Abstract

Polycystic Ovary Syndrome (PCOS), a major endocrine disorder, affects the reproductive function of a woman, along with an association with metabolic conditions like insulin resistance and inflammation. The inflammatory nature of PCOS is much debated over, owing to numerous cases of elevation in cytokine levels. Studies have shown the beneficiary effect of Gamma-Linolenic acid (GLA) in reducing inflammation related to many conditions such as atopic dermatitis, rheumatoid arthritis, arterial disease, obesity, and even PCOS. The study aims at assessing the expression of inflammatory cytokines in the ovary and Peri-ovarian adipose tissue (POAT) of the Dehydroepiandrosterone (DHEA) induced PCOS rat model. Further, this study also evaluates the effect of γ-linolenic Acid (GLA) on these cytokines in POAT. Female Wistar rats were subcutaneously injected with 60 mg/kg DHEA daily for 28 days. These PCOS-induced rats were then orally administered with 50 mg/kg GLA for 14 days. The gene expression of cytokines was assessed by Real Time-PCR. The study showed an increase in the expression of cytokines in the ovary and POAT of the DHEA group. This suggests the role of ovarian adipose in adding to the pro-inflammatory state of PCOS. Moreover, ...Continue Reading

Atopic Dermatitis

Atopic dermatitis is a chronic inflammatory genetically determined disease of the skin marked by increased ability to form reagin (IgE), with increased susceptibility to allergic rhinitis and asthma, and hereditary disposition to a lowered threshold for pruritus.
