RENAL HISTOPATHOLOGICAL FINDINGS IN DOGS WITH VISCERAL LEISHMANIASIS

Visceral leishmaniasis affects various organs including the kidneys; which can lead to renal failure and death. In order to verify this renal involvement, material was evaluated from 100 dogs naturally infected and with serological diagnosis of canine visceral leishmaniasis (CVL). Inflammatory changes were present in 25.3% of the tubules, in 67.0% of interstitium and in 52.0% of glomeruli. There was no significant difference (p > 0.05) between the presence of glomerulonephritis in symptomatic and oligosymptomatic dogs. The membranous and membranoproliferative glomerulonephritis were the most frequent, both with 18.0% frequency, followed by focal segmental glomerulosclerosis with 14.0%. Changes such as cylindruria, tubular and fibrosis hypertrophy, periglomerular inflammatory infiltrate, and multifocal and diffuse peritubular inflammatory infiltrate were observed. The findings are consistent with those of other authors indicating that renal involvement is common in CVL and the standards of membranous and membranoploriferative glomerulonephritis, as well as the tubulointerstitial involvement, are frequent.

EFEITO LARVICIDA DE RICINUS COMMUNIS L

Effective larvicides in low concentrations, and is easily obtained in the region, are intensely sought by public health agencies. Therefore, the aim of this study was to evaluate the potential larvicide leaf extract and oil of the fruit of Ricinus communis on the larvae of Aedes aegypti. The results showed that seed and leaf extracts promoted total mortality of the larvae, and this effect is independent of concentration. Therefore, indicates the use of R. communis in endemic regions to control larvae.

CULTIVE TISSUE OF SALVIA HISPANICA L

Chia (Salvia hispanica L.) is an annual herbaceous plant native to Mexico in pre-Columbian times was used a lot with food and medicinal purpose, but during the process of domestication suffered habitat loss due to degradation of natural resources. It has high contente of omega-6 and omega-3, potent antioxidants, protein, dietary fiber, α-linoleic, widely used in weight reduction treatments, and reduction of cholesterol and its price is always high (100 g seed costs on average £ 25.00). The objective was to evaluate the production of seedlings of S. hispanica from embryos in culture media with and without sucrose. Held at 120 seed disinfection detergent Tween 80 for 2 minutes soaking in 1% sodium hypochlorite for 5 minutes in 70% ethanol for 2 min followed by rinsing three times with sterile distilled water. After this procedure, the seeds were placed in glass vials with 5 mL of liquid MS medium plus 30 g L-1 sucrose 100 mg L-inositol 1 pH adjusted to 5.8 without and without phytoregulator agar. Was used as control MS medium without sucrose and without agar. The cultures were kept in a growth chamber at 25 ± 2 ° C under a photoperiod of 16 hours. Each vial contained 30 seeds with 4 replications. We evaluated the germination and early growth of the seedling root and hypocotyl. 60 seedlings per treatment were used for evaluation of measures with a millimeter ruler on the length of the shoot and root. Germination was always higher in cultures with sucrose. Plantlets from 14 days had higher growth of shoots and roots in MS medium with sucrose. Sucrose directly affects seedling development of chia and may impair normal growth and promote somaclonal variation.

Estratégias de marketing rural: assentamento conquista

O desafio principal para se programar as estrategias do marketing rural em uma comunidade de assentados nos impeliu a exploracao desse estudo com finalidade de verificar o ponto forte de sobrevivencia da populacao em tela, onde e em que nicho de mercado melhor se fazem adequadas quanto aos distintos conhecimentos empiricos, existentes e latentes. Buscamos visualiza-los quanto a sustentabilidade, via quatro vertentes: ambiental, economica, social e politica. Detectou-se a inexistencia de um processo operacional padronizado.

Bioremediation and remediation with acid residual fluid

The aim of this study was to evaluate the feasibility of using bioremediation and F. moliniforme in remediation of compounds made from plastics and other polymers using waste pollutants. The survival analyzes for survival / growth resistance and pollutants in the concrete for 30 days was observed. We evaluated the size of the colonies in battery fluid (pH = 0.1) and weekly reviews of pH in three 1000 mL volumetric flasks, having in each 133 mL of battery + 100 mg of Fusarium moliniforme. To review the development and formation of colonies of microorganisms miners, we used 320g samples distributed in three trays concrete material. And was inserted solution of green algae free and Fusarium moliniforme life. With mixing the solution with a battery for inoculation of nutrient Fusarium moliniforme in an alkaline environment (pH between 10 and 14) means. Observed the growth of colonies and changing an pHs for a neutral medium (pH 7.0): 78 colonies. In three days sleeve dilution initiated and completed processing within 30 days. This process occurred with a combination of solution and battery residual crushed lime construction and promoted the transformation of the solid phase in the liquid phase in only 30 days. After 2 days s solution was neutralized (pH 7) and thus remaining constant. The battery solution can be neutralized with the addition of carbonates for remediation. The combination of battery solution more carbonates digested the solid state of natural rubber surgical glove can be reused by the industry to produce new products. Fusarium moliniforme biorremediador should be used as the treatment of contaminated soils ex situ, bioadition and bioaugmentation because this fungus neutralized acidic pH of contaminated soils with concrete residue.
