Fifteen plant species were collected from the Nelspruit Botanical Garden based on a list of plants provided by Phytomedicine Programme at the University of Pretoria and their ethnopharmacological information. Hexane, dichloromethane (DCM), acetone and methanolic extracts were screened for antimycobacterial activity against Mycobacterium smegmatis. The acetone extract of Milletia stulhimannii was the most active, showing activity against Mycobacterium smegmatis with minimum inhibitory concentration (MIC) value of 0.13 mg/ml. Acetone extracts for all plants had lower MIC values ranging between 0.11–1.25 mg/ml against M. smegmatis. Milletia stulhimannii, Albizia gummifera, Xanthocercis zambesiaca and Barringtonia racemosa have shown great potential as anti-tuberculosis agents. They were active against M. smegmatis with average MIC values of acetone extracts of 0.13 mg/ml.  相似文献

Background It has been shown that as immigrants’ length of residence increases, so does their weight. However, little is known about factors associated with weight status among Chinese Americans, one of the fastest growing immigrant populations in the US. Methods Baseline data from a National Cancer Institute-funded longitudinal study involving a multi-stage probability sample of Chinese Americans residing in two communities in New York City were collected. Results Chinese Americans had a low BMI (mean = 22.81) and a lower proportion of obese individuals compared with other ethnic groups in the US reported in the literature. While the prevalence of being overweight (21%) and obese (2%) was low, length of residence was positively associated with weight status (P < 0.005). Conclusions Innovative strategies to help Chinese Americans maintain healthy weight status and to prevent them from becoming overweight and obese are needed.  相似文献

Crown fractures and luxations occur most frequently of all dental injuries. An appropriate treatment plan after an injury is important for a good prognosis. Guidelines are useful for delivering the best care possible in an efficient manner. The International Association of Dental Traumatology (IADT) has developed a consensus statement after a review of the dental literature and group discussions. Experienced researchers and clinicians from various specialties were included in the group. In cases where the data did not appear conclusive, recommendations were based on the consensus opinion of the IADT board members. The guidelines represent the current best evidence, based on literature research and professional opinion. In this first article of three, the IADT Guidelines for management of fractures and luxations of permanent teeth will be presented.  相似文献
