Lamotrigine is an antiepileptic drug widely used to treat epileptic seizures. Using whole-cell voltage clamp recordings in combination with a fast drug application approach, we investigated the effects of lamotrigine on 5-hydroxytryptamine $(5-HT)_3$ receptors in NCB-20 neuroblastoma cells. Co-application of lamotrigine ($1{\sim}300{\mu}M$) resulted in a concentration-dependent reduction in peak amplitude of currents induced by $3{\mu}m$ of 5-HT for an $IC_{50}$ value of $28.2{\pm}3.6{\mu}M$ with a Hill coefficient of $1.2{\pm}0.1$. These peak amplitude decreases were accompanied by the rise slope reduction. In addition, $5-HT_3$-mediated currents evoked by 1 mM dopamine, a partial $5-HT_3$ receptor agonist, were inhibited by lamotrigine co-application. The $EC_{50}$ of 5-HT for $5-HT_3$ receptor currents were shifted to the right by co-application of lamotrigine without a significant change of maximal effect. Currents activated by 5-HT and lamotrigine co-application in the presence of 1 min pretreatment of lamotrigine were similar to those activated by 5-HT and lamotrigine co-application alone. Moreover, subsequent application of lamotrigine in the presence of 5-HT and 5-hydroxyindole, known to attenuate $5-HT_3$ receptor desensitization, inhibited $5-HT_3$ receptor currents in a concentration-dependent manner. The deactivation of $5-HT_3$ receptor was delayed by washing with an external solution containing lamotrigine. Lamotrigine accelerated the desensitization process of $5-HT_3$ receptors. There was no voltage-dependency in the inhibitory effects of lamotrigine on the $5-HT_3$ receptor currents. These results indicate that lamotrigine inhibits $5-HT_3$-activated currents in a competitive manner by binding to the open state of the channels and blocking channel activation or accelerating receptor desensitization.

To elucidate the optimum fertilizer level and application method for band application under puddled-soil drill seeding in Jeonbuk series of fluvio-marine alluvial soil at National Honam Agricultural Experiment Station in 1995, using Dongjinbyeo, slow releasing compound fertilizer of 100％ and 80％ to conventional application level was applied totally as basal fertilizer simultaneously with seeding under 3cm and 5cm depth from soil surface in a distance of 4cm from the seeded row. Plant height was taller and tiller number was higher in band application than conventional application but ratio of effective tiller was vice versa. Panicle number was more but ratio of effective tiller ratio was lower in 100％ than 80％ level of band application and they were higher in 3cm than 5cm depth from soil surface. Leaf area index and dry weight was higher in conventional application at early growth stage but was vice versa after maximum tillering stage, and they were higher in 3cm depth at early growth stage but 5cm depth after maximum tillering stage. NH$_4$-N in soil was higher in conventional application at 25 days after seeding but, thereafter was lower than band application and it was higher in 3cm than 5cm depth till 40 days after seeding but was versa, thereafter. Lodging degree was slightly higher in band application, 100％ level and 5cm depth than in their counterparts. Panicle number and grain number per $m^2$ was lower in conventional application than 80％ or 100％ level of band application without significant difference between band application levels or application methods. Yield was higher at 80％ level of band application under 3cm depth than conventional application, but no significantly different among other application methods. Therefore, 80％ level of band application under 3cm depth of soil surface was more effective for puddled-soil drill seeding on the basis of the reduction of application efforts, better plant growth and higher yield in rice.

This experiment was conducted to determine the economic application method of Yakto among 6 application method : amount of Yakto application $3\;plot(70\;l,\;25.5\;l,\;13,3\;l/kan;\;180cm{\times}90cm),$ and added side dressing(3 l/kan) each plot. The reduced amoumt of Yakto application(25.5 l, 13.3 l/kan) were lower the contents of inorganic nitrogen, $P_{2}O_{5},\;K,\;Ca$ and Mg, but similar pH in bed soil compared with standard Yakto application(70 l/kan). Side dressing applicated on 29 May increased the contents of inorganic nitrogen, $P_{2}O_{5},\;K,\;Ca,\;Mg$ and salt concentration in bed soil compared with non­side dressing in each Yakto application plot(70 l, 25.5 l, 13,3 l/kan). The reduced amoumt of Yakto application(25.5 l/kan) added side dressing(3 l/kan) were similar the contents of inorganic nitrogen, K, Mg and salt but lower $P_{2}O_{5}$ and Ca in bed soil compared with standard Yakto application(70 l/kan) in June. The reduced amoumt of Yakto application(25,5 l/Kan) added side dressing(3 l/kan) was similar the contents of P, K, Ca and Mg but lower N in leaves compared with standard Yakto application(70 l/kan). The reduced amoumt of Yakto application(25.5 l/kan) added side dressing(3 l/kan) was shorter stem length, and higher $5{\%}$ chlorosis of leaf tip, but similar emergence ratio, survival ratio, leaf senescence ratio, chlorophyll, stem diameter and leaf area compared with standard Yakto application(70 l/kan). These suggested that 25.5 l Yakto application added side dressing(3 l/kan) per kan might be possible economical application method of Yakto.

