Hematotsticular in rats with liver cirrhosis: Our data revealed that prenatal water deprivation resulting increase in vacoulation, detachment, degeneration of the germinal epithelium of seminiferuos tubules and also increasing number of TUNEL positive cells showed induction of germ cell apoptosis.

Este receptor es muy parecido al receptor de la insulina. Cooperative study on alcoholic hepatitis VI. Further clinical trials are needed to identify adequate IGF-I doses, administration duration and frequency, and the subgroup of cirrhotic patients who will benefit most from this replacement therapy. Cirrhotic liver expresses low levels of the full-length and truncated growth hormone receptors.

Pflugers Arch ; Expression of insulin-like growth factor I by activated hepatic stellate cells reduces fibrogenesis and enhances regeneration after liver injury. IGF-I does not improve fat malabsorption in cirrhotic rats.


The insulin-like growth factor I receptor: It is partly responsible for GH activity, and also hdmatotesticular glucose-lowering and anabolizing effects. N Engl J Med ; Maternal stress alters endocrine function of the feto-placental unit in rats.

Insulin-like growth factor-I lowers protein oxidation in patients with thermal injury. Alcohol Alcoholism ; 24 4: On the other hand we previously showed that testosterone decreased following water deprivation.

Volver a congelar tejidos embebidos en el hielo seco puede aumentar la rigidez para el corte. Altered liver gene expression in CCl4-cirrhotic rats is partially normalized by insulin-like growth factor-I.

The transit of glucocorticoids from blood testis barrier, apoptotic effect of these compounds on the central nervous system that affect HPA axis in accompany with changing in regulatory receptors of testicular tissue are three possible pathways of hemstotesticular of prenatal stress on spermatogenesis.

TUNEL assay was also performed for showing the occurrence of apoptosis in the testes. In experimental animals, water was removed from the ewes for 48h at the end of third trimester of gestation th days.


In vitro experiments were performed in order to analyze effects of IL17A on Sertoli cell tight junctions. Toxic effects of dexamethason on mous testicular germ cell. Some cirrhosis complications, mainly those nutritional and metabolic in nature insuline resistance, malnutrition, osteopenia, hypogonadism, intestinal disordersmay be at least partly related to this Hematoteeticular deficiency, since some IGF-I effects represent a reverse image of cirrhosis complications.

No death was observed among two groups during the period of the study. The testes were removed and weighed.
