The present study aimed to examine the effectiveness of silymarin compared to hydrocortisone on clinical and hematological alterations and organ injury (liver and heart) in a low-dose canine lipopolysaccharide (LPS)-induced sepsis model. Fifteen clinically healthy dogs were randomly categorized into three equal groups: Two dogs in group A, LPS (0.10 μg kg-1, IV) was injected (control, n = 5); Group B was similar to group A, with the difference that silymarin bolus (10.00 mg kg-1, IV, once) was injected 40 min after LPS injection. Group C was similar to group B with the difference that hydrocortisone bolus (2.00 mg kg-1, IV, once) was administrated instead of silymarin. Five mL of blood was collected at baseline, 1, 3, and 6 hr of the study. Septic control dogs experienced a significant reduction in red blood cells count (RBC), hemoglobin (Hb), and hematocrit (HCT) and a significant elevation in serum activities of aspartate aminotransferase (AST), alkaline phosphatase (ALP), lactate dehydrogenase (LDH), creatine kinase isoenzyme MB (CK-MB), and plasma cardiac troponin I (cTnI) concentration. We noticed a significant increase in RBCs, Hb, and HCT, and a significant decrease in AST, ALP, LDH, CK-MB, and cTnI in the silymarin group in comparison with hydrocortisone and control group. Our results suggested that silymarin had a positive influence on sepsis due to protecting RBCs, and decreasing organ (heart and liver) injury. These findings supported the hypothesis that silymarin could be more effective than routine corticosteroid therapy in sepsis.

The aim of the present study was to compare the effects of hypericin and fluoxetine in the treatment of companion dogs with tail chasing in Ahvaz district. In the present survey, eighteen dogs with tail chasing were assigned into three equal groups for a three-year period. The dogs were randomly classified based on different treatment groups. During 15 weeks, dogs of group A were given 0.05 mg kg-1 hypericin orally and dogs of group B received 1 mg kg-1 fluoxetine, orally. The group C was the control group. Changes in signs of tail chasing were weekly reported by the owners or a veterinarian. Treatment periods were assessed in five intervals: weeks 1-3, 4-6, 7-9, 10-12 and weeks 13-15, respectively. Hypericin (group A) was significantly more effective in the treatment of tail chasing compared with fluoxetine (group B), (p = 0.043). Statistical analysis revealed a significant difference in each group between weeks 1-3 (X2 = 8.8, p = 0.01), 4-6 (X2 = 9.1, p = 0.01), 7-9 (X2 = 7.4, p = 0.03), 10-12 (X2 = 10.4, p = 0.005) and 13-15 (X2 = 12.5, p = 0.002). Improvement of behavior in the dogs of group A was significant compared with group B, between weeks 10-12 (X2 = 5.4, p = 0.02) and 13-15 (X2 = 7.2, p = 0.007). In conclusion, our survey showed that hypericin was more effective than fluoxetine in controlling signs of tail chasing.

Ultrasonographic examination of urinary system (kidney and urinary bladder) was conducted in New Zealand white rabbit [NZwr] and Tolai hare (Lepus tolai). Ultrasound images of the kidney and urinary bladder were evaluated on fifteen healthy rabbits of New Zealand white rabbit and another fifteen Tolai hares. The healthy rabbits were 8-12 months old (mean = 9.3 months), of both sexes and weighed between 1.1-1.7 kg (mean = 1.250 kg). All examinations were performed while the rabbits were in dorsal recumbancy. The kidneys were examined from fossa by the use of an 8 MHz linear real-time scanner. This study revealed the following measurements normal rabbit kidneys: 27.80-35.70 mm and 16.90-22.40 mm in length and width in New Zealand white rabbit, respectively. The length and width were 26.67-34.50 and 15.82-20.60 mm, in Tolai hare, respectively. Bladder wall thickness varies from 1.70-2.50 mm (in New Zealand white rabbit) to 1.80-2.60 mm (in Tolai hare). Statistical analysis showed that the gender did not have effect on length, width and weight (P > 0.05), but the type of the animal, had significant effect on the cortex and surface (P < 0.05). In the present study, the renal cortex was uniform in echogenicity, hyperechoic to the renal medulla, hypoechoic to the spleen, and isoechoic to the hepatic parenchyma.

The present study was conducted to detect prevalence and risk factors for retrovirus infection of infected cats in a cat population in Iran, by evaluation of 238 client-owned cats of different ages that were tested for the presence of FIV antibodies. The cats were selected from those referring to Veterinary Hospital of Ahvaz University, southwestern Iran from December 2007 to June 2010. Classification was made by age, sex, breed, region and season. The studied cats were divided into two age groups (≤ 3 years and >3 years) and based on clinical signs into two groups. Prevalence of FIV antibodies in these cats was 10.5 % by immunochromatography assay, indicating that this virus is present in the environment. The infection had more prevalence in cats above 3 years (13.9 %) compared with cats less than 3 years (4.6 %). Statistical analysis showed significant difference between different age groups. Mean age of FIV-infected and FIV-negative cats were 4.93 ± 0.43 years (range 1.75 – 10 years) and 4.15 ± 0.20 years (range 0.4 – 15 years), respectively. Prevalence of infection was 12.6% in males and 8.1 % in females; nevertheless the infection was not significant between different sexes (P > 0.05). Six out of 36 cases (16.7 %) which had clinical signs and 19 out of 202 cases (9.4 %) which did not have clinical signs were seropositive, without significant difference between two groups (95 % CI for OR = 1.92). Risk factors for FIV infection were older age (95 % CI for OR = 3.35), access to outdoor (95 % CI for OR = 140.9) and aggressive behavior (95 % CI for OR = 82.71).
