The treatments of this experiment were consisted of three levels of nano-iron chelate (0, 1 and 2 g.L-1) and four levels of nano-potassium chelate (0, 2, 3 and 4 g.L-1) fertilizer.Results: The interaction of nano-iron and potassium chelated fertilizer treatments had a significant effect on the seed yield (P<0.01) and shoot dry weight (P<0.05). The independent effect of nano-iron and potassium chelated fertilizer were significant on themost traits (P<0.01), number of seeds per plant, and yield of mucilage (P<0.05). Interaction of 2 g.L-1 of nano-iron and 3 g.L-1 of potassium chelate fertilizer treatments, and also their independent effects had the most impact on the measured traits, especially yield of shoot dry weight, seed yield, mucilage content and yield of mucilage.Conclusion: According to the results, the use of nano-iron and potassium chelate fertilizer had positive effects on the efficiency of psyllium.

Background: It has been reported that strenuous acute exercise induces the oxidative stress in active muscles and organism. However, exercise-induced oxidative stress may reduce by supplementation with antioxidants.Objective: The present study was conducted to determine the effects of short-term ginseng supplementation on malondialdehyde (MDA) and superoxide dismutase (SOD) activity in young athletes after exhaustive aerobic exercise.Methods: Twenty young male boxers athletes in semi-experimental study randomly were divided into two placebo and supplement groups. Subjects in supplement group consumed 2gr of ginseng capsules daily for one week, whiles other group received the same amount of placebo (2gr of dextrose). After seven days of supplementation all subjects of both groups underwent in an exhaustive aerobic exercise test that performed on treadmill. Venous blood samples were collected in four phases; 1) before supplementation 2) immediately before of exercise 3) immediately after and 4) 24 h after exercise.Results: The results of this research indicated that the range change of MDA significantly higher in placebo versus to ginseng group at immediately and 24 hours after aerobic exercise (P=0.001). Moreover, SOD enzyme activity significantly increase in supplement group compared to the placebo group after exhaustive exercise (P>0.05).Conclusion: In general it can be said that short-term ginseng supplementation inhabits aerobic exercise- induced oxidative stress by decreasing the levels of MDA and increasing of SOD activity as an antioxidant enzyme in young athletes, and therefore it can be prevent of free radicals damaging effects.

Secretion of pituitary-gonad axis hormones may affected by the pepper.Objective: This study aimed to investigate the possible effects of black and red pepper on serum levels of Luteinizing hormone (LH), Follicle-stimulating hormone (FSH) and testosterone hormone was performed.Methods: 21 male NMRI mice were divided into three groups (n=7), consisting of a control group and two treatment groups receiving red pepper and black pepper, respectively. Treated groups received pepper powder mixed with pellet food at a ratio of 6.6% for one month. At the end of treatment, animals were anesthetized with chloroform and blood samples were collected from the heart directly. After separating the serum, LH, FSH and testosterone hormones were measured by ELISA method. Data statically evaluation using one-way ANOVA followed by Tukey test for ANOVA was performed and calculated.Results: Red pepper increased testosterone (P<0.01). Red pepper and Black pepper increased FSH (P<0.001) and P<0.01 respectively) and have no effect on the LH levels. Hematocrit levels also increased in the treatment groups (P<0.001).Conclusion: Oral intakes of red and black peppers powder have increasing impact on FSH and testosterone hormones. Therefore, these peppers may have androgenic properties. Increases in hematocrit may be the result of an increase in testosterone.

Background: Hypertension is a health problem and alternative medicine is offered for its controlling.Objective: Nutritional effects of Lavandula angustifolia L. (lavender) oil on high blood pressure (BP), and histological changes of the aorta in rat has been investigated in this study.Methods: Therty five male wistar rats were divided into 5 groups; normal, hypertensive and control. Hypertension was induced by daily L-NAME administration in drinking water for 6 weeks and lavender oil (500 mg/kg) or its vehicle was given orally simultaneously. After basal BP measurement, lavender (50 mg/kg, iv) was injected in control groups. Histological evaluation of the thoracic aorta included staining with hematoxylin-eosin and orcein methods.Results: Hypertension induction increased mean arterial BP from 106 to 177 mm Hg and lavender treatment reduced it to 140 mm Hg (P<0.001). Lavender had no effect on normal rats. Intravenous injection of lavender reduced BP about 75% in normotensive and hypertensive rats (P<0.001). Hypertension induction increased cross-section area, aorta and media thickness, and reduced elastic lamina thickness (P<0.001). Lavender treatment reduced cross-section area of the aorta and media thickness, and increased elastic lamina thickness (P<0.05). Hypertension and treatment had no effect on advanthia and elastic lamina numbers.Conclusion: Nutritional lavender oil prevented BP increases and pathological changes of the aorta in hypertensive rats. It seems lavender oil is beneficial for prophylaxis of hypertension.
