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.

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.

Objective: Several drugs can cause analytical interference in clinical laboratory tests.  To prevent errors in clinical judgment as a result of false data, we investigated the information available on the interference of ethical drugs in these tests.
Methods: We examined the information available by collecting and evaluating information in package insert leaflets, collecting and evaluating clinical data on three drugs (bucillamin, captopril, and epalrestat) which affect clinical laboratory test results, and conducting a questionnaire survey of healthcare workers.
Results: From the information available on package inserts, 227 drugs were identified as having the potential to interfere with the chemical reactions used in clinical laboratory tests.  However, the insert information is not sufficient for use in clinical settings because the frequency rate and causative factors of interference are not stated clearly.  The clinical survey results reveal that 40% of patients taking bucillamine and 20% of patients taking epalrestat tested false-positive for urinary ketones.  According to the questionnaire results, medical technologists were more interested than pharmacists and physicians in how drugs affect clinical laboratory tests.
Conclusion: The information currently available on the interference of drugs in clinical laboratory tests is problematical, and it is therefore necessary to collect more clinical data for the proper interpretation and evaluation of abnormal laboratory values.

AIMTo confirm the stability of exogenous genes in the generation of transgenic chickens using ejaculated chicken sperm, the deoxyribonuclease (DNase) activity was evaluated in the seminal plasma of ejaculated semen and the stability of DNA was examined by adding lipofection reagents.

METHODSA PCR fragment (249 bp) of pEGFPN-1 vector was used as the DNA substrate and was incubated with the seminal plasma at 40 degree C for 30 min. Then, the whole reaction solution was subjected to agarose gel electrophoresis and the DNA size was evaluated under UV light.

RESULTSThe DNA substrate was completely diminished after incubation with seminal plasma. However, the substrate was intact after incubation with heat-treated seminal plasma or incubation with seminal plasma in the presence of 0.5 mmol/L approximately 5 mmol/L EDTA. The substrate was stabilized in the seminal plasma by the addition of commercially available lipofection reagents.

CONCLUSIONThe DNase activity is present in the seminal plasma of ejaculated chicken semen. However, DNA is stable in the liposomal-DNA complex.

Objective: The purpose of this study is to compare the clinical efficacy between original drugs and generic products.  Candidate drugs included two types of hydroxymethylglutaryl-CoA (HMG-CoA) reductase inhibitors, simvastatin and pravastatin, because of their importance at reducing the health expenditure for hyperlipidemia.
Design: We retrospectively evaluated the efficacy (total cholesterol, triglyceride, low-density lipoprotein and high-density lipoprotein levels), safety (biochemical parameters), and medication adherence based on patient data.  We set the follow-up period at 6 months before and after substitution.  Data were analyzed by paired-sample t-tests (statistical significance level of 0.05).
Methods: The subjects included in this study were ambulatory patients visiting Nakajima Hospital for dyslipidemia treatment.  Selected patients included those taking both the original drug and the generic product; i.e., patients who had substituted the original drug Lipovas® for the generic product Simvastatin OHARA, or those who had substituted the original drug Mevalotin® for the generic drug Pravatin®.
Results: A total of 118 patients in the simvastatin study and 43 patients in the pravastatin study were candidates for the present study.  We found that there were no significant differences before and after substitution.  Even though there were differences in some of the biochemical parameters, the range remained within normal levels.  With regard to medication adherence, we found no significant differences.
Conclusion: In this study, we found no significant differences before and after substituting medications with generic drugs.  Additionally, we found no subjective symptom changes after substitution.  To develop clinical information on generic products and to store such information, it is important that pharmaceutical products be used appropriately.

When adipose-derived stem cells (ASCs) are retrieved from the stromal vascular portion of adipose tissue, a large amount of mature adipocytes are often discarded. However, by modified ceiling culture technique based on their buoyancy, mature adipocytes can be easily isolated from the adipose cell suspension and dedifferentiated into lipid-free fibroblast-like cells, named dedifferentiated fat (DFAT) cells. DFAT cells re-establish active proliferation ability and undertake multipotent capacities. Compared with ASCs and other adult stem cells, DFAT cells showed unique advantages in their abundance, isolation and homogeneity. In this concise review, the establishment and culture methods of DFAT cells are introduced and the current profiles of their cellular nature are summarized. Under proper induction culture in vitro or environment in vivo, DFAT cells could demonstrate adipogenic, osteogenic, chondrogenic and myogenic potentials. In angiogenic conditions, DFAT cells could exhibit perivascular characteristics and elicit neovascularization. Our preliminary findings also suggested the pericyte phenotype underlying such cell lineage, which supported a novel interpretation about the common origin of mesenchymal stem cells and tissue-specific stem cells within blood vessel walls. Current research on DFAT cells indicated that this alternative source of adult multipotent cells has great potential in tissue engineering and regenerative medicine.
