Twenty domestic shorthair cats apart from weight, age and gender differences after clinical examination were studied in lateral and ventrodorsal projections with both computed and analog radiography. Then, three radiologists independently evaluated the radiographs. Histopathology investigation used as gold standard to confirm the interstitial lung pattern detected on the radiographs. Statistical data of two radiologic approaches were analyzed by Cohen’s Kappa test and the sensitivity and specificity of each approach were also calculated. The agreement for the interstitial lung pattern was fair for both systems, but computed radiography was more sensitive. In current study the ability of computed radiography was equivalent or superior to conventional radiography for evaluation of interstitial lung pattern, since displaying more radiographic details. Accordingly, it can be a proper substitute for analog radiography considering its advantages including elimination of dark room, high contrast resolution and wide dynamic range. Manuscript profile -

Hemimelia is a congenital complete or partial absence of one or more than one bone in limbs. All appendicular bones can be affected and many variations have been shown. Radial, tibial and ulnar hemimielia are usually common. In the present clinical report we found terminal hemimelia in the left hind limb along with agenesis of tibia, metatarsal bones and phalanges and agenesis of metatarsal bones and phalanges in the contralateral hindlimb. In treatment of tibial hemimelia, it may be possible to prevent permanent muscle contraction, bone deformation and varus but in this case, amputation of affected limb was recommended to the owner because of severe limb deformities, limb rotation and impossibility of arthrodesis. Castration/neutering to prevent congenital spread and radiography of other body parts to detect concurrent disorders is recommended in these cases. Manuscript profile -

The purpose of the present research was to evaluate the effects of diphenoxylate and loperamide on the transit time of contrast media from the gastrointestinal in cat. The study was performed on twenty healthy female cat. The cats were divided into four equal groups. The first group (control) was received ketamine with diazepam, 40 min before administration of the contrast media. The second group was received diphenoxylate 0.1 mg/kg, the third group loperamide 0.1 mg/kg, and the fourth group loperamide 0.2 mg/kg, 30 min before administration of contrast media. Tranquilizer drugs were administered to all groups. Then the radiography was performed at times zero, 20, 40 and 60 min, and every hour until reaching the contrast media to colon. All groups that were received drug had a significant difference at the beginning of emptying with control group (p < 0.05). The mean total transit time of the stomach was 52 min for the control group, the diphenoxylate 120, the loperamide 0.1 mg/kg 156 and for the loperamide 0.2 mg/kg 204 min respectively. There was a significant difference between the control and the drug-receiving groups as well as the two groups of diphenoxylate and loperamide 0.2 mg/kg at the time of complete stomach emptying (p < 0.05). In conclusion, it was showed that Loperamide with dosage 0.2 mg/kg had the most delay effect in emptying of the gastrointestinal tract in cat. Manuscript profile -

Prompt diagnosis of the disease is very important as it may lead to fatality in undetected and untreated cases. This study was carried out to investigate and identify the echocardiographic and radiographic indicators of dogs with DCM by sex, sterility status, breed, age and weight. For this purpose, using echocardiography and radiography, various parameters of the left ventricle and VHS (Vertebrae Heart Scale) of all dogs with DCM were measured. The results showed that the highest rate of prevalence was related to unsterilized male terrier dogs with the age of 6-9 years and body weight of 5-10 kg. The echocardiographic findings showed that there were significant differences in different ages (p=0.05) between the parameters of IVSs (Intraventricular Septum at end Systole) and LVDs (Left Ventricular Internal Diameter at end Systole) in male and female DCM dogs, EF (Ejection Fraction) and FS (Fractional Shortening) of different sterility status, LVD (Left Ventricular Internal Diameter) and RVD (Right Ventricular Internal Diameter) of different breeds, all parameters measured in different weights and EF, LVDd (Left Ventricular Internal Diameter at end Diastole) and LVDs. The average VHS of dogs with breed, age, sterility status and different weights with DCM were significantly different from each other (p=0.04, p=0.04 and p=0.01). But, the findings showed that gender had no effect on VHS change. It seems that detection of the canine population with DCM disease according to related diagnostic imaging findings can help in the early diagnosis of this disease. Moreover, the findings of this research can be considered as a valid reference in the examination of different dogs with DCM. Manuscript profile -

There are very few papers in forensic literature in which scapular dimensions have been used for estimation of human height. This study aimed to evaluate the correlation of human height and weight with scapula length in normal chest radiography. Methods: This cross-sectional study was carried out on patients who refer to radiology clinic of Aria and 22-bahman for chest radiography hospital in Mashhad, Iran in 2012-2013. In this study, we recorded patient height, weight and age, then measure scapula length based on chest X ray. The tool of gathering the data was a questionnaire asking about age and sex, also height, weight and scapula length were mention in this questionnaire. Findings: a total of 100 patients (50 women and 50 men), participated in the study. The average of age, height and weight were 49.5, 164.3 cm and 71kg, respectively. There was a significant difference between height and scapula length (P-Value=0.0001**). Also, there was a significant difference between weight and scapula length (P-Value=0.0001**). Conclusion: In general, results show that there is a significant difference between height, weight and scapula length (P-Value<0.05). Due to this fact, in forensic practice, we can estimate human height based on scapula sample. Manuscript profile -

Five healthy, non-pregnant milkier Holstein cows were selected and after preoperative considerations, the rear teats were prepared for aseptic surgery. The left teats (1/3 of distal portion) were amputated horizontally, and fullthickness elliptical incisions were induced in 1/3 of proximal of the right teats from the base, in medial aspect. Anastomosis between amputated and neighboring teats was completed with two rows of sutures, simple interrupted in mucosal layer and interrupted horizontal mattress in intermediate and skin layers with polyglactin910(Coated Vicryl),sized 3-0 and 2-0,respectively. Radiographs with meglumine compound (positive contrast media) were prepared under condition of FFD = 80 Cm, 50 Kv, 20 mAs from all anastomised teats with and without positive pressure in 3 day before surgery and 4, 15, 30 and 44 days after the operation. According to radiographic results inner diameter of anastomosis junction were measured 14-20 mm under positive pressure and 11-16 mm without positive pressure in 44th day after the operation. According to the good radiographic findings and simplicity of this surgical technique, Teat anastomosis can be recommend for the treatment of sever teat injuries in dairy cows. Manuscript profile
