摘要:
A hinge has a pair of leaves, one of which has a spaced pair of knuckles and the other has a central knuckle disposed therebetween. Disposed in the single knuckle are a pair of tubular bushing inserts received in opposite ends of its passage and having radial flanges disposed between the adjacent knuckles. The two knuckle hinge leaf is engaged with a pair of hinge pin elements extending inwardly from the opposite end of the leaf so as to prevent relative rotation therebetween, while the hinge pin elements extend into and are freely rotatable in the inserts. In the method of assembly, the bearing inserts are placed in the single knuckle leaf, and the two knuckle leaf is then aligned therewith and the hinge pin elements are inserted and engaged with the two knuckle leaf to prevent relative rotation therebetween.

Synthetic peptides corresponding to .alpha.-subunit of human glycoprotein hormone amino acid regions .alpha.31-45, .alpha.21-35, .alpha.26-46 and .alpha.81-92; were found to inhibit binding of 125.sub.I-bTSH to human thyroid. Peptides corresponding to regions .alpha.26-46 and .alpha.31-45 were also found to potently inhibit the stimulation of adenylate cyclase activity by bTSH in a TSH bioassay using FRTL-5 cells and block the action of thyroid stimulating immunoglobulin.

In various embodiments a fluid control device suitable for high pressure analytical instruments includes a housing having an interior surface with an end wall. The interior surface defines a chamber. A valve assembly disposed in the chamber controls the flow of fluid through the chamber. An end cap is disposed in the housing opposite the end wall to enclose the chamber. The end wall and end cap each have an opening to pass a fluid to the chamber or to remove a fluid from the chamber. The housing and end cap each has an abutment surface to receive the other abutment surface. At least one of the abutment surfaces has a plastic seal coating. A means of compression, such as a compression housing and compression sleeve, is included to engage the end cap to deform the plastic seal coating between the abutment surfaces and thereby seal the chamber.

Neurotensin analogs selective for neurotensin receptor subtype 2 are described. These include hexapeptides (NT(8-13)) and pentapeptides (NT(9-13)) having a D-3,1-naphthyl-alanine, D-3,2-naphthyl-alanine, an alanine derivative such as cyclohexylalanine, or 1,2,3,4-tetrahydroisoquinoline at position 11. Methods of treating pain by administering these neurotensin analogs are also described.
