Normal sleep is associated to physiological nocturnal rises in Interleukin 1 beta (IL 1 beta) secretion. The 24 h pattern of IL 1 beta, beta-Endorphin (beta-EPH), ACTH and cortisol (F) production was evaluated in four male healthy volunteers. Two subjects were unable to sleep, due to the stress of the experiment; in these cases, no detectable plasma IL 1 beta secretion, both diurnal and nocturnal, was present, beta-EPH plasma levels were significantly higher (p < 0.01) than in the subjects who slept regularly and, in one case, increased F plasma levels were also reported. A strong negative correlation between IL 1 beta and beta-EPH plasma levels was present in all the cases. In conclusion, stress-induced sleep alterations might deeply affect both diurnal and nocturnal IL 1 beta plasma secretion, probably due to the hypothalamus-pituitary-adrenal axis (HPAA) activation, and beta-EPH might be the reliable marker of the stress-induced HPAA activation level.

The authors studied the incidence of individual aetiological factors which may cause intrauterine interruption of foetal development. The research concerned 26 pregnant women hospitalized in the Ward for Pregnancy Pathology of the Department of Gynaecology and Obstetrics over the period from 1986-1989. The majority of women with this manifested EPH gestosis: essential hypertension was observed in 3 patients (12%). Particular attention was paid to the final stage of delivery and to the Apgar Score. Discussion includes the results of other authors. In the conclusion the importance and significance of this problem are stressed--within the scope of perinatal medicine--in view of the high morbidity and mortality rates among infants.

Maternal lung edema due to the use of beta-mimetic tocolytic agents is a well-documented complication. The risk increases if several other factors are present: infectious diseases, the use of inhaled anesthetics, EPH gestosis, hydramnios, twin gestation and preexisting cardiovascular disease. The complications induced by beta-mimetic tocolytic agents can be reduced by remembering their side effects and contraindications and restricting fluid intake. During obstetric general anesthesia in patients undergoing tocolysis, the infusion of large amounts of saline, as is widely practised today, is strictly contraindicated.

At the Medical Central Department of Obstetrics and Gynecology in Sibenik over 1970-1991 period there were 26,116 deliveries (multiple births excluded), of which 254 (0.97%) occurred in grand multiparas (five and more deliveries). The authors have found that the number of grand multiparas decreased by 38.3% (P < 0.001) over the past eleven years. Control subjects were 7920 multiparas (two to four deliveries, 20-34 years of age, from the same period). In 84.3% of the cases grand multiparas were delivered of their fifth or sixth infant, and 68.5% were > or = 35 years of age. Spontaneous abortion occurred in 16.9%, and 14.2% had no antenatal visit. EPH gestosis (8.3%), glucose intolerance (9.9%), preterm delivery (8.3%) and meconium-stained amniotic fluid (15.0%) were more common in the grand multiparas, whereas cervical cerclage (5.4%) and 7-to-12-hour duration of labour (12.8%) were more common in the control group. No significant differences were found in weight gain, prolonged pregnancy, caesarean delivery, assisted breech and vacuum extraction between two groups. There was also no difference in the incidence of neonatal morbidity and congenital abnormalities between the grand multiparas and controls. Late fetal and early neonatal deaths in the grand multiparous and control group occurred in 1.18% and 1.57, respectively, resulting in a 2.75% overall perinatal death rate for both groups (P > 0.05). No case of maternal death or uterine rupture occurred in either group. The authors conclude that pregnancy and delivery in grand multiparas are at higher risk due to poorer antenatal care and advancing maternal age.(ABSTRACT TRUNCATED AT 250 WORDS)

This review is dealing with the roles of the immune system in the development and functions of the male and female reproductive systems. Further, it describes the topical views on the roles of immunopathologic events and mechanisms involved in the male and female infertility, recurrent abortions, endometriosis, EPH gestosis and disorders of fetal development. Particular attention is paid to the complicated immunological cross-talk and interplay between the mother and its offspring, including the active role played by the placenta and mainly the trophoblast tissue, in the course of gestation. In the light of the "immunotrophic theory", maternal immune responses to foreign fetal components, occurring in normal pregnancies, within the limits of "tolerated" or even beneficial levels, are described. Emphasis is given on the possible deregulation of materno-fetal immunological balance, leading to immunopathological events and putting in danger the overall reproductive capacity of the couple. The contemporary therapeutic--mainly immunological--approaches to the main reproductive failures are also mentioned.

