Abstract

Thalamic neurons projecting to both the head of the caudate nucleus and the premotor cortex in the cat were studied by the retrograde fluorescent double labeling technique. After injections of Evans blue into the caudate nucleus, and diamidino-phenylindol into the premotor cortex, a small number of double labeled neurons appeared in the ventral anterior, ventral lateral, anteromedial, rhomboid, central dorsal, central lateral, central medial, paracentral and parafascicular nuclei, in addition to numerous single-labeled neurons. This indicates that some neurons in the thalamic nuclei send bifurcating axons to both the head of the caudate nucleus and the premotor cortex. The caudatal projections of these thalamic neurons are organized in a topical manner.

Abstract

Catecholamines were measured in the amniotic fluid and in the first voided newborn urine obtained from appropriate-for-date infants of term deliveries. Catecholamine values in the amniotic fluid and urine were nearly equal when expressed in terms of creatinine. Significant positive correlations were observed between the amniotic fluid and urine of norepinephrine and epinephrine. In normal cases (n = 32) that underwent uneventful vaginal delivery, the 95% confidence limits for norepinephrine and epinephrine in the amniotic fluid were 1.53 to 2.33 ng/ml and 0.16 to 0.30 ng/ml, respectively. In cases of moderate stress (n = 12), only norepinephrine showed significantly higher values than the normal cases, while in cases of severe stress (n = 12), norepinephrine became more significantly high, and epinephrine was found to be elevated significantly. A significant difference was noted in the incidence of fetal stress between the infants with more than and those with less than 2.30 ng/ml of norepinephrine, the upper limits of the normal 95% confidence limits. However, for epinephrine such a significant difference was not noted. It was concluded that amniotic fluid catecholamines are of fetal origin and reflect fetal sympathoadrenal activity directly, even during labor, and that their level may be a good indicator of fetal condition and stress.

Abstract

Age-associated changes in methionine-enkephalin (ENK) and thyrotropin releasing hormone (TRH) concentrations, and their receptors were examined in discrete regions of the rat brain. The ENK and TRH concentrations in aged rats were nearly identical to those in young adult rats, except for a slightly lower TRH value in the hypothalamus of the aged rats. On the other hand, the ENK and TRH receptor levels in the cerebral cortex of aged rats was markedly lower than that of young adults rats. The results suggest that determinations of both neuropeptide and receptor levels are indispensable for evaluation of peptide-mediated neural systems in the central nervous system.

Abstract

Vectorcardiograms were recorded with the Frank lead system using electrodes positioned at the level of the 5 th intercostal space with the subject in the supine position. Deep inspiration produced the following significant changes compared with deep expiration: (1) the maximum leftward forces of the P, QRS, and T vectors decreased, whereas the maximum anterior and posterior forces of the QRS and T vectors increased; (2) the maximum spatial QRS vector decreased in magnitude; (3) the maximum spatial P, QRS, and T vectors shifted vertically, posteriorly and vertically, and anteriorly, respectively; and (4) the spatial QRS-T angle increased remarkably. The spatial instantaneous QRS vectors were analyzed at 5 msec intervals in 35 of the 61 subjects. With inspiration, the 35- through 50-msec vectors shifted posteriorly with markedly reduced leftward forces and increased posterior forces. It was suggested that the respiration-related vectorcardiographic changes reflected cardiac anatomic positional change, distortion of lead-field potential by lung gases, and other mechanisms. Since the respiratory effect is potentially important for vectorcardiographic interpretation, vectorcardiograms should be recorded under identical respiratory status.

Abstract

Der Einfluβ des rohen und gekochten Eigelbs, sowie des atherischen und alkoholischen Eigelbextraktes auf die Gallen- und Gallensaureausscheidung des Fistelhundes wurde untersucht und folgende Ergebnisse erhalten. 1. Durch Futterung mit rohem und gekochtem Eigelb werden die Gallen- und Gallensaureausscheidung stark vermehrt. Diese Vermehrung bei Zufuhr gekochten Eigelbs dauert mehrere Tage lang als die bei Zufuhr von rohem, wahrend die Zufuhr von Eierklar keinen Einfluβ darauf ausubt. 2. Diese die Gallen- und Gallensaureausscheidung vermehrenden Bestandteile gehen in Ather und zum Teil auch in Alkohol uber, indem der atherische und alkoholische Extrakt bzw. der erstere die Gallen- und Gallensaureausscheidung vermehrt.

