Many ischemic disease patients have been taking herbal medicine and there are some papers that prescription of herbal medicine to ischemic disease patients are useful. Mechanism of herbal medicines on ischmeic disease have been investigated in many ways, but anticougulation or anti platelet effect of herbal medicines is not known obviously. And recently patients receiving anticougulation therapy are discouraged from taking herbal medicines. In this study, we investigate PT, INR, platelet of patients receiving herbal medicine therapy to study whether herbal medicines effect coagulation system of ischemic patients. In PT, INR, platelet values obtained from the patients, before and after administering herbal medicine, there were no significant changes.

This experiment was carried out under the postulation that activation of an intracellular calcium-calmodulin complex may play an important role in myocardial injury induced by ischemia and reperfusion. Trifluoperazine[TFP], a calmodulin antagonist, was added to the potassium cardioplegic solution and used just before ischemia, and its protective effect from ischemic injury was investigated, using Langendorff rat heart model. TFP group had better post-ischemic functional recovery and lower post-ischemic contracture after 30 minutes of normothermic ischemia. Creatine kinase leakage was also decreased in TFP group but there was no statistical difference between control group and TFP group. We concluded that TFP has some protective effect from myocardial ischemic injury and its effect might be due to prevention of activation of intracellular calcium-calmodulin complex.

This study was to examine effects of the eight month exercise program at lactate threshold level intensity on 11 women patients of ischemic heart disease. The %body fat and systolic blood pressure were decreased and the aerobic capacioties of oxygen consumption as well as oxygen consumption at lactate threshold were improved through the exercise program arranged by this study. The lipid variables concerned with coronary heart disease were changed a little except that triglyceride was significantly decreased during the exercise program. The effects obtained from exercise program during four months lasted to the end of the exercise program. In case we control the exercise intensity according to increase of oxygen consumption at lactate threshold the exercise program conducted by this study will be effective to the treatment for ischemic heart disease patients.(Korean J Nutrition 33(6) . 668~674, 2000)

This study was undertaken to investigate whether adenosine administered during cardioplegic arrest could enhance myocardial protection and improve recovery of function after ischemia. Isolated Langendorff-perfused rat hearts were subjected to 40 minutes of normothermic [37oC] ischemia. Control hearts [n=10] received modified St. Thomas’ cardioplegic solution, and the remaining hearts received modified St. Thomas’ cardioplegic solution with either 20 \ulcornerM [n=10], 200 \ulcornerM [n=10] adenosine. After ischemia of 40 minutes and 30 minutes of reperfusion, left ventricular contractility was superior in all groups of adenosine-treated hearts compared with control hearts. Furthermore, there was a significant incremental increase in functional recovery with increasing dose of adenosine. Post-ischemic diastolic stiffness was significantly better in all adenosine groups compared with controls. No differences were noted in coronary flow or myocardial water content between adenosine-treated and control hearts. These data demonstrate that adenosine administered in these concentrations provides myocardial protection, preservation of myocardial ATP and creatine phosphokinase and improved post-ischemic functional hemodynamic recovery after normothermic ischemia, presumably metabolically by reducing depletion of adenosine triphosphate, inducing rapid cardiac arrest and enabling improved post-ischemic recovery.

To investigate antioxidant status and platelet antioxidative enzyme activity in patients with ischemic heart disease, 36 male patients admitted to Kyungpook National University Hospital from June to December 1994 were compared to 36 healthy male control subjects. The percentages of heavy smoking and nonexercise were significantly higher in the patient group compared to the control, but the drinking status was not significantly different between groups. Food habit and food frequency scores were significantly lower in patients than in control subjects. Plasma retinol levels tended to be lower in the patient group, and plasma $\alpha$-tocopherol and $\beta$-carotene levels were not different between groups. There was no difference in the level of plasma thiobarbituric acid reactive substances(TBARS) and in the activities of platelet glutathione peroxidase and catalase. Our results indicate that oxidative stress, which is reflected by the plasma levels of antioxidants and TBARS, did not increase in the patients with ischemic heart disease, and the long-term effects due to smoking, poor food habit and other life styles could possibly contribute to the onset of the disease.

A 14-year-old castrated Shih Tzu weighing 5.4 kg presented with painful penile erection and dysuria that had been ongoing for 2 days. Treatment with salbutamol and gabapentin was initiated, but after 24 hours, the dog had not responded, so it was decided to proceed with penile amputation. The patient went into cardiac arrest during the surgery and died, despite attempted cardiopulmonary resuscitation. During the surgery, the penis was found to have an enlarged, tortuous, purple blood vessel located dorso-caudally to the bulbus glandis. A hemi-circular fibrous mass was found inside the vessel on histopathological examination; this mass may have induced the ischemic priapism by occluding the vein. This report describes a rare case of ischemic priapism in dogs.

