Objective To study the effect of DNA damage induced by H2 O2 on the micronucleus frequency in lymphocytes. Methods Resting lymphocytes were treated with different levels of H2 O2 (10,50,100,1 000 μmol/L).1 000 μmol/L H2 O2 was added into mitogen-stimulated lymphocyte cultures at different time intervals.Then micronucleus rate was examined by the conven-tional culture method.Results There was no significant change of the micronucleus frequency in the experimental groups.Conclu-sion H2 O2 could induce lymphocyte DNA damage rapidly,but exerts no effect on the formation of micronuclei,which may be relat-ed to the type of DNA damage and rapid DNA repair.

This study is to determine six chlorogenic acids (chlorogenic acid, 5-O-caffeoylquinic acid, 4-O-caffeoylquinic acid, 3,4-di-O-caffeoylquinic acid, 3,5-di-O-caffeoylquinic acid and 4,5-di-O-caffeoylquinic acid) by quantitative analysis of multi-components with a single marker (QAMS). Chlorogeinc acid was used as internal reference to calculate the relative correction factors (RCF) of five compounds. Then the ruggedness of relative correction factors was tested on different instruments and columns. Meanwhile, a total of 4 batches of Lonicerae Flos and 20 batches of Lonicerae Flos extract with five different processing procedures were analyzed by external standard method (ESM) and QAMS, respectively. The ruggedness of relative correction factors was good. And the analytical results calculated by ESM and QAMS showed no difference. The quantitative method established was suitable for the quality evaluation of Lonicerae Flos extract.

Objective To study the role of manganese-enhanced MRI(MEMRI) in the depiction of cortical architecture of rat brain after systemic administration of Mn~(2+) through caudal vein and compare the effects of normal or opened blood-brain barrier on the manganese-enhanced MRI. Methods Fifteen SD rats were randomly divided into three groups according to ranked list of random. Blood-brain barrier was opened in short time by the injection of 30% mannitol via the right internal carotid artery, in group A, then 100 mmol/L MnCl_2 physiologic saline solution was delivered through vena caudalis, and MRI was performed 12 hours later. In group B, 100 mmol/L MnCl_2 physiologic saline solutions was administrated through vena caudalis, following normal saline injection into the right internal carotid artery, and MRI was performed 12 hours later. The group C served as normal control group. All images were acquired with a 7.0 T microMR scanner. Signal-to-noise ratios (SNR) in regions of interest were measured by Paravision 4.0 and the differences of three groups were compared by using one-way ANOVA. The differences of SNR on both sides of hemispheres were compared by using paired t test. Results MEMRI could show the gray matter and white matter of rat brain and the anatomy borders between somatosensory cortex and motor cortex clearly. Periventricular structures such as hippocampus, dentate gyms, habenula united, and olfactory bulb could also be showed clearly. Symmetrical enhancement on both sides of the cortex and banded structures was shown clearly in group B. The SNR increased and the differences were significant in right cerebral cortex, both sides of cerebellar cortex, hippocampus and pituitary, among three groups (right cerebral cortex 35.2±7.0,30.1±2.4,26.6±2.8,F =4.36,P=0.038;left cerebellar cortex 27.1±5.2,29.4±3.8,19.4±4.5, F=6.66, P=0.011;right cerebellar cortex 27.8±3.8,28.5±4.2,20.4±4.8, F=5.84, P=0.017; left hippocampus 34.5±4.9,38.1±5.3,24.5±3.6, F=11.38, P=0.002; right hippocampus 35.3±5.5, 37.6±4.7,25.6±3.0,F=9.93,P=0.003;pituitary 39.5±3.8,52.6±9.1,26.2±4.2,F=22.80, P=0.001) after systemic administration of Mn~(2+). Asymmetric enhancement on two sides of cortex was shown in group A. The mannitol-infused side was enhanced obviously but displayed blurring banded structures. However,the SNR differences of both sides of hemispheres in group A and B were not significant (P >0.05). Conclusions After systemic administration of MnCl_2 through vena caudalis, MEMRI could map the laminar architectures and the anatomy border of functional zone of somatosensory cortex specifically. High concentration of mannitol could open blood brain barrier(BBB) effectively and have distinct impacts on the architectures displayed in MEMRI. Opening or maintaining BBB in MEMRI had respective characteristics, and it should be selected according to practical needs.
