ABSTRACTBackground: Stimulation of inflammatory cells such as polymorphonuclear cells (PMN) will initiate to release free radicals in destroying bacteria. Excessive free radicals can damage cells in the body. Antioxidants as one of the body's defense systems will neutralize existing free radicals. Chitosan from Haruan scales in addition to being antimicrobial turned out to also be antioxidants. Objective: To know the antioxidant potential of chitosan from haruan (Channa striata) scales. Methods: This study is a pure experimental (true experimental design) with a post-test only with control group design using two treatment groups, with quantitative tests to calculate the amount of antioxidant activity of chitosan from fish scales using DPPH radical reduction method. The first treatment is 4, 6, 8 and 10 ppm standard ascorbic acid concentration with DPPH solution as positive control, and the second treatment is 200, 250, 300 and 350 ppm chitosan from Haruan scales concentration with DPPH solution. Results: The results showed that chitosan from Haruan fish scales have antioxidant activity with 50.513% percentage of inhibition at a maximum concentration of 350 ppm with an IC50 value of 356.98 ppm. The results of the independent T-test showed that there was a significant difference between the inhibition percentage of chitosan from haruan fish scales and the inhibition percentage of ascorbic acid (p = 0,000) (p <0.05). Conclusion: Chitosan from Haruan fish scales proved to have antioxidant activity.Keywords: Antioxidants, Chitosan, Haruan fish scalesABSTRACTBackground: Stimulation of inflammatory cells such as polymorphonuclear cells (PMN) will initiate to release free radicals in destroying bacteria.

This study aimed to investigate the key constituents and preliminary mechanism for the hypolipidemic activity of chrysanthemum flavonoids. Hyperlipidemia (HPL) rats were divided into five groups: the model control group (MC); Chrysanthemum flavone intervention group (CF); luteolin intervention group; luteoloside intervention group and simvastatin intervention group. The body weight, organ coefficient, serum lipids, antioxidant activity, and lipid metabolism enzymes were detected. Hematoxylin and eosin (H&E) staining was used to observe the liver and adipose tissue. Chrysanthemum flavonoids, luteolin, and luteoloside can reduce the weight and levels of total cholesterol (TC), triglycerides (TG), and LDL-C, and increase the level of HDL-C in the blood and reduce liver steatosis. Indicators of liver function (AST, ALT, and ALP) improved. The antioxidant activity (GSH-Px, CAT, SOD) and enzymes associated with lipid catabolism (FAβO, CYP7A1, and HL) increased, while lipid peroxidation products (MDA) and enzymes associated with lipid synthesis (FAS, HMG-CoA, and DGAT) decreased. Chrysanthemum flavonoids had a better effect on the antioxidant level and lipid metabolism-related enzyme activity. There was no significant difference in the effects of the chrysanthemum flavonoids, luteolin, and Luteoloside on improving blood lipids and hepatic steatosis—mechanisms that may be related to antioxidant levels and regulating enzymes involved in the metabolism of fatty acids, cholesterol, and triglycerides in the liver. However, chrysanthemum flavonoids had a stronger antioxidant and lipid metabolism regulation ability, and the long-term effects may be better.

Introduction: Kembang Bulan (Tithonia diversifolia) is one of Indonesian traditional medicine that contains saponins, flavonoids, and, tannins and is predicted has a lowering effect on blood-glucose. Diabetes mellitus (DM) is a disease caused by insufficient insulin secretory by the pancreas or ineffective usage of insulin that produced by the body thus cause a hyperglycemia condition. Hyperglycemia can cause an increase in Reactive Oxygen Species which can cause free radicals. Free radicals can cause damage to liver cells. Method: This was an experiment with posttest control group design. Samples were 40 rats, divided into five different groups (P1, P2, P3, P4 and P5). Each group were induced by multiple low doses STZ. P1 (give the extract of Tithonia diversifolia at a dose 50 mg/100 gr BB), P2 (give the extract of Tithonia diversifolia at a dose 150 mg/100 gr BB), and P3 (give the extract of Tithonia diversifolia at a dose 450 mg/100 gr BB), P4 was treated with metformin, P5 was not treated. After STZ induction and give the extract to diabetic rat model, the resulting liver cell damage will be measured using the SGOT and SGPT measurement methods. Result: On the average results of SGOT levels in the five treatments, using the ANOVA test p value was 0.877 (p> 0.05) which means there were no significant differences. Furthermore, on the average results of SGPT levels in all five treatments, using the ANOVA test p value was 0.822 (p> 0.05) which means there were no significant differences. But from all results obtained P4 (given metformin) with the results closest to normal levels (SGOT: 197.5 ± 37.25; SGPT: 90.33 ± 29.36). From the treatment given Tithonia diversifolia extract obtained P1 (with a dose of 50 mg / 200gr BB) with the results closest to normal levels compared to P2 and P3. Conclusion: The Extract of kembang Bulan Leaf (Tithonia diversifolia) obtained less significant results compared to the untreated group. However, there is no significant difference. And giving ethanol extract of the leaves of kembang Bulan (Tithonia diversifolia)  at a dose of 50 mg / 100gr BB is the most effective way to reduce levels of SGOT and SGPT.

