Effects of Three Drugs on Membrane Metabolism Against Cysticerci cellulosae in vitro

To investigate the effects and mechanisms of the benzimidazole carbamate and benmidine drugs on Cysticerci cellulosae and choose effective drugs on Cysticerci cellulosae, the membrane metabolism of Cysticerci cellulosae in vitro was tested after three kinds of drugs which were used respectively. The indexes included the contents of lipids, the contents of SA and the changes of the membrane fluidity. The results showed that oxfendazole could inhibit the membrane metabolism of immature and mature Cysticerci cellulosae in vitro, and albendazole only inhibited the mature one, while thibendimidine neither acted on the immature nor mature one.     

棉花不同时期去叶源对库源关系影响的初步研究

通过对棉花不同时期去主茎叶、叶枝叶、果枝叶和全部叶片的研究,初步探讨了棉花叶源对库的影响.结果表明:无论蕾期还是盛铃期,叶片是棉花光合产物的主要来源,没有叶片棉花就不能正常生长,也很难保证其产量;不同部位的叶片中,主茎叶的作用显著,蕾期去主茎叶后株高日增长量减少0.5 cm以上,干物质积累明显下降,盛铃期则导致棉铃大量脱落,成铃平均减少2个以上;去果枝叶的作用相对较小,去叶枝叶几乎无影响.

Factors influencing decline in soil pH in Hawaiian Eucalyptus and Albizia plantations

Soil pH declined from 5.9 to 5.0 in 8 years beneath plantations of Eucalyptus saligna (Sm.) in Hawaii. In stands of Albizia falcataria, (L.) Fosberg, the soil pH change was more dramatic, declining from 5.9 to 4.6. We measured several components of soil acidity beneath four mixtures of the two tree species to gain insight on the processes responsible for the decline in soil pH. These components were studied using an empirical method of comparing acid quantity, degree of neutralization (depletion of base cations), and acid strength. The decline in soil pH differed between species as a result of differences in the degree of neutralization of the soil exchange complex; the larger decrease in soil pH under Albizia was produced by greater acidification of the exchange complex. Empirical titration curves suggested that differences in acid strength moderated the divergence in soil pH beneath the species. Had the acids accumulating in the soil under Albizia been as strong as those in the Eucalyptus soil, the difference in soil pH would have been greater. Though the two species had contrasting effects on soil pH, the differences in degree of neutralization, responsible for the pH decline, were small compared with differences in the amount of cations stored in tree biomass. Continued supply of nutrient cations (from weathering or fertilization) will ultimately control both the extent of soil pH decline and the level of productivity sustained by the forest.     

Studies on mutlispecific resistance of gastrointestinal nematodes to benzimidazoles on dairy-goat farms

Multispecific resistance to benzimidazoles was studied in three selected farms. These farms had bred dairy goats for more than 15 years. The helminths were introduced with the goats at the establishment of the farms which afterwards remained isolated. Nematode resistance could then be related to their own management practices. Faecal egg count tests and egg hatch assays were performed to assess intensity of resistance. The generic (infective larvae in faecal cultures) and specific richness (adult worms) were assessed. The resistant species were Trichostrongylus colubriformis, Teladorsagia circumcincta, Haemonchus contortus and Oesophagostomum venulosum. Faecal egg count reduction tests and egg-hatch assays did not match exactly. Faecal larval counts after treatments gave a distorted picture of multispecific resistance: Haemonchus and Oesophagostomum were very largely over represented. The number of species found in the three farms was relatively low compared with other reports in goat farms of the area. This reduction of diversity might also be due in part to characteristics of breeding management and history (use of permanent pasture and introduction of goats at the establishment of farm).     

3种农药的微核效应研究
