“…The sonogram of the normal uncastrated testes showed low to moderate but homogenous echogenicity of the parenchyma with hyperechogenic vaginal tunic. This echotexture mirrors the findings in (Sakthivel et al, 2013;Olatunji-Akioye et al, 2018) and rams (Gouletsou et al, 2003;Andrade et al, 2014). In the Burdizzo castrated bucks, sonogram of testes showed low to moderate parenchyma.…”

“…Bucks were physically restrained by two assistants and the testes immobilized. The parenchyma echotexture of each testis was scanned in the sagittal, and transverse planes and diameters measured using the built-in callipers (Bukar et al, 2012;Sakthivel et al, 2013;Olatunji-Akioye et al, 2018).…”

“…It was suggested that ultrasonography could permit noninvasive evaluation of the internal structure of the scrotum and testes for evaluating physio-pathologic conditions of goat testes or as a routine investigative method during breeding soundness and clinical examination (Sakthivel et al, 2013;Olatunji-Akioye et al, 2018). Furthermore, use of semen analysis in conjunction with sonography is potentially very useful in assessment of fertility status in animals (Gouletsou et al, 2003).…”

We evaluated the efficacy of castration with bilateral intratesticular injections of Calcium Chloride Dihydrate (CaCl2) in ethanol, Olive Oil as well as Burdizzo technique in twenty Sahel bucks. The bucks were randomly distributed into four groups as A, B, C and D. Group A served as the control and were given bilateral intratesticular injection of 1.0 ml of normal saline. Bucks in group B were castrated with Burdizzo, while group C and D were given bilateral intra testicular injection of 1.0 ml of CaCl2 and Olive oil, respectively. The sonograms and semen profiles of the bucks were evaluated.The diameters of the testicles and spermatic cords and the semen parameters were measured in real time after castration at days 1, 7, 14, 21, 28 and 60. The diameters in the Burdizzo, CaCl2‎and Olive oil castrated bucks ‎significantly increased (P < 0.05) on days 7 and was decreased at ‎day 60.‎ Semen motility was absent in the bucks castrated with Cacl2 after day 14. The ‎concentration of spermatozoa also decreased significantly on day 7 in all the Burdizzo, CaCl2‎and ‎Olive oil castrated goats. Sonogram of testes castrated with Cacl2 showed discreet focal ‎hyperechoic, surrounded by ‎hypoechoic areas ‎within the parenchyma due to the CaCl2 deposition. The testes of bucks castrated with olive oil were ‎characterized by a central hypoechoic area ‎surrounded by clearly distinguishable hyperechoic ‎areas within the parenchyma. It was concluded that intratesticular injection with Burdizzo, CaCl2and olive oil resulted in successful castration but CaCl2 injection resulted in earlier azoospermia.

“…Ischemia-reperfusion injury significantly impairs healing of intestinal anastomosis either directly or as a systemic phenomenon (Kuzu et al, 1998;Kuzu et al, 2000). It has been established that damage from an ischemic event is a product of two phases of injury with the most significant occurring after reperfusion, the severity being dependent on the intensity of the insult (Grace, 1994;Schiller et al, 1993;Olatunji-Akioye & Akinrinmade, 2006). When blood flow is restored to ischemic tissues, a local inflammatory response begins, which is then enhanced by the production of bioreactive oxygen radicals , which promote increased mitochondrial membrane permeability (Qian et al, 1997).…”

effects of ischemia-reperfusion on intestinal anastomotic wound healing in dogs. Int. J. Morphol., 25(4):805-810, 2007. SUMMARY:The histopathological effects of three levels of ischemia-reperfusion (IR) on healing of intestinal anastomotic wound were investigated in dogs. Three groups of dogs in which superior mesenteric artery (SMA) and collaterals were isolated but not occluded (A -control), isolated and occluded immediately distal to the aorta with collateral interruption using an atraumatic arterial clip for fifteen minutes (B) and for forty-five minutes (C) prior to ileal resection and anastomosis after return of normal perfusion in occluded groups was done. Within each group, animals were anaesthesized on third and seventh post-operative day. Grossly, impaired abdominal wound healing, intra-abdominal adhesions and partial and complete anastomotic dehiscence occurred in groups B and C commensurate with intensity of ischemic injury. Histologically, light cellular infiltration with loose granulation tissue was observed in the control group with moderate neovascularization and epithelialization by the seventh day. With mild IR, moderate cellular infiltration was observed four days post operation, but heamorrhage and oedema persisted with minimal mucosal regeneration at seven days post operation. With profound IR, sloughing of the mucosa with cellular infiltration at four days with absence of mucosal regeneration and persistence of inflammatory cellular infiltrates minimal neovascularization and dense granulation tissue. Neutrophilia in the immediate post operative period appears significant to impaired healing due to ischemia-reperfusion.
