The Artemisia capillaris THUNB is a perennial herb that belongs to the family Compositae spp and probably the most common plant among the various herbal folk remedies being used in the treatment of abdominal pain hepatitis chronic liver disease, jaundice and coughing in Korea. Recently the biological and pharmacological actions of herb have been studied well such as antibacterial, antidiabetic and antitumor activities. This experiment was conducted to investigate antitumor and immunomodulatory effects of Artemisia capillarix extracts against Hepa-1c1c7 and Sarcoma 180 cancer cells on in vivo experimental tests. On in vivo experimental tests using 280 ICR mice the gain of body weight in the control-group mice bearing Sarcoma 180 ascites tumor was 1.5 times more than that of the normal-group mice after 33 days. However, the gain of body weight in all experimental groups administered with Artemisia capillaris extracts was significantly lower than that of the control-group mice (P<0.05). The mean survival times of mice administered with Artemisia capillaris extracts of 25 and 100 mg/kg for 28 days were shown to be 25.39% and 15.39% longer than that of the control-group mice injected with saline (P<0.05). Artemisia capillaris extracts showed the highest tumor inhibition effects, which were 42.4% and 27.2% when intraperitoneally injected with doses of 25 and 100 mg/kg once a day for 28 days in inoculated ICR mice with Sarcoma 180 solid tumor cells (P<0.05). The results suggest that Artemisia capillaris methanol extracts have prominent antitumor effects on the cancer cell lines Hepa-1c1c7 and Sarcoma 180.

Background The stenosis of the coronary artery may decrease myocardial oxygen supply and occur myocardial ischemia or infarction. Soojeomsan, one of analgesics is generally regarded to have the effect of vitalizing blood, expelling blood stasis and alleviation cardiac pain. Methods The purpose of this experimental study is to find the influence of Soojeomsan on cardiac enzyme (CPK, Na-K ATPase) of ischemic and reperfused rat hearts which are isolated under the Langendorff apparatus. Ischemia was induced In isolated hearts of Sprague-Dawley rats by ceasing the perfusion for 20 minutes. The experiments were divided into a normal saline orally administered group(control group), a Soojeomsan orally 20ml administered group(sample A) and a Soojeomsan orally 30ml administered group(sample B). The CPK (creatinine phosphokinase) and Na-K ATPase activity of this three group were measured and compared in order to assess the influence of Soojeomsan on protection of isolated rat hearts from ischemia. Results 1. CPK was significantly reduced in Sample A group and Sample B group in comparison with control group in reperfusion(P<0.01), and there were no significant difference between Sample A and B. 2. Na-K ATPase activity was significantly increased in Sample A group and Sample B group in comparison with control group in ischemia(P<0.001), and the activity was significantly higher in Sample B then in Sample A.(P<0.01) 3. There were no significant difference in Na-K ATPase activity of the three groups after reperfusion. Conclusion Soojeomsan has effects to decrease CPK activity and activate Na pump. This result in protection of the myocardium of isolated rat hearts from ischemia.

Objective : Membranous nephropathy (MN) is one of the most commonest forms of glomerular disease in man and the most frequent cause of the adult idiopathic nephrotic syndrome. Some investigators recommend no treatment, while others propose aggressive therapy, including prednisolone plus an immunosupressant such as chlorambucil or cyclophosphamide. But a more effective way to treat MN is not defined yet. This study was to evaluate the effects of Patriniae Radix extract (PRE) on the MN induced by cBSA in mice. Methods : Mice were divided into 4 groups. The first group (normal) was injected with saline. The second group (control) was treated with cBSA (10 mg/kg i.p) only. The third group, named PRE-2S0, was treated with cBSA (10 mg/kg i.p) and PRE (250 mg/kg, p.o). The fourth group, PRE-500, was treated with cBSA (10mg/kg i.p) and PRE (500mg/kg, p.o). After cBSA and PRE treatment for 4 weeks, we measured change of body weight, 24hrs proteinuria, serum albumin, total cholesterol, triglyceride, BUN, creatinine, IgG, IgA, IgM, $TNF-\alpha$, $IL-1\beta$, and $IFN-\gamma$ levels and the mRNA expression of $IFN-\gamma$, IL-6, and IL-10. The morphologic changes of renal glomeruli were also observed with a light microscope and an electron microscope. Results : The levels of 24 hrs proteinuria and serum triglyceride. BUN. IgG. $TNF-\alpha$, and $IL-1\beta$ significantly decreased in both PRE groups, while the level of serum albumin significantly increased in both PRE groups. The mRNA expression of IL-10 in splenocytes considerably increased in both PRE groups. The mRNA expression of $IFN-\gamma$ and IL-6 in splenocytes considerably increased in both PRE group. In histological findings of kidney tissue, thickening of GBM decreased in both PRE groups. Conclusions : The present study suggests that PRE is effective when treating mice with MN induced by cBSA. More clinical data and studies are to be done for efficient application.

