Dose Levels

Increased consumption of high-calorie foods leads to obesity usually associated with metabolic disorders including diabetes, hyperglycemia, and dyslipidemia. Ganoderma applanatum is a nonedible mushroom traditionally used in West Cameroon for the treatment of many diseases including hypertension, diabetes, and hepatitis. This study was designed to investigate the antidyslipidemic potential of water-soluble polysaccharides of G. applanatum in MACAPOS-2- (maize, cassava, palm oil, and sugar) induced obese rats. For this purpose, obesity was induced on 6–8-week-old male Wistar rats with a local high-fat diet for four months. G. applanatum polysaccharides (GAPs) obtained by hot water extraction were orally administered to obese rats for two months at different dose levels (50, 100, and 150 mg/kg bodyweight), and its potential was investigated on food consumption, bodyweight gain, serum, and tissue lipids parameters. GAP extract increased the bodyweight gain by raising the food intake of obese rats. Furthermore, the administration of GAP extract at different dose levels significantly decreased the total cholesterol, triglyceride, low-density lipoprotein cholesterol levels, and the atherogenic index from 50 to 150 mg/kg bodyweight. Conversely, GAP extract improved the high-density lipoprotein cholesterol level in obese rats compared with untreated rats after two months’ study period. These results indicated that GAP extract may be considered as a novel bioactive compound against dyslipidemia and its associated complications.

ABSTRACT Objective To investigate the influence of ultra-processed food consumption on anthropometric and atherogenic indices. Methods A cross-sectional study was conducted with 327 adolescents aged 14 to 19 years. Sociodemographic, anthropometric, biochemical, and food consumption data were evaluated. The ratios of atherogenic indices were calculated using the Castelli I (Total Cholesterol/High Density Lipoprotein Cholesterol), Castelli II (Low Density Lipoprotein Cholesterol/High Density Lipoprotein Cholesterol), and estimated Low Density Lipoprotein Cholesterol particle size (Atherogenic Index of Plasma=Triglycerides/High-Density Lipoprotein Cholesterol) indices. Logistic regression was used for the unadjusted and adjusted analysis between ultra-processed foods consumption, anthropometric, and atherogenic indices. The level of significance was 5%. Results Most participants were female (59.3%). Girls had a higher consumption of ultra-processed foods (26.6% vs. 20.5%). Of the total number of adolescents, 16.5% were overweight and 65.7% were from public schools. Adolescents with altered values for the Castelli I and II Index, and for the Atherogenic Index of Plasma had significantly higher weights, Waist Circumference, Waist Circumference/ Height and Body Mass Index/ Age values. The adjusted analysis identified a significant association (Odds ratio=2.29; 95% Confidence interval: 1.23-4.28) between the high consumption of ultra-processed foods and the Castelli II index. Conclusion The associations between atherogenic indices and anthropometric indices and the consumption of ultra-processed foods highlight the negative influence of these foods on adolescents’ cardiovascular health.

Objective.Many studies have highlighted the hypolipidemic action of hydroxychloroquine (HCQ). We investigated the effect of HCQ on the lipid profile of patients with Sjögren syndrome (SS).Methods.The present retrospective observational study included 71 female patients with SS treated with HCQ. The levels of total cholesterol (TC), high-density lipoprotein cholesterol (HDL), low-density lipoprotein cholesterol, triglycerides (TG), and atherogenic index (TC/HDL) were measured at baseline, after 6 months, and 1, 3, and 5 years after initiation of HCQ treatment. Analysis to investigate changes over time was performed in the entire patient group and in the separate subgroups: those receiving (21 patients) and those not receiving (50 patients) hypolipidemic treatment.Results.For the entire group of patients a statistically significant decrease in TC was noted (levels before treatment 220 ± 41 mg/dl, and at 5 yrs 206 ± 32 mg/dl, p = 0.006). A statistically significant difference was observed in the levels of HDL (57 ± 14 mg/dl vs 67 ± 17 mg/dl, p < 0.001) and in atherogenic index (4.0 ± 1.3 vs 3.3 ± 0.9, p < 0.001). Patients not receiving a hypolipidemic agent during the same period demonstrated a decrease in TC (214 ± 40 mg/dl vs 208 ± 34 mg/dl, p = 0.049), an increase in HDL levels (55 ± 15 mg/dl vs 67 ± 18 mg/dl, p < 0.001), and a decrease in atherogenic index (4.0 ± 1.4 vs 3.3 ± 0.9, p < 0.001). In the subgroup of patients receiving hypolipidemic treatment, the respective changes in their lipid profile were not significant in the first years but became significant in the long term.Conclusion.Use of HCQ in patients with SS was related to a statistically significant decrease in TC, an increase in HDL, and improvement in the atherogenic index.

