Number of sclerotic glomeruli increases during the aging process. Consequently, majority of remained nonsclerosed glomeruli become hypertrophic and some of them sclerotic, too. The aim of this study was to quantify the size and connective tissue content of nonsclerosed glomeruli and to evaluate the percentage of hypertrophic ones in examined human cases during the aging. Material was right kidney's tissue of 30 cadavers obtained during routine autopsies. Cadavers were without previously diagnosed kidney disease, diabetes, hypertension, or any other systemic disease. Tissue specimens were routinely prepared for histological and morphometric analysis. Images of the histological slices were analyzed and captured under 400x magnification with digital camera. Further they were morphometrically and statistically analyzed with ImageJ and NCSS-PASS software. Multiple and linear regression of obtained morphometric parameters showed significant increase of glomerular connective tissue area and percentage. Cluster analysis showed the presence of two types of glomeruli. Second type was characterized with significantly larger size, connective tissue content, and significantly lower cellularity, in relation to the first type. Such glomeruli might be considered as hypertrophic. First type of glomeruli was predominant in younger cases, while second type of glomeruli was predominant in cases older than 55 years.

F1 Generation

Differences in dressing percentage and content of different tissues in carcasses of Domestic Spotted breed and crosses F1 generation with Charolais and Limousine breed were investigated. Total of 30 carcass sides were dissected, 10 in each genetic group. Genotype exhibited very significant effect (p<0,01) on dressing percentage and content of tissues, except for connective tissue. The highest dressing percentage was determined in crosses with Charolais (59,92%) followed by crosses with Limousine (59,85%), with statistically significant difference (p<0,01) to dressing percentage established for heads of domestic Simmental breed (55,71%). Crosses with Charolais and Limousine realized considerably higher content of muscle tissue (81,5% and 80,7%) compared to heads of domestic Simmental breed (77,86%). Content of bone tissue of 16,45% in carcasses of domestic Simmental breed was considerably higher (p<0,01) compared to both groups of crosses, whereas the content of fat and connective tissue was considerably higher (p<0,05) only in relation to crosses with Limousine.

Exposure Measurements

After cold acclimation at 6 °C. white rats have a smaller muscle mass than control animals of the same age kept at 30 °C. Water and protein determinations in soleus and gastrocnemius muscles as well as in the whole muscular mass revealed that the reduction in the muscle mass after cold acclimation is a real tissue difference due to a reduced protein deposition and not only a water content difference. Apparently red and white fibers are equally affected in their growth by the prolonged cold exposure. Measurements of number and size of muscle fibers in soleus cross sections strongly suggest that protein deposition had been reduced in the same proportion in both muscle fibers and connective tissue.

Segments of carotid and tail arteries were used to determine the effects of two-kidney Goldblatt hypertension on mechanical properties and chemical contents. Arteries were obtained after 4 and 12 wk of hypertension. Systolic pressures averaged 129 mmHg in control animals and 150 mmHg in hypertensive ones. Pressure-diameter data were recorded under conditions of active (145 mM K+) and passive (0 Ca2+ and 2 mM EGTA) smooth muscle. Small increases in passive stiffness were found after 4 and 12 wk in the carotid arteries of hypertensive animals, but no significant change occurred in the tail arteries. Small but significant decreases in total connective tissue content of these arteries were found after 12 wk of hypertension. Maximum values of active stress response were significantly larger in carotid arteries from hypertensive animals at both 4 and 12 wk of hypertension. No significant differences were found for the tail arteries. The K+ content of the carotid but not the tail artery was larger for the hypertensive animals. When corrected for differences in relative cell content most of the differences in active force development were eliminated. The differences in passive mechanics can not be explained on the basis of the changes in connective tissue content. The active smooth muscle responses and content changes suggest that they are directly related to the moderate elevation of arterial pressure.
