A route for repeat leveling survey was established around Syowa Station (69° S, 39° E), East Ongul Island, Antarctica in 1979 and 1982. The leveling measurements were repeated in 1996. However only 2.3 km out of the total length of 5.3 km route was surveyed for the time limitation during the summer operation of the 37th Japanese Antarctic Research Expedition (DARE-37). The other part of the route was measured by DARE-38 in February 1997. In total, the discrepancy of forwardand backward leveling, and closing error of the measurement circuit, were obtained within the limitation of the first order leveling of the Geographical Survey Institute. However the measurement between BM 1029-BM 1030 was 0.6 mm out of the limitation. This was seemed to be caused by change of the field condition. There are two ponds named Midoriike and Kamome-ike between the two bench marks. Water overflowed from Kamome-ike to Midoriike during summer seasons in 1996 and 1997. Leveling survey had to be done in the water. This worst condition must be the reason of the measurement between BM 1029 and BM 1030 over the limitation. Except the results between BM 1029-BM 1030, no appreciable changes along the east-west direction (BM 1040-BM 1026) and the north-south direction (BM 1026-BM 1029) were observed for the last 15 years. It is inferred from geomorphological andgeophysical data that the crust around Syowa Station continues to uplift after deglaciation. The observations from repeat leveling measurements suggest no significant changes, which further supports the idea that the crustal uplift is a block movement.

Nitrosourea系制癌剤のNimustine HydrochlorideからHydrochlorideを除去したNimustine50mgとLipiodo110m1との懸濁液(N-L液)の癌局注療法における原発巣及びリンパ節転移に対しての抗腫瘍効果について検討した.【材料と方法】(1)C57Black/6 MouseにLewis Lung Cancerを移植,N-L液,MitomycinC, Adriamycin, Oil bleoをそれぞれ移植腫瘍内に局注して,その直接的抗腫瘍効果を比較検討した.(2)同様にN-L液局注後のDNA Histogramの変動をFlow cytometryを用い測定した.(3)ICR Mouseの足底部にSarcoma180を移植し,リンパ節転移に対するN-L液の抑制効果を検討した.【結果】(1)N-L液の直接的抗腫瘍効果が最も強かった.(2)DNA Histogramの変動は,局注前と比較し局注後G0-1期の比率が減少し,S期,G2-M期の比率が上昇した.(3)N-L液はリンパ節転移抑制効果を認めた.【結論】N-L液の局注療法は原発巣だけでなくリンパ節転移に対しても抗腫瘍効果が認められた.

胆汁性仮性嚢胞(biloma)は,肝あるいは胆道系の外傷や手術後合併症として,また経皮経肝胆道造影やドレナージなどによって,胆汁が肝被膜下などに被覆された状態で流出し形成された2次的嚢胞であり,1979年にGouldらにより初めて記載された.しかしながら,このような既往なしに発症することもまれながら報告されている.われわれは胆嚢炎の穿通が原因となったbilomaを3例経験した.1例は手術までの比較的短期間にbilomaが消失した興味ある症例であり,また他の1例は手術前にbilomaをドレナージしたが,症状は軽快せず手術にて完治した症例であった.残る1例は原因となった胆嚢を穿刺ドレナージすることでbilomaが消失した症例である.これら3例の経験から,胆嚢炎の消退により流出した胆汁(biloma)は,胆嚢に還流することで自然消失することが示唆され,胆嚢炎が原因となったbilomaは,まず胆嚢炎に対する何らかのアプローチが大切であると考えられた.
