The present study was to observe the dynamic changes of tyrosine protein ki
nase (TPK) activity in subcellular fractions in the early stage of activati
on of T lymphocytes from normal and traumatized rats, and the regulatory ef
fect of electroacupuncture (EA) stimulation on it. The results showed that
the activities of TPK in membranous and cytosolic fractions of activated T
lymphocytes were increased on second 5, and the peak was on scond 45 after
ConA stimulation. Then it was decreased gradually. Comparing with the contr
ol group, the activities of TPK in membranous and cytosolic fractions of ac
tivated T lymphocytes from the traumatized rats were inhibited in various d
egrees especially in membrane. EA of "Zusanli"(ST36) and "Lanwei"(Extra 33)
points could enhance the activity of TPK in subcellular fractions of activ
ated T lymphocytes from the traumatized rats. The results indicated that EA
stimulation could prevent the inhibition of activation of TPK induced by t
rauma stress, and contribute to transmembrane signal transduction of T lymp
hocytes.
