The non-proliferative activity of isolated saponins, gymnemagenol (C30H50O4) from Gymnema sylvestre and dasyscyphin C (C28H40O8) from Eclipta prostrata leaves were tested under on HepG2 cells under in vitro conditions. Both gymnemagenol and dasyscyphin C exhibited non-proliferative activity on HepG2 cells at 24 h with the IC50 value of 18.5 and 23.5μg/ml respectively. 5-Fluorouracil (5FU) a positive control showed the IC50 value of 1.34μg/ml. The isolated saponins were not toxic to Vero cells. From this study, it can be concluded that the saponins, gymnemagenol and dasyscyphin C have significant non-proliferative activity on HeLa cells under in vitro...

The community pharmacist, being an important member of the healthcare team and society, can make successful efforts to counsel the sufferer and guide him about this disease. Pharmacist is now becoming more patient oriented than product oriented and have brought many changes in life of patients. Hypertension or high blood pressure is a condition in which the blood pressure in the arteries is chronically elevated. With every heart beat, the heart pumps blood through the arteries to the rest of the body. Blood pressure is the force of blood that is pushing up against the walls of the blood vessels. If the pressure is too high, the heart has to work harder to pump, and this could lead to organ damage and several illnesses such as heart attack, stroke, failure, aneurysm, or renal failure. Cardiovascular diseases caused 2.3 million deaths in India in the year 1990; this is projected to double by the year 2020. Hypertension is directly responsible for 57% of all stroke deaths and 24% of all...

Alzheimer’s disease (AD) is a leading cause of morbidity and mortality and its prevalence is continuously increasing. AD is characterized to varying degrees by Amyloid β, neurofibrillary tangles, gliosis, synaptic and neuronal loss leading to a decline in memory & apraxia agnosia and several neuropsychiatric changes like anxiety and depression etc. Increased age, oxidative stress and neuroinflammation are considered to be the major risk factors implicated in the progression of AD. Various signaling systems, such as vasoconstrictor peptides, inflammatory mediators, growth factors, are involved in the pathogenesis of AD. At present, no promising therapy is available due to lack of understanding of signaling culprits involved in the pathogenesis of AD. Animal models are being developed to better understand the disease pathogenesis and develop drugs for this ailment. In the present review, various common lab animal models for AD are discussed, which has been used, can be used and which will open new vistas for developing new drugs to treat this cognitive...

Filariasis is the name for a group of tropical diseases caused by various thread-like parasitic round worms (nematodes) and their larvae. The larvae transmit the disease to humans through a mosquito bite. Filariasis is characterized by fever, chills, headache, and skin lesions in the early stages and, if untreated, can progress to include gross enlargement of the limbs and genitalia in a condition called elephantiasis. While filariasis is rarely fatal, it is the second leading cause of permanent and long-term disability in the world. The World Health Organization (WHO) has named filariasis one of only six “potentially eradicable” infectious diseases and has embarked upon a 20-year campaign to eradicate the disease. These infections have a significant economic and psychosocial impact in endemic areas, disfiguring and/or incapacitating more than 40 million individuals. Studies from the Indian subcontinent have shown that infected patients lose significant time from work because of the disease costing the national treasury a minimum of $842 million per year. The treatment of filariasis consists of using medicines that kill the worms combined with...
