Scientific elucidation of “oketsu (blood stasis)” states is very important to understanding the diagnostic methods of oriental medicine. We investigated the correlation of blood fluidity to oketsu states, by micro channel array flow analyzer (MC-FAN). Twenty-seven female patients were divided into three groups: a non-oketsu group, a mildly affected group, and a severely affected group according to the diagnostic criteria of their oketsu syndrome. Immediately after collecting their venous blood, whole blood passage time was measured by MC-FAN. And we compared and investigated the correlation with degree of oketsu state, diagnostic criteria and changes of whole blood passage time after the administration of ku-oketsu drugs. As a result, whole-blood passage time of the mildly affected group and the severely affected group were significantly longer than that of the non-oketsu group, while the [an] improvement of blood fluidity was observed after medication. This study confirms that reduced blood fluidity is seen using MC-FAN in oketsu states, and that ku-oketsu drugs are able to improve these states.

It is well known that haloperidol is effective in the management of nausea and vomiting in cancer patients and that midazolam is used for inducing sedation in patients with delirium. Both the drugs are frequently used in a clinical setting, but there have been only few reports thus far on the concomitant administration of these 2 drugs. We report the case of a patient with massive ascites due to peritoneal carcinomatosis who had severe nausea and vomiting and went into a delirious state. This patient received a concomitant continuous infusion of haloperidol and midazolam for the management of these symptoms. Both haloperidol (up to 1.87mg/h) and midazolam (up to 1.87mg/h) were infused intravenously. For about 20 days, the nausea, vomiting and delirium were well under control without the development of any life threatening toxicities. Concomitant haloperidol and midazolam infusion was found to be a safe and effective therapy for the management of nausea and vomiting in the patient. Palliat Care Res 2009; 4(1): 312-316

Opioids are potent analgesics mostly used for severe cancer and chronic noncancer pain. However, their efficacy and safety in acute noncancer pain are debatable. We describe the case of an 82-year-old male with severe back pain due to bacteremic Staphylococcus aureus spondylitis and paravertebral abscess. Pain in such cases is usually controlled by non-steroidal anti-inflammatory drugs (NSAIDs). However, this patient was administered morphine (oral, then intravenous; up to 23 mg/day) because acetaminophen and NSAIDs did not ameliorate pain. Considerable pain relief was achieved without toxicity, and the dose of morphine was tapered through 35 days. No symptoms of addiction or withdrawal were observed during or after this 35-day period. Thus, morphine appears to be safe and effective in the management of severe, acute noncancer pain in patients with bacterial spondylitis. Palliat Care Res 2010; 5(2): 327-331

A 54-year-old woman complained of prolonged fever. Echocardiography showed severe mitral regurgitation with vegetation, and computed tomography showed right coronary artery (RCA) fistula to the coronary sinus (CS). Blood culture revealed Strep. viridans, thus a diagnosis of active infective endocarditis was established. The patient underwent urgent surgery. Surgical findings showed that vegetation was located in A3 to P3 of the mitral valve. The patient underwent mitral valve repair using a glutalualdehyde-treated autologous pericardial patch and artificial chordea. Epicardial ligation for fistula was performed. Her postoperative course was uneventful.

[Objective] Physical exercises raise more or less body temperature. A body temperature is regulated constantly generally by homeostasis mechanism. Perspiration is only heat radiation mechanism under high temperature environments. And sudoriferous water is supplied from blood. Blood flow is determined by blood fluidity, blood volume and the cardiovascular system. It was reported that strong stress decreased blood fluidity.In this experiment, we investigated the relation between blood fluidity and water supply in rats loaded with forced exercise in high temperature environment.[Methods] SPF male Wistar rats weighing 150 g were used. All animals were put in high temperature environment (Wet Bulb Globe Temperature; WBGT: 28°C) through whole experimental period. In a group of water supply, distilled water was served before and later exercise by sonde forcibly. The rats were divided into five groups randomly; Rest-Non water intake (RN), Rest-Water intake (RW), Exercise-Non water intake (EN), Exercise-Water intake (EW) and Baseline (B). The blood was collected before or later of exercise and blood fluidity or platelet aggregation was measured.[Results] In the EN, platelet aggregation, lactic acid and corticosterone increased while blood fluidity were decreased significantly compared with the RN, RW and EW. In addition, the hematocrit did not increase even if water equivalent to 8 % of body weight lost it.[Conclusion] We speculate that exercise in high temperature environment decreases blood fluidity. However, the water supply that does not completely make up for quantity of depletion in exercise may improve blood fluidity.

