Chinese Journal of Neurology 2000;0(04):-
Objective To clarify the influence of vagus nerve stimulation (VNS) upon glutamate receptor (GluR) and GABA A receptor positive structures in the nucleus tract solitary (NTS) of the kainate (KA) induced epileptic rat. Methods All rats were divided into KA group, vagus nerve stimulation+KA group and the control group. The sections of the caudel medullary oblongata from each rat of every group were collected into 5 sets. The first and second sets of the sections were used to process for immunohistochemical staining by using specific rabbit and mouse antibodies against GluR5 and GABA AR and to observe the changes of GluR5 and GABA AR positive structures in the NTS. The third to fifth sets of the sections were used for control tests and Nissl′s staining. Results (1) In control group, medium density of GluR5 like immunoreactive (GluR5 LI) and GABA A receptor ? chain (GABA AR?) LI neuronal cell bodies, fibers and terminals were observed in the NTS; (2) In KA group, the density of GluR5 LI positive structures were increased, while the density of GABA AR? LI positive structures were decreased; (3) In VNS+KA group, the changes were contrary to the KA group, showing, the density of GluR5 LI positive structures were decreased, and the density of GABA AR? LI positive structures increased. Conclusion Glutamate and GABA A receptors in NTS might play important roles in KA induced epilepsy and in anti epileptic effects of VNS.

A rapid, reliable and sensitive pressurized capillary electrochromatography-Laser induced fluorescence ( pCEC/LIF ) method with trifluoroacetic acid ( TFA ) pre-column derivation for simultaneous determination of four aflatoxin ( AFB1 , AFB2 , AFG1 , AFG2 ) was developed. This method included separation on a capillary column packed with 1. 8μm C18 particles using 0. 05% FA aqueous solution/methanol (55:45, V/V) as mobile phase at a pump flow rate of 0. 05 mL/min when the split ratio was 1:300. Under the optimum conditions including running voltage of 15 kV, excitation wavelength of 375 nm and emission wavelength of 450 nm, the baseline separation of four aflatoxins was achieved within 10 minutes. The limits of detection (LODs) were 0. 02, 0. 016, 0. 008 and 0. 01 μg/L for AFG1, AFB1, AFG2, AFB2(S/N=3), respectively. The linear detection ranges of AFG1 , AFB1 , AFG2 , AFB2 were 0. 1-10, 0. 1-10, 0. 1-3 and 0. 1-3 μg/L with correlation coefficients (R2) of 0. 9999, 1. 0000, 0. 9995 and 0. 9997, respectively. The established method was applied to analyze the peanut butter, and the recoveries of standard addition experiment were between 90 . 0% and 112 . 0% for all analytes ( RSDs=0 . 5%-1 . 9%) .

Journal of International Oncology 2010;37(4):246-248
Inhibitor of growth 2 (INC2 ) is a member of INC family, and cooperates with p53 in regulating cell cycle, apoptosis, and aging. It can also facilitate chromatin remodeling and transcription regulating through histone modifications. Researches suggest that INC2 protein is an important factor in the genesis, metastasis and prognosis of many kinds of tumors. Resent studies indicate that INC2 can not be simply classified as oncogene or tumor suppressor. At present, the function of INC2 in tumorigenesis and tumor development involves interaction with varied molecules, but the mechanisms remain largely unknown, which still require further investigation.
