To investigate effects of A. gmelini on the 14-day CCl$_4$induced hepatotoxicity, extracts were prepared in 3 ml saline at the dose of 5,000 mg/kg b.w. to administer orally once daily. Each concentration (5：5, 2：5 : 7.5, 1：9, CCl$_4$: olive oil v/v) of CCl$_4$was orally administered with 2.5 ml/kg b.w., During the experiment, halves of the rats were sacrificed every 7 day and hemanalysis was done. On the 7th day, hemanalysis showed following recovery values; AST 52.6∼61.4％, ALT 55.9∼86.1％, ALP 46.0∼70.9%, BUN 75.7∼100.0< ％, TBIL 55.2∼96.1％, TCHO 38.0∼63.7％, and TG 55.2∼96.0％. On the 14th day, recovery values of each treatment were GOT 37.7∼43.1％, GPT 19.8∼45.9％, ALP 58.1∼95.9％, BUN 57.6∼100.0< ％, TBIL 78.6∼100.0< ％, TCHO 56.9∼100.0< ％, and TG 10.0∼5l.2%. By histological examination of liver, hydropic degeneration, fatty change, lipid accumulation and necrosis were also recovered by administration of A. gmelini extract.

This study aimed to investigate the protective effect of Solanum nigum Linne total extract (SNT), Solanum nigum Linne leaf extract (SNL), Solanum nigum Linne root extract (SNR) on liver injury induced by Lipopolysaccharide(LPS) in Sprague-Dawley rats. SNT, SNL, SNR of 100 mg/kg concentration was intraperitoneally administered into rats at dose of 1.5 ml/kg for 20 days. on the day 1.5 ml/kg of LPS was injected. Four hours later, they were anesthetization with ether and dissected. Glutamate oxaloacetate transaminase (GOT), glutamate pyruvate transaminase (GPT) were measured in serum and superoxide dismutase (SOD), catalase and glutathione peroxidase (GPX) were measured in liver homogenate. SNT, SNL, SNR extract inhibited GOT and GPT activities in LPS-induced rats, whereas increased SOD, Catalase and GPX activity in liver tissue of LPS-induced rats. These suggested that SNT, SNL, SNR could be used for functional beverage.

Background: To compare the effects of adding two different doses of dexamethasone on the duration and quality of the fascia iliaca block in patients undergoing proximal femoral fracture surgery. Methods: A total of 60 patients (age 18-70 years) undergoing proximal femoral nailing surgery under spinal anesthesia were given fascia iliaca block after random assignment to one of the two groups: Group H received an injection of levobupivacaine (0.5%) 28 ml with 2 ml (8 mg) dexamethasone, and Group L received an injection of levobupivacaine (0.5%) 28 ml with dexamethasone 1 ml (4 mg) with 1 ml normal saline. Assessment of the duration of analgesia and the total tramadol requirement over 48 hours were noted after a successful block. Results: The duration of analgesia was found to be significantly longer in Group H ($17.02{\pm}0.45h$) than in the Group L patients ($14.29{\pm}0.45h$) with a p-value of 0.000. Postoperative analgesic requirement (amount of tramadol in mg) was significantly higher in Group L (Q2: 200.0; IQR: 100.0, 200.0) as compared to Group H (Q2: 100.0; IQR: 100.0, 200.0) with a p-value of 0.034. No patient showed any sign of neurotoxicity. Conclusions: Dexamethasone, in a dose of 8 mg, is superior to 4 mg when used as an adjuvant with levobupivacaine in the FIB. Though both prolonged analgesia and were effective in reducing oral/intravenous analgesics, 8 mg dexamethasone can be recommended as a more efficacious adjuvant to local anesthetics in the FIB.

