[Prevention of recurrent infection of the upper and lower airways. Multicenter, open study over three months].

In a multicenter open study involving 620 patients suffering from recurrent infections of the upper and lower respiratory tract aged between 12 and 89 years, the tolerability of an oral bacterial lysate was investigated. On the basis of the nature and frequency (1.9%) of adverse effects, and an analysis of the laboratory investigations over an observation period of three months, overall tolerability was adjudged to be excellent.

[Detection of cutaneously administered flufenamic acid in the inner space of the knee joint].

Ten patients who were scheduled for surgery due to an internal damage of the knee joint, were treated 2 days before operation 3 times daily with an ointment containing flufenamic acid (Mobilisin spezial). At the time of operation, plasma and synovial fluid, tissue samples from the synovial membrane, Hoffa's fat pad and-- as far as possible--meniscus and articular cartilage were taken. Until 72 h after the operation, urine samples were collected.
