To provide an immortalized capillary pericyte line which maintains the original function / property of the cell line-deriving tissue, its establishment method, and the screening method for useful substance using the immortalized capillary pericyte line. Cerebral tissue of a transgenic rat carrying the large T antigen gene of SV40 thermo-sensitive mutant line tsA58 is homogenized and the resultant brain capillaries are treated with protease, thus obtained brain capillary cells are subcultured to establish an immortalized cell that expresses SV40 thermo-sensitive large T antigen, PDGF receptor β, and Angiopoietin-1. In addition, the immortalized vascular pericyte line has ability to deposit calcium on matrix by dense culture.

When fly ash is added to a cement kiln to materialize it after being desalinated by washing, scale is prevented from growing in a dissolution reaction apparatus depositing calcium-containing compounds dissolved in slurry, and the fly ash is effectively used as a cement material. A dissolution reaction apparatus according to the invention comprises: a dissolution tub 3 for dissolving powder material, a wet dust collector 5 for collecting powder material and mist while reacting slurry S in the dissolution tub 3 with gas G and returning the collected powder material and mist to the dissolution tub 3. A second wet dust collector 7 can be provided for collecting powder material and the like accompanying to the gas G discharged from the wet dust collector 5, and both the wet dust collectors 5, 7 can be vertical type and mounted independently with each other on the dissolution tub 3. The slurry S and the gas G can react with each other with parallel flow by feeding the slurry S and the gas G to an upper portion of the first wet dust collector 5, or the powder material and the like accompanying to the gas G may be collected with counter flow by feeding the gas G discharged from the dissolution tub 3 to a lower portion of the second wet dust collector 7.

The invention relates to a construction method for high-pressure spraying microbial bacterial liquid to deposit calcium carbonate to treat landslides. The plan includes the following construction steps: cleaning the slope surface of a potential landslide body, and arranging an operation platform; Drilling to form a plurality of liquid injection holes; inserting a steel flower tube closed at the bottom into each liquid injection hole; injecting microbial bacterial liquid into each steel flower tube; elevating the steel flower tube according to the set speed until it is lifted to a soft sliding Stay at the surface for a set time and then continue to lift the steel flower tube; stop the microbial injection when the bottom elevation of the steel flower tube exceeds the weak sliding surface elevation by at least 1m; pull out each of the steel flower tubes, wait for the bottom of each injection hole. After the microbial deposition of calcium carbonate is completed, microbial bacterial liquid injection and soil filling are performed in each liquid injection hole again. The invention has the advantages of reducing the damage to the mountain and the ecological environment, and has the advantages of fast construction speed and low construction cost.
