Abstract

Background: Vitamin D deficiency is frequently correlated with elevated malondialdehyde (MDA) levels and decreased superoxide dismutase (SOD) activity. Several studies have demonstrated that vitamin D3 can reverse intracellular oxidative stress. However, vitamin D is prone to deterioration and instability. Liprotides contain lipids and proteins that can prevent vitamin D from oxidating.Objective: This study aims to investigate the effects of liprotide-encapsulated vitamin D3 on MDA concentrations and SOD activity in calcium and vitamin D-deficient rat models.Methods: The experimental post-test-only control group study used 24 Wistar rats randomly in 4 groups. Groups K(-), K(+), and P were fed a vitamin D and calcium-depleted AIN-93M diet for 14 days. Standard feed AIN-93M was received by normal groups (KN). Groups K- were deficient rats in vitamin D and calcium without intervention. The groups of  K+ and P were given vitamin D3 (180 IU) which was non-encapsulated and liprotide-encapsulated for 28 days.The SOD activity was quantified with Superoxide Dismutase (SOD) Activity Assay Kit, while MDA levels were determined using Thiobarbituric Acid Reactive Substance (TBARS) method. The statistical analysis used One-way ANOVA test with Least Significant Difference follow-up test.Results: The MDA levels and SOD activity in the K+ and P groups had significant differences (p<0.05) against the control group. Liprotides-encapsulated vitamin D3 significantly reduced MDA levels and enhanced SOD activity compared to non-encapsulated in rats with a deficiency in vitamin D and calcium.Conclusion: Liprotide-encapsulated vitamin D3 has the potential to increase SOD activity and decrease MDA levels.

Abstract

Background: Tempeh is a fermented soybean containing isoflavones that shows good benefits again obesity. Co-fermentation of tempeh using  Lactobacillus rhamnosus GG could increase the bioavailability of isoflavones.Objective: This study aimed to determine the effect of co-fermented tempeh using Lactobacillus rhamnosus GG (tLGG) on body weight (B.W.), Lee Index, high sensitivity C Reactive Protein (hs-CRP), and lipid profile of obese rats. Total flavonoid and genistein were also measured.Methods: Male Sprague Dawley rats (n=36, 200-to-215-gram, age eight weeks) were orally administered high fat and high sucrose diet (HFHS diet) for two weeks to induce obesity. After obesity was confirmed by checking Lee Index, rats were divided into six group and administered orally standard diet (normal control), HFHS diet (negative control), HFHS diet and 120 mg/kg B.W./day-orlistat (positive control), HFHS diet and 60 mg/kg B.W./day standard tempeh  with Rhizopus oligosporus (tS), HFHS diet and 60 mg/kg B.W./day tLGG, HFHS diet and 120 mg/kg B.W./day tLGG for four weeks. Body weight, Lee Index, hs-CRP, and lipid profile were analyzed. Total flavonoid and genistein were analyzed.Results: 120 mg/kg B.W./day tLGG group exhibited significantly lower body weight gains, Lee Index, hs-CRP, triglyceride, total cholesterol, LDL, and higher HDL compared to negative control and tS group (p<0,001), however, positive control group exhibited lower body weight gains compared to tLGG group (p<0,001). Nevertheless, tLGG group exhibited lower Lee Index compared to positive control group.   tLGG showed higher flavonoid and genistein level than tS.Conclusion: Administration of 120 mg/kg B.W./day tLGG showed significantly lower Lee Index compared to all groups given HFHS diet, however, positive control group showed lower body weight gains compared to tLGG group. tLGG also improved hs-CRP and lipid profile two times better than negative control group. tLGG increased total flavonoids and genistein level.
