Lung cancer is one of the common malignant tumors in the world. It occurs more increasingly due to the serious air pollution, heavy smoking, expoure to ionized radiation, pollution with heavy metal, and owing to well advanced diagnostic skill, etc. Also lung cancer has the limitation of medical care because metastasis is already shown up in more than half cases when it is first detected through medical examination. Although it is treated with chemoradiation, the rate of deaths from lung cancer is high as well, because blood has a lot of toxicity which give side effects. So it has a low rate of cure. So, the ways of various treatment is being researched to raise the rate of care and decrease the side effects recently, and one of the results is inducing apoptosis which makes use of molecularbiologic diagnosis of lung cancer's cell and using oriental medicine drugs. The purpose of this study is whether apoptosis would happen on the human lung carcinoma cell by treated with Junglyeokdaejosape-tang, Junglyeok-tang Junglyeokdaejosape-tang and Junglyeok-tang has been prescribed for cough, chest pain, and many other similar cases. Cough and chest pain is shown in early lung cancer. That is why we used these prescriptions. Apoptosis happend on the human lung carcinoma A549 cells treated with Jeongiyeokdaejosapye-tang, Jeonglyeok-tang. The concentration-dependent inhibition of cell viability was observed and apoptosis was confirmed by DNA fragmentation. Bcl-2 and COX-2 mRNA expression decreased, but Bax mRNA expression increased, so it was identified with the case of indomethacin known to enhance apoptotic DNA fragmentation. Also expression of the p21, p53, cyclin E, cyclin D1, cytochrome c, caspase-3, and caspase-9 protein increased and the activity of caspase-3 increased, as well. Last, fragmentation of the PARP was shown. The previous and present results indicated that apoptosis of A549 cells by above-mentioned drugs is associated with the blockage of G1/S progression.

Radix Asteris has been used in Korea for many centuries as a treatment for respiratory disease. The effect of Radix Asteris on tracheal smooth muscle is not known. The purpose of the present study is to determine the effect of Radix Asteris on histamine induced tracheal smooth muscle contraction in rats and guinea pigs. Guinea pig(500g, male) and Sprague Dawley rats (250g, male) were killed by $CO_2$ exposure and a segment (8-10mm) of the thoracic trachea from each rat and guinea pig was cut into equal segments and mounted 'in pairs' in a tissue bath. Contractile force was measured with force displacement transducers under 0.5g loading tension. The dose of histamine (His) which evoked 50% of maximal response ($ED_{50}$) was obtained from cumulative dose response curves for histamine $(10^{-7}{\sim}10^{-4}M)$. Contractions evoked by His ($ED_{50}$) were inhibited significantly by Radix Asteris. In guinea pig tracheal smooth muscle, the mean percent inhibition of histamine induced contraction was 120.5% (p<0.01) after $100{\mu}l/ml$ Radix Asteris. In rat tracheal smooth muscle, the mean percent inhibition of histamine induced contraction was 135.4% (p<0.01) after $100{\mu}l/ml$ Radix Asteris. Propranolol $(10^{-7}M)$ slightly but significantly attenuated the inhibitory effects of Radix Asteris. Following treatment with propranolol, the mean percent inhibition caused by $100{\mu}l/ml$ Radix Asteris fell to 44.6% in guinea pig induced by histamine contraction and by $100{\mu}l/ml$ Radix Asteris fell to 18.7% (p<0.05) in rat induced by histamine contraction. Indomethacin and methylene blue$(10^{-7}M)$ did not significantly alter the inhibitory effect of Radix Asteris. These results indicate that Radix Asteris can relax histamine induced contraction of guinea pig and rat tracheal smooth muscle, and that this inhibition involves sympathetic effects.

