Purpose: To explore the feasibility of combined assay with serum tumor marker and low dose CT on the early diagnosis of lung cancer. Method: 60 newly diagnosed lung cancer patients (lung cancer group), 60 benign lung disease patients (benign group) and 60 healthy subjects (health group) were included. All participants were diagnosed by serum tumor marker and low dose CT. Result: There are few n...

Treatment with amiodarone, a commonly prescribed antidysrhythmic agent, is associated with pulmonary fibrosis (PF) which is a commonly progressive and untreatable dieases. Caffeic acid phenethyl ester (CAPE) is a phenolic antioxidant and an active anti-inflammatory, anticancer, antimicrobial and antioxidant component of propolis (bee glue; a resinous hive product collected by honey bees). In th...

background: the dosimetric parameters required in lung cancer radiation therapy are taken from a homogeneous water phantom; however, during treatment, the expected results are being affected because of its inhomogeneity. therefore, it becomes necessary to quantify these deviations. objective: the present study has been undertaken to find out inter- and intra- lung density variations and its dos...

Objective(s): To investigate the protective effect of S-nitrosoglutathione (SNG) pretreatment on acute lung injury (ALI) in septic rats. Materials and Methods: We constructed a rat model of sepsis by cecal ligation and perforation (CLP), and randomly divided into Sham, CLP, and CLP+SNG (0.25 and 0.5 mg/kg) groups. We used H&E; staining an...

PURPOSE To estimate the radiation-related lung cancer risks associated with annual low-dose computed tomographic (CT) lung screening in adult smokers and former smokers, and to establish a baseline risk that the potential benefits of such screening should exceed. MATERIALS AND METHODS The estimated lung radiation dose from low-dose CT lung examinations corresponds to a dose range for which th...

BACKGROUND Numerous studies have examined the association between heavy metal contamination (including arsenic [As], cadmium [Cd], chromium [Cr], copper [Cu], mercury [Hg], nickel [Ni], lead [Pb], and zinc [Zn]) and lung cancer. However, data from previous studies on pathological cell types are limited, particularly regarding exposure to low-dose soil heavy metal contamination. The purpose of t...

Background: The purpose of this study is to fabricate inexpensive in-house low cost homogeneous and heterogeneous human equivalent thorax phantom and assess the dose accuracy of the Treatment Planning Systems (TPS) calculated values for different lung treatment dosimetery. It is compared with Thermoluminescent Dosimeter (TLD) measurement. Materials and Methods: Homogeneous and heterogeneous tho...

Introduction: The proton beam produced in particle accelerators has an appropriate therapeutic potential. In this research, proton therapy of breast cancer is simulated using the MCNPX code in a MIRD phantom, also the contribution of scattered neutron dose during the proton therapy were calculated for the Heart, Lung and Liver.   Materials and Methods: For si...

Delivery of drug aerosols to the lungs of ventilated neonates by metered dose inhaler and spacer (Aerochamber) and ultrasonic nebuliser (Pentasonic) was assessed using sodium cromoglycate. The mean proportion of a known intratracheal dose of sodium cromoglycate excreted in the urine of four intubated infants was 37.5%. After assuming that 38% of the sodium cromoglycate aerosol reaching the neon...
