    Abstract: Platostoma palustre jelly is a traditional food. Platostoma palustre has been used as folk medicine and is effective against heat-shock, hypertension and diabetes. Therefore, the aim of in vivo study was to determine the effects of herbal tea (Platostoma palustre) on blood glucose regulation. The commercial herbal tea (Platostoma palustre) was kindly provided by Yueta Agricultural Biotechnology Inc. Adult male 18 Institute of Cancer Research (ICR) mice [8 weeks old; body weight (BW) between 31-33 g] with specific pathogen-free conditions were used for this study. All ICR mice were divided respectively the normal control group (n = 6), the negative control group (n = 6), and the herbal tea group (n = 6). The ICR mice (the negative control group and the herbal tea group) were intraperitoneally injected with streptozotocin (65 mg/kg BW) and nicotinamide (230 mg/kg BW) for inducing the symptoms of hyperglycemia. In the herbal tea group, the herbal tea (10 mL/kg BW) was administrated to ICR mice by gavage. To monitor the blood glucose levels in ICR mice, blood was obtained from the tail of ICR mice, and blood glucose levels were determined using the external glucometer. Blood glucose measurements were conducted once in ICR mice before the experiment and were detected once per month after the experiment. Additionally, the change of ICR mice’ BW, the blood glucose of ICR mice, and the observation of ICR mice’ behavior were monitored and detected during the experiment. The results of this experiment showed · Weight change: the weight gain of the negative control group and the herbal tea group were significantly lower than those of the normal control group and there was no significant difference between the negative control group and the herbal tea group. · Fasting blood glucose and postprandial blood glucose: the fasting blood glucose of the negative control group was significantly higher than that of the normal control group, while the herbal tea group had a tendency to lower the fasting blood glucose, but there was no significant difference compared with the negative control group. The postprandial blood glucose level results showed that the negative control group was significantly higher than the normal control group. The postprandial blood glucose level of the herbal tea group was between the normal control group and the negative control group at the 4th week administration with the herbal tea. At the 8th week administration with the herbal tea, there was a significant difference compared with the negative control group. · Oral glucose tolerance test (OGTT): 4 to 12 weeks after hyperglycemia was induced, the blood glucose levels of the negative control group at each OGTT test point were significantly higher than those of the normal control group. The blood glucose level at the test point tended to decrease, but there was no significant difference from the negative control group. By calculating the area under the OGTT curve, it was found that the area under the curve of the negative control group was significantly higher than that of the normal control group, while the results of the herbal tea group at the 8th and 12th weeks were significantly lower than those of the negative control group. Taken all results together, the hyperglycemia was successfully induced in the experimental ICR mice. After administrating with the herbal tea, the fasting blood glucose level of the ICR mice tended to improve. In addition, a significant improvement was seen in the results of postprandial blood sugar and oral glucose tolerance test effectiveness. Therefore, based on the results of this experiment, it is speculated that drinking the herbal tea for 3 months has considerable potential for blood glucose regulation, which can be used as the basis for the development of related products of the herbal tea in the future.

    Abstract: Platostoma palustre (Pp) jelly is a traditional food. Pp has been used as folk medicine and is effective against heat-shock, hypertension and diabetes. Therefore, the aim of this study was to evaluate the ethanolic extracts of Pp’ genotoxicity. The ethanolic extracts of Pp by using 40% ethanol for extraction. Evaluation of genotoxicity of ethanolic extracts of Pp by micronucleus assay was performed in vivo. During the in vivo genotoxicity-evaluated experiment, the experimental animal’s clinical behavior, body weight (BW), food consumption, and the percentage of RET/RBCs (reticulocytes/red blood cells) and MN-RET/RETs (micronucleated reticulocytes/reticulocytes) after the treatments of Pp ethanolic extracts were evaluated. Both sexes Institute of Cancer Research (ICR) mice were given three daily treatments by intraperitoneal injection of 2 mg/kg of mitomycin C (genotoxicity induction) or by oral route of 200 μL of PBS (normal control group). Until 48 h after the last treatment, K2-EDTA-anticoagulated peripheral blood specimens were collected. These blood samples were processed for the microscopy-based analysis using Giemsa stain and the percentage of reticulocytes and micronucleated reticulocytes was determined. The results were shown that the experimental animal’s clinical behaviors were normal in all groups. The BW and food consumption were no significant difference between all groups. RET/RBCs (‰) in male or female ICR mice in the negative control group, the normal control group, the high dose of Pp ethanolic extract group, the middle dose of Pp ethanolic extract group, and the low dose of Pp ethanolic extract group were respectively 7.8 ± 0.8 / 8.6 ± 0.8, 23.2 ± 1.5 / 22.1 ± 1.3, 22.8 ± 1.6 / 22.1 ± 1.7, 23.2 ± 1.5 / 22.6 ± 1.0 and 22.2 ± 1.9 / 23.9 ± 1.9; MN-RET/RETs (‰) in male or female ICR mice in the negative control group, the normal control group, the high dose of Pp ethanolic extract group, the middle dose of Pp ethanolic extract group, and the low dose of Pp ethanolic extract group were 2.0 ± 0.0 / 2.0 ± 0.0, 43.2 ± 10.6 / 39.6 ± 10.9, 1.8 ± 0.4 / 1.6 ± 0.5, 1.6 ± 0.5 / 1.4 ± 0.5, and 1.8 ± 0.4 / 1.6 ± 0.5, respectively. Both RET/RBCs (‰) and MN-RET/RETs (‰) in male or female ICR mice in the negative control group were significantly difference than the other groups (p 〈 0.001). Taken all results together, Pp ethanolic extracts were without genotoxicity. Therefore, Pp ethanolic extracts were safety.

