates were most pronounced during the post-weaning period, when that on Meltra was 38% and 23% more than on Aurora and S23 respectively.Mean annual lamb output from grass/clover swards was only 70% of that from grass-only swards during the 2 years when the former swards received no fertilizer N. Averaged over the 3 years (1988-90) individual lamb liveweight gain post weaning was 38% higher on grass/clover than on grass-only swards.The results are discussed in relation to those for the first 3 harvest years (1985-87). It is concluded that, although Aurora was less persistent than both late-flowering varieties, its superiority in providing an average of 29% more lamb output than S23 during the critical spring period (up to early June) would be of considerable practical significance in upland sheep systems, as would be the overall superiority of the tetraploid Meltra over S23.

    Adult respiratory distress syndrome following cardiopulmonary bypass: incidence and prediction (1992)

    Notes: The outcome of adult respiratory distress syndrome complicating cardiopulmonary bypass has changed little in recent years. A retrospective, case-controlled study was designed to assess the incidence of the adult respiratory distress syndrome in these circumstances and the extent to which it could be linked with pre and peri-operative predictive factors. Eleven patients who developed the syndrome out of 840 who underwent cardiopulmonary bypass over a 9 month period were compared with 53 controls matched for sex, operation and surgeon. The incidence of adult respiratory distress syndrome and its mortality were 1.3% and 53% respectively. Significant predictors were a high intra and postoperative intervention score, the total volume of blood pumped during bypass (〉300 l) and age (〉60 years). These risk factors should alert the clinician to the possibility of severe postoperative pulmonary complications.

    The use of radionuclide techniques in the assessment of alveolar-capillary membrane permeability on the intensive care unit (1990)

    Notes: Conclusion Three isotopic methods of estimating alveolar-capillary membrane permeability have been described. The first, radiolabelled HSA, is crude, and appears to have no clinical applications. Pulmonary99mTc-DTPA clearance studies are relatively easy to perform, but suffer from their high sensitivity and variations in technique from centre to centre. The double isotopic measurement of PAI has only been adopted by a few centres, but may offer reliable assessment of the pulmonary endothelial permeability which is probably an early marker of acute lung injury. None of these techniques has proved predictive of outcome in ARDS. However, trials where alveolar-capillary membrane permeability is assessed before clinical evidence of lung injury is apparent have yet to be conducted. Thus at present, methods of assessing alveolar-capillary membrane permeability, particularly capillary endothelial integrity, may prove to be more useful in monitoring new therapeutic interventions in lung injury, rather predicting outcome.

    Rust-red grain beetle,Cryptolestes ferrugineus, and flat grain beetle,Cryptolestes pusillus: Antennal and behavioral responses to synthetic components of their aggregation pheromones (1990)

    Notes: Abstract Antennal and behavioral responses of the rust-red grain beetle,Cryptolestes ferrugineus, and the flat grain beetle,C. pusillus, to synthetic samples of the macrocyclic lactones reported to comprise their aggregation pheromones were investigated. Electroantennogram (EAG) recordings were obtained successfully from both species for the first time. Females of both species showed larger EAGs than males. The EAGs ofC. ferrugineus showed a high degree of specificity for conspecific aggregation pheromone components;C. pusillus showed much less specificity. Behavioral tests were conducted using two-choice pitfall bioassays. Separation of the results into the two effects of activity stimulation and direction finding showed that both effects contributed to the overall response, although sometimes to different extents. The strain ofC. pusillus studied responded equally well to both components of its pheromone, whereas it had been reported previously that only one was active, the other acting as a Synergist and eliciting no response when tested alone. With both species, behavioral response was elicited with a single lactone, suggesting that it might not be necessary to use both components for field use. Particularly surprising was thatC. pusillus showed a greater response to the pheromone components ofC. ferrugineus than to its own. Aeration of the two species and thermal desorption of the collected volatiles confirmed production of the expected lactones, and aeration of authentic lactones showed that the response was not due to the C.ferrugineus pheromone components being markedly more volatile. This response, which seems to be an actual preference, is the first to be discovered among the cucujid beetles and encourages optimism that a practical lure for various species may not need to be as complex as originally feared.

    The neglected bulimic: The nonpurger (1990)

    Notes: Abstract For nearly 10 years bulimia has been recognized officially as a distinct eating disorder, and yet in that time only minimal attention has focused on the nonpurging subtype. The present investigation compared 21 DSM-III-R diagnosed nonpurging bulimics with 22 non-eating-disordered controls on three standardized questionnaires and during a unique assessment task. In this procedure subjects imagined that they were the character in a series of slides and audiotaped flooding scenes. The content of the stimuli ranged from food and weight cues to issues hypothesized to play a role in the development or maintenance of bulimia (e.g., rejection or loss of control fears). A MANOVA conducted on the three questionnaires was highly significant, with the Beck Depression Inventory and the Restraint Scale being responsible for the elevated bulimic scores. A repeated-measures ANOVA performed on the self-report ratings during the exposure task also achieved significance, as the bulimics reported higher anxiety reactions than controls to each experimental stimulus. Significant skin conductance reactions were detected when a group of only the most psychophysiologically responsive bulimics and controls were compared. The importance of continued comprehensive evaluations with DSM-III-R nonpurging bulimics was emphasized.
