Relationships between carpal morphology and carpal pathology might assist in identifying horses at risk of carpal pathology. This study was aimed to investigate the hypothesis that carpal morphology is related to the incidence of carpal pathology in racing Thoroughbreds. Ten carpal parameters were used to measure carpal morphology on dorsopalmar (DP) carpal radiographs. Radiographs were collected from 19 experienced Thoroughbred race horses with no evidence of carpal damage(normal)and 72 horses with carpal damage (clinical). All radiographs were at a defined position called zero degrees (ZDP) or within an acceptable rotational range. Based on a P-value of < 0.05 and using the false discovery rate method to control Type I error, two parameters showed significant differences between normal and clinical horses. The angulation of the radial metaphysis and distal radius in relation to the angulation of the radial facet of the third carpal bone (C3) was significantly related to the occurrence of pathology in the bones of the middle carpal joint in Thoroughbred race horses. This study presented important features on DP radiographs that allowed identification of a carpal conformation associated with carpal damage in Thoroughbred race horses. Using such a highly specific, cost-effective and safe technique as a routine for examining yearling Thoroughbreds would assist in identifying horses with carpal conformation unsuited to racing.

تم إجراء هذه الدراسة بمنطقة الزاوية و التي تبعد 60 كم غرب مدينة طرابلس في مزارع خاصة للأغنام. أجريت الدراسة في الفترة الزمنية من شهر ناصر(يونيو) 2008 إلي شهر هانيبال (أغسطس) 2009. لقد كانت أهداف هذه الدراسة, البحث و التقصي عن موسمية التناسل و تقييم فعالية عدد من المعالجات الهرمونية في إحداث الشبق و توحيده لتحسين الأداء التناسلي للنعاج البربري الليبية. ولتحقيق هذه الأهداف, تم تنفيذ أربع تجارب مستخدمين فيها 475 نعجة بربري ليبية سليمة و خصبة إضافة إلي عشر كباش سليمة وخصبة من نفس السلالة. التجربة الأولى: تم استخدام 300 نعجة لدراسة عن الموسمية التناسلية لهذه النعاج باستخدام البروستاجلاندين α2F (PGF2α ). قسمت الحيوانات إلي أربع مجاميع و حسب فصول السنة (100, 55, 100و 45 نعجة) للصيف, الخريف, الشتاء و الربيع على التوالي, تم تقسيم كل مجموعة من هذه المجاميع إلي مجموعتين (مجموعة المعالجة و مجموعة المراقبة), تم حقن مجموعة المعالجة بجرعتين (125ميكروجرام( من PGF2α بالعضل بفاصل 11 يوما بين الجرعة الأولى و الثانية. بينما تم حقن مجموعة المراقبة 1 مليلتر بالعضل من المحلول الفسيولوجي (NaCl 0.9) بجرعتين بفاصل 11 يوما بينهما. عند الانتهاء من حقن الجرعة الثانية في كلتا المجموعتين, تم إدخال الكباش للتلقيح الطبيعي لمدة ستة أيام. كانت الفترة الزمنية لظهور علامات الشبق بعد الانتهاء من المعالجة (الجرعة الثانية) مختلفة معنويا جدا (P

Objective: To evaluate the load redistribution mechanisms in walking and trotting dogs with induced forelimb lameness. Animals: 7 healthy adult Beagles. Procedures: Dogs walked and trotted on an instrumented treadmill to determine control values for peak and mean vertical force as well as vertical impulse for all 4 limbs. A small sphere was attached to the ventral pad of the right forelimb paw to induce a reversible lameness, and recordings were repeated for both gaits. Additionally, footfall patterns were assessed to test for changes in temporal gait variables. Results: During walking and trotting, peak and mean vertical force as well as vertical impulse were decreased in the ipsilateral forelimb, increased in the contralateral hind limb, and remained unchanged in the ipsilateral hind limb after lameness was induced. All 3 variables were increased in the contralateral forelimb during trotting, whereas only mean vertical force and vertical impulse were increased during walking. Stance phase duration increased in the contralateral forelimb and hind limb during walking but not during trotting. Conclusions and clinical relevance: Analysis of the results suggested that compensatory load redistribution mechanisms in dogs depend on the gait. All 4 limbs should be evaluated in basic research and clinical studies to determine the effects of lameness on the entire body. Further studies are necessary to elucidate specific mechanisms for unloading of the affected limb and to determine the long-term effects of load changes in animals with chronic lameness arabic 10 English 72
