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

Abstract As little is known about the blood profile of camels in libya, this article is the second of a 4-part series describing the biochemical and haematological blood profile in Libyan camels. In Part 1 of these manuscripts, the overall blood biochemical and haematological mean values of camels in Libya were determined, parts 2-4 evaluates the effects of breed, gender and age respectively on these values. Blood samples were collected from three camel breeds, namely, Fakhreya, Sirtaweya and Mahari, and the levels of enzymes, metabolites, electrolytes and haematological indices were measured. The blood of the Sirtaweya breed showed (i) higher levels of aspartate aminotransferase (AST), albumin and Phosphorus (Ph), than the other two breeds, (ii) higher levels of lactate dehydrogenase (LDH), amylase (AMS) and total proteins than the Fakhreya breed and (iii) higher levels of glucose, triglycerides, total cholesterol, Very Low Density Lipoprotein (VLDL), Low Density Lipoprotein (LDL), Calcium (Ca), Packed Cell volume (PCV), Mean Corpuscular Volume (MCV) and Albumin/Globulin (A/G) ratio than the Mahari breed. The Fakhreya breed had (i) higher levels of urea, Iron (Fe), Haemoglobin (Hb), Mean Corpuscular Haemoglobin (MCH) and neutrophils number than the other two breeds, (ii) higher levels of glucose, A/G, LDL, Ca, PCV, MCV and monocytes number than the Mahari breed and (iii) higher levels of erythrocyte osmotic fragility, MCH and Mean Corpuscular Hemoglobin Concentration (MCHC) than the Sirtaweya breed. The Mahari breed had (i) higher levels of globulin than the other two breeds, (ii) higher levels of AMS than the Fakhreya breed and (iii) higher levels of erythrocyte osmotic fragility, Erythrocyte Sedimentation Rate (ESR), MCHC than the Sirtaweya breed. The tested blood parameters in the three Libyan breeds in this study were affected by breed variations. arabic 28 English 143

As little is known about the blood profile of camels in Libya, this article is the third of a 4-part series describing the biochemical and haematological blood profile in Libyan camels. In part 1 of these manuscripts, the overall blood biochemical and haematological mean values of camels in Libya were determined, parts 2-4 evaluate the effects of breed, gender and age respectively on these values. Blood samples were collected from 24 male and 42 female apparently healthy camels and the levels of enzymes, metabolites, electrolytes and haematological indices were measured. The blood of the male camels showed higher values of aspartate aminotransferase (AST), Lactate dehydrogenase (LDH), Amylase (AMS), total proteins, globulin and Phosphorus (Ph), than the female camels which showed higher values of glucose, Albumin/Globulin (A/G) ratio, urea, Iron (Fe), Calcium (Ca), Packed Cell volume (PCV), Haemoglobin (Hb), erythrocyte osmotic fragility, Mean Corpuscular Volume (MCV), Mean Corpuscular Haemoglobin (MCH), neutrophil and monocyte numbers. This study shows significant sex differences between male and female Libyan camels in many haematological and biochemical analytes. arabic 28 English 141

The forelimb fetlock joint and its bony components are a common site of injury in racing horses. We hypothesized that the variations in relative density of these bones might correspond to their mechanical properties. This study aimed first to identify the relative density of third metacarpal bone (Mc3), proximal phalanx (P1) and proximal sesamoid bones (PSBs) of Thoroughbred race horses. Second, to determine whether there was any difference and/or similarity in the relative density between and within the bones. Bones from right and left forelimbs of 10 horses were collected and prepared by boiling and drying. Dry weight and volume for each bone were measured and the relative density was then calculated. Relative density of Mc3 was substantially greater than the other two bones with a mean of 1.7 ± 0.06. Relative density of P1 and PSBs showed a high similarity especially between P1 and the medial PSBs. Neither the comparisons between right and left sides nor between lateral and medial PSBs showed any significant differences. P1 had the most consistent relative density within right and left sides. Larger relative density in Mc3 and the similarity between P1 and PSBs presume a more important role of the bone mass on their properties than the volume.

Carpal conformation is thought to contribute to the frequency of carpal pathology so non-invasive measurement of carpal morphometry would be useful to identify joints at risk. However, there are scant radiographic morphometrical details for the carpals of Thoroughbred (TB) and Standardbred (SB) racehorses even though these breeds differ in the incidence of carpal damage. This study aimed to identify morphometrical similarities and differences in carpal conformation in TB and SB. Thirty carpal dorsopalmar radiographs (DP) were collected from 15 TB and 15 SB. All DP radiographs were at zero degrees or within the acceptable range of rotation. Twelve carpal radiographic parameters were selected and measured on each radiograph. Statistical analysis found significant differences in four carpal parameters. These parameters revealed that the middle carpal joint in SB was significantly more angled distomedially whereas the radial distal metaphysis showed a greater distolateral inclination in TB. The radiocarpal and the carpometacarpal articulations exhibited common features in the two groups of horses. These carpal traits in TB and SB highlight their potential association with loading distribution and pathology. Measuring carpi from untrained and injured horses is necessary to establish breed specific features for the ideal carpal conformation in each of these breeds.

Background: Although bone tumors are common pathologies in companion animals, limited reports describe nasal osteosarcoma (OSA) in cats. Case description: A case of nasal OSA in a local Libyan cat was admitted to the Veterinary Teaching Hospital at the Faculty of Veterinary Medicine, University of Tripoli-Libya, with nasal swelling and discharges and facial deformity. The radiological findings revealed nasal osteolysis with the absence of evidence of lung metastasis. In addition, fungal growth was not identified in microbiological culture. Furthermore, the pathological examination has grossly revealed a destructed nasal bone due to the presence of a tumor mass, with a mucohemorrhagic nasal discharge and absence of metastasis. OSA was confirmed histopathologically. Conclusion: This report presents the clinical, radiological, and pathological findings of a primary nasal OSA in a Libyan cat with no tumor metastasis to other body organs.

Several reports have discussed possible bony morphological causes of fetlock pathology but without relating them to its morphometry. Radiographic measurement is widely used in constructing numerical databases of bone morphometry. Such measurements would not be reliable unless all factors affecting the radiographs were considered. Therefore, this study aimed to establish a specific dorsopalmar view (DP) for fetlock radiographic measurements, and then to develop reliable and repeatable fetlock parameters that represent fetlock conformation on those DP radiographs. Ten cadaveric forelimbs from ten adult horses were cut at the distal third of the radius and mounted in a normal posture for DP radiography. Specific features on fetlock bones were used as landmarks to identify the DP at zero degrees. Other bony features were selected as landmarks for developing fetlock parameters on these radiographs. Twenty-seven parameters were designed in the form of angles (12) and ratios (15). The repeatability and consistency of each parameter was tested. A specific fetlock DP view was determined at zero degrees based on certain landmarks. All angular and ratio parameters showed high reliability and consistency in their measurements. The established parameters provide an opportunity to test the relationship between fetlock morphometrics and performance, or the likelihood of certain pathologies.
