Summary Electrolysis of salt solutions produces mortality of a plant-parasitic nematodeMeloidogyne incognita. The mortality depends on the nature and amount of the, products of electrochemical reactions and is enhanced in presence of Cu-electrodes. Application of magnetic fields on electric fields alters nematode mortality in ferro-magnetic electrolytes. 相似文献

Summary Fermentation of leafy food occurs in the enlarged saccus gastricus of the colobus monkey with the formation of volatile fatty acid, as in the rumen of ruminant animals. About half of the digestible organic matter and cellulose of the diet is digested in this way.We wish to thank the Inter-University Council, the Nuffield Foundation and the Wellcome Trust for financial support. MrP. J. S. Dewey kindly made the determinations of cellulose and lignin. 相似文献

With the aid of thymidine-H3 autoradiography gliogenesis in the rat brain was seen to start during embryonic stages, which might continue into the postnatal stages of development. Gliogenesis followed a caudo-rostral gradient closely following neurogenesis. Ependymogenesis was found to occur in parallel with gliogenesis. 相似文献

Summary Laboratory populations of German cockroach reared on food treated with R-20458 (75 ppm) or Ro 20-3600 (3000 ppm) became completely sterile and eventually extinct. The hypertrophied oocytes had excessively laid chorion, and the hypertrophied accessory sex glands contained excessive amounts of protein. 相似文献

Summary Binucleated neurons were studied in the central nervous system of the rat and the rabbit. They were present in the young as well as the adult animals. The animals injected with thymidine-H3 during their embryonic development showed labelled binucleated neurons. It is suggested that the neurons become binucleated during neuroembryogenesis, and differentiate into normal neurons morphologically and physiologically.Supported by NIH Research grant No. NS-08817-05. 相似文献

Summary The variation in chromosome size in root-tip meristem ofPuschkinia libanotica L. was studied at different days of root growth with special attention to DNA, RNA, total protein and histone contents. The results show that the size and organisation of chromosomes even within the one tissue is subject to considerable change during growth and development.The author is thankful to Prof. H. Rees, FRS, Department of Agricultural Botany, University College of Wales, Aberystwyth, Wales, U.K., for his guidance and to University College of Wales, Aberystwyth, for granting him a SRC fellowship. 相似文献
