The sudden onset of anuria in a 71-year-old man was found to be caused by the non-inflammatory (atherosclerotic) large abdominal aortic aneurysm compressing the bilateral ureters. A computed tomography scan demonstrated the bilateral extrinsic ureteral obstructions due to the large aneurysm of 13cm in diameter, left hydronephrosis and no thick layer of perianeurysmal fibrotic tissue. On the 9th day from the onset of anuria, an emergency operation was performed. There was no fibrotic adhesions around the aneurysm and mobilization of the aorta was easy. A straight Dacron prosthesis was inserted between the infrarenal aorta and the bifurcation of the abdominal aorta following resection of the aneurysm of the atherosclerotic origin. Soon after the operation, the patient had very good urinary output with adequate recovery of renal function. This case seems to be very uncommon, but very important in the surgical management of abdominal aortic aneurysm complicated by oliguria or anuria.

Histochemical patterns of lectin binding during development of the rat vomeronasal organ (VNO) were studied to determine whether glycoconjugates are differently expressed after birth. Three types of lectins, Dolichos biflorus agglutinin (DBA), wheat germ agglutinin (WGA), and Ulex europaeus agglutinin I (UEA-I), were studied histochemically in the rat VNO at various stages post-birth: postnatal days 1 and 7, the preweaning period (4 weeks after birth), and at sexual maturity (8 weeks after birth). The free border of the vomeronasal sensory epithelium was positive for both WGA and UEA-I in rats of all ages; whereas, VNO receptor cells and supporting cells were positive only for both WGA and UEA-I from 4 weeks after birth. DBA reactivity was detected in the free border but less so in receptor cells and supporting cells. WGA and UEA-I, but not DBA, showed similar patterns in various ages. In the Jacobson's gland, WGA, UEA-I and DBA were detected in some acini from 4 weeks after birth but not at postnatal days 1 or 7. Collectively, reactivity for three lectins, WGA, UEA-I and DBA, increased in receptor cells and gland acini during postnatal development, possibly contributing to the enhanced chemoreception in rats.
