The Effect of Ginger Supplementation and EnduranceTraining on Serum Levels of IL-1α and TNF-α
Ali Reza Barari ,
Volume 10, Issue 4 (7-2016)
Abstract

ABSTRACT

        Background and Objective: Exercise training and supplementation have different effects on the immune system. The aim of the present study was to evaluate the effect of ginger supplementation and endurance training on serum levels of Interleukin 1 alpha (IL1α) and tumour necrosis factor α (TNFα) in untrained young women.

        Methods: The study was performed on 32 untrained young women with mean age of 30±2 years from city of Abbas Abad, in 2014. The participants were randomly assigned into four groups of endurance training (E), endurance training and ginger supplementation (EG), ginger supplementation (G) and control (C). Endurance training was performed at 60-70% heart rate reserve for six weeks, three times a week, and for 60 minutes per session. Daily supplementation with 10 mg/Kg/day of ginger extract was carried out. T-test and ANOVA were used to evaluate the effect of independent variables, and make comparisons between the groups.

          Results: The mean level of IL-1α decreased significantly after the training period in the G and EG groups. There were significant differences between E and EG groups and EG and C groups. The results of intergroup comparison showed that the mean levels of TNFα decreased significantly after the training in the E, G and EG groups. There were significant differences between E and EG groups, E and G groups, EG and C groups, and G and C groups.

         Conclusion: Ginger consumption and adaptation to endurance training can counteract the negative effects on immune function and stability of mast cell membrane.

          Keywords: Endurance Training, Ginger, IL-1alpha and TNF-alpha.

Background: Research has shown that the extract of some plants has an effective protective effect on liver cells against toxins and oxidants. In this research, the effect of hydroalcoholic extract of ginger against hepatotoxicity caused by doxorubicin (Dox) in adult male rats was investigated.
Methods: In this experimental study, 63 adult male rats were divided into 7 groups (n = 9 per group). The experimental treatments included the control and placebo groups without the use of medicines, experimental group I that received Dox at a dose of 20 mg/kg, experimental groups II and III with 300 and 600 mg/kg of ginger hydroalcoholic extract, and experimental groups IV and V that received 20 mg/kg Dox + 300 and 600 mg/kg of ginger hydroalcoholic extract, respectively. After the end of the test period, serum levels of total bilirubin and direct bilirubin were measured. In addition, the histological changes in the liver were examined after hematoxylin and eosin (H&E) staining.
Results: Serum levels of total bilirubin and direct bilirubin in the Dox group showed a significant increase compared to the control group. In contrast, serum levels of total bilirubin and direct bilirubin in Dox + ZIN 600 and Dox + ZIN 300  had a significant reduction compared to the Dox group (P < 0.05). Ginger extract prevented apoptosis and Dox-induced liver tissue damage in dose-dependent designs.
Conclusion: The hydroalcoholic extract of ginger improves the changes of serum bilirubin and liver tissue after receiving Dox due to its antioxidant compounds.
