In this study, through the combined effort and collaboration of 8 engineering education departments, teaching-learning processes and models were reviewed, and printed and bound student manuals developed on 120 different tasks and subjects. Audio-visual supportive material, already in use in laboratories, was added to form a complete teaching-learning package. In addition to promoting the maximum use of the newly acquired equipment, this study will also contribute to the development of laboratory practice, the in-service training of technical high schools teachers and help in the development of their own instructional program.

Retrospective analysis of chromosomal abnormalities was performed on 75 couples who had recurrent spontaneous abortion. Karyotyping of their peripheral blood lymphocytes was made on 75 patients and 75 their husbands. The overall incidence of chromosomal aberrations was 22.7 %(17 in 75 couple). Number of chromosomal abnormalities in wives was twelve. Another chromosomal abnormalities were found in five husbands. All of them were balanced form and their phenotypes were normal. The incidence of translocations among total chromosomal abnormalities was 64.7 % (11/17). The incidence of reciprocal translocation(72.7 %) was higher than that of Robertsonian translocation (27.3 %). There were six other abnormalities including one case of inversion and five cases of polymorphisms. amniocentesis or chorionic villi sampling was performed during subsequent pregnancy to couples who had balanced chromosomal abnormalities. The karyotypes were classified as balanced translocation in seven cases, inversion in one case and normal karyotype in one case. This study suggests that prenatal diagnosis should be emphasized in couples in which one person is the carrier of a balanced chromosomal abnormality.

Torsion of the adnexa is a well-known gynecologic cause of an acute surgical abdomen. Delay in diagnosis, inability to distinguish strangulation from necrosis, and fear of embolus dislodgement have made adnexectomy the accepted method of management of adnexal torsion. This condition occurs most commonly in the reproductive years, yet methods to preserve viable ovarian tissue have not been routinely used or evaluated. Therefore, in order to ascertain if color Doppler sonography(CDS) can detect adnexal viability, ultrasonography with CDS of the ovarian pedicle was performed in 27 patients in whom torsion of the ovarian tumor was confirmed surgically. We were able to identify a twisted vascular pedicle of the ovarian tumor by ultrasonography in 24 of 27 patients(88% detectability). In 10 patients in which pedicle arterial and venous blood flow was observed, the pathology specimens revealed normal, or edema with congestion, or early hemorrhage, but in the 9 cases where only arterial blood flow was observed or where there was no blood flow at all, pathology revealed hemorrhagic necrosis in all cases. In 5 cases where there was arterial blood flow the tumor was managed conservatively, either by detorsion or cytectomy, after which there was no cases of embolism or tumor recurrence during follow up ultrasonography. Normal follicular development and ovulation was also observed in these patients. In conclusion, for young women who are of child-bearing age in whom torsion of benign adnexal tumors is suspected, CDS should be conducted to detect torsion of the tumor and ascertain whether pedicle venous blood flow is present or not. If such blood flow is detected, the adnexa is considered to be viable and detorsion or cystectomy may be performed, thus preserving the ovary.
