Helicity amplitudes A1/2 and A3/2 for the D13(1520) resonance obtained from the gamma-->p-->-->ppi(0) Reaction.

The helicity dependence of the gamma-->p-->-->ppi(0) reaction has been measured for the first time in the photon-energy range from 550 to 790 MeV. The experiment, performed at the Mainz microtron MAMI, used a 4pi-detector system, a circularly polarized, tagged photon beam, and a longitudinally polarized frozen-spin target. These data are predominantly sensitive to the D13(1520) resonance and are used to determine its helicity amplitudes.

Significant enhanced superoxide anion (O2-) production in vitro by peripheral blood monocytes of lepromatous leprosy patients stimulated with liposome and suppression by C-reactive protein (CRP).

Peripheral blood monocytes (PBM) from normal individuals, infectious mononucleosis (IM) and leprosy patients were stimulated with liposome. The mean and standard error of superoxide anion (O2-) generated in nm/1.5 X 10(5) PBM/well for 5 normal subjects and 3 IM patients was 2.9 +/- 0.5 and 3.1 +/- 0.2, respectively. Monocytes stimulated with 100 ng C-reactive protein (CRP) incorporated into liposome gave values of 3.3 +/- 0.3 and 2.7 +/- 0.1 nm O-2/1.5 X 10(5) PBM/well for normals and IM, respectively. No significant differences in O2- production between liposome and liposome with incorporated CRP were shown. PBM from lepromatous patients demonstrated a significant (p less than 0.01) increase in O2- production with liposome alone compared with tuberculoid patients (3.5 +/- 0.4 vs 1.8 +/- 0.3). The most dramatic suppression of O2- shown when purified CRP was added to the mixtures in all groups examined [0.4 +/- 0.1 (500 ng), 0.3 +/- 0.0 (500 ng), 1.5 +/- 0.1 (100 ng), and 1.3 +/- 0.6 (100 ng) nm O2-/1.5 X 10(5) PBM/well for normals, IM, lepromatous, and tuberculoid, respectively]. Results of O2- formation with incorporation of CRP into liposome as compared with liposome alone had no significant effect on PBM of lepromatous or tuberculoid patients. It is suggested that CRP may play a significant role in regulation of oxygen free radicals formed during acute and chronic inflammatory episides.

[Type distribution of hyperlipoproteinemias in 645 diabetics].

On 645 diabetics of the treatment-groups diet (n = 180), sulfonylurea therapy (n = 250), biguanide therapy (n = 50), and insulin therapy (n = 165) the concentrations of cholesterol and triglyceride were determined and the lipoprotein electrophoresis was carried out. 29% of the diabetics showed hyperliproteinaemias, males and females in the same frequency. In about 54% the type IV was observed most frequently, then followed the types IIb with 25% and the type IIa with about 13%. The dependence of triglycerides on the metabolic situation and the body weight was proved in diabetics. The cholesterol values were independent on form of therapy, body weight and metabolic situation. In the group with sulfonylurea in about 49%, in the group with insulin in about 37% and in the group with diet and buformin only in about 32% a hyperlipoproteinaemia was proved. The opinion is represented that the high percentage of hyperlipoproteinaemia in diabetics and the connected with this additionally increased risk for vascular complications should lead to the introduction of diagnostics and therapy of hyperlipoproteinaemia into the programme of the diabetes dispensaries of the GDR. For the treatment of diabetes the principle should be taken into consideration that a diabetes is optimally regulated only then, when apart from the blood sugar values also the blood fats are within the normal.

Freeze-drying of a purified human diploid cell rabies vaccine.

A rabies vaccine prepared in human diploid cell strains was purified by continuous-flow sucrose density gradient centrifugation. The peak fractions containing 35-40% sucrose were diluted with a stabilizer consisting of degraded gelatine in a Tris-EDTA-buffer, and then inactivated with beta-propiolactone and freeze-dried to a residual moisture of approximately 2.5%. This vaccine was stable as proved by accelerated stability tests.

Effect of neuraminidase on potency of inactivated influenza virus vaccines in mice.

The protective effect of neuraminidase was studied in a mouse protection test using isolated neuraminidase of A2/Aichi/68(H3N2) virus and the complete recombinant virus A/eq(Heq-1)-HK(N2) as antigens. Immunized mice were protected against A2/Aichi(H3N2) challenge virus; however, the protection rate was low in comparison to animals immunized with comparable amounts of the complete A2/68(H3N2) virus9 Furthermore there was no cross-protection against A2/Asia/57(H2N2) challenge virus. The protective effect of neuraminidase was not impaired by Tween-ether treatment of the A/eq(Heq-1)-HK(N2) recombinant virus.

International conferences on violence against women.

Violence against women has been written about as an international health issue. Since 1975 international conferences and organizations have addressed the problems. The resulting resolutions requested that measures be taken to eliminate violence against women.

Results of the single-radial-diffusion test with formaldehyde-treated influenza virus.

We found reduced values for formaldehyde-treated influenza virus in the single-radial-diffusion test by comparison with non-treated virus. The reduction correlates with the formaldehyde concentration. Hemagglutination and neuraminidase activities were not affected by the same treatment. We therefore suggest that this reduction is not based on antigen destruction.
