Echinococcus granulosus is an important zoonotic parasite globally causing cystic echinococcosis (CE) in humans and animals. In this study, prevalence of CE and variation of cox1 gene sequence were analyzed with isolates E. granulosus collected from different areas in northern Xinjiang, China. The survey showed that 3.5% of sheep and 4.1% of cattle were infected with CE. Fragment of cox1 was amplified from all the positive sheep and cattle samples by PCR. In addition, 26 positive samples across the 4 areas were included. The isolates were all E. granulosus sensu stricto (s.s.) containing 15 haplotypes (Hap1-15), and clustered into 2 genotypes, G1 (90.1%, 91/101) and G3 (9.9%, 10/101). Hap1 was the most common haplotype (48.5%, 49/101). Hap9 were found in humans samples, indicating that sheep and cattle reservoir human CE. It is indicate that E. granulosus may impact on control of CE in livestock and humans in the region.

We investigated Euphausia pacifica population in Korean waters in 2016 By samplings for genetic structur at five stations. Three sampling stations were located in the middle of the water masses which were clustered by temperature and salinity whereas the other stations were at the boundaries of the water masses. We amplified a 566 bp region and compared it with sequences of E. pacifica distributed in other waters. Sequences were classified two clades, and a clade was formed in the station E. Genetic distance of station E was close to E. pacifica present in Bering Sea, while it was distant to E. pacifica present in Yellow Sea near China. In genetic analysis, seven haplotypes were formed. Hap-1 and Hap-2 were shared in all five stations, while Hap-3 was shared in station W and WS. Four independent haplotypes were present in station E. Haplotype and nucleotide diversity were the highest in station E and the lowest in station S. The F_ST distances between station E and other stations were the highest, but distances among other stations were low. As a result, we concluded that E. pacifica, which is distributed in Korean waters, has a genetic population differentiation in the East Sea (station E).

This study is on the changing pattern of fish-and-shellfish uses during the last two thirds of Chosun period on the premise that they are influenced by development of fishing technology. With a literary approach, this paper researches how fish-and-shellfish production and consumption pattern changed, especially in relation to technological development of fisheries. First, we examine into the changes of fishery production. And next, we analyze the kind and cooking method of fish-and-shellfish in [Eum-sik-di-mi-bang](1670) and [Gyu-hap-chong-seo](1815). The analysis of two books revealed that there were significant differences in fish-and-shellfish uses. Because the two books were written with a gap of 145 years and the development of fishing technology and remarkable changes of fishery production affected on the fish-and-shellfish uses. Due to primitive fishing tools and skills, fresh-water and reverse-river-fish and shellfish had been caught in substantial amount until the middle ages of Chosun period. As a result, the availability of seafood were limited extremely even in the upper classes. These situations are evidenced by the analysis of [Eum-sik-di-mi-bang]. Only 12 kinds of fish-and-shellfish are described in [Eum-sik-di-mi-bang]. Most of the sesfoods is mollusc which is easy to catch. As for the salt-water fish, dried cod and dried herring were mentioned. Mullet, the reverse-water-fish, is used most frequently. Only one kind of 'Hoe', which needs extreme freshness, is described. This means that the use of fresh fish-and-shellfish was very limited to some kinds which could be caught near the village. As the netting fishery began to be developed in the 18th century, the production of some salt-water fishes, such as anchovy, shrimp, yellow corvina, pollack, and herring, had increased remarkably to make marine resources more available. Small fish, such as anchovy and shrimp were preserved as 'Jeot-gal' and sold nationwide. Therefore, 'Jeot-gal' and seafood could be used in Kimchi around this time and had a deep influence on the change of Kimchi in taste and nutrition. In [Gyu-hap-chong-seo], 33 kinds of fish-and-shellfish are described. Including cod and herring, 17 kinds of sea water fish and mollusc are mentioned. Some of these are consumed in fresh state, neither as dried nor as salted. Because the merchants promoted the transport of seafoods to other regions according to the growth of commercial economy. As a result the diet of the people could be enriched by the various seafoods.

