Effect of oral balck cumin (Nigella Sativa) supplement on the expression of genes involved in adipogenesis using NGS method and serum concentrations of liver enzymes and lipid profiles among obese women
Design
This is a cross-over randomized placebo controlled double blind clinical trial.
The target group consisted of 24 obese women who will randomly assigned into one of the two groups. Duration of the intervention consisted of 2 periods of 2 months;
Settings and conduct
Obese healthy women who will be referred to Imam Ali hospital in Yazd city, will be recruited and will be randomly divided into 2 groups of supplement and placebo; capsules will be given in a double-blind process; participants and researchers will be blinded to the content. Blood collection will be done to assess the biochemical factors at the beginning and the end of each period; abdominal tissue samples will be randomly taken from 10 women at the end of each intervention period in the Internal section of hospital. RTPCR test will be performed on blood samples. after a 1-month washout, all the mentioned procedures will be done for the second period.
Participants/Inclusion and exclusion criteria
Inclusion criteria are healthy obese women aged 25 to 55 years old with the BMI ranges of 30 to 35 kg/m2; exclusion criteria includes the presence of allergy to the supplements during the intervention period or the use of less than 10% of the supplements.
Intervention groups
the treatment group will receive 2 pearls per day , that each pear contain 1000 ml of nigella sativa for 2 periods of 2 months;
the placebo group will receive 2 pearls per day , that each pear contain 1000 ml of placebo for 2 periods of 2 months;
one month of washout period will be performed between the 2 periods.

Inclusion/Exclusion criteria
Inclusion criteria:
Obese women whose obesity was defined according to WHO criteria.
The BMI range of participants should be between 30 to 35 kg/m2.
Age ranges should be 25 to 55 years old.
Healthy obese women will be interred to the study.
Exclusion criteria:
Having replacement treatments like Hormone or supplemental vitamins or weight loss drugs;
tobacco and alcohol use
chronic or acute inflammatory disease ; heart valve disease ; short bowel syndrome ; allergies

Randomization (investigator's opinion)
Randomized
Randomization description
For the primary recruitment of participants, stratified randomization method will be used based on participants age including 25-40 and 40-55 years old. and the random number table will be used to assign participants to the intervention and control (placebo) groups.
Blinding (investigator's opinion)
Double blinded
Blinding description
The appearance and shape of the Supplements and placebos pearls will be similar; every complete packs will be given once for the first 2 months of the intervention and once before the second 2 months of the intervention. A and B labels will be fixed on the bottles of pearls by someone irrelevant to the entire study. Participants and researchers will be blinded to the contents in the bottles through out the study.
