Objectives : We examined the effects of electroacupuncture on the cholecystokinin-octapeptide-induced acute pancreatitis in rats. Methods : Rats were administered with $75{\mu}g/kg$ cholecystokinin-octapeptide subcutaneously three times (1, 3 and 5h after shaving) for 5days. Three days after finishing cholecystokinin-octapeptide administration, high frequency electroacupuncture (100Hz) and low frequency electroacupuncture (2Hz) were applied to acupoint equivalent to ST36 (Zusanli) for 7 days. The author determined the pancreatic weight/body weight ratio, the levels of pancreatic heat shock protein HSP60 and HSP72. The author also assay the secretion of ${\beta}-amylase$, lipase and pro-inflammatory cytokines in serum. Repeated cholecysokinin-octapeptide treatment resulted in the typical laboratory and morphological changes of experimentally induced pancreatitis. Results : Eelectroacupuncture significantly decreased the pancreatic weight/body weight ratio in cholecystokinin-octapeptide-induced acute pancreatitis, increased the pancreatic levels of HSP60 and HSP72, and decreased ${\beta}-amylase$ and lipase levels in cholecystokinin-octapeptide-induced acute pancreatitis. Additionally, the secretion of $Interleukin-1{\beta}$ and tumor necrosis $factor-{\alpha}$ was decreased in the animals treated with electroacupuncture. Conclusion : These results suggest that electroacupuncture may have protective effects against cholecystokinin-octapeptide-induced acute pancreatitis.

Objectives : In this study, we investigated the effects of Daehwangmokdanpitang-gagambang(DMG) on treatment for cholecystokinin-octapeptide(CCK)-induced acute pancreatitis(AP) in rats. Methods : Male Wistar rats weighing 200 to 250 g were divided into three groups. The first was normal untreated group, the second was in treatment with DMG group; DMG was administered orally, followed by 75 ${\mu}g/kg$ CCK subcutaneously three times, after 1, 3 and 5 h. This whole procedure was repeated for 5 days. The third was in treatment with saline group, the protocol was the same as in treatment group with DMG. We determined the pancreatic weight/body weight ratio, the levels of pancreatic HSP60, HSP72, ERK, p38 MAPK and the secretion of pro-inflammatory cytokines. Repeated CCK treatment resulted in the typical laboratory and morphological changes of experimentally induced pancreatitis. Results : DMG was significantly decreased the pancreatic weight/body weight ratio in CCKinduced AP and DMG increased HSP60 and HSP72 compared with CCK-induced AP. DMG suppressed ERK and p38 MAPK activation. Additionally, the secretion of $IL-1{\beta}$ and $TNF-{\alpha}$ and the levels of amylase and lipase were lower than that saline. Conclusions : DMG has an effect to treatment for CCK-induced AP.

This study was performed in order to evaluate the neuroprotective effect of Boyanghwano-tang (BYT) water extract on intracerebral hemorrhage (ICH). ICH was induced by the stereotaxic intrastriatal injection of bacterial collagenase type IV in Sprague-Dawley rats. BYT was orally given once a day for 3 days after ICH. Hematoma volume and percentage edema were examined. As imflammatory markers, myeloperoxidase (MPO)-positive neutrophils infiltration and iNOS expression in the peri-ICH regions were examined using immunohistochemistry. As cellular damage markers, c-Fos, Bax, and HSP72 positive cells in the peri-ICH regions were measured also. BYT significantly reduced the hematoma volume and percentage edema of the ICH-induced rat brain. In the peri-hematoma regions, BYT significantly reduced MPO-positive neutrophil infiltration and iNOS expression of the ICH-induced rat brain. Additionally, BYT significantly reduced c-Fos, Bax, and HSP72 positive cells in the peri-hematoma regions of the ICH-induced rat brain. These results suggest that BYT plays a neuroprotective role against ICH through suppression of inflammatory responses, apoptosis and cellular damage.

