早強ポルトランドセメントおよび高炉スラグ微粉末を用いたペーストにCaO·2Al2O3を混和することによってセメント水和物である水酸化カルシウムが反応してハイドロカルマイト族の水和物を生成し,外部から浸透した塩化物イオンを化学的に固定化する効果と,細孔空隙率を小さくする物理的な浸透抑制効果が確認された.これによってペーストの塩化物イオンの見かけの拡散係数が大幅に低減された.この効果について初期養生温度が60℃の場合は低くなる傾向を示したが,中性化を受けた場合はほとんど変わらなかった.

Erectile dysfunction following radical prostatectomy (RP) is still a significant burden as a post-operative morbidity, despite advances in nerve-sparing techniques and penile (erectile function) rehabilitation (PR) programs. We assessed the effects of stimulation with the masturbation device "EGG" on enhancement of erectile response along with administration of phospho diesterase type 5 inhibitor. We also studied the change of self-esteem and motivation for continuation of PR after stimulation with EGG. Eight nonresponders for PDE5-I who underwent retropubic RP were enrolled. Patients' median age was 71.5 years old. No patients received adjuvant therapy for prostate cancer. The patients' erectile response in the penile rehabilitation session (masturbation) with PDE5-I+manual stimulation and PDE5-I+stimulation with EGG were evaluated by erection hardness score (EHS). Changes of self-esteem and motivation for penile rehabilitation were assessed by the self-esteem subscale of the Self-Esteem and Relationship (SEAR) questionnaire and one original question, respectively. PDE5-I + stimulation with EGG significantly enhanced EHS compared to PDE5-I+manual stimulation in the eight patients (p=0.027). Transformed score of self-esteem subscale score of SEAR questionnaire was significantly increased in the PR session with EGG compared to the PR session with manual stimulation (p=0.043). Six patients who showed a better erectile response with EGG retained motivation for continuation of PR. PDE5-I+stimulation with EGG improved the erectile response in post-RP patients. EGG as a masturbation device may have a potential for contribution to successful PR.
