A method and apparatus for manufacturing an edible film are disclosed. The method includes a plurality of applying operations of applying solution for forming the edible film onto lower wrapping paper in a thin film shape. The solution-applying operations include a first solution-applying and a second solution-applying operation. Therefore, in the case of an edible medicine film product, particularly, when a tiny dosage of medicine must be loaded onto an edible medicine film, a loss of medicine can be reduced as much as possible. A variety of kinds of films can be manufactured through a multi-solution-applying operation, when different kinds of medicines, for example, those which are respectively absorbed in the mouth mucous membrane, the stomach and the intestine, are required.

This study examined the effect of fermentation on the ability of antler to act as a stimulator of hematopoietic activity. Hemolytic anemia was induced by phenylhydrazine (PHZ) in female Sprague-Dawley rats. The vehicle or antler extract (nonfermented or fermented) mixed in drinking water was administered from Days 2 to 15 after PHZ injection. On Day 15, red blood cell counts in the fermented antler group (6.33×106/μL) were significantly higher than those in the nonfermented antler group (5.90×10 6/μL) (P<.05), and rats treated with fermented antler extract tended to have higher hemoglobin compared with rats treated with nonfermented antler extract, but not significantly. In addition, rats treated with fermented antler extract had slightly lower serum erythropoietin levels compared with nonfermented antler extract, which were not statistically different from serum erythropoietin levels of nonanemic rats. We conclude therefore that the hematopoietic activity of antler might be increased by the fermentation process. © Copyright 2012, Mary Ann Liebert, Inc. and Korean Society of Food Science and Nutrition 2012.

This study aimed to evaluate the potential of -cedrene as a new anti-obesity drug by characterizing absorption, metabolism and pharmacokinetics in rats. -Cedrene was administered intravenously (10 and 20 mg/kg) and orally (50 and 100 mg/kg) to female and male Sprague-Dawley rats. Blood, tissues, urine, and feces were collected at predetermined times. -Cedrene concentrations were determined by a validated gas chromatography-tandem mass spectrometry (GC-MS/MS). A gas chromatography-mass selective detection (GC-MSD) method was used to identify the major metabolite. After i.v. injection, -cedrene exhibited a rapid clearance (98.4-120.3 ml/min/kg), a large distribution volume (35.9-56.5 l/kg), and a relatively long half-life (4.0-6.4 h). Upon oral administration, it was slowly absorbed (Tmax = 4.4 h) with bioavailability of 48.7-84.8%. No gender differences were found in its pharmacokinetics. Upon oral administration, -cedrene was highly distributed to tissues, with the tissue-to-plasma partition coefficients (Kp) far greater than unity for all tissues. In particular, its distribution to lipid was notably high (Kp = 132.0) compared to other tissues. A mono-hydroxylated metabolite was identified as a preliminary metabolite in rat plasma. These results suggest that -cedrene has the favorable pharmacokinetic characteristics to be further tested as an anti-obesity drug in clinical studies.

The aim of this study is to evaluate the effect of spent coffee ground (SCG) ethanol extract on UVB-induced skin aging in hairless mice. An ethanol extract of SCG (ESCG) was prepared using the residue remaining after extraction of oil from roasted SCG. High performance liquid chromatography (HPLC) analysis showed that the content of caffeine (41.58 ± 0.54 μg/mg) was higher than that of chlorogenic acid isomers (~ 9.17 μg/mg) in ESCG. ESCG significantly decreased the UVB-induced intracellular reactive oxygen species in HaCaT cells. UVB-induced wrinkle formation in mice dorsal skin was effectively reduced by ESCG administration; high dose of ESCG (5 g/L) caused the reduction of wrinkle area by 30% compared with UVB-treated control (UVBC). This result correlated with the ESCG-mediated decrease in epidermis thickness (25%). In addition, ESCG administration significantly reduced transdermal water loss (20%) and erythema formation (35%) derived from UVB exposure. Collagen type I (COL-1) level in dorsal skin was effectively recovered by ESCG administration. These results were supported by down-regulation of collagen-degrading matrix metalloproteinase 2 (MMP2) and 9 (MMP9) expressions. Our results indicate that ESCG protects mouse skin from UVB-induced photoaging by suppressing the expression of matrix metalloproteinases. Our study suggests that ESCG may be anti-photoaging agent. © 2015 Published by Elsevier B.V.

