Objectives : Recently, herbal acupuncture has been developed in the Korea since the earlier 1960' applied to various diseases including the cerebrovascular accident. The main characteristics of herbal acupuncture are a combination the merit of acupuncture and herbal medicine. It was not well known the therapeutic effect and the mechanism of herbal acupuncture on transient forebrain ischemic injury, although it has been used frequently in clinics. Ramulus Uncariae Cum Uncis (釣鉤藤) has been claimed to possess sedative, anti-spasmodic actions, and treat childhood epilepsy in oriental medical preparation. Also, it has been stated that Ramulus Uncariae Cum Uncis was antioxidatvie effect and neuroprotection against glutamateinduced neuronal death. Methods : In this study, effects of Ramulus Uncariae Cum Uncis' herbal acupuncture on the $GV_{20}{\;}or{\;}LR_3$, named Baek-hue or Tae-chung, on neuroprotection after the transient forebrain ischemia were investigated in Sprague-Dawely rats. Expressions of cFos, FosB and BDNF protein in the hippocampus and cortex were observed at 2 hrs and 48 hrs after transient forebrain ischemia by immunohistochemistry and ELISA technique. Results : Expression of cFos protein was increased slightly in the hippocampus and cortex at 2 hrs after transient forebrain ischemia, but FosB protein was increased highly comparing to cFos protein. However, pretreatment with Ramulus Uncariae Cum Uncis' herbal acupuncture on $GV_{20}{\;}or{\;}LR_3$ significantly increased expression of cFos protein and significantly decreased expression of FosB protein compared to control group, respectively. These features were observed in the motor cortex and retrosplenial granular cortex as well as the hippocampus. Especially, cFos expression was more increased at the herbal acupuncture on $GV_{20}{\;}than{\;}LR_3$, but FosB expression was more decreased in $LR_3$ group than $GV_{20}$ group. Also, pretreatment with Ramulus Uncariae Cum Uncis' herbal acupuncture on $GV_{20}{\;}or{\;}LR_3$ significantly increased the expression of BDNF protein in the hippocampus ($254.88{\pm}12{\;}pg/ml{\;}in{\;}GV_{20}$ group, $245.93{\pm}44.4{\;}pg/ml{\;}in{\;}LR_3$ group) and the cortex ($85.81{\pm}3.45{\;}pg/ml{\;}in{\;}GV_{20}$ group, $111.51{\pm}15.79{\;}pg/ml{\;}in{\;}LR_3$, group) compared to the hippocampus ($134.07{\pm}2.96{\;}pg/ml$) and the cortex ($61.16{\pm}4.11{\;}pg/ml$) in control group at 48 hrs after transient forebrain ischemia. Conclusion : These results suggest that pretreatment with Ramulus Uncariae Cum Uncis' herbal acupuncture on $GV_{20}{\;}or{\;}LR_3$ has neuroprotective effect on transient forebrain ischemia and the herbal acupunture on $GV_{20}{\;}or{\;}LR_3$ may be related to antioxidative effect and calcium channel block of Ramulus Uncariae Cum Uncis. Also, it could be mentioned there is specificity of acupoints treating ischemic injury through the difference between the herbal acupuncture of $GV_{20}{\;}and{\;}LR_3$.

In this paper, the effect of Ganopoly(extracts of Ganoderma lucidum) and Ganopoly/C+(70% Ganopoly + 30% chitosan) on cisplastin-induced nephrotoxicity was investigated in Sprague-Dawley rats. A single dose of cisplastin(5 ㎎/㎏) kg) was administered intraperitoneally after pretreatment of saline, Ganopoly and Ganopoly/C+ for 7 days. The nephrotoxicity and renal function were manifestated by the changes of body weight, blood pressure, biochemical changes and solute in urine and plasma. After the treatment of CDDP(cis-dichlorodiamineplatinum), a significant elevation of kidney weight, serum urea, cretinine, urine volume for 24 hours, urine magnesium, and a severe or significant decrease in body weight, blood pressure, creatinine clearance, urine osmolarity, serum albumin, etc. The nephrotoxicity was further confirmed by a significant decrease in glutathione S-transferase(GSH) in urine and kidney homogenate, GSH, glutathione peroxidase(GSH-Px) and catalase in kidney tissue. And also the lipid peroxidation was significantly increased in kidney homogenate. These signs of nephrotoxicity was ameliorated by the pretreatment and consecutive administration of Ganopoly and Ganopoly/C+ for 14 days after the Lp. injection of CDDP on 7th day after pretreatment of Ganopoly and Ganopoly/C+. The amelioration of nephrotoxicity was evidenced by significant reduction in serum urea and creatinine concentration, and improvement of other index of renal function. And The activity of antioxidant enzymes were partially recovered in kidney tissue of rats treated by CDDP and the administration of Ganopoly and Ganopoly/C+. These results indicate the cispastin induced nephrotoxicity is due to an impairment of tubular reabsorption systems enhanced by necrosis of proximal tubule, and the Ganopoly and Ganopoly/C+ has a partial protective effect on nephrotoxicity induced by CDDP. The polysacchride of Ganoderma lucidum may improve the therapeutic index of nephrotoxicity induced by CDDP. However, it is needed to elucidate the mechanism for confirming the therapeutic effect.

