Regulation of blood glucose levels and body fat is critical for survival. Leptin circulates freely in blood and controls body weight and food intake mainly through hypothalamic receptors and regulates glucose metabolism in the liver both directly through leptin receptors and indirectly via the hypothalamic receptors of central nervous system. Leptin affects food intake regulation and eventually glucose metabolism, lipometabolism, endocrine and immune functions, reproductive function, adipose tissue metabolism and energy expenditure...

Plants are used traditionally throughout the globe to treat various diseases. Traditionally used medicinal plants are an essential part of the health sector in Bangladesh due to its abundance of a vast source of ethno-medicine. Rural people from developing country like Bangladesh are greatly dependent on traditional source of medicine. The prevalence of diabetes mellitus is increasing from recent years; therefore various researches are going on to discover better medicine to treat this disease. This study has focused on five plants which are Andrographis paniculata, Ageratum conyzoides, Swertia chirata, Terminalia arjuna, and Azadirachta indica to find out their traditional formulation as anti-diabetic medicine and their pharmacological activity has also been explored through literature search...

In Indonesia, there are at least 1.3 million cases of malaria each year and Plasmodium falciparum appears to be the most common Plasmodium. The finding of Plasmodium is important for the diagnosis and management of malaria. This is a case of a 4-year-and-9-month-old male who lived in Manado, East Indonesia. He presented with a prolonged fever, was pale in appearance, and was easily fatigued over the last 3 weeks. Hepato-splenomegaly was found on the initial physical examination. Preliminary laboratory findings found pancytopenia and severe anemia...

OBJECTIVE: To investigate the diuretic, hypotensive and renal effect of Opuntia ficus-indica in two different species in oral and intravenous administration. METHODS: Diuretic activity was evaluated in rats with the plant cladode gel and aqueous extract administrated orally, and was evaluated in rabbits with plant extract administered intravenously. Single and repeated doses of cladode gel or aqueous extract of cladode were tested. Urine volume and blood and urine creatinine, sodium and potassium were measured, and creatinine clearance was calculated...
