Effect of single administration of Polygala tenuipolia was examined on short-term memory in step through test and the intensity of the immunoreactive c-Fos protein induced by oral administration of ethanol. The acquisition of memory was significantly reduced by ethanol, and ethanol amnesia was remarkably reversed following oral administration of Polygala tenuifolia. c-Fos protein in normal rat brain was highly expressed in order of thalamus, pariental cortex, hippocampus, hypothalamus, amygdaloid and cingulate cortex. The expression of Fos protein was remarkably suppressed by single administration of ethanol. The inhibitory effect of ethanol on expression of Fos protein was reversed by single administration of Polygara tenuipolia, especially tissues of limbic areas such as amygdala, parietal cortex and CA3 of hippocampus. These results suggested that the amelioration process of Polygala tenuipolia on ethanol amnesia seems to be involve the expression of c-Fos protein in partly.

A nondispersive infrared (NDIR) ethanol gas sensor was prototyped with ASIC implemented thermopile sensor, which included a temperature sensor and two ellipsoidal waveguide structures. The temperature dependency of the two ethanol sensors (with partially blocked and intact structures) has been characterized. The two ethanol gas sensors showed linear output voltages initially when varying the ambient temperature from 253 K to 333 K. The slope of the temperature sensor presented a constant value of 15 mV/K. After temperature compensation, the ethanol gas sensor estimated ethanol concentrations with larger errors of 20 to 25% below 200 ppm. However, the estimation errors were reduced to between -10 and +1 % from 253 K to 333 K above 200 ppm ethanol gas concentration in this research.

The fermentative characteristics in ethanol production from lactose, with increased ethanol tolerance, of a fusant yeast strain constructed by protoplast fusion of Saccharomyces cerevisiae and Kluyveromyces fragilis were studied. The ethanol tolerance of this strain was increased to 8.0%, compared with the parent K. fragilis. During batch ethanol fermentation the optimal cultivation conditions for this fusant yeast were an initial pH of 4.5, a culture temperature $30^\circ{C}$. stirring at 100 rpm without aeration in 10% lactose medium (supplied with 1.0% yeast extract). Using this fusant strain in whey fermentation to ethanol, maximum ethanol production reached 3.41% (w/v) (theoretical yield; 66.7%) after a 48 hour cultivation period.

In order to select the optimum ethanol concentration for extraction of volatile components in cinnamon, the dried cinnamon was extracted with water and 30∼90% ethanol. The volatile components of cinnamon extracts were isolated by the simultaneous distillation extraction method using Likens and Nickerson's extraction apparatus, and analyzed by GC-MS. In cinnamon bark powder 45 components were detected and 21 components were identified. The major component of cinnamon bark powder was cinnamic aldehyde. In water extract of cinnamon, volatile components were not extracted sufficiently. The volatile components of cinnamon were increased with the increment of ethanol concentraction upto 70%. The volatile component of 70% ethanol extract showed similar pattern and amount to cinnamon bark powder. But in 90% ethanol extracts, the number and amount of volatile component were reduced. The above data suggested that 70% ethanol was the most effective solvent for volatile components extraction of cinnamon.

In the previous research about ethanol production, we confirmed that SFW(saccharified foodwastes) medium(0.56g-ethanol/g-glucose) is mere efficient than YM medium(0.538g-ethanol/g-glucose). Ethanol production using SFW needs large enzyme cost due to the enzymatic hydrolysis of foodwastes, although the enzymes was obtained from our economical enzyme production methods, using the intact whole culture broth of Trichoderma harzianum FJ1. Therefore, in this research we used synchronous saccharification and fermentationmethod to produce ethanol using foodwastes. Ethanol production yield was 0.45g-ethanol/g-reducing sugar in synchronous saccharification and for-mentation by a fed-batch mode.

