Effects of Supplemental Threonine on Antioxidant Enzyme Activities and Haemato-biochemical Profile of Commercial Broilers in Sub-Tropics

Present study was aimed at investigating the effects of threonine supplementation on antioxidant enzyme activities and haemato-biochemical profile of commercial broilers in sub-tropics. Three hundred thirty -day old straight run commercial broiler chicks (Vencobb-400) with initial average body weight of 44.04±0.42g were allocated into five experimental groups, in a completely randomized design (CRD) with 42 days experiment. Groups were formed according to the dose of supplemental L-threonine in various rations i.e. NRC specification, 100% of Vencobb-400 strain specification, 110% of Vencobb-400 specification, 120% of Vencobb-400 specification and 130% of Vencobb-400 specification group. The mean serum GSH-Px and serum catalase concentration increased linearly {(p=0.001) and (p=0.04), respectively} whereas the mean serum SOD level increased both linearly (p=0.002) and quadratically (p=0.04) with the increasing levels of supplemental L-threonine. Among the hematological parameters of blood, the H:L ratio decreased linearly (p=0.02) with the increasing levels of threonine. The serum glucose and total protein concentration increased linearly (p=0.002) with the increasing levels of supplemental L-threonine. There was a linear increment (P<0.001) in serum globulin level with a linear decrease (p<0.05) in albumin: globulin ratio on increased levels of supplemental L-threonine in the ration. There was a linear decrease (p<0.001) in cholesterol and VLDL level with the increasing levels of supplemental L-threonine, however, a linear increment (p=0.04) in the serum HDL level was noticed. It may be concluded that L-threonine supplementation at 130% threonine (of Vencobb-400 specification) has a better antioxidant function and better haemato-biochemical profile

Atypical coarctation with severe hypertension: a case report.

A young man of 16 years presented with sudden onset of right sided headache and vomiting for one day. No neurological or visual disturbances were noticed. On examination his BP was 240/120 mmHg. All upper extremity pulses were felt but from the femoral artery down to arteria dorsalis pedis these were absent. He was diagnosed as a case of coarctation of aorta following various biological and radiological investigations. After confirming the findings on aortography an aortoplasty was attempted with a long cordis balloon used to dilate the middle aortic lesion of 15 mm.
