본 연구는 고혈압이 있는 대한민국 성인에서 아스파르트산 아미노전이효소(aspartate aminotransferase, AST)/알라닌 아미노전이효소(alanine aminotransferase, ALT) 비율과 맥압(pulse pressure, PP) 사이의 관계를 평가하기 위해 수행되었다. 제6차 국민건강영양조사(KNHANES VI-3, 2015)에서 성인 1,515명의 데이터를 분석했다. 본 연구에서는 몇 가지 중요한 결과가 있다. 첫째, AST (odds ratio [OR], 1.018; 95% confidence interval [CI], 1.002~1.033), ALT (OR, 0.982; 95% CI, 0.969~0.996) 및 AST/ALT ratio (OR, 1.367; 95% CI, 1.027~1.819)는 고PP 결정하는 독립적인 요인이었다. 둘째, 관련변수(연령, 성별, 흡연, 음주, 규칙적인 운동, TC, TG, HDL-C, FBG, BMI, WC)를 조정한 후의 결과에서 AST/ALT ratio의 1 사분위에 대한 고PP의 OR을 기준으로, AST/ALT ratio의 2 사분위(OR, 1.188; 95% CI, 0.817~1.727) 및 AST/ALT ratio의 3 사분위(OR, 1.169; 95% CI, 0.800~1.710)는 유의하지 않았지만, AST/ALT ratio의 4 사분위(OR, 1.632, 95% CI, 1.113~2.393)에서 유의하게 높았다. 결론적으로, 고혈압이 있는 대한민국 성인에서 고PP은 AST/ALT ratio 및 AST와 양의 상관관계가 있었지만 ALT와 음의 상관계가 있었다.

Biphenyl Dimethyl dicarboxylate(DDB) has been regarded as a safe, effective drug for decreasing serum aminotransferase levels from elevated serum aminotransferase levels, which cause acute or chronic hepatitis and chronic liver diseases. This study was designed to low dose(22.5mg/day) & short-term therapy effectiveness for 4 weeks of DDB in 30 chronic hepatitis patients with elevated serum aminotransferases. The following results were observed. 1. Serum alanine aminotransferase(ALT) levels significantly decresed from 173. $97\pm130.62(U/L)$ of pretreatment level to $32.23\pm19.22(U/L)$ after treatment for 4 weeks(p<0.00l) and normalized patients by $73\%$ 2. Serum aspartate (AST) aminotransferase levels significantly decreased from $94.90\pm49.17(U/L)$ of pretreatment level to $45.30\pm23.25(U/L)4 after treatment(p0<0.01). 3. However, no significant effects in the serum AST & ALT changes by which cause hepatitis and hepatitis duration (p>0.05). 4. No significant adverse effects were observed except for mild epigastric discomfort in one patient during DDB treatment It is suggested that DDB small dosage administration can result effectively decreasing serum aminotransferase levels from chronic hepatitis patients with elevated serum aminotransferase levels.

본 연구의 목적은 당뇨 검사결과와 간기능검사와의 관계연구이다. 간성당뇨는 제2형 당뇨와는 다르게 간기능 이상으로 기인하는 것이다. 본 연구에서 간기능 검사의 주요 효소검사인 아스파르트산 아미노전이효소(aspartate aminotransferase, AST), 알라닌 아미노전이효소(alanine aminotransferase, ALT) 그리고 AST/ALT ratio (De Ritis ratio)와 당뇨관련 검사와의 관계를 주로 확인하였다. 연구 결과 AST와 글루코스(glucose) (r=0.14, P<0.01); ALT 및 글루코스(r=0.21, P<0.01); AST 및 당화혈색소(HbAlc) (r=0.15, P<0.01); ALT와 HbAlc (r=0.20, P<0.01), 모든 변수는 양의 상관관계를 나타났으며, De Ritis ratio는 글루코스 (r=-0.20, P<0.01)와 당화혈색소 (r=-0.14, P<0.01)와 음의 상관관계를 보였다. AST와 ALT 그리고 De Ritis ratio 를 독립변수로 하고 글루코스 (R²=0.05) 와 HbA1c (R²=0.04) 를 종속변수로 하여 회귀분석한 결과 독립변수는 종속변수에 통계적으로 유의하게 영향을 나타내는 것으로 나타났다. AST는 ALT 보다 혈당과 당화혈색소에서 상관관계가 낮게 나타났으며, ALT가 증가하는 것은 즉, De Ritis ratio 감소의 원인이 된다. 따라서, De Ritis ratio는 당뇨관련 검사와의 관계에서 의미가 있는 것으로 볼 수 있다.

The purpose of this study was to examine the effect of supplementary highly purified chitosan (HPC) on blood alcohol concentration in healthy human. The human study was performed with two sections. Each section of the study was conducted by two-phase cross-over design with a week wash-out period. All volunteers took HPC in one phase, and took a placebo in the next phase. Blood alcohol concentrations were different between in those taking HPC and in those taking the placebo in the human. And the concentration of serum aspartate aminotransferase (AST, GOT) and alanine aminotransferase (ALT, GPT), the indicator of liver cell damage, was lowered in those taking HPC, compared to those taking the placebo. In conclusion, taking HPC prior to drinking alcohol can somewhat reduce alcohol concentration in human blood and liver cell damage.

