RESUMEN
The strain 273 B, the type strain of a H serotype of Bacillus thuringiensis not yet characterized: B. thuringiensis subsp. cameroun, serotype H32, was isolated from soil samples collected in Cameroon. This strain produces cuboidal parasporal bodies composed of two major proteins of 53 kDa and 35 kDa. N-terminal sequences of the major proteins share no homology with published sequences. Only the 35 kDa protein is susceptible to digestion by trypsin. A complex array of 9 plasmids was revealed.

The transabdominal suprapubic study of the seminal vesicles was realised in 162 cases. Their relationship with the posterior bladder wall was examined. The normal distance between distal extremity of seminal vesicles-bladder wall measures 5 mm, and the distance between proximal extremity of seminal vesicles-bladder wall measures 7 mm. In case of benign hypertrophy, the seminal vesicles are pressed back and distance proximal extremity of seminal vesicles-bladder wall gets greater than 15 mm. In malignant hypertrophy of the posterior prostatic lobe, the position of the seminal vesicles does not change although the prostate has an increased volume.

The echographic rhythmic palpation (echosismography) is a new method which completes classical sonography. It studies the elastic behaviour of the tissues after their mechanical excitation which are analysed in the T.M. mode. When displayed in classical sonographic technique the lesion is located with calipers. Calipers allow the recognizing of the tumor level at any moment in time motion mode. Vibrations are then applied on the skin as near as possible to the lesion. A regular frequency of 1,5 impulsion per second at a constant pressure of 500 gr on 4 cm2 is used. The response of resonating tissues to vibratory excitation is recorded and characterized by the amplitude of the oscillations (sinusoïdal shape). Benign tumors always gave sinusoïdal type oscillations. Most of this kind of tumors were semi-liquid or solid. Malignant tumors gave typical flat curves in 84% cases. Some malignant tumors (16%) gave benign type sinusoïdal oscillations. They had a small size, less then 2 cm diameter. Some of them where to superficial so they had easily induced oscillations over the excitation level. Echosismography enables to improve the diagnosis when compared with classical sonography in about 20% of cases.

A new intragalactophoric biopsy fitting is described, which consists of a modified dilator serving as curette and a needle-curette for aspiration. The new fitting has been used successfully and without complications in 26 cases. It has the advantage of providing larger specimens for cytological examination of ductal tumours of the breast.
