[Granulocyte-colony stimulating factor-producing multiple myeloma presenting with neutrophilia].

A 71-year-old woman complained of nausea and anorexia. Laboratory tests revealed significant neutrophilia and immunoglobulin A-kappa type M proteinemia, as well as increased plasma cells on bone marrow examination. Furthermore, the serum granulocyte-colony stimulating factor (G-CSF) concentration was high at 160 pg/ml, and the colony stimulating factor 3 receptor (CSF3R)-T618I mutation was negative.

Genetic analysis of Curcuma species from Asia based on intron regions of genes encoding diketide-CoA synthase and curcumin synthase.

Intron length polymorphism (ILP) markers in genes encoding diketide-CoA synthase (DCS) and curcumin synthase (CURS) showed high identification rates in 13 Curcuma species from Asia. However, the sequences of the intron regions have not yet been analyzed. To elucidate the sequence differences in intron regions of the DCS and CURS genes and to search for specific sequences suitable for the identification of Curcuma species, a large number of sequences were determined through subcloning coupled with sequencing analysis of six Curcuma plant specimens belonging to five species that showed distinct ILP patterns.

Discrimination of Curcuma species from Asia using intron length polymorphism markers in genes encoding diketide-CoA synthase and curcumin synthase.

Recently, Curcuma rhizome-related foods with claimed health benefits have been used worldwide; however, correct identification and quality assessment have not been conducted. Due to the wide distribution and morphological similarities of Curcuma species, the classification of some species is debated and nomenclature is inconsistent among countries. In this study, to elucidate specific molecular markers of medicinally used Curcuma species in Asia, and to solve the confusion on the reported botanical origin of crude drugs, molecular analysis based on the intron length polymorphism (ILP) in genes encoding diketide-CoA synthase and curcumin synthase and the trnK intron sequences was performed using 59 plant specimens and 42 crude drug samples from 13 Curcuma species, obtained from Asian countries.

Characterization of metabolites in Saposhnikovia divaricata root from Mongolia.

Saposhnikoviae Radix (SR), derived from the dried root and rhizome of Saposhnikovia divaricata, is a popular crude drug used in traditional Chinese and Japanese medicine. To evaluate the metabolites of S. divaricata roots from Mongolia and to investigate their geographical variation, we developed the HPLC method, determined the contents of 9 chromones and 4 coumarins, and conducted multivariate statistical analysis.

Evaluation of the safety and efficacy of Glycyrrhiza uralensis root extracts produced using artificial hydroponic and artificial hydroponic-field hybrid cultivation systems III: anti-allergic effects of hot water extracts on IgE-mediated immediate hypersensitivity in mice.

To evaluate the safety and efficacy of Glycyrrhiza uralensis root extracts produced using artificial hydroponic and artificial hydroponic-field hybrid cultivation systems, we investigated anti-allergic action in mice using IgE-mediated immediate hypersensitivity. Hot water extracts obtained from the roots of Glycyrrhiza uralensis cultivated using two systems were orally administered at a dose of 100 mg/kg as glycyrrhizin (GL) and compared with the commercial crude drug, Glycyrrhizae Radix. Both the artificial hydroponic and artificial hydroponic-field hybrid cultivated root extracts showed anti-allergic effects on IgE-mediated immediate hypersensitivity in mice, as did the commercial crude drugs.

Metabolomic profiling of Saposhnikoviae Radix from Mongolia by LC-IT-TOF-MS/MS and multivariate statistical analysis.

Saposhnikoviae Radix (SR) is a commonly used crude drug that is obtained from the root and rhizome of Saposhnikovia divaricata which is distributed throughout China, Korea, Mongolia, and Russia. To evaluate the quality of Mongolian S. divaricata, metabolomic profiling of 43 plant specimens from different regions of Mongolia, as well as 8 SR samples and 2 plant specimens from China, were conducted by liquid chromatography-ion-trap-time-of-flight-mass spectrometer (LC-IT-TOF-MS).

Evaluation of the safety and efficacy of Glycyrrhiza uralensis root extracts produced using artificial hydroponic-field hybrid cultivation systems II: comparison of serum concentration of glycyrrhetinic acid serum concentration in mice.

To evaluate the safety and efficacy of Glycyrrhiza uralensis root produced using artificial hydroponic and artificial hydroponic-field hybrid cultivation systems, we investigated the pharmacokinetics of a major metabolite of glycyrrhizin (GL), glycyrrhetinic acid (GA). Hot water extracts obtained from the roots of the artificial hydroponic-field hybrid cultivated Glycyrrhiza uralensis were orally administered at a dose of 100 mg/kg as GL in mice and, compared with a commercial crude drug, Glycyrrhizae Radix. The temporal changes in serum GA concentration was found to depend on the GL concentration of the hot-water extracts.

Heme oxygenase-1 prevents glucocorticoid and hypoxia-induced apoptosis and necrosis of osteocyte-like cells.

Glucocorticoids and hypoxia is considered to promote osteocyte apoptosis and necrosis, which are observed in glucocorticoid-associated osteonecrosis and osteoporosis. Heme oxygenase-1 (HO-1) induced by hemin is reported to have cytoprotective effects in ischemic diseases. The objective of this study was to evaluate the effect of HO-1 on osteocyte death caused by glucocorticoids and hypoxia.

Evaluation of femoral perfusion using dynamic contrast-enhanced MRI after simultaneous initiation of electrical stimulation and steroid treatment in an osteonecrosis model.

Restructuring the Ikeda City school urinary screening system: report of a screening survey.

Background: Annual urinary screening is conducted at municipal kindergartens, elementary schools, and junior high schools in Ikeda City, Osaka, Japan (Ikeda City School System), and the results are reviewed by a general physician, but standards for when to recommend specialist referral have not been clear.

Methods: In all children attending the Ikeda City School System in 2012, dipstick urinalysis of a first-morning urine specimen was recommended once or twice, and if a second urinalysis showed proteinuria (≥1+), the urinary protein/creatinine ratio was measured. If this showed ≥0.
