  • 본 연구는 농도를 달리한 알루미늄 급여가 두충의 효과에 미치는 영향을 실시한 결과 식이섭취량에서 두충차 추출액과 알루미늄 병합급여군은 알루미늄 단독급여군에 비하여 증가하였으나 각 실험군간에 유의성은 나타나지 않았다. 음용수 섭취량은 알루미늄 단독 급여군에 비하여 알루미늄과 두충차 추출액 병합급여군이 약간 증가하였다. 체중 증가량은 대조군과 두충차 추출액 급여군에 비하여 농도를 달리한 알루미늄 급여군이 감소하였으며 식이효율은 각 실험군간에 유의적인 차이는 나타나지 않았다. 간, 심장, 신장, 폐, 위, 소장, 대장 및 비장 조직 중의 알루미늄 함량에서 대조군과 두충차추출액급여군 간에는 별다른 차이를 보이지 않았으나 각각의 농도를 달리한 알루미늄 급여군에 비하여 알루미늄과 두충차 추출액 병합급여군의 함량은 감소하였다. 레닌활성도에서 대조군에 비하여 두충차 추출액 급여군이 감소하였고, 각각 농도를 달리한 알루미늄 급여군에 비하여 알루미늄과 두충차 추출액 병합급여군이 유의적으로 감소하였다. 알도스테론농도는 각각 농도를 달리한 알루미늄 급여군에 비하여 알루미늄과 두충 추출액 병합급여군이 유의적으로 감소하였다. ALT와 AST는 농도를 달리한 알루미늄 단독 급여군에 비하여 알루미늄과 두충차 추출액 병합 급여군이 유의적으로 감소하였다. LDHase는 알루미늄 급여군에 비하여 알루미늄과 두충차 추출액 병합급여군이 감소하였으나 유의한 차이는 없었다. ChEase는 농도를 달리한 알루미늄 단독급여군에 비하여 두충차 추출액과 알루미늄 병합급여군 및 대조군과 두충차 추출액군이 유의하게 증가하였다. 따라서 알루미늄을 만성적으로 섭취하게 되면 독성효과를 나타낼 수 있으나 두충차추출액이 알루미늄에 의해 손상된 조직과 AST, ALT, LDHase. ChEase 활성도, 레닌, 알도스테론 호르몬 농도에 어느정도 영향을 미치는 것으로 나타나 두충의 폴리페놀 성분이 알루미늄에 의한 어느 정도 중독 완화 효과가 있으며, 본 실험은 흰쥐를 이용한 동물모델로 실시하였으나 알루미늄은 여러 경로를 통해 사람에게 노출 될 수 있으므로 알루미늄이 인체에 어떤 영향을 미치는지에 대한 연구는 계속되어져야 한다고 사료된다.

  • This studt was investigated to prove the effect of SPBST on the hypertension, the thrombosis and the brain damage. The results were as follows; 1. SPBST affected the htpertension as adepressant, but insignificant. 2. SPBST decreased significantly dopamine, aldosterone but ineffective on the epinephrine, norepinephrine and renin activity. 3. SPBST increased the NO product but insignificant. 4. SPBST had a death suppression effect by 50% in pulmonary thrombosis inducement experiment and activated slightly on the fibrinolytic activity. 5. SPBST suppressed significantly platelet diminution and prolonged insignificantly PT and APTT. 6. On the measure of the blood flow rate induced by the thrombus, in vivo SPBST accelerated the blood flow rate, in vitro insignificant. 7. SPBST had no toxicity on the PC12 cell and B103 cell induced by amyloid β protein (-35) and a protective effect, in proportion to the density. 8. SPBST decreased significantly coma duration time in a Infatal dose of KCN and showed 50% of survival rate in a fatal dose. 9. SPBST decreased significantly ischemic area and edema incited by the MCA blood flow block. These results indicate that SPBST can be used in hypertension, the thrombosis, the brain damage, the ischemic cerebral infarction and the acute stage of the brain damage. Further study will be needed about the functional mechanism and etc.

