Estimation of gestosis of pregnancy (EPH-gestosis), relationship between fetal development and gestosis index.

Gestosis index score at delivery was compared with factors reflecting the fetal development in a series of 95 patients with EPH-gestosis collected in Okayama University Medical School in 1975-1979. The prediction of small for date (SFD) was performed by means of multivariate analysis of 10 variables, i.e. gestosis index, maternal body weight, height, uterine fundal length, abdominal circumference, maternal age at delivery and urinary estriol within one week prior to delivery. The result was that gestosis index was as useful as uterine fundal length in predicting SFD. The more gestosis index score increased, the more markedly the fetal development ws disturbed. Especially in the cases with scoring above 4 and in those with hypertension and proteinuria, the incidence of SFD increased obviously. No correlation between gestosis index and neonatal asphyxia was noticed. From the growth pattern of uterine fundal length and BPD, intrauterine growth retardation (IUGR) in pregnancy with EPH-gestosis occurred mainly within the third trimester of pregnancy. The functional development of the fetus with EPH-gestosis was evaluated with the use of urinary estriol level and fetal heart rate (FHR) monitoring. In the cases with EPH-gestosis scoring above 4, extreme disturbance of functional development of the fetus was observed.

Isolation and characterization of cyanogen bromide fragments of the A and B chains of the antitumor toxin ricin D.

Both the A and B chains of ricin D consist of four CNBr fragments. These fragments have been isolated from the separated chains of S-carboxymethylated ricin D obtained from the small bean variety of Ricinus communis. The peptides have been characterized by molecular weight, amino acid composition and amino terminal sequence. A unique order of the peptides is evident for each chain. These sequence data are compared with those obtained for ricin D isolated from the large bean variety.

Purification and physicochemical properties of ricins and agglutinins from Ricinus communis.

Two toxin ricins and two agglutinins have been purified from the seeds of Ricinus communis by an improved procedure based on ion-exchange chromatography and gel filtration. One of the two purified ricins binds to Sepharose 4B while the other does not. The physicochemical properties of the four Ricinus lectins are presented and the possible relationships of these Ricinus lectins to those previously described are discussed.

Revision and validation of the TWWA Scales.

A 40 true-false item questionnaire was finalized by revising and validating the original TWWA scales reported by Lin and Dickinson. This newly developed questionnaire consists of two scales measuring the degree of chemical abuse and the level of community functioning. Each scale has an internal consistency of .88, and all significantly discriminate three criterion groups: former addicts, their correspondents, and addiction workers. Demographic characteristics of the TWWA scales are also provided.

Fetal activity determination and neosynephrine test for evaluation of fetal well-being in high risk pregnancies.

At the special outpatient clinic for high risk pregnancies, a total of 197 patients were evaluated with fetal activity acceleration determination (FAD) as a non stress test. FAD was done on 197 patients, of these there were 8 fetal distress (4.7%) and 3 low Apgar scores (1 minute Apgar score less than 6) (1.8%) of 169 positive FAD, on the other hand, 14 fetal distress (50%) and 10 low Apgar scores (35.7%) of 28 negative FAD. Neosynephrine Test was performed in 62 cases as a stress test and the correlation between these two tests was evaluated. In 51 instances FAD was positive and the simultaneous Neosynephrine Test was normal. In 2 cases of negative FAD with positive Neosynephrine Test, there were 2 fetal distress (100%) and 2 low Apgar scores (100%). All the two tests are reliable for fetal evaluation in high risk pregnancies, because FAD and Neosynephrine Test are less time consuming and have fewer contraindications. It is concluded that the combination of these two tests are the most useful screening methods for fetal evaluation in high risk pregnancies.

Isolation and characterization of a low-molecular weight seed protein from Ricinus communis.

A seed protein with an apparent molecular weight of 5000 has been isolated and purified from Ricinus communis. This protein has a very high content of glutamine and an unusual ultraviolet absorption spectrum. The amino-terminal sequence of 22 residues determined by automatic Edman degradation is: NH2-Pro-Ser-Gln-Gln-Gly-Cys-Cys-Gly-Gln-Ile-Gln-Glu-Gln-Gln-Asn-Leu-Arg-Gln-Cys-Gln-Glu-Tyr-.