Purpose: To provide the information of efficacy for herbal formulas of high frequency, it was evaluated the anti-inflammatory effect. In many studies, plantderived anti-inflammatory efficacies have been investigated for their potential inhibitory effects on lipopolysaccharide (LPS)-stimulated macrophages. This study was performed to examine the anti-inflammatory effects of herbal formulas of high frequency on LPS-stimulated RAW 264.7 cells. Methods: Anti-inflammatory activity was investigated in 25 herbal formula extracts in vitro and in vivo. To investigate the anti-inflammatory effect in vitro model, using LPS-stimulated macrophages, RAW 264.7 cell line. The productions of nitric oxide(NO), prostaglandin(PG)$E_2$, interleukin(IL)-6 and tumor necrosis factor(TNF)-$\alpha$ were examined in RAW 264.7 cells, in the presence of the herbal formulas. RAW 264.7 cells were incubated with LPS $1\;{\mu}g/mL$ and herbal formulas for 18 hours. As an in vivo, using a rat model of carrageenin-induced paw edema. The paw volume was measured at 2 and 4 hours following carrageenin-induced paw edema in rats. Results: 8 kinds of herbal formula inhibited NO production by LPS-stimulated in some concentration, but the effect of NO inhibition is weak. 12 kinds of herbal formula inhibited $PGE_2$ production by LPS-stimulated over the 30%. Among them Gumiganghwal-tang, Sagunja-tang, Samchulkunbi-tang, Insampaedok-san and Hwangryunhaedok-tang inhibited IL-6 production by LPS-stimulated but TNF-$\alpha$ was not inhibited. 12 kinds of herbal formula reduced the carrageenin-induced paw edema in rats. Particularly, 3 kinds of herbal formula(Gumiganghwal-tang, Ssanghwa-tang and Soshiho-tang) were better than indomethacin. Conclusion: These results suggest that Gumiganghwal-tang, Sangunja-tang, Samchulkunbi-tang, Insampaedok-san and Hwangryunhaedok-tang have antiinflammatory activity.

Angiotensin II (ANG II) has a biphasic effect on $Na^+$ transport in proximal tubule: low doses of ANG II increase the $Na^+$ transport, whereas high doses of ANG II inhibit it. However, the mechanisms of high dose ANG II-induced inhibition on $Na^+$ uptake are poorly understood. Thus the aim of the present study was to investigate signal transduction pathways involved in the ANG II-induced inhibition of $Na^+$ uptake in the primary cultured rabbit renal proximal tubule cells (PTCs) in hormonally defined serum-free medium. ANG II $(10^{-9}\;M)-induced$ inhibition of $Na^+$ uptake was blocked by losartan $(10^{-8}\;M,\;AT_1\;antagonist),$ but not by PD123319 $(10^{-8}\;M,\;AT_2\;antagonist)$ (P<0.05). ANG II-induced inhibition of $Na^+$ uptake was also completely abolished by neomycin $(10^{-4}\;M,$ PLC inhibitor), W-7 $(10^{-4}\;M,$ calmodulin antagonist), and $AACOCF_3\;(10^{-6}\;M,\;PLA_2\;inhibitor)$ (P<0.05). ANG II significantly increased $[^3H]arachidonic$ acid (AA) release compared to control. The ANG II-induced $[^3H]AA$ release was blocked by losartan, $AACOCF_3,$ neomycin, and W-7, but not by PD123319. ANG II-induced $[^3H]AA$ release in the presence of extracellular $Ca^{2+}$ was greater than in $Ca^{2+}-free$ medium, and it was partially blocked by TMB-8 $(10^{-4}\;M,$ intracelluar $Ca^{2+}$ mobilization blocker). However, in the absence of extracellular $Ca^{2+},$ it was completely blocked by TMB-8. In addition, econazole $(10^{-6}\;M,$ cytochrome P-450 monooxygenase inhibitor) and indomethacin $(10^{-6}\;M,$ cyclooxygenase inhibitor) blocked ANG II-induced inhibition of $Na^+$ uptake, but NGDA $(10^{-6}\;M,$ lipoxygenase inhibitor) did not affect it. In conclusion, $PLA_2-mediated$ AA release is involved in ANG II-induced inhibition of $Na^+$ uptake and is modulated by $[Ca^{2+}]_i$ in the PTCs.

