The presence of D-glucuronic acid in dermatan sulfate preparations has previously been reported from several laboratories. It has not been clear whether the D-glucuronic acid represents a contamination with another polymer or whether it is actually part of the dermatan sulfate molecule. The present studies were undertaken in order to evaluate this problem more definitively. It is demonstrated t...

Testicular torsion is a urological emergency that leads to serious testicular damage and male infertility. We performed this study to identify specific proteins that are differentially expressed in response to testicular torsion and detorsion-induced ischemia-reperfusion (I-R) injury. Adult male rats were divided into two groups: a sham-operated group and a testicular I-R group. Testicular tors...

The aim of this study was to gain insight into the quality of life (QoL) and stress response of female spouses of men cured of testicular cancer in the long-term. Time since treatment completion varied from 0.5 to 23.8 years. Two hundred and fifty nine testicular cancer survivors and their spouses completed the Dutch version of the MOS Short Form (SF)-36 and the Impact of Event Scale. QoL data ...

This research aims to study testis and epididymis of dry land goat (Capra hircus) on B-mode ultrasound imaging. Twelve adult local male goats were examined normal testes ultrasonic appearances. real time scanner with a 7.5 MHz, linear array transducer was used evaluate the echotexture testicular parenchyma, mediastinum epididymis. The parenchyma represented uniformly homogenous moderately echog...

OBJECTIVE To study the incidence of testicular and epididymal appendages in patients with cryptorchidism. MATERIALS AND METHODS We studied 65 patients with cryptorchidism, totalizing 83 testes and 40 patients who had prostate adenocarcinoma and hydrocele (control group), totalizing 55 testes. The following situations were analyzed: I) absence of testicular and epididymal appendages, II) prese...

PURPOSE To compare the structure of the testis in fetuses with prune belly syndrome (PBS) to normal controls. MATERIALS AND METHODS We studied 6 testes obtained from 3 fetuses with PBS and 14 testes from 7 male fetuses. The testicular specimens were cut into 5-μm thick sections and stained with hematoxylin and eosin (HE), to observe the seminiferous tubules; Weigert's solution to observe elas...

Advances in two techniques have made the problem of assessing the acute and/or chronic effects of toxic agents on Leydig cell structure and testosterone synthesis and secretion amenable to study. First, in vitro testicular perfusion has been perfected to a point where it closely resembles in situ testosterone secretion. Second, now it is possible to quantify the proportion of Leydig cell cytopl...
