Abstract
Brain-derived neurotrophic factor (BDNF) plays an important role in neurogenesis, synaptic plasticity, and cognition. BDNF is a neurotrophin that binds to tropomyosin receptor kinase B (TrkB), a specific receptor on target cell surfaces; it acts on neuronal formation, development, growth, and repair via transcription factors, such as cAMP response element-binding protein (CREB), and it is involved in learning and memory. BDNF expression is decreased in patients with Alzheimer's disease (AD). Exercise and the intake of several different foods or ingredients can increase BDNF expression, as confirmed with lutein, xanthophylls (polar carotenoids), and ethanolamine plasmalogen (PlsEtn), which are present at high levels in the brain. This study examined the effects of combining lutein and PlsEtn using lutein-rich Chlorella and ascidian extracts containing high levels of PlsEtn bearing docosahexaenoic acid, which is abundant in the human brain, on the activation of the BDNF-TrkB-CREB signaling pathway in the hippocampus of Sprague-Dawley rats. Although activation of the BDNF-TrkB-CREB signaling pathway in the hippocampus was not observed in Chlorella or ascidian PlsEtn monotherapy, activation was observed with combination therapy at an equal dose. The results of this study suggest that the combination of Chlorella and ascidian PlsEtn may have a preventive effect against dementia, including AD.

Abstract
Non-alcoholic fatty liver disease is a common liver disease worldwide, and is associated with dysregulation of lipid metabolism, leading to inflammation and fibrosis. Acanthopanax senticosus Harms (ASH) is widely used in traditional medicine as an adaptogen food. We examined the effect of ASH on steatohepatitis using a high-fat diet mouse model. Mice were fed a choline-deficient, L-amino acid-defined, high-fat diet with ASH extract (ASHE). After 6 weeks, liver RNA transcriptome sequencing (RNA-Seq) was performed, followed by Ingenuity Pathway Analysis (IPA). Our findings revealed that mice fed a high-fat diet with 5% ASHE exhibited significantly reduced liver steatosis. These mice also demonstrated alleviated inflammation and reduced fibrosis in the liver. IPA of RNA-Seq indicated that hepatocyte nuclear factor 4 alpha (HNF4 alpha), a transcription factor, was the activated upstream regulator (P-value 0.00155, z score = 2.413) in the liver of ASHE-fed mice. Adenosine triphosphate binding cassette transporter 8 and carboxylesterase 2, downstream targets of HNF4 alpha pathway, were upregulated. Finally, ASHE-treated HepG2 cells exposed to palmitate exhibited significantly decreased lipid droplet contents. Our study provides that ASHE can activate HNF4 alpha pathway and promote fat secretion from hepatocytes, thereby serving as a prophylactic treatment for steatohepatitis in mice.

Abstract
Plant-derived polar lipids have been reported to exhibit various beneficial effects on human health. The green alga Chlorella is known to be abundant in nutrients, including lipophilic components, and has varying nutrient content depending on the strain. In this study, to assess the nutritional functions of the strain Chlorella pyrenoidosa, we comprehensively analyzed the composition of fatty acids, polar glycerolipids, and sphingolipids. We found that n-3 polyunsaturated fatty acids (PUFAs) comprised 45.6 mol% of fatty acids in the total lipids and 62.2 mol% of n-3 PUFAs in the total lipids occurred in the glycolipids. Monogalactosyldiacylglycerol was the primary glycolipid class, and n-3 PUFA constituted 73.5 mol% of the fatty acids. Although glucosylceramide was observed in trace amounts, highly polar sphingolipids (HPSs), including glycosyl inositol phosphoryl ceramide, were found in much higher amounts compared to rice bran, which is a common source of sphingolipids. These results suggest that the examined Chlorella strain, which is abundant in glycolipids bearing n-3 PUFAs and HPS, is potentially useful as a dietary supplement for improving human health.

