와송(瓦松)은 바위솔(Orostachys japonicus A. Berger)이라 하며 일명 암송(岩松), 옥송(屋松), 작엽하초(昨葉何草)등으로 불리는 돌나물과(Crassulaceae)의 다년생 초본 식물로서 한방에서 해열, 소종, 지혈, 이습 등에 사용되며[金在佶, 1984, 原色天然藥物大事典(上卷), 南山堂, 서울, p.447] 민간요법으로 암치료에도 많이 이용되고 있다[배성식, 1990, 한방과 건강, 1, 26].Wasong is a perennial herbaceous plant of Crassulaceae, also known as Orostachys japonicus A. Berger, also known as Amsong, Oksong, and Leafy Herb. It is used for fever, swelling, hemostasis, and diarrhea in Korea.

이 식물은 바위 곁에 붙어서 자라는 육질의 다년생 초본이지만 꽃이 피고 열매를 맺으면 고사하는 특징이 있다. 근생엽은 로제트형으로 퍼지며 끝이 굳어져서 가시처럼 되고 원줄기에 잎이 달리며 엽병이 없고 여름철에 나오는 근생엽과 더불어 끝이 굳어지지 않고 다만 뾰족해질 뿐이며 피침형으로서 녹색이지만 자주색 또는 분을 칠한 듯한 백색인 것도 있다. 꽃은 9월에 피고 백색이며 총상화서는 길이 6∼15cm로서 화병이 없는 꽃이 밀착하고 포는 피침형이며 끝이 뾰족하다. 꽃받침은 5개로서 피침형이고 녹색이며 꽃잎도 5개로서 피침형 예두이고 길이 6mm 정도이다. 수술은 10개이며 꽃잎보다 길고 자방은 5개이며 화분은 적색이지만 점차 흑색으로 된다[이창복, 1979, 大韓植物圖鑑, 鄕文社 서울, p.402]. 와송은 여름부터 가을에 걸쳐 채취하며 뿌리를 제거한 전초(全草)를 햇볕에 말려 약용으로 한다[金在佶, 1984, 原色天然藥物大事典(上卷), 南山堂, 서울, p.447].This plant is a fleshy perennial herb that grows by the side of a rock, but it is characterized by flowering and fruiting. The rosettes are rosette-like, and the ends are hardened and become like thorns. The leaves are in the main stem, there are no foliar leaves, and the rosettes coming out in the summer are not stiffened and just pointed. have. Flowers bloom in September, white, total inflorescence is 6-15cm long, without flowers, close to the flowers, lanceolate, and pointed. 5 sepals are lanceolate, green, 5 petals, lanceolate acute, 6mm long. There are 10 stamens, longer than petals, 5 ovaries, and pots are red, but gradually become black [Lee Chang-bok, 1979, 大 韓 植物 圖鑑, 鄕 文 社 Seoul, p.402]. Wasong is harvested from summer to autumn, and dried root-extracted vinegar is medicinal [金 在 佶, 1984, 原色 天然 藥物 大事 典 (上 卷), Namsan Mountain, Seoul, p.447]. .
와송을 본초학적으로 문헌을 통하여 고찰하여 보면 당본초(唐本草)에는 구중(口中)의 건조(乾燥)와 통증에 사용한다고 하며 본초강목에는 대장하혈에 물로 추출하여 복용하고, 모든 상처에 도포하면 수렴 효과가 있다고 하며 본초재신에는 백독(百毒)을 치료하고 종(腫)을 소실시키며 분류초약성에는 치질의 종통출혈을 다스리는 데는 약초를 전액(煎液)으로하여 세척한다고 하며 본초재신에는 창(瘡)과 유(癒)에 효과가 있다고 한다[上海科學技術出版社 小學館編 ; 中藥大事典, 小學館, 1985, p.526].If you look through the literature through the literature, it is said that Dangboncho is used for dryness and pain in the mouth. In the herbal herb, it is extracted with water in colonic hemorrhage and applied to all wounds. It is said to have a converging effect. Herbal rehabilitation treats white poison and kills the species, and classifies herbicides to treat hemorrhoidal hemorrhage and to wash the herb in full amount. It is said to have an effect on 과 and [[上海 科學 技術 出版社 小學 館 編;中藥 大事 典, 小學 館, 1985, p.526].

