AbstractKolmodin, G. M. and C. R. Skoglund. Influence of asphyxia on membrane potential level and action potentials of spinal moto‐ and interneurons.Acta physiol. scand. 1959.45. 1–18. — Asphyxial changes in spinal moto‐ and interneurons of decapitate cats were studied by means of intracellular microelectrodes. In both types of neurons the first change in membrane potential was usually observed after about 30 sec in the form of a depolarization of 5–10 mV which after some 30 sec was followed by a phase of more rapidly developing depolarization of larger amplitude; during recovery a phase of increased polarization may be observed. Interneurons showed signs of being more resistant to asphyxia than moto‐neurons. The spib potential underwent a. successive diminution in amplitude, at first owing to the decrease in membrane potential value, later also due to a change in spike peak level. During the later stage of asphyxia a decrease of both the rate of rise of the ascending and the rate of decay of the descending spike phases could be demonstrated. Rhythmical interneuron discharges showed periods of increased and decreased frequency before fin

摘要:

AbstractHauge, J. G. anti R. Nicolaysen. A rapid method for the study of the effect of unsaturated fatty acids on cholesterol metabolism in rats.Acta physiol. scand. 1959.45. 19–25. – A method for biological testing of the effect of unsaturated fatty acids on the cholesterol metabolism in rats is described. Pregnant mothers and the litters born are given a diet containing 10 % hydrogenated coconut oil and 1 % cholesterol. The young rats grow approximately at a normal rate the first 4 weeks of life; in the following 50 days weight increase slows down and very high liver and plasma cholesterol values result together with various symptoms of essential fatty acid deficiency. Serum cholesterol is analysed in each rat, and grouping follows according to sex and serum cholesterol values so that equal group values result for zero day. Next the fatty acids or fats to be tested are dosed in geometrically increasing doses with 10–12 rats in each group. Following two weeks daily dosing, a new blood sample is collected and the depression of serum cholesterol for each group is calculated. Liver and plasma cholesterol are approximately equally depressed, and group reductions of more than 50 % have been obs

AbstractHauge, J. Cr. and R. Nicolayses. The serum cholesterol depressive effect of linoleic, linolenic acids and of cod liver oil in experimental hypercholesterolaemic rats.Acta physiol. scad. 1959.45, 26–30. — With the aid of the method of Haugeand Nicolaysenthe serum cholesterol depressive effect of various samples of highly un saturated fatty acids or oils was studied. Linolenic acid had a stronger depressive effect than linoleic acid, and the polyunsaturated fatty acids of cod liver oil seemed to have an even stronger effect, since the effect of whole cod liver oil was at least equal to that of linolenic a
