Bicornuate rudimentary uterine horns with functioning endometrium and complete cervical-vaginal agenesis coexisting with ovarian endometriosis: a case report.

Objective: To report a patient with bicornuate rudimentary uterine horns with functioning endometrium and complete cervical-vaginal agenesis coexisting with ovarian endometriosis.

Design: Case report.

Setting: University hospital.

Changes in the concentrations of receptors of insulin-like growth factor-I, epithelial growth factor, oestrogens and progestagens in adenomyosis foci, endometrium and myometrium of women during menstrual cycle.

Concentrations of receptors of insulin-like growth factor-I (IGF-I-R), epithelial growth factor (EGF-R), oestrogen (ER), and progesterone (PR) in the adenomyosis foci, endometrium and myometrium of women during the menstrual cycle were studied. Cell membrane levels of IGF-I-R and EGF-R, cytosol and nuclear oestrogen (ERc and ERn, respectively) and cytosol progesterone (PRc) receptors were assayed in 37 samples of adenomyosis foci, 46 of endometrium and 50 of myometrium using the radioligand method. It was found that concentrations of ER and PR in all studied tissues were significantly higher in the proliferative phase than in the secretory phases.

[Ulcerative colitis and pregnancy].

On the basis of literature and on the grounds of their own experience the authors presented their opinions on the coexistence of colitis ulcerosa (c.u.) and pregnancy.

[Favorable course of pregnancy in a patient two years after kidney transplantation].

A 30-year old female underwent kidney transplantation after unsuccessful 3-year dialysis for renal cortex necrosis. Immunosuppression was achieved with cyclosporin followed by azathioprine with prednisone. The patient conceived after 22 months with kidney transplantation.

Acute phase reactants and circulating immune complexes in patients with ovarian carcinoma.

Serum levels of haptoglobin (HP), sialic acid total (NAN) and lipid-bound (NAL), seromucoid (SER), its content in total protein (%SER), as well as circulating immune complexes (CIC), were measured in sera of women with ovarian carcinoma, prior to their treatment and through the course of chemotherapy, remission and recurrence of malignancy, respectively. Control groups consisted of healthy women and patients with benign tumors (ovarian cysts and uterine myomas). Pretreatment measurements of acute phase reactants discriminated cancers (FIGO stages I+II, III, IV) from healthy group, however differences between benign tumors and stages of ovarian cancer were not so distinct.

[Diagnostic value of determining alpha1 protease inhibitor and alpha2 macroglobulin in the serum of women with malignant and non-malignant ovarian tumors and uterine myomas].

In the serum of 21 women with malignant ovarian tumours, 13 with uterine myomas and 16 with cysts the concentrations were determined of alpha 1 inhibitor of proteases and alpha 2 macroglobulin by immunodiffusion, and the functional activity of both inhibitors which made possible calculation of the specific activity (units of inhibitory activity per one gram of inhibitor protein). In women with malignant tumours the specific activity of alpha 1 inhibitor was decreased, suggesting that a part of the inhibitor was functionally inactive. This decrease was statistically significant in relation to the control group and the groups of myomas and cysts, but was independent of the degree of disease progression.

Synthetic factor for evaluation of the effectiveness of the therapy in ovarian carcinoma.

The synthetic factor based on determinations of 10 parameters in sera of patients with ovarian carcinoma, was constructed. The factor was found to be useful in evaluation of the effectiveness of the cytotoxic treatment and in indication of the recurrence of the malignancy. Reduction of the number of biochemical markers to five (haptoglobin, seromucoid, lactate dehydrogenase, alkaline phosphatase, aspartate aminotransferase), according to significance of particular markers in the laboratory diagnostics of ovarian cancer did not affect the diagnostic sensitivity of the synthetic factor.

Abnormalities of cobalt-activated acylase from human sarcoma, carcinoma and the adjacent tissue.

Cobalt-activated acylase form-2 from human uterine myosarcoma, lung adenocarcinoma and the adjacent tissue was isolated, purified and characterized. It was found, that the enzyme from the malignant neoplasms differed both from the normal tissue and benign tumor acylase-2 in its Km value, temperature optimum and effect of some ions. Some abnormal properties (pH dependence, activation by cobalt and thermostability) were common for benign and malignant tumors.

Cobalt-activated acylase from human uterine myoma.

Cobalt-activated acylase was isolated from human uterine muscle and myoma. The enzyme was purified by ammonium sulphate precipitation, and subsequent chromatography on DEAE-cellulose, Sephadex G-150 and DEAE-Sephadex. The comparison of muscle acylase and acylase obtained from myoma has shown differences in the enzyme stability, the dependence of activity on pH and in the susceptibility to the effect of activators and inhibitors.

Serum enzymes in ovarian carcinoma.

The following enzymatic activities were measured in serum of patients with benign and malignant ovarian tumors before treatment: alkaline and acid phosphatases, aspartyl (AspAT) and alanyl (AlAT) aminotransferases, leucyl (LAP) and alanyl (AAP) aminopeptidases, lactate dehydrogenase (LDH), gamma-glutamyl transpeptidase, cathepsin, alkaline ribonuclease (RNase) and beta-glucuronidase. It was shown that at least three determinations (phosphatases and LAP) are practically useless in a discrimination between the examined groups. RNase in combination with AspAT (AlAT) or RNase with AAP and LDH were found to give the best results as marker enzymes.
