We have examined the transcriptional activities of the mouse oocyte genome during follicle growth in order to obtain information on the stages at which the synthesis of particular RNA species becomes important. The effects of gonadotrophins on these patterns of transcription have also been investigated. RNA synthesis in oocytes was measured at different stages of growth using a cytochemical application of the standard biochemical assay for DNA-dependent RNA polymerase. The presence of endogenous nucleolar and nucleoplasmic polymerases was detected by autoradiography and their relative activities were quantitated by grain counts. Both activities were relatively low in oocytes of the resting pool of small follicles but increased as growth commenced, reaching a peak as the oocytes approached maximum size. Thereafter RNA polymerase activities declined rapidly and were very low in the oocytes of large, antral follicles. Administration of PMSG to mice had no significant effect on the polymerases of oocytes of small follicles or during the early stages of follicles growth when compared with saline-treated controls. However, in oocytes which had attained maximum size, a statistically significant increase in nucleolar labelling was detected after PMSG treatment. The elevated levels of RNA polymerase activity were confined to oocytes within this growth compartment. These observations are discussed in relation to the way the production of gene transcripts is regulated during the growth of the oocyte, both with respect to the storage of informational molecules and the development of meiotic maturation competence.

Summary. A. Anatomo-pathological research on rats ingesting different doses of peanut oil or of low-erucic acid rapeseed oil (Primor rapeseed oil). 4. General ariatomy of the myocardium. The general anatomy of the myocardium (histiocytic infiltrations, fibrosis, loose connec- tive tissue, white spots) was studied on 4 rats from each lot. No dose or oil-effect was found. The length of the diet generally tended to influence the development of lesions.

The morphological maturation of Bergmann glia cells, which might play a particularly important role in the histogenesis of the cerebellar cortex, was studied in GolgiCox preparations and electron micrographs of the cerebellum of normal and undernourished young rats. An unexpected acceleration in the morphological development of Bergmann glia cells was observed in the undernourished animals during the early postnatal period.

This 2 x 2 factorial experiment (table 1) was carried out in the autumn on 22 Limousine ewes during pregnancy and lactation. The animals bore or were suckling twins. The experimental treatments included 2 levels of energy intake during 7 weeks prepartum (high : H ; low : B) and 2 states of body reserves at 8 weeks prepartum (fat : G ; lean : M). Jugular blood samples were taken from ewes at 34, 20 and 6 days prepartum, and from lambs at lambing and at 6 hrs., 24 hrs., 12 days and 24 days after lambing. Blood glucose, urea and free amino acids and plasma insulin were recorded. Reducing dietary energy supply did not change lamb birth weight in autumn (fig. 1 A). It contrasted with a large diminution in the spring (Grizard et al., 1979a, b). There was a decrease of glucose and of some non-essential free amino acids (alanine, glutamate, proline, citrulline) in the blood of the ewes. Most of the non-essential free amino acids decreased during the first day of life in the blood of lambs (fig. 2A). Reducing body reserves resulted in an increase of glucose and glutamine but in a decrease of some other free amino acids (glutamate, ornithine, histidine) in the blood of ewes (fig. 1 B). It increased daily weight gain during the first 3 weeks of life in lambs (fig. 2B). At the beginning of life, plasma insulin in lambs seemed to be related to birthweight and to blood glucose in the mothers.
