Hypertension is a common problem facing many peoples today. Although billions of dollars are spent annually for the treatment and detection of cardiovascular disease, current conventional treatments have done little to reduce the number of patients with hypertension. Alternative medicine offers an effective way to decrease the rising number of people with high blood pressure. Research has found a variety of alternative therapies to be successful in reducing high blood pressure including diet, exercise, stress, management, supplements and herbs. Every year, more and more studies are being performed on herbal remedies for high blood pressure. There are many herbal drugslikePunarnava, Barberry, Rouwolfia, Garlic, Ginger, Ginseng and Arjuna which can safely use for the treatment of hypertension. This review highlight the herbs proved scientifically for the treatment of...

Tuberculosis is declared to be an infectious disease of global emergency by WHO. Approximately one-third of the world’s population is infected with the tuberculosis. The lengthy and laborious current treatment of 6-9 months is associated with problems like patient noncompliance, multiple drug resistance and persistence of mycobacterium and significant toxicity of drugs. The increasing emergence of drug resistance of mycobacterium highlights an urgent need to develop novel therapeutic targets and agents that are not only effective against drug resistant bacteria but can also herald the persistent form of bacteria and thereby shorten the length of TB treatment. However, an approach towards understanding the physiological characteristics of the mycobacterium and designing of such novel therapeutic agents that are effective against drug resistance & persistent bacteria can bring about a revolution in the TB chemotherapy in near...

A simple, sensitive and selective high performance liquid chromatography (HPLC) method with ultraviolet detection (220 nm) was developed and validated for the quantification of Ibuprofen and in human plasma. Following rapid sample preparation, the analytes and internal standard (Diclofenac sodium) were separated using an isocratic mobile phase on a reverse phase C8 column. The lower limit of quantification was 1µg/mL for Ibuprofen. A linear dynamic range of 1µg/mL to 100µg/mL for Ibuprofen was established. This HPLC method was validated with between and within-batch precision of 1.2- 4.7% and 1.8- 4.8 %, respectively. The between and within batch accuracy was 99.4- 104.2% and 99.7- 104.1%, respectively. Frequently co-administered drugs did not interfere with the described methodology. Stability of Ibuprofen in plasma was >90%, with no evidence of degradation during sample processing (autosampler) and 60 days storage in a freezer. This validated method is sensitive and simple with between-batch precision of < 5 % and was used in pharmacokinetic...

The different extracts of the roots of Bruguiera gymnorhiza (Family- Rhizophoraceae) were tested for anti-diabetic activity, by glucose tolerance test in normal rats and alloxan induced diabetic rats. Aqueous ethanol and butanol extracts had shown significant protection and lowered the blood glucose levels to normal in glucose tolerance test. In alloxan induced diabetic rats the maximum reduction in blood glucose was observed after 3h at a dose level of 250 mg/kg of body weight. The percentage protections by aqueous ethanol and butanol extracts were 30 and 48% respectively. In long term treatment of alloxan induced diabetic rats, the degree of protection was determined by measuring blood glucose, triglycerides, cholesterol and urea levels on 0,3,5,7 and 10th day. Both the extracts showed a significant anti- diabetic activity comparable with that of glibenclamide. The histopathological studies during the long-term treatment have shown to ameliorate the biochemical damages caused by alloxan. These results indicate that the B. gymnorhiza root possess significant anti -diabetic...

Inflammation is a biological reaction attributed with several acute and chronic pathological conditions. The study revealed the pharmacological effect of Tecomella undulate: bark against carrageenan induced paw edema and cotton pellet induced granuloma in rat. Wistar albino rats of either sex (180-240 g) were employed into the study. Acute inflammation was induced by injecting carrageenan (1%) in rat paw and estimated using plethysmograph. Chronic inflammation was induced by cotton pellet induced granuloma method. Serum nitrate/nitrate estimation was also done as an index of inflammatory reactions. Acute toxicity study was also done using Swiss albino mice. Butanolic and water fractions of Tecomella undulate (200 & 400 mg/kg) and indomethacin (10 mg/kg) were used as test drugs. Carrageennan caused a marked increase in rat paw volume due to edema formation. T. undulate: butanolic fraction significantly inhibited paw volume in successive hours similar to indomethacin. Interscapular implanted cotton caused significant increase in granuloma wt. and serum nitrate/nitrite level in control group. However, the test drugs lowered the effects of cotton pellet induced...
