The hypolipidemic effect and anti-oxidative activity of seabuckthorn marc flavonoids (SMF) on hyperlipidemic rats was investigated. The rats were divided into 5 groups, including normal control group, hyperlipidemic model control group and 3 different doses of SMF groups i.e. 3.0 mg/kg·bw, 30.0 mg/kg·bw, 90mg/kg·bw, respectively. The SMF was given orally for 35 days. After the treatment, the body, fat and liver weights of rats were weighed. The content of serum total triglycerides (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C) and the activity of lipid metabolism and anti-oxidative enzyme were determined. The levels of serum lipids in hyperlipidemic rats fed with SMF were significantly lower than model control group. The activities of hepatic lipase (HL), lipoprotein lipase (LPL), lipidase (LPS), superoxide dismutase (SOD), glutathione (GSH) in liver were increased, while the contents of malondialdehyde (MDA) were decreased in SMF groups. The results indicate that SMF has significantly hypolipidemic effects and antioxidant activity.

Hibiscus Sabdariffa

Aim of the Study: This study was undertaken to ascertain if Hibiscus sabdariffa extract can affect the lipid profile (Total cholesterol (TC), triglycerides (TG), high density lipoprotein (HDL), very low density lipoprotein (VLDL), and low density lipoprotein (LDL)) levels in a paracetamol- induced hepatotoxicity using albino Wistar rat as a model. Materials and Methods: Thirty (30) rats used for this study were divided into three groups. Group A (n=10) served as control. Group B (n=10) was administered paracetamol only at a dose of 750 mg/kg body weight. Group C (n=10) was administered paracetamol (dose 750 mg/kg body weight) and aqueous extract of H. sabdariffa (dose 10 ml/kg body weight) of the animal for 3 weeks. All animals were allowed free access to clean drinking water and normal rat chow. Results: Results of the study revealed that TC was significantly lower (p<0.05) in the paracetamol + H. sabdariffa-treated group as compared to paracetamol-treated group and control respectively. Similar trend was observed with TG, VLDL-c, LDL-c and HDL-c. However, the decrease in HDL-c was not statistically significant when compared to control. Conclusion: The presence of bioactive constituents vis; anthocyanins, flavonoids, polyvenols and free radical scavenging properties in H. sabdariffa enabled a hypolipidemic effect on the animals by lowering the levels of serum TG, VLDL-c, LDL-c despite challenge on the liver. However, it was unable to produce significant effect on HDL concentration -very important cholesterol required in high level to maintain homeostasis inside the body. This may be due to the challenge on the liver as a result of the paracetamol abuse.

To study the regulation effect of apple polyphenol on fat metabolism in mice. The mice were randomly divided into 5 groups, except the basic control group, the other 4 groups were given high fat diet, body weight was measured once a week, and the obesity model was established. The basal control group and the obesity model group were intragastrically given normal saline (4.2mg/(kgbw.d), The three dose groups were gavaged separately with apple polyphenol 4.2, 8.4, 12.6 mg/(kg bw. d). After 4 consecutive weeks, the body weight of mice, the contents of total cholesterol (TC), total triglyceride (TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), malondialdehyde (MDA) in serum and the activities of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), liver lipase (HL) and lipoprotein lipase (LPL) in serum. should be measured respectively. Apple polyphenol can significantly reduce the body weight, TG, LDL-C, TC and MDA contents, coupled with the atherosclerosis index (AI) of obese mice. It can increase the serum HDL-C content of obese mice, and effectively increase the activities of SOD, GSH-Px, HL and LPL in mice. Apple Polyphenol can reduce blood lipid and prevent atherosclerosis via regulating fat metabolism in mice.

