Protective effects of boron and vitamin E on ethylene glycol-induced renal crystal calcium deposition in rat
Objectives. Kidney stone disease is a common form of renal disease. Antioxidants, such as vitamin E (Vit E) and boron, are substances that reduce the damage caused by oxidation. Methods. Adult male rats were divided into 5 groups (n=6). In group 1, rats received standard food and water for 28 days (control group); in group 2, standard rodent food and water with 0.75 ethylene glycol/d (dissolved in drinking water) (EG Group); in group 3, similar to group 2, with 3 mg of boron/d (dissolved in water) (EG+B Group); in group 4, similar to group 2, with 200 IU of vitamin E injected intraperitoneally on the fi rst day and the 14th day, (EG+Vit E Group); in group 5, mix of groups 3 and 4, respectively (EG+B+Vit E Group). Results. Kidney sections showed that crystals in the EG group increased signifi cantly in comparison with the control group. Crystal calcium deposition score in groups of EG+B (160), EG+Vit E, and EG+B+Vit E showed a significant decrease compared to EG group. Measurement of the renal tubules area and renal tubular epithelial histological score showed the highest signifi cant dilation in the EG group. Tubular dilation in the EG+B+Vit E group decreased compared to the EG+B and EG+Vit E groups. Conclusions. Efficient effect of boron and Vit E supplements, separately and in combination, has a complimentary effect in protection against the formation of kidney stones, probably by decreasing oxidative stress. � 2016, De Gruyter Open Ltd.

Whole body vibration is a safe exercise training method and induces no impaired alterations on rat plasma parameters
Whole body vibration (WBV) has been regarded as an exercise training method and as a non-pharmacological supportive treatment option appearing to be efficient for chronic disease conditions, such as bone disorders and cardio-respiratory fitness. Since, data on the safety and efficacy of vibration on plasma parameters are lacking, therefore, it was decided to assess the effects of WBV on the plasma parameters in adult male Wistar rat model.Methods:
Male Wistar rats, weighing 140–180 g, were divided into control and the vibration group. Vibration
training consisted of vertical sinusoidal whole body vibration for 8 weeks, followed by blood collection.
Results:
The vibrated rats weighed more than the control group (approximately 14% more). Plasma CK, E2 and
IL-6 levels were significantly higher in the vibration group compared with the controls. The mean of Vit. D level was
15% higher; hsCRP level was 11% lower and IL-6 level was 32% higher in the vibration group. No difference was
observed for other selected plasma parameters.
Discussion:
The potential effects of physiological responses of WBV on several physiological systems are
without deteriorations in plasma parameters
