  • 80% extract of Gamigwaruhaebaekbaekju-Tang (GGHBT), Gagamgwaruhaebaekbaekju-Tang (GGGHBT) and Gamigwaruhaebaekwhanggum-Tang (GGHWT) remarkably showed inhibitory effects on HMG-CoA reductase, lipid peroxidation of rat liver and LDL oxidation, and DPPH free radical scavenging effect in a dose-dependent manner. Especially, GGHWT which is formulated with Trichosanthis Fructus, Pinelliae Tuber, Aurantii Immatures Fructus, Magnoliae Cortex, Allii Macrostemi Bulbus, Cinnamomi Ramulus and Scutellariae Radix on the basis of Gwaruhaebaekbaekiu-Tang listed on the traditional medicinal references showed more effective hypocholesterolemic activities in vitro bioassay than the other prescriptions.

  • Kamiondamtang(KODT) has been used in oriental medicine as stress by many medical practitioner for the study of KODT, we had fed mice divided to three groups(basal diet, hyperlipidemic diet, hyperlipidemic diet + KODT), and observed the change of weight, total cholesterol, triglyceride, SGOT, SGPT, HDL-cholesterol, LDL-cholesterol on the serum per every 7days for 6weeks. To help comparison with the results above, we had tested endothelial cells and liver. The results of this Study were obtained as fallows ; 1. Total cholesterol, triglyceride and LDL-cholesterol were decreased significantly by KODT. 2. HDL-cholesterol was increasd significantly by KODT. 3. SGOT was intended to decrease by KODT, 4. %W was decreased significantly by KODT. 5. In case of supplying KODT, WBC attatched on endothelial cells and vacuoles in muscular layer were not observed. 6. In case of supplying KODT, fatty degeneration was not observed in liver portal area.

  • This study investigates the effects of Psidium guajava L. leaf (Pg), Lagerstroemia speciosa L. leaf (Ls) and mixture A (Pg, Ls, Morus indica L. leaf extract, Pinus densiflora needles extract, Acanthopanax senticosus M. root extract) on streptozotocin (STZ)-diabetes rats. For four weeks, STZ-diabetes rats were fed crystallized extracts of Pg, Ls, and mixture A. Compared to the diabetic control group, extracts of Pg, Ls, and mixture A decreased glucose levels in rats by 20%, 14% and 24% respectively. These extracts also decreased the level of total cholesterol, triglyceride and free fatty acid, compared to the diabetic control group, while effectively increasing levels of insulin and high-density lipoprotein-cholesterol. These results showed that mixture A had greater antihyperglycemic, antihyperlipidemic, and insulin-increasing effects than the Pg and Ls extracts. Mixture A also showed better restoration of damaged beta cell function compared to Pg and Ls extracts. Therefore, it was proved that mixture A provides a beneficial synergistic effect when compared with Pg and Ls extracts used individually.

Effect of the Seaweed (Monostroma nitidum) Extract on Triton WR-1339 Induced Hyperlipidemia in Mouse (Triton WR-1339 복강주사로 유도된 생쥐의 고지혈증에 대한 참홑파래 추출물의 영향)

  • An antihyperlipidemic effect was observed by intraperitoneal injection of the seaweed Monostroma nitidum extract. Hyperlipidemia was induced by intraperitoneal injection of Triton WR-1339 $(60\;{\mu}g/g-body\;weight)$ into a mouse. Maximum level of blood cholesterol was reached at 20 hours after Triton injection. By simultaneous injection of the M. nitidum extract $(30\;{\mu}g/g-body\;weight)$ with the Triton into each right and left sides of the peritoneal cavity, levels of total cholesterol and low density lipoprotein were decreased to $24\%\;and\;14\%$ compared to Triton injection only. For histochemical changes, hepatic tissues obtained at 40 hours after injection of the Triton and the M. nitidum extract were fixed in fromol-calcium solution. The meshlike cytoplasms disappeared and hapatic plates were recovered in mice injected with the M. nitidum extract. Numbers of lipid drops and cholesterol particles also decreased in the portal space of the hepatic cytoplasm. This indicates that the accumulation of lipid, including cholesterol, caused by Triton was prevented by the antihyperlipidemic effect of extract from the seaweed M. nitidum.

  • After Triton WR-1339 (TX; 600mg/kg) intraperitoneal injection, hepatic tissues of ICR mice were intragastric injected with Hyulboochucketang extract(HCE; 3.3ml/kg/day) were observed to investigate the suppressive effect of lipid accumulation that evoke by the antihyperlipidemic effect of HCE. These hepatic tissues were fixed in fromol-calcium solution and were cryocut. These tissues stained by H&E for general morphology, sudan black B for lipid and perchloric acid-naphthoquinone(PAN) method for cholesterol. After TX treatment, the increase of hepatocyte having meshlike cytoplasm(HHMC) were shown in all hepatic lobules and the hepatic plates were disappeared in the aggregative region of HHMC. The number of blue black colored lipid drop and dark green colored asterisk shaped cholesterol particle in hepatic cytoplasm were increased and the size of lipid drop and cholesterol particle were enlarged. But, in HCE-treated mice, the HHCM were disappeared and hapatic plate were rearranged. The number of lipid drop and cholesterol particle were decreased than TX-treated mice and the size of lipid drop and cholesterol particle were diminished. As results indicated that the HCE work on the suppression of lipid accumulation in hepatic tissue of hyperlipidemic mice caused by disturbance of lipid metabolism.

  • The aim of the present study was to evaluate the possible roles of hyperforin against hyperglycemia, hyperlipidemia and oxidative stress in streptozotocin-induced diabetic rats. Diabetes was induced by a single intraperitoneal injection of streptozotocin (65 mg/kg). Biochemical parameters were measured following hyperforin treatment (10 mg/kg, i.p.) for 7 days. Hyperforin treatment significantly reversed the elevations in plasma glucose, triglycerides, total cholesterol and LDL-cholesterol. Hyperforin also reversed the declines in plasma HDL-cholesterol and liver glycogen, but did not reverse the change in plasma insulin levels when compared to the diabetic control rats. Hyperforin treatment also reversed the oxidative stress induced by streptozotocin. Moreover, the effect of the hyperforin on peripheral glucose utilization in normal rats was evaluated by an oral glucose tolerance test (OGTT). Hyperforin treatment significantly increased (p < 0.05) the glucose tolerance compared to the vehicle in OGTT. The antihyperglycemic, antihyperlipidemic and antioxidant activities of hyperforin (10 mg/kg, i.p.) were comparable qualitatively to glibenclamide (1 mg/kg, p.o.). In conclusion, we report for the first time through an in vivo study that hyperforin is potentially valuable for the treatment of diabetes and its associated hyperlipidemia and oxidative stress by enhancing the glucose utilization by peripheral tissues such as muscle and adipose tissues.
