OBJECTIVESTesticular toxicities of antimony compounds were evaluated in rats and mice. The slightly water-soluble antimony compound antimony trioxide (ATO) and the highly water-soluble antimony compound antimony potassium tartrate (APT) were examined.
METHODSDaily doses of the compounds were 27.4, 12.0 and 1,200 mg/kg body weight in the APT group, low-ATO group and high-ATO group, respectively. The corresponding daily doses of antimony were 10, 10 and 1,000 mg/kg body weight, in the APT group, low-ATO group and high-ATO group, respectively. Both compounds were administered by gavage: rats, 3 days per week for 4 weeks; mice, 5 days per week for 4 weeks.
RESULTSNeither compound reduced the weights of reproductive organs or accessory sex organs nor affected sperm parameters. Few marked histopathologic changes were found in the testes of the treated animals. Even at 1,200 mg/kg body weight, which is greater than the LD(50) of APT, ATO produced no effects.
CONCLUSIONSIn this study, it was found that ATO and APT are not toxic to testes in rodents.

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.
