- Triglycerides and phospholipids 0.5-2mg (wet weight) of human liver material obtained by the fine-needle aspiration biopsy technique can be estimated after chloroform:methanol extraction by the determination of lipid phosphorus and glyceride glycerol. The methods are based on the colorimetric determination of inorganic phosphate after oxidation of the phospholipids and the enzymatic fluorometric determination of glycerol after complete hydrolysis of the triglycerides, catalyzed by purified pancreatic lipase. The accumulation of lipids is then expressed as the increase in the molar ratio of triglycerides over phospholipids.

- Three healthy young male subjects were given a single load of ethanol (approximately 3 g/kg body weight) over 5 hours. Liver aspiration biopsies were performed at the start of the experiment and 6, 14, 24, and 48 hours after the start. Blood alcohol and serum transaminase activity levels were measured simultaneously. Triglycerides and phospholipids of the liver biopsy material were determined by a previously described method. The increase of the molar ratio triglycerides over phospholipids (TG/PL) was used to express triglyceride accumulation in the livers. At 24 hours from the start of the experiment this ratio had increased 2-5 times, and then declined to almost the initial values at 48 hours. Serum transaminases showed a slight increase over the entire experimental period. Considerable individual variation in the parameters was found. The results show that it is possible to follow time-course of rapid metabolic changes in the human liver by a combination of the fine-needle aspiration biopsy technique and biochemical micro-methods.
