Objective : This study was undertaken to determine if Plantaginis Semen herbal acupuncture(PSA) has a protective effect on glycerol-induced acute renal failure in rats. Methods : Rats were dehydrated for 24hr and then injected with 4 ml/kg of 50% glycerol in each hindlimb muscle. In experiments for PSA effect, rats were received 0.1 ml of PSA extraction in both sides of corresponding $Sh\grave{e}nsh\bar{u}(BL_{23})$ of human body for 3 days after injection of glycerol. The experimental group were divided into the normal group, the control group, the sample 1,2,3 group. Results : Glycerol injection decreased glomerular filtration rate and increased urine volume, serum creatinine, BUN level and fractional excretion of $Na^+,\;K^+\;and\;Cl^-$. These results show that glycerol injection bring about acute renal failure. PSA significantly increased glomerular filtration rate and significantly decreased serum creatinine, BUN level and fractional excretion of $Na^+,\;and\;Cl^-$ as compared with control group. Conclusion : These results suggest that PSA can be used in prevention and treatment for acute renal failure. However, the precise mechanisms of PSA protection remain to be determined.

Objective : This study was undertaken to determine if Juglandis Semen herbal acupuncture(Ja) has a protective effect against glycerol-induced acute renal failure in rats. Methods : Rats were dehydrated for 24hr and then injected with 5 ml/kg of 50 % glycerol, one-half of dose in each hindlimb muscle. In experiments for Ja effect, rats received 0.1 ml of Ja extraction in both sides of corresponding $Sh\grave{e}nsh\bar{u}(BL_{23})$ of human body and non-acupuncture points(the root of tail) for 3 days after injection of glycerol. The experimental group were divided into the Normal group, the Control group, the Ja to $Sh\grave{e}nsh\bar{u}(BL_{23})$ group(Ja-AS), the Ja to non-acupuncture points group(Ja-AN). Results : There were significant decrease of urine volume, BUN, fractional glucose excretion, fractional phosphate excretion, total protein level in Ja-AS as compared with the control group. Conclusion : This suggests that Ja-AS could be used in prevention and treatment of acute renal failure. However, the precise mechanisms of Ja protection remain to be determined.

Objectives : The purpose of this study was to evaluate effects of taping therapy on recovery of behavioral symptoms and neural excitability of the lumbar spinal cord in rat model for ankle sprain. Methods : Adult Sprague-Dawley rats was used and divided into 3 experimental groups: normal group(n=6), ankle sprain(n=6), and ankle sprain with taping treatment(n=6). In order to induce ankle sprain the right ankle joint was injured with 4~5 repetitive over-flexions and over-extensions manually. The severity of joint pain was evaluated by measuring foot weight bearing force ratio(FWBRF) of the hind limb and the injury-induced edema formation by diameter of the joint following ankle sprain. The changes of neural excitability in the lumbar spinal cord was tested by observation of cFos protein expression, a metabolic marker for neural excitation. Results : Severity of ankle injury induced in this experiment coincided with Grade 1 ankle sprain. Compared with ankle sprain group, ankle sprain＋taping showed a significant reductions of joint pain as well as of edema formation at the ankle joint following ankle sprain. There was significant upregulation of cFos-immunoreactive neurons in the lumbar spinal cord 24 hours after ankle sprain. In contrast, taping therapy resulted in significant inhibition of cFos-immunoreactive neurons in the lumbar spinal cord. Conclusions : Collectively, these results suggest that taping therapy may be an alternative therapeutic intervention for symptom recovery of the mild ankle sprain.

Antiallergic action and the effect on normal immune function of an oriental medical prescription Gegangjochohwangsinbutang (GJHB) water extract were examined in several experimental models. GJHB water extract at 600-1,800 mg/kg/day administered orally for one week significantly recuded the passive cutaneous anaphylaxis in rats in a dose-dependent manner. Whereas the extravasation induced by intradermal leukotriene D4 in rats was significantly inhibited by GJHB water extract at 600-1,800 mg/kg/day, po, for one week, but that by histamine or serotonin was not influenced. In a rat asthma model, the delayed airway resistance in ovalbumin-induced asthmatic response was significantly attenuated by GJHB water extract of 1,800 mg/kg/day, po, administered for one week. It was also found that GJHB water extract at 1 mg/kg concentration in vitro relaxed the isolated uinea pig trachea contracted by leukotrien D4, but not that by histamine. The above findings indicate that GJHB water extract can ameliorate the adverse effect of type Ⅰ allergy such as asthma. This pharmacological action seems to derive from an inhibition of GJHB water extract on leukotriene D4-related physiological change.

The present experiment was designed to examine the effects of Jeongjihwan on carecholamines, serotonin, amino acids, lipid peroxide, free radical scavenging activity, malondialdehyde and superoxide dismutase activity in senile brain. It was performed by administering Jeongjihwan extracts of a variety of concentration to senile rats to experimentally determine effects of Jeongjihwan on biochemical changes in senile brain and examine protective effects against neurotoxin. To examine survival rate, the rat's spinal cord sensory ganglion cell pretreated in Jeongjihwan extracts was cultured in oxygen free radical. The results were summarized as follows: 1. Jeongjihwan significantly increased noradrenaline in the hippocampus and hypothalamus of the brain tissue of senile rats, and even though Jeongjihwan increased noradrenaline also in other brain tissue, there was no significance. 2. Jeongjihwan had no effects on dopamine changes in all brain tissue of senile rats. 3. Jeongjihwan significantly increased serotonin, but decreased in other brain tissue. 4. Jeongjihwan increased amino acid in the brain tissue of senile rats. 5. Jeongjihwan significantly decreased lipid peroxide and free radical in the brain tissue of senile rats. 6. Jeongjihwan significantly increased survival rate of nerve cell exposed to oxygen free radical. According to the above results, Jeongjihwan is assumed to improve brain function by reacting on biochemical changes of the senile brain and carries effects of protecting against neurocytotoxicity, and that Jeongjihwan can be used to treat regressive brain disease carrying symptoms of psychoactive disorders.

