Examination of the follicular maturation influencing effect of Clostilbegyt by endocrinous and electronic monitoring.

The follicle maturation influencing effect of Clostilbegyt (50 mg Clomiphene-citrat) has been examined in 30 women suffering from primary or secondary sterility. For monitoring follicular development a vaginal ultrasound scanner was used. The development of yellow body and its adequate function have been controlled with serum progesterone determination. In the first therapeutical cycle daily 1 tbl. Clostilbegyt was used from the 4th day of the menstruation in a five day period. In the next cycle daily 2 tbl. were administered similarly. If the therapy was unsuccessful, then 3 tbl. per day Clostilbegyt was used as treatment in the 3rd cycle. In the course of monitoring with vaginal ultrasound scanner successful ovulation induction has been proved in 80% of the Clostilbegyt treated cases (in 24 of 30 cases). During the examination period pregnancy occurred in 7 cases (29.2%). Vaginal ultrasound monitoring is recommended by the author for ovulation induction therapy.

[Significance of the determination of estrogen and progesterone receptors in trophoblast diseases].

Binding capacity (Bmax) and affinity (Kd) of cytoplasmatic estradiol and progesteron receptors were determined in trophoblastic tissue and in decidual endometrium by the authors. Results in normal and pathological endometrium and in mature placenta tissue were compared. Both estrogen and progesteron receptors were proved to exist in the decidual endometrium nearest to the molar tissue. Their binding parameters are similar to those in normal endometrium. No progesterone receptors were found in the molar tissue. Binding capacity of estrogens were found to be similar to that of the normal mature placenta. The lack of progesterone receptors might be an etiological factor in the pathogenesis of trophoblast diseases.

Release of prostacyclin (PGI2) from trophoblast in tissue culture: the effect of glucose concentration.

It is known that short term cell culture system offers a reliable and reproducible means for measuring placental PGI2 production in vitro, in which factors controlling its production and metabolism can be studied. The aim of the present investigation was to study the effect of glucose on generation of PGI2 by trophoblast obtained from early pregnancy in short term cell culture. Trophoblast was cultured using the method of Jogee et al and the concentration of 6-oxo-PGF1 alpha in culture supernatans was measured by a specific direct radioimmunoassay (New England Nuclear, USA). There was a significant decrease in 6-oxo-PGF1 alpha production by trophoblast cells when incubating with increased glucose concentrations (300 and 600 mg/dl) compared to controls (without glucose). These data show for the first time that high concentrations of glucose inhibit PGI2 production by cultured trophoblast cells obtained from early pregnancy. The implication of these findings for the mechanism of development of congenital anomalies in diabetic pregnant women is discussed.

Maternal perception, tocodynamometric findings and real-time ultrasound assessment of total fetal activity.

"Total" fetal motor activity was determined in 111 healthy patients between 25 weeks of pregnancy and term using two real-time ultrasound devices simultaneously. Furthermore tocographic findings and also maternal perception of fetal movements of the same patients were stored synchronously on magnetic tape. A comparison was drawn between these three methods, i.e. real-time ultrasonography, maternal perception and tocographic tracings ("spikes" indicating fetal movements). Of all fetal movements, as assessed by real-time ultrasonography, the mothers perceived a total of 38% whereas "spikes" in tocographic tracings corresponded with fetal motor activity (excluding "breathing") in only 25% of the cases (P less than 0.001). Also major statistically significant differences could be found between maternal perception of fetal body movements with or without fetal limb movements in 56% and routine- tocography in 37% (P less than 0.001). Also isolated limb movements were most often detected by mothers (23%) than were revealed by tocographic findings (14%; P less than 0.001). Maternal signals were truly positive in 74% compared to tocography in only 56% of the cases (P less than 0.001). It is concluded that maternal perception of fetal movements is a more reliable method of monitoring fetal motor activity than analysis of tocographic tracings.

[Lockjaw in progressive myositis ossificans].

Frequency, symptomatology, course and therapy of myositis ossificans progressiva are described by means of literature references and personal observation in a patient. The patient was born in 1935 and the disease manifested itself for the first time in 1956 in the right sternocleidomastoid muscle. Despite surgery total trismus could not be prevented and later-on muscles and connective tissue of other areas ossified, too.
