目的：观察蓖麻油餐用于晚期妊娠引产的疗效。方法：随机选择１１８例服用蓖麻油餐引产与同期１０６例催产素引产作对照,观察引产效果、产程、产后出血及新生儿评分。结果：观察组引产效率明显高于对照组（Ｐ＜００５）,剖宫产率明显低于对照组（Ｐ＜００５）,两组的产后出血和新生儿阿氏评分无显著性差异（Ｐ＞００５）。结论：蓖麻油引产优于催产素引产。     

烹调油烟对大鼠睾丸毒性的影响

作者探讨了烹调油烟（ Ｃ Ｏ Ｆ）对雄性大鼠生殖性损伤的毒作用机制。按时相（２０、４０、６０天）给雄性 Ｓ Ｄ 大鼠吸入同一浓度（３６～５３ ｍ ｇ／ｍ ３ ）的 Ｃ Ｏ Ｆ,观察 Ｃ Ｏ Ｆ对睾丸及其微量元素的影响。结果表明,吸入 Ｃ Ｏ Ｆ４０、６０天时大鼠体重均有降低趋势;睾丸、附睾脏器及其与体重的比值均分别低于对照组（ Ｐ＜ ００５）,且呈时 效关系;染毒４０、６０天时精子含量和存活率显著降低,而畸形率明显增高,且死精子多;染毒４０、６０天时睾丸中 Ｚｎ、 Ｍｎ 代谢紊乱,出现 Ｚｎ 低, Ｍｎ 高,均呈时 效关系。提示, Ｃ Ｏ Ｆ对性腺具有明显毒性,同时微量元素代谢紊乱可能对性腺的损害起了重要作用。

Effect of a diet rich in linseed oil on complex viscosity and blood pressure in spontaneously hypertensive rats (SHR)

Summary The influence of a diet rich in linseed oil (10 % in weight) with a content of 61.2 % of -linolenic fatty acid on blood pressure and complex blood viscosity was investigated in spontaneously hypertensive rats. A decrease in blood pressure by 59 mm Hg was found compared to the age-matched, untreated control group. The viscous () and elastic () components of viscosity were also reduced at various shear rates ( ). The same applies to the aggregation index, which is a measure of the aggregation tendency of red blood cells (RBC).Of course, the effects on blood viscosity cannot explain the observed degree of blood-pressure lowering. Nevertheless, a decrease in the viscosity can improve the flow conditions in the microcirculation, which may lead to a better oxygen supply.Supported by the Alfred-Teufel-Stiftung.This study is part of the unpublished doctoral thesis of M.

Cutting oil dermatitis on guinea pig skin

The effect of repeated exposure of cutting oil on 8 guinea pigs' skin was evaluated by visual scoring for erythema and skin water vapour loss (SVL) measurement over a 6-week period. The visual scores (measuring severity of erythema) and SVL values were significantly higher on skin treated with cutting oils (positive control) compared to untreated skin (negative control) throughout the study period. The scores and SVL values returned to near-baseline values when cutting oil application was stopped. In addition, the effect of 2 "after-work" emollient creams on 8 guinea pigs' skin repeatedly treated with a cutting oil was assessed by similar methods. The visual scores and SVL values of guinea pig skin that was repeatedly treated with the cutting oil and moisturized with "after-work" emollient creams, were significantly higher than negative and positive control guinea pig skin. It appeared that the 2 "after-work" emollient creams do not alleviate the irritant effect of the cutting oil on guinea pig skin. They appeared to aggravate the irritant effect of the cutting oil.     

Psychological effects of aromatherapy on chronic hemodialysis patients

Effects of aromatherapy (odorless condition, lavender, and hiba oil) on mood and anxiety were investigated in 14 female patients who were being treated with chronic hemodialysis. A control period consisting of natural hospital smells was established before each test session, and then aromatic test conditions were systematically evaluated for odorless conditions as well as aromatic conditions containing lavender and hiba oil aromas. The effects of aromatherapy were measured using the Hamilton rating scale for depression (HAMD) and the Hamilton rating scale for anxiety (HAMA). Hiba oil aroma significantly decreased the mean scores of HAMD and HAMA, and lavender aroma significantly decreased the mean scores of HAMA. The mean scores of HAMD and HAMA in an odorless condition were not significantly different from those of the control conditions. These results indicate that in chronic hemodialysis patients hiba oil is an effective, non-invasive means for the treatment of depression and anxiety, and that lavender alleviates anxiety.
