Abstract
Background: Recent studies have shown that nicotinic-amide and niacin induce significant reductions in serum phosphorous in patients undergoing hemo-dialysis. The aim of the present study was to determine the effect of nicotinic acid on serum phosphorous level in patients undergoing long-term hemodialysis.
Materials and Methods: In an 8-week cross-over randomized double-blind clinical trial, 37 patients were assigned to nicotinic acid or placebo groups with titration from 400 to 1000 mg/ daily. A 2-week washout preceded the switch from nicotinic acid to placebo or vice versa. Statistical analysis was performed using paired- sample t test.
Results: The mean dose of nicotinic acid at the end of the period was 740±204 mg/daily. Nicotinic acid showed a significant decrease in serum phosphorus after the 8-weeks treatment however no significant changes occurred in the placebo group (P =0.01). Also, nicotinic acid resulted in an increase of HDL cholesterol levels after 8 weeks.
Conclusion: Nicotinic acid can lead to a decrease and an increase in serum phosphorous and HDL cholesterol levels, respectively. However, there is need for longer trials with larger sample sizes for determining the most effective doses of this drug.

Abstract
Background and Aim: The history of using bleomycin in a hospital indicates a series of vast reactions in biological systems caused by direct and indirect effects. The biological responses of the biological system make this process more complicated. Increasing the prevalence and the incidence of cancerous diseases that are treated with bleomycin is of paramount importance. The aim of this study was to evaluate the effect of niacin on reducing the complications of bleomycin consumption in human model.
Materials and Methods: This experimental study was done as case-control and double-blind clinical trial. Of the cancer patients referred to Khansari hospital in Arak that underwent the bleomycin monotherapy, 20 subjects were randomly selected and divided into two groups. Each person in the first group (control) received 2 placebos per day (every 12 hours) and the second group (treatment) were given two pills of niacin (each pill: 100 mg) daily, and the results were recorded and analyzed.
Findings: A comparison between treatment and control groups showed a reduction in nausea and vomiting in the treatment group compared to the control group. The sense of taste disorder complication was reduced in the treatment group compared with the control group and this difference was statistically significant (p <0.05).
Conclusion: The results suggest that niacin can decrease the side effects of cancer treatment from different directions, including side effects, nausea, vomiting, loss of sense of taste, but its impact on respiratory problems probably because of the damage caused by bleomycin was not significant.
