Influence of Platelets Rich Plasma on Repair of Superficial Digital Flexor Tendon Rupture in Donkeys (An Experimental Study)

This study was planned to prospectively evaluate the influence of platelets rich plasma (PRP) on the restoration of superficial digital flexor tendon (SDFT) in donkeys. Eighteen apparently clinically healthy male donkeys of 3-6 years old, weighing 150-200 kg, were used. The animals were classified into two equal groups; control group and PRP group. One cm transection of the full thickness of middle portion of the SDFT was made in all animals. First, all animals were subjected to sedation via xylazine HCl injection in a dose of 1 mg/kg body weight then the animals were deeply narcotized with chloral hydrate 10% in a dose of 5 gm/50 kg body weight. A linear skin incision in the palmar aspect of the right fore limb at the mid cannon region was performed in all operated animals. The animals in PRP group were subjected to intratendinous injections of 4 mL PRP with weekly interval (day 0, w1, w2, w3) under the guidance of ultrasonography. Representative tendon specimens from all animals were collected 30, 60, and 90 days post operation (PO) for histopathological examination. The obtained clinical and histopathological results reveled that PRP application improved the healing of SDFT compared to the control group, through increasing and acceleration of angiogenesis, fibrogenesis, collagen deposition and remodeling in the injured tendon matrices

Dental disorders in dogs and cats: A retrospective study

The study was conducted on 289 clinical cases of dogs and cats admitted to the Clinic of Department of Surgery, Anesthesiology, and Radiology, Faculty of Veterinary Medicine, Zagazig University, over 18 months. Thorough oral, dental, and radiographic examinations were performed on all cases. Disorders were recorded in a predesigned survey sheet along with several factors such as breed, age, sex, diet, and body condition score. Cases were categorized into four groups according to age. The results revealed that 138 (47.75%) of the total cases have dental disorders, 81 (58.7%) males and 57 (41.3%) females. Periodontal diseases were the most recorded affection 128 cases. Among animals admitted to the department clinic, then dental plaque (111 cases). Animals on soft food diet among total affected cases recorded, 89 cases (64.5%), then mixed diet (soft and hard food) 40 cases 29% and the last group dry or hard diet, 9 cases only 6.5%. The most affected breeds were German shepherd dogs 5.797% and Shirazy cats 57.97%. Data statistical analysis showed that age and diet had (P<0.05), which means that these two factors impacted the occurrence of dental disorders, in contrast, sex had (P= 0.143), which indicates that sex statistically did not affect the occurrence of dental disorders, moreover a spearman correlation test was performed between age and dental disorders (P<0.05) and revealed that, with an increase in age, there is an increase in dental disorders
