Under conditions of a few behavioral tests on rats, we examined the psychotropic activity of novel N-uronoyl derivatives of
amino acids: (i) N-(1,2:3,4-di-O-isopropylidene-α-D-galactopyranuronoyl-β-alanine (DAGU-Ala), (ii) DAGU-glycyl-D,L-glutamic
acid (DAGU-Gly-Glu), and (iii) DAGU-glycyl-glycine (DAGU-Gly-Gly) injected i.p. in a 50 mg/kg dose. In an open-field test,
DAGU-Gly-Glu and DAGU-GLy-Gly showed antistress properties (they decreased the intensity of locomotion, decreased the number
of defecation acts, and intensified the research activity), while DAGU-Ala possessed a psychostimulating effect (intensification
of locomotor and research activity and an increase in the number of defecations). In the “black-and-white chamber” test, only
DAGU-Gly-Gly exerted an anxiolytic effect; it somewhat increased the frequency and duration of emergings of animals from the
dark section and duration of visits to the illuminated section of the chamber. DAGU-GLy-Glu manifested antidepressant properties;
it increased the time of active swimming of the animal in the Porsolt test and decreased the duration of passive “hanging”
of rats in the “suspension by the tail” test.

A relationship between the FV blood group phenotype and 4 out of 45 haematological and blood chemical parameters — red cell number, mean corpuscular volume (MCV), mean corpuscular haemoglobin concentration (MCHC), and serum iron — has been demonstrated in young bulls of three Swiss cattle breeds. There was also a relationship between haemoglobin type and 7 out of 45 haematological and blood chemical parameters (haemoglobin concentration, red cell number, MCV, MCHC and red cell concentrations of K+ and Na+ and their sum). In addition to expanding the species in which there is an effect of haemoglobin phenotype on MCV to include cattle, these data also demonstrate a significant correlation between their FV phenotype and MCV. 相似文献

Several Markov chain models (up to fourth order) have been fitted to the sequences of the seven DNAs presented in Fuchs et al. (1980). Two methods for determining the order of Markov chain are applied to the data. The two methods lead to different conclusions and we dicuss these discrepancies. When the distribution of the nucleotides in a DNA sequence is investigated, it is suggested that the study on the order of the Markov model should be supplemented with additional analysis. 相似文献

In this paper we are concerned with test procedures for umbrella alternatives in the k-sample location problem. Distribution-free tests are considered for both cases where the peak of the umbrella is known or unknown. Comparative results of a Monte Carlo power study are presented. 相似文献

This paper is concerned with testing for umbrella alternatives in a k-sample location problem when the underlying populations have possibly different shapes. Following CHEN and WOLFE (1990b), rank-based modifications of the HETTMANSPERGER-NORTON (1987) tests are considered for both the settings where the peak of the umbrella is known and where it is unknown. The proposed procedures are exactly distribution-free when the continuous populations are identical with any shape. Moreover, the modified test for peak-known umbrella alternatives remains asymptotically distribution-free when the continuous populations are assumed to be symmetric, even if they differ in shapes. Comparative results of a Monte Carlo study are presented. 相似文献
