Abstract
Total cellular calcium levels do not change when 3T3-4a cells stop proliferating due to serum depletion, or when serum-arrested quiescent cells are incubated for up to 44 hours in calcium-deficient medium (approximately 10 micrometer Ca++). Upon stimulation with dialyzed serum cells enter S and progress through at least one cycle even at extremely low calcium levels in the culture medium (greater than or equal to 10 micrometer). Cells divide until a final cell density is attained which is proportional to the calcium concentration in the medium and cells reversibly arrest in G1. Cells which arrested in G1 in medium containing less than or equal to 26 micrometer Ca++ in the presence of excess serum can be stimulated to enter S in response to added calcium after a prereplicative phase of 14 to 16 hours. Serum does not affect 45Ca-uptake in these cells. Benzo[a]pyrene transformed 3T3 (BP3T3) cells have a 100--200 times lower Ca++-requirement than 3T3 cells but arrest in G1 at low Ca++ levels. In contrast, SV40-virus transformed 3T3 (SV3T3) cells that grow without restriction in monolayer cultures have even lower Ca++-requirements for growth than BP3T3 cells and have no Ca++-sensitive restriction point. Therefore, 3T3 and BP3T3 cells have retained the capacity to sense intracellular Ca++-pool sizes and to arrest in G1 at subthreshold cellular Ca++-levels.

Abstract
Three low molecular weight proteins: β-thromboglobulin (βTG), low affinity plalelet factor 4 (LA-FF4) and platelet basic protein (PBP) have been purified from the material secreted by human platelets stimulated by lonophore A231S7. The preparative steps included heating at 100°C for 5 min, isoelectric focusing (pH gradient 3.5-10.9 in sucrose) and affinity chromatography on hepar in-agarose (elution with 0.4-0.5M NaCl). BTG, LA-PF4 and PBP showed complete immunological identity using anti-LA-PFi, antibody. Their respective isoelectric points were at pH 7.0, 8.0 and 10.9. Purity was confirmed by NH2 terminal amino acid analysis (βTG; gly; U1-PF4 asp; PBP: gly) and electrophoresis. At the NH2 terminal end LA-PF4, had four additional amino acids (Asn-Leu-Ala-Lys) while residues 5-21 of LA-PF4 and 1-16 of βTG were identical. As determined by Isoelectric focusing and specific radioimmunoassay the proportions of βTG, LA-PF4 and PBP released from platelets were 70%, 14% and 16%, respectively. Evidence is presented that LA-PF4 is a nrotein originally secreted by human platelets and converted to STG by a heat labile protease associated with the platelets. The three proteins Initiated DMA-synthesis in serum-arrested Swiss 3T3 cells in 0.4% serum. Activity of PBP was observed below 1 ng/ml and saturated at 50 ng/ml. LA-PP4 and βTG were 10 or 40 fold less active, respectively.

Abstract
Various hormonal and non-hormonal agents were tested for their ability to induce ornithine decarboxylase (EC 4.1.1.17) in primary cultures of fetal rat liver cells that retain many of the differentiated functions of hepatocytes. The only agents to induce ornithine decarboxylase in this cell type were fetal calf serum, prostaglandin E1 and cyclic AMP derivatives. Also, the amino acid arginine would induce ornithine decarboxylase in this cell type following arginine starvation for 24 h. These observations are in contrast to the wide range of hormones, e.g. insulin, hydrocortisone, glucagon and growth hormone, than can induce ornithine decarboxylase in vivo in the adult rat liver but which are all without effect on fetal rat liver cells.

Abstract
Growth stimulation of either fetal rat liver cells or rat embryo fibroblasts in culture results in considerable increases in intracellular polyamine levels as cells proceed through the cell cycle. Treatment of such cell cultures with appropriate levels of two inhibitors of polyamine synthesis, namely alpha-hydrazino ornithine and methylglyoxal bis (guanylhydrazone), can essentially completely block these increases in cellular polyamine content. Under such conditions, where the elevation in intracellular polyamine content is prevented, cell cultures are nevertheless able to initiate DNA synthesis and subsequently synthesize DNA at rates comparable to untreated control cultures that have been growth-stimulated. These two cell types therefore contain sufficient polyamines when in a resting state (G1) to enable them to enter from G1 into S phase and traverse S phase at normal rates in the absense of further polyamine synthesis. The recruitment of cells into the first cell cycle, through serum stimulation of growth, therefore appears not to be mediated or regulated by the increases in intracellular levels of polyamines that occurs under these conditions. Conversely, the arrest of growth of these cell types resulting from serum deprivation is not mediated by a limitation of intracellular polyamine content.

