    Description / Table of Contents: Zusammenfassung Die Sekretion von retinolbindendem Protein (RBP) ins Blut von Ziegen wurde nach unterschiedlicher Verabreichung von Vitamin A (Retinylacetat), Β-Carotin und einer Mischung von pflanzlichen Carotinoiden untersucht. Die Zufuhr dieser Verbindungen — entweder in einer einzelnen hohen Dosis oder in der gleichen Menge gleichmäßig auf 4 Tagesdosen verteilt — führte zu einem deutlichen Anstieg der RBP-Sekretion. Diese Sekretion erfolgte in zwei Phasen, von denen eine früh und eine später einsetzte.
    Notes: Summary Studies were conducted on the secretion of retinol-binding protein (RBP) in blood of goats given different treatments of preformed vitamin A, Β-carotene and plant carotenoids. Administration of these sources either in a single massive dose or massive dose split into four equal doses, markedly increased the secretion of RBP in blood. The secretion of RBP in blood occurred at least in two phases, one at early periods and the other at later periods.

    Description / Table of Contents: Zusammenfassung Der Einfluß einer Beschränkung der Vitamin-A-Zufuhr für das Muttertier auf die biochemische Entwicklung der Lunge des Jungtieres wurde bei Ratten untersucht. Der Vitamin-A-Status der Muttertiere wurde durch niedrige, mittlere und adäquate Gaben von Vitamin A während Trächtigkeit und Säugezeit variiert (6, 40 und 100 μg Retinol/Tag/kg Körpergewicht). Die Ergebnisse zeigen, daß die Beschränkung der Vitamin-A-Zufuhr für das Muttertier das Wachstum und die Entwicklung der Lunge in bezug auf Gewicht, DNA- und Proteingehalt und -biosynthese aus markierten Vorstufen, RNA-Gehalt, Zellgröße und Zellzahl beeinflussen.
    Notes: Summary The effect of maternal vitamin A restriction on the biochemical development of the lung in rats has been studied. The vitamin A status of dams has been varied by supplying low, medium and adequate amounts of vitamin A (6, 40 and 100 μg retinol/day/kg body weight, respectively) during pregnancy and suckling. The results demonstrate that the restricted supply of vitamin A to the mother affected the growth and development of the lung in parameters of tissue weight, DNA and protein levels and their biosynthesis from respective labelled precursors, RNA contents, cell number and cell size.

    Production, morphology, and cytogenetic analysis of Elymus caninus (Agropyron caninum) x Triticum aestivum F1 hybrids and backcross-1 derivatives (1986)

    Notes: Summary Intergeneric hybrids were produced between common wheat, Triticum aestivum (2n=6x=42, AABBDD) and wheatgrass, Etymus caninus (Agropyron caninum) (2n=4x=28, SSHH) — the first successful report of this cross. Reciprocal crosses and genotypes differed for percent seed set, seed development and F1 hybrid plant production. With E. caninus as the pollen parent, there was no hybrid seed set. In the reciprocal cross, seed set was 23.1–25.4% depending upon wheat genotype used. Hybrid plants were produced only by rescuing embryos 12–13 days post pollination with cv ‘Chinese Spring’ as the wheat parent. Kinetin in the medium facilitated embryo germination but inhibited root development and seedling growth. The hybrids were vigorous, self sterile, and intermediate between parents. These had expected chromosome number (2n=5x=35, ABDSH), very little chromosome pairing (0.51 II, 0.04 III) and some secondary associations. The hybrids were successfully backcrossed with wheat. Chromosome number in the BC1 derivatives varied 54–58 with 56 as the modal class. The BC1 derivatives showed unusually high number of rod bivalents or reduced pairing of wheat homologues. These were sterile and BC2 seed was produced using wheat pollen.
