Introduction: Paneer-boot, with its antifungal and antibacterial effects, blood sugar and cholesterol-lowering, immune system, and antioxidant activity, has recently received pharmacologists' attention due to its high compatibility. Due to difficult ecological conditions, it can grow in the country's tropical regions such as Sistan and Baluchestan Province .
Materials & Methods: This study was designed in a completely randomized design with four replications under laboratory conditions at Khorasan Razavi Agricultural and Natural Resources Research and Education Center. Concentrations of 0, 2, 4, 6, 8, and 10 bar PEG were used to induce the effect of drought stress on MS medium containing BAP on secondary traits of cheese .
Results: The results showed that the drought stress significantly increased antioxidant enzymes such as catalase, peroxidase, ascorbate peroxidase, proline, phenol, and flavonoid content membrane leakage. On the other hand, it resulted in a significant decrease in the relative humidity content, potassium ion content and potassium to sodium ratio. Also, most of the studied traits had a significant correlation. Conclusion: The results showed that the Paneer-boot plant had acceptable tolerance to induction of drought stress with polyethylene glycol. Enzymatic and non-enzymatic mechanisms had a significant role in reducing the adverse effects of drought stress. On the other hand, drought stress increased some metabolites, such as phenol and flavonoids, which have medicinal uses .

The physical activity as a therapeutic tool is rapidly growing in the diabetic neuropathy. The aim of this study was to evaluate the effect of six weeks endurance training on the; superoxide dismutase (SOD), catalase (CAT), and pain in sensoty roots of spinal cord of rats with diabetic neuropathy. fourty rats (10 w; 230- 260 g) were study sample. Thirty rats, received interperitoneal injection of Sterptozotocin (STZ) solution (45 mg/kg, pH=4.5). Rats ranodmly assigned to three groups: diabetic continous training, diabetic interval training, diabetic control. ten rats were assigned in healthy control group. Training protocol was a six weeks aerobic training with 60- 70% VO2max treadmill run. 48 h after the last training session, the sensory part of spinal cord sampled.

Background: Regarding estrogen role in free radical scavenging, secretion cessation of estrogen in menopause is considered as the source of ROS increase. due to deficiency of estrogen, antioxidant defence system seems to be affected in this phase. The aim of this study was Assay of total antioxidant capacity and superoxide dismutase and catalase activities in menopausal women.
Materials and Methods: This case-control study was performed on 75 postmenopausal women as a case group and 74 volunteer premenopausal women as a control was performed. Serum enzyme activity of catalase, superoxide dismutase and total antioxidant capacity was measured in the fasting state.
Results: The amount of total antioxidant capacity in postmenopausal (11.4±4.4 mM Trolox) compared to the control group (10.3±1.2 mM Trolox) were significantly decreased (p
