“…Therefore, as food additive antioxidant potential of honey can play a positive role to overcome human health issues. Many methods for determining the antioxidative activity in honey have been used such as determination of active oxygen species, their radical scavenging ability [Gheldof & Engeseth, 2002], the 2,2-diphenyl-2-picrylhydrazil (DPPH) antioxidant content [Chen et al, 2000] and enzymatic and non-enzymatic measurements of lipid peroxidation inhibition [Chen et al, 2000;McKibben & Engeseth, 2002;Nagai et al, 2001]. The selection of honey samples with various altitude origins in this study was based on the assumption that varying total phenol content and antioxidant capacity is expected for honey produced from diverse fl oral sources having different geographic regions of Himalayan foothills to the plains of Terai region.…”

Twenty two multifl oral honey samples representing central western parts of Nepal were examined spectrophotometrically for their antioxidant properties and total phenol content. The modifi ed Folin-Ciocalteu method was used to determine total phenol content and 2,2-diphenyl-1-picrylhydrazyl radicals (DPPH • ) assay for antiradical activity. In all samples, physicochemical parameters like moisture, reducing sugar, sucrose, ash, free acidity and water insoluble matter were also measured according to harmonized methods of the International Honey Commission (IHC). The results of physicochemical analysis showed that all the values, except for moisture of a small number of high altitude honey samples, are in good agreement with the current Nepalese standard. The total phenolic contents of honey, collected from high and low altitude, ranged from 154.87 to 41.90 mg gallic acid equivalent (GAE/100 g) respectively, at corresponding antiradical activity using DPPH• expressed as percent inhibition of 76.66% and 25.69%. The IC 50 values of selected high altitude honey samples ranged from 56 to 72 mg/mL. The total antioxidant properties were correlated (P<0.01) between total phenol content and antiradical activity (r=0.992). The obtained results demonstrate that the Nepalese honey collected from high altitude region contained more antioxidants than honey of low altitude region.

Open Access Research Articleactivity is through modification in bone turnover which occurs through two fundamentally different processes, i.e. modeling and remodeling with the activities of osteoblast and osteoclast cells in the mechanisms of bone formation and bone resorption [3]. A number of biochemical assays have been described for measuring serum and urinary concentration of markers of bone metabolism [4] that allow a good estimation of bone metabolic processes and have been established as useful parameters in assessing changes in bone turnover. To date, the mechanisms by which combined exercise and dietary intake lead to changes in bone metabolism are not fully understood.Nutritional supplementation is another main factor associated with bone health and development. Aoe et al. [5] reported that as compared to drugs that have a rapid effect, administration of nutrients related to bone metabolism is relatively safe and inexpensive. To date, the effects of different types of supplementation such as calcium, vitamin D, milk, soy and soy protein on bone mass, turnover and mineral density have been reported [6][7][8][9]. One of the nutrients that has long tradition of use within various medical systems and prescribed for variety of uses from ancient time is honey. Ariefdjohan et al. [10] reported that honey has the potential to increase calcium absorption after 2 days of acute feeding in rats. In addition, Hussain et al. [11] reported that honey has similar effects with hormone replacement therapy on bone densitometry in postmenopausal women. Therefore, it was hypothesized that honey may play a role in increasing bone health.Tualang honey is a wild, multi floral honey produced by Apis dorsata bees that form hives on the branches of giant trees named Tualang in the Malaysian rainforest, and it has been reported recently that ovariectomized rats that received Tualang honey showed greater improvements in trabecular bone structure than rats receiving calcium [12], implying the beneficial effects of Tualang honey supplementation on bone. Nevertheless to date, administration of Tualang honey in combination with exercise on bone health and antioxidant status in rats has not been investigated, thus the present study was proposed. AbstractPurpose: To investigate the effects of combined jumping exercise and honey supplementation on bone metabolism and antioxidant status in female rats.

Abstract:Background: Preeclampsia is associated with impaired antioxidant defense that results in maternofetal complications. In addition to antioxidant defi ciency, hemolytic disorder has also been observed in preeclamptic mother.Methods: This study aims in analyzing the fetal complications using cord blood RBC (red blood cell); further the antihemolytic and antioxidant effi ciency of two common probiotic yeasts Monascus purpureus and Saccharomyces cerevisiae in preeclamptic and normotensive RBCs were assessed.Results: There was a signifi cant decrease in the antioxidant status (p<0.05) with increased oxidative stress, nitrative stress (p<0.05) and hemolysis (p<0.001) in preeclamptic RBC comparatively. M. purpureus demonstrated a highly signifi cant reactive oxygen radical scavenging activity (p<0.001) whereas S. cerevisiae exhibited a highly signifi cant nitric oxide radical scavenging activity (p<0.001). It was noted that oxidative stress hemolysis was decreased with increased antioxidant level in cord blood RBC from both samples after incubation with both yeasts in a similar manner. The antihemolytic property of M. purpureus and S. cerevisiae suggests that S. cerevisiae functions effi ciently with increasing stress. Conclusion: This study demonstrates for the fi rst time that despite their differential scavenging activities, a diet rich in M. purpureus and S. cerevisiae could equally serve as a good natural supplement to alleviate the stress status in the preeclamptic fetus (Tab. 4, Fig. 1, Ref. 39).
