ABSTRACT
Objective: To analyze the chemical constituents of Morchella esculenta, and to determine the main activeingredient of it, so as to better control the quality of Morchella esculenta and promote the development and utilization of Morchella. Methods: The compounds were extracted and percolated by ethanol. The samples were separated using silicagel and identified by13C-NMR data. HPLC was used to assay the contents of 4-Hydroxybenzyl alcohol. Results: A totalof 5 compounds were isolated and their structures were identified as 11, 15, 19-trimethyl-5, 9-eicosadienoic acid, cis-13-Docosenoic acid&Erucic acid, 4-Hydroxybenzyl alcohol, Ergosta-5, 7, 22-triene-3β-ol and Mannitol. Conclusion: 4-Hydroxybenzyl alcohol was first isolated from the Morchella esculenta fruiting body, and HPLC method for thedetermination of 4-Hydroxybenzyl alcohol was established. The content of 4-Hydroxybenzyl alcohol were no less than0.40％. The determination method can be used for quality control of Morchella esculenta.
ABSTRACT
The acupuncture direction is closely related with the efficacy of acupuncture analgesia. In this article, the relationship between efficacy of acupuncture analgesia and factors, such as whether the needle towards disease location, whether the needle towards meridian direction, whether the needle following spinal cord direction and whether the needle following muscle direction, were analyzed. The previous clinical and literature research indicated that the needle towards disease location was superior to reverse direction, however, the efficacy of analgesia between needle following and reversing meridian, needle towards and at disease location, needles following and reversing spinal cord direction, needles following and reversing muscle direction was controversial. Therefore, the solutions to these problems will benefit the optimized acupuncture treatment plan for pain disorders.
ABSTRACT
Objective To explore prospectively the relationship between treatment of toxoplasmosis and pregnancy outcome. Methods Detected by ELISA and PCR,59 pregnant women and 91 women at reproductive age with infection were treated by oral spiramycin. Then their Tox-lgM and DNA negative conversing rates,intrauterine transmission rate and incidence of abnormal pregnancy outcome were studied in contrast to those of 60 women in pregnancy and 79 at childbearing age with infection but without management. Results In healing group,the seroconversion rate of Tox-lgM and Tox-DNA from positive to negative were 83.05% (49/59) in pregnant women and 70.33%(64/91) in women at childbearing age,respectively. The rates in control group were 35% (21/60) and 37.97% (30/79). The rates of intrauterine transmission and abnormal pregnancy outcomes of healing group were 8.4% (5/59) and 30% (15/50),respectively. While those of control group were 11.86% (7/59) and 40% (20/50) accordingly (? 2=11.4970,P
