GSTM1 and hematocrit: Furthermore, quantification of EB- and Hb-contents demonstrated that “+GSNO with IVT” significantly prevented the EB-content (p < 0.0363) and Hb-content (p < 0.0006) as compared to the “+Veh with IVT” controls (Figure 6B,C), thus evidencing that low-dose GSNO nebulization attenuates the detrimental effects of late-IVT on the BBB integrity and reduces the risk of HT in diabetic mice.
