CLEARANCE, com. law. The name of a certificate given by the collector of a port, in which is stated the master or commander (naming him) of a ship or vessel named and described, bound for a port, named, and having on board goods described, has entered and cleared his ship or vessel according to law.
     2. The Act of Congress of 2d March, 1790, section 93, directs, that the master of any vessel bound to a foreign place, shall deliver to the collector of the [dis ot?] from which such vessel shall be about to depart, a manifest of all the cargo on board, and the value thereof, by him subscribed, and shall swear or affirm to the truth thereof; whereupon the collector shall grant a clearance for such vessel and her cargo; but without specifying the particulars thereof in such clearance, unless required by the master so to do. And if any vessel bound to any foreign place shall depart on her voyage to such foreign place, without delivering such a manifest and obtaining a clearance, the master shall forfeit and pay the sum of five hundred dollars for every such offence. Provided, anything to the contrary notwithstanding, the collectors and other officers of the customs shall pay due regard to the inspection laws of the states in which they respectively act, in such manner, that no vessel having on board goods liable to inspection, shall be cleared out, until the master or other person shall have produced such certificate, that all such goods have been duly inspected, as the laws of the respective states do or may require, to be produced to the collector or other officer of the customs. And provided, that receipts for the payment of all legal fees which shall have accrued on any vessel, shall, before any clearance is granted, be produced to the collector or other officer aforesaid.
     3. According to Boulay-Paty, Dr. Com. tome 2, p. 19, the clearance is imperiously demanded for the safety of the vessel; for if a vessel should be found without it at sea, it may be legally taken and brought into some port for adjudication, on a charge of piracy. Vide Ship's papers.

Inulin clearance, according to Tanner (2003), is the virtual volume of plasma which contains inulin eliminated by the kidneys in a certain period of time.
Mean (SD) inulin clearance tended to be higher with corticosteroids, 127 (25) ml, * [min.sup.-1] * (1.73 [m.sup.2).sup.-1] vs 118 (25) ml, * [min.sup.-1] * (1.73 [m.sup.2).sup.-1] P = 0.14.
The aim of this study was to design and validate an optimal sampling strategy for the inulin single-injection method that requires fewer samples while allowing reliable estimation of the inulin clearance in pediatric patients with renal disorders.
[4] Nonstandard abbreviations: [C.sub.In], inulin clearance; GFR, glomerular filtration rate; and [C.sub.Cr], creatinine clearance.
Among 184 children with renal disease and a mean age of 11.2 [+ or -] 4.5 years (range, 0.24-17.9 years), CysC correlated better (r = 0.88) to GFR measured by inulin clearance than did SCr (r = 0.72) (41).
It has been reported to be a better indicator of reduced GFR (estimated by inulin clearance) than serum Creatinine in the Creatinine-blind range (10), but not better than Cys-C (11).
As expected, we found an inverse correlation of homocysteine with the GFR measured as inulin clearance [r = -0.512 (95% confidence interval, -0.773 to -0.102); z-statistic, -2.4; P = 0.016].
Inulin clearance ([C.sub.In) is the usual gold standard for evaluating glomerular filtration rate (GFR), but technical difficulties and patient inconvenience prevent its widespread use (1).
(5) compared for the first time the diagnostic performance of cystatin C, [beta]-trace protein, [[beta].sub.2]-microglobulin, and creatinine in relation to inulin clearance. They noted that we reported a higher diagnostic accuracy of [beta]-trace protein in a study with 115 diabetic patients (4).
