Comparison Between Clinical Outcome of Intralesional Human Placental Extract Alone and Topical Application of Placental Extract Gel After Fibrotomy in Oral Submucous Fibrosis.

Oral submucous fibrosis (OSMF) is a premalignant condition prevalent in our country. Juxtaepithelial inflammation with progressive hyalinization of the lamina propria results in stiffness and fibrosis of the oral mucosa, characterised by trismus, ankyloglossia, and a burning sensation. Various methods of treatment have been tried in these cases, which include placental extract injections and the cutting of fibrous bands. In this study, we aim to compare the outcome of intra-lesional placental extract injection with fibrotomy and placental extract gel application in OSMF. This prospective interventional study included 58 patients clinically diagnosed with OSMF grades II and III at a rural tertiary care hospital between January 2021 and August 2022. The patients were randomised into two groups: group I received 1 ml of intra-lesional human placental extract injection in the submucosal plane of the buccal mucosa and retro-molar trigone (RMT) once a week for five consecutive weeks, and group II was subjected to a transverse division of fibrotic bands in the submucosal plane under general anaesthesia. The surgical wound was left open, and swabs soaked in human-purified placental extract gel were placed in the wound for two hours twice daily until the surgical wound was epithelialized and healed. The patients in both groups I and II were advised to do jaw opening exercises, and weekly follow-up was done. Findings with regard to maximum mouth opening, colour of mucosa, and burning sensation in the oral cavity based on a Likert scale were documented. At the end of five months, the pre-treatment and post-treatment results documented were compared. All patients were between 20 and 60 years of age and were addicted to chewing areca nuts with tobacco. Bilateral involvement was present in all patients, with extension into the RMTand soft palate seen in 31%. Improvement in mouth opening was between 4 mm and 6 mm in group II, and relief of burning sensation and mucosal colour was better in group I. Intra-lesional placental extract injections help in the improvement of the mucosa and relief from the burning sensation. Fibrotomy with placental extract gel application is better at relieving trismus in OSMF. Aggressive mouth-opening exercises may improve mouth opening following the above procedures.

The Use of a Natural Polysaccharide as a Solidifying Agent and Color-Fixing Agent on Modern Paper and Historical Materials

This article presents results on the use of a new material as a solidifying agent and/or color-fixing agent. A special polysaccharide material extracted from the prickly pear cactus (Opuntia ficus indica) was tested on historical materials and modern papers. An old book from the 18th century was chosen as historical material. From the mentioned book 42 pages were taken, on which a conservation and restoration pretreatment was performed before applying the polysaccharide material: sampling, fiber analysis, dry cleaning, ink solubility, pH test, thickness measurement and wet cleaning. The paper sheets provided for the test were divided into 4 groups, 3 of which were treated with gel and one left untreated as a reference. The division into groups is not only due to the different method of application, but also due to the process of gel extraction. The effect of the treatment was analyzed using FTIR-ATR. To test the mucilage as color-fixing agent 2 samples were prepared using watercolor papers colored with 6 different watercolors applied to 2.5 cm2 samples for each color in two rows of different intensity. One of the 2 samples was treated with gel, but both were immersed for 3 times in a water-ethanol solution for approximately 20 min as is standard practice in conservation and restoration. After washing, both specimens were subjected to colorimetric analysis to assess their differences. The results provided satisfactory evidence for the protection of paints sensitive to aqueous treatments and suggest the use of mucilage as a new material in cleaning method for water-soluble media.

Polymorphism of the ApoE gene as a risk factor of obesity in workers exposed to occupational hazards at ferrous metallurgy enterprises

Obesity contributes to the development of severe concomitant diseases and substantially degrades the quality of life. This pathological condition is caused by multiple risk factors including hazardous workplace exposures and genetic predisposition. The ApoE gene participates in regulation of lipid metabolism. Its most significant polymorphisms are rs429358 and rs7412 with the resulting е2, е3 and е4 alleles. This study did not consider effects of electromagnetic fields generated by office electrical equipment or the lifestyle of the subjects. The sample included people with a large age difference due to the rarity of the apolipoprotein е2 and е4 alleles. The sample was not standardized by age and years of work experience. The aim of this study was to investigate associations between the ApoE gene polymorphisms and body mass index in workers employed at a metallurgic plant. We examined 328 male office workers and workers of a converter workshop. The body mass index (BMI) was calculated based on the results of instrumental measurements of weight and height using the conventional formula. DNA was isolated from peripheral blood using the LumiPure DNA gel extraction kit, and polymorphisms were determined using amplification by Calero et al with modifications and horizontal agarose gel electrophoresis. The data were analyzed using the Kruskal – Wallis test. Statistically significant differences were established in the blue-collar workers. The highest mean BMI value was established in the e2 allele carriers. We found that people with the e2 allele in their genotype were more prone to obesity. We also assume a potential association between the unsafe work environment and a more pronounced manifestation of the phenotype. These findings can be used for identifying individuals at risk and taking timely preventive measures.

Comparison of healing effects of aloe vera gel and aloe vera leaf pulp extract on burn-wound rats

Aloe Vera has anti-inflammatory, anti-oxidant, anti-viral, and anti-microbial properties. It has been demonstrated that Aloe Vera use could accelerate healing of burn injuries in rats. The current study evaluates the effects of Aloe Vera gel and Aloe Vera leaf pulp extract (LPE) alone and together with silver sulfadiazine on third degree burn wound injuries in rats. In an experimental study, 70 male Wistar rats weighing 200–250 g were divided into 7 groups to receive topical placebo, silver sulfadiazine, Aloe Vera gel, Aloe Vera LPE and their combination. Treatment results were evaluated according to wound healing on days 3, 10, and 21 and according to pathologic findings on day 21. Wound size differed significantly between groups on day 3 (p= 0.001), day 10 (p= 0.001), and day 21 (p= 0.001). The study's findings indicate that Aloe Vera gel alone, compared to LPE, and the combination of Aloe Vera gel or LPE with silver sulfadiazine had a more significant reduction in wound size. The combined treatment of Aloe Vera LPE and silver sulfadiazine has shown several advantages, including enhanced epithelialization and reduced cell infiltration, granulation tissue formation, and vascularization in the treatment of burns. However, additional research is necessary to determine the most effective treatment for third-degree burns.
