Abstract Backgrond: Pharmaceutical products, particularly antibiotics such pollutants are evolving due to the cumulative effects, adverse effects and drug resistance is a major concern in the control environment. The purpose of this work is to investigate the feasibility and potential of iron nanoparticles in the aqueous solution being removed antibiotics. Materials and Methods: In this study, the performance activated persulfate with zero-valent Zinc nanoparticles in the presence of ultrasound in the analysis of antibiotics was investigated. The effect of process parameters such as pH of the solution (2.97-10.53), concentration Potassium persulfate (194.33-1200mg/l) and the zero-valent zinc (12.73-147.27mg/l) in reaction time 0-180 min using a batch chamber ultrasonic were studied. A statistical procedure was used to optimize the parameters of the RSM model. Antibiotics are measured based on COD vials and DR-5000 spectrophotometer was used. Results: The results showed that the initial pH of the solution is the most important influential parameters. The addition of potassium persulfate and zero valent zinc in the samples was enhanced performance. Optimum efficiency achieved in 50 mg/l concentration antibiotics, potassium persulfate 1200 mg/l, the zero- zinc 120 mg /l, pH 4.5. Conclusion: The results of this study demonstrate acceptable performance persulfate activated process with zero-valent iron and zinc nanoparticles on ultrasound in the presence of antibiotic.

Objectives Constipation is a predominant gastrointestinal problem after the onset of stroke, which may increase intracranial pressure. Treatment of constipation includes using laxatives and fibers, which is associated with complications and limitations. Regarding the effect of probiotics to treat digestive problems, the current study aimed at investigating the effect of probiotics on constipation in the patients with stroke admitted to Intensive Care Unit (ICU).Methods The current randomized clinical trial was conducted on 65 patients with stroke. Patients with nasal-gastric tube and absence of rejection in 3 consecutive days were enrolled to the study. They were randomly divided into 2 groups of intervention (n=33) and control (n=32); the frequency of their bowel movements were measured before the study. Subjects in the intervention group received a probiotic supplement every 12 hours; however, the ones in the control group received the only routine conventional treatment for a week. After a week, all subjects were assessed for the improvement of constipation. Data were analyzed by SAS software version 9.1 using Poisson regression model. Results In the intervention group, the mean number of bowel movements was more than once a day, 1.22, and in the control group it was 0.62 (P<0.0001).Conclusion The current study showed that probiotic supplement consumption increased the frequency of constipation in patients with stroke. Therefore, probiotics can be used to treat constipation in such patients.
