Inflammatory diseases being one of the back bending global burden are alarming the world. Established anti-inflammatory drugs exert side-effects, demanding for the development of alternative drugs, likely from natural source because of their diverse chemical nature. The anti-inflammatory activity of aerial part methanol extract of Elsholtzia densa collected from the natural forest of Naranag area of Kashmir valley was evaluated both in vitro and in vivo model systems using Macrophages RAW 264.7 cells and acute (carrageenan and histamine-induced rat paw edema) and chronic model (formaldehyde induced arthritis) respectively. The EDM extract exhibited a significant decline in the paw volume being at par with the standard drug Diclofenac (10 mg/kg) as compared with the control group. The reduction was observed in dose dependent manner with 300 mg/kg resulting in 27.27% and 100 mg/kg in 16.88% inhibition at 3rd h. A statistically significant (p < 0.05) decline in the secretion of serum pro-inflammatory cytokines like TNF-α, IL-1 β and IL-6 was found with 80.93%, 75.33% and 67.09%, and 83.25%, 62.11% and 66.69% in EDM-300 as compared with the carrageenan and histamine group respectively. The pro-inflammatory cytokines levels showed clampdown in LPS stimulated RAW264.7 by the extract treatments. The LC–MS data revealed the presence of Quercetin 3-glycosides, Apigenin 7-(2″-acetyl-6″-methylglucuronide) and betulinic acid as major compounds present in EDM extract. Results obtained from in vivo experiments demonstrate that oral administration of EDM extract significantly attenuated inflammation in carrageenan and histamine-induced paw edema, and improved chronic models (formaldehyde induced arthritis).

Associations of GSTT1, GSTM1 and CYP1A1 gene variants with risk of developing oral cancer were evaluated in this study. A case-control study was conducted in Pashtun population of Khyber Pakhtunkhwa province of Pakistan in which 200 hospital based oral cancer cases and 151 population based healthy controls exposed to similar environmental conditions were included. Sociodemographic data were obtained and blood samples were collected with informed consent for analysis. GSTM1 and GSTT1 were analysed through conventional PCR method while specific RT-PCR method was used to detect CYP1A1 polymorphisms. Results were analyzed for conditional logistic regression model by SPSS version 20. The study shows that patients with either GSTM1 or GSTT1 null genotypes have significantly higher risk of oral cancer (adjusted odds (OR): (3.019 (1.861-4.898) and 3.011(1.865-4.862), respectively), which further increased when either one or both null genes were present in combination (adjusted odds (OR): (3.627 (1.981-6.642 and 9.261 (4.495-19.079), respectively). CYP1A1 rs4646903 gene variants individually showed weak association OR: 1.121 (0.717-1.752); however, in the presence of GSTM1 and/or GSTT1 null genotypes further increasing the association (adjusted odds (ORs): 4.576 (2.038-10.273), 5.593 (2.530-12.362) and 16.10 (3.854-67.260 for GSTM/GSTT null and CYP1A1 wild type, GSTM/GSTT either null and CYP1A1 variant alleles, and all 3 gene polymorphisms combinations, respectively). Our findings suggest that presence of GSTM1 and/or GSTT1 null genotypes along with variant alleles of CYP1A1 may be the risk alleles for oral cancer susceptibility in Pashtun population.
