China Journal of Chinese Materia Medica 2014;39(8):1468-1472
OBJECTIVETo investigate the effect of tanshinone II(A) on the expression of different components in the renin-angiotensin system of left ventricles of renal hypertensive rats.
METHODThe renal hypertension model was established in rats by the two-kidney-one-clip (2K1C) method. In the experiment, all of the rats were randomly divided into four groups (n = 15 per group) before the operation: the sham-operated (Sham) group, the hypertensive model (Model) group, the low-dose tanshinone II(A) group and the high-dose tanshinone II(A) group. At 5 week after the renal artery narrowing, the third and fourth groups were administered with 35 mg kg(-1) x d(-1) and 70 mg x kg(-1) x d(-1) of tanshinone II(A), respectively. The blood pressure in rats was determined by the standard tail-cuff method in each week after the operation. After the drug treatment for 8 weeks, all the rats were put to death, and their left ventricles were separated to determine the ratio of left ventricle weight to body weight (LVW/BW), the myocardial collagen content, and the expressions of different components in myocardial RAS, including angiotensin converting enzyme (ACE), angiotensin converting enzyme 2 (ACE2), angiotensin 1-type receptor (AT1R), Mas receptor mRNA expression and angiotensin II (Ang II) and angiotensin (1-7) [Ang (1-7)] content.
RESULTCompared with the sham group, the hypertensive model group exhibited a markable increase in the content of Ang II and Ang (1-7) and the mRNA expressions of ACE, ACE2, AT1R and Mas (P < 0.01). However, the treatment with tanshinone II(A) showed the does dependence, inhibited left ventricle hypertrophy, decreased myocardial Ang II content and the mRNA expression of ACE and AT, R in renal hypertensive rats (P < 0. 01) , further increased the myocardial Ang (1-7) content and the mRNA expression of ACE2 and Mas (P < 0.01) , but without any change in the blood pressure of hypertensive rats.
CONCLUSIONThe treatment with tanshinone II(A) could inhibit left ventricle hypertrophy of renal hypertensive rats. Its mechanism may be partially related to the expression of different components in the renin-angiotensin system for regulating myocardial tissues.

4.RANDOM AMPLIFIED POLYMORPHIC DNA(RAPD)REVEALED THE HETEROKARYON OF AGARICUS ARVENSIS PRODUCED BY MATING REACTIONS
Microbiology 1992;0(05):-
s: The horse mushroom (Agaricus arvensis Schaeff ex Fr.) is one of most excellent edible mushroom,and was cultivated in world at resent year.But up to now,the breeding systems and life-cycle of horse mushroom has been poorly know.In this study,the random amplified polymorphic DNA was employed to analyse the mating reaction between self-fertile homokaryonic isolates by paired.The results demonstrated: (1) the mating reaction happened and the heterokaryonic offspring formed when the intercompatible self-fertile homokaryonic isolates were paired;(2) perhaps the horse mushroom is possessed of double breeding systems-homothallism and heterothallism;(3) RAPD is very effective method for verifying artificially synthesized heterokaryons and monitoring the transmission of genetic loci in mating of fungi.

9. The in vitro antioxidative activity of the compound astragalus, glycyrrhiza and schisandra extract and the determination of bioactive component contents
Journal of International Pharmaceutical Research 2019;46(6):479-484
Objective: To investigate the antioxidative activity of compound Astragalus, Glycyrrhiza and Schisandra extract(CAGSE)and determine the content of related bioactive components. Methods: The CAGSE was prepared by the extraction of the Astragalus, Glycyrrhiza and Schisandra raw materials with ethanol. Experimental groups for the antioxidative activity test were set as the control group, vitamin C group(VC group, positive control)and the CAGSE 0.1, 0.2 and 0.5 g/ml groups. The antioxidant effect of CAGSE was evaluated by the assay for the inhibition of linoleic acid autooxidation, the reducing power assay(the method of Oyaizu)and the assay for the 1, 1-diphenyl-2-picryl hydrazine(DPPH)free radical scavenging activity. The content of schisandrae b was determined by the HPLC method, the total phenol content(TPC)was determined by the folin-ciocalteu method using gallic acid as the standard, and the total flavonoid content(TFC)was determined by the ultraviolet spectrophotometry with rutin as the standard. Results :Com- pared with the VC group, the inhibition rate on the linoleic acid autooxidation was significantly increased in all of the CAGSE 0.1, 0.2, and 0.5 g/ml groups(P<0.05)and the reducing power was also significantly enhanced in all the CAGSE groups(P<0.05). The DPPH free radical scavenging activity was significantly higher in the CAGSE 0.1, 0.2 and 0.5 g/ml groups than in the VC group(P<0.05). The TFC in the 0.1 g/ml concentration CAGSE was 54.39 mg/g, the TPC was 38.65 mg/g, and the content of schisandrin b was 0.76 mg/g. Conclusions: The CAGSE showed a significant antioxidant activity, and the content of total flavonoids, total phenolics and schisandrin b were 54.39, 38.65 and 0.76 mg/g, respectively.

Objective: To observe the clinical efficacy of heat-sensitive moxibustion for adjuvant treatment of depression in Parkinson disease and explore its mechanism. Methods: A total of 80 patients with Parkinson disease coupled with depression were randomized into an observation group and a control group, with 40 cases in each group. The control group was treated with levodopa and benserazide hydrochloride tablets and paroxetine tablets, while the observation group was treated with heat-sensitive moxibustion on the basis of the medications in the control group. The treatment course was 2 months. The Hamilton depression scale-17 (HAMD-17), unified Parkinson's disease rating scale (UPDRS) and Parkinson's disease quality of life questionnaire-39 (PDQ-39) were scored before and after the treatment, and the efficacy was evaluated after treatment. Levels of patients' serum dopamine (DA), 5-hydroxytryptamine (5-HT), tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) were detected before and after the treatment. Results: After treatment, the total effective rate of the observation group was higher than that of the control group (P<0.05). The HAMD-17 scores in the two groups decreased significantly after treatment (both P<0.05), and the score in the observation group was obviously lower than that in the control group (P<0.05). The component scores and total scores of UPDRS in both groups decreased significantly (all P<0.05), and the scores in the observation group were lower than those in the control group (all P<0.05). The score of PDQ-39 in the observation group decreased significantly (P<0.05), and was lower than that in the control group (P<0.05). After treatment, the serum DA and 5-HT levels in the observation group increased significantly (both P<0.05) and the TNF-α and IL-6 levels decreased significantly (both P<0.05), which were statistically different from those in the control group (all P<0.05). Conclusion: Heat-sensitive moxibustion has certain auxiliary effect in treating depression in Parkinson disease, significantly improving clinical symptoms and the quality of life, which may be related to the up-regulation of DA and 5-HT levels and down-regulation of TNF-α and IL-6 levels.