Objective: The aim of this study was to evaluate the remineralization of interdentally stripped teeth after fluoride gel or hydroxyapatite paste application. Methods: After interdental stripping, 1.23% fluoride gel or 10% hydroxyapatite paste was applied three times a day, with a duration of four minutes, for a week. Scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS) were used to compare the change of surface contents and crystal structures before and after the application of fluoride gel or hydroxyapatite paste. Results: EDS analysis indicated that calcium contents were increased after 10% HAp paste application on stripped enamel (p < 0.01). SEM view showed that enamel surfaces in groups of 1.23% APF gel or 10% HAp paste application were smoother than those of control group, which was regarded as filling of the pore structure. And pores between crystal structures in groups treated with 1.23%, APF gel or 10% HAp paste were smaller than those of control group. Conclusions: Application of APF or HAp on stripped enamel could positively influence on the surface contents or crystal structure.

The several Chinese herbs such as Soon-Ki-Hwal-Hyul-Tang, Bo-Yang-Hwan-O-Tang, Seong-Hyang-Jeong-Ki-San, So-Hap-Hyang-Won and O-Yak-Soon-Ki-San were extracted with water and then lyophilized. For identification of the effect of extracted herbs, they were medicated to 103 patients of cerebrovascular accident for 4 week. They were hospitalized in D-Oriental Medical Hospital from April to August in 1999. The herbs were extracted with water and lyophilized and then, used as samples. The medical history of each patient was detected and analyzed from their medical records. The results were as follows; 1) Each sample (Soon-Ki-Hwal-Hyul-Tang, Bo-Yang-Hwan-O-Tang, Seong-Hyang-Jeong-Ki-San, and O-Yak-Soon-Ki-San) was statistically significant differences of systolic blood pressure(t=4.22, P=0.0004; t=3.44, P=0.0028; t=2.11, P=0.0463; t=3.23, P=0.0052). The statistically significant difference of diastolic blood pressure showed by medicated with Soon-Ki-Hwal-Hyal-Tang, Seong-Hyang-Jeong-Ki-San, and O-Yak-Soon-ki-San (t=2.13, P=0.0459; t=2.68, P=0.0136; t=3.12, P=0.0066). 2) The statistically significant difference of the arm/leg-ROM showed by medicated with Soon-Ki-Hwal-Hyul-Tang, Bo-Yang-Hwan-O Tang, So-Hap-Hyang-Won(t=4.74/4.95, P=0.0002/0.0001; t=2.25/2.44, P=0.0368/0.0248; t=5.85/6.76, P=0.0001/0.0001). 3) In the verbal disorder, Soon-Ki-Hwal-Hyul-Tang, Bo-Yang-Hwan-O-Tang had statistically significant differences(t=4.50, P=0.0002; t=3.32, P=0.0036). 4) In the conscious disorder, Soon-Ki-Hwal-Hyul-Tang, Bo-Yang-Hwan-O-Tang, Seong-Hyang-Jeong-Ki-San, and So-Hap-Hyang-Won had statistically significant differences(t=6.32, P =0.0001; t=8.32, P=0.0001; t=3.74, P=0.0012; t=5.14, P=0.0001). 5) Bovine aortic endothelial cell (BAEC) were cultured in DMEM treating 0.01mg/ml, and 0.1mg/ml of each lyophilized samples for 24 hours. In BAECs were treated by 5 kinds of samples, the effect of So-Hyap-Hyang-Won induced syncytium of adjacent endothelial cells. It may induce the recovering of the damaged blood vessels in cerebrovascular accidental patient by angiogensis of endothelial cells. Therefore, it suggests that the medication of So-Hap-Hyang-Won will help to nursing care for cerebrovascular accidental patients.

