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.

Objectives : Acupuncture using a tonification or sedation techniques method is used as a controlling the medication for an early stroke in the Korean medicine. LR3 has indicatons of headache, vertigo, facial paralysis, apoplexy, epiepsy as the source acupoint of a liver meridian. So this study is aims to investigate the anti-apoptotic and neuroprotective effects of acupuncture on the focal ischemia induced by intraluminal filament insertion in rats. Methods : The focal ischemia was induced by intraluminal filament insertion into middle cerebral artery. The animals were divided into seven groups (n=8 in each group) : Normal, intactness group; Conrol group, no therapy group after being ischemia induced; MA-l, acupuncture perpendicularly without Tonification or Sedation techniques at LR3 after being ischemia induced; MA-2, acupuncture obliquely towards the knee at LR3 after being ischemia induced; MA-3, acupuncture obliquely towards the toe at LR3 after being ischemia induced; MA-4, acupuncture obliquely towards the knee and rotate 9 times in a clockwise direction at LR3 after being ischemia induced; MA-5, acupuncture obliquely towards the toe and rotate 6 times in a counterclockwise direction at LR3 after being ischemia induced. The anti-apoptotic and neuroprotective effects of Acupuncture techniques of tonification or sedation at LR3 are observed by mGluR5, Bax, Cresyl violet, ChAT-stain and NGF. Results : The intensity of mGluR5 and the density of ChAT was increased in MA-1 group. The intensity of Bax was decreased in MA-3, MA-4 group. The density of neurons stained by Cresyl violet and ChAT was increased in MA-2, MA-3, MA-4, MA-5 group. The density of neurons stained by NGF was only increased in MA-4 group. Conclusions : Our study suggests that acupuncture perpendicularly without Tonification or Sedation techniques and obliquely towards the knee and rotate 9 times in a clockwise direction(Tonifying technique) at LR3 after being ischemia induced at LR3 shows anti-apoptotic and neuroprotective effects on cholinergic neuron in focal cerebral ischemia of the stroke in rats.

Aspirin (acetylsalicylic acid) is one of the most widely used therapeutic agents based on its pharmacological actions, including anti-inflammatory, analgesic, anti-pyretic, and anti-thrombotic effects. In this study, we investigated the effects of aspirin on seizure susceptibility and hippocampal neuropathology following pilocarpine-induced status epilepticus (SE). SE was induced by pilocarpine hydrochloride (280 mg/kg, i.p.) administration in C57BL/6 mice (aged 8 weeks). Aspirin was administered daily (15 mg/kg or 150 mg/kg, i.p.) for 10 days starting 3 days before SE, continuing until 6 days after SE. After pilocarpine injection, SE onset time and mortality were recorded. Neuronal cell death was examined using cresyl violet and Fluoro-Jade staining, and glial responses were observed 7 days post SE using immunohistochemistry. In the aspirin-treated group, the onset time of SE was significantly shortened and mortality was markedly increased compared to the control group. However, in this study, aspirin treatment did not affect SE-induced neuronal cell death or astroglial and microglial responses in the hippocampus. In conclusion, these results suggest that the safety of aspirin should be reevaluated in some patients, especially with neurological disorders such as temporal lobe epilepsy.

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.

Objectives : This study examined the neuroprotective effect of Hyulbuchookau-tang (血府逐瘀湯, HBCAT) against neural damage following global cerebral infarction. Methods : Sprague-Dawley rats were induced with global cerebral infarction by occlusion of the bilateral common carotid artery with hypotension (CCAO). The rats were divided into 3 groups. We treated extract of HBCAT to one group after operation (sample group), one group wasn't induced with ischemic damage after operation (sham group), and one group was induced with ischemic damage after operation (control group) but not treated. We observed neurological scores and cresyl violet-stained hippocampus CAl area, TUNEL-positive neurons, and Bax-positive neurons in brain regions. Results : HBCAT treatment after CCAO increased pyramidal neurons in CAl hippocampus induced by CCAO. HBCAT treatment after CCAO reduced Bax-positive neurons in CAl hippocampus of brain regions induced by CCAO. HBCAT treatment after CCAO wasn't effective for HSP70-positive neurons in CAl hippocampus induced by CCAO. Conclusions : These results suggest that HBCAT has a neuroprotective effect against global cerebral ischemia.
