Fusarium oxysporum f. sp. lycopersici elicitor (EFOL-2) treatment induces cytosolic influx of calcium in Fusarium-resistant tomato suspension culture. The calcium signature was found to be biphasic, which is characteristic of recognition
of oligosaccharides in the elicitor preparation. Further, several lines of evidence such as, (i) attainment of saturation
level of the [Ca2+]cyt at a definite extra-cellular calcium concentration (ii) prominent reduction in EFOL-2-induced influx in [Ca2+]cyt on treatment with the calcium channel blockers verapamil and diltiazem and (iii) establishment of a refractory stage of [Ca2+]cyt level upon repeated stimulation by EFOL-2, is indicative of receptor-mediated activation of the calcium channel for cytosolic
elevation. In addition, inhibition of EFOL-2-induced [Ca2+]cyt increase by protein kinase inhibitor staurosporine and wortmannin indicate phosphorylation is a regulatory event of calcium
influx. Additionally, monitoring of cell death on EFOL-2 treatment indicated that the degree of ROS generation is not capable
of inducing cell death. Inhibition of ROS generation on two separate occasions such as, calcium-free media and on treatment
with inhibitors causing calcium channel occlusion revealed ROS generation as a successive event of calcium influx. 相似文献

Summary The anaesthetic effects of intravenous tiletamine-zolazepam 6.6 mg/kg-ketamine 6.6 mg/kg (TK) and tiletamine-zolazepam 6.6 mg/kg-ketamine 6.6 mg/kg-xylazine 0.11 mg/kg (TKX) were evaluated in six wethers. Heart rate, respiration rate, arterial blood pressure, and the electrocardiogram were monitored during anaesthesia. Analgesia was tested by electrical stimulation in the left flank. Atropine (0.03 mg/kg) was given intramuscularly before induction, but after recording of baseline heart rate and respiratory rate. The duration of analgesia was 28.7 ± 6.9 min with TK and 82.8 ± 26.6 min with TKX. Heart rate increased significantly within 5 min after TK or TKX administration. Respiratory rate remained unchanged after TK administration, but increased significantly from 5 to 45 min after TKX administration. Arterial blood pressure decreased significantly at 15 min with TK and 30 min with TKX. Sheep remained recumbent for 201 min with TK and 166 min with TKX. All recovered uneventfully. We conclude that either TK or TKX may be used for anaesthetising sheep. 相似文献

Seed of Adonis microcarpa (pheasant's eye) fed at 5.6 g/kg of the diet induced virtually total feed refusal within 3 d in growing and finishing pigs. It also caused vomiting, rapid and shallow breathing and death in a minority. These effects were probably caused by cardiac glycosides whose structure and effects closely resemble those of digoxin. Feed intake and growth recovered within 2 weeks of removal of the seed. 相似文献

A simple method using tissue extraction of Copper (Cu) in 8M nitric acid for 45 minutes at 100 degrees C, followed by sample dilution and Cu quantitation by flame atomic absorption spectroscopy is described. The detection limit of the method is 16 micromol Cu/kg liver. The mean recovery of added Cu was 100.4%. This method for liver copper analysis correlated well with a method using nitric/perchloric acid digestion and atomic absorption spectroscopy (r2 = .986) and is faster, less expensive and less hazardous. 相似文献

In determining the effect of prior feeding of antimicrobials on subsequent antimicrobial therapy in induced colibacillosis of piglets with Escherichia coli serotype O62 (Dey et al., 1977), study groups in one trial developed spontaneous colibacillosis due to a different Escherichia coli serotype O147. This paper reports the results and conclusion drawn from this outbreak.
Both groups, irrespective of antimicrobial feeding, developed disease, and the attack rates for the groups were not significantly different. Neither mortality nor the clinical course of illness in animals without therapy changed significantly as a function of antimicrobial feeding. The antimicrobial feeding had no effect on the therapeutic efficacies of chloramphenicol or chlortetracycline utilized for treating the disease. Chloramphenicol therapy was more effective in terminating the disease. 相似文献
