Pharmacokinetics of rosuvastatin/olmesartan fixed-dose combination: a single-dose, randomized, open-label, 2-period crossover study in healthy Korean subjects.


Contamination of ground water by arsenic has become a cause of global public health concern. In West Bengal, India, almost 6 million people are endemically exposed to inorganic arsenic by drinking heavily contaminated groundwater through hand-pumped tube wells. No safe, effective and specific preventive or therapeutic measures for treating arsenic poisoning are available. We recently reported that some of the herbal extracts possess properties effective in reducing arsenic concentration and in restoring some of the toxic effects of arsenic in animal models. Moringa oleifera Lamarack (English: Horseradish-tree, Drumstick-tree, Hindi: Saijan, Sanskrit: Shigru) belongs to the Moringaceae family, is generally known in the developing world as a vegetable, a medicinal plant and a source of vegetable oil. The objective of the present study was to determine whether Moringa oleifera (M. oleifera) seed powder could restore arsenic induced oxidative stress and reduce body arsenic burden. Exposure to arsenic (2.5 mg/kg, intraperitoneally for 6weeks) led to a significant increase in the levels of tissue reactive oxygen species (ROS), metallothionein (MT) and thiobarbituric acid reactive substance (TBARS) which were accompanied by a decrease in the activities in the antioxidant enzymes such as superoxide dismutase (SOD), catalase and glutathione peroxidase (GPx) in mice. Arsenic exposed mice also exhibited liver injury as reflected by reduced acid phosphatase (ACP), alkaline phosphatase (ALP) and aspartate aminotransferase (AST) activities and altered heme synthesis pathway as shown by inhibited blood delta-aminolevulinic acid dehydratase (delta-ALAD) activity. Co-administration of M. oleifera seed powder (250 and 500 mg/kg, orally) with arsenic significantly increased the activities of SOD, catalase, GPx with elevation in reduced GSH level in tissues (liver, kidney and brain). These changes were accompanied by approximately 57%, 64% and 17% decrease in blood ROS, liver metallothionein (MT) and lipid peroxidation respectively in animal co-administered with M. oleifera and arsenic. Another interesting observation has been the reduced uptake of arsenic in soft tissues (55% in blood, 65% in liver, 54% in kidneys and 34% in brain) following administration of M. oleifera seed powder (particularly at the dose of 500 mg/kg). It can thus be concluded from the present study that concomitant administration of M. oleifera seed powder with arsenic could significantly protect animals from oxidative stress and in reducing tissue arsenic concentration. Administration of M. oleifera seed powder thus could also be beneficial during chelation therapy with a thiol chelator.

Objective. Urinary tract infections (UTI) are the most common problem in clinical practice. Usually they are asymptomatic and are commonly present with distressing symptoms like pain and burning sensation on urination. Antibiotics are widely used to treat UTIs; however, they have their own limitations like resistance, reinfection, and relapses. The purpose of the current study was to evaluate the value of Moringa oleifera Lam. stem bark as a potential medicine for UTIs. Study Design. 30 patients with UTI were randomly divided into two groups with 15 patients in each group. Shigru bark was given to patients of the first group (trial group) and modern medicines were prescribed to the other group of patients. At least three follow-ups are taken in both groups at the end of every week of treatment. Results. After treatment 66.67 % were cured, 13.33 % improved, 13.33% patients have no change, and 6.67% relapsed in trial group and in control group 46.67% were cured, 26.66% improved, 6.67% patients have no change, and 20% relapsed. Interpretation and Conclusion. The trial drug is significant in the management of UTI. This study needs to be done on a large scale and for a long time.

Uterine enlargement is common in reproductive life of a female. Other than pregnancy, it is seen most frequently in the result of leiomyomas. Leiomyomas, are benign smooth muscle neoplasmas that typically originate from the myometrium, due to fibrous consistency and are also called as fibroid. They may be identified in asymptomatic women during routine pelvic examination or may cause symptoms. Typical complaints include pain, pressure sensations, dysmenorrhea or abnormal uterine bleeding. Management of uterine fibroid through surgery is available to meet urgent need of the patient, but challenges remain to establish a satisfactory conservatory medical treatment till date. Hence, it was critically reviewed in the context of Granthi Roga (disease) and treatment protocol befitting the Samprapti Vighatana of Granthi (encapsulated growth) was subjected in patients of uterine fibroids. Seven cases of uterine fibroid were managed by Ayurvedic intervention. Ultrasonography (USG) of the lower abdomen was the main investigative/diagnostic tool in this study. After 7 weeks, patients presented with USG report as absence of uterine fibroid. Ayurvedic formulations Kanchanara Guggulu, Shigru Guggulu, and Haridra Khand are found to be effective treatment modality in uterine fibroid.
