The effect of Red ginseng saponin on plasma lipid levels in Wistar rats fed on a diet high in cholesterol and triglyceride was determined. A dose of Red ginseng-crude saponin (150 mg/kg/day) was administered orally for 4 weeks to Wistar rats fed on a diet containing 2% cholesterol and 10% olive oil. Plasma levels of total cholesterol, HDL-cholesterol and triglyceride were measured and lipoproteins were analyzed by using electrophoretic technique. Red ginseng saponin showed no significant changes of HDL-cholesterol level but it lowered plasma levels of total cholesterol and elevate those of triglyceride intensively.

Blood lipid levels in rats with high fat-fed hyperlipemia were determined after intraperitoneal administration of a methanolic extract of Prunus davidiana Fr. stems. Administration of the methanolic extract for 6 days produced a significant decrease of blood triglyceride and total cholesterol, and the atherogenic index was also improved. In addition to the hypolipemic effect, the methanolic extract was also shown to be effective in reducing an elevated level of glucose in rats with hyperlipemia resulting from high-fat feeding. On the other hand, blood triglyceride and total cholesterol in rats fed with stock diet were not affected by administration of the methanolic extract even if there was a tendency to decrease. No significant change was also found in the level of glucose. Thus, it is suggested that this methanolic extract probably may increase the metabolic utilization only when fed with excess fat.

Chondroblastomas are rare entities accounting for approximately 1% of all primary bone tumors. We describe a case of a 7-year-old girl with a giant chondroblastoma of the maxilla, treated with bilateral class III maxillectomy and reconstruction with a double-barreled and double skin paddle fibular free flap. We show evidence of an excellent aesthetic outcome at 6 months' follow up with no evidence of tumor recurrence.

Circumcision is one of the most common rituals in Jewish and Islamic cultures. It may also be performed for phimosis correction or the treatment of recurrent balanitis. Although circumcision is considered to be a technically easy and safe surgical procedure with no significant risk, it may lead to severe complications such as necrotizing fasciitis or total penis amputation. In this report, we present a case of penis amputation at two levels occurring with third-degree burns due to electrocautery during circumcision. Although penile replantation was attempted, it was unsuccessful due to burn damage to the veins. After restoration of the functional structures, the penis was buried in the inguinal area by reepithelization to maintain blood circulation. The recovery of the penis was successful. This case is presented as a novel example of groin flap surgery to achieve a functionally and aesthetically acceptable outcome in a salvage operation for a penis with significant traumatic injury, which has not been previously reported in the literature.

Total auricular reconstruction with autogenous tissue remains one of the greatest technical challenges for reconstructive plastic surgeons because of the ear's complex morphology with delicately convoluted cartilages and very thin skin. In a successfully created ear, a natural three-dimensional illusion visualized from the patient's profile, frontal, and posterior views is crucial. Accordingly ear framework should have adequate lateral aspect as well as suitable frontal aspect even before being lifted to this purpose. For this goal, rib cartilage should be harvested from three-dimensionally adequate area. It is the most essential point in framework fabrication that the baseblock should have semi-cup curvature via multiple parallel cuts made on its medial surface. Between January 1999 and May 2003, we performed 29 cases of total ear reconstruction with autogenous rib cartilage graft using this scoring technique and obtained satisfactory results, which showed more natural appearance visualized from the patient's profile, frontal, and posterior views.

Second derivative (D2) spectrometry using ion-pair extraction technique was development for the determination of total glycyrrhetic acid (GA) in Glycyrrhizae Radix, Glycyr-rhizin (G) obtained from Glycyrrhizae Radix was hydrolyzed into GA in 2 N-HCI and methanol (1:1) and extracted from aqueous phase in the form of an ion-pair complex with tetrapentylammonium bromide (TPA) as a counter ion. Maximum D2 amplitude (Z value) was obtained when 1000-fold or greater molar ratio of TPA was used at pH 11. Reaction an effective extraction solvent of the ion-pair complex. The linearity of standard curve of ion-pair GA was obtained in the range of 4.120 $\mu$g/ml as GA. Assayed contents of GA in dry powder by D2 UV spectrometry and HPLC method were 5.31 $\pm$ 0.04% and 5.20 $\pm$ 0.008%, respectively.

