Figure 2. Grading of thrombin-induced pulmonary thromboembolism.

Figure 2

(a) Grading of pulmonary embolism according to vessel size and degree of vessel obstruction (GI-IV). Small vessel (maximum diameter <150 μm: GI < 50% vessel obstruction, GII > 50% vessel obstruction) or large vessels (maximum diameter >150 μm: GIII < 50% vessel obstruction, GIV > 50% vessel obstruction). Bar indicates 50 μm. (b) Mean number of pulmonary embolism per lobe after intravenous thrombin injection, overall and according to embolism grade compared to saline injection (n = 5 mice per group, Data are shown as mean ± s.e.m.; p < 0.05, Mann-Whitney U Test; ns = not significant).
