Abstract:
BACKGROUND:Fructus Zipiphi Jujubae,with certain cyclic adenosine monophosphate(cAMP) and cyclic guanosine monophosphate(cGMP),has effects on hypertension,diabetes,cancer and cardiogenic shock.But there has been rare report on the influence of Fructus Zipiphi Jujubae on blood lipid. OBJECTIVE:To study the effects of juice of Fructus Zipiphi Jujubae on body function and blood lipid level in mice. DESIGN:A completely randomized basic study taking experimental animals as the subjects. SETTINGS:Department of bioengineering,school of life science and technology in a university;Department of endocrinology in a university hospital. PARTICIPANTS:The experiment was completed in the Department of Bioengineering,School of Life Science and Technology in Xi'an Jiaotong University from March to May 2003.ICR mice of clean grade, weighing 20 g to 40 g,were provided by the Shaanxi Academy of Traditional Chinese Medicine[Certification No.08-004]. Juice of Fructus Zipiphi Jujubae:The Chinese date was picked, cleaned,heated and fractured moderately,mixed with water of 10 times and pectinase with the quantity percentage of 0.70% ,soaked at 50 ℃ for 6 hours,then the juice was filtered and condensed into 16% soluble solids,then sterilized for use later.Forty-eight mice (24 male and 24 female) were randomly divided into 4 groups according to body mass with 12 in each group:normal control group(group A), normal date juice group(group B),model control group(group C) and model date juice group(group D). INTERVENTIONS:Mice in group A were fed with basic diet,drank water for 24 hours;Mice in group B were fed with basic diet,drank water and date juice for 12 hours respectively;Mice in group C were fed with high-fat diet,drank water for 24 hours;Mice in group D were fed with high-fat diet,drank water and date juice for 12 hours respectively.Changes of body mass,indexes of thymus gland and spleen were measured after treated with date juice for 30 days.High fat mice models were established,and blood lipid indexes were determined. MAIN OUTCOME MEASURES:Food efficiency of mice,index of thymus gland,spleen index,growth index of mice. RESULTS:The food efficiency and the indexes of thymus gland and spleen in group B were(9.93± 0.473) g/100 g,3.27± 0.35 and 2.93± 0.51 respectively,which were all obviously higher than those in group A[(7.56± 0.382) g/100 g,(3.14± 0.54),(2.87± 0.33)](t=2.55,2.37,2.41,P< 0.05).The body mass was obviously higher in group B [(36.73 ± 4.70) g] than in group A[(34.92 ± 5.12) g] (t=2.32,P< 0.05);while those were very significantly higher in group C and group D [(39.83 ± 6.00), (37.63 ± 2.73) g] than in group A and group B[(34.92 ± 5.12), (36.73 ± 4.70) g](t=4.13,2.48,P< 0.01),and that in the group D[(37.63 ± 2.73) g] was obviously lighter than that in the group C[(39.83 ± 6.00)g](t=2.26,P< 0.05).The serum levels of total cholesterol(TC) in the in group C and group D were significantly higher than those in group A and group B(P< 0.01), while that was significantly lower in group D than in group C(P< 0.05). The serum levels of triglyceride(TG),low-density lipoprotein-cholesterol(LDL-C),arteriosclerosis index(AI),high-density lipoprotein-cholesterol(HDL-C) and HDL-C/TC were significantly higher in group C than in group A(P< 0.01,P< 0.05).TC, HDL-C,AI,HDL-C/TC,TG and LDL-C in group D were lower than those in group C(P< 0.05,P< 0.01). CONCLUSION:Juice of Fructus Zipiphi Jujubae can obviously increase the body mass,promoting food efficiency and indexes of thymus gland and spleen of mice, and has the significant effect on the reinforcement of body function in mice.Juice of Fructus Zipiphi Jujubae can decrease the serum levels of TC,TG and LDL-C in mice with hyperlipidemia,and has the remarkable ameliorating effect on hyperlipidemia of mice induced by high-fat feed.