Reactive oxygen species (ROS) have been suggested to be contributory factors in complications of diabetes mellitus. In the present study, we investigated the generation of superoxide, the lipid peroxide level measured as thiobarbituric acid reactive substances, the vasorelaxation of isolated thoracic aorta and the iNOS expression in kidney of streptozotocin induced diabetic rats. Sprague Dawley rats were divided into four groups: control, ascorbate (400 mg/kg rat weight daily in drinking water), diabetic (single dose of 50 mg of STZ/kg i.p.) and diabetic simultaneously fed with ascorbate for 12 wk. Rats in groups were studied at tri-weekly intervals (0 to 12 wk). Diabetic rats were evaluated periodically with changes of plasma glucose levels and body weight. The ascorbate supplimentation attenuated the development of hyperglycemia and weight loss induced by STZ injection in rats. In the present experimental condition, the ascorbate supplimentation had no significant effect on plasma glucose levels and changes in body weight of normal rate. The superoxide generation, formation of thiobarbituric acid reactive substance and iNOS expression in kidney were significantly increased in STZ-treated rats that were decreased by ascorbate supplimentation. The ascorbate supplimentation had no effect on vasorelaxation of isolated thoracic aorta. These results indicate that ascorbate supplimentation may exert an inhibitory effect on STZ-induced oxidative tissue damage through protection of pancreatic islet cells by scavanging reactive oxygen species. The ascorbate supplimentation may possibly attenuate the renal complication of diabetes mellitus.

본 실험은 식이중에 첨가된 coenzyme Q10이 adriamycin (ADR)을 투여한 흰쥐의 심근 미세 구조에 미치는 영향을 규명하기 위하여 실시되었다. 실험군은 모두 ADR 2수준(1.0mg/kg B.W./week, 2.0mg/kg B.W./week)과 coenzyme Q10 3수준(무첨가군, 0.1g / kg diet 및 0.5g / kg diet)에 의한 6개의 실험군과 basal diet만을 공급하는 대조군을 설정하였다. 체중증가량은 ADR의 투여수준이 높을수록 유의적으로 감소되었으며 식이효율에 있어서는 고수준의 ADR 투여시에만 대조군에 비하여 감소되었다. 그러나 coenzyme Q10에 의한 회복효과는 나타나지 않았다. 혈장내 CPK 활성도는 ADR투여로 약간 증가되었으나 유의적인 차이는 없었으며 coenzyme Q10 급여에 대한 영향은 나타나지 않았다. 전자현미경을 통해 심장조직의 형태적변화를 살펴본 결과 ADR투여로 인해 심근세포내 미세구조의 변성을 관찰할 수 있었고 특히 mitochondria 의 변형, myofibil을 비롯한 세포 소기관의 소실 및 파괴로 빈 공간이 형성되어 있었으나 coenzyme Q10 급여군에서는 그 정도가 약화되었다. 고수준의 ADR 투여는 mitochondria 의 volume density와 surface density를 크게 감소시켰지만 고수준의 coenzyme Q10 급여에 의해 이러한 감소가 조절되었다.

Ginseng is one of the most widely used medicinal plants, particularly in East Asian countries. Certain fractions or purified ingredients of ginseng have been shown to exert inhibitory effects on growth of cancer cells in culture or on tumorigenesis in experimental animals. Moreover, a recent epidemiologic study reveals that ginseng intake is associated with a reduced risk for environmentally related cancers such as esophageal, gastric, colorectal, and pulmonary tumors. Heat treatment of Panax ginseng C. A. Meyer at the temperature higher than that applied to the conventional preparation of red ginseng yielded a mixture of saponins with potent antioxidative properties. Thus, the methanol extract of heat-processed ginseng (designated as'NGMe') attenuated lipid peroxidation in rat brain homogenates induced by ferric ion or ferric ion plus ascorbic acid. Furthermore, the extract protected against strand scission in f Xl 74 supercoiled DNA Induced by UV photolysis of H2O2 and was also capable of scavenging superoxide generated in vitro by xanthine/xanthine oxidate or in differentiated human promyelocytic leukemia (HL-60) cells by the tumor promoter,12-0-tetvade- canoylphorbol-13-acetate (TPA). Since tumor promotion is closely linked to oxidative stress, we have determined possible anti-tumor promotional effects of NGMe on two-stage mouse skin tumorigenesis. Topical application of NGMe onto shaven backs of female ICR mice 10 min prior to TPA significantly ameliorated skin papillomagenesi s initiated by 7,12-dimethylbenz (a) anthracene (DMBA).'Likewise, TPA-induced epidermal ornithine decarboxylase activity and elevation of tumor necrosis factor-a were suppressed signifies%fly by NGMe pretreatment. NGMe topically applied onto surface of hamster buccal pouch 10 min before each topical application of DMBA inhibited oral carcinogenesis by 76olo in terms of multiplicity. Taken together, these results suggest that processed Panax ginseng C. A. Meyer has potential cancer chemopreventive activities.
