We successfully performed one-stage definitive repair for 3 infants weighing 4.2, 6.1 and 5.2kg with complex coarctation without homologous blood transfusion. The priming volume of the bypass circuits was 195ml, and their lower hematocrit values during cardiopulmonary bypass were 15, 16 and 13%, respectively. In order to diminish the aortic cross clamp time, the aortic arch was repaired with the heart beating, using isolated cerebral and myocardial perfusion methods. The base excess in each patient decreased to -9.4, -8.0 and -4.9mEq/l during the rewarming phase, however, their postoperative hemodynamic and respiratory conditions were satisfactory. They have grown without any sequelae for at least 2 months.

60 cancer patients between the ages of 20 and 80 who had completed a main treatment were randomly administered Tabebuia Avellanedae (Taheebo) extract 2.0 g/day (usual dosage), 4.0 g/day (2 times dosage), or 6.0 g/day (3 times dosage) for 6 months. A blood biochemical exam, urinalysis, adverse effects, several immunological parameters, urine 8-OHdG and QOLsurvey were evaluated. Five patients dropped out, but there was no direct cause and effect between the extract and dropout. Although several items of the blood biochemical exam revealed slight variation within the normal limits, distinct abnormities were not detected. Furthermore, side effects like allergic symptoms were not found. Immune parameters and urine 8-OHdG did not change significantly. CRP, which is a sensitive marker of inflammation, was significantly improved, and this may suggest the possibility of this extract helping to prevent hardening of blood vessels due to arteriosclerosis. In Japan, long-term food safety tests have rarely been done, therefore we recommend that more of these exams be carried out.

We evaluated the safety of fucoidan from Gagome Kombu (GKF) in genotoxicity tests. In bacterial reverse mutation test, GKF had no reverse mutation inducing activity on five bacterial strains with or without S9 metabolic activation. In chromosome aberration test, GKF had neither structural nor numerical chromosome aberration inducibility with or without S9 metabolic activation. In micronucleus test, neither formation of micronuclei nor decrease of mironucleated reticulocytes was observed in the bone marrow of the mice treated by GKF. These results indicate that GKF has no genotoxic activities under the condition of this study.

Object: Gagome kombu (Kjellmaniella cracciforia) is the edible brown seaweed and contains fucoidan, a sulfated polysaccharide, abundantly. Bunashimeji (Hypsizigus marmoreus) is the popular Japanese mushrooms and contains polyterpenes as the bitter substance. Previously, we investigated the bioactive functions (e.g. anti-tumor action) and the safety of fucoidan from Gagome kombu (GKF) and the extract from Bunashimeji (KTE: Kinoko terpene extract). In this study, we evaluate the influence of GKF and KTE on hepatic cytochrome P450 (CYP).
Methods: Male SD rats were divided into three groups (n = 5). 2,000 mg/kg of GKF and KTE were given orally once daily for 4 days.
Result: There were no difference in activities and mRNA expressions of hepatic CYPs (CYP2C11, CYP2D, CYP2E1 and CYP3A1) among all groups.
Conclusion: These results indicated GKF and KTE did not influence the rat hepatic CYPs.

Objective: Gagome kombu (Kjellmaniella crassifolia), an edible brown seaweed grown around the southern area of Hokkaido, is known to abundantly contain fucoidan. Previous studies show that on animals, fucoidan from Gagome kombu (GKF) exhibits immune-enhancing, anti-cancer and anti-influenza virus capabilities. In this study, we focused on the elderly and evaluated the safety and immune-efficacy of GKF.
Methods: Eighteen (18) Japanese elderly subjects were chosen to ingest the test samples (3 tablets/day containing 50 mg GKF and lactic acid bacteria) for 8 weeks. Before ingestion and every 4 weeks thereafter (4th and 8th week), blood chemistry analysis, hematological analysis, urinalysis and immune analysis were conducted.
Result: Test results showed no adverse clinical changes in blood and urinary analysis. In addition, no serious symptoms were observed. Moreover, GKF markedly decreased serum IgE levels.
Conclusion: These results indicate that in the case of elderly, GKF is a safe functional food ingredient.

Purpose: In Kasugai City Hospital, we have introduced palliative care clinical pathway with a focus on decision-making support on the intention of recuperation location in addition to symptom relief. In this study, it is intended to explore the factors that make it difficult to home discharge of cancer inpatients with the intention of discharged home on the basis of the information on the clinical pathway. Methods: The subject patients were cancer inpatients who had expressed the intention of the discharge to the home during period from June 2014 to August 2015. We examined the medical records of the target patient retrospectively. Logistic regression analysis was performed in order to clarify the factors that make it difficult to home discharge. Results: Of 43 patients, 25 patients (58.1%) were discharged from the hospital to the home. As a result of logistic regression analysis (multivariate analysis), delirium and living alone have been extracted as the predictive factors that makes it difficult to home discharge. Conclusion: Delirium and living alone have been suggested as the factors that makes it difficult to home discharge of patients who wish to home discharge. Early detection and early treatment of delirium are important, and early collaboration between the hospital discharge support department and palliative care team for the living alone patient is also necessary.

Objective: Fucoidan, a sulfated polysaccharide in Gagome kombu (GKF) is known to exhibit immune-enhancing and anti-cancer activities. Recently, cancer patients use various dietary supplements containing fucoidan and mushroom extracts. However, there have been few reports on the safety and efficacy of fucoidan-containing supplements. In this study, we examined the safety of long-term ingestion of GKF in cancer patients.
Methods: Twenty six (26) Japanese cancer patients—16 of whom (male 6, female 10, age 62.8 ± 10.7) have completed cancer treatment and 10 (male 4, female 6, 67.0 ± 10.6) still under treatment and regularly taking anti-cancer drugs and hormone pills—were chosen to ingest GKF-containing supplements (200–300 mg/day) for 8 weeks. Before ingestion and every 4 weeks thereafter (4th and 8th week), blood chemistry analysis, hematological analysis, urinalysis and immune analysis were conducted.
Result: There were no adverse clinical changes in blood and urinary analysis. In addition, no serious adverse effects were observed.
Conclusion: These results indicate long-term ingestion of GKF is indeed, safe for cancer patients.

In order to find an effective way to detect bacteria responsible for respiratory tract infections in children, we first examined as pharyngeal swabs, epi-pharyngeal swabs and nasal aspirates obtained from children hospitalized at our pediatric service during these five months from December 1997 to April 1998. In the rate of bacterial infection, it was found that nasal aspirates came out on top with 92.6%(25/27), followed by epipharyngeal swabs with 71.6%(53/74) and pharyngeal swabs with 26.2%(38/145). Single-species bacteria were found in 78.9%(30/38) of pharyngeal swabs, where as 45.3% of epi-pharyngeal swabs (24/53) and 52.0% of nasal aspirates (13/25) proved mixed infections with two-or three-defferent species. Thus it was suggested that nasal aspirates and epi-pharyngeal swabs would be far more adequate than pharyngeal swabs to detect bacteria with accuracy.
Next, based on the efficiency of bacterial detection, we compared culture media for the specimen obtained from in-patients and out-patients at our pediatric service. The rate of isolation of gram-negative rods was as low as 0.3%(1 of 314 strains) even when BTB agar plate, a selective medium for these bacteria, was employed. The sensitivety was not much different from those observed with nonselective blood agar plate. These results suggest that the conventional blood agar media can substitute for the more expensive type of BTB agar medium for the diagnosis of infections diseases of the airwaysin children.
