Research Abstract

Histological examination of the peripheral circulation of the ovary of 18
females of the one-humped camel revealed a series of blood vessels with special
structures. Throttle or occlusive artery was recorded in the ovarian zona vasculosa
and in the cortex, and it showed an intimal cushion-like thickening made
up of intimal bolsters that formed of smooth muscle fibres and glomus cells.
The smooth muscle cells of the tunica media and the tunica adventitia of
throttle artery pursued a circumferential pattern. Anastomosis arteriovenosa
included simple bridge-like anastomotic vessels between arteria and venae, and
glomus vessels of typical structure were demonstrated. Glomus organs were
recorded in the ovary and were comprised of the tortuous glomus vessels and
the related afferent and efferent vessels. Glomus cell complexes also were commonly
occur at the cortex ovarii that possessed an extremely convoluted course
with a hyperplastic wall and a narrow lumen. Atypical glomus vessels were
demonstrated within the ovarian zona vasculosa, and the wall of these vessels
was relatively thick and consisted of double tunica media with an intimal bolster.
Some vessels contained an intimal bolster device of exclusively glomus cell
structure (glomus bolster) with a tunica elastic interna demarcated it from the
glomus cell media. Some venae represented several layers of longitudinally
arranged smooth muscle fibres in the tunica media. Other venae showed wall
with variable thickness. Venae with double muscular tunica media were
recorded in the medulla. Some venae showed double internal elastic lamina.
Also, venae with thick adventitia contained dispersed smooth muscle fibres
were determined. Spirally oriented arteriole and venule were demonstrated
within the cortex and medulla ovarii. Gestation sclerosis was demonstrated in
ovarian zona vasculosa of pregnant females.