This study was undertaken to investigate the hypocholesterolemic activity of Bifidobacteria (B. breve K-110, B. breve K-111, and B. infantis K-525) isolated from a healthy Korean. The administration of B. breve K-110 and K-111 with a high cholesterol diet significantly protected the increase of serum total cholesterol and LDL cholesterol relative to that of a high cholesterol diet alone. Such a diet supplemented with 0.5％ B. breve K-111 decreased serum total cholesterol and LDL cholesterol to 57 and 55％, respectively. The administration of Bifidobacteria also significantly inhibited the lipid-deposited surface in the aorta. The normalizing activity of serum cholesterol level in cholesterolemic rats was accelerated by Bifidobacteria. The normalizing activity of B. breve K-111 on serum cholesterol level was superior to that of B. breve K-110. These results suggest that Bifidobacteria in the human intestine playa role in the prophylactics of arteriosclerosis.

The total synthesis of a demethoxy-egonol isolated from Styrax obassia, 5-(3-hydroxypropyl)-2-(3',4'-methylenedioxyphenyl)benzofuran (9), is described. The key steps involve the construction of a 2-arylbenzofuran skeleton 7 from methyl 3-(4-hydroxyphenyl)propionate with 2-chloro-2-methylthio-(3',4'-methylenedioxy) acetophenone (6) in the presence of ZnCl$_2$ and successive desulfurization of the resulting product 7.

We investigated the effects of n-alkanols on the range and rate of the lateral diffusion of 1, 3-di(1-pyrenyl)propane in the model membranes of total phospholipid fraction extracted from synaptosomal plasma membrane vesicles. n-Akanols increased the range and rate of the lateral diffusion of 1, 3-di(1-pyrenyl)propane in the bulk model membrane structures (inner + outer monolayers) and the potencies of n-alknols up to 1-nonanol increased by 1 order of magnitude as the carbon chain length increases by two carbon atoms. The cut-off phenomenon was reached at 1-decanol, where further icnrease in hydrocarbon length resulted in a decrease in the lateral diffusion. However, significant changes in the 1'/1 value were not observed by methanol (from 100 to 2500 mM), ethanol (from 25 to 800 mM), and 1-propanol (from 10 to 250 mM) over entire concentration.

Since reactive oxygen species (ROS) and hydroxyl radicals ($^-OH$) play an important role in the pathogenesis of many human degenerative diseases, much attention has focused on the development of safe and effective antioxidants. Preliminary experiments have revealed that the methanol (MeOH) extract of the stem of Prunus davidiana exerts inhibitory/scavenging activities on 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radicals, total ROS and peroxynitrites ($ONOO^-$). In the present study, the antioxidant activities of this MeOH extract and the organic solvent-soluble fractions, dichloromethane (CH$_2$Cl$_2$), ethyl acetate (EtOAc), and n-butanol (n-BuOH), and the water layer of P. davidiana stem were evaluated for the potential to inhibit $^-OH$ and total ROS generation in kidney homogenates using 2',7'-dichlorodihydrofluorescein diacetate (DCHF-DA), and for the potential to scavenge authentic $ONOO^-$. We also evaluated the inhibitory activity of seven flavonoids isolated from P. davidiana stem, kaempferol, kaempferol 7-Ο-$\beta$-D-glucoside, (+)-catechin, dihydrokaempferol, hesperetin 5-Ο-$\beta$-D-glucoside, naringenin and its 7-Ο-$\beta$-D-glucoside, on the total ROS, $^-OH$ and $ONOO^-$ systems. For the further elucidation of the structure-inhibitory activity relationship of flavonoids on total ROS and 'OH generation, we measured the antioxidant activity of sixteen flavonoids available, including three active flavonoids isolated from P. davidiana, on the total ROS and 'OH systems. We found that the inhibitory activity on total ROS generation increases in strength with more numerous hydroxyl groups on their structures. Also, the presence of an ortho-hydroxyl group, whether on the Aring or S-ring, and a 3-hydroxyl group on the C-ring increased the inhibitory activity on both total ROS and $^-OH$ generation.
