This study reports a protocol for successful micropropagation of Penthorum chinense using nodal explants on Murashige and Skoog (MS) medium supplemented with 6-benzyladenine (BA) or kinetin (Kn). The presence of BA promoted a higher rate of shoot multiplication than Kn. Maximum multiple shoot formation was observed in 59.2% of nodal explants cultured on MS(More)
Ischemic injury in rodent models reliably leads to the activation of microglia, which might play a detrimental role in neuronal survival. Our preliminary studies suggest that nicotine plays a potential role in decreasing the numbers of cultured microglia in vitro. In the present study, we found treatment with nicotine 2, 6, and 12 h after ischemia for 7(More)
Pulmonary function tests were performed pre and post workshift on 887 textile workers with at least two years of employment in two cotton mills and one silk mill in Shanghai, the People's Republic of China. Environmental sampling was performed with vertical elutriators, and pulmonary function was performed with standardized techniques. Cotton textile(More)
Cross-sectional studies were conducted during 1981-1983 among 861 textile workers in 3 cotton mills and 822 controls in 2 silk factories. Questionnaire and lung function tests were taken and inhalable dust concentrations were measured. Prevalence of byssinosis was 5.6%. Average dust concentrations were highest in carding rooms, 1.47-1.99 mg/m3. The(More)
OBJECTIVE To study the effects of strychnos alkaloids on the proliferation of adult rat neuroprogenitor cells. METHODS Strychnos alkaloids free of strychnine and brucine were extracted from Strychnos nux vomica, and the effects of Strychnos alkaloids on the survival of HEK293 and PC12 cells were evaluated using MTT assay. In vitro cultured adult rat(More)

Using tracer technique of 14C isotope, toxicokinetics of fenvalerate was studied in rats and mice. The results strongly suggested the existence of distinct differences between species in mammals in the metabolism of 14C-fenvalerate. The absorption and elimination of 14C-fenvalerate in the blood of mice following single intragastric administration was faster(More)
