Input: Consider Input: Abstract: The distribution of whole-body O2 supply during severe hypoxia and recovery and its relation to the regional distribution of O2 deficit and repayment was studied. Mongrel dogs were anesthetized, paralyzed, and ventilated to maintain an end-tidal PCO2 between 35 and 40 Torr. In one group, the alpha- and beta-adrenergic receptors were blocked to eliminate neural and humoral adrenergic influences. In a second group, alpha-adrenergic receptors were stimulated to decrease O2 delivery by excessive vasoconstriction. In a third group, beta-adrenergic receptors were stimulated to increase O2 delivery. Whole-body and hindlimb muscle O2 uptake and vascular responses were measured during normoxic control, 15 or 30 min of severe hypoxia (9% O2 in N2), and 20 or 30 min of normoxic recovery, respectively. The whole-body O2 deficit and excess O2 uptake in recovery were partitioned into muscle and nonmuscle areas. The data showed that neural or humoral influences had little effect on the regional distribution of the total O2 deficit and O2 excess in recovery. The O2 deficit could be decreased somewhat by increasing delivery, but the amount of excess O2 used in recovery was unaffected. This suggested that the excess O2 use in recovery was more a function of an energy deficit during hypoxia and not an O2 deficit.

Output: Adrenergic and local control of O2 uptake during and after severe hypoxia.

Input: Consider Input: Abstract: In an attempt to improve speech results following palate repair while allowing adequate maxillary growth, a palatoplasty using two opposing Z-plasties of the soft palate, one of the oral and one of the nasal layers, has been used in 22 infants. Eight patients had unilateral cleft lip and palate, eight had bilateral cleft lip and palate, and six had cleft palate. The Z-plasties facilitate effective dissection and redirection of the palatal muscles to produce an overlapping muscle sling and lengthen the velum without using tissue from the hard palate, which permits hard palate closure without pushback or lateral relaxing incisions. Of the 20 children old enough for speech evaluation, 18 have no velopharyngeal insufficiency. Two have very mild velopharyngeal insufficiency. None has required a pharyngeal flap.

Output: Cleft palate repair by double opposing Z-plasty.

Input: Consider Input: Abstract: In an effort to determine whether life in industrialized societies can have an effect on hearing, 90 natives from Easter Island over 45 years old were evaluated. They underwent complete clinical and audiological assessment and were divided into groups according to those having lived only on the island or those having lived in modern civilization. With all factors being equal, except exposure to modern civilization, our results showed that living in civilized societies has a significant negative effect on hearing; the severity is directly proportional to the years of exposure. The median hearing thresholds of natives always living on the island (men and women combined) was found to be similar to those of female citizens of the United States; there was no significant difference in hearing thresholds between men and women among these natives. These results suggest that there are no significant inherent racial differences nor significant inherent differences between males and females in the sensitivity of hearing. A relationship between aging and hearing was noted and interpreted as true or intrinsic presbycusis. There were no cases of otosclerosis, Meniere's disease, or exostoses of the external ear canal among natives who had always lived on the island. Pure natives were found not to be prone to otitis media in spite of having an extremely high incidence of severe upper respiratory tract allergies.
Output: Effect of life in industrialized societies on hearing in natives of Easter Island.
