    Notes: Summary Chemoembolization therapy, using the arterial injection of mixtures of various anticancer agents and lipiodol along with gelfoam particles, was carried out on 77 cases of hepatocellular carcinoma between January 1985 and March 1987, and an assessment was made on the anticancer effects of this treatment method. For the patients receiving lipiodol, the value of the longitudinal dimension multiplied by the vertical length of the tumor was calculated using a computerized tomograph before and after chemoembolization to determine the rate of tumor regression. (a) Of the 30 patients receiving chemoembolization therapy using a simple mixture of 100 mg cisplatin (CDDP) and lipiodol, the tumor regression rate was 50% or more in 10 cases (31%). (b) Of the 14 patients receiving chemoembolization therapy with a suspension of 100 mg of cisplatin, adriamycin (10–30 mg) and lipiodol, the tumor regression rate was 50% or more in four cases (29%). (c) Of the 31 cases receiving chemoembolization therapy using a suspension of adriamycin (10–40 mg), mitomycin C (10–20 mg) and lipiodol, the tumor regression rate was 50% or more in four cases (13%). (d) From these results, it can be concluded that the antitumor effect of chemoembolization using cisplatin is more significant than with other drugs.

    Notes: Introduction: Previous studies have suggested that paroxysmal atrial fibrillation (PAF) of vagal origin often occurs at night and PAF of sympathetic origin occurs during the daytime; however, autonomic tone after spontaneous termination of PAF has not been determined. The aim of this study was to evaluate by heart rate variability (HRV) analysis the relationship between the time of PAF onset and autonomic tone before and after PAF. Methods and Results: Twenty-three patients ( 65 ± 2 years) who underwent 24-hour ambulatory monitoring, had one or more episodes of PAF (〉30 min), and had maintained normal sinus rhythm for 〉60 min before/after PAF were enrolled in this study. Mean duration of PAF was 6.2 ± 1.2 hours. HRV parameters were analyzed in a 10-minutes section at 60 minutes, 20 minutes, and immediately before the onset of PAF and after its termination. PAF began at night in 14 patients (group N) and during the daytime in 9 patients (group D). In group N, the high-frequency (HF) component and low-frequency (LF) component showed a significant decrease after PAF; PAF was preceded by a gradual increase in HF and LF. Changes in the LF/HF ratio, however, did not occur before or after PAF. Conversely, group D showed a significant increase in the LF/HF ratio before PAF and a decrease in LF and the LF/HF ratio after PAF, but no changes in HF. These changes in HRV parameters were not influenced by the duration or termination time of PAF. Conclusion: This study suggests that the autonomic nervous system plays an important role in both the initiation and termination of PAF. Furthermore, the time of PAF onset influences the autonomic tone at the initiation and termination of PAF. (J Cardiovasc Electrophysiol, Vol. 14, pp. 559-564, June 2003)

    Notes: The purpose of this study was to evaluate heart rate variability (HRV) in patients with familial amyloid polyneuropathy (FAP) using the time- and frequency-domain analysis. The study population consisted of 19 patients with FAP, and 19 age and sex matched normal volunteers. The 24-hour Holter recordings of all subjects in sinus rhythm and off medication were analyzed. Five time-domain indices of HRV were computed. The frequency component of HRV was calculated by fast Fourier transform analysis of the RR intervals. The power spectrum of the low frequency (LF) between 0.04–0.15 Hz and high frequency (HF) between 0.15–0.40 Hz and the LF/HF ratio was calculated. Global measures of HRV including the standard deviation of the mean of RR intervals (SDNN) and the standard deviation of 5-minute mean RR intervals (SDANN) were decreased in patients with FAP. Specific vagal influences on HRV including the proportion of RR intervals more than 50 milliseconds different (pNN50) and the HF power on spectral analysis were less in patients with FAP. LF power and LF/HF ratio were more decreased in patients with FAP at the advanced stage than at the early stage. In conclusion, HRV was significantly decreased in patients with FAP at the early stage, and sympathetic activity was more decreased in patients at the advanced stage. These findings suggest that the decrease of the HRV is an indicator of this disease and the power spectral analysis of the HRV is beneficial in assessing the severity of the autonomic dysfunction.
