Abstract
ABSTRACT
Background and Objectives: Citrus fruits and their constituents especially naringin (NR), a natural predominant flavanone, have a wide range of pharmacological activities without toxicity against cancer cells. The aim of this study was to investigate the anticancer effects of orange peel extract (OPE) and naringin (NR) on esophageal squamous cell carcinoma (ESCC) cells.
Methods: Amount of phenol, flavonoid and antioxidants in OPE was determined using Folin-Ciocalteu procedure, aluminum chloride colorimetric and DPPH assays, respectively. Effects of NR and OPE on viability, wound healing assay and DNA fragmentation using DAPI were investigated. Data were analyzed by ImageJ software and GraphPad Prism 6.0 at significance of 0.05.
Results: Total amount of phenols, flavonoids and 1,1-diphenyl-2-picrylhydrazyl was 2.83, 2.143 and 60.76 g/100g of OPE. Amount of NR in the dried OPE was estimated to be 5.260 (µg/gr) using high-performance liquid chromatography. Treatment of ESCC cells with OPE or NR decreased viability y of cancer cells in a dose-dependent manner. In addition, both OPE and NR were able to decrease cell migration and increase DNA fragmentation.
Conclusion: The findings of our study suggest that OPE and NR have anticancer effects on ESCC cells but the anticancer effects of OPE was better than that of NR alone.
Keywords: Orange peel extract, Naringin, Migration, Esophageal squamous cell carcinoma.

Abstract
Objectives: Although extrapulmonary tuberculosis (EPTB) is a secondary target for national TB control programs, its significance has increased worldwide. In order to study the epidemiology of EPTB in the Northeast of Iran, this survey was conducted.
Methods and Methods: A population-based, retrospective analysis of all cases of EPTB during 2012–2015 reported to the TB Unit of the Golestan was performed. Socioeconomic and environmental variables, sites, admission, mode of diagnosis and outcome status were collected. Data analyzed through SPSS 25.0 by descriptive and analytical statistical methods.
Results: A total of 741 cases of EPTB were included. Patients were mainly female (59.1%), age of 0 to 40 years old (57.6%), less than five years of education (46.7%) and mainly Fars (39.6%). Non-native ethnicities significantly acquired EPTB more than native ethnicities (p<0.001). Mortality rate was 5.1%. Smoking detected more frequently in EPTB patients (p<0.001). HIV status of most EPTB patients (89.3%) were unknown. The most common forms were pleural (30.5%) and lymphadenopathy (22.0%). Cultures and PCR performed in only about 10 percent of EPTB patients in our study.
Conclusions: EPTB was more prevalent in non-native population. Improvement of socioeconomic conditions and screening program may be successful in reducing the problem among immigrant
