â¢ spaces in between cells allow fluid from vessels in the dermis to. nourish the cells (epidermis is avascular!) â¢ Langerhans cells (involved in the immune system) found here. stratum germinativum (basalis) â¢ contains stem cells from which new keratinocytes arise by mitosis. a) these cells are relatively small, cuboidal to low columnar. b) look for mitotic cells with basophilic appearance. â¢ melanocytes are dendritic cells that synthesize melanin.
Fish oil EPA and DHA are both polyunsaturated fatty acids, and each unsaturated bond (double bond) can possibly be oxidized; this would convert the lipid itself into an oxidant capable of producting other oxidants and is a phenomena common to any unsaturated fatty acid including arachidonic acid.
For high triglycerides: 1-15 grams of fish oil daily for up to 6 months, or fish oil providing 1.45 to 2.70 grams of EPA and 1.05 to 1.80 grams of DHA daily for 2 to 12 weeks, has been used. For heart disease: Fish oil containing 0.6-10 grams of DHA and/or EPA daily has been taken for one month to 9 years.
