[Modification of hemorheologic parameters by beta-receptor blockers with special reference to propranolol and talinolol].

There are no systematic and complex investigations regarding the hemorheologic action of the betablockers propranolol and talinolol. The results on the other ones are contradictory. On the basis of a critical survey of the literature, in-vitro-experiments and studies in animals (rats) and humans may conclude that there are no remarkable deteriorations of rheological parameters in the therapeutic dose range.

[Epidemiology of hormone dependent malignant tumors--ovulation inhibitors and liver tumors].

Since the first descriptions of liver tumours associated with the intake of steroid contraceptives, the literature has presented an increasing number of case reports as well as epidemiological studies on the relationship between benign liver tumours and the utilization of these drugs. We report 11 benign cases and one malignant case of liver tumours in connection with the intake of these steroid preparations.