The popularity of E-Cigarette has increased significantly over the last decade, and has potential to replace tobacco cigarettes. Aerosol which is produced by E-Cigarette, contains reactive carbonyl and free radicals, inducing oxidative stress and causing inflammation, proliferation, and cell damage. This oxidative stress can be seen through the Malondialdehyde (MDA) levels in the body, and reduced by antioxidant activity in Solo Garlic extract. The aim of this study is analyzing the differences of MDA levels in four treatment groups. 28 white rats were divided into four groups and three of them were exposured by E-Cigarette. This study showed that the highest MDA levels was found in the group which was exposured by E-Cigarette without solo garlic extract (7,179 nmol/ml). MDA levels can be reduced by antioxidant activity shown in the group which was exposured by E-Cigarette and solo garlic extract dose 0,05 gram/day (the smallest dose), amount 3,715 nmol/ml. The average of MDA levels in group which was given by the smallest dose of solo garlic extract, is lower than the control group. So, it can be concluded that using solo garlic extract less than 0,05 gram/day can restore MDA levels to a normal state (4,210 nmol/ml).

Medical students are constantly getting stress that could lead to oxidative stress where the level of free radicals is higher than the level of antioxidants in the body. Free radicals can bind to erythrocyte membranes and alter membrane structure that lead to the integrity of the erythrocyte membrane resulting in decreased erythrocyte ability in preventing hemolysis. Vitamin C is an antioxidant that could prevent free radicals bond to erythrocyte membrane. Vitamin C works by donating electrons to free radicals and prevent binding to erythrocyte membranes. The purposed of this study was to determine the effect of vitamin C consumption on osmotic fragility of erythrocytes in medical students with psychological stress. This research was clinical trial research with quasi experimental with pretest-posttest control group design. Researchers used Depression Anxiety Stress Scale (DASS) questionnaire to measure the stress level. Data analysis using T test obtained mean of percentage of hemolysis between pretest and posttest was   p= 0,02. It can be concluded that there is significant difference on osmotic fragility due to Vitamin C consumption in medical Student of Jember University with psychological stress.

Previously, we have found that the addition of L-ascorbic acid to chitosan enhanced the reduction in body weight gain in guinea pigs fed a high-fat diet. We hypothesized that the addition of L-ascorbic acid to chitosan would accelerate the reduction of body weight in humans, similar to the animal model. Overweight subjects administered chitosan with or without L-ascorbic acid for 8 weeks, were assigned to three groups: Control group (N = 26, placebo, vehicle only), Chito group (N = 27, 3 g/day chitosan), and Chito-vita group (N = 27, 3 g/day chitosan plus 2 g/day L-ascorbic acid). The body weights and body mass index (BMI) of the Chito and Chito-vita groups decreased significantly (p < 0.05) compared to the Control group. The BMI of the Chito-vita group decreased significantly compared to the Chito group (Chito: -1.0 kg/m2 vs. Chito-vita: -1.6 kg/m2, p < 0.05). The results showed that the chitosan enhanced reduction of body weight and BMI was accentuated by the addition of L-ascorbic acid. The fat mass, percentage body fat, body circumference, and skinfold thickness in the Chito and Chito-vita groups decreased more than the Control group; however, these parameters were not significantly different between the three groups. Chitosan combined with L-ascorbic acid may be useful for controlling body weight.

