Optimizing <i>Canang</i> Flower Waste Extract for Staining <i>Fasciolopsis buski</i> Eggs: An Enhancement of the Kato-Katz Method

Pain is the most common complaints in everyday practice. Pain is a clinical manifestation caused by stimuli due to potential tissue damage. Low level laser therapy (LLLT) has been used in reducing pain. One of indicator tissue healing is activation of transforming growth factor -b1(TGF-b1). Tissue healing will eliminate the pain. Do LLLT stimulate TGF-b1 expression? The objective of this study was to investigate the expression of TGF-b1 in low level laser therapy. Thirty male Wistar rats, body weight 250 – 300 gram, 3 month old, were divided into 3 groups, negative control (n=10), positive control (n=10) and treatment groups (n=10). The positive control and treatment groups were injected with Complete’s Freund Adjuvant (CFA) 100 mL at left footpad. The treatment group treated with low level laser therapy Lasermed type 2100 wavelength 905 nm, out power 25-500 mW, dose 1 joule/cm2;5 times with interval 24 hours on left footpad. Samples were taken from the skin of footpad and immunohistochemical examination with monoclonal antibody anti- TGF-b1. Calculations carried out on brown reaction in macrophage cell. Data were analyzed using the Games Howell with SPSS 17. There were significant differences in the expression of TGF-b1 in treatment group (15.8±3.1) compared with the positive control group (3.9±1.1) and negative control group (4.6±2.1). There were no significant differences between expression TGF-b1 in positive control group and negative control group. In conclusion, low level laser therapy increased the expression of TGF-b1.

Objective To explore the expressions of phosphatidylinositol 3-kinase p85(PI3Kp85) and protein kinase B(Akt) in nude mice model of human hemangioma xenograft and examine the role of PI3K/Akt signaling pathway in evolution process of hemangioma in children. Methods The surgical specimens of proliferating hemangioma were harvested from a male 3-month-old infant. The tissues were sliced into small pieces 5 mm 4 mm 3 mm in size and grafted subcutaneously into nude mice. After growing for 45 days, a total of 48 cases of successful xenograft specimens were randomized into 3 groups: 0.05 ml saline was intratumorally injected for each tumor in control group, 0.05 ml insulin-like growth factor(0.5 μmol/L)intratumorally injected for each tumor in positive control group and 0.05 ml LY294002(25 μmol/L)was intratumorally injected for each tumor in negative control group. At the day of injection and 3 days, 1 week and 2 weeks post-injection, the morphological changes of hemangioma xenografts were visually observed and their structural changes observed microscopically. The expressions of PI3Kp85, p-Akt protein were determined by immunohistochemistry. And the expressions of PI3Kp85 mRNA and p-Aktm RNA were observed by reverse transcription-polymerase chain reaction(RT-PCR). Results The positive expression rates of PI3Kp85 and p-Akt were 100% in control and positive control groups. And the positive expression rates were 80.00% and 86.67% in negative control group. The stains of PI3Kp85 and p-Akt became weaker significantly in negative control group. And significant differences in PI3Kp85 and p-Akt stains existed between negative control and control groups(P<0.05 or 0.01) and then xenograft specimens showed regression. The stains of PI3Kp85 and p-Akt turned stronger significantly in positive control group. Significant differences of PI3Kp85 and p-Akt stains existed between positive control and control groups(P<0.05 or 0.01). The xenograft specimens showed proliferation. And the expression levels of PI3Kp85 and p-Akt had positive correlations. Conclusions PI3K/Akt signal pathway is probably participating in regulating the apoptosis of hemangioma endothelial cells in nude mice model with human hemangioma xenograft. And LY294002 and insulin-like growth factor may induce tumor regression and proliferation by intervening the corresponding targets in PI3K/Akt signaling pathway.

Mummy was used in traditional medicine as a remedy for inflammation, articular injuries, rheumatism, bone fractures, wounds and back pains. In previous research, the healing effects of mummy on a rabbit’s tibial fracture were studied, and the results supported its efficacy. In consideration of claims and suggestions by traditional medicine about the effectiveness of mummy on wound healing, the present study was aimed at investigating the protective effect of mummy on gastric ulcer induced by ethanol. Young male albino rats (NMRI strain, n = 21, 190–230 g body weight) were randomly divided into three experimental groups: treatment group, positive control group and negative control group, each containing seven rats. All animals had been exposed to starvation for 24 h and then received oral ethanol (1 ml/200 g body weight). The treatment group received 100 mg/kg/day mummy; the positive control group received 200 mg/kg/day cimethidine, and the negative control group received 5 ml/kg/day distilled water for 2 weeks by gavages. One hour after the last treatment, all animals were killed, and their stomachs were dissected. The number and length of ulcers were determined using stereomicroscope; then graticule and the ulcer index and curative ratio were calculated. Data was analysed using one-way ANOVA and Tukey’s post hoc test. The administration of mummy significantly decreased the gastric ulcer score and ulcer index in the treatment group, compared with the positive control and negative control groups. The curative ratio in the treatment group was significantly higher than the negative control and the positive control groups (89.26 versus 87.79 %, respectively). The results showed excellent effects of mummy on wound healing after the ethanol-induced gastric ulcer in rats.

