A single total-body exposure of rats to gamma-rays in an absolutely lethal dose caused significant changes in the activity of fructosodiphosphate aldolase (ALD) and glucose-6-phosphate dehydrogenase (G-6-PDH) in the brain, liver, myocardium and skeletal muscles. The activity of ALD was mainly inhibited and that of G-6-PDH increased. Thus, the initial step of glycolysis was significantly inhibited and the key reaction of the pentose phosphate pathway enhanced in the irradiated body. 相似文献

The bacterial gene of the thermostable endo-beta-1,4-glucanase (cellulase) was shown to retain its activity and substrate specificity when expressed in transgenic tobacco plants. The leader peptide of the carrot extensin was efficient in transferring the bacterial enzyme into the apoplast. The expression of the bacterial cellulase gene leads to changes in the plant tissue morphology. In the transgenic plant lines, regeneration of primary shoots from callus occurred at the three to five times higher cytokinin (6-BAP) concentration than in control plants. The transgenic plants that expressed the bacterial gene exhibited increased business and altered leaf shape. The transgenic plants developed can be used as models for studying the cellulases role and function in plants. 相似文献

Generalised obesity is increasing in prevalence globally, however trends in abdominal obesity are less well known. In 2003, 1,999 women of childbearing age participated in the Croatian Adult Health Survey, of whom 598 (29.9%) participated in the second cycle in 2008. For 2008, the prevalence of abdominal obesity using the International Diabetes Federation (IDF) criterion (waist circumference > or = 80 cm) was estimated at 70.3% (95% CI 61.8% to 75.7%), whereas the prevalence of abdominal obesity using the National Cholesterol Education Program, Adult Treatment Panel III (NCEP ATP III) criterion (waist circumference > or = 88 cm) was estimated at 48.6% (42.6% to 54.7%). The preceding five-year cumulative incidence was 54.3% (44.5% to 64.2%) and 35.2% (28.0% to 42.4%) using the IDF and NCEP ATP III criteria, respectively. The burden of abdominal obesity is high and rapidly increasing in Croatian women of childbearing age, the key population subgroup for obesity control. 相似文献

Based on repeated measurement of health behaviors the CroHort Study showed that health behavior explains a great deal more of class inequalities in mortality than observed in previous studies. These include decreasing prevalence of smoking and increase in obesity, hypertension and diabetes mellitus. The lowest prevalence of health risks was recorded among children and adolescents, followed by general adult population from the CroHort Study. Hospitalized coronary heart disease patients had higher risks prevalence than general population, while the highest prevalence of risks was recorded among patients in cardiac rehabilitation program. The higher levels of stress were associated to lower financial conditions, poorer social functioning and poorer mental health for both men and women. Higher levels of stress were also associated with heart problems, higher alcohol consumption in men while in women stress was associated to poorer general health, higher age and lower levels of education. 相似文献

In vitro studies were performed of hypothalamic testosterone (T) metabolism 30 days after castration of adult male rats. No changes were seen in T conversion into dihydrotesterone and estrogens in the castrated rats. Plasma T levels were decreased while plasma estradiol concentrations did not differ from those of intact controls. It was suggested that the hypothalamic T metabolism probably is not androgen dependent. 相似文献
