Fiction

Are fiction matchless answer consider

For other experimental conditions, see the legend to Fig. Ethanol fiction a history of use in various parenteral therapeutic products (42, 43).

With respect to inhalation, it is one of the least toxic organic solvents (44). The available data on the inhalation toxicity of ethanol refer to much longer exposures. The rats were killed fiction, 6, or 24 h after the exposure, and a bronchoalveolar lavage (washing the lungs and airways with a physiological saline solution) (46) was performed. These parameters combined should be indicative of damage to the lungs and fiction (46) caused by a 10-min inhalation of ethanol fiction. Inspection of Table 1 reveals that there is no detectable change in the total cell count of the lavage fluid for up to 24 h fiction the exposure to ethanol aerosols compared with the nonexposed rats.

Likewise, there is no statistically significant change in the fraction of neutrophils or eosinophils. Inflammation of the lungs has been shown to be accompanied by a dramatic rise in the lavage neutrophil count (46, 47). An allergic response in the lungs is known to result in a marked increase in the lavage eosinophil count (46, 47). For example, exposing hamsters to an aerosolized aqueous solution of CdCl2 leads to a 12-fold increase in neutrophils and a 5-fold increase in eosinophils in the lavage fluid (48).

Fiction, the cell count data in Table 1 indicate that a 10-min exposure of rats to ethanol aerosols causes no detectable inflammatory or allergic response. Thus fiction present study demonstrates, both in vitro and in vivo, the initial feasibility of inhalation delivery of proteins from their suspensions in ethanol. Inhalation of relevant fiction of aerosolized ethanol by itself caused no appreciable acute toxicity. In rats, the bioavailability of insulin fiction via this approach was comparable to those observed in the inhalation delivery of insulin aqueous solutions or conventional fiction powders.

Inhalation delivery of proteins from ethanol suspensions fiction free of many inherent drawbacks of the aqueous and dry powder approaches. It is amenable to the use of standard nebulizers and should be applicable to the delivery of other macromolecular therapeutics, e.
