The authors examined the ralationship between ‘Oketsu’ syndrome and multiple cerebral infarction. In the 59 patients (62.8±9.5 years of age; 43 male and 16 female) with multiple cerebral infarction who had undergone MRI examinations, the authors evaluated the ‘Oketsu’ score, DEA (maximum diameter of the column of intravasclar erythrocyte aggregation) and erythrocyte aggregability.
The control group, 18 subjects (61.2±9.3 years of age; 11 male and 7 female) had no findings of cerebral infaction upon MRI examination.
In the patient group, the ‘Oketsu’ score was higher than the control group (P<0.0001) and microcirculation was significantly impaired (P<0.01).
According to localization of foci in the MRI study, the microcircuation was particularly impaired when infarctions occurred in areas controlled by the cortical branches (P<0.05).
Both symptomatic and asymptomatic infarctions presented high ‘Oketsu’ scores and impairment of microcirculation.
Erythrocyte aggregability significantly increased in patients in the multiple infarction symptomatic group (P<0.05). Particulaly, patients suffering from cerebral infarctions in the cortical branches had more severe erythrocyte aggregation.

The authors would like to report the successful treatment with Hochuekki-to and Keishibukuryo-gan of a case of chronic renal failure that had deteriorated rapidly in a short period of time.
The patient was a 29-year-old woman that had been diagnosed as having IgA renal syndrome in 1987 after a local physician had detected proteinuria and requested a renal biopsy. In November of the same year she came to the authors' clinic requesting Kampo therapy. After her kidney function was stabilized with such formulas as Gorei-san and Byakokaninjin-to, the patient stopped coming to the clinic. In February of 1992, she returned to the clinic with renal failure following an episode of acute pneumonia. She was admitted to the hospital due to hypertension (Cr 2.8mg/dl; BUN 20mg/dl). Dietary therapy and hypertension control were carried out, and administration of 40mg/day of prednisone (PSL) was commenced on the 10th day following admittance. Since the proteinuria remained unchanged, 1g/day of methyl-PSL was given for three days from the 18th day after admittance. However, by the 38th day (4 weeks after commencement of PSL administration) the Cr was 5.0mg/dl. At this point the Kampo formula was changed from Sairei-to to Hochuekki-to in conjunction with Keishibukuryo-gan-ka-kokadaio. Her kidney function began to improve, and by the 108th day the laboratory findings had decreased to Cr 2.7mg/dl and Bun 26mg/dl and the PSL dosage was reduced to 20mg/day. She was discharged from the hospital on the 110th day, and has been progressing well as an out-patient.

This clinical study was peformed to clarify the postoperative cardiac functions after coronary artery bypass graft surgery in the cases associated with decreased left ventricular ejection fraction (EF) or increased end-diastolic volume index (EDVI). The patients were divided into two groups by preoperative EF. The EF of Group I ranged from 31 to 39% in 42 cases, and the EF of Group II was below 30% in 27 cases. Several parameters of cardiac function such as EF, peak ejection rate (PER), peak filling rate (PFR) or early diastolic peak filling rate were evaluated with radionuclide ventriculography. Postoperative mean values of these parameters significantly improved in both Group I and Group II compared to preoperative values. Although these parameters and left ventricular wall motion did not improve in the 7 cases with an EDVI over 140ml/m² in Group II, the clinical results of these 7 cases were good during the follow-up period except one case which preoperatively had frequent ventricular arrythmia. The clinical condition improved remarkably in the 3 patients who had preoperative angina pectoris among these 7 cases. Surgical indications must be carefully determined in cases with increased EDVI and frequent ventricular arrythmia.

The therapeutic efficacy of Hachimi jio-gan on pain, weakness, numbness and coldness of the limbs and lower back was investigated in 37 aged patients. After administration for 4 weeks, improvement in the global improvement rating was 55.9%, and improvement in pain, weakness, numbness and coldness were 44.8%, 39.3%, 59.1% and 31.8%, respectively. For the improvement of numbness, more significant improvement was seen in patients 60 years old or greater than in those 59 or less. Such symptoms as hair thinning or hair loss, dimming of the eyes, constipation, pain in the upper limbs, numbness in the lower limbs, coldness of the upper limbs and coldness of the lower limbs showed significant improvement. These results suggest that Hachimi jio-gan is effective in the treatment of pain, weakness, numbness and coldness in aged patients.

Behcet's disease is generally recognized as a chronic multi-system disease. Approxymately 8% of patients with Behct's disease will have serious vascular compilcations which is called vasculo-Behcet's disease. A male patient of 41 year old was admitted to our clinic, complaining pain of left popliteal fossa and hypesthesia of left lower leg. A popliteal aneurysm was found. Resection of the aneurysm and a saphenous vein graft were successfully performed. Neuropathy disappeared after the surgery. Aneurysms in Behcet's disease mainly appear in major arteries, and rarely in peripheral arteries. Compression neuropathy in the popliteal aneurysm of Behcet's disease has been rarely reported. Early resection of aneurysm before completion of neuropathy is recommended for succsessful outcome.

