    Notes: This study investigated the discrepancy between parental reports indicating a high prevalence of feeding problems during infancy and the relatively low identification rate of such cases at child health care centers. Thirty nurses were interviewed about definitions, prevalence, causes, and interventions for such problems. Thereafter, they were retrospectively asked about presence of feeding problems in 30 infants, for whom parents had reported existence of feeding problems, and in 30 control infants. A group (n=22) based on parent-nurse agreement about the existence of a problem was compared with a group (n= 8) identified as problematic by parents only and with the control group. The parent-nurse agreement group stood out as more burdened: infant growth was affected, there had been feeding history problems (breastfeeding, weaning and protracted meals) and the level of parental concern was higher. More infant respiratory infections were reported, and more medication had been prescribed for this group. Although nurses seemed to rely to a great extent on parental reports in identifying feeding problems, the present results suggested that the parent-nurse discrepancy in identification rate may occur due to nurses' weighting of parental complaints with other factors such as the child's general condition and the family social situation.

    Notes: A total of 12 reindeer calves were divided into two groups and the volume densities of liver cytoplasmic structures were counted using TEM. The six animals in group 1 were allowed to graze freely while those in group 2 were kept in pens and fed with lichens. All of them had a negative energy balance and lost weight from November to April, group 1 by 14.9% and group 2 by 24.8%. In spite of the weight losses, no significant changes in volume densities occurred during the winter. Glycogen remained fairly steady and there was no fatty infiltration into the hepatocytes. The very low incidence of Golgi apparatus in the hepatocytes may have been due to the inhibition of protein and lipid synthesis during the winter. These results point to substantial adaptation to extreme environmental conditions. The animals in group 1 apparently moved about more, which may have caused a greater breakdown of glycogen, resulting in turn in a lower volume density of glycogen in January and March.

    Notes: This communication describes the ultrastructure of the ependyma of the bovine area postrema. The polygonal cells possessed an abundant apical array of microvilli but were nonciliated with the exception of occasional cells at the periphery of the area, which had a central kinocilium. The low squamous cells contained moderate numbers of cytoplasmic organelles. The cells do not appear to be typically secretory, but may function in fluid exchange.

    Notes: Summary A new histochemical method for light microscopic demonstration of liver glycogen phosphorylase activity has been introduced in this study. The method demonstrates phosphorylase activity by precipitating phosphate ions, liberated in the reaction catalyzed by the enzyme, with Fe++ present in the incubating medium. The precipitate is visualized as ferrous sulphide. The new glycogen, formed in the same reaction, can also be demonstrated in this method after staining with iodine. The lobular localization of the reaction products obtained according to this method in the liver, corresponds well to that obtained according to earlier methods for the demonstration of only new-formed glycogen.

    Notes: Abstract Barbiturates are used clinically as anaesthetics and to reduce raised intracranial pressure. One side effect is hypotension, usually ascribed to a depression of cardiac contractility, while their effects on the resistance vessels are more controversial: both vasodilation and vasoconstriction have been described. This study analyzes the effects of thiopental on basal vascular tone in the cat skeletal muscle. We found that total resistance increased by almost 20% at low (50μmol/l) and decreased down to about 50% of control at high (350 μmol/l) plasma concentrations of thiopental. The vasoconstriction dominated in the large arterioles (i.d. 〉25 μm) and the vasodilation in the small arterioles (i.d. 〈25 μm). A dosedependent inhibition of myogenic vascular reactivity (here defined as the maximum resistance increase to a transient rise in transmural pressure) coincided with the vasodilation. Autoregulation of blood flow was depressed by thiopental. During vasoconstriction there was a net transcapillary fluid absorption and during vasodilation a net fluid filtration. The fluid movements could be ascribed to variations in capillary hydrostatic pressure. If applicable to the cerebral circulation these results suggest that thiopental at high plasma concentrations might induce, instead of reduce, interstitial brain oedema.
