Although proprietary medicines and decoction of processed aconite roots are the most widely used, tincture accounts for the great majority of aconite poisoning cases in China, indicating that it is much more toxic than other formulations. Aconite tincture is often self-prepared at home and raw aconite plants or roots are often used. Even if processed aconite roots were used to make the tincture, the amount of Aconitum alkaloids is highly variable, depending on the adequacy of processing and quality control. Aconitum alkaloids dissolve efficiently in alcohol. For these reasons, tincture contains very high concentrations of Aconitum alkaloids. Despite its high intrinsic toxicity, overdose of aconite tincture by the users has been common. Severe aconite poisoning can be complicated by fatal ventricular tachyarrhythmias and asystole. The public should be repeatedly warned of the danger of taking aconite tincture by mouth.  相似文献

Cytochrome b gene for species identification of the conservation animals   总被引:7,自引:0,他引:7  
A partial DNA sequence of cytochrome b gene was used to identify the remains of endangered animals and species endemic to Taiwan. The conservation of animals species included in this study were: the formosan gem-faced civets, leopard cats, tigers, clouded leopards, lion, formosan muntjacs, formosan sika deers, formosan sambars, formosan serows, water buffalo, formosan pangolins and formosan macaques. The control species used included domestic cats, domestic dogs, domestic sheeps, domestic cattles, domestic pigs and humans. Heteroplasmy was detected in the formosan macaque, domestic pig and domestic cats. The frequencies of heteroplasmy in these animals were about 0.25% (1 in 402bp). Sequences were aligned by Pileup program of GCG computer package, and the phylogenetic tree was constructed by the neighbor-joining method. The results of sequence comparison showed that the percentage range of sequence diversity in the same species was from 0.25 to 2.74%, and that between the different species was from 5.97 to 34.83%. The results of phylogenetic analysis showed that the genetic distance between the different species was from 6.33 to 40.59. Animals of the same species, both the endangered animal species and domestic animals, were clustered together in the neighbor-joining tree. Three unknown samples of animal remains were identified by this system. The partial sequence of cytochrome b gene adopted in this study proved to be usable for animal identification.  相似文献

Although the past decade has witnessed the rise of studies on Chinese evaluations of the police, rural villagers’ assessments of the police remain under-researched. Drawing upon performance theory and survey data from China’s countryside, this study tested whether variations in satisfaction with government performance and life are linked to villagers’ and officials’ trust in county and local/town police. We found that villagers displayed lower levels of trust in the police than local officials. Higher satisfaction with government performance and integrity were associated with greater trust in county police among both villagers and officials. Villagers’ greater satisfaction with crime control and safety led to their stronger trust in both county and town police, but such satisfaction was not significantly related to officials’ trust in both levels of police forces. Rural residents’ generalized trust and particularized trust were associated with a greater likelihood of viewing the police as trustworthy. Meanwhile, female respondents, both villagers and officials, and higher-income officials were more likely to view the police as trustworthy. Directions for future research and policy are discussed.

Drawing on García Coll et al.’s integrative framework and the risk and resilience model, this study examined the relationships between adolescents’ perceived discrimination and psychosocial adjustment and the moderating roles of adolescents’, mothers’, and fathers’ cultural orientations and values, and adolescent gender in a sample of 246 Mexican-origin families. Using multilevel modeling with data from mothers, fathers, seventh graders (M age = 12.8 years; SD = .57 year) and older siblings (M age = 15.7 years; SD = 1.5 years), findings revealed that perceived discrimination was positively related to depression, risky behaviors, and deviant peer affiliations. In addition, parents’ cultural orientations and values and adolescent gender moderated the relationships between perceived discrimination and some indicators of adjustment. These findings suggest that parents’ cultural orientations and values can serve as protective and vulnerability factors in the associations between Mexican-origin adolescents’ perceived discrimination and their psychosocial adjustment.  相似文献
