Effect of Lepidium meyenii (Maca) on neurotransmitter level and neuro-endocrine-immune network of deficiency-cold and deficiency-heat syndrome rats / 中国中药杂志

The aim of this paper was to study the effect of Lepidium meyenii(Maca) on cyclic nucleotides, neurotransmitter levels and hypothalamic-pituitary-adrenal axis and immunization of deficiency-cold and deficiency-heat syndrome rats, in order to explore the cold and hot medicinal properties of Maca. SD rats were divided into blank group, deficiency-cold syndrome group, Cinnamomi Cortex of deficiency-cold syndrome(30 g·kg~(-1)) group, high and low-dose Maca groups(2.4, 1.2 g·kg~(-1)), deficiency-heat syndrome group, Phellodendri Chinensis Cortex(PCC) of deficiency-heat syndrome(5 g·kg~(-1)), and high and low-dose Maca groups(2.4, 1.2 g·kg~(-1)). The rats were treated with intramuscular injection of hydrocortisone(20 mg·kg~(-1)) or dexamethasone sodium phosphate(0.35 mg·kg~(-1)) for 21 days to set up the deficiency-cold and deficiency-heat model. The levels of cAMP, cGMP, NE, DA, 5-HT, CRH, ACTH, CORT and IgM, IgG, C3, C4 were detected by radio immunoassay. Both the high-dose Maca group and the low-dose Maca group can significantly improve the overall state and body weight of rats with deficiency-cold syndrome(P<0.01, P<0.05), significantly increasing cAMP, cAMP/cGMP, NE, DA, ACTH(P<0.01, P<0.001), and significantly decreasing 5-HT(P<0.01, P<0.001). However, high-dose and low-dose Maca groups could not improve the deficiency-heat syndrome, and the levels of cAMP, cGMP, cAMP/cGMP, NE, DA, 5-HT and ACTH were not statistically significant. Maca had a significant regulatory effect on CORT, IgM, IgG and C3 content of rats with deficiency-cold and deficiency-heat syndrome(P<0.01, P<0.05, P<0.001). Maca showed the same effect with Cinnamomi Cortex in adjusting the levels of deficiency-cold rats, but in opposition to Phellodendri Chinese Cortex. This paper confirmed that Maca was slightly warm based on its effect on cyclic nucleotide levels and neuro-endocrine-immune networks by the pharmacological experimental method.

Effect of Açaí oil, alcohol extract and water extract on temperature tendency and metabolic level of mice with deficiency-feat and deficiency-cold / 中国中药杂志

To investigate the effect of resolution components, such as Açaí oil, alcohol extract and water extract, on the temperature tendency animal behavior and intrinsic biochemical indexes, such ascyclic nucleotides and metabolic level, in mice with deficiency-heat and deficiency-cold syndrome, in order to study the characteristics of the cold and heat properties of each resolution component of Açaí and the material basis of cooling. KM mice were randomly divided into 12 groups, namely blank group, deficiency-heat model group, deficiency-heat+Açaí group, deficiency-heat+Açaí oil group, deficiency-heat+Açaí alcohol extract group, deficiency-heat+Açaí water extract group, deficiency-cold model group, deficiency-cold+Cinnamomi Cortex group, deficiency-cold+Açaí group, deficiency-cold+Açaí oil group, deficiency-cold+Açaí alcohol extract group, deficiency-cold+Açaí water extract group. The mice in deficiency-heat group were given thyroid tablet solution(160 mg·kg~(-1)), the mice in deficiency-cold group were given hydrocortisone solution(25 mg·kg~(-1)) through gastric perfusion every afternoon for 14 days, and each administration group was given the corresponding drug. The temperature tendency, cyclic nucleotides and metabolic level of animals were measured after the experiment. The Açaí alcohol extract was consistent with the Açaí powder, with a regulatory effect on the deficiency-heat model mice; Açaí oil and its water extract were consistent with Cinnamomi Cortex, with a regulatory effect on the deficiency-cold model mice. In this study, based on the parable theory of traditional Chinese medicine's properties and tastes, property of alcohol extract of Açaí was cool, while the property of oil and water extract were warm, the alcohol extract of Açaí was the material basis of Açaí cold medicine by the methods of homogeneous comparison and heterogeneous disproval.

