Objective To investigate the possible mechanisms of teratogenesis caused by passive smoking, temporospatial changes in surface carbohydrates of the embryonic neural epithelium and the mesenchyme around it were explored. Methods The pregnant golden hamsters were randomly divided into the treated group and the control groups. In the chamber made by ourself for passive smoking experiment, the animals of the treated group were exposed to smoke from embryonic day 4 to 7, 3 times per day for 4 consecutive days. At twelve o'clock and eighteen o'clock of embryonic day 8, eight o'clock of embryonic day 9 and eight o'clock of embryonic day 10 respectively, the pregnant golden hamsters of both treated group and control group were sacrificed, the uteri were removed and embedded routinely with paraffin, sectioned transversely in series. The sections of each group were stained with immunohistochemical ABC method and concannavalin agglutinin (ConA) and ulex europaeus agglutinin (UEA) were used as molecule probes to conduct the qualitative and quantitative analysis of the fibronectin and the related surface carbohydrates of the embryonic neural epithelium and the mesenchyme around it. Results During embryonic day 8 to10 of golden hamsters fibronectin reduced(F=30.168,P

Objective To investigate the characteristics and extent of mononuclear ceils DNA damage in peripheral blood of mice fed with low dose T-2 toxin and Deoxynivalenol(DON) alone or in combination and to explore the long-term toxicity of the toxin at sub-clinical dose. Methods Eighty female Balb/c mice weighing (14.0 ± 1.5)g 3 weeks after birth were divided randomly into control group, T-2 toxin group, DON group and T-2 toxin combined with DON group according to their body weight, 20 in each group. The mice were injected intraperitoneally T-2 toxin(5 μg·kg-1·d-1), DON(20 μg·kg-1·d-1), T-2 toxin(5 μg·kg-1·d-1) combined with:DON (20μg·kg-1·d-1)respectively,control group were treated by isotonic NaCl. In 16 weeks and 21 weeks of exposure, the tail blood of the mice was collected. The comet rate, tail DNA content,tail length and tail extent moment of mouse mononuclear ceils in peripheral blood was observed using single cell gel electrophoresis(SCGE). Results ① In T-2 toxin group,tail DNA content,tail length and tail extent moment were (27.71 ± 15.85)%, (13.67 ± 5.56)μm, 4.26 ± 3.83 at 16 weeks and (28.38 ± 15.57)%, (13.83 ± 5.47)μm, 4.37 ± 3.82 at 21 weeks, all levels of the indexes increased. In the control group, the corresponding values were (11.87 ± 4.61)%, (10.59±6.70)μm, 1.34±0.98 at 16 weeks and (11.31 ± 3.94)%, (10.83 ± 7.05)μm, 1.29±1.01 at 21 weeks, the differences in the two groups were significant (all P < 0.05) ;②In DON group, the comet rate of cells, tail DNA content and tail extent moment of comet ceils were 5.62%, (28.13 ±13.31)%, 3.39 ± 2.35 at 16 weeks and 7.71%, (29.17 ± 15.12)%, 5.70 ± 4.17 at 21 weeks. In the control group, the tailing rate was 4.34% at 16 weeks and 4.38% at 21 weeks, the differences in the two groups were significant (all P < 0.05);③In the group of T-2 toxin combined with DON,the comet rate, tail DNA content, tail length and tail extent moment was 6.21%, (30.14 ± 15.48)%, (16.93± 6.58)μm, 5.54 ± 4.22 at 16 weeks and 8.17%, (30.85 ± 15.76)%, (17,21±6.45)μm, 5.70 ± 4.17 at 21 weeks. Moreover, the levels were significantly higher than that in the control group(all P < 0.05). The tail DNA content and length of comet cell tail significantly increased in the combine group compared with T-2 group or DON group(P < 0.05). Conclusions Low dose T-2 toxin or DON can definitely result in DNA damage of mononuclear cells in peripheral blood of mice. The damage induced by T-2 toxin combined with DON is severer than that caused by T-2 toxin or DON alone.

Objective To explore the correlation between executive function and white matter lesions (WML) and the diagnostic value by clock drawing test(CDT) in patients with vascular dementia (VaD). Methods Twenty-seven VaD patients and twenty-five normal control subjects were evaluated with CDT to assess the executive function. CDT was scored according the four point method. Age-related white matter change rating scale (ARWMCrs) was used qualitatively to measure and locate the WML by cranial MRI scanning. Results 1. The scores of CDT in normal cognition health and VaD were ( 3.88 ± 0. 33 ) and ( 1.74 ± 0. 98 ). The difference between two groups was statistically significant (P＜0. 01 ). The humerous part and the point part were the earliest to decline in the VaD Patients. The scores of WML were (5.12 ± 4. 19) and ( 11.19± 3.09), respectively. There was significant difference between two groups(P ＜ 0. 01 ). The scores of CDT had significant positive correlation with MMSE scores and negative correlation with WML scores (P ＜ 0. 01 ). Conclusion The executive functional impairment in patients with VaD could be associated with the degree of WML.
