From April 1983 through March 1993, 10, 767 women underwent health examinations at the Health Care Center in Obihiro Kosei Hospital. Cervical smears were taken from theuterine cervix for cervical cancer screening. One hundred and six women had abnormal results, greater than class III. Those patients who were diagnosed as having carcinoma numbered 10 (0.09%). Of the cervical carcinomas found, 1 was frankly invasive (adenocarcinoma Ib); 3, microinvasive (2; squamous cell carcinoma and 1; co-existence of adenocarcinoma and squamous cell carcinoma); and 6, carcinomas in situ (squamous cell carcinoma).

From January 1981 through December 1986, 27, 513 individuals consisting of 17, 918 males and 9, 595 females underwent health examinations at Health Care Center in Obihiro Kosei Hospital. 14.2% of healthy and asymptomatic men and 29.1% of healthy and asymptomatic women had microscopic hematuria (one or more RBCs per HPF).
To evaluate the clinical significance of microhematuria, about one third of patients with asymptomatic microhematuria who had undergone complete urological examination were reviewed.
Genitourinary neoplasms were found in 0.21%(8 bladder cancers, 2 prostatic cancers and 1 renal cell cancer). The incidence of cancers increases proportionate to increase in age, furthermore, lesions were found more commonly in men than in women. We could find no relationship between the degree of hematuria and the cause. The results suggest that patients with asymptomatic microhematuria should undergo urological examinations.

This study aimed to clarify the effects of watching forest videos on prefrontal cortex activity. We examined oxy-hemoglobin (oxy-Hb) levels in the prefrontal cortex using near infrared spectroscopy (NIRS) and measured the changes in relaxation level using the rating scale of emotion as defined in terms of relaxation (RE scale), and the free description data after watching the videos. We recruited 21 healthy female university students for this study. All subjects watched a forest video and an urban video in a random order; no significant differences were found in comparisons between the two conditions during and after watching the videos. Comparisons of oxy-Hb levels in the prefrontal cortex during and after watching the two videos showed a significant increase after watching the forest video. Significantly decreased scores of three RE scale items, i.e., “anxiety-relief,” “restrictive-free,” and “discomfort-comfort,” were observed with the urban video. The forest video significantly improved scores of the following items: “feeling high-stable,” “tense-relaxing,” “anxiety-relief,” “restrictive-free,” and “discomfort-comfort.” These results suggest that the forest video activates the left prefrontal cortex and subjectively enhances a relaxed feeling, after watching.
