Abstract
PURPOSE Dietary fats with an abundance of phytonutrients have garnered public attention beyond fatty acids per se. This study was set to investigate the impact of consuming diets with red palm olein (RPOO), extra virgin coconut oil (EVCO) and extra virgin olive oil (EVOO, as a control) on cardiometabolic risk biomarkers and lipid profile. METHODS We recruited a total of 156 individuals with central obesity, aged 25-45 years, with waist circumference ≥ 90 cm for men and ≥ 80 cm for women in a parallel single-blind 3-arm randomised controlled trial. The participants consumed isocaloric diets (~ 2400 kcal) enriched with respective test fats (RPOO, EVCO or EVOO) for a 12-week duration. RESULTS The mean of the primary outcome plasma high sensitivity C-reactive protein was statistically similar between the three diets after a 12-week intervention. EVOO resulted in significantly lower mean LDL cholesterol compared with RPOO and EVCO, despite similar effects on LDL and HDL cholesterol subfractions. The RPOO diet group showed elevated mean α and β -carotenes levels compared with EVCO and EVOO diet groups (P < 0.05), corresponding with the rich carotenoid content in RPOO. CONCLUSION The three oils, each of which has unique phytonutrient and fatty acid compositions, manifested statistically similar cardiometabolic effects in individuals with central obesity at risk of developing cardiovascular diseases with distinct circulating antioxidant properties. CLINICAL TRIAL REGISTRATION ClinicalTrials.gov (NCT05791370).

Abstract
Alzheimer's disease (AD) is a progressive neurological disorder that affects various cognitive functions, behavior, and personality. AD is thought to be caused by a combination of genetic and environmental factors, including exposure to aluminum (Al). Virgin coconut oil (VCO) may have potential as a natural neuroprotectant against AD. Aim of this study was to determine neuroprotective effects of VCO on Al-induced neurotoxicity in an in vitro AD model. SH-SY5Y cells were initially cultured in normal growth medium and then differentiated by reducing fetal bovine serum content and adding retinoic acid (RA). Later, brain-derived neurotrophic factor (BDNF) was added along with RA. The differentiation process was completed on the seventh day. Study groups (n = 3) were designed as control group, VCO group, Al group, Al-VCO group, Alzheimer model (AD) group, AD + Al-exposed group (AD+Al), AD + VCO applied group (AD + VCO) and AD + Al-exposed + VCO applied group (AD + Al + VCO). Specific markers of AD (hyperphosphorylated Tau protein, amyloid beta 1-40 peptide, and amyloid precursor protein) were measured in all groups. In addition, oxidative stress parameters (total antioxidant capacity, lipid peroxidase, protein carbonyl, and reactive oxygen species) and neurotransmitter-related parameters (dopamine, dopamine transporter acetylcholine, and synuclein alpha levels, acetylcholinesterase activity) were measured comparatively in the study groups. VCO reduced amyloid beta and hyperphosphorylated Tau protein levels in the study groups. In addition, oxidative stress levels decreased, and neurotransmitter parameters improved with VCO. Our study shows that VCO may have potential therapeutic effects in Alzheimer's disease and further experiments are needed to determine its efficacy.

Prabha S, Tamoli S, Raghavamenon AC, Manu KA. Virgin Coconut Oil Alleviates Dextran Sulphate-Induced Inflammatory Bowel Disease and Modulates Inflammation and Immune Response in Mice. JOURNAL OF THE AMERICAN NUTRITION ASSOCIATION 2024; 43:261-271. [PMID: 37905950 DOI: 10.1080/27697061.2023.2266742] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/23/2023] [Accepted: 09/29/2023] [Indexed: 11/02/2023]
Abstract
OBJECTIVE Virgin coconut oil (VCNO), an unrefined kernel oil from Cocos nucifera L., has considerable medicinal and nutritive value. Experimental evidence suggests its antioxidant, anti-inflammatory, chemoprotective, analgesic, and hypolipidemic effects. Presently, the effect of VCNO on ameliorating dextran sodium sulfate (DSS)-induced inflammatory bowel disease and cyclophosphamide (CTX)-induced immunosuppression in experimental animals was analyzed. METHOD DSS (4%) was administered to BALB/c mice through drinking water for 12 days to induce inflammatory bowel disease, and VCNO (500, 750, and 1000 mg/kg bwt) was supplemented orally for 12 days. For anti-inflammatory studies, lipopolysaccharide (LPS, 250 µg/animal) was injected into the intraperitoneal cavity of Swiss albino mice followed by 7 days' pretreatment of VCNO (500, 750, and 1000 mg/kg bwt). To understand the mechanism of action, serum from all animals was collected after 6 hours of LPS challenge and levels of proinflammatory cytokines were analyzed using enzyme-inked immunosorbent assay. In addition to this, immunosuppression was induced by CTX (50 mg/kg bwt, po) in Swiss albino mice. RESULTS Oral administration of VCNO effectively reversed the pathologies associated with inflammatory bowel disease induced by DSS, including loss of body weight, increased disease activity index, shortening of colon length, diarrhea, and rectal bleeding. Histopathological examination showed that VCNO restored the damage in colon tissue induced by DSS. Similar trends were noticed in levels of myeloperoxidase and mRNA expression of proinflammatory cytokines in colon tissue. In addition to this, supplementation of VCNO markedly reduced the hike in the level of serum proinflammatory cytokines in LPS-challenged mice. Further, administration of VCNO effectively increased spleen and thymus indexes and stimulated the production of interferon-γ in serum. CONCLUSIONS Overall, this study revealed that VCNO alleviates inflammatory bowel disease and inflammation; concurrently, it can revert immunosuppression.

