A method and apparatus of automatically reprocessing a specimen for microscopic examination is disclosed. Processing of a specimen for microscopic examination involves fixation of the specimen and preparation of the embedded specimen from the fixed specimen. There are instances where, once a specimen has been processed, it is necessary to reprocess the specimen due to contamination of reagents during processing or inadequate fixation. The system automatically reprocesses a specimen by removing residual embedding material from the specimen with a clearing agent, removing the clearing agent with a dehydrating agent, and removing the dehydrating agent with an aqueous fluid.

The present invention is a method for determining the location of and distinguishing aggressive diamonds from active diamonds on a diamond conditioner disc, comprising: (a) contacting a diamond conditioner disc with a hard surface, wherein the diamond-containing side of the diamond conditioning disc is facing the hard surface, (b) pushing the conditioner disc a sufficient distance that all diamonds could possibly be scratching the surface at the same time and at least a distance corresponding to the length of the said diamond conditioner disc (c) observing number and position of the scratches left by diamonds on the hard surface to determine the number and position of active diamonds on the diamond conditioner disc, and (d) selecting the diamonds, the marks for which are the most pronounced and which comprise 50% or more of the total furrow area observed for all of the active diamonds in descending order of furrow are plus any diamonds in excess of the number needed to achieve said 50% or more whose individual furrow area is 2% or more, which diamonds are determined to be aggressive diamonds, or impressing the diamond conditioner disc under a load onto a hard surface and the impression of the most aggressive diamonds in the hard surface being confirmed by microscopic examination to in turn confirm the position and aggressiveness of the aggressive diamonds observed or (e) contacting a diamond conditioner disc with a hard surface, wherein the diamond-containing side of the diamond conditioning disc is facing the hard surface, (f) pushing the conditioner disc a sufficient distance that all diamonds could possibly be scratching the surface at the same time and at least a distance corresponding to the length of the said diamond conditioner disc (g) observing number and position of the scratches left by diamonds on the hard surface to determine the number and position of active diamonds on the diamond conditioner disc, (h) the hard surface further comprises a layer of contrasting material such that when the diamond conditioner disc moves across the hard surface, the said diamond conditioner disc crosses the limits of the layer entirely from one end to the other and scratches the layer of contrasting material on the hard surface thereby leaving a visible mark, (i) the said layer is between 8 and 15 microns thick and (j) selecting the diamonds which cut entirely through the said layer allowing backlighting to be easily viewed.

The present invention provides Bacillus vallismortis SZ-4, which has the preservation number of CGMCC No.8273. According to the present invention, the strain grows on a beef extract-peptone (NB) culture medium in a single cell reproduction growth manner to form bacterial colonies, and the bacterial colonies have characteristics of round shape, milk white color, slightly elevated center, and moist and transparent surface; microscopic examination results show that the Bacillus vallismortis SZ-4 has a rod shape, has flagella, has a size of 0.7-0.82*1.6-2.2 mum, presents the positive Gram staining effect, has spores, and can grow on a beef extract-peptone (NB) culture medium containing 2-5% of NaCl, wherein the beef extract-peptone (NB) culture medium comprises: 3.0 g of a beef extract, 10.0 g of peptone, 5.0 g of NaCl, 17 g of agar and 1000 ml of water, and the pH value is 6.8-7.2; and the Bacillus vallismortis SZ-4 provides significant antagonism effects for pathogenic bacteria causing ginseng root rot, blight, sclerotinia sclerotiorum and botrytis cinerea. The present invention further provides an application of the Bacillus vallismortis SZ-4 in prevention and control of plant fungal diseases or preparation of microorganism preparations for prevention and control of plant fungal diseases.

A quantitative fecal examination apparatus includes a fecal collector removably mounted on a container base, having the fecal collector provided with a suction portion for sucking a fecal specimen into the collector and then the fecal specimen is disposed into the container base for examination test or for sucking the fecal specimen for further laboratory test including microscopic inspection, and having a quantitative design in the examination apparatus for collecting the fecal sample in a pre-set quantity for more precise examination.
