![]() ![]() Questions concerning how a variety of wounds heal and effective medical support of the healing process remain open to debate and of immediate concern. The proven efficacy of developed polymeric compounds demonstrates the feasibility of further studies in clinical practice. DHCB did not affect the rate of healing for acute wounds without ischemia during the first week. Invasive drugs and DCh slowed the regeneration process. The treatments in the PCCD and MSC groups were more effective than in the DHCB and DCh groups. The most effective remedy was combination PCCD + MSC. After 14 days, we evaluated the state and size of the wounds, studied the level of microcirculation, performed a histological study, and identified and counted the different types of cells. Eight groups were studied: Control_0-intact wounds Control_ss-0.9% NaCl injections MSC injections Control_msc-intact wounds on the opposite side of the body from the MSC group external application of the PCCD external application of a combination of the drugs PCCD + MSC DCh –ointment Dioxomethyltetrahydropyrimidine + Chloramphenicol and DHCB-injections of a deproteinized hemoderivative of calf blood. Two wounds were made on the backs of each of 112 Wistar rats, removing the skin. In the some of the frequency distribution curves observed fractures and curvature that is due to contamination and magma mixing and fractionation process.We studied the efficacy of using mesenchymal stem cells (MSC) and a polymeric compound (based on chitosan and cellulose with integrated cerium dioxide nanoparticles (PCCD)) in wound healing, and to compare the effects with various invasive and external drugs used for the same purpose. ![]() So crystal presence in the granodiorite and granites are larger than crystals of quartz monzodiorites and it is compatible with petrographic observations and indicates the important of different physical conditions prevailing in the magma solidification. Also nucleation rate in quartz monzodiorite is maximum and granites and granodiorite have minimum amounts. According to growth rate (10 -10 mm/s) and CSD graphs slope (-3.93 -6.88), samples have grown in different time ranges, and growth time in the granodiorite and granites is more than quartz monzodiorite as growth time procure 54.29 to 81.93 years in granite rocks and 46.08 years in quartz monzodiorite rocks. The calculated volumetric proportion indicates that percent of these minerals vary from 10.95 (in quartz monzodiorite) to 39.2 (in granites). ![]() In order to determine volometric proportion, growth time and nucleation rate of feldspar crystals and magma crystallization rate, feldspar crystals from 8 samples of granite, granodiorite and quartz monzodiorite rocks have been studied to quantitative analysis by JMicrovision and CSD Corrections softwares and then the results of the analysis of various samples were compared together. Crystal size distribution (CSD) studies can reveal magmatic processes. These rocks have granular texture and occasionally granophyric, pertite and poicelitic textures. The Byarjomand Batholith with Pre-cambrian age in the north Semnan, north-central Iran, consists of granite, granodiorite, quartz monzodiorite and gabbrodiorite. ![]()
