  • In order to study tile effects of moxibustion on renal failure induced by $HgCl_2$ in rats aminal experiments were carry out. The moxibustion was treat into Sin-soo locus(VII23), We-soo locus(VII21) and Sin-soo + We-soo loci these loci were correspond to human body. Experimental group were divided into 4 groups : lontrol group, moxibustion groups treat on Sin-Soo and We-Soo, Sin-Soo + We-Soo group. The obtained results were as follows : 1. The concentration of serum sodium were inreased in all the groups, compared with those of the control group. Sin-Soo, We-Soo, Sin-Soo + We-Soo loci showed increased on the 1st and 3rd days. All three experimental groups showed a significant increased on 3rd day. 2. The concentration of serum potassium were decreased in all the group, compared with those of the control group. Sin-Soo, We-Soo showed a significant decrease on 3rd day. Sin-Soo + We-Soo showed a little decrease but do not significant decrease. 3. The levels of serum total protein were increased in all the group, compare with those of the control group. Sin-Soo, We-Soo show a significant increased or 3rd day. Sin-Soo + We-Soo do not showed a significant increased. 4. The levels of serum albumin were decreased in all the groups, compared with those of the control group. Sin-Soo, Sin-Soo + We-Soo showed a significant decrease on 3rd day. We-Soo does not showed a significant decrease. 5. The concentration of serum blood urea nitrogen were decreased in all the groups, compared with those of the control group. Sin-Soo, We-Soo, Sin-Soo + We-Soo showed a significant decrease on 3rd day. 6. The levels of serum alkaline phosphatase were decreased in all the group, compared with those of the control groups. Sin-Soo, We-Soo showed a significant decrease on 3rd day Sin-Soo + We-Soo not a significant decrease. In conclusion, the result of this study seemed to effect on the treatment for renal failure induced by $HgCl_2$.

  • Peroxynitrite is a potent neurotoxic molecule produced from a reaction between NO and super-oxide and induces NO-mediated inflammation under neuropathological conditions. Previously, we reported that glucose deprivation induced ATP depletion and cell death in immunostimulated astrocytes, which was mainly due to peroxynitrite. In this study, the role of MAPKs (ERK1/2, p38MAPK, and JNK/SAPK) signal pathway in the SIN-1/glucose deprivation-induced death of astrocytes was examined. A combined treatment with glucose deprivation and $50 {\mu}M$ SIN-1, an endogenous peroxynitrite generator, rapidly and markedly increased the death in rat primary astrocytes. Also, SIN-1/glucose deprivation resulted in the activation of MAPKs, which was significantly blocked by the treatment with $20{\mu}M$ MAPKs inhibitors (ERK1/2, PD98059; p38MAPK, SB203580; JNK/SAPK, SP600125). Interestingly, SIN-1/glucose deprivation caused the loss of intracellular ATP level, which was significantly reversed by MAPKs inhibitors. These results suggest that the activation of MAPKs plays an important role in SIN-1/glucose deprivation-induced cell death by regulating the intracellular ATP level.

  • The purpose of this paper is to research the estimations of the indoor natural temperature in a case of the earth sheltered space and the 1st basement room in comparison with a conventional housing. The result of this study can be summerized as follows: The natural temperature of the earth sheltered house Summer : $${\theta}es=27.0+1.65sin(2{\pi}/24{\cdot}T-1.34)$$ Winter : $${\theta}ew=11.5+1.15sin(2{\pi}/24{\cdot}T-1.61)$$ The natural temperature of the 1st basement space Summer : $${\theta}us=25.5+1.00sin(2{\pi}/24{\cdot}T-1.72)$$ Winter : $${\theta}uw=13.9+1.10sin(2{\pi}/24{\cdot}T-2.29)$$ From the results of the stated above, we can calculate the cooling and heating load in the earth sheltered house and the underground space exactly and easily at Taejeon City.

Pharmacognostical Studies on the Korean Folk Medicine(1)-On the 'Sin Seong Cho'- (한국민간약(韓國民間藥)의 생약학적(生藥學的) 연구(硏究)(제1보)(第1報)-"신성초(神聖草)"에 관해서-)

  • Korean folk medicine 'Sin Seong Cho' (神聖草)has been used to cure common cold, neuralgia and cancer of the stomach in Korea. The botanical origin of the crude drug has been no pharmacognostical confirmation on it. To clarify the botanical origin of 'Sin Seong Cho', the morphological and anatomical characteristics of the rhizomes of Davallia mariesii Moore and Neocheiropteris ensata (Thunb.) Ching growing in Korea were examined. As the result, it was made clear that 'Sin Seong Cho' from Korea was derived from the rhizomes of Davallia mariesii, rarely from the rhizomes of Neocheiropteris ensata.

