Nitroimidazoles have been shown to be the drugs of choice treat women with bacterial vaginosis, but recurrence rate is high. Some workers suggested that symptoms may in fact reinfection by male consorts, no controlled studies undertaken confirm this. In an international, multicentre, randomised, double blind trial, was studied 241 a clinical diagnosis vaginosis. All were treated 2 g metronidazole twice at interval two days. The patients randomly allocated groups, one contained 123 women,...

Rhinovirus is the most common virus causing respiratory tract illnesses in children. Rhinoviruses are classified into species A, B and C. We examined associations between different rhinovirus illness severity.This a retrospective observational cohort study on confirmed infections 134 children 3-23 months of age, who were enrolled 2 prospective studies bronchiolitis acute otitis media, respectively, conducted simultaneously Turku University Hospital, Turku, Finland, September 2007 December...

We studied the effects of spinal anaesthesia (Group S), epidural E), and combined SE), on maternal fetal blood flow in 24 healthy parturients (n = 8/group) with uncomplicated singleton pregnancies using Doppler technique. Prior to induction anaesthesia, patients were prehydrated balanced electrolyte solution 15 ml kg ‐1 over a period min. After regional systolic pressure was maintained within 15% limits preoperative values prophylactic etilefrine infusion Groups S SE. The velocity waveforms...

Abstract We measured concentrations of free thyroxin (FT4) in serum by using two new two-step FT4 assays--a solid-phase radioimmunoassay. Spectria, and a time-resolved fluoroimmunoassay. Delfia--and compared the results with those assay (RIA-gnost), one-step analog (Amerlex-M), after equilibrium dialysis. The assays classified 30 hypothyroid 43 hyperthyroid patients (untreated) well. In 138 nonthyroidal illness (NTI) late pregnancy (n = 36), fewer subnormal values were reported Spectria (P...

Female hyperandrogenism is often associated with hyperinsulinaemia and insulin resistance. We evaluated the hormone responses in an oral glucose tolerance test to investigate interactions of gonadotrophins, insulin, C-peptide androgens women polycystic ovarian disease (PCOD). In 28 patients ultrasonographically diagnosed PCOD, resistance were mainly obesity. Both basal cumulative sum ratios high obese subjects, suggesting decreasing hepatic removal caused by Nevertheless, some lean PCOD...

Cardiovascular risk factors are often ineffectively controlled in hypertensive postmenopausal women, and moreover, some antihypertensive drugs may increase particular such as insulin resistance. In a multicenter, multinational (Finland, Sweden, Lithuania), double-blind, prospectively randomized study obese women without hormone therapy (n = 98) were randomly assigned to receive treatment with either the centrally acting agent moxonidine, 0.6 mg/day, or peripherally atenolol, 50 for 8 weeks....

Seventeen healthy women received a combination of 0.030 mg ethinyl estradiol and 0.150 levonorgestrel or desogestrel for 2 years as oral contraception. Serum levels sex hormone binding globulin, transcortin, ceruloplasmin, pregnancy-associated protein were measured before contraception, during 3, 6, 12, 18, 24 months treatment, after stopping the pill. Oral contraception with both preparations induced similar, significant rise in ceruloplasmin protein. Sex globulin rose significantly...

Serum concentrations of copper (Cu) and zinc (Zn) were determined in 20 non-pregnant healthy menstruating women pregnant during the 1st, 2nd 3rd trimesters 5 weeks postpartum as a longitudinal study. Also cross-sectional population 106 was studied. Further, Cu Zn measured 13 who gave birth to small-for-date (SFD) infants; this done trimester pregnancy. The serum concentration nonpregnant 0.91 ± 0.19 mg/l. During pregnancy it significantly higher (1.48 0.31, 1.91 0.25 2.20 0.36 mg/l...

The responses of the common internal iliac artery and middle uterine pregnant horn to continuous infusions graded doses norepinephrine, epinephrine, dopamine, isoxsuprine, angiotensin nitroprusside were investigated in chronically instrumented ewes. Norepinephrine progressively decreased blood flow increased resistance both vessels but changes more marked artery. Isoxsuprine epinephrine had an insignificant effect on flow, that Nitroprusside proportionately. Angiotensin less than 0.16...

OBJECTIVE: To determine whether the ovary influences adrenal androgen secretion in women with polycystic syndrome (PCOS). DESIGN: Six PCOS-affected patients clomiphene resistance and gonadotrophin hyperresponsivity, six controls regular ovulatory cycles, matched for age body mass index. METHODS: Bilateral ovarian wedge resection was performed to induce ovulation surgically these refractory PCOS. The secretions were evaluated PCOS before again 6 months after this surgery, controls, using an...

The circulatory responses to progressively increasing doses of angiotensin II were studied in the same group chronically instrumented unanesthetized pregnant sheep during three consecutive periods: a) normotensive with intact kidneys; b) unilateral nephrectomy; and c) one-kidney hypertension. results show that 1) pressor response a given dose was significantly greater than hypertensive condition; 2) uterine blood flow decreased markedly development hypertension; 3) depended on dosage; less...
