The blood was taken on gestation days 140-237 and 238-280. No significant changes in renin concentration were observed during normal pregnancy (p=0.423). The level of angiotensin II increased during normal pregnancy from 9.7±1.2 to 14.7±1.9 pg/ml (p=0.019). On the contrary, angiotensin (1–7) concentration decreased from 771.1±44.2 to 390.7±13.9 pg/ml (p<0.001). The shift in the proportion between vasoconstrictor angiotensin II and vasodilaltor angiotensin (1–7) attests to high predisposition of pregnant women to hypertension-related complications.

© 2018, Springer Science+Business Media, LLC, part of Springer Nature. Objective. To study the association between the kynurenine-3-monooxygenase (KMO) gene and depression. Materials and methods. Polymorphic loci rs2275163 (C/T) and rs1053230 (A/G) of the KMO gene were studied in patients with depression (study group) and mentally healthy subjects of comparable gender and age (control group). Results and conclusions. The rs2275163 polymorphism was not associated with depression. An association between the rs1053230 polymorphism and depression was found. The frequency of the GG genotype, linked with lower KMO activity and increased kynurenic acid levels in patients with endogenous psychoses, was greater in the study group than the control group (p = 0.001, OR 2.8 (95% CI 1.73–4.24). thus, the GG genotype can be regarded as a risk allele for developing depression.
