Paper electrophoresis of the soluble proteins of the central nervous tissue

Riassunto Le proteine idrosolubili estratte dal sistema nervoso di ratti sono state separate mediante elettroforesi su carta.Il quadro elettroforetico appare costantemente riproducibile nelle condizioni sperimentali impiegate.     

A starch gel electrophoretic study of the hemolymph proteins of some bermuda crustacea

Zusammenfassung Haemolymphe Proteine von 10 dekapoden Krebsen aus den Bermudas wurden mit Hilfe der «Starch-Gel»-Elektrophorese untersucht. In acht Arten erwiesen sich die zwei langsamsten Proteinkomponenten als Kupfer-positiv, in zwei Arten wurde nur eine einzige Kupfer-positive Bande ermittelt. Die Esteraseaktivität war mit den meisten Kupfer-positiven Banden verbunden, wobei 10^–4 Eserinsulfat keine Hemmung der Aktivität herbeiführte. Diese und weitere Versuche legen die Vermutung nahe, dass bei einigen Crustaceen zwei Molekülarten von Haemocyan vorkommen.

Effect of adrenalectomy on sound-induced seizure susceptibility and intensity in genetically susceptible rats

Summary Neither seizure susceptibility nor intensity was altered by sham-operation or by adrenalectomy in adult rats that are genetically susceptible to sound-induced seizures. Thus, sound-induced seizures in genetically susceptible rats are analogous to those in genetically susceptible mice to the extent that removal of the adrenal glands does not alter established seizure characteristics in either species.     

Effect of adrenalectomy on the response of rat liver polyribosomes to whole-body gamma radiation

Résumé L'adrénalectomie supprime le net déplacement, causé par l'irradiation, vers les espéces de polyribosomes plus lourdes observées chez les rats normaux irradiés. Ces résults font supposer que l'action de l'irradiation sur les polyribosomes du foie est réglée au moins en partie, par la glande surrénale.

Paper electrophoresis separation of the soluble proteins of rat muscle sarcosomes

Riassunto Viene descritta la presenza, nel succo dei sarcosomi del muscolo di ratto, di 4 componenti proteici separabili mediante elettroforesi su carta. I 4 componenti sono rappresentati nella misura di rispettivamente 26.1, 18.4, 33.2 e 22.3 per 100 delle proteine totali.     

Effect of adrenalectomy and dexamethasone treatment on the monoamine oxidase activity in the thyroid gland of the rat

Summary Adrenalectomy increased MAO activity in the thyroid gland of rats. The administration (200 g/100 g daily for 7 days) to adrenalectomized rats decreased MAO activity below levels of intact controls.     

Trypsin sensitivity of some proteins of the sea-urchin egg before and after fertilization an electrophoretic analysis

Riassunto La frazione precipitata al 50% di saturazione di solfato di Ammonio da estratti di uova vergini e fecondate diArbacia lixula presenta all'analisi elettroforetica un gruppo principale di tre componenti. Per trattamento con tripsina questo gruppo si risolve in cinque componenti nella frazione proveniente da uova vergini ed in quattro in quella proveniente da uova fecondate.     

Studies on the dye-binding fraction of soluble liver proteins from rats fed aminoazo dyes

Résumé Les auteurs ont étudié le profil électrophorétique du surnageant de foies de rats, nourris aux colorants azoïques cancérogènes. La fraction, dite protéine «h», a été isoléc et on a déterminé son poids moléculaire, sa teneur en colorant lié, en vitamines et en acides nucléiques et sa composition en acides aminés.

Differences between the soluble mitochondrial proteins in various organs of the rat

Résumé Les phérogrammes obtenus après électrophorèse en acrylamide des protéines mitochondriales solubles du rein, du foie et du cur, montrent des différences dans ces 3 organes. Le profil électrophorétique est reproductible et caractéristique pour la fraction mitochondriale de ces organes.     

Paper electrophoresis of soluble proteins of rat liver mitochondria

Riassunto Mediante elettroforesi su carta si dimostra la presenza nei lisati di mitocondri di fegato di ratto di almeno 5 componenti proteici. Le colorazioni specifiche dimostrano la presenza di 3 frazioni lipoproteiche e di altrettante glicoproteiche. I lisati dei mitocondri vennero ottenuti qer trattamento delle particelle con Triton X-100.
