Effects of amikacin, gentamicin, kanamycin, and streptomycin on renal tissue superoxide dismutase, glutathione peroxidase, glutathione and malondialdehyde, serum creatinine, potassium, sodium, total protein, glucose, uric acid, and total bilirubin levels were investigated. All aminoglycoside antibiotics decreased renal tissue glutathione levels.  相似文献

Pharmacokinetics of Amoxicillin Trihydrate in Desert Sheep and Nubian Goats     

Elsheikh HA  Taha AA  Khalafalla AE  Osman IA  Wasfi IA 《Veterinary research communications》1999,23(8):507-514

The pharmacokinetics of amoxicillin were studied in five Desert sheep and five Nubian goats after intravenous (i.v.) or intramuscular (i.m.) administration of a single dose of 10 mg/kg body weight. Following i.v. injection, the plasma concentration-versus-time data were best described by a two-compartment open model. The kinetic variables were similar in both species except for the volume of the central compartment (V_c), which was larger in sheep (p<0.05). Following i.m. injection, except for the longer half-life time of absorption in goats (p<0.05), there were no significant differences in other pharmacokinetic parameters between sheep and goats. The route of amoxicillin administration had no significant effect on the terminal elimination half-life in either species. The bioavailability of the drug (F) after i.m. administration was high (>0.90) in both species. These results indicate that the pharmacokinetics of amoxicillin did not differ between sheep and goats; furthermore, because of the high availability and short half-life of absorption, the i.m. route gives similar results to the i.v. route. Therefore, identical intramuscular and intravenous dose regimens should be applicable to both species.  相似文献

Favouring Tetranychid mites by intercropping peanut plants on citrus plants and results of chemical control measures The mite populations ofT. cucurbitacearum (Sayed) andT. arabicus (Attiah) reached noxious levels on the peanut plants intercropped on orange trees, during July and August, when the increasing in temperature was accompanied with increasing in humidity. It seems that intercropping the peanut plants on fruit trees and cultural practices may affect as well peanut plant condition as the mortality of mites and consequently increase mite infestation.Regarding, the control experiments, it had been found that 5 acaricides used were very effective in decreasing Tetranychid populations on peanut plants.  相似文献   

Über die molluscizide Wirkung vonBacillus thuringiensis-Präparaten zur biologischen Bekämpfung vonBiomphalaria alexandrina-Schnecken,den Zwischenwirten des Bilharziose-SaugwurmsSchistosoma mansoni in Saudi Arabia

The comparative molluscicidal activity of different preparations ofBacillus thuringiensis as Thuricide, SAN 401, SAN 402 and SAN 415, onB. alexandrina snails was studied. The results showed that different preparations ofBac. thuring. have a remarkable molluscicidal activity onB. alexandrina snails. However, the obtained results proved thatBac. thuring. with its preparation SAN 415 was the most effective in killing the snails comparing with the other preparations at the same experimental condition. Prolonged exposure ofB. alexandrina to subletal concentration (250 ppm) of SAN 415 delayed its ovipositary activity. Increasing the dose to 500 ppm resulted in a complete loss of egg production. Comparatively exposure of snail groups to the same doses of Thuricide, SAN 401 and SAN 402 resulted only in decreasing its egg laying capacity. These results proved the high potentially effectiveness ofBac. thuring. in its preparation SAN 415 as a biological control agent forB. alexandrina snails. The wayes by which this biological agent acts on the reproductive system of the snails were discussed.  相似文献

Prenatal Metanephrogenesis of The Camel: Morphological Evidence of Epithelial–Mesenchymal Interaction

The present investigation examined histogenesis of epithelial, stromal and angiogenic elements of the prenatal camel permanent or metanephric kidney. The primitive metanephros was first observed at the 13‐mm crown vertebral rump length (CVRL) stage as an ovoid structure composed of a centrally located epithelial ureteric bud and peripheral circumscribed masses of undifferentiated mesenchymal cells. The first morphological evidence of glomerulogenesis was observed at the 28‐mm CVRL stage. Developing renal corpuscles became obvious at the 35‐mm CVRL stage. At the 60‐mm CVRL stage, the epithelial renal pelvis gave rise to tubular branches that extended towards the cortical zone. These branches represented the presumptive collecting ducts. Differentiation of renal tubules into the proximal and distal convoluted tubules was observed at the 95‐mm CVRL stage. At the 130‐mm CVRL stage, the renal medulla was clearly delineated into medullary pyramids, which in association with the corresponding cortical caps formed the morphological basis of the renal lobar formation. A gradual nephrogenic decline was noticed from the 940‐mm CVRL on; however, the process of nephrogenesis persisted throughout all the studied foetal stages.  相似文献
