Abstract: Observou-se alta contamina o bacteriana nos explantes de mamoeiro introduzidos in vitro, a partir de plantas matrizes desenvolvidas no campo, independentemente da época do ano em que se realizaram as coletas. O uso de desinfestantes superficiais, como álcool e hipoclorito de sódio, garantiram níveis aceitáveis de controle apenas para fungos, n o para bactérias. A rifampicina, por tratamento de imers o ou introdu o em meio de cultura, controlou satisfatoriamente as contamina es de caráter endofítico, obtendo-se 70% de explantes sadios, sem sinais de fitotoxicidade.

Abstract: Foram estudados os efeitos de três inoculantes microbiológicos na ensilagem do girassol em 16 silos de laboratório confeccionados a partir de baldes plásticos portando válvulas. O girassol, cortado aos 123 dias de crescimento (20,0% de MS e 10,0% de PB), foi homogeneizado e submetido a quatro tratamentos com quatro repeti es: controle, Sil-All (S. faecium, P. acidilactici, L. plantarum, amilase, hemicelulase e celulase), Silobac (L. plantarum, S. faecium e Lactobacillus sp.) e Pioneer 1174 (S. faecium e L. plantarum). Os silos foram abertos após 125 dias para análise da composi o bromatológica e fermenta o. O Pioneer aumentou a concentra o de carboidratos solúveis, a concentra o de etanol e o poder tamp o, diminuiu a concentra o de nitrogênio amoniacal, a concentra o de ácido acético e o pH, em rela o ao grupo controle. Este produto também aumentou a concentra o de amido em rela o ao grupo controle, enquanto o Sil-All diminuiu. N o foram observados efeitos dos inoculantes sobre a MS, PB, NIDA, FDN, FDA, lignina, digestibilidade in vitro da matéria seca, perdas de matéria seca, estabilidade aeróbia ou sobre as concentra es dos ácidos propi nico, butírico e lático.

Abstract: an evolutive study of the "case-control" type was carried out in an endemic area of chagas' disease in minas gerais state, brazil, using two cross-section evaluations with an interval of ten years between them (1974-1984). patients were paired for sex and age. in the first cross-section study 264 pairs one with a positive serology and the other with a negative serology for t. cruzi antibodies were included. in the second evaluation, ten years later, 235 patients among those with previous positive serology and 216 with negative serology were located, but only 110 pairs could be recomposed and reexamined (clinical examination, ecg and rx of the heart and esophagus). the incidence of chagasic cardiopathy in the cases with positive serology but previously assymptomatic was 38.3% during the ten year period. on the other hand there was a deterioration in 24% of the patients with chagasic cardiopathy since the first examination. considering all clinical forms of the disease in 34.5% of the patients the clinical situation deteriorated, in 57.3% there was no change and in 8.2% the situation improved. the general mortality in the period was 23% in the chagasic group and 10.6% in the control group, but the lethality by cardiopathy was 17% in chagasic group and only 23.3% in the control group. the mortality was twice as high in males than in females, mainly in the age group from 30 to 59 years.

Abstract: water and nutrient availability in the soil at suitable times and in adequate amounts, as related to edaphic and climatic conditions, are undeniably relevant for crop yields. the objective of this work was to evaluate the actual evapotranspiration of an orange plantation, analyze its variability and verify the influence of the soil water loss on crop productivity. the experiment was carried out in piracicaba county (sp), brazil, on an oxisol. the actual evapotranspiration was evaluated by a soil water balance model with 40 experimental points corresponding to 40 plants of two adjacent plant rows with 20 plants each. the orange trees, grown in a 7 x 4 m spacing (7 m between rows and 4 m between plants), were 11 -year-old. in each point, an aluminium tube was inserted at the canopy projection (2 m from the stem) of each one of the 40 plants in the rows down to a depth of 1.2 m to provide access to a neutron probe. three tensiometers were placed at depths of 1.0, 1.1 and 1.2 m. water storage in the 0.0-1.1 m soil layer was determined based on the weekly neutron probe readings. rainfall, measured with an automated rain gauger, was normal for the study period. internal drainage and capillary rise were estimated by the darcy-buckingham equation based on daily readings of the three tensiometers and on the hydraulic conductivity, determined at the control depth (1.1 m) as a function of matric potential through the instantaneous profile method. irrigation and run-offs were negligible and the actual crop evapotranspiration was calculated by the difference between soil water storage and the sum of the other evaluated processes. the balance was estimated for 14 periods during the annual cycle of the orange crop. in these 14 monitoring periods, the actual evapotranspiration was analyzed by means of descriptive and exploratory statistical methods; mean variation coefficient of these 14 periods was 16%. the annual actual evapotranspiration was 1.271 mm and daily mean values ranged