Abstract
Acanthopanax senticosus (Rupr. et Maxim) Harms (ASH), also known as Siberian ginseng or eleuthero, is a hardy shrub native to China, Korea, Russia and the northern region of Japan. ASH is used for the treatment of several diseases such as heart disease, hypertension, rheumatoid arthritis, allergies, chronic bronchitis, diabetes and cancer. In the present study, the inhibitory effect of the root extract of ASH (ASHE) on HuH-7 and HepG2 liver cancer cells was examined. ASHE suppressed liver cancer cell proliferation by inducing cell cycle arrest at the G0/G1 phase, as well as apoptosis, as indicated by the increased number of Annexin V and 7-AAD-positive cells. Furthermore, the expression of LC3-II, an autophagy marker, in these cells also increased post treatment with ASHE. LC3-II induction was further enhanced by co-treatment with chloroquine. Fluorescence and transmission electron micrographs of ASHE-treated liver cancer cells showed the presence of an increased number of autophagic vesicles. A decreased protein expression level of run domain Beclin-1-interacting and cysteine-rich domain-containing, an autophagy inhibitor, with no change in RUBCN mRNA expression was observed, indicating activation of the autophagosome-lysosome fusion step of autophagy. In conclusion, ASHE exerts cytostatic activity on liver cancer cells via both apoptosis and autophagy, and may serve as a potential therapeutic agent for management of liver cancer and autophagy-related diseases.

Abstract
Mental stress, such as anxiety and conflict, causes physiological changes such as dysregulation of autonomic nervous activity, depression, and gastric ulcers. It also induces glucocorticoid production and changes in hippocampal brain-derived neurotrophic factor (BDNF) levels. We previously reported that Acanthopanax senticosus HARMS (ASH) exhibited anxiolytic activity. Thus, we attempted to identify the anxiolytic constituents of ASH and investigated its influence on hippocampal BDNF protein expression in male Sprague Dawley rats administered chlorogenic acid (CHA), ( +)-syringaresinol-di-O-β-D-glucoside (SYG), or a mixture of both (Mix) for 1 week using the open field test (OFT) and improved elevated beam walking (IEBW) test. As with ASH and the benzodiazepine anxiolytic cloxazolam (CLO), Mix treatment significantly increased locomotor activity in the OFT. CHA and Mix increased the time spent in the open arm in the IEBW test. SYG and Mix treatment inhibited the significant increase in normalized low-frequency power, indicative of sympathetic nervous activity, and significant decrease in normalized high-frequency power, indicative of parasympathetic nervous activity, as observed in the IEBW test. SYG and Mix treatment significantly increased hippocampal BDNF protein expression. The combination of CHA and SYG possibly induces anxiolytic behavior and modulates autonomic regulation, activates hippocampal BDNF signaling as with ASH.

Abstract
Mental stress, such as anxiety and conflict, causes physiological changes, such as changes in autonomic nervous activity and gastric ulcers. In addition, stress induces glucocorticoids and changes the hippocampal brain-derived neurotrophic factor (BDNF) expression levels. We previously reported that Acanthopanax senticosus HARM (ASH) prevents stress-induced gastric ulcers. Thus, we investigated the potential anxiolytic effect and influence of ASH on the hippocampus BDNF-related protein in male Sprague-Dawley rats fed 1% and 5% ASH extract-containing food for one week using novelty suppressed feeding (NSF) and improved elevated beam walking (IEBW) tests. ASH treatment significantly decreased latency to eat in the NSF test and increased the time spent on the open arm in the IEBW test. ASH5% treatment showed a significant decrease in LFnu, indicative of sympathetic nervous activity, and a significant increase in HFnu, indicative of parasympathetic nervous activity, in the NSF test. In addition, ASH1% and ASH5% treatments significantly decreased LFnu and significantly increased HFnu in the IEBW test. ASH5% treatment significantly increased hippocampal BDNF protein expression in both Western blotting and immunohistochemistry experiments. Our findings suggest that anxiolytic effects of ASH occur via the regulation of autonomic function and increased hippocampal BDNF signaling.

Abstract
Accumulation of phospholipid hydroperoxide (PLOOH) in erythrocyte membranes is an abnormality found in patients with senile dementia, including those with Alzheimer's disease. In our previous studies, dietary xanthophylls (polar carotenoids such as lutein) were hypothesized to inhibit lipid peroxidation. In the present study, we conducted a randomized, double-blind, placebo-controlled human trial to assess the impact for a total of 2 months Chlorella supplementation (8 g Chlorella/day/person; equivalent to 22.9 mg lutein/day/person) on PLOOH and carotenoid concentrations in erythrocytes as well as plasma of 12 normal senior subjects. After 1 or 2 months of treatment, erythrocytes and plasma lutein concentrations increased in the Chlorella group but not in the placebo group. In the Chlorella-supplemented group, erythrocyte PLOOH concentrations after a total of 2 months of treatment were lower than the concentrations before supplementation. These results suggest that Chlorella ingestion improved erythrocyte antioxidant status and lowered PLOOH concentrations. These reductions might contribute to maintaining the normal function of erythrocytes and prevent the development of senile dementia.

