Bomfim,Kátia Michelle dos Anjos; Garcia,Carlos Alexandre Borges; Reis,Francisco Prado; Palmeira,José Arnaldo Vasconcelos; Scher,Ricardo; de Lucca Júnior,Waldecy; Aragão,José Adeval; Vasconcelos,Francis Lima; Albuquerque Júnior,Ricardo Luiz Cavalcanti; Feitosa,Vera Lúcia Corrêa.
Lead is one of the heavy metals most used in industry. Poisoning due to long-term lead exposure is known as saturnism, and is an occupational illness that has been known for many years. Lead is highly toxic and can compromise the structural and functional patterns of organs and systems. The aim of this study was to examine the lungs and kidneys of fetuses from female Wistar rats exposed to lead acetate. In this study, the lungs and kidneys of 20 fetuses from female rats that had previously been treated with lead acetate were dissected, fixed, embedded in paraffin and stained with hematoxylin and eosin. Macroscopic changes to the shape, color and consistency of organs from fetuses treated with this heavy metal were observed, in comparison with organs from...

Echobiometrics kidney and renal artery triplex doppler of canine fetuses Arq. Bras. Med. Vet. Zootec.
Feliciano,M.A.R.; Cardilli,D.J.; Nepomuceno,A.C.; Crivalero,R.M.; Silva,M.A.M.; Coutinho,L.N.; Oliveira,M.E.F.; Vicente,W.R.R..
The aim of this study was to assess the sogographic parameters and biometry of canine fetal kidneys using the B mode, and to determinate the vascular index of the fetal renal arteries using the Doppler Triplex. Twenty four Shi-tzu and Pug, weighting between 4 and 10kg, aging between 4 and 6 years old were evaluated. The B mode, the fetal renal echobiometry and regularity of the renal surface, echotexture and cortex:medular ratio were evaluated during the 5th, 6th, 7th and 8th weeks of pregnancy. At the same time point of the B mode evaluation, the Doppler Triplex was carried out to assess the sistolic peak velocity (SPV), end diastolic velocity (EDV), vascular resistive (RI) and pulsatility index (PI). B mode revealed no fetal renal abnormalities and...

The Great Auricular Nerve in Fetuses International Journal of Morphology
Pillay,Pathmavathie; Partab,Prawesh; Lazarus,Lelika; Satyapal,Kapil S.
The great auricular nerve (GAN) is the largest branch of the superficial cervical plexus that winds around the posterior border of the sternocleidomastoid muscle, accompanied by the external jugular vein. Forty fetuses (right side: 40/80; left: 40/80) with gestational ages between 15 to 28 weeks were microdissected to document the anatomy of the GAN. The results obtained were classified as: i) Incidence and morphometry: GAN was present in 100% of the fetal specimens with average length on the right and left sides recorded as 12.65 ± 2.14 mm and 12.55 ± 2.82 mm respectively. ii) Course: GAN was located parallel to the transverse cervical nerve and the external jugular vein. Duplicate external jugular veins were observed in 5% (4/80) with GAN located...
