    Studies on the regulation of the neutrophil chemotactic response using a rapid and reliable method for measuring random migration and chemotaxis of neutrophil granulocytes (1976)

    Notes: Abstracts An economic and sensitive test system for measuring random and directional migration of human neutrophils is described. The technique, based on a modified Boyden chamber equipped with a two-filter system, permits a substantial reduction of both incubation time and sample volume. The influence of various technical factors such as the neutrophil concentration in the cell suspension, the incubation time of the chambers, the test concentration of activated plasma or serum, the presence of heparin, and the procedure for separating neutrophils from human peripheral blood, was investigated. Standardized procedures for measuring and reporting neutrophil chemotaxis are proposed. The method has been used to study the significance of factors regulating neutrophil migration such as cytotaxin inactivators and neutrophil immobilizing factors (NIF). Activity of cytotaxin inactivators as assessed in undiluted serum or plasma at pH 7.4, 6.0 or 4.0 was very low. In contrast, potent neutrophil immobilizing activity was found in human serum or diluted plasma. These factors which inhibit migration were accordingly termed neutrophil immobilizing factors of plasma (NIF-P) and neutrophil immobilizing factor of serum (NIF-S). These factors are heat-stable, non-dialysable and of high molecular weight.

    Interaction of benzodiazepines with neuroleptics at central dopamine neurons (1976)

    Notes: Summary Several benzodiazepines (chlordiazepoxide, clonazepam, diazepam and flunitrazepam) markedly counteracted the elevation of the homovanillic acid (HVA) content of the rat brain induced by neuroleptics (haloperidol, pimozide, chlorpromazine, and clozapine). A similar effect was obtained with the inhibitor of GABA transaminase, aminooxyacetic acid (AOAA). The interaction of benzodiazepines with the neuroleptic-induced HVA increase was similar in the striatum and in the limbic forebrain, and was antagonized by the GABA receptor-blocking agent, picrotoxin. Both the benzodiazepines used and AOAA potentiated the cataleptic effect of the four neuroleptics. It is concluded that benzodiazepines, by intensifying GABA-ergic transmission, enhance the ongoing inhibition of mesencephalic dopamine neurons exerted by the striatonigral GABA system. As a consequence, the feedback activation of dopamine neurons induced by the neuroleptic blockade of dopamine receptors in the striatum and the limbic system is attenuated. This results in a reduction of the neuroleptic-induced increase of HVA and in the potentiation of the cataleptic effect of neuroleptics.

    The interpretations of ultraviolet observations of comets (1976)
    Springer
    Space science reviews 18 (1976), S. 641-682

    Notes: Summary Ultraviolet observations of comets from above the Earth's atmosphere have provided excellent new results and improved older ground based observations (OH) by an order of magnitude. Satellites are especially suitable because long integration times and observations during extended time intervals are possible. The existing cometary Lα observations have confirmed the relatively high overall gas production rates on the order of 1030 molecule s−1. The results strongly support the concept of an icy conglomerate solid cometary nucleus. Additional observations of hydroxyl and oxygen favor water to be one of the most abundant molecules in comets. The observations are in agreement with the predominent role of water in the evaporation process of the nuclear ices but are not proof in themselves. Water did not outnumber other consitutents by orders of magnitude in comets Bennett and Kohoutek. At least in these comets, carbon-containing molecules were possibly as numerous as water. Determination of the carbon scale length is necessary for a more quantitative statement. A hydrogen velocity of 7–9 km s−1 was observed in comet Bennett as well as in comet Kohoutek for a variety of heliocentric distances and varying production rates. Determinations of the outflow velocity from Lα isophotes agree with line profile observations of Lα and Hα. Hydroxyl may constitute the main source for the hydrogen atoms with v H ∼- 8 km s−1. The decay process, however, leading to this particular velocity is not yet known. Possibly a large portion of the OH radicals do not decay into hydrogen atoms or at least not into slow ones. If the high velocity component of 20 km s−1 or more comprises a larger amount (up to 50%), most of the quoted hydrogen production rates must be revised upward. The intrinsic cometary brightness is only a very crude indicator of a comet's actual gas production rate as shown by comparison of comets Bennett and TSK. Comets can be successfully used as (extra ecliptic) space probes to measure interplanetary quantities, e.g., the curvature of the extended hydrogen clouds can be used for the absolute determination of the solar emission independent of instrumental calibration. Generally time dependent hydrogen density models must be used for the interpretation. The strength of the ultraviolet Lα emission favors its measurement as a standard procedure for the observation of comets (possibly together with OH (3090 Å)). These observations provide the most accurate results on the total cometary gas production rate and its variation with heliocentric distance.