Abstract Background: Galacto-oligosaccharides (GOS) is a commonly used as a prebiotic with a variety of metabolic benefits. Whether GOS plays a protective role in obesity is still unknown. Here we demonstrated that GOS possesses an anti-obesity activity by promoting adipose tissue browning and thermogenesis. Results: Our results showed that GOS effectively slow weight gain of diet-induced obese (DIO) rats without affecting energy intake. GOS significantly suppressed the hypertrophy and hyperplasia of white adipose tissue (WAT), as well as markedly lessened the ratio of fat pad to fat body. Consistently, GOS significantly improved serum total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) levels, which indicated an appropriate weight loss activity of GOS. Interestingly, GOS also significantly increased the expression levels of browning proteins (UCP1, PPARγ, PGC1α and PRMD16) both in the WAT and brown adipose tissue (BAT). We further found that GOS markedly increased the expression levels of LXRα, PPARα, LDLR and CYP7A1 proteins in the liver of obese rats. Conclusions: Taken together, we concluded that GOS inhibits obesity by accelerating the browning of white fat cells and the thermogenesis of brown fat cells, moreover GOS improves host lipid homeostasis by promoting cholesterol catabolism.

Xanthine Derivatives

Statin side effects are not a rare occurrence, in particular dyspeptic disorders, insomnia, headache, skin erythema, rash are often noted. All of this determines scientists to find new effective and low-toxic hypolipidemic agents. Various natural and synthetic xanthine derivatives have been recognized as therapeutically potential compounds and reported to control various diseases. Therefore, the study of new xanthine derivatives and their hypolipidemic effects, which would have a significant therapeutic effect with minimal side effects, is relevant. The aim of the study was to examine the effect of 7-β-hydroxy-γ-aryloxypropylxanthinyl-8-thioalkanic acid derivatives on lipidogram parameters in experimental laboratory rats. Materials and methods. The objects of the study were 7-β-hydroxy-γ-aryloxypropylxanthinyl-8-thioalkanic acid derivatives. The experiments were performed in white laboratory Wistar rats weighing 180–220 g. Experimental modeling of hyperlipidemia – tween model: intraperitoneal administration of tween-80 at a dose of 200 mg/100 g body weight. The test compounds were administered orally, simultaneously with tween, at a dose of 1/10 of LD50 (previously calculated by Prozorovsky express method) for 6 days. The following indicators of lipidogram were determined: total cholesterol (TC), high-density lipoprotein cholesterol (HDL cholesterol), low-density lipoprotein cholesterol (LDL cholesterol), triglycerides (TG) and atherogenic index of plasma: TC – HDL cholesterol / HDL cholesterol. The experiments were carried out with respect to Bioethical rules and norms. Results. The studies have shown data on the hypolipidemic activity of 7-β-hydroxy-γ-aryloxypropylxanthinyl-8-thioalkane acid derivatives. According to the conditional efficiency index Ʃ, which included the overall percentage of the following indicators – total cholesterol, low-density lipoprotein cholesterol and triglycerides, the leading compounds were 2439 (87.47 %), 6047 (82.30 %). The reference drug atorvastatin had a value of 82.98 %. Conclusions. The major compound was 2439 identified among all compared to the control group. The prospect of further research is a more detailed study on the ability of xanthine derivatives to exhibit hypolipidemic effects and to influence oxidative stress in various hyperlipidemic models.

The purpose of this study was to substantiate the possibility of correcting lipid metabolism changes at dark deprivation using linseed oil, melatonin, and their combination. Materials and methods. The experiment involved 130 white outbred male rats with a body weight of 170–220 g. The animals were divided into 5 groups: rats under standard fixed lighting conditions (12 hours light/12 hours dark); rats under modelled dark deprivation with round-the-clock lighting (24 hours light); rats under modelled dark deprivation with round-the-clock lighting (24 hours light) receiving intragastric injections of linseed oil, melatonin or their combination from day 1 of the experiment. Serum concentrations of total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), total phospholipids (TPL) and atherogenic index (AI) were determined. Results. Long-term dark deprivation led to dyslipoproteinemia, which consists in an increase in serum concentrations of TC by a factor of 1.33 (p = 0.0009), TG by a factor of 1.62 (p = 0.013), LDL-C by a factor of 1.2 (p = 0.026) and TPL by a factor of 1.15 (p = 0.0082). The severity of changes in TC, TG, LDL-C, HDL-C and TPL concentrations varied depending on the duration of the experiment. During the use of linseed oil, melatonin or their combination under dark deprivation, the severity of disorders caused by desynchronosis decreased and lipid metabolism in rat serum normalized, especially at the initial stages of the research. Conclusion. Changes in lipid metabolism due to desynchronosis in rats injected with the substances under study were significantly smaller compared with animals that did not receive them. The most pronounced effects of administering these substances were observed in the group of rats treated with linseed oil and melatonin at the same time.

