A MICROSCOPIC STUDY OF CHLORPROMAZINE (LARGACTIL) TREATED AXOLOTL LARVAE.
In previous publications (Eyal-Giladi & Eyal, 1962; Eyal & Eyal-Giladi, 1963) some of the macroscopic effects produced by chlorpromazine (CPZ) on the development and growth rate of Axolotl embryos have been reported. They include different abnormalities (microcephaly, defects in eyes, gills and pigmentation) depending on the CPZ concentration used and the length of the immersion period. In addition, larvae subjected to high CPZ concentrations and longer time of treatment proved, at the time of fixation, to be smaller than the controls, whereas larvae treated by low CPZ concentrations tended to grow bigger than the controls.

The teratogenic effect and the influence on growth being established, a microscopic examination of the same material was undertaken.

Three experimental series were run, each starting with a different initial developmental stage (Harrison's stages 10–11, 15–16 and 29–30 respectively). Specia's (Paris) CPZ chlorhydrate powder was dissolved in sterile tap water.
Hefzibah Eyal-Giladi (1925-2017): over fifty years of embryological research in Israel.
Hefzibah Eyal-Giladi was a creative and innovative pioneering scientist in the creation of the field of early chick embryo development. She had a sharp thinking and enthusiastic attitude, which enabled her to make a deep impression that was highly valued by the general scientific community. Notably, she was a highly successful female researcher in an era which was dominated by male scientists. Her unique personality and keen intellect enabled her to break these borders in a most successful manner. The experiments conducted by her personally, her students and her collaborators served to provide the basic knowledge and paradigms for future scientists in the field, also paving the way for discoveries in other vertebrate model systems. The experimental embryology assays she performed were "old school", examining embryos and explants at a precise morphological level of tissue interactions. In recent years, most of the experimentation in embryology has shifted to molecular and genetic levels. However, the results obtained with these technologically advanced research tools still re-confirm the fundamental findings obtained by Eyal-Giladi using "classic" experimental embryology techniques. Finally, Hefzibah Eyal-Giladi was an outstanding teacher and lecturer. For five decades, she trained and taught generations of undergraduate and graduate students in Israel, exposing them to the field of embryology and developmental biology in the most exciting and enthusiastic way.
On the fractionation of β-lactoglobulin and α-lactalbumin
Abstract Existing methods for the preparation of α-lactalbumin and β-lactoglobulin are examined critically. It is proposed that the most satisfactory method for the preparation of the whey protein fraction from bovine milk is (NH 4 ) 2 SO 4 fractionation. A number of new gentle procedures for the fractionation of the whey proteins are compared with some existing methods. The distribution of total protein at various stages is determined by total Kjeldahl nitrogen and the kind of protein by starch-gel electrophoresis. The effect of variables, such as pH, salt concentration and temperature on the separation of α-lactalbumin and serum albumin from β-lactoglobulin is studied. Differences in the behavior ( e.g. solubility) of genetic variants of β-lactoglobulin are noted. The solubility of each of the major whey proteins, under similar conditions to those used in the fractionation, is compared with its solubility in the whey protein mixture. The understanding gained of factors important in the fractionation is used in recommending new procedures for α-lactalbumin and β-lactoglobulin isolation.
