Anxiolytic and antidepressant effects of agarwood inhalation and its mechanism / 中国中药杂志

This study used m-chloropheniperazine(MCPP) and chronic unforeseeable mild stress(CUMS) to induce the rat models of anxiety and depression, respectively. The behaviors of rats were observed by the open field test(OFT), light-dark exploration test(LDE), tail suspension test(TST), and forced swimming test(FST), and the antidepressant and anxiolytic effects of agarwood essential oil(AEO), agarwood fragrant powder(AFP), and agarwood line incense(ALI) were explored. The enzyme-linked immunosorbent assay(ELISA) was used to determine the levels of 5-hydroxytryptamine(5-HT), glutamic acid(Glu), and γ-aminobutyric acid(GABA_A) in the hippocampal area. The Western blot assay was used to determine the protein expression levels of glutamate receptor 1(GluR1) and vesicular glutamate transporter type 1(VGluT1), exploring the anxiolytic and antidepressant mechanism of agarwood inhalation. The results showed that compared with the anxiety model group, the AEO, AFP, and ALI groups decreased the total distance(P<0.05), decreased the velocity of movements(P<0.05), prolonged the immobile time(P<0.05), and reduced the distance and velocity of the rat model of anxiety in the dark box(P<0.05). Compared with the depression model group, the AEO, AFP, and ALI groups increased the total distance and average velocity(P<0.05), reduced the immobile time(P<0.05), and reduced the forced swimming and tail suspension time(P<0.05). In terms of transmitter regulation, the AEO, AFP, and ALI groups decreased the level of Glu in the rat model of anxiety(P<0.05) and increased the levels of GABA_A and 5-HT(P<0.05), while the AEO, AFP, and ALI groups all increased the level of 5-HT in the rat model of depression(P<0.05) and decreased the levels of GABA_A and Glu(P<0.05). At the same time, the AEO, AFP, and ALI groups all increased the protein expression levels of GluR1 and VGluT1 in the hippocampus of the rat models of anxiety and depression(P<0.05). In conclusion, AEO, AFP, and ALI exert anxiolytic and antidepressant effects, and the mechanism might be related to the regulation of the neurotransmitter and the protein expression of GluR1 and VGluT1 in the hippocampus.

Herbal Textual Research on Traditional Chinese Medicines of Doukou in Famous Classical Formulas / 中国实验方剂学杂志

Chinese medicines of Doukou includes Amomi Fructus Rotundus， Alpiniae Katsumadai Semen， Galangae Fructus and Myristicae Semen. They have a long medicinal history and are also commonly used in cooking and seasoning. Due to the similar names and limited to the traffic conditions in ancient times， the records of Doukou in ancient literature are often confused with many plants in the same family， and there are still many kinds of confused products. In order to promote the development of famous classical formulas containing the medicinal materials， the ancient literature of Doukou in the past dynasties was comprehensively combed from the aspects of name， origin， genuine area， medicinal parts， harvesting and processing and processing methods. It has been found that the basic original plants of Amomi Fructus Rotundus are Amomum kravanh and A. compactum， the original plant of Alpiniae Katsumadai Semen is Alpinia katsumadai and it often confused with Tsaoko Fructus. The main source of Galangae Fructus recorded in the ancient materia medica is the fruit of A. officinarum， while the 2020 edition of Chinese Pharmacopoeia stipulates that the original plant is A. galanga. Myristica fragrans is the original plant of Myristicae Semen. It was found that except M. fragrans， the other three kinds of medicinal origin of Doukou had changed， there are many other plants confused with each other. The four kinds of Doukou are produced in Southeast China and Southeast Asia， and most of Amomi Fructus Rotundus and Myristicae Semen are imported. The Chinese medicines of Doukou have clear medicinal parts and simple processing methods， the main methods in the past dynasties are cleaning， stir frying and simmering， and the processed products are selected according to the needs of different diseases. It is suggested to use the dry mature seeds of A. katsumadai in Houpo Wenzhongtang， which is from Guangxi， Guangdong， Hainan， Fujian and Yunnan and so on， among which Wanning in Hainan province is genuine producing area. The fruits should be harvested in summer and autumn， and dried to 90% dry in the sun， or slightly scalded with water and dried to half dry in the sun， and removed the peel， taken out the seed group， dried in the sun and then be used as medicine.

Herbal Textual Research on Arecae Semen in Famous Classical Formulas / 中国实验方剂学杂志

In this paper， the name， origin， changes of producing area， medicinal parts， quality evaluation and processing methods of Arecae Semen in the famous classical formulas by consulting related herbal medicines， medical books and prescription books. The results showed that the names of Arecae Semen in the past dynasties were mostly derived from its shape， efficacy and producing area. The main base of the past generations was Areca catechu， the medicinal parts were its seeds （Arecae Semen） and pericarps （Arecae Pericarpium）. Arecae Semen is produced in Hainan province of China. Since modern times， it has been concluded that the best quality is large， heavy， firm， and unbreakable. The main processing methods of Arecae Semen in the past dynasties were netting， cutting and frying. Therefore， it is suggested that Arecae Semen should be used in Dayuanyin. If the processing requirements of Arecae Semen are not clearly indicated， it can be processed according to raw products in the 2020 edition of Chinese Pharmacopoeia.

