Inductive role of sustentacular cells (Sertoli cells) conditioned medium on bone marrow derived mesenchymal stem cells

Int. j. morphol; 35 (4), 2017
RESUMEN: Las células madre de la línea germinal masculina son factores clave para la espermatogénesis masculina y la fertilidad. Las células sustentaculares (células de Sertoli) como células somáticas juegan un papel fundamental en la creación de un microambiente esencial para la auto-renovación...

Potential radioprotective effect of AT1 receptor antagonists against morphological and ultrastructural changes in the testes induced by ionizing radiation

Int. j. morphol; 35 (3), 2017
Radiotherapy is a source of human exposure to ionizing radiation. This pure energy causes deleterious effects on tissues, which result from oxidative stress, a phenomenon in which there is the participation of the Renin-Angiotensin System (RAS). The male genital organs are extremely radiosensitive and th...

Protective effect of Momordica cochinchinensis (L. ) spreng aril extract on essential testicular markers in rats induced with valproic acid

Int. j. morphol; 35 (3), 2017
Valproic acid (VPA), an anti-epileptic drug, has been reported to cause male sub/infertility. Together with searching for alternative treatments, the degrees to which testosterone levels and sperm quality are decreased under VPA treatment also need to be clarified. This study aimed to investigate the pro...

Organophosphorous pesticides: their effects on biosentinel species and humans: control and application in Chile

Int. j. morphol; 35 (3), 2017
The environment is negatively affected by the increasing accumulation of both natural and man-made waste and by-products. Organophosphorous pesticides -malathion, diazinon and methamidophos- are used worldwide in pest control. The aim of this report is to review the effects of organophosphates on the mal...

Effects of folic acid administration on testicular ischemia/reperfusion injury in rats

Acta cir. bras; 32 (9), 2017
Abstract Purpose: To determine the effect of folic acid (FA) on experimental testicular ischemia/reperfusion (I/R) in rats. Methods: Sixty male Wistar rats were randomly divided into 6 groups. The control group received physiologic saline orally. The sham-operated group received physiologic saline oral...

Antioxidant and hypoglycemic effects of Momordica cochinchinensis Spreng: (Gac) aril extract on reproductive damages in streptozotocin (STZ)-induced hyperglycemia mice

Int. j. morphol; 35 (2), 2017
The aim of present study was to investigate the effect of Momordica cochinchinensis (Gag) aril (GA) aqueous extract on male reproductive system of streptozotocin (STZ)-induced hyperglycemia (HG) mice. GA were extracted with distilled water (DW) and analyzed for in vitro antioxidant capacities. ICR male m...

Influence of prolonged flaxseed ( Linum usitatissimum ) consumption over epididymis and testicle histoarchitecture of Wistar rats

Pesqui. vet. bras; 37 (6), 2017
Flaxseed is considered a functional food with several health benefits. However, because of its high phytoestrogen content, flaxseed influences hormone metabolism and affects the gonadal biomorphology. In this study, computerized histomorphometry was used to evaluate seminiferous and epididymal tubules, c...

Comparison of sexual performance and testicular characteristics of melatonin treated Kivircik and Charollais rams during the non-breeding season

This study was conducted to investigate the effects of melatonin implantation on basic testicular characteristics and reproductive performance of Kivircik and Charollais rams and ewes during the non-breeding season. In this study, 8 Kivircik and 6 Charollais rams were used. Rams were implanted with 54 mg...

Terminal bifurcation and unusual communication of left testicular vein with the left suprarenal vein

J. vasc. bras; 16 (2), 2017
Abstract Variations of the testicular veins are relevant in clinical cases of varicocele and in other therapeutic and diagnostic procedures. We report herein on a unique variation of the left testicular vein observed in an adult male cadaver. The left testicular vein bifurcated to give rise to left and r...
