紫苏叶提取物对高脂血症家兔血脂及脂质过氧化的影响（英文）

[Objective] The preventive and therapeutic effects of Folium perillae extract(FPE)on hyperlipemia induced by feeding rabbit with high fat forage were observed.[Method] The high fat and cholesterol diet were adopted to create the hyperlipemia model of rabbit.The rabbits were randomly and equally divided into 5 groups which were NC(normal control)group,HLM(high lipid model)group,LFPE,MFPE and HFPE group(low,middle,high dosage of FPE were 0.17 g/kg,0.5 g/kg and 1.5 g/kg respectively).The contents of TC,TG,LDL-C,HDL-C,MDA and the activity of SOD in serum were detected respectively.[Result] The three FPE groups could decrease the contents of TC,TG,LDL-C,MDA significantly(P<0.01)compared with these of HLM group,and the contents of HDL-C(P<0.01))and the activity of SOD(P<0.05)in serum was increased significantly.[Conclusion] FPE could regulate blood-fat and counteract lipid peroxidation.     

Effects of Monoclonal Antibody Against Adipocyte-Specific Membrane Protein on Lipid Metabolism in Pigs

This study was to investigate the regulation of monoclonal antibodies against adipocyte membrane proteins （McAb） on lipid metabolism in pigs. Forty Landrace x Saba pigs were randomly divided into eight groups; the control group was given 10 mL saline and the treat groups were given monoclonal antibody against adipocyte-specific membrane protein with 0.1, 0.5, and 1.0 mg kg-I body weight at 15 and 60 kg body weight, respectively, by intraperitoneal injection. The results showed that McAb could increase, significantly, serum lipoprotein lipase activity and reduce serum nonesterified fatty acid （NEFA） content. Meanwhile, McAb increased content of serum lipid, triglyceride （TG）, cholesterol （CHO）, high density lipoprotein （HDL）, and low density lipoprotein （LDL） both at 15 and 60 kg body weight. However, McAb affected more significantly the lipid metabolism at 15 kg body weight than at 60 kg body weight. Moreover, this effect of McAb on lipid metabolism exhibited dose-dependent effect. These results suggested that this monoclonal antibody increased lipase activity, promoted lipolysis, and utilization of lipid so that McAb could be applied to restrain excessive fat deposition in porcine production through the regulation of fat metabolism.     

Effects of Allicin on Lipid Metabolism and Antioxidant Activity in Chickens

To investigate the effects of allicin on chickens＇ lipid and antioxidant performance, Hy-laying hens＇ diets were replenished with 0 mg · kg-1, 50 mg · kg-1, 100 mg · kg-1, and 150 mg · kg-1 allicin for 42 days, respectively. The alanine aminotransferase（ALT）, aspartate aminotransferase（AST）, triglyceride（TG）, total cholesterol（TCHO）, high density lipoprotein（HDL）, and low density lipoprotein（LDL） levels were measured in chicken serum. Superoxide dismutase（SOD）, glutathione peroxidase（GSH-Px） activity and malondialdehyde（MDA） levels were measured in chicken serum and liver tissue homogenate. The results showed that the supplement dose of allicin tested did not significantly change the activity of ALT or AST（P〉0.05）; TG and CHOL levels decreased with the increase of allicin additive doses, and the difference between treatment groups and CG was significant（P〈0.05）, and there was the best effect with 100 mg · kg-1; allicin significantly reduced the content of MDA, and increased SOD and GSH-Px activities compared with CG（P〈0.05）, and 100 mg · kg-1 of allicin resulted in the strongest SOD and GSH-Px activity. The antioxidant function test results of liver tissue homogenate were consistant with that of serum. Our findings indicated that allicin could enhance antioxidant capacity and reduce blood lipid level in chickens and 100 mg · kg-1 was the optimal amount of allicin additives.     

The Influence of Red Wine on Lipid of Golden Hamsters Plasma

This experiment was conducted on 50 male golden hamsters, which were divided into five groups. Each group contained 10 hamsters： red wine group, alcohol-free red wine group, alcohol group, hypedipidemia group, and control group. During the four-week regime, all the hamsters were fed with a high cholesterol diet, except the control group. After completion of the trial, the plasma lipid levels and lipid peroxidation contents were determined in the golden hamsters, and the morphological variation in liver cells was investigated with electron microscopy. The results showed that concentrations of TC and TG in red wine, alcohol-free red wine, and alcohol groups had decreased dramatically. Compared with the hyperlipidemia group, the levels of LDL-C had significantly decreased in other groups, but not the HDL-C. Consumption of red wine, alcohol-free red wine, and alcohol, had no significant effects on Apo A1 and Apo B. Red wine, alcohol-free red wine, and alcohol significantly decreased the contents of MDA in hamsters. The experiment demonstrated that red wine could ameliorate the incidence of atherosclerosis （AS） via reducing serum TC, TG, LDL-C, and the compounds in red wine had synergic effects.     