Abstract
Virgin coconut oil (VCO) is claimed to have various health benefits, but favorable effects of its major component (∼50%), lauric acid, are controversial. Therefore, we aimed to reduce lauric acid content (∼30%) in VCO and evaluate its effect compared to VCO and medium-chain triglycerides (MCT), on food intake, bodyweight (BW), lipid profiles, and hepatic histology. Female C57BL/6 mice were treated with different diets for 3 months: control (normal diet), high-fat diet (HF), HF + VCO, HF + MCT, HF + low lauric acid VCO (LLA), and normal diet + LLA (C + LLA). LLA was prepared by enzymatic interesterification of VCO with methyl octanoate (methyl caprylate) and methyl decanoate (methyl caprate). Plasma and liver lipids, including total cholesterol (TC), high-density lipoprotein (HDL), and triglyceride, were measured by colorimetric assay, and hepatic fat accumulation was examined by oil-red-O staining. HF mice exhibited high plasma and liver TC and low-density lipoprotein (LDL). VCO or MCT treatment lowered liver TC and LDL, whereas LLA increased plasma HDL and markedly improved TC:HDL ratio. The HF-induced hepatic fat accumulation was attenuated by all treatments, of which VCO was the most effective. Control mice administered with LLA demonstrated lower liver TC and LDL, but higher plasma TC and HDL compared to controls. Lowest BW gain and food intake were found in mice treated with LLA. In conclusion, VCO, MCT, and LLA ameliorated hepatic histopathology caused by HF. VCO and MCT improved liver lipid profiles, whereas LLA has more beneficial effect on plasma lipids via a better TC:HDL ratio and showed promise for BW control.

Abstract
The aim of this study is to evaluate the beneficial effects of coconut essential oil on growth performance, carcass criteria, antioxidant status, and immune response of broiler chicks. A total of 192 un-sexed 7-days broiler chicks were divided into six treatment sets with four copies of 8 chicks per set. The groups were as follows: (1) basal diet (without additive), (2) basal diet plus 0.5 ml coconut essential oil/kg, (3) basal diet plus 1 ml coconut essential oil/kg, (4) basal diet plus 1.5 ml coconut essential oil/kg, (5) basal diet plus 2 ml coconut essential oil/kg and (6) basal diet plus 2.5 ml coconut essential oil/kg. The results showed that the most prevalent compound in coconut oil is 6-Octadecenoic acid (oleic acid) representing 46.44% followed 2(3H)-Furanone, dihydro-5-pentyl- (CAS) (11.36%), Hexadecanoic acid (CAS) (4.71%), and vanillin (2.53%). Dietary 1 and 1.5 ml of coconut oil improved significantly the body weight and gain of broiler chickens. Dietary supplementation of 1 ml of coconut oil improved significantly liver function compared to control and other treatment groups. The supplementation with 1 ml coconut oil significantly reduced TG and VLDL compared to control and other treatment groups, while no significant differences in TC, HDL, and LDL due to dietary coconut oil. The present findings showed that dietary coconut oil with 1 and 1.5 ml/kg feed improved significantly antioxidants status through increased antioxidant enzymes like SOD and GSH while decreasing significantly MDA levels compared to control and other treatment groups. Therefore, it was concluded that the diets of broiler chickens could be fortified with coconut oil with 1 or 1.5 ml to improve the growth, feed utilization, and antioxidant status of broiler chickens.

Virgin Coconut Oil in Paste Form as Treatment for Dyspareunia and Vaginal Dryness in Patients With and Without Rheumatic Autoimmune Diseases: An Efficacy and Safety Assessment Pilot Study. Cureus 2023; 15:e40501. [PMID: 37461787 PMCID: PMC10350307 DOI: 10.7759/cureus.40501] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 06/15/2023] [Indexed: 07/20/2023] Open
Abstract
Introduction The use of virgin coconut oil (VCO) as an over-the-counter (OTC) treatment for vaginal dryness and dyspareunia (VDD) in the general population has increased worldwide despite the absence of evidence-based studies supporting its efficacy. The principal objective of our pilot study was to scientifically validate the significant benefits and safety of using intra- and peri-vaginal application of VCO in paste form (VCOPF) for the treatment of VDD in patients with and without rheumatic autoimmune diseases (RAD). Additionally, multiple psychosocial, sexuality, and disease activity variables were also assessed. Methods A survey study of patients with chronic VDD, with and without RAD, treated with a single proprietary brand of VCOPF via the 'CocoRelief' protocol continuously for at least six months in an outpatient rheumatology practice setting. We evaluated the comparison of group characteristics, treatment outcomes, and satisfaction questions by Fisher's exact test or chi-square test for independence for categorical variables and two-sample t-tests for continuous variables. Results Of the 53 respondents, 31 (58%) had an RAD and 22 (42%) did not. Rheumatoid arthritis and primary Sjogren's syndrome comprised 75% of the RAD group. The non-RAD cohort had both a higher baseline mean of intercourse pain (on a scale of 0-5) before VCOPF use (4.4 (SD 1.1) vs 3.9 (SD 1.0) (p = 0.094)) and a higher mean intercourse pain after VCOPF (2.0 (SD 1.3) vs 1.3 (SD 1.1) (p = 0.039)). VDD decreased by 55% in the non-RAD and 66% in the RAD population. Although not statistically significant (p = 0.195), VCOPF was at worst comparable to estrogen-containing therapies (ECT). No adverse events (AE) were documented. Conclusion A high percentage of women with VDD, with and without RAD, needlessly continue to experience quality-of-life-altering physical and psychosocial morbidity due to the underutilization and lack of awareness of VCO-containing therapy. The small sample size, non-blinded, non-randomized, pilot platform, and the use of a non-validated assessment tool represent the principal limiting factors. This study revealed that VCOPF, when used in paste form via the CocoRelief protocol, provided statistically significant long-term VDD-related efficacy not inferior to ECT without AE in patients with and without RAD. VCOPF is, therefore, likely to be a useful, cost-effective alternative in a substantial percentage of patients with and without RAD, particularly in women hesitant to utilize ECT due to cost and/or fear of adverse effects.