The extracts fermented of rice germ are called GMT (Glumate) which is a main ingredient of Condition$^{\circledR}$. It has been reported that GMT reduced the blood concentrations of alcohol in heathy adults. The purpose of the study is to examine the effect of GMT on blood concentrations of ethanol and on heart rate increase induced by ethanol. GMT was administered orally to 15 healthy adults before (10 min) and after (1 h) ethanol ingestion. The oral administration of GMT before (10 min) and after (1 h) ethanol ingestion reduced the area under the blood concentration of ethanol-time curve (p<0.12) and tended to inhibit the ethanol-induced heart rate increase.

Objectives : To investigate the effect of Taxilli Ramulus (TR) extract on bone metabolism of ethanol-treated animal model. Methods : The changes of serum calcium, calcitonin, estrogen level, a1ka1ine phosphatase activity, osteocalcin, parathyroid hormone content and urine calcium level were observed with ethanol treatment for 60 days. The results were compared with an ethanol- TR extract double treatment group. Results : We observed increment of serum osteocalcin, parathyroid hormone content, alkaline phosphatase activity and urine calcium level by chronic ethanol feed and they were recovered to near normal level with Taxilli Ramulus extract treatment. Weight gain, serum calcium level, calcitonin and estrogen content were remarkably reduced with ethanol treatment and their levels were normalized by Taxilli Ramulus extract. Conclusions : These results showed that Taxilli Ramulus extract have the ability to recover to normal in the body an abnormal calcium metabolism process due to external factors. These results suggested that Taxilli Ramulus extract have preventive effects on calcium concentration loss and osteoporosis.

This study was designed in order to clarify the effect of ethanol drinking on the mineral contents on liver, kidney, muscle and hair. Forty-five rats were divided into 2 groups and a control group. The control group received tap water and the other 2 groups were given 8% and 40% ethanol as drinking source. Liver, kindney, muscle and hair samples were taken and analyzed for zinc, calcium and copper contents by atomic absorption spectrophotometric methods. The results obtained are summrized as follows; 1. The zinc content of muscle showed significant (p<0.01) decrease in both groups. 2. The calcium content of hair showed significant (p<0.1) increase in 8% ethanol group. 3. The copper contents of kidney and muscle in 8% ethanol group and liver in 40% ethanol group showed significant (p<0.1) decrease.

investigate action of ethanol on histamine release from rat peritoneal mast cells, we compared the inhibitory effect of ethanol with those of calcium antagonists in mechanism of between ATP and compound 48/80-induced histamine release. Ethanol dose-dependently inhibited 100 ${\mu}{\textrm}{m}$ ATP-induced histamine release, whereas did not inhibit 1 $\mu\textrm{g}$/ml compound 48/80-induced histamine release. Verapamil, TMB-8 and EGTA dose-dependently inhibited ATP-induced histamine release, but did not inhibit compound 48/80-induced histamine release. Such an inhibitory effect of calcium antagonist was similar to that of ethanol. These results suggest that the inhibitory effect of ethanol on histamine release from rat peritoneal mast cells is mediated via disturbance of calcium mobilization..

Ethanol treatment method was attempted for the selective isolation of ethanol-tolerant fungi from two sites of rice paddy fields around Seoul area. The vertical and seasonal fluctuation of the fungal population were also investigated. The ethanol-tolerant fungi were Talaromyces stipitatus, T. flavus var. flavus, T. helicus var. major, Eupenicillium javanicum, Emericellopsis terricolor, Pseudourotium zonatum, Aspergillus flavus, Cladosporium cladosporioides, Penicillium frequentans, P. janthinellum, and P. verruculosum. The most dominant species isolated by this method was T. stipitatus. It was found that the numbers of fungal species and colony forming units(CFUs) of ethanol-tolerant fungi were higher in Ascomycota than in Deuteromycota. A particular tendency appeared the highest CFUs in autumn, but lower in spring and winter. T. stipitatus was the dominant species of ethanol tolerant microfungi. This result would suggest that membrane lipid composition of ethanol-tolerant fungi isolated from the soils may play on important role in the ethanol tolerance.
