Higher cyclorrhaphan flies including Drosophila develop a single extraembryonic epithelium (amnioserosa), which closes the germband dorsally. In most other insects two extraembryonic epithelia, serosa and amnion, line the inner eggshell and the ventral germband, respectively. How the two extraembryonic epithelia evolved into one is unclear. Recent studies have shown that, in the flour beetle Tr...

BACKGROUND Different methods for dressing of donor site of skin graft in burn patients have similarly pain, limitation of mobility of donor site and local complications such as infection and scar. Amniotic membrane has used for improvement of healing in some wounds. Accordingly in this study amnion was used as biologic dressing for donor site of skin graft to evaluate it’s efficacy in improveme...

In an earlier report (5), it was shown that under specified conditions the application of high hydro-static pressure to FL amnion ceils resulted in an increase of measurable endogenous adenine nucleotides , although the more slowly metabolizing primary amnion cells showed no such increase 408 BRIEF NOTES

OBJECTIVE Prostaglandins (PGs) are key regulators of cervical dilatation and membrane breakdown at the onset of labor. PG synthase and receptor expression has been previously documented in uterine tissues; however, mechanisms governing the changes occurring in the cervix and amnion are less well established. The aim of the current study was to determine the level of expression of PG synthetic e...

Human amnion tissue is readily available to most laboratories as a source of cells for tissue culture studies. It has proved to be a useful tool in the field of virus research, and it offers impor tant potentials in the field of cancer research as a source of normal human cells easily obtained in primary cultivation. Many investigators have been concerned with the problem of malignant propertie...

Mouse polyclonal antibodies have been raised against two human proteins (IEF [isoelectric focusing] 31, Mr = 50,000; IEF 46, Mr = 43,500) that have previously been shown to be present in HeLa cytoskeletons enriched in intermediate-sized filaments. Immunoprecipitation studies show that both proteins share common antigenic determinants with each other and with the putative human keratins IEF 36 a...

BACKGROUND Facial burns are common and have a significant impact on patient function and psychosocial well being. Human amnion has been used for many years as a temporary biological wound dressing in the management of partial thickness burns. The observed advantages of human amnion treatment include pain relief, ease of use, prevention of infection and acceleration of wound healing. OBJECTIVE...

Introduction Amnion rupture in early pregnancy results in severe anomalies such as anencephaly, encephalocoele, exencephaly, acrania, facial clefts and absence of limbs (1,2). Most affected fetuses abort in the second trimester, are stillborn or die soon after birth (1,3).We report an infant with amnion rupture sequence, who survived for 9 weeks after birth. A Medline search failed to reveal do...
