The official methods of control of vaccines against sheep enterotoxemia are indirect in two ways : on the one hand they are carried out on animals for which the vaccine is not intended, and on the other hand they test only an immunological serum reaction. Another method consisting of direct testing by intravenous injection of toxin has been carried out on mice previously vaccinated with different doses. It has been shown that it is possible to obtain a certain level of protection giving a good dose-effect relation. However, immunity provided by this direct method is weak although the vaccine utilized is considered very efficacious with regard to the official norms of the direct test. These results, which are both encouraging and disappointing, will be the subject of a more intensive study of the different parameters in question.

[Early therapy of congenital hip dislocation and ultrasonic studies of clinically positive cases--results of a prospective epidemiological study in Brünn].

The early diagnosis of CDH in CSFR an in other countries is discussed from different views. To our opinion only the orthopaedic surgeons are able to ensure the high sensitivity and specificity of the clinical tests. In the Brno-prospective epidemiologic study we have examined 19,879 neonates. The frequency of dislocation and instability was 368 cases (18%). The early treatment with Frejka pillow or Pavlik harness has failed only in one case. The systematic second (6 weeks) and third examination (3 months) discovered 19 late diagnosed cases (0.95%). In the era of conventional diagnosis the usual frequency of CDH in CSFR was 20-30%. The ultrasonographic examination of all neonates is not yet possible in our country; we have examined only clinically positive cases.

[Generalized laxity of the ligaments in children].

Authors reviewed the literature about the nomenclature and classification of ligamentous laxity syndrome. They are using the term "Generalized ligamentous laxity". They prefer the methods, with total body points-system to the extensometry of the fingers. On the basis of 890 healthy children they determined the statistic characteristics of the score of the generalized ligamentous laxity in relation to age and sex. They suggest, on the basis of the obtained data, the way of clinical application.
