The present study examines the effects of dietary saturated (hydrogenated coconut oil) and polyunsaturated (salmon oil) fats on the composition and metabolism of lipoproteins in growing rats fed on protein-deficient diets. Four groups of rats were fed on the following diets for 28 d: 200 g casein+50 g coconut oil (COC)/kg, 20 g casein+50 g coconut oil (COd)/kg, 200 g casein + 50 g salmon oil (SAC)/kg, 20 g casein+50 g salmon oil (SAd)/kg. Both protein-deficient groups exhibited low concentrations of protein and triacylglycerol (in serum, very-low-density lipoprotein (VLDL), low-density lipoprotein-high-density lipoprotein, (LDL-HDL1) and HDL2-3), of cholesterol (in LDL-HDL1) and of phospholipids (in VLDL). Furthermore, serum and VLDL cholesterol concentrations were also reduced in the SAd group. Compared with rats given 200 g casein/kg diets, those fed on low-protein diets presented lower linoleic and arachidonic acid levels, in serum phospholipids and a dramatic decrease in the polyunsaturated: saturated fatty acid value. Relative amounts of linoleic and arachidonic acids in phospholipids of VLDL and HDL2-3 were also lowered in the Cod group but not in the SAd group. However, proportions of 22:5n-6 and 22:6n-3 in VLDL and HDL2-3 phospholipid fractions were enhanced in the Cod and SAd groups respectively. The most affected apolipoproteins (apo) were apo B100 and apo B48 in rats fed on protein-deficient diets, apo A1 and apo E in the Cod group, and apo AIV, in the SAd group. Compared with rats fed hydrogenated coconut oil diets, those fed salmon oil diets had enhanced LDL-HDL1 and HDL2-3 but lower VLDL total apolipoproteins (mainly due to a fall in apo B100, and apo B48). Arachidonic and eicosapentaenoic acids, which are impaired by protein deficiency, are the precursors of prostaglandins, thromboxanes and leukotrienes which are implicated in a number of regulatory processes. Our results demonstrate that protein malnutrition is associated with impaired metabolism of arachidonic and eicosapentaenoic acids. Protein malnutrition and essential fatty acid (EFA) deficiency are characterized by many common clinical features and the Link between the two may be an impaired production of eicosanoids, since arachidonic and eicosapentaenoic acids are the precursors of these important metabolic regulators. Because of the apparent involvement of EFA deficiency in the aetiology of protein malnutrition, it may he prudent to include adequate amounts of EFA in diets of infants suffering from kwashiorkor.

A deficiência de nutrientes durante os períodos críticos do desenvolvimento tem sido associada com maior risco para desenvolver obesidade e diabetes Mellitus na vida adulta. Um dos mecanismos propostos refere-se à regulação do comportamento alimentar e às alterações do metabolismo energético do músculo esquelético. Recentemente, tem sido proposta a existência de uma comunicação entre o hipotálamo e o músculo esquelético a partir de sinais autonômicos que podem explicar as repercussões da desnutrição perinatal. Assim, esta revisão tem como objetivo discutir as repercussões da desnutrição perinatal sobre o comportamento alimentar e o metabolismo energético muscular e a comunicação existente entre o hipotálamo e o músculo via sinais adrenérgicos. Foram utilizadas as bases de dados MedLine/PubMed, Lilacs e Bireme, com publicações entre 2000 e 2011. Os termos de indexação utilizados foram: feeding behavior, energy metabolism, protein malnutrition, developmental plasticity, skeletal muscle e autonomic nervous system. Concluiu-se que a desnutrição perinatal pode atuar no controle hipotalâmico do comportamento alimentar e no metabolismo energético muscular, e a comunicação hipotálamo-músculo pode favorecer o desenvolvimento de obesidade e comorbidades durante o desenvolvimento.

The composition of the raw legumePhaseolus vulgarisL. var.athropurpurea(PhVa) and its effects on the metabolism of young growing rats have been evaluated. The levels of protein, unsaturated fatty acids, carbohydrate, fibre and bioactive factors present in PhVa were comparable with those in otherPhaseolus vulgarisvarieties. However, the lectins of PhVa were predominantly of the leucoagglutinating type, and concentrated in the albumin protein fraction. Rats fed a diet (110 g total protein, 16·0 M/g) in which PhVa meal provided about half of the protein excreted high levels of N in faeces and urine, and grew more slowly, than rats fed a high-quality control diet (ad libitumor pair-fed). Small intestine, large intestine and pancreas weights were increased (by almost 100 %,P<0·05), whilst skeletal muscle, thymus and spleen weights were reduced. Blood insulin 16·20v.0·50 m/,P<0·05, thyroxine, glucose, protein (60·5v.48·3 /,P<0·05) and LDL-cholesterol were lowered, whilst glucagon (155·3v.185·4 n/,P<0·05), triiodothyronine and urea were elevated, as were urinary urea, creatinine and glucose. These changes in the local (gut) and systemic metabolism of rats were probably mediated primarily by lectins in PhVa, which were concentrated in the albumin protein fraction, whereas in many otherPhaseolus vulgarislines they are distributed across the globulin and albumin fractions.
