Jimin Kahng, So-Young Kim
Clin Exp Pediatr. 2007;50(12):1257-1260.   Published online December 15, 2007
E. histolytica has a simple life cycle with two stages: an infective cyst and an invasive trophozoite. It lives on humans as its host. Its infection occurs through the ingestion of the cyst form, and the disease begins when the trophozoite, converted at the small intestine, adheres to colonic epithelial cells with a latent period of two days to four...

Infection and Innate Immunity
Moo-Young Oh
Clin Exp Pediatr. 2005;48(11):1153-1161.   Published online November 15, 2005
As known by other name(natural immunity), the innate immune system comprises all those mechanisms for dealing with infection that are constitutive or built in, changing little with age or with experience of infection. Though in some ways less sophisticated than adaptive immunity, innate immunity should not belittled, since it has evidently protected thousands of species of invertebrates sufficiently to survive...

Jae Ho Lee
Clin Exp Pediatr. 2005;48(5):461-468.   Published online May 15, 2005
The major function of immune system is to protect infections. The immune systems are composed of innate and adaptive immunity. In adaptive immunity, the cellular and humoral components interact each other. Neonates and infants are infected frequently, because immune systems are naive and easy to expose to infectious agents. The complete history and physical examination is essential to evaluate the...
