Virgin Coconut Oil

Virgin coconut oil (VCO) was found to have antioxidant property due to its high polyphenol content. The aim of this study was to investigate the effect of the virgin coconut oil on lipid peroxidation in the bone of an osteoporotic rat model. Normal female Sprague-Dawley rats aged 3 months old were randomly divided into 4 groups, with 8 rats in each group: baseline, sham, ovariectomised (OVX) control group, and OVX given 8% VCO in the diet for six weeks. The oxidative status of the bone was assessed by measuring the index of lipid peroxidation, which is malondialdehyde (MDA) concentration, as well as the endogenous antioxidant enzymes glutathione peroxidase (GPX) and superoxide dismutase (SOD) in the tibia at the end of the study. The results showed that there was a significant decrease in MDA levels in the OVX-VCO group compared to control group. Ovariectomised rats treated with VCO also had significantly higher GPX concentration. The SOD level seemed to be increased in the OVX-VCO group compared to OVX-control group. In conclusion, VCO prevented lipid peroxidation and increased the antioxidant enzymes in the osteoporotic rat model.

This study shows the antioxidant effect of a dietary hemp seed diet rich in ω-6 polyunsaturated fatty acid (PUFA) on oxidative status in sows during late gestation and lactation and their offspring. Ten pregnant sows were divided into two groups and fed either a control diet (CD) or a hemp diet (HD) containing 2% hemp seed meal for a period of 10 days before farrowing and 5% throughout the lactation period (21 d). After farrowing, 16 of their resulting piglets were divided into two groups: control group CD (eight piglets derived from control sows) and HD group (eight piglets derived from HD sows), respectively. Blood collected from sows and piglets at day 1, 7 and 21 was used for the measurement of antioxidant enzymes (catalase (CAT), superoxide dismutase (SOD), glutathione (GPx)), nitric oxide production (NO), lipid peroxidation (thiobarbituric acid reactive substances—TBARS), reactive oxygen species (ROS) generation and total antioxidant capacity (TAC) in plasma. The results showed a significant improvement in the oxidative status of sows fed HD throughout lactation compared with CD. Similarly, in piglets, HD positively influenced the activities of antioxidant enzymes, TAC and NO levels and significantly decreased lipid peroxidation in plasma until weaning, in comparison with the CD group. This study suggests the potential of hemp seed diet to improve the overall antioxidant status of the lactating sows and their progeny.

AbstractIntroduction: Wounds are a breakdown of tissue integrity / continuity that can lead to infection. Virgin Coconut Oil is a processed coconut product made by processing fresh coconut flesh at low temperature and has a high nutritional content. Ozone therapy is an alternative therapy that has disinfectant properties and can induce strong oxidative stress. Methods: This study was conducted on 50 Sprague-Dawley rats that had injuries. We performed full thickness wounds and administered ozonated doses of VCO to mice. We looked at shrinkage of wounds and TGF Beta levels in mice. Assessment was carried out on day 7 and day 14 to assess the wound and TGF-beta immunohistochemically. Results: There was a significant difference in the wound shrinkage variable between the negative control group and the group that received VCO offerings both on day 7 and day 14. We also found a significant difference in the TGF-beta variable between the negative control group and the group that received VCO offerings both on day 7 and day 14. Conclusion: The administration of ozonated virgin coconut oil was effective in increasing the expression of TGF-? in the full thickness defect of Sprague Dawley rats and was effective in increasing the reduction in wound size in the full thickness defect of Sprague Dawley rats.

Introduction: The role of virgin coconut oil in the treatment of allergic rhinitis is controversial. Thus, the aim of the present study is to determine the effects of virgin coconut oil ingestion, in addition to standard medications, on allergic rhinitis. We also studied the side effects of consumption of virgin coconut oil. Methods: Fifty two subjects were equally divided into test and control groups. All subjects received a daily dose of 10mg of loratadine for 28 days. The test group was given 10ml of virgin coconut oil three times a day in addition to loratadine. The symptoms of allergic rhinitis were scored at the beginning and end of the study. Results:, the symptom score were divided into nasal and non-nasal symptom scores. Sneezing score showed a significant difference, however the score was more in control group than test group, indicating that improvement in symptom was more in control group. The rest of the nasal symptom and non-nasal symptom score showed no significant difference between test and control groups. Approximately 58% of the test subjects developed side effects from consumption of virgin coconut oil, mainly gastrointestinal side effects. Conclusion: In the present study, ingestion of virgin coconut oil does not improve the overall and individual symptoms of allergic rhinitis, furthermore it has side effects.

