A 59-year-old woman was referred to our hospital with a complaint of a pulsatile mass in the right inguinal region four months after total hip replacement. Right femoral arterial injury owing to continuous contact with a fold of excess cement used in the fixation of the hip prosthesis was suspected to be the cause of the false aneurysm. Moreover, two months after the total hip replacement, the right lower leg was amputated at the below-knee level for acute ischemia due to arterial thromboembolism probably originating from the false aneurysm. False aneurysm due to direct vascular injury deserves consideration as a possible complication of total hip replacement.

Effects of 5 km running upon taking a low-carbohydrate, high-fat and protein diet on the body, in fourteen healthy young males and three healthy young females, all being affected by taurine inducement, were investigated by double blind test method. The results obtained were as follows ;
1) As to the degree of in heart rate upon 5 km running, in males, there were no differences between taurine administration group (M-group) and placebo administration group (P-group) . But in females, recordings in P-group were much larger than those of M-group.
2) As to the degree of increase in systolic blood pressure upon 5 km running, in males, no differences between both groups were observed, but in females, recordings in P-group were larger than those of M-group.
3) Both serum creatine kinase (CK) and creatine kinase isoenzyme (CK-MB) activities did not recover to pre-exercise levels during 3 days after 5 km running in both groups of both sexes.
4) In the rate of CK-MB against CK, not only P-group of females had extraordinary high levels immediately after 5 km running, but also P-group of both sexes had higher levels on 3rd and 5th day after 5 km runnning than M-group.
5) In both sexes P-group was larger than M-group in the degree of increase in blood lactate and serum triglyceride levels.
6) As to the changes in serum total protein levels, in males, no differences between both groups were observed, but in females, P-group had extraordinary low levels on 1st day after 5 km running and maintained low levels during 5 days recovery.
7) As to the changes in both serum total fatty acids levels and the rate of unsaturated fatty acids against total fatty acids, no differences were observed between both groups of both sexes.
8) As to the degree of increase in plasma noradrenalin and adrenalin levels, in males, no differences between both groups were observed, but in females, recordings in M-group were larger than those of P-group.

Effects of taurine on the functions of the body and metabolism with 3km running upon taking a diet, which is constituted of lowest possible amount of carbohydrate and highest possible amount of fat and protein, were investigated in 25 male and female subjects of age thirties by double blind test method. The results were as follows
1) Taurine administration (T. A.) proved to inhibit the degree of increase in heart rate and increase the maximal degree of pulse pressure in response to 3 km running.
2) T. A. proved to inhibit the degree of increase in serum creatine kinase isozyme MB (CK-MB) activities and CK-MB/CK ratio.
3) T. A. proved to inhibit the decrease of serum total protein values immediately before running and in the following morning. Similar trends in terms of the particuler times were observed, too, in the case of the degree of decrease of serum triglycerides values.
4) T. A. seemed to accelerate the utilization of saturated fatty acids especially.
5) Three kilometer running seemed to increase in serum taurine concentrations from several hours after running to the morning immediately after running.

The present study was performed to investigate the effects of 120 km walking, 40 km a day for 3 successive days on the condition that taking rest and foods freely, upon physical functions for healthy male and female subjects. All measurements were enforced at postabsorptive state early in the morning for the 10 successive days including the days of walking. Blood pressure, heart rate, and body weight were measured every morning. Blood samplings enforced, too. Urine collections were enforced from first day to 7 th day. The results obtained were as follows;
1) There were no changes in heart rate, blood pressure, and body weight, which were measured early in the morning, before and after 120 km walking.
2) Serum GOT and GPT activities had little changes, while serum LDH, α-HBDH, and CK activities increased gradually after walking.
3) Serum CK-MB activities, which indicate myocardial injury, increased after walking, on the contrary CK-MB/CK ratio decreased. It was suggested that effects of 120km walking to myocardium were rather than slight ones.
4) In spite of the same sorce in which serum CK-MB and LDH-1 were resulted, both did'nt exhibit same patterns in serum.
5) Serum lipids decreased gradually after walking.
6) Urinary excretion of creatinine and uric acid increased after 120km walking especially.
7) If it is allowed to take sufficient foods and rest, 120km walking, 40km a day for 3 successive days, would not result in such a physical stress over the following days.
