Responses of growth rates and growth hormone levels of African catfish (Clarias gariepinus) to stocking density
In order to estimate responses of growth rate and growth hormone of Clarias gariepinus to stocking density, fish (initial weight 30.71 ± 0.89 g) were stocked in 120-L tanks at densities of 35, 65, 95, and 125 kg/m3 for 60 days. On day 30 and 60, the fish growth rates were measured, pituitary growth hormone (GH) mRNA levels and serum GH concentrations were examined by real-time qPCR and ELISA te...
متن کاملVentilatory Responses of Children to Changes in Deadspace Volume
Alveolar deadspace is greater during anaesthesia than in the conscious state (Nunn and Hill, 1960), and during spontaneous ventilation it increases with depth of anaesthesia (Kain, Panday and Nunn, 1969). However, although the additional influence of apparatus deadspace was investigated by Kain, Panday and Nunn (1969), few studies have considered the effects of apparatus deadspace on anaestheti...
متن کاملVentilatory and perceptual responses to cycle exercise in obese women.
The main purpose of this study was to examine the relative contribution of respiratory mechanical factors and the increased metabolic cost of locomotion to exertional breathlessness in obese women. We examined the relationship of intensity of breathlessness to ventilation (VE) when exertional oxygen uptake (VO2) of obesity was minimized by cycle exercise. Eighteen middle-aged (54+/-8 yr, mean+/...
متن کاملVentilatory responses to ozone are reduced in immature rats.
During ozone (O(3)) exposure, adult rats decrease their minute ventilation (VE). To determine whether such changes are also observed in immature animals, Sprague-Dawley rats, aged 2, 4, 6, 8, or 12 wk, were exposed to O(3) (2 ppm) in nose-only-exposure plethysmographs. Baseline VE normalized for body weight decreased with age from 2.1 +/- 0.1 ml. min(-1). g(-1) in 2-wk-old rats to 0. 72 +/- 0.0...
متن کاملVentilatory responses to specific CNS hypoxia in sleeping dogs.
Our study was concerned with the effect of brain hypoxia on cardiorespiratory control in the sleeping dog. Eleven unanesthetized dogs were studied; seven were prepared for vascular isolation and extracorporeal perfusion of the carotid body to assess the effects of systemic [and, therefore, central nervous system (CNS)] hypoxia (arterial PO(2) = 52, 45, and 38 Torr) in the presence of a normocap...
