Chemotherapy in bronchogenic carcinoma.

The effects of three different chemotherapeutic treatment regimens on the survival of one hundred inoperable lung cancer patients was studied in a randomized clinical trial. Of the patients 36 received cyclophosphamide as a single agent, 31 patients actinomycin D--vincristine combination and 33 patients cyclophosphamide--methotrexate--vincristine combination. Epidermoid carcinoma was the most sensitive to the actinomycin D--vincristine combination, whereas small cell anaplastic carcinoma responded to cyclophosphamide alone, and to the cyclophosphamide--methotrexate--vincristine combination. In spite of shrinkage of the tumour no differences were, however, observed in the survival times of the eifferent groups.

Experiences with the use of the 131I-hippuran test as an indicator in functional patency of ventriculocardiac shunts in hydrocephalic children.

In this paper a method is presented that provides information on the function of ventriculocardiac shunts in hydrocephalic children. There is good correlation between clinically and operatively demonstrated obstruction of the shunts as well as with clinically found free C.S.F. passage through the shunt. However, the greatest benefit is provided with the aid of the present method in cases with equivocal obstruction of the shunt where in our experience some operations of the shunt could be postponed or completely avoided in some cases. Because of its simplicity, safety, rapidity, and easy repeatability the method is recommended for routine ambulatory and hospital use.

Decrease of utero-placental blood flow during prostaglandin F2alpha induced abortion.

Pregnancy had been terminated in 6 normal midtrimester pregnant patients by the extraovular injection of 10 mg prostaglandin F2alpha (PGF2alpha). In these 6 Experimental and 3 Control patients utero-placental blood flow had been measured, by changes in the density of radioactive Indium, distributed over the uterine area, as a function of time. In comparison with Controls utero-placental blood flow decreased in the Experimental patients already at 5 minutes after PG-treatment, long before advanced cyclic IUP evolved. This finding substantiates the conclusion (1-3), based on experiments in animal "models', that decrease in utero-placental blood flow is an early step in the mechanism of PG action.