Objective: To investigate the effect of antibiotics and/or probiotics on broiler performance, some serum metabolites, cecum microflora composition, and ileum histomorphology under the Egyptian conditions. Design: Randomized controlled experimental study. Animals: Two hundred forty 1-day-old Ross (308) chicks were reared till 35 days of age. Procedures: The birds were randomly allocated into four main groups: a control diet without additives (CON); probiotic (Lactobacillus acidophilus) supplemented diet (PRO); antibiotic (Avilamycin) supplemented diet (ANT) and a mix group (AP) that received antibiotic in the diet form 1 to 4 days of age and treated during the rest of the experimental period with probiotics. Results: Chickens fed on probiotic or antibiotic diets had linear improvement in live body weight (LBW) and feed conversion ratio (FCR) compared with the control group, while the best LBW and FCR were in the AP group. An improvement in the nutrient digestibility was observed in the probiotic added groups (PRO and AP). Serum cholesterol and low-density lipoprotein cholesterol contents decreased when antimicrobial (probiotic or antibiotic) supplementations were used, while there was an increase in high-density lipoprotein cholesterol contents, serum total protein, and albumin levels. Among all groups, cecum Clostridium perfringens and Escherichia coli counts decreased; however, there was an increase in Lactobacillus count compared to the control group. In probiotic supplemented groups (PRO and AP), a significant (P<0.05) improvement in ilea architecture. Conclusion and clinical relevance: Using probiotic after initial treatment with an antibiotic in broiler diets had a positive effect on broiler growth performance, gut health (improved cecum microbial populations and ileum histomorphology), and nutrient digestibility.

The metabolic fitness (MF) is a component of athletes’ physical conditioning. This study aims to investigate the effects of quercetin supplementation on Turkish Junior athletes’ lipid and protein metabolism relating to MF after one month classic boxing training. Totally 20 voluntary junior male athletes were separated into two equal groups as the experimental group (EG) and control group (CG). The participants were supplemented with 500 mg quercetin fifteen minutes before each workout in one month boxing training program. Blood samples during pre and post training were taken from athletes in order to determine metabolic fitness related parameters. Lipid profile contains low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), trigliserid (TG), total cholesterol (TC) variables while protein metabolism includes the albumin, total protein, direct bilirubin and total bilirubin parameters. The Mann Whitney U analyzes were used for comparison of the means between experimental and control groups during pre and posttest and between pre and post test results in experimental and control groups. This study showed that EG had a similar physical characteristic with CG. There were significant decrease in TC and LDL-C and an increase in HDL-C in EG while there was only significant increase in HDL-C of in controls. A significant difference of HDL-C was observed between EG and CG during pretest. In other side, TC and LDL-C and HDL-C were significantly differentiated between EG and CG during posttest. Conclusion: it can be concluded that quercetin plays an important role on lipid metabolism not protein.

Dyslipidemia is a metabolic disorder that is characterized with an elevation in the cholesterol serum levels that can be treated with various hypolipidemic drugs like rosuvastatin. The present study was undertaken to determine and evaluate the hypolipidemic effect of milk thistle seeds extract in comparison with rosuvastatin and the combination of both for the treatment of dyslipidemia in rats. Also its effect on blood glucose levels on experimentally induced dyslipidemic rats. In vivo studies were conducted on wister albino laboratory rats, in which 49 rats were induced to be dyslipidemic by a daily intragastric administration of cholesterol (2 g/kg). The induction of dyslipidemia was evaluated by comparing these rats with a negative control group that was composed of 10 healthy rats. Then, after one month dyslipidemia was induced in 49 rats that were divided into 6 groups, as the following; positive control group (n=9) received cholesterol (2 g/kg) for another one month, and the other five groups each of 8 rats continued to receive cholesterol (2 g/kg) for one month along with therapy as; rosuvastatin low dose (RL) group received 10 mg/kg, rosuvastatin high dose (RH) group received 20 mg/kg, milk thistle (MT) group received 7.15 mg/kg, (RL+MT) group received a combination of 10 mg/kg of rosuvastatin and 7.15 mg/kg of milk thistle, and (RH+MT) group received a combination of 20 mg/kg of rosuvastatin and 7.15 mg/kg of milk thistle. The statistical results of biochemical analysis showed that all the studied therapeutic protocols whether given alone; RL, RH, and MT or in a combination; RL+MT and RH+MT led to a significant (p≤0.05) hypolipidemic effect that reduced the total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL) and very low density lipoprotein (VLDL) and increased the high density lipoprotein (HDL) cholesterol levels. In conclusion, all therapeutic protocols were effective in treating dyslipidemia, as they all reduced the TC, TG, LDL, and VLDL, and increased the HDL cholesterol significantly (p≤0.05). Furthermore, we found that milk thistle can be used in the management of dyslipidemia, as it has a hypolipidemic effect. Also, the addition of milk thistle to rosuvastatin therapy reduced the risk of developing diabetes mellitus (DM), as it has a glucose modulating activity either when it was given alone or in combination with rosuvastatin. Moreover, the combination of milk thistle and rosuvastatin was of a great benefit, as it gave an intensive goal of therapy than each one alone in altering all lipid profile parameters.