This study was carried out to determine the effect of continuous application of animal liquid slurry on the growth and yield of rice in 2005. Field experiment was conducted under variable continuous application years of animal liquid slurry; 1, 3, 5 application years of slurry and chemical fertilizer as control plot. The effects of different application years of slurry on the growth characteristics and yield of rice were determined. The plant height and tiller's number of 1 year application of liquid slurry were lower than those of the chemical fertilizer plot. But in the plot of 5 years continuous application of animal slurry, the height and tillers of rice were higher than those of 1 year application. And the color of leaf 5 years application years plot was darker than that of the chemical fertilizer. Yield of the 5 years continuous application of slurry was 4% higher than that chemical fertilizer, but that of 1 year application was decreased 6% compared with chemical fertilizer. The long time application of animal slurry was increased content of organic matter, $P_2O_5$ and exchangeable caution(K) in soil.

This experiment was conducted to determine economic application method of Yakto among 6 application method : amount of Yakto application 3 plots(70 l, 25.5 l, 13.3l/kan), and added side dressing(3 l/kan) each plot. The reduced Yakto application(25.5 l/kan) with side dressing(3 l/kan) showed similar root diameter, fresh weight of roots and yield of good seedlings to standard Yakto application(70 l/kan). And also this application method of Yakto gave similar content of Ca and Mg, but the lower content of N, P, K in roots to standard Yakto application(70 l/kan). These suggested that 25.5 l Yakto application added side dressing(3 l/kan) per kan might be economical application method of Yakto.

Silage wm(cv, Gwanganok) was cultivated during 1991-1994 on paddy land as a rotational cropping system of rice, to evaluate the effect of cattle manure application on the soil characteristics, yield performance and quality of com plant. The treatments used in this study were non-fertilizer, NPK standard in chemical fertilizer(N:$P_2O_5$ : $K_2O$= 200 : 150 : 150 kg/ha), cattle manure 20.40, 60 and 80 ton/ha Application of cattle manure improved soil pH, organic matter, available phosphate and exchangeable cations in the soils. During the experiment, soil pH was improved from 4.7 in the chemical fertilizer application(control) to 5.4-5.6 in the application of cattle manure, and available $P_2O_5$ wntent was increased from 72.2 ppm(contro1) to 340.2 ppm(cattle manure 80 ton/ha). Application of cattle manure increased plant growth, plant height and stalk diameter, and silage yields. Dry matter yields were produced 15.88 ton(chemical fertilizer), 20.11 ton(cattle manure 40 ton) and 21.22 ton/ha(cattle manure 80 ton/ha). However, no signicant yield differences were observed between cattle manure 40, 60 and 80 tonlha Productions of total digestible nutrients(TDN) and net energy for lactation(NEL) were also increased under cattle manure application. From the abobe results, the proper application amount of cattle manure was 40 tonha in this experiment.

This study was carried out to clarify the effect of silicate application on rice grain quality and storage characteristics in Ilpumbyeo cultivar. In yield and yield components, panicles and spikelet numbers were increased and ripened grain rate was also increased by 2%. Head rice yield was increased by $7.7{\sim}9.5%$ in silicate application. Protein content of milled rice was reduced by $0.2{\sim}0.3%$ and head rice rate was increased by $2.9{\sim}6.7%$ in silicate application due to decrease of chalky and damaged rice rate. In milling characteristics, color separation rate was improved by $4.2{\sim}7.2%$ and colored rice rate was decreased by $5.5{\sim}16.6%$ in silicate application. Acid value of stored brown rice were increased slowly in low temperature and silicate application, but that in room temperature and no silicate application was increased remarkably. The best degree rate of stored brown rice (over than 7.5 of pH) measured by the pH of grain was increased by the silicate application in both low and room temperature. Therefore, it was suggested that the storage characteristics of rice grain was improved by the silicate application.
