Protease and basic amidase activity was found in the seminal plasma of the domestic turkey. Amidase activity, measured through use of N-alpha-benzoyl-DL-arginine-p-nitroanilide-HCL (BAPNA), was 23-28 times greater for turkey than for guinea fowl or chicken. Within the reproductive tract, seminal plasma from the vas deferens had much greater activity than testicular or epididymal fluids. Turkey seminal plasma enzyme (TSPE) purified by chromatography or isoelectric focusing showed three protein bands by PAGE, each resolving on SDS-PAGE into two subunits with molecular weights of approximately 28,000-32,000 and 38,000-44,000. One of the three proteins also contained a larger subunit (M(r) 76,000-81,000) thought to be transferrin. Turkey acrosin consisted of three subunits with molecular weights below 20,500. Acrosin, but not TSPE, was visualized in native gels with N-alpha-benzoyl-DL-arginine-beta-naphthylamide (BANA)/Fast Garnet stain. Michaelis constants (BAPNA) for TSPE, acrosin, and trypsin were 2.41 +/- 0.12 x 10(-4) M (n = 5), 4.96-6.03 x 10(-4) M (n = 2), and 6.76 +/- 0.95 x 10(-4) M (n = 6), respectively. TSPE, like acrosin and trypsin, was inhibited by benzamidine but not iodoacetamide. While all natural trypsin inhibitors tested inhibited acrosin, TSPE was not inhibited by ovomucoid from chicken or turkey egg white.

2-Chloro-deoxyadenosine (CdA) is a new adenosine-deaminase (ADA) resistant purine analogue with high specificity for lymphoid cells. It was shown that CdA is very effective in hairy cell leukemia (HCL), refractory chronic lymphocytic leukemia and cutaneous T-cell lymphoma leading to lasting remissions in the majority of patients with HCL. We report the successful treatment of five patients with HCL at different stages of their disease using CdA, who were either previously untreated or had received interferon, splenectomy and deoxycoformycin (dCF), an ADA-inhibitor with high therapeutic efficacy in HCL. After one 7-day course of treatment, all patients reached remission. CdA was well tolerated and, only mild side effects such as skin rash, headache, fever, nausea were observed. Aplasia was pronounced in all instances with a slow recovery. The type of histomorphological procedure in preparing and evaluating bone marrow biopsies is emphasized to detect minimal residual infiltration by hairy cells.
