    Nutrition studies of saturation/excursion dives were made in a hyper-baric chamber. Seven divers were investigated during a period of 26-day N2-O2 saturation dive to 36.5m with excursion to 60-75m using only air. Daily intake of food was surveyed by regular weighing method. The caloric and nutrient intakes were calculated from Chinese food composition tables. Urine samples were collected for estimation of vitamin B1, B2, 4-pyridoxic acid, ascorbic acid and also nitrogen. During the dive they lost the appe- tite...

    Nutrition studies of saturation/excursion dives were made in a hyper-baric chamber. Seven divers were investigated during a period of 26-day N2-O2 saturation dive to 36.5m with excursion to 60-75m using only air. Daily intake of food was surveyed by regular weighing method. The caloric and nutrient intakes were calculated from Chinese food composition tables. Urine samples were collected for estimation of vitamin B1, B2, 4-pyridoxic acid, ascorbic acid and also nitrogen. During the dive they lost the appe- tite for meat and oil, instead they preferred vegetables, fruits and beverages. Thus energy, protein and lipid decreased and a weight loss was observed. The urinary excretion of certain vitamins was reduced, especially marked with thiamine. Accordingly a suggestion on the allowance of certain nutrients was proposed.

    在高压舱内进行的36.5米氮-氧饱和空气巡潜60~75米26昼夜中,7名青年男性潜水员的食欲有些变化,喜吃含水量多的食物,使热量与蛋白质摄入量减少,体重下降约1kg,在饱和潜水期间补充了维生素丸,但随着饱和潜水时间的增加,各维生素排出量却逐渐下降,其中硫胺素排出量下降尤为明显,核黄素排出量于饱和潜水中期有一时性增加后也逐渐减少。由于蛋白质摄入量减少,尿氮排出量亦明显下降。文中还对饱和潜水作业人员的一些营养素供给量提出了建议。

Maternal exposure did not appear to influence on the involuntary infertility and out come of pregnancies or the frequency of major congenital abnomalities, but the incidence of pregnancy toxaemia was found to...

    236 female workers exposed to vinyl chloride(VC) and 239 women not exposed to this occupational hazard were examined. The concentrations of VC in workplaces was 1-7 times as the MAC(30mg/M~3) in the examined vinyl chloride polymerization plant and lower in the polyvinyl chloride plastic finishing works. Maternal exposure did not appear to influence on the involuntary infertility and out come of pregnancies or the frequency of major congenital abnomalities, but the incidence of pregnancy toxaemia was found to be higher among the female workers exposed to higher VC. Among 11 pregnant women exposed to VC, the Hb% level and the thrombocyte number were lower than that of the mated control group.The results of animal experiment indicated that the effects of teratogenesis were not found in rats and mice which had been exposed to 5000 ppm VC during pregnancy, however, the embryotoxicity was found. At 10 ppm VC, the embryotoxicity was not appeared. The conception abilities of female animals were not affected at both concentrations.

    本文观察了氯乙烯(VCM)对女工及雌性动物妊娠机能及胎儿(仔)发育的影响。共调查了236名氯乙烯作业女工,其中氯乙烯聚合工厂女工106名,车间空气中氯乙烯浓度经常超过卫生标准1—7倍;聚氯乙烯塑料加工女工130名,车间空气中VCM一般不超过卫生标准;以机械加工女工及女售货员239名为对照。结果为氯乙烯作业女工原发性不孕、自然流产及子代先天缺陷的发病率均不高。但氯乙烯聚合工厂女工的妊振高血压综合征发病较高。第一胎妊娠时的发病率为22.6%,相当于对照组女工的1.8倍。11名妊娠女工妊娠28~29周时,血色素含量及血小板计数低于对照女工(p<0.01)。大、小鼠于妊前2周及整个妊娠期以5000 ppm VCM吸入染毒时均未出现致畸,但胎鼠有皮下出血、骨骼发育迟缓、小鼠胎鼠体重低于对照组(p<0.05)。10 ppm染毒时无此等改变。结果认为女工可以参加空气中VCM浓度低于卫生标准的氯乙烯作业,但须加强对妊娠女工的劳动保护。

    In this study, we selected 24 crewmen who worked in the high temperature circumstances in the engine cabin, resulting in a great loss of body water, together with a large amount of inorganic salts and nitrogen. We Proved that the loss of sodium, potassium, and calcium in sweat is greater than that in urine. The excretion of sodium is the highest, then potassium, the lowest is calcium. The body weight of the engine member has a prominent decrease after summer. It seems that the regaining of body weight can be...

    In this study, we selected 24 crewmen who worked in the high temperature circumstances in the engine cabin, resulting in a great loss of body water, together with a large amount of inorganic salts and nitrogen. We Proved that the loss of sodium, potassium, and calcium in sweat is greater than that in urine. The excretion of sodium is the highest, then potassium, the lowest is calcium. The body weight of the engine member has a prominent decrease after summer. It seems that the regaining of body weight can be promoted by great supply of vitamins. So, we should give a large amount of proteins, vitamins and calcium to the members who worked in the circumstance of such a high temperature. The amount of salt is already quite enough in an ordinary meal.

    本实验观察24名机电人员在高温环境下作业时的结果表明,人体水分、无机盐和氮的大量排失。而且汗中的钠、钾、钙及氮的排失量高于尿液,其中以钠的排失量为最高,钾次之,钙最低。机电人员经过夏季,其体重有明显的降低,但大量补给维生素似有利于促进体重的复升。对高温环境下作业的机电人员,应注意补给大量的蛋白质、维生素及钙等。食盐从膳食中供给可以满足。