Three hundred gram of Korean ginseng root was extracted with 95% ethanol on a boiling water bath for about 300 hr. Evaporation of alcohol yieled 50.2g of dark brown residue which was used by dissolving 4 mg of the residue in 1 ml of physiological saline. The ginseng group and the saline group received each day 0.5 ml per 100 g body weight of ginseng extract and physiological saline, respectively. Both the ginseng and saline group with stress were exposed to positive radial acceleration (1∼29g), cold (5$^{\circ}C$, 0$^{\circ}C$ &-10$^{\circ}C$) and heat (35$^{\circ}C$) environment, and surgical stress. After termination of the last stress, the tolerance, body weight, visceral organ weight, basal metabolism rate, rectal temperature, the number of erythrocyte and leucocyte, hemoglobin level, hematocrit ratio, total serum protein content and it's fraction and the content of adrenal ascorbic acid in the experimental animal exposed to stress were measured and at the corresponding periods, the same measurements were also carried out with the ginseng and the saline groups without stress exposure (serving as control). Results obtained were as follows. 1. Administration of ginseng does depressed the decrease of the tolerance, body weight, visceral organ weight, basal metabolism rate, the number of erythrocyte, hemoglobin value, hematocrit ratio and the A/G ratio in the mice and rats exposed to various stress. 2. The change of the rectal temperature, eosinophile counts, total serum protein content and the content of adrenal ascorbic acid of ginseng group that exposured to various stress facilitates the reaction to, and accelerates the recovery from the stress. 3. Even after hypophysectomy which served the link between the central and the peripheral portion of the stress mechanism, the adrenal ascorbic acid content of ginseng group decreased significantly more than that of the saline group 30 min. after administration of ACTH, while the value approached the normal level significantly closer in the ginseng group than in the saline group 1 and 2 hr after ACTH administration. Judging from the above results, it is concluded that administration of ginseng extract tolerated the experimental animals under the environment of stressfu1 stmuli, although the ginseng has no significant influence upon the stress mechanism in the absence of stressful stimuli. The site of action of the ginseng appears to be in the peripheral portion of the stress mechanism.

Background: The purpose of this study was to evaluate the effect of dexamethasone or dexmedetomidine added to ropivacaine on the onset and duration of ultrasound-guided axillary brachial plexus blocks (BPB). Methods: Fifty-one ASA physical status I-II patients with elective forearm and hand surgery under axillary brachial plexus blocks were randomly allocated to receive 20 ml of 0.5% ropivacaine with 2 ml of isotonic saline (C group, n = 17), 20 ml of 0.5% ropivacaine with 2 ml (10 mg) of dexamethasone (D group, n = 17) or 20 ml of 0.5% ropivacaine with 2 ml ($100{\mu}g$) of dexmedetomidine (DM group, n = 17). A nerve stimulation technique with ultrasound was used in all patients. The onset time and duration of sensory blocks were assessed. Results: The duration of the sensory block was extended in group D and group DX compared with group C (P < 0.05), but there was no significant difference between group D and group DX. However, there were no significant differences in onset time in all three groups. Conclusions: Dexamethasone 10 mg and dexmedetomidine $100{\mu}g$ were equally effective in extending the duration of ropivacaine in ultrasound-guided axillary BPB with nerve stimulation. However, neither drug has significantly effects the onset time.

Purpose: This study was conducted to investigate the muscle anti-fatigue effects of Allii tuberosi semen after long term administration. Materials and Methods: 4-6 weeks old ICR mice were used in this study and we administered the water soluble extracts of Allii tuberosi semen in the concentration of 1, 10 and 100mg/0.3ml to each 5 mice (ATS group) and same volume of normal saline was administered to 5 mice (control group) once a day for 90 or 120 days. After the administration we performed the swimming exercise test and the grip strength test. And we measured the concentration of glucose and the activity of lactate dehydrogenase in plasma regarded as biochemical indicator related with the muscular fatigue. Results: In swimming exercise test, all ATS groups showed increased time compared with relative control group after 90 days administration. But after 120 days adminstration 10 and 100mg/0.3ml ATS groups showed increased results. In grip strength test, all ATS group increased grip strength after 90 days administration and 10mg/0.3ml ATS group showed increased result after 120 days administration. All the results of plasma glucose didn't showed statistically significant difference after 90 and 120 days administration. In the plasma concentration of activity level of lactate dehydrogenase, 1mg/0.3ml and 10mg/0.3ml ATS groups showed decreased concentration compared with relative control group after 90 days administration. But after 120 days adminstration 1mg/0.3ml ATS groups showed decreased results. Conclusion: From this study we could find the anti-fatigue effect of Allii tuberosi semen in the muscle strength related test.