This paper presents a portable and compact optical device which can conveniently be used to perform a functional analysis of human liver function. The proposed system employed red/green LEDs, as a light source, and CMOS image sensor, which is commonly used in cellular phones. With this system, several blood serum samples have been evaluated for liver functional analysis by measuring light absorption level through the blood serum samples depending on aspartate aminotransferase (AST), alanine aminotransferase (ALT), and total bilirubin concentration. The light absorption through the blood serum samples containing AST, ALT, or total bilirubin can provide their concentrations. The green light absorption is more sensitive to the concentration of AST or ALT, and the red light absorption is more sensitive to the total bilirubuin concentration. Additional calibration steps were performed by using a MATLAB program in order to eliminate the light scattering effects from the extraneous particles existing in each blood serum sample. From the blind test, three standard light intensity curves through each enzyme have been obtained and the enzyme concentration values have been compared to those obtained from a commercially available biochemistry analyzer (Toshiba 200 FR). The average percent difference in the obtained concentrations from two systems for AST, ALT, and total bilirubin concentration came out to be 7.79%, 7.98%. and 7.56%, respectively, with the adjusted coefficient of determination (R2) higher than 0.98. This system can possibly lead to a low-cost and simple system that can be used as a point-of-care (POC) system in a condition without advanced equipments.

이 증례는 드물게 보는 경우로 simvastatin과 gemfibrozil을 오랫동안 함께 복용했음에도, 특이한 문제가 발현되지 않았지만, 이들을 warfarin와 함께 치료하는 경우, 아주 높은 alanine aminotransferase (ALT), aspartate aminotransferase(AST) 혈중 농도, rhabdomyolysis, 급성 신장 장애가 발생하였다. 그 후, Simvastatin와 gemfibrozil을 복용 중단시켰더니, ALT/AST는 빠르게 정상수치로 돌아온 경우이다. 이 증례 보고서는 의료인들에게 simvastatin과 gemfibrozil을 함께 혹은 따로 warfarin과 함께 복용시켜 치료할 경우, creatine phosphokinase (CPK) 와 creatinine 혈중 수치들을 포함하여 ALT/AST 농도들을 주의 깊게 모니터하도록 경각심을 주고자 한다.

이 증례는 알코올 중독증을 앓은 병력을 가졌으나 간 기능에 특이한 증후가 없던 환자가, 지역 사회 획득성 폐렴으로부터 유발된 중증 패혈증 치료를 받기 위해서 linezolid, moxifloxacin 과 함께 aztreonam을 초회 정맥주사 맞은 후, 아주 높은 수치의 alanine aminotransferase (ALT), aspartate aminotransferase (AST) 혈중 농도가 검출된 경우이다. 후속 치료에서 상기 3가지 항생제 대신 vancomycin과 ceftazidime을 주사했더니, ALT/AST가 빠르게 정상화됨이 관찰되었다. 이 증례 보고는 linzolid, moxifloxacin과 aztreonam을 함께 사용할 경우, 각별한 주의 관찰이 필요하며, 알코올 중독증을 앓은 병력을 가진 환자에게 투여 시 특별한 주의와 함께 AST/ALT혈중 수치를 검사토록 권하기 위한 것이다.

The purpose of this study was to probe the influences of NaF oral administration on a dose-effect relationship between fluoride levels of serum enzyme activity such as alkaline phosphatase (ALP), aspartate aminotransferase (AST), alanine aminotransferase (ALT), and lactate dehydrogenase (LDH) in rats fed experimental diets for 5 weeks. All groups increased the activity of serum ALP, AST, ALT, and LDH levels with increasing NaF. In addition the fluoride levels of serum and organ tissues (liver, brain, heart, lung, kidney) in oral NaF groups (NF3~NF50) were significantly increased by adding sodium fluoride in comparison with normal diet group (ND) (p<0.05). These results, a high concentration of sodium fluoride was determined that the toxicity to various organ tissues.

Biochemical tests such as aspartate aminotransferase (AST) and alanine aminotransferase (ALT) are useful for diagnosing patients with liver disease. In this study, we tested the association between copy number variation and the hepatic biomarkers AST and ALT based on 8,842 samples from population-based cohorts in Korea. We used Affymetrix Genome-Wide Human 5.0 arrays and identified 10,534 CNVs using HelixTree software. Of the CNVs tested using univariate linear regression, 100 CNVs were significant for AST and 16 were significant for ALT (P < 0.05). We identified 39 genes located within the CNV regions. DKK1 and HS3ST3B1 were shown to play roles in heparan sulfate biosynthesis and the Wnt signaling pathway, respectively. NAF1 and NPY1R were associated with glycoprotein processes and neuropeptide Y receptor activity based on GO categories. PTER, SOX14 and TM7SF4 were expressed in liver. DPYS and CTSC were found to be associated with dihydropyrimidinuria and Papillon-Lefevre syndrome phenotypes using OMIM. NPY5R was found to be associated with dyslipidemia using the Genetic Association Database.