Abstract
The serum-induced transition of 3T3 fibroblasts from resting to growing state is characterized by a marked increase in cellular ATP content, the maximal level of which is reached at the onset of DNA replication. This increase in cellular ATP during the G 1 period of the cell cycle is correlated with about 3-fold stimulation of transcription of rRNA measured in permeabilized cell in vitro. Addition of hypoxanthine to serum-depleted quiescent 3T3 cells gives rise to an increase in both the ATP pool and the rate of rRNA synthesis. The expansion of cellular ATP pools after growth induction by serum seems to be a prerequisite for initiation of DNA synthesis since inhibition of purine de novo biosynthesis by azaserine inhibits both ATP pool expansion and DNA replication. This effect of azaserine can be abolished by addition of hypoxanthine to the culture medium. It is concluded that (a) the increase of the rate of rRNA synthesis in 3T3 cells in response to growth factors or serum is controlled by the cellular purine nucleoside triphosphate concentration and (b) an increased ATP level is necessary for initiation of DNA synthesis but is not sufficient to trigger the events that lead to DNA replication.

Abstract
The effects of the newly synthesized neuromuscular blocking agent, chandonium iodide (17a-methyl-3beta-pyrrolidino-17a-aza-D-homo-5-androstene dimethiodide) have been investigated on guinea-pig isolated ileum and vas deferens preparations. On the ileum, chandonium (0-1-10-0 mug ml(-1); 1-6 X 10(-7) M-1-6 X 10(-5) M) had weak muscarinic receptor blocking action (pA2 is 5-7), but no antihistamine properties at the concentration tested. No evidence for anticholinesterase actions was found. On the vas deferens, chandonium (10-50 mug ml(-1); 1-6-8-1 X 10(-5) M) potentiated responses to exogenous noradrenaline; responses to electrical stimulation were potentiated only in the presence of 50 mug ml(-1) chandonium. No adrenoceptor or adrenergic neuron blockade was found. The results provide evidence that chandonium acts selectively at acetylcholine receptors and that it is more active as a nicotinic receptor antagonist than as a muscarinic receptor antagonist.

Abstract
The specific demand of sodium hydroxide is determined for the dissolution of sunflower seed globulin, casein and a mixture of them to equal parts. In low protein-containing solutions it depends for sunflower seed globulin very much on the sodium chloride concentration. From sunflower seed globulin, casein and a mixture of them to equal parts are prepared with sodium hydroxide high protein-containing alkaline solutions. Sunflower seed globulin forms temporally a gel phase. After this phase the solution of sunflower seed globulin shows like casein and a mixture of sunflower seed globulin/casein (I:I) pseudoplastic flow. The flow curves of the pseudoplastic solutions are described mathematically with the OSWALDian power statement. By alkaline solutions of casein and sunflower seed globulin/casein (I:I) the flow exponent n is distributed statistically about 0.9, by solutions of sunflower seed globulin a distribution exists about the mean values n = 0.85 and n = 0.50. lg k depends in all protein solutions on the concentration of protein, sodium chloride, sodium hydroxide and on the temperature and time. For all protein solutions exists a linear relation between the logarithm of viscosity and the reciprocal temperature for lg k and I/T, which is derived normally for NEWTONian flow behaviour. In a suitable scope of spinning for all protein solutions are carried out complete factorial experiment, which guide to regression equations of lg k; in the case of sunflower seed globulin are calculated also a regression equation of the flow exponent n. Going out from the parameters of the spinning process the properties of the spun sunflower seed globulin/casein (I:I) fibers are described.

Abstract
An extracellular bacteriocidal substance is produced by a serotype c strain of Streptococcus mutans in liquid meduim during the stationary phase of growth. The lethal effect of the substance was demonstrated by the decrease in viable counts of a standardized suspension of group A streptococci in broth. No lysis of affected cells was observed and no changes in appearance of these cells was seen in electron micrographs. The material was effective against certain strains of immmunological groups A, C, D, G, H, L, and O streptococci. It was inactive against strains of S. mutans belonging to the a, b, c, and d serotypes, Bacillus subtilis, Staphylococcus aureus, Pseudomonas aeruginosa, and Escherichia coli. The factor was purified 273-fold from the culture fluid by column chromatography. It was sensitive to trysin and Pronase and resistant to catalase. It possessed a molecular weight of more than 20,000 and was not dialyzable. The properties of this substance indicate that it is a bacteriocin. Group A streptococci, which had been treated with antiserum specific for the cell wall group and type antigens, were susceptible to the bacteriocin. Streptococcal strains resistant to the lethal action of the bacteriocin adsorbed the bacteriocin from the solutions, as did the sensitive cells. The bacteriocin was not adsorbed at 0 C.

