Abstract

The aim of this study is to evaluate the effect of the auto-omental graft on the fracture healing after destruction of the periosteum around the fracture site in rabbits. Eight mature healthy rabbits of local breed were employed to performed transverse fracture in the mid shift of the femoral bone, under general anesthesia and highly aseptic technique, then destruction of the periosteum was done about 1 cm away from each end of the fragments bone. The immobilization by intramedulary pinning, then the animals were divided into two equal group. The control group was left to follow the healing process, while in the treatment group the auto- omental graft was used to cover the fracture site. This graft was taken from the laparotomy of the left side and weekly radiographic examination performed for 10 weeks. The result is revealed that the omental graft play an important role in promote the fracture healing which was evident during the early new bone formation at the end of the second week compare to the control group which the sign of the callus formation was obvious lately at the end of the third week. The nature of the callus formation of the treatment group was limited to the fracture site and quickly cross the fracture site .While in the control group the new bone formation was heavy unlimited and need 8-9 week to bridge the fracture fragments. The omental graft play role in starting the remodeling phase, by decreasing the amount of the callus formation, with the signs of increase of the callus density, and marked of incorporation of the callus formation with the cortical bone

Abstract

In order to study the pathogenesis of the Pasteurella multocida in its natural rout of infection, this study was done to investigate and compare its pathogenesis after intranasal and intraocular infection.Thirty (30) rabbits were divided into three groups, the 1st group (n=12) infected with 240 CFU of Pasteurella multocida intra-nasal, the 2nd (n=12) infected with 240 CFU of P. multocida intra-ocular (eye drop), and the 3rd group (n=6) served as control negative. The animals were sacrificed if they did not die naturally at 24-48hr, 3, 6, 9, 30 day post-infection (p.i.). The results showed dullness of the animals with nasal and ocular discharge and some animals dead at 48hr and 72 hr p.i. (two animals from the 1st group and four animals from the 2nd group). The gross examination of the dead and sacrificed animals showed hemorrhage in the upper respiratory tract with fibrinous pleuropericaditis and emphysematous lung in the 1st group, while the 2nd group showed eye opacity and in some animal’s eye swelling in addition to the feature noticed in the 1st group. Pasteurella multocida was isolated from the organs of all the infected animals.The histopathological changes in the 1st group were more intense than the 2nd group and concenterated at the upper and lower respiratory tract as acute hemorrhagic treacheatis with fibrinous pneumonia , while the kidney showed hypercellularity of the glomeruli with cellular degeneration of renal tubule and lymphocytic hepatitis, also there is focal gliosis. Conclusion, intranasal infection was the effective route and the main pathological changes observed in the respiratory system characterized by fibrinous pleuropneumonia

اعدت هذه الدراسة لغرض معرفة امراضية جرثومة الباستوريلا مالتوسيدا في الاصابة الطبيعية والمقارنة بين الأصابة التجريبية عن طريق التنفس و عن طريق العين باعتبارها الطرق الطبيعية للاصابة.قسمت ثلاثون (30) ارنبا الى ثلاث مجاميع, المجموعة الاولى (12) ارنبا اصيبت عن طريق التنفس ب (240) CFU من جراثيم الباستوريلا مالتوسيدا, المجموعة الثانية (12) ارنبا اصيبت عن طريق التقطير بالعين ب (240) CFU من جراثيم الباستوريلا مالتوسيدا, والمجموعة الثالثة (6) ارانب عدت كمجموعة سيطرة. أجريت الصفة التشريحية على الحيوانات الهالكة والمقتولة بعد 24, 48ساعة وكذلك3, 6, 9, 30 يوم بعد الاصابة.اوضحت النتائج ظهور الخمول والافرازات الانفية والعينية وموت بعض الحيوانات بعد 48-72 ساعة بعد الاصابة. وبين الفحص العياني للحيوانات الهالكة والمقتولة وجود نزف في المجرى التنفسي العلوي مع التهاب الخلب و التامور الليفيني مع وجود النفاخ في الرئة في حيوانات المجموعة الاولى اما حيوانات المجموعة الثانية عانت من عتامة وتورم العين في بعض الحيوانات أضافتا لما وجد في حيوانات المجموعة الاولى وقد تم عزل جرثومة الباستوريلا مالتوسيدا من كافة الاعضاء الداخلية للحيوانات المصابة.وكانت الافات النسيجية المرضية في حيوانات المجموعة الاولى اكثر شدة من المجموعة الثانية حيث تركزت في المجرى التنفسي العلوي والسفلي والمتمثلة بالتهاب الرغامي النزفي مع التهاب الرئة الليفيني, اما الكلية فاظهرت زريدة خلوية الكبيبة مع تنكس ظهارة النبيبات الكلوية بالاضافة الى التهاب الكبد و الدباق البؤري في متن الدماغ. نستنتج من ذلك بأن الاصابة عن طريق التنفس هي الأكثر تأثيرا وتركزت الغيرات المرضية في الجهاز التنفسي حيث تمثلت بالتهاب الرئة والجنب الليفيني.

