New Zealand Black (NZB) mice have long been exploited as a model of genetically controlled autoimmune diseases and immunoregulatory dysfunction (1-3). Of particular concern to us is the unusual development and function of their humoral immune system. There is reason to believe that spontaneous and polyclonal activation of B cells occurs independently of defects residing in thymus-derived (T) ce...

objective: gastric dilatation also known as gastrointestinal obstruction or bloat is an acute and life-threatening condition in pet rabbits commonly caused by an intestinal obstruction with pellets, foreign bodies and compressed hair. methods: in june 2014, a two years old male new zealand white rabbit were referred to karaj central veterinary hospital, karaj, iran with the history of acute ano...

Physicochemioal investigations of the last years have shown that the interferons represent a very heterogenous class of molecules. Differences are not only related to the molecular weights but also to the isoelectric behaviour. Electrofocusing demonstrated that depending on the cellular origin even interferon of one species as chick interferon 1 , interferons of mouse2, rabb i t 2 4 and human c...

Exposure of rabbit reticulocytes to agents which damage the cell membrane by a variety of different mechanisms stimulates the incorporation of radioactive acetate and glycerol into membrane lipids. An increase in the rate of lipid synthesis occurs within minutes at 37’C at concentrations of the agents which do not cause spontaneous cell lysis. Different agents do not increase synthesis of diffe...

Background: Gastrointestinal (GI) endocrine cells produce many GI hormones that perform various physiological functions of the digestive system. Aims: We aimed to investigate the presence and distribution of immunoreactive (IR) endocrine cells to glucagon, somatostatin, cholecystokinin-8 (CCK-8), serotonin, secretin and histamine in the stomach of adult male Ne...

Environmental enrichment diminishes abnormal behaviors in laboratory animals such as rodents, lagomorphs, dogs, cats, and nonhuman primates. Thirteen male single housed New Zealand White rabbits were offered three different toys and the time spent chewing on the toys instead of on the cage was evaluated. Every toy was offered to each rabbit for two separate one week periods. Each rabbit was mon...
