(1) A segment of vas deferens was transplanted to the contralateral deferens with the intention of improving treatment for certain cases of infertility caused by obstruction.
(2) To minimise the risk of recanalisation (0.2%), 20 mm of vas deferens was resected.
(3) At a concentration of 10 microM, tetraamine 4 did not affect histamine and 5-hydroxytryptamine receptors of guinea pig ileum or alpha-adrenoreceptors of guinea pig atria whereas it inhibited postsynaptic alpha-adrenoreceptors of rat vas deferens with a -log K value of 5.23 and nicotinic receptors of frog rectus abdominis with an IC50 value of 0.23 microM.
(4) Emphasis is placed on techniques that prevent spontaneous recanalization of the ends of the vas deferens after vasectomy.
(5) After properly fixing the vas deferens with a ring clamp, the surgeon pierces the scrotal skin, vas sheath, and vas deferens in the midline with a curved dissecting clamp held at a 45 degree angle from horizontal.
(6) The acrosin inhibitors are localized in the mucosa cells of the cauda epididymis, the vas deferens, the seminal vesicles, the urethra and distinct glandular units of the prostate.
(7) It is thus concluded that the active core for the morphine like activity in the mouse vas deferens bioassay is the fragment 61-65 of beta-LPH.
(8) Microsurgical vasovasostomy for the reversal of elective bilateral segmental vasectomy (vasectomy, vas ligation) was done in 57 patients (61 operations) between May 1977 and March 1984.
(9) There was a significant positive correlation between the efflux of noradrenaline from platelets and vas deferens (r = 0.56, P less than 0.001).
(10) Supersensitivity to noradrenaline was produced by both of the stereoisomers in isolated vas deferens of guinea-pigs although there was no difference in the activity.
(11) At lesser intensities, VAS occasionally produced a small pressor response.
(12) Probably there is a continuity of this system throughout the entire vascular pole including (1) all granulated cells, (2) all lacis cells, (3) the mesangium cells and (4) the adjacent smooth muscle cells of the vas afferens and vas efferens.
(13) Pain scores (VAS) and responses to a pain questionnaire were similar for both groups; however, within Group B improvement in mean VAS scores at rest with time were more sustained.
(14) Various techniques have been described, but in this surgeon's opinion the simplest and best method is to remove a length of a vas such that it becomes a physical impossibility to approximate the cut ends.
(15) A 10-month-old boy with a crossed ectopic testis and a common vas deferens is presented.
(16) Within the epididymis, regions closest to the testis develop soluble ACE activity about 1 week before those nearest to the vas deferens.
(17) Pretreatment of the vas deferens with both HNBTG and 2'-deoxycoformycin eliminated the difference in inhibitory potency between adenosine and 2-chloroadenosine.
(18) We interpret these results to indicate that angiotensins stimulate PGE production by adrenergic nerves in the vas deferens and that released norepinephrine mediates a part of the PGE production in response to the angiotensins.
(19) The effects of the ATP affinity label periodate-oxidized ATP (ATP-2',3'-dialdehyde; P-ATP) on contractile responses of the guinea pig vas deferens to ATP was characterized and compared to the effects of the specific P2x-purinoceptor photoaffinity label antagonist, arylazido aminopropionyl ATP (ANAPP3).
(20) Knowledge of the mechanical properties of the vas deferens is important in order to understand the mechanical interaction between an intravasal device (IVD) and the vas deferens--a necessary step for successful long-term implantation.
