polyarteritis nodosa is a multisystem necrotizing vasculitis of small and medium size muscular arteries in which involvement of the renal and viserat arteries is characteristic. the etiology is unknown but hepatitis b antigenemia is found in 30% of patients. drug exposures and hypersensitivity reactions are other possible causes. excellent therapeutic results have been reported in classic polya...

background and objective: the circle of willis (cow) supports adequate blood supply to the brain. the cardiovascular system, in the current study, is modeled using an equivalent electronic system focusing on the cow. method: in our previous study we used 42 compartments to model whole car- diovascular system. in the current study, nevertheless, we extended our model by using 63 compartments to ...

We present a patient with a failed radial coronary angioplasty as a result of bilateral brachioradial arteries, the radial arteries anomalously originating from the axillary arteries. We review the literature concerning abnormal origins of the radial artery and propose the left ulnar artery as optimal access of choice in cases with a right brachioradial artery of relatively small size in its pr...

(1) the secondary stage of freeze - drying, particularly the last day, is not important and i suggest the whole procedure is reduced to three days, the primary stage occupying two of these. (2) the mothod used obtains the satisfactory low level of residual moisture. resume (3) experiments on reconstitution with saline and distilled water show that distilled water is more satisfactory and i sugg...

Middle rectal artery is one of the important arteries supplying the rectum, along with the superior and inferior rectal arteries. Study of middle rectal artery was undertaken as it is important in surgeries of rectal carcinoma. .For the present study 40 pelvises were procured from the department of Anatomy of Dr. D. Y.

Background: To evaluate the effect of oxytocin on blood circulation of fetus and uterus by Doppler ultrasound. Materials and Methods: Forty six pregnant women were assigned to receive for indication of delivery intravenous oxytocin. Doppler velocitometry before and after administration of oxytocin for umbilical,middle cerebral artery and uterine artery were performed, and Pulsatility index (PI)...

Dextro-transposition of the great arteries (d-TGA) is the one most common cyanotic congenital heart disease in neonates. The discordant ventriculoarterial arrangement results in parallel circulation, it so is vital to understand the management. We report a rare interesting but critical case of 33-day-old boy who developed cyanosis and had transposition of great arteries combined with interrupte...

Briefly, based on the previous evidence and the results of the present study, it seems that infection with HTLV-1 by destruction of sub-layers of arteries, especially the intima layer, leads to disruption of the integrity of sub-layers of arteries and through various mechanisms, causing the sub-layer’s destruction, increasing the intima-media thickness, changing the lipid profile, and developme...

128 human hearts including 70 males and 58 females in all age groups were used for the present study. Coronary arteries dissected out from hearts. The luminal diameter was studied four major coronary arteries, namely, right artery (RCA), left (LCA), anterior descending (LAD) circumflex (LCX) both sexes. histological sections stained with H & E stain measured help of ocular micrometer. Among...
