Objective By discussing the relationship between allergic diseases caused by pollen,pollen density and meteorological factors,making out the warning for the allergic diseases caused by pollen,in order to provide a public service.Methods The data of meteorology from 2001 to 2005 of Tianjin,the pollen monitoring of the Weather Iron Tower Station day by day and the allergic patients whose skin tests were positive in Tianjin Municipal Chest Hospital and Tianjin Municipal Police Hospital were taken to statistical analysis on the rule of seasonal allergic diseases,the relationship between allergic diseases and pollen density and meteorological factors(such as vapor pressure and wind speed),and the prediction equations were obtained for allergic diseases caused by pollen.Results There was obviously positive correlation between the incidence rate of pollinosis(y),weighted pollen density(x11) and vapor pressure(x22) within twenty-days before the onset.The multiple correlation coefficient was 0.805 and the prediction equation was y =2.385+ 0.079 3x11 +3.507x22.Conclusion There is a close correlation between the incidence rate of pollinosis and pollen density.The allergic diseases caused by pollen are also affected by the change of air temperature,varieties of pollen and humidity.

brain and fatty. The accumulation excretion ratios within 96 h were 70.16% in urine and only 1.35% in feces after iv administration in rats, while within 24 h was 3.46% in bile. Conclusion The results of pharmacokinetics of novel r-hirudin in rats given by iv determined by RA are different from those determined by TCA-RA, but the trends indicated by the two methods are the same; urine excretion is the major excretion pathway.

AIM: In order to investigate the possible cumulative and chronic toxicity of paralytic shellfish poisoning (PSP) and provide more information on toxicity of PSP. METHODS: The sub-acute toxicity of PSP was evaluated in the rat. PSP was extracted from the seafood in market, and the toxicity of the extract was determined by mouse bioassay. The extracts in different toxicity were administrated to rats through gastrotube for 35 days. The biochemical and pathological changes in vital tissues in rats were examined by the detections of some function indexes in blood and urine and the observations under optical microscope during both the exposure period and the subsequent 10-day withdrawal term. RESULTS: No biochemical and pathological changes in tissues occurred for the control and low-dose group (4.6 ?g STX/kg), whereas some changes happened for the middle (9.2 ?g STX/kg) and high groups (18.4 ?g STX/kg). In experiment, some renal function indexes changed in the mid-dose group, and some of the cardiac, hepatic and renal functions indexes altered for the high dose group with some changes in weight of the thymus gland and spleen. What is more, the liver and kidney became indistinct with some inflammatory changes, and some muscles had ruptured for the 40% rats in high-dose group. CONCLUSION: These results suggest that long-term intake of PSP at a concentration, which doesn't exceed the threshold of standard, has some toxicity on rats, and that the toxicity of PSP has an accumulative effect. In a word, it is unsafe for us to eat frequently bivalve seafood polluted by PSP toxins.

Objective To study dynamic changes of T cell subsets and CD3+HLA-DR+T cells in peripheral blood of composite tissue transplantation-hand allograft recipients. Methods The levels of CD3+、CD3+CD4+、CD3+CD8+、CD3+HLA-DR+T cells and ratio of CD4/CD8 in peripheral blood of hand allograft recipients in different periods were examined by using flow cytometry.The recipients before transplantation were as the control groups.Results The first day after transplantation,the levels of CD3+、CD3+CD4+、CD3+CD8+、CD3+HLA-DR+T cells and ratio of CD4/CD8 all began to descend.The 3th to 5th day after transplantation,the levels were the lowest.The 8th day,the levels of CD3+、CD3+CD4+、CD3+CD8+、CD3+HLA-DR+T cells and ratio of CD4/CD8 were eventually rised and go to stable 15th day after transplantation.But the levels of CD3+、CD3+CD4+and value of CD4/CD8 were still lower than those of the contols,and the levels of CD3+CD8+、CD3+HLA-DR+T cells were higher distinctly.Conclusion Dynamic changes of T cell subsets and active T cells in peripheral blood of composite tissue transplantation-hand allograft recipients were accordant with that of renal allograft recipients with stable period and with stable clinical state of the hand transplantation recipients.

Objective Porphyromonas gingivalis(Pg)is one of the main putative pathogens of periodontal disease,espcially of adult periodontitis. This in vitro study was aimed at observing the inhibition actions of 3 kinds of antimicrobial drugs on Pg. Methods 106 stains of Pg were isolated from subgingival plaques with adult periodontitis. The agar diffusion test was used to detect the inhibition actions of metronidazole,clindamycin and tinidazole on 106 stains of Pg. Results Their MIC was respectively:0. 25mg/L,0. 6rng/L. The MIC90 of tinidazole<MIC90 of clindamycin. The results showed:all of metroidazole, tinidazole and clindamycin can be used effectively against Pg,clindarnycin and tinidazole showed more potent antibacterial activity than metronidazole. The different concentration of Pg-liquid (l05 CFU/ml, 106 CFU/ml and 108 CFU/ml) had not influenced the results. Couclusion This study is significant to antibiotical therapy of periodontal diseases.

ObjectiveTo determine the levels of type Ⅳ collagen and matrix metalloproteinase-9 ( MMP-9 ) in the serum and kidney of rats with the multiple organ dysfunction syndrome ( MODS ) and investigate the mechanism of extracellular matrix damage in renal failure of MODS.MethodsForty adult male Sprague- Dawley (SD) rats were randomly (ramdom number) divided into two groups,namely the normal control group ( n =8 ) and the MODS model group ( n =32 ).The rats of model group were further divided into four sub-groups as per different intervals,6 h,12 h,24 h and 48 h,after modeling (n =8 in each).The animal models of MODS were established by two hits,the left eyeball of each model rat was removed to bleed to 2 ml bloocd/100 g body weight and lipopolysaccharide ( LPS,5 mg/kg) was injected into intraperitoneal cavity of model rats four hours later. The same volume of saline instead was injected intraperitoneally into rats of control group.All rats were sacrificed at different intervals.Creatinine (Cr)and blood urea nitrogen (BUN) were determined by using a Hitachi Automatic Biochemical Analyzer.The histological changes in renal tissue were observed under light microscope and transmission electronic microscope.The levels of serum type Ⅳ collagen and MMP - 9 protein were measured by using enzyme linked immunosorbent assay (ELISA).Type Ⅳ collagen and MMP- 9 protein levels in renal tissue were detected by western blot.One - way ANOVA was used for comparison among multiple groups.Results Compared with the control group,Cr and BUN were significantly higher in MODS group ( P <0.05 ).There were no histopathological changes in kidney of rats in control group,and the renal injury was serious in rats with MODS.The remarkable edema of basement membrane and defect of collagen fibers in renal tissue were observed in MODS group.Compared with the control group,the levels of MMP-9 in serum increased 6-48 hours after modeling and peaking at interval of 12 hours after modeling ( P < 0.05 ).The protein levels of type Ⅳ collagen increased not significantly in 6 h group and 12 h group in comparison with control group (P > 0.05 ),while those in 24 h group and 48 h group significantly increased ( P < 0.01 ).The levels of MMP -9 in renal tissue of rats with MODS increased in 6 h group and 12 h group (P<0.05),peaked in 24 h group ( P < 0.05 ),and decreased in 48 hours.However,the level of Ⅳ collagen in serum of rats with MODS decreased significantly 6-48 hours after modeling (P < 0.05 ) Conclusions The injury of extracellular matrix is an important factor to the kidney damage in MODS and it may he used for early diagnose and as a treatment target for kidney injury in MODS.
