[The relation of a number of hormonal indices to risk factors for IHD and its prevalence based on the data from a large population study]. / Sviaz' riada gormonal'nykh pokazatelei s faktorami riska IBS i ee rasprostranennost'iu po dannym krupnogo populiatsionnogo issledovaniia.

Relevance of IHD risk factors and hormone concentrations (insulin, estradiol, testosterone, prolactin, LH, FSH, TTH and hydrocortisone) to IHD incidence was studied in 1200 men. Multivariate statistical analysis demonstrated that only a small number of hormonal indices are associated with main lipid and nonlipid risk factors. The relationships exist between systolic arterial pressure (SAP) and hydrocortisone, between TTH and total cholesterol, SAP and age, estradiol, testosterone and age. Significant independent associations were found between IHD prevalence and age (R = 0.140, 3 = 0.000), SAP (R = 0.130, P.0.001), HDLP cholesterol (R = -0.082, P = 0.007), height (R = -0.078, P = 0.010), insulin (R = 0.067, P = 0.035), standard deviation of estradiol from median value (R = 0.083, P = 0.017). The findings confirm a great role of high SAP in the development of IHD, a significant and independent association of high insulin levels with IHD prevalence, the presence of nonlinear relation of estradiol concentration to IHD occurrence in males.

[Characteristics of enzymatic function of the stomach in gastroduodenal diseases in children with regard to gastric carcinogenesis]. / Osobennosti fermentativnoi funktsii zheludka pri gastroduodenal'noi patologii u detei v aspekte gastrokantserogeneza.

The paper deals with a description of the biochemical properties of the isoforms of pepsinogen pepsin of gastric mucosa and blood serum in children suffering from duodenal ulcerative disease as well as in atrophic and subtrophic lesions of gastric mucosa. Atrophic gastritis was found to involve an inhibited biosynthesis of the Ist fraction of pepsinogen while ulcerative-erosive lesions of the gastro-duodenal area--an increased level of the 3rd isoform of pepsinogen.

[Hyperprolactinemia as a marker of the progression of cervical cancer]. / Giperprolaktinemiia kak marker progressii raka sheiki matki.

Elevated blood prolactin level was identified in 80% of untreated patients with advanced (stage II-IV) cervical cancer whereas it was normal at the earlier (preinvasive) stage. Patients with stage I-A, II tumors revealed either increased or normal blood prolactin level. Patients with advanced cancer who had undergone irradiation and surgery, either alone or in combination, showed hyperprolactinemia as often as 94% of the time. Studies on pathogenesis of hyperprolactinemia and its role in tumor progression are currently conducted by the authors.

[Effect of progestin therapy on the level of cytoplasmic receptors in patients with cancer of the corpus uteri]. / Vliianie progestinoterapii na uroven' tsitoplazmaticheskikh retseptorov u bol'nykh rakom tela matki.

Correlations were identified between tumor morphobiochemical characteristics and basic parameters of reproductive homeostasis in 256 cases of endometrial carcinoma. A correlation was established between the levels of cytoplasmic receptors to estradiol (ER) and progesterone (PR), on the one hand, and morphological differentiation and spontaneous secretion in tumor tissue, on the other. A direct correlation was found between ER and metastatic spread to regional lymph nodes, and no correlation--between ER and PR and major parameters of reproductive homeostasis. A significant decrease in ER, PR, gonadotropins, estradiol and colpocytological reaction indexes followed hormone therapy with hydroxyprogesterone capronate and medroxyprogesterone acetate. The criteria of endometrial carcinoma patients sensitivity to progestin therapy were as follows: ER and PR levels--more than 30.0 fmol/mg protein, estradiol--more than 30-50 pg/ml and colpocytological index--over 40%.

[The effect of hydroxyprogesterone caproate and its combination with tamoxifen on steroid hormone receptors in the tumor and on the basic parameters of reproductive homeostasis in patients with cancer of the corpus uteri]. / Vliianie oksiprogesterona kapronata i ego sochetaniia s tamoksifenom na retseptory steroidnykh gormonov v opukholi i osnovnye parametry reproduktivnogo gomeostata u bol'nykh rakom tela matki.