Objectives : This study was performed to evaluate the effects of root of Cibotii rhizoma(CR) ethanol extract on the tissue and neuronal damage of the spinal cord injury(SCI). Methods : SCI was induced by mechanical contusion following laminectomy of 10th thoracic vertebra in Sprague-Dawley rats. CR was orally given once a day for 7 days after SCI. Tissue damage and nerve fiber degeneration were examined with cresyl violet and luxol fast blue(LFS) histochemistry. HSP72(as neuronal damage marker), MAP2(as nerve fiber degeneration marker), c-Fos(immediate early gene), and Bax(pro-apoptotic molecule) expressions were examined using immuno-histochemistry. Individual immuno-positive cells expressing HSP72, MAP2, c-Fos and Bax were observed on the damaged level and the upper thoracic and lower lumbar spinal segments. Results : 1. CR reduced degeneration of nerve fibers and motor neuron shrinkage in the ventral horn of the lower lumbar spinal segment, but generally it did not seem to ameliorate the tissue injury following SCI. 2. CR reduced demyelination in the ventral and lateral funiculus of the lower lumbar spinal segment. 3. CR reduced HSP72 expression on the neurons in the peri-central canal gray matter adjacent to the damaged region. 4. CR strengthened MAP2 expression on the motor neurons in the ventral horn and on nerve fibers in the lateral funiculus of the lower lumbar spinal segment. 5. CR reduced c-Fos positive cells in the peri-lesion and the dorsal horn of the damaged level and in the ventral horn of the lower lumbar spinal segment. 6. CR reduced Bax positive cells in the peri-lesion and the dorsal horn of the damaged level and in the ventral horn of the lower lumbar spinal segment. Conclusions : These results suggest that CR plays an inhibitory role against secondary neuronal damage and nerve fiber degeneration. following SCI.

Purpose : $Henoch-Sch\"{o}nlein$ purpura(HSP) is a systemic vasculitis that involves multiple organs, especially the kidney, which is the most important organ in determining the prognosis of the disease. The morbidity of HSP nephritis in adults is low and there have been little research done on its clinical course so far. Therefore, we have compared the clinical course of HSP nephritis in children and adults in Korea. Methods : We retrospectively analyzed 81 cases of HSP nephritis in children younger than 15 years of age, and 25 cases of adults older than 15 years of age who were admitted to Yonsei University Medical College Severance Hospital from Jan. 1986 to May 2003. Results : The male to female ratio was 1.5 : 1 in children and 1.3 : 1 in adults. The incidence of HSP nephritis for both age groups was found to be increased during the autumn and winter. Infection was the predisposing factor in 39 cases(48.1%) of children, 16 cases(64.0%) of adults, and drugs were the predisposing factor in 8 cases(9.9%) of children and 4 cases (16.0%) of adults. All patients initially presented with microscopic hematuria. Thirteen cases (16.0%) of children and 7 cases(28.0%) of adults initially showed proteinuria of nephrotic range. Thirty four cases(42.0%) of children and 4 cases(16.0%) of adults showed normal urinalysis after treatment. Asymptomatic urinary abnormalities were found in 41 cases(50.6%) of children and 18 cases(72.0%) of adults. Complications such as nephrotic syndrome and hypertension were found in 3 cases(3.7%) of children and 2 cases(8.0%) of adults. Three children(3.7%) and 1(4.0%) adult required dialysis or renal transplantation. Follow-up renal biopsies were performed on 21 children, of whom 10 cases(47.6%) did not show any histologic change, 9 cases(42.9%) showed low grade changes, and 2 cases(9.5%) showed high grade changes. Prognosis was gloomy when proteinuria of nephrotic range and high grade of abnormal histology were present at diagnosis, and there was no significant difference between the two groups(P<0.05) Conclusion : This study showed that there was no difference in terms of the clinical features and courses between the children and adults with HSP nephritis. Proteinuria of nephrotic range and the severity of abnormal histologic changes at diagnosis were found to be associated with a bad prognosis, therefore we recommend that patients with these features require long term follow-up and management.

Objectives: This study demonstrates the neurological effects of Bojungikki-tang and Bojungikki-tang-gamibang on the focal cerebral ischemia of rats with ischemic damage caused by middle cerebral artery occlusion (MCAO). Methods: Rats were treated with Bojungikki-tang and Bojungikki-tang-gamibang extracts for about five days after MCAO, and the size and volume of cerebral infarction and the ratio of cerebral edema were observed. From the immunohistochemical view, significant changes of outbreak of Bax, Bcl-2, c-Fos, HSP72, and iNOS were observed in the brain tissues. Results: Bojungikki-tang repressed only brain edema and iNOS revelation led by focal cerebral ischemia, when considering significance. In contrast, Bojungikki-tang-gamibang demonstrated significant suppression of cerebral infarction, brain edema, Bax, c-Fos, HSP72, and iNOS induced by focal cerebral ischemia. Conclusions: Bojungikki-tang is considered functional treatment for cerebral ischemic damage; it can be effective to relieve secondary brain edema and immune response. Bojungikki-tang-gamibang can have a direct function to alleviate brain infarct and to control the natural death of nerve cells which cerebral ischemic damage brings about.