Abstract
With the improved survival rate of patients with retinoblastoma, the incidence of second malignancies has become substantial. We had two retinoblastoma survivors with secondary malignancies in the naso-ethmoidal complex, one a 21-year-old man with anaplastic carcinoma and the other a 16-year-old girl with malignant fibrous histiocytoma. They underwent repeated craniofacial surgery. Secondary malignancies arising at the nose and ethmoidal cells often invade the anterior skull base. The introduction of skull base surgery has provided wider surgical margins and increased the resultant likelihood of cure. Both patients have so far shown no evidence of recurrence.

Abstract
Pregnancy anemia and pregnancy-induced hypertension (PIH) are common and potentially dangerous disorder in human pregnancy, and nutritional status of pregnant women is one of the leading causes. Chlorella contains large quantities of folate, vitamin B-12 and iron, and can help improve anemia and hypertensive disorder. Our objective was to investigate the preventive effects of Chlorella supplement on pregnancy anemia and PIH in Japanese pregnant women. A total of 70 pregnant women were placed into the control group (n = 38) or the Chlorella group (n = 32). The subjects in the Chlorella group were supplemented daily from 12th-18th wk of gestation until delivery with 6 g of Chlorella supplement. The proportion of anemic (hemoglobin level < 11 g/dL) subjects in the Chlorella group were significantly lower compared with the control group at the second and third trimesters. Additionally, in the Chlorella group, the incidences of proteinuria and edema, signs of PIH, were significantly lower during the third trimester. These results suggest that Chlorella supplementation significantly reduces the risk of pregnancy associated anemia, proteinuria and edema. Chlorella supplement may be useful as a resource of natural folate, vitamin B-12 and iron for pregnant women.

Abstract
A Chlorella powder was tested in a total of 129 in vitro receptor binding assay systems. The results showed a potent inhibition of this powder on cysteinyl leukotriene CysLT2, and glutamate AMPA in a dose-concentration manner with IC(50) mean +/- SEM values of 20 +/- 4.5 microg/mL and 44 +/- 14 microg/mL, respectively. Other moderate and weak activities reflected in competitive binding experiments were seen versus adenosine transporter; calcium channel L-type, benzothiazepine; gabapentin; kainate, NMDA-glycine; inositol trisphosphate IP(3); cysteinyl CysLT(1), LTB(4); purinergic P(2Y); tachykinin NK(2); serotonin 5-HT(2B) and prostanoid, thromboxane A(2). Together, the results suggest that the various inhibitory effects of Chlorella powder in these receptor binding assays could reflect its actions in modulating Ca(2+)-dependent signal related targets and might be relevant to the mechanisms of its biological effects. These results reveal important potential biochemical activities that might be exploited for the prevention or treatment of several pathologies. From these results, the possible therapeutic usage of the product is discussed.

Abstract
In addition to meeting nutritional requirements, breast milk plays important roles in biodefense for nursing infants. Dioxins have been detected at high concentrations in breast milk, raising concerns about disorders in nursing infants caused by breast milk containing dioxins in Japan. We analyzed dioxin levels in breast milk and maternal blood samples from 35 pregnant women in Japan. We also measured immunoglobulin (Ig) A concentrations in breast milk and investigated correlations with dioxin concentrations. In addition, 18 of the 35 women took Chlorella pyrenoidosa (Chlorella) supplements during pregnancy, and the effects on dioxin and IgA concentrations in breast milk were investigated. Toxic equivalents were significantly lower in the breast milk of women taking Chlorella tablets than in the Control group (P = .003). These results suggest that Chlorella supplementation by the mother may reduce transfer of dioxins to the child through breast milk. No significant correlation was identified between dioxin and IgA concentrations in breast milk in the Control group. It is unlikely that normal levels of dioxin exposure via food have a remarkable influence on IgA in breast milk. IgA concentrations in breast milk in the Chlorella group were significantly higher than in the Control group (P = .03). Increasing IgA levels in breast milk is considered to be effective for reducing the risk of infection in nursing infants. The present results suggest that Chlorella supplementation not only reduces dioxin levels in breast milk, but may also have beneficial effects on nursing infants by increasing IgA levels in breast milk.

