Euphorbia milii and propolis combination tea reduced hepatic steatosis and hepatocyte apoptosis in high-fat diet rat model

Background: Dyslipidemia can cause various organ disorders, such as fatty liver disease. Over time, fatty liver disease has become more commonplace worldwide and may cause mortality if the progression worsens. Natural components from Euphorbia milii (E. milii) and propolis (EMP) have been demonstrated as immunomodulators that reduce total cholesterol levels.Objective: To prove the effect of EMP tea on inhibiting fatty liver and hepatocyte apoptosis in high-fat diet (HFD)-induced rats.Methods: This study applied a post-test-only control group design using 18 Wistar rats, which were divided into three groups: K0 (received standard feed), KN (received HFD of 2 g/200 g Body weight (BW) in a day), and P (received HFD of 2 g/200 g BW in a day and EMP of tea 40 mg/100 g BW in a day). The interventions were conducted for 30 days, followed by termination on day 31 for liver tissue collection and analysis. We calculated the hepatic steatosis with the help of hematoxylin-eosin (HE) staining. Hepatocyte apoptosis was also determined with terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) staining.Results: The K0 group had a lower hepatic steatosis percentage (17.87 ± 1.81) than KN (63.75 ± 15.88). We also found no hepatocyte apoptosis in the K0 but a high hepatocyte apoptosis index in the KN (3.98 ± 0.29). The combination of EMP tea in HFD-induced rats significantly reduced hepatic steatosis and apoptosis percentage (25.33 ± 1.17 and 0.91 ± 0.61, respectively). Conclusion: We demonstrated that combining EMP tea reduced hepatic steatosis and hepatocyte apoptotic index in HFD-induced rats, suggesting its potential as a treatment for these conditions.

THE EFFECT OF LEMON SKIN EXTRACT ON URIC ACID LEVELS OF HYPERURICEMIA MALE WISTAR RATS

Background: Uric acid is a metabolic process produced by each individual through the breakdown of purines carried out in the liver. Increased level of uric acid in blood is called hyperuricemia, which might cause gout if it is not treated properly. Lemon (Citrus Limon.) contains flavonoids which act as antioxidants and have the potential as antihyperuricemia Aim: This paper aimed to study the effect of lemon seed extract on uric acid levels Methods: Thirty-six male wistar rats from Farmhouse Ungaran were randomly divided into 6 groups, consists of healthy control group, hyperuricemic control, Allopurinol control, and treatment groups (3 groups). Hyperuricemia was induced by the administration of block broth and potassium oxonate for 4 weeks. Lemon seed extract doses of 17,5, 35, and 70 mg/kg BW, and Allopurinol 90 mg/kg BW was given orally for 2 weeks. Statistical analysis was conducted to evaluate differences among groups before and after the intervention. Results: There was a significant difference (p<0,05) in uric acid levels before and after intervention of lemon peel extract in groups K1, K2, and P3. Meanwhile, in groups K0, P1, and P2, there were no significant differences. In the pre-test uric acid levels, there was a significant difference (p<0,05) between the K0 group and K1, K2, P1, P2, and P3. Conclusion: There were no significant differences in the uric level acid of the treatment and control group after intervention, but there were significant differences in the effects of graded doses between the treatment groups.

Soursop leaves (Annona muricata Linn) ethanol extract prevents cisplatin-induced kidney injury of mice (Mus musculus) through SOD and MDA analysis

Background: Cancer treatment has been carried out in various ways, including surgery, chemotherapy and immunotherapy. Cisplatin is often used for chemotherapy, but the use of cisplatin still has extensive side effects, including kidney injury. The ethanol extract of soursop leaves contains antioxidants expected to reduce ROS or induce SOD, glutathione and catalase, thereby preventing kidney injury. This study aims to explain the effect of soursop leaves ethanol extract on preventing kidney injury caused by cisplatin administration in animal models. Method: This study is a true experimental study with a randomized, posttest-only control group design. We used 40 mice and randomly divided them into 5 groups, each group containing 8 mice. The K0 group was given aquadest, the K1 group was given cisplatin 20 mg/kgBW, the KP1 group was given cisplatin and soursop leave ethanol extract 100 mg/kgBW, the KP2 group was given cisplatin and soursop leave ethanol extract 200 mg/kgBW, the KP3 group given cisplatin and soursop leaves ethanol extract 400mg/kgBW. The extract was given orally for 5 days in a row. MDA and F2-isoprostane were measured using Immunohistochemistry. The data were all analyzed using an ANOVA test. Results: Soursop leaves ethanol extract with 200 mg/kgBW is the most effective dose to prevent kidney injury from cisplatin exposure. Soursop leaves ethanol extract can increase the expression of SOD and decrease the MDA metabolites. Conclusion: Soursop leaves ethanol extract can prevent kidney injury by increasing SOD and decreasing MDA.

