This study describes the morphometry of the testicles of captive coatis (Nasua nasua) and verifies the existence of correlations between the testicles and the semen producing characteristics. Twelve ejaculates were obtained from five adult specimens that were restraint by anaesthesia. Visual and morphometric evaluation of the external genitalia was performed by using a caliper. The animals presented a scrotal circumference of 9.4 ± 0.7 cm. The right testicle presented a width of 1.7 ± 0.2 cm, length of 2.6 ± 0.2 cm and volume of 3.9 ± 1.1 cm3. The left testicle presented a width of 1.7 ± 0.1 cm, length of 2.5 ± 0.3 cm and volume of 3.6 ± 0.7 cm3. No significant correlations were obtained between the scrotal circumference or total testicular volume and the semen producing characteristics (volume and sperm concentration). For the first time in this field, this study presents an important contribution to the knowledge of the reproductive morphophysiology of coatis. 相似文献

Intravenous immunoglobulin (IVGG) was administered to 13 of 37 dogs with immune-mediated hemolytic anemia. All dogs received concurrent prednisone therapy, 14 dogs also received cyclophosphamide; and a single dog each received cyclosporine, azathioprines, and danazol. Dogs that responded to prednisone therapy without IVGG generally did so within 7 days (mean ± standard deviation = 5.6 ± 2.9 days). Intravenous immunoglobulin was administered after 10.4 ± 6.6 days of prednisone therapy as an intravenous infusion of 0.5 g/kg (range 0.25 to 0.73 g/kg). Eleven dogs received a single treatment, 2 dogs each received 2 treatments. No relevant adverse effects were noted. Eleven dogs had an increase in PCV of at least 4% 2.2 ±1.5 days after IVGG infusion. In 10 of these dogs, the PCV continued to increase until the time of hospital discharge. One responder died 1 hour after the increase in PCV, 1 dog was euthanized within 24 hours of IVGG administration, and 1 dog had no response over a period of 13 days. Results of this study suggest that IVGG therapy may be of value in dogs with immune-mediated hemolytic anemia that do not respond within 7 days of appropriate corticosteroid therapy. 相似文献

Geeldikkop was induced in sheep by the oral administration of crude steroidal saponins from Tribulus terrestris. Two of the sheep developed typical lesions of geeldikkop, including birefringent crystalloid material in bile ducts and concentric periductal lamellar fibrosis. The clinical pathological changes in these sheep were also consistent with those of geeldikkop: aspartate transaminase and gamma-glutamyl transferase activities in the sera of both were elevated, and one had bilirubinaemia. A third sheep became photosensitive without typical lesions of geeldikkop in the liver or changes in the activities of liver enzymes before euthanasia. The findings of these trials are consistent with reports from abroad that ovine hepatogenous photosensitization, caused by Agave lechuguilla and Narthecium ossifragum, can be induced with crude saponins from the respective plants. 相似文献

A qualitative and quantitative survey was made of the aerospora above an Eragrostis curvula (Schrad.) Nees pasture. The pasture, which lay adjacent to a field of Panicum coloratum L. where an outbread of ovine photosensitivity had occurred, was not grazed during the survey. A Burkard volumetric spore trap was used to sample the aerospora continuously for 10 months. Twenty components of the aerospora were recognized: spores of 9 genera of fungi (Cladosporium, Alternaria, Epicoccum, Drechslera, Pithomyces chartarum (Berk. & Curt.) M. B. Ellis, Nigrospora, Sporormia, Curvularia, Spegazzinia); 8 recognizable but unidentified spore types; hyphal fragments and pollen grains. Cladosporium conidia comprised 83,37% of the total aerospora. Conidia of Pithomyces chartarum formed a small (0,29%) but significant component of the aerospora, since this fungus is known to cause hepatogenous photosensitivity. 相似文献

Three toxic bufadienolides , one characterized as hellibrigenin 3-acetate, have been isolated from Kalanchoe lanceolata Forsk. Typical signs of cardiac glycoside poisoning, involving the gastro-intestinal, neuromuscular and cardiovascular systems, could be induced by drenching the milled plant to sheep. Such signs could also be induced by dosing the bufadienolides to sheep or by injecting them into both guinea-pigs (subcutaneously) and sheep (intravenously). The specific paretic syndrome, krimpsiekte , on the other hand, was reproduced only by the repeated intravenous administration of smaller doses of the 2 unknown bufadienolides to sheep. Histopathological examination revealed a mild to severe multifocal cardiomyopathy in sheep receiving plant material or bufadienolides . 相似文献
