[Primary Mechanisms of CD34CD38--KG1a Leukemia Stem Cells Apoptosis Induced by FA-2-b-β Extracted from Qinba Selenium- Mushroo].

Objective: To investigate the apoptosis of CD34CD38-KG1a leukemia stem cells induced by Qinba selenium-mushroom extract(FA-2-b-β), and its related mechanism.

Methods: CD34CD38--KG1a cells were isolated from KG1a cell line by magnetic activated cell sorting. The proliferation ability of KG1a stem cells treatd by various concentration of FA-2-b-β(1.

Central administration of neuronostatin induces antinociception in mice.

Neuronostatin, a recently discovered endogenous bioactive peptide, was encoded by pro-mRNA of somatostatin that contributes to modulation of nociception. However, nociceptive effect of neuronostatin is still not fully known. The aim of this study was to evaluate effect of neuronostatin on nociception and elucidate its possible mechanism of action.

The antidepressant-like effect of human opiorphin via opioid-dependent pathways in mice.

In the present study, we investigated the antidepressive activity of opiorphin with central administration in the forced swim test in mice. Intracerebroventricular (i.c.
