Changes of Hematological and Hemorheological Parameters in Rabbits with Hypercholesterolemia. Metabolites 2021; 11:metabo11040249. [PMID: 33920738 PMCID: PMC8072928 DOI: 10.3390/metabo11040249] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2021] [Revised: 04/15/2021] [Accepted: 04/16/2021] [Indexed: 12/19/2022] Open
Abstract
Hypercholesterolemia plays an important role in the development of atherosclerosis, leading to endothelial dysfunction, ischemic events, and increased mortality. Numerous studies suggest the pivotal role of rheological factors in the pathology of atherosclerosis. To get a more detailed hematological and hemorheological profile in hypercholesterolemia, we carried out an experiment on rabbits. Animals were divided into two groups: the control group (Control) was kept on normal rabbit chow, the high-cholesterol diet group (HC) was fed with special increased cholesterol-containing food. Hematological parameters (Sysmex K-4500 automate), whole blood and plasma viscosity (Hevimet-40 capillary viscometer), red blood cell (RBC) aggregation (Myrenne MA-1 aggregometer), deformability and mechanical stability (LoRRca MaxSis Osmoscan ektacytometer) were tested. The white blood cell and platelet count, mean corpuscular volume, and mean corpuscular hemoglobin were significantly higher in the HC group, while the RBC count, hemoglobin, and hematocrit values were lower than the Control data. Viscosity values corrected to 40% hematocrit were higher in the HC group. The RBC aggregation significantly increased in the HC vs. the Control. The HC group showed significantly worse results both in RBCs' deformability and membrane stability. In conclusion, the atherogenic diet worsens the hematological and macro- and micro-rheological parameters, affecting blood flow properties and microcirculation.

Meat Sci 2018; 145:292-299. [PMID: 30007175 DOI: 10.1016/j.meatsci.2018.07.002] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2018] [Revised: 06/27/2018] [Accepted: 07/03/2018] [Indexed: 10/28/2022]
Abstract
Since animal diets have a strong influence on meat quality, a comparative study on farmed brown hares and domestic rabbits offered the same diet was undertaken to assess the physical and chemical properties of their meat. Ten brown hares and ten domestic rabbits were used to characterize the traits of meat from the foreleg, hind leg, and Longissimus lumborum muscles. The study indicated higher protein content in hare meat than in rabbit meat. The meat of hares had a concentration of heme iron that was more than twice as high as that of rabbits. Lower SFA and MUFA content and higher PUFA content contributed to the superior PUFA/SFA ratio in hares. An unfavorable n-6/n-3 ratio but superior atherogenic and thrombogenic indices was observed for hare meat. The higher TBARS of hares indicated a higher susceptibility of hare meat to lipid oxidation. Hare meat was also characterized by a higher water holding capacity and higher color indices (redness and chroma).

The effects of seed from Linum usitatissimum cultivar with increased phenylpropanoid compounds and hydrolysable tannin in a high cholesterol-fed rabbit. Lipids Health Dis 2018; 17:76. [PMID: 29631590 PMCID: PMC5891892 DOI: 10.1186/s12944-018-0726-4] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2018] [Accepted: 03/28/2018] [Indexed: 01/19/2023] Open
Abstract
Background Dietary fat is considered one of the most important factors associated with blood lipid metabolism and plays a significant role in the cause and prevention of atherosclerosis that has been widely accepted as an inflammatory disease of the vascular system. The aim of the present study was to evaluate the effect of genetically modified flaxseed (W86) rich in phenylpropanoid compounds and hydrolysable tannin in high cholesterol-induced atherosclerosis rabbit models compared to parental cultivar Linola. Methods Twenty-Eight White New Zealand white rabbits aged 6 months were randomly divided into four groups, control group, high cholesterol group (10 g/kg), Linola flaxseed group (100 g/kg) and W86 flaxseed group (100 g/kg). The rabbits were fed a normal diet or a high cholesterol diet for 10 weeks. Levels of blood lipids, hematological values, total antioxidative status and superoxide dismutase activity in serum were determined. Moreover, body weight and feed intake were measured after sixth and tenth weeks. After each stage of the experiment atherogenic indexes (non-HDL-C/HDL-C, LDL-C/HDL-C, and atherogenic index of plasma) was calculated. Results The intake of a dyslipidaemic diet negatively influenced lipid profile in rabbits at the 10 weeks of feeding. W86 flaxseed significantly decreased total cholesterol, LDL-C, VLDL-C and TG serum levels in cholesterolemic rabbits compared with parental Linola after 10 weeks. Atherogenic indexes decreased over time with a significant difference between the diets and they were the best for W86 flaxseed. Similarly, the experimental addition of W86 significantly decreased atherogenic predictors such as heterophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, and the mean platelet volume-to-lymphocyte ratio. In rabbits, W86 flaxseed increased the activity of superoxide dismutase and total antioxidative status compared to Linola. Conclusions Results of the presented study suggest that the addition of W86 flaxseed alleviate serum lipid changes in high cholesterolemic diet-administered rabbits. W86 flaxseed significantly reduced atherogenic indexes, as compared with the Linola and indicate that W86 flaxseed more effectively red CVD risk factors during hypercholesterolemia. Moreover, the presented result suggested that W86 flaxseed can be a part of a heart-healthy and antiatherogenic diet for the human.

