title: [Natural killer activity in a viral infection in patients with chronic obstructive bronchitis].
abstract: A study was made into the natural killer (NK) cells reaction to viral infection in those patients presenting with chronic obstructive bronchitis (COB). During acute viral infection (AVI) the COB patients' NK cells were found out to be activated in spite of a decline in their functional capabilities but to a slighter degree than they were in healthy subjects. COB patients failed to be provided with adequate antiviral defence during AVI since the virus was still detectable in many of them in the presence of a decline in NK cells activity, clinical improvement, and even during remission.