Scutellaria baicalensis Georgi. (SBGE) is known to be antioxidant effect. In addition of the effects, we further investigated the SBGE on the antioxidant effect on a renal cortical slices cell and kidney protecting effects. The results were as follows. 1 When renal cortical slices separated from a rabbit's kidney were treated with 1mM tert-Butylhydroperoxide (t-BHP) in the presence of SBGE. SBGE significant prevented t-BHP induced increase in lactate dehydrogenase (LDH) release and lipid peroxidation. 2. When renal cortical slices separated from a rabbit's kidney were treated with oxidant $300{\mu}M$ cisplatin in the presence of SBGE. SBGE significant prevented cisplatin-induced increase in LDH release and lipid peroxidation. 3. Pretreatment with 0.1g/kg SBGE for seven day and treatment with 5 mg/kg cisplatin by the intraperitoneal injection The results were that the pretreatment group with SBGE showed a significant decrease in lipid peroxidation, increase in clearance rate of blood urea nitrogen (BUN) and creatinine in the kidney than the administering single agent group of cisplatin. and pretreatment group with SBGE showed intact microvillus of proximal tubule and no contraction of rumen, it was a similar result with normal group. With the results SBGE showed to be highly effective on antioxidant effect and cellular protection activity against cisplatin that was a toxic agent on a kidney. Therefore, SBGE is considered to have protective effective on a disordered kidney or kidney diseases such as nephritis or renal failure that cause tissue damages in a kidney.

In this study, thermalpretreatment was used to solubilize organic matter contained in sewage sludge before acid fermentation. By thermal pretreatment, solubilization of particulate CODcr, carbohydrate and protein increased. By thermal treatment at $120^{\circ}C$ for 30 minutes, CODcr solubilization efficiency of the primary sludge reached 8.3%. Meanwhile, for the secondary sludge, CODcr solubilization efficiency reached 16.5% because of high solubilization ratio of protein under the same pretreatment conditon. The results of anaerobic biodegradability test showed that both VFAs conversion ratio and hydrolysis rate of organic compounds in sewage sludge were improved by thermal pretreatment. Meanwhile, the optimum thermal pretreatment condition was varied with composition of organic compounds in sludge. In this study, the optimun thermal pretreatment condition of the primary sludge, containing high concentration of carbohydrate, was $80^{\circ}C$ for 30 minutes. Meanwhile, for the secondary sludge, mainly composed of protein, the sludge treated at $120^{\circ}C$ for 30 minutes showed the effective organic removal and VFAs production.
It has been reported that the glycoprotein extracted from Aloe has strong anti-inflammatory response. However, there has been no research report yet about the effect of Aloe on allergic hypersensitivity reactivity. By using guinea pig lung mast cells, this study aimed to examine the effects of Aloe glycoprotein (NY945) on the mediator releases caused by mast cell activation, and also aimed to assess the effects of NY945 on the mechanism of mediator releases in the mast cell activation. We partially purified mast cell from guinea pig lung tissues by using the enzyme digestion, the rough and the discontinuous density percoll gradient method. Mast cells were sensitized with IgG1 (anti-OA) and challenged with ovalbumin. Histamine was assayed by fluorometric analyzer, leukotrienes by radioimmunoassay. The phospholipase D activity was assessed by the production of labeled phosphatidylalcohol. The amount of mass 1, 2-diacylglycerol (DAG) was measured by the $[^3H]DAG$ produced when prelabeled with $[^3H]myristic$ acid. The phospholipid methylation was assessed by measuring the incorporation of the $[^3H]methyl$ moiety into phospholipids of cellular membranes. Pretreatment of NY945 (10 ${\mu}g$) significantly decreased histamine and leukotrienes releases during mast cell activation. The decrease of histamine release was stronger than that of leukotriene during mast cell activation. The phospholipase D activity increased by the mast cell activation was decreased by the dose-dependent manner in the pretreatment of NY945. The amount of DAG produced by PLC activity was decreased by NY945 pretreatment. The amount of mass 1, 2-diacylglycerol produced by activation of mast cells was decreased in the pretreatment of NY945. NY945 pretreatment strongly inhibited the incorporation of the $[^3H]methyl$ moiety into phospholipids. The data suggest that NY945 purified from Aloe inhibits in part an increase of 1, 2-diacylglycerol which is produced by activating mast cells with antigen-antibody reactions, which is mediated via phosphatidylcholine-phospholipase D and phosphatidylinositol-phospholipase C systems, and then followed by the inhibition of histamine release. Furthermore, NY945 reduces the production of phosphatidylcholine by inhibiting the methyltransferase I and II, which decreases the conversion of phosphatidylcholine into arachidonic acid and inhibits the production of leukotrienes.

