Evaluation of the effectiveness of vaccination against diphtheria among medical staff of the chair and the Jagiellonian University Hospital of Infectious Diseases in Cracow, Poland. Some epidemiological observations.

In Poland, twenty-five cases of diphtheria, mostly among adults (including five foreigners) in the region adjacent to the eastern border were registered in the years 1992-1996. In 1993-1994, because of the threat of diphtheria infection, 41 healthy members of the medical staff of the University Hospital of Infectious Diseases in Kraków, mainly women aged 25-57 years were immunized with Td and d vaccines with a 6-month interval between courses. Prior to vaccination, 17(41%) individuals showed a lack of diphtheria antibodies as determined with a passive haemagglutination test.

[Drug resistance of Helicobacter pylori strains isolated from patients with inflammation of stomach mucous membrane and peptic ulcer of stomach and duodenum].

Twelve strains of H. pylori were tested. They were isolated from biosamples from 23 patients with stomach inflammation (16 persons) and stomach (3) and duodenum peptic ulcer.

[Bioavailability of griseofulvin in the form of liposomes].

Liposomes containing griseofulvin have been prepared by shaking method. Lecithin and cholesterol were used to compose phospholipid bilayer of liposomes. The suspension of liposomes in 0.

[Reaction of dental methacrylate material in in vivo tests--selected hematologic and immunologic indices].

Wistar rats were implanted subcutaneously with 2.5 x 6 mm cylindrical matrices, made from the home-made metacrylate material Akpol S, and, for comparative purposes, with the imported materials Trevalon and Superacryl. At different time intervals quantitative and qualitative analyses of the picture of leucocytes and of blood plasma proteins were carried out in groups of animals implanted with the above-mentioned materials and in a control one.

[Histopathologic evaluation of the reactivity of soft tissue to dental acrylate implants--in vivo examinations].

Wistar rats were implanted subcutaneously with samples of the home-made metacrylate material Akpol S and, for comparative purposes, with samples of the imported materials Trevalon and Superacryl. Throughout a period of 7 weeks, at 7-day intervals, sections of the tissues surrounding implants were collected from the animals and examined histopathologically. No differences in the character of the inflammatory reaction ensuing around the implants made from the three tested materials were observed.
