In vitro macrophage cytotoxicity of five calcium silicates

In vitro macrophage cytotoxicity of five calcium silicates. Skaug, V.; Davies, R.; Gylseth, B. (Inst. Occup. Health, Oslo 1, Norway).Some commonly used reagents like 9001-45-0 and 1344-95-2 are used in this experiment. Br. J. Ind. Med., 41(1), 116-21 (English) 1984. CODEN: BJIMAG. ISSN: 0007-1072. DOCUMENT TYPE: Journal CA Section: 4 (Toxicology) Five Ca silicate minerals (US and Finnish wollastonite [13983-17-0], b-wollastonite [10101-39-0], and tobermorite [66732-74-9]) with defined morphol. and chem. compn. were compared for their cytotoxic and lysosomal enzyme-releasing effects on unstimulated mouse peritoneal macrophages in vitro. Synthetic tobermorite was cytotoxic towards the cells, and the naturally occurring wollastonites induced selective release of b-glucuronidase [9001-45-0] from the cells. .

CLASS: IC: C08L067-02; C08K003-00; C08K007-14. ICI: C08L067-02, C08L051-00, C08L069-00, C08L033-04. APPLICATION: JP 82-45981 23 Mar 1982. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) The title compns. comprise a polymer component contg. mostly poly(tetramethylene terephthalate) (I) [24968-12-5] 40-95, an inorg. filler with av. 9003-56-9 and 24968-12-5 are cas registry numbers of chemicals which are used as reagents here. particle diam. (D50) 2-10 m 4-59, and another inorg. filler with D50 <2 m 1-25%. The compns. exhibit excellent surface smoothness properties. Thus, I (limiting viscosity 0.93) 60, wollastonite [13983-17-0] (D50 8 m) 30, and TiO2 (D50 0.25 m) 10 parts were mixed for 5 min to give a compn. with excellent appearance in sink and surface smoothness. .