NEPHROPROTECTIVE OF ETHANOL EXTRACT OF Annona muricata L. BARK ON PARACETAMOL-INDUCED NEPHROTOXICITY IN RATS

Kidneys are organs that have the potential for damage caused by toxic substances. The use of paracetamol in high doses or long-term therapeutic doses can cause adverse effects in the form of damage to the kidneys. Plants that have the potential to become medicinal raw materials against kidney damage are Annona muricata L. The purpose of this study was to determine the potential protection of ethanolic extract of soursop bark (EESB) against histopathological rat kidney induced by toxic doses of paracetamol. This study used an experimental method using a completely randomized design (CRD). The normal control group (K0) and negative control (K-) were given distilled water, while in the treatment group the doses of EESB were 150, 300 and 600 mg/kgBW dissolved in 1 ml of distilled water for 14 days. On the 7th day, all groups of rats were given paracetamol at a dose of 1350 mg/kgBW except for the K0 group. Each group was 5 repetitions, so that in this study used 25 rats (Rattus norvegicus L.). Samples of kidney organs were taken on the 14th day to observe the histopathological structure of the tubular cells undergoing necrosis. The results showed that at a dose of 300 mg/kgBW EESB had the potential for protection against kidney histopathology by suppressing the occurrence of cell death (necrosis).Keywords: Soursop bark, kidney, paracetamol, necrosis

Effect of Virgin Coconut Oil Administration to Increase HDL, Decrease LDL and IL-6 in Hypercholesterol Male Wistar Rats

Background: Hypercholesterol is a change in blood lipid profile levels, from rising cholesterol levels that can be triggered by frequent consumption of fatty foods. Hypercholesterol causes adipose tissue and macrophages to release inflammatory cytokines, then adipose cells release IL-6 and spur the formation of CRP. This study aimed to determine the effect of Virgin coconut oil (VCO) on changes in HDL, LDL, and IL-6 levels in hyper cholesterol mice. Subjects and Method: This randomized controlled trial was carried out at the PSPG UGM Nutrition Laboratory in August 2021. The total number of samples used was 20 tails and 4 spare tails, namely 24 male Wistar strain rats. Sampling using simple random sampling. The independent variables in this study were the dose of VCO 0.9 ml/200g BW/day, and 0.45 ml/200g BW/day. The dependent variables in this study were HDL, LDL, and IL-6 cholesterol levels in male Wistar rats. The data in the analysis used a normality test with the Shapiro-Wilk test and a data homogeneity test with the Levane test. HDL dan LDL levels were measured using a lysis reagent, while IL-6 was measured using the ELISA method. Results: Average LDL and HDL levels are highest in the P1 group compared to the P2, K0, and K1 groups. The One Way Anova test on HDL levels showed a significant difference between groups with p<0.001. One Way Anova test results on LDL and IL-6 levels showed significant differences between the groups (p<0.001) and (p= 0.004). Conclusion: Administering VCO at a dose of 0.9 mL/ 200 g BB/day 0.45 mL/200 g BB/day, and 86.4 mg/200 g can increase HDL and IL-6 levels in male rats Wistar strain with hyper cholesterol and lowered LDL levels by the same dose in male mice with hyper cholesterol.

A Hyperparameter-Free, Fast and Efficient Framework to Detect Clusters From Limited Samples Based on Ultra High-Dimensional Features.

Clustering is a challenging problem in machine learning in which one attempts to group N objects into K0 groups based on P features measured on each object. In this article, we examine the case where N ≪ P and K0 is not known. Clustering in such high dimensional, small sample size settings has numerous applications in biology, medicine, the social sciences, clinical trials, and other scientific and experimental fields. Whereas most existing clustering algorithms either require the number of clusters to be known a priori or are sensitive to the choice of tuning parameters, our method does not require the prior specification of K0 or any tuning parameters. This represents an important advantage for our method because training data are not available in the applications we consider (i.e., in unsupervised learning problems). Without training data, estimating K0 and other hyperparameters-and thus applying alternative clustering algorithms-can be difficult and lead to inaccurate results. Our method is based on a simple transformation of the Gram matrix and application of the strong law of large numbers to the transformed matrix. If the correlation between features decays as the number of features grows, we show that the transformed feature vectors concentrate tightly around their respective cluster expectations in a low-dimensional space. This result simplifies the detection and visualization of the unknown cluster configuration. We illustrate the algorithm by applying it to 32 benchmarked microarray datasets, each containing thousands of genomic features measured on a relatively small number of tissue samples. Compared to 21 other commonly used clustering methods, we find that the proposed algorithm is faster and twice as accurate in determining the "best" cluster configuration.

