The effects of increased heme oxygenase-1 on the lymphoproliferative response in dogs with visceral leishmaniasis.

abstract：BACKGROUND:Male reproductive tract infection and inflammation are important aetiological factors of infertility. Experimental Autoimmune Orchitis (EAO) is a model of chronic inflammation useful to study mechanisms of inflammatory reactions leading to testicular impairment. EAO is characterised by interstitial cell infi...
