Objectives : This research was investigated the anticoagulant effect of the Gleditsiae spina extract. Methods : We researched prothrombin time (PT) assay, activated partial thromboplastin time (APTT) assay in vitro and in vivo using arteriovenous (A-V) shunt rat model and shortening Rat tail bleeding time (BT). A-V shunt and BT were treated with extract of Gleditsiae spina (GS) 400 mg/kg for a week. Results : Bleeding time of Gleditsiae spina extract in vivo had a significant increase as about 1.2 times and thrombus weight of Gleditsiae spina extract had a significant reduction of thrombus weight as 26%. Gleditsiae spina extract represented an effect of anticoagulation by operating on extrinsic pathway factor II, V, VII, X and intrinsic pathway factor VIII, IX, X, XI, XII in the coagulation system. Conclusions : Considering the above mentioned results, it is judged that a Gleditsiae Spina extract has a control effect of thrombus creation.

Purpose: Gleditsiae spina (GS) has been used to treat patients with several diseases such as carbuncle, swelling and parasites. Recently GS is known to have anticancer activity in abdominal solid tumor, but the effects of GS on breast cancers is not clarified. For these reasons, we investigated effects of Gleditsiae spina (GS) on gene expression of human breast cancer cells. Methods: We investigated the effects of GS on proliferation of breast cancer cell line, MDA-MB-231. In addition, the genetic profile for the effect of GS on breast cancer cells was measured using microarray technique, and the functional analysis on these genes was conducted. Results: Total 1,434 genes were up-regulated and 2,483 genes down-regulated in the cells treated with GS. Genes induced or suppressed by GS were all mainly concerned with metabolic process, regulation of biological process and protein binding. The network of total protein interactions was measured using cytoscape program, and some key molecules that can be used for elucidation of therapeutical mechanism of medicine in future were identified. Conclusion: These results suggest possibility of GS as anti-cancer drug for breast cancer, and also suggest that related mechanisms are involved in regulation of intra-cellular metabolism in breast cancer cells.

GLEDITSIAE SPINA (GS) has been used as folk remedies traditionally for treatment of antiphlogistic and antifebrile agents. An ethanol extract and its fraction of GS were assessed to determine the mechanism of its antioxidant activity. Also, inhibitory effect of extract from GS and its fraction measuring the inhibitory effect on $Cu^{2+}$-induced human low-density lipoprotein (LDL) oxidation. GS ethanol extract and its fraction exhibited a concentration-dependent reactive oxygen species (ROS) and reactive nitrogen species (RNS) scavenging activities, including trolox equivalent antioxidant capacity (TEAC), OPPH radical, superoxide anion, hydroxyl radicals, peroxynitrite and nitric oxide, using different assay systems. Furthermore, the GS ethanol extract and its fraction showed dose-dependent protection of LDL oxidation induced by $CuSO_4$. In addition, the GS ethanol extract and its fraction were characterized as containing a high amount of total phenolics. These results suggest that GS ethanol extract and its fraction might be helpful for preventing oxidative stress and protecting LDL oxidation.

This study was designed to investigate the effects of Gleditsiae Spina (GS) on polycystic ovary (PCO) induced by estradiol valerate in female rats. We investigated the effects of GS on changes in body weights and food and water uptake for 5 weeks. In addition, we also examined the effects on ovary weights. Finally, we observed histopathological changes in PCO rats. Treatment with GS did not affect body weights, amount of food and water uptake compared with non-treated control group. Administration group of GS restored body/ovary weight ratio to normal levels, which were lowered by induction of PCO. In histopathological observation, formation of cysts was suppressed in GS group compared with non-treated control group. These results suggest that GS can be used for patients with PCO to prevent formation of cystic follicles and malfunction of ovary.

Objective : The purpose of this research is to examine the effects of Gleditsiae Spina (GS) extract on immune cells and cytokines in ovalbumin (OVA)-induced asthmatic mice. Methods : In vivo, C57BL/6 mice were sensitized and handicapped by OVA for 12 weeks. During this experiment, the one group was then treated with GS extract for the later 8 weeks (3 times per week) and analyzed by ELISA, flow cytometer and RT-PCR. Results : In vivo, there were significant decreases in eosinophils, IL-4, IL-5, IL-13, IgE in BALF (bronchoalveolar lavage fluid). However, $IFN-{\gamma}$ in BALF of GS group increased significantly, compared with that of control group. Additionally, the population of $CD3e^-/CCR3^+,\;CD69^+/CD3e^+,\;IgE^+/B220^+,\;CD11b^+/Gr-l^+$ cells in the GS group decreased. Conclusion : The results of this study support a role for GS as an effective treatment for asthma in its experimental success in significantly decreasing inflammation and asthma reactions, and in increasing $IFN-{\gamma}$, which helps prevent such reactions.

Objectives : This study was designed to investigate the effects of Gleditsiae spina(GS) on changes in cerebral blood flow in rats. Methods : The present study was investigated regional cerebral blood flow(rCBF) and mean arterial blood pressure(MABP) in rats. In addtion, the present study also investigated action mechanisms of GS on changes in rCBF and MABP by Pre-treatment with indomethacin(IDM) and methylene blue(MTB), an inhibitor of a vasodepressor material. Results : Treatment with GS elevated rCBF in dose-dependent manner, but MABP levels were not affected by treatment with GS. Pre-treatment with indomethacin(IDM), an inhibitor of cyclooxygenase, inhibited increase of rCBF effectively. And pre-treatment with methylene blue(MTB), an inhibitor of guanylate cyclase, inhibited increase of rCBF induced by GS too. In addition, Pre-treatment with MTB inhibited increase of MABP too. But, pre-treatment with IDM did not affect MABP levels. Conclusions : These results suggest that GS is effective to treat patient with disease related to cerebral ischemia, because GS can increase rCBF. In addition, the mechanisms are thought to be related to both of cyclooxygenase and guanylate cyclase pathways.

Purpose: In the theory of traditional medicine, Glenditsia spina(GS) can resolve carbuncle, relive swelling, dispel wind and destroy parasites. This study was designed to investigate the effects of GS on gene expression of ovarian tissue in polycystic ovary syndrome(PCOS) rats. Methods: In this experiment, female rats injected with a single dose of 2 mg estradiol valerate(EV) and GS was given for 5 weeks. The genetic profile for the effects on ovarian tissue in PCOS rats was measured using microarray technique, and the functional analysis on these genes was conducted. Results: 985 genes were increased in control and restored to normal level in GS group. (B), 733 genes were decreased in control group and restored to normal level in GS group. (F). Metabolic pathways related in B group genes were Graft-versus-host disease, Allograft rejection, Autoimmune thyroid disease, Cytokine-cytokine receptor interaction, Small cell lung cancer, Type I diabetes mellitus. Metabolic pathways related in F group genes were Antigen processing and present, Adipocytokine signalling pathway, Focal adhesion, ECM-receptor interaction, Pancreatic cancer, Notch signalling pathway, Tight junction. The network of total protein interactions was measured using cytoscape program, and some key molecules, such as c-Fos, c-Myc, ABL1 related in B group, MAPK8, RASA1, CALR related in F group that can be used for elucidation of therapeutical mechanism of medicine in future were identified. Conclusion: These results suggest possibility of GS as anti-cancer and anti-hyperplasia drug in PCOS. In addition, the present author also suggests that related mechanisms are involved in suppression of proto-oncogene such as c-Fos, c-Myc and ABL1, and in regulation of cell cycle such as RASA1.
