Hussein A. Abdul Wahid | Kamal M. AL-Saad
Bovine viral diarrhea BVD has been detected and diagnosed in local buffalocalve breeds of Basrah, Iraq. The study was conducted to examine (980) suspectedbuffalo calves under one year old and of both sexes. One hundred sixty-eight(168)calves give positive results with PCR test. Twenty-five (25) clinical healthylocal buffalo calves are considered as controls. Diseased calves show different clinicalmanifestations belong to the disease with a significant increase indicated in the bodytemperature, respiratory and heart rate, as well as the capillary refill time of diseasedbuffalo calve compared with controls. Results of hematological changes indicated asignificant increase in packed cell volume in diseased buffalo calve than in controls,Moreover, A significant leukocytopenia due to a significant lymphocytopenia wasalso indicated in diseased animals compared with the control group. Results of theclotting factor indices of diseased calves and controls show a significant decrease intotal platelet counts, However, the platelet volume and the platelet distribution width,the clotting time, the prothrombin time, the activated partial thromboplastin time wassignificantly increased in infected animals than in controls. A significant high valuewas indicated in Aspartate and Alanine aminotransferase, Alkaline phosphatize aswell as the blood urea nitrogen, In BVD buffalo animals than in the control animals,On the contrary, a significant decrease was encountered in total protein in diseasedcalves than in the control group. Results of the acute phase response of the currentstudy revealed a significant increase in haptoglobin in BVD buffalo calves than thecontrol group, Whereas, a significant decrease in Fibrinogen time has been indicatedin BVD calves. The macroscopic examinations of the BVD carcasses revealed severecongestion of the intestinal vessels accompanied by Ecchymotic hemorrhagic enteritiswith multiple enlargements of mesenteric lymph nodes along with most parts of thesmall and large intestine with pasty fecal materials. Furthermore, atrophy of theintestinal villi with sloughing of the epithelial lining of villi of the small intestine, aswell to hyperplasia of goblet cells, infiltration of inflammatory cells in the intestinalmucosa, to congestion of blood vessels was also indicated via histopathologicalexaminations. It has been concluded that BVD has very harmful effects on domesticruminants, which mostly terminated by death, Therefore, applying the controlmeasures is the final and suitable choice to control and eliminate the disease.

The blood is a connective tissue that composes of suspended cells in liquidmatrix. In this study ,we discuss the effect of three factors on blood sampling duringthe collection of blood samples (anti-coagulants, temperature and duration of storage). The delay of storage processing led to hemolysis of blood sample , increase ofhemoglobin, decrease of red cells ,triglycerides, hematocrite, mean corpuscularvolume, mean corpuscular hemoglobin and its concentration and increase number ofwhite blood cells. The histological analysis of blood sample during long-term storageshowed a slight difference in the shape and size of RBC,WBC and platelets as well ascondensed nucleus bluish cytoplasm and basophilic segmented nucleus in neutrophilsin addition to decrease in sodium ,calcium and chloride. The effect of temperature onblood sampling showed slight variation in shape and size of RBC , basophilicneutrophils and platelets aggregation and decrease of leukocyte number and K levels .

Babesia bigemina is considered as one of the most remarkable blood protozoa in cattleand mainly transmitted via arthropod. This study was conducted on a random group of cows,they numbered 180 local cows who ranged in age from 3-7 years old, from different localities inMosul city north Iraq, comprising both clinically healthy (n=162) and clinically suspectedinfected animals (n= 18). In this study, indirect-enzyme immunosorbent Assay (I-ELISA) wasused to detect of babesia antibodies known as B. bigemina in the blood serum. Then, the bloodand biochemical information that existed from both groups was analyzed, so that the two of themare compared with the control group (n=15). The result showed that the overall seroprevalence ofB. bigemina in cows was 74/180 (41.1%) for clinical and subclinical cows were 10% and 31.1%respectively. The subclinical infected cows was statistically higher than that of clinically infected(P<0.05). Clinically infected cows were suffering from acute onset of the disease includes fever,anorexia, emaciation, drooping in milk yield, jaundice and hemoglobinuria,, with significanthematological and biochemical parameters alterations. While, subclinically infection cowsappeared healthy with absence of changes in blood and biochemistry tests as compared to controlgroups. It has been concluded that significant cases were diagnosed suffering from acuteinfection with the B. bigemina with higher prevalence of subclinical cases in Mosul city, Iraq.

