  • Objectives : The purpose of this study was to examine the effects of Acori Graminie Rhizoma Pharmacopuncture (PA-AG) at GV20 on cerebral ischemia-induced dementia in Mice. Methods : Mice were divided into the five following groups: normal, control, acupuncture, PA-AG (17 mg/kg), and PA-AG (34 mg/kg). All groups, except the normal group, had cerebral ischemia induced by occlusion of middle cerebral artery. The control group was not treated. The acupuncture, PA-AG (17 mg/kg), and PA-GA (34 mg/kg) groups were treated every other day with a total of 6 treatments. The effect of treatment was observed by Bax, Bcl-2, Bax/Bcl-2 ratio, cytochrome c, cresyl violet, and choline acetyltransferase staining. Results : In the PA-AG (34 mg/kg) group, the intensity of Bax was decreased and the intensity of Bcl-2 was increased. The Bax/Bcl-2 ratio also decreased in the PA-AG (34 mg/kg) group. The intensity of cytochrome c protein stain was decreased in the PA-AG (17 mg/kg) group. The density of neurons stained by cresyl violet and choline acetyltransferase (ChAT) was increased in the AT, PA-AG (17 mg/kg), and PA-AG (34 mg/kg) groups when compared with that of the control group. Conclusion : PA-AG at GV20 was effective on cerebral ischemia-induced dementia in mice.

  • The purpose of this report is to investigate the electroacupuncture effect on the cholinergic neuronal activation in the hippocampal CA1 section. The electroacupuncture was performed on S36 of white rats and its consequencies were investigated by immunohistochemical method. Hippocampal CA1 sections of Sprague Dawley white male rats electroacupunctured on S36 at 20㎐ and 100㎐ are stained by cresyl violet to show that the values of 100㎐ and 20㎐ group increased significantly compared to sham group's one. Especially, 100㎐ group shows stronger neuronal activation compared to 20㎐ group. Induction of AChE, a neurotransmitter, in hippocampal CA1 is increased significantly in 100㎐ and 20㎐ group compared to sham group. Especially 20㎐ group shows higher AChE immunoreaction than 100㎐ does, although it wasn't significant enough. Induction of NGF(Nerve Growth Factor) in hippocampal CA1 sections was observed higher in 20㎐ and 100㎐ group than in sham group. Especially, 20㎐ group shows higher NGF immunoreaction compared to 100㎐. The facts above indicate that the eletroacupucture is effect to the cholinergic neuronal activation of hippocampus induced by focal ischemia.

  • The present study was undertaken to investigate the morphological characteristics of the suprachiasmatic nucleus (SCN) of the Korean native goat by cresyl violet stain. The SCN was located ventrolateral to the third ventricle and dorsal to the optic chiasm. This nucleus was showed carrot form in longitudinal section. Its size was 1.8 mm in length, 0.9 mm in maximum height and 1.6 mm in maximum width. In coronal sections, the SCN shaped very thin plate in rostral part, but it was changed to sweet-potato form in middle part, and ornamental jade form in caudal part. The size of SCN was larger in caudal part than in rostral part. The size of the neuron of SCN was about $10{\mu}m$ in diameter with round or oval shape. The boundary of SCN was not firmly defined in caudal part because the neurons were dispersed into the hypothalamic region. It is concluded that the SCN of the Korean native goat has a morphological characteristics.

  • Current therapy for acute ischemic stroke is highly focused on neuroprotective agents, and many herbal medicines have been challenged for experimental models. The aim of this study is to investigate whether Angelicae gigantis Radix can protect nerve cells against ischemic neural damage of middle cerebral artery occlusion (MCAO) in rats' brains. Rats were treated with Angelicae gigantis Radix immediately after 2 hours of MCAO for 7 days. On the 7th day, the brains of the rats were sliced through the hippocampus and dyedby c-Fos immunohistochemistry stain and cresyl violet stain for microscopic examination. The number of viable neurons and c-Fos immunoreactive cells in CA1 regions was counted. MCAO caused significant decrease in density of neurons and c-Fos immunoreactive cells compared to those of sham-operated rats. Administration of Angelicae gigantis Radix significantly elevated MCAO-induced decrease in density of neurons and c-Fos immunoreactive cells. These results suggest that the neuroprotective effect of Angelicae gigantis Radix against focal cerebral ischemia is related to c-Fos gene expression. Thus, these findings indicate that Angelicae gigantis Radix can be used for treatment and prevention of cerebral ischemia.

