Determinación de una técnica analítica por cromatografía en capa fina para identificación de Barbitúricos y Fenotiazinas en muestra biológica (orina)
(Universidad Privada Norbert Wiener, 2020-09-23) Suarez Egusquiza, Beatriz Mery; Calle López, Mary Cruz; López Parra, Ronal Rosendo
The present research work entitled "Determination of an analytical technique by thin layer chromatography for the identification of barbiturates and phenothiazines in a biological sample (urine)", aims to determine an analytical technique by thin layer chromatography (TLC) for the identification of barbiturates and phenothiazines. The methodology used was analytical, descriptive and observational, using 30 biological urine fluids as samples. The results report that the phenothiazine was identified using the iodine platinate and Dragendorff revealing reagents, giving a violet-blue color, accentuated by sprinkling 10% hydrochloric acid, which indicates a positive reaction. Likewise, the revealing reagents formaldehyde plus sulfuric acid and the mercury revealing reagent gave a positive result for barbiturates, through the appearance of a whitish color. Conclusions: An analytical technique using thin layer chromatography was identified to identify phenothiazines and barbiturates in biological urine samples.

(Universidad Privada Norbert Wiener, 2021-05-17) Bautista Huamaní, Alexi Arthur; Damian Inga, Elvis Cesar; López Parra, Ronal Rosendo
The research, titled "Rate of Ethanol Elimination in Biological Samples (Blood) in Adults from Mangomarca – San Juan de Lurigancho, May 2018," had the objective of determining the rate of ethanol elimination in biological samples (blood). Methodology: A descriptive, experimental, and cross-sectional study was conducted. Blood samples were collected in heparin vials from 36 adults from Mangomarca, SJL. The study began with the ingestion of 1260 mL of beer over 20 minutes. After ingestion was completed, samples were taken every 30, 45, 60, and 75 minutes. The method used was the modified Shefftell and UV-Vis Spectrophotometry. Results: Variability was found between genders and among age groups. The average elimination rate for females was 0.186 g/L/hour, while for males it was 0.159 g/L/hour. The 18-30 year age group reported an elimination rate of 0.169 g/L/hour, the 31-50 year age group reported 0.178 g/L/hour, and the over-50 age group had an elimination rate of 0.167 g/L/hour. Conclusions: There is variability in the rate of ethanol elimination in blood biological samples. The average ethyl alcohol elimination rate in the study population was 0.172 g/L. For women, it was 0.186 g/L, and for men, it was 0.159 g/L. The age group with the highest elimination rate was 31–50 years old.

Estudio del extracto etanólico de los rizomas de Curcuma longa L. “Cúrcuma” y su actividad antioxidante
(Universidad Privada Norbert Wiener, 2019-03-08) Aliaga Palomares, Ana María; Muñoz Suárez, Liliana Sofía; López Parra, Ronal Rosendo
Objective: To determine the phytoconstituents present in the rhizome of Curcuma longa L. “turmeric” and its antioxidant activity. Materials and Methods: The study was quasi-experimental, descriptive, and cross-sectional. The study species was collected in the district of Kimbiri, Province of La Convención, Cusco. An ethanolic extraction of the dried turmeric rhizomes was carried out in order to perform the qualitative phytochemical analysis, following the methodology proposed by Olga Lock de Ugaz, to determine the phytoconstituents. Dilutions of the dry extract were prepared at concentrations of 5%, 10%, and 20%. Antioxidant activity was evaluated using the DPPH assay (1,1-diphenyl-2-picrylhydrazyl), and the absorption band was measured at 517 nm with a UV-Visible spectrophotometer. These results were analyzed with the statistical software IBM SPSS Statistics version 24.0 and Microsoft Excel 2016. Results: The presence of secondary metabolites such as phenolic compounds, flavonoids, quinones, and coumarins was determined. The antioxidant activity results are presented as the mean inhibition percentage of the ethanolic extract at 5%, 10%, and 20%, which were 81.552%, 82.077%, and 83.742%, respectively, compared with the standard sample of Vitamin C, which showed means corresponding to 5%, 10%, and 20% of 96.258%, 93.313%, and 84.110%, respectively. Conclusion: It was determined that the ethanolic extract of the rhizomes of Curcuma longa L. “turmeric” exhibits antioxidant activity comparable to that of Vitamin C and may be considered a source of natural antioxidants. This activity is attributed to the presence of phenolic compounds and flavonoids.

The main reasons for self-medication were headache (19.10%, 34), high blood pressure problems (16.85%, 30), and urinary tract infection issues (14.61%). The pharmacological groups most frequently self-administered were analgesics (24.16%, 43), anti-inflammatories (11.80%, 21), and antibiotics (10.06%, 18). The last instance of self-medication was often based on the recommendation of the pharmacy, accounting for 43.27% (77). Conclusion: The study found a high level of self-medication among the population of Néstor Gambeta Baja – Callao, with lack of time being a key contributing factor. It is recommended to promote educational talks to the population to encourage proper medication use and reduce the risks associated with consuming medications without a prescription.