Oxyprogesterone capronate (OPC) was administered preoperatively to 46 patients with endometrial tumors and tamoxifen (T) + OPC--to 72 patients. Complex treatment was followed by more pronounced pathomorphosis in tumor. Both schedules inhibited gonadotropin secretion and lowered colpocytoscopic indexes. Dual effect of complex treatment (T + OPC) on the level of cytoplasmic receptors to progesterone was observed. Initially low levels rose while high ones dropped by the end of a 20-day course. Progestin treatment in endometrial carcinoma patients with relatively low estrogen levels should be complemented with tamoxifen to stimulate tumor sensitivity to progestagens.

[Characteristics of the hormonal metabolic status of patients with colonic and rectal cancer]. / Osobennosti gormonal'no-metabolicheskogo statusa u bol'nykh rakom obodochnoi i priamoi kishki.

Peculiarities of hormone-metabolic status in patients with cancer of the rectum and colon consist of 1) symptoms of cancrophilia, 2) disturbances of enteric endocrine system and 3) properties of the tumour tissue, determining first of all its hormone sensitivity. Determination of steroid hormone (estrogens and progesterone) receptors does not appear a sufficiently informative criterion of colorectal cancer tissue hormone sensitivity; the adenylate cyclase reaction to the hormonal stimulators is more informative in this respect. The data obtained may be useful in the working out of adjuvant therapy methods in cancer of colon and rectum (including hormonotherapy and metabolic rehabilitation).

[Immunological and hormono-metabolic indices in trophoblastic disease]. / Immunologicheskie i gormonal'no-metabolicheskie pokazateli pri trofoblasticheskoi bolezni.

Certain immunologic and hormono-metabolic indexes were studied in patients with hydatidiform mole and uterine choriocarcinoma. Changes in T- and B-lymphocyte ratio were observed: B-lymphocyte levels were abnormally high in hydatidiform mole while those of T-lymphocytes-low in choriocarcinoma. Blastogenic response of lymphocytes in trophoblastic disease matched the mean values in healthy females. No pronounced metabolic changes were registered in cases of trophoblastic disease (who are generally young). It was concluded that cellular immunity suppression is not associated with fat-carbohydrate metabolism disturbances in hydatidiform mole and choriocarcinoma of the uterus.

[Relation of blood lipids and insulin to body fat content, body surface area and state of the subcutaneous fatty tissue in patients with breast and lung cancer]. / Sviaz' lipidemii i insulinemii s soderzhaniem zhira v tele, poverkhnost'iu tela i sostoianiem podkozhnoi zhirovoi tkani u bol'nykh rakom molochnoi zhelezy i legkogo.

The study was concerned with an evaluation of the results of examination of 203 breast and 158 lung cancer patients. Such constitutional features as excessive body weight, body fat level and body surface area as well as adipocyte diameter and FFA profile in subcutaneous fat tissue were to be in a greater correlation with lipid (triglyceride, cholesterol and non-esterified FFA) levels than the rates of lipolysis and liposynthesis in both study groups. There may be minor differences in the mechanisms of hypertriglyceridemia development in breast and lung cancer patients. The rise in blood triglyceride level was largely due to basal hyperinsulinemia and glucocorticoid hyperproduction in lung cancer patients, whereas, in breast cancer patients it was mostly determined by resistance to insulin and an increase in body surface area contributed by lean body mass.

[Blood prolactin level of breast and endometrial cancer patients during surgical intervention]. / Uroven' prolaktina krovi u bol'nykh rakom molochnoi zhelezy i éndometriia vo vremia khirurgicheskogo vmeshatel'stva.