Abstract: The objective of this work was to evaluate the effect of a dietary supplementation with soy lecithin (SL) on the productive performance and blood constituents of rabbit females and their offsprings. A total of 40 rabbits does were distributed into four treatments: control group, no dietary SL inclusion; and three groups with 0.5, 1.0, and 1.5% SL inclusion in the diets. The inclusion of 1.5% SL increased the count of blood cells and hemoglobin concentrations; 0.5-1.0% SL reduced the total cholesterol levels in the blood, as well as the low-density lipoprotein-cholesterol and the activities of the enzymes alkaline phosphatase, aspartate aminotransferase, and alanine aminotransferase, but increased the levels of total lipids, triglycerides, high-density lipoprotein-cholesterol, and the activities of the antioxidant enzymes. Supplementation with 1.0-1.5% SL resulted in higher milk production and heavier litters. Soy lecithin supplementation at 1% improves the physiological parameters and increases the milk production of rabbit does, also improving the performances of their offsprings.

Although over-nutrition from overfeeding-induced obesity is known to be highly associated with metabolic and immunological disorders in humans, little is known about overfeeding-induced obesity in fish farming. The purpose of this study was to investigate changes in immuno-physiological parameters, to better understand the potential risk of overfeeding–induced obesity in fish. Commercial feed was provided to fish in the overfed group until they refuse to eat, but fish in the control group was fed with the feed at 1% bodyweight per day. The hemato-serological, histological, and immunological changes were observed at weeks 2 and 8. Rainbow trout leukocytes were co-incubated with oxidized low-density lipoprotein (OxLDL), and the phagocytes engulfing the OxLDL and the presence of apoptotic cells were evaluated. The body weight, body mass index (BMI), and hepatosomatic index (HSI) index were significantly higher in the overfed group, and high lipid accumulation and fatty changes were also observed in their livers, indicating that the feeding regime used in this study led to overfeeding-induced obesity. Likewise, much higher numbers of and larger vacuoles were observed in overfed fish macrophages, showing unclear boundaries between the cytoplasm and extracellular space. In the overfed group, the expression of IL-10, HSP70, TLR2, and CD36 was significantly higher, and lymphocyte apoptosis was more evident, indicating that overfeeding-induced obese fish might have immunologic disorders. This was the first study to demonstrate that overfeeding-induced obesity could cause an immune-physiological imbalance in rainbow trout, making them more vulnerable to infectious diseases and various stressful conditions. This study will contribute to improvements in fish nutrition, feeding practices, fish nutrition, and disease prevention in the aquaculture industry.

Objective: To evaluate the antioxidant and antihyperlipidaemic effect of methanol extracts of Asteracantha longifolia and Pergularia daemia leaf in alloxan induced diabetic rats. Methods: Swiss albino rats were made diabetic by a single dose of alloxan monohydrate (150 mg/kg i.p.). Blood glucose levels and body weights of rats were measured using on weekly intervals i.e day 0,7,14 and 21 after daily administration of both extracts at dose 200 mg/kg bw. Other biochemical parameters such as serum cholesterol, triglycerides, low density lipoprotein-cholesterol, very low density lipoprotein-cholesterol, high density lipoprotein-cholesterol, phospholipids and serum protein, albumin, globulin levels were also measured at the end of study. The antioxidant enzymes (CAT, SOD & GSH) were also measured in the diabetic rats. Results: In the acute toxicity study, methanol extract of both plants were non-toxic at 2000 mg/kg in rats. The increased body weight, decreased blood glucose and other biochemical parameters level were observed in diabetic rats treated with methanol extracts of both plants compared to diabetic control rats. The antioxidant activity of both plant extracts were also exhibited significant activity. In diabetic rats, methanol extract of both plants administration, altered lipid profiles were reversed to near normal than diabetic control rats. Conclusions: Methanol extract of both plants (Asteracantha longifolia and Pergularia daemia) leaf possesses significant antioxidant and antihyperlipidaemic activity in diabetic rats.
