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.

The invention relates to an effervescent tablet for preparing a mouth rinsing solution, wherein the effervescent tablet exhibits a high release rate of budesonide. A high availability of the active ingredient during use as a mouth rinsing solution on the inflamed mucosa of the upper digestive tract is thereby achieved. The advantage of the formulation according to the invention lies in the bioavailability comparable to oral forms of administration, which allows the formulation to be used safely over an extended period of time.

摘要:
A head wheel is rotated at a predetermined, essentially constant speed within a tape cylinder over which a tape is guided in a spiral path, on which video signal tracks are recorded in inclined track portions. The instantaneous position of the head wheel is determined, for example by a tacho generator applying signals to a counter, phase-synchronized by the outputs from the head wheel tacho generator. The instantaneous position of the tape is determined, for example from sensing the cross modulation of signals derived from the head as the head crosses from one track portion to another, or by sensing the phase jump of the pulse sequence of the horizontal synchronization signals; the two position signals are combined in a logic stage so that a line address can be derived of a signal transduced at any one instant by said head from an incremental area of the tape, the signal being associated with the line address for storage, for example in a memory for subsequent re-recording or reproduction at a time relation (slow motion or fast motion) differing from the original recording speed.

The invention provides an apparatus for producing video frequency color value signals which correspond to a desired arrangement of vertical or horizontal color bars on a television screen. In the case of vertical color bars the apparatus derives during each line period an identical series of pulses having a multiple of the line frequency. Each series of pulses is applied to a binary counter which provides as output a sequence of sets of binary signals. This sequence of sets of binary signals is translated by a pre-programmed store into a further sequence of sets of binary signals, these latter sets of signals being applied to a digital-to-analogue converter adapted to derive therefrom corresponding sets of color value signals. Each set of color value signals defines a differently colored line segment. The effect of this operation over a plurality of successive line periods is to build up a number of vertical color bars each composed of vertically adjacent line segments of the same color derived from identical sets of color value signals occurring in successive line periods.In the case of horizontal color bars the apparatus operates in a similar manner except that the series of pulses initially produced is at a fraction of the line frequency and is derived once for each field period rather than once for each line period.

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.
