To confirm the safety and efficacy of a low-calorie mayonnaise supplemented with phytosterol esters (PEM) at a daily consumption dose of 884 mg given for 12 weeks with the goal of lowering serum low-density lipoprotein (LDL) cholesterol levels, we conducted a double-blind comparative study in healthy adults with marginally high serum levels of LDL cholesterol and total cholesterol using a mayonnaise without phytosterol esters supplementation (CM) as the control food. Serum LDL cholesterol levels decreased significantly in the PEM group as compared with the CM group during the 12-week intervention period (136.3 ± 16.4 vs. 145.0 ± 19.3 mg/dL at Week 8 (P < 0.05) and 135.0 ± 17.4 mg/dL vs. 144.9 ± 17.5 mg/dL at Week 12; P < 0.05). No observable adverse effects were observed due to the ingestion of PEM in this study. The safety of PEM was again confirmed by an additional clinical study in which healthy adult subjects ingested a 3-fold greater amount of PEM (2,652 mg of phytosterol esters as a daily dose) for 4 weeks. Thus, we concluded that PEM is effective in lowing serum levels of LDL cholesterol and is safe and well tolerated without any clinical problems.

PURPOSE: Guided bone regeneration (GBR) is the most widely used technique to regenerate and augment bones. Even though augmented bones (ABs) have been examined histologically in many studies, few studies have been conducted to examine the biological potential of these bones and the healing dynamics following their use. Moreover, whether the bone obtained from the GBR procedure possesses the same functions as the existing autogenous bone is uncertain. In particular, little attention has been paid to the regenerative ability of GBR bone. Therefore, the present study histologically evaluated the regenerative capacity of AB in the occlusive space of a rat guided bone augmentation (GBA) model. METHODS: The calvaria of 30 rats were exposed, and plastic caps were placed on the right of the calvaria in 10 of the 30 rats. After a 12-week healing phase, critical-sized calvarial bone defects (diameter: 5.0 mm) were trephined into the dorsal parietal bone on the left of the calvaria. Bone particles were harvested from the AB or the cortical bone (CB) using a bone scraper and transplanted into the critical defects. RESULTS: The newly generated bone at the defects' edge was evaluated using micro-computed tomography (micro-CT) and histological sections. In the micro-CT analysis, the radiopacity in both the augmented and the CB groups remained high throughout the observational period. In the histological analysis, the closure rate of the CB was significantly higher than in the AB group. The numbers of cells positive for runt-related transcription factor 2 (Runx2) and tartrate-resistant acid phosphatase (TRAP) in the AB group were larger than in the CB group. CONCLUSIONS: The regenerative capacity of AB in the occlusive space of the rat GBA model was confirmed. Within the limitations of this study, the regenerative ability of the AB particulate transplant was inferior to that of the CB particulate transplant.

Aim of the present study was to statistically evaluate the examination rule with use of a questionnaire obtained from physicians regarding treatment for chillness of the limbs, and to prove the clinical usefulness of the database. The database showed that tokishigyakukagoshuyushokyoto was the most frequently used to treat chillness of the limbs, and subsequently keishikajutsubuto, hachimijiogan, and tokishakuyakusan were ranked as drugs with wide use. When physicians determined a kampo formulation suitable for each patient, they used findings specific for the kampo formulation, but not uniform findings obtained from the four traditional examination methods (i.e., inspection, listening and smelling, interviewing, palpitation). There was a statistical difference in the selection mode of drugs among physicians. In a simulation obtained from a questionnaire, there was a positive association between time (time X) to the start of becoming physically warm in the limbs, and time (time Y) to remission (R² = 0.971, P = 0.014). The formula (Y = 4.379 X−0.519), which could predict time Y on the basis of information on time X, was able to accurately monitor the clinical courses of 7 responders to treatment for chillness of the limbs. Taken together, these results strongly suggest that the database constructed in the present study may be useful for evaluation of traditional Kampo medicine, and might allow us to perform more fittingly personalized Kampo medicine in the near future.

BACKGROUND: Both endoscopic ultrasound-guided celiac plexus neurolysis (EUS-CPN) and tumor ablation using ethanol are very common procedures, and the utility of these therapies has already been reported in prominent journals. However, their effectiveness appears temporary and insufficient, especially EUS-CPN. We therefore have to consider new reagents for improving the results. The present study examined the best concentration of ethanol and povidone iodine mixed with atelocollagen for more effective therapies. METHODS: The effects of the new reagents were confirmed in three live pigs. At first, we injected three kinds of reagents (including indigo carmine) in three separate areas of para-aortic tissue under EUS guidance in one pig. At more than 4 hours after injection, we checked ethanol injection sites after dissection. In next study, we performed EUS-guided injection of a total of six kinds of reagents (two kinds of ethanol, three kinds of povidone iodine, and control atelocollagen) into the livers of two living pigs. After 2 weeks, we examined tissue damage to the liver in the two pigs. RESULTS: The 75% ethanol (absolute ethanol 3.75 mL + 1% atelocollagen 1.25 mL + a very small amount of indigo carmine) was seen like blue gel, and still remained in the para-aortic tissue. Brownish areas of povidone iodine mixed with 3% atelocollagen exhibited clear, regular borders with greatly reduced infiltration into surrounding tissue compared to others. CONCLUSION: We concluded that 75% ethanol mixed with 1% atelocollagen appears optimal for EUS-CPN. Povidone iodine mixed with 3% atelocollagen may be suitable for small tumor ablation therapy.

Many postpartum women experience various poor physical conditions and are unresponsive to Western medical treatments. In such cases, treatments with Kampo medicine have so far focused on improving qi deficiency alone or both qi and blood deficiencies. This study describes the three cases of the patients for whom a favorable outcome was achieved despite a relatively poor prognosis by better understanding their status before pregnancy and their conditions during pregnancy and delivery, and by combining treatments for liver­qi stagnation with those for improving prenatal or postnatal qi deficiency.
