[Cardiac failure treatment with berlipril: effects on hemodynamics, neurohumoral status and activity of free radical lipid peroxidation].

Aim: To test the ability of ACE inhibitor berlipril to control neurohumoral hyperactivation and reestablish balance between oxidant and antioxidant systems in patients with ischemic heart disease (IHD) associated with heart failure (HF).

Materials And Methods: 145 patients (mean age 51.5 +/- 3.

Comparison of influenza viruses isolated from man and from whales.

Four isolates of influenza virus strains from Moscow and Habarovsk that caused outbreaks of influenza in November and December 1977 in several cities of the USSR were studied and their haemagglutinins and neuraminidases were compared with those of other human and animal influenza viruses including A/whale/Pacific Ocean/76. In H1 tests these isolates, designated A/USSR/77, reacted with immune serum against A/FM/1/47 (H1N1) to the homologous titre, and with antiserum against A/whale/PO/19/76 virus to 1/8 of the homologous titre. In neuraminidase inhibition tests all A/USSR/77 isolates showed the presence of human N1 type neuraminidase, more closely related to A/sw/New Jersey/76 (Hsw1N1) than to A/FM/1/47 (H1N1) virus.
