| 1 | Effect of moxa smoke produced during combustion of Aiye(Folium Artemisiae Argyi) on behavioral changes in mice inhaling the smoke显示文摘OBJECTIVE: To evaluate the effects that inhalation of the combustion products of the traditional Chinese herb Aiye(Folium Artemisiae Argyi) has on the central nervous system.METHODS: Forty Kunming mice(half male) were randomly assigned(n = 10/group) to a control group(C) or one of three moxa smoke concentration groups(% opacity): low(L1; 0.4%), medium(M1; 2%), and high(H1; 15%). Mice in the latter three groups were exposed to moxa smoke in a dynamic gas exposure cabinet for 20 min per day for7 days. Mice in control group were placed in the same cabinet without any intervention. For the sleep experiments, another 50 mice were divided into five groups of 10 mice each: a saline-injected control group, L1 + pentobarbital sodium(PS)-injected group, M1+PS group, H1(15%)+PS group,and a positive control group(10 mg/kg, chlorpromazine, p.o.). The weight, general activities, locomotor activities, rotarod performance, sleep duration,and sleeping rate induced by a subthreshold dose of pentobarbital sodium were recorded in the mice,and the composition of moxa smoke was analyzed using headspace gas chromatography(GC-HS).RESULTS: A low concentration of smoke significantly decreased the frequency of locomotor activities and the time for which the mice remaining on the rotarod; however, a high smoke concentration significantly prolonged the pentobarbital-induced sleeping time and sleeping rate.CONCLUSION: The concentration-dependent relaxing effects of moxa smoke on the Central Nervous System(CNS) were confirmed. Moreover, GC-HS analysis showed that the component present in the highest concentration in moxa smoke was eucalyp-tol, an essential oil well recognized for its soothing effects on the CNS. This may therefore be accountable for the sedative effects of moxa smoke. | Yang Jia Zheng Xiaojun Jin Ran Han Li Ha Lue Li Jun Wang Lei Liu Ping Chu Zhusheng Huang Chang Chang Hongsheng Lao Lixing Zhao Baixiao | 2016 | Journal of Traditional Chinese Medicine2016，36，6： | 8 |
| 3 | Preliminarily study of Saturn’s upper atmosphere density by observing Cassini plunging via China’s deep space station显示文摘When the Cassini spacecraft finally plunged into the Saturnian atmosphere on 2017 September15,China’s deep space telescope pointed to Saturn to observe Cassini and study the Saturnian upper neutral atmosphere.In this first Chinese Saturnian radio science experiment,X band Doppler velocity radio science data between the deep space telescope and the Cassini spacecraft were obtained.After removing Saturnian and solar gravity effects,Earth rotation effect,the remaining Saturnian atmosphere drag information was retrieved in the Cassini final plunge progress.Saturn’s upper neutral atmosphere mass density profile is approximately estimated based on atmosphere mass density derived principally by real orbit measurement data.Saturn’s upper neutral atmosphere mass density from 76000 km to 1400 km is estimated from the orbit measurement data,the mass density results are about from 1.4×10^-15 kg cm^-3 to 2.5×10^-14 kg cm^-3. | Lue Chen Jin-Song Ping Xiang Liu Na Wang Jian-Feng Cao Guang-Ming Chen Ming-Yuan Wang Wen-Xiao Li Jian-Hui Zhang Yong-Qiang Chen Shi-Lei Yue Song-Tao Han Jing Sun | 2020 | Research in Astronomy and Astrophysics2020，20，7： | 1 |
