This study was to investigate the effects of the combination of deoxynivalenol (DON) and zearalenone (ZON) on pigs. Twenty-four weaning piglets were divided into a control group fed a diet free of mycotoxins and a toxin group fed a diet containing 1 mg/kg DON and 250 microgram/kg ZON. The results showed that supplementation of DON and ZON in diets had extensive effects on pigs. More specifically, DON and ZON caused levels of total protein, albumin, and globulin in sera to decrease (p < 0.05) by 14.5%, 6.5% and 11.3%, respectively, and at the same time increased (p < 0.05) the serum enzyme activities of gamma-glutamyltransferase, aspartate aminotransferase and alanine aminotransferase by 72.0%, 32.6% and 36.6%, respectively. In addition, DON and ZON decreased (p < 0.05) the level of anticlassical swine fever antibody titers by 14.8%. Real-time PCR showed that DON and ZON caused the mRNA expression levels of IFN-gamma, TNF-alpha, IL-2, to decrease (p < 0.05) by 36.0%, 29.0% and 35.4%, respectively. Histopathological studies demonstrated that DON and ZON caused abnormalities in the liver, spleen, lymph nodes, uterus, and kidney. The concentrations of DON and ZON used in this study are in line with the published critical values permitted by BML. Our study clearly put the standard and adequacy of safety measures for these toxins into question. The authors suggest that with the increasing availability of cellular and molecular technologies, it is time to revisit the safety standards for toxins in feeds so as to make feeds safer, providing consumers with safer products.

Objective: This research was performed to evaluate the effect of tebuconazole (TBZ) on reproductive organs of male rats and to assess the protective role of combined essential trace elements in alleviating the detrimental effect of TBZ on male reproductive function. Methods: For this purpose, 48 rats were exposed to 100 mg/kg TBZ, TBZ supplemented with zinc (Zn), selenium (Se), copper (Cu), and iron (Fe), TBZ + (Se + Zn); TBZ + Cu; or TBZ + Fe. The experiment was conducted for 30 consecutive days. Results: TBZ caused a significant perturbation in mineral levels and reduction in reproductive organs weights, plasma testosterone level, and testicular antioxidant enzyme activities. The TBZ-treated group also showed a significant increase in sperm abnormalities (count, motility, and viability percent), plasma follicle-stimulating hormone and luteinizing hormone concentrations, lipid peroxidation, protein oxidation, and severe DNA degradation in comparison with the controls. Histopathologically, TBZ caused testis impairments. Conversely, treatment with trace elements, in combination or alone, improved the reproductive organ weights, sperm characteristics, TBZ-induced toxicity, and histopathological modifications in testis. Conclusion TBZ exerts significant harmful effects on male reproductive system. The concurrent administration of trace elements reduces testis dysfunction, fertility, and toxicity induced by TBZ.

OBJECTIVETo observe the effects of Tongxinluo Supermicro Powder on the nuclear factor-kappaB (NF-kappaB), inter-cell adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) expression in aorta of rabbits fed with high-lipid diet.

METHODSHealthy male New Zealand rabbits were randomly divided into 4 groups (n = 8 each): control group, model group, atorvastatin group (3 mg x kg(-1) x d(-1) per gavage), and Tongxinluo group (0.31 g x kg(-1) x d(-1) per gavage). At the end of 6 weeks, the expression of NF-kappaB, ICAM-1 and VCAM-1 were observed by immunochemistry methods, Western blotting and reverse transcription polymerase chain reaction (RT-PCR).

RESULTThe nuclear translocation of NF-kappaB in aortic endothelial cells and the gene expressions of NF-kappaB, ICAM-1 and VCAM-1 at protein and mRNA levels of the model group was significantly increased compared that in the control group (all P < 0.05), these effects could be significantly attenuated by atorvastatin and Tongxinluo Supermicro Powder (P < 0.01 vs. model group).

CONCLUSIONSSimilar as atorvastatin, Tongxinluo Supermicro Powder could relieve the process of atherosclerosis by decreasing the nuclear translocation of NF-kappaB and reducing the expression of ICAM-1, VCAM-1 in this model.

OBJECTIVETo study the effects of high-fat plus ethanol diet on myocardial ultrastructure in rats.

