Objective To evaluate the potential utility of PⅢpeptide in anti peritoneum metastasis in gastric carcinoma cells with high peritoneal metastasis potential(GC9811 P).Methods The adhesion and invasion inhibitory effects of PⅢpeptide on GC9811-P cells were detected by in vitro matrix adhe- sion and cell invasion experiments.By using nude mice metastatic model of human gastric cancer,the effects of PⅢpeptide on peritoneal metastasis of gastric cancer GC9811 P were evaluated.Mice were randomly divided into the experimental(GC9811-P+peptide PⅢgroup)and control groups(GC9811-P +0.9% NaCl solution group),12 mice in each group.At the exhaustion time after inoculation,mice were sacrificed to observe the incidence of peritoneal metastasis,the number of the metastasis foci and the volume of primary tumor.Results Two hours after 40?g PⅢpeptide incubation,the adhesion in hibitory rate reached 86.30%.The adhesion inhibitory effects were in a time dependent manner.The in- vasion inhibitory effects became apparent(81.4%)48 hours after PⅢpeptide insult.After the GC9811- P cells were orthotopic implanted in nude mice and treated with PⅢpeptide,the number of peritoneal metastatic nodes were significantly reduced as compared with control group(3.2?6.5 vs.26.3?5.2) ( P＜0.01).But the mass of primary tumor were (1.9?1.2) g in PⅢpeptide treated group and (2.1?1.0) g in the control group,no difference was noted between two groups(P＞0 05 ).Conclusion PⅢpeptide can markedly inhibit the adhesion,invasion and peritoneal metastasis of gastric carcinoma cell line GC29811-P with high peritoneal metastasis potential

OBJECTIVETo explore the lipid peroxidation and the testicular morphological change induced by decabrominated diphenyl ether (BDE-209) in male BALB/c mice.

METHODSTwenty one male BALB/c mice were randomly divided into three groups: the high exposure group (500 mg/kg BDE-209), the low exposure group (200 mg/kg BDE-20) and control group (normal saline). The mice were exposed by gavage one time a day for 6 weeks, then were sacrificed. Body weight, testis weight, malonyldialdehyde (MDA), total superoxide dismutase (T-SOD) and glutathione (GSH) in testis were examined. The morphological alteration of testis was observed. TUNEL assay was used to detect the apoptosis in testicular cells.

RESULTSBody weight and testis weight in high and low exposure groups were (21.6140 +/- 2.3550) g, (20.8000 +/- 1.7630) g and (0.1859 +/- 0.0349) g, (0.1718 +/- 0.0266) g, respectively, which were significantly lower than those (27.7570 +/- 1.2880) g and (0.2302 +/- 0.0335) g in the control group (P < 0.05); the testis coefficient in high exposure group was (0.8640% +/- 0.1706%), which was significantly higher than that (0.8329 +/- 0.1386%) in the control group (P < 0.05). The GSH level and SOD activities of testis in 2 BDE-209 groups were 0.044 +/- 0.006, 0.039 +/- 0.005 nmol/mg prot, and 0.735 +/- 0.179, 0.907 +/- 0.198 U/mg prot, respectively, which were significantly lower than those (0.052 +/- 0.067) mol/mg and (1.161 +/- 0.188) U/mg in the control group (P < 0.05). The levels of MDA in 2 BDE-209 groups were (2.365 +/- 0.339) and (1.752 +/- 0.366) nmol/mg prot, which were significantly higher than that (1.173 +/- 0.232 nmol/mg prot) in control group (P < 0.05). there were significant differences of SOD and MDA levels between high exposure group and low exposure group (P < 0.05). Histological examination showed that the number of spermatogenic cells and layer were decreased significantly in 2 exposure groups as compared with control group. TUNEL assay showed that apoptosis cells appeared in 2 exposure groups.

CONCLUSIONBDE-209 changed lipid peroxidation in male BALB/c mice testis and caused toxic effects on the testis.

OBJECTIVETo study the accumulation of fluoride in rat hippocampus and its effect on cholinesterase activity.

METHODSRats were subchronically exposed to NaF, and fluoride concentration and cholinesterase activity in rat hippocampus were determined.