Analysis of bioactive components of novel jujube beverage from Laoling Zizyphus Jujuba cv.Jinsixiaozao / 中国生化药物杂志

Objective To detect the main nutritional components of novel jujube beverage from Laoling Zizyphus Jujuba cv.Jinsixiaozao.Methods Free monosaccharides in novel jujube juice were determined by the HPLC-RID method while water-soluble polysaccharides were analyzed by UV spectrophotometric method with the phenol-sulfuric acid derivatization.Amino acid and mineral contents were obtained by the automatic amino acid analyzer and atomic absorption photometric methods, respectively.The quantification of total phenolic and flavonoids was accomplished by the UV spectrophotometric method after the respective complexation of the Folin-Ciocalteu reagent and aluminum nitrate.The contents of rutin and cyclic nucleotides were determined by the HPLC-UV method.Results The average contents of sucrose, glucose, fructose and polysaccharides in novel jujube juice were 3.85, 32.5,27.3 and 3.6 mg/mL, respectively.The total amino acid average content was 269.7 μg/mL.The mineral average contents of Ca, Fe, Mg, Zn, Mn, Cr, and Cu were 35.1,0.85, 55.8, 0.85, 0.44, 0.41, 0.21μg/mL, respectively.The novel jujube juice contained average 1.34μg/mL rutin equivalents of total phenolics and average 157.3 μg/mL gallic acid equivalents of total flavonoids.Finally, the average amounts of rutin, cAMP and cGMP were 7.15, 19.17 , and 8.11 μg/mL, respectively.Conclusion The newly developed jujube juice is worthwhile further marketing development attributed to its rich nutritional components and healthy values .

Effects of Yougui Wan on Thyroid Hormone and Cyclic Nucleotides Levels in Rats with Spleen-kidney Deficiency Syndrome / 广州中医药大学学报

Objective The changes of thyroid hormone and cyclic nucleotides levels in rats with spleen-kidney deficiency syndrome were observed to evaluate the preventive and therapeutic effect of Yougui Wan(YW) for spleen-kidney deficiency syndrome,and to explore the relationship between the spleen and the kidney at microscopic level.Methods Male SD rats were randomly divided into normal control group,model group,and YW group.Rat models of spleen-kidney deficiency syndrome were established by gavage firstly with rhubarb(4g for each rat) decoction and then with hydrocortisone(25 mg?kg-1?d-1,im).The model group and YW group were treated with distilled water and YW(5.8 g?kg-1?d-1) respectively.The general status of rats was observed,and the plasma cyclic adenosine monophosphate(cAMP) and cyclic guanosine monophosphate(cGMP) levels as well as serum thyroid hormones(T3,T4 and rT3) and thyroid-stimulating hormone(TSH) contents were determined in all rats by radioimmunoassay(RIA).Results Compared with the normal control group,the serum contents of T3,T4,rT3 were decreased significantly(P

It was found that gypsum could inhibit the rise of body temperature caused by LP injection, (△T of gypsum +LP group is 0.40?0.08℃, TRI_3 2.55; LP group 0.91?0.06℃, TRI_3 4.99 P

Balneotherapy in Diabetics / 日本温泉気候物理医学会雑誌

Usefulness of balneotherapy in diabetics were discussed. Plasma glucose levels in diabetics treated with insulin decreased significantly after thirty minutes exercise under 38°C hot springs pool. There were positive relationships on plasma glucose levels between before and after exercise in hot springs. Lipids metabolism were improved during three months' balneotherapy. The ratio of VLDL·LDL-cholesterol/HDL-cholesterol decreased. Basal levels of plasma cyclic AMP decreased slightly and plasma cyclic GMP significantly increased. Intrathecal injection of vitamin B₁₂ (mecobalamin, 2500μg) was apparently effective to reduce the pain on under limb in patients with diabetic peripheral neuropathy whose subjective symptom could not improved by any medications. The effect of mecobalamin was increased by bathing in hot springs. Usually, balneotherapeutic hospitals have facilities of rehabilitation system in Japan.<br>In conclusion, the balneotherapy by adding physical treatment is very benefit to normalize carbohydrate and lipid metabolism. Tranquilizing function of hot springs are effective on psychological disturbance, diabetic autonomic and peripheral neuropathy.
