[Clinical, radiological and histological results after vital treatment of exposed pulps].

The authors present the clinical and radiological results of their long-time controls of 210 permanent teeth after direct capping of the exposed pulp and describe some histological findings. The over-all evaluation of the results permits to conclude that the method of direct pulp capping is more successful only if the indication is established discriminately. The patient's age is of no or minor importance to the choice of treatment.

[Occurrence and behavior of fibrin fibrinogen degradation products in concentrates of factor VIII, cryoprecipitate and dextran precipitate during long-term preservation].

In deep-frozen and lyophilized cryoprecipitates and dextran precipitates it was analyzed by the TRCHII and the SCT, whether these factor VIII concentrates contain fibrinogen fission products effecting as inhibitors of the coagulation of blood and how they act during storage for 200 days. Simultaneously the parameters total protein, fibrinogen, fibrin monomers, plasminogen and factor VIII activity were always determined. In all preparations being tested fibrinogen fission products could be detected. Lyophilized cryoprecipitates showed the highest average values with 7.97 microgram/ml (TRCHII) resp. 18.31 microgram/ml (SCT). They were followed by deep-frozen cryoprecipitates with 6.93 microgram/ml (TRCHII) resp. 7.54 microgram/ml (SCT). Deep-frozen dextran precipitates free of heparin contained the fewest fission products (TRCHII: 0.36 microgram/ml; SCT: 3.13 microgram/ml). At the beginning of the storage only few fission products were found in all groups of preparates. A predominantly clear rise with forming a peak after about 115 to 145 days and a drop following happened with extended storage period. This course of storage of the quantities of fission products shows that the fibrinogen fission products arise during storage.

[Passive electrical investigations on erythrocytes in dependence of age donars (author's transl)].

It was shown by passive electrical investigations, that the behavior of electrical relaxations of red cells depends on age. With increasing age of the human the relaxation time as well as man the exchange effect stability be increased. This results are due to the increasing of the volume and the contents of haemoglobin of the erythrocytes, and may be due to the changing of the charge of the membrane.

[Comparison of short and protracted streptokinase therapy in acute myocardial infarction].

In numerous controlled studies the effectivity of the streptokinase therapy of the acute myocardial infarction is proved by a significant decrease of the early lethality. The main difference of the therapeutic methods lies in the duration of the application of streptokinase. Of the number of patients of an intensive therapy ward for internal diseases comparisons of the results of therapy of one year with short-term lysis (3 hours) are contrasted with one year with protracted lysis therapy (24-72 hours). The findings demonstrated plead for the fact that by means of the short-time lysis may also be achieved good, perhaps even better results. Issuing from the therapeutic mechanisms of the lysis therapy in the sense of a prevention of the formation of thrombi in disturbed microcirculation by the achieved hyperplasminaemia the short-term lysis is to be regarded as optimum introduction of an anticoagulant long-term therapy.
