In a previous paper, we reported the efficacy of auricular acupuncture in the treatment of hypertension. In the present study, auricular acupuncture was applied to two groups of patients: those taking hypotensive drugs for a long time and those taking no drugs. The difference in the efficacy of the therapy between the two groups was investigated. The fluctuation of blood pressure, the renin activity and catecholamines concentration in the blood during a three-month period were examined.
Patients, who had essential hypertension without any obvious underlying disease, were classified into three groups according to World Health Organization's criteria as follows:
Group I. (Hypertension) exceeding systolic value of 160mmHg, or exceeding diastolic value of 95mmHg. Group II. (Boundary Zone) neither Group I nor II. Group III. (Normal) below systolic value of 140mmHg or diastolic value of 90mmHg.
A subcutaneous needle was inserted horizontally in the anterior direction at the hypotensive point in the fossa triangularis, and then left there. Once a week, the needle was changed, and the blood pressure was measured. The efficacy was evaluated two weeks later as follows: A case which moved from Group I to III was “remarkable”. A case from Group II to III or from Group I to II was “effective”. An unmoved case was “unchanged”. A case from Group II to I was “aggravated”.
Result: No drug group. The efficacy of the auricular acupuncture was noted in 84% (32%: remakable, 52%: effective) of the nineteen Group I, II patients who were taking no hypotensive drugs. Drug group. The efficacy of the auricular acupuncture was noted in 50% (21%: remarkable, 29%: effective) of the twenty-four Group I, II patients who were taking hypotensive drugs. Druing the three-month period, both systolic and diastolic pressure in all the patients in Group I and II showed a significant decrease.
The serum renin activity showed a tendency to decrease but only within the normal range. The concentration of catecholamines changed also within the normal range, though no consistent tendency was seen.

Introduction
Essential hypertension is one of the leading causes of hypertension; responsible for more than 90% of such cases. Diet cure or drug treatment are usually prescribed for this disease. We drew notice to the antihypertensive effects of acupuncture.
Method
Subjects were healthy persons as well as patients complainig of simple essential hypertension. According to the WHO method, they were divided into three groups, e. g. normal, limitaneus, hypertensive. In situ needles were inserted in the antihypertensive points of both auricular sides for one week.
Effect
This treatment gave immediate results in 70% of the limitaneus and hypertensive groups. There was no observable effect for the balance. A number of these subjects were obese; a factor to be considered.
Evaluation
This method is very uncomplex and takes but minimal amount of time to treat patients.

We conducted a large-scale survey of sports injuries in college athletes. This study aimed to investigate trends in sports injuries and disabilities among college athletes by gender, discipline, individual and team competition, contact and noncontact competition, and other competition characteristics. A total of 1,137 college athletes (786 men and 351 women) were surveyed. A questionnaire survey was conducted to determine the club, regularity, and history of sports injuries and disorders (presence/absence, severity, time of injury, site of injury, diagnosis, and recurrence). The prevalence of sports injuries among college athletes was 59.7%. The prevalence was 74.7% in team and contact sports, with ankle and knee ligament injuries accounting for most injuries. The second highest prevalence rate was 66.7% for individual/contact sports, where martial arts-type sports are common. Elbow injuries were common due to the characteristics of martial arts-type sports. Chronic sports injuries of the ankle were common in noncontact/individual sports, and shoulder joint disorders were common in noncontact/team sports. Different trends in sports injuries and disabilities were found depending on the sport characteristics. Considering the characteristics of the sports is necessary to prevent sports injuries and disabilities.
