Objective: To clarify the reason why the target levels of low-density lipoprotein (LDL)-cholesterol are hardly attained.
Methods: The questionnaire was performed for 237 general practitioners on prescription of HMG-CoA reductase inhibitors (statins), just after the publication of “Japan Atherosclerosis Society (JAS) Guidelines for Prevention of Atherosclerotic Cardiovascular Diseases 2007”.
Results: The responses could be summarized as 1) almost all doctors recognized the significance of target levels of LDL-cholesterol; 2) however, general physicians have such a recognition to a lesser extent, compared with cardiologists; 3) when prescribing statins, 66.2% of them had concerns about drug-drug interactions; 4) as the adverse events with statins, they listed creatine kinase (CK) elevations (86.5%), hepatic dysfunction (74.3%) and myalgias/rhabdomyolysis (70.9%); 5) in contrast, less than 20% of them listed the fulminant hepatic failure, gastrointestinal symptoms and fluctuation of blood glucose levels; 6) the threshold value of CK to discontinue statins was 500 IU/L in 44.4% and 200-300 IU/L in 39.6%; and 7) 78.5% of them believed that statins have the pleiotropic ability such a anti-inflammatory effect clinically, in addition to lipid-lowering.
Conclusions: It is important to serve the drug information about the safety of statins to the general practitioners for the management of hyperlipidemia, based on original articles.

Hot water extract of adlay (Coix lachryma-jobi L. var. ma-yuen Stapf) seed, commonly called Yokuinin, has been used as herbal medicine for treating verruca vulgaris, et al. Although there have been a number of studies on the usefulness of Yokuinin, the pharmacological assessment of its husk, pellicle, and astringent skin remains unclear. In this line, we evaluated the effect of methanol extract from all parts of adlay grain (seed, husk, pellicle, astringent skin) on cancer cells and identified its useful chemical components. Results revealed that a fraction of the extract have weak growth-suppressing activity on human cervical cancer cell line (HeLa cell). In particular, 5,7-dihydroxychromone and coixol were isolated and identified from the active fraction. This indicates the possible cancer chemopreventive efficacy of methanol extract from adlay. Moreover, further tests are needed to determine the role of 5,7-dihydroxychromone.

Oxidative stress is considered to contribute to degenerative disease. The urinary excretion of the DNA repair product 8-hydroxy-2′-deoxyguanosine (8-OHdG) is proposed as a noninvasive biomarker of current oxidative stress in vivo. We investigated the effect of an antioxidant mixture on urinary 8-OHdG excretions in 12 otherwise healthy smokers. During the intervention period for 2 weeks, subjects consumed four capsules of PICACE^® (Pycnogenol^® 15 mg/capsule, Vitamin E; 56.1 mg/capsule, Squalene; 138.9 mg/capsule) per day. On days 0 (pre-internal use), 3, 7, 14, and 44, morning urine samples were collected. The urinary 8-OHdG was measured using high-performance liquid chromatography (HPLC). The urinary 8-OHdG level on day 3 was significantly reduced compared to day 0. The level of 8-OHdG after a washout period for PICACE^® (days 44) returned to day 0 baseline. These preliminary data suggest that PICACE^® supplements can protect smokers from oxidative stress and possibly reduce disease risk caused by free radicals associated with smoking.
