RESUMO
ABSTRACT Objective: Dyspepsia, one of the most commonly seen symptoms, can be due to organic dyspepsia (OD) or functional dyspepsia (FD). The aim of this study is to evaluate neutrophil-tolymphocyte ratio (NLR) for the predictability of OD due to peptic ulcer disease (PUD) and gastric cancer (GC). Methods: We investigated retrospectively the patients with dyspepsia who underwent endos-copy. The study included 119 patients with OD (41 patients with biopsy-proven GC and 78 patients with PUD) and 100 patients with FD diagnosed. Results: The NLR among the patients with GC and PUD was significantly higher than FD subject (p < 0.001 each). The NLR in patients with GC was also significantly higher than that in patients with PUD (p < 0.005). When OD was compared with FD, NLR and white blood cell were statistically significantly higher (p < 0.001 and p < 0.05 respectively). The best predictive cut-off value of NLR was 1.72 with a specificity of 63% and a sensitivity of 66% for OD, on receiver-operating characteristic curve analysis. Conclusion: Neutrophil-to-lymphocyte ratio was higher in patients with OD compared with those with FD, and even higher in patients with GC. Our findings suggest that NLR should be calculated in patients with dyspepsia and patients with high levels of NLR should undergo endoscopy.
RESUMO
Objectives Sumac (Rhus coriaria L.) is widely used spice which has several properties such as antioxidant, anti-inflammatory and antimicrobial. The purpose of this animal study was to evaluate the effects of sumac extract on levels of receptor activator of nuclear factor-kappa B ligand (RANKL), osteoprotegerin (OPG) expression, serum oxidative status, and alveolar bone loss in experimental periodontitis. Material and Methods Twenty-four Wistar rats were separated into three groups: non-ligated (NL, n=8), ligature only (LO, n=8), and ligature and treated with sumac extract (S, n=8) (20 mg/kg per day for 11 days). A 4/0 silk suture was placed around the mandibular right first molars subgingivally; after 11 days, the rats were sacrificed, and alveolar bone loss was histometrically measured. The detection of RANKL and OPG were immunohistochemically performed. Levels of serum total antioxidant status (TAS)/total oxidant status (TOS), and oxidative stress index (OSI) were also analyzed. Results Alveolar bone loss was significantly greater in the LO group compared to the S and NL groups (p<0.05). The number of inflammatory cell infiltrate (ICI) and osteoclasts in the LO group was significantly higher than that of the NL and S groups (p<0.05). The number of osteoblasts in the LO and S groups was significantly higher than that of the NL group (p<0.05). There were significantly more RANKL-positive cells in the LO group than in the S and NL groups (p<0.05). OPG-positive cells were higher in S group than in LO and NL groups (p<0.05). TOS and OSI levels were significantly reduced in S group compared to LO group (P<0.05) and TAS levels were similar in S and NL group (p>0.05). Conclusions The present study showed that systemic administration of sumac extract may reduce alveolar bone loss by affecting RANKL/OPG balance, TOS and OSI levels in periodontal disease in rats. .