To elucidate the relationship between the high concentration of taurine in platelets and platelet aggregation in patients with EPH gestosis (gestosis with edema, proteinuria and hypertension), platelet aggregation and the platelet release response (release of ATP and beta-thromboglobulin) were studied in the washed platelet suspension (PS) obtained from normal pregnant or non-pregnant women and EPH gestosis patients. Platelet aggregation and platelet release response were significantly lower in EPH gestosis patients than in normal pregnant and non-pregnant women. Platelet aggregation, platelet release response induced by ADP and collagen and the aggregation induced by A23187 were inhibited in taurine-loaded PS from non-pregnant women. These results suggest that the decrease of platelet aggregation in EPH gestosis patients was caused by high concentrations of taurine in platelets, which may inhibit the intracellular Ca2+ movement and platelet release response. Therefore, taurine appears to have a protective effect against the hyper-coagulative state in EPH gestosis.

Phenobarbital (PB) and certain structurally-related compounds induce a variety of hepatic drug-metabolizing enzymes in many strains of rats. Thus, following administration of PB (300, 500 ppm), barbital (BB, 1500 ppm) or 5-ethyl-5-phenylhydantoin (EPH, 500 ppm), CYP2B1-mediated benzyloxyresorufin O-dealkylase activity and epoxide hydrolase activity were profoundly induced in female DA and F344/NCr rats. In contrast, outbred female lean and obese Zucker rats showed markedly reduced CYP2B1 responses (less than 15% and less than 5% of those observed in the female DA or F344/NCr rat) to PB (doses less than or equal to 300 ppm), BB (1500 ppm) or EPH (500 ppm). In parallel studies, profound increases in RNA levels coding for CYP2B1, glutathione S-transferases Ya/Yc (alpha subclass), or epoxide hydrolase were detected in the female F344/NCr rat following treatment with PB (300 ppm), BB (1500 ppm) or EPH (500 ppm). In contrast, lean Zucker rats showed a strong response only to the highest dose of PB (500 ppm), implying that the diminished response in the Zucker rats may occur at some pretranslational level. Similar studies with lower doses of PB, EPH or BB in male lean Zucker rats showed a decreased response, relative to that in male F344/NCr rats. However, this insensitivity was not as profound as that observed in the female Zucker rats. In fact, the response to PB-type inducers in male or female Zucker rats is probably most clearly explained as a shift of the dose-response curve sharply to the right (decreased responsiveness, compared to F344/NCr or DA rats of the same sex). This decreased responsiveness of female lean Zucker rats to induction of CYP2B1, relative to that of F344/NCr rats, was also observed with the structurally-diverse PB-type inducers clonazepam, clotrimazole and 2-hexanone. In contrast, the female Zucker rat (obese or lean) displayed a pronounced response to induction of CYP1A-mediated ethoxyresorufin O-deethylase activity by beta-naphthoflavone, a prototype inducer of CYP1A1 and CYP1A2. The Zucker rat would thus appear to represent a potentially exploitable genetic model for examining the mechanism of enzyme induction by the myriad xenobiotics which induce a PB-type response.

The taurine concentration and uptake in platelets obtained from normal pregnant women and gestosis patients with edema, proteinuria and hypertension (EPH gestosis) were investigated. The taurine concentration in platelets showed a marked increase in severe EPH gestosis compared with normal pregnancy or mild and moderate EPH gestosis, while the plasma taurine concentration did not change significantly. Taurine uptake in platelets paralleled the severity of EPH gestosis. The Vmax of the uptake in severe EPH gestosis was about 2.4 times higher than that in normal pregnancy or mild and moderate EPH gestosis, but no significant difference was seen in the Km value among these groups.
