SASAKI, R., MORISRLTA, T. and YAMAGATA, S. Estimation of the Cell Number of Heart Muscle in Experimental Cardiac Hypertrophy. Tohoku J. exp. Med., 101 (2), 147-152 •\ The total numbers of heart muscle cells and of interstitial cells were estimated in the Goldblatt rats by a histometrical method. The thickness of muscle fibers and the length of muscle cells were also estimated. The heart weight ...

background: there is not enough information about theeffects of heat stress and photoperiod on different lobes structure.objectives: the present study aims at determining thehistological changes and the rate of changes in each lobes of ratprostate, affected by photoperiod changes and heat stress.methods:to this end, 15 adult male wistar rats were divided tothree groups: 1. the control group in ...

Castrated male Iberian (n = 12) and Landrace × Large White (n = 12) pigs were used to study histological structure and enzymatic activity in the small intestine at 3 points of the productive cycle (BW = 15, 50, and 115 kg). Both strains were fed the same cereal-based diets (DE = 2,799 kcal·kg(-1), and CP = 15%) throughout the entire experimental period. Differences (P < 0.05) in histometrical v...

phenol is widely used in numerous non prescription products and the aim of present study was to investigate the dose- dependent effects of phenol on morphometrical and histometrical changes of kidney in an animal model. for this experiment, 60 adult female balb/c mice were weighed, and categorrzed as one control and three experimental groups of 15 individuals each. control group, received only ...
