Sepsis is an organ dysfunction caused by a dysregulated immune response to an infection, the initial therapeutic approach to sepsis are broad spectrum antimicrobials, which is not sufficient for control of infection, requiring association with other therapies focused in the interruption of the inflammatory response chain, provided by the pathogens. In this way, the Aedes Aegypti’s saliva presents immunomodulary features, with a potential pro inflammatory cytokine inhibition, as well as the presence of nitric oxide peptides activators. Therefore, it would be a great interest to search the saliva’s immunomodulator effect in animal model sepses. In this regards, mices were pre treated with Aedes aegypti saliva, and sepsis was induced by the cecal ligation and puncture. After 12 and 24 hours, the samples were collected, and evaluated the survival rate, bacteria level, leukocyte migration, and oxidative parameters (NO, EROs, MDA e TEAC). The saliva improved the animal prognostic, increasing the survival rate and weight. Furthermore, decreased the bacterial levels and increased the influx of monocytes. The saliva, in addition, presented antioxidant effects by reducing production of the reatives species, and increasing the antioxidant capacity, other than decrease the lipid peroxidation. Thus, the saliva was capable to inhibit damages caused by sepsis in animals in vivo, improving its prognostic.

Perfil clínico-epidemiológico de saúde bucal em pacientes de hanseníase
(Universidade Federal do Pará, 2009) SANTIAGO, Roberta Souza D'Almeida Couto; BARROSO, Regina Fátima Feio; http://lattes.cnpq.br/6485426116453902; SALGADO, Claudio Guedes; http://lattes.cnpq.br/2310734509396125
The aim of this study was to evaluate the clinical-epidemiological profile of oral health in leprosy patients at multidrug terapy (MDT) through the oral mucosa clinic assessment, the VPI (visible plaque index), GBI (gum bleeding index), DMFTI (decayed, missing and filled teeth index) and salivary flow rate measure by SSI (salivary secretion index) as epidemiological indicators, well over buffeing capacity by salivary pH. The sample was 80 patients, aged from 8 to 73 years submited to the analysis of the oral conditions and stimulated saliva collection, divided in study group (SG) constituted of 40 leprosy patients in MDT carried in the CRTDS Dr. Marcello Candia Marituba-Pa, Brazil and control group (CG) of 40 no leprosy patients. The results pointed 62,5% unspecific oral lesions, among the most frequent was melanin pigmentation of the attached gingiva, mordiscatum line of the buccal mucosa, gingival inflammation, tongue varicose veins and trauma for use of prosthesis, without statistical significant difference (p=0,14) with the CG. The average of the VPI was 50,4 % of the dental surfaces with accumulation of bacterial plaque, without statistical significant difference (p=0,40) with the CG. The VPI was bigger in the individuals without access to the odontologic service and while it increased the degree of incapacity of the patients, juvenile was the access to the service. The average of the GBI was 29,7% of the dental surfaces with gingival bleeding, without statistical significant difference (p=0,35) with the CG. The middle DMFTI was of 11,6 varying from 4,0 to 24, which increases with the advancement of the age. The biggest accumulation of plaque, the gingival bleeding and the consumption of foods cariogenic out of the time-table of the meal also contributed to the increase of the DMFTI. Another factor made a list to the increase of I DMFTI was no access it to the odontologic service for 70 % of the leprosy patients, having statistical significant difference is (p=0,0005) with the CG and the lack of education of oral hygiene in 60 %, having statistical significant difference (p=0,01) with the CG. The middle SSI was of 0,9ml/min and did not present association with the MDT and not even with the use of prednisolone. The SG patients, 25 % presented hiposalivation, but there was no increase of DMFTI and none of the groups revealed alteration of salivary pH , varying from 5,85 to 7,34, with buffeing capacity inside the standard of normality. Conclusion that the clinical-epidemiological profile of leprosy patients is similar to the control group, do not have find specific oral lesions for leprosy, which does not cancel the possibility of the buccal cavity to be a fountain of infection for leprosy, needing histopathological confirmation and / or PCR for detection of viable M.leprae. Moreover, the data showed most of the leprosy patients do not have access to the odontologic service and not even education of oral hygiene, results absence of public politics of oral health for leprosy.