실험예 1 : 실험 동물 사육 및 당뇨 유발Experimental Example 1 Breeding Experiment Animals and Inducing Diabetes
실험 동물 사육Breeding experimental animals
체중이 200∼230g인 7주령의 스프라그 다우리(Sprague-Dawley)계 수컷 흰쥐를 구입하여 일주일간 고형 배합사료를 주면서 예비 사육하였다. 적응 기간이 지난 후 당뇨병을 유발시켜 체중과 혈당농도를 고려하여 정상 대조군(Normal-Cont), 당뇨 실험군[당뇨 대조군(Db-Cont), 와송군(Db-OJP1)]으로 나누어 4주간 사육하였다. 실험기간 동안 실험동물의 식이와 물은 자유롭게 섭취(ad libitum)할 수 있게 하며, 사료 섭취량과 체중은 일주일 간격으로 측정하였다. 실험동물의 사육 조건은 실내온도 22±2℃, 습도 55±5%, 명암은 12시간(Day light 06:00∼18:00)을 주기로 조절하였다.Seven-week old Sprague-Dawley male rats weighing 200-230 g were purchased and pre- bred with solid feed for a week. After the acclimatization period, diabetes was induced and divided into a normal control group (Normal-Cont), a diabetic experimental group (diabetic control group (Db-Cont), and Wahson group (Db-OJP1)) in consideration of body weight and blood glucose concentration. During the experimental period, the diet and water of the experimental animals were freely taken (ad libitum). Feed intake and body weight were measured at weekly intervals. The breeding conditions of the experimental animals were controlled at room temperature of 22 ± 2 ℃, humidity of 55 ± 5%, and contrast for 12 hours (day light 06: 00-18: 00).
실험 식이Experimental diet
동물실험용 식이는 정상 대조군과 당뇨 대조군은 분말사료를 사용하였고 와송군의 경우는 1% OJP1을 사용하였다.For animal experiments, the normal control and diabetic control group used powdered feed and the Wasong group used 1% OJP1.
당뇨 유발Diabetes
당뇨 유발은 예비 사육 일주일 후, 다른 기관에는 영향을 주지 않고 췌장의 베타-세포(β-cell)에만 작용하여 파괴시켜 투여 24시간 이내에 인슐린 결핍에 의해 고혈당을 유발시키는 것으로 알려져 있는 스트렙토조톡신(streptozotocin)(STZ, Sigma Chemical Co., St. Louise, U.S.A)을 사용하였다. 0.01M 시트르산 완충액(citric acid buffer)(pH 4.5)에 녹여 55mg/kg의 농도로 1회 복강 주사하고 3일 후 12시간 절식시킨 후 꼬리정맥에서 채혈하여 혈당농도가 200mg/dL 이상인 것들만 당뇨쥐로 사용하였다.Diabetes induced streptozotocin, which is known to cause hyperglycemia due to insulin deficiency within 24 hours after administration, destroying by acting only on beta-cells of the pancreas without affecting other organs after one week of preliminary breeding. ) (STZ, Sigma Chemical Co., St. Louise, USA) was used. Dissolved in 0.01M citric acid buffer (pH 4.5) and intraperitoneally injected at a concentration of 55mg / kg, fasted 12 hours after 3 days, and collected from the tail vein to collect blood glucose levels above 200mg / dL.

혈액 채취Blood collection
초기 혈액의 채취는 실험 첫날에 실험동물을 12시간 절식시킨 뒤, 꼬리정맥에서 채취하였다. 실험 사육 4주가 되는 마지막 날에 실험동물을 12시간동안 절식시킨 후, 300mg/mL의 우레탄(Urethane)(Sigma Chemical Co., St. Louise, U.S.A)을 복강에 주사하여 마취시켜 희생시켰다. 실험동물의 복강 대정맥에서 혈액을 채취한 후, 원심분리(6,000rpm, 4℃, 15min)하여 상등액으로부터 혈청을 분리하여 냉동보관하였다.Initial blood was collected from the tail vein after fasting the animals 12 hours on the first day of the experiment. After the animals were fasted for 12 hours on the last day of 4 weeks of breeding, 300 mg / mL urethane (Sigma Chemical Co., St. Louise, U.S.A) was injected into the abdominal cavity for anesthesia and sacrificed. Blood was collected from the abdominal vena cava of experimental animals, and centrifuged (6,000 rpm, 4 ° C., 15 min) to separate serum from the supernatant and stored frozen.
혈당 측정Blood sugar measurement

스트렙토조톡신(Streptozotocin)으로 유발 시킨 SD 당뇨 쥐에 1% OJP1을 4주간 공급하여 항당뇨 효과를 확인한 결과, 실험 시작 전과 종료 후 와송군에서 혈당(plasma glucose), 혈청 트리글리세라이드(serum triglyceride), 혈청 총 콜레스테롤 수치(serum total cholesterol level)는 당뇨대조군에서보다 유의적으로 감소하였다(표 2, 도 1~4). 혈청 HDL-콜레스테롤 수치(serum HDL-cholesterol level)는 당뇨대조군과 비교하였을때 증가하는 추세를 나타내었다(p=0.083). 따라서, OJP1은 당뇨 쥐에 혈당저하, 중성지방저하 및 콜레스테롤저하 등에 효과가 있음이 확인되었다.The antidiabetic effect was confirmed by supplying 1% OJP1 for 4 weeks to SD diabetic rats induced with Streptozotocin. Plasma glucose, serum triglyceride, serum triglyceride, Serum total cholesterol level was significantly reduced than in the diabetic control group (Table 2, Figures 1-4). Serum HDL-cholesterol levels showed an increasing trend compared to the diabetic control group (p = 0.083). Therefore, it was confirmed that OJP1 is effective in lowering blood sugar, lowering triglyceride and lowering cholesterol in diabetic rats.
