Abstract: An undergarment comprising a front panel composed of a first stitch pattern, a rear panel composed of a second stitch pattern, a waistband formed at the top of the front and rear panels, a leg band formed at the bottom of the front and rear panels and an interface. The interface is formed between the front and rear panels and generally extending at least partially between the waistband and the leg band on a side of the undergarment. The interface interleaves at least a portion of the front panel with at least a portion of the rear panel.

Abstract: A brassiere including a flexible underwire attached to the bottom edge of a first cup to define a cup contour. The underwire includes a straight first end, a second end, and a central, radiused portion. A first wing is made from an unstretched pattern and is attached to the first cup. The first wing has a first edge having a lower portion connected to and corresponding to a lower portion of the cup contour, and an upper portion that is recessed relative to an upper portion of the cup contour when the pattern is unstretched. When the brassiere is worn by the woman, the first wing is stretched, concentrating a pulling force through the upper portion of the first edge to the upper portion of the cup contour, reducing the capacity of the first cup and raising the breast received within the first cup to enhance the appearance of the breast within the first cup.

Abstract: An assay for Vitamin B.sub.12 deficiency by determining for a blood sample that essentially all of the Vitamin B.sub.12 is carried by a combination of TCI and TCIII and/or essentially no Vitamin B.sub.12 is carried by TCII. TCII may be conveniently separated from a combination of TCI and TCIII by precipitating TCII with silica. Vitamin B.sub.12 deficiency may be determined prior to the onset of anemia and/or nerve damage by determining a decrease in Vitamin B.sub.12 carried by TCII.

Abstract: Mitogen stimulated transformation of blood lymphocytes is effected with a whole blood sample of a quantity of no greater than 0.5 ml, and a mitogen to whole blood sample ratio which prevents agglutination of blood cells to thereby facilitate uniform uptake of reagents by the lymphocytes in subsequent testing. Lymphocyte transformation can be measured by use of a radioisotope, and the technique is particularly suitable for measuring vitamin deficiency by a dU or thymidine suppression test, or for determining lymphocytic malignancy. The use of a whole blood culture eliminates lymphocyte separation, and the use of micro quantities of blood extends clinical application to routine laboratories and pediatric patients.
