  • The water extract of Gamidaebo-Tang depressed the lethal toxicity of cis-platin$(45{\mu}M/kg,\;s.c.)$, and mitomycin C (6mg/kg, s.c.). Significant depression of renal toxicity(indicated by an increased blood urea nitrogen value and creatinine value) of cis-platin $(35{\mu}M/kg)\;s.c.)$, was observed in mice treated with Gamidaebo-Tang. In rats treated with mitomycin C and Gamidaebo-Tang, the increased LDH activity and reduced total protein and albumin contents by mitomycin C were significantly depressed. The number of WBC was significantly increased in rats treated with mitomycin C but in the rats treated with mitomycin C and Gamidaebo-Tang, the number of WBC was increased and the hematocrit value and the number of RBC and Hgb were significantly increased in the dose-dependent manner. Therefore, bone marrow toxicity of mitomycin C in the rats treated with Gamidaebo-Tang was depressed. In the end, alleviative effects of the side actions of cis-platin and mitomycin C were acknowledged by combined usage of Gamidaebo-Tang and these anti-neoplastic drugs.

  • This experiment was conducted to investigate the effects of water depths on seedling stand and early growth of califonia rice varieties, S201, M202, A301, Italico livorno and Korean variety, Hwaseongbyeo, and barnyardgrass (Echinochloa crus-galli) The coleoptile length of rice was longer with deep water depth while for the radicle length shorten. As water depth was increased, the percentage of seedling stand were decreased slightly in rice, while sharply increased in barnyardgrass. Plant height of rice with increasing water depth were longer, whereas that of barnyardgrass reduced significantly with weaker. Tiller number of rice and barnyardgrass were significantly reduced as water depth increased. Dry matter weight and healthy score of rice seedling at 35DAS were highest in 7.5cm water depth followed saturated moisture, 15, and 22.5cm water depth, while for barnyardgrass those were especially negatively affected by deep water depth. These results showed that the seedling stand and early growth of barnyardgrass was highly suppressed by deeper water levels compared with rice. Rice cultivars which are showes growth characteristics in deeper water levels at early growth stage were Italico livorno and S201 in Japonica / Indica.

  • Although Semisulcospira libertina is generally regarded as a supplement for the alleviation of alcohol hangover, little is known about its effects on cell metabolism. Therefore, this study was conducted to analyze the constituents of the extracts prepared using different extraction methods and to compare their biochemical properties. The amino acid contents were found to be much higher in acidic and enzymatic hydrolysates than hot water extracts from S. libertina. DPPH radical scavenging activities in acidic and enzymatic hydrolysates were higher than those of hot water extracts. Three types of S. libertina hydrolysate was added to HepG2 cells damaged by acetaminophen (AAP), after which the survival rate of HepG2 cell were measured. In addition, lactate dehydrogenase (LDH) activities in the culture media were evaluated. The survival rates of HepG2 cells were $77.0{\pm}4.3%$ and $81.5{\pm}1.3%$ at 3 h and 5h enzymatic hydrolysates, respectively. These cell survival rates were higher compared to those of the negative control group ($67.8{\pm}4.3%$) treated only with acetaminophen. Cellular toxicities induced by treatment with AAP were also significantly alleviated in response to treatment with the extracts of S. libertina. In addition, the activities of 2 key enzymes that metabolize ethanol, alcohol dehydrogenase and aldehyde dehydrogenase, were upregulated by 4.7- and 2.7-fold respectively in response to treatment with a 3 h enzymatic hydrolysate of S. libertina. Taken together, these results provide biochemical evidence of the method by which S. libertina exerts its biological functions, including the alleviation of alcohol hangover and the protection of liver cells against toxic insults.

  • Cyclosporine(CsA) is an immunosupressant drug widely used in post-allogeneic organ transplant to reduce the activity of the patient's immune system and so the risk of organ rejection. It has been studied in transplants of skin, heart, kidney, liver, lung, pancreas, bone marrow and small intestine. Initially isolated from a Norwegian soil sample, Both kidney and liver dysfunction are prominent side effects of CsA. The present study was designed to determine the possible protective effect of salidroside(Sal) isolated from the BuOH extract of Acer termentosum Max against oxidative damage in CsA-treated(50 mg/kg, ip) nephrotoxicity rats. Results showed oral administration of methanol and butanol extact of Acer termentosum Max(200 mg/kg, po) significantly reduced activities of marker enzymes(BUN, Creatinine) and LDH activity in serum to CsA induced experimental kidney injured rats. And significantly decrcease of protein amount level in urine and activities of free radical formation enzyme were significantly improved by the treatment of Sal. And significantly decrcease of MDA level in kidney and activities of calalase, glutathione peroxidation and SOD were significantly improved by the treatment of Sal(20 mg/kg, po). But glutathione concentration and glutathione S-transferase actitity was not affected. Results of this study revealed that Sal could afford a significant protection in the alleviation of CsA-induced nephrotoxicity injury.