We have investigated pretreatment of waste wood using milling refinery combined with poping method, which can save energy for pretreatment and enzyme loading for enzymatic hydrolysis. The chemical analysis of holocellulose of non and popping treated waste wood showed 65.9% and 58.8%, and the lignin, organic extracts and ash were increased by 3%, 4% and 0.7% after pretreatment, respectively. The reducing sugar yields of pretreated waste wood were increased four times more than non-pretreated one and the synergistic effect of cellulase and xylanase were evaluated compare with individual enzyme treatment. Especially, enzyme cocktail (cellulase 50 U and xylanase 50 U) treatment was very efficient in 1% substrate (50 mg). Also, glucose and xylose conversion rate of pretreated waste wood by GC analysis were 45.9% and 38.7%, respectively.
Objectives : In this study, the anti-stress effects of ethanolic extract of Opuntiaficus-indica (OF70E) were investigated. Methods : To determine the effects of OF70E on physical stress, changes in whole-body cortisol level or behavior were monitored in zebrafish. After treatment with 0.9% saline or OF70E for 6 min, all fish underwent net handling stress (NHS), which induced physical stress. And then, we conducted open field test (OFT) or sacrificed fish for collecting body fluid from whole-body. We used the cortisol enzyme-linked immunoassay kit to measure the amount of cortisol in each zebrafish sample. Results : In result, compared with normal group which were not treated by NHS, whole-body cortisol levels were significantly increased in stressed-control group. Compared with control group, pretreatment with OF70E at concentrations of 25, 50 and 100 mg/L for 6min significantly inhibited the increase of whole-body cortisol levels induced by NHS(p<0.05). To anti-stress effects of OF70E on behavior, we conducted OFT after the induction of NHS following pretreatment of OF70E. As results of OFT, compared with unstressed-normal group, distance moved was significantly decreased by induction of NHS in stressed-control group (p<0.05). OF70E-pretreatment blocked decreases of distance moved increased by NHS (p<0.05). And meandering movement, immobility and turn angle were significantly increased by NHS in stressed-control group compared with unstressed-normal group (p<0.05). OF70E-pretreatment prevented the increases of meandering movement immobility and turn angle by NHS (p<0.05). Conclusions : In conclusion these results suggest that OF70E-pretreatment may prevent stress responses.

Freezing pretreatment can destroy the cell membrane of garlic and may improve some food-quality of garlic. Therefore we investigated the effect of freezing pretreatment at $-20^{\circ}C$ and $-70^{\circ}C$ on quality of aged black garlic, compared with traditional processing methods. Our results showed that freezing pretreatment at $-70^{\circ}C$ had the greatest impact on qualities and antioxidant activities of black garlic. Browning degree and pH of black garlic after both the freezing pretreatment and aging process were 3.14 and 3.55, respectively. Furthermore, 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activity and reducing power of aged black garlic can be enhanced by pre-freezing processing. Reducing sugar and 5-hydroxymethyl-2-furaldehyde (5-HMF) contents of freezing pretreated and aged black garlic were increased by 1.69 and 1.14 fold, respectively, compared with the control samples. The results indicated that freezing pretreatment had improved the overall qualities (such as browning degree, pH, reducing sugar) and functional materials of black garlic.
To investigate the detoxificative effect of tea, five kinds of tea(mulberry, anaerobic treated mulberry, green, barly tea and corm tea) were selected and determined their dotoxication activities for Cd and Pb in drinking water. The effect of tea on the removal of Cd and Pb were increased proportionally to the contents of teas. Anaerobic treated mulberry leaf tea showed stronger detoxication activity than the others. In drinking water contaminated with Cd, the removal effect of Cd was high 27% by anaerobic treated mulberry leaf tea and 14% by mulberry leaf tea as compared to green tea. Also, in drinking water with Pb, the removal effect of anaerobic treated mulberry leaf tea was the best among five kinds of tea. Pretreatment method on the removal effect of Cd was better than post-treatment method in the treatment method.
The present study examined the effect of a methanol extract of Evodiae Fructus on the blood pressure in spontaneously hypertensive rats (SHR). The systolic blood pressure was measured after rats were pretreated with phentolamine, propranolol, or $N_{\omega}$-nitro-$_{L}$-arginine methyl ester(NAME) and subsequently received methanol extract of Evodiae Fructus. In SHR, intraperitoneal administration of methanol extract of Evodiae Fructus (0.5 mg/kg) produced antihypertensive effect that lasted for at least 4 hours. Antihypertensive effect of Evodiae Fructus was more stronger than that with $\alpha$-adrenergic receptor antagonist phentolamine and was not affected by $\beta$-adrenergic receptor antagonist propranolol. The antihypertensive effect of Evodiae Fructus was abolished by pretreatment of NAME. Our findings suggest Evodiae Fructus has an hypertensive effect, which may be mediated through nitric oxide synthesis.s.
