    Description / Table of Contents: Zusammenfassung Es wurde der Einfluß folgender Chelatbildner: 1. Diäthylentriaminpentaessigsäure (DTPA), 2. 2,2′-Bis[di(carboxymethyl)amino]diäthyläther (BADÄ), 3. 2-(β-Aminoäthoxy)cyclohexylamintetraessigsäure (ACATA) und 4. Desferrioxamin B (DF) auf die Fe-Ausscheidung mit dem Urin von Ratten geprüft. Sowohl bei Kontrolltieren als auch bei experimentell induzierter Fe-Speicherkrankheit nimmt die Wirksamkeit in der Reihenfolge DTPA 〈 BADÄ ≃ DF 〈 ACATA zu. Die akute LD 50 bei der Maus beträgt 2,4 mM DF·kg−1 und 12,7 mM ACATA·kg−1.
    Notes: Summary The influence of 1. diethylenetriaminepentaacetic acid (DTPA), 2. 2,2′-bis-[di(carboxymethyl)-amino]diethyl ether (BADE), 3. 2-(β-aminoethoxy)-cyclohexylaminetetraacetic acid (ACATA), and 4. desferrioxamine B (DF) on the urinary iron excretion was studied in rats. In controls as well as in animals with experimental hemochromatosis the effectivity increases in the following order: DTPA 〈 BADE ≃ DF 〈 ACATA. The acute LD50 of DF is 2.4 mM×kg−1 and of ACATA 12.7 mM×kg−1 in mice.

    Notes: Summary Diencephalic and mesencephalic lesions in albino rats elicited a disturbance of the vaginal oestrous cycle characterized by “pseudopregnancy-like” prolongation of dioestrus; occasionally decidual responses could be elicited by uterine traumatization. Oestrogen administration on the day before traumatization failed to enhance significantly the frequency of decidual responses in rats with diencephalic lesions, but succeeded in doing so in rats with mesencephalic lesions. It is assumed that the lesions destroy partially the mesencephalo-hypothalamic afferent system containing nerve fibres stimulating the hypothalamic cells producing the luteotrophin (prolactin) inhibiting factor.

    Notes: Summary Spreading depression elicited in the thalamus of albino rats anesthetized with Dial by microinjection of 0.2–1.0 μl 25% KCl is accompanied by a maximal pupillary dilatation of the paralytic type. The mydriasis starts immediately after KCl application, culminates about 90 sec later and then slowly subsides with a half time of about 5 min. Although with lateralized KCl application thalamic spreading depression reaches the ipsilateral lateral geniculate body approximately 1 min earlier than the contralateral one, the pupillary reactions are strictly synchronous in both eyes. Participation of the sympathetic fibres was ruled out by the observation that thalamic spreading depression evokes the same mydriasis in the “encéphale isolé” rats. Cortical spreading depression, on the contrary, elicits only slight and shortlasting mydriasis. Comparison of the spatial march of spreading depression through the thalamus with the time course of the pupillary reaction indicates that the maximum mydriasis is probably caused by direct invasion of the Edinger-Westphal nucleus by the spreading depression process.