[Objective] Perspiration is almost only heat radiation mechanism under high temperature environments. And sudoriferous water is supplied from blood. Blood flow is determined by blood fluidity, blood volume and the cardiovascular system. It was reported that strong stress decreased blood fluidity.In this experiment, we investigated the relation between blood fluidity and water supply in rats loaded with forced exercise in high temperature environment.[Methods] SPF male Wistar rats weighing 250g were used. All animals were put in high temperature environment (Wet Bulb Globe Temperature; WBGT: 28°C) through whole experimental period. The rats were divided into four groups randomly; Suitable temperature environment-Exercise-Non water intake (SEN), High temperature environment-Exercise-Non water intake (HEN), High temperature environment-Exercise-Water intake (HEW) and Baseline (BL). In a group of water supply, distilled water was served before and later exercise by sonde forcibly. The blood was collected before or later of exercise and blood and erythrocyte suspension fluidity were measured.[Results] In the HEN, hydroperoxides, blood sodium, lactic acid and adrenaline increased while blood and erythrocyte suspension fluidity were decreased significantly compared with the BL. In addition, the hematocrit did not increase even if water equivalent to 4% of body weight lost it.[Conclusion] We speculate that exercise in high temperature environment decreases blood fluidity. However, the water supply in exercise that might not be sufficiently improve blood fluidity.

A 81-year old woman had hypertensive heart failure. She had a history of intermittent claudication for 5 years. Her ankle brachial pressure index (ABI) was 0.53 on the right and 0.58 on the left side. Coarctation of the descending aorta with severe calcification was found by a whole body CT. After medical therapy for heart failure, axillo-bifemoral artery bypass using an 8 mm ringed expanded polytetrafluoroethylene (ePTFE) graft was performed. Postoperatively, ABI improved to 0.83 on the right and 0.87 on the left side. The patient is doing well without any signs of heart failure or intermittent claudication. Although it is a palliative operation, axillo-bifemoral artery bypass is an effective and less-invasive procedure and appropriate for elderly patients.

A 44-year-old man with a history of remittent fever for 6 months was given a diagnosis of inf ective endocarditis of the aortic valve related to a congenital ventricular septal defect (VSD), although no bacterial growth was obtained by blood culture. After one week of antibiotic treatment, aortic valve replacement (AVR) and patch closure of the VSD were performed after debridement of infected tissue and vegetations involving the aortic root, pulmonary and tricuspid valves, and myocardium surrounding the VSD. Antibiotic treatment was continued postoper-atively, but elevation of C-reactive protein (CRP) persisted. Blood culture disclosed Candida albicans in the blood 3 months after AVR. Fungal prosthetic valve endocarditis (PVE) was suspected, therefore, aortic root replacement with a Free Style bioprosthesis and VSD re-closure were performed followed by continued systemic antifungal treatment. Five months after reoperation, the patient was readmitted with a high fever. A pseudoaneurysm of the left common iliac artery and complete obstruction of the external iliac artery were shown by contrast-enhanced computed tomography (CT). The aneurysm was resected without revascular-ization. This case presentation concludes that long-term whole body study with contrast-enhanced CT might be necessary even though complete eradication of the infected foci of the heart has been established.

Physicians expect nurses to be able to understand electrocardiographic (ECG) findings.However, many nurses have difficulty learning how to interpret ECGs.We suspect that the reason for such difficulty might be the nurses'mental responses to ECGs, rather than improper teaching methods.
1) We performed a questionnaire survey to investigate the mental responses to ECGs based on the responses of 197 experienced nurses and 43 new nurses and on an additional survey of 37 nurses who took ECG evaluation tests.
2) Almost all nurses recognized the necessity and importance of understanding ECG findings, and most wished to master ECGs.On the other hand, many nurses said that they disliked ECGs and did not feel competent interpreting ECGs.In particular, their perceived lack of competence in interpreting ECGs was greater than their dislike of ECGs.
3) The nurses'perceived lack of competence interpreting ECGs tended to result from feelings that developed during nursing school.Many nurses continued to have such feelings even after they began working.
4) Nurses with a poor understanding of ECGs reported many factors as being associated with their perceived lack of competence.In addition, such negative feelings toward ECGs (such as fear of making a mistake) made these nurses avoid ECGs.We believe that these feelings were likely a factor in why many nurses had difficulty mastering ECGs.
5) Nurses should be provided with appropriate ECG training that carefully considers the perceived incompetence and fear of many nurses regarding ECGs.

Yokukansan (YKS), one of the traditional Japanese “Kampo” medicines, is a mixture of extract powders from seven kinds of medicinal herbs (Atractylodis Lanceae Rhizoma, Hoelen, Cnidii Rhizoma, Uncariae Uncis Cum Ramulus, Angelicae Radix, Bupleuri Radix, and Glycyrrhizae Radix). YKS has been administered to fragile habitus patients who show symptoms such as emotional irritability, neurosis and insomnia, and to infants who suffer from night crying and convulsions. In recent years, YKS has been reported to be effective against pain disorders such as headache and chronic pain, but the mechanism underlying these beneficial effects is still unclear. In this study, the effect of YKS on chronic inflammatory pain and stress caused by pain were investigated using rats with adjuvant arthritis.
Male Wistar rats were injected with complete Freund's adjuvant into the plantar surface of the right hindpaw, and then pain thresholds and stress markers were measured. The thermal pain threshold measured with the plantar test significantly decreased, and the level of salivary chromogranin A (CgA), which is used as a mental stress marker, was significantly increased in this model. The administration of YKS controlled the activation of spinal microglia involved in the expression of chronic pain, and significantly reduced a decrease in the pain threshold. Moreover, an increase in the level of salivary CgA was significantly inhibited. The authors concluded that YKS has effects in reducing chronic inflammatory pain and the stress caused by pain.
