研究室紹介

Professor Ji Hoon Na's research lab focuses on translational and clinical studies in hepatology and mitochondrial disorders, with a particular emphasis on portal hypertension and mitochondrial disease-related ophthalmoplegia. The lab investigates pharmacological interventions—such as ARB and beta-blocker combinations—for cirrhotic patients, while also exploring the clinical classification, diagnosis, and natural history of rare neurologic conditions like Kearns-Sayre syndrome and Tolosa-Hunt syndrome. Additionally, the lab contributes to materials science through studies on III-V semiconductor surfaces, particularly InGaAs, for next-generation semiconductor devices.

Effects of candesartan and propranolol combination therapy versus propranolol monotherapy in reducing portal hypertension
Jae Hyun Kim, Jung Min Kim, Youn Zoo Cho, Ji Hoon Na, Hyun Sik Kim, Hyoun A Kim, Hye Won Kang, Soon Koo Baik, Sang Ok Kwon, Seung Hwan, Young Ju Kim, Moon Young Kim
SJR Q1Clinical and Molecular HepatologyOA

The addition of candesartan (an ARB) to propranolol confers no benefit relative to classical propranolol monotherapy for the treatment of portal hypertension, and is thus not recommended.

Ophthalmoplegia in Mitochondrial Disease
이상준, 나지훈, 한진우, 이영목

Purpose: To evaluate the classification, diagnosis, and natural course of ophthalmoplegia associated with mitochondrial disease. Materials and Methods: Among 372 patients with mitochondrial disease who visited our hospital between January 2006 and January2016, 21 patients with ophthalmoplegia were retrospectively identified. Inclusion criteria included onset before 20 years of age, pigmentary retinopathy, and cardiac involvement. The 16 patients who were finally included in the study were divide

Background/Aims: Angiotensin receptor blockers (ARBs) inhibit activated hepatic stellate cell contraction and are thought to reduce the dynamic portion of intrahepatic resistance. This study compared the effects of combined treatment using the ARB candesartan and propranolol versus propranolol monotherapy on portal pressure in patients with cirrhosis in a prospective, randomized controlled trial. Methods: Between January 2008 and July 2009, 53 cirrhotic patients with clinically significant porta

Transient and Adult Patients with Neurologic Diseases in the Pediatric Emergency Department: Trends and Characteristics
나지훈, 이영목
https://doi.org/10.3988/jcn.2019.15.2.191

Background and Purpose There is an increasing rate of presentations by transient and adult patients (TAPs) to pediatric emergency departments (PED-EDs). TAPs with neurologic diseases (N-TAPs) comprise most of these patients. We investigated this trend and compared the characteristics of N-TAPs with those of pediatric patients with neurologic diseases (N-PEDs) who presented to the PED-ED of a tertiary-care hospital in Korea. Methods We reviewed the medical records of neurologic patients who prese

The Clinical Significance of Serum Ferritin in Pediatric Non-Alcoholic Fatty Liver Disease
나지훈, 박소원, 강윤구, 고홍, 김승
Pediatric Gastroenterology, Hepatology & Nutrition

Purpose: Non-alcoholic fatty liver disease (NAFLD) in children has become an important public health issue because of its high prevalence and severity. Several noninvasive methods for estimating NAFLD are under investigation. We aimed to evaluate the usefulness of serum ferritin as a biomarker of severity of pediatric NAFLD patients. Methods: A total of 64 NAFLD patient were enrolled from Severance Children’s Hospital from March 2010 to February 2013. Serum ferritin levels, liver related laborat

Phosphoric acid-peroxide mixture surface preparation for the improvement of InGaAs channel characteristics
나지훈, 임상우

InGaAs is a potential candidate for a next-generation channel material of complementary metal-oxidesemiconductordevices based on its excellent electron mobility. In this study, the surface behaviors ofthe InGaAs after treatments in H3PO4/H2O2/H2O and HNO3/H2O2/H2O mixtures were investigated andcompared with that after treatment in a HCl/H2O2/H2O mixture. Although the presence of Cl in an acidicsolution suppressed the overall etching reaction and material loss of the InGaAs surface, Cl induced th

Therapeutic Approach to Epilepsy in Patients with Mitochondrial Diseases
나지훈, 이영목
https://www.eymj.org/DOIx.php?id=10.3349/ymj.2024.0325

Mitochondrial diseases (MDs) are genetic disorders with diverse phenotypes that affect high-energy-demand organs, notably the central nervous system and muscles. Epilepsy is a common comorbidity, affecting 40%–60% of patients with MDs and significantly reducing their quality of life. This review discusses the different treatment modalities for epilepsy in patients with MDs. Advances in genetic sequencing have identified specific mutations in mitochondrial and nuclear DNA, enabling more precise d

Purpose: To analyze the efficacy and safety of nusinersen in patients with spinal muscular atrophy (SMA) type I with chronic re spiratory failure. Materials and Methods: We retrospectively reviewed seven patients diagnosed with SMA type I and chronic respiratory failure who were on permanent ventilation and treated with nusinersen at Gangnam Severance Hospital between January 2018 and July 2023. Patient demographics and clinical characteristics were recorded, and treatment progress was evaluated

Most ingested foreign bodies pass readily throughout intestinal tract if they reach the stomach. In some cases, foreign bodies may be impacted behind a luminal constriction but are rare in colon. Here, we report the case of a 59-year-old man who did laparoscopic anterior resection due to sigmoid colon cancer 2 years ago and ischemic colitis was repeated on the anastomosis site. He initially presented with symptoms of abdominal pain 3 months before and melena 1 day before admission. Abdomen compu

Age-Based Characteristics of West Syndrome in Patients with Mitochondrial Disease
최영하, 백민성, 나지훈, 강훈철, 이준수, 김흥동, 이영목

Purpose: West syndrome is a severe form of age-specific epilepsy that typically affects infants younger than 2 years of age with mitochondrial disease. We aimed to examine age-specific characteristics of the syndrome in these patients. Methods: We retrospectively analyzed 54 patients with West syndrome diagnosed with mitochondrial disease between March 2006 and March 2016. We compared treatment strategies and diagnostic and clinical variables between patients with early-onset (<6 months of age)
