A bioequivalence study of $Nimegen^{TM}$ soft capsule (Medica Korea Pharma. Co., Ltd.) to $RoAccutane^{(R)}$ soft capsule (Roche Korea Ind. Co., Ltd.) was conducted according to the guidelines of Korea Food and Drug Administration (KFDA). Thirty healthy male Korean volunteers received each medicine at the isotretinoin dose of 60 mg in a $2{\times}2$ crossover study. There was one week wash-out period between the doses. Plasma concentrations of isotretinoin were monitored by a high performance liquid chromatography (HPLC) for over a period of 48 hours after drug administration. $AUC_t$ (the area under the plasma concentration-time curve from time zero to 48 hr) was calculated by the linear trapezoidal rule method. $C_{MAX}$ (maximum plasma drug concentration) and $T_{MAX}$ (time to reach $C_{MAX}$) were compiled from the plasma concentration-time data. Analysis of variance was carried out using logarithmically transformed $AUC_t\;and\;C_{MAX}$. No significant sequence effect was found for all of the bioavailability parameters indicating that the crossover design was properly performed. The 90% confidence intervals of the $AUC_t$ ratio and the $C_{MAX}$ ratio for $Nimegen^{TM}/RoAccutane^{(R)}$ were $log0.860{\sim}log0.98\;and\;log0.85{\sim}log1.00$, respectively. These values were within the acceptable bioequivalence intervals of $log0.80{\sim}log1.25$. Thus, our study demonstrated the bioequivalence of $Nimegen^{TM}\;and\;RoAccutane^{(R)}$ with respect to the rate and extent of absorption.

Purpose: The clinical utility of brain computed tomography (CT) in detecting temporal bone fracture is not well established. We performed this study to determine the utility of brain computed tomography (CT) in detecting fractures of the temporal bones in correlation with fracture patterns. We used high resolution computed tomography (HRCT) as the gold standard for diagnosing temporal bone fracture and its pattern. Methods: From January 2007 to December 2009, patients who underwent both brain CT and HRCT within 10 days of head trauma were investigated. Among them, 58 cases of temporal bone fracture confirmed by HRCT were finally included. Fracture patterns (transverse or non-transverse, otic capsule sparing or otic capsule violating) were determined by HRCT. Brain CT findings in correlation with fracture patterns were analyzed. Results: Among 58 confirmed cases of temporal bone fracture by HRCT, 14 cases (24.1%) were not detected by brain CT. Brain CT showed a significantly lower ability to detect temporal bone fracture with transverse component than without transverse component (p=0.020). Moreover, brain CT showed lower ability to detect otic capsule violating pattern than otic capsule sparing pattern (p=0.015). Among the 14 cases of temporal bone fracture that were not detected by brain CT, 4 cases lacked any objective physical findings (facial palsy, hemotympanum, external auditory canal bleeding) suggesting fractures of the temporal bones. Conclusion: Brain CT showed poor ability to detect temporal bone fracture with transverse component and otic capsule violating pattern, which is associated with a poorer clinical outcome than otic capsule sparing pattern. Routine use of HRCT to identify temporal bone fracture is warranted, even in cases without evidence of temporal bone fracture on brain CT scans or any objective physical findings suggestive of temporal bone fracture.

This study was conducted to investigate specific stages and distribution of overwintering nymphs of green rice leafhopper, Nephotettix cincticeps by measuring head capsule width. The nymphal head capsule width of the 1st instar to the 5th instar was 0.381, 0.502, 0.673, 0.979 and 1.128 mm, respectively. lts coefficient variation was 5.3, 4.0, 3.0, 4.5 and 5.3%, respectively. Growth ratio of each instar was not significantly different among 2nd to 4th instars as 1.31 to 1.34, but for the 5th instar it decreased as 1.28. The logarithm of the nymphal head capsule width was regressed as a function of the stage number of insects, resulting in LogY = 1.4627 + 0.1192X ($r^2= 0.9993$). Also fitness to the Dyar's law for the nymphal head capsule width of each instar was 98% or over and the Dyar's constant (K) was 1.316. The occurrence of N. cincticeps was maximum at the end of January with 195 individuals/0.25 $m^2$. The most abundant instar in the overwintering N. cincticeps population was 4th instar accounting for over 90%. Population of the 5th instar began to increase from mid-March, and adults began to occur in early April.

Streptococcus iniae is one of the major bacterial pathogens of cultured olive flounder, Paralichthys olivaceus in Korea. This study was carried out to investigate the interaction between morphological characteristics and immune response such as phagocytosis and serum killing activity. They were differentiated phenotypically into two groups, the viscous colonies and the non-viscous colonies, but the strains in both groups were similar in physiological and biochemical characteristics. Electron microscopic examination of the viscous form revealed thick, electron-dense exopolysaccharide materials surrounding polycationic ferritin-stained cells, while the exopolysaccharide material was absent around the non-viscous form of S. iniae. The viscous type strains were disclosed more virulent than those of non-viscous type for olive flounder. The viscous strains were resistant to normal serum killing activity, while the non-viscous strains were susceptible to bactericidal activity of normal serum from olive flounder. The viscous strains were more resistant to opsonophagocytosis and decreased the chemiluminescence response of head kidney macrophages of olive flounder. All of the tested non-viscous S. iniae strains were efficiently destroyed by the macrophage after phagocytosis. Both the viscous and the non-viscous strains invaded and replicated in cultured fish cell line (CHSE-2l4). This cellular invasion may contribute to the pathogenesis of invasive S. iniae infection.

