This study was designed to investigate the effects KH-204 on erectile dysfunction in hyperlipidemic rat. KH-204 has been evaluated antihyperlipidemic and antierectile dysfunction effects on experimental hyperlipidemic rats induced by high fat diet. After oral administration of the water extract KH-204 (50, 100, 200, 300 mg/kg) to hyperlipidemic rats for 8 weeks, the variables including body weight, total cholesterol, HDL and LDL levels in serum, the expression of eNOS and nNOS in penis were measured. And erectile function was determined by measurement of intracavernosal pressure (ICP) and maximal arterial pressure (MAP) after electrical stimulation of the cavernosal nerve. Oral administration of KH-204 significantly inhibited the increases of serum total cholesterol and LDL-cholesterol levels and the decreased of serum HDL-cholesterol levels in hyperlipidemic rats induced by high fat diet. The penile expression level of the two enzyme (eNOS, nNOS) were increased significantly after oral administration of the KH-204 50 mg/kg. Erectile function after 10 volts stimulation was significantly decreased in the hyperlipidemic rat compared with the normal rat, but increased in KH-204 group compared with hyperlipidemic group. These results suggest that KH-204 is effective for erectile dysfunction in hyperlipidemia.

This study was designed to investigate effects of KH-305 on erectile dysfunction in hyperlipidemic rat. KH-305 has been evaluated for antihyperlipidemic and antierectile dysfunction effects on experimental hyperlipidemic rats induced by high cholesterol-diet. After oral administration of KH-305 water extract (50, 100, 200, 300 mg/kg) to hyperlipidemic rats for 8 weeks, the variables including body weight, total cholesterol, HDL-, and LDL-cholesterol levels in serum, the expression of eNOS and nNOS in penis were measured. Also, erectile function was determined by the measurements of intracavernosal pressure (ICP) and maximal arterial pressure (MAP) after electrical stimulation of the cavernosal nerve. Oral administration of KH-305 extracts significantly inhibited the increase of serum total cholesterol and LDL-cholesterol levels and the decrease of serum HDL-cholesterol level in hyperlipidemic rats induced by high fat diet. The penile expression level of the two enzymes (eNOS, nNOS) were increased significantly after oral administration of the KH-305 extracts. Erectile function after 10 volts stimulation was significantly decreased in the hyperlipidemic rat compared with the normal rat, but increased in KH-305 group compared with hyperlipidemic group. These results suggest that KH-305 is effective for erectile dysfunction in hyperipidemia.

Objectives : We studied Effects of Hagocho(prunella vulgaris L.), Gamgook(chrysanthemum indicum L.) and Galgeun(pueraria Radix) aqua-acupuncture on the hyperlipidemic rat. methods : We investigated lowering lipid effect, oxidative capacity, concentration of TNF-${\alpha}$, IL-6, Leptin and histological consideration in hyperlipidemic rat. Forty male Sprague-Dawley rats weighing about 400g were divided into 5 groups of control, Ⅰ: Hagocho (prunella vulgaris L.)+Gamgook (chrysanthemum indicum L.) and Gokji aqua-acupuncture, Ⅱ: Hagocho(prunella vulgaris L.)+Gamgook (chrysanthemum indicum L.) and Joksamri aqua-acupuncture, Ⅲ: Hagocho(prunella vulgaris L.)+Galgeun(pueraria Radix)and Gokji aqua-acupuncture and Ⅳ: Hagocho (prunella vulgaris L.)+Galgeun(pueraria Radix) and Joksamri aqua-acupuncture. Results : Contents of plasma ${\beta}$-lipoprotein, contents of IL-6, TNF-${\alpha}$ and leptin, Plasma triglyceride and glucose, plasma total cholesterol and LDL-cholesterol, liver total cholesterol, liver triglyceride, plasma and liver TBARS, free fatty acids showed a tendency to decrease in the aqua-acupuncture groups compared to those of control group. The activities of GOT and GPT showed no significantly different in all treatment groups. Values of super oxide dismutase, glutathione peroxidase and catalase activity showed a tendency to increase in the aqua-acupuncture groups. Histological consideration of heart, kidney and liver in the aqua-acupuncture groups showed slight vasodilation and fat accumulation compared to those of normal rat. Conclusions : These results indicated that prunella vulgaris L., chrysanthemum indicum L. and pueraria Radix aqua-acupuncture at gokji(LI11) and Joksamri(ST36) suppressed adipose tissue mass and lipid peroxidation and increased antioxidant system in hyperlipidemic rat.

The anti-hyperlipidemic effects of an ethyl acetate fraction from Orostachy japonicus in a high lipid diet-induced hyperlipidemic rat model were assessed. The fraction, which contained kaempferol, astragalin, and isoquercitrin, was associated with significant weight loss and reduction of lipid contents in serum and liver tissues. The fraction, which contains mainly flavonoids, diminished the levels of malondialdehyde and hydroxyl radical, and increased the anti-oxidative enzyme activities of superoxide dismutase, catalase, and glutathione peroxidase. Reduced bleeding and plasma clotting times resulting from the administration of the ethyl acetate fraction may reduce cardiovascular disease associated with hyperlipidemia.

Development of hyperlipidemic animal model is prerequisite for the screening of drugs lowering the blood lipoprotein level. In this study, two kinds of diet regimens were tried for the hyperlipidemic effect. The model will be used for the screening of current prescriptions to a variety of diseases related to hyperlipidemia by practioner of traditional herbal medicine. Fifteen male Wister rats of 200g were divided into three groups, and given normal, or either one of the two high cholesterol diets for up to 2 weeks. Regimen HC-1 and regimen HC-2 contained I% and 2% cholesterol in diet, respectively. Total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL) and lower density lipoprotein cholesterol (LDL) levels in the serum were measured before the start of the diet, at 1 week after the start, and at 2 week point. Both regimens resulted in hyperlipidemia with the typical characteristics of increase in TC and LDL, and reduction in HDL, and showed no observable side effects such as diarrhea. In conclusion, both of HC-1 and HC-2 regimens appeared appropriate as diet regimens for the hyperlipidemic rat model.

Accumulating evidence indicates that lactic acid bacteria could improve host physiology and lipid metabolism. To investigate the effect of the gut microbiota on host lipid metabolism, a hyperlipidemic rat model was established by feeding rats a high-fat diet for 28 days, and the gut microbiota of the rats was analyzed using real-time PCR before and after administration of Lactobacillus rhamnosus hsryfm 1301 and its fermented milk for 28 days. The findings showed that the Lactobacillus spp., Bifidobacterium spp., Bacteroides spp., and Enterococcus spp. content in the hyperlipidemic rats gut was increased significantly (p < 0.05), while the Clostridium leptum and Enterobacter spp. content was decreased significantly after intervening with L. rhamnosus hrsyfm 1301 and its fermented milk for 28 days (p < 0.05). Furthermore, the lipid levels of the serum and the liver were decreased significantly (p < 0.05) and the fecal water content was increased significantly (p < 0.05) in the hyperlipidemic rats after the intervention, and hepatocyte fatty degeneration of liver tissues was also prevented. A positive correlation was observed between the Clostridium leptum content and the level of serum cholesterol, triglycerides, low-density lipoprotein, and high-density lipoprotein, and a negative correlation was observed between the Enterobacter spp. content and the Lactobacillus spp. and Bifidobacterium spp. content in the hyperlipidemic rats gut. These results suggest that the gut microbiota and lipid metabolism of hyperlipidemic rats could be improved by supplementation with L. rhamnosus hsryfm 1301 and its fermented milk.