Objectives: The purpose of this report is to examine the effect of $BL_{66}$ ${\cdot}$ $GB_{43}$ supplement and LIl ${\cdot}$ $GB_{44}$ draining in acupuncture for cerebral apoplexy treatment. Methods : I designed to investigate whether $BL_{66}$ ${\cdot}$ $GB_{43}$ supplement and $LI_1$ ${\cdot}$ $GB_{44}$ draining in acupuncture affects cerebral hemodynamics [regional cerebral blood flow(rCBF), mean arterial blood pressure(MABP)] in normal rats, and to make manifest whether $BL_{66}$ ${\cdot}$ $GB_{43}$ supplement and $LI_1$ ${\cdot}$ $GB_{44}$ draining in acupuncture is mediated by cyclooxygenase or guanylate cyclase. The changes of rCBF and MABP were determinated by laser-doppler flowmetry(LDF). Results : 1. $BL_{66}$ ${\cdot}$ $GB_{43}$ supplement and LI1 ${\cdot}$ $GB_{44}$ draining in acupuncture increased rCBF significantly, but decreased MABP. These results suggest that $BL_{66}$ ${\cdot}$ $GB_{43}$ supplement and $LI_1$ ${\cdot}$ $GB_{44}$ draining in acupuncture increased significantly rCBF by dilating pial arterial diameter(PAD). 2. By pretreatment with indomethacin(1 mg/kg, i.p.), the effect of $BL_{66}$ ${\cdot}$ $GB_{43}$ supplement and $LI_1$ ${\cdot}$ $GB_{44}$ draining in acupuncture induced increase of rCBF was significantly inhibited, the decreased MABP by treatment with $BL_{66}$ ${\cdot}$ $GB_{43}$ supplement and $LI_1$ ${\cdot}$ $GB_{44}$ draining in acupuncture was increased. 3. By pretreatment with methylene blue($10{\mu}/kg$, i.p.), the increased rCBF by treatment with $BL_{66}$ ${\cdot}$ $GB_{43}$ supplement and $LI_1$ ${\cdot}$ $GB_{44}$ draining in acupuncture was decreased conversely, the decreased MABP by treatment with $BL_{66}$ ${\cdot}$ $GB_{43}$ supplement and $LI_1$ ${\cdot}$ $GB_{44}$ draining in acupuncture was decreased. and then increased. Conclusion : I suggest that $BL_{66}$ ${\cdot}$ $GB_43$ supplement and $LI_1$ ${\cdot}$ $GB_{44}$ draining in acupuncture has an anti-ischemic effect through the improvement of cerebral hemodynamics.

Objectives This study was intended to clarify the anti-inflammation and anti-oxidation effects of gamikyejakjimo-tang herbal acupuncture (GKHA) for osteoarthritis. Methods Osteoarthritis was induced by injection of MIA into right knee joint cavities of rats. Rats were divided into a total of 4 groups (n=8). The 4 groups were normal group, control group, positive comparison group and expeimental group. Indomethacin and GKHA were medicated for a total of 4 weeks. After that, functions of liver and kidney by AST, ALT, creatinine, BUN, DPPH and ABTS free radical scavenging activity, ROS (reactive oxygen species) production, NO (Total Nitric oxide), IL-$1{\beta}$, IL-6, TNF-${\alpha}$ production, weight changes in the hind legs of MIA-induced osteoarthritis rat, serum PGE2, TIMP-1, MMP-2, MMP-9, LTB4, hs-CRP, and white blood cells, neutrophils, lymphocytes, monocytes were measured. The volume of cartilage was observed by micro CT arthrography. H&E and Safranin-O staining were used to examine the injury of synovial tissue. Results 1. In the hind leg weight bearing measurement, level of weight was increased. 2. AST, ALT, BUN, creatinine were decreased. 3. The production of total white blood cell was decreased, and the production of neutrophils, lymphocytes, monocytes were significantly decreased. 4. The production of NO, PGE2, TIMP-1, MMP-2, MMP-9, LTB4 were significantly decreased, and the production of hs-CRP was also decreased but with no significance. 5. The cartilage volume was significantly increased. 6. In H&E staining and Safranin-O staning, the cartilage cell appeared to be proliferated, and proteoglycans appeared to be increased. Conclusions Based on the results above, Gamikyejakjimo-tang Herbal Acupuncture has anti-oxidation and anti-inflammation effects, which leads to suppressing the underlying causes and the progression of osteoarthritis.

Recently, the survival rates of extremely low-birth-weight (ELBW) infants have improved with the development of neonatal intensive care. However, these infants were susceptible to intestinal perforation due to prematurity, fluid restriction, and injection of indomethacin, etc. Because of the risks of transportation, anesthesia and surgery itself, peritoneal drainage has been compared with laparotomy. Through our experience, we investigate the usefulness of peritoneal drainage retrospectively. From 1997 to 2007, six ELBW (M:F=5:1) underwent primary peritoneal drainage for intestinal perforation. Their median birth weight was 685g (405~870) and gestational age was $25^{+1}$ weeks ($24^{+3}{\sim}27^{+0}$). We noticed the intestinal perforation at median 10.5 days (8~18) after birth, and placed Penrose drain or Jackson-Pratt drain through right lower quadrant incision under local anesthesia. The cause of intestinal perforation was necrotizing enterocolitis in one patient, but that of the others was not clear. Three patients who showed normal platelet count and stable vital signs recovered uneventfully. Two patients (birth weight less than 500g) who showed unstable vital signs and low platelet count (12,000 / $mm^3$ to 30,000 / $mm^3$)expired despite aggressive resuscitation. One patient required laparotomy due to persistent intestinal obstruction after drain removal and survived. Our experience shows that peritoneal drainage was an acceptable treatment for ELBW infants and the prognosis was related to vital sign and platelet count at the time of intestinal perforation, and birth weight.

