RÉSUMÉ

PURPOSE: The effects of water extract and distillate from the mixture of black goat meat and medicinal herb on MG-63 osteoblast proliferation and mouse bone marrow derived osteoclast formation were investigated. METHODS: Proximate composition, volatile basic nitrogen (VBN), mineral content, free amino acid composition and free fatty acid composition in black goat meat were determined. Water extract and distillate were prepared with three groups; goat meat only (BG-E, BG-D), six herbs added group (BG-E6, BG-D6), and eight herbs added group (BG-E8, BG-D8). Osteoblast proliferation, mineralization and calcium uptake activity of MG-63 cells were measured and tartrate resistant acid phosphatase activity of osteoclasts was analyzed. RESULTS: Black goat meat had remarkably low fat and high level of calcium. Glutamic acid was the most abundant amino acid. Herbs added extract groups (BG-E6 and BG-E8) showed increased MG-63 cell proliferation in a concentration dependent manner, while all the distillates did not show the effect. All extracts and distillates showed significantly increased osteoblast mineralization depending on the concentration. In particular, herb added extract, BG-E6, increased 170.3% of control and the distillate of BG-D and BG-D6 increased up to 168.5% and 159.8%, respectively. Calcium uptake activities of all water extracts showed remarkable increase of BG-E6 and BG-E8 up to 615.5% and 628.1% of control, respectively. Ditillates had no effect except BG-D6. All water extracts significantly reduced the activity of tartrate-resistant acid phosphatase (TRAP) in osteoclasts derived from mouse bone marrow. CONCLUSION: Combination of black goat meat and medicinal herb increased the MG-63 cell proliferation and effectively inhibited osteoclast differentiation in both water extracts and distillate of them, which implies that they could be used as potent functional food materials for bone health.

RÉSUMÉ

PURPOSE: The purposes of this study were to explain the phenomena of hot flashes in climacteric women by using Mexameter, Skin Thermometer, Corneometer, and Laser Doppler Perfusion Imager (LDPI) objectively and to identify the interrelation between the subjective and objective measurements of hot flashes by comparing the two as reported in retrospective questionnaires. METHODS: The participants were one hundred women (45-60 yr) who were not currently on hormone therapy, and had reached hot flash scores of 10 or higher. Hot flashes were measured in a temperature and humidity controlled room for 7 hr from 10 am to 5 pm. Hot flashes were measured subjectively and recorded via the Hot Flash Diary Report. When participants felt the hot flashes, they were measured objectively by Mexameter, Skin Thermometer, Corneometer, and LDPI. RESULTS: The frequency of hot flashes in participants ranged from 1 to 7 times. When hot flashes occurred in participants, the erythema, skin temperature, skin hydration, and blood perfusion showed statistically significant changes in all measurements. But, the subjective and objective measurements of hot flashes showed only weak correlations. CONCLUSION: Results indicate a need for future research with subjective and objective measuring instruments chosen depending variations identified for the study.

RÉSUMÉ

Apoptosis has been implicated in the pathogenesis of neurodegenerative diseases such as stroke and Alzheimer's disease. Apo-1/Fas gene is one of the mediators of apoptosis in stroke. MvaI polymorphism is the first polymorphic marker identified in the Apo-1/Fas gene promoter, which was typed by PCR and followed by MvaI digestion and gel electrophoresis. DNA isolated from peripheral blood collected from 91 stroke patients and 103 healthy blood donors was used for genotypes of GG, GA and AA by sequence specific primer PCR. MvaI polymorphism was examined based on Fas gene promotor region by restriction fragment length polymorphism (RFLP). The Fas-GG genotype was the least frequent in patients with stroke and healthy controls (P = 0.57). In normal Korean controls the MvaI polymorphism GA, AA and GG were 48.6%, 34.9% and 16.5%. In stroke patients were 56.2%, 29.6% and 14.2% respectively. And the allelic frequencies of MvaI*2 (G) allele were less frequent than MvaI*1 (A) allele in patients with stroke and healthy controls (P = 0.76). In normal Korean controls MvaI*1 (A) and MvaI*2 (G) alleles were 59.2% and 40.8%. In stroke patients were 57.6% and 42.4%, respectively. Our results, pending confirmation in a larger study, indicate that the Fas genotype may not appear to be a risk factor for stroke in Korean stroke patients.
