OBJECTIVE: To study the influence of Jiangzhining decoction on the genetic expression of Liver LDLR of the rats suffered from hyperlipemia. METHOD: Laboratory animals were male wister rats with hyperlipemia resulting from high fat feeding. Prescription was the douche of stomach with Jiangzhining decoction (200%) with a dosage of 1.4 g.kg-1, for 15 successive days. Total RNA was extracted from the liver tissue of treated rats and LDLRmRNA was detected by Dot blot hybridization. Expression levels of LDLRmRNA was estimated by a ratio of LDLRmRNA and beta-actin mRNA. RESULT: The difference between expression levels of LDLRmRNA for normal group and those for hyperlipemia group (100% +/- 19% vs 39% +/- 14%) was significant (P < 0.05); and the difference between decoction group (108 +/- 8%) and hyperlipimia group was also highly significant (P < 0.01). CONCLUSION: High fat feeding reduces the expression of liver LDLRmRNA while the decoction can greatly increase it. The study and development of Jiangzhining are significant in preventing and curing cadiocerebral diseases.
