Previous clinical trials using virgin coconut oil (VCO) showed a potential anti-obesity effect, including for human, by reducing the waist circumference. However, there was not discovered any research that examined its anti-obesity effect in relation with gut microbiota parameters as one of current approaches of obesity parameters, for example Firmicutes and Bacteroidetes. This research was conducted to examine the effect of VCO supplementation on the change of Firmicutes and Bacteroidetes in comparison to the anthropometrical parameters. The experiment was done using 14 days obese-induced female Sprague-Dawley rats supplemented with 0.01% w/w and 0.02% w/w VCO for 28 days. The anthropometric data collection consisted of body weight (BW), body mass index (BMI), abdominal circumference (AC), and body length (BL). Ratio changes in –fold increase between Day 28 and Day 0 of Bacteroidetes and Firmicutes were retrieved by using relative quantification normalized against unit mass calculation, using the cycle threshold values from real-time polymerase chain reaction (RT-PCR) method with SYBR Green fluorescence and standard curve derived from tenfold 5 points dilution series of recombinant plasmid for efficiency calculation. VCO supplementation stimulated significant increase on anthropometric parameters on BW and AC (p<0.05), while insignificant changes were shown on Bacteroidetes and Firmicutes ratio with tendency of increasing and decreasing respectfully, with no significance. The result indicated that VCO supplementation in the given doses promoted pro-obesity effect on key anthropometric parameters, while showed potential anti-obesity effect on the gut microbiota parameter. Further researches were needed especially in determining the effective dose to promote the anti-obesity effect of VCO and revealing any possible cellular and molecular mechanisms.

Abstract Metabolic syndrome a lifestyle disease, where diet and gut microbiota play a prodigious role in its initiation and progression. Prophylactic bio-interventions employing probiotics and prebiotics offer an alternate nutritional approach towards attenuating its progression. The present study aimed to evaluate the protective efficacy of a novel synbiotic (L. pentosus GSSK2 + isomalto- oligosaccharides) in comparison to orlistat in an experimental model of metabolic syndrome. It was observed that supplementation of synbiotic for 12 weeks to Sprague Dawley rats fed with high fat diet, ameliorated the anthropometric parameters i.e. weight gain, abdominal circumference, Lee’s index, BMI and visceral fat deposition along with significantly increased fecal Bacteroidetes to Firmicutes ratio, elevated population of Lactobacillus spp., Akkermansia spp., Faecalibacterium spp., Roseburia spp. and decreased Enterobacteriaceae compared with HFD animals. Additionally, synbiotic administration to HFD animals exhibited improved glucose clearance, lipid biomarkers, alleviated oxidative stress, prevented leaky gut phenotype, reduced serum lipopolysaccharides and modulated the inflammatory, lipid and glucose metabolism genes along with restored histomorphology of adipose tissue, colon and liver compared with HFD animals. Taken together, the study highlights the protective potential of synbiotic in comparison with its individual components in ameliorating HFD-induced metabolic complications.

Abstract Background: Now, Skin grafts are one of the therapies of choice in the wound healing process. And this is still developing today. The process of formation fibroblas and the formation of vascular endothelial growth factor have an important role in healing skin graft wounds. Ozonated virgin coconut oil has an important role in wound healing. Objective: To prove the effect of ozonated virgin coconut oil in various doses in increasing number of fibroblas and expression of vascular endothelial growth factor of skin graft wounds. Methods: This study is an experimental study with "Randomized parallel study with controlled group design" on 40 Sprague Dawley rats which are performed an autologous skin graft at the same time. Samples were divided randomly into 8 groups (K1 and K2 = without ozonated VCO), (A1 and A2 = ozonated VCO 50,4 mg/ml), (B1 and B2 = ozonated VCO  103,2 mg/ml), (C1 and C2  = ozonated VCO 204  mg/ml). Evaluation of the amount of fibroblas was done by staining hematoxylin & eosin after the 6th day and the expression of vascular endothelial growth factor  was done by staining immunohistochemistry after the 12th  day after skin graft. Results: Statistical analysis of the amount of fibroblas after the 6th  day was found to be significantly different between the K1 vs A1 group (p = 0.029), K1 vs B1 (p = 0.004), K1 vs C1 (p = 0.000), on the 12th day was found significantly different the amount of fibroblast between K2 vs A2 ( p = 0,029 ), K2 vs B2 ( p = 0,010 ), K2 vs C2 ( p = 0,001 ). The expression of vascular endothelial growth factor on the 6th day was found a significant difference between the K1 vs A1 group (p = 0.024), K1 vs B1 (p = 0.005), K1 vs C1 (p = 0.001), on the 12th day was found significantly different the expression of vascular endothelial growth factor between K2 vs A2 ( p = 0,011 ), K2 vs B2 ( p = 0,036 ), K2 vs C2 ( p = 0,004 ) . Conclusion: Ozonated VCO can increase the amount of fibroblas and expression of vascular endothelial growth factor  in the wound healing process of autologous skin graft in Sprague Dawley rats.

 Objective: Doxorubicin (DOX) is a drug of choice in many cancer therapies. Virgin coconut oil (VCO) is one of nutraceutical which has many biology activities. This current study was carried out to investigate the VCO activity in modulating TCD4+, and TCD8+ cells profile toward rats which induced by DOX.Methods: A total of 15 Sprague-Dawley rats were divided into three groups consisting of five rats each as follows: Group 1, receiving oral saline 10 mL Kg BW (control group); Group 2, receiving oral saline 10 mL/kg BW; and Group 3, receiving VCO 5 mL/kg BW. Group 2 and 3 were administered with DOX intramuscularly at dose 4.67 mg/kg BW at day 1 and 4 to suppressed immune functions.Results: Treatment of VCO 5 mL/kg BW succeeded in reducing a side effect of DOX based on increasing the TCD4+ and TCD8+ blood level.Conclusion: The results reveal that VCO could increase the level of TCD4+ and TCD8+ in rats which induced by DOX.

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.

The objective of this experiment was to determine the effects on mammary carcinogenesis of similar limitations in energy availability either by energy expenditure due to moderate-intensity running (physical activity, PA) or by regulating dietary energy (RE) intake relative to a sedentary control (SC) group that ate ad libitum. A total of 90 female Sprague-Dawley rats were injected with 1-methyl-1-nitrosourea (50 mg/kg) and 7 days thereafter were randomized to either SC, a PA group given free access to a motorized running wheel, or a RE group whose food intake limited growth to the rate observed in PA. Compared with SC, mammary carcinogenesis was inhibited by RE or PA. Cancer incidence, 92.6%, 77.8%, and 66.7% ( P = 0.06), and cancer multiplicity, 3.44, 2.11, and 1.62 cancers/rat ( P = 0.006), in SC, RE, and PA, respectively, were reduced to a similar extent by RE and PA. Histological and Western blot analyses of mammary carcinomas provided evidence that RE and PA induced apoptosis via the mitochondrial pathway, that cell cycle progression was suppressed at the G1/S transition, and that intratumoral blood vessel density was reduced, although it remains to be determined whether PA and RE exert these effects via the same mechanisms.