Abstract
Dioxins can be transferred from mother to fetus via the placenta, or to nursing infants via breast milk, potentially causing developmental health problems in children. To assess pediatric health risks from dioxins, exposure of mothers and children to dioxins must be clarified. Methods of reducing maternal transfer of dioxins should also be investigated. Concentrations of 28 dioxin (polychlorinated dibenzo-p-dioxins, polychlorinated dibenzofurans, and co-planar polychlorinated biphenyls) congeners in blood, adipose tissue, breast milk, cord blood and placenta collected from 44 pregnant Japanese women were measured. In addition, to investigate potential reductions in maternal transfer of dioxins, 23 pregnant women were instructed to take Chlorella pyrenoidosa supplements during pregnancy. Correlations were observed between dioxin total toxic equivalents (total TEQ) in blood and total TEQ in adipose tissue (r=0.913, P<0.0001), breast milk (r=0.695, P=0.0007), and cord blood (r=0.759, P<0.0001). Dioxin levels transferred to fetuses and nursing infants reflect cumulative maternal concentrations of dioxins. A linear regression equation was introduced to predict total TEQ in breast milk and cord blood from dioxin levels in maternal blood, which should prove useful in evaluating fetal and infant risk of dioxin exposure. Total TEQ in cord blood were approximately 26% lower than in maternal blood (P<0.0001). The results of this study suggest that transplacental transfer differs depending on the dioxin congener. Total TEQ in breast milk were approximately 30% lower in the Chlorella group than in controls (P=0.0113). This finding suggests that maternal transfer of dioxins can be reduced using dietary measures such as Chlorella supplements.

Abstract
The modifying effects of dietary administration of dried Chlorella pyrenoidosa powder (C. pyrenoidosa) on the development of glutathione S-transferase placental form-positive foci (GST-P-positive foci), which are putative preneoplastic lesions, in male F344 rats were investigated using a medium-term liver bioassay system. In rats given 10% C. pyrenoidosa in a basal diet, the number and area of GST-P-positive foci in the rat livers, which diethylnitrosamine (DEN) initiated and 2-amino-3,8-dimethylimidazo[4,5-f] quinoxaline (MeIQx) promoted, were significantly decreased compared with those fed a basal diet not containing C. pyrenoidosa. The inhibition percentage of the number and area of GST-P-positive foci > or =0.2 mm in diameter was 67.6 and 74.2%, respectively (p<0.01). Furthermore, C. pyrenoidosa significantly decreased the number of GST-P-positive foci induced by MeIQx alone. The inhibition percentage of the number of GST-P-positive foci <0.2 mm in diameter was 52% (p<0.01). These results suggest that C. pyrenoidosa has chemopreventive effects against hepatocarcinogenesis in rats. C. pyrenoidosa appears to be a promising chemopreventive agent for human liver neoplasia and carcinogenesis induced by heterocyclic amines such as MeIQx.

Abstract
The effect of Chlorella pyrenoidosa on fecal excretion and liver accumulation of polychlorinated dibenzo-p-dioxin in C57BL/6N mice administered dioxin was examined. Mice were administered 2.2 microg of 1,2,3,4,7,8-hexachlorodibenzo-p-dioxin (H6CDD) dissolved in corn oil once after a period of acclimatization, after which they were fed either a basal diet, a 10% C. pyrenoidosa diet, or a 10% Spinach diet, for five weeks. Among mice fed the 10% C. pyrenoidosa diet, cumulative fecal excretion of H6CDD over the first week following administration was significantly greater (9.2-fold) than that observed among mice fed the basal diet. Moreover, excretion during the fifth week following administration of H6CDD was still significantly greater (3.1-fold) among mice fed the 10% C. pyrenoidosa diet than among mice fed the basal diet. Five weeks after administration of H6CDD, liver accumulation of H6CDD in mice fed the 10% C. pyrenoidosa diet was significantly less than that observed among mice fed either the basal diet and the Spinach diet (by 27.9% and 34.8%, respectively). These findings suggest that C. pyrenoidosa may be useful in inhibiting the absorption of dioxins via food and the reabsorption of dioxins stored already in the body in the intestinal tract, thus preventing accumulation of dioxins within the body.

