천고마비의 계절, 하늘은 높고 말은 살찐다는 가을이다. 가을이 되면 유난히 왕성해지는 식욕 때문에 다이어트에 어려움을 겪은 사림들이 많다. 이처럼 가을에 식욕이 늘어나는 이유는 기온 변화에 따른 신체의 반응 때문이다. 기온이 떨어지면 우리 몸은 체온을 유지하기 위해 기초 대사량이 5% 정도 증가하고, 활동하기 좋은 기온이라 상대적으로 활동량이 증가하면서 공복감을 빨리 느끼게 된다. 또, 추운 겨울을 대비해 우리 몸이 본능적으로 체지방을 늘리기 위해 식욕이 증가하기도 한다.

Backgrounds/Aims: Majority of intrahepatic stones found in Korean patients is calcium bilirubinate stone. However, reports defining cholesterol content of intrahepatic stones are rare. This study was conducted to analyze cholesterol content of intrahepatic stone quantitatively and to define its clinical significance. Methods: Chemical assay and supplementary FTIR (Fourier-transform infrared spectroscope) analysis were performed for cholesterol quantification of intrahepatic stones harvested from 89 consecutive patients by choledochoscope. Results: Intrahepatic stones were grouped by gross appearance and there were 3 cholesterol stones, 2 black stones, and 84 brown stones. Chemical assay disclosed that calcium bilirubinate stones (less than 50% cholesterol) were 89.3% (n=75) of brown stones, and mixed cholesterol stones (50-70% cholesterol) were 10.7% (n=9). Cholesterol content of primary intrahepatic stones (25.9±2.5%) were slightly smaller than that of secondary intrahepatic stones (32.8±4.1%), but it could not reach statistical significance (p=0.135). There were no significant differences in chemical composition of intrahepatic stones according to clinical findings such as age, sex, body mass index, laboratory findings, and locations of stones. Conclusions: Intrahepatic stones found in Korean patients have considerably higher cholesterol content than expected by gross inspection. Investigation of the role of cholesterol metabolism in the pathogenesis of intrahepatic stone may be helpful to establish an appropriate strategy of treatment for intrahepatic stone.
