Glucose-6-Phosphatase (G6Pase) was regarded as a marker enzyme of the endoplasmic reticulum in a number of different cells. The purpose of this report is to study the localization of G6Pase activity in the rat left ventricular myocardial cells. G6Pase activity was found in the lumen of the nuclear envelope, the sarcoplasmic reticulum(SR) and the subsarcolemmal cisterns. The SR tubules between the adjacent myofibrils displayed characteristic distribution on their longitudinal profiles, as a curtain-like network, the tubules appeared to be tight network facing A-band, whereas tubules formed large polygonal meshes facing I-band. It is thought that the SR tubules facing A- and I-bands, respectively, represented an adaptation of SR to the selective shortening of the myofibrils at the I-band during contraction.

Left ventricular myocardial hypertrophy was produced in the rats by ligation of the abdominal aorta below the diaphragm for seven weeks.Ultrastructurally, it was observed that the nucleus and nucleolus were enlarged, and the density of the chromatin of the hypertrophied myocardial cells was decreased. Free ribosomes and endoplasmic reticulum were increased. Golgi apparatus was well developed and was increased in number.Cytochemically, G6Pase activity was localized in the lumen of the sarcoplasmic reticulum, nuclear envelope and subsarcolemmal cisterns, and it was also positive in the regenerative rough endoplasmic reticulum. TPPase activity appeared in the Golgi apparatus, and it was especially prominent in the Golgi apparatus of the hypertrophied cells.These findings suggest that the protein synthetic activity was increased in the hypertrophied myocardial cells.

To develop a safe and effective new generation vaccine for IRKV-THChina12 prevention, we constructed a non-replicative recombinant human adenovirus carrying the IRKV-THChina12 G gene, named as rAd5-IRKV-G. The IRKV-THChina12 G protein expressed by the recombinant human adenovirus in 293AD cells was detected by western blot and indirect immunofluorescence test. To evaluate the immunogenicity of the recombinant, mice were immunized with rAd5-IRKV-G by intramuscular (i. m.) or intraperitoneal (i. p.) route and with non-exogenous gene expressing wild type adenovirus wt-rAd5 as a control. Results showed that the rAd5-IRKV-G could induce continuous and statistically significant (P ≤ 0.05) anti-IRKV neutralizing antibody (NA) production in immunized mice by i. m. or i. p. route. In particular, no significant difference (P > 0.05) of the NA titers between the two administration routes were observed, that provides an alternative choice for animal immunization method in the future application.

Aim To observe the influence of hydrogen sulfide on L-arginine/nitric oxide synthase(NOS)/NO pathway,explore the interaction between H_2S and NO as cardiovascular regulatory gasotransmitters.Methods Aortic thin slices in vitro were administrated with NaHS(10~(-7) mol?L~(-1)～10~(-4) mol?L~(-1)),a donor of H_2S,and incubated for 4 hours,or 50 ?mol?L~(-1) NaHS and incubated for 2 h,4 h and 6 h,respectively.The nitrite production Was measured with greiss assay;NOS activity and L-arginine transportation,with isotope tracer method;the eNOS and CAT1-A gene expression,with RT-PCR.Results After being given with NaHS(50 ?mol?L~(-1)) one time,and incubating for 2 h,the nitrite production decreased by 62%,NOS activity reduced by 48% and L-arginine transport decreased by 50%.After incubation for 6 h,the nitrite production further was inhibited by 19%(P0.05).NaHS(10~(-7) mol?L~(-1)～10~(-4) mol?L~(-1)) inhibited the L-arginine/NOS/NO pathway in a dose-dependent manner,and IC_(50) was 0.499,3.198 and 3.927 ?mol?L~(-1)(P