Abstract

1. Der Zuckergehalt im Blut des 1 oder 4 Tage hungernden Kaninchens wird durch Futterung mit Nukleinsaure fast gar nicht beeinfluβt, wahrend die hypoglykaemische Wirkung der Cholsaure anscheinend dadurch verstarkt wird. 2. Die durch Zufuhr von Traubenzucker erzeugte experimentelle Hyperglykaemie wird durch parenterale Zufuhr von Nukleinsaure fast gar nicht beeinfluβt.

Abstract

1. Die Neoglykogenie der Leber wird sowohl durch Zufuhr von Eierklar als auch durch solche von Edestin in gleichem Grad gesteigert. 2. Diese durch Eierklar gesteigerte Neoglykogenie wird durch gleichzeitige Zufuhr von Cholsaure weiter verstarkt, wahrend sie durch gleichzeitige Zufuhr von Cholesterin entweder nicht beeinfluβt oder vielmehr herabgesetzt wird. 3. Die durch Edestin gesteigerte Neoglykogenie wird durch gleichzeitige Zufuhr von Cholsaure etwas verstarkt oder kaum beeinfluβt.

Abstract

1. The gaseous metabolism of normal healthy guinea pigs was increased by the administration of lotus rhizome juice or platan leaves juice. 2. The goseous metabolism of normal guinea pigs was slightly increased by the administration of testis extract, and more markedly so by the administration of lotus rhizome juice together with it. 3. The gaseous metabolism of guinea pigs fed with the basal diet free from vitamin C decreased with the diminution of their body weight, and it again increased transitorily by the administration of lotus rhizome juice. 4. The gaseous metabolism of the castrated male guinea pigs was increased by the hypodermal injection of "Spermatin".

Abstract

Der Befund bei einem Exemplar von Racophorus Schlegelii, das die Arcizonie zeigte, fuhrt mich uber die Entwicklungsgeschichte des Schultergurtels aller anuren Amphibien zu folgender Uberlegung : Der primare Ausgangszustand des Schultergurtels bei der anuren Amphibien ist die Laxizonie, von dieser leitet sich die Arcizonie ab, dann ergibt sich endlich die Firmizonie aus der Arcizonie. Daher stellt die Firmizonie den am hochsten entwickelten Typus des Schultergurtels dar. In andern Worten : die Arcizonie kommt bei Racophorus Schlegelii nicht vor, aber Phylogenetisch liegt doch ein arcizonaler Zustand vor, wie bei diesem Fall von Racophorus Schlegelii, der die Arcizonie aufweist, die einen Rest des phylogenetischen Gebildes darstellt und gelegentlich eben doch auftritt.

Abstract

1) The gaseous metabolism of guinea pigs (male and female) decreases to a certain extent after the removal of sexual glands, but it increases temporarily through the administration of the extract (of testis or ovary), up to the normal value as before the operation. 2) The testis extract has a little influence on increasing the gaseous metabolism of the ovariectomised guinea pigs and it is also temporary. 3) The oxidizable substances cause the gaseous metabolism of ovariectomised guinea pigs to increase markedly. 4) The gaseous metabolism of the castrated male is increased under the administration of the oxidizable substance of certain plant juices and the ratio of increase is proportional to the quantity of the oxidizable substance given, and the more, if the testis extract be added together. 5) The gaseous metabolism of the castrated animals fed with the basal diet free from vitamin C tends to diminish again. This diminished gaseous metabolism is only restored to the former level or more by the administration of vitamin C.

Abstract

1. Beim Kaninchenembryo zeigen sich nur die unreifen, starker geladenen Erythrocyten durch unsere Impragnationsmethode geschwarzt, wahrend die reifen, schwacher negativ geladenen sich durch diese nicht impragnieren lassen. 2. Bei dem Reifen der Erythrocyten geht die Polychromasie derselben mit der Argentophilie parallel zuruck.

Abstract

1. Es wurde der Kalzium- und Magnesiumgehalt von verschiedenen Organen und Geweben des Kaninchens untersucht und es wurde gefunden, daβ der Kalk in der Lunge am reichlichsten, dann der Reihenfolge nach in Knochen, Niere, Hirn, Leber, Herz und Muskel weniger enthalten ist, wahrend von Magnesium die reichste Menge im Knochen dann der Reihenfolge nach in Muskel, Niere, Leber, Herz und Lunge eine geringere Menge vorhanden ist. 2. Der Kalkgehalt der Organe und Gewebe wird durch Zufuhr von Cholsaure bei der Leber und Niere am starksten gesteigert, dann kommen der Reihenfolge nach Muskel, Herz, Hirn und Knochen. In der Lunge wird er dagegen durch sie etwas herabgesetzt. 3. Der Magnesiumgehalt in den Organen und Geweben wird durch Zufuhr von Cholsaure im allgemeinen etwas vermehrt, im Hirn und im Herzen dagegen etwas herabgesetzt.
