Expression of stem cell markers on mononuclear cells derived from heparinized cadaveric organ donors before and after disconnection from the respirator.

We have attempted to evaluate the level of the earliest human hematopoietic cell marker expression (CD34, CD117, CD133, CD184) on cells obtained from heparinized cadaveric organ donors before and after disconnection from the respirator. Moreover, we compared various cell populations: (1) coexpressing CD34/CD117; (2) CD34/CD133; (3) highly enriched hematopoietic stem cells (CD34+CXCR4+CD45+); and (4) highly enriched tissue-committed stem cells (CD34+CXCR4+CD45-). Finally, we analyzed whether the level of hematopoietic stem cell marker expression depended on the age of the donor.

[Arteries of the uterine cervix in reproductive age in microangiographic studies].

Objectives: The main aim of our research was the estimation of cervical arteries in women in the reproductive age.

Materials And Methods: Study was performed on 61 cases of organs taken, during autopsies, from the minor pelvis composing the female genital organs, urinary bladder, rectum and the upper part of the vagina from women aged 18 to 41. The material was divided in two groups: mothers and non mothers.

[Arteries of the hilum and parenchymal part of the ovary in reproductive age in microangiographic studies].

Objectives: The main aim of ours research was to recognize the arterial system of female ovaries in women in the reproductive age.

Materials And Methods: Study was performed on 31 cases of organs taken from the minor pelvis, composing female genital organs, urinary bladder, rectum and the upper part of the vagina from women aged 15 to 40. The ovarian and the uterine arteries have been injected with fine-granular radiological contrast medium Hexabrix 200 and Ultravist 370.

[Arterial vasculature of ovaries in women of various ages in light of anatomic, radiologic and microangiographic examinations].

This study was done in 101 internal genital organs without any underlying pathology, collected en block from girls and women aged 3 to 85 years. Five groups were formed, depending on age, obstetric and gynecological history (Tab. 1).

Analogues of arginine vasopressin modified in position 2 or 3 with naphthylalanine: selective antagonists of oxytocin in-vitro.

In this study we describe the synthesis and some pharmacological properties of six new analogues of arginine vasopressin (AVP). Five of the peptides were substituted in position 2 with L-1-naphthylalanine (L-1-Nal) or D-1-naphthylalanine (D-1-Nal); one had D-1-Nal in position 3. All analogues were tested in bioassays for pressor and antidiuretic activity.
