<b>Effect of Hachimijiogan for Male Lower Urinary Tract Symptoms</b> / 日本東洋医学雑誌

We evaluated the effect of hachimijiogan in 30 cases of anticholinergic agent and α-blocker resistant LUTS. International Prostate Symptom Scores (IPSS), QOL scores, Benign Prostatic Hyperplasia Impact Index (BII) scores and urinary 8-OHdG of the patients were statistically much improved. This study demonstrated improvement in urinary symptoms, urinary QOL and oxidative stress, in LUTS resistant to anticholinergic agents and α-blockers. Further long-term studies will be needed not only in urinary symptoms, but also in effect as an anti-aging medicine.

<b>Effect of Hachimijiogan and its Additional Prescription for Anticholinergic Agent-resistant Overactive Bladder </b> / 日本東洋医学雑誌

We evaluated the effects of Hachimijiougan and its additional prescription in 11 cases of anticholinergic agent-resistant overactive bladder. The improvements in IPSS, QOL score, BII score and urinary 8-OHdG for the patients were statistically much improved. This study showed improvements of urinary symptoms and QOL in anticholinergic agent-resistant overactive bladder. Further long-term studies will be needed not only in urinary symptoms but also on effects as an anti-aging medicine.

Augmentation of eccentric strength of knee extensors with teeth clenching / 体力科学

Previous research has demonstrated that the concentric muscle strength of knee extension exerted at slow to medium angular velocities is increased by teeth clenching. This study evaluated the isokinetic eccentric strength of knee extensors at 4 angular velocities (60, 120, 180 and 240 degrees per second) with and without teeth clenching on the Cybex 6000 Extremity Testing and Rehabilitation System. Twelve healthy adult male (26.8±1.8 years) volunteered for the study. Peak torque per body weight and average power per body weight were analyzed. The results demonstrated that peak torque per body weight accompanied by teeth clenching was significantly increased at 60, 120, 180 and 240 deg/s by 9.5%, 8.2%, 8.2% and 9.8%, respectively (p<0.01) . Similarly average power per body weight during teeth clenching was significantly higher at 60, 120, 180 and 240 deg/s by 9.1%, 9.5%, 9.4% and 7.7%, respectively (p<0.05) . These findings suggest that teeth clenching is a factor that leads to augmented eccentric strength of knee extensors. Its effect appears to be independent of angular velocity.
