Background & Objective:  Toxico-pathological effects of herbal plants have always been a major concern, but little information is provided on the toxico-pathological effects of origanum on the fetus. Due to ethical rules and regulations, no drug experiment on the human fetus is permitted; hence, the chick embryo model is used as an ideal opportunity to study the adverse effects of drugs. This ...

introduction: depending on mode, intensity and length of application, and stage of development, the low-frequency electromagnetic fields (lfes) can induce a wide variety of biological effects in organisms. the chick limb bud is a powerful experimental system for study pattern formation in vertebrate embryo. the aim of this study was to examine the effects of an application lfes (50hz, 50g) on c...

CD9 is a tetra-membrane-spanning glycoprotein involved in cell adhesion, migration, growth signaling and tumor cell metastasis. In this study a CD9 cDNA clone has been isolated from chick cDNA library. The chick CD9 clone contains an open reading frame of 224 amino acids. The deduced amino acid sequence from chick CD9 shows 63.3% identity with the human counterpart. Human and monkey CD9 upregul...

The developmental stages [4] of the chick [5] embryo were examined by Viktor Hamburger [6] and Howard L. Hamilton [7] in ?A Series of Normal Stages in the Development of the Chick Embryo,? published in the Journal of Morphology [8] in 1951. These stages were published to standardize the development of the chick [5] based on varying laboratory conditions and genetic differences. The stages Hambu...

Hole is a novel gene product isolated from a chick heart subtractive hybridization. Hole is a six-transmembrane protein (predicted size 311 and 317 amino acids in chick and mouse) expressed in the cardiac crescent and later in the myocardium of the developing chick heart, as well as in the fusing neural tube and ganglia. Mouse hole is not expressed in the developing heart, although it does shar...

Quantitative analysis of production through evaluation of inputs consumption quantity is of main principles in agricultural policies, which is followed by increasing in production through optimal use of resources. This study has been conducted to estimate different types of production functions in mechanized farms of broiler chicks located in Gorgan city. Cross-section survey data were gathered...

There is nothing quite so helpless in this world as a baby broiler chick which has been snatched from the warmth of its surrogated mother, carted umpteen kilometers in a box dumped unceremoniously in a broiler shed and then told to get on with the job of making the boss a wealthy man. Yet within the space of 14 days, that same chick, under optimum conditions, will have increased its day-old bod...

Chick globin synthesis was studied in heterokaryons formed between chick erythrocytes and human K562 erythroleukemia cells or rat L6J1 myoblasts. It was found that chick globin synthesis was activated after fusion of definitive (17 to 19-day) chick erythrocytes obtained from 17 to 19-day embryos with K562 cells. Chick globins appeared to be of the adult alpha A, alpha D and beta types, whereas ...

The present study aims to examine the cost and returns of Chick pea. was conducted in Bemetara district Chhattisgarh state. From two blocks namely Saja were selected from bemetara block nine villages six fifteen chick-pea growing farmers each village for investigation study. primary data collected 225 producers through personal interview by survey method. finding revealed that cultivation per h...

The purpose of this experimental study was to evaluate the effect of chicken amniotic fluid (AF) on a cross section of rat sciatic nerves. Thirty adult male Sprague-Dawley rats weighing 275 to 300 g, were randomized into three groups treated with (1) amniotic fluid or AF (n=10), (2) normal saline or NS (n=10), and (3) sham surgery (n=10). The AF was aspirated from the amniotic cavity of incubat...