This study evaluated neuroprotective effect of Sunghyangjungki-San (SHS) on the focal cerebral ischemia. The rats were induced infarct in cerebral cortex and caudoputamen by using temporal occlussion of the middle cerebral artery (MCAO), then water extract of SHS was treated for MCAO rats. Neuroprotective effect was evaluated by neurological score, infarct sizes and total volume, positive neurons against Bax, Caspase-3, HSP-72, and $HIF-1{\alpha}$ in infarct area with immunohistochemistry. The results obtained were as follows: Treatment of SHS improved neurological score of MCAO rats, but there was not a statistical significance. Treatment of SHS reduced significantly infarct sizes in the brain sections of MCAO rats. Treatment of SHS reduced significantly total volume of infarct of MCAO rats. Treatment of SHS reduced significantly Bax positive neurons in penumbra of cerebral cortex of MCAO rats. Treatment of SHS reduced significantly Caspase-3 positive neurons in caudoputamen and penumbra of cerebral cortex of MCAO rats. Treatment of SHS reduced significantly HSP-72 positive neurons in penumbra of cerebral cortex of MCAO rats. Treatment of SHS reduced significantly $IF-1{\alpha}$ positive neurons in penumbra of cerebral cortex of MCAO rats.

Gamma (${\gamma}$)-oryzanol is a substance abundant in rice, which is widely cultivated in Asian countries. In this study, we evaluated the effect of ${\gamma}$-oryzanol treatment on proliferation and apoptosis of AGS human gastric carcinoma cells. AGS cells were treated with ${\gamma}$-oryzanol for 72 h in a dose dependent manner. Treatment of ${\gamma}$-oryzanol (50, 100, and $200{\mu}g/mL$) resulted in decreased AGS cell proliferation and increased number of cells in the sub-G1 population. Additionally, apoptotic cells were investigated by annexin V staining and mitochondrial membrane potential assays. Our results indicated that ${\gamma}$-oryzanol treatment increased the number of annexin V-positive cells and depolarized cells. This demonstrated that ${\gamma}$-oryzanol is effective for the induction of apoptosis in AGS cells. We next examined the expression of promising anticancer drug target molecules, including PTEN and HSP90. We found that treatment of ${\gamma}$-oryzanol induced the expression of PTEN in AGS cells. Under the same treatment conditions, ${\gamma}$-oryzanol reduced the expression of HSP90 in AGS cells. These results suggest that ${\gamma}$-oryzanol-induced apoptosis was accompanied by changes in regulation of PTEN and HSP90 in AGS cells. Taken together, ${\gamma}$-oryzanol could be used as a functional substance for the prevention of gastric cancer.

Objectives: In this study the authors investigated effects of the ethanolic extract of Rhodjola Rosea(HKC) on fatigue and hypothalamic IEG expression in rat forced swimming(FS) model. Methods: Sprague-Dawley rats were administered HKC extract(25 mg/100g, p.o.) for 3 days prior to FS, some rats underwent 10 min FS and others exhaustive forced swimming(EFS). In addition, other rats were administered extract at different times after EFS over 3 consecutive days. Results: When HKC administered before 10 mins of FS, serum actate dehydrogenase(LDH) and creatine phosphokinase(CPK) activities were significantly lower than control group. When HKC administered prior to EFS, blood lactate was significantly lower versus control group. When HKC was administered after EFS, blood lactate(at 6 and 24 hours after EFS) were significantly lower and serum LDH, CPK activities(at 24 hours after EFS) were significantly lower versus control group. When HKC was administered after EFS, c-Fos positive neurons in hypothalamic periventricular area(PVA), medial part(mPVN) and anterior hypothalamic nucleus caudal part(AHC) were significantly lower at 24 hours after EFS than in control group. HSP-72 positive neuron numbers in hypothalamus were significantly lower at 24 hours after EFS than in control group. Finally, when HKC was administered prior to 10 mins FS, HIF-$1{\alpha}$ expression in the gastrocnemius muscle was significantly increased. Conclusions: These results suggest that HKC extract has an anti-fatigue effect, and it reduces neuronal cell stress responses induced by physical stress by having a beneficial effect on lactate metabolism.
