Histological Changes and Ghrelin, P-Selectin, and Leptin Parameter in Patients with Hepatic Hydatidosis in Iraq.

Humans and animals are affected by hydatid cyst disease as a worldwide zoonotic disease, which is caused by the metacestode stage of Echinococcus spp. This study was performed to evaluate the histological change of liver and blood concentrations of biomarkers, such as ghrelin, p-selectin, and leptin, in humans infected with hydatid cyst. A total of 30 surgical specimens of liver and blood of infected humans and 30 healthy individuals as a control group were evaluated. Liver tissue sections in cases infected with hydatid cyst and control group, histological abnormalities in the liver, including fibrosis, increased inflammatory cells, dystrophic areas, and necrosis were compared in this study. In addition, serum leptin levels were significantly lower in patients with hydatid cyst disease QUOTE <0.05) than in the control group (P-value<0.05), whereas p-selectin and ghrelin levels significantly decreased in patients (P-value<0.05). The results of this research can be effective in improving and promoting the treatment programs of hydatidosis.

Effect of Smoking on Low-Density Lipoproteins Level in Human.

Smoking destroys the vascular system, increases plaque deposits in atherosclerosis, and increases inflammation. The present study was performed to determine the effect of smoking on the levels of low-density lipoprotein and very low-density lipoprotein in smokers. A cross-control study was carried out in the outpatient clinic in Baghdad, Iraq. The study was carried out 60 by individuals from February 2021 to July 2021. Participants in this study included adult smokers and non-smokers of both genders, and the levels of LDL and VLDL were determined using an Automatic Chemistry Analyze. The results revealed that the total number of smokers was 60 individuals from both genders; there was a significant difference in mean low-density lipoprotein and very low-density lipoprotein levels. There is a significant difference in LDL Values between non-smokers and smokers (129.853±7.880; P<0.05). Non-smokers showed lower LDL values (104.460±7.950; P<0.05). Regarding VLDL values, results revealed that smokers were showing higher values than a non-smoker (49.641±4.02), (28.986±1.676) respectively, P<0.05). LDL and VLDL levels are more prevalent in current cigarette smokers than in non-smokers. Heavy smokers have higher LDL and VLDL values for a cigarette than non-smokers, which is consistent with observations in other populations.
