Objective: Monitor the ameliorative impact of Nigella sativa on fasting blood glucose and serum testosteronelevels in polycystic ovarian syndrome caused by letrozole in mice. Study Design: Laboratory based randomized control trial. Place and Duration of Study: Anatomy department, Army Medical College in teamwork with National Instituteof Health. Time span is Dec 2014 Dec 2015. Methodology: Total 40 mature female BALB/c mice were chosen and distributed in four groups (ten mice in each one). Group 1 was given normal diet. Rests of three groups were treated with Letrozole at dose of 1 mg/kg body weight once daily for eight weeks. Group 3 was also given Nigella sativa seeds powder at dose of 10 g/kg body weight once daily starting at 22 day and continued up to eight weeks. Group 4 was treated with Nigella sativa oil at a dose of 4 ml/kg body weight once daily starting at 22 day and continued up to eight weeks. At termination of trial, fasting blood glucose level (FBG) was recorded by taking blood sample by glucometer from mouse lateral tail vein after 12 hours fasting. Mice with blood glucose level 250-464 mg/dl were marked hyperglycemic. Final blood sample was taken through cardiac puncture for serum testosterone evaluation. Results: Fasting blood glucose and Serum testosterone levels were raised in group 2 animals in comparison togroup 1 while they were reduced remarkably in group 3 and 4 in comparison of group 2. Conclusion: Nigella sativa seeds in both solid and liquid state leave..................

Objective: To study the effect of fine particulate matter exposure in instigating depressive-like response and total body weight changes in C57BL/6J mice. Study Design: Laboratory-based experimental study. Place and Duration of Study: Anatomy Department, Army Medical College, Rawalpindi, in collaboration with the Military Hospital, Rawalpindi and the National Institute of Health (NIH), Islamabad, from Jun to Sep 2020. Methodology: Thirty male and female C57BL/6 mice, 8 weeks of age, weighing 37 ± 2 gm were obtained from NIH, Islamabad. They were retained in separate cages in the animal house of NIH under standard laboratory conditions. The animals were divided into two groups, 15 mice in each group (8 males and 7 females) Group A was marked as control, received regular diet and water ad libitum. Group B (experimental group) received dynamic inhalation of 3 mg/m³ fine particles (soot) through air circulation for 6h/d for 12 weeks, in a plastic cabin measuring 2x2x2 feet fitted with two small fans for evenly distribution of PM. The initial and final weight of animals was recorded, and a tail suspension test was performed to assessdepression in form of immobility. Result: The experimental group after exposure to fine particulate matter showed decreased activity and behavioural deficits with p-value <0.001 and loss in total body weight as compared to the control group with a p-value <0.001. Conclusion: Fine particulate matter has a significant effect on behaviour and cognition. It also causes a decrease in the total body weight of animals due to stress and agitation.