Background Although the health effects of vitamin C are well known, its physiological effect on serum lipoproteins and microRNA still remain to be investigated, especially daily consumption of a high dosage. Objectives To investigate the physiological effect of vitamin C on serum lipoprotein metabolism in terms of its anti-oxidant and anti-glycation activities, and gene expression via microRNA regulation. Methods We analyzed blood parameters and lipoprotein parameters in young subjects (n = 46, 22 ± 2 years old) including smokers who consumed a high dose of vitamin C (1250 mg) daily for 8 weeks. Results Antioxidant activity of serum was enhanced with the elevation of Vit C content in plasma during 8 weeks consumption. In the LDL fraction, the apo-B48 band disappeared at 8 weeks post-consumption in all subjects. In the HDL fraction, apoA-I expression was enhanced by 20% at 8 weeks, especially in male smokers. In the lipoprotein fraction, all subjects showed significantly reduced contents of advanced glycated end products and reactive oxygen species (ROS). Triglyceride (TG) contents in each LDL and HDL fraction were significantly reduced in all groups following the Vit C consumption, suggesting that the lipoprotein was changed to be more anti-inflammatory and atherogenic properties. Phagocytosis of LDL, which was purified from each individual, into macrophages was significantly reduced at 8-weeks post-consumption of vitamin C. Anti-inflammatory and anti-senescence effects of HDL from all subjects were enhanced after the 8-weeks consumption. The expression level of microRNA 155 in HDL3 was reduced by 49% and 75% in non-smokers and smokers, respectively. Conclusion The daily consumption of a high dose of vitamin C for 8 weeks resulted in enhanced anti-senescence and anti-atherosclerotic effects via an improvement of lipoprotein parameters and microRNA expression through anti-oxidation and anti-glycation, especially in smokers. © The Royal Society of Chemistry.

A new series of 3-allylthio-6-(mono or disubstituted) aminopyridazines was synthesized by reacting 3-allylthio-6-chloropyridazine with several amines to develop new anticancer agents. These new compounds showed antiproliferative activities against lung cancer (A549), hepatoblastoma (Hep3b), prostate cancer (PC3), colon cancer (SW480) and cervical cancer (HeLa) cells in MTT assays, and could be promising candidates for chemotherapy of carcinomas. Compound 5 (3-allylthio-6-homopiperidinylaminopyridazine) showed higher potencies than 5-FU for inhibiting the growth of these cell lines. This suggests the potential anticancer activity of compound 5. © 2010 The Pharmaceutical Society of Korea and Springer Netherlands.

Kyung-Ok-Ko (KOK), a well-known traditional Korean medicinal formula, has long been used to invigorate the essential qi. This use of KOK may be associated with reproductive ability as a more modern concept. The protective effect of KOK was evaluated against deterioration of testicular function induced by heat exposure in male mice. Male fertility was disrupted by scrotal heat stress at 43C for 5 weeks. KOK (0.25, 0.50, and 2.00g/kg/day) was administered orally at 3h after the stress. To evaluate the protective effect of KOK, body weight, testicular weight, sperm count, sperm motility, and histopathological changes in the testes were evaluated. KOK-treated mice significantly recovered their general health, as evidenced by body weight. KOK-treated mice also showed significantly higher testes weights, sperm counts, and sperm motility than did the heat stress group. KOK-treated mice significantly recovered the morphological appearance of the seminiferous tubules and seminiferous epithelium. Furthermore, KOK-treated mice significantly increased antioxidant enzyme activities and reduced the protein expressions of apoptosis in the testes. KOK significantly protects against heat-induced damage to testicular function in male mice by inhibiting oxidative stress and apoptosis, indicating that KOK may be an effective agent for treatment of heat-induced male infertility.

Hovenia dulcis Thunb. (HDT) was known to have anti-fatigue, anti-diabetes, neuroprotective, and hepatoprotective effects. In the present study, the anti-fatty liver mechanism of HDT was elucidated in oleic acid (OA)-treated Hep G2 cells and acute hyperlipidemia mouse model using Triton WR-1339. Here, HDT activated p-AMP-activated protein kinase (p-AMPK), proliferator activated receptor-, carnitine palmitoyltransferase and also inhibited the expression of lipogenesis and cholesterol synthesis proteins, such as 3-hydroxy-3-methylglutaryl-CoA reductase, sterol regulatory element binding protein-1c, SREBP-2, and fatty acid synthase in OA-treated Hep G2 cells. Conversely, AMPK inhibitor compound C blocked the anti-fatty liver effect of HDT to induce AMPK phosphorylation and decrease 3-hydroxy-3-methylglutaryl-CoA reductase and lipid accumulation by oil red O staining in OA-treated Hep G2 cells. Additionally, HDT pretreatment protected against the increase of serum total cholesterol, triglyceride, low-density lipoprotein cholesterol and phospholipid in an acute hyperlipidemia mouse model with enhancement of glutathione reductase, glutathione peroxidase, superoxide dismutase, and catalase activities. Taken together, HDT inhibits OA-induced hepatic lipid accumulation via activation of AMPK and proliferator activated receptor-/carnitine palmitoyltransferase signaling and enhancement of antioxidant activity as a potent candidate for nonalcoholic fatty liver disease and hyperlipidemia.