RESULTSFluoride concentration in rat hippocampus was significantly correlated with the dosage of fluoride, and there were significant differences among high dosage group [(13.03 +/- 1.79) micro g/g], low dosage group [(9.83 +/- 0.92) micro g/g] and control [(8.27 +/- 1.11) micro g/g], P < 0.01. Acetylcholinesterase activities among three groups [(0.111 +/- 0.031) micro mol/mg, (0.143 +/- 0.025) micro mol/mg, (0.183 +/- 0.027) micro mol/mg] were also significantly different (P < 0.01), which was negatively correlated with fluoride concentration in rat hippocampus (r = -0.700, P < 0.01). The activity of butylcholinesterase in high dosage group [(0.041 +/- 0.010) micro mol/mg] was different from that of control [(0.067 +/- 0.025) micro mol/mg, P < 0.05], but the activity was not significantly related with fluoride concentration in rat hippocampus (r = -0.317, P = 0.094).

CONCLUSIONFluoride may go through the blood-brain barrier and accumulate in rat hippocampus, and inhibit the activity of cholinesterase.

OBJECTIVETo investigate the effects of exposure to decabrominated diphenyl ether (PBDE-209) on learning and memory of BALB/c mice.

METHODSEighteen female BALB/c mice were randomized divided into 3 groups and gavaged with peanut oil in the control groups and 300, 1500 mg x kg(-1)xd(-1) PBDE-209 in peanut oil daily in two exposed groups respectively for 4 weeks. The learning and memory ability of mice were tested by the Morris water maze and the shuttling box respectively. The body weight and organs index were measured and the acetylcholinesterase and butyrylcholinesterase activity in brain were determined. The liver histopathological examination was performed.

RESULTSThe heart index in high dose PBDE-209 group was higher than that of the low dose PBDE-209 group (P < 0.05). The results of Morris water maze showed that escape latency period was significantly shorter than the control group (F = 3.134, P < 0.05). The swimming time in the second quadrant of low dose PBDE-209 group was (15.78 +/- 10.92) s, significantly shorter compared with the swimming time in the second quadrant of the control group's [(28.80 +/- 8.67) s] (P < 0.05). There was no significant difference in the times of active avoidance in the shuttling between three groups (F = 3.423, P = 0.06). There were no significant differences in acetylcholinesterase and butyrylcholinesterase activity in brain of PBDE-209 groups compared with the control group (P > 0.05). Histologically liver damages in structure such as adipose degeneration and swelling were observed in PBDE groups.

CONCLUSIONExposure to PBDE-209 slightly impairs the space learning and memory ability of BALB/c mice, and it has some hepatotoxicity.

Objective: To facilitate the functional analysis of chromosomal genes and their products, the recombineering technique to epitope tagging of chromosomal genes of Y. pestis was adapted. Methods: The epitope tag was generated by primer annealing and then fused with resistance gene by fusion PCR. The epitope-resistance cassette was inserted into pBluecript, resulted in the template plasmid, pBS-MH. The tagging cassette for rpoS was obtained by PCR amplification from pBS-MH with primers containing homology specific to the target gene. PCR products were transformed into recombination competent cells and recombinants were selected. PCR and DNA sequencing were used to confirm the correct tagging event. The expression of the tagged protein was detected with Western blot by using monoclonal antibody to the epitope. Results: The template plasmid containing fusion of epitope and resistance gene was successfully constructed. The sigma factor gene, rpoS, was tagged with a myc-his tag at the COOH terminus. Expression of the tagged rpoS was successfully detected indirectly by the antibody against His tag. Conclusion: The chromosomal gene tagging by recombineering technique represents a powerful tool in the functional study of bacterial genes and their products.

OBJECTIVETo explore the effects of mitogen activated protein kinase (MAPK) and extracellular signal-regulated kinases (ERK) on kidney injury in female BALB/c mice exposed to cadmium.

METHODTwenty-one female BALB/c mice were randomly divided into 3 groups, i.e. control group, low Cd exposure group (2.5 µmol/kg) and high Cd exposure group (10 µmol/kg) were exposed to normal saline, 2.5, 10 µmol/kg Cd, respectively, 3 times a week for 14 weeks. The kidney slice were stained by HE, PAS and Masson staining to observe the morphological changes. The expression levels of pERK, ERK, pp38, p38, pJNK and JNK proteins in kidneys were tested by Western blot assay.

RESULTSThe ratios of pERK/ERK, pp38/p38, pJNK/JNK in high Cd group were higher than those in the control group (P < 0.05). The ratio of pERK/ERK in low Cd group was higher than control group (P < 0.05). The expression levels of bcl-2, bax proteins and the ratio of bcl-2 to bax in Cd exposure groups decreased significantly, as compared with the control group (P < 0.05). The impairment of renal glomeruli and tubules were observed in HE, PAS and Masson staining slices of kidneys in mice exposed to Cd.
