title: Effects of high-dose vitamin C administration on postburn microvascular fluid and protein flux.
abstract: The effects of vitamin C treatment (14 mg/kg/hr) on burn injury were evaluated in the hind paws of 12 mongrel dogs. A lymph duct above one hind paw of each dog was cannulated. Hourly lymph flow rates (QL) and plasma and lymph total protein concentrations were measured before the burn injury and for 6 hours after the burn injury. Data from 24 paws were divided into four groups: nonburn without treatment, nonburn with treatment, burn without treatment, and burn with treatment. The nonburn groups showed no significant differences in QL or in total protein flux. In the burn groups the postburn hourly QL increased by sevenfold in the nontreatment group and only by threefold in the treatment group, whereas the postburn hourly total protein flux increased by fifteenfold and fivefold, respectively. We conclude that administration of high-dose vitamin C reduces early postburn microvascular leakage of fluid and protein.
