Hypercholesterolemic Diet

The present objective of the investigation is to evaluate the antihypercholesterolemic activity of the aqueous fruit pulp extract (APE) ofCopernicia prunifera(Miller) H. E. Moore (Arecaceae family). Various chemical characterization methods like thin layer chromatography, Fourier transform infrared spectroscopy,1H and13C NMR, and molecular weight by gel permeation chromatography have been employed to characterize the extracted pectin. The present study demonstrated that hypercholesterolemic diet (HD) created hypercholesterolemia, caused significant increases in body weight, total cholesterol, and low-density lipoprotein, and caused decreases in high-density lipoprotein in serum compared with SD group. Two doses (APE 150 and 300 mg/Kg b.w./day) were administered to hyperlipidemic mice for 90 days. APE reversed body weight changes, changed serum lipids to normal values, and significantly inhibited the changes of lipid peroxidation and inflammation in the liver tissues. The renal parameters analyzed (urea and creatinine) altered by diet were reverted to normal values. Our results revealed that aqueous fruit pulp extracts of carnauba reduced hypercholesterolemia showing a potential preventive effect against cardiovascular diseases without side effects cause.

Background and Objective: Yoghurt, especially bio-yoghurt has long been recognized as a product with many health benefits for consumers. Also, honey and olive oil have considerable nutritional and health effects. So, the effect of administration of yoghurt made using ABT culture and fortified with honey (2 and 6%), olive oil (1 and 4%) or honey + olive oil (2+1 and 6+4% respectively) on some biological and hematological properties of rats was investigated.Methods:The body weight gain, serum lipid level, blood glucose level, serum creatinine level, Glutamic Oxaloacetic Transaminase (GOT) activity, Glutamic Pyruvic Transaminase (GPT) activity, leukocytes and lymphocytes counts of rats were evaluated.Results:Blending of bio-yoghurt with rats' diet improved body weight gain. Concentrations of Total plasma Cholesterol (TC), High-Density Lipoprotein cholesterol (HDL), Low-Density Lipoprotein cholesterol (LDL), Very Low-Density Lipoprotein cholesterol (VLDL) and Triglycerides (TG) significantly lowered in plasma of rats fed bio-yoghurt. Levels of TC, LDL, VLDL, and TG also decreased in rat groups feed bio-yoghurt supplemented with honey and olive oil. LDL concentrations were reduced by 10.32, 18.51, 34.17, 22.48, 43.30% in plasma of rats fed classic starter yoghurt, ABT yoghurt, ABT yoghurt contained 6% honey, ABT yoghurt contained 4% olive oil and ABT yoghurt contained 6% honey + 4% olive oil respectively. The blood glucose, serum creatinine, GOT and GPT values of rats decreased while white blood cells and lymphocytes counts increased by feeding bioyoghurt contained honey and olive oil.Conclusion:The findings enhanced the multiple therapeutic effects of bio-yoghurt supplemented with honey and olive oil.

Abstract Background: This research work investigated the antidiabetic, anti-hyperlipidemic, and antioxidative effects of Anacardium occidentale methanolic nut extract in Streptozotocin (STZ)-induced diabetic Wistar rats. Methods: Forty (40) Wistar rats weighing 250±30g were randomly divided into five groups of 8 rats each. Group 1 served as the control; Group 2-5 were induced with diabetes with a single dose of 50mg/kg bw of streptozotocin intraperitoneally. After diabetes induction, Group 2 served as the STZ-only group, Groups 3 and 4 were administered 100mg/kg bw and 200mg/kg bw p.o Anacardium occidentale nut extract, respectively, while Group 5 was administered 2mg/kg bw of glimepiride as a reference drug for a period of 4 weeks. Food and water intake were monitored daily, body weight, and blood glucose levels weekly throughout the experiment. On day 29, the animals were sacrificed, and blood samples were collected through cardiac puncture for biochemical studies. Results: Administration of the nut extract significantly (p<0.05) increased the food intake and body weight of diabetic treated rats, fasting blood glucose level and oral glucose tolerance test (OGTT) decreased significantly (p<0.05) in treated rats. On lipid profile, administration of nut extract significantly decreased (p<0.05) triglyceride, low-density lipoprotein, total cholesterol, and very-low-density lipoprotein concentrations while it significantly increases (p<0.05) the high-density lipoprotein. Anacardium occidentale nut extract caused significantly (p<0.05) increases in SOD, GPx, GSH, and CAT levels with a decrease MDA level in diabetic treated rats. Markers of liver and kidney functions were also improved in diabetic treated rats.Conclusion: Treatment with Anacardium occidentale methanolic nut extract has hypoglycemic, hypolipidemic, and hepato-protective effects in diabetic rats. It also alleviates oxidative stress activity and restoration of markers of kidney function, and may be useful as alternative therapy in the management of diabetes and its related complications.

