OBJECTIVE To separate and identify the chemical constituents of the aerial part of Gaultheria leucocarpa var. yunnanensis. METHOD The compounds were extracted with solvents, isolated by column chromatography and identified by spectral analysis. RESULT Four compounds were identified as n-dotriacontane and its homologous compound(1), ursolic acid(2),(More)
To evaluate the roles of spinal neurokinin receptors in the development of persistent nociception and hyperalgesia to thermal and mechanical stimuli induced by subcutaneous (s.c.) bee venom injection, effects of intrathecal (i.t.) pre- or post-treatment with a non-selective antagonist of (NK1/2) receptors, [D-Arg1,D-Trp7,9,Leu11] substance P (spantide), and(More)
SETTING The Fujian District in China has a high migrant worker population. Although tuberculosis (TB) among migrants is a serious threat to public health in Fujian, little is known about the molecular characteristics of TB isolates in this population. OBJECTIVE To investigate the genetic profile of TB among the migrant population in Fujian. RESULTS Our(More)
OBJECTIVE To further develop Gaultheria leucocarpa var. yunnanensis, anti-bacteria constituents in it were screened. METHOD The constituents were extracted by chromatographic process. The anti-bacteria test was made with regulatory method of analysis. RESULT AND CONCLUSION Anti-bacteria test with extracts of water, acetic ester and n-butanol showed that(More)
AIM To study the effect of quaternary ammonium salt derivative of haloperidol (F3) on intracellular calcium (Ca2+) dynamic change in vascular smooth muscle cells (VSMC). METHODS Using laser confocal scanning microscopy (LCSM), to observe the effect of F3 (0.01 - 10 micromol/L) on increase of intracellular Ca2+ fluorescent intensity induced by KCl (30(More)
OBJECTIVE To study the resources of G. leucocarpa var. yunnanensis for further development of this drug. METHOD Field investigating, consulting with relevant experts and looking into available specimens. RESULTS AND CONCLUSION G. leucocarpa var. yunnanensis is widely distributed in the southern regions of the Yangtze River. The field investigation(More)
OBJECTIVE To study the saponin from Albizia julibrissin. METHODS A saponin was separated by using chromatography and its structure was elucidated on the basis of spectral data. RESULTS A saponin was obtained and it's structure was identified as 3-O-[beta-D-xylopyranosyl-(1-->2)-alpha-L-arabinopyranosyl-(1-->6)-beta-(More)
Intracerebral-ventricular (icv) injection of 4-aminopyridine (4-AP) 8 micrograms to rabbits generated convulsions and epileptic discharges in electrocorticogram (ECoG). With 40 rabbits, the occurrence of convulsion at this dose level was 100%. The results from five rabbits showed that seizures may break out repeatedly at intervals of 1-5 min and such state(More)
Thirty-nine cases of chyluria and scrotal lymphangial fistula treated by microsurgery between April 1980 and October 1989 are presented. Several different methods were used. In males a lymphatico-venous anastomosis of the spermatic cord was performed and in females the lower inguinal lymph nodes were anastomosed to the branches of the greater saphenous(More)
