A study was conducted to investigate the mechanism of bone atrophy in various strains of inbred mice under the influence of tail-up suspension. Nine inbred strains of mice (NZB/N, NZW/N, AKR/N, Balb/C, C 57 BL, C 3 H/He, A/J, DBA, CBA/N) aged six weeks were used. Each strain was divided randomly into two groups, a suspension group (SG; n=5) and a control group (CG; n=5) . The suspension group were etherized and suspended with an elastic bandage. After one week, the tibiae were removed and their bone weights were measured using an electric balance (Metler; AE 240) . Their length was also measured with a vernier caliper. In all strains, body weight in the SG was significantly lower than that in the CG. From the bone weight and length in the CG, bone growth in the NZB/N, AKR/N, NZW/N and C3H/He strains was considered to be higher than in the other strains. On the other hand bone growth in the DBA, A/J, Balb/C, and CBA/N strains were lower than in the others. The absolute value of bone weight in the SG was significantly smaller than that in the CG in six strains (NZB/N, C 57 BL, A/J, NZW/N, C 3 H/He, Balb/C) . However in the DBA strain, the absolute value of bone weight in the SG was significantly higher than that in the CG.
From the results of this investigation we suggest that the mechanism of normal bone growth is not the same as the mechanism of bone atrophy induced by tail-up suspension.

Direct observation of the intravascular atherosclerotic change provides many diagnostic information and supports successful vascular surgery. Angioscopic inspections were performed in the 23 patients who underwent laser angioplasty for the peripheral arteries and 7 patients with aorto-coronary bypass surgery in this study. Useful images could be obtained in 19 (83%) of 23 observations in the peripheral arteries, and the successful rates of angioscopic observation were influenced by the diameter and the degree of kinking of each vessel. On the other hand, intraoperative observation of coronary artery with angioscope could be performed easily in all cases. From these findings, intraoperative application of angioscopy was considered to be useful procedure for the cardiovascular surgery.

A digital teaching material on the cardiac cycle, which discretely illustrates only the left heart system, not the right, and shows the pressure of each section clearly with an illustration of a water pipe pressure gauge, as proposed by G. Doman et al., was presented to medical students, who had not previously learned circulatory physiology. Many formative questions were also provided to promote active learning. After learning the material, the students were given an anonymous questionnaire comparing the present material with a standard textbook of physiology as the control. When asked the overall impression, 86% of the students supported the present material.

Purpose：We evaluated that the current state from which a palliative care unit receives emergency admission of cancer patients at home. Methods：We retrospectively investigated the medical records of 393 cancer patients who hospitalized in our unit between January 2013 and December 2014. The patients were shared with a group of two, schedule admission (schedule group) and emergency admission (emergency group), and it was compared with a result on discharge and with a hospitalization period. We investigated admission process, the date and time of admission, and reason for admission in emergency group. Results：The number of patients was 224 of schedule group and 169 of emergency group. The mortality rates were 81% in schedule group and 78% in emergency group (not significant). An emergency group for an average of 24.3 days was shorter for 9 days than schedule groups in a hospitalization period of dead leaving patients (p<0.05). In emergency group, admission process included 128 completed-interviews with the hospitalization, 11 incompleted-interviews before admission and 30 first visits, and 129 patients (76％) admitted within the weekday daytime. Many patients had a complaint of severe pain, appetite loss and oral absorption difficulty, and so much. Conclusions：An emergency group admitted the various processes and the much symptom. There were a lot of cases of early hospital death, but also admitted return at home, and our unit played the role of emergency admission.
