An alcoholic extract of Solanum dulcamara L., a plant widely used in folk medicine for treating cancers and warts, shows tumor-inhibitory activity against Sarcoma 180 in mice. Systematic fractionation of the extract has led to isolation and characterization of beta-solamarine as an active principle.  相似文献   

The hawaii to tahiti shuttle experiment     

Wyrtki K  Firing E  Halpern D  Knox R  McNally GJ  Patzert WC  Stroup ED  Taft BA  Williams R 《Science (New York, N.Y.)》1981,211(4477):22-28

The Shuttle Experiment conducted between Hawaii and Tahiti from January 1979 to June 1980 was designed to observe the changing equatorial ocean structure and circulation, to study the variations and interactions of the four major equatorial ocean currents, and to develop a scientific basis for their monitoring by simple observations of thermal structure and sea level. Preliminary analyses of the results show that the equatorial thermal structure remains intact during a normal year and that only the positions and intensities of the currents are subject to change. The water transport of the equatorial undercurrent varied from 25 x 10(6) cubic meters per second in January to 51 x 10(6) cubic meters per second in July, but also exhibited strong short-term pulsations. The equatorial surface flow responded strongly to the winds at periods of 1 month and longer. An array of drifter buoys in the equatoral countercurrent was subject to very little dispersion while traveling over 4500 kilometers in 4 months. Low-frequency fluctuations in the North Equatorial Countercurrent can be monitored by means of the difference in sea level between Fanning and Majuro.  相似文献

Toxicosis in newborn pigs associated with cutaneous application of an aerosol spray containing chlorpyrifos     

A B Scheidt  G G Long  K Knox  S E Hubbard 《Journal of the American Veterinary Medical Association》1987,191(11):1410-1412

Weakness, lethargy, ataxia, lateral recumbency, limb paddling, tremors, salivation, and diarrhea were observed in newborn pigs on a commercial swine farm. Many pigs became moribund and died. All had been treated with an aerosol wound spray containing 2.5% chlorpyrifos. A controlled study was undertaken to determine whether the aerosol spray was the cause of these clinical signs. Pigs exposed to aerosol spray containing 2.5% chlorpyrifos at 3 hours (n = 4) and 6 hours (n = 3) after birth developed clinical signs similar to those on the farm; none survived. Pigs exposed at 24 hours (n = 5) after birth developed clinical signs consistent with those that had developed in pigs on the farm; 3 died and 2 survived. Of 3 pigs exposed to the same spray at 36 hours after birth, 1 developed tremors 7.5 hours later and diarrhea 9 hours later, then returned to normal.  相似文献

Glacial age marsh, lafayette park, washington, d.C     

Knox AS 《Science (New York, N.Y.)》1969,165(3895):795-797

Organic sediments beneath historic Lafayette Park mark the site of a freshwater marsh which bordered the Potomac River when it was 15 meters above its present level. Plant microfossils and ice-rafted boulders indicate a climate much colder than now. The carbon-14 age of more than 45,000 years and palynological studies suggest an early Wisconsin age.  相似文献
