Alcohol abuse and its medical and social consequences are a major health problem in many areas of the world. Korean red ginseng (KRG) has been traditionally used for the treatment of liver disease. This study was conducted to evaluate the hepatoprotective effects of KRG against hepatotoxicity in Sprague-Dawley rats treated with ethanol (EtOH). Administration of EtOH for 20 days induced significant changes in serum biochemical parameters (aspartate aminotransferase, alanine transaminase, and glucose) accompanied by histological changes in the liver tissue. Treatment with KRG prior to administration of EtOH inhibited the EtOH-induced biochemical and histological changes of the liver. In perfused rat livers, administration of EtOH caused an increase in lactate dehydrogenase (LDH) release into the perfusate and activated the pro-apoptotic Bax protein but inhibited the anti-apoptotic Bcl-2 protein. Pretreatment with KRG prior to administration of EtOH decreased the EtOH-induced LDH release and inhibition of Bcl-2 protein. These results suggest that KRG exerts anti-apoptotic effects and alleviated EtOH-induced liver injury in rats.

Quercetin and resveratrol are known to have beneficial effects on the diabetes and diabetic complication, however, the effects of combined treatment of these compounds on diabetes are not fully revealed. Therefore, the present study was designed to investigate the combined antidiabetic action of quercetin (QE) and resveratrol (RS) in streptozotocin (STZ)-induced diabetic rats. To test the effects of co-treated with these compounds on diabetes, serum glucose, insulin, lipid profiles, oxidative stress biomarkers, and ions were determined. Additionally, the activities of hepatic glucose metabolic enzymes and histological analyses of pancreatic tissues were evaluated. 50 male Sprague-Dawley rats were divided into five groups; normal control, 50 mg/kg STZ-induced diabetic, and three (30 mg/kg QE, 10 mg/kg RS, and combined) compound-treated diabetic groups. The elevated serum blood glucose levels, insulin levels, and dyslipidemia in diabetic rats were significantly improved by QE, RS, and combined treatments. Oxidative stress and tissue injury biomarkers were dramatically inhibited by these compounds. They also shown to improve the hematological parameters which were shown to the hyperlactatemia and ketoacidosis as main causes of diabetic complications. The compounds treatment maintained the activities of hepatic glucose metabolic enzymes and structure of pancreatic β-cells from the diabetes, and it is noteworthy that cotreatment with QE and RS showed the most preventive effect on the diabetic rats. Therefore, our study suggests that cotreatment with QE and RS has beneficial effects against diabetes. We further suggest that cotreatment with QE and RS has the potential for use as an alternative therapeutic strategy for diabetes.

Hamartomas are non-neoplastic malformations or congenital errors of tissue development. Hamartoma is composed by an excessive growth of mature tissue present in wrong proportions and abnormal arrangements. The lesion usually presents as a submucosal mass with ill-defined margins. Hamartoma occurs in all areas of the body, especially in the liver, spleen, kidney and lung. However, hamartoma is very rare in the head and neck. Presenting symptoms of hamartoma are typically vague and nonspecific. Treatment of hamartomas consists of adequate surgical excision. We present a 59 year-old male patient who presented with submental swelling. Malignancy could not be ruled out with preoperative radiologic examination, so surgical excision was planned. The mass was excised with transcervical approach. Histopathologic examination has confirmed the mass as a mucinous gland adenomatoid hamartoma.

Introduction: The current standard treatment for ankle
syndesmosis injury is static screw fixation. Dynamic fixation
was developed to restore the dynamic function of the
syndesmosis. The purpose of this study was to determine that
which of static screw fixation and dynamic fixation is better
for treatment of ankle syndesmosis injury in pronationexternal rotation fractures.
Materials and methods: Thirty patients were treated with
dynamic fixation (DF group) and 28 patients with static
screw fixation (SF group). The primary outcome was
Olerud–Molander Ankle Outcome Score. The secondary
outcome were Visual Analogue Scale score and American
Orthopedic Foot and Ankle Society score, radiographic
outcomes, complications and cost effectiveness. To evaluate
the radiographic outcome, the tibiofibular clear space,
tibiofibular overlap, and medial clear space were compared
using the pre-operative and last follow-up plain radiographs.
To evaluate the cost effectiveness, the total hospital cost was
compared between the two groups
Results: There was no significant difference in primary
outcome. Moreover, there were no significant difference in
secondary outcome including Visual Analogue Scale score
and American Orthopedic Foot and Ankle Society score and
radiographic outcome. Two cases of reduction loss and four
cases of screw breakage were observed in the SF group. No
complication in the DF group was observed. Dynamic
fixation was more cost effective than static screw fixation
with respect to the total hospital cost.
Conclusion: Although dynamic fixation provided similar
clinical and radiologic outcome, dynamic fixation is more
cost effective with fewer complications than static screw
fixation in ankle syndesmosis injury of pronation-external
rotation fractures.
