Potassium octatitanate

Typical components in a fiietion material are shown in Table 13.4. The formulations are eured at high pressure and temperatures. It has been found out that potassium hexatitanate and potassium octatitanate fibers should be used together. In this way, the performance of the mixture can be increased considerably. 

Crocidolite or potassium octatitanate whisker instilled intratracheally into male Wistar rats (2 mg in saline) peaked levels of IL-la mRNA in alveolar macrophages at 1 month thereafter (Tsuda et al. 1997). 

Four weeks after intratracheal instillation of 2 mg of respirable potassium titanate whiskers into male Wistar rats RNA extracted from LPS stimulated alveolar macrophages expression of IL-la was increased (Tsuda et al. 1996,1997). The expression of IL-la mRNA was by fibres was greatest in potassium octatitanate whisker > UICC crocidolite > UICC chrysotile > refractory ceramic fibre-instilled rat alveolar macrophages. The levels of IL-la and TNF-a mRNA in alveolar macrophages (expressed in their ratio to P-actin) peaked at 1 month and 3 days after exposure to octatitanate, respectively.
