Now the trial and use of S for the treatment in RDS...
Experimental study on the effect of phenobarbital on Na+, K+-activated adenosine triphosphatase in microsome fractions of mouse brain.
Seo Kyu Kim, Sa Jun Chung, Chang Il Ahn
Clin Exp Pediatr. 1991;34(7):959-970.   Published online July 31, 1991
Na+, K+-activated adenosine triphosphatase (Na+, K+-ATPase) is known to play a role as a trigger in neurotransmitter release and may also affect the transport of calcium ion (Ca++). By doing so, Na+, K+-ATPase, as an anticonvulsant, can modify the excitability level of cells in epilepsy. In order to elucidate the possible mechanisms of neuropharmacological interaction between Na+, K+.ATPase and phenobarbital, serial experimental studies were...

More recently, several studies have been repotted about the abnormalities of auditory brainstem response (ABR) in hyperbilirubinemia of newborn. By using of ABR, visual evoked potenital and nuclear magnetic resonance techniques, some investigators suggested that transient alteration in ABR in severely jaundiced neonates indicated reversible transient subclinical or clinical bilirubin induced neurotoxicity. They thought it would be the early stage of kernicterus. We experienced two...

Sang Young Jeong, Soo Chun Kim, Sung Ho Cha, Young Mook Choi, Chang Il Ahn
Clin Exp Pediatr. 1989;32(8):1132-1137.   Published online August 31, 1989
Doxorubicin is one of the most effective chemotherapeutic agents in the treatment of leukemia, lymphoma and various solid tumors. Because of dose-dependent degenerative cardiomyopathy, however, doxorubicin theraphy may be discontinued ineffectively early. Doxorubicin-induced conges- tive heart failure carries a very poor prognosis since it is lethal in 60% of patients. Various methods for evaluating the cardiotoxic effect have been employed such as EKG, systolic...
