Abstract
History and Objectives: Considering the high cost of mechanical treatment of wastewater and the necessity to investigate more economical methods, specially the ones involving natural treatment processes, a study on efficiency of integrated stabilization pond (ISP) was conducted in Shoosh Sewage Treatment Plant during 1999. Materials and Methods: This ISP experimental study was conducted during three seasons with two types of raw sewage feeding. The system consists of an anaerobic pond in combination with facultative pond in series with a high rate and a maturation samples from inflow and effluent were taken on weekly basis and COD, BOD5, TSS, total nitrogen and total phosphorous were checked, the resulting reduction in mentioned parameters formed the basis of a statistical evaluation. Results: Pollutants reduction was higher in spring compared with summer and fall. BOD5 with 89% reduction showed the highest and total phosphorous with 60% showed the lowest reduction levels during the said period. The level of sewage pollutant reduction during three stages of the study shows that the anaerobic pond in combination with facultative pond registed the highest percentage of pollutant removal. Conclusion: ISP systems are effective in treatment of sewage. Up flow of sewage in fermentation pit has a positive effect on the system efficiency and shows the fermentation pits considerable role in facultative ponds. Since there is little available experience about ISP in Iran, more investigation on the subject is recommended.

Abstract
Background: Factors such as exercises training and taking antioxidant supplements can moderate or increase apoptosis. Therefore, this present study aimed to the effect of endurance training and vitamin C consumption in the conditions of air pollution on the expression of apoptotic proteins BAX and Bcl-2 in the brain of male Wistar rats.
Materials and Methods: In this experimental study, 30 Wistar rats were randomly divided into five groups: 1) polluted air control, 2) supplement, 3) training, 4) training+supplement, and 5) healthy air control .Rats trained in polluted air were maintained in a special chamber to simulate polluted air and performed endurance training protocol .Vitamin C supplement groups received the supplement at a dose of 20 mg/kg. Data analysis was done through One-Way-ANOVA and Tukey's post-hoc tests in SPSS version 26 software.
Results: There is a significant difference in BAX and BCL-2 protein gene expression between the groups (P≤0.0001). This significant difference was the increase in BAX protein expression in the training+supplement group as well as the healthy air control group compared to other groups (P≤0.05). In the training and supplement groups were seen a decrease in BCL-2 protein expression compared to the control group (polluted and healthy) (P≤0.05).
Conclusion: Considering the increase in BAX and decrease in BCL-2 expression, it is possible that training in polluted air can lead to cell damage related to apoptosis. Also, the use of vitamin C supplement alone or together with training cannot modulate the apoptosis of brain cells.
