Objectives: Samul-tang and Rhizome of Cyperus rotundus L. have been frequently used in gynecologic disease. The purpose of the present study is to explore the behavioral and neurobiological effects of Samul-tanggahyangbuja (SGH) on ovariectomized rats and to form a basis for clinical treatment. Methods: Ovariectomized rats were repeatedly stressed for over 2 weeks. After orally medicated with SGH (200 or 400 mg/kg/day), the anxiety response was tested using the Elevated Plus Maze (EPM) in rats. The serum levels of estradiol and IL-4, and immunohistochemical changes of IL-4 in the Locus coeruleus (LC) and Paraventricular Nucleus (PVN) were measured. Results: 1. In the EPM, SGH 400 mg significantly increased time spent on the open arms and decreased time spent on the closed arms, compared with the control group (p<0.05). 2. SGH tended to increase numbers of crossings in the open and closed arms in the EPM. However, it did not reach statistical significance. 3. SGH significantly increased the serum levels of estradiol compared with the control group (p<0.05). 4. SGH 400 mg significantly increased the serum levels of IL-4 compared with the control group (p<0.05). 5. IL-4 immunoreactivity was reduced in the control group compared with the normal group (p<0.05). However, SGH groups (200 and 400 mg) did not produce any significant effects on levels of IL-4 in the LC and PVN. Conclusions: These results suggest that SGH possesses the anti-depressant and immuno-modulatory effects on ovariectomized rats.

Peripheral axons in vertebrate animals can regenerate after nerve injury and accomplish its functional recovery. Numerous studies have revealed that diverse molecular factors are induced during axonal regeneration and their potential roles in axonal regeneration have been studied. Examples is N-CAM, L1, P0, nerve growth factors, GAP-43 and so forth. However, most of the studies on axonal regeneration have been primarily focused on axon fiber regrowth and elucidating molecular factors, and relatively less is known about functional recovery. Also, specific drugs or drug components used in the oriental medicine in relation to nerve fiber regeneration have not been known. And thus, in the present, a study on the effect of Samul-tang components and Samul-tang extracts to regeneration of peripheral axon fiber is underway by immunofluorescence staining. Therefore, this prior application of Samul-tang with documents consideration is reported with a plea for further investigation.

The present experiment was desined to examine catecholamines, 5-hydroxytryptamine, amino acids, malondialdehyde(MDA) and free radical scavening activity, by administering Samultang extract of a variety of concentraction to senile brain The results were summarized as followings: 1. Samultang significantly increased noradrenaline in the cortex, striatum, hippocampus and hypothalamus of the brain tissue of senile rats, and even though Samultang increased noradrenaline also in other brain tissue, there was no significance. 2. Samultang had effects on dopamine changes in hypothalamus of the brain tissue of senile rats. 3. Samultang significantly increased 5-hydrotryptamine in pons-medulla oblongota and cerebellum, but decreased in hypothalamus. 4. Samultang increased amino acid in the brain tissue of senile rats. 5. Samultang significantly decresed lipid peroxide production in the brain tissue of senile rats. 6. Samultang significantly decresed MDA and free radical in the brain tissue of senile rats. According to the above results, Samultang is assumed to improve brain function by reacting on biochemical of the senile brain, and that Samultang can be used to treat regressive brain disease carrying symptoms of psychoactive disorders.

This study is designed to investigate the effects of Samul-Tang extract on the response of lactic dehydrogenase(LDH) release, cellular activity, lipid peroxidation, DNA synthesis and the changes of total protein of bovine pulmonary artery endothelial cells(PAEC) from hydrogen peroxide$(H_2O_2)$-induced injury. The results are as follows : 1. Samul-Tang significantly decreased $H_2O_2$-induced release of LDH from injured bovine PAEC. 2. Samul-Tang significantly repressed $H_2O_2$-induced cellular activity from injured bovine PAEC. 3. Samul-Tang significantly repressed $H_2O_2$-induced lipid peroxidation from injured bovine PAEC. 4. Samul-Tang significantly stimulated DNA synthesis in bovine PAEC. 5. Samul-Tang significantly repressed $H_2O_2$-induced changes of total protein volume from injured bovine PAEC. Above results suggest that Samul-Tang can protect bovine PAEC from $H_2O_2$-induced injury. These results can be effectively applied to the prevention and cure of cardiovascular and cerebrovascular diseases.

Objective: This study was designed to investigate the effect of Samultang (SMT) under hippocampus cells ischemia both in vitro and in vivo. Methods: In the in vitro study, HT22 cells, predominantly detected in the cytoplasm, which coincides with the location of the mitochondria, were used as indicators. In the in vivo study, permanent middle cerebral artery occlusion (MCAO) was induced on rats. SMT was given orally 2 h before induction of permanent focal brain ischemic injury. Result: In the in vitro study, SMT had protective effects in glutamate-induced cytotoxicity, which was revealed as apoptosis characterized by chromatic condensation and the loss of mitochondrial membrane potential in HT22 cells. In the in vivo study, TTC (2,3,5-triphenyltetrazolium chloride) staining showed a marked ischemic injury in blood supply territory of the middle cerebral artery (MCA) such as the cerebral cortex and striatum. However, treatment with SMT significantly reduced infarcted volume. SMT increased marked survival of HT22 cells against glutamate-induced cytotoxicity in MTT assay. Conclusion: These results suggest that water extract of SMT provides neuroprotection against ischemic or oxidative injury by inhibition of apoptotic cell death.