  • The goal of this study is to investigate whether Uncariae Ramulus et Uncus can protect nerve cells against ischemic neuronal damage is caused by middle cerebral artery occlusion (MCAO) in rats' brains and to investigate whether the neuroprotective effect of Uncariae Ramulus et Uncus is concerned with IEGs(immediate early genes) expression. Uncariae Ramulus et Uncus(l00mg/kg) was administered immediately after 2 hours of MCAO and maintained for 7 days. On 7th days after 2 hours of MCAO, the brains of rats were sliced through the hippocampus. c-Fos immunohistochemistry stain and Cresyl violet stain were done for microscopic examination. Each number of viable neurons and c-Fos immunoreactive cells in CA1 was counted. The density of neurons and c-Fos immunoreactive cells were significantly decreased in MCAO-operated ischemic rats compared to that sham-operated rats. Administration of Uncariae Ramulus et Uncus group significantly elevated MCAO-induced decrease in density of neurons, and elevated MCAO-induced decrease in c-Fos immunoreactive cells. These results suggest that the neuroprotective effect of Uncariae Ramulus et Uncus against focal cerebral ischemia. Also, we hypothesized that neuroprotective mechanism of Uncariae Ramulus et Uncus is related to IEGs expression.

  • Objectives : It was investigated new herbal prescription HT005 supported by traditional Korean medicine has a activity on the longitudinal bone growth of rats. HT005 were consisted of the root of Angelica sinensis, the fruit of Alpinia oxyphylla, the root of Astragalus membranaceus, the stem of Eleutherococcus senticosus, and the root of Dioscorea japonica, and Poria cocos. Method : To investigate the effect on longitudinal bone growth in adolescent male Sprague-Dawley rats, the longitudinal length of growth plate was measured directly by the tetracycline fluorescent labeling method and chondrocyte staining method. HT005 administered orally for four days, and the tetracycline was injected twice on the growth plate of the animals for fluorescent dying. The rate of longitudinal bone growth was measured the length between the tetracycline bands which fixed on the 3rd day and 5th day after injection. Cresyl violet was also used to stain the chondrocytes in the growth plate. The length of growth plate after administration was compared. Expression of IGF-1 and BMP-2 in the growth plate was investigated by immunohistochemistry. Results : HT005 showed a significant longitudinal bone growth which was $301.0{\pm}6.1\;{\mu}m/day$ at the dose of 100 mg/kg and $283.8{\pm}1.25\;{\mu}m/day$ (p < 0.001)at the dose of 10 mg/kg of HT005, compared to control group by the tetracycline fluorescent labeling method. HT005 showed a significant chondrocyte length on growth plate which was measured $797.19{\pm}3.31\;{\mu}m$ (p < 0.001) at the dose of 100 mg/kg and $720.14{\pm}2.19$ (p < 0.001) ${\mu}m$ at the dose of 10 mg/kg compared to the control group by cresyl-violet staining method. Both the number and intensity of BMP-2 and IGF-1 positive cells were increased in the hypertrophic zone of growth plate. There was a significant correlation between BMP-2 and IGF-1 expression and heights of chondrocytes in growth plate. Conclusions : Treatment of HT005 on Sprague-Dawley rats markedly increased the longitudinal bone growth. Therefore, HT005 may be an alternative herbal source to growth hormone as it promotes bone growth in children afflicted by growth retardation.
