The Physiology of Growth
Although clinical and experimental evidence had previously indicated that skeletal growth depended upon the pituitary gland, it was not until I92I that Evans and Long, at the University of California, demonstrated that a saline emulsion made from the anterior pituitary lobe of fresh glands of cattle contained a growth hormone. The hypophyses were thrown into 40 per cent. ethyl alcohol, agitated...
متن کاملGrowth and Physiology of Chrysanthemum morifolium Modified by the Supplementations of Various Fertilizers
To evaluate the effectiveness of various organic or inorganic fertilizers on the growth and physiology of Chrysanthemum morifolium (an important ornamental plant) the current research was conducted in a completely randomized design. Seedlings were treated with vermicompost (0 and 40% w/w of soil), nano-chelated zinc (nano-Zn) (0 and 0.1% (w/v)) or ZnSO4 (0 and 0.2% (w/v). Sprays of nano-Zn or Z...
متن کاملPreimplantation growth factor physiology.
The robust independence of preimplantation embryo development in vitro suggests that the developmental programme is autonomous. The rapid accumulation of evidence during the last decade for participation of many hormones, growth factors and their receptors in these early stages of embryogenesis has challenged this conclusion. In this review, the insulin and epidermal growth factor families, whi...
متن کاملPhysiology of Growth Hormone Secretion
Growth hormone (GH) is secreted in a pulsatile fashion from the anterior pituitary gland. The synthesis and the secretion of GH are regulated mainly by two hypothalamic neuropeptides, the growth hormone-releasing hormone (GHRH) and somatostatin. A wide variety of physiologic and hormonal factors exert an effect on GH secretion. This paper will review physiology of GH secretion and the factors t...
متن کاملPhysiology of parturition
Labor is a physiological event involving a sequential, integrated set of changes within the myometrium, deciduas, and uterine cervix that occur gradually over a period of days to weeks. Biochemical connective tissue changes in the uterine cervix appear to precede uterine contractions and cervical dilation, and all of these events usually occur before rupture of the fetal membranes. In other wor...
