Studies on intra-arterial cushions. III. The cushions at the origin of the rat carotid body artery (CBA).

The orifice of the rat carotid body artery is surrounded by intra-cranial cushions which form a boat-like structure. The cushions are covered by normally looking endothelium, ramified smooth muscle cells are seen in its stroma. The internal elastic lamella remifies where the cushions originate, and delicate elastic fibres extend into the cushions. Axon profiles are confined to the medioadventitial border. They were never seen to penetrate into the tunica media or even to reach the cushions. It is suggested that the cushions are passively flattened during pulsatile dilatation of the external carotid artery.

[Doubling of the arteria testicularis sinistra with variations of origin and course--an embryological consideration (author's transl)].

During dissection of a human body anomalies in the origin and the course of the testicular artery have been observed. Besides a left testicular artery arching over the left renal vein there existed an additional testicular artery on the same side originating from the distal part of the left renal artery. The development of those anomalies is discussed under embryological aspects.

Characterization of synchronized cultures of Bumilleriopsis filiformis. Changes in cytochrome-f photooxidation and fluorescence induction kinetics.

Activity of the photosynthetic apparatus of synchronized cultures was studied with the xanthophycean alga Bumilleriopsis filiformis, following the kinetics of fluorescence induction and photooxidation of cytochrome f (= cytochrome c-553) of intact cells. During the beginning of the cell-division phase, minimum cellular photosynthetic activity is observed and a maximum after its completion, which is accompanied by corresponding changes in Hill reaction activity and re-reduction of cytochrome f by photosystem II light. At minimum activity, the level of steady state fluorescence was higher than at the maximum. This is due, at least in part, to the diminished electron flow between the two photosystems seemingly caused by decreased photosystem I activity. This explanation was suported by the kinetics of cytochrome-f photooxidation. Thus, electron transport activity of both photosystems appears to vary during the cell cycle.
