Objective : The purpose of this study is assistant to medical treatment for patient who suffers from headache, by immediate effects of GB43, LI1. Methods : The degree of pain was measured by visual analogue scale(VAS) after GB43, LI1 needling. Results : 15 cases of immediate effects of GB43, LI1 for headache have some common points. 1. The pain of headache was induced by internal cause. 2. The pain of headache was in chronic process. 3. The patients has chronic functional dyspepsia and psychological factors. Conclusion : We can expect immediate effects by GB43, LI1 needling for headache, which have some common points.

Objectives : The purpose of this study is to research the effects of acupuncturing $BL_{67}$ and $LI_1$ and determine the mechanism of action of acupuncturing $BL_{67}$ and $LI_1$ by measuring the changes of regional cerebral blood flow(rCBF) and mean arterial blood pressure(MABP) in normal rats and ischemic rats. Method : This study researched the effects of acupuncturing $BL_{67}$ and $LI_1$ on the change of rCBF and MABP. To determine the mechanism of action of acupuncturing $BL_{67}$ and $LI_1$, pretreatment with indomethacine and methylene blue was done. Result : 1. Acupuncturing $BL_{67}$ and $LI_1$ significantly increased rCBF and acupuncturing $BL_{67}$ and $LI_1$ induced increase of rCBF was significantly inhibited by pretreatment with indomethacin(1 mg/kg, i.p.), an inhibitor of cyclooxygenase, and methylene blue(10 ${\mu}g$/kg, i.p.), an inhibitor of guanylate cyclase. 2. Acupuncturing $BL_{67}$ and $LI_1$ decreased MABP and there was no significantly change of decrease of MABP on acupuncturing $BL_{67}$ and $LI_1$ by pretreatment with indomethacin and methylene blue. 3. These result suggested that acupuncturing $BL_{67}$ and $LI_1$ might significantly increase rCBF by dilating arterial diameter and mechanism of acupuncturing $BL_{67}$ and $LI_1$ might be mediated by cyclooxygenase and guanylate cyclase. 4. The rCBF was significantly and stably increased by acupuncturing $BL_{67}$ and $LI_1$ during the period of cerebral reperfusion in cerebral ischemic rats, which contrasted with the rapid and marked increase in the control group. Pretreatment with methylene blue significantly decreased rCBF by acupuncturing $BL_{67}$ and $LI_1$ during the period of ischemic state, increased rCBF during the period of cerebral reperfusion. These results suggested that the mechanism of acupuncturing $BL_{67}$ and $LI_1$ might be mediated by guanylate cyclase. Conclusion : Acupuncturing $BL_{67}$ and $LI_1$ can increase rCBF in normal state, and improve stability of rCBF in ischemic state. In addition, we suggested that mechanisms related with acupuncturing $BL_{67}$ and $LI_1$ was more involved in the guanylate cyclase pathway.

The effect of particle size of silicate fertilizer, crushed slag from the steel industry, on the behavior of silicate in soil was investigated through laboratory experiments. The silicate fertilizer was sieved to obtain three fractions of particles, coarser than 10 mesh 20-35 mesh, and finer than 100 mesh. Silicate concentration of the extract obtained by shaking 20 mg of particles, coarser than 10 mesh, 20-35 mesh, and finer than 100 mesh, in 50 ml of distilled water for 4 hours was 0.3, 1.0, and 3.2 ppm respectively. As shaking the mixture of the silicate fertilizer and soil proceeded, silicate concentration of the extract increased, and this increase after 4 hour shaking was attributed mainly to dissolution of soil silicate. When the mixture of soil and the silicate fertilizer was incubated under submerged condition, silicate concentration of the solution decreased for the first 2-4 weeks, thereafter increased with incubation time. During this incubation period, silicate concentration of the solution changed inversely with pH of the solution. After 6-10 weeks, however, both silicate concentration and pH of the solution increased with incubation time. Silicate concentration of the effluent from the 14.5 cm soil column of which top 4.5 cm was packed with the mixture of 30 g of soil and 30 mg of the silicate fertilizer reached maximum at 0.94 pore volumes for the particles of 20-35 mesh and 1.03 pore volumes for the particles finer than 100 mesh, whereas the effluent concentration reached maximum at 0.88 pore volumes for the soil column without the silicate fertilizer treatment. Soil analysis made after water percolation revealed that 1.5 pore volumes of water could leach down large amount of the water soluble silicate but not the sodium acetate extractable silicate, from top 3-6 cm soil layer.
