ABSTRACT
Embryonic toxicity of lambda-cyhalothrin (LCH) and the mitigating properties of extra virgin olive oil (EVO) and vitamin E were investigated in golden black variety of chick embryos. Fifty fertilized eggs distributed in 5 groups received their respective group treatments at zero days of incubation were recovered after 14 days of incubation and fixed in fixative for 48 h for further studies. Results showed that treatment with LCH caused embryonic death, growth retardation and developmental abnormalities such as limbic developments, reduced muscular growth, and embryonic cataract. Post treatment with vitamin E and EVO alone significantly improved all these developmental defects. Morphometric readings also showed that embryos treated with combined dose of vitamin E and EVO had more resemblance towards the control group embryo. These findings suggested that the use of vitamin E and EVO together during pregnancy have the potential to curtail these accidental, environmental and work place exposures of LCH.
ABSTRACT
OBJECTIVE: Type 2 diabetes mellitus, due to its deteriorating effect on the immune system, makes a person susceptible to various other diseases, such as tuberculosis. The alarming increase in the number of diabetes mellitus cases in Pakistan may be a contributing factor to the increased tuberculosis incidence. The expression of cell adhesion molecules such as intercellular adhesion molecule-1 (ICAM-1) is important in determining cell permeability, and the latter's altered expression may ease the entry of infectious agents into the cell. Therefore, the present study evaluated the role of ICAM-1 in type 2 diabetes and tuberculosis patients so that a potential link between these 2 epidemics could be found. METHODS: To explore this hypothesis, the expression of ICAM-1 was measured tested in 3 groups of subjects: group I consisted of 100 healthy individuals (control), group II consisted of 100 type 2 diabetics, and group III consisted of 100 individuals with both type 2 diabetes and tuberculosis. Demographic information was obtained from all the participants and compared by group and ICAM-1 levels in the blood were determined by ELISA. RESULTS: The results revealed that, in comparison to group I, the individuals of group II had significantly (p ≤ 0.05) increased levels of ICAM-1, making them more prone to infection (by promoting the increased invasion of mycobacterium) and hence at increased risk of contracting tuberculosis. CONCLUSION: In conclusion, the present study demonstrated that elevated levels of ICAM-1 in patients with type 2 diabetes mellitus are likely associated with the development of tuberculosis.