  • The aim of this study was to provide basic haematological information to allow improved nutritional management for velvet production in spotted deer (Cervus nippon) by investigating biochemical changes in blood values during the antler growth period. Blood samples, obtained from the jugular vein of twenty-five deer, were taken every 10 days from casting (day 0) to harvesting (day 50) of velvet antler. Negligible changes were found in the concentrations of total protein, albumin, and creatinine during the antler growth period, but there were significant changes in the concentrations of urea (p<0.05) and uric acid (p<0.01). The concentration of triglyceride was significantly higher (p<0.05) during the antler growth period compared to casting time, while serum high-density lipoprotein concentrations were low and remained unchanged during the antler growth period. Serum glucose concentration increased (p<0.05) significantly and was slightly changeable during antler growth. The serum concentrations of Ca and P did not fluctuate during antler growth, while those of Na, K and Cl showed slight differences between the time of casting and the rest of the antler growth period. No significant changes in concentrations of AST, ALT, amylase, CK, GGT and LDH were detected during the antler growth period. However, the concentration of ALK-P increased during antler growth reaching its peak on day 50 after casting. We found a significant difference in the concentration of ALK-P between the time of casting and the rest of the antler growth period (p<0.01). Consequently, antler growth was associated with mild changes in measured serum biochemical values with the exception of ALK-P activity in spotted deer.

  • $Amyloid-{\beta}$ protein ($A{\beta}$) is known to increase free radical production in neuronal cells, leading to cell death by oxidative stress. The purpose of this study was to evaluate the protective effects of $PineXol^{(R)}$ on $A{\beta}_{25-35}$ induced neuronal cell death. Rat pheochromocytoma (PC-12) cells were pre-treated with $100{\mu}g/mL$ of $PineXol^{(R)}$ for 2 h. The cells were exposed to single dose of $30{\mu}M$ $A{\beta}_{25-35}$ for 24 h. Cell death was assessed by a cell count kit-8 (CCK-8) assay, lactate and dehydrogenase (LDH) release assay. An Apoptotic process was analyzed by a protein expression of the Bcl-2 family using western blotting. Cell viability increased in PC-12 cells treated with both $A{\beta}_{25-35}$ and $PineXol^{(R)}$, compared to the control group. $PineXol^{(R)}$ induced a decrease of the Bcl-2 protein expression (p<0.05), while Bax and Sod1 increased (p<0.05), indicating attenuation of $A{\beta}_{25-35}$ induced apoptosis. These results suggest that $PineXol^{(R)}$ may be a good candidate for the prevention of Alzheimer's disease(AD).

  • Objective : Recent studies indicate that the deposition of ${\beta}-amyloid$ ($A{\beta}$) is related in the pathogenesis of Alzheimer's disease (AD), but the underlying mechanism is still not clear. Method : To investigate the potential cellular functions of APP and water extract of the JangwonHwangagambang (JWHG), we use as in vitro model, neuro 2A cells were treated with either JWHG or its oriental medicines, and the effect in APP expression was determined by MTT and LDH assay. JWHG have been shown to be neuroprotective in different model systems. We asked whether JWHG treatment would influence cell survival and AD-like pathology in APP-induced neuronal cells. Result : JWHG and water extracts of some oriental medicine has attenuated high cell death in vitro. JWHG-treated cells increased percentage of cell survival more longly than controls. JWHG had significantly increas neurite outgrowth in the as compared to control cells. Conclusion : These results suggest that JWHG prevent APP-induced neurotoxicity through attenuating oxidative stress, and may be useful as potential therapeutic agents for AD.

  • Effects of repeated administration of diminazene aceturate (Hoechst Veterin r GmbH. Ger- many) that has been introduced as effective compound against Babesiosis and trppanosomiasis were investigated in dogs experimentally infacted with Babesia gibsoni. Adull mongrel dogs of both sexes were inoculated will nonpreserved infected blood and then maintained chronic anemia. A single dose of diminazene aceturate of 7mg/kg b.w. was administrated intramnuscularIy on day 7.1 arid ,7. Clin- ical and hcmatological findings following inoculation and medication were observed and 7enlm bio chemical analysis also was monitored. Parasitemia was detected between 3 and 6 days after inoculation. The rate of parasitized erythrocytes,1 in peripheral blood reached the peak on the 13th day and was maintained the percentage of 0.1 to 1.0 until the medication of diminazene aceturate. RBC was significantly (p<0.01) decreased on the 3rd day and then kept on decreasing. The lowest value was observed on the 16th day. WBC remained generally within normal ranges. PCV revea1ed the sig-nificant (p<0.01) decrease within the range of 24-27% and platelet was significantly (p<0.05) decreased during the period. Senum chemical values (ALT, AST. total bilirubin. LDH BUN, area- tinine, total protein. albumin and glucose) were within normal ranges during the experimental period. Serum CPK values were significantly (p<0.01) increased on the 3rd day. There was no clinically, sig-nificant difference in a single dose of diminazene aceturate of 7 mg/kg b.w. But the administration of diminazene aceturate of 14 mg/kg b.w. revealed vomiting and anorexia and one dog died in 30 hours after administration. The administration of 14mg/kg b.w. resulted in vomiting, salivation, actor- exia, tremor of head and involuntary movement and one dog died in 27 hours after administration. WBC, RBC, PCV and Platelet values were no significant difference and hematological findings revealed persistent anemia and thrombocytopenia during chronic anemia after inoculation. AST activity its was significantly (p<0.01) increased 11\\`from 3 days after medication and AST activity was on the same trend. Serum CPK activity revealed significant (p<0.01) increase within 6 hors)\\`s after every administration and decreased in 48 howl·s after administration.
