    Notes: Abstract— Several major brain-specific proteins have been detected in cephalopods by electrophoretic analysis of the soluble proteins extracted from the optic lobes and other organs of octopus and by 2-dimensional fractionation of the soluble proteins from optic lobes and hepatopancreases of octopus and squid. One of the brain-specific proteins from octopus, identified as 0-1, has been purified by chromatography on DEAE-cellulose, Sephadex G-150, and DEAE-Sephadex. The protein appears to be pure on the basis of several physicochemical criteria. Amino acid analysis indicates a high content of glutamic and aspartic acids or their amides (or both) and the lack of tryptophan. A molecular weight of 17,000 has been calculated from sodium dodecyl sulphate-gel electrophoresis, gel filtration and ultracentrifugation analysis. The preparation of a specific rabbit antiserum against 0-1 has allowed its determination by agar immunodiffusion and complement fixation techniques. With the latter procedure it has been shown that the protein is absent outside the nervous system, is present in a concentration of several mg/g wet weight in octopus brain and is widely distributed within the octopus central and peripheral nervous system and in several molluscan species. It is also present in optic lobes of octopus at early stages of development.

    Notes: The serum cholesterol, trigylcerides and electrophoretic lipoprotein patterns of 35 postmenopausal women, who subsequently received sequential mestranol and norethisterone, were compared with those of 35 premenopausal women of the same age and weight. The postmenopausal women had a significantly higher level of serum cholesterol (p 〈0.01) than the premenopausal women, and a significant reduction (p 〈0.001) occurred in this group after two months of therapy. There was no significant difference in level of serum cholesterol between the premenopausal group and the postmenopausal group receiving sequential mestranol and norethisterone for two months. The serum triglycerides were not significantly higher in the postmenopausal group but there was a significant increase (p 〈0.001) after two months of therapy. The marked alteration in lipid levels at the menopause may in part account for the great increase in coronary artery disease in postmenopausal women but whether these changes are reversible by giving hormone therapy remains speculative.

    Notes: Summary An extracellular polysaccharide composed of glucose, fucose, arabinose and glucuronic acid in a molar proportion of 11:6:3:1 is a major end-product of photosynthesis by Palmella mucosa Kütz. The liberation of polysaccharide is related to the age of the culture. Glucose can substitute efficiently for CO2 as the source of carbon for polysaccharide synthesis. Nitrate-nitrogen from sodium, potassium and calcium salts can be used in the mineral salts medium with little differences in carbon metabolism of the alga. Ammonium nitrate produces an acidic medium which limits polysaccharide production. The incorporation of C14 into the polysaccharide from NaHC14O3 shows initially a trend toward intracellular synthesis. The C14 appears in the extracellular polysaccharide after prolonged exposure. Glucose-C14 is actively transformed to polysaccharide material which is an indication that glucose may play an important role in the synthesis of polysaccharide by Palmella mucosa Kütz.
