Antioxidant capacity of Momordica charantia extract and its protective effect on testicular damage in valproic acid-induced rats

Int. j. morphol; 36 (2), 2018
Although Momordica charantia (MC) has preventive effects on tissue injuries, antioxidant capacity and protective effect of MC pulp and peel (MCP) on valproic acid (VPA)-testicular damage have never been reported. Fresh MCPs were aqueous extracted and determined for antioxidant capacity and momordicine I ...

Impact of testicular sperm extraction and testicular sperm aspiration on gonadal function in an experimental rat model

Int. braz. j. urol; 44 (1), 2018
ABSTRACT Purpose To assess the impact of sperm retrieval on the gonadal function of rats with impaired spermatogenesis by comparing testicular sperm extraction (TESE) to aspiration (TESA). The efficacy of these procedures to sperm obtainment was also compared. Materials and Methods A pilot study showed...

Actiflagelin, a new sperm activator isolated from Walterinnesia aegyptia venom using phenotypic screening

Sperm contains a wealth of cell surface receptors and ion channels that are required for most of its basic functions such as motility and acrosome reaction. Conversely, animal venoms are enriched in bioactive compounds that primarily target those ion channels and cell surface receptors. We hypothesized, ...

Comportamiento del semen bovino sexado congelado-descongelado en fertilización in vitro (FIV) capacitado mediante BO en dos concentraciones versus percoll

Int. j. morphol; 35 (4), 2017
RESUMEN: El objetivo fue comparar la tasa de división (TD) y desarrollo embrionario (DE) con semen sexado X (SX) en FIV capacitado con Percoll vs. BO, y evaluar el efecto de dos concentraciones (5x106 vs. 10x106 espermatozoides/ml), capacitado con BO, comparado con el semen no-sexado (NS). Un avance imp...

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...

The quantification of testicular cells during the postnatal development in two Caviomorph rodents: the guinea pig (Cavia porcellus) and the cutia (Dasyprocta agouti)

An. acad. bras. ciênc; 89 (3), 2017
ABSTRACT The germinative, Sertoli and Leydig cells of two caviomorph rodents (Cavia porcellus and Dasyprocta agouti) were counted as well as the estimation of the total volume of the testis and the total volume of seminiferous tubules and interstitium in prepubertal, pubertal and adult animals. The numbe...

Evaluation of sperm quality of Erythrolamprus poecilogyrus sublineatus (Cope, 1860) (Serpentes, Dipsadidae)

Braz. j. biol; 77 (3), 2017
Abstract Erythrolamprus poecilogyrus sublineatus (Cope, 1860), is a species widely distributed in the Pampa Domain, occurring in Rio Grande do Sul, Argentina and Uruguay, mainlyin the pampa region. In the coastal region of southern Brazil this is serpent is considered one of the most abundant. The purpos...

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...
