Abstract: The game uses a standard 52 card deck, and is played by a minimum of an action player, a banker and a dealer. The dealer, deals the playing pieces, but does not act as the banker. The action player and banker place their wagers before the cards are dealt. The dealer deals 4 cards, each to the player and to the banker. The player, but not the banker, looks at his cards and arranges them in a front hand and a back hand and in any order desired. The front hand is to be played first. The banker's cards are turned over and placed in respective front and back hands. The two front hands are compared to show a win, lose or draw, using the rules of the game of Blackjack. If the action player wins, the banker satisfies the extent of the action player's wager, and that round of play terminates, and the remaining players lose their right to play in that round. Otherwise, play proceeds to the next player. If the action player loses, the amount of his wager is given to the banker.

Abstract: A radioimmunoassay for pyridostigmine in biological fluids. The method disclosed can detect 250 pg of pyridostigmine per ml of biological fluid using 0.1 ml of biological fluid. The antibody used in this method is raised from an antigen produced by diazotizing para-aminobenzoic acid and reacting the diazotized material with pyridostigmine to form a pyridostigmine-hapten solution, which is then reacted with bovine serum albumen. The antibody used in the disclosed method has a cross-reactivity with the major metabolites of pyridostigmine of less than 2%.

Abstract: A radioimmunoassay for physostigmine in biological fluids. The method disclosed can detect 100 pg of physostigmine per ml of biological fluid using 0.1 ml of biological fluid. The antibody used in this method can be raised from an antigen produced by either or two methods--diazotizing para-aminobenzoic acid and reacting the diazotized material with physostigmine to form a physostigmine-hapten solution, which is then reacted with bovine serum albumin or by using a Mannich reaction to directly conjugate physostigmine to bovine serum albumin. The antibody used in the disclosed method has a cross-reactivity with the major metabolites of physostigmine of less than 1%.