The effect of Eucalyptol on SOD and IL-10 expression in mice exposed to Methyl methacrylate vapor

Methyl methacrylate (MMA) is still widely used in medical, dental and industry. Inhalation is the important MMA occupational exposure route. Previous studies have shown that MMA may cause a wide range of adverse health effects such as hypersensitivity pneumonitis and increase the risk of asthma, nasal symptoms and phlegm. Eucalyptol, an active ingredient containing antioxidants has been shown to be able to inhibit the production of ROS and increase IL-10 anti-inflammatory cytokines. This study was done to determine the effect of eucalyptol on superoxide dismutase (SOD) and interleukin (IL)-10 expression in the airways of mice exposed to methyl methacrylate (MMA). This true experimental laboratory study involved the use of 30 mice as research subjects which were divided into five groups: a normal control group (K0), a positive control group (K1) and three treatment groups that were administered with 5mg, 10mg and 15mg doses of eucalyptol (P1, P2 and P3). The subjects were placed in a glass cage containing 150ppm MMA vapor nebulized with eucalyptol vapor for 120 minutes. The subjects were subsequently terminated and their lung tissue removed. Observation of the expression of SOD and IL-10 was carried out by immunohistochemical examination. MMA exposure significantly increased SOD (p <0.05). Administration of eucalyptol 5mg, 10mg and 15mg can reduce SOD, so that it was not different from K0 group. Only at a dose of 10mg and 15mg, eucalyptol was able to increase the expression of IL-10. It is concluded that Eucalyptol can reduce the expression of SOD and increase IL-10 expression in airway of mice exposed to MMA vapor.

Influence of Organic Selenium Application in Concentrate Mixtures on Selenium Content in Blood Plasma and Duck Feces

The aim of this study was to investigate the effect of the addition of different amounts of organic selenium (ALKOSEL® R397) in concentrate mixtures on the selenium content in the blood plasma and feces of ducks. The experiment was performed on 240 one-day-old ducklings (Cherry Valley) which were freely selected into 4 groups, one control K0 group, and three experimental K1, K2 and K3 groups. In two phases of feeding in fattening, ducklings were fed with two and nutritionally different concentrate feed mixtures: starter (from 1 to 14 days) and finisher (from 15 to 49 days of fattening). The control group of ducklings (K0) during feeding received food without added organic selenium in both phases of fattening. In both phases of fattening, the experimental group of ducks K1 was fed with food as well as the control group, but with the addition of 0.2 mg/kg of organic selenium, while the experimental group K2 used food with 0.4 mg/kg, and the experimental group K3 with 0.6 mg/kg of organic selenium. The addition of organic selenium to duck feed had the effect of increasing selenium content in both blood plasma and duck feces. The highest content of selenium in blood plasma and feces was determined in the group of ducks that received the highest amount of organic selenium through food during the entire experiment.

Effect of low-dose ketamine on MACBAR of sevoflurane in laparoscopic cholecystectomy: A randomized controlled trial.

Low-dose ketamine can reduce the minimum alveolar concentration of sevoflurane necessary to block the adrenergic response (MACBAR ) in animals. However, the effects of low-dose ketamine on the sevoflurane MACBAR in patients undergoing laparoscopic surgery are unclear. The aim of this study was to investigate the effects of three different low doses of ketamine on the MACBAR of sevoflurane in patients undergoing laparoscopic cholecystectomy. One hundred patients who underwent laparoscopic cholecystectomy were enrolled. After general anaesthesia induction and tracheal intubation, patients received sevoflurane anaesthesia in combination with a loading dose of saline followed by infusion or a loading dose of 0.5mg/kg ketamine followed by a continuous infusion of 5 (K1 group), 10 (K2 group) and 20μg/kg/min (K3 group). The target concentration of end-tidal sevoflurane was maintained for at least 20minutes before carbon dioxide pneumoperitoneum stimulus. The MACBAR of sevoflurane in each group was determined by using an up-and-down sequential allocation technique. Seventy-one patients completed the study. The values of MACBAR for sevoflurane were 5.3% in the K0 , 4.8% in K1 , 3.3% in K2 and 3.2% in K3 groups. The use of ketamine significantly reduced the MACBAR of sevoflurane compared to sevoflurane alone. The K2 and K3 groups showed significantly lower values of MACBAR than that in the K1 group. However, a higher dose of ketamine in the K3 group did not further reduce the sevoflurane MACBAR . The mean arterial blood pressure (MAP) values before pneumoperitoneum in the K2 and the K3 groups were significantly higher compared to those in the K0 and K1 groups. Compared with the values before pneumoperitoneum, the heart rate and MAP after pneumoperitoneum were significantly increased. Overall, the haemodynamics remained stable during the study period in all groups. A loading dose of 0.5mg/kg ketamine followed by a continuous infusion of 10.0μg/kg/min led to a significant decrease in the MACBAR of sevoflurane in patients undergoing laparoscopic cholecystectomy.

