Explore the antiproliferative phytocompounds from ethanolic extracts of Citrus paradisi against liver cancer cell line by chemical analysis using TLC and FT-IR spectroscopy

Abstract The aim of the present study was to evaluate the in vitro antiproliferative activity of ethanolic extract of leaves and fruits Citrus paradisi plant on HepG-2 liver cell lines by MTT (3-(4, 5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-terazolium bromide) assay and to isolate and characterize the antiproliferative compounds by TLC (Thin layer chromatography) and FT-IR (Fourier transforms Infrared) spectroscopy. Qualitative phytochemical screening tests were performed to detect phytochemicals compounds from the crude extracts. Antioxidant activity of the plant extracts were characterized by using DPPH (2,2-Diphenyl-1-picrylhydrazyl) free radical scavenging method. The results showed that antioxidant activity using DPPH were found to be increased in a concentration dependent manner and decreased cell viability and cell growth inhibition in a dose dependent manner. The findings from this study indicated that fruit extract exhibited good antiproliferation and antioxidant potential. The seven functional groups of phytocompounds such as carboxylic acid, amine salt, aromatic compounds, cyclic alkene, aldehyde, fluoro compounds and alkene were detected by FT-IR which indicated that fruit extracts of Citrus paradisi possessed vast potential as a medicinal drug especially in liver cancer treatment.

Resumo O objetivo do presente estudo foi avaliar a atividade antiproliferativa in vitro do extrato etanólico de folhas e frutos da planta Citrus paradisi em linhagens de células hepáticas HepG-2 por MTT (3- (4, 5-dimetil-2-tiazolil) -2, Ensaio de brometo de 5-difenil-2H-terazólio) e isolar e caracterizar os compostos antiproliferativos por espectroscopia de TLC (cromatografia de camada fina) e FT-IR (infravermelho com transformadas de Fourier). Testes qualitativos de triagem fitoquímica foram realizados para detectar compostos fitoquímicos nos extratos brutos. A atividade antioxidante dos extratos vegetais foi caracterizada pelo método de eliminação de radicais livres DPPH (2,2-difenil-1-picrilhidrazil). Os resultados mostraram que a atividade antioxidante usando DPPH aumentou de uma maneira dependente da concentração e diminuiu a viabilidade celular e a inibição do crescimento celular de uma maneira dependente da dose. Os resultados deste estudo indicaram que o extrato de fruta exibiu bom potencial antiproliferação e antioxidante. Os sete grupos funcionais de fitocompostos, como ácido carboxílico, sal de amina, compostos aromáticos, alceno cíclico, aldeído, compostos de flúor e alceno, foram detectados por FT-IR, o que indicou que extratos de frutas de Citrus paradisi possuíam vasto potencial como medicamento, especialmente no tratamento de câncer do fígado.

​A Retrospective Comparison of Mortality in Hematological versus Non-Hematological Malignancies in Cancer Intensive

Objective: The objective of this study was to study the demographic data and clinical outcome of cancer patient admitted inintensive care unit (ICU).Materials and Methods: Data of cancer patients admitted in ICU of tertiary care hospital between August 2017 and September2018 were reviewed retrospectively.Results: During the study period, 441 cancer patients were admitted in ICU. Majority of patients were male (58.27%). The mostcommon reason for ICU referral was respiratory problem (31.75%) followed by cardiovascular (26%). Lung carcinoma wasthe most common among solid malignancy, whereas lymphoma was the most common hematological malignancy. Patientswith hematological malignancy were relatively younger (55 years vs. 63 years). Patients who required inotropes/vasopressorsor mechanical ventilation had poor prognosis than the others. The mortality rate was higher in patient with hematologicalmalignancy than solid malignancy patients.Conclusion: The demand for intensive care for critically ill cancer is increasing, and considering the improvement in prognosiscancer patients should not be denied ICU care merely on the basis of a patient suffering from cancer. Data suggest that admittingselected patient with cancer to ICU is justifiable, but mere admitting patents for end of life care is not recommended.

Multiple antibiotic resistance among gram negative bacteria isolated from poultry.

Gram negative bacteria, including species of Salmonella, Escherichia, Pseudomonas and Klebsiella, isolated from poultry, were screened for their resistance to the commonly used antibiotics: ampicillin, chloramphenicol, gentamycin, kanamycin, neomycin, polymyxin B, streptomycin and tetracycline. Of the 500 bacteria screened, 351 were found to be resistant to one or more antibiotics at the level of 50 micrograms/ml. Various patterns of antibiotic resistance observed during these studies have been reported.
