Purpose: This study was attempted to estimate the effects of diabetic education fortified with individual practice on plasma glucose, self-care, and self reported physical symptoms in type 2 diabetes patients Method: The subjects consisted of 46 patients with type 2 diabetes patients, who took the hospitalization diabetes education program from July 2003 until February 2004 at Seoul C university hospital. The experimental group was assessed at preand post intervention. The diabetes education was provided for one week. The education consisted of diabetes education videos for the diabetic introduction, group education for medication therapy, dietetic treatment and diabetes complication education. Also individual education for nurses examination of glycemia and insulin injection practice. Results: The HbA1c values significantly decreased from 9.6% on the time of hospitalization to 7.4% 3 months after discharge. In respect to the number of days of self-care, medication, diet, exercise, cleansing feet, and carrying sweets to prepare for hypoglycemia all significantly increased 3 months after discharge compared to the values at the time of hospitalization. Self reported physical symptoms were also significantly increased 3 months after discharge compared to the time of hospitalization. Conclusion: The diabetic education fortified with individual practice can be practically used as a plan for managing glycemia, self-care, and self reported physical symptom of diabetes patients.

In Paralichthys olivaceus and Nibea japonica, response to live air (5hr) or ship (25hr) transportation was assessed, by determining the levels of plasma cortisol, glucose, lactic acid and osmolality, as well as hematological parameters namely hematocrit (Ht), red blood cell (RBC) count, hemoglobin (Hb), corpuscular volume (MCV), corpuscular hemoglobin (MCH) and corpuscular hemoglobin concentration (MCHC). In the experimental series I, the olive flounder was subjected to stress or no stress for 1hr, prior to its air transportation for 5hr. The stress suffered by the flounder prior to air transportation resulted in significant reduction in Ht, but increases in MCH and MCHC. Air transportation led to increases in MCV and MCH in both the stressed and non stressed groups. In the non stressed group it led to significant increase in Ht but decrease in MCHC. In the stressed group, the air transportation led to significant increases in osmolality and plasma cortisol from 5 to 38.5ng/$m\ell$. Non stressed groups did not show significant differences in this before and after transportation. In the experiment II, the red blood cell (RBC) count ranged from 2.5$\times$10$^{6}$ /${mu}ell$ to 2.7$\times$10$^{6}$ /${mu}ell$ in the flounder and 1.9$\times$10$^{6}$ /${mu}ell$ to 2.1$\times$10$^{6}$ /${mu}ell$ in the croaker during the pre- and post-transportation, respectively. In the croaker the shipping led to significant increase in plasma cortisol from 26 to 35ng/$m\ell$ but decrease in glucose from 91.0 to 26.4mg/㎗. For glucose the reverse (39.0 to 51.0mg/㎗) was true for the flounder.

The present study was aimed to study the effect of aqueous extract of Tinospora cordifolia and autologous plasma on uterine infections. Buffaloes in estrus, 40 days and above postpartum were checked for uterine infections. Animals having uterine infections were randomly divided into three groups of six animals each. Buffaloes in group I, II and III (control) were given intrauterine infusion of aqueous extract of Tinospora cordifolia (3,000 mg total dose), autologous plasma (150 ml) and phosphate buffer saline (150 ml) respectively, in three divided doses, once daily for three consecutive days, starting from the day of estrus. A fourth group (IV) comprising of six buffaloes having no uterine infection was also included in the present study. Buffaloes were inseminated artificially on next estrus following treatment and confirmed for pregnancy 60 days later. Bacterial population in CVM of buffaloes in group I, II and III was significantly (p<0.05) higher than group IV. After treatment there was a significant (p<0.01) reduction in bacterial population in group I (83.496$\pm$7.755%) and group II 80.233$\pm$5.799%) than group in III 7.557$\pm$33.551%) at next estrus. There was non-significant improvement in first service conception rate (CR, 33.33%) and overall conception rate (OCR, 27.27%) in group I, in comparison to group III (first service CR-16.67%; OCR-20.0%). No significant improvement was seen in OCR (22.22%) in-group II also in comparison to group III. The improvement in group I was however, nonsignificantly lower than normal animals of group IV (First service CR-16.67%; OCR-36.33%).

For advanced TFT-LCD manufacturing processes, dry etching of thin-film layers(a-Si, $SiN_x$, SID & gate electrodes, ITO etc.) is increasingly preferred instead of conventional wet etching processes. To dry etch Al gate electrode which is advantageous for reducing propagation delay time of scan signals, high etch rate, slope angle control, and etch uniformity are required. For the Al gate electrode, some metals such as Ti and Nd are added in Al to prevent hillocks during post-annealing processes in addition to gaining low-resistivity($<10u{\Omega}{\cdot}cm$), high performance to heat tolerance and corrosion tolerance of Al thin films. In the case of AI-Nd alloy films, however, low etch rate and poor selectivity over photoresist are remained as a problem. In this study, to enhance the etch rates together with etch uniformity of AI-Nd alloys, magnetized inductively coupled plasma(MICP) have been used instead of conventional ICP and the effects of various magnets and processes conditions have been studied. MICP was consisted of fourteen pairs of permanent magnets arranged along the inside of chamber wall and also a Helmholtz type axial electromagnets was located outside the chamber. Gas combinations of $Cl_2,{\;}BCl_3$, and HBr were used with pressures between 5mTorr and 30mTorr, rf-bias voltages from -50Vto -200V, and inductive powers from 400W to 800W. In the case of $Cl_2/BCl_3$ plasma chemistry, the etch rate of AI-Nd films and etch selectivity over photoresist increased with $BCl_3$ rich etch chemistries for both with and without the magnets. The highest etch rate of $1,000{\AA}/min$, however, could be obtained with the magnets(both the multi-dipole magnets and the electromagnets). Under an optimized electromagnetic strength, etch uniformity of less than 5% also could be obtained under the above conditions.

