  • This study aimed to examine the treatment effect of Muraenesox cinereus extract product combined with high frequency on men's damaged skin. The subjects were treated by a product containing M. cinereus extract combined with high frequency therapy for six weeks and tested in skin condition. First, for moisture level change, there was no significant difference between the control group treated only by high frequency therapy and the experimental group treated by a M. cinereus extract product combined with high frequency therapy. But the subjects who increased consistently in moisture level in the cheek and chin were more common in the experimental group. Second, for an oil level, prominently high increase was found in both the control group and the experimental group. Finally, for a rough level, while there was little difference in the control group between immediately after peeling and after six weeks, high improvement effect on a curve was found in the experimental group. Based on this result, cosmetics using M. cinereus extract may have a positive effect on men's skin which is exposed to several stress factors. Accordingly, this result will contribute to developing men's functional cosmetics.

  • This study investigated the effects to lowering hyperlipidemic levels in hamsters by feeding them naringin and onion extracts. The hyperlipidemic levels on all of the hamsters were raised by feeding them with high fat atherogenic diet (HFAD) containing 10% coconut oil and 0.05% cholesterol. The experimental groups were randomly assigned to 5 groups (normal, control, OEN, OES, and OESN) each 6 hamsters over a 40 days period. The control group (HFAD) received a 10% coconut oil and 0.05% cholesterol with basal diet, the OEN group which received an onion extract mixture contaning 50% water and 50% onion extract, the OES group which received 100% onion extract, the OESN group which received 100% onion extract combined with 1% naringin. Serum cholesterol and triglyceride levels significantly decreased in the naringin treated group while the HDL cholesterol level increased. On the other hand, the morphology of the mitochondria and nuclei found in the livers of the treated group given naringin were siginficantly different when compared to those group given high fat diets. In conclusion, onion extract with naringin decreased cholesterol levels in hamster's livers.

  • Recovery of aromatics in extract phase which was obtained by batch equilibrium extraction between light cycle oil(LCO) and dimethylsulfoxide(DMSO) solution as solvent was investigated by re-extraction. To select the most suitable re-extraction solvent for recovery of aromatics in extract phase, distribution equilibrium was measured between extract phase and solvents. The solvents used were benzene(B), toluene(T), m-Xylene(mX), n-hexane(Hx) and n-hexane(Hx) and n-Octane(Ot). From the distribution coefficients and yields of aromatics, Hx seemed to be the most suitable. Furthermore, effects of operation parameters for re-extraction of aromatics in the extract phase were studied by batch equilibrium re-extracion with Hx as solvent. Yields of aromatics were found to increase with increasing solvent/feed (extract phase) mass ratio(S/F), while distribution coefficients of aromatics were fixed irrespective of S/F used. Operating temperature did not affect distribution coefficients and yields of aromatics. Distibution coefficients and yields of naphthalene group(carbon numer : 10~12) increased with increasing cabon number. Mass transfer rates of aromatics were also measured with a batch stirred vessel.

  • The mortality was tested to organic control materials to the E. maslovskii adults by the dipping method in laboratory. As the result, in 2014, the extracts of Neem I was not shown control effect by 10.2% control efficacy to E. maslovskii adults in laboratory. The extract of Sophora flavescens roots was shown 84.7% mortality. And other 5 materials were shown 100% insecticidal activity to the adults in laboratory. I n 2015, Plant extract+pyrolignous acid Matrine 0.45% and Plant extract Matrine 0.5+paraffin oil 8% were shown 100% and 94.6% control efficacy, respectively. In the Japanese apricot orchards, the fruit damage rate was low on spray at 21th April in Daap, Gwangyang city, and 8th May Hwangjeon, Suncheon city in Jeonnam province in 2014. The fruit damage rate differed from spray timing and materials, but it was considered that the control of E. maslovskii should be in late April to early May. Otherwise, in 2015, the fruit damage was significantly low in late April spray in Daap, but no significant was in between one spray at 21th, 27th April and 2 spray that days. Meanwhile, the control effect was better 2 times spray of the days in Hwangjeon, Suncheon city in Jeonnam province. Therefore, in organic Japanese apricot, the use of insecticidal materials recommended to control over twice spay in from meddle to late April.

  • To investigate the production of monoterpenoids by Mentha pipperita cells in suspension culture, effects of media formulation, plant growth hormones, initial pH of the media, and cold stress on the production of essential oil and menthol were analyzed. Among the media employed, Lin-Staba medium resulted in the best essential oil production. Addition of 100 mg/l of yeast extract to the Lin-Staba medium induced the cells to produce large amount of essential oil and high content of menthol (0.39 g/l and 19.6%, respectively). In the effect of plant growth hormone, auxine were more effective than cytokinins. At initial pH of 4.7, oil production was good but menthol content was low. However at pH 5.7 the trend was reversed. When the culture temperature was lowered from $27^{\circ}$ to $10^{\circ}$ during 6 hour-dark period, growth was not changed much but essential oil production and menthol content was increased and reached to 528 mg/l and 21%, respectively.

