Abstract
The mechanism of cell dissociation with trypsin and EDTA was examined. Cell dissociation was possible when trypsin and EDTA were given simultaneously, when trypsin was given after EDTA treatment, but not when trypsin was given before EDTA treatment.

Abstract
The fibrin-agar plate method was used to estimate fibrinolytic activity from the luminal surfaces of aorta and vena cava with or without denudation of endothelium in rabbits. Diffuse endothelial denudation was accomplished by air-dry injury to the luminal surfaces for 24 hours prior to sacrifice. The segments individually obtained from the aorta and vena cava were immediately turned inside out in a cylindrical fashion and soaked in a vial containing plasminogen-rich solution. The vials were kept in a refrigerator at 4 degrees C for 4 hours. Five microliter of the solution was dropped on a fibrin-agar plate containing 0.08% fibrinogen (plasminogen free) and 1.4% agar in 0.01 M phosphate buffer with a pH of 7.4. A thrombin solution was then added to the plates, which were incubated for 18 hours at 37 degrees C in a moist chamber. The fibrinolytically digested areas revealed no comparative difference in fibrinolytic activity between the aorta and the vena cava either in the experimental or control group. However, a plasminogen activator was detected on the luminal surfaces of both the aorta and the vena cava with endothelial denudation as well as in normal controls. These results suggest that luminal fibrinolytic activity may be located not only in endothelial cells but possibly in other sources as well. Further examination of the interaction between the tissue activator and the inhibitor and determination of their localization are needed. Thrombogenesis may be an important factor in atherogenesis; in certain circumstances, detachment of the endothelial cells exposes underlying collagen fibrils and subsequently initiates the aggregation of platelets and cellular proliferation in the intima. There are, however, many unresolved questions concerning the precise mechanisms of development, resolution and organization of thrombi.

Abstract
The synthesis and the in vitro and in vivo antimicrobial activities of a series of 7-[2-(2-aminothiazol-4-yl)acetamido]cephalosporins (1) having varied 3-substituents, such as methyl, hydroxymethyl, acetoxymethyl, pyridiniomethyl and heterocyclicthiomethyls, are described. The derivatives having five membered heterocyclicthiomethyls exhibited strong inhibitory activities against Gram-negative organisms including some strains of Escherichia coli and Proteus morganii which are insensitive to cefazolin and cephaloridine. Pronounced activities were noted with 7-[2-(2-aminothiazol-4-yl)-acetamido]-3-[[[1-(2-dimethylaminoethyl)-1H-tetrazol-5-yl]thio]methyl]ceph-3-em-4-carboxylic acid (1y; SCE-963).

Abstract
New cephalosporins modified in the acyl part of 7-(3'-oxobutyrylamino)cephalosporins (1), which have been described in the preceding paper, were synthesized by thiolation at the 2'- or the 4'-position, or by transforming the 3'-oxo group into a 3'-imino group. The most active compound in vitro was 3-[[(1-methyl-1H-tetrazol-5-yl)thio]methyl]-7-(4-methylthio-3-oxobutyrylamino)ceph-3-em-4-carboxylic acid (7c), which showed superior in vitro activity against Gram-positive and Gram-negative bacteria compared to the parent cephalosporin (1b) with the same 3-substituent. The ED50 value for 7c, however, was essentially equal to that of 1b in mice infected with Escherichia coli O-111.

Abstract
The effect of various hormones on cytological and biochemical properties of cultured hepatic cells were investigated in order to obtain long-term survival of the hepatocytes with adult liver functions in primary culture. Insulin supplementation of the culture medium enhanced the attachemnt efficiency of cells in primary culture without affecting either maintenance of morphological characters of epithelial cells or retention of liver-specific functions in cultured cells. A combination of dexamethasone and insulin was apparently effective in stimulating the formation of a monolayer of polygonal cells with granular cytoplasm and in maintenance of liver-specific functions for relatively longer periods. Supplementation with either dexamethasone or hydrocortisone alone enhanced tyrosine aminotransferase activities in cultured cells for at least 4 days postinoculation. These steroid hormones also allowed growth of small epithelial cells with clear cytoplasm and maintenance of increased albumin production for 8 days after inoculation. The roles of these hormones in the primary culture of isolated hepatic cells are discussed in the present paper.