Abstract
A Chlorella powder was screened using 52 in vitro assay systems for enzyme activity, receptor binding, cellular cytokine release, and B and T cell proliferation. The screening revealed a very potent inhibition of human protein tyrosine phosphatase (PTP) activity of CD45 and PTP1C with 50% inhibitory concentration (IC(50)) values of 0.678 and 1.56 microg/mL, respectively. It also showed a moderate inhibition of other PTPs, including PTP1B (IC(50) = 65.3 microg/mL) and T-cell-PTP (114 microg/mL). Other inhibitory activities and their IC(50) values included inhibition of the human matrix metalloproteinases (MMPs) MMP-1 (127 microg/mL), MMP-3 (185 microg/mL), MMP-7 (18.1 microg/mL), and MMP-9 (237 microg/mL) and the human peptidase caspases caspase 1 (300 microg/mL), caspase 3 (203 microg/mL), caspase 6 (301 microg/mL), caspase 7 (291 microg/mL), and caspase 8 (261 microg/mL), as well as release of the cytokines interleukin (IL)-1 (44.9 microg/mL), IL-2 (14.8 microg/mL), IL-4 (49.2 microg/mL), IL-6 (34.7 microg/mL), interferon-gamma (31.6 microg/mL), and tumor necrosis factor-alpha (11 microg/mL) from human peripheral blood mononuclear cells. Chlorella also inhibited B cell proliferation (16.6 microg/mL) in mouse splenocytes and T cell proliferation (54.2 microg/mL) in mouse thymocytes. The binding of a phorbol ester, phorbol 12,13-dibutyrate, to its receptors was also inhibited by Chlorella with an IC(50) of 152 microg/mL. These results reveal potential pharmacological activities that, if confirmed by in vivo studies, might be exploited for the prevention or treatment of several serious pathologies, including inflammatory disease and cancer.

Abstract
Intraperitoneal and pleural immunotherapy has been used as an effective therapy for malignancy. Recently we treated two patients with peritonitis and pleuritis due to cancer by intraperitoneal and pleural administration of IFN-gamma, OK-432 and antitumor agents. One patient with gastric cancer (stage IIIb) was treated with intraperitoneal administration of IFN-gamma and OK-432 in combination with intraarterial infusion of MMC, ADM, 5-FU and CDDP. Two months later, ascites and pleural fluid diminished. Another patient with ovarian carcinoma (stage IV), was administered IFN-gamma, OK-432 and CDDP into ascites with general medication of CDDP and Epi-ADM. Two months later, her ascites and tumor size decreased. This patient was treated with palaplatin every two months for the ten months and hysterosalpingecctomy and tumorectomy of Douglas pouch were performed at the sixteenth month. The histopathological examination of resection from this patient showed complete necrotic tissue of tumor. Endogenous cytokine therapy with intraperitoneal and pleural administration of IFN-gamma for priming and OK-432 for eliciting in combination with antitumor agents may be effective treatment for malignant peritonitis and pleuritis.

Abstract
To increase antitumor effects of transcatheter arterial embolization therapy (TAE) for hepatocellular carcinoma (HCC), immunochemo-embolization therapy via hepatic artery was performed with a mixture of doxorubicin and iodized oil (LPD) following a mixture of gamma-IFN, OK-432 and gelatin sponge, and then a mixture of actinomycin D and gelatin sponge. Three patients with HCC were treated by this procedure. One patient had tumor thrombus in inferior vena cava (IVC). The serum alpha fetoprotein (AFP) levels before this procedure ranged from 66 ng/ml to 8,360 ng/ml. Following this procedure, the serum AFP levels began to decrease for 1-3 months, then increased for 3-6 months, and again suddenly decreased under 10 ng/ml in two cases after initial procedure. The serum AFP levels of two cases revealed under 10 ng/ml for 9-18 months. CT after 2 weeks to 3 months of this procedure showed a low-density area around LPD-uptaking tumor and after 1-8 months decreased tumor in size with diminishing of the low-density area. Therapy for the main tumor of one case with tumor thrombus of IVC proved to be effective, but it was not effective for tumor thrombus of IVC. The reasons that the serum AFP level increased after decreasing for 1-3 months and then fell below 10 ng/ml following this procedure, may be some kinds of immunological antitumor effects produced by endogenous cytokines.

Abstract
To elucidate the relationship between physical activity and the progress of diabetic nephropathy, patients were divided into two groups with physical activity maintained (G) or restricted (R). The period between the onset of 1+ and 3+ proteinuria was 56 +/- 25 months in G and 68 +/- 25 months in R. But the period between 3+ proteinuria and the serum creatinine exceeding 2.0 mg/dl was 29 +/- 19 and 23 +/- 22 months, respectively. Duration of the nephrotic stage before the entry to dialysis was about 27 months in each group. After initiation of hemodialysis or continuous ambulatory peritoneal dialysis (CAPD), postural hypotension tended to be less in G and Karnofsky score for fitness in daily physical activity was significantly better in G. Even after macroalbuminuria emerged, it was concluded that a strict restriction of exercise is of little benefit.

