[Development of the internal ear in albino rat embryos subjected to transverse acceleration at + 3 G. Note 3: First observations on the ultrastructural picture of the labyrinth. 1st ultrastructural studies of the labyrinth].

Marked body size reduction (minus 50.5%), and delayed head and body skeletal development were noted in albino rat embryos following exposure of the mother to +/- 3 G acceleration for 3 hr/day between the 10th and 19th day of pregnancy. In addition, electron microscope examination of the inner ear showed signs of greater functional activity of the labyrinth, unaccompanied by reduction of development.

[Analysis of the hypolipemic, hypocholesteremic and platelet anti-aggregating effects of tibric acid].

Tibric acid shows interesting hypocholesteremic and hypolipemic activity greater than that of clofibrate. In addition high concentrations of tibric acid affect platelet aggregation. Tibric acid does not show choleretic activity and does not affect liver function.

[Experimental analysis of the interactions between heparin and a duodenal heparinoid].

It is shown that positive synergism exists between the clarifying, hypocholesterolaemising, hypolipidaemising and fibrinolytic effects of heparin sodium and a duodenal heparinoid. The results of pharmacokinetic and chemicophysical investigations are also presented.