Abstract
Osteoarthritis (OA) is a common joint disease and has been studied extensively in recent years as no promising therapy available so far for its treatment and remains a great challenge for health care specialists. Although the identification of some major mechanisms that contribute to this disease suggests a plethora of bioactive agents in tackling the associated complications yet OA's pathophysiology is still poorly understood owing to complex mechanistic changes observed. Experimental research is now exploring a wide range of therapeutically effective agents in an effort to find a way to repair OA-related joint degeneration and halt it from getting worse. Data was acquired and reviewed from most relevant and recent studies. This review summarizes the studies that are currently available and focuses on how various unconventional functional oils affect osteoarthritis and the affected joint tissues. An analysis of the recent scientific literature allowed us to highlight the potential anti-arthritic properties of edible oils and their main constituents, which seems to suggest an interesting new potential therapeutic application. Due to eccentric nature of OA, it is necessary to concentrate initially on the management of symptoms. The evidence supporting functional oils chondroprotective potential is still accumulating, underpinning a global need for more sustainable natural sources of treatment. More clinical research that focuses on the consequences of long-term treatment, possible negative effects, and epigenetic implications is necessary to get optimistic results. However, different animal or clinical studies suggest that linolenic and linoleic fatty acids decreased chondrocyte oxidative stress, cartilage breakdown, and expression of inflammatory markers. Distinct fatty acids along with minor components of oils also reduced the generation of prostaglandins and decreased oxidative stress. Furthermore, the potential roles of the main components of edible oils and possible negative results (if any) are also reported. While no severe side effects have been reported for any edible oils. Overall, these studies identify and support the use of functional oils as an adjuvant therapy for the management of OA and as a means of symptomatic alleviation for OA patients. However, to prove the effectiveness or to draw precise conclusions, high-quality clinical trials are required.

Abstract
BACKGROUND Safer and effective alternatives to manage nicotine dependence are still required. Preliminary studies have shown the potential of virgin coconut oil (VCO) to be used in dependence treatment. OBJECTIVE to assess the VCO effect administered for 14 days on nicotine dependence and quality of life. METHODS Forty smoking subjects participated in an open-label, single-center, pre/post-intervention study, and were required to take 15 ml VCO twice daily for 14 days. They were evaluated with the Fagerstrom Test for Nicotine Dependence (FTND) for nicotine dependence intensity and EuroQol-visual analogue scales (EQ VAS) for quality of life. RESULTS The VCO regimen improved FTND (0.53 points decrease, p<0.05) and EQ-VAS (5.85 points increase p<0.01) scores. Adverse events were all mild. CONCLUSION Results of the present study suggest that VCO has the potential to be a safe and effective adjunct therapy for the management of nicotine dependence.

Abstract
Background Virgin coconut oil is mostly made up of saturated fatty acids in which approximately 72% are medium chain triglycerides. Medium chain triglycerides can be digested into medium chain fatty acids and medium chain monoglycerides which are bioactive components. Therefore, it is very important to study the in-silico ability of some Virgin coconut oil derivatives, namely, medium chain fatty acids and medium chain monoglycerides to inhibit Cyclooxygenase 2 (COX-2) protein for prevention of excessive inflammatory response. Results Pharmacophore study displayed monolaurin with two hydrogen bond donor, three hydrogen bond acceptor and five hydrophobic interactions, while lauric acid presented two hydrogen bond acceptor, five hydrophobic interactions and a negative ion interaction. Molecular docking underlined the ability of monolaurin in the inhibition of COX-2 protein which causes inflammatory action with a decent result of energy binding affinity of - 7.58 kcal/mol and 15 interactions out of which 3 are strong hydrogen bond with TYR385 (3.00 Å), PHE529 (2.77 Å), and GLY533 (3.10 Å) residues of the protein. Monolaurin was employed as hydrogen bond acceptor to the side of residue TYR385 of COX-2 protein with an occupancy of 67.03% and was observed to be long-living during the entire 1000 frames of the molecular dynamic simulation. The analysis of RMSD score of the Monolaurin-COX-2 complex backbone was calculated to be low (1.137 ± 0.153 Å) and was in a stable range of 0.480 to 1.520 Å. Redocking of this complex still maintained a strong hydrogen bond (2.87 Å) with the main residue TYR385. AMDET results where promising for medium chain fatty acids and medium chain monoglycerides with good physicochemical drug scores. Conclusions This can be concluded from the results obtained that the monolaurin has strong interactions with COX-2 protein to disrupt its function due to significant hydrogen bonds and hydrophobic interactions with amino acid residues present in the target protein's active site. These results displayed a very significant anti-inflammatory potential of monolaurin and a new promising drug candidates as anti-inflammatory agent. Graphical Abstract

[PMID: 36140928 PMCID: PMC9498055 DOI: 10.3390/foods11182800] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2022] [Revised: 08/31/2022] [Accepted: 09/07/2022] [Indexed: 11/23/2022] Open
Abstract
Background: Obesity leads to chronic low-grade inflammation, promoting detrimental effects on bone. The consumption of virgin coconut oil (VCO) is associated with benefits related to meta-inflammation. We evaluated the effect of VCO supplementation on osteopenia promoted by diet-induced obesity in mice. Methods: Male BALB/c mice were fed a control (C) or highly refined carbohydrate-containing (HC) diet for eight weeks. After that, the HC diet group was supplemented with three doses of VCO for four weeks. Results: The HC diet increased the adiposity and leptin levels associated with augmented systemic inflammatory cells improved with VCO supplementation. The HC diet reduced the trabecular bone in the tibia, lumbar vertebrae, distal and proximal femur, as well as the bone mineral density of the femur and alveolar bone. The VCO supplementation reverted bone osteopenia by increasing the trabecular bone in different sites and improving femur and alveolar bone microarchitecture. Although the reduced number of osteoblasts in the alveolar bone of the HC diet group was not significantly enhanced by VCO supplementation, the reduced Alp expression in the HC diet group was enhanced in the VCO group. These beneficial effects were associated with lowering the Rankl/Opg ratio. Conclusion: VCO supplementation might be an effective strategy to attenuate bone osteopenic effects induced by obesity.

