Цель исследования - изучение особенностей обмена гистамина при хронической тазовой боли у пациенток с наружным генитальным эндометриозом. Методика. В сыворотке крови 100 пациенток методом высокоточного (в нг/мл) иммуноферментного твердофазного анализа определяли концентрацию гистамина. Использованы реактивы «Histamine ЕLISA», аппарат BAE-1000 Гистамин (Labor Diagnostika Nord - LDN, Германия). Оценка выраженности болевого синдрома осуществлялась по шкале ВАШ, оценка качества жизни - на основании опросника для оценки качества жизни при эндометриозе (EHR-30), оценка тревожности - опросника Спилбергера-Ханина. Результаты. Показано статистически значимое повышение уровня гистамина у пациенток с высокой интенсивностью болевого синдрома. Женщины с наружным генитальным эндометриозом, сопровождающимся интенсивным болевым синдромом в 100% случаев обнаруживали высокие уровни ситуативной и личностной тревожности, тогда как, лишь у 40% женщин (n = 16) контрольной группы выявлен умеренный уровень тревожности. Депрессивные расстройства выявлены у 58,3% женщин с хронической тазовой болью (n = 35), из них основную часть (n = 20) составили женщины с выраженной степенью болевого синдрома по ВАШ. Заключение. Психоэмоциональное состояние женщин с тазовой болью, ассоциированной с наружным генитальным эндометриозом, характеризуется высокими уровнями депрессивных и тревожных расстройств, значительным снижением уровня качества жизни. Выявлена прямая связь между интенсивностью болевого синдрома и уровнем гистамина в периферической крови пациенток с наружным генитальным эндометриозом. Objective. To study features of histamine metabolism in patients with chronic pelvic pain associated with external genital endometriosis. Methods. For quantitative assessment of histamine level in peripheral blood was taken from 100 patients which than was centrifuged. In blood serum histamine concentration was determined by enzyme-linked immunosorbent assay method with reagents «Histamine ЕLISA» on the machine BAE-1000 Histamine (Labor Diagnostika Nord - LDN, Hermany). A pain syndrome was assessed by Visual Analog Scale (VAS), quality of life assessment - by Endometriosis Health Profile Questionnaire (EHR-30), level of anxiety was determined by Spielberger-Khanin questionnaire. The results. Showed statistically higher histamine level in patients with severe pain according to VAS. After assessment of results obtained from Spielberger-Khanin questionnaire 100% experimental group’s women with external genital endometriosis (n = 60) were noted to be have high level of state and trait anxiety, then 40% women of control group (n = 16) have moderate level of anxiety. The incidence of depression in women with chronic pelvic pain was 58.3% (n = 35) and the main part (n = 20) were women with severe stage of pelvic pain according to VAS. Conclusions. Psycho emotional condition of women with external genital endometriosis associated pelvic pain characterized by higher depression and anxiety levels, with significant decrease quality of life. Direct relationship also was found between pain syndrome intensity and histamine level in peripheral blood in patients with external genital endometriosis.

Abstract The hyper-gene conversion srs2-101 mutation of the SRS2 DNA helicase gene of Saccharomyces cerevisiae has been reported to suppress the UV sensitivity of rad18 mutants. New alleles of SRS2 were recovered using this suppressor phenotype. The alleles have been characterized with respect to suppression of rad18 UV sensitivity, hyperrecombination, reduction of meiotic viability, and definition of the mutational change within the SRS2 gene. Variability in the degree of rad18 suppression and hyperrecombination were found. The alleles that showed the severest effects were found to be missense mutations within the consensus domains of the DNA helicase family of proteins. The effect of mutations in domains I (ATP-binding) and V (proposed DNA binding) are reported. Some alleles of SRS2 reduce spore viability to 50% of wild-type levels. This phenotype is not bypassed by spo13 mutation. Although the srs2 homozygous diploids strains undergo normal commitment to meiotic recombination, this event is delayed by several hours in the mutant strains and the strains appear to stall in the progression from meiosis I to meiosis II.

The basic nature of guanethidine and some of its effects suggested a possible action of this drug on histamine metabolism. A single intraperitoneal injection of guanethidine (10 mg/kg) in male rats was found to double the daily urinary excretion of free histamine; daily injection for three weeks caused a 10-fold increase. In male rats, guanethidine increased the number of mast cells in the peritoneal fluid and, in both peritoneal fluid and mesentery, caused a significant degranulation of these cells; this action was not observed in female rats. This finding may indicate that guanethidine blocks methylation of histamine by inhibiting imidazole methyl transferase since this enzyme is found in male but not in female rats. Bethanidine and reserpine had no effect on histamine excretion. Imidazole was found to be even more potent than guanethidine in causing an increase in urinary histamine. Guanethidine and imidazole neither potentiated nor mimicked the action of histamine on the isolated ileum.
