Effects of acupuncture stimulation and painful stimulation on the bone marrow circulation were studied by observing the bone marrow pressure in the femur.
Experiments were carried out on 5 adult rabbits anesthetized with urethane. Painful stimulation was given by the pinch method with a forceps.
The results obtained were as follows:
1. Immediately after the acupuncture needle was thrusted deep in the inguinal region, the bone marrow pressure of the femur of the same side showed remarkable reduction and after a few minutes, gradual rise was observed.
2. Three patterns of the rise of the bone marrow pressure were observed. First, the pressure increased monophasically and recovered to the control level. Second, the pressure rised by 7-9mmHg higher than the control value and recovered to the control level after keeping this high pressure for a few minutes. Third, after the initial fall, the pressure was regained but did not reach the control level and stayed at the lower level.
3. The stimulation to the nutrient artery with the acupuncture or the pinching caused change in the bone marrow pressure in the similar manner as the case of the acupuncture to the deep part of the inguinal region, but the stimulation on the opposite side did not cause a marked change in the pressure.
4. The painful stimulation on the inguinal region with pinching the skin reduced the pressure, but the magunitude of the reduction was smaller than those of the acupuncture stimulations given from surface to the deep part or the stimulation to the nutrient artery.
5. Stimulations on the lateral and anterior region of femur or on the opposite side produced only a slight reduction of the pressure.

Garré's osteomyelitis is generally considered to be synonymous with chronic osteomyelitis with proliferative periostitis and occurs most commonly in the first molar region of the mandible. We report a case of Garré's osteomyelitis caused by the infected tooth-germ of a wisdom tooth. A 12-year-old boy had a swelling of the right cheek and his right mandibular second molar was covered by gingiva with pus retention. X-ray examination showed a radiolucent area around the impacted tooth-germ of the wisdom tooth and extracortical new bone at the angle of the mandible. After preoperative treatment with antibiotics, the tooth-germ and extracortical bone were removed. The antibiotics treatment was continued for 18 days postoperation. No recurrence of pain or swelling has been observed thereafter.

The surface-coated vascular stent of shape memory alloy was made for use of occlusion of pseudo-lumen of the dissecting aneurysm of the aorta, as the usage of shape memory alloy in angioplasty, and the metal flexible delivery catheter was also made for the introduction of the stent. In the present study, antithrombogenicity of the vascular stent was much improved by surface-coating with EPTFE and segmented polyurethane. The long-term usage of the stent was confirmed by radiological, macroscopic, and electron microscopic examinations. Moreover, the metal flexible delivery catheter was demonstrated to be of much benefit for the introduction of the surface-coated vascular stent of shape memory alloy.

Objective : Carvedilol is a non-selective β blocker with an α blocking activity. Since this drug is highly fat-soluble, it can pass through the blood-brain barrier, and thus may induce depression and lower QOL. In the present study, physicians and pharmacists collaborated to evaluate the antihypertension effect of carvedilol and post-administration changes in QOL. Furthermore, the relationship between QOL and antihypertension effect was analyzed.
Design : Self-controlled study.
Patients and Methods : Subjects were outpatients with hypertension above the age of 70 years who visited one of 42 medical institutions in Japan between April 1995 and March 1996. A total of 243 patients were registered, and 10-20 mg of carvedilol was administered once a day for six months. Pharmacists assessed the QOL of these patients by asking 82 questions on three separate occasions : before administration and one and six months after administration. The antihypertensive effect of this drug was investigated in patients in whom all three QOL questionnaires were collected. The main test items were antihypertensive effect, changes in QOL (subjective QOL with a special emphasis on patient psychology), and the relationship between antihypertensive effect and QOL. The antihypertensive effect of this drug was statistically analyzed by a paired t-test, and changes in QOL were statistically analyzed using generalized estimating equations.
Results : All three QOL questionnaires were collected from a total of 146 patients. Their pre-administration systolic blood pressure was 159.6±1.4 mmHg, and diastolic blood pressure 94.0±0.9 mmHg, and their blood pressure decreased significantly one month after the start of administration. This antihypertensive effect of carvedilol persisted, and the systolic and diastolic blood pressure of these patients six months after the start of administration was 141.1±1.2 and 85.2±0.7 mmHg, respectively (significant decreases when compared to pre-administration levels ; both p<0.05).
Subjective QOL improved significantly after carvedilol administration. And, changes were not seen in sexual function. Changes in the five categories of subjective QOL were as follows : psychological stability, disease-induced inconvenience, and independence improved significantly after carvedilol administration, but changes were not seen in gratification or vitality. However, improvements in subjective QOL did not correlate with improvements in blood pressure.
Conclusions : The results of the present study showed that carvedilol improved QOL without negatively affecting sexual function. Subjective QOL reflects the psychological well-being of patients. In the present study, psychological stability, disease-induced inconvenience, and independence improved significantly, but changes were not seen in gratification or vitality. Since β blockers can suppress the central nervous system, they can reduce psychological stability, gratification and vitality. Even though carvedilol is highly fat-soluble, the results of non-clinical studies have shown that it does not suppress the central nervous system as much as propranolol. The results of the present study showed that carvedilol does not strongly suppress the central nervous system of humans. Moreover, significant changes in QOL were not seen between one and six months after the start of administration of carvedilol, suggesting that it is possible to estimate the QOL of patients on antihypertensive therapy after six months of administration by assessing their QOL one month after administration.

PURPOSE: Atrial natriuretic peptide (ANP) has a variety of pharmacologic effects, including natriuresis, diuresis, vasodilatation, and suppression of the renin-angiotensin system. A recent study showed that ANP infusion improved hypoxemia and pulmonary hypertension in a lung injury model. On the other hand, the pulse contour cardiac output (PiCCO(TM)) system (Pulsion Medical Systems, Munich, Germany) allows monitoring of the intravascular volume status and may be used to guide volume therapy in severe sepsis and critically ill patients. MATERIALS AND METHODS: We treated 10 pulmonary edema patients without heart disease with human ANP (HANP). The patients were divided into two groups: a group with normal Intrathoracic Blood Volume (ITBV) (900-1100 mL/m2) (n = 6), and a group with abnormal ITBV (n = 4), as measured by the PiCCOtrade mark device; the extravascular lung water (EVLW) and pulmonary vascular permeability index (PVPI) in the two groups were compared. RESULTS: The average patient age was 63.9 +/- 14.4 years. The normal ITBV group showed significant improvement of the EVLW (before, 16.7 +/- 2.7 mL/kg; after, 10.5 +/- 3.6 mL/kg; p = 0.0020) and PVPI (before, 3.2 +/- 0.3; after, 2.1 +/- 0.7; p = 0.0214) after the treatment. The abnormal ITBV group showed no significant improvement of either the EVLW (before, 16.3 +/- 8.9 mL/kg; after, 18.8 +/- 9.6 mL/kg; p = 0.8387) or PVPI (before, 2.3 +/- 0.8; after, 2.7 +/- 1.3; p = 0.2782) after the treatment. In both groups, the EVLW and PVPI were strongly correlated with the chest X-ray findings. CONCLUSION: We conclude that HANP supplementation may improve the EVLW and PVPI in pulmonary edema patients without heart disease with a normal ITBV. The PiCCO(TM) system seems to be a useful device for the management of pulmonary edema.
