    摘要： The present application describes a novel, advantageous purification method which guarantees the embryonation capability and the viability of a worm egg suspension. The T. suis worm eggs are first treated in a non-embryonated condition in a sulfuric acid solution at about =ph 2. Bacteria and viruses are thereby killed successfully. The germination number of yeasts and fungi is reduced. In a second step, the pH-value is increased and an orally tolerated preservative is added. Yeasts and fungi are thereby killed successfully. The suspension medium used in the second purification step can then be used as a culture medium for additional production (embryonation) and storage.

    摘要： A method for determining the biological activity of embryonated Trichuris eggs is described, in which at least one of the following determinations is carried out: a) Determination and/or confirmation of the stage of the embryonal development of helminth eggs with the aid of quantitative PCR analysis by using suitable marker sequences for ascertaining the copy number of the genomic DNA, b) Determination of the metabolic activity of embryonated helminth eggs by means of biochemical and/or molecular biological methods, c) Determination of the inducibility of gene expression in embryonated helminth eggs, d) Microscopic determination of the motility of helminth larvae in the egg over long periods of observation after pre-incubation at increased temperatures and/or e) Determination of the hatching rate of Trichuris larvae in a laboratory animal, wherein the intact embryonated eggs recovered from the contents of the intestine are quantified compared to an internal standard.

    摘要： An expansion joint system for bridging an expansion joint gap between two spaced-apart underlying stair structures. The expansion joint system includes a movable plate that is connected to a fixed plate through a hinge. The hinge connection permits the movable plate to move in response to thermal movements and seismic events that causes the width of the expansion joint to open to a greater width or close to a smaller width. Following the seismic or thermal event, the hinge connection automatically returns the movable plate to its original position.
