Nutritional and Physiological Value of Gums

Abstract Electrocardiographic examinations were performed on 45 Silesian breed horses (group K, 3-16-year-old, 16 stallions, 29 mares) and on 25 Polish Primitive breed horses (group P, 1.5-19-year-old, two stallions, six geldings, 17 mares). Einthoven and chest leads were used. P-wave dispersion was electronically evaluated. There was no correlation between P-wave dispersion and other ECG parameters, age, sex, body mass, or month of pregnancy. The average value of P-wave dispersion for all horses was 30.77 ms (SD 3.92 ms), however in particular groups it was: in group P - 31.89 ms (SD 3.07 ms), and in group K - 30.15 ms (SD 4.27 ms). The maximum value of P-wave dispersion in the studied population was 40 ms, in groups P and K - 37,6 ms and 40 ms, respectively. The physiological value of P-wave dispersion for the group of horses was below 45 ms.

Physiological Value

Physiological value is one of the factors affecting the effectiveness of human activities. Currently, there is no single approach to assess the physiological value of human behavior. The article presents data on the role of the physiological cost of human activity, estimated by the indicators of mathematical analysis of heart rate, in the reproduction of matrix visual images. The article puts forward the position that the physiological cost of activity is an important factor in the formation of unequal performance. At the same time, the physiological cost is reflected not only in shifts in a number of physiological indicators when the subjects perform a particular activity, but in the nature and levels of expression of correlation relationships between indicators of this activity and indicators that reflect physiological changes in the body at the same time.

This work is consered with the processing value of Elderberry fruit (berries) from domestic plantation selection (Horgos region). Chemical analyses of reference parameters (dry matter, acidity, pectin, pectic acid, protopectin, Capectat, ash, cellulose, total and reducing sugars, mineral substances, proteins and aminoacids, surface color, anthocyanins and vitamin C) confirmed high nutritional and physiological value of samples and full validity of work on this selection and production in plantation conditions.

Physiological Value

Abstract A RECENT communication (6) has shown by several different means that rubber present in the living plant actually disappears under seasonal and other conditions in the life of the plant, and that it can, therefore, no longer be regarded as an excretory product of metabolism of no physiological value to the plant. The results recorded were obtained in a study of the rubber content of Parthenium argentatum, but they will undoubtedly be found to hold for Hevea brasiliensis when suitable methods of investigation are developed for the latter. The importance of these findings in relation to the economic development of rubber is obvious and far-reaching. They have already been applied in the cultural development and exploitation of Parthenium argentatum. On the scientific side they suggest a more intimate study of the behavior of the rubber hydrocarbon towards oxidation-reduction processes occurring within the living plant and to the effect of such agencies on the rubber itself in vitro. That rubber is readily attacked by oxidizing agents in general is now well known. But even the classical researches of Harries on the products of decomposition of the rubber hydrocarbon by means of ozone (1) have thrown little light on the ways and means by which the rubber in the plant is first produced and thereafter broken down and utilized in its cycle of yearly development. This is not surprising when we consider the reagents heretofore employed and the drastic character of the decompositions effected by them.