Cisplatin-induced nephrotoxicity is associated with an increase in lipid peroxidation and oxygen free radicals in rat kidneys. In this study, the effects of desferrioxamine were compared to vitamin C and E on cisplatin-induced lipid peroxidation and antioxidant enzyme activities in rat kidneys. Rats were divided into five groups, with 15 Wistar rats in each group. In the control group, rats received 1 mL/100 g isotonic saline solution intraperitoneally (i.p.). In Group II, 10 mg/kg cisplatin i.p. was injected to rats. Thirty minutes before the same dosage of cisplatin administration, 100 mg/kg i.p. vitamin C or E was given to rats in groups III and IV, respectively. Rats in Group V received 250 mg/kg desferrioxamine i.p., before the same dose of cisplatin administration. All rats were killed by cervical dislocation after 72 hours. The kidneys were immediately removed and washed in cold saline. Spectrophotometric method was used for all analyses. While catalase, glutathione reductase (GR), and super oxide dismutase (SOD) levels were found to be significantly decreased (P B < 0.001), malondialdehyde (MDA) (P < 0.05) and hydrogen peroxide (H2O2) (P < 0.001) levels were significantly increased in the cisplatin group when compared to the controls. MDA levels were decreased by desferrioxamine (P < 0.005) as well as vitamin C and E (P < 0.05 and P < 0.001, respectively). These three compounds induced a significant increase in SOD levels (P B < 0.05), but only in the vitamin C group, were SOD levels not significantly different than the levels of the controls (P > 0.05). In the desferrioxamine (P < 0.05), vitamin C and E groups (P < 0.001 for both), the cisplatin elevated H2O2 levels were decreased. None of these drugs had any effect on GR and catalase levels (P > 0.05). Desferrioxamine is useful to prevent cisplatin-induced lipid peroxidation, however, vitamin C and E are more effective on antioxidant enzymes than desferrioxamine.

Experimental studies examining the effects of regular exercise on cardiac responses to ischemia and reperfusion (I/R) are limited. Therefore, these experiments examined the effects of endurance exercise training on myocardial biochemical and physiological responses during in vivo I/R. Female Sprague-Dawley rats (4 mo old) were randomly assigned to either a sedentary control group or to an exercise training group. After a 10-wk endurance exercise training program, animals were anesthetized and mechanically ventilated, and the chest was opened by thoracotomy. Coronary occlusion was achieved by a ligature around the left coronary artery; occlusion was maintained for 20 min, followed by a 10-min period of reperfusion. Compared with untrained, exercise-trained animals maintained higher ( P < 0.05) peak systolic blood pressure throughout I/R. Training resulted in a significant ( P < 0.05) increase in ventricular nonprotein thiols, heat shock protein (HSP) 72, and the activities of superoxide dismutase (SOD), phosphofructokinase (PFK), and lactate dehydrogenase. Furthermore, compared with untrained controls, left ventricles from trained animals exhibited lower levels ( P < 0.05) of lipid peroxidation after I/R. These data demonstrate that endurance exercise training improves myocardial contractile performance and reduces lipid peroxidation during I/R in the rat in vivo. It appears likely that the improvement in the myocardial responses to I/R was related to training-induced increases in nonprotein thiols, HSP72, and the activities of SOD and PFK in the myocardium.

