TL;DR: The results obtained indicate a facilitatory role of histamine on prolactin release, which seems to be specific and not mediated by other neurotransmitters.
Abstract: Histamine injected into the 3rd ventricle of normal male rats at doses of 5–60μg (free base) caused a marked release of prolactin. Responses were prevented by the antihistamine chlorpheniramine but not by atropine, methysergide or phenoxybenzamine. It thus seems that effects of histamine on prolactin are specific and not mediated by other neurotransmitters. Plasma LH remained normal after injection of low doses but it was decreased after high doses. The results obtained indicate a facilitatory role of histamine on prolactin release.

TL;DR: In this article, the diffusion coefficients of 7Be in both α and β phases of Zr, are reported, and the temperature dependence of the diffusion coefficient in the α phase may be expressed by DBeα-Zr = 0.33 exp(−31900/RT) cm2/s.

TL;DR: The results suggest that either melatonin biosynthesis does not occur rhythmically in the organ during Antarctic summer, or melatoniniosynthesis is independent of the daily variation in light intensity.

TL;DR: In this article, a high torque specimen manipulator for use in ultra-high vacuum is described, which allows the specimen to be rotated through 360 ° and translated 1 cm along the rotation axis.

TL;DR: In this article, a strong correlation is found between the Z 2 dependence of the electronic stopping cross-sections for 4He ions of a given velocity and the Z dependence of atomic potentials at a certain radius.
Abstract: A strong correlation is shown to exist throughout the periodic table : etween the Z 2 dependence of the electronic stopping cross-sections for 4He ions of a given velocity and the Z dependence of the atomic potentials at a certain radius. An empirical formula is presented which allows the extrapolation of stopping cross-section data for any ion at a given velocity in some elements, to elements for which experimental data are not available. This study covers the energy interval 100 < E/m < 1000 keV/amu.

TL;DR: In this article, it is explicitly shown that thresholds in rapidity do not modify the critical behaviour of RFT, and a rule to determine the threshold for any diagram is given.

TL;DR: In this paper, the electric resistivity spectrum of polycrystalline Ta severely deformed at 4.2/sup 0/K, particularly on the stage showing up at approximately 275/sup 1/K.

TL;DR: In this paper, a model for high-energy amplitudes dominated by secondary reggeons based on threshold effects for the appearance of large rapidity gaps is discussed, which can be reinterpreted in terms of its J-plane singularity structure: real and complex poles and a cut.
Abstract: We discuss a model for high-energy amplitudes dominated by secondary reggeons based on threshold effects for the appearance of large rapidity gaps This model can be reinterpreted in terms of itsJ-plane singularity structure: real and complex poles and a cut In contrast to a simple Regge-pole approach, it turns out to be an appropriate scheme to handle the difficulties associated with the phenomenology of ρ and A2 exchanges In this way the present expansion can be thought of as a phenomenologically adequate perturbative treatment of reggeon field theory
