Phytochemical investigations of Campsis radicans L.

Petroleum ether, dichloromethane and ethyl acetate soluble fractions were obtained through partitioning the crude methanolic extract of the leaves of Campsis radicans L. (Family. Bignoniaceae) followed by the chromatographic separation of secondary metabolites from them. A total of five triterpene compounds i.e., corosolic acid methyl ester (1), β-amyrin (2), arjunolic acid (3), maslinic acid (4) and 28-O-[β-D-glucopyranosyl-(1→6)-β-D-glucopyranosyl]-2α,3α,19α-trihydroxy-12-en-28-ursolic acid (5) were isolated from the dichloromethane fractions and their structures were characterized by 1H NMR spectroscopy and compared the NMR data with published values

Evaluation of analgesic, antioxidant and cytotoxic activities of ethanol extract of Clerodendrum viscosum Vent

Clerodendrum viscosum Vent. is a very common plant in Bangladesh which is locally familiar as “Bhat” or “Ghetu”. Here, the ethanol extract of whole plant part of C. viscosum and its various solvent (petroleum-ether, chloroform and ethyl acetate) fractions were subjected for the appraisal of analgesic, antioxidant and cytotoxic activities. Analgesic activity was tested by acetic acid-induced writhing model in Swiss albino mice. All the plant samples at the oral doses of 100- and 200 mg/kg body weight were found to exhibit significant (p<0.05) pain reducing activity in test animals. Highest inhibition of writhing was 62.38% by the ethyl acetate soluble fraction at dose of 200 mg/kg body weight while the standard drug diclofenac sodium (50 mg/kg) produces 76.14% reduction of abdominal writhing. DPPH (2,2-diphenyl-1-picrylhydrazyl) free radical quenching assay was employed to determine the antioxidant potential of the plant samples while cytotoxic activity was checked by brine shrimp lethality bioassay. In DPPH radical scavenging assay, the plant samples showed prominent antioxidant activity. Among all, the ethyl acetate fraction showed maximum antioxidant potential with IC50 value of 28.02±0.53 μg/ml. In cytotoxic assay, the petroleum-ether fraction demonstrated strong cytotoxicity with LC50 value of 1.42±1.12 μg/ml. In summary, C. viscosum extracts possess significant analgesic, antioxidant and cytotoxic activities which rationalize its traditional use in folk medicine

Actividad antimicrobiana preliminar y citotoxicidad de extractos de hojas de Mussaenda roxburghii Hook. f.

En el presente estudio, la actividad antimicrobiana in vitro, junto con la concentración inhibitoria mínima (CIM) y la concentración bactericida mínima  (CBM), de diferentes extractos de las hojas de Mussaenda roxburghii Hook. f. fueron evaluadas contra 13 microorganismos patógenos. El extracto metanólico  y sus fracciones solubles en tetracloruro de carbono y cloroformo mostraron la actividad antimicrobiana más alta. La fracción soluble en cloroformo mostró la  zona de inhibición máxima de 16,0 mm en contra de Bacillus megaterium, con valores de MIC y CBM de 7,81 g/ml y 250 mg/ml, respectivamente.  Ciprofloxacina (30 μg/disco) se usó como agente antimicrobiano estándar. En el bioensayo de letalidad con Artemia salina, tanto el petróleo-éter y  tetracloruro de carbono como la fracción soluble del extracto de metanol crudo demostraron una fuerte actividad citotóxica con valores de LC50 de 0,52 y 0,62  mg/ml, respectivamente, en comparación con la de 0,451 mg/ml de sulfato de vincristina utilizado como estándar

Study on clinical features and factors associated with thickness of chronic subdural hematoma in adult

Patients with chronic subdural hematoma encounter certain difficulties in diagnosis, especially in elderly, due to the characteristically non-specific symptoms and signs. Early diagnosis and proper operative treatment, on the other hand, results in complete recovery in most of the cases. In this study, the clinical features and factors of 31 patients with chronic subdural hematoma, associated with the thickness of chronic subdural hematoma were analyzed. The mean age was 62 ± 13.9 years. The maximum hematoma thickness in the axial CT scan was 25 mm. The thickness of hematoma obtained from axial plain CT had a positive relationship with the patient’s age where r=0.895 and p<0.001 signifies that the thickness of hematoma increased with the increasing age. But the hematoma thickness was not related to co-morbidity such as diabetes mellitus, hypertension and ischemic heart disease. The presentation of the patient with higher hematoma thickness with hemiparesis was statistically significant and with lower thickness with headache and vomiting

Stealth cranioplasty in symptomatic adult chiari 1 malformations: Experience at Bangabandhu Sheikh Mujib Medical University

Background: The surgical management of symptomatic adult Chiari malformation type 1 (CM1) with or without syringomyelia (SM) continues to be a dilemma considering the outcomes. Objectives: The study aimed to compare the clinical outcomes between stealth cranioplasty (SC) and one of the most commonly practiced standard procedures, posterior fossa decompression with duraplasty (PFDD). Clinical outcomes between SC and another procedure posterior fossa decompression (PFD) were also compared. Methods: This comparative cross-sectional study was carried out on 37 males and 16 females symptomatic adult CM1 patients, ranging from 18 to 47 years of age from June 2019 to May 2021. Clinical outcomes were assessed, compared, and analyzed in terms of changes in clinical symptoms and signs, chicago chiari outcome scale (CCOS) score, and occurrence of complications.  Results: Of the 53 patients, 23, 19 and 11 underwent SC, PFDD, and PFD, respectively. There were no significant post-operative changes in symptoms and signs among groups except changes in limb weakness between SC and PFDD (P=0.004). Considering average CCOS score, SC performed better only than PFDD (P=0.003), while category-wise SC was better than both PFDD (P=0.004) and PFD (P=0.010). Considering complications, the PFDD group had a significantly higher rate of complications than the SC group (P=0.001), while there was no significant difference in the rate of complications between the PFD and SC groups. Conclusion: SC was found to have better clinical outcomes than the PFDD and PFD groups as a technique. Bangabandhu Sheikh Mujib Medical University Journal 2023;16(1): 08-1
