PURPOSE: Cigarette smoking is a major risk factor in periodontal diseases. The pathogenesis of periodontal diseases may be affected by alterations of the inflammatory response by smoke. Nitric oxide (NO) is a gaseous, colorless, highly reactive, short-lived free radical with a pivotal role in the regulation of various physiological and pathological mechanisms in the body. It is important in host defense and homeostasis, on the one hand, whereas, on the other hand, it modulates the inflammatory response in periodontitis, leading to harmful effects. The aim of this study was to assess the levels of NO in both the serum and saliva of smokers and nonsmokers having chronic periodontitis and to compare them with periodontally healthy controls. METHODS: Sixty subjects participated in the study and were divided into three groups: group I, healthy nonsmoking subjects; group II, nonsmoking patients with chronic periodontitis; group III, smoking patients with chronic periodontitis. Each group consisted of twenty subjects. The biochemical estimation of NO in the collected serum and in the saliva was performed using the Griess colorimetric reaction. RESULTS: The results showed that the mean value of the salivary and serum NO was greater in group II than in group I, and also greater in group III than in group II. CONCLUSIONS: NO appears to play an important and rather complex role in the immuno-inflammatory process and in the remodeling and maintenance of osseous structures. It is therefore logical that modulation of this mediator has potential for the treatment of a number of inflammatory conditions including periodontal disease.

OBJECTIVEKanchnar guggulu is a compound Ayurvedic formulation used in clinical practice for the treatment of benign and malignant tumors. The present study investigates its cytotoxic and antiproliferative activities.
METHODSThe hydro-alcoholic (50%) extract of kanchnar guggulu was prepared. Its antimitotic activity was assessed in an Allium cepa assay, while its antiproliferative effects were studied in a yeast proliferation model. Methotrexate was used as a standard anticancer agent.
RESULTSIn the Allium assay, all concentrations of the extract (1, 2 and 3 mg/mL) and methotrexate (0.02 mg/mL) significantly inhibited the division of A. cepa root cells, decreasing root growth and mitotic index compared to control; this effect was concentration-dependent for kanchnar guggulu extract. In the antiproliferative studies, treatment with the hydro-alcoholic extract of kanchnar guggulu (1, 5 and 10 mg/mL) and methotrexate (0.025, 0.05 and 0.1 mg/mL) resulted in marked reduction of dividing Saccharomyces cerevisiae cells and inhibition of cell viability compared to control. The cytotoxicity of the hydro-alcoholic extract of kanchnar guggulu, shown by its antimitotic and antiproliferative effects, may be due to the presence of flavonoids and phenolics.
CONCLUSIONKanchnar guggulu exhibited a cytotoxic effect by inhibiting cell division (antimitotic) and reducing cell proliferation. These results substantiate its potential for the treatment of cancer and support its traditional use in the treatment of cancer.