PLoS One 2017; 12:e0182467. [PMID: 28877164 PMCID: PMC5587228 DOI: 10.1371/journal.pone.0182467] [Citation(s) in RCA: 36] [Impact Index Per Article: 5.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2017] [Accepted: 07/19/2017] [Indexed: 12/15/2022] Open
Abstract
The radix of Scutellaria baicalensis (SB) is a herb widely used in traditional Chinese medicine to treat metabolic diseases. Several main components, including baicalin and wogonoside, possess anti-dyslipidemia, anti-obesity and anti-diabetic effects. We hypothesized that co-administration of SB extract and metformin exerts a better effect on obesity-induced insulin resistance and lipid metabolism than treatment with metformin alone. We compared the effect of metformin (100 mg/10 mL/kg/day) alone with co-administration of metformin (100 mg/5 mL/kg/day) and SB extract (200 mg/5 mL/kg/day) on Otsuka Long Evans Tokushima Fatty rats, a useful model of type II diabetes with obesity, and used Long-Evans Tokushima Otsuka rats as a control. Weight, fasting glucose, oral glucose tolerance test, intraperitoneal insulin tolerance test, and serum total cholesterol were measured after 12 weeks of drug administration. We observed a synergetic effect of metformin and SB on lowering cholesterol level by excretion of bile acid through feces. We found that this accompanied activation of FXR, CYP7A1 and LDLR genes and repression of HMGCR in the liver. Although there were no significant changes in BSH-active gut microbiota due to high variability, functional prediction with 16S sequences showed increased primary and secondary bile acid biosynthesis in the combination treatment group. Further study is needed to find the specific strains of bacteria which contribute to FXR-related cholesterol and bile acid regulations.

Abstract
The aim of this study was to examine the effects of a one-week feed restriction of different intensities on haematological and biochemical blood indices at the end of the feed restriction and during the realimentation period in growing rabbits. Hyplus rabbits weaned at 35 days of age (n = 195) were divided into three groups: rabbits fedad libitum(AL) and groups with reduced feed of 50 g (R50) or 65 g (R65) per rabbit per day from 42 to 49 days of age. At the end of the feed restriction and in the following period, haematological and biochemical blood indices were measured at weekly intervals. The live weight at 70 days of age was lower (P≤ 0.001) in restricted rabbits (–14.5% and –15.5% for group R50 and R65, respectively, compared to AL). Feed restriction significantly (P≤ 0.011) decreased the number of erythrocytes (–6.2% and –7.4% for group R50 and R65, respectively, compared to AL) and haemoglobin content (P≤ 0.008). The mean corpuscular volume increased (P≤ 0.033) in restricted rabbits. Interaction of the feeding regime and age (P≤ 0.007) was observed in cholesterol with the highest concentration in R50 at 56 days (4.41 mmol/l) and the lowest in R65 at 70 days and in AL at 63 days of age (1.30 mmol/l). The concentration of non-esterified fatty acids (P≤ 0.003) and triacylglycerides (P≤ 0.048) were significantly lower in restricted rabbits. It could be concluded that feed restriction influenced mainly erythrocytes and haemoglobin. The changes in biochemical blood characteristics suggest the restriction did not affect protein metabolism, however, results indicate lipid depletion in restricted rabbits.

