Procedures are described for the preparation and extraction of carrier-free S35, based on the Cl35 (n, p) S35 reaction. Potassium chloride, sodium chloride, and ferric chloride have been used as target materials. The S35 is found to appear in a chemical form which exchanges rapidly with sulphate ion. Separation of S35 from irradiated potassium or sodium chloride is effected by taking advantage of the insolubility of these salts in aqueous hydrochloric acid solutions. Approximately 99.8% of the salt can be removed while leaving 95% of the S35 in solution. Separation from irradiated ferric chloride is effected by solvent extraction of the ferric chloride from aqueous 6 to 8 M hydrochloric acid solutions. Less than 0.1% of the total solids is left unextracted. The yield of S35 approaches 100%.

Decidual Prolactin

Abstract. Human decidual tissue from uncomplicated term pregnancies was incubated in vitro using a cross-over design of incubation lasting for 72 h. The decidual tissue of each membrane was added sequentially to media with the osmolalities 252, 315 and 387 mmol/kg, and the different osmolalities were in 33 experiments induced by changing the concentration either of sodium chloride, potassium chloride, mannitol, sucrose, or choline chloride. At 387 mmol/kg all substances elicited a significant increase in Prl secretion compared with the 315 mmol/kg media (14–27%) or the 252 mmol/kg media (26–46%). When the sodium chloride, potassium chloride, sucrose, and choline chloride media at 387 mmol/kg were compared in another 7 experiments, potassium chloride increased Prl secretion more effectively than the others (10%, P < 0.05). The incubation cross-over design did not permit determination of the decidual Prl content after incubation in each of the various media, but in 28 experiments the mean decidual Prl content was 12.7 mIU per 100 mg dry tissue (range 4–30) before and 8.7 mIU per 100 mg dry tissue (1–17) after the experiments. The mean amount of Prl secreted during the successive incubations was 152.2 mIU per 100 mg dry tissue (19–672) which showed the secretion to be a result of continued Prl production. The effect of osmolality was independent of the basal production rate. These results indicate that the intracellular ionic concentrations, probably of potassium ion or of chloride ion, are of importance in the regulation of the synthesis and secretion of decidual Prl in vitro.

AbstractThe low-temperature synthesis of bricks prepared from high-siliceous clays by the method of plastic molding of blanks was used. For the preparation of brick blanks, binary and ternary mixtures of high-siliceous clays, black sand, and bottle glass cullet were used. Gray-black low-porosity and high-porosity ceramics was obtained by sintering under conditions of oxygen deficiency. It has been established that to initiate plastic in mixtures containing high-siliceous clay, it is necessary to add montmorillonite/bentonite additives, carry out low-temperature sintering, and introduce low-melting glass additives with a melting point ranging from 750 to 800 °C. The performed investigations have shown that the sintering of mixtures with a total content of iron oxide of about 5 wt% under reducing conditions at Tsint. = 800°C for 8 h leads to the formation of glass ceramics consisting of quartz, feldspars, and a phase. The main sources of the appearance of a dark color is the formation of [Fe3+O4]4- and [Fe3+O6]9- anions in the composition of the glass phase and feldspars. By changing the contents of clay, sand, and glass in sintering, it is possible to obtain two types of ceramic materials: (a) in the form of building bricks and (b) in the form of porous fillers.
