| Este trabalho foi desenvolvido para se encontrar um método de controle químico do arroz. Os experimentos foram realizados na Região do Baixo Vale do Itajaí, nos anos de 1978 e 1980. Os herbicidas 2,4-D amina, benthiocarb, oxadiazon, metolachlor e alachlor, quando aplicados em quadros inundados e, com 13 e 15 dias de antecedência à semeadura do aroz cultivado, apresentaram controle de arroz vermelho acima de 75% e controle total das plantas daninhas comuns da área. A população do arroz cultivado não foi afetada com a aplicação desses herbicidas. As produções alcançadas, com a aplicação desses herbicidas foi variável e dependia do nível de infestação de arroz vermelho e das outras plantas daninhas. |

| We demonstrated that 4 mM butyrate induces apoptosis in murine peritoneal macrophages in a dose- and time-dependent manner as indicated by studies of cell viability, flow cytometric analysis of annexin-V binding, DNA ladder pattern and the determination of hypodiploid DNA content. The activity of caspase-3 was enhanced during macrophage apoptosis induced by butyrate and the caspase inhibitor z-VAD-FMK (100 µM) inhibited the butyrate effect, indicating the major role of the caspase cascade in the process. The levels of butyrate-induced apoptosis in macrophages were enhanced by co-treatment with 1 µg/ml bacterial lipopolysaccharide (LPS). However, our data indicate that apoptosis induced by butyrate and LPS involves different mechanisms. Thus, LPS-induced... |

| Lactobacillus delbrueckii UFV-H2b20 has been shown to increase clearance of bacteria injected into the blood of germ-free mice. Moreover, it induces the production of type 1 cytokines by human peripheral mononuclear cells. The objective of the present study was to investigate the production of inflammatory cytokines [interleukin-12 (IL-12 p40), tumor necrosis factor-α (TNF-α), and interferon-γ (IFN-γ)] triggered in vitro by live, heat-killed or lysozyme-treated L. delbrueckii UFV-H2b20 and in vivo by a live preparation. Germ-free, L. delbrueckii-monoassociated and lipopolysaccharide (LPS)-resistant C3H/HeJ mice were used as experimental models. UFV-H2b20 induced the production of IL-12 p40 and TNF-α by peritoneal cells and IFN-γ by spleen cells from... |