Objective To compare the effects of fentanyl,sufentanil and remifentanil on the immune function of dendritic cells in human umbilical cord blood.Methods Human umbilical cord blood mononuclear cells were obtained by density gradient centrifugation and seeded in 24-well plates with a density of 1 × 106/ml (2ml/hole).The cells were randomly divided into 7 groups (n =15 each):control group (group C),fentanyl 1.0 ng/ml group (group F1),fentanyl 5.0 ng/ml group (group F5),sufentanil 0.1 ng/ml group (group S1),sufentanil 0.5 ng/ml group (group S5),remifentanil 1.0 ng/ml group (group R1),and remifentanil 5.0 ng/ml group (group R5).The cells were incubated for 10 days in serum-free culture medium containing 50 ng/ml recombinant human granulocyte colony stimulating factor,10 ng/ml recombinant human interleukin-4 or the corresponding concentration of fentanyl,sufentanil or remifentanil,and then 50 ng/ml recombinant human tumor necrosis factor alpha was added to the culture medium and the cells were incubated for another 4 days in the seven groups.Three holes in each group were chosen and the cell morphology was examined with inverted microscope.Six holes in each group were chosen for determination of the concentration of IL-12 in the supernatant and expression of CD80/CD86.Six holes in each group were chosen for measurement of the cell viability.Results Compared with group C,the concentration of IL-12 and cell viability were significantly decreased and the expression of CD80/CD86 was down-regulated in groups F5,S1,S5,R1 and R5 (P ＜ 0.05).The concentration of IL-12,cell viability and expression of CD80/CD86 were significantly lower in groups S1 and R1 than in group F1 (P ＜ 0.05).Compared with group F5,the concentration of IL-12 was significantly decreased in group S5,and the concentration of IL-12 and cell viability were significantly decreased and the expression of CD80/CD86 was down-regulated in group R5 (P ＜ 0.05).The concentration of IL-12 and cell viability were significantly lower in group R1 than in group S1 (P ＜ 0.05).The concentration of IL-12,cell viability and expression of CD80/CD86 were significantly lower in group R5 than in group S5 (P ＜ 0.05).Conclusion Remifentanil has stronger inhibitory effect on the immunological function of dendritic cells in human umbilical cord blood than sufentanil,and the inhibitory effect of sufentanil is stronger than that of fentanyl.

Thirty mothers of four dadys later after delivery with agalactia, whose babies needed additional milk over one third of physiological needs, or agalorrhea were chosen to take 125 g of MUYINGLE divided into 3 parts a day for observing its lactigenous effect, and thirty other agalactous mothers, who might chose any kind of traditional Chinese lactagogue foods to eat, as control group. Those subjects whose babie's additional milk was less than one fourth or half of physiolgical needs for agalactia or agalorrhea respectively after four days with MUYINGLE were effectual. The results showed that the lactagogue efficacious rate of MUYINGLE and control group were 86. 7% and 33. 3%, respectively. The lactagogue effects were significant difference between the two groups (P

Objective:To study the inhibitory effect of deoxyschizandrin on the growth of brain glioma C6 cells, and to explore its mechanism.Methods:The rat glioma C6 cells were cultured and divided into control group,50, 100,and 200 mg·L-1 deoxyschizandrin groups.The proliferation rates of C6 cells were examined by MTT assay;the changes of cell cycles were examined by flow cytometry;the expression levels of CyclinD1,Bax,Bcl-2 and Caspase-3 proteins in supernant were detected by ELISA assay. Results:Compared with control group, the proliferation rates at 24 and 48 h in 50,100,and 200 mg·L-1 deoxyschizandrin groups were significantly decreased (P <0.01),and the proliferation rates at 72 h in 100 and 200 mg·L-1 deoxyschizandrin groups were significantly decreased (P < 0.05 or P < 0.01 ). Compared with control group, the percentage of cells at SubG1 phase in 200 mg·L-1 deoxyschizandrin group was increased (P < 0.05 ), and the percentage of cells at S phase was decreased (P <0.05).Compared with control group,the expression levels of CyclinD1 in 100 and 200 mg· L-1 deoxyschizandrin groups were decreased (P < 0.01 );the expression levels of Bax protein in deoxyschizandrin groups were increased (P < 0.05 or P < 0.01 ), and the expression level of Bcl-2 protein in 200 mg · L-1 deoxyschizandrin group was decreased (P < 0.01 ), and the Bax/Bcl-2 value in deoxyschizandrin groups were increased (P < 0.01 ); the expression level of Caspase-3 protein in 200 mg · L-1 deoxyschizandrin group was increased (P < 0.01 ).Conclusion:Deoxyschizandrin could inhibit the growth of glioma cells through down-regulating the expression levels of CyclinD1 protein and up-regulating the expression levels apoptotic factors Bax and Bcl-2.