Abstract
1. The actions of the new skeletal muscle relaxant chandonium (HS310) on the cardiovascular, respiratory and skeletal muscle systems of the cat under chloralose anaesthesia and on chick and rat isolated skeletal muscle preparations have been described. 2. In the cat chandonium exhibited a potent, competitive, non-depolarizing neuromuscular blocking action that was rapid in onset and of short duration. It possessed a selective atropine-like action at the cardiac vagus neuro-effector junction but little or no ganglion blocking activity. Neither adrenergic neurone noralpha-adrenoceptor blocking properties were evident. 3. Unlike tubocurarine, chandonium was without effect on the airways system of the anaesthetized cat. 4. Chandonium possessed weak anticholinesterase action. It is conceivable that this effect may contribute to its short duration of action. 5. The results from these studies suggest that chandonium may have possible clinical applications as a short-acting muscle relaxant.

Abstract
Primary fetal rat liver cells cultured in medium deficient in, but not free of, arginine in the presence of dialyzed fetal calf serum grow until the final cell density is attained and cells become quiescent in the Go phase of the cell cycle. When growing cells are transferred into arginine free medium, cells become reversibly arrested in Go. Fetal rat liver cells can be induced to synthesize DNA by addition of high levels of arginine to serum free medium. Low arginine levels in the culture medium do not induce cell growth unless serum is present. Serum stimulates arginine uptake in fetal rat liver cells suggesting that serum growth factor(s) act by increasing intracellular arginine levels high enough to initiate the growth cycle. Fractionation of fetal calf serum by gel filtration on G-200 Sephadex yields a partially purified arginine uptake stimulating activity which is eluted from the column in the same fractions that contain fetal rat liver cell growth promoting activity. Insulin induces DNA synthesis in quiescent fetal rat liver cells. Glucagon reverses the stimulatory effects of insulin. N-6,O-2-Dibutyryl adenosine 3:5-cyclic monophosphoric acid (But2c-AMP) (10-minus4 M) and theophilline (10-minus3 M) inhibit arginine uptake and the initiation of DNA synthesis by serum. The role of arginine in the control of DNA synthesis in fetal rat liver cells and the mechanism of action of serum growth factors are discussed.

Abstract
Abstract
The effects of a newly-synthesized series of mono and bisquaternary aza steroids have been investigated in the anaesthetized cat. All the compounds have been tested for neuromuscular blocking, ganglion blocking and vagolytic activity. The monoquaternary compounds of the series were weak neuromuscular blocking agents, their main action being to produce ganglion blockade and a fall in blood pressure. Both the bisquaternary compounds of the series primarily exhibited neuromuscular blocking activity of short duration and rapid onset. 4-Methyl-17 β-dimethylamino-4-aza-5α-androstane dimethiodide (HS-467) was approximately equipotent with tubocurarine as a neuromuscular blocking agent, whereas 17a-methyl-3β-pyrrolidino-17a-aza-D-homo-5-androstene dimethiodide (HS-310, chandonium iodide) was 4–5 times more active. Both compounds exhibited extremely weak ganglion blocking activity. Structure-activity relations are discussed, and it is concluded that in this series two quaternary heads are necessary for optimal neuromuscular blocking activity. The possibility that in the bisquaternary compounds interonium distance, or stereochemical conformation may be the main factor in determining specific neuromuscular blocking activity is discussed.

Abstract
Abstract
The effects of the newly-synthesized bisquaternary steroid 4,17a-dimethyl-4,17a-diaza-D-homo-5α-androstane dimethiodide (HS-342) have been investigated on the rat isolated phrenic nerve-hemidiaphragm, chick biventer cervicis and intact cat tibialis anterior muscle preparations, on the guinea-pig isolated ileum and on the rat isolated vas deferens preparations. The anticholinesterase activity of HS-342 was also measured. In the skeletal muscle preparations HS-342 exhibited properties of a post-junctionally active neuromuscular blocking agent of the non-depolarizing class. In the anaesthetized cat HS-342 exhibited approximately equal activity to that of tubocurarine, but its duration of action was about one-third of that of tubocurarine. HS-342 exhibited low anticholinesterase activity, low muscarinic blocking activity and apparently had no effect on the adrenergic neuroeffector junction studied.
