Estimation of the minimum chylomicron contribution to tissue DR within 4 h after 5.3 μmol DRA was administered to piglets on a VA-deficient diet

	Mean organ weight	DR on RBP/g tissue1	Maximum DR on RBP circulated to tissue2	DR measured in tissue	Minimum DR from chylomicra3
	g	ng
Adrenal glands	1.01	7.3	7.4	29.8	22.4
Kidney	38.8	7.3	280	1190	910
Lung	97.3	7.3	710	1870	1160
Spleen	12.5	7.3	91	441	350

¹DR on RBP/g tissue was estimate dusing the following equation: $\frac{{\sum }_{n=1-240min}\{\text{n}[0.00038\text{ng}\text{DR}/(\text{mL}\cdot min)]\times 66\text{mL}\text{plasma}\}}{100\text{g}\text{tissue}}$, where 284 ng DR = 1 nmol.

²Maximum DR on RBP = (organ weight × 7.3).

³Minimum DR from chylomicra = (DR measured in tissue − maximum DR on RBP).