Objective To observe the preventive effect of Hirudoid (MPS) ointment on psoriasis-like dermatitis in mice and explore its mechanism. Methods 21 Balb/C mice were randomly divided into three groups: blank control group, positive control group (imiquimod group) and treatment group (imiquimod+ Hirudoid group). The blank control group was treated with imiquimod matrix. The positive control group was treated with 5% imiquimod cream to induce psoriatic dermatitis in mice′s back. The treatment group was treated with 5% imiquimod cream in the morning and Hirudoid cream in the afternoon. The changes of skin erythema, scales , infiltration severity and skin histopathology in the experimental area of mice back and serum levels of interleukin (IL)-17A and protein expression of tumor necrosis factor-α (TNF-α) in the three groups of mice were observed. Results The clinical and pathological findings of skin lesions in the positive control group showed that 5% imiquimod cream successfully induced psoriasis-like dermatitis in mice. The appearance and pathological feature of skin lesions in the blank control group were almost close to normal skin. The degree of erythema, infiltration and scales in the back of the treatment group was significantly less than that in the positive control group, and the degree of microscopic inflammation in the treatment group was also lighter than that in the positive control group; The serum levels of IL-17A and TNF-α in the treatment group and the blank control group were significantly lower than that of the positive control group, with statistically significant difference (P<0.05). Conclusions Hirudoid can significantly reduce imiquimod-induced psoriasis-like dermatitis by inhibiting the expression of IL-17A and TNF-α. Key words: Psoriasis; Glycosaminoglycans; Mice

To discuss the expression of glactin-3 in liver metastasis of colon cancer and its inhibition by modified citrus pectin (MCP) in mice. Seventy-five Balb/c mice were randomly divided into negative control group (n = 15), positive control group (n = 15), low MCP concentration group (n = 15), middle MCP concentration group (n = 15) and high MCP concentration group (n = 15). CT26 colon cancer cells were injected into the subcapsule of mouse spleen in positive control group, low, middle and high MCP concentrations groups, except in negative control, to set up a colon cancer liver metastasis model. The concentration of MCP in drinking water was 0.0%, 0.0%, 1.0%, 2.5% and 5.0% (wt/vol), respectively. Liver metastasis of colon cancer was observed after 3 wk. Enzyme-linked immunosorbent assay (ELISA) was used to detect the concentration of galectin-3 in serum. Expression of galectin-3 in liver metastasis was detected by immunohistochemistry. Except for the negative group, the percentage of liver metastasis in the other 4 groups was 100%, 80%, 73.3% and 60%, respectively. The number of liver metastases in high MCP concentration group was significantly less than that in positive control group (P = 0.008). Except for the negative group, the median volume of implanted spleen tumor in the other 4 groups was 1.51 cm(3), 0.93 cm(3), 0.77 cm(3) and 0.70 cm(3), respectively. The volume of implanted tumor in middle and high MCP concentration groups was significantly smaller than that in positive control group (P = 0.019; P = 0.003). The concentration of serum galectin-3 in positive control and MCP treatment groups was significantly higher than that in the negative control group. However, there was no significant difference between them. Except for the negative control group, the expression of galectin-3 in liver metastases of the other 4 groups showed no significant difference. Expression of galetin-3 increases significantly in liver metastasis of colon cancer, which can be effectively inhibited by MCP.