Antibody changes in experimental anisakiasis were observed in 10 rabbits which were infected each with 10 Anisakis simplex larvae. The sera were collected before and on the 6th to the 95th day after the infection. Using crude saline extract of Anisakis larvae as antigen, specific IgM and IgG antibody levels were observed by ELISA and SDS-polyacrylamide gel electrophoresislimmunoblot. Levels of specific-IgM antibody were elevated from the 6th day, reached their peaks on the lIth day after the infection, and dropped thereafter. Serum levels of IgG antibody increased from the 6th day and reached their peak on the 26th day after the infection, and decreased gradually thereafter. When SDS-PAGE of the crude extract was done, at least forty-one SDS-polypeptide bands were recognized. Of them, IgM antibody reacted mainly to the bands of 168, 95, 74, 64, 51, 47 and 34 kDa while IgG antibody reacted strongly to 168, 92, 85, 64, 58, 52, 42 and 40 kDa bands. The crude extract showed negligible cross reactions with sera of other parasitic diseases and normal control. Key words: Anisakis simplex larvae, experimental anisakiasis, rabbit, antibody, ELISA, SDS- PAGE/immunoblot.

Detection of deep-seated abscesses is sometimes difficult with ultrasonogrpahy or computed tome graphy alone. Indium-111-labeled leukocyte has widely used in the localization of abscesses after introduction by Segal and Thakur in 1976. But there are some difficulties in using indium-111-oxine in our country because of hardness to get the radiopharmaceutical timely and long time for labeling leukocytes. So we peformed the indium-111-labeled leukocyte scan for establishment of the labeling procedure and clinical application. We labeled the mixed leukocytes from 36 ml of patient's blood using 4 ml of ACD solution, 7 ml of 6% hydroxyethyl starch solution $(HESPAN^{(R)})$, 1 mCi of indium-111 oxine, 5 ml of normal saline and centrifuge. It took about 2 hours for the preparation of radiolabeled leukocytes and attention for contamination was needed. The average injected dose of labeled mixed leukocytes was 465 uCi. The average number of injected leukocytes was $2.5\times10^8$ and the labeling ratio was $57{\pm}13%$ (Table 2, Fig. 5). These number and ratio were sufficient for the localization of abscess. About twenty per cent of indium was labeled to red blood cells and platelets (Fig. 6) and the half-life of injected radiolabeled leukocytes was 8.3 hours. Scan was performed in 9 patients who were suspected to have abscesses clinically or radiologically. Three patients were positive, in one patient who had abscess close to lower lumbar vertebrae was surgically drained and another 2 positive cases did not show abscess clearly on computed tomography, so only antibiotics were administrated and treated successfully. The negative 6 patients were improved without specific treatment. In conclusion, the use of indium-111 oxine labeled leukocytes for localization of abscesses were very specific and helpful in the decision of treatment considering its relatively simple labeling method, and could be easily performed providing timely supply of the radiopharmaceutical.