The study aimed to compare the whitening efficacy of a strip and gel containing 2.9% hydrogen peroxide, using a tooth whitening light activator. The whitening effect was compared through in vitro and in vivo studies. In the in vitro study, we used stained hydroxyapatite (HAP) specimens as artificial teeth. HAP specimens were made using HAP powder and polyvinyl alcohol solution, and stained by modified Stookey's method. A whitening gel and whitening strip were applied to the respective specimens for 20 minutes, with a light activator. The color changes were measured using a colorimeter. In the in vivo study, one group (test 1) used the gel with a light activator and the other group (test 2) used a strip with the same activator for 15 minutes a day, for four consecutive days. An organoleptic evaluation using a Vita shade guide and instrumental evaluation using a Shade eye-NCC (Shofu Co., Japan) were performed. The color change values (${\Delta}E^*$) in the in vitro study revealed the strip with the light activator to be more effective than the gel with the same activator (p<0.001). In the in vivo study, even though there was no significant difference between the groups with respect to the ${\Delta}E^*$, using either the Shade eye-NCC or the Vita shade guide, the change in yellowness (${\Delta}b^*$) was statistically significant (p=0.024). In conclusion, test 2 group that used 2.9% hydrogen peroxide strip with a light activator, showed a tendency towards increased whitening than test 1 group that used the gel with the same activator; however further studies are needed to validate the above finding.

This study was performed from March to September 1997 on 95 healthy students to observe the effects of acupuncture at Hap-kok (LI4) according to the meridian and qi-xue(氣血) phenomenon of oriental medicine's theory. Skin temperature on the Hap-kok (LI4) and Chun-Choo (ST25) were measured by D. 1. T. I. (Digital Infrared Thermograph Imaging) before acupuncture stimulation and 1min, 10 min after acupuncture stimulation. 1. In healthy students, the left and right mean temperature of LI4 and ST25 was $29.04\;^{\circ}C,\;29.12\;^{\cir}C\;and\;30.29\;^{\circ}C,\;30.22\;^{\circ}C$ respectively. 2. In control group, the time dependent changes for 10 min of LI4 and ST25 were $-0.32\;^{\circ}C,\;-0.36\;^{\circ}C\;and\;-0.5\;^{\circ}C,\;-0.46\;^{\circ}C$ respectively, however, the thermal differences of both sides LI4 and ST25 were not changed for 10 min. 3. In acupuncture stimulation of both sides LI4, the time dependent changes of ST25 were $-0.13\;^{\circ}C,\;-0.06\;^{\circ}C$, and the thermal differences of both sides ST25 were reduced, but not changed significantly. In acupuncture stimulation of right side LI4, the time dependent changes of LI4 were $-0.1\;^{\circ}C,\;-0.32\;^{\circ}C$ respectively, and the thermal differences of both sides LI4 were increased more than control, but not significantly. Also, that of ST25 were changed by $-0.69\;^{\circ}C,\;-0.63\;^{\circ}C$ respectively, but not significantly. 4. In acupuncture stimulation group, it was classified following the thermal differences of both sides LI4 and ST25, and the effects of acupuncture were observed by changes of classification. The acupuncture of both sides LI4 results in temperature of the left side ST25 to be high after acupuncture. The acupuncture of right side LI4 results in increased ratio of the left side higher than right LI4. The above results indicates that D. I. T. I. was a useful method to observe follow-up the effects and changes by acupuncture stimulation on objective evaluation of phenomenon for the meridian system. Thus, acupuncture on LI4 affects to thermal changes of ST25 and LI4, but exact examination of thermal changes on ST25 will have to be.

Magnesium-substituted BCP (biphasic calcium phosphate) powders were prepared by incorporating small amounts of magnesium into the structure of different hydroxyapatite (HAp)/${\beta}$-tricalcium phosphate (${\beta}$-TCP) ratios through coprecipitation method. A series of magnesium substitutions ranging from 0, 0.5, and 1.0 wt%, which are comparable to the measured magnesium contents, were performed. The obtained powders were characterized by the following analytical techniques: X-ray diffraction analysis (XRD), Thermo Gravimetric Analyzer (TGA) and Fourier transform infrared spectroscopy (FT-IR). The results have shown that substitution of magnesium in the calcium-deficient apatites resulted in the formation of biphasic mixtures of different HAP/${\beta}$-TCP ratios after heating above $1000^{\circ}C$. The 1.0 wt% magnesiumsubstituted-BCP were soaked in Hank's solutions after 2 weeks to observe the morphology of the biocement, especially needle-like hydroxyapatite crystals and to estimate the length and diameter of nanoneedle crystals.