A 72-year-old man was admitted with an abnormal shadow on chest X-ray. Chest CT and aortography showed double saccular aneurysms at the aortic arch and the descending thoracic aorta. Three-dimensional CT was useful to detect the association between the arch aneurysm and neck vessels. Graft replacement, from the distal arch to the descending thoracic aorta, was performed by the lateral approach with hypothermic arrest and open proximal method. The aorta had severe atherosclerotic changes and the intima was absent at the orifices of the aneurysms. Pathological examination showed the aneurysmal wall to be composed of fibrous tissue without medial components. These macroscopic and pathological findings of aneurysms corresponded with double pseudo-aneurysms originating from the penetrating atherosclerotic ulcer.

We investigated the effects of Kampo treatment on the development and progression of diabetic microangiopathy in 141 patients (95 male and 46 female patients, mean±S.D., 61.3±10.1 years) with non-insulin dependent diabetes mellitus. To this purpose, we examined the severity of diabetic microangiopathy with respect to the duration of suffering from diabetes mellitus as well as the duration of the condition after the commencement of Kampo treatment. We obtained the following results. 1) The significantly lighter the severity of diabetic nephropathy was, the longer its duration under Kampo treatment was. 2) In the group of shorter duration of suffering from diabetes mellitus, although there was no statistical significance, the longer the duration under Kampo treatment was, the lighter the severity of diabetic neuropathy and retinopathy was. But, there was no significant difference in the longer duration of suffering. It was suggested that the combination therapy with Kampo treatment was effective for diabetic microangiopathy.

Conventional footplates place physical burden on helpers due to various incidents with the footplates and the need to bend over to operate the footplate. Therefore, we examined the introduction of a semi-automated retractable footplate with a ratchet mechanism (hereafter, semi-automated retractable footrest) and investigated its safety and convenience. Both patients and staff reported that the semi-automated retractable footrest was useful. We also found that the semi-automated retractable footrest was free of incidents, reduced physical burden, and enabled helpers to avoid contamination of their hands. However, we also found aspects of the semi-automated retractable footrest that need to be improved.

OBJECTIVESDue to its industrial application and frequent use as a coating material for food containers, bisphenol A (4,4'-isopropylidenediphenol, BPA) is present in abundance in our environment. Data on intake levels of BPA are limited in preadolescent children in Japan. This study was designed to help us better understand the current state of BPA exposure in children in Japan.

METHODSWe followed first graders (n = 104) attending school in a Tokyo suburb from 1998 until the sixth grade (2003), during which time we collected a total of three morning urine samples. Urinary BPA was analyzed using high-performance liquid chromatography isotope-dilution tandem mass spectrometry.

RESULTSNinety-four children were followed for 5 years. Median urinary BPA level was 2.66 ng/mg creatinine (CRE) (range 0.9-38.9) at first grade (1998), 1.52 ng/mg CRE (0.4-11.8) at third grade (2000), and 0.66 ng/mg CRE (0.2-8.5) at sixth grade (2003), showing a significant decrease in urinary BPA levels over a 5-year follow-up study (p < 0.001). No significant difference was seen between boys and girls at each grade.

CONCLUSIONSUrinary levels of BPA were relatively low throughout the study period; however, as the study progressed, we observed a significant decline in levels, the reason behind which is not yet clear.

OBJECTIVESBisphenol A (BPA), a raw material commonly used in the manufacture of resins such as polycarbonate and epoxy, is a possible xenoestrogen that is hypothesized to disrupt the human endocrine system. Humans are widely exposed to BPA. We investigated the urinary concentration of BPA in infertile Japanese women and its possible association with endometriosis.

MATERIALS AND METHODSWe recruited 166 women (aged 20-45) who had complained of infertility and visited a university hospital in Tokyo. The subjects were interviewed and their urine samples were obtained prior to a laparoscopic diagnosis of endometriosis between January 2000 and December 2001. Urinary total BPA concentration in 140 eligible urine samples was then measured using enzymatic deconjugation of glucuronide and sulfate and high-performance liquid chromatography isotope-dilution tandem mass spectrometry.

RESULTSMedian (25th-75th percentile) unadjusted and creatinine-adjusted urinary BPA concentrations were 1.6 (0.69-2.8) μg/L and 0.80 (0.45-1.3) μg/g creatinine. No significant monotonic association of endometriosis with urinary BPA concentration was observed. Median urinary BPA concentration in women with stage 0-1 endometriosis (0.74 μg/g creatinine) did not significantly differ from that in those with stage II-IV endometriosis (0.93 μg/g creatinine) (p for difference=0.24).

CONCLUSIONSThis study, based on a larger number of samples than those in previous studies in Japan and using the most reliable analytical method currently available, showed that urinary concentrations of BPA in women who consulted a physician for infertility were not higher than those in other populations. Moreover, no association between urinary BPA concentration and endometriosis was found in this cross-sectional study.
