Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Infections, particularly on the gastrointestinal tract, has been known to be one of the leading causes of death in preterm infants. This is due to the immaturity of the intestinal epithelial cells. Recent studies have shown that polyamines have a role on the development of cells during embryonal phase. By this experimental study, the investigators would like to evaluate the administration of spermine on the maturation of premature fetal gut epithelial tight junction.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This experimental study is conducted with minimum 24 subjects which divided into 6 groups; 1) 24-days pregnant and is given prenatal spermine, 2) 26-days pregnant and is given prenatal spermine, 3) 28-days pregnant and is given prenatal spermine, 4) 24-days pregnant and is not given prenatal spermine, 5) 26-days pregnant and is not given prenatal spermine, and 6) 28-days pregnant and is not given prenatal spermine. At the end of desired pregnancy period, hysterectomy is done and fetus are born. From each parent subject, three fetal samples are chosen using a random sampling. Intestinal tissues are taken from each fetal sample to be examined. Several data will be collected i.e. occludin, β-catenin, and β-actin, as well as histological morphologies.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

24-Day Spermine Group

Subjects are given prenatal spermine (20 mg per body weight) during 24 days of pregnancy. On day 24 pregnancy is terminated and intestinal tissue sample is taken to be examined.

Group Type EXPERIMENTAL

Spermine

Intervention Type BIOLOGICAL

Spermine is a polyamine. It is an organic molecule that is involved in cellular metabolism and development.

26-Day Spermine Group

Subjects are given prenatal spermine (20 mg per body weight) during 26 days of pregnancy. On day 26 pregnancy is terminated and intestinal tissue sample is taken to be examined.
