The purpose of this research was to investigate effects of Bambusae Caulis in Liquamen (BCL) on the synthesis of basement membrane proteins during proliferation and differentiation of 3T3-L1 cells. BCL has been used to relieve the cough and asthma, and remove phlegm in traditional oriental medicines. In recent years. it was studied for its antiinflammatory, antiallergenic. immune-modulating and anticarcinogenic capabilities. We have previously observed that glycyrrhizin stimulates the adipose conversion of 3T3-L1 cells. To investigate effects of BCL on the basement membrane proteins during proliferation and differentiation of 3T3-L1 cells, we have analyzed synthetic amounts of basement membrane components such as type IV collagen and BM40. BCL stimulated the synthesis and secretion of type IV collagen from both 3T3-L1 preadipocytes and adipocytes. The synthesis and secretion of BM40 was not affected by BCL. The continuous addition of BCL markedly stimulated cell growth and increased cell density. These results suggest an important role for type IV collagen in adipocyte differentiation.

The purpose of this research was to investigate effects of Bambusae Caulis in Liquamen(BCL) on T-lymphocytes and peritoneal macrophages in mice. The apoptosis and subpopulation of T-lymphocytes were tested using a flow cytometer. The phagocytic activity of mouse peritoneal macrophage was tested using a luminometer. Nitric oxide production was tested using a Griess reagents. BCL induced T-lymphocytes apoptosis. BCL increased $T_H$ cells population and decreased $T_C$ cells population of T-lymphocyte, but did not affect splenocytes subpopulation. BCL increased nitric oxide production and phagocytic activity of peritoneal macrophage in mice. These results suggest that BCL regulates the immune system in consequence of an increase in helper T cell population and macrophages activation.

Objectives : Intestinal epithelial cell damage is closely associated with various intestinal diseases, such as Inflammatory Bowel Disease (IBD), Celiac Disease and Gastroenteritis, and it plays a crucial role in the development and progression of intestinal diseases. Therefore, it is important to develop drugs that target protection of intestinal epithelial cells. Here, we aimed to investigated whether Bambusae Caulis in Liquamen (BCL) against t-BHP induced oxidative stress injury in human intestinal epithelial cells and to explore the underlying molecular mechanism. Methods : In this study, we performed MTT assay, measurement of ROS generation, and immunoblot analysis to determine the cytoprotective efficacy in HT29 cells (human colorectal adenocarinoma cell line with epithelial morphogy). Results : First, we checked that BCL was not cytotoxic up to concentration 30 ㎍/mL in HT29 cells. Then, we confirmed that BCL inhibited t-BHP-induced ROS and cell death. BCL also reversed the expression of proteins associated apoptosis. Next, to confirm the relationship between efficacy of BCL and Nrf2, we conducted experiments using siNrf2. Asresult, the effects of inhibiting ROS production and cell death of BCL was reversed by siNrf2. Conclusion : BCL prevents t-BHP-induced oxidative stress and apoptosis. And the efficacy of BCL is related to Nrf2 activation.

Objectives : Bambusae Caulis in Liquamen (BCL) has been used for stamina fortification in Oriental Medicine for thousand years. The goal of the present study was to investigate the muscle antifatigue effect of BCL. Methods : The mice were divided into three groups. The control group was allowed to swim for 10 minutes without BCL infusion. For the preventive effect of BCL, another group referred to BCL-1 was fed with BCL an hour before the swimming exercise. BCL-2 group for the reversion effect was forced to swim for 10 minutes at first, then fed with BCL followed by half an hour rest and another 10 minute swimming exercise. All the serum samples collected by heart puncture were used for the measuring biochemical factors such as LDH, CPK, glucose, lactate, triglycerides and total cholesterol. Results : In the BCL-2 group, lactate and LDH were significantly reduced compared to the control. BCL infusion during the exercise was effective in metabolizing LDH, reducing the conversion ratio of pyruvate into lactate. In the BCL-1 group, it was not effective in antifatigue function. The level of glucose was significantly reduced in BCL-1 group compared to the control. When the BCL was infused before the exercise, it is assumed that glycogenolysis seen during the exercise was prevented. When the BCL was infused during the exercise, the triglycerides and total cholesterol were increased significantly compared to the control. BCL seems to cause the increase of lipolysis to utilize the fat as an energy source. Unlike other parameters, CPK did not show any changes from BCL infusion. Conclusions : Based on the above results, BCL is found to be involved in energy metabolism. Further studies are needed to find out the underlying mechanism of BCL for its effect on stamina fortification.

This study was performed to investigate the effects of Bambusae Caulis in Liquamen (bamboo extract) on the changes of antioxidant enzymes and histopathological changes of liver and kidney in mice when administered in different dosages. The experimental groups were divided into four. For control group, 0.9％ NaCl (0.2 ml/25 g B.W.) and for experimental groups, 5% (H1 group), 10% (H2 group), and 20%(H3 group) bamboo extract diluted with 0.9％ NaCl, were administered (0.2 ml/25 g B.W.) respectively for 28 days at an interval of 48 hours. MnSOD activities were increased in H1 group (46%, P<0.05), H2 group (40%, P<0.05), and H3 group (34%, P<0.05) as compared to the control group. CuZnSOD activities were increased in H1 group (11%, P<0.05), but were decreased in H3 group (13%, P<0.05). The activities of catalase were decreased in H1 group (39%, P<0.05), H2 group (34%, P<0.05), and H3 group (31%, P<0.05) as compared to the control group. Histopathological observation revealed ballooned hepatocytes in the pericentral and periportal veins of H1 group. More ballooned and injured hepatocytes than in H1 group were observed in the H2 and H3 groups. Detachment of endothelial cells of the central vein was observed in the H2 and H3 groups. These results indicated that bamboo extract developed dose-dependent changes in antioxidant enzyme activities and developed histopathological changes of liver and kidney.

