The objective of this study was to investigate rumen fermentation, apparent digestibility of nutrients, and morphology of ruminal und intestinal mucosa in two cattle breeds of different metabolic type. From each breed six purebred German Holstein (H) bulls representing the secretion type and six Charolais (CH) bulls representing the accretion type were raised and fattened under identical conditions with <I>semi ad libitum</I> feeding of a high energy diet. The animals were used for a digestion trial started at nine months of age and animals were slaughtered at 18 months of age. Body weight (668 vs. 764 kg, <I>P</I> = 0.011), body weight gain (1 223 vs. 1 385 g/day, <I>P</I> = 0.043), and body protein gain (93 vs. 128 g/day, <I>P</I> = 0.001) were lower in H compared to CH bulls. Protein expense per kg protein accretion was higher in H bulls (13.8 vs. 10.2, <I>P</I> = 0.001). No significant differences were found in concentration and pattern of ruminal short chain fatty acid and in apparent digestibility of organic matter, crude fibre, and N-free extracts. There were no significant differencs in all morphometric traits of rumen mucosa between both cattle breeds. Compared to H, the villi of CH bulls were higher in duodenum (586 vs. 495 &mu;m, <I>P</I> = 0.001) and proximal jejunum (598 vs. 518&mu;m, <I>P</I> < 0.001), the crypt were deeper in duodenum (295 vs. 358, <I>P</I>< 0.001) and proximal jejunum (292 vs. 344 &mu;m, <I>P</I> = 0.020). In contrast, the villi in ileum were higher in H (522 vs. 471 &mu;m, <I>P</I> = 0.006). The weight of total small intestine, as percentage of total body weight, was 1.1 in H and 0.8 in CH (<I>P</I> = 0.002). The utilization of food crude protein was positively related to the duodenal (<I>P</I> = 0.001) and proximal jejunal villus height (<I>P</I> = 0.003) and to the duodenal crypt depth (<I>P</I> < 0.001) and negatively related to weight of small intestine (<I>P</I> = 0.004). It is concluded, that the higher growth potential and feed efficiency in CH bulls compared to H bulls is not caused by differences in digestion processes, but in size of small intestine, and morphology of small intestinal mucosa. Obviously the duodenum and proximal jejunum of CH bulls adapt to increase the absorptive surface due to the increase in nutrient demand.

Atpase Staining

Fibers in cross sections of human and rat muscle were typed by using histochemical ATPase stains, and the results were compared with those of quantitative enzyme assays of fragments of the same fibers dissected from serial freeze-dried sections. Two enzymes previously used to assess the metabolic type were measured in each case: lactate dehydrogenase and either adenylokinase (human fibers) or malate dehydrogenase (rat fibers). With human fibers there was essentially complete agreement between ATPase staining and the metabolic enzyme assays in distinguishing types I and II fibers. The agreement was less consistent with regard to type IIA and IIB fibers. A number of ATPase type IIC fibers were identified in one human muscle, and were found to fall between ATPase types I and IIA on the basis of metabolic enzyme assay results. Rat-fiber ATPase types I, IIA, and IIB from the plantaris muscle were rather well segregated on a two-dimensional lactate dehydrogenase-malate dehydrogenase grid. In the rat soleus muscle, ATPase types I and IIA fibers were shifted to lower lactate dehydrogenase levels, with IIC fibers interposed between them.

Aim. To study the features of element homeostasis in children and adolescents with different variants of essential arterial hypertension. Methods. The clinical and functional variant of arterial hypertension was established based on the data of 24-hour monitoring of the arterial blood pressure. Investigation of the element content in the blood serum and daily urine was performed using the method of atomic absorption spectrophotometry. The clearance and the excreted fraction of the investigated elements were measured. Results. Revealed was an increase of the content of lead in the blood serum, an increase in lead excretion with urine, an increase in its clearance and excreted fraction in patients with stable arterial hypertension. It has been shown that for children and adolescents with a variety of clinical and functional variants of arterial hypertension characteristic is an excess of the serum content of a toxic element (lead) over the content of an essential element (zinc), and these changes are most pronounced in the group with stable arterial hypertension. In children and adolescents with the increase in arterial blood pressure registered was a decrease in the content of zinc and magnesium in the blood serum, whereas the disturbances of element homeostasis relate to the metabolic type. The increase in the content of copper and calcium in blood serum of patients with high blood pressure is also a manifestation of the metabolic type of element homeostasis disturbances. Conclusion. The increased level of lead in blood serum in combination with its enhanced excretion may be a cofactor in the development of essential arterial hypertension in childhood and adolescence.