CYTOTOXICITY ASSAY USING BRINE SHRIMP LETHALITY TEST ON COLLAGEN-CHITOSAN WOND DRESSING STERILIZED BY ULTRAVIOLET LIGHT

Collagen gives a moist state on the wound area to accelerate the wound healing process. Chitosan is a polymer as known as non-toxic, antibacterial, antifungal, biodegradable, and biocompatible materials. Combination of collagen and chitosan expected to be the best biomaterials as a wound dressing for the healing process. The study aimed to determine cytotoxicity assay on collagen-chitosan wound dressing sterilized by ultraviolet (UV) Light using Brine Shrimp Lethality Test (BSLT) method. The test groups were divided into K0, K1, K2, and K3 groups. K0 contained pure chitosan as a control group, K1 contained collagen 25%-chitosan 75%, K2 contained collagen 50%-chitosan 50%, K3 contained collagen 75%-Chitosan 25%. Collagen extracted from skin and scalp of snakehead fish (Channa striata) then mixed with chitosan until formed collagen-chitosan wound dressing. This study used Brine Shrimp Level Test (BSLT) method with solution concentration 10, 50, 100, 250, 500, 750 and 1000 ppm. Based on the results showed that K0, K1, K2, and K3 group had LC50 > 1000 that proven collagen-chitosan wound dressing was non-toxic materials. As conclusion of the study explained composite wound dressing based on collagen-chitosan in all groups that sterilized under UV-Light along 15 minutes was not toxic based on Brine Shrimp Lethality Test showed LC50> 1000.

This research aimed to determine the effect of giving Sipatah-patah extract toward the histopathological and femur bone growth of white rat that was ovariectomized. The experimental animals that were used were 12 white rats divided into 4 treatment group with 3 repetitions. K0 was the ovariectomized rat without giving Sipatah-patah extract (ESP); K1, K2 and K3 were ovariectomized rats which were given Sipatah-patah extract with multilevel doses of 500 mg/kg BW, 700 mg/kg BW and 900 mg/kg BW for 30 days. On the 31st day, rats were euthanized using chloroform and os femur that was taken to being made into histological preparation. There was the decrease in the bones density of the K0 group which is characterized by thinning of trabecular structure, there were lots of osteoclast cells on the edge of the trabecular and lower density of active osteoblasts and passive osteoblasts. The rat of group K1 and K2 showed an improvement on the trabecular structure and lower osteoclast than group K0. The rat of group K3 had a visible improvement of the most congested trabecular structures, cohesive with the most density cell of active osteoblasts than the other groups. The result of this research concluded that the giving of Sipatah-patah extract doses 900 mg/kg BW showed a higher density of trabecular and active osteoblasts than the control group, K1 and K2 on the white rat bones that were ovariectomized.