Objectives : Bambusae Caulis in Liquamen (BCL), a traditional herbal medicine, is a distilled product of condensation from the burning of fresh bamboo stems. We previously identified the anti-oxidant capacity of BCL in hepatocytes and suggested that BCL is a promising therapeutic candidate for treating oxidative stress-induced hepatocellular damage. Despite the importance of the role played by Kupffer cells in liver disease, the efficacy of BCL on Kupffer cells is unclear. Therefore, this study aimed to determine whether BCL could suppress LPS-induced inflammation and LPS+ATP-induced inflammasomes in Kupffer cells. Methods : We used ImKCs, a murine immortalized Kupffer cell line to examined whether BCL inhibited LPS-induced inflammation response and oxidave stress. And, we prepared a total of 18 L of BCL, purchased from Bamboo Forest Foods Co., Ltd. (648 Samdari, Damyang-eup, Damyang-gun, Jeollanam-do, Republic of Korea), was concentrated using a decompression concentrator. Result : The LPS-induced release of inflammatory cytokines was abolished by BCL treatment. Also, BCL treatment suppressed the LPS+ATP-induced expression of inflammasome proteins (NLRP3, IL-1, and IL-18), and inhib β ited the release of IL-1 . BCL decreased LPS-or LPS+ATP-induc β ed reactive oxygen species production. In addition, BCL increased nuclear translocation of Nrf2 and the expression of HO-1 in a time-dependent manner. Conclusion : These results suggest the efficacy of BCL with respect to its anti-inflammatory and anti-inflammasome effects mediated by Nrf2 in Kupffer cells.

The purposes of this study were to investigate effects of Bambusae Caulis in Liquamen(BCL) on antioxidant activities and inhibitory activities of HMG-CoA reductase of in vitro, and lipid metabolism in rats fed the high cholesterol diet in vivo. Sprague-Dawley male rats weighing l00$\pm$10 g were devided into five groups ; normal group(NOR), the high cholesterol diet administered group(1 $\%$ cholesterol and 0.25$\%$ sodium cholate)(CON), 5$\%$ BCL administered group (5BL), the high cholesterol diet and 5$\%$ BCL administered group (5BCB) and the high cholesterol diet and 10\$\%$ BCL administered group (10BCB), respectively. In antioxidative activities of BCL using Rancimat in vitro, 1.25 diulent and original solution were more excellent activities than the control group, and in inhibiting activities of HMG-CoA reductase, BCL was shown inhibitory effects compared with the control, in dose dependent manners, especially 57.9$\%$ in original solution and 36.0$\%$ in 1.25 diulent. The growth rate of the control group was higher than the normal group, wheras the group given 5$\%$ BCL and 10$\%$ BCL were gradually decreased, especially the most excellent effect in 10$\%$ BCL. Serum levels of total cholesterol, LDL-cholesterol, triglyceride and free cholesterol were significantly decreased, whereas levels of HDL-cholesterol and phospholipid were increased, but not significantly. BCL administered group was increased in HDL-cholesterol/total cholesterol ratio and lowered antherogenic index. The activities of AST in serum were rather lowered in the BCL administration group than the cholesterol diet group, but not in ALT and ALP. The hepatic contents of total cholesterol were lowered significantly than control group, but not in triglyceride. Therefore, it might be expected that BCL is believed to be a possible protective or curative effects for fatty livers and hyperlipidemia-induced by a hi~h cholesterol diet.

The purpose of this study was to investigate the effects of the Bambusae Caulis in liquamen (BCL) on blood circulation in animal models. Previous studies on BCL have shown effects on thrombolytic activity and angiotensin-converting enzyme (ACE) inhibitory activity. In the mouse model, the triglyceride content were 301.5 mg/dL in the high fat diet+BCL II 0.01% group, 289.2 mg/dL in the high fat diet+BCL II 0.05% group, which was significantly lower than the high fat diet group. The total cholesterol content was 311.9 mg/dL in high fat diet+BCL II 0.01% and 293.7 mg/dL in high fat diet+BCL II 0.01% 0.05%, respectively, which was significantly lower than the high fat diet group. The HDL-cholesterol level was 206.0 mg/dL for the high fat diet, 196.6 mg/dL for the high fat diet+BCL II, and 189.2 mg/dL for the high fat diet+BCL II. There was no significant difference between the 0.01% and 0.05% groups. The high-fat diet+0.05% group was significantly improved in the blood flow compare to the high fat diet and the high fat diet+0.01% group. Platelet aggregation inhibition ability was inhibited in the high fat diet+0.01% and 0.05% groups compared to the high fat diet group.
