Recent cases of 21 deliveries without professional attendants, either obstetrician or midwife, occurred in two local districts of Ibaraki prefecture were studied, with special references to nonprofessional attendants, outcome of birth and puerperium, and health status of babies. Furthermore, the reason why these deliveries were given by mothers.
Without professional attendants were investigated. Also, an associated factors such as past experience of births, parental age and other social environment were reported.

In vitro uptake of tritiated thymidine in slices of human breast tumor tissues was studied by autoradiographic technique. Labeling index was determined as number of labelled cells/ 100 cells. The examined cases were 29 normal breasts, one pregnant breast, 4 lactating breasts, 25 mastopathic breasts, 8 fibroadenomas, 6 giant fibroadenomas and 38 carcinomas.
In normal duct epithelum, the labeling indices varied widely from 0.1% to 9.0% and mean labeling index was 2.7%, whereas the labeling index of atrophic duct epithelium was appearently low. The labeling index of breast tissue in pregnancy was 7.4%, and this value was comparable to the highest value in normal breast tissues. The labeling index of breast tissue in lactation was relatively low. The labeling indices of normal breast tissues related to age showed the peak on the group of 30 to 39 years of age, therefore, that pattern seemed to be proportional to endocrine maturity.
The mean labeling index of mastopathic breast was somewhat lower than that of normal breast tissue. According to the histological patterns of mastopathy, the mean labeling index was 2.2% in blunt duct adenosis, 0.7% in duct papillomatosis, 0.6% in sclerosing adenosis and 0.1% in apocrine metaplasia, respectively.
The mean labeling index of fibroadenoma was 3.1% and the value was lower than that of carcinoma, but higher than that of normal breast tissue. The labeling index of epithelial cells in giant fibroadenoma was higher than that in normal breast. The labeling in stromal cells was also highly noted, unlikely in other breast tissues.
The labeling indices in breast carcinoma tissue were distributed as widely as those in normal breast tissues. The mean labeling index of carcinoma was higher than that of normal breast tissue. According to the histological pattern of carcinoma, the labeling index in papillotubular carcinoma was some what lower than those of the cases with other histological patterns. The labeling in breast carcinoma in early stage was lower than that of carcinoma in advanced stage on respects of tumor size and involved lymphnodes.

The structure of heterophile human red cell antigen of the lipopolysaccharide from 'smooth' (S) strains of Shigella dysenteriae (EW-1) has been investigated.
Glucose, galactose, rhamnose, N-acetylglucosamine and nine oligosaccharides were isolated from this lipopolysaccharide by mild acid hydrolysis. Hemagglutination reaction of anti-Shigella dysenteriae chicken serum with human group O red cells was inhibited by the isolated galactose and the oligosaccharides containing galactosyl unit as the non-reducing end-group.
On the basis of the isolated oligosaccharides, it is proposed that the determinant of human heterophile red cell antigen may have a following structure; (galactosyl-)β-galactosyl-glucosyl-rhamnosyl- (1-3 or 6)-N-acetylglucosamine.

A case of Dandy-Walker's syndrome associated with anomaly of dural sinus, a 19-month-old girl, was reported. She was admitted on 22, Oct. 1968 because of gait disturbance and rt.-ventriculoatrial shunt was performed for the obstructive hydrocephalus caused by a space taking lesion of the posterior fossa.
Suboccipital craniectomy was carried out on 9, Dec. 1968 to verify a cause of obstructive hydrocephalus such as subdural hematoma or cerebellar tumors. In the procedures abnormal suboccipital dural sinus was opened, she became shock state and died three days after the operation.
At autopsy the fourth ventricle was remarkably dilated and showed typical findings of Dandy-Walker's syndrome. Abnormal suboccipital dural sinus was thought either double transverse sinuses or dilated occipital sinus.
There are few literatures describing abnormal suboccipital dural sinuses and no report of the same suboccipital dural sinuses as our case.
