Abstract: From January to March of 2005 one experiment was developed in a screen house to evaluate the effect of sources and levels of water salinity on emergence and initial development of papaya seedlings cv. Sunrise Solo. A completely randomized experimental design was used and treatments were distributed in a factorial arrangement 3×5, corresponding to three sources (dam water, water salinized with sodium and water salinized with sodium sulfate) and five water saline levels (0.4; 2.0; 4.0; 6.0 e 8.0 dS.m-1) and five replications. At 60 days after seedling emergence the following variables were evaluated: soil electrical conductivity, seedling emergence, plant height, stem diameter and dry mass of shoots and roots. The soil electrical conductivity increased independently of salt source, with more expressiveness for dam water, and all evaluated variables of plant growth were inhibited with water salinity increase. No período, de janeiro a mar o de 2005, foi desenvolvido um experimento em abrigo telado para avaliar o efeito de fontes e níveis de salinidade sobre a emergência e desenvolvimento inicial de plantulas de mam o Havaí cv. Sunrise Solo. Os tratamentos foram distribuídos em delineamento inteiramente casualizado, em esquema fatorial 3×5, correspondente a três fontes (água salina de barragem (AS), água concentrada em cloreto de sódio (NaCl) e água rica em sulfato de sódio (Na2SO4) e cinco níveis de salinidade (0,4; 2,0; 4,0; 6,0 e 8,0 dS m-1) em cinco repeti es. Aos 60 dias após a emergência foram avaliadas as seguintes variáveis: Condutividade elétrica do extrato de satura o do solo (CEes), % de emergência de sementes, altura de plantas, diametro caulinar na altura do colo e biomassa seca de parte aérea e raízes. A CEes do substrato foi elevada, independentemente da fonte utilizada, com maior expressividade para a água de barragem, e as variáveis de crescimento vegetativo avaliadas foram inibidas, independentemente da fonte utilizada, com o incremento da salinidade da água de irriga o.

Abstract: patients with tinnitus and normal hearing constitute an important group, given that findings do not suffer influence of the hearing loss. however, this group is rarely studied, so we do not know whether its clinical characteristics and interference in daily life are the same of those of the patients with tinnitus and hearing loss. aim: to compare tinnitus characteristics and interference in daily life among patients with and without hearing loss. study design: historic cohort. material and method: among 744 tinnitus patients seen at a tinnitus clinic, 55 with normal audiometry were retrospectively evaluated. the control group consisted of 198 patients with tinnitus and hearing loss, following the same protocol. we analyzed the patients' data as well as the tinnitus characteristics and interference in daily life. results: the mean age of the studied group (43.1 ± 13.4 years) was significantly lower than that of the control group (49.9 ± 14.5 years). in both groups, tinnitus was predominant in women, bilateral, single tone and constant, but there were no differences between both groups. the interference in concentration and emotional status (25.5% and 36.4%) was significantly lower in the studied group than that of the control group (46% and 61.6%), but it did not happen in regard to interference over sleep and social life. conclusions: patients with tinnitus and normal hearing showed similar characteristics when compared to those with hearing loss. however, the age of the patients and the interference over concentration and emotional status were significantly lower in this group.

Abstract: purpose: to investigate the influence of partial colectomy associated with hepatectomy on the biodistribution of the 99mtc-phytate, on metabolic parameters, as well as labeling and morphology of red blood cells. methods: wistar rats were distributed into three groups (each with six), nominated as colectomy, colectomy+hepatectomy and sham. in the 30th postoperative day all rats were injected with 99mtc-phytate 0.1ml i.v. (radioactivity 0.66 mbq). after 15 minutes, liver sample was harvested and weighed. percentage radioactivity per gram of tissue (%ati/g) was determined using an automatic gamma-counter. serum ast, alt, alkaline phosphatase and red blood cells labeling were determined. results: the liver %ati/g and red blood cells labeling were lower in colectomy and colectomy+hepatectomy rats than in sham rats (p <0.05), and no difference was detected comparing the colectomy and colectomy+hepatectomy groups. red blood cells morphology did not differ among groups. serum levels of ast, alt and alkaline fosfatase were significantly higher in colectomy+hepatectomy than in colectomy rats (p<0.001). conclusion: hepatectomy associated with colectomy lowered the uptake of radiopharmaceutical in liver and in red blood cells in rats, coinciding with changes in liver enzymatic activity.
