Figure 6.

Nitric oxide (NO) production in isolated adipose tissue arterioles collected on the day of surgery. Representative images by fluorescence microscopy of NO generation conditions at baseline and after incubation with L-NAME, PEG-CAT, vitamin D, vitamin D plus L-NAME, and vitamin D plus PEG-CAT in VAT arterioles (A) and SAT arterioles (B). Charts represent NO fluorescent signals that were measured and expressed in arbitrary units using NIH Image J software. All measures are represented as means ± SE; ₸ p < 0.05 comparing L-NAME with baseline, † p < 0.05 comparing vitamin D with baseline, * p < 0.05 comparing L-NAME + vitamin D with vitamin D alone.
