Pericardial metastases are frequently found and often cause cardiac tamponade which requires emergency treatment. Pericardiocentesis or subxiphoid pericardiotomy and pericardial drainage can be performed; the latter is a safe and effective method for the management of continuous pericardial effusion since it can be done under direct visualization and local anesthesia. ⋯ If the patient with malignancy is attacked by cardiac tamponade, subxiphoid pericardiotomy and pericardial drainage should be performed considering neoplastic cardiac tamponade. We have described pathophysiology, diagnosis and treatment of neoplastic cardiac tamponade.

[Law, guidelines and standards relevant to laboratory animals and animal experimentation].
Presently available laws guidelines and standards relevant to laboratory animals and animal experimentation are reviewed. In Japan there exist Animal Protection and Management Act, and the Guideline for Animal Care and Management which was later prepared in accordance with the former act. These are comparable in quality to those seen in foreign countries such as the Cruelty to Animals Act of Great Britain or the Animal Welfare Act of U. ⋯ As for laboratory animals, however, only basic matters appear there, and that is why the Japanese National Academy of Science in 1980 proposed legislation of a guideline for animal experimentation to the government. It is awaited to legislate sooner the one comparable to the Guidelines for the Regulation of Animal Experimentation prepared by ICLA in 1974. Other laws and regulations referred and discussed here are: *standards and guidelines for breeding, care and management of laboratory animals *veterinary laws and regulations which should be referred when domestic or wild animals are to be used for experiments *laws and regulations for general housing construction and environmental protection *regulations for particular experiments where radioisotopes, microbial infections or recombinant DNA are in use

Comparative Study Clinical Trial Controlled Clinical Trial[Effect of a long-acting analgesic, buprenorphine on cancer pain--a single-blind crossover comparison with pentazocine].
The therapeutic value of buprenorphine was investigated in 31 patients suffering from moderate to severe cancer pain by intramuscular administration at the single doses of 0.2 mg and 0.3 mg in comparison with pentazocine 30 mg. Analgesic effect of buprenorphine 0.3 mg was significantly superior to buprenorphine 0.2 mg and pentazocine 30 mg. The duration of analgesia with buprenorphine was 9 hours at 0.2 mg and 11 hours at 0.3 mg, which were markedly longer than pentazocine's 6 hours. ⋯ Blood pressure, heart rate and respiratory rate did not change appreciably, thereby suggesting a little effect of buprenorphine on the respiratory and cardiovascular systems. Buprenorphine was found a useful or extremely useful in 58% at 0.2 mg and 87.5% at 0.3 mg. As the result it was concluded that buprenorphine could be valuable as an analgesic for cancer pain.
