Change of voltage-gated potassium channel 1.7 expressions in monocrotaline-induced pulmonary arterial hypertension rat model
Hyeryon Lee, Kwan Chang Kim, Young Mi Hong
Clin Exp Pediatr. 2018;61(9):271-278.   Published online September 15, 2018

Purpose: Abnormal potassium channels expression affects vessel function, including vascular tone and proliferation rate. Diverse potassium channels, including voltage-gated potassium (Kv) channels, are involved in pathological changes of pulmonary arterial hypertension (PAH). Since the role of the Kv1.7 channel in PAH has not been previously studied, we investigated whether Kv1.7 channel expression changes in the lung tissue of a monocrotaline...

Oxidative stress and the antioxidant enzyme system in the developing brain
So-Yeon Shim, Han-Suk Kim
Clin Exp Pediatr. 2013;56(3):107-111.   Published online March 18, 2013

Preterm infants are vulnerable to the oxidative stress due to the production of large amounts of free radicals, antioxidant system insufficiency, and immature oligodendroglial cells. Reactive oxygen species (ROS) play a pivotal role in the development of periventricular leukomalacia. The three most common ROS are superoxide (O2•-), hydroxyl radical (OH•), and hydrogen peroxide (H2O2). Under normal physiological conditions, a balance...

Clin Exp Pediatr. 2011;54(7):313-315.   Published online July 31, 2011

Reactive arthritis comprises a subgroup within infection-associated arthritides in genetically susceptible hosts. Researchers and clinicians recognize two clinical forms of reactive arthritis which occurs after genitourinary tract infection and after gastrointestinal tract infection. Chlamydia infection has been implicated as the most common agent associated with post-venereal reactive arthritis. Studies have proposed Shigella infection, Salmonella infection, or Yersinia infection as the...

Clin Exp Pediatr. 1987;30(9):1014-1020.   Published online September 30, 1987
Urinary tract infection (UTI) in children is relatively common infectious disease and it may be the forerunner of severe renal diseases in adulthood. The site of infection is an important factor in the evaluation of the clinical course, treatment and prognosis of patients with UTI, because patients with bacteriuria of renal origin (pyelonephritis) are probably at risk of developing the renal parenchymal reduction seen...
