        小柴胡湯 煎湯液의 經時的 效能 變化에 關한 硏究

        韓官錫,崔永奉,李暎鍾 대한본초학회 1998 大韓本草學會誌 Vol.13 No.2

        In order to investigate the effective changes of Sosihotang prescription over a time, the decoction extracts of Sosihotang were adminstered to the TAA intoxicated rats. The obtained results were as follows : 1. Few changes were noticed in pH and Specific Gravity of decoction extracts. 2. In each activated change of GOT, GPT in the Serum, significant change appeared during the first 10 days, but from 13th day and on no significant value change appeared. 3. In each activated change of ALP and LDH in the Serum, significant change appeared during the first 10 days, but from 13th day and on no significant change in values appeared. From the above results, to maintain pharmacological effects, we recommend that the storage of Sosihotang decoction beyond 10 days should be avoided.

      • 리기다 소나무 및 측백나무 幼苗의 T/R率 調査

        韓關錫 안성산업대학교 1968 論文集 Vol.2 No.-

        以上의 調査結果에 依하면 表土가 砂質壤土에 있어서 一般에 準한 作業이고 1m2當 800∼1000本을 殘存시킨 一年生 리기다소나무의 斷根前의 T/R率은 約1.2이며 12cm로 斷根한 後의 1.60∼1.65程度인데 幹長이 길수록 T/R率을 增加하는 傾向이 있음을 알 수 있다. 측백나무 斷根前의 T/R率은 1.3∼1.45程度이고 斷根後에는 1.6∼1.8程度에 達하여 亦是 幹長의 增加에 따라서 T/R率도 增加하게되는 傾向이 있다. 이상 두 樹種을 通하여 우리가 알 수 있는 것은 大體的으로 幹長에 關係할 것 없이 根部重量과 幹部重量間에는 一定한 比率로 地下部의 發達과 地上部의 發達은 相互密接한 相關을 가졌다는 点이다. 本 調査의 試料로 使用된 各樹種의 發育狀態는 良好한 便이며 砂質壤土에 學生들의 實習을 通하여 자조 除草 및 中耕作業을 實施하며 또 斷根前後의 各T/R率의 較差가 적으면 적을수록 그 苗木의 栽培樣式은 優良하다는 意味며 移植作業과 斷根作業의 目的도 여기에 있으며 이 調査에 있어서 얻어진 各各의 T/R의 結果는 그 苗木의 質을 판단할 수 없다. 다만 재배양식 토양조건 地方에 따른 기상조건의 相異한 경우에 양성된 苗木을 相互比較할 때 T/R率이 苗木形質 判斷基準으로서 價値가 있는 것이다.

      • 리기다소나무 立木의 水分分布에 關하여

        韓關錫 안성산업대학교 1967 論文集 Vol.1 No.-

        이 試驗은 리기다소나무의 材部分別 含有水分量을 調査하기 위하여 實施된 試驗인데 調査된 材部分은 乾材에서 心材와 邊材 그리고 枝材, 末木材, 根材 等이다. 이 試驗에서 使用한 試驗木과 測定된 材部分別 平均含水率値는 Table(1),(2)와 같고 다음과 같은 結論를 얻었다. ① 리기다소나무의 冬季伐木材의 各材部中에서 含水率이 가장 높은 部分은 末木材이었고 가장 낮은 部分은 心材이었다. ② 材部分別 含水率을 比較하여 보면 根材와 枝材間 그리고 根材와 邊材間에는 差異가 없었고 末木材와 基他材部間 그리고 心材와 基他 材部間에는 差異가 있었다. ③ 個體間의 材部分別 平均含水率 間에는 一般的으로 큰 變異가 없으나 枝材에서는 매우 큰 變異를 나타낸다. ④ 本硏究論文은 硏究期間中 서울大學校 農科大學 助敎授 李弼宇 先生任의 지도를 받은 것이다. This experiment was carried out to study moisture distribution is standing Pitch Pine trees The moisture measuing samples were made from the parts of root, branch, top, sap and heartwood. The test trees and average moisture contents measured from the parts of trees are as Table (1) and (2). According. to the results this study may be oncluded as followings. 1) In the winter felled Pitch Pine tree highest moisture contents are shown in the topwood but lowest in the heartwood among the parts of tree. 2) In comparing moisture contents showing between two parts of tree, significant differences are shown between top or heartwood and other parts but between branch or sapwood and root are not shown. 3) As general there is no significant variation in moisture contents of root, top, sap and heartwood among test but branch wood is shown considerable variation.

        Prevalence of Detection of Prohibited Drugs on Doping Tests of Pre- and Post-races in Korea (2002-2013)

        양재혁,한관석,양영진,임윤규 한국임상수의학회 2015 한국임상수의학회지 Vol.32 No.2

        There was no study on the prevalence of doping control of racehorses in Korea. The purpose of this study was to determine prohibited substances in horse races of a drugs testing program. Blood samples were taken from those 298,543 starters prior to racing and the that finished top 3 runners of each race and horses designated by the stewards shall be taken for collection of 91,482 urine samples for the purpose of post-race doping test in Seoul, Busan and Jeju Race Park between 2002 and 2013. Detection and measurement of prohibited substances were carried out by ELISA, GC/MS and LC/MS using standard methods at the Doping Control Center, Korea Racing Authority. Total 0.0030% of pre-races and total 0.0186% of post-races tested positive for prohibited substances. In pre- and post-race, caffeine and ketoprofen were the most detected prohibited substance respectively. We thought that characteristics of pharmacokinetics and pharmacodynamics of drugs resulted in different between plasma and urine. These substances have also been detected with other prohibited drugs suggesting that unintentional feeding or bedding may be the reason and groomers’ confusion of candidate horses based by the stewards’ research.

        리기다소나무 입목의 수분분포에 관하여

        이필우,한관석 한국임학회 1968 한국산림과학회지 Vol.7 No.1

        This experiment was carried out to study moisture contents including in the woody parts of standing Pitch Pine trees. The moisture measuring samples were made from the parts of root, branch, top, sapwood and heartwood of test trees. The test trees and average moisture contents measured from the parts of trees are as table (1) and (2). According to the results this study may be concluded as followings. 1) In the winter felled Pitch Pine trees highest moisture contents are shown in the top wood but lowest in the heartwood among the parts of tree. 2) In comparing moisture contents showing between two parts of tree, significant differences are show between top or heartwood and other parts but between branch or sapwood and root are not shown. 3) As general there is no significant variation in moisture contents of root, sapwood and heartwood among the test trees but branch wood is shown considerable variation.
