        다이어트젤과 전기근육자극기가 허리둘레 감소에 미치는 영향

        이광희(Gwang-Hee Lee) 한국응용과학기술학회 (구.한국유화학회) 2021 한국응용과학기술학회지 Vol.38 No.2

        바쁜 일상 속에서 신체 활동량의 감소와 식생활의 서구화 등으로 인한 복부 비만의 발생률이 높아지고 있다. 따라서 체형 관리에 대한 욕구를 충족시키기 위해 시간 대비 고 효율의 관리 프로그램이 필요하다. 본 연구에서는 전기근육자극요법 (electric muscle stimulation therapy)을 활용하여 다이어트젤 (슬리밍 화장품)과의 복합사용에 의하여 허리둘레 및 체지방량 (또는 복부의 지방)를 감소 효과를 촉진시켰 다. 연구 대상자는 20대 성인 남녀로 다이어트젤을 허리 부위에 단순 도포를 한 후, 그 위에 EMS를 착용 하여 기상 후와 취침 전에 1일 2회 20분간 마사지를 실시하였다. 실험 기간은 2주 동안 실시되었다. 지방 분해 촉진 효과는 비 조영 CT를 활용하여 피하지방의 감소에 대한 관찰이 되었으며, 이와 함께 허리둘레와 체지방량 측정으로 확인되었다. 결론적으로 개발된 EMS와 다이어트젤의 동시 사용 프로그램은 약 3 cm (p<.001)의 허리둘레 감소와 약 1 kg (p<.01)의 체지방량 감소를 나타내어 허리라인 관리에 탁월한 효과가 있음을 입증하였다. 이는 EMS의 활용이 근육 자극에 의한 마사지 효과를 나타내며 다이어트젤의 흡수를 도와 지방 분해를 촉진시키는 역할을 하는 것으로 사료된다. Abdominal obesity is increasing due to a decrease in physical activity and westernization of diet in busy daily life. Therefore, in order to satisfy the desire for body shape management, a management program with high efficiency versus time is needed. In this study, the diet-gel (i.e., slimming cosmetics) with the electrical muscle stimulation therapy was used to promote the effect of reducing waist circumference and body fat mass (or abdominal fat). For men and women in their twenties, the subjects simply applied diet-gel to their waist, wore EMS, and massaged for 20 minutes twice a day after waking up and before going to sleep. The experiment period was carried out for 2 weeks. The reduction of subcutaneous fat was observed using non-contrast CT, and it was confirmed by measuring waist circumference and body fat mass. In conclusion, the developed EMS and diet-gel combination program showed excellent waist management effects by reducing waist circumference by about 3 cm (p<0.001) and body fat mass by about 1 kg (p<0.01). This result suggests that the use of EMS shows a massage effect by muscle stimulation, and plays a role in promoting fat decomposition by helping the absorption of diet gel.

      • Dietary Aloe Vera Gel Powder and Extract Inhibit Azoxymethane-induced Colorectal Aberrant Crypt Foci in Mice Fed a High-fat Diet

        Aloe vera gel exhibits protective effects against insulin resistance as well as lipid-lowering and anti-diabetic effects. The anti-diabetic compounds in this gel were identified as Aloe-sterols. Aloe vera gel extract (AVGE) containing Aloe-sterols has recently been produced using a new procedure. We previously reported that AVGE reduced large-sized intestinal polyps in Apc-deficient Min mice fed a high fat diet (HFD), suggesting that Aloe vera gel may protect against colorectal cancer. In the present study, we examined the effects of Aloe vera gel powder (AVGP) and AVGE on azoxymethane-induced colorectal preneoplastic aberrant crypt foci (ACF) in mice fed a HFD. Male C57BL/6J mice were given a normal diet (ND), HFD, HFD containing 0.5% carboxymethyl cellulose solution, which was used as a solvent for AVGE (HFDC), HFD containing 3% or 1% AVGP, and HFDC containing 0.0125% (H-) or 0.00375% (L-) AVGE. The number of ACF was significantly lower in mice given 3% AVGP and H-AVGE than in those given HFD or HFDC alone. Moreover, 3% AVGP, H-AVGE and L-AVGE significantly decreased the mean Ki-67 labeling index, assessed as a measure of cell proliferation in the colonic mucosa. In addition, hepatic phase II enzyme glutathione S-transferase mRNA levels were higher in the H-AVGE group than in the HFDC group. These results suggest that both AVGP and AVGE may have chemopreventive effects on colorectal carcinogenesis under the HFD condition. Furthermore, the concentration of Aloe-sterols was similar between 3% AVGP and H-AVGE, suggesting that Aloe-sterols were the main active ingredients in this experiment.
