Adrenergic effect on women's blood neutrophil oxidative activity the first day after delivery.

Objective: Recent studies have described a significant role for neutrophils in reproductive processes and their participation in the preparation of the cervix for childbirth and the activation of labor, in the postpartum involution of the uterus, and in the occurrence of preeclampsia. This study aimed to assess the formation of free radicals by neutrophils in the blood of women on the first day after childbirth and to characterize the adrenergic effect on this process.

Methods: Venous blood samples from 100 female volunteers aged 26-32 years who had 2 or 3 full-term deliveries were collected and analyzed.

Cryoprotective Effect of Pectin Tanacetan from L.

We researched the ability of tanacetan pectin from inflorescences of common tansy L. to change the osmolarity and freezing point of water in solutions of cryoprotectants: glycerol-3.5%, dimethyl sulfoxide (DMSO)-10%, dimethylacetamide-10% (DMAC), and 1.

Apple Pectin as a New Component for Cryopreservation of Nucleated Cells.

This study explored the ability of apple pectin AU-701 to change the freezing point of water in cryoprotectant solutions with different penetrating abilities using glycerol, dimethyl sulfoxide (DMSO), 1,2-propanediol (1,2-PD), dimethyl acetamide (DMAC), hydroxyethyl starch (HES), hexamethylenebistetraoxyethylurea (or substance A-378), and in biological fluid (human venous blood). An effective interaction was used to protect human blood leukocytes at ultrafreezer temperature (-80°C). Apple pectin affects the freezing temperature of water in different ways and it depends on the medium in which it is dissolved, as it either slows down the freezing process (in glycerol) or accelerates it (venous blood).

Effect of Pectins on Water Crystallization Pattern and Integrity of Cells During Freezing.

The ability of various pectin polysaccharides to modify the morphological structure of ice during the phase transitions from water to ice was studied. Pectins were isolated from Sosnowsky's hogweed Heracleum sosnowskyi Manden (heracleuman-N6HS), tansy Tanacetum vulgare L. (tanacetan-N7TVF), and Rauwolfia serpentina Benth callus (rauwolfian-N8RS).
