[14C]metalaxyl applied to seeds, roots and leaves of cowpea was readily taken up by all plant parts and a major fraction of it was retained within the treated leaves and seeds but not in the roots. The fungicide exhibited ambimobility inside the plant. When applied to the middle of leaflets, metalaxyl mobilised towards proximal and distal parts of the leaflet. Intraleaflet movement seemed to result from translocation through veins and diffusion through cell walls and intercellular spaces. Accumulation of metalaxyl at tips and margins of primary leaves followed application to roots. Metalaxyl was readily extracted from most plant parts except cotyledons and only 0.8% of the fungicide applied as a seed treatment was recovered from 50-day-old plants. 相似文献

Twenty-six pigs from four litters in a healthy herd of swine were examined periodically for the fecal excretion of viruses by the use of porcine kidney cell cultures. Viruses were initially isolated from all pigs between 34 to 64 days of age. The pigs within each litter began shedding virus in their feces approximately at the same time, usually within one week, and the type of virus initially recovered was usually the same. Subsequently, waves of infection with different enteroviruses appeared to occur during the observation period of six months. At least six antigenically different viruses were isolated from this herd over a 26-month period. Most, if not all, of these viruses were considered to belong to the enterovirus group. No disease was associated with these enteroviral infections.
The colostrum and milk of sows contained significant amounts of enteroviral antibodies. Prior to nursing, the serum of new-born pig contained no enteroviral antibodies but, shortly after nursing, high titers of such antibodies were present in the serum. Antibodies were detected in the feces of suckling pigs.

TREATMENT OF DIAPHRAGMATIC HERNIA IN BUFFALOES 总被引:2,自引:0,他引:2
J. Singh B. Prasad R. Kumar R. N. Kohli S. S. Rathor 《Australian veterinary journal》1977,53(10):473-475
The surgical treatment of diaphragmatic hernia attempted on 19 lactating buffaloes is described. Thirteen cases recovered uneventfully, 1 recovered after developing brisket oedema and 5 died, 3 during surgery and 2 postoperatively. The desired depth of anaesthesia was achieved by the administration of 6% chloral hydrate followed by 5% thiopentone sodium. A postxiphoid approach and the use of a continuous lock stitch suture were preferred to repair the vent in the diaphragm. Pre- and post-operative use of hydrocortisones and fluids and sufficient tissue oxygenation by controlled positive pressure respiration are believed to be keys to the success of the treatment adopted. 相似文献