    Abstract: Platostoma palustre jelly is a traditional food. Platostoma palustre has been used as folk medicine and is effective against heat-shock, hypertension and diabetes. Therefore, the aim of this study was to determine the effects of ethanolic extracts and commercial herbal tea of Platostoma palustre in inhibiting colorectal cancer cell viability. The ethanolic extracts of Platostoma palustre by using 90% ethanol for extraction. In this study, 2-fold serial dilution of 100 mg/mL Platostoma palustre extracts were applied. On other hand, the same dilution fold was also performed for 100% commercial herbal tea with Platostoma palustre. Additionally, CT-26 and HT-29 colorectal cancer cell lines were also used in this study. After co-culturing for 24 hours, the cell viability of CT-26 and HT-29 colorectal cancer cell lines were performed by using 3-(4, 5-Dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay. According to these data, the 1.56-100 mg/mL Platostoma palustre extracts possessed the significant inhibition effects of CT-26 colorectal cancer cell viability. The 3.13-100% commercial herbal tea with Platostoma palustre possessed the significant inhibition effects of CT-26 colorectal cancer cell viability. The 6.25-100 mg/mL Platostoma palustre extracts possessed the significant inhibition effects of HT-29 colorectal cancer cell viability. The 25-100% commercial herbal tea with Platostoma palustre possessed the significant inhibition effects of HT-29 colorectal cancer cell viability. However, the 0.39-3.13 mg/mL Platostoma palustre extracts possessed the significant promoting effects of HT-29 colorectal cancer cell viability. The 0.39-12.5% commercial herbal tea with Platostoma palustre also possessed the significant promoting effects of HT-29 colorectal cancer cell viability. Comparison of CT-26 and HT-29 cell lines was on the cell viability after Platostoma palustre ethanolic extracts and commercial herbal tea treatments, CT-26 cell line was better sensitive than HT-29 cell line on the inhibition of cell viability after treatment of Platostoma palustre ethanolic extracts and the commercial herbal tea. Taken these results together, Platostoma palustre ethanolic extracts and commercial herbal tea may have a potential for inhibiting the growth of colorectal cancer cells.

    Abstract: Many studies have been verified that human retina contains a large amount of carotenoids such as lutein and zeaxanthin, especially the concentrations of lutein and zeaxanthin in the retina and macula are 1,000 times higher than other tissues in human. Therefore, lutein and zeaxanthin play an important role in the health of human vision. The research and development (R & D) of agricultural functional materials or products for eye protection is urgently needed. In this experiment, except for the normal control group, the other groups were irradiated with light-emitting diode (LED) light at the range of 600-1,000 lux for 12 hours / day for 6 weeks. All BALB/c mice were fed with the normal composition for 6 weeks during the experiment. BALB/c mice in the negative control group and three sweet potato leaf ethanolic extracts (SPLEE) groups were fed SPLEE [0.31, 0.62, and 1.23 mg/kg body weight (BW), respectively] for 6 weeks by gavage during the experiment. During the experiment, the eye status of BALB/c mice in each group were observed every week. At the end of the experiment, the BALB/c mice were sacrificed and their eyes in each group were collected for hematoxylin & eosin (H & E) staining, immunohistochemical (IHC) staining, free radical detection, and the detection of cytokine gene expressions (IL-6; interleukin-6 and TNF-α; tumor necrosis factor-α) and caspase-3 gene expression. Based on the results of this experiment, no obvious lesions by ophthalmoscopy were observed in the eyes of BALB/c mice in three SPLEE groups. H & E and IHC staining results showed that the consumption of high dose (1.23 mg/kg BW) of SPLEE significantly improved retinal outer nuclear layer (ONL) thickness, which was compared to the negative control group. Other evaluation indicators included retinal out segments-inner segments (OS/IS) thickness, glial fibrillary acidic protein (GFAP) staining, and middle-wavelength opsin (M-opsin) staining, showed no significant difference among three SPLEE groups and the negative control group. The free radical detection results showed that no statistical difference between all groups (p 〉 0.05), however, the trend showed that the free radicals in the high and middle doses (1.23 and 0.62 mg/kg BW) of SPLEE groups were lower than those in the negative control group and the low dose (0.31 mg/kg BW) of SPLEE group. The results of IL-6 and TNF-α gene expression showed that the normal control group and three SPLEE groups were significantly lower than the negative control group (p 〈 0.05), while the gene expression of caspase-3 was not significantly differences between all groups (p 〉 0.05). Taken these results together, the high dose SPLEE (1.23 mg/kg BW) has the better potential for improving the retinal ONL thickness and anti-inflammatory effects under LED irradiation.