  • This study was designed to clarify the mechanism of the inhibitory action of a nitric oxide (NO) donor, 3-morpholino-sydnonimine (SIN-1), on contraction, cytosolic $Ca^{2+}$ level $([Ca^{2+}]_i)$ and ionic currents in guinea-pig ileum. SIN-1 $(0.01{\sim}100\;{\mu}M)$ inhibited 25 mM KCl- or histamine $(10\;{\mu}M)-induced$ contraction in a concentration-dependent manner. SIN-1 reduced both the 25 mM KCl- and the histamine-stimulated increases in muscle tension in parallel with decreased $[Ca^{2+}]_i.$ Using the patch clamp technique with a holding potential of -60 mV, SIN-1 $(10\;{\mu}M)$ decreased peak Ba currents $(I_{Ba})$ by $30.9{\pm}5.4%$ (n=6) when voltage was stepped from -60 mV to +10 mV and this effect was blocked by ODQ $(1\;{\mu}M),$ a soluble guanylyl cyclase inhibitor. Cu/Zn SOD (100 U/ml), the free radical scavenger, had little effect on basal $I_{Ba},$ and SIN-1 $(10\;{\mu}M)$ inhibited peak $I_{Ba}$ by $32.4{\pm}5.8%$ (n=5) in the presence of Cu/Zn SOD. In a cell clamped at a holding-potential of -40 mV, application of $10\;{\mu}M$ histamine induced an inward current. The histamine-induced inward current was markedly and reversibly inhibited by $10\;{\mu}M$ SIN-1, and this effect was abolished by ODQ $(1\;{\mu}M).$ In addition, SIN-1 markedly increased the depolarization-activated outward $K^+$ currents in the all potential ranges. We concluded that SIN-1 inhibits smooth muscle contraction mainly by decreasing $[Ca^{2+}]_i$ resulted from the inhibition of L-type $Ca^{2+}$ channels and the inhibition of nonselective cation currents and/or by the activation of $K^+$ currents via a cGMP-dependent pathway.

  • Two genes, SinIFS1 and SinIFS2 from Korean soybean cultivar, Sinpaldalkong known as one of isoflavonerich cultivars, were cloned with PCR and degenerate primers. The sequences of two genes were analyzed with previously reported IFS genes of leguminous plants and their expression pattern in various environmental conditions was surveyed. The genomic clone of SinIFS1 contained 1,828bp nucleotides and encoded a polypeptide of 521 amino acids, and 1912bp nucleotides and a polypeptide of 521 amino acids for SinIFS2. Both genes included several conserved motifs, oxygen binding and activation (A/G-G-X-E/D-T-T/S), ERR triad (E...R....R), and heme binding (F-X-X-G-X-R-X-C-X-G) domain, which are typical in any member of cytochrome P45O superfamily. Very high sequence homology (>98%) was observed in the comparison with other IFSs of legumes. In the northern blot analysis to check the expression and increase of SinIFS1 to various environmental renditions (low temperature, light, dark, UV, and fungal elicitor), the most significant induction, more than 6 times of transcript level compared to the dark treatment as a control, was observed from the fungal elicitor treatment. The next up-regulated expression was from UV treatment (4${\times}$), low temperature and light conditions.

  • The present study was undertaken to test the hypothesis that dietary antioxidants protect DNA damage induced by peroxynitrite, a potent physiological inorganic toxin. The present study showed that dietary antioxidants such as (-)-epigallocatechin gallate, quercerin, rutin, resveratrol, and ursolic acid inhibit single strand breaks in supercoiled plasmid DNA induced by 3-morpholinosydnomine N-ethylcarbamide (SIN-1), a generator of peroxynitrite through the reaction between nitric oxide and superoxide anion. The formation of 8-hydroxy-2'-deoxyguanosine (8-OH-dG) in calf thymus DNA by SIN-1 was also inhibited by dietary antioxidants. When U937 cells were incubated with 1 mM SIN-1 bolus, a significant increase of 8-OH-dG level was observed. However, oxidative DNA damage was significantly lower in the cells pre-treated with dietary antioxidants when cells were exposed to SIN-1.
