Serum concentration of folate, vitamin B12 and homocysteine in patients of cervical cancer

The aim of this study was to evaluate the risk of cervical cancer in relation to serum concentration of folate, vitamin B12 and homocysteine. Fifty patients with invasive cervical cancer and 50 VIA negative cases (control) with age range of 30-65 years were included. Majority of the patients had significantly low level of serum folate and B12 than those in the control group.  In contrast, serum homocysteine level was significantly high in cases than those in the control group. The Pearson correlation coefficient test showed a significant negative relationship between serum folate, vitamin B12 and serum homocyteine. However, there was no significant association between stage of cervical cancer and level of serum homocysteine. In conclusion, a significantly low level of serum folate, vitamin B12 and high level of serum homocysteine were observed in patients with invasive cervical cancer

Effects of exposure to imidacloprid contaminated feed on the visceral organs of adult male rabbits (Oryctolagus cuniculus)

The best-known and often used systemic, broad-spectrum neonicotinoid pesticide is imidacloprid (IMI). This study was carried out on adult male rabbits (n = 12) to assess the residual effects of exposure to IMI-contaminated diet on the liver, lung, heart, and kidney. Pesticide-exposed rabbits (n = 6) received IMI contaminated green grass (Bildor® 0.5 ml (100 mg)/L water) every alternative day once daily for up to 15 days. The remaining rabbits were fed a standard diet free of pesticides as a control. During routine monitoring of the rabbits throughout the experiment, there were no apparent toxic symptoms identified. On days 16, after deep anesthesia blood and visceral organs were collected. The levels of hepatic serum aspartate transaminase and alanine transaminase were considerably elevated in IMI-exposed rabbits (p ≤ 0.05). Thin layer chromatography revealed that the residue of IMI was at the detectable level in the liver and stomach. Histopathologically, the liver revealed coagulation necrosis with granulomatous inflammation and congestion in portal areas with dilated and congested central veins. The lungs showed congestion of blood vessels and granulomatous inflammation around the terminal bronchiole. Accumulations of inflammatory cells were observed in the cortico-medullary junction in the kidney. The heart showed necrosis and infiltration of mononuclear cells within the cardiac muscles. The findings of the current study emphasize that IMI-contaminated feed exposure causes toxicity into the cellular level of different visceral organs of adult male rabbits and it may also cause the similar toxic effects of the other mammals specially the occupationally exposed persons