Background : Forceps biopsy, bronchial brushing, and bronchial washing are used in conjunction with bronchoscopy to provide specimens for histologic and cytologic analysis in patients with suspected lung cancer. This study was performed to evaluate how many times brushing should be done and how much fluid should be used during bronchial washing for increasing diagnostic yield, and to evaluate which combination of these procedures gives the highest diagnostic yield. Methods : Forty patients, with suspected lung cancer, who had bronchoscopically visible lesions were enrolled in this prospective study. During one bronchoscopic examination four forceps biopsies, four bronchial brushings, and bronchial washing were done in all patients. The patients were divided into four groups by the amount of normal saline used for bronchial washing; group I, 10 ml ; group II, 20ml ; group III 30ml, and group IV, 40ml. We analyzed the results in 36 patients confirmed as lung cancer. Results : The diagnostic sensitivity of bronchial washing before and after forceps biopsy and bronchial brushing were 36% and 28%, respectively. The cumulative diagnostic sensitivity of bronchial washing was 47% and significantly higher than that of bronchial washing before or after forceps biopsy and bronchial brushing (p<0.05). The diagnostic sensitivity of bronchial washing with saline of 30ml was significantly higher than that of bronchial washing with saline of 10ml or 20ml (p<0.05). The diagnostic sensitivity of the first brushing was 75%, the second brushing 78%, the third brushing 83%, and the fourth brushing 67%. With repeated brushing up to three times, the diagnostic sensitivity increased to 92% (p<0.05). However, inclusion of the fourth brushing did not give a further increase of the diagnostic sensitivity. The diagnostic sensitivity of forceps biopsy was 86%. The diagnostic sensitivities of forceps biopsy by the type of bronchial lesion were as follows: tumor, 88%; infiltration, 67%; infiltration with nodularity, 80%; and collapse, 100%. The combination of forceps biopsy and bronchial washing gave a diagnostic sensitivity of 89%. The diagnostic sensitivity of combining forceps biopsy with bronchial brushing was 97%. Addition of bronchial washing did not increase the diagnostic yield over forceps biopsy and bronchial brushing. Conclusion : In patients with central lung cancer, forceps biopsies and repeated brushings up to three times should be done for maximal diagnostic yield.

Background: Nefopam is a non-opioid, non-steroidal analgesic drug with fewer adverse effects than narcotic analgesics and nonsteroidal anti-inflammatory drugs, and is widely used for postoperative pain control. Because nefopam sometimes causes side effects such as nausea, vomiting, somnolence, hyperhidrosis and injection-related pain, manufacturers are advised to infuse it slowly, over a duration of 15 minutes. Nevertheless, pain at the injection site is very common. Therefore, we investigated the effect of warmed carrier fluid on nefopam injection-induced pain. Methods: A total of 48 patients were randomly selected and allocated to either a control or a warming group. Warming was performed by diluting 40 mg of nefopam in 100 ml of normal saline heated to $31-32^{\circ}C$ using two fluid warmers. The control group was administered 40 mg of nefopam dissolved in 100 ml of normal saline stored at room temperature ($21-22^{\circ}C$) through the fluid warmers, but the fluid warmers were not activated. Results: The pain intensity was lower in the warming group than in the control group (P < 0.001). The pain severity and tolerance measurements also showed statistically significant differences between groups (P < 0.001). In the analysis of vital signs before and after the injection, the mean blood pressure after the injection differed significantly between the groups (P = 0.005), but the heart rate did not. The incidence of hypertension also showed a significant difference between groups (P = 0.017). Conclusions: Use of warmed carrier fluid for nefopam injection decreased injection-induced pain compared to mildly cool carrier fluid.

Objectives : The purpose of this study was to investigate the effect of Gentianae Radix on neurogenesis and apoptosis in ethanol- induced newborn rats hippocampus dentate gyrus. Methods : In vivo, laboratory animals were divided into three groups; Normal group(N), Control group(C) and Treated group (TG)(n=7 for each group). N were treated saline daily for five days. C were treated 1.5 g/kg ethanol and saline daily for five days. TG were treated 1.5 g/kg ethanol and 300 mg/kg Gentianae Radix daily for five days. BrdU(5-bromo-2-deoxyuridine) assay was used to test neurogenesis in the dentate gyrus. And TUNEL(Terminal deoxynucleotidyl transferase dUTP nick end labeling) assay was used to test apoptosis in the dentate gyrus. Three groups were measured body weight, serum ethanol concentration, BrdU-positive cells and TUNEL-positive cells in the dentate gyrus. In vitro, MTT(3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay was used to test viability in SK-N-MC cells. BrdU assay was used to test neurogenesis in SK-N-MC cells. DNA fragmentation and caspase-3 enzyme activity assay were used to test apoptosis in SK-N-MC cells. And treated ethanol and Gentianae Radix of all in vitro tests were made various concentration. Results : In vivo, Gentianae Radix modulated ethanol-induced neurogenesis and apoptosis in newborn rats hippocampus dentate gyrus. In vitro, TG 100 ${\mu}g/ml$ have significantly modulated ethanol-induced neurogenesis and apoptosis in SK-N-MC cells. And only TG 100 ${\mu}g/ml$ have significantly protected SK-N-MC cells from ethanol-induced cytotoxicity. Conclusions : Gentianae Radix may have the effect that modulated ethanol-induced neurogenesis and apoptosis in SK-N-MC cells.