Anti-asthmatic effect of agarwood alcohol extract in mice and its mechanism / 中国中药杂志

As recorded, agarwood has the function of improving qi reception and relieving asthma, but the underlying mechanism is unclear and rarely reported. Therefore, this study explored the anti-asthmatic effect of the alcohol extract of agarwood produced by the whole-tree agarwood-inducing technique(Agar-Wit) in the asthma mouse model induced by intraperitoneal injection of ovalbumin(OVA) + Al(OH)_3 combined with intranasal administration of OVA and the mechanism, and compared the anti-asthmatic effects of agarwood induced with different methods. Firstly, the anti-inflammatory and anti-asthmatic effects of Agar-Wit agarwood in mice were evaluated based on the asthma frequency, lung tissue injury, and peripheral inflammatory white blood cell(WBC) count and eosinophil count. Then, the levels of interleukin-1β(IL-1β), IL-17, and IL-10 in serum of mice were detected by enzyme-linked immunoassay(ELISA) and the expression of inflammation-and apoptosis-related genes in tissues was measured by reverse transcription polyme-rase chain reaction(RT-PCR) so as to preliminarily explore the anti-asthmatic mechanism. RESULTS:: showed that the alcohol extract of Agar-Wit agarwood significantly reduced asthma frequency, relieved pathological injury, improved peripheral WBC count and eosinophil count, decreased the levels of inflammatory cytokines IL-1β and IL-17, elevated the level of anti-inflammatory cytokine IL-10, and down-regulated the mRNA expression of IL-1 R, tumor necrosis factor receptor R(TNFR), nuclear transcription factor-kappa B(NF-κB), Bax, and caspase 3, but had no significant influence on the expression of high-mobility group box 1(HMGB1) protein, caspase 8, and Bcl-2. The effect of Agar-Wit agarwood alcohol extract was better than that of wild agarwood alcohol extract and alcohol extract of agarwood induced with the burning-chisel-drilling method at the same dose. In conclusion, Agar-Wit agarwood can significantly alleviate inflammation and asthma, which is related to its anti-inflammation and anti-apoptosis activity.

A Review of Quality Assessment and Grading for Agarwood / 中草药·英文版

Agarwood is an important non-timber forest product widely used in religious and cultural activities as perfume and fragrance and as traditional medicine in Asia. The high value of agarwood and the inflated consuming market have led to constant rising of the prices. In general, the price of the agarwood is determined according to its quality, which can be divided into different grades. But up to now, there is not any standard quality grading system which could be used overwhelmingly throughout the agarwood producing, commerce and consumption. Therefore, we reviewed agarwood in diversified grading indexes, systems and methods.

Effect of agarwood extracts produced by the whole-tree agarwood-inducing technique on gastrointestinal motility and gastric ulcer / 国际药学研究杂志

Objective To evaluate the gastrointestinal regulative effect of agarwood extracts produced by the whole-tree agar- wood-inducing technique (Agar-Wit agarwood) to make scientific basis for the Agar-Wit agarwood exploration and usage in clinic. Methods Intestinal propelling effect assay marked by carbon powder, and gastric empting effect assay marked by methyl orange were used to evaluate the gastrointestinal effects of Agar-Wit agarwood on mice by single or constant repeated intragastric (ig) administration of water extract and ethanol extract, and then the index of intestinal peristaltic rate and methyl orange relative residual rate were calculated. Gastrtic ulcer model was established under water stress to appraise their protective function on rat stomach and to obtain the gastric ulcer index and inhibitory rate. Results The Agar-Wit agarwood ethanol extract significantly improved intestinal peristalsis and gastric empting function by single or constant repeated ig administration at the dose of 150 mg/kg. The ethanol extract of commercial agarwood also had the similar effect at the dose of 450 mg/kg. But the water extract did not have significant effect. The gas ulcer assay results showed that the ethanol extract significantly inhibited gastric ulcer happening by single ig administration. Additionally,constant repeated ig administration of ethanol extract showed the consistent results and the gastric ulcer inhibitory rate was (73.1±5.6)% at the dose of 300 mg/kg. Conclusion The Agar-Wit agarwood ethanol extracts have significant intestinal peristaltic effect,gastric empting effect and gastric ulcer inhibitory function.

Amplification effect of acupoint from feeling of acupoint and transmitting of meridian / 中国针灸

Through arrangement and analysis of domestic and overseas literature about effect of acupoint, it is found that acupoint is an amplifier of acupuncture effect, which could present feature of weak-stimulation and strong-response for acupuncture stimulation. It is also thought that factors of the amplification effect are complicated, it is closely related to the local specificity of acupoint (including more nerves, more blood vessels, more mast cells, more Ca2+ and more energy metabolism) and circulation route of meridians, indicating the amplification effect works through local feeling (local specificity of acupoint) into the distal end (circulation and distribution route of meridian system.

Historical records and modern studies on agarwood production method and overall agarwood production method / 中国中药杂志

Agarwood is a precious traditional Chinese medicine with the efficacy of promoting qi circulation and relieving pain, warming middle-jiao, controlling nausea and vomiting, governing inspiration and relieving asthma, therefore it is widely applied in the clinic. Meanwhile, agarwood is also a precious spice. Aquilaria sinensis is the only source of agarwood production in China. Under natural conditions, a healthy A. sinensis tree produces no agarwood. Only if being wounded or infected with fungus can it synthetize and accumulate agarwood. It takes a decade or even several decades to produce agarwood, thus natural agarwood can not meet market demands. The essay summarizes historical records of agarwood production method and modern agarwood production method, in order to provide basis and reference for large-scale production of agarwood.