Triflusal is a new antithrombotic agent which inhibits both platelet cyclooxygenase and c-AMP phosphodiesterase activity. The purpose of the present study was to evaluate the bioequivalence of two triflusal capsules, $Disgren^{TM}$ (Myung-In Pharmaceutical Co., Ltd.) and $Tigriri^{TM}$ (Hana Pharmaceutical Co., Ltd.) according to the guidelines of Korea Food and Drug Administration (KFDA). Eighteen normal male volunteers, $22.94{\pm}1.83$ in age and $63.7l{\pm}10.43$ kg in body weight, were divided into two groups and a randomized $2{\times}2$ cross-over study was employed. After one capsule containing 300 mg of triflusal was orally administered, blood was taken at predetermined time intervals and the concentrations of triflusal in serum were determined using HPLC method with UV detector. Pharmacokinetic parameters such as $AUC_t$ $C_{max}$ and $T_{max}$ were calculated and ANOVA test was utilized for the statistical analysis of the parameters. The results showed that the differences in $AUC_t$ $C_{max}$ and $T_{max}$ between two capsules were -0.30%, 0.81 % and -3.03%, respectively when calculated against the $Disgren_{TM}$ capsule. The powers $(1-{\beta})$ for $AUC_t$ $C_{max}$ and $T_{max}$ were 98.29%,84.73% and 81.02%, respectively. Minimum detectable differences $({\Delta})$ at ${\alpha}=0.1$ and $1-{\beta}=0.8$ were all less than 20% (e.g., 12.91%, 18.46% and 19.65% for $AUC_t$ $C_{max}$ and $T_{max}$ respectively). The 90% confid,ence intervals were all within ${\pm}20%$(e.g., $-8.97{\sim}8.37$, $-11.58{\sim}13.22$ and $-16.23{\sim}10.17$ for $AUC_t$ $C_{max}$ and $T_{max}$, respectively). All of the above parameters ($1-{\beta}, {\Delta}$ and 90% confidence intervals) met the criteria of KFDA for bioequivalence, indicating that $Tigriri^{TM}$ capsule is bioequivalent to $Disgren^{TM}$ capsule.

This study was conducted to provide basic information to breeders and agronomists working with sesame. Grain filling rate were investigated for eight plant types classified by branching habit, capsules per axil, carpels and loculi of a capsule. Two typical cultivars were chosen for plant type among 527 gene pools. Grain filling rate didn't increase with little difference between lower and middle part capsules, Jut significantly decreased in upper part. Grain filling rate of lower part, main stem and center capsules appeared higher than that of upper part, branch and side capsule for grain filling. Mono-capsule setting and unbranched plant type were higher for grain filling than tricapsule setting and branched type due to inactive ripenness on branched capsule. NMB type showed that best maturity and relatively good grain filling in BTB type despite it's largest sink capacity. NTQ and BTQ type appeared poor ripenness because of immaturity of higher part side capsules; however it was believed that there were still possibilities for improving ripenness in 3 capsule and 4 carpels 8 loculi type by the good maturity of 1 capsule and 4 carpels 8 loculi type.

Andy Warhol's "Time Capsule" is an individual's daily record, but it can also be evaluated as an artwork. Andy Warhol kept most of his items in boxes until his death in 1974. Warhol's personal records contained receipts, invitations, memos, letters, voice tapes, newspapers, magazines, fan letters, mails, and exhibit materials. Andy Warhol's act of collecting items was continuous and repetitive, giving others a deeper insight into the artist's life. Warhol constantly recorded daily repetitive behaviors such as the people he met, a list of books he bought, and movies he had watched as a record producer. In addition, occasionally, he was in the position of an archivist, collecting and organizing others' records. As such, he expressed his passion for recording his surroundings. His intentionally produced or collected records contain valuable information, not only of himself but also of the people surrounding him. His personal records show that it is the material that enables people to understand and appreciate his relationship with contemporary artists, as well as the artist's education and the conditions during his time.

Objectives : Gambigyeongsinhwan 16 (GGEx16), gambigyeongsinhwan 18 (GGEx18) and gambitongseong capsule are shown to be involved in the regulation of obesity. Therefore, the aim of this study was to compare the reporter activity of anti-obesity genes such as peroxisome proliferator-activated receptor ${\alpha}$ ($PPAR{\alpha}$) and $PPAR{\delta}$ by GGEx16, GGEx18 and gambitongseong capsule. Methods : After NMu2Li liver cells, C2C12 skeletal muscle cells and 3T3-L1 preadipocytes were treated with GGEx16 (1 ${\mu}g/ml$), GGEx18 (1 ${\mu}g/ml$) and different concentrations of gambitongseong capsule, the transactivation of $PPAR{\alpha}$ and $PPAR{\delta}$ was measured by a luciferase reporter gene assay. Results : $PPAR{\alpha}$ reporter gene activity in NMu2Li liver cells and 3T3-L1 preadipocytes was significantly increased by GGEx16, GGEx18 and gambitongseong capsule compared with control, whereas $PPAR{\alpha}$ reporter gene activity in C2C12 skeletal muscle cells was significantly increased by GGEx18 only compared with control. Similarly, $PPAR{\delta}$ reporter gene activity in 3T3-L1 preadipocytes was also significantly increased by GGEx18 compared with control. $PPAR{\delta}$ reporter gene activity in C2C12 skeletal muscle cells was significantly increased by GGEx16 and GGEx18 compared with control although $PPAR{\delta}$ reporter gene activity in NMu2Li liver cells was not changed by these three formulas. Conclusions : These results suggest that all three formulas have the ability to stimulate $PPAR{\alpha}$ and $PPAR{\delta}$ transactivation in animal cell lines with high metabolic rates. In particular, this effects were most prominent in GGEx18-treated cells. In addition, it is likely that GGEx18 may be used as an effective anti-obesity composition.
