Presence of atrazine in the biological samples of cattle and its consequence adversity in human health

Cattle can be considered as an important source for herbicides through nutrition. Therefore, herbicide residue in animal products is a potential human exposure to herbicides causing public health problems in human life. Triazines are a group of herbicides primarily used to control broadleaf weeds in corn and other feed ingredients and are considered as possible human carcinogens. To evaluate trace residue of these pollutants molecular imprinted solid phase extraction [MISPE] method has been developed, using biological samples. Blood samples were taken from the jugular vein of 45 Holstein cows in 3 commercial dairy farms in Khuzestan Province, Iran. Urine samples were also taken from the cows. The mean +/- SD concentrations of atrazine in serum and urine samples of the study group [0.739 +/- 0.567 ppm and 1.389 +/- 0.633 ppm, respectively] were higher [P < 0.05] than the concentrations in serum and urine samples of the control group [0.002 +/- 0.005 ppm and 0.012 +/- 0.026 ppm, respectively]. Atrazine in the feed ingredients ingested by cattle could be transferred into the biological samples and consequently can be considered as a potential hazard for the public health

metabolic syndrome

The metabolic syndrome is frequent and corresponds to the association in the same patient of different metabolic and hemodynamic factors that increase the risk for diabetes and for cardiovascular diseases. It is essential to screen out these patients who have a high cardiovascular risk so that prevention management can be targeted. These efforts are essentially based on promoting physical activity and on following a balanced diet

Adrenocotical carcinoma with invasion of inferior vena cava

Adrenal carcinomas are rare and the incidence of their extension to the inferior vena cava is between 15 to 20% of the cases. We report an adrenal carcinoma with a thrombosis to the inferior vena cava and we review the management of these cases which is essentially surgical and adapted to the extension of the thrombosis

[Oculomotor paralysis in diabetes. about 2 case]

Two cases of oculomotor paralysis in diabetic patients are reported. These two cases emphasize the importance of ocular motility examination in diabetic patients and the need in the etiologic investigation for oculomotor paralysis in diabetic patient to exclude a neuro-surgical emergency [tumor or anevrysmal compression]. This study shows also the importance of glycemic control and of vascular risk factor management in the treatment and prevention of diabetic oculomotor paralysis

[Determination of bovine subclinical ketosis by measurement of beta-hydroxy butyrate serum values in dairy farms of Kerman]

Objective: determination of frequency of subclinical ketosis of dairy farms of Kerman by measurement of beta hydroxy butyrate

Design: cross sectional study

Animals: a total of 90 lactating cows in 3-6 weeks of lactation

Procedure: in this study the frequency of subclinical ketosis in 90 cows of 1 dairy farms containing 3542 cows were evaluated. Cows were selected in 3 to 6 weeks after parturition. The blood samples of each week for each cow were submitted to laboratory for detection of BHB and glucose. Statistical analysis: Student t-test, analysis of variance

Results: thirteen [14.4%] and 5 cows [5.55%] have showed ketonemia with cut of point of BHB levels [> 1.2 mmol/l] and [>I .7 mmol/l] respectively. The percentage of subclinical ketosis in city of Kerman is low but this is similar to some reports of the other parts of the world with range of 7-34%. The range of the glucose levels in these cows was 28-42 mg/dl and there is a reverse relationship between level of glucose and ketonemia

Clinical implication: it seems that some percentages of our daires suffer from subclinical ketosis that is effect on lactation level and some other organs mechanisms. However, further investigations should be gathered about the real cut of point of BHB values in Iranian cows

Les Aplasies me'dullaires en me'decine interne [a'propos de 32 cas]

Our study was about 32 cases of medullary aplasia managed at the Ibn Sina CHU between 1990 and 1994. It's an uncommon disease but a dangerous one affecting mainly the young adult. It's manifested clinically at the variable degrees by an anemic, hemorrhagic and infectious syndrome. The diagnosis is indicated by hematologic disorders, but well confirmed by the bonymedullary biopsy. Although the origin for the major cases is unknown, the etiologic research has to be conducted because it helps partly for the prognosis. In all cases, an hematologic reanimation is necessary, whereas the androgenotherapy is the more effective option for low risk forms. In all the other cases, the bone marrow graft is the best treatment. The antilymphocytic serum can be the second alternative