Maximal Fat Oxidation

Individuals with abdominal obesity and metabolic syndrome (MetS) have augmented risk of all-cause mortality. Lifestyle interventions are effective to treat MetS, however, there are periods during the year in which exercise programs are discontinued and improper dietary habits reappear (e.g., Christmas holidays). We aimed to analyze if exercise-training during Christmas holidays would avoid body-weight gains and cardiometabolic deterioration in MetS individuals, using a randomized control trial. Thirty-eight men with MetS undergoing exercise training were randomly allocated to either continue (TRAIN group, n = 16) or discontinue (HOLID group, n = 22) training, during the three weeks of Christmas. Anthropometrics (body weight, fat, and waist circumference), fasting blood metabolites (glucose, insulin, triglycerides, and cholesterol concentrations) and exercise maximal fat oxidation (FOMAX) and oxygen uptake (VO2PEAK) were determined before and after Christmas. Both groups were similar at baseline in all parameters (p > 0.05). HOLID group increased body weight (91.3 ± 13.0 to 92.0 ± 13.4 kg, p = 0.004), mean arterial pressure (94.0 ± 10.6 to 97.1 ± 8.9 mmHg, p = 0.026), blood insulin (10.2 ± 3.8 to 12.5 ± 5.4 µIU·mL−1, p = 0.003) and HOMA (3.2 ± 1.3 to 4.1 ± 2.3, p = 0.003). In contrast, TRAIN prevented those disarrangements and reduced total (170.6 ± 30.6 to 161.3 ± 31.3 mg·dL−1, p = 0.026) and low-density lipoprotein cholesterol (i.e., LDL-C, 104.8 ± 26.1 to 95.6 ± 21.7 mg·dL−1, p = 0.013). TRAIN also prevented the reductions in exercise FOMAX and VO2PEAK that was observed in the HOLID group (p = 0.002). In conclusion, exercise training during Christmas, prevents body weight gains and the associated cardiovascular (increase in blood pressure and LDL-C) and metabolic (reduced insulin sensitivity) health risks are an optimal non-pharmacological therapy for that period of the year.

The study was aimed to evaluate the effectiveness of feeding dietary microparticles protein added with Lactobacillus sp. on blood parameters and broiler productivity. A total of 192 birds of 21 days old broiler with initial body weight of 481 ± 67 g were divided into 8 treatments and 4 replications (6 birds each) of a completely randomized design (CRD). Dietary treatments were T0: 21% intact protein ration, T1: 18% intact protein ration, T2: 21% microparticle protein ration, T3: 18% microparticle protein ration, T4: T0 + 1.2 mL Lactobacillus sp, T5: T1 + 1.2 mL Lactobacillus sp., T6: T2 + 1.2 mL Lactobacillus sp., and T7: T3 + 1.2 mL Lactobacillus sp. Parameters observed were total lactic acid bacteria and Coliform, pH, blood cholesterol, low density lipoprotein (LDL), high density lipoprotein (HDL), meat cholesterol, meat weight, feed consumption, and body weight gain (BWG). Data were analyzed using analysis of variance and followed by Duncan test (P<0.05). The results showed that T7 treatment significantly (P<0.05) decreased blood cholesterol, LDL, and meat cholesterol, but increased HDL, meat weight, and BWG. Blood cholesterol, LDL, and meat cholesterol were indicated significantly (P<0.05) lowest values due to T7 treatment. In conclusion, feeding 18% microparticle protein with addition of 1.2 mL Lactobacillus sp. can improves blood status and increases broiler productivity.

The lipoproteins isolated from rat plasma by flotation in the density range 1.019-1.063 g/ml were further characterized. Using rate zonal ultracentrifugation, we isolated two lipoproteins in almost equal proportions from this density range. Similar isolations may be accomplished with density gradients in a swinging-bucket rotor. On isopycnic-density-gradient ultracentrifugation one component banded at rho = 1.031 g/ml and the other at rho = 1.054 g/ml. More that 98% of the apoprotein of the lighter component was B protein, and hence this particle is LD (low-density) lipoprotein. Of the apoproteins of the rho = 1.054 g/ml particles, designated lipoprotein HDL1, over 60% was arginine-rich peptide, and the remainder was A-I, A-IV and C peptides. The molecular weight of these lipoproteins determined by agarose column chromatography was 2.36 × 10(6) for LD lipoprotein and 1.30 × 10(6) for lipoprotein HDL1. On electron microscopy the radius of LD lipoprotein was 14.0 nm and that of lipoprotein HDL1 was 10.0 nm, in contrast with molecular radii of 10.4 nm and 8.4 nm respectively determined from the gel-permeation-chromatography data. The lipid and phospholipid composition of both particles was determined. Lipoprotein HDL1 was notable for both the concentration of its esterified cholesterol, which was similar to that of LD lipoprotein, and the low triacylglycerol content, resembling that of HD lipoprotein. The possible origin of lipoprotein HDL1 is discussed.

The Absolute

MAC188 S/S is a monoclonal antibody which can be used in vivo to measure the absolute number of functioning low-density lipoprotein (LDL) receptors in a rabbit. The antibody binds to the extra-cellular domain of the LDL receptor and binding is not blocked by the presence of LDL. When the antibody-receptor complex is internalized, receptor recycling is inhibited for several hours. Thus when saturating doses of MAC188 S/S are administered intravenously, the amount of antibody removed from the blood (minus non-specific removal) is determined solely by the total number of LDL receptors in an animal. In this study MAC188 S/S was used to measure the number of LDL receptors in control rabbits and in animals treated with 17 alpha-ethinyl oestradiol. After treatment (which caused a 47% decrease in plasma cholesterol), receptor-mediated removal of MAC188 S/S from the blood was saturated in both groups following injection of 3.0 mg of antibody per kg body weight. Based on the amount of antibody removed via the LDL receptor at this dose, the total number of accessible LDL receptors was calculated as (2.0 +/- 0.3) x 10(15) receptors per kg body weight in control rabbits and (4.0 +/- 0.4) x 10(15) receptors per kg body weight in oestrogen-treated animals. The number of receptors in various organs was also determined. The monoclonal antibody approach therefore, allows accurate determination of LDL receptor numbers in animals with markedly different concentrations of circulating LDL, conditions in which the use of endogenous ligand would be subject to significant errors.
