Purification and partial characterization of protein 35/7.7 a cytosol protein that is abundant in rapidly growing hepatomas.

Protein 35/7.7 is an abundant cytosol protein of Morris hepatoma 3924A and Novikoff hepatoma which was not found in normal liver. Protein 35/7.7 was isolated from the cytosol of Novikoff hepatoma ascites cells by ammonium sulfate precipitation and DEAE-cellulose chromatography. It migrated as a single major spot on two-dimensional isoelectric focusing-SDS polyacrylamide gels. The N-terminal hexapeptide is Val-Asx-Pro-Thr-Val-Phe and its carboxyl-terminal amino acid is phenylalanine.

Isolation and characterization of a cytosol protein (64/7.2) present in large amounts in rapidly growing hepatomas.

Protein 64/7.2 (molecular weight/isoelectric point) is present in the cytosol of several hepatomas including the Novikoff hepatoma and Morris hepatomas 9618A, 7794A, and 3924A, but it is not present in liver or 18-hr regenerating liver. Quantitatively, its concentration was highest in Novikoff hepatoma (150 microgram/g tissue) and Morris hepatoma 3924A (550 microgram/g tissue), which are rapid-growing tumors, less in Morris hepatoma 7794A (72 microgram/g tissue), which is of intermediate growth rate, and least in the slow-growing Morris hepatoma 9618A (25 microgram/g tissue). Protein 64/7.2 was isolated from Novikoff hepatoma ascites cells in high purity as shown by its migration as a single band on one-dimensional acid-urea-polyacrylamide gels and a single spot on two-dimensional isoelectric focusing sodium dodecyl sulfate-polyacrylamide gels. Its amino acid composition has an acidic to basic amino acid ratio of 1.6. Its amino-terminal amino acid is lysine, and its carboxyl-terminal amino acid is glycine. Interestingly, the amino acid composition is strikingly similar to that of the phosphorylated Novikoff hepatoma chromatin Protein Cg', partially characterized in our laboratory.

Mothers' experiences of induction.

Mothers of a random sample of 2182 legitimate live births were interviewed about their experiences of pregnancy, labour, and delivery. Of these, 24% reported that their labours were induced, and data about this from a subsample of mothers tallied with information obtained through the doctors in charge in 88% of cases. All but 3% of the mothers who were induced perceived some medical reason for the induction. The proportion of inductions in the 24 study areas ranged from 6% to 39%. A relatively small proportion of labours in "teaching" hospitals, small hospitals with less than 100 beds, and GP maternity hospitals were induced, but a comparatively high proportion of private patients had an induction. There was no clear association between induction and the mother's age or parity. Despite being given more pain relief, those who were induced reported similar intensities of pain during the first and second stages of labour to those whose labour started spontaneously; they also reported that they had "bad pains" for a similar period. The period they had contractions was shorter for the induced than for those starting spontaneously, and the intensity of pain at delivery was rated somewhat less by those who were induced.There was no difference between induced babies and others in the proportion who were held by their mothers immediately after their birth. Two-fifths of the mothers who were induced would have liked more information about induction; and a similar proportion said they had not discussed induction with a doctor, midwife, or nurse during their pregnancy. Only 17% of the mothers who had an induction said they would prefer to be induced if they had another baby. This contrasts with 63% of those who had epidural analgesia who would opt for the same procedure next time, while 83% of those who had had a baby in hospital, and 91% of those having had a home birth, would want their next baby in the same type of place.
