ABSTRACT
Twice daily exposure of male rabbits to tobacco smoke inhalation under controlled test conditions led to significant increase of plasma aldosterone as well as angiotensin II. On the other hand, plasma corticosterone and both serum sodium and potassium were not significantly affected. These results were discussed

The effect of chronic exposure of rabbits to hashish smoke every other day for 30 days, was investigated on blood count, plasma lipids and lipoprotein lipase activity. The red cell count as well as the haemoglobin content decreased significantly. The total leucocytic count was not altered, yet the differential count showed a significant rise of polymorphs, together with a significant decrease of lymphocytes. Regarding lipids, the plasma free fatty acids [FFA] and lipoprotein lipase activity decreased significantly, while the total plasma cholesterol and triglycerides did not change. These results were discussed

The effect of daily administration for nine weeks of the natural female sex hormones oestradiol benzoate and progesterone [alone and combined] as well as the synthetic female sex hormones norethisterone and ethinyl oestradiol [alone or combined] on oral iron absorption was investigated in the rabbit and the rat. Oral iron absorption was assessed through the study of post absorption plasma iron tolerance curves [both chemical and radioactive], red blood cell uptake of radio-iron and whole body retention of radio-iron. The results showed that in the rabbit the natural female sex hormones led to a decrease of oral iron absorption. On the other hand, synthetic female sex hormones, norethisterone alone or combined with ethinyl oestradiol, increased oral iron absorption in the rat. Yet the combination of both synthetic female sex hormones did not affect oral iron absorption in the rabbit. These results were statistically analysed and discussed
