ABSTRACT
A2-year-old cachectic cross-breed gelding was admitted to Veterinary Teaching Hospital of University of Tehran following the onset of a marked respiratory distress, coughing and ventral edema. Clinical examinations indicated harsh respiratory and expiratory sounds as well as jugular vein distention. The respiratory and heart rates were 35/min and 60 bpm, respectively. A grade III/IV pansystolic murmur with the PMI on the tricuspid valve, which could be heard on the left side, was detected. Sinus tachycardia was revealed by electrocardiography. Rupture of the chorda tendineae of the tricuspid valve, pulmonary artery regurgitation, pulmonary artery hypertension, tricuspid valve regurgitation, pulmonary artery, and right ventricular dilation were also found in echocardiography. These findings were confirmed at post mortem examinations. On the basis of the findings, chorda tendineae rapture of the tricuspid valve and right side heart failure due to primary pulmonary hypertension were diagnosed
ABSTRACT
Motilides mainly erythromycin have a great ability to increase abomasal emptying rate. The aim of this study was to evaluate the effect of erythromycin as a prokinetic agent on abomasal emptying rate and Immunoglobulin G absorption in neonatal calves. Twelve holstein neonate calves were divided into two groups [treatment and control] of 6 Calves each. One hour after birth, treatment and control groups were injected by erythromycine [8.8 mg/kg; IM] and normal saline [IM]. After 30 minutes, calves were fed by 3 liters of colostrum using esophageal tube. Venous blood samples for determination of plasma IgG were obtained at 1, 3, 6, 9, 12, 18, 24, 36, 48 hours and 5 and 7 days after birth. The results showed that administration of erythromycin caused a significant increase in the serum IgG level [20.394 mg/mL], compared to the control group [15.021 mg/mL]. This study revealed that erythromycin increases the serum IgG level probably through abomasal emptying acceleration
ABSTRACT
Modern technology and biotechnology have provided the possibility of gamete and embryo donations to infertile couples. Consequently, one of the important questions that have arisen is that "Is there a right to know one's biological parents?" To provide and answer this question, it is necessary, first, to determine, what one means by expressing the concept of "right". Four meanings have been identified for the concept. They are right-claim, right-liberty, right-power and right-immunity. Right-claim and right-liberty as the strong and weak claims are applicable to the problem at hand. To choose between the two meanings requires putting forth a well-established justificatory theory of rights. Rights are to protect the very humanity of human beings. This has been a basis for two basic values of human dignity and moral agency. Not knowing one's biological roots does not put in danger one's humanity or the two mentioned values. Therefore, we may only defend a right-liberty of knowing one's biological parents; a right that does not require the state and society to be active in making individuals know their biological parents. Nevertheless, in exceptional cases where the lack of that knowledge of the biological roots does endanger one's personhood and humanity, the weak claim can turn into a strong one
