Objectives: This study was performed in order to investigate the anti-hemolytic effect of Chunghyuljihwang-tang(CHJHT, Qingxuedihuang-tang) on phenylhydrazine-induced hemolytic anemia in Rats. Materials and Methods: Hemolytic anemia model of rats were induced by phenylhydrazine(PHZ, 40mg/kg/day, i.p.) for 3days. Male Sprague-Dawley rats were divided into three groups for their treatment. Normal group was injected normal saline for 3 days with distilled water(d.w.) orally, control group was injected PHZ for 3 days with d.w. and CHJHT group was injected PHZ for 3 days with administration of CHJHT for 10 days. RBC(Red blood cell), Hb(hemoglobin), mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, reticulocyte were determined on day 0, 4, 7, 10. Body weight was investigated on day 0, 2, 4, 6, 8, 10 and the weight of spleen was measured on day 10. Results: For CHJHT group, the levels of RBC and Hb were significantly higher than control group on day 4, and the concentration of hemoglobin on day 7 was increased more than control group. Moreover, reticulocyte was significantly decreased on day 10 more than control group. These results could be concluded that CHJHT suppressed the hemolytic anemia by PHZ and improved hematological values of anemia earlier.

Objectives : In the present study, the authors intended to investigate whether two oriental medical prescriptions named chwiyeon-tang and chihyosan-gamibang significantly affect much release from cultured hamster tracheal surface epithelial HTSE cells. Methods : Confluent HTSE cells were metabolically radiolabeled with 3H-glucosamine for 24 hrs and chased for 30 min in the presence of chwiyeon-tang or chihyosan-gamibang to assess the effect of each agent on 3H-mucin release. Possible cytotoxicities of each agent were assessed by measuring lactate dehydrogenase LDH release. Also, the effect of chwiyeon-tang and chihyosan-gamibang on contractility of isolated tracheal smooth muscle were investigated. Results : (1) Chwiyeon-tang significantly inhibited mucin release from cultured HTSE cells, with significant cytotoxicity ; (2) Chihyosan-gamibang significantly stimulated mucin release from cultured HTSE cells, with minute cytotoxicity ; (3) Chwiyeon-tang and Chihyosan-gamibang did not affect contractility of isolated tracheal smooth muscle. Conclusions : We suggest that the effects of Chwiyeon-tang and Chihyosan-gamibang with their components should be further investigated and it is of great value to find, from oriental medical prescriptions, noel agents which might regulate mucin secretion from airway goblet cells.

In order to investigate the effect of 'Whangryonhaedok-Tang' on the anti-inflammatory, ileum of mice, blood pressure, blood glucose, total cholesterol and antibacterial activity, those pharmacological actions were conducted. The results of this studies were summarized as follows; Rat hind paw edema induced by acetic acid was inhibited. In mice, tone of intestinal smooth muscle was suppressed with the treatment of sample and intestinal contractions induced by $BaCl_2$ was inhibited. Hypertensive effect was not observed in rabbits but was observed by the water extract of 'Whangryonhaedok-Tang' excluded Phellodendri Cortex in rabbits. The increased blood glucose levels in alloxandiabetic rabbits were significantly decreased by the oral administration of the sample I after 6 days. The total cholesterol levels in alloxan-induced rabbits were significantly decreased by the oral administration of the sample I after 9 days. Antibacterial activity was observed. In addition, we thought the pharmacological actions were significantly noted by the sample III (Methanol soluble fraction) because of the purification of effective components.

This study was performed to evaluate hepatoprotective effect of Daewhang-whangryunhaedok-Tang(DWT) on liver injured rats induced by $CCl_4$ and the acute oral toxicity of it in mice. The activities of serum transaminase(ALT/AST), alkaline phosphatase(ALP) and lactic dehydrogenase (LDH), the levels of serum total cholesterol(TC) and triglyceride(TG), change of liver enlargement, and inhibitory activities of lipid peroxidation, catalase and glutathione-S-transferase(GST) in liver microsome were determined in hepatotoxic rats induced by $CCl_4$ DWT DWT was significantly reduced the serum ALT, AST, ALP, LDH, TC and TG levels. And, the increase of lipid peroxidation, decrease of catalase and GST activities in the liver microsome of $CCl_4$-intoxicated rat were significantly improved by the treatment of DWT. Male and female mice were administered maximum dosages of 5,000 mg/kg b.w. of DWT. After single oral administration of DWT to mice, we observed them daily for 2 weeks. DWT did not induce any toxic signs in the mortalities, clinical signs, body weight changes, and gross necropsy findings of mice. Based on these results, it is concluded that DWT may have the hepatoprotective effect on $CCl_4$ induced hepatotoxicity in rats. Also, DWT may have no side effect and its $LD_{50}$ value may be over 5,000 mg/kg b.w. in mice.

Objectives : This study was performed to evaluate the effects of Hwangryunhaedok-tang(Huanglianjiedu-tang HHT) water extract on locomotor dysfunction induced by spinal cord injury(SCI) in rats. Methods : SCI was induced by mechanical contusion following laminectomy of 10th thoracic vertebra in Sprague-Dawley rats. HHT was orally given once a day for 14 days after SCI. Neurological behavior was examined with the Basso-Beattie-Bresnahan locomotor rating scale. Tissue damage and nerve fiber degeneration were examined with cresyl violet and luxol fast blue staining. Using immunohistochemisty, cellular damage to neurons and nerve fibers were examined against Bax and MAP-2. As inflammatory response markers, iNOS and COX-2 expressions were also examined. Results : 1. HHT ameliorated the locomotor dysfunction of the SCI-induced rats. 2. HHT attenuated the reduction of motor neurons in the ventral horn of the SCI-induced rat spinal cord. 3. HHT significantly reduced the number of Bax positive cells in the peri-lesion of the SCI-induced rat spinal cord. 4. HHT attenuated the reduction of MAP-2 positive cells in the peri-lesion of the SCI-induced rat spinal cord. 5. HHT significantly reduced the number of iNOS and COX-2 positive cells in the peri-lesion of the SCI-induced rat spinal cord. Conclusions : These results suggest that HHT improves the locomotor dysfunction of SCI by protecting motor neurons from cell death through anti-inflammatory effect.
