[Comparative analysis of serum analyte level measurements by commercial diagnostic kits from four manufacturers (Alkor-Bio, Roche, Diagnostic Products Corporation-DCP, and Bayer Corporation)].

Hydrocortisone, progesterone, testosterone, triiodothyronine, thyroxine, chorionic gonadotropin, prolactin, alpha-fetoprotein, luteinizing, follicle-stimulating, and thyrotropic hormones were measured in human sera and in Lyphochek Immunoassay Plus Control reference sera (Bio-Rad Laboratories, USA) using 4 commercial kits (Alkor Bio Inc. and Roche, automated analyzer Roche Cobas Core; DPC, automated analyzer Immulite; Bayer, automated analyzer ACS:180). Coordination and correlation between these kits was observed, the coordination decreasing in the series Alkor Bio/Bayer, Alkor Bio/Roche, and Alkor Bio/DPC.

[The clinical use of andriol in the hormonal therapy of male sterility].

The paper presents the experience in administration of testosterone andekanoate (andriol) in males suffering from infertility due to idiopathic oligozoospermia. Andriol produced a positive effect on ejaculate. As a result, 25% of the wives got pregnant.

[An intensive regimen of supersonic-frequency-current therapy in chronic inflammation of the adnexa uteri].

As shown by clinical, electrophysiological and hormonal examinations of 34 patients with chronic inflammation of the uterine appendages and control subjects, the disease treatment with intensive low-frequency current has no negative effects on cardiovascular and endocrine systems, improves function of the reproductive system. Intensive low-frequency currents are believed to be a useful modality in management of chronic genital inflammation.

[The determination of CA-125, CA-19-9 and CEA antigens in gynecologic patients for differential diagnosis and the assessment of the efficacy of surgical treatment and subsequent monitoring].

Tumor markers CA 125, CA 19-9, and carcinoembryonic antigen (CEA) were measured in the blood sera of 396 inpatients of different age. In 139 patients the measurements were carried out over time. Hoffman La Roche enzyme immunoassay test kits were used.

[The steroid content of the amniotic fluid in the 1st and 2nd pregnancy trimesters in 21-hydroxylase insufficiency and in fetal central nervous system defects].

A total of 103 samples of amniotic fluid obtained by transabdominal amniocentesis were examined, 52 of these from women at a high risk of giving birth to children with congenital adrenal hyperplasia due to 21-hydroxylase (21-OH) deficiency and 30 ones with fetuses with different neural tube malformations. 17-Hydroxyprogesterone was found to be a reliable marker indicating the disease in fetuses from the group at risk of hereditary 21-OH deficiency. This marker can be effectively used as early as in the 1 gestation trimester.

[Diagnosis of heterozygote carrier of mutant gene of 21-hydroxylase].

Heterozygotic carriers of 21-hydroxylase deficiency were detected by prolonged ACTH stimulation test. Stepwise discriminant analysis was used for data processing, which helped derive a function: D = 0.052 x X1 + 0.

[Hypogonadotropic form of amenorrhea. Principles of ovulation induction].

Analysis of the clinico-anamnestic and endocrine parameters of the reproductive system of 45 patients with hypogonadotropic amenorrhea helped single out three types of this condition. Drug doses and schemes of their administration to induce ovulation were selected individually with due consideration for the initial functional status of the reproductive system. The authors defined the basic principles of ovulation induction in patients with hypogonadotropic amenorrhea: the patients should be carefully selected according to WHO classification, with due regard for their clinico-anamnestic data and the function of the reproductive system (hormonal functional test); drug doses for substitution therapy and protocols of their administration should be selected individually, with consideration for the degree of hypophyseal-gonadal insufficiency; daily double (ultrasonic and hormonal) monitoring is needed for the correction of ovulation induction protocols; the choice of the optimal time of administration of the "ovulatory" dose should be based on the findings of double monitoring indicating follicle size 19-20 mm and the maximal activity of steroidogenesis (350 to 400 pmol/liter estradiol per follicle).

[Hypogonadotropic form of amenorrhea. Features of the functional state of hypothalamo-hypophyseal structures and the endocrine status].