The effects of Aralia canescens and Phellodendron amurense(AP) extracts on the experimental diabetes in ICR mice were investigated. 96male ICR mice were induced diabetes mellitus by intrape-ritoneal streptozotocin injection(75mg/kg B.W.) and divided into two injection groups which are 5 day injection and 10 day injection group. Then, each injection group was subdivided into 8 groups of 6 animals repspectively. CIC served as control and CI1, CI2 and CI3 were treated with 50, 150, 250mg/kg B.W. of AP extracts powder in 0.9% NaCl solution. Animals of groups DIC, DI1, DI2 and DI3 were strepto-zotocin-induced diabetes. DIC served as diabetic control and the rest groups received 50, 150, 250mg/kg B.W of AP extracts powder in saline solution respectively. The body weight, liver and kiney weight changes and blood levels of glucose, cholesterol and triglyceride were measured. Thiobarbituric acid reactive substance(TBARS), and glutathione reductase(GR) and glutathione peroxidase(GPx) activities were also measured for determining antioxidant effects. AP extracts increased the body weight in diabetic groups. The liver and kidney weight/100g B.W. in DIC group were greater than those of normal ICR group but after AP extracts injection, liver and kidney weight were decreased significantly. These effects were more efficient at 10 days injection group. The total, LDL, VLDL cholesterol and triglyceride levels were significantly higher in DIC group and the extent of decrement responded to AP injection dose. The contents of TBARS and antioxidant enzyme activities were relatively decreased after AP extracts injection. These results suggest that the intraperitoneally administered AP extracts may have not only hypoglycemic effect but act as antioxidants by reducing lipid peroxidation.

Objectives: Hwangryunhaedok-tang (HH) is a representative heat clearing multiherb prescription. We evaluated the protective effect of HH against heat stress exposure in mice. Methods: Six weeks old ICR mice were used for this study. After $43^{\circ}C$ heat stress for 15 minutes, we evaluated the changes of motor activity and c-fos expression level to determine the proper heat stress and evaluation time. The subjects were divided into 4 groups (1. control group, 2. heat stress group with normal saline, 3. heat stress group with administration of 100 mg/kg, and 4. heat stress group with administration of 1000 mg/kg). After oral administration of HH once a day for 3 days, 2, 3, 4 groups were exposed to $43^{\circ}C$ heat stress for 15 minutes. Then, we evaluated the motor activity for 120 minutes and analyzed the c-fos expression using western blot. We investigated the effect of HH and its ingredients on c-fos expressions after heat stress. The mice were administrated HH, Scutellariae Radix, Coptidis Rhizoma, Phellodendri Cortex, and Gardeniae Fructus for 3 days. After one hour of last treatment, the mice were exposed to heat stress at $43^{\circ}C$ for 15 min. After two hours, the hypothalamus was dissociated and lysed to measure c-fos expression. Results: After oral administration of HH for 3 days, motor activity was recovered insignificantly. 100 mg/kg HH treatment reduced the c-fos expression after heat stress but insignificantly. Among the ingredients of HH, Coptidis Rhizoma and Scutellariae Radix treatment groups significantly reduced the c-fos after stress. Conclusions: These results show that Hwangryunhaedok-tang may be effective to reduce the heat stress response.

Vibriosis is an important septicemic bacterial disease that affects a variety of commercial fish species, including cultured Dicentrarchus labrax. Nanotechnology has become an important modern tool for fish diseases prevention. Furthermore, nanomaterials have the ability to prevent and treat fish diseases. The current study was aimed to identify the causative agent of massive mortality of D. labrax commercial farm in Alexandria, Egypt. Experimental infection and the median lethal dose (LD50) of pathogenic isolate were assessed. Also, the effect of ginger nanoparticles (GNPs) and Sacchromyces cerevisiae as feed additives for prevention of vibriosis in D. labrax was carried out. Similarly, the tissue immunstimulant genes, IL-1β and TLR2 were measured in the spleen of feeding groups. The clinical signs of naturally diseased D. labrax showed corneal opacity and paleness of gills with excessive mucous secretion. The post-mortem abnormalities were severe hemorrhage and adhesion of internal organs. After bacteriological isolation and identification, the causative agent of mortality in the current study was Vibrio alginolyticus. The LD₅₀ of V. alginolyticus was 1.5×10^5.4 CFU/ml. The experimentally infected D. labrax showed ulceration, exophthalmia and skin hemorrhages. The post-mortem findings of the experimentally infected D. labrax revealed internal hemorrhage, spleen darkness and paleness of liver. There is no mortality and 100% RPS in groups fed GNPs then injected with V. alginolyticus, in those fed a combination of GNPs and S. cerevisiae and a group fed normal diet then injected with physiological saline (control negative), respectively. Contrarily, there was 10% mortality and 87.5 RPS in the group fed S. cerevisae then injected with V. alginolyticus. On the other hand, the control positive group showed 79% mortality. The spleen IL-1β and TLR2 immunostimulant genes were significantly increased in groups of fish fed GNNP, S. cerevisiae and a combination of GNPs and S. cerevisiae, respectively compared to control group. The highest stimulation of those immunostimulant genes was found in the group fed a combination of GNPs and S. cerevisiae, while fish fed S. cerevisiae had the lowest level. Dietary combination of GNPs and S. cerevisiae was shown to be efficient in preventing of vibriosis, with greatest stimulation of spleen IL-1β and TLR2 immunostimulant genes.

