Use of silver nanowires to determine thresholds for fibre length-dependent pulmonary inflammation and inhibition of macrophage migration in vitro

Table 2 Summary of the length-dependent effects of fibres in the lungs

* BAL granulocytes: <0.5 million (+); 0.5-1.0 million (++); 1–2 million (+++).
** Lung histology subjectively scored on the basis of the severity of lung inflammation (see results).
*** Frustrated phagocytosis on the basis of evaluation of cytospins for presence of frustrated phagocytosis.
**** Impaired migration on the basis of degree of significant impairment compared to control (see Figure 6A).
***** Δ kinase phosphorylation based on subjective examination the levels of phosphorylation of the treated compared to the control levels of phosphorylation (see Figure 7). NA = not applicable.
