    Notes: Abstract: Vasopressin receptors have been reported in the endothelium of brain capillaries. The function of these receptors is not known. To test the prediction that vasopressin receptors in brain capillary endothelium affect amino acid transport across the blood-brain barrier and to assess the role of vasopressin transport across the cerebral vascular endothelium, we measured (a) the endothelial permeability to the large neutral amino acid leucine in the absence and presence of arginine vasopressin (AVP) and (b) the permeability of the blood-brain barrier to AVP relative to mannitol. In brain regions protected by the blood-brain barrier, after circulation for 20 s, coinjection of leucine and AVP intravenously led to a decrease of leucine transport unrelated to changes of blood flow. The decrease was most pronounced in hippocampus (42%) and least pronounced in olfactory bulb and colliculi (17 and 19%, respectively). In the latter regions, the endothelial permeability to AVP did not significantly exceed that of mannitol. In hippocampus and in regions with no blood-brain barrier (pituitary and pineal glands), AVP retention in excess of mannitol retention was blocked by unlabeled AVP. The findings do not contradict the hypothesis of a role for AVP in the regulation of large neutral amino acid transfer into brain tissue.

    Notes: Abstract: After intracarotid injection of [3H]β-casomorphin-5 (βCM5) in rats, the accumulation of radioactivity was determined in 18 brain regions and the anterior pituitary. The relative accumulation in all regions significantly exceeded that of [3H]inulin by a factor of 2.5, indicating a low but measurable brain uptake of the peptide. In blood-brain barrier-free areas, the accumulation of radioactivity was 15-fold higher than in blood-brain barrierprotected areas. The relative accumulation was not dependent on the total βCM5 concentration in the range of 0.3–1.1μM, and was not depressed by 400μM L-tyrosine. We conclude that βCM5, like other peptides, is accumulated in the blood-brain barrier-free areas to a relatively high but differing degree, whereas in the areas with a tight endothelium the accumulation is relatively low and nearly uniform. A binding to endothelial cells may contribute to the low accumulation of βCM5, especially in blood-brain barrier-protected areas.

    Notes: Summary The glycoprotein of Reissner's fibre is able to bind norepinephrine, epinephrine and serotonin. Bound amines can be demonstrated at the RF, even after washing with artificial cerebrospinal fluid for some, hours. It is discussed whether it is a function of the RF to remove substances, for instance biogenic amines, from the cerebrospinal fluid.

    Notes: [Auszug] Histoautoradiographic investigations after the injection of 35S-cystine (1-2 4*8 jxc./body weight, partly repeated) have shown that 35S-incorporation of sulphur-35 into the SCO and Reissner's fibre in the carp (Cyprinus carpio L.) is greater than in most other organs (Figs. 1 and 2).

    Description / Table of Contents: Zusammenfassung 1. Mit der Untersuchung wurde das Verhalten des vom Subcommissuralorgan gebildeten Reissnerschen Fadens 1–24 Std nach Injektion von3H-Tyrosin,3H-Alanin und35S-Cystin in den Seitenventrikel von Katzen geprüft. Die Verabreichung der Aminosäuren erfolgte über eingeheilte Kanülen. 2. Die Art der Tyrosin-Markierung des RF läßt sich weder als Bausteinmarkierung, d.h. als im SCO stattfindender Einbau des Tyrosins in das Sekret, noch als postmortaler Artefakt, d.h. als Anlagerung von Tyrosin an den RF durch Formalin-fixierung erklären. Vielmehr muß angenommen werden, daß es in vivo zu einer chemischen Bindung zwischen Tyrosin und dem Glykoproteid des RF kommen kann. Die notwendigen Ankergruppen könnten zum Teil von der im RF enthaltenen N-Acetyl-Neuraminsäure geliefert werden.
    Notes: Summary 1. The fibre of Reissner (RF) a secretion of the subcommissural organ (SCO) was proved 1 to 24 hours after injections of3H-alanine,3H-tyrosine and35S-cystine into the lateral ventricle of cats. The amino acids were given by a cannula implanted 14 days before. 2. The kind of the tyrosine-labelling of Reissner's fibre cannot be explained as labelling of elements, i.e. as an insertion of the tyrosine into the secretion taking place in the SCO, nor as a postmortal artefact, i.e. as attachment of tyrosine to the RF by formaline-fixation. But it must be accepted, that there exists the possibility of a chemical binding between tyrosine and the glycoproteid of RF in vivo. The necessary anchor-groups might partly be delivered by the N-acetylneuraminic acid of the RF.