Objective: To study the effect of particulate matter 2.5 (PM(2.5)) on oncogene expression in human bronchial epithelial (HBE) cells. Methods: HBE cells were selected as the study subjects, and PM(2.5) treatment group (10 μg/ml and 50 μg/ml) , negative control group and positive control group (10 μmol/L Cr(6+)) were set. CCK8 assay was used to test the IC(50) value of PM(2.5). HBE cells were treated with PM(2.5) for 24 h at 10 μg/ml and 50 μg/ml, additionally, cells were treated with blank as negative control, 10 μmol/L Cr(6+) as a positive control for 24 h. After the treatment, mRNA expression of oncogenes including c-myc, c-fos, k-ras and p53 were detected by fluorescent quantitative RT-PCR, the protein expression of oncogenes were detected with western blot. Results: The IC(50) value of PM(2.5) in HBE cells is 70.12 μg/ml. The qRT-PCR data showed that compared with the control group, the expression level of c-myc gene increased by respectively 500.1%、780.7%、305.3% after exposure to 10、50 μg/ml PM(2.5) and positive control group; c-fos gene increased respectively 34.0%、76.7%、131.3% after exposure to 10、50 μg/ml PM(2.5) and positive control group; k-ras gene increased respectively 50.3%、107.0%、49.7% after exposure to 10、50 μg/ml PM(2.5) and positive control group; p53 gene decreased by 28.3%、28.7%、59.7% after exposure to 10、50 μg/ml PM(2.5) and positive control group. The western blot results showed that compared with the control group, c-myc protein increased respectively 29.7%、77.3% after exposure to 50 μg/ml PM(2.5) and positive control group; c-fos protein increased respectively 200.3%、137.0% after exposure to 50 μg/ml PM(2.5) and positive control group; k-ras protein increased respectively 106.3%、130.3%、116.7% after exposure to 10、50 μg/ml PM(2.5) and positive control group; p53 protein decreased by 43.7%、53.3%、52.1% after exposure to 10、50 μg/ml PM(2.5) and positive control group.

Platynosomiasis is a parasitic infection reported in non-human primates, including marmosets, and is frequently difficult to diagnose. In this study, the Kato-Katz method and the spontaneous sedimentation method were evaluated for their usefulness in identifying Platynosomum eggs in fecal samples from Callithrix penicillata that naturally harbor Platynosomum illiciens. Spontaneous sedimentation allowed the diagnosis of 41.7% (5/12) and 66.7% (8/12) of infected marmosets from one and three slides, respectively, prepared from the same fecal sample. The examination of a single Kato-Katz thick smear detected 83.3% (10/12) of infection cases. The analysis of feces on three different days increased the rate of diagnosis, since 75% (9/12) and 100% (12/12) of the primates with platynosomiasis were identified using serial spontaneous sedimentation (3 slides/day) and the Kato-Katz method, respectively. The mean number of Platynosomum eggs per gram of feces determined via the Kato-Katz method was 71.7 (8-240). The spontaneous sedimentation method when performed in series is acceptable for the diagnosis of platynosomiasis. However, the Kato-Katz method, which was here used for the first time to detect this infection, has a higher diagnostic sensitivity and the advantage that a quantitative analysis of the eggs released in the host feces is possible.

Introduction: Glucose metabolism abnormality on type 2 diabetes mellitus (T2DM) caused liver damage due to dyslipidemia and increasing oxidative stress. Antidiabetic and antioxidants within green tea leaf and stevia leaf extract prevent liver damage due to T2DM complications. Objective: To investigate green tea and stevia leaf extract effects on liver histopathology on T2DM rats. Methods: This study used Post Test Only Control Group Design. A total of 30 Wistar rats were divided into 5 groups: control group (C-G), normal rats; negative control group (NC-G), T2DM induction; positive control group (PC-G), treated by Metformin; the first treatment group (T1-G), was treated by green tea leaf extract and stevia leaf extract; and the second treatment group (T2-G) was treated by a Metformin also green tea and stevia leaf extract. The treatment was given to subjects for 21 days starting 3 days after the induction of Nicotinamide (NA) and Streptozotocine (STZ). Histopathological assessment of liver cells uses assessment parameters in the form of features of necrosis, vacuolization, sinusoidal dilation and number of inflammatory cells. Hypothesis will be tested by Kruskal-Wallis (p<0,05) dan Mann-Whitney test (P<0,05) Results: The difference of liver damage in all group shows a significant difference, p<0.05. Significant differences in liver damage scores between the 2 groups there are between the negative control group and the control group (0.031), positive control (0.042), and second treatment group (0.011), and between first treatment group and second treatment group (0.041). Conclusion: The administration of green tea extract, stevia leaf, and standard drug may reduce liver damage score of Wistar with T2DM

