Effect of clofibrate on postheparin plasma triglyceride lipase activities in patients with hypertriglyceridemia

Metabolism: Clinical and Experimental
E A NikkilaC Ehnholm


The lipoprotein lipase (LPL) and hepatic triglyceride lipase (HL) activities of postheparin plasma were determined by a specific immunochemical method in 17 patients with primary hyperlipoproteinemia before and during treatment with clofibrate. The drug caused a significant reduction of serum cholesterol (11%) and triglyceride (45%) levels. Postheparin plasma LPL activity rose in all subjects, the average change being 46% (p less than 0.001). The increase of LPL was positively correlated to the pretreatment LPL activity. There was no correlation between the serum triglyceride concentration and postheparin LPL activity either before or during clofibrate administration. On the other hand, in the clofibrate responders there was a weak correlation between the relative changes of triglyceride concentration and LPL activity (r = 0.43, p less than 0.05). During clofibrate treatment the LPL activity of the hypertriglyceridemic patients was significantly higher than the corresponding value of untreated healthy normoglyceridemic subjects of similar age. The postheparin plasma HL activity was not influenced by clofibrate.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Synthetic Genetic Array Analysis

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.
