Diet Induced Obesity

In the present study, the methanolic extract of Moringa oleifera leaves (MEMOL) was evaluated for antiobesity activity in rats. The antiobesity potential of MEMOL was studied against high fat diet-induced obesity (HFD) in rats. In this study, chronic administration of HFD in rats produced hypercholesterolemia (116.2 ± 0.27 mg/dL), which led to an increase in the body weight (225 gr), total cholesterol, triglycerides (263.0 ± 4.69 mg/dL), and attenuation in the levels of HDL (34.51 ± 2.20 mg/dL) as well as changes in body temperature of animals. Treatment of obese rats with MEMOL for 49 days resulted in a significant (P<0.001) change in body weight, total cholesterol, triglycerides, and LDL level along with a significant (P<0.001) increase in body temperature as compared to the HFD-induced obesity. MEMOL treated rats also showed a significant decrease in the level of liver biomarkers, organ weight, and blood glucose level. Further, rats treated with MEMOL (200 mg and 400 mg/kg) show reduced atherogenic index (1.7 ± 0.6 and 0.87 ± 0.76). The results indicate that the rats treated with Moringa oleifera (MO) have significantly attenuated the body weight without any change in the feed intake and also elicited significant thermogenic effect and to act as hypolipidemic and thermogenic property in obesity related disorders.

Abstract Introduction: This study investigated short- and long-term effects of khat (Catha edulis) on hypophyseal, epididymal and testicular morphology, body weight and temperature changes and haematological parameters of rabbits. Materials and Methods: Twenty five male New Zealand White rabbits, divided into five groups were used. First four groups were administered, via intra-gastric tube, 1.5, 4.5, 13.5 and 40.5 g/kg body weight respectively of khat extract thrice a week for 8 weeks while controls received normal saline. Short-term and long-term effects were evaluated for hypophyseal, epididymal and testicular morphology, body temperature as well as body weight changes, food consumption and haematological parameters. Data on haematological parameters, body weight changes, body temperature and food consumption was done using one-way ANOVA at 95% confidence interval using SPSS version 12.0. Results: There was vacuolation in spermatogonia and spermatocytes at high doses while epididymides and hypophyses were unaffected. A significant decrease (P<0.05) in body weight of treatment groups correlated with reduced food intake with increasing doses and chronicity of exposure. Packed cell volume, red blood cell count and haemoglobin concentration decreased while white blood cell count increased with increasing doses. Conclusion: Khat extract had direct effects on spermatogenesis compounded by poor body weight gain, hyperthermia and blood volume loss.

The study was conducted on 10 local breed rabbits, of 1-2 years age, of 1- 1.5 kg body weight. They were feed concentrated and green food, and left ad libitum for water, and kept in room of 20- 25 oC. The animals divided into two groups of 5 each. First as treated group received the plant in powder form mixed with the food at a dose rate of 5 g/ animal / day for three weeks , while the second left without exposure as a control group .The main dependent parameters in the study were , clinical parameters ( body temperature , heartbeat , respiratory rate, body weight , in addition to monitor any abnormal signs appear on the animals . While the main hematological parameters were included , RBC count , WBC count , Hb concentration,PCV percentage , Red cell indices , Bleeding time and Clotting time. The body temperature, respiratory rates, heart rate were increased .The body weight decreased .The bleeding time and clotting time were prolonged. The erythrocyte count, Hb concentration, and MCV values were decreased; PCV and MCHC did not showed any significant changes. The MCH increased. The total leucocytes count and the basophiles percentage did not showed any significant changes. The Heterophils and monocytes percentage increased .The lymphocytic and Eosinophil percentage were decreased during the study.

Dose Levels

Body temperature changes induced by two dose levels of chlorpromazine HCl were compared in the rat, hamster, ground squirrel and pigeon. In addition, the effect of cold exposure was determined in the hamster. All three mammalian species showed a rapid decline in temperature by the first 2 hours following the injection of 10 mg/kg body weight of chlorpromazine, after which a gradual return toward normal was evident. However, a further decrease in body temperature occurred at the higher dose level of chlorpromazine (100 mg/kg body weight) and the degree of hypothermia varied with the species. The hamster appeared to be the most resistant to this compound while the ground squirrel was the least resistant. The female of the three mammalian species was less susceptible than the male. The combination of cold exposure and chlorpromazine in the hamster produced a decline in body temperature that was greater than that produced by either stressor alone. Again a sex difference was noted. The pigeon failed to respond to the drug in any degree comparable to that seen in the mammals. This was thought to be due to the lack of effect on respiration, an important thermoregulatory mechanism in the bird.

Dwarf Chicken

A study was undertaken to investigate the feasibility of hypothyroidism as an explanation for the smaller body size and lower metabolic activity of the recessive sex-linked dwarf chicken. A significant increase in body weight gain and feed intake for dwarf chicks with little change in these parameters for normal chicks receiving a diet supplemented with Protamone (brand name for iodinated casein) suggests a hypothyroidic state for the dwarfs. Similarly, a significantly lower body temperature, oxygen consumption and basal metabolic rate with a higher percentage of carcass fat in dwarf chicks as compared with normal ones supports the above hypothesis. Protamone supplementation of the diet increased body temperature and metabolic rate, and altered the carcass composition of the dwarfs to values closer to that of normal chicks, again suggesting a low thyroxine output for the dwarfs.

Thyroid State

A hyperthyroid state was induced and maintained in 17 dogs for 2–10 months by the administration of massive amounts of thyroid hormone. The great tolerance of this species to such large doses was striking. The clinical signs characteristic of hyperthyroidism in other mammals were observed including significantly increased caloric intake, oxygen consumption, heart rate, and body temperature. The laboratory findings included polycythemia, markedly increased levels of protein-bound iodide (PBI), increased turnover rates of l-thyroxine, and a decreased urinary excretion of inorganic iodide. Unlike other species the hyperthyroid dogs did not demonstrate marked reductions in body weight or serum cholesterol. Salivariectomy neither hastened nor enhanced the onset of exogenous hyperthyroidism in the dog. Measurements of the rate of disappearance of I131 l-thyroxine from the plasma and the rate of appearance of radioactive iodide in the urine indicated that the salivary glands in the intact dog are effective sites of deiodination and iodide excretion. This activity, however, is not the sole regulator of the level of circulating thyroid hormone and thus of the thyroid state.
