Aberrant arterial supply to uterine fibroids from branches of the superior mesenteric artery.

Two patients, aged 48 and 45 years, were treated for symptomatic uterine fibroids with not only embolization of both uterine but also both ovarian arteries. Note was made of other collateral arterial supply via branches of the superior mesenteric artery (SMA). The two identified SMA branches were embolized for the first patient, but no embolization was deemed necessary for the other patient.

Intracorporal injection of hSlo cDNA restores erectile capacity in STZ-diabetic F-344 rats in vivo.

The ability of gene transfer with the pore-forming subunit of the human maxi-K channel (hSlo) to ameliorate the decline in erectile capacity commensurate with 12-24 wk of streptozotocin (STZ)-diabetes was examined in 181 Fischer-344 rats. A 2-mo period of STZ-diabetes was induced before gene transfer, and erectile capacity was evaluated by measuring the intracavernous pressure response (ICP) to cavernous nerve (CN) stimulation (ranging from 0.5 to 10 mA).

The effect of ovariectomy and long-term estrogen replacement on bladder structure and function in the rat.

PURPOSE The use of estrogen replacement therapy for treating postmenopausal urinary incontinence is a controversial topic. We examined the behavioral, cystometric and histological changes that occur with long-term estrogen depletion and supplementation in rat bladders to determine the role of menopause in lower urinary tract dysfunction. MATERIALS AND METHODS A total of 40 female Sprague-Dawley rats were placed into 1 of 3 groups, including bilateral ovariectomy, bilateral ovariectomy plus estrogen replacement and control.

Bladder injection of "naked" hSlo/pcDNA3 ameliorates detrusor hyperactivity in obstructed rats in vivo.

The goal of these studies was to examine the potential utility of bladder instilled K+ channel gene therapy with hSlo cDNA (i.e., the maxi-K channel) to ameliorate bladder overactivity in a rat model of partial urinary outlet obstruction.
