RESUMO
Objective To investigate the effect of antidepressants on frontal lobe inflammatory factors in depressed model rats.Methods Thirty SD rats were randomly divided into 5 groups (n=6):contorl group(Cn),depression group (Dn),citalopram group (Dx),venlafaxine group (Dw) and reboxetine group (Dr).The open field test and sugar consumption test were performed to observe the depression behavior and the changes of FGF-1,TNF-α,IL-1 and CRP were measured in frontal lobe of rats by ELISA.Pearson linear correlation analysis was used to evaluate the correlation between behavioral score and inflammatory factors level in rats.Results (1)Compared with the Cn group,the scores of Dn,Dr,Dw,Dx group were decreased on Open field test and sugar consumption test (P＜0.05).Compared with the Dn group,the scores of the Dx,Dw,Dr group were increased in Open field test and sugar consumption test (P＜0.05).(2)Compared with Cn group,the levels of TNF-α,IL-1 and CRP increased in Dn group and FGF-1 level decreased (P＜0.01).Compared with Dn group,the levels of FGF-1 increased in Dx ((86.54±2.56) ng/L),Dw((79.82±4.89) ng/L)and Dr ((68.50 ± 3.61) ng/L) group,however,the levels of TNF-α decreased in Dx ((150.21±5.65) ng/L),Dw ((161.28±8.80) ng/L),Dr ((175.78±9.67) ng/L) group,and the level of IL-1 also decreased in Dx ((30.87±4.48) ng/L),Dw ((36.65±3.33) ng/L),Dr ((40.14±2.81)ng/L) group,and the levels of CRP also decreased in Dx ((374.88 ± 14.15) ng/L),Dw ((394.21 ± 17.03) ng/L),Dr ((414.34± 10.97)ng/L) (P＜0.01).(3)The behavioral score of each group was positively correlated with of FGF-1 and negatively correlated with TNF-a,IL-1 and CRP (P＜0.05).Conclusion Antidepressants can reduce the level of proinflammatory factors and increase the level of anti-inflammatory factors of frontal lobe in depression model rats,suggesting that antidepressants may play an antidepressant effect by regulating the concentration of inflammatory factors.
RESUMO
@#ObjectiveTo evaluate the correlation between the promoter polymorphism of Fibroblast Growth Factor 1 (FGF-1) and late-onset Alzheimer's disease (LOAD). MethodsClinic pathological data from 206 autopsies were analyzed, including 100 autopsy-confirmed LOAD patients and 106 age-matched non-demented controls. PCR-RFLP (Restriction fragment length polymorphism) approach was used to determine the genotype of the promoter polymorphism of FGF-1 gene. ResultsThe genotyping frequencies of the promoter polymorphism (-1385 A/G) were AA 20 (10%), GA 89 (43%), GG 97 (47%), respectively. There was significant (P=0.027) difference of genotyping frequencies between the cases and controls; GG genotype was positively associated with LOAD (odds ratio=2.02, 95%CI:1.16～3.52). ConclusionThe promoter polymorphism (-1385 A/G) of FGF-1 gene was associated with LOAD.
RESUMO
Fibroblast growth factor(FGF) is a mitogen and a potent antigenic factor. It is also known as a differentiation factor for neuroectodermal-derived cell. It has been observed to be expressed in more than 90% of m-RNA of human meningiomas and gliomas. Progesterone receptor(PR) is well known surface receptor of meningioma and its number is greater than that of estrogen receptor. It is one os the known prognostic factors of meningioma. Meningiomas themselves are regarded as benign tumors in general, however some types show aggressive features. In the present study, authors examined the expression of FGF-1 and PR in meningioma tissues using immunohistochemical techniques with monoclonal antibody against human FGF-1 and PR. FGF-1 was detected in 25 of 35 classic meningiomas and in 7 of 9 aggressive ones. PR is expressed in 5 cases of classic and 2 cases of aggressive meningiomas. These results suggest FGF-1 may be involved in aggressive progression of meningioma. There was no significant difference of aggressiveness and expression of FGFR-1 and PR between classic and aggressive meningiomas, including their subtypes.
