The purpose of this study was to examine the effectiveness of the cultured Cordyceps sinensis (Cs, supplement) powder during exhaustive running of human comparing with the placebo (control). These supplements were given to 36 male sedentary subjects over period of 2 weeks. During the exercise, following bio-signals were measured such as the respiratory variables (VO2, VCO2, VE), the blood pressure (BP), the heart rate (HR), and the lactic acid (LA). In addition, their storing urine for one night was inspected about the catecholamine (CA, Adr, NorA, Dop) and the cortisol hormone (17-KA-S and 17-OHCS) at the pre-and the post-ingesting with those supplements. The changing ratio calculating between the pre- and the post-variables of VO2/kg (5.2±0.1 & 4.8±0.1 ml), VE (12.0±0.2 & 11.0±0.2 L), and LA (6.1±2.1 & 5.2±2.6 mmol/dl) had decreased to lower percentages at the recovery period from the exercise test than those of CON, significantly (p<0.01). Futhermore, concentration of the total CA (1.19±0.51 & 1.29±0.49 mg/L), Adr (13.5±1.2 & 17.7±1.9μg/L), NorA (127.4±8.1 & 130.0±8.5μg/L), Dop (1.06±0.1 & 1.14±0.4mg/L), 17-OHCS/creatinine (4.42±0.30 & 4.2±0.31), and 17-KS-G/creatinine (3.18±0.09 & 3.06±0.07) showed changes of significant difference related to the placebo (p<0.05). There have been appeared an augmentation of the energy generation and the anti-fatigue ability intaking with this supplement during the exercise test. During this prolonged exercise, ingesting with this Cs might elicit the superior efficiency and the economical function on the energy metabolism.

Object : The purpose of this study was to test the response of the decline in heart rate (HR) induced by compression on the eyeball (eyeball pressure : EP) and voluntary non breath (VNB) after pedaling exercise. Methods : EP ; Nine male subjects performed exercise for 3 min in a supine position using a bicycle ergometer. Immediately after the exercise all subjects received EP for 10 seconds. After that, subjects undertook the same protocol without EP (CON-E). VNB ; Four male and two female subjects performed exercise for 5 minutes using a bicycle ergometer. Immediately after the exercise subjects received VNB for 7 seconds. After that subjects undertook the same protocol without VNB (CON-V). Results : The slope of the decline in HR recovery (HRDS) after exercise in EP increased significantly more than that in CON-E (p<0.05). However, time constant (HRTC) in CON-E declined faster than that in EP. Thereby, the relationship between HRDS in EP and HRTC in CON-E correlated (r=-0.562). The HRDS of VNB was greater than that of EP and CON-V. However the relationship between HRDS in VNB and HRTC in CON-V did not correlate. Conclusion : We suggest that EP affects vagal nervous activity and VNB affects strength of baroreflex sensitivity. Therefore HRDS of EP might evaluate vagal nervous activity.

A survey has been under way on the incidence of cerebral apoplexy among the inhabitants (pop. 105, 185, National Census, 1970) of the Saku district of Nagano Prefecture since April 1972.
This survey, which constitutes a WHO cooperative study, has been under way with cooperation rendered by the local Medical Association, Association of Public Health Nurses in Saku District and Saku Public Health Center with the Saku Central Hospital acting as the survey center.
In the period of two years till March 1974, 585 persons were registered as having been seized with cerebral apoplexy. The annual incidence rate stood at 265 per 100, 000 population. Classified by types of cerebral apoplexy, cerebral hemorrhage accounted for 26%, cerebral thrombosis for 57%, cerebral embolism for 3%, subarachnoid hemorrhage for 9%, and other types for 5%.
By sexes, the incidence rate among males was 1.3 times higher than among females. By ages, the incidence was highest in the seventies.
When the prognosis of cerebral apoplexy is viewed in terms of deaths in the early period of less than three weeks after the onset, the mortality rate stood at 45%.
The hospitalization rate of patients seized with cerebral apoplexy was 55%. There was a significant difference in the mortality rate between inpatients (with 28%) and outpatients (65%).
The ratio of concurrence of autopsy and clinical diagnosis stood at 83% with Okinaka's criteria and 79% with Ikeda's CVD index.
The incidence of hypertension before the onset of cerebral apoplexy was extremely high among the patients seized with cerebral hemorrhage and cerebral infarction.With respect to the treatment of hypertension, the discontinuance of treatment and the failure to undergo it are high in percentage among the patients seized with cerebral hemorrhage. With reference to cerebral infarction patients of 70 years and older in age, there is little defference between the group who discontinued or failed to undergo treatment and the group who underwent it.
The recurrence of cerebral apoplexy stood at 11% for cerebral hemorrhage, 19% for cerebral infarction, and 11% for subarachnoid hemorrhage.