OBJECTIVE To determine the effects of coadministration of naltrexone, a human opioid abuse deterrent, on the pharmacokinetics and pharmacodynamics of a methadone-fluconazole combination administered orally to dogs. Animals: 12 healthy Beagles. PROCEDURES Dogs (body weight, 10.7 to 13.9 kg) were randomly allocated to 2 groups in a parallel design study. All dogs received fluconazole (100 mg [7.19 to 9.35 mg/kg], PO). Twelve hours later (time 0), dogs were administered methadone (10 mg [0.72 to 0.93 mg/kg]) plus fluconazole (50 mg [3.62 to 4.22 mg/kg]; methadone-fluconazole) or methadone (10 mg [0.72 to 0.93 mg/kg]) plus fluconazole (50 mg [3.60 to 4.67 mg/kg]) and naltrexone (2.5 mg [0.18 to 0.23 mg/kg]; methadone-fluconazole-naltrexone), PO, in a gelatin capsule. Blood samples were collected for pharmacokinetic analysis, and rectal temperature and sedation were assessed to evaluate opioid effects at predetermined times up to 24 hours after treatment. RESULTS Most dogs had slight sedation during the 12 hours after drug administration; 1 dog/group had moderate sedation at 1 time point. Mean rectal temperatures decreased significantly from baseline (immediate pretreatment) values from 2 to ≥ 12 hours and 2 to ≥ 8 hours after methadone-fluconazole and methadone-fluconazole-naltrexone treatment, respectively. Geometric mean maximum observed concentration of methadone in plasma was 35.1 and 33.5 ng/mL and geometric mean terminal half-life was 7.92 and 7.09 hours after methadone-fluconazole and methadone-fluconazole-naltrexone treatment, respectively. Naltrexone was sporadically detected in 1 dog. The active naltrexone metabolite, β-naltrexol, was not detected. The inactive metabolite, naltrexone glucuronide, was detected in all dogs administered methadone-fluconazole-naltrexone. CONCLUSIONS AND CLINICAL RELEVANCE Opioid effects were detected after oral administration of methadone-fluconazole or methadone-fluconazole-naltrexone. Further studies assessing additional opioid effects, including antinociception, are needed.

The objective of this study was to evaluate the effect of intra-abdominal pressure (IAP) on cardiorespiratory parameters during pneumoperitoneum with carbon dioxide in domestic rabbits. Six juvenile female New Zealand white rabbits were assigned to randomized sequences of IAP (0, 4, 8 mmHg) in a crossover study. The following parameters were measured at each IAP: direct arterial blood pressure (ABP); cardiac output, (CO), cardiac index, and stroke volume index (CI, SVI); heart rate; end-tidal carbon dioxide (ETCO(2)); arterial blood gases (PaCO(2), PaO(2)); peak inspiratory pressure (PIP); and peripheral oxygen saturation (SpO(2)). Between IAPs, the abdomen was desufflated for a 5-minute washout period. Mixed linear regression models were used for statistical analysis. Heart rate, SpO(2), and ABP were not significantly affected by IAP, although there was a positive increase in ABP with IAP. Partial pressure of carbon dioxide (PaCO(2)) was increased at an IAP of 8 mmHg and ETCO(2) and PIP were greater with each IAP applied. Cardiac output and CI were significantly decreased with IAP and, although SVI showed the same trend, it was not statistically significant. In conclusion, pneumoperitoneum with carbon dioxide causes an increase in ETCO(2), PaCO(2), and PIP, whereas cardiac output and CI decrease. These cardiorespiratory changes should be considered when determining the optimal IAP for laparoscopic procedures in rabbits.

OBJECTIVE To evaluate the effect of presurgical storage conditions on leakage pressures of enterotomy sites closed with unidirectional barbed suture material in fresh, chilled, and frozen-thawed cadaveric canine jejunal specimens. SAMPLE 36 grossly normal jejunal segments obtained from 4 dog cadavers. PROCEDURES 9 jejunal segments were harvested immediately from each euthanized dog and randomly assigned to be tested within 4 hours after collection (fresh segments), stored at 4°C for 24 hours before testing (chilled segments), or stored at −20°C for 7 days and thawed at 21°C for 6 hours before testing (frozen-thawed segments). For leakage pressure testing, a 3-cm-long antimesenteric enterotomy was performed and repaired with 3-0 unidirectional barbed suture material in a simple continuous pattern in each segment. Time to complete the enterotomy, initial leakage pressure, maximum intraluminal pressure, and leakage location were recorded for each segment. RESULTS Mean ± SD initial leakage pressure for fresh, chilled, and frozen-thawed segments was 52.8 ± 14.9 mm Hg, 51.8 ± 11.9 mm Hg, and 33.3 ± 7.7 mm Hg, respectively. Frozen-thawed segments had significantly lower mean initial leakage pressure, compared with findings for fresh or chilled segments. Time to complete the enterotomy, maximum intraluminal pressure, and leakage location did not differ among groups. CONCLUSIONS AND CLINICAL RELEVANCE Leak pressure testing of cadaveric jejunal segments that are fresh or chilled at 4°C for 24 hours is recommended for enterotomy studies involving barbed suture material in dogs. Freezing and thawing of cadaveric jejunal tissues prior to investigative use is not recommended because leak pressure data may be falsely low.