Abundant experimental data suggest the potentiating influence of hyperprolactinemia on the development, progression and dissemination of breast cancer, whereas hypophysectomy, immunologically- and pharmacologically-induced inhibition of prolactin has an antitumor effect. Moreover, hyperprolactinemia is caused by any kind of stress (surgical one included) as well as phenothiazine and butyrophenone treatment for neuroleptanalgesia. These findings encouraged intraoperative radioimmunologic assays of blood-prolactin levels in endometrial and breast cancer patients. The advantages offered by treatment with specific inhibitors of prolactin secretion aimed at reducing hyperprolactinemia on the day of surgery are discussed.

[Inhibition of the growth of Ehrlich transplantable carcinoma in mice by antichorionic immune serum]. / Tormozhenie rosta perevivnoi kartsinomy Erlikha u myshei antikhorionicheskoi immunoi syvorotkoi.

The literature data suggest the promotion of tumor cell implantation by chorionic gonadotropin. This hypothesis stimulated a study on the effect of antichorionic serum on the growth of Ehrlich solid carcinoma. An immune serum to chorionic gonadotropin obtained by immunization of rabbits was injected into mice with Ehrlich carcinoma transplanted under the skin of the back. Intramuscular injections of 0.1 ml were given twice a day for 14-21 days. A 45% inhibition of tumor growth (p less than 0.05) was observed after injection of serum with a high titer of antibodies to chorionic gonadotropin (1:10,000). It was matched by a much lower inhibition (21%), following injection of a low-titer serum (1:100). These results may be used as a rationale for development of an anahormone of chorionic gonadotropin for active immunization against chorionic gonadotropin.

[Summary insulin-like activity of the blood serum in breast cancer and in specific age-related pathology]. / Summarnaia insulinopodobnaia aktivnost' syvorotki krovi u bol'nykh rakom molochnoi zhelezy i pri spetsificheskoi vozrastnoi patologii.

Total insulin-like activity (ILA) was evaluated by biological testing blood serum on the basis of stimulation of glycogen synthesis in rat diaphragm in vivo. Glucose loading was followed by an increase in ILA and radioimmune insulin (RII) levels both in patients with breast fibroadenomatosis and healthy controls. However, the patients revealed an increased RII response matched by absence of ILA response, while the basal ILA was three times that in healthy controls. An elevated basal level of ILA was also observed in patients with coronary atherosclerosis and mental depression. Enhanced hyperinsulinism due to RII complementary factors, capable of insulin-like activity, may prove to be a factor in specific age-associated pathology (cancer, atherosclerosis, mental depression).

[Effect of hydroxyprogesterone caproate on immunological skin tests and on the T-lymphocytes in cancer of the corpus uteri]. / Vliianie oksiprogesteron-kapronata na kozhnye immunologicheskie testy i T-limfotsity u bol'nykh rakom tela matki.

Under study was the effect of oxyprogesterone-capronate (500 mg daily, total dosage of 10 g) on delayed cutaneous hypersensitivity reaction (DCHR) to tuberculin and candidine as well as the level of T-lymphocytes and cortisol in the peripheral blood in 34 patients with primary cancer of the corpus uteri. Prior to the treatment there was a considerable negative correlation between metabolic and immunological indices. Under OPC exposure DCHR enhanced in 62% of observations. In 7 of 12 patients the level of T-lymphocytes was increased and blood cortiol level decreased in 6 of 11 patients. 58 per cent of the observations showed a parallelism between the effect of OPC on the skin tests and the tumor histostructure, and in 8 of 12 patients on the level of T-lymphocytes and the tumor histostructure.

[Distribution of 131I-labelled growth hormone in mice of high and low cancer lines]. / Raspredelenie mechennogo 131I gormona rosta u myshei vysokorakovoi i nizkorakovoi linii.

It was shown that an uptake of the labeled STH in the mammary tissue of mice C3H is twice as that as in mice C57Bl, and by 40% higher than in mice CC57Br. In mammary tumors of mice C3H the label uptake was 30% higher than in mammary glands without any visible tumor. These facts may evidence that the hormone of growth take part in providing the conditions which contribute to the origination and development of mammary gland tumors.
