After discussion of the biologic basis of echographic tissue differentiation and of the required standardization of the ultrasonic diagnostic device by means of tissue models (citrated blood), a technical standard is presented. This solid tissue model, which can be used an unlimited number of times, enables the investigator to determine or check the tissue… (More)
Under appropriate conditions, both surface areas and cation exchange capacities of clay minerals can be measured by absorption of methylene blue from aqueous solutions. The method has been applied to two kaolinites, one illite, and one montmorillonite, all initially saturated with Na + ions. For Na-montmorillonite, the total area, internal plus external, is… (More)
Dyslexia without agraphia is a highly complex cerebral malfunction. A posttraumatic case is considered. The localisation of the lesion is remarkable and leads to the conclusion that associative paths have been largely destroyed.
During the past 10 years, clinical echography has been developed to a valuable and even indispensable examination method with which more than 25 various conditions and diseases or groups of lesions within the globe can be differentiated (the majority of them with a high degree of realiability and accuracy). Two signigicant steps to this end were the… (More)
Systemic beta-blockade after single doses of ophthalmic beta-blockers (one drop in each eye) was investigated in healthy volunteers in two randomized, double-blind, crossover, placebo-controlled studies. beta-Blockade was evaluated by displacement of the bronchodilator (specific airway conductance), positive chronotropic (heart rate), and tremorogenic… (More)
The echografic criteria for a differential diagnosis between malignant melanoma of the choroid and a metastasis are described. In particular, the reflectivity of these lesions differs, so that malignant melanoma can be diagnosed with a high degree of accuracy, even in cases with primary tumors where a metastasis in the choroid is suspected.
According to the Lincoff's procedure, a cryoprobe is used for the localization of retinal holes. A cryo-marker developed for Keeler-cryoprobes simplifies the marking of the scleral impression of the cryoprobe, which is often invisible after thawing. The cryo-marker is fixed on the cryoprobe before cryotherapy. During thawing the toothed ring of the… (More)
