PURPOSE: Evaluate the effects of ipriflavone during fetogenesis, since no studies have been conducted to assess its effect during this period. METHODS: 60 pregnant rats were divided randomly into four groups (n=15). G-control (1 mL of distilled water) and three groups treated intragastrically with ipriflavone from the 16th to the 20th post coitus (PC) day: G-300 (300 mg/kg), G-1,500 (1,500 mg/kg) and G-3,000 (3,000 mg/kg). The animals were weighed, anaesthetized intraperitoneally with xylazine and ketamine at doses of 180 mg/kg and 10 mg/kg, respectively, and sacrificed by total exsanguination on the 21st day. A complete blood count was performed and serum cholesterol, triglycerides, AST, ALT, urea, creatinine, and glucose were determined in pregnant rats. After laparotomy, the liver, kidneys, adrenals, spleen and ovaries were removed and weighed; fetuses and placentas were also weighed to obtain the average weight of the litters. Four fetuses (two males and two females) were chosen at random for the determination of the length and weight of brain, liver, kidneys and lungs. Statistical analysis: ANOVA followed by Dunnett's test. For raw data without normal distribution and homoscedasticity, we used the Kruskal-Wallis test followed by the Mann-Whitney test. Proportions were analyzed by the χ² test (p<0.05). RESULTS: Triglyceride levels (mg/dL) were: Control-G (138.8±21.8), G-300 (211.2±63.9) G-1,500 (251.5±65.2) G-3,000 (217.7±49.6); p<0.05. The body weight of fetuses (g) was: G-Control (male 3.3±0.3; female 3.1±0.3), G-300 (male 3.4±0.2; female 3.1±0.4), G-1,500 (male 3.5±0.3; female 3.2±0.3), G-3,000 (male 3.4±0.5; female 3.1±0.4). CONCLUSION: Ipriflavone did not cause maternal toxicity, but increased triglyceride levels and reduced hematocrit at higher doses. The body and organ weights of the fetuses did not change with dam treatment. There were no external malformations or fetal deaths.

PURPOSE: to determine the prevalence of depression and anxiety in climacteric women and the probable factors responsible for its occurrence. METHODS: a transversal study that has selected 93 women attended at a climacteric outpatient clinic, from May 2006 to August 2007. Inclusion criteria were: women from 40 to 65 years old who agreed with participating in the project. Exclusion criteria: patients in hormonal therapy, hormone-therapy by implant, DIUs and depo injections in the preceding six months, endocrinopathies leading to menstrual irregularities, hepatopathies, thrombopathies, use of drugs which interfere in the menstrual cycle, anxiolytics and antidepressants (as their use indicates previous diagnosis of mood disorders), hysterectomy, oophorectomy, cancer or psychiatric disease, and patients who had been submitted to radio or chemotherapy. During the interview, four questionnaires were applied: Anamnesis, containing socio-demographic, clinical and living habits data; Blatt-Kupperman's Menopausal Index for climacteric syndrome diagnosis; Anxiety sub-scale of the Hospital Anxiety and Depression scale (HADS-A) for anxiety diagnosis; and Beck's Depression Inventory for the diagnosis of depression. Descriptive and correlation analysis among the variables, χ2 and Hosmer-Lemeshow tests were performed using the Statistica Software program, version 6. RESULTS: the average depression prevalence among the patients was 36.8%, while that of anxiety was 53.7%. There was no significant difference between the prevalence of depression and anxiety in the three phases of climacterium. There was a significant relationship between the presence of moderate climacteric symptoms and the presence of mood alterations (p<0.001). Depression was more frequent in women with anxiety (OR=4.2) and insomnia (OR=4.9), having a job being a protection factor (OR=0.2). Risk factors related to anxiety were the presence of depression (OR=6.1) and antecedents of pre-menstrual tension (OR=7.0). CONCLUSIONS: the prevalence of depression and anxiety is high in climacterium, being possible to detect risk factors related to their occurrence.

