ABSTRACT

This study determines the associations among serum lipid profiles, risk of cardiovascular disease, and persistent organic pollutants. Using Gas chromatography technique, the intensity of toxic pollutant residues in serum samples of Hypertensive patients were measured. Based on statistical analysis, the effects of different covariates namely pesticides, age, systolic blood pressure, diastolic blood pressure, and lipid profile duration was checked using the logistic regression model. Statistical computation was performed on SPSS 22.0. The P-values of F-Statistic for each lipid profile class are greater than 0.01 (1%), therefore we cannot reject the null hypothesis for all cases. The estimated coefficients, their standard errors, Wald Statistic, and odds ratio of the binary logistic regression model for different lipid profile parameters indicate if pesticides increase then the logit value of different lipid profile parameters changes from -0.46 to -0.246 except LDL which increases by 0.135. The study reports a significantly increased threat of cardiovascular disease with increased concentrations of toxic pollutants.


Este estudo determina as associações entre o perfil lipídico sérico, o risco de doença cardiovascular e os poluentes orgânicos persistentes. Por meio da técnica de cromatografia gasosa, mediu-se a intensidade dos resíduos de poluentes tóxicos em amostras de soro de pacientes hipertensos. Com base na análise estatística, os efeitos de diferentes covariáveis – ou seja, pesticidas, idade, pressão arterial sistólica, pressão arterial diastólica e duração do perfil lipídico – foram verificados usando o modelo de regressão logística. O cálculo estatístico foi realizado no SPSS 22.0. Os valores P da estatística F para cada classe de perfil lipídico são maiores que 0,01 (1%), portanto não podemos rejeitar a hipótese nula para todos os casos. Os coeficientes estimados, seus erros padrão, estatística de Wald e odds ratio do modelo de regressão logística binária para diferentes parâmetros do perfil lipídico indicam se os pesticidas aumentam, então o valor logit de diferentes parâmetros do perfil lipídico muda de -0,46 para -0,246, exceto LDL, que aumenta em 0,135. O estudo relata um aumento significativo da ameaça de doença cardiovascular com aumento das concentrações de poluentes tóxicos.

ABSTRACT

To study the effect of metronidazole, tinidazole, captopril and valsartan on the levels of zinc and magnesium in the serum of rabbits and humans and the histology of taste buds in rabbits. We conducted this study in the College of Medicine and Teaching Hospital, Basrah, Iraq from April 2005 to September 2006. It was in 2 parts: a clinical observational study of 54 patients treated with one of these drugs. The second part involved oral administration of metronidazole [45mg/kg], tinidazole [40mg/kg], captopril [3mg/kg] or valsartan [3mg/kg] or normal saline to 42 rabbits randomly. Serum zinc and magnesium were measured, and histological sections of tongues were examined for taste buds. In rabbits, oral metronidazole [13.6%] or tinidazole [7%] resulted in a significant reduction in serum zinc. Reductions in captopril [6.7%] and valsartan [4.2%] were smaller and insignificant. Body weight increased by 15.5gm [1391 +/- 225.3 gm to 1407 +/- 223.2 gm] in the control group, a lesser increase of approximately 8 gm, was found in the metronidazole group [1452 +/- 222.6 gm to 1460 +/- 221.9 gm]. Rabbit tongues showed moderate degeneration of taste buds caused by tinidazole, severe degeneration of captopril and minimal changes of valsartan. In humans, the drugs did not result in significant changes in serum zinc or magnesium. Approximately 73.3% of patients in the metronidazole group and 11.1% in the valsartan group had taste changes. It is concluded that metronidazole and tinidazole, but not captopril or valsartan resulted in a significant reduction of zinc level in rabbit, but not in human. Captopril and not valsartan caused severe degeneration in taste buds. Serum zinc level seems not to be related to taste buds changes
