[Clinico-echographic study of the ovulatory phase, spontaneous and induced, conceptional and non conceptional cycles].

We present the results obtained on 110 menstrual cycles of 87 patients; echography study of ovulation, immunologic LH determination, basal body register card and serial cervical mucus score, since -6 to 0 day. Echography study determined follicular diameter, endometrial bulk and the presence of liquid in the cul-de-sac. We considered only those patients in whom the disappearance of the follicle was observed 24 hours before; being this fact, the indicator of ovulation, related to all other variables. These patients presented spontaneous (47.3%), epimestrol (28.2%) or clomiphene induced (24.5%) cycles, and they turned out to be pregnant or not in that cycle, (34.6%, 25.8% and 37.0% respectively). It was 36 (32.7%) pregnant women in all the The three follicular diameter curves for pregnant cycles, were similar being the preovulatory follicular range 21.5 mm for spontaneous cycles, 18.9 mm for epimestrol induced cycles and 20.7 mm for clomiphene induced cycles. Conceptional range was from 15 to 22 mms, 15 to 22 mm, and 14 to 27 mms, respectively. We didn't observe free fluid in cul-de-sac in 5 pregnant cycles (13.9%). Most of positive LH, are about -2 and -1 (21% and 50%, respectively). There were one pregnant patient and 2 no pregnant patient with repetitive, negative LH. In 50% of patients who became pregnant, the Nadir was on -1 day. In spontaneous conceptional group, bad cervical score was not observed. The good cervical score period is longer on conceptional group than in those with epimestrol. On conceptional group, dissociation between best score day and the day of ovulations was not observed, fact that we observed in non-conceptional group.

[Treatment of tubal pregnancy by laparoscopy].

Three cases of ectopic pregnancy early diagnosticated are treated successfully with laparoscopic fulguration. Useful of this procedure is discussed and the needs of more experience is suggested.

Shift from polyploidizing to nonpolyploidizing growth in carcinogen-treated rat liver.

Liver growth patterns in normal and carcinogen-treated young Wistar Kyoto rats were analyzed in terms of absolute hepatocyte numbers and ploidy distributions, calculated from DNA measurements made by flow cytometry and microscope counts of binucleated cells. Polyploidizing growth was observed during normal liver development, dominated by progressive polyploidization and a decrease in the number of diploid cells. Nonpolyploidizing growth was seen during liver regeneration and after treatment with 2-acetylaminofluorene (AAF). This mode of growth was characterized by an increase in all mononucleated ploidy classes in the absence of net polyploidization (no increase in binucleated cells). Additional diploid proliferation was detected after initiation with diethylnitrosamine followed by promotion with AAF. This selectively expanding diploid hepatocyte population, which persisted after AAF withdrawal, could represent the AAF-promoted progeny of diethylnitrosamine-altered cells with constitutive nonpolyploidizing growth properties.

Uptake and degradation of asialo-orosomucoid in hepatocytes from carcinogen-treated rats.

The function of the asialo-glycoprotein receptor was studied in hepatocytes from carcinogen-treated rats. The cells were isolated at an early stage of carcinogenesis, when histochemically demonstrable enzyme-altered foci but no neoplastic nodules could be observed. The rate of uptake of a trace concentration of [125I]asialo-orosomucoid in hepatocytes from carcinogen-treated rats was significantly below the rate in normal hepatocytes. In contrast, the rate of degradation of endocytosed protein was not changed. The slower rate of uptake can be ascribed to an approximately 70% lower binding capacity in treated hepatocytes, whereas the association constant of the asialo-glycoprotein receptor is not changed. Hepatocytes from carcinogen-treated rats attached to a substratum of adsorbed asialofetuin at a slower rate than did normal cells, probably because of a lower density of asialofetuin receptors on the cell surface.
