摘要:
A television camera device having an image pickup structure, with a plurality of control units, for producing an optimum image output signal that (i) corresponds to a received object image (ii) is in accordance with one of a plurality of predetermined image pickup environments. The device includes a memory for storing scene files which contain image pickup control data for the plurality of the predetermined image pickup environments, and a mode setting structure for selecting a particular scene file from the scene files stored in the memory. Further, the device includes a timer operatable in response to the selection of a scene file by the mode setting structure, and an operation structure, coupled to the image pickup structure, the memory, the mode setting structure, and the timer. The operation structure sequentially outputs to the image pickup structure intermediate image pickup control data which is between the control data of the pre-selection scene file and the control data of the post-selection scene file. The operation structure changes the intermediate control data is discrete increments at a frequency determined by the timer when the scene file is selected by the mode setting structure.
摘要:
A quantitative analysis of 3-oxo-5.beta.-steroid is carried out by acting 3-oxo-5.beta.-steroid.DELTA..sup.4 -dehydrogenase on a sample in the presence of a reducing chromophoric agent, and measuring the optical density of the chromophoric substance thereby produced. A typical reducing chromophoric agent is a tetrazolium compound. The invention also provides a reagent for the quantitative analysis of 3-oxo-5.beta.-steroid comprising 3-oxo-5.beta.-steroid.DELTA..sup.4 -dehydrogenase and a tetrazolium compound. The analysis and reagent provide a simple and reliable method for a liver function test.
摘要:
A 3.alpha.-hydroxysteroid contained in a sample can be quantitatively analyzed by causing a 3.alpha.-hydroxysteroid dehydrogenase to act on the sample in the presence of nicotinamide adenine dinucleotide, causing tetrazolium or a salt thereof, an electron carrier substance, and 3-oxosteroid-.DELTA..sup.1 -dihydrogenase and/or 3-oxosteroid-.DELTA..sup.4 -dehydrogenase to act on the thus-obtained reaction product, and then quantitatively analyzing the resultant formazan.
