Abstract Leptin can reverse hyperglycemia in rodent models of type 1 diabetes. However, these models have used chemical or immune mediated β-cell destruction where insulin depletion is incomplete. Thus it is unknown which actions of leptin are entirely insulin independent, versus those which require insulin. To directly assess this we maximized blockage of insulin action using an insulin receptor antagonist in combination with streptozotocin-diabetic mice; leptin treatment was still able to reduce blood glucose. Next, we leptin-treated adult insulin knockout (InsKO) mice. Remarkably, leptin-treated InsKO mice were viable for up to 3 weeks without insulin therapy. Leptin treatment reduced plasma corticosterone, glucagon, β-hydroxybutyrate, triglycerides, cholesterol, fatty acids and glycerol. However, leptin-treated InsKO mice exhibited overt fed hyperglycemia and severe fasting hypoglycemia. Therefore, leptin can normalize many metabolic parameters in the complete absence of insulin, but blood glucose levels are volatile and the length of survival finite.

Background: Therapies for hyperglycemic treatment, including insulin and oral diabetes medications, have been confirmed to cause several side effects. Thus, finding new drugs with fewer side effects is of high importance. Salung leaf herb (Psychotria malayana Jack) reported used in traditional societies as a treatment for diabetes. However, the scientific proof of this plant for diabetes treatment is still lacking.Objective: To evaluate the antidiabetic effect of the P. malayana jack in induced type 1 diabetic rats by assessing blood glucose level and pancreatic cells in white rats.Methods: Alloxan used to induce type I diabetes. Rats randomly divided into six groups. A Group P1 received 250 mg/kg BW; group P2 received 500 mg/kg BW, group P3 received 1000 mg/kg BW. While group 4 basal received no treatment, group 5 received distilled water as a negative control, and group 6 received glibenclamide as a positive control. Medications are given for six days. Glucose levels were measured, and observation of pancreatic Langerhans cell damages.Results:  A decrease in blood glucose levels observed in all treatment groups. The most significant reduction (49.76%; 1000 mg/kg BW) occurred in the P3 group. Morphological features of pancreatic Langerhans cell damage were slightly high in the P1 group.Conclusion: P. malayana Jack can consider having an antidiabetic effect in a type 1 diabetic rat by reducing blood glucose levels.

Tithonia diversifolia is a plant that has the potential to reduce blood glucose levels that is crucial in Diabetes Mellitus therapy. This study aims to determine the active compounds contained in the extract of T. diversifolia leaves decoction, the effect of decoction extract on the reduction of blood glucose, and the most effective decoction extract to reduce blood glucose levels as well. The study used a Completely Randomized Design (CRD) with the research treatment groups, namely: Kn = normal control (normal mice and not given leaves decoction extract), Ka = STZ control (DM mice, which are normal mice induced by 65mg/Kg of STZ), Kp = treatment control (normal mice given leaf decoction extract) , P1 = DM + mice were given young leaf decoction extract, P2 = DM + mice were given a mixture of young leaf and adult leaf decoction extract, P3 = DM + mice were given adult leaf decoction extract. The leaves used for decoction were 1-6 leaves from the shoots. The analysis of T. diversifolia leaves decoction compounds is using the visible spectrophotometers for tannins, phenols and flavonoids and GC-MS for terpenoid analysis. The result found that Tithonia diversifolia leaves decoction extracts contain tannins, flavonoids and phenols, while terpenoids are not detected. The leaves decoction extracts of T. diversifolia influenced the decreases in blood glucose levels of DM mice, especially the decoction extract of adult leaves which reduced blood glucose levels to 71.16%.

Reduce Blood Glucose

Functional food is food that is naturally or through a process that is beneficial to health. One functional food is a green bean juice packaging beverage that can reduce blood glucose levels. High fiber content, low glycemic index and flavonoids, and polyphenols in green beans (Phaseolus radiatus L) can reduce glucose levels in the blood. This study used experimental animals 7 tails. All experimental animals were given packaged mung bean juice 2 times a day for 9 days by means of a round. The mean results of an examination of blood glucose levels in white rat experimental animals before giving packaged green bean juice drinks was 85 mg dl, while the average results of an examination of blood glucose levels in experimental rats after administration of packaged green bean juice were 75 mg/dl. The results of the Paired T-test statistical test obtained p = 0,000 <α = 0.05. Packaged green bean juice can reduce blood glucose levels in animals testing white rats.

The diagnosis of Type 1 Diabetes (T1D) will come as an unwelcome surprise to most people. Within a short period of time, the person will have to come to understand and manage this chronic illness. The terminology associated with the T1D condition will also be totally new to the person: diabetes mellitus, pancreas, hyperglycaemia (hyper), hypoglycaemia (hypo), bolus (fast acting insulin), basal (slow acting insulin), ketones and blood glucose levels. The purpose of this article is to assist newly diagnosed patients' understanding of T1D, people who are already living with T1D, carers of people with T1D, partners and family members of someone with T1D, work colleagues, and friends who participate in the same sporting activities or go on holiday with a person who has T1D. In addition, this article reviews how people living with T1D can still enjoy exercise and maintain the best quality of life possible; whilst controlling the blood glucose levels in their body for the rest of their lives to prevent the onset of complications associated with diabetes.
