Introduction: The aim of this study was to investigate fluorescein use in the diagnosis of bladder ruptures in rabbits as an experimental model.Material and Methods: The study was conducted on male New Zealand rabbits divided into a retrograde fluorescein group (n = 8) and an intravenous (IV) fluorescein group (n = 8). Following general anaesthesia, 10 mL of 10% fluorescein dye (sodium fluoresceine powder) was administered via ureterorenoscope to the bladder of the first group, and 0.5 mL of 10% fluorescein was administered intravenously to the second group. Then, the bladder was viewed through the cystoscope by urethral aspect. After experimental bladder perforation, groups were comparatively evaluated by paracentesis and laparotomy.Results: Following IV injection of fluorescein dye, the bladder veins were stained green within 10 s and then fluorescein mixed with urine flowed into bladder lumen. The green fluid flow was observed in the abdominal cavity after the perforation of the bladder in both groups.Conclusion: Fluorescein can be used as a marker in diagnosis of bladder ruptures. If there is no bleeding or intestinal content in the abdominal cavity, although a smoky yellow-green image is observed, bladder rupture can be suspected.

The study was conducted toknow the anatomy of the brachial plexus ofWhite New Zealand Rabbit (Oryctolaguscuniculus). Ten healthy male and femaleWhite New Zealand rabbits were dissectedin this study. It was found that the brachialplexus of the White New Zealand Rabbitwas formed by ventral branches of C5,C6, C7, C8, T1 and T2 spinal nerves.The cranial trunk was formed by thecaudal branch of C5, C6 and caudal trunkformed by rami ventralis of C7, C8, T1and the cranial branch of ventral ramusof T2. Cranial pectoral nerve originatedfrom the caudal trunk spreading into thepectoral muscles. The musculocutaneousnerve innervates into the brachial muscleand the axillary nerve into the subscapularmuscle. The radial nerve was dividedinto two branches as ramus profundusand ramus superficial then divided intothe digital dorsal common III and IV.The thoracodorsal nerve innervates thelatissimusdorsi muscle. The median nervewas divided into digital dorsal commonI, II, III and IV nerves. The ulnar nerveformed the caudal cutaneous antebrachialthen digital dorsal common IV and Vnerves. Lateral thoracic and caudal pectoralnerves originated from the caudal trunk.The origin and distribution of brachialplexus resemble that of porcupines butdiffer from other mammals.
