Prior thoracic radiotherapy and pre-existing PF were correlated with higher ILD rate in gemcitabine-treated patients. ILD incidence did not differ between NSCLC and pancreatic cancer patients, which may be due to the differences in treatment strategy and tumour properties.

Cytarabine ocfosfate (SPAC) was administered orally to 19 patients with acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS). SPAC was administered at doses of 200-300 mg/day for more than 14 days with granulocyte colony-stimulating factor (G-CSF). Four of the 12 patients with AML and 1 of the 7 patients with MDS achieved complete remission (CR) after one cycle of SPAC treatment. Especially, 3 of the 6 patients with newly diagnosed AML achieved CR. Major side effects of SPAC were myelosuppression and tolerable gastrointestinal disorders. The treatment with SPAC is a therapeutic option in elderly patients or patients with organ failure.

Abstract. The present study investigated whether substitution of HEPES for bicarbonate in BTS (BTS-H) used to dilute boar ejaculates immediately after ejaculation could reduce the increased inducibility of the acrosome reaction by calcium and calcium ionophore A23187. When an ejaculate was split, diluted 5-fold with regular BTS (BTS-B) and BTS-H and stored at 17 C for 12 h or 60 h, the extender or storage time had no significant influence on sperm motility or viability measured by the eosin-nigrosin method. When spermatozoa diluted serially with BTS-B and stored (36 h) were stimulated with Ca 2+ (3 mM) and A23187 (0.3 μM), the proportion of spermatozoa that underwent the acrosome reaction (% acrosome reactions) significantly increased as the magnifications of dilution increased (bicarbonate content almost unchanged by dilution). By contrast, the % acrosome reactions in spermatozoa similarly diluted and stored with BTS-H decreased with the increasing magnifications of dilution (bicarbonate decreased). Sperm motility immediately after the end of incubation without A23178 tended to be lower for BTS-H than BTS-B, and the ejaculates for BTS-H had a tendency to have a lower total protein in seminal plasma than those for BTS-B. These results implied that the samples for BTS-H could be used as a model for ejaculates possibly collected during summer and showing subfertility. When an ejaculate was split, diluted serially with BTS-B and BTS-H and stored, viability measured by staining with propidium iodide was extremely similar between the 2 extenders and among the different dilution magnifications, regardless of whether spermatozoa were washed (stored for 36-66 h) or not (stored for 66-72 h). These results suggest that boar ejaculate can be stored with BTS-H at least according to the results for sperm motility and viability and that hypersensitivity of spermatozoa to Ca 2+ and A23187 potentially associated with boar subfertility could be lessened by diluting ejaculates with BTS-H. Key words: Acrosome reaction, Bicarbonate, Boar, Spermatozoa, Storage (J. Reprod. Dev. 56: [309][310][311][312][313][314] 2010) rtificial insemination with liquid-stored semen is important for pig production, but seasonal infertility associated with reduction of fertility and litter size during summer has been long known [1,2]. Our previous results showed that during summer, stored boar spermatozoa underwent the acrosome reaction in response to calcium and calcium ionophore A23187 more quickly than other periods, the total protein concentration in seminal plasma decreased and the farrowing rate was the lowest [3]. We considered that the quicker response of spermatozoa may be associated with membrane destabilization due to a reduced protein content during storage. On the other hand, it is also known that bicarbonate destabilizes the sperm plasma membrane leading to facilitation of capacitation processes [4][5][6]. Dilution with an extender reduces the concentrations of proteins present in seminal plasma, destabilizing the membrane and leading ...
