The sacrum fused with ilium in a chinese water deer (Hydropotes inermis) was observed. The sacrum consists of four sacral vertebrae which was fused each other. In the ventral part of the fused pelvis, on the left, there was a 20.19 mm gap at the dorsolateral part of the sacroiliac articular part which is in between the promontory and the cranial border of the first ventral sacral foramen. On the right, there was a 14.34 mm gap at the dorsal part of sacroiliac articulation. In the dorsal view of the fused pelvis, the wing of sacrum and the wing of ilium were fused tightly, so that the boundary of the two bones was not recognizable.

We studied the effects of trazodone on arterial blood pressure in anesthesized guinea pigs, and on vascular responses in isolated thoracic aorta. Trazodone produced a concentration-dependent relaxation in phenylephrine-precontracted endothelium intact (+E) rings, but not in a KCl-precontracted aortic rings. These relaxant effects of trazodone on +E rings were siginificantly greater than those on denuded (-E) rings. The trazodone-induced relaxation was suppressed by gilbenclamide and tetrabutylammonium, but not by N(G)-nitro-L-arginine (L-NNA), N(omega)-nitro-L-arginine methyl ester (L-NAME), methylene blue (MB), nifedipine, indomethacin, 2-nitro-4-carboxyphenyl-n,n-diphenylcarbamate (NCDC) and clotrimazole. In vivo, infusion of trazodone elicited a significant decrease in arterial blood pressure.

The major protocol features of the rodent uterotrophic assay have been evaluated using a range of reference chemicals. The protocol variables considered include the selection of the test species and route of chemical administration, the age of the test animals, the maintenance diet used, and the specificity of the assay for estrogens. The rodents were ovarjectomized under general anesthesia via bilateral flank incisions and randomly assigned to groups of 5 animals. Chemicals were DEHP, DBP, BPA and NP, were injected sc once daily with combinations of chemicals treatments for 3 days.

Melatonin, the principal hormone of the vertebral pineal gland, participates in the regulation of cardiovascular system in vitro and in vivo. Lithium inhibits both inositol polyphosphate phosphatase (IPPase) and inositol monophosphatase (IMPase), which are involved in a wide range of signal transduction pathways. The aim of the present study was to assess the effect of lithium on endothelial-dependent relaxation to melatonin and on the melatonin-induced inhibition of contraction by phenylephrine (PE) in isolated rat aorta. Melatonin induced a concentration-dependent relaxation in PE-precontracted in endothelium-intact (+E) aortic rings.

The present study was conducted to investigate biochemical characteristics and antimicrobial susceptibility of Aeromonas hydrophilia isolated from Jackass penguins (Spheniscus demersus) of zoo and capelins (Mallotus villosus). Seven of Jackass penguins showed anorexia, depression with seriously greenish vomiting for a few days, but resulted in 4 deaths although extensive treatment was carried out by zoo veterinarians. From the 18 samples composed of organs of feces from dead or live Jackass penguins and capelins, 4 (22.2%) Aeromonas hydrophilia were isolated and Bacillus spp, Staphylococcus aureus, Staphylococcus auricularis, Staphylococcus cohnii and Enterobacter aminigenus were also identified.

The purpose of this study is to establish the analgesic effects of electroacupuncture for Korean native goat. Electroacupuncture was applied to the 6 Korean native goats. In 3 of them, rumenotomy was performed, and in the other 3, laparotomy was done. The analgesic induction time was 15 to 30 minutes. The acupoints used were Tian-ping (Celestial Peace, GV-5), Bai-hui (Hundred Meetings, GV-20), left 13th thoracic nerve and left 3rd lumbar nerve. Electroacupuncture was performed in lateral recumbency. Needles were inserted 1-2 cm deep, and connected to the electroacupuncture apparatus. The electrical stimulation condition was 30 Hz and 2-6 volts.

