Bambusae Caulis in Liquamen(BCL) has been used to relieve the cough and asthma, and remove the phlegm in traditional Oriental medicine. In recent years, it was studied for its antiinflammatory, antiallergenic, immune-modulating, and anticarcinogenic capabilities. This experiment was performed to evaluate the microarray profiles of CD genes in human mast cells before and after BCL treatment. The results are as follows: The expression of 51 of the genes studied was up-regulated in the Bel-treated group; they include the genes coding L apoferritin, beta-2-microglobulin, ferritin light polypeptide, CD63, monocyte chemotactic and activating fact, heme oxygenase 1, CD140a, integrin alpha M, colony stimulating factor 2 receptor, eukaryotic translation elongation factor, CD37, interleukin 18, NADH dehydrogenase 1 beta, CD48, 5-lipoxygenase activating protein, interleukin 4, ribosomal protein L5, GABA(A) receptor-associated protein, beta-tubulin, integrin beta 1, CD162, CD32, lymphotoxin beta, alpha-tublin, integrin alpha L, CD2, CD151, CD331, 90 kDa heat shock protein, CD59, CD3Z, microsomal glutathione S-transferase 2, CD33, CD162R, cyclophilinA, CD84, interleukin 9 receptor, interleukin 11, CD117, CD39-Like 2, and so forth. The expression of 7 of the genes studied was down-regulated in the BCL-treated group; they include the genes coding con, CD238, SCF, CD160, CD231, CD24, and CD130. Consequently, the treatment of BCL on the human mast cells increased the expression of 51 genes and decreased the expression of 7 genes. These data would provide a fundamental basis to the traditional applications of Bambusae Caulis in Liquamen.

We have previously observed that Bambusae Caul is in Liquamen (BCL) stimulates the adipose conversion of 3T3-L1 cells and molecular chaperones were involved in the process of the assembly and replacement of laminin subunits in Bovine aortic endothelial cells(BAEC). Endothelial cells are exposed to continuous shear stress due to the blood flow. Heat shock protens(hsp) are a well-known stress response protein, namely, stress proteins. To investigate effects of BCL on the stress proteins induced by heating in endothelial cells, we have analyzed synthetic amounts of stress proteins in sodium dodecyl sulfate gel electrophoresis under reducing conditions. Under the condition of heating stress, BCL inhibited the synthesis of stress proteins in endothelial cells. These results suggest that BCL may have an important role for expression of stress proteins induced by heating in endothelial cells.

Bambusae Caulis in Liquamen(BCL) has been commonly prescribed for stroke patients in the traditional Oriental medicine. So this study is aims to investigate the anti-apoptotic and neuroprotective effects of Bambusae Caulis in Liquamen(BCL) manufactured by different production process on the focal ischemia induced by intraluminal filament insertion in rats. The focal ischemia was induced by intraluminal filament insertion into middle cerebral artery. The animals were divided into four groups (n=15 in each group). The ischemia induced and not treated group : Control group, the ischemia induced and oral medication of the three kinds of BCL : BCL-A group, BCL-B group, BCL-C group. BCL-A was produced by heating at a low temperature$(250^{\circ} C)$ in electric kiln and filtering. BCL-B was produced by heating at a high temperature$(900^{\circ} C{\sim}1,000^{\circ}C)$ in yellow earth kiln and refining and filtering. BCL-C was produced by heating at a low temperature$(400^{\circ} C)$ yellow earth kiln and no refining and filtering. The anti-apoptotic and neuroprotective effects of the oral medication of BCL were observed by Bax, BCL-2, cytochrome c, mGluR5, cresyl violet and ChAT-stain. Our study suggests that BCl-A(was produced by heating at a low temperature in electric kiln and filtering) and BCL-C(was produced by heating at a low temperature in yellow earth kiln and no refining and filtering) show anti-apoptotic and neuroprotective effects on the focal ischemia induced by intraluminal filament insertion in rats and BCL-C is more effective than BCL-A.

This study was designed to investigate the effects of Samul-tang Extract and Bambusae caulis in liquamen(SEB) on the changes in regional cerebral blood flow (rCBF) and mean arterial blood pressure (MABP) in normal rats. The results were as follows ; SBE significantly increased rCBF in a dose-dependent manner, and increased MABP in a dose-dependent manner. This result suggests that SBE significantly increased rCBF by dilating pial arterial diameter. Increase of SBE-induced rCBF was significantly inhibited by pretreatment with indomethacin (1 mg/kg, i.p.), an inhibitor of cyclooxygenase and increase of SBE-induced rCBF was inhibited by pretreatment with methylene blue ($10\;{\mu}g/kg$, i.p.), an inhibitor of guanylate cyclase. Increase of SBE-induced MABP was significantly increased by pretreatment with methylene blue but increase of SBE-induced MABP was decreased by pretreatment with indomethacin. These results suggested that the action of SBE was mediated by cyclooxygenase.

The study was designed to investigate the effects of Mixture of Yukgunja-tang and Bambusae Caulis in Liquamen (YTBCL) on the change of regional cerebral blood flow (rCBF) and mean arterial blood pressure (MABP) in rats, and further to determine the mechanism of action of YTBCL. The results in rats were as follows ; YTBCL 25 ${\mu}l$ significantly decreased rCBF and MABP compared with basal condition. YTBCL 100 ${\mu}l$ significantly increased rCBF compared with basal condition, but decreased MABP compared with basal condition. YTBCL 50 ${\mu}l$ significantly increased rCBF compared with basal condition, but MABP was somewhat decreased compared with basal condition. The VTBCL 50 ${\mu}l$-induced increase in rCBF was significantly inhibited by pretreatment with methylene blue (10 ${\mu}g$/kg, i.p.), an inhibitor of guanylate cyclase and indomethacin (1 mg/kg, i.p.), an inhibitor of cyclooxygenase. The YTBCL 50 ${\mu}l$-induced decreased MABP significantly increased by pretreatment with methylene blue but was inhibited by indomethacin. This results were suggested that the mechanism of YTBCL was mediated Dy guanylate cyclase.
