  • The purpose of this study is to define the normal findings of cerebrospinal fluid (CSF) of the clinically healthy Beagle dogs and to provide basic information in diagnosis of neurologic disorders. CSF obtained from 13 clinically healthy dogs was examined for total and differential cell counts, total protein concentration, glucose and lactate dehydrogenase (LDH) concentration, specific gravity, turbidity, and protein electrophoresis. On gross examination, CSF samples evaluated were clear and colorless. Few red blood cells and nucleated cells were present. The mean concentration of glucose and LDH examined were 65.8 mg/dl and 2.7 mg/dl, respectively. The cellular components of CSF samples based on differential counts were monocytes (41.9%), activated macrophages (35.8%), lymphocytes (20.0%), neutrophils (1.6%), and eosinophils (0.7%). The fractions of electrophoretic protein in CSF were albumin (52.7%), alpha-globulin (16.5%), beta-globulin (24.8%), and gamma-globulin (3.0%). Results of albumin quota were ranged from 0.15 to 0.38. In conclusion, this study provided normal composition of CSF in Beagle dogs.

  • Chrysanthemum indicum is widely used to treat immune-related and infectious disorders in East Asia. C. indicum flower oil contains 1,8-cineole, germacrene D, camphor, ${\alpha}$-cadinol, camphene, pinocarvone, ${\beta}$-caryophyllene, 3-cyclohexen- 1-ol, and ${\gamma}$-curcumene. We evaluated the safety of C. indicum flower oil by conducting acute oral toxicity, bone marrow micronucleus, and bacterial reverse mutation tests. Mortality, clinical signs and gross findings of mice were measured for 15 days after the oral single gavage administration of C. indicum flower oil. There were no mortality and clinical signs of toxicity at 2,000 mg/kg body weight/day of C. indicum flower oil throughout the 15 day period. Micronucleated erythrocyte cell counts for all treated groups were not significantly different between test and control groups. Levels of 15.63~500 ${\mu}g$ C. indicum flower oil/plate did not induce mutagenicity in S. Typhimurium and E. coli, with or without the introduction of a metabolic activation system. These results indicate that ingesting C. indicum flower oil produces no acute oral toxicity, bone marrow micronucleus, and bacterial reverse mutation.

  • Two new cyclic depsipeptides wewakamide A (1) and guineamide G (2) have been isolated from the marine cyanobacterium Lyngbya semiplena and Lyngbya majuscula, respectively, collected from Papua New Guinea. The amino and hydroxy acid partial structures of wewakamide A and guineamide G were elucidated through extensive spectroscopic techniques, including HR-FABMS, 1D $^1H$ and $^{13}C$ NMR, as well as 2D COSY, HSQC, HSQC-TOCSY, and HMBC spectra. The sequence of the residues of wewakamide A was determined through a combination of ESI-MS/MS, HMBC, and ROESY. Wewakamide A possesses a ${\beta}$-amino acid, 3-amino-2-methylbutanoic acid (Maba) residue, which has only been previously identified in two natural products, guineamide B (3) and dolastatin D (4). Although both new compounds (1,2) showed potent brine shrimp toxicity, only guineamide G displayed significant cytotoxicity to a mouse neuroblastoma cell line with $LC_{50}$ values of 2.7 ${\mu}M$.

  • This study was designed to determine the protective effect of Rumex Aquaticus Herba extracts containing quercetin-3-${\beta}$ -D-glucuronopyranoside (ECQ) on experimental reflux esophagitis. Reflux esophagitis was induced by surgical procedure. The rats were divided into seven groups, namely normal group, control group, ECQ (1, 3, 10, 30 mg/kg) group and omeprazole (30 mg/kg) group. ECQ and omeprazole groups received intraduodenal administration. The Rats were starved for 24 hours before the experiments, but were freely allowed to drink water. ECQ group attenuated the gross esophagitis significantly compared to that treated with omeprazole in a dose-dependent manner. ECQ decreased the volume of gastric juice and increased the gastric pH, which are similar to those of omeprazole group. In addition, ECQ inhibited the acid output effectively in reflux esophagitis. Significantly increased amounts of malondialdehyde (MDA), myeloperoxidase (MPO) activity and the mucosal depletion of reduced glutathione (GSH) were observed in the reflux esophagitis. ECQ administration attenuated the decrement of the GSH levels and affected the MDA levels and MPO activity. These results suggest that the ECQ has a protective effect which may be attributed to its multiple effects including anti-secretory, anti-oxidative and anti-inflammatory actions on reflux esophagitis in rats.

  • The purpose of this study was is to investigate the arthritis treatment and prevention of the effects the herbral administration to experimental animals induces arthritis 4 weeks for medicinal herbs (Scutellaria baicalensis Georgi, Acanthopanacis cortex, Achyranthis Radix). To investigate the prevention of histopathological examination and molecular biological examinations for arthritis improvement in vivo New Zealand, white rabbits were divided into a normal (Normal, n = 7), or a collagen-induced arthritis (CIA, n = 7), or a collagenase injection and medicinal herbs (SAA, n = 7). It was confirmed that induced arthritis was treated with Gross examination, and the measurement of average arthritis index (MAI) and improved arthritis by medicinal herbs. TNF-${\alpha}$ and IL-$1{\beta}$ were significantly increased in the CIA and SAA groups, compared to the normal group (p < 0.05). MMP-1 and TIMP-2 were significantly increased in the CIA, compared to the other groups (p < 0.05). MMP-1 and TIMP-2 were significantly decreased in the SAA group, compared to the CIA group (p < 0.05). As a result, Herbal administration used in this study might be able to help in the treatment of arthritis induced by inflammatory and immunosuppressive effects, that which can be expected.

