The aim of this study was to evaluate the safety and anti-obesity effects of the Korean red ginseng extract in dogs. To this end, we fed healthy beagles a Korean red ginseng diet and/or snack for 8 weeks. The dogs were submitted to a thorough physical examination, complete blood count, serum biochemistry analysis, analysis of adipose tissue activity, and body fat-con- tent analysis by computed tomography (CT). At the end of the study period, the dogs that were fed the ginseng extract-diet/snack showed a significant decrease in body weight, body condition score and leptin levels relative to the baseline value. The CT findings revealed a decrease in body fat content in dogs fed the ginseng extract diet but not in those fed the ginseng-extract snack. The results of blood analysis did not show any meaningful changes in any of the dogs. All dogs tolerated the diet/snack well, and there were no adverse events. Our results suggest that the Korean red ginseng extract diet can potentially serve as an anti-obesity diet for reducing fat mass in dogs.
Dr. Artur Binda, a bariatric surgeon from the Orłowski Independent Public Teaching Hospital in Warsaw, discusses bariatric surgery procedures, frequently the only treatment for patients with life-threatening obesity.
Objective: The aim of this study was to verify if the exposure to the pulsed electromagnetic field (PEMF) infl uenced the release of proinfl ammatory cytokines from adipose-derived stem cells (ADSCs) of normal and overweight rats of various age and sex. Moreover, we compared body temperatures of normal-weight and overweight rats.
Methods: ADSCs of Wistar rats were isolated from the subcutaneous area in females and paratesticular region in males, cultured and exposed to PEMF (7 Hz, 30 mT). Concentrations of proinflammatory cytokines were determined in rat sera and supernatant from ADSCs cultures exposed and non-exposed to PEMF. Body temperature (BT) was measured twice a week, using an infrared and rectal thermometer.
Results: Irrespective of age and sex, animals maintained on low-fat (LF) diet had higher BT than those grown on high-fat (HF) diet. Exposure to PEMF reduced the release of TNF-α and enhanced the production of IL-6 in ADSCs cultures from female pups maintained on LF diet. In contrast, a decrease in IL-6 level was observed in PEMF-exposed ADSCs cultures from female pups grown on HF diet. A similar phenomenon, i.e. a post-exposure increase in IL-6 level was also observed in male pups fed with the LF diet. In the case of ADSCs cultures from adult rats maintained on an HF diet, either males or females, PEMF exposure contributed to a dramatic increase in TNF-α production.
Conclusion: Our findings suggest that PEMF exposure may affect the production of proinflammatory cytokines in ADSCs cultures. The intergroup diff erences in BT may result from the presence of an underlying inflammation in obese rats.
How is formed the adjective fettleibig (obese)? It may seem an evident derivate from fett (fat) and Leib
(body); however, the NP fetter Leib is as seldom as the adjective is frequent: this sounds paradoxical.
In this contribution, a new way of explaining the formation of this adjective is explored: fettleibig
appears as a subsistance of a in past times rich -leibig-paradigm. Therefore, in a synchronic view, this
adjective is not explained as a derivate, although it remains mainly transparent.
The study was undertaken to determine the effect of continuation or changes of the diet on the morphometry and histomorphometry of bone in male and female Wistar rats with experimen- tally induced obesity by high energetic diet. Sixty-four 90-day-old Wistar rats obtained from obese parents (16 male, 16 female) and control parents (16 male, 16 female) were used in this study. After 21 days of the baby period, rats were divided into four groups: obese rats fed with high energy feed (F/F), control rats fed with a standard diet (C/C), obese rats with changed diet from high energy diet to control diet (F/C) and control rats with changed diet from control diet to high energy diet (C/F). After 90 days of experimental feeding, the rats were sacrificed. Thereafter, body weight and the isolated humerus were measured and next, the histological stainings and counts were done. Our results revealed that change in the parent’s diet from F to C in the female leads to increased bone growth length and reduction of body weight in female and male. Reverse diet changes (from C to F) lead to decreased bone length only in the female. Moreover, the con- tinuation by offspring of both sexes with a high-energy diet contributes to a reduction in osteo- cytes, reduction in bone marrow cavity and cortical expansion, but a change in nutrition from parents’ standard diet to high-energy diet leads to increase in osteocytes dimensions. The contin- uation of feeding with F diet promotes the accumulation of adipocytes in the bone marrow in female and male, and correction of nutrition from F to standard diet leads to a reduction in their number in the bone marrow compared to groups continuing feeding with high-energy diet.
