DMSO-Free Cryopreservation of Human Umbilical Cord Tissue.

Human umbilical cord represents a source of multipotent stromal cells of a supreme therapeutic potential. The cells can be isolated from either fresh or cryopreserved umbilical cord tissues. DMSO is a cryoprotectant most commonly used for preservation of umbilical cord tissues; however, cyto- and genotoxicity of this compound is evident and well documented.

Comparison of the Expression Profiles of Immune Response Gene mRNA in Umbilical and Venous Blood of Newborns of the First Day of Life.

The expression of immune response gene mRNA in the umbilical and venous blood were compared in newborns of the first day of life with and without signs of infection. The expression of il1b, il6, il8, il10, il12a, il15, il18, tnfa, tgfb1, tbx21, gata3, foxp3, rorc2, cd45, cd68, cd69, tlr2, tlr4, tlr9, and mmp8 mRNA was evaluated in umbilical and venous blood cells of newborns by reverse transcription real time PCR. In full-term newborns without signs of infection, the expression of il8, tlr2, tlr4, and mmp8 in venous blood was higher than in umbilical blood, while in preterm newborns, the levels of mmp8 transcript were elevated while the levels of tlr9, cd45, and gata3 were reduced.

[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.