ABSTRACT Toilet training is an effort to train children to be able to control and urinate (BAK) and defecate (BAB). Toilet training is one of the main tasks of children at toddler age. Toilet training is one of the main tasks of children in toddler age which is very important to be done to create independence in children in controlling BAK and BAB and children know the parts of the body and their functions. Data in 2012 shows that ± 60% of parents do not teach toilet training to children from an early age. The aim of the study was to find out the effectiveness of toilet training education on maternal behavior and toilet skills in toddler age training (18-36 months). The study was conducted in July-August 2018. This type of quantitative research used the design of the Quasy pretest and posttest experiment with non-equivalent control group design. Samples were 36 mothers and 36 children with purposive sampling technique. Data analysis used Paired t test, Wilcoxon test, Man-Whitney test an Independent t test. The results showed that toilet training education through lecture methods, modules and maze games was more effective than toilet training education through lecture and leaflet methods on children's knowledge and abilities. Conversely, for the role of mothers in supervision there is no significant difference in effectiveness. Health education is recommended in health promotion programs to increase maternal knowledge, the role of mothers and the ability of toilet training children independently.

The Relationship

The predominance of synthetic and genetically modified foods in the diet of a modern person often leads to disruption of natural metabolic processes and the accumulation of toxic free radicals in the body, which provokes the development of various diseases. Natural antioxidants from medicinal plants can help maintain health and stop the processes of peroxidation. In our opinion, Аstragalus onobrychis can become a promising source of natural antioxidants. The aim of this study was to establish the antioxidant activity in extracts from the herb Astragalus onobrychis. In order to obtain objective and reliable results during our research, we used two methods: the method of titrimetry and spectrophotometry of free radicals. The titrimetric method is based on the chemical interaction between an oxidizing agent (potassium permanganate) and natural antioxidants present in extracts from plant raw materials, since they exhibit the properties of reducing agents. The spectrophotometric method makes it possible to assess the value of antioxidant activity and the duration of the reaction by assessing the interaction of 2,2-diphenyl-1-picrylhydrazil with plant antioxidants. To establish the relationship between the antioxidant activity and the presence of phenolic compounds in the plant, the content of flavonoids and hydroxycinnamic acids in the herb Astragalus onobrychis was determined. As a result of the studies, the total antioxidant activity of extracts from the herb Astragalus onobrychis was established and it was revealed that its value depends on the type of extractant used, since this factor is associated with the content of various groups of natural antioxidants in the extraction. The data obtained indicate the prospects of using the herb Astragalus onobrychis as a source of natural antioxidants.

Buprenorphine drug cartridge was made for autoinjector device for use in emergency and critical situations to reduce the morbidity and mortality. Water-filled cartridges were prepared and buprenorphine was injected aseptically in the cartridge, to make 0.05 and 0.10 mg/mL. Rats were injected intraperitoneally, buprenorphine (0.3 and 0.6 mg/kg), repeatedly with the autoinjector and compared with manual injection (7 days and 14 days) using various haematological and biochemical parameters. No significant change was observed in the body weight, organ to body weight ratio and haematological variables in any of the experimental groups compared with the control group. Except serum urea and aspartate aminotransferase, no significant change was observed in glucose, cholesterol, triglycerides, bilirubin, protein, albumin, creatinine, uric acid, alanine aminotransferase, gamma glutamyltransferase and alkaline phosphatase. The autoinjectors deliver the drugs with spray effect and force for faster absorption. In the present study, the autoinjector meant for intramuscular injection was injected intraperitoneally in rats, and the drug was delivered with force on the vital organs. No significant difference was observed in the autoinjector group compared to the manual group showing tolerability and safety of the buphrenorphine autoinjector. This study shows that buprenorphine autoinjector can be considered for further research work.

Childhood Adjustment

This report deals with the findings from a study of twenty-eight children, all of whom had ventricular septal defects and were studied by the same cardiovascular team. One-half of the group had a surgical procedure for correction of the defect. The study investigated three problems in children with ventricular septal defect ( VSD). (1) Do children with surgical intervention for VSD show greater impairment of intellectual functioning than non-operated children? (2) Do children with surgical intervention show greater emotional disturbance than non-operated children? (3) Do children with surgical intervention show greater alteration of body image than do non-operated children? Data were collected using questionnaires, family interviews, subject interviews, medical records, school reports, physicians' reports and Human Figure Drawings, both inside and outside the body. The findings conclude that ( a) operated children do demonstrate significantly more impairment of intellectual functioning; ( b) there was no significant difference in the incidence of emotional disturbances between the two groups but that these twenty-eight children with VSD were more similar emotionally to children in a psychiatric clinic group than in a control group; and ( c) the only indication of altered body image was found in the greater frequency with which bones were drawn by the operated group.
