RESUMO
The study was carried out to find the relation between subclinical endometritis (SCE) and postpartum (pp.) ovarian resumption as well as to evaluate serum and endometrial TNF-α, IL-8 and serum CRP in buffaloes with and without SCE. Thirty-nine pluriparous buffaloes at the 3rd (W3), 5th (W5) and 7th (W7) week pp. were involved in this experiment. The parity of the buffaloes ranged from 4 to 8 with an average 5.8±0.2. Subclinical endometritis was diagnosed by the percentage of polymorphonuclear cells (PMNs) in uterine cytology obtained from endometrial cytobrush at W5 and W7. The cut-off point of PMNs% in buffaloes for SCE was ≥ 6% at W5 or ≥ 4% at W7. According to PMNs%, buffaloes were divided into SCE group (n=27) and non-SCE group (n=12). Ovarian cyclicity was monitored by rectal palpation, ultrasonography and progesterone assay at W3, W5 and W7. Serum and endometrial TNF-α, IL-8 and serum CRP were estimated at W5 and W7. Buffaloes with SCE (55.6%) showed delayed ovarian activity as compared to non-SCE (16.7%) animals (P=0.036). Significant increase in serum cytokines and CRP levels were detected at W5 (P Ë0.05) and W7 (P <0.01) in SCE buffaloes as compared to non-SCE. Endometrial levels of cytokines were significantly (P Ë0.05) elevated in SCE buffaloes. Serum and endometrial cytokines showed significant positive correlation. Furthermore, levels of TNF-α, IL-8 and CRP exhibited significant positive correlation with PMNs%. In conclusion, SCE delayed postpartum ovarian cyclicity in buffaloes. Moreover, TNF-α, IL-8 and CRP assessments could be efficient tools in prediction of SCE in buffaloes.

Abstract: objective: to determine the prevalence of carious lesions and gingivitis in 2- to 4-year-old children attending JUNJI daycare centers and urban municipal schools in the city of Valdivia, Chile. material and method: descriptive cross-sectional study. a population of 182 two-year-old children and 285 four-year-old children were examined. subjects were selected by stratified random sampling. all subjects were enrolled in daycare centers managed by JUNJI and municipal schools in the city of Valdivia. an oral examination was performed to measure the DMFT and hemorrhagic indexes according to the WHO diagnostic criteria. the presence of cavitated carious lesions and gingivitis was determined, resulting in descriptive statistics according to age and gender. results: the prevalence of caries was 12.6 percent in two-year-old children and 41 percent in four-year-olds, respectively. the prevalence of gingivitis was 36.8 percent at 2 years of age and 70.5 percent at 4 years. there were no significant differences by gender at 2 years of age (p=1) or at 4 years (p=0.37). two year-old children have significantly fewer carious lesions and gingivitis less frequently than four-year-olds (p=<.001). conclusion: two year-old children have a lower prevalence of carious lesions and gingivitis than four-year-old ones. no relationship between the variables and gender was found.

INTRODUCTION: Interleukin (IL)-18 is a well-known major proinflammatory cytokine with broad biological effects. The major immunomodulatory functions of IL-18 include enhancing T cell and natural killer cell cytotoxicity. Serum levels of this cytokine were shown to increase in chronic hepatitis C patients compared to non-infected healthy people. An association between IL-18 gene promoter polymorphisms and pegylated interferon (PEG-IFN) and ribavirin treatment outcomes has been reported for individuals with chronic hepatitis C virus genotype 1 (HCV-1). In this study, HCV genotype 4 (HCV-4) patients were assessed for IL-18 gene polymorphisms and treatment outcomes or severity of liver disease because data concerning the impact of IL-18 gene polymorphisms on patients with HCV-4 infections are limited. METHODS: This study included 123 chronic HCV-4 Egyptian patients and 123 apparently healthy volunteer blood donors who served as a control group. HCV genotyping was performed using the line probe assay. IL-18 genotyping was performed using the TaqMan Real-Time PCR method in all 246 patient and control samples. RESULTS: In our study, all patients had HCV-4. IL-18 gene single nucleotide polymorphism (SNP) (-607C/A) genotype distributions and allele frequencies did not differ between HCV patients and normal healthy subjects or between patient groups when compared according to the therapeutic response. Moreover, the presence of an IL-18 SNP was not associated with histological disease severity. We conclude that the presence of the IL-18 SNP rs1946518 does not affect the outcome of chronic HCV-4 treatment in Egyptian patients. CONCLUSIONS: The IL-18 SNP rs1946518 does not affect response to treatment in chronic HCV-4 patients.
