We have investigated the ability of murine monoclonal antibodies (MoAb) to lyse human leukemic cells in vitro using human serum as a source of complement (C'). The human C'-fixing ability of five of seven MoAb is documented. Studies with two of these MoAb (BA-1 and BA-2) indicated that their human C'-fixing ability and subsequent lysis of leukemic cells was through activation of the classical p...

Raman scattering experiments from high-1; superconductors of the RBa2Cu307-~ type, with R Y, Pr, Nd, Eu, Gd, Dy, and Yb, are reported. Because of the great difBculty in obtaining single-phase samples, spectra from all starting compounds and other known phases of Y-Ba-Cu are presented. This systematic approach has allowed the identi6cation of the lines observed in Raman spectra of the supercondu...

In the title compound, [Ba(C(14)H(20)O(5))(2)][Co(NCS)(4)], the Ba(II) and Co(II) ions are situated on twofold rotational axes, so asymmetric unit contains half each of the complex cations and anions. The Co(II) ion is coordinated by four N atoms [Co-N 1.83 (2), 1.95 (3) Å] in a distorted tetra-hedral geometry. The Ba(II) ion is coordinated by ten O atoms [Ba-O 2.766 (19)-2.859 (19) Å] from two...

Complete (Ba-L) and truncated (Ba-S) forms of alpha-amylases from Bacillus subtilis X-23 were purified, and the amino- and carboxyl-terminal amino acid sequences of Ba-L and Ba-S were determined. The amino acid sequence deduced from the nucleotide sequence of the alpha-amylase gene indicated that Ba-S was produced from Ba-L by truncation of the 186 amino acid residues at the carboxyl-terminal r...

Human B-cell tumors have been established in athymic, BALB/c mice using the EBV-positive Burkitt lymphoma cell line Namalwa. One-hundred-one of 104 animals (97%) developed tumors 10-14 days following s.c. injection of a mixture of 20 x 10(6) Namalwa and 5 X 10(6) irradiated human fibrosarcoma (HT-1080) cells. Tumors developed at the site of injection and reached approximately 300 mm2 (product o...

R ECENTLY, synthetic angiotensin II has become available for study. Page, Helmer, Braun-Menendez, and co-workers have demonstrated that this compound represents the reaction product of renin on the ao-globulin hypertensinogen. Intensive pharmacological studies conducted by the Cleveland group' 4i 3 and the Swiss have verified these observations that synthetic angiotensin I I is identical with t...

The aim of this study was to develop a formulation to improve the oral absorption of baicalin (BA) by combining a phospholipid complex (PC) and self-emulsifying microemulsion drug delivery system (SMEDDS), termed BA-PC-SMEDDS. BA-PC was prepared by a solvent evaporation method and evaluated by complexation percentage (CP). The physicochemical properties of BA-PC were determined. The synergistic...
