정용,이윤실,이효민,Chung, Yong,Lee, Yun-Sil,Lee, Hyo-Min 대한약학회 1987 약학회지 Vol.31 No.4
The earthworm(Annelid) is a herbicine which has traditionally been used in the treatment of infectious fever, jaundice, infection of middle ear, laryngitis, pharyngitis, nephritis, headache, toothache and certain urinary tract infections from the olden times. Before the isolation and purification of biologically active components we analyzed the basic constituents(proteins, amino acids, mineral, etc.) with lyophilized powder of Lamnodrilus gotai Hatai. The results were as follows: Minerals detected and quantitatively analyzed were $Ca^#$, $Mg^#$, Fe, Zn, Mn, Cu, Co, Cr, Ni, Ge and Se. Amino acids detected were alanine, phenylalanine, leucine, glutamic acid, tyrosine, threonine, arginine, aspartic acid, methionine, lysine, serine, histidine, isoleucine, glycine, proline and etc. The constituents of proteins, fat, fiber, ash and phosphorous were measured. These constituents were compared and discussed with those of other investigations.
한국전통생약의 약리작용과 활성물질에 관한 연구(V) -사매(蛇?)의 항균성분획의 페놀성물질-
이인란,이윤실,한용남,Lee, Ihn-Rhan,Lee, Yun-Sil,Han, Yong-Nam 대한약학회 1988 약학회지 Vol.32 No.5
A phenolic compound isolated from the ethylacetate extract of Duchesnea indica (Andr.) Focke (Rosaceae) showed antimicrobial activities against Staphylococcus aureus, Shigella dysentriae and Pseudomonas aeruginosa. This compound was identified as ellagic acid by spectral analysis.

The effects of ionizing radiation on the peripheral blood elements of ICR mouse were examined after varying doses of whole-body gamma-irradiation. ICR mice (n=50) were exposed to 0, 2, 4, 6 and 8 Gy gamma-ray ($^{60}Co$) at 10 Gy/min. The animals were studied for their hematological response on days, 3, 7, 14, 21, 42 and 56 post irradiation. No significant change was noted in erythrocyte, hemoglobin and hematocrit values after irradiation with dose of 2 Gy. Decreasing erythrocyte, hemglobin and hematocrit values occured after irradiation with doses of more than 4 Gy on day 7 after irradiation followed by a sharp fall on day 14. A recovery in these values was noted after 3 weeks of irradiation. Thrombocyte counts decreased on day 3, reaching minimal values on day 7. The total number of leukocytes was reduced on day 3, mainly because of a decrease in the lymphocyte population. An evident lymphopenia and neutropenia occur almost on the day 3 and last up to the day 28 after irradiation. All of the hematological values decreased in the blood in a dose-dependent manner at the same time.
태아시기의 방사선 노출에 의한 마우스 뇌 발달에 미치는 영향에 관한 형태학적 연구

The present study analyze the morphological aspects of the cerebrum of mice with prenatal exposure to high and low dose (0.5, 1, 2 Gy) of $\gamma$-radiation on gestation day 12 or 16. The animal were allowed to give birth and the offspring were sacrificed at postnatal days 28 for gross and microscopic examination of cerebrum. Their body weight, brain weight, brain length, brain width, cortical thickness and area of cingulum bundle were examined. The histological and planimetric analysis were performed observing coronal sections. The gross malfomation (microcephaly) and abnormality of cortical architecture were prominent after exposure to 2 Gy on day 12 of gestation. significant dose-related reductions in body weight, brain weight, brain size were found in all irradiated groups. A significant change was found in thickness of the cerebral cortex and area of the cingulum bundle in the groups exposed to 0.5 Gy or more. There was no difference a lamina patter of six layers in cerebral cortex between the control and irradiated groups, but cell packing density increased significantly in the group exposed to 1 Gy or more. These results suggested that dose as low as 0.5 Gy could cause a morphologically reduce change in developing mouse cerebrum and exposure on day 12 of gestation to $\gamma$-irradiation is a particularly sensitive phase in causing malformation and abnormality of central nerve system.
