[Immunologic factors in the serum and peritoneal fluid in women after laparoscopy. I. Nonspecific factors]. / Sledování nekterých faktoru imunity v séru a v peritoneální tekutine u laparoskopovaných zen. I. Nespecifické faktory.

The authors examined by diagnostic laparoscopy and immunologically 180 patients in 1993-1995. They assessed in serum and peritoneal fluid IgG, IgA, IgM, haptoglobulin, A2-macroglobulin, A1-antitrypsin, transferrin, C4- and C3-complement, orosomucoid, A2AP-glycoprotein, albumin, prealbumin and hemopexin. The authors found that some individual pathological results as regards non-specific immunity supplement the clinical diagnosis, in particular in endomeriosis, multiple adhesions, polycystic ovaries and chronic anovulation.

[Monitoring immunity factors in serum and peritoneal fluid after laparoscopy in women. II. Sperm and zona pellucida antibodies]. / Sledování nekterých faktoru imunity v séru a v peritoneální tekutine u laparoskopovaných zen--II. Protilátky proti spermiím a proti zona pellucida.

A team of authors investigated antibody levels against spermatozoa and against the zona pellucida in sera and peritoneal fluids in infertile women where diagnostic laparoscopy was indicated. The immunological cause of infertility was diagnosed in some women with a normal laparoscopic finding on the inner genital, as well as in patients with endometriosis and in women with adhesions. A minimal antibody response to antigens of gametes was recorded in women with the diagnosis of uterus myomatosus, uterus hypoplasticus and polycystic ovary. The authors present detailed findings on antibodies in different groups of patients.

Effect of a pause on action potentials of the working ventricular myocardium of human embryos.

The effect of a period of rest (Tp) lasting from 5 to 120 s on the action potentials (AP) of the ventricular myocardium of 9- to 11-week human embryos was studied. The result was shortening of the AP proportional to the duration of the pause and it was accompanied by a shift of the AP plateau phase to more negative membrane voltages. Shortening of the AP during the pause was more pronounced in solutions with a half extracellular calcium concentration. Recovery from the effect of the pause took place significantly more slowly in solutions with the lower extracellular calcium concentration than in the presence of a normal concentration.
