The site of bleeding was not detected with either gastroduodenal endoscopy or upper abdominal computed tomography,the latter of which did not include the iliopsoas muscle.He died on the 10th day of admission and bilateral iliopsoas hematomas were found on autopsy.An iron stain was positive in the iliopsoas muscle.Eight cases of muscle hematoma associated with cirrhosis,including the present case, were found in a review of the literature.Four of these cases involved the rectus abdominis muscle,3 involved the iliopsoas muscle and 1 involved combined muscles.Alcoholic cirrhosis accounted for 75%of the cases.One case(12.5%)was associated with virus- related cirrhosis,and another with combined virus- and alcohol-related cirrhosis.The mortality rate was 75%despite early diagnosis and low risk scores for cirrhosis.Muscle hematoma in patients with cirrhosis isclosely related to alcoholism,and the mortality rate of the condition is extremely high.In conclusion,muscle hematoma should be recognized as an important complication of cirrhosis.展开更多

The serum testosteron e concentrations of 28 volunteers were investigated daily during abstinence peri ods after ejaculation for two phases. The authors found that the fluctuations o f testosterone levels from the 2nd to 5th day of abstinence were minimal. On the 7th day of abstinence, however, a clear peak of serum testosterone appeared, re aching 145.7% of the baseline (P<0.01). No regular fluctuation was observed foll owing continuous abstinence after the peak. Ejaculation is the precondition and beginning of the special periodic serum testosterone level variations, which wou ld not occur without ejaculation. The results showed that ejaculation-caused va r iations were characterized by a peak on the 7th day of abstinence; and that the effective time of an ejaculation is 7 days minimum. These data are the first to document the phenomenon of the periodic change in serum testosterone level; the correlation between ejaculation and periodic change in the serum testosterone le vel, and the pattern and characteristics of the periodic change.展开更多

In this experiment twenty healthy male subjects were required to perform a driving simulator task for 3-hours. The physiological variables for evaluating driver mental fatigue were spectral values of blood pressure variability (BPV)including very low frequency (VLF), low frequency (LF),high frequency (HF). As a result, LF, HF and LF/HF showed high correlations with driver mental fatigue but not found in VLF. The findings represent a possible utility of BPV spectral analysis in quantitatively evaluating driver mental fatigue.展开更多