  • Annona muricata L (Annonaceae), commonly known as soursop has a long, rich history in herbal medicine with a lengthy recorded indigenous use. It had also been found to be a promising new anti-tumor agent in numerous in vitro studies. The present investigation concerns chemopreventive effects in a two-stage model of skin papillomagenesis. Chemopreventive effects of an ethanolic extract of A. muricata leaves (AMLE) was evaluated in 6-7 week old ICR mice given a single topical application of 7,12-dimethylbenza(${\alpha}$)anthracene (DMBA 100ug/100ul acetone) and promotion by repeated application of croton oil (1% in acetone/twice a week) for 10 weeks. Morphological tumor incidence, burden and volume were measured, with histological evaluation of skin tissue. Topical application of AMLE at 30, 100 and 300mg/kg significantly reduced DMBA/croton oil induced mice skin papillomagenesis in (i) peri-initiation protocol (AMLE from 7 days prior to 7 days after DMBA), (ii) promotion protocol (AMLE 30 minutes after croton oil), or (iii) both peri-initiation and promotion protocol (AMLE 7 days prior to 7 day after DMBA and AMLE 30 minutes after croton oil throughout the experimental period), in a dose dependent manner (p<0.05) as compared to carcinogen-treated control. Furthermore, the average latent period was significantly increased in theAMLE-treated group. Interestingly, At 100 and 300 mg/kg, AMLE completely inhibited the tumor development in all stages. Histopathological study revealed that tumor growth from the AMLE-treated groups showed only slight hyperplasia and absence of keratin pearls and rete ridges. The results, thus suggest that the A.muricata leaves extract was able to suppress tumor initiation as well as tumor promotion even at lower dosage.

  • The preventive effect of Sosiho-Tang extract administered concurrently with methionine on hepatotoxicity induced by carbon tetrachoride (20% $CCl_4$ in olive oil, 5 ml/kg) in rats was studied. S-GOT values were decreased significantly by the concurrent administration of Sosiho-Tang extract 100 mg/kg with methionine 100 mg/kg and also Sosiho-Tang 200 mg/kg with methionine 100 mg/kg. S-GPT values were decreased remarkably by the concurrent administration of Sosiho-Tang extract 200 mg/kg with methionine 100 mg/kg. In histological observations, the pattern of the contrast group indicated the marked necrosis of the parenchymatous cells around the centrilobular area and the fatty changes of the hepatic cells around the midzonal area, but the concurrent administration of Sosiho-Tang extract 200 mg/kg and methionine 100 mg/kg revealed better improvements than their respective single administration in all pathological aspects.

  • Yukwa is a popular Korean traditional fried rice snack. The high fat content and porous structure of Yukwa cause it to rapidly become rancid, presenting difficult challenges for commercial distribution. In this study, an-tioxidant activities of green tea extracts (GTE) were evaluated in Yukwa fried in soybean oil (SBO), rice bran oil (RBO) and winterized rice bran oil (WRBO) during storage at 4$0^{\circ}C$ for 12 weeks. Lipid oxidation of Yukwa was determined by acid value (AV), peroxide value (POV), p-anisidine value(AnV), totox value and sensory evaluation. The addition of GTE to the oils reduced the increases in AV, POV, AnV, and totox. Totox increased most vapidly in Yukwa fried in SBO, fellowed by RBO>WRBO>SBO+200 ppm GTE>RBO+200 ppm GTE > WRBO + 200 ppm GTE (p<0.05). Sensory evaluation revealed that the addition of 200 ppm GTE delays rancidity in Yukwa by 7~8 weeks; providing compelling evidence that GTE is an effective antioxidant for Yukwa.

  • In the present study, the volatile oil, chloroform extract and methanol extract of the woods of the plants Cedrus deodara and Pinus roxburghii were screened for their antibacterial and antifungal activities against Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Bacillus subtilis, Streptococcus pyogenes, Candida albicans, Aspergillus niger, and Aspergillus clavatus using the Agar diffusion method. The susceptibilities of the microorganisms to the extracts were compared with each other and with a selected standard antibiotic. It was observed that the volatile oil and chloroform extracts showed the significant antibacterial activities while the least antibacterial activity was recorded with the methanolic extracts. The higher Minimum Inhibitory Concentration value of the extracts and oils against fungus suggested that the plants may possess less antifungal activity. Phytochemical analysis and thin-layer chromatography profiling revealed the presence of flavonoids and terpenoids in the oil and chloroform extracts, which could explain the antimicrobial activity. The findings suggest that the Cedrus deodara and Pinus roxburghii have antimicrobial properties and they can be used in the treatment of infectious diseases. However, further work is required in order to isolate the active constituents of the plants responsible for the antibacterial activity.
