Objective: Metacarpophalangeal joint (MCPJ) radiographic parameters were developed to evaluate MCPJ conformation of equine forelimbs, but the effect of joint rotation during radiography on these parameters has not been reported. The current study examined the effect of the rotation around the vertical axis of MCPJ on 27 MCPJ parameters (12 angles and 15 ratios) and identified the acceptable range of rotation at which minimal amount of changes occurred in these parameters. Design: Descriptive study Animals: MCPJs of seven right forelimbs from seven different horses with no MCPJ abnormalities. Procedures: MCPJs of seven right equine forelimbs were loaded in a load cell to obtain the normal MCPJ angle. They were frozen at −20C° and then scanned using a CT-scan machine. The collected slices were reconstructed to obtain a 3D model of MCPJs, and the dorsopalmar view at zero angle (ZDP) were identified. The view was then rotated around the vertical axis of MCPJ. Snapshots were taken for MCPJ at −10°, −5°, Zero, +5° and +10° angles. All the parameters were measured on the total 35 radiographs and statistically analysed. Differences were estimated per 5° of MCPJ rotation for all the parameters. Results:Generally, the ratio parameters were less affected than the angular parameters during MCPJ rotation. Conclusion and clinical relevance: Rotational angles of vertical ±10° from ZDP were considered as an acceptable range for reliable radiographic measurements of MCPJ parameters.

Formaldehyde is an anxious gas used as a tissue preservative of cadavers in anatomy halls. Therefore, laboratory staff and students are at high risk of different clinical complications due to the continuous exposure to formaldehyde. The present questionnaire-based study evaluates the effects of formaldehyde exposure on veterinary students and staff in the anatomy gross dissection laboratory, University of Tripoli, Libya. A total of 104 students and 6 anatomy staff members completed a questionnaire of 24 questions related to the clinical symptoms observed after formaldehyde exposure and the answers were assessed using a six point (0-5) scale. Students had a high prevalence of nasal itching 78(75%), eyes burning 78(75%), excessive lacrimation 76(73%), eyes redness 60(58%), headache 64(62%) and respiratory distress 61(59%). Smoking and wearing glasses or gloves worsened many symptoms while wearing masks minimized other symptoms and male students were more affected than females. All anatomy staff members (100%) reported nasal itching, burning and congestion, eyes burning and redness, excessive lacrimation, cough and respiratory distress and less than that (83%) suffered from mouth dryness, headache, temporary loss of their ability to recognize the smell of formaldehyde and needed a physician assistance after the exposure to formaldehyde. The repeated exposure to formaldehyde in gross anatomy dissection has harmful effects on both students and staff member and finding alternative preservation methods, such as freezing, would be safer than using the formaldehyde. arabic 12 English 74

As little is known about the blood profile of camels in Libya, this article is the first of a 4-part series describing the biochemical and haematological blood profile in Libyan camels. Part 1 of these manuscripts determines the values of enzymes, metabolites, electrolytes and haematological indices in the blood of Libyan camels, parts 2-4 evaluates the effects of breed, gender and age respectively on these values. In this study, blood samples were collected from sixty six camels of three different breeds, different ages and with both sex. The blood of the studied camels showed (i) average values of Potassium (K), Calcium (Ca), Magnesium (Mg), Phosphorus (Ph), Haemoglobin (Hb), Packed Cell Volume (PCV) and White Blood Cell (WBC) counts (ii) low values of Sodium (Na), Iron (Fe), total proteins, albumin, globulin, creatinine, cholesterol, triglycerides, Mean Corpuscular Volume (MCV), Mean Corpuscular Haemoglobin (MCH), and low serum activity of aspartate aminotransferase (AST), alanine aminotransferase (ALT), lactate dehydrogenase (LDH), alkaline phosphatase (ALP), gamma glutamyl transferase (GGT) and amylase (AMS) enzymes and (iii) high values of glucose, urea, Red Blood Cell (RBC) counts, Erythrocyte Sedimentation Rate (ESR) and Mean Corpuscular Haemoglobin Concentration (MCHC). The finding of this study was documented and compared with the findings of similar studies performed elsewhere. arabic 25 English 134
