OBJECTIVE
The salutary effects of the testosterone receptor antagonist flutamide on the depressed immune and cardiovascular functions after hemorrhage and resuscitation are related to improved endothelial cell function, which can subsequently lead to an increase in organ blood flow, oxygen delivery,
BACKGROUND
The vasodilatator effects of testosterone have been widely studied and demonstrated. Based on previous studies of these vasodilatatory activities, we hypothesized that testosterone might have potential effects on subarachnoid hemorrhage-induced cerebral vasospasm.
METHODS
Thirty-two adult
OBJECTIVE
To determine whether testosterone depletion in males before trauma-hemorrhage has any salutary effects on cardiac performance after hemorrhage and resuscitation.
BACKGROUND
Studies indicate that castration of male mice before trauma-hemorrhage prevents the immunodepression seen after
Although studies have shown that testosterone receptor blockade with flutamide after hemorrhage restores the depressed immune function, it remains unknown whether administration of flutamide following trauma and hemorrhage and resuscitation has any salutary effects on the depressed cardiovascular
Although immune functions are markedly depressed in males and not in proestrous females following trauma-hemorrhage (T-H), the mechanisms responsible for the divergent responses remain unknown. Because sex steroids modulate the activation of p38, our aim was to determine whether differences in the
BACKGROUND
A Sri Lankan girl with hereditary hemorrhagic telangiectasia (Osler-Weber-Rendu syndrome) is described.
METHODS
She presented with recurrent spontaneous epistaxis, pulmonary arterio venous malformation and oral telangiectasia. A diagnosis of Hereditary hemorrhagic telangiectasia
Studies indicate that, whereas immune functions in males are depressed, they are enhanced in females after trauma hemorrhage. Moreover, castration of male mice (i.e., androgen depletion) before trauma hemorrhage prevented the depression of cell-mediated immunity. Nonetheless, it remains unknown
Although the testosterone receptor antagonist flutamide restores the depressed immune function in males after trauma and hemorrhage, it remains unknown whether this agent has any salutary effects on adrenal function. To study this, male rats underwent laparotomy and were bled to and maintained at a
BACKGROUND
We tested the hypothesis that testosterone depletion or blockade in male rats protects against trauma hemorrhagic shock-induced distant organ injury by limiting gut injury and subsequent production of biologically active mesenteric lymph.
METHODS
Male, castrated male, or flutamide-treated
BACKGROUND
Recent studies suggest that androgen depletion by castration before hemorrhage has protective effects on cell-mediated immunity in male mice after soft tissue trauma and hemorrhagic shock.
OBJECTIVE
To determine whether treatment with an androgen receptor blocker (eg, flutamide) after
BACKGROUND
Previous studies indicate that after severe hemorrhage, immune functions are markedly depressed in males, whereas females do not show any depression. Although androgen depletion by castration of mice before soft-tissue trauma and hemorrhagic shock prevents the depression of cell-mediated
Background: Previous studies have cross-sectionally described amenorrhea in cohorts of transgender men on intramuscular or subcutaneous testosterone injections. It remains uncertain which testosterone preparations most effectively
The influence of oestrogen and testosterone replacement on stroke risk has been examined, as well as mechanisms by which oestrogen may protect from post-stroke damage. However, whether testosterone levels in the early time period after haemorrhagic stroke influence long-term mortality has not
OBJECTIVE
To determine whether male sex steroids contribute to the depression in cell-mediated immunity following trauma-hemorrhage and resuscitation.
METHODS
Two weeks before the induction of soft-tissue trauma (2.5-cm midline laparotomy) and hemorrhagic shock (mean [+/-SEM] blood pressure, 35 +/-
The object of the study was to determine whether male and female sex steroids produce divergent effects on Th1 and Th2 cytokine release following trauma-haemorrhage. Recent studies indicate that androgens are responsible for the depressed splenocyte Th1 cytokine release in males following