Chronic kidney failure is a public health problem throughout the world, and the number of sufferers is increasing. Chronic kidney failure can cause clinical symptoms in various body systems, one of which is a disorder in the skin that becomes dry (uremic). This study aimed to examine the effect of Virgin Coconut Oil (VCO) on the skin moisture among uremic patients undergoing hemodialysis. This type of research is a quasi-experiment with pre-test and post-test equivalent control group. The study was conducted at the Regional General Hospital, Dr. RM. Djoelham Binjai. The study population was 80 people, divided into 2 sample groups of 40 people each. The results showed that there was a significant effect of skin moisture on the intervention group before and after being given Virgin Coconut Oil, p = 0.000<0.05; There was a significant effect of skin moisture in the control group before and after lotion (post-test), p = 0.000<0.05. There is no need for special emulsions such as VCO to moisturize the skin in uremic patients undergoing hemodialysis because using ordinary lotions can moisturize the skin. It must be used regularly, twice a day after bathing. The lotion used must also be a lotion that does not contain mercury and chemicals that can harm the skin. To increase the skin's moisture becomes normal, giving lotion is better than VCO because by providing lotion, more skin becomes normal, while using VCO, the skin becomes more oily. It is recommended to health workers (doctors, nurses) to practice correctly and appropriately how to administer Virgin Coconut Oil (VCO) to uremic patients undergoing hemodialysis to be done at home

Objective To examine the possible impact of moxibustion on the serum proteome of the collagen-induced arthritis (CIA) rat model. Materials and Methods Thirty-six male Sprague-Dawley rats were included in this experiment. The CIA animal model was prepared by injection of type II bovine collagen in Freund's adjuvant on the first and seventh day. The 36 rats were randomly divided into two groups: the untreated CIA group (control), and the CIA plus treatment with moxibustion (CIA+moxi) group. Moxibustion was administered daily at ST36 and BL23 for 7, 14 or 21 days (n=12 rats each). Arthritis score was used to assess the severity of arthritis. At the end of each 7 day treatment, blood samples from the control group and the CIA+moxi group were collected. After removal of high abundance proteins from serum samples, two-dimensional gel combined with matrix-assisted laser desorption ionisation time-of-flight MS/MS (MALDI-TOF-MS/MS) techniques were performed to examine serum protein expression patterns of the CIA rat model with and without moxibustion treatment. In addition, the relevant proteins were further analysed with the use of bioinformatics analysis. Results Moxibustion significantly decreased arthritis severity in the rats in the CIA+moxi group, when compared with the rats in the CIA group 35 days after the first immunisation (p=0.001). Seventeen protein spots which changed >1.33 or <0.77 at p<0.05 using Bonferonni correction for multiple testing were found to be common to all three comparisons, and these proteins were used for classification of functions using the Gene Ontology method. Consequently, with the use of the Ingenuity Pathway Analysis, the top canonical pathways and a predicted proteomic network related to the moxibustion effect of CIA were established. Conclusions Using the proteomics technique, we have identified novel candidate proteins that may be involved in the mechanisms of action underlying the beneficial effects of moxibustion in rats with CIA. Our findings suggest that immune responses and metabolic processes may be involved in mediating the effects of moxibustion. Moreover, periodxiredoxin I (PRDX1) and inositol 1,4,5-triphosphate receptor (IP3R) may be potential targets.

In this study the effect of butylated hydroxyanisole (BHA), a phenolic antioxidantused in food on Ferric‐Nitrilotriacetate (Fe–NTA) induced nephrotoxicity is reported. Fe‐NTA (9 mg Fe/kg body weight, intraperitoneally) treatment enhanced the renal microsomal lipid peroxidation and hydrogen peroxide generation to ~2‐2.5 folds compared to saline‐treated control and glutathione levels and the activities of antioxidant enzymes decreased to a range of 2–2.5 fold in kidney. These changes were reversed significantly in animals receiving a pretreatment of BHA. Pretreatment with BHA prior to Fe‐ NTA treatment reduced microsomal lipid peroxidation and hydrogen peroxide generation to 1.3‐1.5 fold compared to control group and glutathione and the activities of antioxidant enzymes increased to a range of 1.5‐2 folds in kidney. Fe‐NTA administration enhanced value of blood urea nitrogen and creatinine to 3.7 and 2.5 fold respectively as compared to their corresponding control group. Administration of Fe‐NTA to rats receiving a pretreatment of BHA led to a significant diminution in both of these values. The results indicate that BHA is a potent chemopreventive agent and suppresses Fe‐NTA induced nephrotoxicity in rats.
