This volume concludes the final report on the excavations of the Philistine sanctuary at Tell Qasile, the first part of which was published in Qedem 12 (1980). The major part of the volume deals with the rich stratified assemblages of pottery found in the various sanctuaries and surrounding structures at the site. The pottery is discussed in the text with accompanying photographs according to a typological classification developed especially for the site, and presented by stratified architectural units in the 48 pottery figures. Computerized registration of all the sherds found in stratified loci has enabled a comprehensive catalogue of pottery finds from each locus. A separate chapter reports the results of neutron activation analysis made on a sample of pottery from Tell Qasile. Other chapters describe the various bronze, iron, ivory, alabaster, and stone artifacts and the beads and scarabs found in the sanctuary. Studies of plant remains, animal bones, sediments, brick composition, and textile remains are presented in the appendixes. The concluding chapter summarizes the contribution of the excavations at Tell Qasile to the study of the Iron Age in general and the Philistine culture in particular.

“Relative Inhibitory Potential Of Urinary Macromolecular Fractions On Calcium Oxalate Precipitation.”. בתוך Urolithiasis Relat. Clin. Res., [Proc. Int. Symp.], 5Th, Pp. 839–842. Plenum.
Two distinct groups of macromol. inhibitors of Ca oxalate pptn. were found in the urine of healthy humans; one is \textgreater10,000 daltons, and the other is \textgreater500 but \textless1,000 daltons. The \textgreater10,000 dalton group was absent from the urine of stone formers. The data agrees with the hypothesis that several kinds of inhibitors are present in urine. [on SciFinder(R)]
The present paper reports alterations in osteogenesis recorded in mandibular condyles 3-18 days after the removal of marrow tissue from tibial bones. Computerized histomorphometric evaluation of undecalcified condyles revealed a considerable increase in the thickness of condylar cartilage, in particular, the zone of provisional calcification. Measurements of the subcartilaginous trabecular bone suggested an increase in the number of osteoblasts and in their activity. The systemic enhancement of osteogenesis may be initiated by circulating factors released at the affected limb during regeneration of the marrow.
The effects of solvent on the transition kinetics of polymorphic modifications of stearic acid were examd. in polar and nonpolar solns. Two typical polymorphs, B (low-temp. stable) and C (high-temp. stable), and the solvents (butanone, methanol, n-hexane, and decane) were studied. In all solns. the transitions from B to C and from C to B took place at temps. above and below 32°, at which the free energies of B and C have the same value, resp. The rates of the C → B transition were significantly dependent both on temp. and solvent. First, the transition rate was fastest between 22 and 26°. This was due to 2 conflicting factors; the free energy difference between B and C which decreases as the temp. approaches 32°, and the rates of dissoln. of C and growth of B which increase with temp.. Secondly, the solvent exclusively influenced the C → B transition; polar solvents, esp. methanol, caused a significantly more rapid transition than nonpolar solvents, the rates being relatively higher than those prediced by the soly. values. It was inferred that the different growth units (monomers in the polar solvents and dimers in the nonpolar ones) and the twisted lateral interface structures of the B polymorph would be responsible for the present solvent effect.

Human blood leucocytes generate large amounts of superoxide following stimulation by polyarginine, polyanetholesulphonate and mixtures of a variety of soluble agents. Generation of O2-. by the various "cocktails" of soluble ligands is markedly enhanced by cytochalasins A, B, C, D, E and F. The efficiency of cytochalasin A is, however, at least 50-fold greater than that of the other cytochalasins. Leucocytes that have been treated for a few minutes with the cytolytic agents saponin, digitonin and lysolecithin undergo lysis and lose their superoxide-producing capacities, when a variety of soluble ligands are employed to stimulate superoxide production. A partial reactivation of the superoxide-producing capacities of the leucocytes can be achieved by adding NADPH. However, as the concentration of the cytolytic agents increases, reactivation of the cytochrome C reduction is less inhibitable by SOD, suggesting that cell lysis releases reductases of cytochrome C not connected with the superoxide-producing system of the leucocytes. Both saponin and digitonin can totally replace polyarginine as ingredients of the "cocktail," suggesting that these agents may also function as "priming agents" for superoxide production which can, however, further be enhanced by the addition of mixtures of soluble agents. Thus, leucocytes which had been lysed by membrane-active agents can nevertheless produce superoxide if adequate amounts of NADPH are added.
The effect of primary emulsifier concn. (Span 80) in a system contg. Tween 80, mineral oil, and H2O on H2O transport due to an osmotic gradient was studied by a Coulter counter method. Diln. of W/O/W emulsions with dil. NaCl caused a decrease in multiple drop diam. due to loss of internal H2O. The primary mechanism appears to be micelle transport. [on SciFinder(R)]
Treatment with phosphates, thiazides and allopurinol was undertaken in 54 idiopathic calcium oxalate stone formers, 38 of whom were recurrent stone formers. The patients were followed up for 1 1/2 to 4 years (mean 2.6). During the same period at the pre-treatment stage the patients formed 80 stones, but during therapy only one stone was formed. A dynamic scheme of therapy was used. Each patient was tested before the start of drug treatment by the discriminant index (DI) method, which measures the overall inhibitory potential to calcium oxalate crystallisation. About 10 days after the start of treatment the DI was tested again. If the response was positive, therapy was continued; if not, the patient was given another drug. Adjustments were made as required. The stopping of stone formation correlated well with the DI prediction but less well with the hypocalciuric effect of the drugs.[on SciFinder (R)]
