이기상,안윤수,이경수,하호성,Lee, Ki-Sang,Ahn, Yoon-Soo,Rhee, Gyeong-Soo,Ha, Ho-Sung 한국토양비료학회 1986 한국토양비료학회지 Vol.19 No.4
유효규산함량이 61 ppm 사양토(砂壤土)에서 규회석(硅灰石) 및 규산질비료시용(珪酸質肥料施用)에 의한 규산용출(珪酸溶出)의 변화(變化)에 관(關)해서 실내(室內) 시험(試驗)을 수행(遂行)한 결과(結果)를 요약(要約)하면 다음과 같다. 1. 규회석(硅灰石) 및 규산질비료(珪酸質肥料)를 토양(土壤)에 처리(處理)하고 증류수(蒸溜水) 및 1N-NaOAc(pH 4.0)로 연속침출(連續浸出)했을 때 각(各) 침출용액중(浸出溶液中)의 규산용출농도(珪酸溶出濃度)는 규회석(硅灰石)보다 규산질비료(珪酸質肥料) 처리(處理)에서 높았다. 2. 규회석(硅灰石) 및 규산질비료(珪酸質肥料)를 토양(土壤)에 처리(處理)하고 증류수(蒸溜水)로 연속침출(連續浸出)했을 때 pH는 규산질비료(珪酸質肥料)보다 규회석처리(硅灰石處理)에서 높았다. 3. 규회석(硅灰石) 및 규산질비료(珪酸質肥料)를 토양(土壤)에 처리(處理)하고 항온(恒溫)했을 때 규회석처리(硅灰石處理)는 시용량(施用量)이 많아짐에 따라 수용액중(水溶液中)의 $SiO_2$ 및 K 농도(濃度)는 낮아졌고 규산질비료(珪酸質肥料)에서는 높아졌으며 pH, Ca 및 Mg 농도(濃度)은 두비종(肥種) 모두 높아졌다. 4. 토양(土壤)에 pH를 달리하여 규산용액(珪酸溶液)을 흡착(吸着)시킨 결과(結果) pH 9.4 정도(程度)에서 최대(最大)로 흡착(吸着)되었다. A laboratory experiment was conducted to investigate silica solubility in soil with specific reference to the characteristics of iron refinery slag and wollastonite. The results are as follows; 1. The slilia concentrations successively extracted by distilled water and N-NaOAc (pH 4.0) in soil treated with the two silicate fertilizers, is higher in iron refinery slag than in wollastonite, while the pH values of soil-fertilizer suspensions successively extracted by distilled water were the opposite. 2. Silica concentrations due to increasing of fertilizer application were decreased in iron refinery slag-soil suspensions but the concentrations were increased in wollastonite-soil suspensions. 3. The amounts of silica adsorbed in different pH of soil suspension were maximized under the condition maintained pH of near to 9.4.

The Present experiment was designed to investigate the effects of Soo Jeom San on the function of heart and digestive organs. And thus it was analyzed the total acidity, recovery effect, and the other various enzyme activities such as ATPase, Creatine kinase, Aspartate transaminase, and Lactate dehydrogenase. The results were obtained as follows : 1. The Total acidity decreased after Soo JeomSan administration for 6 days, however the total acidity inoreased after the drug administration for 9 days, these phenomena demonstrate that Soo Jeom San acts as a dual factor. The mechanism of decreasing the total acidity was considered to the inhibition of ATPase activity used for HCI active transport from parietal cells. 2. Soo Jeom San recovered the islets of Langerhans which was disrupted by streptozotocin. The recovery mechanism was suggested that Soo Jeom San stimulates the ${\beta}-cell$ proliferation. 3. Soo Jeom San inhibited the enzyme activities such as Creatine kinase and Aspartate transaminase, however the drug activated Lactate dehydrogenase. According to the obtained results, Soo Jeom San may be used for curing gastric ulcer and myocardiac infarction.
