Abstract: The present invention provides a pharmaceutical composition which can permit a sparingly water-soluble drug substance to be solubilized or dispersed in a pharmaceutically allowable liquid medium (e.g., fat emulsion, etc.), characterized in that said pharmaceutical composition contains (a) a base (e.g., polyethylene glycol, etc.), (b) a sparingly water-soluble drug substance and (c) a fatty acid or its pharmaceutically allowable salt. The pharmaceutical composition can be mixed with a pharmaceutically allowable liquid medium to produce a pharmaceutical preparation for administration, such as an injectable solution, etc., wherein mixing can be performed for a shortened period of time and the sparingly water-soluble drug substance can be uniformly solubilized or dispersed in a liquid medium.

Abstract: A complex comprising a lipid and a conjugate of GPIb and lipid having a functional group, and use thereof. The GPIb-lipid complex of the present invention is extremely useful as a platelet substitute, a pharmaceutical agent for the prophylaxis and treatment of angiopathy, vascular damages and thrombosis, a diagnostic for vWF deficiency and the like, a biological or medical reagent, a reagent for screening platelet aggregation suppressant or antithrombosis, and the like. The GPIb-lipid complex of the present invention is also useful as a diagnostic for finding the location of vascular lesion or thrombus formation, or a therapeutic agent therefor, since it accumulates at vascular lesions.

Abstract: A compound of the following formula ##STR1## wherein m is an integer of 1 to 3, R.sub.1 and R.sub.2 are the same or different and each is hydrogen atom or lower alkyl, and R.sub.3, R.sub.4, R.sub.5 and R.sub.6 are the same or different and each is hydroxy or a group of the formula ##STR2## (wherein n is 0 or 1, X is --NH-- or --O--, Y is alkylene, A is hydrogen atom, lower alkyl, lower alkoxy, halogen atom or trifluoromethyl, and B is alkyl or alkenyl), with the proviso that two or three of R.sub.3, R.sub.4, R.sub.5 and R.sub.6 are hydroxyl groups and that when two of them are hydroxyl groups, the cases where R.sub.3 and R.sub.5 are hydroxy, and R.sub.4 and R.sub.6 are hydroxy are excluded; a complex compound comprising said compound and a metallic atom; and a diagnostic agent containing said complex compound. The above compound is useful as a chelating agent and the complex compound comprising said compound and a metallic atom exhibits superior characteristics as a contrast medium for image diagnosis.

Abstract: A scanner is so arranged that a quantity of light reaching a CCD sensor can be kept constant with a change in reading position. In case a light source and a reading optical unit are driven independent of each other, variations in feed amount inevitably occur. To deal with it, a test chart of a specified length is first read to measure moving amounts of the light source and the reading optical unit. Then, the reading optical unit is moved by a predetermined amount. The light source is moved as effecting a correction based on the moving amounts initially measured. Then, a one-line reading process is carried out to scan an image on a document.

Abstract: The concentration of an organic chlorine compound contained in a gaseous medium is measured in situ by feeding the gaseous medium to a reaction zone and oxidizing the chlorine compound to produce a reactive gas capable of reacting with a chemiluminescent compound to cause chemiluminescence. The reactive gas is contacted with the chemiluminescent compound contained in a cell to cause chemiluminescence whose intensity is proportional to the amount of the reactive gas produced by the oxidation of the organic compound. The concentration of an organic chlorine compound contained in an aqueous medium may also be measured by the similar method after separating the organic chlorine compound as vapors from the aqueous medium. A device suitable for the above measurement is also disclosed.

Abstract: A transfer ribbon feed arrangement for use in a transfer type recording apparatus which transfers onto a recording sheet by sequentially feeding the transfer ribbon includes a feed roller disposed on the feed side of the transfer ribbon for feeding the transfer ribbon from the feed roller, a take-up roller for winding up the transfer ribbon around it and a tension unit disposed on the feed side of the transfer ribbon for applying a constant load on the transfer ribbon to keep it under a constant tension.

Abstract: According to the recording apparatus of the present invention, recording papers are wound by the winding member while the end portions of the recording papers are tightly held. The recording papers can therefore be correctly reciprocated. Furthermore, before recording is effected by the recording head, the recording papers are one wound back by the winding member to an initial position, thereby removing strains or deflections of the recording papers. Also, in the case of a color printer of thermal transcription, images in each of the four colors can be accurately overlapped without disagreement.

Abstract: Acetylsalicylates with basic amino acids such as DL-lysine is stabilized in the form of solid preparation by admixing anhydrous calcium chloride therewith. The preparation containing calcium chloride is prevented from hydrolysis and can be stored for a long period of time even at a relatively high room temperature. The preparation is further prevented from discarolation when glycine is added thereto.
