lymphedema ( J:87394 )
• accumlulation of chylous, milky fluid high in triglycerides in the abdomen
• adults show swelling of the paws
chylous ascites ( J:87394 )
• the stagnant chylous ascites produces an inflammatory response in the abdominal cavity and leads to severe adhesions and fibrosis of the internal organs

immune system
abnormal lymph circulation ( J:87394 )
• cutaneous lymphatic vessels do not uptake dextran as seen in wild-type vessels
• no lymphatic fluid transport of Evans blue dye is observed into the collecting lymphatic vessles after intradermal injection of dye to the hind limbs
lymphatic vessel hypoplasia ( J:87394 )
• severe but transient hypoplasia of the lymphatic vasculature in newborns

cardiovascular system
abnormal lymph circulation ( J:87394 )
• cutaneous lymphatic vessels do not uptake dextran as seen in wild-type vessels
• no lymphatic fluid transport of Evans blue dye is observed into the collecting lymphatic vessles after intradermal injection of dye to the hind limbs
