Zanthoxylum schinifolium (Z. schinifolium) and the seed oil of Z. schinifolium has been widely used as culinary applications and traditional medicine for epigastric pain in Korea, China, and several Asia nations and the components or extracts of Z. schinifolium have been reported to have pharmaceutical effects such as anti-platelet aggregation, inhibitory activities against monoamine oxidase, antioxidant and anticancer activities, and anti-inflammatory activity. In this study we got the results that 200 mg/kg/day seed oil of Z. schinifolium oral administration for 13 weeks enhances most immune-related cells and is biologically safe. However as B cell population was increased by Z. schinifolium seed oil administration but B cell function was not changed by that, ultimately we deduced that Z. schinifolium seed oil doesn't have the modulation effect about B cell. To evaluate the biological safety of repeated Z. schinifolium seed oil administration the index of biological safety such as CBC, hematological enzymes, and especially histopathological morphologies was measured but no changes related with Z. schinifolium seed oil administration had been shown. Conclusively Z. schinifolium seed oil is one of the safe candidates to modulate immunity.

Objectives : The purpose of present study is to investigate the influence of a spinal gamma-aminobutyric acid B (GABAB) receptor on a central regulation of blood pressure(BP) and heart rate(HR), and to define its mechanism in the spinal cord. Methods : In urethane-anesthetized, d-tubocurarine- paralyzed and artificially ventilated male Sprague-Dawley rats, intrathecal administration of drugs were carried out using injecton cannula(33-gauge stainless steel) through the guide cannula(PE 10) which was inserted intrathecally at lower thoracic level through the puncture of a atlantooccipital membrane. Results : Intrathecal injection of an GABAB receptor agonist baclofen(30, 60, 100 nmol) decreased both blood pressure and heart rate dose-dependently. Pretreatment with 8-bromo-cAMP(50 nmol), a cAMP analog or glipizide(50 nmol), a ATP-sensitive K+ channel blocker attenuated the depressor and bradycardic effects of baclofen (100 nmol) but not with 8-bromo-cGMP(50 nmol) a cGMP analog. Conclusions : The GABAB receptor in the spinal cord plays an inhibitory role in central cardiovascular regulation and that this depressor and bradycardic actions are mediated by the decrease of cAMP via the inhibition of adenylate cyclase and the opening of K+ channel.

<P><B>Abstract</B></P> <P><B>Background</B></P> <P>Recurrence patterns or survival in colorectal cancer patients might differ according to inferior mesenteric lymph node (IMLN) metastasis. However, few studies have compared para-aortic lymph node (PALN) metastasis and IMLN metastasis. The aim of the current study is to identify survival and recurrence patterns in patients with sigmoid colon and rectal adenocarcinoma with either PALN or IMLN metastasis and to evaluate the prognostic significance of PALN and IMLN metastasis.</P> <P><B>Methods</B></P> <P>A retrospective study involving 3076 patients with stage III and IV sigmoid and rectal cancer, who underwent curative surgery between January 2000 and December 2009, was performed. Clinicopathologic features, recurrence patterns, and survival outcomes of 27 patients with PALN metastasis were compared with those of 47 patients with IMLN metastasis. Patients with both IMLN and PALN metastasis were included in the PALN+ group.</P> <P><B>Results</B></P> <P>After curative resection, there was no significant difference in the 5-year disease-free and overall survival rates between the PALN+ and IMLN+ groups (27.5% <I>vs</I>. 29.8%, <I>p</I> = 0.24, and 37% <I>vs</I>. 39.2%, <I>p</I> = 0.19, respectively). Furthermore, there were no significant differences in recurrence rate (PALN+ group, 70.4%; and IMLN+ group, 63.8%; <I>p</I> = 0.69) or recurrence patterns.</P> <P><B>Conclusions</B></P> <P>The results suggest that IMLN metastasis, similar to PALN metastasis, is associated with adverse oncologic outcomes and has prognostic significance. Therefore, it is preferable that IMLN metastasis should be considered under the category of systemic metastasis (M1).</P>

Vascular smooth muscle contraction is mediated by activation of extracellular signal-regulated kinase (ERK) 1/2, an isoform of mitogen-activated protein kinase (MAPK). However, the role of stress-activated protein kinase/c-Jun N-terminal kinase (JNK) in vascular smooth muscle contraction has not been defined. We investigated the role of JNK in the contractile response to norepinephrine (NE) in rat aortic smooth muscle. NE evoked contraction in a dose-dependent manner, and this effect was inhibited by the JNK inhibitor SP600125. NE increased the phosphorylation of JNK, which was greater in aortic smooth muscle from hypertensive rats than from normotensive rats. NE-induced JNK phosphorylation was significantly inhibited by SP600125 and the conventional-type PKC (cPKC) inhibitor Go6976, but not by the Rho kinase inhibitor Y27632 or the phosphatidylinositol 3-kinase inhibitor LY294002. Thymeleatoxin, a selective activator of cPKC, increased JNK phosphorylation, which was inhibited by $G{\ddot{o}}6976$. SP600125 attenuated the phosphorylation of caldesmon, an actin-binding protein whose phosphorylation is increased by NE. These results show that JNK contributes to NE-mediated contraction through phosphorylation of caldesmon in rat aortic smooth muscle, and that this effect is regulated by the PKC pathway, especially cPKC.
