[Coincidence of congenital infiltrative facial lipoma and lingual myxoma in a newborn Holstein calf]

A one-day-old male Holstein calf was presented with a palpable subcutaneous mass, extending from the parotid to the orbital region, involving the entire right side of the face and a large flabby mass without any evidence of inflammation or edema on the tongue. Macroscopically, the cut surface of the lingual mass appeared slightly lobulated, pink, with a mucoid appearance and gelatinous consistency. Histopathological examination confirmed the infiltrative subcutaneous lipoma and lingual myxoma

evidenced by low cellularity and abundant basophilic, mucinous stroma. In this report, clinical and detailed histhopathological findings of congenital infiltrative myxoma and its coincidence with infiltrative facial lipoma is reported in a newborn calf.

[ relationship between vitamin A and zinc in plasma and liver of cattle]

Numerous abnormalities and clinical syndromes have been associated with vitamin A and zinc deficiency in large animals. In addition, zinc status influences several aspects of vitamin A metabolism including its mobilization from liver to other tissues. The purpose of the present study is to determine the vitamin A and zinc status and their relationship in cattle. Vitamin A and zinc concentrations in blood plasma and liver samples of 114 to 130 male slaughtered cattle [under 18 months old] in Urmia were assessed and their status and correlations were analyzed. In 15.6, 25.4, 5.4 and 3.8% of samples, the concentrations of vitamin A and zinc in plasma and liver were less than minimum recommended concentration, respectively. In 24.8% of samples vitamin A in liver was more than maximum recommended concentration. The mean concentrations [ +/- standard error] of vitamin A and zinc in plasma and vitamin A and zinc in liver were 59.7 +/- 4.5 microg/dL, 99.1 +/- 4.7 microg/dL, 161.9 +/- 6.2 microg/g wet weight and 103.2 +/- 4.7 microg/g wet weight, respectively. In cattle with zinc levels lower than minimum reference value, vitamin A in plasma and zinc concentration in liver were significantly [p<0.0005] less than those of cattle with normal plasma zinc levels. In cattle with inadequate zinc status a direct significant correlation [p<0.01, r=0.481] between plasma and liver vitamin A levels was observed. However, in cattle with adequate zinc status, the plasma zinc had a positive significant correlation with plasma vitamin A [p<0.01, r=0.466], liver vitamin A [p<0.01, r=0.411] and liver zinc [p<0.01, r=372]. Deficiency of vitamin A and zinc are relatively common in Urmia and the deficiency probably leads to subclinical and clinical abnormalities. Furthermore, zinc had significant effects on plasma and liver vitamin A status

[Serum protein alterations in goats naturally infected with Babesia ovis]

This study was conducted to determine the electrophoretic pattern of serum protein in goats infected with Babesia ovis. Serum total protein was calculated and serum electrophoresis from 15 goats naturally infected with B. ovis as well as same number of healthy goats was performed. Microscopic examination of Giemsa-stained peripheral blood smears revealed B. ovis infection. The parasitological diagnosis was confirmed using polymerase chain reaction [PCR] assay by using a pair of B. ovis-specific primers. Mean values total protein and alpha and gama globulin fractions in infected goats were significantly higher [P<0.05] than those observed in the healthy group

Study of epidemiologic measures of association between giardia SP infection with occurrence of diarrhea in calves

This study was carried out to investigate the association between infection to Giardia sp. and occurrence of diarrhea in Urmia, Iran. Fecal samples were collected from 246 calves [34 diarrheic and 212 non-diarrheic] and examined for the presence of Giardia spp. cysts using a quantitative centrifugation concentration zinc sulfate flotation technique. Analysis of data showed that the relative frequency of infection to Giardia cysts is significantly [p < 0.001] more in diarrheic calves [35.3%] than in non-diarrheic ones [8%]. Epidemiologic measures of association, i.e., odds ratio, population odds ratio, attributable risk, attributable fraction, population attributable rate, population attributable fraction were 6.26, 1.42, 31.2, 3.7, and 0.27, respectively. The results would suggest that there is a significant association between infection Giardia spp. and occurrence of diarrhea in Urmia district. However, more studies are required to establish a cause-effect relationship

Induction of general anaesthesia with intraosseous injection of thiopental in rabbits

The technique of intraosseous [IO] infusion has been reemerged as an alternative route of intravascular access for the delivery of fluids and some medications. Complications of IO infusion occur rarely and include fractures and osteomyelitis after long-term use of IO access. The purpose of this study was to compare the efficiency of induction of anaesthesia by a standard intravenous route and an intraosseous route. Ten healthy rabbits were assigned to one of two treatments: thiopental 20 mg/kg administered intravenously via marginal vein of ear and thiopental 20 mg/kg administered intraosseously into the bone marrow of proximal tibia. In each rabbit, the heart and respiratory rates and palpebral, corneal, pinch and withdrawal reflexes were recorded before and every 2 min, for 34 min after induction of anaesthesia. Neither the clinical parameters nor the reflexes showed any significant difference [P>0.05] between the treatment groups. In addition, no adverse reaction was seen in rabbits anaesthetized by intraosseous access. The results of this study showed that the intraosseous injection of thiopental is a rapid, simple, safe and effective alternative option for induction of general anaesthesia in rabbits

Clinical study of lameness associated with digital diseases in dairy cows in Urmia

To determine the prevalence rate of lameness associated with digital diseases. Cross-sectional study. 8 industrial and 30 semi industrial dairy farms. With attending in the farms, lame cows were diagnosed by observation and clinical examination. Lameness was assessed according to the standard scoring method. The affected limb was carefully examined in a chute. The lesion was confirmed through clinical findings and gross pathology. The results were recorded in a self-administered questionnaire. Chi-square test. 195 out of 1871 cases were affected in one or more feet. The prevalence rate of lameness in semi industrial farms was significantly higher than industrial ones. Foot overgrowth was the most important factor as the cause of lameness. Foot rot was seen in sporadic form. The prevalence rate of lameness in the hind limb was significantly higher than forelimb. It seems digital diseases are not prevalent in Urmia dairy farms and mainly occur sporadically. High prevalence rate of lameness in semi industrial farms is due to poor management in hoof trimming

first report of sporotrichosis in horse in around Tehran

In spring 1994 a four year old throughbred horse was examined at a horse club in the vicinity of Tehran. Inflammation of left leg was evident Biopsy puncture and blood samples were taken for histopathological microbilogical haematological and mycological tests. Mycological results showed that sporothrix schenckii is the causative agent and sporothricosis confirmed. Treatment with potassium iodide 10 gram daily via oral route for two months was recommended. However complete recovery did not achieve because the disease was in chronic stage. This is the first report of equine sporothricosis from Iran