METHODS40 male SD rats in seventy-eight-week old were randomly divided into four groups: group A was control group, fed with common feedstuff; group B was high-fat diet group, freely foraging high-fat feedstuff; group C was ethanol group, the rats were intragastrically administered 60% ethanol solution twice a day by 1 ml/kg; group D was high-fat diet and ethanol group, the rats freely foraged high-fat feedstuff, and ethanol solution was intragastrically administered as before. After 12 weeks, blood samples were taken through jugular vein, the concentration of blood cholesterol (TG), triglycerides (TC), high-density lipoprotein (HDL), low-density lipoprotein (LDL), apolipoprotein A1 (Apo-A1), apolipoprotein B (Apo-B), and alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL) were determined. The cardiac index was also determined for all groups and the cardiac morphous were observed by high resolution Doppler ultrasound, and myocardial ultrastructure was observed by transmission electron microscope.

RESULTSAfter experiment, TG levels of groups A, B, C, D were (1.07 +/- 0.21), (2.34 +/- 0.72), (1.33 +/- 0.42) and (1.75 +/- 0.65) mmol/L, respectively (F = 8.323, P = 0.000); TC levels were (1.74 +/- 0.38), (5.66 +/- 1.74), (1.70 +/- 0.44) and (5.65 +/- 2.95) mmol/L, respectively (F = 13.670, P = 0.000); HDL levels were (0.65 +/- 0.11), (2.99 +/- 0.54), (0.52 +/- 0.13) and (2.06 +/- 0.26) mmol/L, respectively (F = 112.225, P = 0.000); LDL levels were (0.74 +/- 0.22), (1.87 +/- 0.90), (0.60 +/- 0.26) and (1.54 +/- 0.78) mmol/L, respectively (F = 7.318, P = 0.001); Apo-A1 levels were (0.25 +/- 0.10), (0.31 +/- 0.14), (0.21 +/- 0.05) and (0.36 +/- 0.11) g/L, respectively (F = 3.015, P = 0.047); Apo-B levels were (0.18 +/- 0.03), (0.11 +/- 0.04), (0.16 +/- 0.03) and (0.39 +/- 0.13) g/L, respectively (F = 15.621, P = 0.000); ALT levels were (111.25 +/- 20.18), (447.13 +/- 89.25), (173.13 +/- 44.01) and (198.25 +/- 39.81) U/L, respectively (F = 58.708, P = 0.000); AST levels were (105.50 +/- 9.99), (483.00 +/- 16.80), (120.75 +/- 5.09) and (276.88 +/- 10.48) U/L, respectively (F = 1906.624, P = 0.000);TBIL levels were (1.35 +/- 0.12), (1.66 +/- 0.18), (1.89 +/- 0.15) and (2.68 +/- 0.35)U/L, respectively (F = 55.006, P = 0.000); cardiac indexes were (3.02 +/- 0.22)%, (3.21 +/- 0.16)%, (3.26 +/- 0.26)% and (3.43 +/- 0.27)%, respectively (F = 16.150, P = 0.000). There were changes of cardiac morphous in group C and D, but not in group A and B; the myocardial ultrastructure was normal in Group A, but light to heavy changes were found in group B, C and D.

CONCLUSIONHigh-fat diet and excessive intake of ethanol significantly induce abnormal lipid metabolism. High-fat diet induces the changes of myocardial ultrastructure before cardiac morphous and electrocardiogram, and intake of ethanol changes cardiac muscle in microstructure and macroscopy. High-fat diet plus ethanol may worsen this injury farther.

Because linseed oil may influence maternal and fetal metabolisms, we investigated its role in the modulation of lipid metabolism in cafeteria diet-induced obese rats and their offspring. Female Wistar rats were fed control or cafeteria food, which were either supplemented or not supplemented with linseed oil (5%) for 1 month before and during gestation. At parturition, serum and tissue lipids and enzyme activities were analyzed. Cafeteria diet induced adverse metabolic alterations in both mothers and offspring. Linseed oil improved metabolic status. In conclusion, linseed oil displayed health benefits by modulating tissue enzyme activities in both obese mothers and their newborns.
