Growth of Fibroblasts and Hydrogen Ion Concentration of the Medium

Effect of Low–Level Helium-Neon Laser Irradiation on the Release of Interleukin 6 and Basic Fibroblast Growth Factor from Cultured Human Fibroblasts in High Glucose Medium

Purpose: Low level laser therapy is suggested as a new therapeutic method in diabetic wound healing. This survey aimed to evaluate the effects of low level laser on human fibroblasts cultured in high glucose cultures. Materials and Methods: The human skin fibroblasts were cultured under standard condition. The cells were cultured in high glucose culture medium (15mM/L) for a week and two weeks ...

In vitro Co-Culture of Human Skin Keratinocytes and Fibroblasts on a Biocompatible and Biodegradable Scaffold

Background: Extensive full-thickness burns require replacement of both epidermis and dermis. In designing skin replacements, the goal has been to re-create this model and make a product which has both essential components. Methods: In the present study, we developed procedures for establishing confluent, stratified layers of cultured human keratinocytes on the surface of modified collagen-chito...

Growth response and ion distribution of two canola varieties to different potassium to sodium ratios

Rapeseed (Brassica napus L.) is a crop relatively tolerant to salt. The effect of different ratios of NaCl/KCl was studied in two cultivars (Hyola308 and Kristina) of Rapeseed in 2002. Canola seedlings were grown in Hoagland’s solutions, which were salinized by different ratios of NaCl/KCl. The treatments or KCl:NaCl ratios were 0:0 (control);10:10; 20:0 (Total Added Salt or TAS=20 mol.m-3), 0:...

Adsorption of Cr(III) and Mg(II) from Hydrogen Peroxide Aqueous Solution by Amberlite IR-120 Synthetic Resin

In concentration of hydrogen peroxide, first, the solution should be quite pure, and then, it concentrate with methods such as vacuum distillation and cooling crystallization, because impurities in the hydrogen peroxide solution in high concentrations are causing decomposition of this substance; that is very dangerous. The purpose of this article is separation of chromium and magne...
