The effect of garlic formulation on some hematological parameters and organ weight of male and female Wister albino rats

The study was conducted to investigate the impact of garlic formulation on certain haematological parameters and organ weights in both male and female rats. Haematological data, including the count of red blood corpuscles (RBC), the volume of packed cells (PCV), the count of white blood corpuscles (WBC), and the count of platelets, were evaluated using a fully automated haematology analyser. The liver, right kidney, left kidney, heart, and spleen of the rats were weighed to determine their respective organ weights. A total of thirty (30) albino Wister rats, consisting of both males and females, were randomly assigned to five groups, with six animals in each group. Group 1 acted as the positive control and was given 100% standard feed. Group II rats were given a mixture of 10% garlic and 90% feed. Group III animals were provided with a diet consisting of 20% garlic and 80% feed. Group IV received a diet containing 40% garlic and 60% feed. The final group, Group V, was fed a diet consisting of 80% garlic and 20% feed daily for a period of 21 days. The feed formulation was assessed at concentrations of 10, 20, 40, and 80 g/dl, based on the weight of the animal. The findings indicated a noteworthy (P<0.05) reduction in white blood cell count (WBC) and lymphocyte count (LYM). There were no statistically significant changes (P>0.05) observed in the levels of haemoglobin (HGB), haematocrit (HCT), mean corpuscular haemoglobin concentration (MCHC), mean corpuscular volume (MCV), and mean corpuscular haemoglobin (MCH) when compared to the control group. Furthermore, there was a noteworthy (P<0.05) reduction in HGB, MCV, and MCH when the rats reached a body weight of 80 g/100dl. The results indicated a statistically significant (P<0.05) reduction in the weight of the left kidney, heart, and spleen, as well as in the liver and right kidney weights at 20, 40, and 80 g/dl body weight. There were no statistically significant differences (P>0.05) in the body weight of the liver and right kidney, which were both 10g/dl. Ultimately, the use of garlic formulation in appropriate dosages can impact certain haematological markers and the weights of organs.