At the end of treatment (day 14th), testes, epididymis (caput, corpus, and cauda) and ductus deferens samples were taken through the close-castration method for examining the testosterone and DHT concentration by using enzyme-linked immunosorbent assay (ELISA) technique. Data gathered were later analyzed using ANOVA followed by Tukey’s HSD in SPSS 16.0 for Windows. The result showed that the average concentration of testosterone on K0, KP1, KP2, KP3, and KP 4 in testis respectively were 10.00±2.64 ng/ml; 7.66±2.51 ng/ml; 10.00±6.55 ng/ml; 0.66±0.57 ng/ml; 11.66±7.37 ng/ml; caput epididymis; 5.00±1.73 ng/ml; 2.33±1.52 ng/ml; 5.00±2.64 ng/ml; 1.33±0.57 ng/ml; 5.66±1.15 ng/ml; corpus epididymis; 1.33±0.57 ng/ml; 0.66±0.57 ng/ml; 4.00±2.64 ng/ml; 0.66±0.57 ng/ml; 4.33±2.30 ng/ml; cauda epididymis: 1.00±0.00 ng/ml; 0.66±0.57 ng/ml; 1.66±0.57 ng/ml; 1.00 ± 0.00 ng/ml; 2.00±1.73 ng/ml; ductus deferens: 3.66±2.51 ng/ml; 0.66±0.57 ng/ml; 3.00±1.00 ng/ml; 1.00±0.00 ng/ml and 3.66±1.15 ng/ml. While the average concentration of DHT on K0, KP1, KP2, KP3, and KP 4 in testis respectively; 10.00±2.64 ng/ml; 7.66±2.51 ng/ml; 10.00±6.55 ng/ml; 0.66±0.57 ng/ml; 11.66±7.37 ng/ml; caput epididymis; 5.00±1.73 ng/ml; 2.33±1.52 ng/ml; 5.00±2.64 ng/ml; 1.33±0.57 ng/ml; 5.66±1.15 ng/ml; corpus epididymis; 1.33±0.57 ng/ml; 0.66±0.57 ng/ml; 4.00±2.64 ng/ml; 0.66±0.57 ng/ml; 4.33±2.30 ng/ml; cauda epididymis: 1.00±0.00 ng/ml; 0.66±0.57 ng/ml; 1.66±0.57 ng/ml; 1.00 ± 0.00 ng/ml; 2.00±1.73 ng/ml; ductus deferens: 3.66±2.51 ng/ml; 0.66±0.57 ng/ml; 3.00±1.00 ng/ml; 1.00±0.00 ng/ml and 3.66±1.15 ng/ml. Statistical analysis showed that the administration of EE only increased testosterone concentration in testes had significant effect (P 0.05). From this study, it can be concluded that the EE has the potential to improve spermatogenesis and sperm quality through increasing the testosterone concentration in the local male goats.

Melatonin menurunkan berat badan tetapi tidak menurunkan kadar TNF-α pada tikus wistar jantan yang diberi minyak jelantah selama 28 hari

Backgound: Non Alcoholic Fatty Liver Disease (NAFLD) occurs when the intake and free fatty acid synthesis occurs more frequently than its oxidation and resecretion in the blood. Melatonin is a powerful antioxidant that can boost the synthesis of endogenous antioxidants in the body, suppress the inflammatory response and inhibit the formation of steatosis.Objective: To analyze the effect of melatonin supplementation in reducing body weight andTNF-α levels in male Wistar rats were fed by waste cooking oil.Methods: True experimental studyusing post-test only control group design. This study was done on 18 male wistar rats were divided into 3 groups : the positive control group (P0) was administrated waste cooking oil, the treated group 1 (P1) was administrated waste cooking oil and 5mg/kgBW melatonin, and the treated group 2 (P2) was administrated waste cooking oil and 10mg/kgBW melatonin for 28 days.Data analysis using One Way ANOVA test and followed by Tukey test to determine the most effective dose of melatonin.Results: There was significant difference in body weightbetween P2group and K0 group (p=0,019) with the mean body weight difference was 19,167g lower than K0 group. There was no difference in TNF-α levels between the three groups (p=0,155). Conclusion: Melatonin dose of 10mg/kgBWloses body weight male Wistar rats have given by waste cooking oil for 28 days, but does not reduce TNF-α levels.

The expression of cyclic adenosine monophosphate responsive element modulator in rat sertoli cells following seminal extract administration.

Aim:This study aims to determine the effect of seminal vesicle extract on cyclic adenosine monophosphate responsive element modulator (CREM) expression in rat Sertoli cells.Materials and Methods:This study examined the expression of CREM on 20 male rats (Rattus norvegicus) at 4 months of age, weighing 250-300 g. The rats were divided into four groups: K0, KP1, KP2, and KP3. K0 group was injected with 0.2 ml normal saline; KP1 was injected with 25 mg cloprostenol (Prostavet C, Virbac S. A); KP2 and KP3 were injected with 0.2 and 0.4 ml seminal vesicle extract, respectively. The treatments were conducted 5 times within 12-day interval. At the end of the study, the rats were euthanized by cervical dislocation; then, the testicles were necropsied and processed for histology observation using immunohistochemistry staining.Results:CREM expression in rat Sertoli cells was not altered by the administration of either 0.2 or 0.4 ml seminal vesicle extract.Conclusion:The administration of seminal vesicle extract is unable to increase CREM expression in rat Sertoli cells.