Abstract

The aim of the study was to explore the clinical and anatomical changes occured after Sciatic nerve section in the weaning age in rabbits. Twenty-five rabbits were used in this study ranging from 1-2.5 months. Divided into five subgroups according to the number of survival days (W7) (W14) (W30) (W60) (W90). Surgery was performed under general anesthesia. The nerve was sectioned using a small surgical scissor. Clinicalay few days later, the sign of right hind paws paralysis was observed clearly. The results revealed of a gap formation between the two nerve stumps [proximal and distal], and the gap increases on the day fourteenth.During the following two weeks, ulcers began to appear in the skin at the dorsal side of the ankle joint, and there was also an enlarged popliteal lymph node. Within 30-60 days another area was invaded by ulcer with or without bone exposure, the anterior part of the posterior side of the hind limb. After 90 days, there was severe ulceration and bone exposure with enlarged lymph nodes and the ulceration extended to the ventral side of the hindlimb. Results showed a gradual worsening of the condition and without improvement in peripheral nerves.

الهدف من هذه الدراسة هو معرفة التغيرات السريرية والتشريحية التي تحدث بعد قطع العصب الوركي في عمر الفطام في الارانب. استعملت 25 أرنبا في هذه الدراسة تتراوح اعمارهم مابين 1-2.5 شهر. تم تقسيمها إلى خمس مجموعات فرعية وفقا لعدد ايام بقائها بعد العملية (W7) (W14) (W30) (W60) (W90) .أجريت العمليات الجراحية تحت تأثير التخدير العام. تم قطع العصب بواسطة مقص جراحي صغير. سريرياً وبعد بضعة أيام، لوحظ بوضوح وجود شلل في الطرف الخلفي الأيمن. وكشفت النتائج عن وجود فجوة بين نهايتي الأعصاب المقطوعة [الدانية والقاصية]،وتزداد الفجوة في اليوم الرابع عشر. وخلال الأسبوعين التاليين بدأ ظهورتقرح في الجلد من الجانب الظهري من مفصل الكاحل، كما لوحظ ان هناك تضخم في العقدة اللمفاوية المأبضية. وخلال فترة 30-60 يوما غُزِيت منطقة أخرى بالقرحة مع أو بدون تعري للعظام، وهي الجزء الأمامي من الجانب الظهري من الطرف الخلفي. وفي يوم 90، كان هناك تقرح شديد وتعري العظام مع تضخم العقد الليمفاوية وأمتد التقرح إلى الجانب البطني للطرف الخلف. دلت النتائج على تردي الحالة بصورة تدريجية وعدم وجود تحسن في الاعصاب الطرفية.

Abstract

The purpose of this study was to evaluate the effects of an autologous platelet rich-plasma on femoral fracture healing in experimentally induced rabbits’ model. In this study, 34 local breed rabbits, around 2-2.5 kg body weight, were divided into two equal groups randomly; Group A: platelet-rich plasma (PRP) and Groups B: Control group. Rabbits in both groups underwent a complete mid-shaft transverse osteotomy of the femur by a fine electrical saw. After fracture induction, the rabbits in group A (PRP group) were treated by application of 0.5 ml of autologous PRP at the site of the fractured bone, while in group B (control), rabbits were injected with distilled water. Samples from the fractured femur were collected at 10th, 20th, 30th days post operation for radiological evaluation and at 10th, 14th, 20th, and 30th days for histopathological evaluation. In radiological study, it was found that the rate of callus formation in rabbits treated with PRP (Group A) were faster than the control group (Group B) at different periods. Similarly, in histological finding it found that the stages of healing were faster in Group A when compared with Group B. It was concluded that using autologous PRP has beneficial effect to enhance the process of bone healing in the rabbit’s model.