  • Purpose: Alterations in the structure and function of vascular smooth muscle cells (VSMCs) are important in cardiovascular disease and maintaining chronic hypertension. Chronic hypertension is associated with changes in vascular smooth muscle tone. The spontaneous or myogenic tone of a blood vessel reflects the ability to adapt smooth muscle tone to changes in transmural pressure. However, the intracellular signaling mechanisms involved in myogenic tone are not fully understood. Methods: Here, we investigated the relationship between mitogen-activated protein kinases (MAPKs) and phosphatidylinositol-3 kinase (PI3K) in isometric contraction and enzymatic activity using muscle strips from rats made hypertensive with aldosterone-analogue deoxycorticosterone acetate (DOCA) salts. Results: Changes in myogenic tone and intracellular $Ca^{2+}$ concentration ($[Ca^{2+}]_i$) were different after physiological salt solution (PSS) in normotensive and hypertensive rats. The myogenic tone and quiescent phosphorylation induced by the PSS treatment were inhibited by 10 ${\mu}$M PD098059, an extracellular-regulated protein kinase 1/2 (ERK1/2) inhibitor, and 10 ${\mu}$M wortmannin, an inhibitor of PI3K, in hypertensive rats. Conclusion: The development of DOCA-induced hypertension is associated with altered isometric contractions and $[Ca^{2+}]_i$ via changes in activation of ERK1/2 and PI3K after DOCA-salt treatment. Therefore, ERK1/2 and PI3K activity affect hypertension and may be suitable targets for physical therapy in cardiovascular disease.

  • It was our working hypothesis that introduction of 11-keto groups to 12-oleanene/ursene series of triterpenoids should endow them with corticoid-like activities, since pharmacological actions of glycyrrhetinic acid (GA) are known to be caused by inhibition on $corticoid-{\delta}^4-reductase$. 11-Keto-triterpenoids derived artificially in these studies, such as 11, 19-diketo-18, 19-secoursolic acid methyl ester(I), $11-keto-{\beta}-boswellic$ acid derivatives (IIa-IIc), 11-Keto-presenegenin dimethyl ester (III), II-keto-oleanolic acid derivatives (IVa-IVd) and 11-keto-hederagenin (V) possess the fundamental functions of ${\alpha},\;{\beta}-unsaturated$ ketone on C-11 and hydroxyl group on C-3, as like GA (VI). Additionally, they involve the carboxyl groups on rings A (II, III), D (I, III, IV, V) and E (VI), and the hydroxyl groups on rings A (III, V) and C (III). All the compounds competitively inhibited $corticoid-5{\beta}-reductase$, and the highest inhibitory potency appeared in I. All of them except $3,\;11-diketo-{\beta}-boswellic$ acid methyl ester (IIc) were more effective about five times to twice than GA. On carrageenin-induced edema test, compounds I and IVa-IVd showed anti-inflammatory activities, but III enhanced rather edema. Structure-activity relations were found in the aspects of hydrophilicity of ring A and hydrophobicity of rings C/D. The more they were hydrophilic in ring A and hydrophobic in rings C/D, the more they inhibited the enzyme. And the more they were hydrophobic in rings C/D, the more they exhibited antiiflammatory activities. However, the increased hydrophilicity in ring A resulted in increasing edema, probably due to a nonspecific inhibition on $aldosterone-5{\beta}-reductase$.

  • Kamigingansikpung-tang(KGST) has been used for many years as a therapeutic agent for acute stage of cerebrovascular disease and hypertension in oriental medicine. But the effect of KGST on hypertension and vascular system is not well-known. This study was done to investigate the effects of KGST on hypertension. The results were obtained as follow: KGST showed scavenging activity on DPPH free radical. KGST showed the inhibitory effect on ROS and ACE, and the accelerated SOD activity. KGST significantly decreased the blood pressure and pulse in DOCA-salt induced hypertensive rat. KGST significantly decreased the levels of aldosterone in DOCA-salt induced hypertensive rat. KGST significantly decreased the levels of dopamine, epinephrine in DOCA-salt induced hypertensive rat. KGST significantly decreased the levels of potassium(K+) and chloride(Cl-) in DOCA-salt induced hypertensive rat. KGST significantly decreased the levels of uric acid and creatine in DOCA-salt induced hypertensive rat. KGST has an effect on inhibiting cell damage of the heart, liver, kidney, and adrenal gland. results suggest that KGST might be effective in treatment and prevention of hypertension.

