The effects of R 76 713 on steroidogenesis were studied in primary cultures of four different human cell types i.e. ovarian granulosa cells, adipose stromal cells, testicular cells and adrenal cells. In human granulosa cells aromatization of [lβ,2β

The so-called diphasic and other irregular acoustic reflex patterns for the susceptance, conductance or admittance, can often be explained if a monophasic shape is assumed for the resistance and the reactance reflex patterns. It is shown that patholo

The magnitude and the sign of the rate of pressure change, used to record tympanograms, have a pronounced effect on the aspect of these curves. For diagnostic purposes, abnormal tympanograms are often more evident at high rates (30 mm H2O/sec). Stabl

Two-component tympanometry with a high probe-tone frequency enables a better distinction to be made between mobile but normal middle-ear systems and middle-ear systems suffering from necrosis, luxation, or disruption. Susceptance and conductance tymp

A comparative study between the monobloc tympano-ossicular implant and the classical columellar technique is made. Although both give satisfactory audiometric results, the follow-up of the columellar restoration showed some post-operative disadvantag

The so-called W-notching of tympanograms can be explained if some realistic assumptions are accepted about the dependence on the pressure in the external auditory meatus of the acoustical resistance and the acoustical reactance at the eardrum. Sets o

In this experimental study a procedure is developed which enables the conversion of susceptance and conductance tympanograms to reactance and resistance tympanograms. Special attention was given to the subtraction of the ear canal admittance. The pro

The origin of the tail asymmetry of susceptance tympanograms was investigated. A flow-measuring device enabled an accurate determination of ear-canal volume changes produced during tympanometry. From these measurements one finds that not only is the

The existence of two kinds of diphasic acoustic reflex patterns for human ears is proved experimentally. The “false” irregular patterns, which originate from the transformation of monophasic resistance and reactance responses, obey the properties

The diagnostic value of susceptance, conductance, resistance, reactance, admittance and phase-angle tympanograms is compared. Phase-angle tympanograms seem to be best suited for the discrimination between normal W patterns and broad irregular curves