Linseed, Baru, and Coconut Oils: NMR-Based Metabolomics, Leukocyte Infiltration Potential In Vivo, and Their Oil Characterization. Are There Still Controversies? Nutrients 2022; 14:nu14061161. [PMID: 35334818 PMCID: PMC8950264 DOI: 10.3390/nu14061161] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2022] [Revised: 02/27/2022] [Accepted: 03/02/2022] [Indexed: 02/04/2023] Open
Abstract
Different fatty acid proportions produce potential inflammatory and metabolic changes in organisms. However, the evidence for how each fatty acid mediates the metabolic pathway, and its lipid stability remains controversial. To resolve this controversy, the present study investigated the metabolic effects of cold-pressed linseed (LG), coconut (CG), and baru (BG) oils in comparison to those of soybean oil (SG) in mice, in terms of their oil characterization and stability. The quality analysis showed less oxidative behavior among PUFA-rich oils (SO, BO, and LO, with induction periods lower than 2 h compared to 39.8 h for CG), besides the high contents of tocopherols and carotenoids in SG and LG. In the experimental study, CG presented higher triglyceride (257.93 ± 72.30) and VLDL-cholesterol levels (51.59 ± 14.46, p < 0.05), while LG reduced LDL levels (59.29 ± 7.56, p < 0.05) when compared to SG (183.14 ± 22.06, 36.63 ± 4.41 and 131.63 ± 29.0, respectively). For visceral fats, the adiposity index was lower for BG (7.32 ± 3.13) and CG (9.58 ± 1.02, p < 0.05) in relation to SG (12.53 ± 2.80), and for leukocyte recruitment, CG presented lower polymorphonuclear (PMN) (p < 0.0001) and mononuclear (MN) (p < 0.05) cell infiltration, demonstrating anti-inflammatory potential. In NMR-based metabolomics, although CG presented higher values for the glucose, lactate, and LDL/VLDL ratio, this group also evidenced high levels of choline, a lipotropic metabolite. Our study emphasized the controversies of saturated fatty acids, which impair serum lipids, while alfa-linolenic acid presented cardioprotective effects. However, coconut oil also has a positive immunomodulatory pathway and was found to reduce visceral bodyfat in mice. Therefore, for future applications, we suggest a combination of lauric and al-fa-linolenic acid sources, which are present in coconut and linseed oil, respectively. This combination could be less obesogenic and inflammatory and exert cardioprotective action.

Abstract
Natural adjuvants are novel options to reduce the doses of chemical herbicides. The aim of the current study was to examine the compositions and adjuvant effects of rosin and coconut oil on herbicides using a combination of indoor experiment and field trial. The GC-MS results showed that the main component of rosin was abietic acid (40.02%), and the main components of coconut oil were 2-pentanone, 4-hydroxy-4-methyl- (21.45%) and dodecanoic acid (14.59%). In greenhouse experiment, rosin showed a significant adjuvant effect on nicosulfuron against Digitaria sanguinalis and Amaranthus retroflexus, with the GR50 ratios of 1.47 and 1.69, respectively. The GR50 values of nicosulfuron in the present of coconut oil were 3.99 and 10.13 g a.i./hm2 against D. sanguinalis and A. retroflexus, lower than that of individual application. The adjuvant effect of rosin and coconut oil on mesotrione was also found. In field trial, the fresh weight control efficiency of nicosulfuron (45 g a.i./hm2) and mesotrione (112.5 g a.i./hm2) was significantly improved after the addition of rosin and coconut oil, similar with that of recommended dose. Rosin and coconut oil could reduce the contact angle of nicosulfuron, with the results of 56.68° and 53.90°, respectively, lower than that of individual application. Furthermore, rosin and coconut oil could decrease the surface tension, wetting and penetration time; and increase the spreading diameter and maximum retention. Both rosin and coconut oil have adjuvant effects on herbicides in the lab & field with multiple mechanisms. Thus, they have the potential to be developed into natural adjuvants for herbicide formulation to control weeds.

Illam SP, Narayanankutty A, Kandiyil SP, Raghavamenon AC. Variations in natural polyphenols determine the anti-inflammatory potential of virgin coconut oils. J Food Sci 2021; 86:1620-1628. [PMID: 33864246 DOI: 10.1111/1750-3841.15705] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2020] [Revised: 02/18/2021] [Accepted: 03/02/2021] [Indexed: 11/30/2022]
Abstract
Virgin coconut oil (VCO), an edible oil prepared from fresh coconut kernel by natural or mechanical means without undergoing chemical refining, has been in the limelight of research as functional food oil. The phenolic components in VCO have been accredited with these pharmacological benefits. The present study compared the phenolic constituents of freshly prepared fermentation processed (FVCO) and hot-pressed VCO (HVCO) and their anti-inflammatory efficacies. The biochemical analysis documented quantitative variation in the phenolic content, being higher in HVCO than FVCO (40.03 ± 5.8 µg and 25.55 ± 5.8 µg/mL of oil, respectively). In vitro studies observed nitric oxide radical scavenging efficacy (IC50 value of 14.84 ± 0.81 µg/mL) for HVCO polyphenols, which shows higher inhibition efficacy than FVCO (29.41 ± 1.7 µg/mL). In dextran and formalin mediated acute and chronic inflammation in mice, HVCO displayed more protective efficacy (40.5 and 46.4% inhibition) than FVCO (33.3 and 43.8% inhibition), which is similar to the standard diclofenac (55.6 and 59.8% inhibition). The study, thus, concludes that compared to FVCO, HVCO is a more active anti-inflammatory agent. PRACTICAL APPLICATION: Virgin coconut oil, a widely used edible oil in South Asian countries, has been shown to have health benefits possibly exerted by the natural phenolics it contains. However, different modes of preparations of VCO determine the phenolic combinations and efficacy as well. Our study compared two different VCO preparations and suggests that the VCO prepared by the traditional way (HVCO) is pharmacologically potent than that prepared by simple fermentation process (FVCO) in reducing inflammation. The efficacy is attributed to the variations in phenolic profile revealed by LC-MS analysis. Hence, the current study suggests HVCO as a potential food supplement that can reduce the incidence of degenerative diseases.

Abstract
INTRODUCTION Coconut oil has been considered as a therapeutic alternative in several pathologies, but there is limited information regarding its effects on brain functioning. OBJECTIVE This study analyzed whether early virgin coconut oil (VCO) supplementation interferes with electrical activity of the adult rat brain and its lipid peroxidation. Moreover, it investigated whether the putative effect on brain electrophysiology could be affected by overnutrition occurring during lactation, and/or by environmental enrichment (EE). Electrophysiology was measured through cortical spreading depression (CSD), a phenomenon related to brain excitability. METHODS Wistar rats were suckled in litters of either nine or three pups, forming nourished (N) or overnourished (ON) groups, respectively. Between the 7th and 30th days of life, half of the animals in each group received VCO (10 mg kg-1 d-1; by gavage). The other half received an equivalent amount of vehicle (V, 0.009% cremophor). On day 36, animals from both groups were subjected to EE for 4 weeks. At 105 ± 15 days of life, each animal was subjected to CSD recordings and lipid peroxidation analyses. RESULTS Overnutrition during lactation enhanced body and brain weights. VCO decelerated the CSD propagation velocity (control - 3.57 ± 0.23 mm min-1versus VCO - 3.27 ± 0.18 mm min-1; p < 0.001), regardless of whether subjected to overnourishment or EE exposure. Neither VCO nor EE modified the cerebral lipid peroxidation (p > 0.05). CONCLUSION VCO supplementation impaired the spreading of CSD, indicating reduction of brain excitability. VCO effects occurred regardless of the nutritional state during lactation.

