The vagus nerve (VN) and spleen represent a complex interface between neural and immunological functions, affecting both energy metabolism and white adipose tissue (WAT) content. Here, we evaluated whether vagal and splenic axis participates in WAT mass regulation in obese and non-obese male Wistar rats. High doses of monosodium glutamate (M; 4 g/Kg) were administered during the neonatal period to induce hypothalamic lesion and obesity (M-Obese rats). Non-obese or Control (CTL) rats received equimolar saline. At 60 days of life, M-Obese and CTL rats were randomly distributed into experimental subgroups according to the following surgical procedures: sham, subdiaphragmatic vagotomy (SV), splenectomy (SPL), and SV + SPL (n = 11 rats/group). At 150 days of life and after 12 h of fasting, rats were euthanized, blood was collected, and the plasma levels of glucose, triglycerides, cholesterol, insulin, and interleukin 10 (IL10) were analyzed. The visceral and subcutaneous WAT depots were excised, weighed, and histologically evaluated for number and size of adipocytes as well as IL10 protein expression. M-Obese rats showed higher adiposity, hyperinsulinemia, hypertriglyceridemia, and insulin resistance when compared with CTL groups (p < 0.05). In CTL and M-Obese rats, SV reduced body weight gain and triglycerides levels, diminishing adipocyte size without changes in IL10 expression in WAT (p< 0.05). The SV procedure resulted in high IL10 plasma levels in CTL rats, but not in the M-Obese group. The splenectomy prevented the SV anti-adiposity effects, as well as blocked the elevation of IL10 levels in plasma of CTL rats. In contrast, neither SV nor SPL surgeries modified the plasma levels of IL10 and IL10 protein expression in WAT from M-Obese rats. In conclusion, vagotomy promotes body weight and adiposity reduction, elevating IL10 plasma levels in non-obese animals, in a spleen-dependent manner. Under hypothalamic obesity conditions, VN ablation also reduces body weight gain and adiposity, improving insulin sensitivity without changes in IL10 protein expression in WAT or IL10 plasma levels, in a spleen-independent manner. Our findings indicate that the vagal-spleen axis influence the WAT mass in a health state, while this mechanism seems to be disturbed in hypothalamic obese animals.

In the present feeding trial, responses of laying hens, kept at high ambient temperature, to various dietary ratios of linoleic acid (LNA) to α-linolenic acid (ALA) and vitamin A levels on performance and egg characteristics were evaluated. A total of 360, 40-wk-old, Leghorn laying hens were fed on diets with various combinations of canola oil and linseed oil to achieve LNA to ALA dietary ratios of 20:1, 10:1, 4:1, 2:1, 1:1 and 1:2, each supplemented with 3000 IU or 10000 IU vitamin A/kg of diet. The diets were fed in a 6×2 factorial Completely Randomized Design that continued for 12 weeks. Feed intake, weight gain, egg production and egg quality traits were recorded during the trial. Decreasing dietary LNA to ALA ratio in the diet affected negatively (P<0.05) on body weight gain and yolk percentage in laying hens. While, feed intake, hen-day and hen-housed egg production, feed conversion ratio (FCR) per dozen of eggs and shell quality remained unaffected (P>0.05) by dietary treatments, with the exception of FCR per kg eggs, egg weight and egg-shell thickness which responded significantly (P<0.05) to various dietary treatments. Although the dietary ratio of LNA to ALA of 4:1 or less could produce eggs by the hens with desirable quantities of n-6 and n-3 poly unsaturated fatty acids – that are characteristics of functional diets – the performance of laying hens in terms of body weight gain and egg-yolk percentage was slightly compromised.

Young male Zucker lean (Fa/-) and obese (fa/fa) rats were fed the alpha-adrenergic blocking agent phenoxybenzamine as a dietary admixture for 35 days. In lean and obese rats, phenoxybenzamine treatment decreased significantly body weight gain, food consumption, grams of carcass fat, and grams of carcass protein. Lean rats exhibited reduced fat cell size and number in retroperitoneal, epididymal, and inguinal fat depots. Obese rats treated with phenoxybenzamine exhibited significantly decreased numbers of fat cells in the retroperitoneal, epididymal, and inguinal fat depots and a small decreased cell size in the inguinal fat depot only. The levels of carcass fat and protein and fat cell number in obese and lean rats treated with phenoxybenzamine for 35 days were similar to pretreatment values in agreement with the lack of body weight gain. Although values in agreement with the lack of body weight gain. Although rats exhibited marked decreases in fat accumulation during phenoxybenzamine treatment, fat cell size and number returned to control values during the posttreatment period with a marked hyperplasia occurring particularly in the retroperitoneal fat depot of obese rats. Serum levels of insulin were suppressed and free fatty acid levels increased in obese rats during phenoxybenzamine treatment, suggesting a stimulation of the sympathoadrenal system. This study shows that despite severe restrictions in fat cell proliferation during the rapid-growth phase of the obese Zucker rat, the mechanisms for cellular proliferation and fat deposition remain intact.
