Impact of Chisan (ADAPT-232) on the quality-of-life and its efficacy as an adjuvant in the treatment of acute non-specific pneumonia

A double-blind, placebo-controlled, randomized (simple randomisation), pilot (phase III) study of Chisan^® (ADAPT-232; a standardised fixed combination of extracts of Rhodiola rosea L., Schisandra chinensis Turcz. Baill., and Eleutherococcus senticosus Maxim) was carried out on two parallel groups of patients suffering from acute non-specific pneumonia. Sixty patients (males and females; 18–65 years old) received a standard treatment with cephazoline, bromhexine, and theophylline: in addition, one group of 30 patients was given Chisan mixture, whilst the second group of 30 patients received a placebo, each medication being taken twice daily from the beginning of the study for 10–15 days. The primary outcome measurements were the duration of antibiotic therapy associated with the clinical manifestations of the acute phase of the disease, together with an evaluation of mental performance in a psychometric test and the self-evaluation of quality-of-life (QOL) (WHOQOL-Bref questionnaires) before treatment and on the first and fifth days after clinical convalescence. The mean duration of treatment with antibiotics required to bring about recovery from the acute phase of the disease was 2 days shorter in patients treated with Chisan compared with those in the placebo group. With respect to all QOL domains (physical, psychological, social and ecological), patients in the Chisan group scored higher at the beginning of the rehabilitation period, and significantly higher on the fifth day after clinical convalescence, than patients in the control group. Clearly, adjuvant therapy with ADAPT-232 has a positive effect on the recovery of patients by decreasing the duration of the acute phase of the illness, by increasing mental performance of patients in the rehabilitation period, and by improving their QOL. Both the clinical and laboratory results of the present study suggest that Chisan (ADAPT-232) can be recommended in the standard treatment of patients with acute non-specific pneumonia as an adjuvant to increase the QOL and to expedite the recovery of patients.

天然次生林三种不同生境刺五加丁香苷和总黄酮含量的研究

采用高效液相和分光光度的方法对天然次生林林内、林隙和林缘三种不同生境下刺五加(Acanthopanax senticosus)主要次生代谢产物丁香苷和总黄酮的含量差异进行了研究。结果表明:不同生境条件下,刺五加不同部位丁香苷的含量不同。生境的变化对枝中丁香苷的含量影响最大,林内生境枝中丁香苷的含量最低,林隙生境较高,林缘生境最高。而茎基部丁香苷的含量规律为林内生境最高,林隙生境次之,林缘生境最低。三种不同生境中根和根茎丁香苷含量的变化没有明显的规律性。刺五加全株均含有黄酮类物质,其中叶和花中黄酮的含量较高。其总黄酮含量受环境的影响较大,在林内生境,刺五加叶、花和果中总黄酮的含量最低,林隙生境有所提高,而林缘生境中含量最高。叶片总黄酮含量与叶面积指数呈负相关,叶面积指数越大,叶片中总黄酮的含量越低。对于刺五加的枝、茎干、根和根茎而言, 1~3年枝总黄酮在各个生境之间没有显著的差异;而茎干中总黄酮的含量表现为林内生境显著的高于林隙生境和林缘生境,后两者没有明显的差异;与茎干不同,林内生境根和根茎中总黄酮的含量最低,林隙和林缘的较高。

Quantitative analysis of endangered Acanthopanax senticosus communities in Dongling Mountain of Beijing

Based on the survey of community plots, a quantitative analysis of endangered Acanthopanax senticosus communities in Dongling Mountain was performed with two way indicator species analysis (TWINSPAN), detrended correspondence analysis (DCA) and canonical correspondence analysis (CCA). The communities of A. senticosus were classified into 9 types by TWINSPAN and the results were validated by DCA. On the DCA graph, the first axis reflected the gradient of altitude and the second axis reflected the aspect and slope. Most of A. senticosus were distributed in the thick forests at a high altitude with little light. With the exception of being a dominant species of shrub layers in a few communities, A. senticosus has a relatively scarce distribution. In accordance with DCA, the results of CCA also show the trend that the distribution of A. senticosus communities varied along with the gradient change of environmental factors. Altitude and light are the main factors affecting A. senticosus growth. __________ Translated from Chinese Journal of Ecology, 2007, 26(3): 314–318 [译自: 生态学杂志]     

Quality control of roots of Eleutherococcus senticosus by HPLC

An HPLC method based on several known methods for the determination of eleutherosides B and E was developed, optimised and validated in terms of linearity, precision (repeatability and intermediate precision on different days and at different concentration levels) and accuracy (recovery). The extraction procedure, the extraction solvent and the extraction yield were evaluated and optimised. A reversed-phase RP-18 column gradient eluted with a two-phase system consisting of phosphoric acid:water (0.5:99.5) and acetonitrile was used to evaluate the samples; detection was at 220 nm. Although eleutherosides B and E are commercially available, they are very costly, and therefore ferulic acid was chosen as external standard. The correction factors for the response of ferulic acid against both eleutherosides were determined and validated. This method, accepted by the European Pharmacopoeia Commission, will be included in the monograph on Eleutherococcus senticosus roots to assay the content of eleutherosides B and E.     

Nutrition of Threonine

Among the threonine dehydratase activities in liver of rat fed on basal diet (B-group), lysine added diet (L-group) and threonine added diet (T-group), a following relationship was found: A_B?A_LT, where A_B, A_L and A_T were the activities of B-, L-and T-group, respectively. The types of the activity increase in L- or T-group were investigated by examining the possibility of the cause—the existence of activators in L- or T-group (I), the existence of inhibitors in B-group (II), the activation of the latent enzyme in L- or T-group (III), and the induction of the dehydratase by biosynthesis in L- or T-group (IV). Addition of various amounts of liver homogenate of L- or T-group to a given amount of that of B-group gave a result as would be obtained in cases where neither activators nor inhibitors existed in the liver (I and II). No correlationship was found between the activity and the preincubation time, which denied the presence of the latent enzyme which would easily change into the active form by preincubation (III). Actinomycin D administered to rats inhibited the increase of the dehydratase activity of L- or T-group by about 50% (IV). On the other hand, preliminary experiments using hypophysectomized or adrenal-ectomizecl rats showed the results of A_в?A_L?A_т. Both results may suggest the possibility that the increase of the dehydratase activity is ascribed to the induction of this enzyme through biosynthesis, and perhaps through endocrine systems.

Effects of Acanthopanax senticosus supplementation on innate immunity and changes of related immune factors in healthy mice

Modern scientific research has shown that Acanthopanax senticosus (AS) can regulate the innate immunity of healthy animals, thus affecting the health of animals. However, there are few systematic reports on the changes of innate immune indices of healthy animals after consuming AS. The purpose of this project was to study the effect on healthy mice’s innate immunity and changes of related immune factors induced by feeding AS root powder supplementation. The results showed that the killing rate of natural cells increased in a dose-dependent manner in a certain time period. Compared to the control group, the treatment groups (T1, T2 and T3) improved significantly in the innate immune index (lysozyme, β-defensin-2 and duodenal secretory IgA (SIgA) to varying degrees) and induced corresponding changes of immune factors at certain time periods. The correlation between SIgA and IFN-γ in mouse serum was enhanced, and the higher the concentration of AS in the diet, the stronger the correlation was. However, there was no significant difference in growth performance among groups. It is proved that AS supplementation can enhance innate immunity and change several relevant immune factors and cells of healthy mice without affecting growth performance.
