“…The role of the dopa-decarboxylase in noradrenaline synthesis was substantiated with the demonstration of the conversion of dopa and of dopamine to n9radrenaline (2)(3). In this report the effects of dopa and dopamine were studied on the spontaneous contraction, transme_mbrane potentials and content of noradrenaline in the isolated rabbit's atrium which had been depressed or abolished the spontaneous activity and depleted the content of noradrenaline by reserpine.…”

In the foregoing report Matsuo and Tachi (1) showed that though the isolated atrium of rabbit which was beating in vitro took up considerable amounts of noradrenaline added to the bath fluid, the content of noradrenaline of the restarted atrium by addition of nor adrenaline did not significantly differ from the reduced content of noradrenaline of the atrium which was ceased to beat by addition of 10 of reserpine.From the results the authors suggested that the restarting effect derived from the pharmacological action of the catecholamine and not from the biochemical binding of catecholamine to the storage site. The role of the dopa-decarboxylase in noradrenaline synthesis was substantiated with the demonstration of the conversion of dopa and of dopamine to n9radrenaline (2-3). In this report the effects of dopa and dopamine were studied on the spontaneous contraction, transme_mbrane potentials and content of noradrenaline in the isolated rabbit's atrium which had been depressed or abolished the spontaneous activity and depleted the content of noradrenaline by reserpine.

ZUSAMMENFASSUNG:1. Es wurden die Naphthalindicarbonsaure-1,4, 1,4-Dihydronaphthalindicarbonsaure-1,4 und die 2,6-Dimethyl-l,4-Dihydronaphthalindicarbonsaure-1,4 und deren Polyanhydride dargestellt ; letztere sind nicht so temperaturbestandig wie die Terephthalsaureanhydride.2. Aus 1,4-Dihydronaphthalindicarbonsaure-1,4, 1,2-Dihydronaphthalindicarbonsaure-1,2 und 2,6-Dimethyl-l,4-Dihydronaphthalindicarbonsaure-1,4 wurden ungesattigte Polyester mit Bthylenglykol hergestellt. Copolymerisationsversuche mit Styrol wurden durchgefiihrt. Nur der 1,4-Dihydronaphthalindicarbonsaure-1,4-Polyester konnte copolymerisiert werden. SUMMARY:1. The following acids and their polyanhydrides were prepared: Naphthalenedicarboxylic acid-l,4,1,4-dihydronaphthaleneylicarboxylic acid-1,4 and 2,6-dimethyl-l,4-dihydronaphthalenedicarboxylic acid-2,4; they are not so stable towards temperature, as compared with terephthalic-acid-polyanhydrides.2. Out of the 1,4-dihydronaphthalenedicarboxylic acid-1,4, 1,2-dihydronaphthalenedicarboxylic acid-l,2 and 2,6-dimethyl-l,4-dihydronaphthalenedicarboxylic acid-1,4 unsaturated polyester with ethylenglycol were prepared. Attempts were made to copolymerise these polyesters with styrene. Copolymerisation was successful only with 1,4-dihydronaphthalenedicarboxylic-acid-1,4-polyester.
