PURPOSE: In spite of the development of asthma management guidelines, there are discrepancies between the guidelines and real management. We surveyed the insights and the real management of asthma to assess the current status of its management in Korea. METHODS: The objects of the survey were 266 parents with asthmatic children, who attended an educational lecture by the Korean World Asthma Day Project Office (KWADPO). Face to face interviews with questionnaires of 11 questions about understanding of asthma maintenance therapy, actual conditions of taking medicine and the impact of asthma on the family life were undertaken. RESULTS: The Median age of the patients was 5.2 years old and their parents' age ranged from those in their twenties to those in their forties. The number of the patients actually taking asthma maintenance medicine (40.6 percent) was a little bit lower than the level of awareness (53.0 percent). As a controller, patients are using short-acting beta2 inhalers (35.3 percent), steroid inhalers (including combination inhaler) (31.6 percent), leukotriene receptor antagonists (24.8 percent), antihistamines (25.6 percent), theophylline (2.3 percent), etc. Regular visits to hospital or clinic were done in 53.0 percent of the patients. As a controllers, oral medications (69.2 percent) was preferred to inhalers (18.0 percent) due to better compliance and easier dosage adjustment. CONCLUSION: According to the survey, asthma had negative effects on the life quality of patients and their families. Remarkable discrepancies were noticed between the guidelines and the real-world status of taking medicine in asthmatic children. It is necessary to have patients participate actively in making asthma management plans to raise their efficacy.

OBJECTIVES: Osteoporosis is a disease of bones that is thought to result from an imbalance between bone resorption and bone formation. Although osteoporosis itself has no symptoms, osteoporosis caused by osteoclasts leads to an increased risk of fracture. Here we examined the effects of cornus officinalis on receptor activator of nuclear factor-kappaB ligand (RANKL)-mediated osteoclast differentiation. METHODS: We evaluated the effects of cornus officinalis on RANKL-induced osteoclast differentiation from bone marrow-derived macrophages (BMMs) and performed a cytotoxicity assay, reverse transcriptase-polymerase chain reaction (RT-PCR), and Western blot analysis. RESULTS: Cornus officinalis significantly inhibits RANKL-mediated osteoclast differentiation in a dose-dependent manner, but without cytotoxicity against BMMs. The mRNA expression of tartrate-resistant acid phosphatase (TRAP), osteoclast-associated receptor (OSCAR), c-Fos, and nuclear factor of activated T cells cytoplasmic 1 (NFATc1) in BMMs treated with RANKL was considerably inhibited by cornus officinalis treatment. Also, cornus officinalis inhibits the protein expression of c-Fos and NFATc1. Cornus officinalis greatly inhibits RANKL-induced phosphorylation of p38 and c-JUN N-terminal kinase (JNK). Also, cornus officinalis significantly suppresses RANKL-induced degradation of I-kappaB. CONCLUSIONS: Taken together, our results suggest that cornus officinalis may be a useful the treatment of osteoporosis.
