The oviduct is a vital organ for the process of capacitation, sperm survival and insemination. Gametes are transported, embryo formed in it. article has described morphological features studied morphometric parameters goats during newborn period, 5-, 6-, 7-months-old adult animals. Since period to age 5 months, oviducts female grow at relative rate 109.6%. From this adulthood, growth averages 2...

The effects of glucagon, adrenalin or rapamycin on glycogen autophagy in the liver and heart of newborn rats were studied using biochemical determinations and electron microscopy. Glucagon or adrenalin increased autophagic activity in the hepatocytes and myocardiocytes, glycogen-hydrolyzing acid glucosidase activity in the liver and heart and degradation of glycogen inside the autophagic vacuol...

We tested the hypothesis that targeted transgenic overexpression of human extracellular superoxide dismutase (EC-SOD) would preserve alveolar development in hyperoxia-exposed newborn mice. We exposed newborn transgenic and wild-type mice to 95% oxygen (O2) or air x 7 days and measured bronchoalveolar lavage cell counts, and lung homogenate EC-SOD, oxidized and reduced glutathione, and myelopero...

By intensive stimulation with large amounts of Salmonella flagellar antigen, newborn rabbits were induced to form high titer flagellar agglutinins usually by the 7th to 10th day of life. Characterization of the agglutinins at various times during the first 30 days of life revealed that the earliest antibody which appeared was a gamma-1 macroglobulin, and that 7S gamma-2 globulins did not appear...

In the liver tissue of newborn mice, xanthine oxidase activity is very low during the first 7 to 14 days of life. Infection of mice with several different viruses prematurely induced xanthine oxidase activity 2- to 10-fold in the liver tissue. Generally, overt signs of illness appeared after xanthine oxidase induction; however, some viruses induced the enzyme activity without causing morbidity ...

South American subterranean rodents are mainly described as solitary and mutual synchronization was never observed among individuals maintained together in laboratory. We report that a single birth event was capable of disrupting the robust nocturnal activity rhythm of singly housed tuco-tucos from north-west Argentina. "Around-the-clock activity" was displayed by 8 out of 13 animals whose cage...

This study was done after identifying animals with a twisted carpal joint in goat herd. These included a kid goat walking on its articulus carpii and a newborn goat with a stiff leg. Necropsies of the diseased goats revealed swollen carpal joints that were twisted backwards. Arthritis was observed during microscopic examination of the carpal joints. Very low levels of eosinophil, leucocyte, and...

During the individual development and exposure to infectious agents of organism, structural components thyroid gland can change significantly. In modern research, great importance is attached study mechanisms for maintaining morphological homeostasis ideas about its functional restructuring in response body's immune system various infections. The morpho-functional features newborn animals after...
