Outflow of fluorescent dextran in anterior chamber of rats and its distribution in lymphoid organs;

Mast cells in the lymphoid organs of Ctenopharyngodon idella;

Histological studies on lymphoid organ of Penaeus chinensis;

The lymphoid organ of penaeid shrimp is the important organ related with the shrimp immunity.

Characteristics of mast cell distribution in major lymphatic organs of rabbit;

One hundred and fourty adult Wanxi white geese of different sexual developmental stage were anatomized macroscopically and the morphological characteristics of lymphatic organ observed including the thymus, bursa Fabricius, spleen, lymphadens lumbales, cervicales and thoracicus.

This experiment,using HVT vaccine to inject into 18 days chicken embrio for getting seminal immunity,showed that the development of lymph organ in early stage of the chicken of 18 days embyio immunity appeared an obvious hestening effect from histology,histological chemistry,and ultramicroscopic structure of lymph organ of encubated chicken.

The histochemical staining methods were employed to investigate the quantity,activity,distributive pattern and histochemical property of mast cells in the lymph organ during the hibernation of bufogargarizans.

In the present study,It was demonstrated that large numbers of mast cells distributed in the chicken lymphatic organs(thymus,spleen and bursa of Fabricius)by histochemical methods using routine toluidine blue(RTB),long toluidine blue(LTB),alcian blue safranin(AB S),aldehyde fuchsin alcian blue(AF AB)and alcian blue periodic acid schiffs reaction(AB PAS).

In the present study, it was demonstrated that large numbers of mast cells occurred in the duck lymphatic organs.
