[Data on artifical rearing of dual-purpose calves belonging to the dairy-beef type. 2. Effect of single or twice daily milk feeding and omission of Sunday milk feeding].

The authors carried out a 2x2 factor trial to investigate in which way different regimes of drinking and the feeding of a concentrate mixture at 2 levels of nutrition would affect the general development, food consumption and nutrient utilization of the calves or would influence their state of health and their behaviour in the period of milk feeding, and after weaning, up to the age of 6 months. No significant differences in the average liveweight were noted between th groups of calves that were milk fed once or twice daily and those milk fed once or twice daily with the exception of Sundays. The feeding of 2 types of concentrated food significantly influenced the liverweight of the calves only at the time of weaning. Significant differences in weight increases were only noticed with regal to the average daily weight increases until weaning, i.e. between the groups of animals receiving milk feeds twice daily, with the exception of Sundays, and the groups fed different types of concentrate mixtures. The different kinds of feeding did not influence the amount of solid food consumed by the animals, nor did it affect the level of nutrient utilization and the general behaviour of the animals. It was found that in the animals receiving milk once daily,except Sundays, the symptoms of diarrhea observed in the early phase of milk nutrition disappeared more slowly than in the outher animals.

Primary purulent meningococcal pericarditis with tamponade.

A case of primary purulent meningococcal pericarditis, presenting with hemodynamic derangement due to tamponade, is reported. Treatment was successfully fulfilled with antibiotics and surgical drainage, using continuous percutaneous subxiphoidal catheter drainage with the Seldinger technique. Less than ten cases of this potentially lethal entity have been reported in the literature.

Reverse-phase chromatography of polar biological substances: separation of catechol compounds by high-performance liquid chromatography.

Catecholamines and their metabolites have been separated isocratically by reverse-phase chromatography with aqueous (no organic solvent admixed) eluents. Unlike ion-exchange or ion-pair chromatography, mixtures of both acidic and basic substances can be separated in a single chromatographic run, because the retention is governed by hydrophobic interactions between the nonpolar moiety of the solute molecules and the octadecyl-silica stationary phase. The relative retention values strongly depend on the pH of the eluent, which governs the degree of dissociation of ionogenic solutes. The reproducibility of the results and the stability and efficiency of the chromatographic systems make this approach particularly attractive for use in clinical analysis.