Objectives : We compared with the effects of different parts (root head, root body and hairy root) of Angelica gigas Nakai (Angelicae Gigantis Radix, AG) with on middle cerebral artery occlusion(MCAO)-induced ischemic rats, and on LPS-induced inflammatory response in BV2 microglia. Methods : The 30% ethanol and water extracts of different parts of AG were prepared. Each extract (50 and 100 mg/kg) was administrated intraperitoneally once in MCAO-induced ischemic rats. We measured infarction volumes by TTC staining, and investigated the expression of iNOS, Bax, Bcl-2 and caspase-3 by Western blot. BV2 cells were treated with each extract for 30 min, and then stimulated with LPS. The levels of NO was measured by Griess assay. The expression of iNOS, Cox-2 and proinflammatory cytokines ($TNF-{\alpha}$, $IL-1{\beta}$, and IL-6) were determined RT-PCR and Western blot. The phosphorylation of ERK1/2 and JNK MAPK was determined by Western blot. Results : Among different parts of AG, the 30% ethanol and water extracts of hairy root significantly decreased infarction volume in ischemic brains and inhibited the expression of iNOS, bax and caspase-3. The extracts of hairy root significantly inhibited LPS-induced production of NO, $TNF-{\alpha}$ and IL-6 in BV2 cells, and suppressed the expression of iNOS and COX-2. The hairy root extracts attenuated LPS-induced phosphorylation of ERK1/2 and JNK MAPK in BV2 cells. Conclusions : Our results indicate that the root hairy of AG has a good neuroprotective and anti-inflammatory effects in ischemic stroke compared to other parts.

Objectives: Economic growth and development of medical technology help to improve the average life expectancy, but the western diet and rapid conversions to poor lifestyles lead an increasing risk of major chronic diseases. Coronary heart disease mortality in Korea has been on the increase, while showing a steady decline in the other industrialized countries. An age-period-cohort analysis can help understand the trends in mortality and predict the near future. Methods: We analyzed the time trends of ischemic heart disease mortality, which is on the increase, from 1985 to 2009 using an age-period-cohort model to characterize the effects of ischemic heart disease on changes in the mortality rate over time. Results: All three effects on total ischemic heart disease mortality were statistically significant. Regarding the period effect, the mortality rate was decreased slightly in 2000 to 2004, after it had continuously increased since the late 1980s that trend was similar in both sexes. The expected age effect was noticeable, starting from the mid-60's. In addition, the age effect in women was more remarkable than that in men. Women born from the early 1900s to 1925 observed an increase in ischemic heart mortality. That cohort effect showed significance only in women. Conclusions: The future cohort effect might have a lasting impact on the risk of ischemic heart disease in women with the increasing elderly population, and a national prevention policy is need to establish management of high risk by considering the age-period-cohort effect.

Objectives : To determine the contribution of cranial magnetic resonance angiography(MRA) for the evaluation of patients with ischemic cerebrovascular accident. Methods : Magnetic resonance image(MRI) and MRA studies performed on 34 patients with ischemic stroke were retrospectively reviewed with the clinical records. Results : There were 9 transient ischemic attacks and 25 completed strokes in our series. Twenty-three of 34 MRA examinations(68%) were positive for stenosis or occlusion. The distribution of stenotic or occlusive vascular lesions were correlated with the location of infarction in 22 of the 23 positive cases(96%). MRA provided additional information not obtained from the MRI in 19 cases(56%). Conclusions : Vascular lesions demonstrated on intracranial MRA show a high correlation with infarct distribution. MRA provided information adjunctive to conventional MRI in a majority of cases. We conclude that MRA is an important noninvasive component of the complete evaluation of ischemic stroke.

Purpose: This study is intended to examine the aquatic exercise on the improvement of muscle atrophy and motor function in an ischemic stroke model induced by middle cerebral artery occlusion. Methods: We used 60 Sprague-Dawely rats which were divided into 4 groups; the subjects were divided into group of 5 rats. Group I was a group of high dose aquatic exercise after inducing ischemic stroke; Group II was a group of low dose aquatic exercise after inducing ischemic stroke; Group III was a control group, Group IV was a sham group without ischemic stroke. Results: Muscle weight of gastrocnemius muscle was significantly difference in Group II compared to Group III on 8 weeks(p<0.05). For the changes in relative muscle weight of gastrocnemius muscle, there was significant increase in Group II compared to Group III on 8 weeks(p<0.05). For neurologic exercise behavior test, Group II generally had the highest score, compared to other groups. The results of behavior test that Group II improved in degeneration and inflammation of muscle fiber and decreased in destruction of nerve cells and cerebral infarction, indicating a similar state of muscle fiber and brain to Group III. Conclusion: Based on these results, aquatic exercise may improve muscle atrophy and contribute to the improvement of motor function.
