Notizen: Abstract Electrophoretic variation of both the cytoplasmic and mitochondrial forms of the malic enzyme is described in Macaca nemestrina. Pedigree analysis of the observed phenotypes demonstrates that the two subcellular forms of the malic enzyme are genetically independent. The identity of the electrophoretic phenotypes in brain, heart muscle, liver, kidney, adrenal, and spleen from any given individual shows that each subcellular form is determined by the same genetic locus in a wide variety of tissues. After separation by ion exchange chromatography, the cytoplasmic and mitochondrial malic enzymes were shown to be distinct in their heat stability and K m for malate, but no significant differences were found among the variants of the cytoplasmic enzyme or among the variants of the mitochondrial enzyme. It is possible that the polymorphism of the mitochondrial malic enzyme is selectively neutral.

Notizen: Abstract Polymorphic variation of the human mitochondrial malic enzyme was detected in Caucasians and Negroes. The frequencies of the two alleles determining the three mitochondrial malic enzyme phenotypes were 0.69 and 0.31 in the Caucasian sample and 0.82 and 0.18 in the much smaller Negro sample. The distribution of phenotype frequencies among the 85 Caucasian males shows a significant deviation from Hardy-Weinberg equilibrium proportions. Two interconvertible forms of the cytoplasmic malic enzyme are described in human brain tissue, together with one variant in 132 Caucasian individuals.

Notizen: A treatment involving formaldehyde, a reducing agent, and a boron-containing compound of a wool shag carpet imparted to it a flame-retardancy effect that was effective after the seventh but not the eighth shampoo. This treatment also decreased the concentration of carbon monoxide and hydrocyanic acid generated in the products of combustion by at least a factor of 2. Analogous treatment of a wool flannel fabric produced a 15-22% sample area shrinkage and imparted a flame-retardancy effect that was still effective after a 2-hr cold water rinse.

Notizen: The surge in plasma luteinizing hormone (LH) in the proestrous hamster begins at 1430 (Turgeon and Greenwald, '72) and this is followed by a sharp increase in follicular and interstitially derived progesterone at 1500 (Norman and Greenwald, '71). The purpose of the present study was to relate various histologic events in the ovary of the preovulatory hamster to these physiological changes, dating from the LH increase between 1430 and 1500. The earliest maturational changes in the oocyte occurred at 1600 as the nuclear membrane began to disappear, correlating with an increase in the number of pycnotic nuclei in the surrounding cumulus cells and an abrupt reduction in mitotic activity in the membrana granulosa. It is possible that the latter event is related to increased progesterone secretion by the follicle at 1500. The most rapid increase in follicular diameter occurred between 2000 and 2200 - five to seven hours after the LH surge and was accompanied by a pronounced stromal edema especially of the medullary portion of the ovary. During this same time period, meiosis proceeded to the metaphase stage and the cumulus cells began to disperse to form the corona radiata. Of the eight hours required for the first meiotic division, four to six hours are spent in metaphase. The majority of animals (75%) ovulated by 0100 and all animals ovulated by 0200. Therefore, ovulation occurred 10 to 11 hours after the LH surge at 1500.
