Testicular blood flow and plasma testosterone concentrations in anesthetized rats previously exposed to air at 6 ATA
plasma testosterone animal rat air Testicular
2009/7/17
Testicular blood flow and peripheral testosterone levels were measured in sodium pentobarbitone anesthetized adult rats within 3 h of exposure to air at 6 ATA for 24 h. The animals appeared clinically...
Influence of increased gas density and external resistance on maximum expiratory flow
human respiratory lung pressure
2009/7/17
The effect of external resistance on the relationship of expiratory air flow and intrathoracic and mouth pressure on subjects breathing gas of increased density was investigated. Five subjects breathi...
