Successful hyperbaric oxygen therapy for refractory BK virus-associated hemorrhagic cystitis after cord blood transplantation.

BK virus-associated hemorrhagic cystitis (BKV-HC) is a common and major cause of morbidity in recipients of allogeneic hematopoietic stem cell transplantation. A 32-year-old woman developed severe BKV-HC on day 24 after cord blood transplantation (CBT). Despite supportive therapies - such as hyperhydration, forced diuresis, and urinary catheterization - macroscopic hematuria and bladder irritation persisted for over a month. Hyperbaric oxygen (HBO) therapy at 2.1 atmospheres for 90 min per day was started on day 64 after CBT. Macroscopic hematuria resolved within a week, and microscopic hematuria was no longer detectable within 2 weeks. Hematuria did not recur after 11 sessions of HBO therapy, and no significant side effects were observed during or after treatment. HBO therapy could thus be useful in controlling refractory BKV-HC after CBT.

Selection of absorption lines for I(2)-planar laser-induced fluorescence measurement of temperature in a compressible flow.

It is very important for I(2)-planar laser-induced fluorescence measurement of temperature in a compressible flow to choose a pair of absorption lines appropriate to the temperature range. The method for selection of suitable pairs of absorption lines of I(2) in the transition of B(3)II(ou) + (ν' = 43) ? X(1)Σ(g) + (ν" = 0)is described. By the use of many pairs of absorption lines, the temperature dependence of the ratio between the fluorescence signals is calculated theoretically and is also investigated in experiments in which several pairs are applied to determination of the temperature distribution of a supersonic free jet.

Method for planar measurement of temperature in compressible flow using two-line laser-induced iodine fluorescence.

A method for planar measurement of temperature in a compressible flow by means of two-line laser-induced iodine fluorescence is proposed. Temperature is determined from the ratio of the intensities of fluorescence, which are obtained by irradiation of two laser beams of different wavelength. Use of a high-sensitivity vidicon camera permits multiple-point measurements of temperature in the flow field. This method is applied to a supersonic free jet. It is found that the results obtained by P(16)/R(18) (514.720 nm) and P(26)/R(28) (514.942 nm) absorption lines in the transition of B(3)II(ou)+ (nu' = 43) ? X(1)sigma(g)+ (nu'' = 0) can predict temperature below 300 K with an accuracy of +/-5K.