Abstract

Background: Bone healing of fractures is still an open field for research due to its biological complexity. Adequately adapted experimental model is essential for understanding the factors influencing the biological process of bone healing. Rabbits provide a good animal model for bone healing studies; its bone had Haversian system similar to human.
Material and Methods: Six young locally breaded New Zeeland male rabbits were used in this study, the study conducted in animal house in college of medicine at November and December 2009. Surgical fracture (osteotomy) induced operatively in right ulna under general anesthesia by a hand saw. At the end of fifth weeks, the animals' scarified and the specimens taken for radiological, computerized tomography (CT) scan densimetry and histological examination carried out for bone healing in site of osteotomy
Results: All bone osteotomy united at end of fifth weeks macroscopically and radiologically. There was no significant difference in serum calcium, serum phosphate, and serum alkaline phosphatase preoperatively and at end of fifth weeks. The callus density was measured in site of osteotomy by CT scan densimetry and its mean was 302 ± 142. The histological examination of the bone at site of osteotomy show healing with woven bone predominantly with some lamellar bone and cartilage. Conclusion: The present study demonstrated that the ulnar osteotomy without use of external splintage or internal fixation model is a new, easy to perform and can be used as a model for fractures healing studies.

Abstract

Abstract: This experiment was conducted to study the effect of Laser treatment on LH, FSH, Progesterone and Cortisol and the relationship between them and after physiological functions in adult female rabbits serum affected with hyperthyroidism. Eighteen adult female rabbits at eight months and weighing (1.2 - 1.8 Kg) were used in this experiment. At the end of the two weeks of adaptation, the rabbits were divided equally into three groups. The first group was given distilled water and used as a control. The second and third groups were administered orally with L- thyroxine at a dose of 200µg/Kg body weight daily for twenty days. After the induction of hyperthyroidism, the third group was exposed to laser treatment (40J / cm2) at the thyroid gland region for fifteen successive days for ten minutes on each side of the gland. Where as the second ( hyperthyroid ) group was left without laser treatment. Blood samples were collected from ear vein and LH, FSH, Progesterone and cortisol levels in serum were assayed. On the other hand food, water intake, body temperature and weight of all animals were estimated. The result show significant increase in these hormones in the second group with an increase food, water intake and body temperature as compared with control. The relationship between these hormones and thyroid gland was discussed. Laser treatment to the hyperthyroid gland seems to normalize these hormones.

الخلاصة: صمم هذا البحث لدراسة تأثير العلاج بالليزر على الهرمون اللوتيني, هرمون محفز الجريبات, البروجستيرون والكورتيزول والعلاقة بين الهرمونات ووظائف فسلجية اخرى, في الارانب المصابة بتضخم الغدة الدرقية. تم استخدام 18 أرنب بالغ من الاناث بعمر ثمانية اشهر ووزن (1.2- 1.8 كغم). تركت اسبوعين كفترة تاقلم ثم قسمت الى ثلاثة مجاميع متساوية. المجموعة الاولى جرعت بالماء العادي اما المجموعة الثانية والثالثة جرعت بهرمون الدرقين بجرعة 200 مايكروغرام/كغم من وزن الجسم يوميا ولمدة 20 يوماً. بعد ظهور علامات تضخم الغدة تعرضت المجموعة الثالثة لاشعة الليزر بجرعة ( 40جول / سم2 ) على منطقة الغدة الدرقية لمدة خمسة عشر يوماً متتابعة وبواقع 10 دقائق لكل جهة من الغدة بينما تركت المجموعة الثانية بدون علاج بالليزر. تم سحب الدم من الوريد الاذني الحافي واستخدم المصل لقياس هرمونات الكونادوتروبين (الهرمون اللوتيني وهرمون محفز الجريبات) وكذلك هرمون البروجستيرون والكورتيزول. من الناحية الخرى تم حساب كمية العلف والماء المستهلك, درجة حرارة ووزن الجسم للحيوانات. اوضحت النتائج ارتفاع معنوي بمستوى هذه الهرمونات في الحيوانات المصابة بتضخم الغدة الدرقية مع زيادة كمية العلف والماء ودرجة حرارة الجسم ونوقشت العلاقة بين الهرمونات والغدة الدرقية. كما تبين ان العلاج بالليزر أعاد الهرمونات الى مستواها الطبيعي في الحيوانات المصابة بتضخم الغدة الدرقية.