Coconut Oil Supplementation Does Not Affect Blood Pressure Variability and Oxidative Stress: A Placebo-Controlled Clinical Study in Stage-1 Hypertensive Patients. Nutrients 2021; 13:nu13030798.

Abstract
Exploring an alternative to improve the clinical management of hypertension, we tested the hypothesis that food supplementation with coconut oil (EVCO), alone or combined with aerobic exercise training, could exert an antihypertensive effect (primary outcome) in patients with stage 1 hypertension. Forty-five hypertensive volunteers of both genders participated in a placebo-controlled clinical trial. The volunteers were submitted to 24-hour ambulatory blood pressure monitoring, analysis of blood pressure variability (BPV), measurement of serum malondialdehyde (MDA) and nutritional assessment. Results indicate that EVCO consumption had no adverse effects. The supplementation did not increase the caloric intake compared with placebo, and the dietary constituents were similar between groups, except for the saturated fats, especially lauric acid. The analysis of blood pressure indicated absence of antihypertensive effect of EVCO alone or combined with physical training. Furthermore, no effects on blood pressure variability and oxidative stress were observed in the supplemented hypertensive patients. Thus, despite the results observed in pre-clinical studies, the current clinical study did not provide evidence to support the use of coconut oil as an adjuvant in the management of hypertension in humans.

Abstract
Osteoclasts, bone-resorbing somatic cells, are directly responsible for bone destruction during rheumatoid arthritis. Complete Freund adjuvant (CFA) is a widely used animal model using rodents for studying rheumatoid arthritis (RA), which effectively manifests serious cartilage destruction and progressive bone erosion, affecting synovial joints and serious joint dysfunction. It was considered that joint injury in RA is induced through systemic inflammation pathway. Umbelliferone (UF), a coumarin derivative of Agele marmilosa, possesses anti-inflammatory activity. In the current study, we scrutinize the effect of umbelliferone on CFA-induced arthritis model and explore the possible mechanism on bone destruction. Intradermal administration of CFA (0.05 mL) was to induce RA manifestations in the experimental rats and the same oral administration of UF was received. The anti-arthritic activity of UF was determined by its inhibitory activity on various biochemical markers, viz., pro-inflammatory, inflammatory, antioxidant enzymes, and hematological parameters elevated during RA condition. We also estimated the mRNA expression of osteoclast parameters. Obtained result disclosed significant reduction in the paw edema and increment of the body weight after UF administration. UF reduce the inflammatory mediatory such as COX-2, PGE2, NF-kB, and VEGF; pro-inflammatory cytokines include TNF-α, IL-1β, IL-6, IL-10, and IL-17 significantly. Moreover, UF treatment significantly reduced the osteoclast number via modulating the RANKL/RANK/OPG ratio. Furthermore, administration of umbelliferone significantly (P < 0.001) suppressed the NF-κB and VEGF. Collectively, our results indicated the novel role of umbelliferone in osteoclastogenesis and proved that umbelliferone is a modern therapeutic tool as a natural agent for treating arthritis and other autoimmune disorders with bone degradation.

Abstract
Neuroinflammation is associated with neuronal cell death and could lead to chronic neurodegeneration. This study investigated the neuroprotective potential of virgin coconut oil (VCO) against lipopolysaccharide (LPS)-induced cytotoxicity of neuroblastoma SK-N-SH cells. The findings were validated using Wistar rats, which were fed with 1-10 g/kg VCO for 31 days, exposed to LPS (0.25 mg/kg) and subjected to the Morris Water Maze Test. Brain homogenate was subjected to biochemical analyses and gene expression studies. α-Tocopherol (α-T; 150 mg/kg) served as the positive control. VCO (100 µg/mL) significantly (p < 0.01) improved SK-N-SH viability (+57%) and inhibited reactive oxygen species (-31%) in the presence of LPS. VCO (especially 10 g/kg) also significantly (p < 0.05) enhanced spatial memory of LPS-challenged rats. Brain homogenate of VCO-fed rats was presented with increased acetylcholine (+33%) and reduced acetylcholinesterase (-43%). The upregulated antioxidants may have reduced neuroinflammation [malondialdehyde (-51%), nitric oxide (-49%), Cox-2 (-64%) and iNos (-63%)] through upregulation of IL-10 (+30%) and downregulation of IL-1β (-65%) and Interferon-γ (-25%). There was also reduced expression of Bace-1 (-77%). VCO-induced neuroprotection, which was comparable to α-T, could be mediated, in part, through inflammatory, cholinergic and amyloidogenic pathways.

Abstract
Obesity reaches an epidemic level worldwide, and this condition is associated with chronic low-grade inflammation and secondary comorbidities, largely driven by global changes in lifestyle and diet. Various dietary approaches are proposed for the obesity treatment and its associated metabolic disorders. Good taste, antioxidant functions, and vitamins have been attributed to virgin coconut oil (VCO). However, VCO contains a large amount of saturated fatty acids, and the consumption of this fat is associated with a number of secondary diseases. We evaluate the effects of VCO supplementation on biochemical, inflammatory, and oxidative stress parameters in rats fed with high-fat diet (HFD). After feeding with HFD for 12 weeks, the animals were supplemented with VCO for 30 days. HFD+VCO group increased in diet intake, weight gain, low-density lipoprotein cholesterol level, and aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels. These findings were accompanied by increased in hepatic lipid profile and fat deposition in the liver. Adipocyte hypertrophy was observed in the HFD+VCO group, which was associated with elevated expression of tumor necrosis factor alpha (TNF-α) in adipose tissue. These results revealed that VCO associated with HFD induced important metabolic alterations, adipose inflammation, and hepatic lipid accumulation in rats.

