The zona pellucida glycoconjugate content of several marsupial species was investigated using differential lectin histochemistry. Ovaries from fat-tailed dunnarts, a southern brown bandicoot, grey short-tailed opossums, brushtail possums, ringtail possums, koalas and eastern grey kangaroos were fixed, embedded in paraffin wax, sectioned and stained with ten fluorescein isothiocyanate-conjugated lectins. Sections were also incubated with either neuraminidase or saponified, respectively, before incubation with the lectins to identify saccharide residues masked by sialic acids or O-acetyl groups on sialic acids. The zonae pellucidae surrounding the oocytes of the marsupials demonstrated interspecific variation in glycoconjugate content, with mannose-containing glycoconjugates exhibiting the greatest variation. Some of the zona pellucida glycoconjugates of all species, except those of the opossums, were masked by sialic acid with an increase in fluorescence with lectins from Arachis hypogea (PNA), and Glycine max (SBA), after desialylation. The disaccharide beta-galactose(1-4)N-acetyl-D-glucosamine appeared to be conformationally masked by O-acetyl groups of sialic acids in the zonae pellucidae of all species, with an increase in fluorescence with the lectin from Erythrina cristagalli (ECA), after saponification. Similar intensity and localization of beta-(1-4)-N-acetyl-D-glucosamine, as shown by staining of the lectin from Triticum vulgaris (WGA), to the inner and outer regions of the zona pellucida, were found to those reported in eutherian species. WGA fluorescence became uniform throughout the zonae pellucidae after saponification, indicating differential O-acetylation of sialic acids on the internal compartment of the zonae pellucidae.

ABSTRACTPeanut shell (PS) infusion has been shown to be antithrombocytopenia, but there has been no research on safety standards. This study aims to identify the symptoms of toxic effects, the potency of toxicity and histopathology of liver male Balb/C mice after a single dose of PS infusion. This research uses randomized matched posttest only control group design. Twenty five mice were divided into 5 orally dosage groups, ie, PS infusion with a dose of 0,026; 0.052; 0.104; 0.208 g/20gBW; and negative control of CMC Na 0.5%. The observation period is for 14 days. The results showed that single dose of PS infusion had a pseudo LD50 value ie > 0.208g/20gBW which was practically non toxic. Symptoms to watch out for the BW infusion were passive behavior, bradycnea, hair color change, hair loss, and weight loss at doses of 3 and 4. It is unclear whether liver damage ie inflammation, necrosis, and albuminous degeneration caused by PS infusion or other causes.keywords: acute toxicity, infusion, peanut shell

O amendoinzeiro responde positivamente quanto à produção de grãos quando associado a fungos micorrízicos arbusculares (FMA), porém é necessário verificar sua dependência para diferentes espécies em diferentes níveis de fósforo (P). Este trabalho teve por objetivo determinar a dependência micorrízica de Arachis hypogea L. cv. Runner IAC 886 sob diferentes concentrações de P, e avaliar o desenvolvimento do hospedeiro e do endófito após a colonização. O experimento foi conduzido em casa de vegetação, em delineamento inteiramente casualizado, com duas espécies de FMA (Gigaspora rosea e Glomus clarum) e um controle não inoculado, combinados com quatro doses de P aplicados no solo: 0, 75, 150 e 250 mg kg-1. Após 50 dias da germinação do amendoim, foram avaliados a matéria seca (MS), a colonização radicular, o número de esporos no solo, a dependência micorrízica e a disponibilidade de P. Verificou-se que as plantas de amendoim apresentaram dependência micorrízica à inoculação com a espécie G. rosea nos tratamentos com baixo suprimento de P e com G. clarum somente na ausência do nutriente. A inoculação com G. rosea proporcionou maior produção de MS total na dose de 75 mg kg-1 de P (7,2 g por planta), sendo que houve aumento no acúmulo de P na parte aérea até na maior dose de 250 mg kg-1 de P. Já a espécie G. clarum apesar de ter proporcionado maiores números de esporos e colonização radicular, apresentou o menor crescimento das plantas e menor eficiência na utilização de P pela parte aérea.

<p>The objectives of this study is to evaluate the effect of mycorrhizae propagules and rhizobium on the growth on legume plants (Arachis hypogea) in marginal land. The experiment was conducted in Nguter village Lumajang, East Java. The results showed that mycorrhizae propagules stimulated rhizobium and plant growth by increasing plant height, dry weight and nodule weight. This results implied that mycorrhizae propagules stimulated and rhizobium were advantageous promoting growth at marginal lands.</p><p><br /><strong>Keywords</strong>: Mycorhiza propagul, Rhizobium, legume and Marginal land</p>
