The Iraqi Journal of Veterinary Medicine (IJVM), 2007, Volume 31, Issue 2, Pages 1-14

397 fecal samples were collected from dogs of different breeds, ages and sex. Detection of rotavirus was achieved by two techniques latex agglutination test and agar gel diffusion test. Blood samples were collected to study various hematological parameters.
The results showed that 95 samples were positive to rotavirus 23 samples (24.2%) were from diarrheic cases and 72 samples (75.8%) were from non diarrheic cases.
Younger dogs were more affected with rotavirus infection 17 positive cases than older ages 6 positive cases. The results showed that diarrheic cases caused by rotavirus were 23 cases (25.3%) that were less than the diarrheic cases caused by other agents 68 cases (74.7%).
It had been shown that the ages less than one year (11 cases) were more affected with rotavirus and complication with dehydration than ages older than one year (2 cases).
It was found that the morbidity rate in males (53%) was significantly higher than females (47%).
The Terrier breed showed a high morbidity rate 42% than others Mixed, Greatdane, Goledretriver and Doberman.
Our study showed that latex agglutination test was more sensitive than agar gel diffusion test and the positive samples out of 200 samples were detected by using latex agglutination test were 39 samples while 18 positive samples by agar gel diffusion test.
There were no differences in blood parameters of the dogs that showed positive results of rotavirus in comparing them with the negative results.
The study showed that rotavirus is widely spreaded among doges with gastrointestinal diseases, it showed that latex agglutination test is more reliable for quick clinical diagnosis.

The objective of this study was investigate the Physiological effect of different concentrations of cadmium chloride in drinking water on some biochemical and haematological parameters of male rats. Animals in this experiment were randomly divided into four equal groups and treated for 15 weeks as follows : Rats in control group were offered ordinary tap water , while animal in M1 , M2 , and M3 were received 10 , 20 , 30 ppm Cdcl2 in drinking water, respectively. The activity of Alanine aminotransferase (ALP), Aspartate aminotrasferase (AST) and alkaline phosphatase (ALP) in serum were measured. Further mor, hemoglobin concentration (Hb) and white blood cells count (WBCs) were detected. The result revealed that addition of cadmium chloride in different concentrations in drinking water caused a significant increase in activity of serum of ALT in treated group (M1 , M2 , M3 ) as compound with control. Within the time the activity of serum AST was significantly increased in three treated group as compared with pretreatment period. On the other hand , significant increase in serum ALP concentration were show in both M1 and M3 treated groups at 12th and 15th week of the treatment as compared with control group. Significant decrease in haemoglobin concentration were observed in M1 , M2 , M3 from 9th week to the end of experiment comparing to control. While cadmium chloride treatment caused significant increase in total white blood cells count in treated groups as compared with control group. On Conclusion, it seems likely that exposure of male rats to cadmium chloride at level above the permissive one had induced clear biochemical and haematological changes.

To induce copper deficiency in sheep (15)Awasi ewes from the college of Veterinary Medicine flock were used. The ewes during the preparation period (18 weeks) were fed on balanced concentrated diet contained (5.2) mg/day copper in addition of the green food.
The ewes were randomly divided into three equal groups for the experimental period (18 weeks). Another balanced concentrated diet with low level of copper (2.6) mg/day was used to feed the primary deficiency group while the secondary copper deficiency group fed on the same concentrate used in the preparation period. The protein ratio and energy level were considered.
The secondary deficiency group received an oral mixture of ammonium molybdate (100) mg with (1) g of sodium sulphate in (100) ml of water daily.
One ewe and two lambs died from the primary deficiency group however a dead still born lamb was born from the secondary deficiency group. The postmortem examination of dead animals studies was done and histopathological samples from the central nervous system, heart, lung, kidney and muscles were examined.
The histopathological examination showed vaculation, degeneration with demylination in central nervous system. These changes were more sever in lumber and thoracic than cervical spinal cord. The same changes were found in the cerebrum and cerebellum. While the liver, heart, lung, kidney showed hydropic degeneration and cloudy swelling. The symptoms and changes through the experimental period were more obvious in the secondary deficiency group than in the primary one.

Thirty two mice were used to study the histopathological changes resulted from the effect of vitamin C on the some mice tissues treated with nitrate.
Mice were divided randomly in to four equal groups. The 1st group was given Vit C and potassium nitrate via water. The 2nd group was given potassium nitrate and the 3rd group received Vit C only, while the 4th group represented the control.
Two animals from each group were scarified weekly. The results showed similar pathological changes in the 1st and 2nd group especially in the stomach and intestine which gave severe changes that characterized by hyperplastic changes in addition for the hemorrhages and the infiltrations of inflammatory cells in all layers of both organs. Less alteration was seen in the liver and kidney. On the other hand, no pathological changes in the 3rd and 4th group were recorded.