PURPOSE: to evaluate the effect of exposure of female rats to therapeutic ultrasound in the pre-implantation phase. METHODS: pregnant Wistar female rats have been exposed to 3 MHz, 0.6 W/cm² ultrasound, pulsatile ultrasound (PUS) or continuous ultrasound (CUS), and controls, unplugged ultrasound (UUS), for five minutes. The rats were sacrificed at the 20th day post-insemination. Biochemical and hematological analyses have been done. Animals have been submitted to necropsy in order to identify lesions of internal organs, and to remove and weight the liver, kidneys and ovaries. Alive, malformed, dead and reabsorbed fetuses have been counted. RESULTS: the rats have not presented changes in their body and organs weight, and neither in their reproductive capacity, but there has been an increase in triglycerides in the PUS and CUS groups, when compared to the UUS group. The fetuses' relative weights of the heart (0.7 ± 0.9), liver (9.8 ± 0.8), kidneys (6.2 ± 0.8) and lungs (3.8 ± 0.4) increased in the CUS, when compared to the heart (0.7 ± 0.9), liver (9.8 ± 0.8), kidneys (6.2 ± 0.8) e lungs (3.8 ± 0.4) of the UUS. CONCLUSIONS: in the experimental model, the therapeutic ultrasound used has not caused meaningful maternal toxicity. Pulsatile waves have not changed fetal morphology, but continuous waves have caused increase in the relative weight of the fetuses' heart, liver, lungs and kidneys.

PURPOSE: to evaluate the toxicity of tacrolimus on embryonic development in rats treated during the tubal transit period. METHODS: sixty Wistar rats were distributed into four groups (15 animals each), which received different doses of tacrolimus through intragastric administration: (T1) 1.0 mg/kg/day, (T2) 2.0 mg/kg/day and (T3) 4.0 mg/kg/day. The control group (C) received distilled water. The rats were observed daily to detect clinical signs of toxicity. The treatments were performed from the first to the fifth day of pregnancy. The following maternal variables were analyzed: body, ovary, liver, and kidney weights, food intake, number of corpora lutea, implants, alive and dead fetuses, and implantation rates. The fetuses and placentae were weighed and the former were observed in order to detect external malformation. Statistical analysis was performed by one way: analysis of variance (ANOVA), folowed by the Dunnet test (alpha=0.05). RESULTS: there were no signs of maternal toxicity, such as body weight loss, decrease in food intake or in organ weights (p>0.05). There was also no significant difference among weights of fetuses (C: 1.8±0.6; T1: 2.2±0.5; T2: 1.9±0.5 and T3: 2.0±0.5 g) and placentae (C: 1,6±0.4; T1: 1.5±0.4; T2: 1.8±0.4 e T3: 1.6±0.4 g), with p>0.05; no external malformation was detected in the fetuses. CONCLUSIONS: the administration of tacrolimus to pregnant rats during the tubal transit period does not seem to generate any toxic effect to mother or embryo.

PURPOSE: to evaluate all maternal deaths that occurred between 1927 and 2001, among 164,161 patients admitted to the Maternidade Therezinha de Jesus, the obstetrical service of the "Universidade Federal de Juiz de Fora", Brazil. METHODS: a retrospective study of 144 maternal deaths that occurred in the maternity hospital in 75 years, with 131,048 live births in the same period of time, analyzing all patients's records regarding their clinical history and data from death certificates. Autopsies were not performed. Data obtained were age, parity, gestation length, complications, moment, and causes of death. The index of maternal mortality (IMM) period 100 thousand live births was utilized. For statistical analysis the chi2 test and the exponential smoothing technique were used (alpha=0.05). RESULTS: IMM decreased from 1544 in the period 1927-1941 to 314 (p<0.001) between 1942 and 1956 and from 1957 to 1971 it was reduced to 76.4 per 100 thousand live births (p<0.001). Nevertheless, since 1972 there was no further significant improvement (IMM=46 in the last 15 years, p=0.139). Maternal mortality was more frequent in the 15 to 39 years age group, in nulliparous patients with term pregnancies and mostly in the immediate postpartum period (53%). Direct obstetric causes occurred in 79.3% and indirect causes in 20.7% of the cases. Analyzing the evolution of the causes of death, it was found that in the first period of time the most frequent direct obstetric causes in descending order were puerperal infection, eclampsia and uterine rupture, while in the second period they were prepartum hemorrhage and eclampsia, and from 1977 to 2001 hemorrhage, abortion and preeclampsia. Analysis of the past 15 years showed the absence of maternal deaths by either preeclampsia or puerperal infection and the main causes were peripartum hemorrhage, abortion and indirect obstetrical causes. Relating maternal mortality to the type of delivery by the relative risk between cesarean section and vaginal delivery, it was found that when the indication of cesarean section is inevitable its risk is lower (relative risk = 0.6) than through vaginal delivery. CONCLUSIONS: despite the reduction along the 75 years of study, maternal mortality of 46 per 100,000 live births is still very high, and there was no significant decrease since 1972. Many deaths are avoidable. Hemorrhage is at present the most frequent cause of maternal death, the decision to intervene should be fast, and a proper indication for a cesarean section is a safe option. Maternal mortality caused by abortion is increasing alarmingly and family planning is essential.
