[Renal hemodynamic in hydronephrosis concurrent with hepatobiliary system disorders, its dynamics in the course of treatment].

This article examines measurements of renal vascular ultrasound in 85 patients with hydronephrosis concurrent with disorders of the gallbladder and biliary tract, depending on severity and dynamics during treatment. The estimation of blood flow changes depending on applied renoprotective and hepatoprotective therapy is provided.

(1α,8β)-6β-Benzo-yloxy-6-dehydroxy-heteratisine from Aconitum zeravschanicum.

The title compound, C(29)H(37)NO(6), was isolated from Aconitum zeravschanicum and exhibits anti-arhythmic activity. It is a derivative of the diterpenoid alkaloid heteratisine and as such the core framework of the mol-ecule contains four six-membered, three seven-membered and one five-membered ring. The chair conformation of one of the meth-oxy-substituted six-membered rings is different from that observed in heteratisine hydro-bromide monohydrate.
