The DFT (B3LYP/6-31 + G) method was used to study the relative stabilities and probable proton transfer in isolated and monohydrated 2,4-dithiothymine molecules in gas phase. The effects of water on relative stabilities and the rate of the proton transfer were analysed. The results indicate that only one tautomer for 2,4-dithiothymine can exist in gas phase.

The results showed that (1) the positive staining of ChAT was obviously observed in the cells of the three kinds of human pituitary adenoma, however, it was lower than that in normal human pituitary gland;(2) ACh had a similar effect on the proliferation of the three kinds of human pituitary adenoma cells. ACh at 0.1~10 μmol/L decreased the [3H]TdR incorporation and the MTT A value in a dose-dependent manner. At the same time, ACh decreased the ratio of S or G2 phase pituitary adenoma cells significantly, but increased the ratio of G1 phase pituitary tumour cells markedly;(3) the effect of acetylcholine on the proliferation of human pituitary adenoma cells was inhibited by atropine, but not by tubocurarine;(4) ACh had no effect on the apoptosis of human pituitary adenoma cells cultured in vitro.

The whole column is placed in a thermostatically controlled heating jacket. A volatile sample is introduced into the column using a syringe, and an unreactive carrier gas, such as nitrogen, passed through it. The components of the sample will be carried along in this mobile phase. However, some of the components will cling more readily to the stationary phase than others, either because they become attached to the solid surface or because they dissolve in the liquid.