Effects of External Chemical Regulation on Bt Transgenic Cotton Plants under Combined Stress of High Temperature and Water Deficit

[Objective] The study aimed to find a possible way to combat or alleviate the negative effects caused by high temperature and water deficit at the growth stage of peak boll-setting.[Method] With Bt transgenic cotton GK22 as the test cultivar,a potted experiment was carried out to investigate the effects of the regulation of external substances(the water solutions of pix,urea and their mixture) on the physiological parameters,insecticidal protein content,yield and yield component of cotton plants in artificial climate chambers treated with high temperature and water deficit.[Result] The application of external pix,urea or their mixture was effective in stabilizing the physiological parameters of cotton plants,insecticidal protein content,yield and yield components.Compared with the exclusive application of pix and urea,the mixture of pix and urea played the most effective role in stabilizing the content of chlorophyll,soluble sugar and insecticidal protein,alleviating the increase of the content of free amino acids and proline,and increasing boll number per plant,boll weight and seed cotton yield.[Conclusion] The water solutions of pix,urea or their mixtures can be used to combat or alleviate the stress of high temperature and water deficit if they are sprayed onto cotton plants prior to stress occurrence.     

Effects of Imidapril on Venous Blood Gas Values in Broiler Chickens Exposed to Low Ambient Temperature

ObjectiveThis study was designed to evaluate the effects of imidapril on blood gas parameters in broiler chickens. MethodTwenty-four chickens were randomly divided into three groups (n=8), control group, low temperature group and imidapril group. Chickens in low temperature group and imidapril group were exposed to low ambient temperature (12-18 ℃) from age at 14 d to 45 d, whereas the control group was exposed to 24-30 ℃; chickens in imidapril group were gavaged with imidapril (3 mg/kg) once daily for 30 d. At age of 45 d, blood was taken from wing vein and blood gas parameters were evaluated by blood gas analyzer in Luoyang Central Hospital Affiliated to Zhengzhou University. ResultImidapril significantly increased hematocrit (HCT) and total hemoglobin content (T HBC ) and blood Na concentration in broiler chickens exposed to low ambient temperature. No significant differences were observed in pH, P CO 2 , P O 2 , K + , Ca 2+ , HCO 3-, HCO 3std , T CO 2 , BE and SO 2c . ConclusionImidapril increases hematocrit, total hemoglobin content and blood Na + concentration in chickens exposed to low ambient temperature.

By t test, the indexes, except hematocrit, decreased significantly after treatment (P<0.05) and reached the status of post partum healthy cows. The hemorheological indexes didn't change significantly in the control group before and after treatment. [Conclusion] Yizhikang powder could significantly improve blood flow state and reduced the occurrence of qi stagnation and blood stasis in perinatal period.     

High plant density increases seed Bt endotoxin content in Bt transgenic cotton

Plant density is the cultivation practice usually employed to manipulate boll distribution, boll setting and yield in cotton production. In order to determine the effect of plant density on the insecticidal protein content of Bacillus thuringiensis(Bt) cotton plants, a study was conducted in Yangzhou University of China in 2015 and 2016. Five plant densities(PD1–PD5, representing 15 000, 30 000, 45 000, 60 000, and 75 000 plants ha–1) were imposed on two Bt cotton cultivars, Sikang 1(the conventional cultivar, SK-1) and Sikang 3(the hybrid cultivar, SK-3). The boll number per plant, boll weight and boll volume all decreased as plant density increased. As plant density increased from 15 000 to 75 000 plants ha~(–1), seed Bt protein content increased, with increases of 66.5% in SK-1 and 53.4% in SK-3 at 40 days after flowering(DAF) in 2015, and 36.8% in SK-1 and 38.6% in SK-3 in 2016. Nitrogen(N) metabolism was investigated to uncover the potential mechanism. The analysis of N metabolism showed enhanced soluble protein content, glutamic-pyruvic transaminase(GPT) and glutamate oxaloacetate transaminase(GOT) activities, but reduced free amino acid content, and protease and peptidase activities with increasing plant density. At 20 DAF, the seed Bt toxin amount was positively correlated with soluble protein level, with correlation coefficients of 0.825** in SK-1 and 0.926** in SK-3 in 2015, and 0.955** in SK-1 and 0.965** in SK-3 in 2016. In contrast, the seed Bt protein level was negatively correlated with free amino acid content, with correlation coefficients of –0.983** in SK-1 and –0.974** in SK-3 in 2015, and –0.996** in SK-1 and –0.986** in SK-3 in 2016. To further confirm the relationship of Bt protein content and N metabolism, the Bt protein content was found to be positively correlated with the activities of GPT and GOT, but negatively correlated with the activities of protease and peptidase. In conclusion, our present study indicated that high plant density elevated the amount of seed Bt protein, and this increase was associated with decreased boll number per plant, boll weight and boll volume. In addition, altered N metabolism also contributed to the increased Bt protein content under high plant density.     

Effects of Hypergravity on Salt Tolerance of Wheat Seedlings

[Objective] The study aimed to reveal the effects of hypergravity on salt tolerance of wheat seedlings. [Method] The seed germination rate (Gr) and germination index (Gi) of wheat seedlings were measured under hypergravity of 600×g or 1 000×g for 4 h and under the stress of 0.4% or 0.9% salt solution. The catalase (CAT) activity and malondialdehyde (MDA) content of wheat seedlings were also measured under 0.4% salt stress. [Result] Compared with seedlings in CK group (no hypergravity or salt stress),the Gr and Gi of the seedlings in salt stress treatment decreased to different extents; while the Gr and Gi of the seedlings in treatment group (hypergravity and salt stress) increased compared with that in salt stress group. CAT in seedlings of hypergravity treatment was higher than that of CK group and 0.4% salt treatment group,meanwhile the MDA showed an opposite result. [Conclusion] Hypergravity could enhance the salt resistance of wheat in specific range,and hypergravity of 600×g for 4 h performed better than that of 1 000×g for 4 h.