Dioscoreophyllum cumminsii (Stapf) Diels leaves are widely used in the treatment of diabetes, obesity, and cardiovascular related complications in Nigeria. This study investigates the anti-inflammatory and antiobesity effect of aqueous extract of Dioscoreophyllum cumminsii leaves in high-fat diet- (HFD-) induced obese rats. HFD-fed rats were given 100, 200, and 400 mgkg−1 body weight of aqueous extract of Dioscoreophyllum cumminsii leaves for 4 weeks starting from 9th week of HFD treatment. D. cumminsii leaves aqueous extract reversed HFD-mediated decrease in the activities of superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase, and glucose 6-phosphate dehydrogenase. Moreover, HFD-mediated elevation in the levels of conjugated dienes, lipid hydroperoxides, malondialdehyde, protein carbonyl, and DNA fragmentation in rats liver was lowered. HFD-mediated alterations in serum total cholesterol, triacylglycerol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and very low-density lipoprotein cholesterol were significantly reversed by the extract. The treatment of HFD-fed rats reduced the levels of insulin, leptin, protein carbonyl, fragmented DNA, and tumour necrosis factor-α and interleukin- (IL-) 6 and IL- 8 and increased the adiponectin level. This study showed that aqueous extract of Dioscoreophyllum cumminsii leaves has potential antiobesity and anti-inflammatory effects through modulation of obesity-induced inflammation, oxidative stress, and obesity-related disorder in HFD-induced obese rats.

Background.The apolipoprotein (apo) B/apoA-I ratio represents the balance between apoB-rich atherogenic particles and apoA-I-rich antiatherogenic particles, and this ratio is considered to be a marker of cardiovascular risk. Although many studies have demonstrated the importance of the apoB/apoA-I ratio in predicting the presence or absence of cardiovascular disease, less is known about apoB/apoA-I ratio as a marker of plasma atherogenicity.Methods.A total of 157 normolipidemic men aged 20–59 years were included in the study. The plasma levels of total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), apoA-I, apoB, and apoE were determined after a 12 h fasting period.Results. The median of the apoB/apoA-I ratio in the studied normolipidemic subjects was 0.52, with values ranging from 0.19 to 2.60. The percentage of subjects with the apoB/apoA-I ratio exceeding 0.9 (the accepted risk value of cardiovascular disease) was 19.1%. The subjects with apoB/apoA-I>0.9 were characterized by higher TG levels and atherogenic index of plasma (AIP) and lower values of ratio of low-density lipoprotein cholesterol (LDL-C) to apoB (LDL-C/apoB) and apoE levels compared with men with apoB/apoA-I<0.9.Conclusion. Despite normolipidemia, the subjects with the unfavorable apoB/apoA-I ratio had more atherogenic lipid profile.

The present study was intended to evaluate the effects of Paeonia emodi rhizome extracts on serum triglycerides (TGs), total cholesterol (TC), low density lipoprotein cholesterol (LDL-c), high density lipoprotein cholesterol (HDL-c), atherogenic index (AI), superoxide dismutase (SOD), and glutathione peroxidase (GPx). The plant was extensively examined for its in vitro antioxidant activity, and the preliminary phytochemical screening was carried out using standard protocols. Male Wistar rats were induced with hyperlipidemia using high-fat diet and were treated orally with hydroalcoholic and aqueous extracts at the dose of 200 mg/kg bw for 30 days. TGs, TC, LDL-c, and AI were significantly reduced while HDL-c, SOD, and GPx levels rose to a considerable extent. After subjecting to acute toxicity testing, the extracts were found to be safe. The observations suggest antihyperlipidemic and antioxidant potential of P. emodi in high-fat diet induced hyperlipidemic/oxidative stressed rats.
