2019-06-15 14:06:58 Keywords some hormonal levels, semen parameters, leptin,
Leptin concentration in seminal plasma of infertile men and relationship to semen parameters.
INTRODUCTION: Leptin is a 167 - amino acid polypeptide hormone, identified in 1994 by positional cloning in the mouse and human. This hormone is secreted by the white adipose tissue in proportion to body energy (fat) stored. Leptin functions as a satiety factor in the regulation of body weight. So far, many studies have pointed to a direct role of ... Read more

2018-12-25 21:20:25 Keywords Rheumatoid Arthritis, leptin, Disease activity (DAS28),
The relationship of serum leptin levels with disease activity in Egyptian patients with rheumatoid arthritis
Abstract Aim of the work: To investigate whether serum leptin levels are elevated in patients with rheumatoid arthritis (RA) and whether these levels correlate with disease activity. Patients and methods: A case-control study was made on 37 patients with RA and 34 healthy control subjects. The following values were assessed for each patient: erythrocyte sedimentation rate (ESR), C reactive protein ... Read more

The Histological and Immunohistochemical Study of the Leptin effect on Pars distalis of Pituitary Gland in Female Albino Rat
Background Leptin is an adipocyte-derived hormone. The plasma level of leptin is elevated in obesity and decreased in emaciation. It is involved in the neuroendocrine regulation of pituitary gland function. Aim of the work _The present work was carried out to study the histological changes in the pars distalis of the pituitary gland after an injection of leptin in female ... Read more

2018-09-27 23:12:58 Keywords leptin, puberty, femal rats,
The effect of Leptin on the Onset of Puberty in Normal Prepubertal Female Albino Rats .
Background: Many studies have focused on leptin, the product of the LEP (ob) gene, searching for a possible link between energy balance and reproduction. Objective: Investigating the effect of daily leptin injection on prepubertal female rats and the possible mechanisms by which leptin can affect reproductive axis. Materials and method: This study was applied on eighty female albino rats weaned ... Read more

2018-09-15 15:08:03 Keywords angiogenesis, leptin,
Leptin and Angiogenesis
ABSTRACT Leptin is a 16 KDa protein, consists of 167 amino acid residues. It has many functions including angiogenesis. Leptin either induces angiogenesis itself or influences the levels of other angiogenic factors. The aim of the present investigation was to study the effect of leptin on the levels of the angiogenic factors: vascular endothelial growth factor (VEGF) and thymidine phosphorylase ... Read more
