In the present paper, we measured DNA content of uninuclear Plasrnodium berghei traced with DAPI by means of fluoromi-crospectrophotmeter. The results indicate that the DNA replication of parasite was continuous and it's content was high polyploidy and phase G1 of proliferating cycle was not evident. The dispersion degree of distribution of DNA content in P. R. was markedly lower and the peak sitewas more concentrated and obviously shifted to the right compared with P. N. It was suggested that the speed of DNA replication and proliferating vitality of parasites after producing resistance to SA markedly decreased, indicating that the changes of proliferating kinetics of P. R. happened.

Objective To understand the prevailing status of coal-burning endemic fluorosis in Henan, and to provide scientific grounds for endemic fluorosis prevention. Methods Undertook general surveillance on factors such as coal using, living habit, main foods, the structure of the houses and the fluoride content in drinking-water among 1832 historical coal-burning endemic fluorosis villages within 13 counties in 2006 and 2007, and conducted focal point sampling survey on 216 villages which still using local high-fluoride. For all children aged 8-12 years of each village, conducted dental fluorosis examination and collected 30 immediate urinary samples for fluoride content determination. Results The fluoride content in drinking-water of all historical fluorosis villages was below 1.0 mg/L. Households having individual kitchens accounted for 93.7%(241 281/257 393), those with stoves having smoke evacuation devices accounted for 41.9% (107 917/257 393), those using local high-fluoride coal for cooking accounted for 28.6%(73 686/257 393), those using local high-fluoride coal for heating accounted for 24.1%(61 924/257 393). Villages with serf-supply of main foods accounted for 95.7%(1753/1832) of all fluorosis villages. Solar drying food was used in all households. Villages with dental fluorosis detection rate for children aged 8 to 12 years above 30.0% accounted for 16.2%(35/216), which axe all in Luoyang City. Among 77.8%(168/216) of fluorosis villages, children' s urinary fluoride concentrations were no higher than 1.50 mg/L. Conclusions Coal-burning endemic fluorosis areas in Henan Province were decreased greatly and the extent of the health hazard was becoming slightly. The detection rate of dental fluorosis for children aged 8 to 12 years of 8 counties had reached the standard for fluorosis control, whereas the other 5 counties had not yet, all located in Luoyang City.

To simulate intervention measures in controlling an outbreak of acute hemorrhagic conjunctivitis on one school campus by using the Susceptible-Infected-Recovered (SIR) model, to provide evidence for preparedness and response to the epidemic. Classical SIR model was used to model the epidemic. Malthusian exponential decline method was employed to estimate the infective coefficient β for interventions. The initial value of parameters was determined based on empirical data. The modeling was implemented using Matlab 7.1 software. Without interventions, the outbreak was expected to experience three phrases: (1)early stage (the first 5 days) in which the epidemic developed slowly and could be intervened easily; (2) rapid growing stage (6-15 days) in which the number of infected cases increased quickly and the epidemic could not be well controlled;and (3) medium and late stage (16 days and later) in which more than 90% of the susceptible persons were infected but the intervention measures failed to prevent the epidemic. With the implementation of interventions, the epidemic was predicted to be controlled in the early stage, under the SIR model. The simulation based on the SIR model kept an acceptable consistency with the actual development of epidemic after the implementation of intervention measures. The SIR model seemed effective in modeling interventions to the epidemic of acute hemorrhagic conjunctivitis in the schools.

AIMTo develop a method for determination of chlorogenic acid and eriodictyol-7-O-beta-D-glucuronide in Pyrrosia of different species and different places of origin by RP-HPLC.
METHODSChromatography was performed using a C18 column with mobile phase of methanol-water-phosphoric acid (50:200:0.2). The monitoring wavelength was 284 nm.
RESULTSThe linear ranges were 0.01-5.0 micrograms (r = 0.9997) and 0.004-5.0 micrograms (r = 0.9997), the recoveries were 97.1% (n = 8, RSD = 2.7%) and 98.8% (n = 9, RSD = 2.5%) for chlorogenic acid and eriodictyol-7-O-beta-D-glucuronide, respectively.
CONCLUSIONThe method was employed to the analysis of 21 samples of Pyrrosia. The contents of compounds vary greatly depending on the species used, place of collection and time of harvesting. The HPLC method is sensitive, rapid and can be used to control the quality of Pyrrosia and to guide reasonable season of harvesting.

