    A retrospective study done by means of the revision of 416 medical records from cutaneous leishmaniasis patients, treated exclusively with pentavalent antimony (Glucantime® and Ulamina) at the Centre of Parasitological Research “Jose Witremundo Torrealba”, at the University of Los Andes, in Trujillo, Venezuela, during a period between June 1989 and June 2002, with the objective of determinates the tolerability of these compounds in terms of local adverse reactions, systemic and of cutaneous hypersensibility. Additionally, some physical-chemical characteristics were quantified in lots of both of the pharmaceutics used during the appointed period with the aim of justify the observed differences. A local cutaneous reaction was presented (induration, edema, eritheme and itch) in 13% of 166 patients treated with Glucantime® and in 7% of 250 treated with Ulamina, the systemic reactions found were hypertension, tachycardia, disnea, hepatitis, fever, headache, dizziness, asthenia and systemic allergic reaction in 3% of (Glucantime® treated patients and in 2% of the Ulamina ones. The positiveness to the cutaneous hypersensibility test was significantly higher with Ulamina. The loss of Ulamina showed a lower concentration of total and pentavalent antimony, chlorates, density and similarity, the lasts three of statistical significance

    Recuperación de huevos de Ascaris lumbricoides del follaje de hortalizas intencionalmente contaminadas
    (2007) J. V. Scorza; Migdalys Vilchez
    Hasta el presente, ninguna de tales tecnicas ha sido evaluada en su sensibilidad y rendimiento para detectar y cuantificar huevos de parasitos en hortalizas contaminadas. En este trabajo nos proponemos evaluar una tecnica de lavado y sedimentacion de hojas frescas de hortalizas contaminadas experimentalmente con huevos de Ascaris lumbricoides, parasito prevaleciente en 29% de 100.000 personas examinadas coproscopicamente entre 1989 y 1992, que son residentes en cien localidades de las veintitres entidades federales de Venezuela, incluyendo diecisiete en los estados andinos, productores de hortalizas (Morales et al., 1999).
