ABSTRACT
The species Heteropterys aphrodisiaca is commonly used as a stimulant by popular medicine in the Cerrado, a savanna-like biome, Brazil. Recent studies have proved its protective effects on testes of animals submitted to treatment using Cyclosporine A, as well as its stimulus effect in increasing testosterone secretion. Therefore, the present study was designed to analyze whether the association of the plant infusion and endurance exercise could potentiate the stimulating effect. The animals were separated into 4 groups: two control (sedentary and trained) receiving water and two treated (sedentary and trained) receiving the plant infusion daily (104mg/day). The proportion of the seminiferous tubule compartment and interstitium was analyzed. Within the seminiferous epithelium, the number of Sertoli and germ cells were counted in order to evaluate whether the treatment would alter the spermatogenic dynamics, analyzing: the spermatogenic yield, the mitotic and meiotic indexes, the total number of germ cells and the Sertoli cell support capacity. Trained and treated animals showed increased spermatogenic yield and spermatogonia mitosis, and no significant differences in apoptotic indexes. Despite the results showing the same pattern regarding yield and mitotic index, the meiotic index was higher in the sedentary/treated group. Therefore, the H. aphrodisiaca infusion increased both the testosterone production and the spermatogonia mitosis, thus increasing the spermatogenic yield.

The Brazilian polyherbal formulation (BPF) is composed by dyes of Eucalyptus globulus Labill, Peltodon radicans Pohl and Schinus terebinthifolius Raddi in alcohol at 13.3° GL. The formulation is popularly used in Paraíba state, Brazil since 1889 and it is used as an antiseptic and anti-inflammatory medicine. The aim of this study was to evaluate the anti-inflammatory property of the polyherbal formulation. For this purpose it was used the12-O-tetradecanoylphorbol 13-acetate (TPA) and capsaicin-induced mouse ear edema and the carrageenan-induced rat paw edema. The BPF at dose of 26 mL/Kg inhibited both 12-O-tetradecanoylphorbol 13-acetate (TPA) and capsaicin-induced ear edema by 49 percent (p < 0.05) and 24 percent (p < 0.01) respectively. Preliminary results on carrageenan-induced rat paw edema demonstrated that oral administration also inhibited the paw edema by approximately 29 percent. The results demonstrate that the Brazilian polyherbal formulation has anti-inflammatory activity and the better dose was the one used by the population.
O medicamento fitoterápico brasileiro - BPF é composto de corantes das plantas Eucalyptus globulus Labill, Peltodon radicans Pohl e Schinus terebinthifolius Raddi em alcool a 13,3° GL. Este medicamento é popularmente usado no estado da Paraíba, Brasil desde 1889 como anti-séptico e antiinflamatório. O objetivo deste estudo foi avaliar a propriedade antiinflamatória deste medicamento fitoterápico. Para tal, foram utilizadas as técnicas de edema de orelha em camundongos induzido por 12-O-tetradecanoilforbol 13-acetato (TPA) ou capsaicina e o edema de pata de rato induzido por carragenina. O BPF na dose de 26 mL/kg inibiu tanto edema de orelha induzido por TPA como por capsaicina a 49 por cento (p < 0.05) e 24 por cento (p < 0.01) respectivamente. Estudos preliminares utilizando a técnica de edema de pata induzido por carragenina demonstraram que a administração oral também inibiu o edema de pata em aproximadamente 29 por cento. Os resultados demonstraram que o medicamento fitoterápico brasileiro (BPF) apresentou propriedades antiinflamatórias e a melhor dose foi aquela que é usada pela população.