Study of the function of the hypothalamopituitary system in patients with hypogonadotrophic amenorrhea showed the activity of its structures which manifested by the presence of pulsed LH secretion in 70% of women; however, the parameters of pulsed secretion of gonadotropins were disordered: the pulses were chaotic and low-amplitude. Adenohypophyseal gonadotrophs were capable of reacting to the administered gonadotrophin-releasing hormone, but the parameters of this reaction differed from the normal. The endocrine status of patients with hypogonadotrophic amenorrhea was changed vs.

[Congenital dysfunction of adrenal cortex - detection of new mutant gene of 21-hydroxylase].

The paper presents the results of investigations of 30 Slavic families with different types of congenial adrenal hyperplasia (CAH). The classic types of CAH were established to be associated with HLA B14 in most cases. This fact proves the presence of new mutation of 21-hydroxylase (21-OH) gene.

Hormonal and immunologic methods in the diagnosis and treatment of patients with benign ovarian tumors and endometriotic cysts.

Objective: To compare efficacy of various methods for characterizing endometriosis and benign ovarian tumors.

Design: Two parallel groups of patients, 54 with endometriotic ovarian cysts and 48 with benign tumors.

Setting: Central clinic.

[The characteristics of hypophyseal gonadotropic function in patients with hypogonadotropic amenorrhea against a background of pergonal ovulation stimulation].

Forty-three ovulation cycles stimulated with human menopausal gonadotropin were examined in 31 patients with hypogonadotropic amenorrhea. Peripheral blood estradiol and luteinizing hormone were radioimmunoassayed. The findings indicate the possibility of recovery of adenohypophyseal gonadotropin autosecretion in the presence of human menopausal gonadotropin administration.

[The effect of a decrease in body weight in patients with the polycystic ovary syndrome].

Eighty patients with the polycystic ovaries syndrome and excessive body mass were examined. In 60 patients body mass reduction resulted from diets and in 20 it occurred over the course of acupuncture. Such treatment resulted in pregnancy in 27 (33.

[Pulsed secretion of gonadotropins in polycystic ovary syndrome].

Pulsed secretion of gonadotropins was studied in 8 women suffering from polycystic ovarian syndrome, aged 23-28. Data on the time course of LH and FSH levels were processes by Santen and Bardin's method and by harmonic analysis. The results evidence that regular ejections of LH at a frequency higher than circahoralian rhythm (about 2 impulses per h) in such patients may be the cause of the development of the polycystic ovarian syndrome.

[The functional characteristics of the reproductive system in women who are heterozygous carriers of 21-hydroxylase deficiency].

This paper reports the results of evaluation of reproductive histories of 52 heterozygous female carriers of 21-hydroxylase deficiency who gave birth to children with classic congenital adrenocortical hyperplasia. Functional ACTH adrenal tests of these women were compared with those in a control group of noncarriers. Test findings are discussed with respect to the pathogenesis of reproductive tract disorders in the carriers of a mutant gene.

[Anatomic and functional characteristics of resistant ovaries].

Resistant ovary syndrome has been confirmed in 42 women using clinical, roentgenologic (craniography, hysterosalpingography, pneumogynecography, electroencephalography), genetic, sonographic, endoscopic and histologic studies. Fibrocystic breast disease was identified in 64% and normal ovarian size in 74% of the patients with resistant ovary syndrome. Progesterone test was positive in 84% of the patients.

[The hypothalamo-hypophyseal system in resistant ovary syndrome].

The study has been done in 30 women with the resistant ovary syndrome diagnosed by laparoscopy, laparotomy and histologic examination of ovarian biopsy samples. Genetic study identified the feminine phenotype and genotype (46,XX). Estradiol levels corresponded to those seen in the follicular menstrual phase, prolactin levels were normal, and gonadotropin levels were above basal values and were several fold above the ovulatory peak, when tested with luteinizing hormone-releasing factor in 7 patients and after estrogen challenge in 5 patients.

[Prospects of the use of neoplasm antigens as markers of gynecologic diseases].

CA-125 antigen was assayed in 108 patients with the most prevalent gynecologic diseases by enzyme immunoassay. Its blood levels were found to be under 35 U/ml in the patients with inflammatory diseases. In endometriosis and benign ovarian tumors CA-125 concentrations in the blood were elevated.

[The polycystic ovary syndrome and increased body mass].

Eighty patients with the polycystic ovarys syndrome (PCOS) and excessive body weight were investigated. Weight loss was achieved by means of a diet in 60 patients, and acupuncture in 20 patients. This kind of treatment resulted in pregnancy in 27 (33.
