Abstract: Methods for administering beta-adrenergic inverse agonists with improved pharmacokinetic profiles for the treatment of pulmonary airway diseases are disclosed. The beta adrenergic inverse agonists are formulated in a controlled-release formulation comprising: (1) a beta-adrenergic inverse agonist in a therapeutically effective quantity; and (2) at least one agent that controls release of the beta-adrenergic inverse agonist resulting in a pharmacokinetic profile that minimizes acute detrimental reduction in airway function with the first dose and with each successive dose. This pharmacokinetic profile typically results in slow release of the drug into the bloodstream resulting in a large average Tmax>4 hours. The controlled-release formulation may consist of multilayered matrix or erosional tablets, gastric-retention tablets, osmotic pump oral formulations, multiparticulate capsules or tablets or dermal patch.

Abstract: A method for bulk cryopreservation of biological material includes the steps of providing a flexible container, such as a freezer bag, containing biological material that is treated with a cryoprotectant and freezing the biological material to below -100.degree. C. and preferably below -196.degree. C. for deep freeze long-term storage. In the preferred embodiment, the bag is placed in a holder that maintains the cross-sectional area of the bag essentially constant and small enough (e.g., about 5 mm width to facilitate uniform heat transfer to and from all regions the bag. This facilitates uniform nucleation of the biological material after supercooling which enables controlled and uniform slow cooling through from about -7.5.degree. C. to a temperature in the range of about -40.degree. C. to -80.degree. C., thereby maintaining the viability of the cells.

Abstract: Extracellular neuraminidase (NANAase) is produced by the microorganism Arthrobacter sialophilum sp. nov. The enzyme is induced from this microorganism by a variety of glycoproteins. The preferred enzyme inducer is a hot water extract of edible bird's nest which has been mildly acid-treated. The microorganisms, after aerobic growth in complete medium of relatively simple composition, are harvested, washed, salt-shocked, and induced in mineral salts solution which leads to facile enzyme induction. The produced NANAase is purified by ammonium sulfate fractionation, DEAE cellulose chromatography, gel filtration and ultrafiltration. The enzyme can further be readily crystallized from concentrated solutions. Disc gel electrophoresis at both acidic and basic pH's showed a major protein band. The predominant protein contained NANAase activity. The NANAase has an apparent molecular weight of 87,000 daltons. The purified enzyme has a pH optimum of 5-6, an apparent K.sub.m of 2.08 mg/ml for Collocalia mucoid and 3.3 .
