diabetes is characterized by a nitric oxide deficiency at the wound site. diabetes is a factor that influences all stages of wound healing. in animals with acute experimental diabetes induced by streptozotocin (stz), the early inflammatory responses after wounding is impaired, fibroblast and endothelial cell proliferation is reduced as well as accumulation of reparative collagen and gain in wou...

Under normal physiological conditions activation of nitric oxide synthases produces both nitric oxide and superoxide in equimolar concentrations (Figure 1). We propose a hypothesis that in hypoxia-reoxygenation injury this balanced co-production of nitric oxide and superoxide is disturbed and results in pathological effects. Specifically, under hypoxic conditions nitric oxide synthase is activa...

objective(s) the fractions of candida albicans have been used as an immunomodulator. the present work assessed the effect of different fractions of c. albicans on nitric oxide (no) production by mice peritoneal macrophages. materials and methods cell wall and cytoplasmic fractions of c. albicans atcc 10321 strain were extracted. mice peritoneal macrophages were purified and cultured. different ...
