Resumo: Diversas plantas com atividade anti-helmintica vêm sendo utilizadas na medicina veterinária popular. O objetivo deste estudo foi avaliar os efeitos in vitro dos extratos aquosos de Cymbopogon citratus (Capim-santo) e Digitaria insularis (Capim-açu) sobre culturas de larvas de nernatóides gastrintestinaisde caprinos. Seis concentraçoes (mg/ml) do extrato das folhas de Capim-santo (224; 140; 87,5; 54,69; 34,18 e 21,36) e do extrato das folhas de Capim-açu (355,2; 222; 138,75; 86,71; 54,19 e 33,87) foram utilizadas para o tratamento dos cultivos de larvas, realizados em triplicata. Como controle negativo e positivo foram utilizados âgua destilada e doramectina, respectivamente. Os resultados revelaram uma redução superior a 95% do número de larvas da superfamilia Strongyloidea, na concentração de 224 mg/ml para o extrato de Capim-santo e entre 355,2 e 138,75 mg/ml para o extrato de Capim-açu. Estes resultados sugerem que os extratos aquosos das folhas de Capim-santo e Capim-açu são eficazes no tratamento in vitro de nematóides gastrintestinais de caprinos.
Effects of aqueous extracts of Cymbopogon citratus (DC.) Stapf and Digitaria insularis (L.) Fedde leaves on larvae cultures of gastrointestinal nematodes of goats.
Abstract: Several plants with anthelminthic activity have been used in the folk veterinary medicine. The objective of this study was to evaluate in vitro the effects of Cymbopogon citratus (DC.) Stapf and Digitaria insularis (L.) leaves on cultures of gastrintestinal nematodes of goats. Six concentrations (mg/ml) for the aqueous extract of Cymbopogon citratus (224; 140; 87.5; 54.69; 34.18 e 21.36) and for the aqueous extract of Digitaria insularis (355.2; 222; 138.75; 86.71; 54.19 e 33.87) were used to treat larvae cultures. Destilled water and doramectin were used to treat cultures considered to be negative and positive control, respectively. The results revealed a reduction of more than 95% of Strongyloidea larvae on the concentration of 224 mg/ml for the Cymbopogon citratus extract and between the concentrations of 355.2 and 138.75 mg/ml for the Digitaria insularis extract. These suggest that the extracts of C. citratus and D. insularis are effective in vitro on treatment of nematodes gastrointestinais of goats.

The simultaneous occurrence of high levels of exchangeable sodium percentage (ESP) and alkalinity in soils imposes restrictions on plant development and affects physical properties such as porosity, bulk density, permeability, and hydraulic conductivity. Although sodic soils are frequent in the flood plain of the São Lourenço River, northern Pantanal, Brazil, few studies focus on their formation and classification, especially with regard to specific processes and detailed classification into lower categorical levels by the different systems available. The aim of this study was to identify the predominant pedogenetic processes occurring in sodic soils of the flood plain of the São Lourenço River to understand their genesis and assess how taxonomic classification systems contemplate the variations in soil properties. Five profiles were selected in sites with different progressive stages of dissection from erosion (P1, P2, P3, P4, and P5). At each site, a pit was dug for morphological description of the profiles and for collecting samples for chemical, particle size, mineralogical, micromorphological, and chronological analyses. Each profile was classified according to the Soil Taxonomy, World Reference Base (WRB), and Brazilian Soil Classification System (SiBCS/ Sistema Brasileiro de Classificação de Solos). Argilluviation is the predominant process, with a localized and intense ferrolysis action in the E/Bt transition zones in profile P5. Soils showed signs of lithologic discontinuity. This makes it difficult to distinguish how much of the textural gradient is inherited from fluvial sedimentation processes and how much is the result of pedogenetic processes. In the most advanced stage of alteration, P5 had a paler color, thickening of the E horizon, and an abrupt and irregular transition entering the Bt horizon in the form of a ?tongue?. When passing from the most preserved to the most eroded area, ferrolysis becomes more intense in the E/Bt transition, the electrical conductivity values decrease, and the ESP values increase, suggesting the sodification process. Under Soil Taxonomy criteria, P5 was classified as Natraqualf and the other profiles were classified as Natrudalf; under the WRB, however, all profiles were classified as Solonetz. The SiBCS exhibited variation at the Order level, with P5 classified as Planossolo and the others as Luvissolo. Despite an indication of different processes at the Order level, the SiBCS does not yet contemplate the sodic character in the studied Luvissolos. We propose inclusion of the sodic character at the Great Group level, as has already occurred with other SiBCS classes.
