الملخص EN

Camellia sinesis is one of the most important plants were used in the life.

The important of tea plant varies with its used , antioxidant ,antibacterial ,lowering of plasma cholesterol levels and activation of leucocytes. Oraly and injection method were used for to detect the immunological activity in rabbit.

Animals were given 5 ml of extract orally and 0.5 ml of extract mixed with 0.5 ml of oil adjuvant by injection . The effect of tea extract varies in according to method at P ≥ 0.05 .The effect was shown specific mucosal and systemic antibodies at higher titers, 32 ,16 in mucosal and 320,160 in systemic .Significant variable in orally methods than injection at P ≥ 0.05 .Lymphocyte inhibitor factor (LIF) was stimulated in systemic and mucosal by tea extract ,there some variable between orally and injection method .

Total protein was increased compared with control, while mucosal protein was decreased compared with control ,so the comparative between two methods are variable at P ≥ 0.05.
