Multiple beneficial properties of Opuntia ficus indica (OPF) are well established. In the present study, we have investigated the immunological role of OPF extract (OPFE) on murine splenocytes. OPFE dose- and time-dependently enhanced the proliferation of splenocytes without cytotoxicity. Our results also showed that the number of $CD4^+$ helper T cells and CD45R/$B220^+$ pan B cells increased markedly, but not $CD8^+$ cytotoxic T cells or $CD11b^+$ granulocytes/macrophages. In addition, OPFE significantly decreased the production levels of T helper (Th) 1 type cytokines, interferon (IFN)-$\gamma$, and tumor necrosis factor (TNF)-$\alpha$, although had no significantly differences in those of interleukin (IL)-4, a Th2 type cytokine in concanavalin A (Con A)-stimulated blastogenic cells. Furthermore, OPFE alone strongly increased IL-4 production and decreased TNF-$\alpha$ production even in the absence of Con A. On the basis of these results, this study suggests that OPFE enhances immunity by regulating the pro- and anti-inflammatory response, indicating that this extract exerts a marked immunomodulatory effect, confirming its usefulness as therapy for immune-related diseases.

A feeding trial was conducted to investigate the effects of dietary carotenoids sources on growth and skin color of red- and white-colored fancy carp Cyprinus carpio var. koi. Nine experimental diets (designated as Con, CP, PA, SP, OP, MB, TO, BE and PO) were formulated to contain Carophyll Pink, red paprika, Spirulina, Opuntia, mandarin bark, tomato, beet and Porphyra, respectively. Each experimental diet was fed to two replicate groups of fish (22.9 g/fish) to visual satiation three times a day for 8 weeks. Weight gain and feed efficiency of fish fed the diets containing Spirulina or Opuntia were higher than those of fish fed the control diet (P<0.05). The values of $a^*$, $L^*$ and $b^*$ of fish skin were significantly changed by dietary carotenoids sources (P<0.05). The $a^*$ values of fish fed the diets containing Carophyll Pink, red paprika and Spirulina were higher than those of fish fed other diets (P<0.05). The skin total carotenoids of fish fed the diets containing Spirulina and Opuntia were higher than those of others (P>0.05). Based on the results of this study, it can be concluded that dietary inclusion of red paprika and Spirulina pacifica could increase the skin redness of red- and white-colored fancy carp.

In this study, the Opuntia humifusa f. jeollaensis (Wanggasi-Chunnyuncho) fruit (WCF) was used as a source of viscous dietary fiber and color pigmentation in sausage production to improve quality characteristics, including cooking loss and emulsion stability. Control and treatment sausages were formulated with 0%, 1%, 5%, and 10% WCF powder, respectively, and the following quality measures were investigated: general composition, fiber content, cooking loss, emulsion stability, chromaticity, pH, texture, and sensory properties. The moisture, dietary fiber, and ash contents showed increasing trends (all p<0.05) with increasing concentrations of fruit powder. Conversely, crude protein and crude fat contents exhibited decreasing trends with increasing fruit powder concentrations (p<0.05). Moreover, both the moisture and dietary fiber contents affected cooking loss, water retention capacity, and the sausage texture, causing the cooking loss to decrease, while the water and oil retention capacity increased (p<0.05) with increasing concentrations of WCF powder. Furthermore, hardness exhibited a significant decreasing trend as the concentration of WCF powder increased (p<0.05). This finding suggested that both dietary fiber and viscous materials, along with the protein and moisture content, affected the product hardness. In addition, sensory evaluation of the WCF powder groups showed better results than did the control group, and the strongest results obtained for the group containing 5% fruit powder (p<0.05). Therefore, this study suggests that WCF powder improves the quality of emulsified sausages and can potentially be applied as a naturally-derived additive.

Opuntia humifusa contains high levels of antioxidants including vitamin C, flavonoids and polyphenols, which may provide beneficial effects such as hypolipidemic activity and the reduction of atherosclerosis in postmenopausal women. This study was conducted to determine if the intake of O. humifusa seeds powder (OHS) regulates lipid concentrations, glutamate-oxaloacetate transaminase (GOT), and glutamate-pyruvate transaminase (GPT) in the serum of ovariectomized rats. Sprague-Dawley female rats were randomly assigned to either a sham-operated group (Sham) or one of the following four ovariectomy (OVX) subgroups: OVX with vehicle (OVX), OVX with 100, 200, and 500 mg/kg/day OHS (OHS100, OHS200, OHS500). Daily oral administration of OHS was initiated one week after ovariectomy and continued for seven weeks. Upon completion of treatments, organs were weighed and GOT, GPT, total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) levels were determined enzymatically. No significant differences in feed intake and organ index were observed among the groups. Significant decreases in GPT, TC and LDL-C (p<0.05) were observed in all of the OHS groups (OHS100, 200 and 500), while no significant changes in HDL-C were observed. In addition, the OHS200 and OHS500 treatment groups exhibited a lower level of serum GOT compared to the OVX group. These results indicate that supplementation with O. humifusa seeds could induce favorable changes in serum lipoprotein and lipid profiles, which frequently worsen with inadequate estrogen availability.