Purpose: Sulforaphane is a naturally-occurring isothiocyanate abundant in broccoli. It has been suggested as a promising antioxidant. In this study, the therapeutic effect of sulforaphane in paraquat intoxication was investigated. Methods: Paraquat was administered via the tail vein, after which sulforaphane or a vehicle (4% DMSO) was administered intraperitoneally 15 minutes after paraquat administration. Histological injury, lipid peroxidation, plasma cytokine (IL-6, IL-10), and nitric oxide were measured. In addition, the effect of sulforaphane on survival in paraquat-intoxication was observed. Results: Regarding histological injury, lipid peroxidation, and plasma cytokine and nitric-oxide response, sulforaphane administration showed no protective effects in paraquat-intoxicated rats. Rather, it increased mortality (log rank p=0.03) and caused lipid peroxidation, as well as plasma cytokine and nitric-oxide production, to be increased. Conclusion: Sulforaphane had no therapeutic effect on paraquat-intoxicated rats; rather, it increased mortality.

This study was conducted to investigate the potential embryo-fetal toxicity and toxicokinetics of the antimalarial agent artesunate (ARTS) in Sprague-Dawley rats. Pregnant rats were administered ARTS daily from gestational day 6~15 via oral gavage, at test doses of 0, 2, 4, or 8 mg/kg (22 females per group). The fetuses were examined for external, visceral, and skeletal abnormalities on gestational day 20. With regard to the dams, there were no deaths, treatment-related clinical signs, changes in body weight, or food intake in any of the treatment groups. There were no treatment-related gross findings at necropsy in any treatment group. In the 8 mg/kg group, there was a decrease in gravid uterine weight and in the weight of female fetuses. There was also an increase in fetal deaths (primarily late resorptions) and an increase in post-implantation losses (37%) at 8 mg/kg. An increase in the incidence of visceral and skeletal variations at 4 and 8 mg/kg was observed. These defects included minor changes in the appearance of the kidney and thymus, as well as absent ribs or thoracic vertebrae. Toxicokinetics were assessed in a parallel study, using 4 mated females per group. Using liquid chromatography-mass spectrometry (LC-MS) analysis, the concentration of ARTS and its metabolite dihydroartemisinin (DHA) were quantified in plasma from rats on gestational days 5, 6, 10, and 15. Amniotic fluid was assayed for ARTS and DHA on gestational day 15. There was evidence of rapid conversion of ARTS to the metabolite DHA in maternal plasma, since ARTS could not be consistently detected in plasma at the three doses tested. ARTS and DHA were not detected in amniotic fluid at gestational day 15, indicating limited placental transfer of the two agents. The embryo-fetal no-observable-adverse-effect level (NOAEL) of the test item was considered to be 8 mg/kg/day for dams, and 2 mg/kg/day for embryo-fetal development.

This study correlated changes in estradiol-l7$\beta$ ($E_2$), testosterone (T), 17$\alpha$,20-dihydroxy-4-pregnen-3-one (DHP), and vitellogenin (VTG) levels with changes in the gonadosomatic index (GSI) and ovarian histology during the annual reproductive cycle of the wild marbled sole, Limanda yokohamae. Synchronous oocyte development occurs in this fish. Ovary maturity was classified into four periods, based on histological observations: the spawning (December to February), post-spawning (February to April), recovery (May to August), and vitellogenic (September to November) periods. Seasonal changes in the GSI were inversely correlated with water temperatures and reflected the degree of ovarian maturity. Plasma VTG levels were correlated with changes in the GSI, which increased from September to a peak in January, and levels remained comparatively high until February. Estradiol-17$\beta$ was at baseline levels (<0.11 ng/mL) during the spring and summer, and peaked rapidly (1.55$\pm$0.445 ng/mL) from October to January. Plasma T and DHP levels had a similar profile; they rose markedly during the spawning period and remained low (or were not detectable) from spring through autumn. These data indicate that changes in plsama steroid hormones and VTG levels are correlated with the annual ovarian activity of the marbled sole. Based on these results and published reports, it appears that in this species DHP is the most important maturation-inducing steroid and that T is also related to final maturation.

Quercetin을 50 및 100mg/kg의 용량으로 mouse에 경구투여 후 흡수, 대사 및 조직내 농도를 조사하였으며 일부의 시험은 비교를 위해 rat에서도 수행하였다. Quercetin은 mouse에서 신속히 흡수되어 l시간 후면 최고 혈장내 농도에 도달하였으며 4시간 후에는 현저하게 농도가 감소하였다. 주요 대사체인 isorhamnetin의 혈장내 농도도 신속하게 증가하였으나 quercetin 보다는 높은 농도로 유지되는 시간이 길었다. Rat에서 알려진 현상과 같이 quercetin이나 isorhamnetin 모두 유리상태로 존재하지 않고 대부분 glucuronide/sulfate의 포합체 형태로 존재하였다. Quercetin 및 isorhamnetin의 조직내 농도는 투여 1시간 및 6시간 콩히 간장>신장>비장>혈장의 순이었으며 이 순서는 rat에서도 마찬가지였다. 이 연구결과를 통해 mouse에서 quercetin이 경구투여 후 실제로 흡수되며 사람이나 다른 동물종에서 관찰된 것과 같이 quercetin은 신속하게 전환됨을 관찰하였다. 또한 이 결과는 mouse를 이용한 실험에서 지금까지 규명된 quercetin의 다양한 약리효과를 설명하는 데 필요한 자료의 역할을 할 수 있을 것이다.
