In this study, alteration in the follicular fluid composition and luteal function was investigated in the buffalo with endometritis. Genitalia were classified into cytological and purulent endometritis on the basis of polymorphonuclear cell cut off while non‐endometritis served as control (n = 10/group). In the follicular phase, the number of surface follicles was counted, diameter of the largest follicle was measured and the follicular fluid was assayed for total protein, cholesterol, malondialdehyde (MDA), total antioxidant capacity (TAC), oestradiol (E2) and progesterone (P4). The P4 content of corpus luteum during mid‐luteal phase was estimated by radioimmunoassay. Ovaries from the follicular phase of oestrous cycle showed no significant difference in the total number of surface follicles, size of the largest follicle and volume of follicular fluid in the buffaloes with and without endometritis (p > .05). However, the antral fluid of the largest follicle from the genitalia of buffalo with cytological and purulent endometritis showed a significant decrease in the concentration of total protein, cholesterol, TAC and E2 and a significant increase in the concentration of MDA and P4 (p < .05). The results indicated that there is an association between endometritis and decreased ovarian function. 相似文献

ABSTRACTAim: To evaluate the sedative and clinical effects of I/V xylazine, detomidine, medetomidine and dexmedetomidine in miniature donkeys.Methods: Seven clinically healthy, male adult miniature donkeys with a mean age of 6 years and weight of 105?kg, were assigned to five I/V treatments in a randomised, cross-over design. They received either 1.1?mg/kg xylazine, 20?μg/kg detomidine, 10?μg/kg medetomidine, 5?μg/kg dexmedetomidine or saline, with a washout period of ≥7 days. The degree of sedation was scored using a 4-point scale by three observers, and heart rate (HR), respiration rate (RR), rectal temperature and capillary refill time (CRT) were recorded immediately before and 5, 10, 15, 30, 60, 90 and 120 minutes after drug administration.Results: All saline-treated donkeys showed no sedation at any time, whereas the donkeys treated with xylazine, detomidine, medetomidine and dexmedetomidine had mild or moderate sedation between 5 and 60 minutes after treatment, and no sedation after 90 minutes. All animals recovered from sedation without complication within 2 hours. The mean HR and RR of saline-treated donkeys did not change between 0 and 120 minutes after administration, but the mean HR and RR of donkeys treated with xylazine, detomidine, medetomidine and dexmedetomidine declined between 5 and 60 minutes after drug administration. The mean rectal temperature of all treated donkeys did not change between 0 and 120 minutes after administration. The CRT for all donkeys was ≤2 seconds at all times following each treatment.Conclusions and clinical relevance: Administration of xylazine at 1.1?mg/kg, detomidine at 20?μg/kg, medetomidine at 10?μg/kg and dexmedetomidine at 5?μg/kg resulted in similar sedation in miniature donkeys. Therefore any of the studied drugs could be used for sedation in healthy miniature donkeys. 相似文献

A set of well-drained soils in Galicia, formed from gabbros, amphibolites and schists, with udic moisture and mesic temperature regimes, are studied. All but one of the surface horizons show an'exchange complex dominated by amorphous material'(ECDAM); consequently, most soils are classified as Andosols (FAO) or as different subgroups of Dystrandepts (Soil Taxonomy). The soils on gabbros and amphibolites frequently have'andic properties'so, following the ICOMAND proposals, five of the 12 soils studied may be characterized as Andisols. Many of the five soils have properties comparable to those of soils from volcanic areas, especially to those called'non-allophanic Andosols', which have an abundance of active-Al, mainly in the form of Al-humus complexes. 相似文献

Abstract CASE HISTORY: A 10-year-old Friesian dairy cow presented with a history of weight loss, decreased milk production and fluid splashing on auscultation of the heart. Previous antibiotic therapy included oxytetracycline, marbofloxacin and penicillin. CLINICAL AND PATHOLOGICAL FINDINGS: Following a failure to respond to treatment, prescribed by the referring veterinarian for respiratory infection and septic arthritis, the cow was referred to Massey University Veterinary Teaching Hospital with suspected pericarditis. Clinical examination identified a predominantly left sided holodiastolic heart murmur with tachycardia and cording of the jugular veins. Cardiac ultrasound showed an enlarged aortic valve with turbulent blood flow and regurgitation, consistent with bacterial endocarditis. Blood culture demonstrated Paenibacillus spp. Due to the severity of the clinical signs and poor prognosis, euthanasia was performed and a post-mortem examination carried out. DIAGNOSIS: Traumatic reticuloperitonitis with abscessation of the reticulum and rumen wall, which progressed to a bacteraemia and presumptively caused endocarditis, endometritis, septic arthritis, and renal and myocardial infarcts due to emboli from the endocarditis lesions. CLINICAL RELEVANCE: New Zealand dairy cattle are at risk of traumatic reticuloperitonitis and due to varying presentations diagnosis can be complicated. Subsequent bacteraemia is common and in this case the novel bacterial species Paenibacillus was implicated as a potential pathogen. 相似文献

In this study, the effects of aqueous extracts from Zygophyllum fabago L. on two plant phytopathogenic fungal species (namely, Fusarium oxyosporum f. sp. melonis and Pythium aphanidermatum) were studied under laboratory conditions. The plant extracts (10% w/v) were prepared by using deionized water and fresh tissues. Dilutions (2, 4, 6, and 8% w/v) were obtained to test their effect on the mycelial growth of the phytopathogenic species. Additionally, the recovery of the fungi after their exposure to the Z. fabago extract was analyzed. The plant extracts inhibited the growth of F. oxyosporum and P. aphanidermatum (the maximum mean inhibition that was recorded with the 10% w/v extracts was 42.9% and 85.3%, respectively). A second series of experiments demonstrated the existence of residual effects in both species. The amount of residual inhibition by the 10% w/v extracts was 28.6% in F. oxyosporum and 53.8% in P. aphanidermatum. A dose–response was clearly observed in P. aphanidermatum, while an increase in extract concentration was not associated with a significantly greater reduction in the growth of F. oxyosporum. These findings give insights into the potential of Z. fabago as a growth inhibitor of F. oxyosporum and P. aphanidermatum, thus suggesting an interesting potential role for this common weed as a source of natural fungicides. 相似文献
