1. Análise da produção do antitumoral retamicina em cultivos contínuos de Streptomyces olindensis ICB20 utilizando planejamento fatorial. / Analysis of the production of the antitumor drug retamycin in continous cultures of Streptomyces olindensis ICB 20 using factorial desing.
The aim of this project was to study the production of retamycin in bench-top bioreactors by Streptomyces olindensis ICB20 in continuous cultures in order to evaluate the influence of the agitation rate (N=300, 500 or 700 rpm), the dissolved oxygen concentration (20%, 50% or 80%) and the specific growth rate (µ=0.05, 0.15 or 0.25 h-¹). A full factorial exp

5. Antibodies to cellular antigens in Sjögren's syndrome.
An extract of human lymphocytes from continous cell culture was used as the antigen source to detect antibodies in sera of patients with Sjögren's syndrome (SS). Using double diffusion in agarose, 85 per cent of a selected group of patients had precepating antibodies. Three precipitating antigen-antibody systems were detected and were shown to be different