Abstract
Asthma is a chronic inflammatory disease of the airways characterized by immune cell infiltrates, bronchial hyperresponsiveness, and declining lung function. Thus, the possible effects of virgin coconut oil on a chronic allergic lung inflammation model were evaluated. Morphology of lung and airway tissue exhibited peribronchial inflammatory infiltrate, epithelial hyperplasia, and smooth muscle thickening in guinea pigs submitted to ovalbumin sensitization, which were prevented by virgin coconut oil supplementation. Additionally, in animals with lung inflammation, trachea contracted in response to ovalbumin administration, showed a greater contractile response to carbachol (CCh) and histamine, and these responses were prevented by the virgin coconut oil supplementation. Apocynin, a NADPH oxidase inhibitor, did not reduce the potency of CCh, whereas tempol, a superoxide dismutase mimetic, reduced potency only in nonsensitized animals. Catalase reduced the CCh potency in nonsensitized animals and animals sensitized and treated with coconut oil, indicating the participation of superoxide anion and hydrogen peroxide in the hypercontractility, which was prevented by virgin coconut oil. In the presence of L-NAME, a nitric oxide synthase (NOS) inhibitor, the CCh curve remained unchanged in nonsensitized animals but had increased efficacy and potency in sensitized animals, indicating an inhibition of endothelial NOS but ineffective in inhibiting inducible NOS. In animals sensitized and treated with coconut oil, the CCh curve was not altered, indicating a reduction in the release of NO by inducible NOS. These data were confirmed by peribronchiolar expression analysis of iNOS. The antioxidant capacity was reduced in the lungs of animals with chronic allergic lung inflammation, which was reversed by the coconut oil, and confirmed by analysis of peribronchiolar 8-iso-PGF2α content. Therefore, the virgin coconut oil supplementation reverses peribronchial inflammatory infiltrate, epithelial hyperplasia, smooth muscle thickening, and hypercontractility through oxidative stress and its interactions with the NO pathway.

Abstract
Background Virgin coconut oil (VCO), a cold processed form of coconut oil, is traditionally consumed in Asian countries owing to its nutritional and medicinal properties. The aim of this study was to investigate whether the health benefits of VCO involve alterations in immune responses that are regulated by intracellular signaling molecules in the spleens of rats. Methods Young male Wistar rats were fed with three doses of VCO in diet for 30 days. At the end of the treatment period, spleens were isolated and in vitro effects on immune responses (Concanavalin A [Con A]-induced lymphoproliferation and cytokine production), and direct effects of VCO treatment on intracellular signaling molecules and antioxidant status were examined. Serum was collected to measure glucose, lipid levels, and leptin. Results VCO supplementation in diet enhanced Con A-induced splenocyte proliferation and Th1 cytokine production while it suppressed the proinflammatory cytokine production. VCO increased the expression of mechanistic target of rapamycin (p-mTOR), sirtuin1 (SIRT1), liver kinase B1 (p-LKB1) p-ERK, and p-CREB in spleen. Similarly, VCO increased the activities of antioxidant enzymes while it suppressed lipid peroxidation in the spleen. VCO diet had hypolipidemic effects on the rats: an increase in high density lipoprotein cholesterol (HDL-C) levels while lowering triacylglycerol (TAG) levels. Conclusion The health benefits of VCO may be mediated through enhanced Th1 immunity through the upregulation of survival signaling pathways and inhibition of free radical generation in the spleen besides its capacity to induce hypolipidemia.

Abstract
Cadmium (Cd) is a ubiquitous non-essential environmental and industrial toxicant that affects various organs in humans and experimental animals. Robust evidence confirms the contribution of oxidative stress to the pathogenesis of Cd-induced hepatic damage. Potent polyphenols found in virgin coconut oil (VCO) are free radical scavengers that may be beneficial against Cd hepatotoxicity. Thus, we aimed to evaluate the possible protective effect of polyphenols isolated from VCO on Cd-induced hepatotoxicity and oxidative stress in rats. Rats were pretreated with polyphenols isolated from VCO (10, 20, and 50 mg/kg, orally) 2 weeks prior to concurrent Cd administration (5 mg/kg, orally) for 5 weeks. Subsequently, liver damage, hepatic oxidative stress, and histopathological alterations were evaluated. In vitro antioxidant assays (DPPH and FRAP) were carried out on VCO polyphenols. Cadmium induced liver damage demonstrated by significant alterations in serum markers of liver damage, as well as pronounced decrease in albumin and total protein compared to control. Further, Cd remarkably depressed hepatic activity of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), and glutathione (GSH) content. Hepatic lipid peroxidation was markedly increased as highlighted by malondialdehyde (MDA) content. Sub-chronic administration of VCO polyphenols to Cd-treated rats produced a significant hepatoprotective effect and restored hepatic oxidative stress markers comparable to control. The prominent improvement in histopathology of rat liver confirmed the biochemical findings. The findings suggest potential beneficial effect of VCO polyphenols on Cd-induced hepatotoxicity and oxidative stress in rats; the mechanism underlying this action is associated with improvement in antioxidant defense system.

Abstract
BACKGROUND Research studies that holistically investigated the effect of administration of Virgin Coconut Oil (VCO) on diabetic humans or animals are limited in literature. OBJECTIVE To investigate the effect of administration of VCO on lipid profile, markers of hepatic and renal dysfunction, and hepatic and renal antioxidant activities of alloxan induced diabetic rats. METHODS Twenty-four male albino rats were used, and they were divided into four groups of six rats each. Group 1 (Normal Control, NC) received distilled water (1 mL/kg); Group 2 (VCO Control) received VCO (5 mL/kg); Group 3 (Diabetic Control, DC) received distilled water (1 mL/kg); Group 4 (Test Group, TG) received 5 ml/kg of VCO. RESULTS There were no significant differences in blood glucose, body weights, relative liver weights, relative kidney weights, hepatic and renal Superoxide Dismutase (SOD) activities, Malondialdehyde (MDA), albumin, aspartate Amino Transaminase (AST), alanine Amino Transaminase (ALT), Alkaline Phosphatase (ALP), urea, creatinine, uric acid, total cholesterol, triacylglycerol, Very Low Density Lipoprotein cholesterol (VLDL) and Low Density Lipoprotein cholesterol (LDL) concentrations; significant increases in renal Glutathione (GSH), hepatic catalase, Glutathione Peroxidase (GPx) and GSH but significant reduction in renal GPx and catalase activities of VCO control group compared with NC group. There were significant increases in blood glucose, relative liver and kidney weights, hepatic GPx, hepatic and renal MDA concentration, ALP, AST, ALT, urea, creatinine, uric acid, triacylglycerol, total cholesterol, LDL and VLDL concentrations; and significant decreases in body weight, hepatic SOD and GSH activities and albumin concentration but no significant difference in hepatic catalase activity of DC group compared with NC group. Administration of VCO to diabetic rats positively modulated these parameters compared with the diabetic control. CONCLUSION The study showed the potentials of VCO in the management of hyperlipidemia, renal and hepatic dysfunctions imposed by hyperglycemia and by oxidative stress in diabetic rats.

