Objective : This experimental study was designed to determine the effects of BPT on obesity in vivo and in vitro. Methods : in vitro, BPTn extracts of various concentration(50, 100, 200 ${\mu}g/m{\ell}$) were added in 3T3-L1 cell. Adipocyte differentiation was measured by Oil Red O staining and Morphological examination. The expression of $C/EBP{\alpha}$ and $PPAR{\gamma}$ receptor was measured by western blot assay and RT-PCR in vivo, Rats were orally administered BPT daily for consecutive four weeks before poloxamer-407 induced hyperlipidemic state. The rats were sacrificed 24 hrs later for poloxamer-407 treated and then serum triglyceride, total cholesterol were measured ; Rats were orally administered BPT daily for consecutive four weeks before triton WR-1339 induced hyperlipidemic state. The rats were sacrificed 40 hrs later for triton WR-1339 treated and then serum triglyceride, total cholesterol were measured ; Rats with obesity were induced by the high fat-diet for six weeks and then serum triglyceride, total cholesterol, LDL-cholesterol, triglyceride, HDL-cholesterol, hydroxy radical, superoxide dismuatse activity were measured. Results : In vitro, The 3T3-L1 cells' differentiation was significantly decreased by BPT. The expression of $C/EBP{\alpha}$ and $C/EBP{\beta}$ was decreased by BPT. In vivo, BPT significantly reduced serum triglyceride, total cholesterol contents in poloxamer-407 treated rat. BPT significantly reduced serum triglyceride contents in Triton WR-1339 treated rat. Total cholesterol also reduced but did not show a significant change. BPT significantly reduced body weight gain of rat and adipose tissue mass of rats and serum triglyceride, LDL-cholesterol contents and significantly increased HDL-cholesterol, HTR(HDL-cholesterol/Total-cholesterol) in rats with obesity induced by the high fat-diet. BPT reduced blood lipid peroxide, hydroxy radical and increased superoxide dismuatse(SOD) activity.
$Na_2SO_4$가 시멘트-플라이애쉬 페이스트 및 콘크리트 강도에 미치는 영향

플라이애쉬 대체량에 따른 변화, 양생방법이 미치는 영향 그리고 조기강도를 높이기 위해 첨가된 화학 혼화제가 시멘트-플라이애쉬 페이스트의 특징 및 콘크리트 강도에 미치는 영향을 알아보았다. 시멘트-플라이애쉬 페이스트의 압축강도는 시멘트로만 만들어진 페이스트보다 낮았으며, 플라이애쉬의 대체량이 증가할수록 강도차이가 증가하였다. 그러나 증기양생시 시멘트-플라이애쉬 페이스트는 수중양생시보다 압축강도가 증가하였으며, 특히 조기강도가 크게 향상되었다. 조기강도 증진을 목적으로 혼입한 활성화제($Na_2SO_4$)의 첨가는 시멘트-플라이애쉬 페이스트 조기강도를 증진시켰으며, 또한 $Na_2SO_4$와 플라이애쉬를 30% 함유한 플라이애쉬 콘크리트의 강도도 월등히 향상되었다. It was investigated to evaluate the characteristics of cement-flyash paste which was affected the replacement level, curing method and chemical admixtures. The strength of cement-flyash paste was lower than that of cement paste only and the differences increased with increasing the replacement level. However, in steam curing, the strength of cement-flyash pastes was improved and specially, the early strength was effectively increased. The inclusion of $Na_2SO_4$ increased the early strength of cement-flyash paste. In addition, the strength of concrete including 30% of fly ash and $Na_2SO_4$ has improved and obtained the highest strength compared to other concrete mixes.

Objective : This experimental study was performed to examine the anti-allergic infiammatory effects of Mori Folium. Method : Macrophage 264.7 cells were pretreated for 1hour with Sangyup. After pretreatment, macrophage were incubated with lipopolysaccharide(LPS) $100ng/m{\ell}$ 12h and media collected and $TNF-{\alpha}$, $IL-1{\beta}$, IL-6, IL-10 concentrations in supernatants were measured each by Enzyme linked immuno-sorbent assay. Sangyup were used $1mg/m{\ell}$, $500{\mu}g/m{\ell}$, $250{\mu}g/m{\ell}$, $100{\mu}g/m{\ell}$, $50{\mu}g/m{\ell}$. Hydrocortisones were used $10^{-4}M,\;10^{-5}M,\;10^{-6}M,\;10^{-6}M,\;10^{-6}M$. Results : Macrophage 264.7 cells were pretreated with Hydrocortisones and Sangyup. After pretreatment, macrophage were incubated with lipopolysaccharide(LPS). To investigate the anti-inflammatory effect of Sangyup, we measured the amount of cytokines, and the results are as follows; 1. Mori Folium. showed statistically significant inhibitory effect on antiinflammation in $TNF-{\alpha}(p<0.02)$ in all five concentrations compared with the (-)controls treated with LPS. Mori Folium showed inhibitory effect on antiinflammation in $TNF-{\alpha}$ in similarpattern in all five concentrations compared with the (+)control pretreated with hydrocortisone. 2. Mori Folium. showed statistically significant inhibitory effect on antiinflammation in IL-6(p<0.01) in all five concentrations compared the (-)controls treated with LPS. Mori Folium. showed inhibitory effect on antiinflammation IL-6 similar pattern in all five concentrations compared with the (+)control pretreated with hydrocortisone. 3. Experimental Group pretreated with Mori Folium. showed statistically significant difference of antiinflammation in $IL-1{\beta}$ in concentrations of $50{\mu}g/m{\ell}(p<0.01)$, $250{\mu}g/m{\ell}(p<0.05)$ compared with the (-)control treated with LPS. Experimental Group pretreated with Mori Folium. showed increased level of $IL-1{\beta}$ in all concentrations compared the (+)control treated with hydrocortisone. 4. Experimental Group pretreated with Mori Folium. did not show statistically significant effect on IL-10 compared with the (-)control. Conclusion : By the findings of this experiment, Mori Folium is observed to have antiallergic and antiinflammation effect.

Cerebrovascular disease in children is more common than once recognized and the etiology and prognosis of the disease in children are quite different from those of adults. In Korea, the most common cause of stroke is moyamoya disease in ischemic stroke, arteriovenous malformation in hemorrhagic stroke. We experienced two cases of ischemic stroke in childhood whose symptoms are similar to that of adults. They had cerebrovascular malformation(narrowing of ICA, MCA, basilar artery). we treated them with herb medicine, acupuncture treatment, laser acupuncture treatment and physical treatment. After treatment, they recovered from the stroke symptoms, but the primary cause of stroke was not eliminated, so it is thought that more follow up is needed. We report that we had good effects of oriental medical treatment on two case of cerebral infarction in children.
