    MRアンギオグラフィーの描出能を向上させる目的で,薄いスラブの積み重ねによる頭部MRアンギオグラフィーを試みた.さらに,presaturation法との併用効果についても検討した.マルチスラブ法の方が細かな血管がより多数観察され,中大脳動脈穿通枝の連続性が優れていた.presaturation法との併用により良好な動脈像,静脈像が得られた.流体ファントム実験(毎秒10cmの定常流)では,1スラブの場合には流出側で急激に信号が減衰したのに対して3スラブの場合には信号の減弱はみられなかった.

    副鼻腔嚢胞は,術後性嚢胞を含めると上顎洞嚢胞が最も多く,ついで前頭洞,筋骨洞の順であるといわれる.とくに前頭洞嚢胞は約半数の症例において副鼻腔手術の既往がなく,眼部症状を初発症状とし,鼻症状を欠くため,眼科を受診することが多い.最近,われわれは,眼球突出,複視を主訴とした巨大前頭洞嚢胞を経験したので報告する.症例は69歳,男性.徐々に進行する右の眼球突出と瞼裂低位がみられ,複視,流涙を来すようになり,近医眼科を受診した.術前MRIにて右前頭葉を圧排,右簾骨洞,眼窩に進展した巨大前頭洞嚢胞が確認され,手術目的にて当科紹介となった.手術は両側前頭開頭にて嚢胞切除を行ったが,前頭葉硬膜と嚢胞壁の剥離が困難であり,一部硬膜損傷を来した.嚢胞切除後は一部残存する菲薄化した前頭洞後壁を除去,前頭蓋底と副鼻腔を遮断すべく,頭蓋骨膜弁を挙上,再建を行った.術後,一時的に前頭葉徴候がみられたが,術前に見られた眼症状は消失し,整容的にも満足する結果が得られた.

    The urea rebound phenomenon (Ru) after hemodialysis has been reported recently. The present study was made in an attempt to clarify the influence of Ru on normalized dialyser urea clearance (Kt/V'), time averaged concentration of blood urea nitrogen (TACBUN) and protein catabolic rate (PCR). A significant correlation was found between the Ru and Kt/V, while no significant correlation was seen between the Ru and PCR. These results indicate that the Ru is dependent on the efficiency of hemodialysis. The different values of Kt/V, TACBUN and PCR were calcuated using BUN values at the end of hemodialysis and 30min after dialysis, and compared. When calculating Kt/V, PCR and TACBUN using BUN values obtained immediately after hemodialysis, Kt/V and PCR were overestimated by about 15.6% and 8.5%, respectively, and TACBUN was underestimated by 4%. These results indicate the necessity of taking the Ru into account when determining whether or not the patient is receiving optimal dialysis.

    Advances in the hemodialysis therapy have been made recent years. It is, however, still important for chronic hemodialysis patients to control the diet and water intake. So, in 76 patients who had been on chronic hemodialysis for more than one year, we analyzed absolute weight gain (gain during the two-day interval between two sessions of hemodialysis) and percentage of weight gain [(absolute weight gain/dry weight) × 100] in relation to normalized dialysis urea clearance (Kt/V), time averaged concentration of blood urea nitrogen (TACBUN) and protein catabolic rate (PCR), and also in relation to protein, energy, salt and potassium intake.
    PCR had a signifi cant correlation with both the absolute weight gain (r=0.329,P<0.01) and the percentage of weight gain (r=0.349,P<0.01). Protein, energy, salt and potassium intake also correlated significantly with bothparameters. These results suggest that weight gain is closely rlated to the amount of food intake like water intake.
    Dry weight (DW) cor related significantly with absolute weight gain (r=0.392,P<0.0005), while it did not correlate significantly with percentage of weight gain. This suggests that patients with large DW tend to be inappropriately restricted as to their water intake to counter weight gain acthually caused by excessive food ingestion, and that patients with small DW tend to be erroneously subjected to an excessively limited diet for the purpose of suppressing weight gain.
