Bromelain is isolated from the stems, leaves and the skin of pineapple by employing modern biological extraction technology. it is composed of protease and many others contents. its activity specification is indicated of GDU./g and the maximum activity specification can reach up to 3000 GDU/g. Bromelain could hydrolyze the protein and have many kinds of biochemistry responses, and so is widely applied in the medical, health products, food, cosmetics, forage, leather industry and so on. Because it has the function of strongly decomposing fibrin and the blood clot, therefore especially is remarkable effect on the medical application.

The anti- tumor activeness of activity was mainly the function of dissolving activity and suppressing blood platelet polymerization, and has disturbed the blood textile fiber and tumor cell congealing.

Bromelain is a protein hydroltyic enzyme which is beneficial for controlling the cardio vascular disease. It can suppress heart attacking which the blood platelet gathering causes with the stroke, alleviate the angina pectoris sym-ptom,relaxe the artery contraction, and accelerate decomposition of fibrinogen.

some component of bromelain may be used in treating the immunity system illness which
suppresses or took to be the vaccine adjuvant, patients who lack of the gammag lobulin
phagocyte in the blood display the kind of stimulation specially sensitively, by the st-
imulation of assistance cell and to directly inhibiting reaction T cell,bromelain maystr-
engthen and suppress the immune response of the T cell.

The experiment proved that bromelain can reduce the activity of toxin union, and can suppress the secretion effect on the thermal instability toxin (L I),cholera toxin (C T) and the heatstable toxin (S T).

Bromelain can selectively remove the shameless, and transplant the new skin as soon as possible.The animal experimentation proved, bromelain does not have bad influence to normal skin. The partial u-sing antibiotic does not affect the effect of the bromelain, may remove the scab in 3-4 hours. The entire process does not need anaesthetize, and remove the scab extremely,it has a more vital sign ificance for burning treatmen tre-garding the function spot.

bromelain has the potention of activating inflammation response, mixing bromelain and the antibiotic and other enzymes has good curative effect on treating the rheumatic arthritis, bromelain also may treat the diarrhea.

Maxing bromelain and some antibiotics (for example tetracyclin, Arab Xilin and so on) ,can enhance its curative effect. The correlation research indicated, It can promote the transmission of the antibiotic in the infection spot, and so reduce the does of the antibiotic.

Bromelain is absorbed in the animal intestines by 40%, Volunteers who takes bromelain, also may obviously measure bromelain in the blood. Bromelain circulates in the blood, and mixes with partial certain protein.
