Abstract

In order to evaluate the effect of water soluble extract of lichens (Physcia, Parmelia and Clandonia species) on liver damage, activities transaminase(GPT) and 5'-nucleotidase in serum and liver were measured in rats fed lichens extract. DNA and RNA were measured in liver and spleen, as well as various organ weights and blood components. Control group was fed water to compare with the lichen group. Three sets of experiments were conducted: the first set was done with normal rats, the second one with rats with liver damage induced by $CCl_4$ injection was divided into three subgroups. i.e. no treatment group, pre-treatment group and post-treatment group, and the third one was with rats with acute and chronic liver damage. In normal rats, lichens extract feeding reduced serum GOT and GPT activities. In liver damaged rats, both pre-and post-treatment had suppressing effect against increase of serum enzymes. In rats with acute and chronic liver damage, lichens fed group had lower activities of serum GOT, GPT and 5'-nucleotidase but higher activities of liver enzymes than control group. This effect was more pronounced in rats with acute liver damage. Liver weight increased considerably with lichens intake. Hemoglobin and hematocrit levels were also higher in lichens fed group. Nucleic acid contents in spleen but not in liver were increased in lichens fed group. The latter increase was more significant with chronic liver damage. It is suggested from the present study that water soluble lichens extract play protective and therapeutic roles in organs against infection and atrophic disease.

지의류(地衣類)의 수용성 추출물이 간손상에 미치는 효과를 조사하고자 지의류 추출물을 투여한 실험군과 물을 준 대조군으로 나누어 사육하면서 흰쥐 체내의 체중 및 각 장기무게, GOT, GPT 및 5'-nucleotidase의 활성을 측정하였다. 실험은 3차에 걸쳐 행하였는데 제1차 실험은 정상 쥐에게 지의류(地衣類)를 투여하였고, 제2차 실험은 지의류(地衣類) 투여에 따라 무처리(無處理), 전처리(前處理), 후처리(後處理)군으로 나눈 후 흰쥐들에게 $CCl_4$를 주사하여 1주일동안 변화를 측정하였으며, 제3차 실험은 $CCl_4$에 의한 급성 및 만성 간손상을 가진 쥐들에게서 지의류(地衣類) 추출물의 효과를 관찰한 결과를 요약하면 다음과 같다. 정상 쥐의 혈청내 GOT 및 GPT 활성은 실험군이 대조군보다 비교적 낮았으며 간손상 유도시 지의류(地衣類) 전처리(前處理)군 및 후처리(後處理)군에서 혈청내 효소활성 상승 억제효과를 볼 수 있었다. 급성 간손상시 실험군의 혈청내 효소활성도가 낮았으나 간장조직내의 GOT 활성은 실험군이 대체로 높았으며 GPT 활성은 두군간에 별 차이가 없었다. 5'-nucleotidase는 GOT와 같은 경향이었다. 혈청내 효소량을 낮게 유지하는데 만성장애시 보다 급성장애시 더 효과적이었으며 간장조직내 효소의 상대적 변화는 혈청에 비해 적었다. 각 장기무게는 정상쥐에서는 특이한 점이 없었으나 $CCl_4$ 주사 후 지의류 추출물을 투여했을 때 대조군에 비해 실험군의 간장무게가 증가하였다. 간장 및 비장의 핵산함량과 적혈구, 백혈구 및 hemoglobin 양도 실험군에서 높았다.
