Premature rupture of membranes is the most common complication of pregnancy. The incidence of premature rupture of membranes in pregnancy ranged from 6% to 10%, and 20% of these cases occur before 37 weeks gestation. The incidence of premature rupture of membranes in Indonesia ranges from 4.5% to 7.6% of all pregnancies. This research was conducted to determine the cross-sectional differences in the blood plasma levels of vitamin C in term pregnancy premature rupture of membranes with blood plasma levels of vitamin C in term pregnancy without premature rupture of membranes in M. Jam- il Padang hospital, Achmad Muchtar Bukittinggi hospital, and Pariaman Hospital. There are significant differences in vitamin C blood plasma levels in term pregnancy with premature rupture of membranes and term pregnancy without premature rupture of membranes ( P < 0.05). Mean levels of vitamin C in blood plasma at term pregnancy with premature rupture of membranes lower than in the blood plasma levels of vitamin C in term pregnancy without premature rupture of membranes.Keywords: Premature rupture of membrane in aterm, blood plasma levels of vitamin C

In Blood Plasma

Estrone sulfate, estrone, and estradiol-17β have been assayed in blood plasma taken from the mammary vein of five pregnant cows before and after parturition. While there were considerable individual variations, the mean plasma levels of estrone sulfate (13.4 ng/ml), estrone (1 ng/ml) and estradiol-17β (1 ng/ml) remained fairly constant over the period of blood collection prior to parturition (−88 h to −2 h). The levels of all three estrogens dropped rapidly within 8 h postpartum. It is concluded that estrone sulfate, rather than estrone, is the predominant plasma estrogen in late pregnancy in the cow.

Dogs differ from other species with respect to the occurrence of a high percentage of retinyl esters in blood plasma and the excretion of substantial amounts of vitamin A in the urine. Our investigation focussed on the effects of different concentrations of vitamin A in the diet, ranging from concentrations below NRC requirements of 25 IU/kg body weight (BW) to 2400 IU/kg BW, on the levels of retinol and retinyl esters (palmitate/oleate and stearate) in canine blood plasma and urine. The plasma levels of retinyl esters paralleled the levels of vitamin A in the feed (r = 0.91; p < 0.001). The highest plasma level (12.1 ± 0.4 mg/l) was observed at the highest level in the diet. This observation may be explained by the fact that in dogs retinyl esters are associated with lipoproteins. Even under prolonged feeding on vitamin A levels below NRC requirements, retinyl esters were still present in the plasma (2.8 ± 0.1 mg/l). Levels of retinol were not affected (1.2 ± 0.03 vs. 1.0 ± 0.03 mg/l, respectively). In the urine, the concentration of retinol and retinyl palmitate/oleate increased with the first increase of vitamin A in the diet to 1.2 ± 0.4 mg/l of total vitamin A. Urinary levels were elevated and fluctuated with up to four peaks while dietary vitamin A levels were above NRC requirements. But the amount of retinol and retinyl esters excreted did not show any dependence on the amount of vitamin A in the diet. When the amount of vitamin A in the diet was at or below requirements, only traces of retinol and retinyl esters were detected in urine. Thus, contrary to current knowledge for most other mammals, retinyl ester levels in plasma and retinol and retinyl esters in the urine of dogs proved to be clearly but differently affected by the amount of vitamin A supplied with the diet. Contrary to retinol, plasma levels of retinyl esters closely reflect the actual supply of vitamin A with the feed. The occurrence of retinol and retinyl esters in urine may, however, be due to dietary supply of vitamin A in excess of standard requirements, thereby providing a useful indicator of a dietary supply of vitamin A above requirement. The mechanism involved in the possible regulation of urinary excretion of retinol and retinyl esters remains to be elucidated.

Interaction of Se supplementation with sulphur and magnesium in blood plasma were studied in dairy cows. Cows were divided into three groups: (1) control, no treatment; (2) cows injected intramuscularly 21–10 d prior to parturition with 45 mg Se and 2040 IU of vitamin E; (3) cows intraruminally administered with two 30-g pellets containing 10% elemental Se 2 mo prior to expected calving. There were no significant effects of Se supplementation on the plasma levels of sulphur and magnesium. Key words: Selenium, sulphur, magnesium, blood, cattle

When exposed to noise and vibration in experimental animals there was a decrease in the content of threeiodinethyronine, thyroxin and adrenocorticotropic hormone in blood plasma after 15 and 30 days of experience. An increase in loads led to an increase in the level of threeiodinethyronine and thyroxin under vibration exposure and was normalized with noise. The content of adrenocorticotropic hormone leveled in both cases.
