ABSTRACT
Objective To investigate gallic acid-derived chemical constituents of Choerospondias axillaries (Roxb.) Burtt. et Hill., and evaluate their in vitro anti-tumor, anti-hypoxia and anti-bacteria activities. Methods The aimed chemical constituents were isolated by various chromatographic means, and their structures were identified by physicochemical and spectroscopic data. MTT method was employed to evaluate anti-tumor and anti-hypoxia activities. Antibacterial activities were tested by paper disc method. Results Seven compounds 1-7 were isolated from the stem barks of Choerospondias axillaries (Roxb.) Burtt. et Hill. and identified as gallic acid(1), gallic acid ethyl ether(2), 1-O-galloyl-β-D-glucose(3), 1,6-di-O-galloyl-β-D-glucose(4), 1,4-di-O-galloyl-β-D-glucose(5), 1,4,6-tri-O-galloyl-β-D-glucose(6), and 1,3,4,6-tetra-O-galloyl-β-D-glucose(7). Compounds 1, 2 and 4-6 significantly inhibited K562 cells with the IC50 values of 2.9, 14.6, 39.1, 40.2, 41.2 μg/ml, respectively, and 3 and 7 also showed a slight inhibition of the K562 cells with the inhibition rate of 20.8% and 30.1% at 100 μg/ml respectively. Compounds 1-7 showed protective effects on anoxia-induced injury in cultured ECV304 and PC12 cells at the concentrations showing no significant cytotoxicity, and 5-7 also showed an antibacterial effect on Staphylococcus aureus ATCC6538 to a certain extent. Conclusion Compounds 2-7 were isolated from the genus Choerospondias for the first time. It was the first time to report 1-7 as anti-tumor and anti-hypoxia constituents of Choerospondias axillaries, and the anti-hypoxia activity for 1-7 was also recorded for the first time in the present study.

ABSTRACT
Desde 1990 utilizamos durante la disección axilar en los casos de cáncer de mama, una maniobra que nos permite: identificar mejor la vena axilar en su porción externa, finalizar la disección del músculo dorsal ancho (m. latissimus dorsi), medir el grosor del tejido axilar a disecar y descartar la presencia del arco vascular de Lange, anomalía que puede presentarse en un 5 por ciento a 6 por ciento de los casos. Consideramos que este procedimiento ayuda a simplificar la disección axilar durante el acto quirúrgico. No hemos conseguido publicaciones que describan esta maniobra y hemos decidido hacer esta comunicación.
Since 1990 we used during axillaries dissection in cases of breast cancer, a maneuver that allows us; identify better the axillaries vein in the external portion, finalize the dissection of wide dorsal muscle (M. latissimus dorsi), measure the thickness of the axillary weaves to dissect and discard the presence of the vascular Lange arc, anomaly that can appear in 5 percent to 6 percent of the cases. We considered that this procedure helps to simplify the axillaries dissection during surgical act. We have not obtained publications that describe this maneuver and have decided to make this communication.

El tratamiento conservador de la glándula mamaria ha permitido mantener el éxito oncológico en el tratamiento de cáncer invasor, sin sacrificar estética y funcionalidad. Desde marzo de 1980 en la Unidad de Mastología del Centro Clínico de Maternidad Leopoldo Aguerrevere se siguieron pacientes con cáncer de mama T1 y T2, no mayor de 3 cm, 543 pacientes se dividieron en: primer grupo 295 pacientes desde mayo 1980 al 1998, a los cuales se les realizó mastectomía parcial oncológica con disección axilar de los niveles I y II y un segundo grupo desde mayo 1998-diciembre 2004, a los cuales además de la mastectomía se les realizó identificación del ganglio centinela por técnica combinada de tecnecio 99 y azul patente, y disección axilar cuando este último fue positivo. El promedio de edad fue de 53,13 años, estadio clínico más frecuente fue I, el tamaño tumoral similar en ambos grupos de estudio. Sobrevida global para el grupo total fue 85,5% a los 5 años y 68,5% a los 10. La libre de enfermedad de 83,6% a los 5 años y 63,2% a los 10 años.
The conservative treatment of the mammary gland has allowed support the success in the treatment of invasive cancer, without sacrificing the esthetic and functionality of the organ. Since March 1980 at the mastology unit Clinica Leopoldo Aguerrevere we followed patients with breast cancer T1 and T2, no bigger than 3 cm. 543 patients were divide in a first group of 295 patients from May, 1980 to December 1998, to which a partial oncological mastectomy was made by axillaries dissection of the levels I and II, and a second group from May, 1998 to December 2004 with partial mastectomy and identification of the sentinel lymph node biopsy using a combined technique of tecnetium 99 and clear blue, and axillaries dissection when the sentinel node was positive. The average of age was 53.13 years and the most frequent clinical stage was I, being the tumor similar size in the both groups of study. The global survival of the total group was 85.5% at 5 years and 68.5% at 10 years. Free survival disease was 83.6% at the 5 years and 63.2% at 10 years.

Aim To study the molecular basis of protection on myocardial ischemic injuries of total flavones of choerospondias axiaris fructus(TFC). Methods The microarray analysis for the protein expression in myocardium provide a strong tool to explore the key protein candidates involved in the pathogenesis of ischemic injury.Surface enhanced laser desorption/ionization(SELDI) mass spectrometry with protein chip IMAC3,SAX2 and NP20 was used to compare the differentially expressed protein in TFC-treated and untreated ischemic myocardium in rats and the results were analysized with Proteinchip Software 3.0.2.Results Seven differentially expressed proteins were indentified in TFC treated myocardium.These differential effects correlated with the expression of five downregulated proteins and two upregulated proteins,and four of them were discovered on the IMAC3 chip and one of them was discovered on the SAX2 chip.Conclusions The myocardial protection of TFC may be mediated by the differential expression of these proteins which could be the key protein candidates for further investigation.