Abstract
Background The health of chickens and the welfare of poultry industry are central to the efforts of addressing global food security. Therefore, it is essential to study chicken immunology to maintain and improve its health and to find novel and sustainable solutions. This paper presents a study on investigation of the effect of Scutellaria baicalensis root (SBR) on the immune response of broiler chicken, especially on lymphocytes and heterophils reactivity, regarding their contribution to the development of immunity of the chickens. Methods The 121-day-old Hubbard Hi-Y male broiler hybrids were randomly assigned to four treatment groups, three SBR supplemented groups (0.5, 1.0, and 1.5% of SBR) and one control group. Each treatment was replicated five times with six birds per replicate pen in a battery brooder. Blood was collected after 3rd and 6th wk of the experiment, and hemoglobin and hematocrit values were determined, as well as total leukocyte count and differential count were performed. Nitroblue tetrazolium test and phagocytosis assay as nonspecific immune parameters and humoral immune responses to the antigenic challenge by sheep red blood cells were performed. Moreover, the ability of peripheral blood lymphocytes to form radial segmentation (RS) of their nuclei was analyzed. Body weight and relative weight of spleen, liver, and bursa of Fabricius were recorded. Results Results showed that mean heterophile/lymphocyte ratio increased in the SBR groups compared to the control group and the blood of the chickens showed lymphocytic depletion. The results also demonstrated that the relative weight of bursa of Fabricius and spleen in groups fed with SBR significantly decreased compared to the control group. This study also showed that the addition of SBR significantly inhibited the formation of RS of nuclei compared to some cytotoxic substances. Conclusion We found that SBR supplementation should be carefully evaluated when given to poultry. The excess intake of SBR supplementation may cause immunologic inhibition and may negatively affect the development of immune organs. SBR has inhibited the formation of radial segmentation nuclei showing antimetastatic properties and also the phagocytosis of chicken heterophils.

A new genotype of flax (Linum usitatissimum L.) with decreased susceptibility to fat oxidation: consequences to hematological and biochemical profiles of blood indices. JOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE 2017; 97:165-171.

Abstract
BACKGROUND Flaxseed is an alternative to marine products that provide the traditional dietary sources of ω-fatty acids. A new genotype of flax, W92, is rich in natural antioxidants as well as having a reduced content of α-linolenic acid and therefore shows decreased susceptibility to fat oxidation. The objective of this study was to evaluate the effect of a diet supplemented with W92 flaxseed on hematological and biochemical blood indices. RESULTS A positive impact of diet with the addition of flaxseed was observed on erythrocyte indices, including red blood cell (RBC), hematocrit (HCT), mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) values. There were no significant differences for white blood cell (WBC), total protein and glucose values. Aspartate aminotransferase and alanine aminotransferase estimations in serum were also carried out and no obvious toxicity to the liver was shown. Moreover, a lipid profile was performed in serum samples and a decrease in total cholesterol and low-density lipoprotein cholesterol (LDL-C), accompanied by an increase in high-density lipoprotein cholesterol (HDL-C), was observed in rabbits fed flaxseed diets. CONCLUSION Based on the results obtained, it appeared that the inclusion of a new genetically modified type of flaxseed in the diet altered cholesterol metabolism and could reduce the possibility of cardiovascular diseases. Diet enrichment with W92 flaxseed may be a solution to the health issues that are a result of improper diet in humans and animals. © 2016 Society of Chemical Industry.

Abstract
The aim of the present work was to investigate the effect of Rhus coriaria L. inclusion to the diet on some biochemical, haematological parameters and the level of antioxidant status of male rabbits. Adult rabbits were divided into five groups: one control (C) and four experimental groups. Experimental animals received sumac per os in feed in various doses (0.50%, 0.75%, 1.00% and 1.50%) for 90 days. Significant increase in PDWc (platelet distribution width) in E3 group when compared with control group was recorded. Sumac administration resulted in decreased cholesterol levels in all experimental groups vs. control group. Significantly lower level of cholesterol was found in E4 group with highest dose of sumac (1.50%). Higher values of total antioxidant status (TAS) and albumins were observed in all experimental groups in comparison with control group. A significant increase in TAS was detected in group E1 and E4. Concentrations of albumins were significantly higher in groups E3 and E4 vs. control group. Sumac administration had no significant effect on bilirubin content. In conclusion, these results show a positive effect of sumac consumption on antioxidant status and cholesterol level in adult male rabbits.
