ABSTRACT
Electrostatic stresses that can influence the observed signal with stress-optical constants form a contribution to the quadratic electro-optic (Kerr) effect measured at low frequencies. A new formula is proposed to correct for the influence of these stresses in order to obtain the true Kerr constant.

In patients with primary hypertension, intravenous administration of 150 mug Clonidin caused a decrease in arterial pressure, renin activity, RPF, GFR and electrolyte excretion. Activation of intracerebral adrenergic alpha-receptors and diminished sympathetic outflow seem to be responsible for the decrease of renin release.

1086 patients with acute viral hepatitis (AVH) including both children and adults were followed up clinically and biologically for 1-1.6 years after onset. Length of hospitalization and time intervals until return of normal laboratory test values were correlated with the presence of HB8Ag. The evolution of HB8Ag positive AVH was found to be more severe and protracted, especially in the case of HB8Ag persistence. The data point to the fact that ambulatory medical surveyance is recommendable in AVH, necessary in AVH type B and compulsory in the case of HB8Ag persistence.

From 200 acute viral hepatitis patients serum samples were collected successively, at various intervals. In 192 patients one single hepatitis B-antigen (HB-Ag) subdeterminant ("ad" in 37.6% and "ay" in 62.4% of the cases) occurred and persisted during the entire course of the disease. The remained 8 patients (4%) showed an alternation of HB-Ag subdeterminants. The possible causes of this alternation are discussed in detail.
