Reflexiona sobre el uso de las redes sociales en la gestión pública, tomando como referencia la gestión que realizó la SUTRAN en sus cuentas de Facebook y Twitter en el año 2017. Describe la gestión de las redes sociales de dicha insitución desde la generación de contenidos, la elaboración de mensajes y la interacción. Analiza el uso de las redes sociales como complemento de la comunicación institucional de la SUTRAN.

The immunomodulatory activity was studied in function of the production of γ−IFN induced by the methanolic extracts (ME) of the white, black, red and purple ecotypes of Lepidium peruvianum, Chacón (at present Lepidium meyenii Walp.) maca, on cultures of human T lymphocytes obtained of periferic blood. After cultivating the lymphocytes with the respective ME of maca during 14 hours, only the ME of the purple ecotype induced the significant production of IFN−γ by Elispot quantified. The methanolic extract of the purple ecotype of maca possesses important immunostimulatory properties triggering the activation of the human T lymphocytes.

The macrophages play an important role in the innate and adaptative response. Upon appropriate activation, macrophages released a variety of cytotoxic mediators like the Nitric Oxide (NO). The objective was to evaluate the production of NO for murine peritoneal macrophages cultivated with methanol extracts (ME) of different ecotypes of Lepidium peruvianum Chacón (at present Lepidium meyenii Walp.) red, black, purple and white. The ME was prepared using maca powdered macerated in methanol (1:2) during 10 days. Peritoneal macrophages were obtained of mice 3 days after having injected them 1 ml of thioglycolate broth; they were cultivated for triplicate during 18 hrs at 37 °C in RPMI 1640 medium supplemented with 10% fetal calf serum. The dose of ME was of 800 μg/ml for ecotype, were considered controls without ME. The production of NO was assayed by nitrite accumulation in the supernata...

The classic treatment of the cutaneous leishmaniosis consists on the injection of 15-20 ampoule of Glucantine what causes serious secondary effects. This fact justifies the search of new medications what motivated the present investigation. The objective was to evaluate the leishmanicidal activity of the methanolic extracts (ME) of the white, red, purple and black ecotypes of Lepidium peruvianum Chacón (at present Lepidium meyenii Walp.) about the growth of Leishmania braziliensis peruviana in vitro. The promastigotes reached the logarithmic phase to the fifth day of cultivation at 27 ºC in the two-phase Columbia medium with 15% of defibrinated sheep blood and they faced, for separate, with the ME to concentrations of 50, 100, 200 and 400 μg/ml. The recounts were made daily with camera Neubauer. The maximum decrease of promastigotes (17.41% of viability) took place to the second day f...