Background: Postoperative nausea and vomiting (PONV) frequently occurs following bimaxillary orthognathic surgeries. Compared to opioids, Nefopam is associated with lower incidences of PONV, and does not induce gastrointestinal tract injury, coagulopathy, nephrotoxicity, or fracture healing dysfunction, which are common side effects of Nonsteroidal anti-inflammatory drugs. We compared nefopam- and fentanyl-induced incidence of PONV in patients with access to patient-controlled analgesia (PCA) following bimaxillary orthognathic surgeries. Methods: Patients undergoing bimaxillary orthognathic surgeries were randomly divided into nefopam and fentanyl groups. Nefopam 120 mg or fentanyl $700{\mu}g$ was mixed with normal saline to a final volume of 120 mL. Patients were given access to nefopam or fentanyl via PCA. Postoperative pain intensity and PONV were measured at 30 minutes and 1 hour after surgery in the recovery room and at 8, 24, 48, and 72 hours after surgery in the ward. The frequency of bolus delivery was compared at each time point. Results: Eighty-nine patients were enrolled in this study, with 48 in the nefopam (N) group and 41 in the fentanyl (F) group. PONV occurred in 13 patients (27.7%) in the N group and 7 patients (17.1%) in the F group at 8 hours post-surgery (P = 0.568), and there were no significant differences between the two groups at any of the time points. VAS scores were $4.4{\pm}2.0$ and $3.7{\pm}1.9$ in the N and F groups, respectively, at 8 hours after surgery (P = 0.122), and cumulative bolus delivery was $10.7{\pm}13.7$ and $8.6{\pm}8.5$, respectively (P = 0.408). There were no significant differences in pain or bolus delivery at any of the remaining time points. Conclusion: Patients who underwent bimaxillary orthognathic surgery and were given nefopam via PCA did not experience a lower rate of PONV compared to those that received fentanyl via PCA. Furthermore, nefopam and fentanyl did not provide significantly different postoperative pain control.

In this study, a self-made customized phantom was used to quantitatively measure the change in CT number and noise according to the change of pitch. In order to acquire an image using the phantom, the inside of the phantom was filled with sterile distilled water. Inside the glass tube, a solution obtained by diluting the ratio of normal saline and contrast medium to 100%(NS), 400:1, 200:1, 100:1, 50:1, respectively, was placed and imaged. At this time, the pitch was divided into steps of 0, 0.35, 0.7, 1.05, and 1.4 for each dilution ratio of the solution and imaged, respectively. One-way ANOVA analysis were performed to verify whether the mean of the CT number and noise values measured in all ROIs by dilution ratio showed a significant difference according to the change in pitch. As a result of the experiment, there was no statistically significant difference in the change of the CT number according to the change in the pitch for each dilution ratio, but the noise value tended to increase with the increase of the pitch, and showed a statistically significant difference. In the spiral image acquisition of CT, noise can be changed to a significant level depending on the pitch. Therefore, it will be necessary to set the quality evaluation items and criteria for CT images using the spiral image acquisition method.