Abstract
Antitumor effect of TNF has been demonstrated to be increased with some kinds of anticancer agents. We reported antitumor effect of hepatic endogenous TNF induced with gamma-IFN and OK-432 for hepatocellular carcinoma (HCC). To increase antitumor effect of transcatheter arterial embolization (TAE), hepatic arterial chemoembolization was performed with a mixture of gamma-IFN, OK-432 and gelatin sponge following a mixture of Doxorubicin and iodized oil (LPO) on the first time. Serum alpha-fetoprotein decreased from 18,903 ng/ml to 470 ng/ml but elevated three months after these procedures. Following the above procedure, hepatic arterial embolization with a mixture of gelatin sponge and Actinomycin D as an inhibitor of RNA was given the second time. Serum alpha-fetoprotein decreased under 5 ng/ml and computed tomography revealed decreased tumor size and low density area following this second procedure. Hepatic arterial chemoembolization with a mixture of hepatic induction of endogenous TNF and anticancer agents may well be beneficial for survival of patient with HCC.

Abstract
Antitumor effect and reduction of tumor size by some cytokines as Biological Response Modifier have been demonstrated by various studies. Endogenous tumor necrosis factor is produced from macrophage. To increase the antitumor effect of transcatheter arterial embolization (TAE) in hepatocellular carcinoma (HCC), we treated 7 HCC patients with endogenous tumor necrosis factor (ETNF) which was induced by hepatic arterial injection of gamma-IFN (1.0-3.0 X 10(6) IU) as priming agent and OK-432 (2-5 KE) as triggering agent. TAE was performed with Lipiodol, ADM and gelatin sponge on 3-10 days after the induction of ETNF. TNF activity was detected in 2 cases and suspected to depend on the dose of gamma-IFN and OK-432. Serum alpha-Fetoprotein levels after the injection of ETNF began to decrease from 3-30 days in 5 patients and remained unchanged in 2 cases. Serum alpha-Fetoprotein levels after TAE with the induction of ETNF were decreased 1-5 months in 5 cases. Reduced size and low-density area on CT scan in 3 advanced cases after these procedures were no different from those of HCC patients treated with TAE alone. In one of two inoperable cases with a single mass lesion in the liver, CT scan after one more added TAE following these procedures showed a low-density area around the Lipiodol uptaking tumor, indicating obstruction of the peripheral portal vein. CT scan of another case revealed low density around Lipiodol in the tumor, which showed complete necrotic change. In all cases, middle-grade fever and hypotension were seen transiently, but these subsided by symptomatic treatment. The antitumor effect of TAE in HCC might be enhanced with ETNF induced by hepatic arterial injection of a low dose of gamma-INF and OK-432.

Abstract
The dose-response relationship and distribution of chromosome aberrations between cells was studied in G0 human peripheral blood lymphocytes following in vitro exposure to 4.9 MeV protons. The dose-response relationship of dicentric yield showed a significant dose-quadratic component and was best expressed by 2.76 X 10(-1) D + 1.36 X 10(-1) D2 (D in Gy). The distribution of dicentrics between cells was over-dispersed compared with a Poisson distribution. Analysis of the data indicated that the over-dispersion was caused by a spatial limitation in the interaction between tracks. The interaction distance was estimated to be around 0.2 microns.

Abstract
In recent years, both a numerical and relative increase in the morbidity of cardiovascular and cerebral vascular diseases has been noted in Japanese diabetics. The trend of macroangiopathy in the period between 1953 and 1980 was studied in 210 autopsy cases (Group A: 1953-62, 27 cases, Group B: 1963-72, 43 cases and Group C: 1973-80, 140 cases). The incidence of myocardial infarction and cerebral infarction as a primary cause of death was 25. 9% in Group A, 23.3% in Group B and 37.9% in Group C. From the autopsy findings, the morbidity of cardiovascular disease was 14.8%, 30.2% and 34.3% respectively. In order to elucidate the clinical risk factors, the age at death, duration of diabetes at the time of death, and incidence of hypertension and serum cholesterol in the past history were studied. The percentages of those aged over 70 at death was 18.5%, 23.3% and 42.8% respectively, and those of the cases with durations of more than 10 years was 25.9%, 40.5% and 51.8% respectively. The prevalence of hypertension and hypercholesterolemia was almost identical in each group. From the above, the previous increase in the death-rate due to coronary heart disease and cerebrovascular disease in Japanese diabetics is thought to be attributable to the increasing number of elderly diabetics of long duration.
