Die Wirkung von synthetischen Antihistaminkörpern auf die Senfölchemosis am Kaninchenauge

Summary Intravenous or subcutaneous administration of pyribenzamine and other antihistaminics is able to decrease, and to delay the appearance of chemosis produced by mustard oils in the eye of the rabbit. Simultaneously occurring vascular reactions, on the other hand, are but slightly affected by antihistaminics. Intravenous or subcutaneous administration of rutin has no clear-cut effect on chemosis; it is however able to inhibit the vascular reaction.     

Der Einfluß der Nebenniere auf die Kreislaufwirkung des Adrenalins

Summary Traces of nor-adrenaline restore the vascular action of adrenaline altered in epinephrectomized dogs to the reaction of the normal animal. Therefore it is claimed that the adrenals discharge one or several substances into the blood stream, which are necessary for the usual peripheral vascular action of adrenaline. Further investigations are in progress.     

Timed bromocriptine administration reduces body fat stores in obese subjects and hyperglycemia in type II diabetics.

Obese postmenopausal female volunteers were given timed daily oral dosages of bromocriptine, and tested for reduction of body fat stores. This dopamine agonist has been shown to reset circadian rhythms that are altered in obese animals and to reduce body fat levels in several animal models. The participants were instructed not to alter their existing exercise and eating behavior during treatment. Skinfold measurements were taken on 33 subjects as indices of body fat. The measurements (e.g., suprailiac) were reduced after six weeks by about 25%, which represents a reduction of 11.7% of the total body fat. These dramatic decreases in body fat, which are equivalent to that produced by severe caloric restriction, were accompanied by more modest reductions of body weight (2.5%), indicating a possible conservation of protein that is usually lost as a consequence of such caloric restriction. The effects of bromocriptine treatment on body fat and hyperglycemia were also examined in non-insulin dependent diabetics being treated with oral hypoglycemics (7 subjects) or insulin (7 subjects). Total body fat was reduced by 10.7% and 5.1% in diabetics on oral hypoglycemics and insulin, respectively, without any significant reductions in body weight. Hyperglycemia was reduced in most of the 15 diabetic subjects treated leading to euglycemia and even cessation of hypoglycemic drugs in 3 of the 7 subjects during 4-8 weeks of bromocriptine treatment. These findings support the hypothesis that obesity and type II diabetes may be treated effectively with bromocriptine when administered at the proper times and dosages.

An extragalactic supernebula confined by gravity

Little is known about the origins of globular clusters, which contain hundreds of thousands of stars in a volume only a few light years across. Radiation pressure and winds from luminous young stars should disperse the star-forming gas and disrupt the formation of the cluster. Globular clusters in our Galaxy cannot provide answers; they are billions of years old. Here we report the measurement of infrared hydrogen recombination lines from a young, forming super star cluster in the dwarf galaxy NGC5253. The lines arise in gas heated by a cluster of about one million stars, including 4,000-6,000 massive, hot 'O' stars. It is so young that it is still enshrouded in gas and dust, hidden from optical view. The gases within the cluster seem bound by gravity, which may explain why the windy and luminous O stars have not yet blown away those gases. Young clusters in 'starbursting' galaxies in the local and distant Universe may also be gravitationally confined and cloaked from view.     

Mechanismus der Reaktion von Invertseifen mit isolierten Zellen

Summary Reaction equilibria were established between an invert soap on the one side and carbon, lecithin, erythrocytes and yeast cells on the other side. From the parallelism of the invert soap-lecithin and the invert soap-erythrocytes curves a specific reaction of the invert soap with the lipoids of the erythrocytes may be concluded, whereas the invert soap-yeast cells curves yield a pure adsorption isotherm corresponding to the invert soap-carbon curve.     

Ähnlichkeit und Unterschied Leukozytenemigrationsfördernder Wirkung gram-positiver und gram-negativer Bakterien

Summary Live gram-positive and gram-negative bacteria cause circular and chemotactic eccentric promotion of leucocyte emigration in a similar manner. In the case of gramnegative bacteria this effect corresponds to that of their polysaccharides, whereas in the case of gram-positive bacteria the polysaccharides are inactive.Thus, although gram-positive and gram-negative bacteria both have a similar effect on leucocyte emigration, the underlying mechanism of action is different.     

Produktion von leukozytenemigrationsfördernden Stoffen durch grampositive Keimein vitro

Summary Streptococcus pyogenes haemolyticus grown in glucose broth is capable of producing or liberating a heat-stable factor of high molecular weight which stimulates the emigration of leucocytesin vitro, only if certain animal organs are present.
