53歳, 女性。2005年12月, 子宮体癌に対してパクリタキセル, カルボプラチンが投与された。2006年4月, 手指の浮腫が出現。2007年2月より手指の硬化を認め, 徐々に前腕にも拡大したため近医皮膚科を受診した。全身性強皮症を疑われ, 同年7月当科初診し, 臨床症状, 各種検査により全身性強皮症と診断された。プレドニゾロン20mg/日の投与を開始し皮膚硬化は軽快した。経過より全身性強皮症の発症にパクリタキセルの関与が疑われた。

Increased Plasma Levels of Platelet Factor 4 and β-thromboglobulin in Women with Recurrent Pregnancy Loss.

Sayoko Kotani Yasuhiko Kamada Keiko Shimizu Ai Sakamoto Mikiya Nakatsuka

Thrombosis in decidual vessels is one of the mechanisms of pregnancy loss. However, few studies have assessed the relation between platelet activation, which is known to cause of thrombosis, and recurrent pregnancy loss (RPL). We investigated platelet activation in women with RPL compared to controls by measuring plasma levels of platelet factor 4 (PF4) and β-thromboglobulin (βTG), and assessed correlations between PF4/βTG and coagulative risk factors associated with RPL. The study group included 135 women who had experienced two or more consecutive pregnancy losses. The control group included 28 age-matched healthy women who had never experienced pregnancy loss. PF4 and βTG plasma levels were significantly higher in the women with RPL than controls (PF4: 14.0 [8.0-20.0] vs. 9.0 [6.0-12.0] ng/ml, p=0.043; βTG: 42.0 [24.3-59.8] vs. 31.5 [26.6-36.4] ng/ml, p=0.002). There was a significant association between βTG and anti-phosphatidylethanolamine antibody immunoglobulin M (aPE IgM) (p=0.048). Among the women with RPL, 18 of those who were positive for PF4 (45%) and 18 of those who were positive for βTG (37%) were negative for all known coagulative risk factors associated with RPL. Measurements of PF4 and βTG may be important because they help identify women who are at risk of RPL.

Millimeter-wave spectroscopy of the FeCO radical in the ν2 and ν3 vibrationally excited states

The Journal of Chemical Physics (2015)

Kéiichi Tanaka Mitsuhiro Nakamura Mitsuaki Shirasaka Ai Sakamoto Kensuke Harada

The pure rotational spectra of the FeCO radical in the ν2 (bending) and ν3 (Fe-C stretching) vibrational states of the ground X̃(3)Σ(-) electronic state were observed in the millimeter-wave region. The equilibrium rotational and centrifugal distortion constants were determined to be Be = 4374.631 (58) MHz and De = 1.1666 (20) kHz together with the spin-spin coupling constant λe = 691.89 (37) GHz and spin-rotation coupling constant γe = - 1079.4 (55) MHz with use of the millimeter-wave results and the ν1 IR data. The equilibrium bond length for Fe-C was derived to be 1.725 Å assuming that for C-O to be 1.159 Å. Since the vibronic symmetry of the excited state of bending vibration is (3)Π, the analysis of spectrum in the ν2 state required an effective spin-orbit interaction constant of A2 = 6.0219 (61) GHz together with three parity doubling constants of o2 = 36.168 (10) GHz, p2 = 85.18 (34) MHz, and q2 = 4.7024 (17) MHz. The effective spin-orbit interaction constant A2 is attributed to the vibronic mixing of the (3)Π excited electronic states. The vibronic mixing also cause the parity doubling constants o2 and p2, but the main contribution to q2 is given by the vibrational l-type doubling.