An abattoir study on the abdominal fat necrosis in adult cattle was performed pathologically. Grossly, masses of fat necrosis were leekgreen in colour, lobulated on the cut surface, and saponificated in the texture. These necrotic adipose tissues infiltrated usually into neighboring parenchymal organs including intestines and pancreas, leading to fibrosis or atrophy of them. Histopathologically, necrotic fat cells contained acidophilic, opaque, amorphous substance or basophilic fibrillar or granular minerals in their cytoplasms. The lesions of fat necrosis were divided by fibroconnective tissue. With increase of the severity, necrotic fat cells fused each other and then formed fat cysts.

The disease causing colic is the greatest cause of deathe in the domestic horse population today and accidental deaths as a result of colic leads to decreased productivity and economic losses in the horse breeding industry. Large colon impaction is the most common cause of colic in horses. Horses may ingest sand either by eating from the ground in sandy locations, or because of its inclusion in hay. In certain areas sand impaction is relatively common. The horse (4 year, female) presented with abdominal pain, which was charactered by willing to lie down, pawing, and looking at flank. A month later, the horse died suddenly at sand paddock.

To evaluate site-to-site variation within fecal pats from cattle with regard to detection of Escherichia coli O157 and determine the effect on the accuracy of prevalence estimates of assay of multiple samples collected from the same fecal pat. 120 freshly voided fecal pats collected from 2 beef feedlots. Procedures-5 samples were systematically collected from each fecal pat and analyzed for E coli O157 via selective preenrichment techniques, immunomagnetic separation, and biochemical tests. Presumptive isolates were definitively identified via agglutination assays and polymerase chain reaction techniques. Best estimators of prevalence were calculated from the distribution of E coli O157-positive samples per pat. Of the 120 fecal pats, 96, 13, 4, 2, 3, and 2 fecal pats had 0, 1, 2, 3, 4, and 5 E coli O157-positive samples, respectively. The greatest estimate of E coli O157 prevalence (20%) was achieved when all 5 samples were assessed; this estimate represented a 2.4- fold increase in prevalence, compared with that provided via analysis of 1 sample/pat (8.2%). Compared with assessment of 5 sites/pat, the relative sensitivity of detecting an E coli O157-positive fecal pat via analysis of 1 site/pat was 40.1%. Results suggest that estimates of E coli O157 prevalence derived from sampling of 1 location/pat are likely underestimates of the true prevalence of this pathogen in fecal pats (and by extension, cattle). Additional research is warranted to confirm these results in situations of high and low prevalence and across different feedlots.

Lumpy skin disease (LSD) is a disease of cattle, primarily in Africa and Madagascar and rarely in the Middle East. It is caused by a capripoxvirus that belongs to the family Poxviridae. The disease is of economic importance in endemic areas. Effective control of LSD requires accurate and rapid laboratory techniques to confirm a tentative clinical diagnosis. Comparative studies on different diagnostic tests used at different stages of the disease have not been done. The aim of this study was to compare several of these tests. Six seronegative bulls, between 11 and 20 months of age, were infected intravenously and kept in an insect-free facility. The course of the infection was monitored. During a 3-month period blood samples and skin biopsies were collected for virus isolation and polymerase chain reaction (PCR). Skin biopsies were also examined using transmission electron microscopy (TEM). The incubation period in infected animals varied from 4-5 days. The length of the viraemic period did not correlate with the severity of clinical disease. Viraemia was detected from 1-12 days using virus isolation and from 4-11 days using the PCR, which is longer than has previously been reported. Virus was isolated from skin biopsies until Day 39 post infection (p.i.) and PCR could demonstrate viral DNA until Day 92 p.i. Transmission electron microscopy of negatively stained skin biopsies detected LSD virus only in one of the four bulls that developed skin lesions until Day 33 p.i. The PCR was a fast and sensitive method to demonstrate viral DNA in blood and skin samples. It could detect viral nucleic acid in skin lesions 53 days longer than virus isolation. Virus isolation from blood and skin samples was sensitive and reliable, but as a single test it may be too time-consuming to use although this depends on how rapidly the diagnosis must be confirmed. In conclusion, this study showed the PCR to be superior in detecting LSD virus from blood and skin samples. However, virus isolation is still required when the infectivity of the LSD virus is to be determined. Indexed by Sabinet Online
