    Notes: In 77 consecutive patients with grass pollen rhinitis as the only allergic disease, treatment with sodium cromoglycate (SCG) nasal spray, hyposensitization with aluminium hydroxide adsorbed extract of grass pollen as perennial treatment, and a combination of the two was compared. Specific serum-IgE, IgG and IgG4 were determined in patients who participated in three consecutive seasons. Significant immune response was found in the hyposensitization group, but not in the group treated with SCG. No correlation between the immunoglobulin responses and the individual symptom and/or medicine scores was found. Symptom and medicine scores were analysed in the 3 weeks with the highest pollen counts each year during 4 consecutive years. Higher scores were found in the group treated with sodium cromoglycate compared with the other two groups, but the difference was only significant for eye and total symptoms in the first season. None of the groups, however, suffered from more than mild to moderate symptoms even in the weeks with peak pollen counts. A significantly larger decrease in the wheals of the skin prick test was shown during hyposensitization than during treatment with SCG. No difference was found in the frequency of patients who became symptom-free or developed pollen asthma.

    Notes: Six male well trained cross-country skiers were exposed to 6 d of training 4 h/d at an altitude of 2700 m. Living quarters were at 2000 m. Measurements of serum-erythropoietin concentration ([EPO]), erythrocyte- 2,3 diphosphoglycerate (DPG), haemoglobin (HB), packed cell volume (PCV), body mass (BM) and resting heart rate (HR) were made before, during and after moderate-altitude training. Total body haemoglobin (THB) was determined before and after altitude training. Plasma volume (PV) was calculated from THB, PCV and HB. The daily EPO production was calculated from [EPO] and PV. Moderate-altitude EPO production at days 2, 3 and 6 was significantly higher than prealtitude levels. DPG increased significantly at moderate altitude. Pre-altitude and moderate-altitude EPO production vs DPG were correlated. Moderate-altitude levels of BM decreased, PV increased and HB decreased (NS). During moderate-altitude training, DPG exerts a certain feedback regulation of EPO production. The temporal courses of [EPO] and EPO production at moderate altidude are not affected by variations in PV.

    Notes: The general applicability of the square root model to describe gastric evacuation in predatory gadoids independently of meal size was verified through experiments on whiting Merlangius merlangus, saithe Pollachius virens and cod Gadus morhua fed different fish and crustacean prey. Gastric evacuation rate was related by a negative power function to energy density of fish prey over an extended range from 3·4 to 11·5 kJ g-1 of the effector variable. Gastric evacuation of crustacean prey seemed to depend on the characteristics of their exoskeleton. Gastric evacuation of mixed meals composed of fish prey with different energy densities could be described as a function of the overall energy density. The evacuation rate of each of the prey could be described directly by their share of the stomach content. A full gastric evacuation model including predator size, temperature and prey energy density was established for whiting, saithe and cod. It was demonstrated that estimates of food rations might be severely biased by use of mean values for prey composition and total mass of stomach contents.

    Notes: No effect of prey size on gastric evacuation rate was found in whiting Merlangius merlangus.Prey energy density explained most of the data variation among fish prey, and evacuation time increased by a factor 1·6–1·7 with prey energy density increasing from 3·4 to 5·6 kJ g−1. The power model expanded to include predator size, temperature, and prey energy density could describe gastric evacuation in whiting fed fish prey. Krill Meganyctiphanes norvegica was evacuated at a rate similar to fish prey of equal energy density, while the evacuation of brown shrimp Crangon crangon took almost twice as long.

    Notes: Gastric evacuation experiments were performed on whiting Merlangius merlangus fed discrete meals of different sizes. Herring Clupea harengus, sandeel Ammodytes tobianus, common goby Pomatoschistus microps, and brown shrimp Crangon crangon were tested as prey. A simple power model to describe gastric evacuation was evaluated and compared with a power model expanded as a function of meal size. The model parameters were estimated by means of nonlinear least squares. When all meal sizes were included the estimates of the power (curvature) parameter in the expanded model were within the range 0·36–0·77 for the different prey. The power estimates in the simple model were generally close to 0·5. The exception was crustacean prey, which gave a higher value. In the simple model the power estimate represents a compromise between the curvatures of the curves fitted to the observations for each meal size and the relationship between meal size and overall evacuation rate. Compared with an expanded model a simple model with a power value of 0·5 gave a suitable description of the gastric evacuation of fish prey independent of meal size. The variation of data was proportional to meal size, and this could be taken into account in the estimation procedure by expressing stomach contents relative to meal size.
