Physical activity and exercise can promote sensorimotor recovery from central nerve injury. It has been suggested that the functional recovery promoted by exercise training after spinal cord injury might be associated with insulin-like growth factor-I in the inflicted muscle. To investigate morphological and biochemical change of the soleus muscle after spinal cord injury, all tissues were used for H&E, immunofluorescence staining and Western blot. Also, BBB-test was used to evaluate behavioral improvement after spinal cord contusion. Thirty male Sprague-Dawley rats ($230{\pm}10\;g$; 7week in age) were assigned equally to three different groups; Normal (n=10), SCI (n=10), SCI+TMT (n=10). Every rat in SCI and SCI+TMT groups underwent laminectomy at T9 level and then contusion on the exposed spinal cord site in anesthetized condition. After one week-recovery from contusion, every rat in the SCI+TMT group exercised on a motorized treadmill for 30min/d, 5d/wk for 7wks. TMT followed by injury increased IGF-I induction levels in the soleus muscle and inhibited muscle atrophy. Behavioral scales for 4 and 8 weeks after spinal cord injury were improved in the SCI+TMT group compared to the SCI group. These results suggest that treadmill exercise after spinal cord injury might promote functional recovery along with muscle regrowth through the up-regulation of IGF-1 in muscle tissue.

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 investigated the variability of WTP estimates(i.e. mean or median) with ad hoc assumptions of specific parametric probability distributions(i.e. normal, logistic, lognormal, and exponential distribution) to estimate WTP function using dichotomous choice CV data on mortality risk reduction. From the perspective of policy decision, the variability of these WTP estimates are intolerable in comparison with those of Turnbull nonparametric estimation method which is free from ad hoc distribution assumptions. The Turnbull nonparametric estimation can avoid a kind of misspecification bias due to ad hoc assumption of specific parametric distributions. Furthermore, the WTP estimates by Turnbull nonparametric estimation are robust because the similar estimates are elicited from a dichotomous choice or double dichotomous choice CV data, and the statistically significant WTP estimates can be obtained even though it is not possible by parametric estimation methods. If there are considerable variability among those WTP estimates by parametric estimation methods in condition with no criteria of model adequacy, the mean WTPs from Turnbull nonparametric estimation can be the robust estimates without ad hoc assumptions, which can avoid controversial issues in the perspective of policy decisions.

The cosmetic and stimulating effects of lemon oil have been widely proven in the fields of beauty therapy and psychology therapy. But the lemon oil's proper effects on the anti asthma and the anti inflammation have not rarely been verified. This study was conducted to find out the lemon oil's effects on the anti asthma and anti inflammation in the OVA-induced allergic asthma mice model. OVA-induced allergic asthma mice were divided into 4 groups consisting of normal group, control group, positive control group and experimental group. 0.3% of lemon oil was nebulized to experimental group for 3 weeks on a basis of 3 times per week and 30 min each time. After 6 weeks from the initial experiment, the degree of hyper activeness of respiratory system, the hematological change, the amount of the cytokein in serum, the change of airway organization were evaluated. The results showed that lemon oil controled effectively the hyper activeness of respiratory system and restricted the multiplication of cells in acidophil in terms of statistical significance. It also turned out that lemon oil restricted effectively the infection of airway reaction and the hyper sensitiveness of respiratory system by controlling the creation of histamine(cytokein) and IgE.

The c-myc proto-oncogene is Involved In the control of normal cell proliferation and differentiation of many cell lineages. Although it has heen suggested that c-myc may play an important role in the mammalian early development, it Is unclear whether the embryonic c-myc mRNA is originated from zygotic gene expression or stored maternal message. Thus, we have construded expression vectors, In which the 5, flanking sequences including c-myc promoter region and a large non-coding exon I are fused 'sith E. coli lacZ gene that encedes $\beta$-galactosldase as a reporter. As c-myc exon I contains a modulatory sequence, we designed t, vo types of vectors (pcmyc.Gall and pcmyc-Ga12) to examine the role of exon I in c-myc expression. The former contains the complete exon I and the later has a deletion in 40 bp of modulator sequence located In the exon I of c-myc These vectors were microInjected into fertilized one-cell embryos and $\beta$-galactosidase activity was examined by X-gal staining during early embryogenesis. $\beta$-galactosidase activity derived from c-myc promoter was decreased at two-cell stage. The expression level directed by pcmyc- Ga12 was similar to that of pcmyc-Gal1, indicating that the medulatory sequence in exon I may not be Involved at least In the regulation of embryonic c-myc expression. In summary, the present study indicates that the c-myc promoter is functional at the early stage embryo, and the regulation of c-myc expression is under the control of "zygotic" clock of preimplantation mouse embryos.e embryos.

This study was attempted for clinical investigation regarding with Apgar score changing phase of newborns and their sucking power related the score and weight. The data for this study obtained from 545 newborns who were born at Dept. of obstetric WooSok Hospital, Korea University from Jan. to Sept.. 1373. It is hoped that this study will contribute to nursing care planning of newborns in nursery. The Apgar score was checked in the delivery room at 1 minute after delivery by Doctor and rechecked at 30 minutes and 1 hour after delivery by nurses. The results obtained were as follows: 1. The total newborn numbers at 1 minute after delivery were 545, at 30 minutes were 542 (3 dead) and at 1 hour were 540. The babies were divided into 3 groups by the Apgar score. The frequency of group 1 (score 1 to 4) at each times were 5.0%, 0.9%, 0.4%, group 2 (score 5 to 7) 11.2%, 4.1%, 1.7% and group 3 (score 8 to 10) 83.8%, 95.0%, 97.9%. 2. The group I was found most frequently among the cases of less than 2, 500g and group 3 was found among the cases over 2.500g. It was found that there was a tendency of delaying in recovery process of low score among the premature and low birth weight newborns. 3. The type of delivery, breech and other I e was found worst and C-Section was the second, however normal spontaneous delivery was found the best. 4. In observation of sucking power of the newborn related its score and weight, good, fair, poor marks were given. But for convenience of statistical analysis. good and fair was collected together and poor alone evaluated. The result of group 1.2 examined statistically by F.E.T shown no relation between newborn weight and sucking power. however group 3, examined by X$^2$test shown very significant relation between newborn weight and sucking power. 5. The mortality rate of newborn while they were in hospital was found 2.6% to 545 of birth and all cases of dead belonged to group 1 at 1 minutes after delivery. 64.3% of the dead was found among the cases less than 2, 500g. 6. It was found that in this observation premature and Newborn asphyxia had influence to low score at birth. Conclusively, good anthemata carr should be emphasized in order to prevent main causes of these and should avoid abnormal delivery as possible.
