RESUMO
Certain species of winter migratory waterfowl in San-in District, western Japan, were surveyed for influenza virus from November 1983 to March 1984. Faeces of the waterfowl were collected regularly at five stations. Eleven influenza A viruses including H5N3 and H10N4 subtypes were isolated from 450 faecal samples from whistling swans, 28 viruses including H2N2 and H10N4 subtypes were isolated from 362 faecal samples from pintails; and subtype H13N6 was isolated from 240 faecal samples of black-tailed gulls.

From November 1982 to March 1983, winter migratory waterfowls of some species staying in San-in District, Western Japan, were surveyed for influenza virus at five stations. A total of eight influenza A viruses were isolated from 354 faeces samples of whistling swans; in contrast, no virus was isolated from any sample of 261 black-tailed gulls, of 113 pintails and of 10 mallards. Five of eight isolates belonged to human pandemic subtype H2N2, two isolates belonged to fowl plague subtype H7N7, and the remaining one to subtype H4N6.

Manic-depressive states caused by drugs and various diseases consist of symptomatic psychosis, organic psychosis and toxic psychosis. Disturbance of consciousness is common to symptomatic psychosis. Emotional disturbance is associated with it. Dementia, personality change and disturbance of consciousness are common to organic psychosis. Emotional disturbance is also associated with these. Drug-induced manic-depressive states are classified by some studies. Drug-induced manic-depressive states are often caused by drugs for physical diseases. They are not originally psychotropic drugs. And they have affinity to the central nerve system, to some degree. Interferons cause disturbance of consciousness or delirious state in the acute phase and depressive state or numerous psychiatric symptoms in the chronic phase.
