Effect of intra-arterial sodium nitroprusside on intracranial pressure and cerebral autoregulation.

In cats with normal intracerebral pressure (ICP), administration of sodium nitroprusside (40 micrograms/Kg/min) through the common carotid leads to an increase of ICP, which is attributed to vasodilatation. When ICP is raised gradually to 40 mmHg by intracisternal infusion of artificial CSF prior to the application of SNP, increments of ICP due to SNP become smaller. This reduced vasodilatatory response can be attributed to either a decrease in cerebral perfusion pressure or a direct influence of intra-arterially administered SNP on the autoregulatory capacity of cerebral vessels.

An evaluation of coronary regulation by the 99mTc bolus technique.

A new non-invasive method for investigating total coronary blood supply is presented. This method is based on the principle of indicator dilution of a radio-nuclide bolus (99Tc), requiring a scintillation camera with high sensitivity and high picture resolution. The first findings obtained from 83 patients are shown. With 4.61 +/- 1.19% of cardiac output the mean values of the rates of coronary perfusion obtained at rest in subjects with a normal heart differed significantly from those obtained for patients with certain coronary occlusions (8.18 +/- 3.99% of cardiac output) and from those obtained for hypertensive patients (Stages I-III). Double examinations carried out on 20 patients yielded an adequate reproducibility. The mean deviation of the double examinations from one another was 16%.

[100 Years of anthropological examination of school children in Jena (GDR)].

The present paper gives a review of the aims and the importance of the anthropological examinations on Jena school children, which have been carried out since 1880. It is shown that secular acceleration of stature and body weight was greater between 1964 and 1975 than the changes found in previous investigations. Special importance is attributed to a comparison of the results of the investigation made in 1880 with those of 1975.