BACKGROUND/OBJECTIVES: Obesity, characterized by abnormal fat accumulation and metabolic disturbances, presents a significant health challenge. Opuntia humifusa Raf., commonly known as Korean Cheonnyuncho, is rich in various beneficial compounds and has demonstrated antioxidant and anti-inflammatory effects. However, its potential impact on glucose and lipid metabolism, particularly in obese rats, remains unexplored. We aimed to investigate whether O. humifusa stems and fruits could beneficially alter glucose metabolism and lipid profiles in a rat model of high-fat diet (HFD)-induced obesity. MATERIALS/METHODS: Thirty-two rats were allocated into 4 groups: normal diet (NF), HFD control (HF), HFD treated with 2% O. humifusa stems (HF-OS), and HFD treated with 2% O. humifusa fruits (HF-OF). Experimental diets were administered for 6 weeks. At the end of the treatment, liver and fat tissues were isolated, and serum was collected for biochemical analysis. The major flavonoid from O. humifusa stems and fruits was identified and quantified. RESULTS: After 6 weeks of treatment, the serum fasting glucose concentration in the HF-OS group was significantly lower than that in the HF group. Serum fasting insulin concentrations in both HF-OS and HF-OF groups tended to be lower than those in the HF group, indicating a significant improvement in insulin sensitivity in the HF-OS group. Additionally, the HF-OS group exhibited a tendency towards the restoration of adiponectin levels to that of the NF group. CONCLUSION: The 2% O. humifusa stems contain abundant quercetin and isorhamnetin, which alter fasting blood glucose levels in rats fed a HFD, leading to a favorable improvement in insulin resistance.

손바닥선인장의 한 종류인 노팔(Opuntia ficus-indica (L.) Mill)을 주재료로 하여 제조한 복합물(OF)의 항당뇨 효과를 알아보기 위해 8주령 수컷 SD-rat에게 streptozotoxin을 주사하여 당뇨를 유발하고, 사료에 OF를 첨가하여 3주간 급여하였으며, 1주일 간격으로 공복 시 혈당을, 3주 후에는 당내성과 혈장 인슐린 농도를 측정하고 췌장 조직에 면역조직화학 염색을 실시하였다. 실험동물은 정상 대조군(NC), 당뇨 대조군(DC), 2% OF 급여군(OF-2), 5% OF 급여군(OF-5)으로 구분되었으며, NC와 DC는 기초식이를, OF-2와 OF-5는 기초식이에 각각 2%와 5%의 OF를 섞어서 급여하였다. 실험 개시 후 1주마다 12시간 절식시켜 꼬리정맥에서 혈액을 채취하여 공복 혈당을 측정하였다. 실험 3주 후 12시간을 절식시켜 glucose(50 mg/kg BW)를 복강주사한 다음, 30, 60, 90, 120분 경과 후에 혈당을 측정하여 당내성을 측정하였고, 심장에서 혈액을 채취하여 혈중 인슐린 함량을 분석하였다. 또한 췌장 조직에 대해 면역조직화학 염색을 실시하여 조직학적인 변화를 알아보았다. 3주간의 공복 시 혈당은 OF-5와 OF-2 모두 유의적으로 감소하였다(p<0.05). 당내성 측정 결과, OF 급여군은 DC와는 달리 혈당 농도의 변화 추이가 NC와 유사하였으며, 특히 OF-5는 OF-2에 비해서도 혈당 강하 효과가 높았던 것으로 드러났다. 췌장 조직의 면역염색에 의하면, OF의 혈당강하 기작은 췌장 Langerhans' Islet의 ${\beta}$-세포를 생성시키고, ${\beta}$-세포의 사멸을 억제시켜 인슐린의 분비를 정상화시키는 것이었으며, 이러한 결과는 혈장 인슐린 함량의 증가로 재확인할 수 있었다. 결론적으로 OF는 I형 당뇨에서 현저한 혈당 강하 효과 및 Langerhans' Islet의 ${\beta}$-세포수를 회복시켜줌으로써 I형 당뇨의 치료에 효과가 있을 것으로 사료된다.

천년초(Opuntia humifusa)에 존재하는 점질다당의 새로운 이용방안을 모색하기 위해 천년초로부터 다당을 분리하여 면역자극활성을 측정하였다. 천년초의 주요 다당 CNC-E는 상업용 효소처리, 물 추출 및 ethanol 침전을 거쳐 조제하고 이들의 특성을 검토하였다. CNC-E는 분자량 약 700 kDa의 다당체로, 구성당 조성을 확인한 결과, arabinose, galactose 및 xylose를 높은 비율로 함유하고 있었으며 rhamnose와 fucose를 미량 함유하고 있었다. 한편 CNC-E는 비장세포 유래 림프구에 대해서는 비교적 높은 증식활성을 농도 의존적으로 나타냈다. CNC-E로 자극한 macrophage는 IL-6, IL-12, IL-10 및 TNF-${\alpha}$와 같은 cytokine의 생산을 농도 의존적으로 증진시켰으며 CNC-E를 mouse에 정맥 주사한 후 얻어진 NK세포는 Yac-1 종양 세포주에 대한 높은 치사작용을 보였다. 특히 CNC-E를 mouse 당 $100{\mu}g$ 처리한 후 얻어진 NK세포는 미처리 대조군에 비해 3배 높은 치사활성을 나타냈다. CNC-E는 인체 초기 면역반응에 있어 중요한 역할을 담당하는 보체계에 대하여 농도 의존적인 활성을 나타냈으며, anti-human C3를 이용한 면역전기영동실험과 $Ca^{2+}$이온이 제거된 상태에서의 항보체 활성 실험을 통해 천년초 다당 CNC-E는 고전경로와 부경로를 모두 경유하여 활성을 나타내고 있음을 확인하였다. 이상의 결과로부터 한국산 선인장 천년초에는 인체에 유익한 면역 활성 다당체를 다량 함유함을 알 수 있었다.