  • The purpose of the investigation was to establish how the pineal-adrenal axis plays an important role in thermoregulation in female goats under short-term heat stress. The study was conducted to observe the influence of glucocorticoids on pineal function in goats and its influence on stress alleviation capability. Melatonin and glucocorticoid secretions and several other endocrine and biochemical blood parameters reflecting the animals well being were determined over a one week period after goats had been exposed to $40^{\circ}C$ and 60% relative humidity for 10 days. Six female goats were used in the study. These animals served as self controls prior to the start of the experiment. The study was conducted for a period of seventeen days in a psychrometric chamber at $40^{\circ}C$ and 60% relative humidity. Chemical pinealectomy was achieved using propranolol followed by exogenous hydrocortisone treatment. Blood samples were drawn twice daily after each treatment to find the effect of hydrocortisone on plasma glucose, total protein, total cholesterol, cortisol, insulin, aldosterone, melatonin and corticosterone. Chemical pinealectomy significantly ($p{\leq}0.05$) affected plasma levels of the parameters studied and these could be significantly ($p{\leq}0.05$) counteracted by administration of hydrocortisone. Chemical pinealectomy aggravated thermal stress, although administration of hydrocortisone could ameliorate the condition. This indicated a role of the pineal in support of thermoregulation. The study establishes the modulating effect of glucocorticoids on pineal activity to relieve thermal stress in goats.

  • 1. Objectives This is a case of refractory ascites due to hepatocellular carcinoma treated with Sasang Constitutional Medication. Refractory ascites, which did not respond to diuretics, was improved with Jeoryeongchajeonja-tang. 2. Methods We recorded the patient's abdominal circumference, body weight and urine output daily. We also investigated the TTKG(transtubular potassium gradient) values 3 times during the treatment course. 3. Results the TTKG value of the patient was siginificantly decreased. TTKG values before administration of Jeotyeongchajeonja-tang were 8.41, 10.82, respectively and 4.25 after administration of Jeotyeongchajeonja-tang. 4. Conclusions We guess that Jeoryeongchajeonja-tang functions as an aldosterone antagonist or increases spironolactone activity through interaction between Jeotyeongchajeonja-tang and spironolactone. But the mechanism of Jeotyeongchajeonja-tang is not clear, so we need more clinical study of refractory ascites improved with Jeotyeongchajeonja-tang and biological study of interaction between Jeotyeongchajeonja-tang and spironolactone.

  • The aim of this experiment was to elucidate the effects of Saseuptang water extract on the renal function plasma renin activity and plasma levels of atrial natriuretic peptide and aldosterone in rat The results were as follows; 1. Water balance decreased significantly after the administration of Saseuptang water extract, 0.4 and 0.8ml/kg. 2. Urine volume increased significantly after the administration of Saseuptang water extract, $0.4\;m{\ell}/kg$. 3. Urinary excretion of chloride increased significantly after the administration of Saseupthang water extract, $0.8\;m{\ell}/kg$. 4. Free water clearance increased significantly after the administration of Saseuptang water extract, $0.8\;m{\ell}/kg$. 5. Urinary excretion of creatinine increased significantly after the administration of Saseuptang water extract, $0.8\;m{\ell}/kg$. 6. Plasma levels of atrial natriuretic peptide (ANP) decreased significantly after administration of Saseupthang water extract, $0.8\;m{\ell}/kg$. These results suggest that the changes of urine volume after the administration of Saseuptang water extracts are related to the increments of glomerular filtration rate and free water clearance, and it is suggested that the changes of renal function by which Saseuotang may related to the renin-angiotensin and atrial natriuretic peptide system.
