Antiedematogenic effects of the polar fractions of Persea cordata Mez. (Lauraceae) on microvascular extravasation in rat skin.

Ethnopharmacological Relevance: Persea cordata Mez. (Lauraceae) is a medicinal plant used in veterinary ethnopharmacology, which is a popular medicine used as an anti-inflammatory and healing agent, mainly on animal skin diseases, characterized by cutaneous open wounds, in South Brazil.

Aim Of This Study: The purpose of this study was to investigate a possible antiedematogenic effect of ethyl acetate (EtAc) and butanol (BuOH) polar fractions of Persea cordata on Evans blue dye leakage induced by pro-inflammatory agents in rat skin.

Evaluation of multidrug resistance in 46 newly diagnosed patients with acute leukemia.

Objectives: The aim of the present study was to assess the expression profile of multidrug resistance (MDR)-related proteins ABCB1, ABCC1 and LRP in 46 patients with acute leukemia (AL).

Methods: The levels of MDR gene mRNA expression and protein expression at diagnosis were analyzed by semi-quantitative PCR and flow cytometry, respectively.

Results: In the adult group, higher expression levels of abcc1 gene were associated with older age and lower levels of lactate dehydrogenase (LDH).
