[The levels of cortisol and glycosaminoglycans in patients with uveitis in rheumatic diseases].

The serum levels of cortisol and glycosaminoglycans (GAG) were studied in patients with uveitis in rheumatic diseases (RD). Among the patients with this pathology, there was a more preponderance of persons with low cortisol levels. In acute uvitis in the presence of RD, the mean serum content of this hormone was significantly lower than that in infectious and idiopathic uveitis.

[Role of the renin-angiotensin system of the eye in the pathogenesis of diabetic retinopathy].

Numerous experimental and clinical studies indicate the involvement of the renin-angiotensin system in the development and progression of diabetic organ pathology. ASD is the main biochemical mechanism by which vasomotor and angiogenic reactions are realized. It interacts closely with its antagonist, the kallikrein-kinin system.