OBJECTIVETo study the effect of budesonide aerosol inhalation on the expression of glucocorticoid receptor (GR) and nuclear factor (NF)-κB in asthmatic mice.
METHODSTwenty-four healthy male BALB/c mice aged 6 to 8 weeks were randomly divided into three groups (n=8 each): normal saline (control group), asthma model (asthma group) and budesonide-treated asthma (BUD group). Asthma was induced by intraperitoneal injection of ovalbumin (OVA) and aluminium hydroxide suspension and aerosol inhalation of OVA solution. Mice were sacrificed 24 hours after the last challenge. Eosinophil count in the bronchoalveolar lavage fluid (BALF) was determined. Pathological examination of the lung tissues was performed and the expression levels of GR and NF-κB were measured by immunohistochemical analysis.
RESULTSEosinophil count in the BALF was significantly higher in the asthma and BUD groups than in the control group (P<0.05). BUD treatment decreased eosinophil count in the BALF compared with the asthma group (P<0.05). The lung tissues in the BUD group showed a less severe infiltration of eosinophils and lymphocytes compared with the asthma group. The percentage of GR-positive cells in the asthma group decreased significantly compared with the control group (P<0.05), and the percentage of GR-positive cells in the BUD group increased significantly compared with the asthma group (P<0.05). Compared with the control group, the percentage of NF-κB-positive cells increased significantly in the asthma group (P<0.05), and the percentage of NF-κB positive cells in the BUD group was significantly reduced compared with the asthma group (P<0.05).
CONCLUSIONSThe action mechanism of budesonide in treating asthmatic mice may be related to the upregulation of GR expression and the inhibition of NF-κB activity.

OBJECTIVETo investigate the susceptibility to carbon tetrachloride and benzene in offspring of expanded simple tandem repeats (ESTR) mutation mice exposed to formaldehyde (FA).
METHODSF5 and F10 offspring (200 mg/m3 x 2 hours) served as H group and ICR mice were used as control group (group C). The F5 and F10 offspring were exposed to 10 ml/kg carbon tetrachloride at the doses of 0.05%, 0.50% or 5.00% for 24 hours, respectively or 500 or 1000 mg/kg benzene for 24 hours, respectively by intraperitoneal injection. Serum alanine transaminase (ALT), aspartate transaminase (AST) and the hepatic superoxide dismutase (SOD) or malondialdehyde (MDA) were detected; also the hepatic pathological changes were observed under light microscope; the micronucleus in sternum bone marrow cells as the biomarker of benzene blood toxicity were measured.
RESULTSALT and AST activities in group C of F5 mice exposed to 0.50% and 5.00% CCl4, ALT in groups C and H of F10 mice exposed to 0.05%, 0.50%, 5.00% CCl4, AST in groups C and H of F10 mice exposed to 0.50% and 5.00% CCl4 were significantly higher than those in controls, respectively (P<0.05); as compared to the control, hepatic SOD activities in group C of F5 and F10 mice exposed to 0.50% and 5.00% CCl4, in group H of F5 mice exposed to 0.50% and 5.00% CCl4 and F10 mice exposed to 5.00% CCl4 were significantly reduced, respectively (P<0.05); however, MDA contents in group C of F10 mice exposed to 0.50% and 5.00% CCl4, in group H of F5 mice exposed to 0.05% and 0.50%, 5.00% CCl4 and F10 mice exposed to 0.50% and 5.00% CCl4 were significantly increased than those in control group, respectively (P<0.05). The susceptibility to CCl4 in ESTR mutation F5 mice exposed to FA was significantly higher than that in control F5 mice, but the susceptibility to CCl4 in ESTR mutation F10 mice exposed to FA was significantly lower than that in control F10 mice. The histopathological examination showed that the injury of hepatocytes in C and H groups significantly increased CCl4 doses, and the injury of hepatocytes in H group was higher than that in C group. The micronuclear rates in C and H group mice exposed to benzene(500 mg/kg C group, F5 and F10 mice; 1000 mg/kg C group, F5 and F10 mice; 500 mg/kg H group, F5 and F10 mice; 1000 mg/kg C group, F5 and F10 mice) were 5.88 per thousand +/- 4.55 per thousand, 8.25 per thousand +/- 2.06 per thousand, 7.50 per thousand +/- 6.99 per thousand, 10.67 per thousand +/- 1.16 per thousand, 7.88 per thousand +/- 3.09 per thousand, 9.20 per thousand +/- 1.30 per thousand, 9.63 per thousand +/- 4.34 per thousand and 13.33 per thousand +/- 2.08 per thousand, respectively, which were significantly higher than those (1.13 per thousand +/- 0.35 per thousand, 1.20 per thousand +/- 0.82 per thousand, 1.25 per thousand +/- 0.46 per thousand, 1.33 per thousand +/- 1.03 per thousand) in the solvent control group (P<0.05 or P<0.01).
CONCLUSIONFA could result in the change of susceptibility to CCl4 and benzene in offspring of ESTR mutation mice. ESTR mutation may be a biomarker of the susceptibility to chemicals, but the molecular mechanisms should be investigated in the future.