Background and Aim:African swine fever (ASF) is currently the most prevalent disease in swine. The disease is spreading throughout primary swine-producing countries with heavy losses in population and revenue. To date, no successful vaccines or medications have been reported. This study aimed to design and develop a blend of natural essential oils and test its efficacy against the ASF virus (ASFV) in swine.Materials and Methods:We attempted to develop a natural oil blend formulation (NOBF) and determine its efficacy against the ASFV. This study follows on from a previously published in vitro study that reported that the NOBF has anti-ASFV properties. A study was designed using 21 healthy piglets of triple-cross (Landrace + Yorkshire + Durok) crossbred pathogen-free pigs with an average weight of 15 kg. The study consisted of NOBF-incubated, NOBF, positive control, and negative control groups. The NOBF groups were administered NOBF (80 mL/ton mixed in drinking water) beginning 10 days before the challenge and continuing throughout the experiment. The positive and negative control pigs consumed regular drinking water. The pigs were challenged by a sublethal dose of pure isolate ASFV strain Vietnam National University of Agriculture-ASFV-L01/HN/04/19 inoculation with 103.5 HAD50/dose through the intramuscular route. There were sic pigs in each group, three pigs directly IM challenged, and three pigs were considered cohoused pigs.Results:Both challenged (three) and cohoused (three) pigs in the positive control showed clinical signs of ASFV infection, as detected by real-time polymerase chain reaction (RT-PCR) in blood samples, oral swabs, and feces. There was 100% cumulative mortality, that is, both challenged and contact pigs died in the positive control group on day 20 of infection. No signs of infection or mortality were observed in the NOBF-incubated group. The challenged pigs in the NOBF-direct challenge group showed clinical signs and mortality, whereas no clinical signs or symptoms occurred in the cohoused pigs. The immunoglobulin G (IgG) level of the contact pigs was the highest in the treatment group and the lowest in the positive control group. The IgM level of the contact pigs in the treatment groups was the lowest, whereas that of the positive control was the highest. The RT-PCR test showed that the ASFV was deactivated in the NOBF-incubated group. The challenged and contact pigs of the positive control group had high Ct values. The challenged pigs of the NOBF group had high Ct values, whereas the contact pigs from the same group and those of the negative control were negative for the ASFV, determined by PCR, in all samples. The comparison of the challenged groups showed that the appearance of the virus was delayed by at least 2 days in the NOBF group compared to the positive control group.Conclusion:The results showed that NOBF can prevent the spread of the ASFV in a population. Moreover, NOBF can enhance the pig humoral immune system by enhancing IgG levels and reducing IgM levels. This study successfully demonstrated that NOBF is an anti-ASFV agent, which prevents horizontal transmission and enhances pig humoral immunity.

This study aims to investigate the impacts on the proliferation, inhibition, apoptosis, and cell cycle of hepatic stellate cells (HSC-T6) in rats by using traditional Chinese medicine (TCM) in serum. Twenty-seven rats were randomly divided into nine groups on average: a blank control (BC) group (fed by distilled water), a positive control group (colchicine solution, 0.05 mg/mL), and seven TCM groups [with the aim of clearing the liver of choleresis with 0.24 g/mL (weight of TCM herbs per milliliter), 0.73 g/mL, 1.22 g/mL, 2.45 g/mL, 7.34 g/mL, 12.24 g/mL, 24.48 g/mL]. Each rat received gavage with a dose of 1 mL/100 g twice a day for 7 days to prepare the drug serum. The HSC-T6 were divided into a TCM serum group, a positive control group, and a BC group. The TCM group and the positive control group were given corresponding drug serum for incubation, while the BC group received the medium without drug serum. The cellular proliferation inhibition rate in the positive control and TCM groups was significantly higher (P<0.01) than that in the BC group. The number of cells in the positive, 0.24 g/mL TCM, 1.22 g/mL TCM, and 7.34 g/mL TCM groups increased significantly (P<0.05) in the G0/G1 phase compared with the BC group. The number of cells in the positive group and all the TCM groups clearly increased in phase S by 0.73 g/mL in the TCM group, 2.45 g/mL in the TCM group, 12.24 g/mL in the TCM group, and 24.48 g/mL in the TCM group compared with the BC group, and the difference was statistically significant (P<0.05). The number of cells in the G2/M phase of the positive control group and all the TCM groups decreased significantly. Compared with the BC group, the positive group, 0.24 g/mL TCM group, 0.73 g/mL TCM group, 1.22 g/mL TCM group, 2.45 g/mL TCM group have statistically difference (P<0.05). A Qinggan Lidan prescription may exert anti-hepatic fibrosis effects by blocking HSC-T6 in the G0/G1 and S phases and by suppressing the proliferation of HSC-T6.
