Intratracheal fiber glass instillation in rats: IL8 and …
Supernatant was obtained after centrifugation at 1,500 r.p.m for 5 minutes and IL8 levels and lymphocytes nuer were measured. Results The IL8 levels were found to be dose related; the first group had values ranging from 10 to 19.8 pg/ml and the total lymphocytes nuer in the bronchoalveolar lavage fluid ranging from 1,500–1,900 and minimal/slight inflammatory lesions.

Crystalline silicon - Wikipedia
Crystalline silicon (c-Si) is the crystalline forms of silicon, either multicrystalline silicon (multi-Si) consisting of small crystals, or monocrystalline silicon (mono-Si), a continuous crystal. Crystalline silicon is the dominant semiconducting material used in photovoltaic technology for the production of solar cells..