Abstract
The present study assessed the effect of dietary supplementation with coconut oil (CNO), watercress oil (WCO), and their mixture as promoters of growth, antioxidant status, immunity, and intestinal microbiota in growing rabbits. A total of 120 rabbits were distributed into six groups (20 rabbits/group) receiving a basal diet without supplementation (G1) or diet supplemented with 2 g CNO (G2), 2 g WCO (G3), 0.5 g CNO plus 1.5 g WCO (G4), 1 g CNO plus 1 g WCO (G5), or 1.5 g CNO plus 0.5 g WCO/kg (G6). Live body weight and feed conversion ratio were significantly higher in the G4 and G5 groups than in the other groups. Superoxide dismutase activity and reduced glutathione concentration were significantly improved in the CNO or WCO diets. Supplemental CNO plus WCO at all tested levels produced the best lysozyme and complement 3 activities. Cecal lactobacilli, coliform, Enterobacteriaceae, and Clostridium spp. populations were lower in the group who received the 1 g CNO + 1 g WCO/kg diet than that in the control group. Dietary supplementation of 1 g CNO + 1 g WCO or 0.5 g CNO + 1.5 g WCO/kg had the potential to improve growth, feed utilization, antioxidant status, and immunity, and reduce cecal pathogenic bacteria in rabbits.

Abstract
The global rise in obesity rates is alarming since this condition is associated with chronic low-grade inflammation and secondary comorbidities as glucose intolerance, cardiovascular disease and liver damage. Therefore, a lot of dietary approaches are proposed to prevent and to treat obesity and its associated disorders. Virgin coconut oil (VCO) is well known as a functional food due to its significant amounts of medium-chain triglycerides. This study aimed to evaluate the effect of VCO on adiposity, metabolic and inflammatory dysfunctions induced by a high-refined carbohydrate-containing (HC) diet in mice. Male BALB/c mice were divided into two groups and fed with control (C) or HC diet to induce obesity for eight weeks. At the 9th week mice fed with HC diet were randomly regrouped into four groups, and were kept this way until the 12th week, as following: (i) HC diet alone or HC diet supplemented with three different VCO doses (ii) 1000 mg/kg, (iii) 3000 mg/kg and (iv) 9000 mg/kg. Regardless of the concentration used, VCO supplementation promoted lower adiposity and also improvement in glucose tolerance, lower serum glucose and lipid levels and decreased hepatic steatosis. Moreover, VCO intake induced a lower inflammatory response due to decreased number of leukocytes and TNF-α and IL-6 concentrations in adipose tissue, as well as reduced counts of total leukocytes, mononuclear and polymorphonuclear circulating cells. Our data showed that VCO can be considered as an interesting potential dietary approach to attenuate obesity and its metabolic and inflammatory alterations.

Abstract
Background Methotrexate (MTX) is a commonly used antineoplastic and anti-rheumatoid agent whose efficacy is limited by marked organ toxicities associated with oxidative stress. The study investigated beneficial effect of virgin coconut oil (VCO) supplementation on MTX-induced oxidative stress and inflammation in rats. Methods Rats were divided into 4 groups (n = 6): Control, MTX (20 mg/kg bw), VCO (5%) + MTX and VCO (15%) + MTX. The pre-treatment with VCO for 14 days was followed by single intraperitoneal injection of MTX and the rats were sacrificed after 3 days. Serum activities of superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx), and levels of reduced glutathione (GSH) and malondialdehyde (MDA) were determined. Interleukin-6 (IL-6), C-reactive protein (CRP) and nitric oxide (NO) levels were also evaluated. Results MTX induced a distinct diminution in serum activities of oxidative stress markers (SOD, CAT, GPx and GSH), while lipid peroxidation considerably increased demonstrated by MDA level. Similarly, levels of IL-6, CRP and NO increased prominently in MTX control rats. The VCO supplementation markedly enhanced resistance to the MTX-induced biochemical alterations in rats. Conclusion VCO can be a useful adjuvant natural product in MTX chemotherapy by reducing oxidative stress and pro-inflammatory responses.

Abstract
BACKGROUND Hepatosteatosis, a form of nonalcoholic fatty liver disease (NAFLD), is being increasingly recognized as a major health burden worldwide. Insulin resistance, dyslipidemia and imbalances in adipokine/cytokine interplay are reported to be involved in the onset and progression of this disease. Use of dietary nutraceuticals in prevention and treatment of NAFLD is emerging. Virgin coconut oil (VCO), a fermented product of fresh coconut kernel, has been shown to impede the development of hepatosteatosis in rats. This study analyzes the potential of VCO to reverse the already developed hepatosteatosis condition. RESULTS Hyperglycemia, reduced glucose tolerance, dyslipidemia, and hepatic macrovesicles in high-fructose-diet-fed rats (4 weeks) confirmed the development of hepatosteatosis. Natural reversion in these parameters was observed upon shifting to normal diet in untreated control animals. Administration of VCO, however, increased this natural reversion by improving high-density lipoprotein cholesterol level (53.5%) and reducing hepatic and serum triacylglycerols (78.0 and 51.7%). Increased hepatic glutathione level (P < 0.01), antioxidant enzyme activities (P < 0.05) and reduced lipid peroxidation were also noticed in these animals. These observations were in concordance with reduced liver enzyme activities (P < 0.01) and restoration of altered hepatic architecture. CONCLUSION The study indicates that VCO can be used as a nutraceutical against hepatosteatosis. © 2017 Society of Chemical Industry.