Bartter syndrome is an inherited renal tubular disorder characterized by hypokalemia, hypochloremic metabolic alkalosis, hyperreninemia, hyperprostaglandinism, and normal blood pressure. Bartter syndrome is classified by neonatal and classic type. Clinical manifestation of Bartter syndrome considered in dental treatment include tendency to dehydration, vomiting and erosion, attrition and abrasion of the teeth. A 2-year-4 month old boy with Bartter syndrome type III was referred to the Seoul National University Dental Hospital for dental evaluation and treatment. He showed hypokalemic hypochloremic metabolic alkalosis and had been treated with indomethacin and potassium chloride. He had hypocalcified teeth with or without multisurface caries lesions in all dentition and the erosion of maxillary teeth was detected. Dental procedure under general anesthesia was scheduled due to multiple caries and his medical condition. The dental procedure was successfully performed. This case suggests that electrolyte imbalances need to be treated prior to dental treatment and complete coverage restoration is necessary to protect the eroded teeth. An appropriate management plan for the patients with Bartter syndrome should include considerations of the need for close interaction with the pediatrician for pre- and post-operative care. General anesthesia may be recommendable to manage the patients having multiple caries with Bartter syndrome.

Phallus impudicus var. impudicus L. is an edible mushroom that has long been used as folk medicine in China. The aim of this study was to evaluate the antioxidant, anti-cholinesterase, and inflammation inhibitory activities of a methanol extract of fruiting bodies of P. impudicus var. impudicus L. The extract exhibited good 1,1-diphenyl-2-picrylhydrazyl scavenging activity, excellent ferrous ion chelating activity, and moderate hydroxyl radical scavenging activity compared with BHT at 2.0 mg/ml. However, the reducing power of the extract was significantly lower than that the BHT positive control. Although the inhibitory activities of methanol extract on acetylcholinesterase and butyryl cholinesterase were significantly lower than the galanthamine positive control at the concentration tested, the inhibition of acetylcholinesterase and butyryl cholinesterase was 52.83% and 55.17%, respectively, at 1.0 mg/ml. The methanol extract also demonstrated excellent inhibition of inflammation-related activities, such as production of nitric oxide in lipopolysaccharide-induced RAW 264.7 macrophage cells and acute edema induced by administration of carrageenan on the hind paw of rats. The collective results suggest that the fruiting body of P. impudicus var. impudicus L. might be a good source of antioxidant, anti-cholinesterase, and anti-inflammation compounds.

This study was conducted to evaluate the vasorelaxant effect of DangGuiSu-San and SamHwangSaSim-Tang extract on contracted rabbit carotid artery. To study the effect of DangGuiSu-San and SamHwangSaSim-Tang extract on contracted rabbit carotid arterial strips, arterial strips with intact or damaged endothelium were used for experiment using organ bath. The pre-contracted arterial strips with Phenylephrine(PE) was treated with various concentrations of DangGuiSu-San and SamHwangSaSim-Tang extract(0.01, 0.03, 0.1, 0.3 and $1.0mg/m{\ell}$). To determine the mechanisms of DangGuiSu-San and SamHwangSaSim-Tang-induced vasorelaxant, DangGuiSu-San and SamHwangSaSim-Tang extract were infused into contracted arterial rings which had been pretreated by indomethacin(IM), tetraethylammonium chloride(TEA), $N{\omega}$-nitro-L-arginine ($_L-NNA$), methylene blue(MB). And calcium chloride(Ca) 1 mM was infused into precontracted arterial ring induced by PE after treatment of DangGuiSu-San and SamHwangSaSim-Tang extract in $Ca^{2+}$-free krebs solution. DangGuiSu-San and SamHwangSaSim-Tang extract revealed significant relaxation on PE-induced arterial contraction. DangGuiSu-San and SamHwangSaSim-Tang extract also had an effective relaxation to the intact endothelium arterial ring. SamHwangSaSim-Tang extract on contracted rabbit carotid artery is related with NO-cGMP pathway. Pretreatment of DangGuiSu-San and SamHwangSaSim-Tang extract inhibited the contraction by influx of extracellular $Ca^{2+}$ in contracted arterial ring induced by NE. This study indicated that the relaxation effect of SamHwangSaSim-Tang extract on contracted rabbit carotid artery is related with NO-cGMP pathway. Pretreatment of DangGuiSu-San and SamHwangSaSim-Tang extract inhibited the contraction by influx of extracellular $Ca^{2+}$ in contracted arterial ring induced by NE.
