Background：Although octreotide is effective in the relief of symptoms of gastrointestinal obstruction, it is also effective for gastrointestinal bleeding. It has been reported that octreotide reduced the splanchnic blood flow, and reduced the bleeding from esophageal varices, peptic ulcer and the tumor of gastrointestinal tract. We experienced four cases of end―stage cancer patients admitted to a palliative care unit whose symptoms of gastrointestinal bleeding were alleviated by octreotide（300μg／day）. Case：Case 1；A 75―year―old woman with gastric cancer developed melena and received octreotide. After octreotide was discontinued, melena and hematemesis recurred. Octreotide was restarted subsequently, and hematemesis resolved. Case 2；An 87―year―old woman with gastric cancer received octreotide for increase of bloody drainage from a stomach tube. She had epigastric pain and emotional distress from the blood. These symptoms were alleviated following the administration of octreotide. Cases 3 and 4；A 76―year―old man with gastric cancer and a 62―year―old man with bile duct cancer received octreotide for massive vomiting of blood. After the administration of octreotide, there was no reoccurrence of hematemesis in both patients. Conclusion：Octreotide may alleviate symptoms of gastrointestinal bleeding in end―stage cancer patients.

Ginseng powder was dissolved in the warm water to develop bath salt that contained Ginseng powder (250mg: 1% Ginseng powder, 500mg: 2% Ginseng powder) and it made comparative study of the effects with the tap warm water for seven healthy adults (male 3, female 4, 20.7±0.8 years old). The Ginseng powder of 250mg and 500mg was made so that the bath salt of 25g may become 1% and 2%. The whole body immersion of 15 minutes was done to all subjects under the condition that 1% or 2% cannot be distinguished without tap water bathing.
As a result, the warm water with Ginseng powder increased in the changes of the deep thermometer in front of chest between immersion and after bathing, compared with the tap warm water. But there were not significant change of the surface skin temperature on the arm and the tissue blood flow on thigh skin.
Therefore, the warm water with Ginseng powder was suspected that the thermo effects and the retaining warmth were good compared with the tap warm water.
It seemed that it was possible to use it safely as bath salt for it did not change of the blood pressure, the heart rate, and abnormality of the skin without the case to whom the skin had temporarily flushed, was not additionally recognized.

Purpose: With a decreasing degree of independence in excretion movement, terminally-ill cancer patients experience an emotional distress and a lower sense of self-esteem. We herein report a case in which a patient received an effective excretion care by a palliative care team. Case: A female patient in her 60s was diagnosed with lung cancer and multiple bone metastases. On admission, she maintained her basic ADL (Activities of Daily Living) and walked independently; following a fall in the bathroom, however, she sustained a pathological fracture in the left humerus that was treated conservatively from a prognostic point of view. Despite concerns about pain and fracture risks during her trips to and from the bathroom, she wanted to excrete “on the toilet.” Out of respect for her wish and sense of pride, we gave her movement, lifting, and undergarment operation trainings in addition to adequate pain control. We also adjusted the equipment and increased the carers for her. With a gradual worsening of pain and a decline in ADL, she nevertheless had been able to perform excretion movement until the last moment when she was placed under sedation. Conclusion: This case suggests that an effective excretion care is possible by team approach respecting patients’ QOL and sense of dignity.

An unsigned questionnaire survey of smoking was taken on all 101 students of JA Gifu Kouseiren Nurses' School. The smoking rate of the students as of July 2001 worked out at 17.8%(18 in 101 students). Most student smokers said they smoke less than 15 cigarettes a day, each containing less than 0.9mg of nicotine, and their Fagerstrom Tolerance Questionnaire (FTQ) index came to 1.94±1.51, suggesting their nicotine dependence is not so much as we thought. Almost 80% of the students who habitually smoke said they wish to quit smoking. Almost 80% of the students who do not smoke said they feel unpleasant to other person's smoking, and in contrast the remaining 20% of them said they feel like start smoking. These results suggest that there is a pressing need for advising the nurse students not to form the smoking habit and bringing the harm of smoking home to them in class.

This review is partly composed of the presentation "Cytokine alteration and speculated immunological pathophysiology in silicosis and asbestos-related diseases" delivered during the symposium "Biological effects of fibrous and particulate substances and related areas" organized by the Study Group of Fibrous and Particulate Studies of the Japanese Society of Hygiene and held at the 78th Annual Meeting in Kumamoto, Japan. In this review, we briefly introduce the results of recent immunological analysis using the plasma of silica and asbestos-exposed patients diagnosed with silicosis, pleural plaque, or malignant mesothelioma. Thereafter, experimental background and speculation concerning the immunological pathophysiology of silica and asbestos-exposed patients are discussed.

Asbestos exposure is known to cause malignant mesothelioma, which is associated with poor prognosis. We focused on and examined the effect of asbestos exposure on the differentiation and function of cytotoxic T lymphocytes (CTLs). CTLs have the ability to specifically attack tumor cells after being differentiated from naïve CD8 T cells following antigen stimulation. Exposure to chrysotile B asbestos suppressed the differentiation of CTLs during the mixed lymphocyte reaction (MLR) and was associated with a decrease in proliferation of CD8 T cells. Additionally, in an effort to investigate the mechanism associated with suppressed CTL differentiation upon exposure to asbestos, we focused on IL-2, a cytokine involved in T cell proliferation. Our findings indicated that insufficient levels of IL-2 are not the main cause for the suppressed induction of CTLs by asbestos exposure, although they suggest potential improvement in the suppressed CTL function. Furthermore, the functional properties of peripheral blood CD8 lymphocytes from asbestos-exposed individuals with pleural plaque (PP) and patients with malignant mesothelioma (MM) were examined. MM patients showed lower perforin levels in CD8 lymphocytes following stimulation compared with PP-positive individuals. The production capacity of IFN-γ in the MM group tended to be lower compared with healthy volunteers or PP-positive individuals. In an effort to determine whether chronic and direct asbestos exposure affected the function of CD8 T cells, cultured human CD8 T cells were employed as an in vitro model and subjected to long-term exposure to chrysotile (CH) asbestos. This resulted in decreased levels of intracellular perforin and secreted IFN-γ. Those findings underlie the possibility that impaired CD8 lymphocyte function is caused by asbestos exposure, which fail to suppress the development of MM. Our studies therefore reveal novel effects of asbestos exposure on CTLs, which might contribute towards the development and implementation of an effective strategy for the prevention and cure of malignant mesothelioma.
