Nutritional and environmental factors are now known to affect the blood pressure and pulse rate of man. The present study investigated the effect of nicotiana tabacum on these parameters. Thirty-three male Nigerians (20-68 years) living in Calabar, Nigeria were used for this study. The subjects were treated at three different periods with snuff containing varied concentrations of Natron (0.5g and 10g/100g of snuff) and their systolic and diastolic pressures as well as pulse rate were measured at intervals of 30 minutes up to a maximum of 90 minutes. Each subject served as his own control. There were significant and time-dependent increases in the parameters measured. In addition, the increases were more marked in the absence of Natron than in its presence.
现在已知营养和环境因素会影响人类的血压和脉搏率。本研究调查了烟草对这些参数的影响。本研究使用了33名居住在尼日利亚卡拉巴尔的男性尼日利亚人（20 - 68岁）。在三个不同时间段，让这些受试者使用含有不同浓度泡碱（每100克鼻烟含0.5克和10克泡碱）的鼻烟进行处理，并每隔30分钟测量他们的收缩压、舒张压以及脉搏率，最长测量时间为90分钟。每个受试者自身作为对照。所测参数出现了显著的且随时间变化的增加。此外，在不含泡碱的情况下，这些增加更为明显。