  • Objectives: This study was performed to investigate the effects of Gagamsosokmyeong-tang(Jiajianxiaoxuming-tang) on the monosodium iodoacetate(MIA) induced early state osteoarthritis in rats. Methods: Osteoarthritis was induced by injection of MIA(0.25 mg) into knee joints of rats. Osteoarthritis rats were divided into control(n=8) and treated=8 group respectively, Control group was taken distilled water and treated group was taken extracts of Gagamsosokmyeong-tang(Jiajianxiaoxuming-tang) by orally for 20 days. Body weight was measured at 0, 5, 10, 15, 20 days after MIA injection. At the end of experiment, gross and histopathological examination on the articular cartilages of the knee joints were performed. Proteoglycan(PG) content of articular cartilages were analysed by safranine O staining method. The content of tumor necrosis $factor-{\alpha}(TNF-{\alpha})$, $interleukin-1{\beta}(IL-1{\beta})$ in synovial fluids were analysed by enzyme-inked inmunosorbent assay(ELISA) method. And also cycloxygenase-2(COX-2), matrix metalloproteinase 3(MMP-3), inducible nitric oxide synthase(iNOS), calpain immunochistochemical examination on the knee joints were performed. Results: PG content in articular cartilages of the treated group was significantly increased compared with control group. Histopathological osteoarthritic score of the treated group was significantly decreased compared with control group. $TNF-{\alpha}$ content in synovial fluids, expression of iNOS and calpain in synovial membrane of the treated group were significantly decreased compared with control group. But body weight, $1L-1{\beta}$ content in synovial fluids, expression of iNOS and MMP-3 of the treated group were not significantly changed compared with control group. Conclusions: On the basis of these results, we conclude that Gagamsosokmyeong-tang(Jiajianxiaoxuming-tang) has anti-arthritic effects on the MIA induced early stage osteoarthritis in rats.

  • Objectives : The water extract of Sopung-tang (SPT) has been traditionally used in the treatment of acute stroke in Oriental Medicine. Pro-inflammatory cytokines play a critical role in the onset of post-ischemic inflammatory cascades. The present study was designed to investigate the effects of SPT on pro-inflammatory cytokine production in a photothrombotic ischemia mouse model. Methods : After SPT oral administration to the mice for five days, with using Rose Bengal and cold light, photothrombotic ischemia lesion was induced in stereotactically held male BALB/c mice. Also, results including, gross finding lesion size, histopathological finding changes, and inflammatory cytokine expression changes from the photothrombotic ischemia mouse model were observed. Results : The photothrombotic ischemia lesion was decreased by the oral injection of SPT. Also, SPT inhibited the expression of TNF-$\alpha$, IL-$1{\beta}$, IL-6, the active form of caspase-3 protease, and transglutaminase-2 in the photothrombotic ischemia lesion. Conclusions : These results suggest that SPT protects the ischemic death of brain cells through suppression of the production of anti-inflammatory cytokines and catalytic activation of caspase-3 protease in the photothrombotic ischemia mouse model.

  • This study was to investigate the effects of Bee-venom Treatment on the monosodium iodoacetate(MIA)- induced osteoarthritis in rats. Arthritis was induced by injection of MIA(0.5 mg) into knee joints of rats. Arthritic rats were divided into control(n=8) and treated(n=8) group. Control group was injected with normal saline once a day for 20 days, while treated group was injected with Bee-venom extract once a day for same duration. Body weights were measured at 0, 5, 10, 15, 20 days after injection. At the end of experiment, gross and histopathological examination on the articular cartilages of the knee joints were performed. Proteoglycan contents of articular cartilages were analysed by safranine O staining method. The contents of $TNF-{\alpha}$, $IL-1{\beta}$ and IL-6 in synovial fluids were analysed by ELISA method. And also, COX-2 and iNOS immunohistochemical examination on the knee joints were performed. Body weights of the treated group were increased compared with control group at 20 days after injection. Grossly, the severity of osteoarthritis in the treated group were alleviated compared with control group. PG contents in articular cartilages of the treated group were significantly increased compared with control group. Histopathologically, degenerative and necrotic lesion of articular cartilages in the treated group were alleviated compared with those of the control group. $TNF-{\alpha}$ contents in synovial fluids of the treated group were decreased compared with control group. Positive reactions of COX-2 in chondrocytes and synovial membranes of the treated group were decreased compared with the control group. On the basis of these results, we concluded that Bee-venom treatment has anti-arthritic effects on the monosodium iodoacetate-induced osteoarthritis in rats. And it's effects were related with reduced secretion of $TNF-{\alpha}$ and COX-2 from osteoarthritic chondrocytes and synovial membranes.

  • Poststreptococcal glomerulonephritis (PSGN) is one of the most well-known and important infectious renal diseases resulting from a prior infection with group A ${\beta}$-hemolytic streptococcus. The typical clinical characteristics of the disease reflect acute onset with gross hematuria, edema, hypertension and moderate proteinuria after the antecedent streptococcal infection. In children, usually PSGN is healed spontaneously but if it combines with fast progressing glomerulonephritis, it would be developed to chronic renal failure. Therefore, it is important to make a fast diagnosis and treatment by simple tools to predict the course and the prognosis of disease. Sonography is a simple tool for diagnosis but there is no typical renal sonographic finding in PSGN, so it is difficult to predict the course and the prognosis of disease by sonographic findings. In comparison between two cases of renal sonographic findings in PSGN, a patient who showed more increased echogenicity in more extended area of renal sonography had the severe results of renal pathology, prolonged treatment period and low serum C3 level. Here, we report the different findings of renal sonography and pathology depending on the degree of severity between two patients. Thus, it is necessary to gather more information from further studies to make a consensus about the relationship between the renal sonography and the prognosis of disease in PSGN.