Role of antioxidant defence, renal toxicity markers and inflammatory cascade in disease progression of acute pyelonephritis in experimental rat model. Microb Pathog 2017; 109:189-194. [PMID: 28578087 DOI: 10.1016/j.micpath.2017.05.047] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2016] [Revised: 05/19/2017] [Accepted: 05/30/2017] [Indexed: 11/22/2022]
Abstract
Urinary tract infections are the most common bacterial infections affecting millions of people each year worldwide. The animal model provides an excellent and suitable system for studying cystitis and pyelonephritis caused by Escherichia coli and other uropathogens. Using this established model, we evaluate the role of antioxidant defence system, renal injury markers, and blood parameters in the diseases progression during Escherichia coli infection on 0th day, 12h and 7th day. The antioxidant enzymes like SOD, CAT, GSH, GPx, GR levels were evaluated. The blood parameters like AST, ALT, ALP, Total protein, BUN, creatinine level were estimated in infection model. The relative organ weights, anti microbial status of kidney, CRP, WBC count were done for the evaluation of inflammatory response associated with the infection. The oxidative stress marker like MDA was also evaluated. Histopathological analysis of renal tissue provides direct vision to tissue damage. The antioxidant status of renal tissue was decreased during the 7th day of infection. Likewise, renal toxicity markers were significantly increased during bacterial infection. The inflammatory markers like CRP, WBC count and oxidative stress marker like MDA were significantly increased by the infection on 7th day. The histopathology of renal tissue also reveals the inflammation and tissue damage associated with acute pyelonephritis.

Abstract
BACKGROUNDS Inula helenium L. is an herb with anti-inflammatory properties. Sesquiterpene lactones (SLs), mainly alantolactone (AL) and isoalantolactone (IAL), are considered as its active ingredients. However, the anti-inflammatory effects of SL-containing extracts of I. helenium have not been explored. Here we prepared total SLs from I. helenium (TSL-IHL), analyzed its chemical constituents, and performed cellular and animal studies to evaluate its anti-inflammatory activities. MATERIALS AND METHODS The chemical profile of TSL-IHL was analyzed by HPLC-UV. Its in vitro effects on the activation of signaling pathways and expression of inflammatory genes were examined by western blotting and quantitative real-time PCR, respectively, and compared with those of AL and IAL. Its in vivo anti-inflammatory effects were evaluated in adjuvant- and collagen-induced arthritis rat models. RESULTS Chemical analysis showed that AL and IAL represent major constituents of TSL-IHL. TSL-IHL, as well as AL and IAL, could inhibit TNF-α-induced activation of NF-κB and MAPK pathways in b. End3 cells, suppress the expressions of MMP-3, MCP-1, and IL-1 in TNF-α-stimulated synovial fibroblasts, and IL-1, IL-6, and iNOS in LPS-activated RAW 264.7 cells in a dose-dependent manner in the range of 0.6-2.4μg/mL. Oral administration of TSL-IHL at 12.5-50mg/kg could dose-dependently alleviate the arthritic severity and paw swelling in either developing or developed phases of arthritis of rats induced by adjuvant or collagen CONCLUSIONS: These results indicated potentials of TSL-IHL in prevention and therapy of rheumatoid arthritis.

Abstract
CONTEXT Pachygone ovata (Poir.) Miers ex Hook. F. et Thoms (Menispermaceae) is a rich source of bioactive bisbenzylisoquinoline and aporphine alkaloids. OBJECTIVE This study investigates the in vitro and in vivo anti-inflammatory and antinociceptive potential of Pachygone ovata leaves. MATERIALS AND METHODS Lipoxygenase (LOX) assay for anti-inflammatory activity was conducted using MeOH, EA, H and Aq extracts; followed by alkaloid isolation. The anti-inflammatory potential was determined using carrageenan-induced paw oedema and formalin tests for evaluation of Pachygone ovata analgesic effect. Different doses (100, 300 and 400 μg/kg) were administered orally to Wistar rats for a period of one week, once daily. RESULTS MeOH and EA extract efficiently inhibited LOX (IC50 1.43 and 2.15 μg/mL, respectively). MeOH extract had better inhibiting capacity (57%) than indomethacin (51%) in carrageenan induced rats. MeOH extract (300 μg/kg) significantly reduced the increased levels of nitric oxide (8 ± 0.57 M), total leukocyte count (4.5 ± 0.05 cells 103/cells) and C-reactive protein (55 ± 0.45 mg/mL). There was a decrease in various serum biochemical markers (ALT, AST). Histopathological studies revealed reduction in oedema and decreased cellular infiltration on supplementation with MeOH extract. Furthermore, MeOH extract (300 μg/kg) and alkaloid fraction (400 μg/kg) effected both phases (neurogenic and inflammatory) of formalin injected models. DISCUSSION AND CONCLUSION Inflammatory mediators play a key role in inflammation; therefore, keeping it in control is of utmost importance. The usefulness of Pachygone ovata leaves on pain and inflammation has been described, probably due to its effect on inflammatory mediators and high alkaloid content.

Abstract
Virgin coconut oil, rich in antioxidants, was shown to attenuate hypertension. This study aimed to investigate the effects of virgin coconut oil on blood pressure and related parameters in kidneys in rats fed with 5-times-heated palm oil (5HPO). Thirty-two male Sprague–Dawley rats were divided into 4 groups. Two groups were fed 5HPO (15%) diet and the second group was also given virgin coconut oil (1.42 mL/kg, oral) daily for 16 weeks. The other 2 groups were given basal diet without (control) and with virgin coconut oil. Systolic blood pressure was measured pre- and post-treatment. After 16 weeks, the rats were sacrificed and kidneys were harvested. Dietary 5HPO increased blood pressure, renal thiobarbituric acid reactive substance (TBARS), and nitric oxide contents, but decreased heme oxygenase activity. Virgin coconut oil prevented increase in 5HPO-induced blood pressure and renal nitric oxide content as well as the decrease in renal heme oxygenase activity. The virgin coconut oil also reduced the elevation of renal TBARS induced by the heated oil. However, neither dietary 5HPO nor virgin coconut oil affected renal histomorphometry. In conclusion, virgin coconut oil has a potential to reduce the development of hypertension and renal injury induced by dietary heated oil, possibly via its antioxidant protective effects on the kidneys.
