实验参考方法

Cell experiment:

The HeLa cell line is grown in DMEM media supplemented with 10% FBS and 1% 1003 Pen Strep. Cells are cultured under a controlled atmosphere (37°C, 5% CO2). Glass bottom dishes are used for cell culture due to confocal scanning requirements. Cells are treated with RT-AM (1 μM with 1% DMSO in DMEM) for 10-15 min before imaging. Confocal images are acquired with 405 nm laser/418–495 nm filter and 488 nm laser/499–615 nm filter. All the microscope settings are kept consistent in each[1].

产品描述

RT-AM is a pro-drug real thiol. Real Thiol is a reversible reaction-based fluorescent probe which can quantitatively monitor the real-time glutathione dynamics in living cells.

To enhance the cell permeability of Real Thiol, the carboxylic acid groups is converted to acetoxymethyl (AM) esters, which are readily hydrolysed by esterases to regenerate Real Thiol inside cells. For cells treated with the RT-AM, real-time ratiometric images of the rapid changes of intracellular GSH concentrations in single cells can be generated by dividing the fluorescence intensity values for the 405 nm channel by the 488 nm channel at each corresponding pixel[1].

[Effects of astragalus membranaceus on TH cell subset function in children with recurrent tonsillitis]

Zhongguo Dang Dai Er Ke Za Zhi 2006 Oct;8(5):376-8.PMID:17052394doi

Objective: To observe the TH cell subset function in children with recurrent tonsillitis (RT) at the remission stage and to study the effects of astragalus membranacus (AM) on TH cell subset function. Methods: The peripheral blood mononuclear cells (PBMC) from 27 children with RT at the remission stage were stimulated with either phytohemagalutinin (PHA) (RT-PHA group) or PHA together with AM (RT-AM group) and were then cultured in vitro for 48 hrs. The samples from 21 healthy children stimulated with PHA were used as the Control group. The levels of interferon-gamma (IFN-gamma) and interleukin-4 (IL-4) in the supernatants of PBMC were detected using ELISA. Results: The IFN-gamma level and the ratio of IFN-gamma/IL-4 in the RT-PHA group were statistically lower than those in the Control group (P < 0.01). The level of IFN-gamma and the ratio of IFN-gamma/IL-4 in the RT-AM group were markedly higher than those in the RT-PHA group (P < 0.01), but were significantly lower than those in the Control group (P < 0.05). There were no differences in the IL-4 level among the three groups. Conclusions: TH1 cell subset dysfunction may exit in RT children at the remission stage, suggesting that TH1 cell subset dysfunction plays an important role in the pathogenesis of RT. AM can improve TH1 cell subset function and therefore shows an important significance in treating RT.
