Evaluation of pharmacological activity of chadraprabha vati on serum of albino wistar strain rats

The current study is to develop the acute and sub-acute toxicity profile of some ayurvedic Bhasma and un-derstand the side effects due to the presence of heavy metals. Chandraprabha vati pill were weighed, powdery and suspended in water had made into liquid formulation. The animals were classified and treated with the doses of Chandraprabha vati (50and five hundred mg/kg) in rat. The dose was calculat-ed by extrapolating the equivalent human dose (1 and ten times) and was administered orally between ten and eleven after median daily for twenty eight days, during alylin a very volume not exceeding one ml/100 g rat weight. Blood was collected on seven, fourteen and twenty eight days, later they were sacri-ficed for histopathological studies.

Cardioprotective effect of pulicaria wightania against isoproterenol induced myocardial infarction in experimental rats

The current study was carried out to evaluate the cardio protective activity of Pulicaria Wightiana against Isoproterenol (ISO) induced myocardial infarction (MI). Pretreatment to the different groups were given for 30 days and ISO was administered at last two days with an interval of 24 hrs. Due to chronic ionotropy ISO induces MI. Blood was collected at the last day of experimental period and biomarkers were observed. The results indicate that the extract exhibited significant cardioprotective activity.

Evaluation and phytochemical screening and antibacterial activity of Ficus dalhousiae Miq

The aim of the present study was to isolate the Extract from the leaves of Ficus dalhousiae Miq and subse-quently evaluate their antibacterial and antifungal activity. The crude various extracts of the plant n-Hexane, Chloroform, Ethyl acetate, Methanol extract was obtained by using continuous soxhlation tech-nique using soxhlet apparatus. The antibacterial activity of plant extract were carried using cup plate method against three bacterial species Staphylococcus aures, Bacillus subtilis, Escherichia coli using agar diffusion method. those are compared with standard reference drug Ciprofloxacin. This study confirmed that bark extracts have more active constituents compare to leaf extracts. by pharmacological evaluation of Ficus dalhousea Miq. Various extracts, most of them are capable of showing moderate antibacterial activity.

Understanding Cell Biology

The cell is the structural and functional unit of all living organisms and is sometimes called the "building block of life.” All living things are made from one or more cells. A cell is the simplest unit of life and they are responsible for keeping an organism alive and functioning. Almost every different type of cell contains genetic material, a membrane and cytoplasm. The most basic categorization of Earth’s organisms is determined by different types of cells. All cells can be divided into one of two classifications: prokaryotic cells and eukaryotic cells. Prokaryotic cells are found in bacteria and archaea. Eukaryotic cells are found in organisms from the domain Eukaryota which includes animals, plants, fungi and protists. Cell metabolism is the process by which individual cells process nutrient molecules. Metabolism has two distinct divisions: catabolism, in which the cell breaks down complex molecules to produce energy and reducing power, and anabolism, in which the cell uses energy and reducing power to construct complex molecules and perform other biological functions. Cells were discovered by Robert Hooke in 1665, who named them for their resemblance to cells inhabited by Christian monks in a monastery. Cell theory, first developed in 1839 by Matthias Jakob Schleiden and Theodor Schwann, states that all organisms are composed of one or more cells, that cells are the fundamental unit of structure and function in all living organisms, and that all cells come from pre-existing cells. Cells emerged on Earth at least 3.5 billion years ago. The study of cells is called cell biology or cellular biology.

Medicinal properties of Abutilon indicum

Abutilon indicum is a common Indian shrub, belonging to the family Malvaceae; Also known as Mallow in english, Abutilon indicum is used as a medicinal plant. It has been extensively used as a traditional medicine as a laxative, emollient, analgesic, anti-diabetic, anti-inflammatory and blood tonic agent and also in the treatment of leprosy, urinary disease, jaundice, piles, relieving thirst, cleaning wounds and ulcers, vaginal infections, diarrhea, rheumatism, mumps, pulmonary tuberculosis, bronchitis, allergy, blood dysentery, some nervous and some ear problems. Various studies on the plant extract have been performed to confirm the anti-oxidant, anti-bacterial, analgesic, anti-inflammatory, anti-cancer, hepato-protective, immuno-modulatory and larvicidal activities of the plant. This plant is often used as a medicinal plant and is considered invasive on certain tropical islands. In traditional medicine, A. indicum is used as a aphrodisiac, demulcent, diuretic, laxative, pulmonary and sedative (leaves). The bark is astringent and diuretic; laxative, expectorant and demulcent (seeds); laxative and tonic, anti-inflammatory and anthelmintic (plant); analgesic (fixed oil); diuretic and for leprosy (roots). The plant is very much used in Siddha medicines. In fact, the bark, root, leaves, flowers and seeds are all used for medicinal purposes by Tamils. The leaves are also used to treat for pile complaints. The flowers are traditionally used to increase semen in men. The phytochemical analysis showed the Presence of Alkaloid, Saponins, Amino acid, Flavonoids, Glycosides and steroids. This plant exhibits several potential pharmacological activities. A review on the various studies on the plant has been provided for the purpose of understanding its medicinal properties.

St John's wort (Hypericum perforatum L.): A Review of its Chemistry, Pharmacology and Clinical properties

St John's wort (also known as hypericum, millepertuis) is Hypericum perforatum L., Hypericaceae, an herbaceous perennial plant native to Europe and Asia, and which has been introduced into the United States where it has naturalized (38). The chemical composition of St. John's wort has been well-studied. Documented pharmacological activities, including antidepressant, antiviral, and antibacterial effects, provide supporting evidence for several of the traditional uses stated for St John's wort. Many pharmacological activities appear to be attributable to hypericin and to the flavanoid constituents; hypericin is also reported to be responsible for the photosensitive reactions that have been documented for St. John's wort. This systematic review overviews the literature on the use of St. John’s Wort for chemistry, pharmacology and clinical properties.
