Basakarista (BSK), a well-known ayurvedic preparation, is widely used as a traditional medicine in the treatment of cough and respiratory trouble. In this study, effect of BSK on organ toxicity profile was evaluated after chronic administration of this drug to female Sprague-Dawley rats. The acute pharmacological study of BSK recorded no death or any signs of toxicity even at the highest dose of 80 ml/Kg body weight. For chronic pharmacological evaluation, the animals were divided into two groups. The first group was given BSK preparation at a dose of 40 ml/kg body weight for 35 days while the second group that served as the control received water for the same period. All throughout the experimental period, the BSK treated animals were always maintaining negligible decrease in body weight, in the body weight study, but it was not significant. There is a statistically significant (p=0.05) decrease in the absolute and relative weight of rat heart, kidney, spleen and thymus. The drug (BSK) also significantly decrease the tissue hydration index in heart and lung. These results demonstrate that BSK should not be administered chronically at a higher dose.

Naradiya Laksmivilasa Rasa (NMB) is a classical Ayurvedic formulation, indicated for the treatment of sinusitis, chronic skin diseases, diabetes, obesity, rheumatoid arthritis, headache, gynaecological disorders and urinary tract infections. However, till date, no safety profile of this formulation has been reported. That is why, the present study was conducted to evaluate the effect of conventionally prepared NMB on different kidney profile parameters in experimental animals. Acute toxicity study was conducted to determine the median lethal dose (LD50) of the drug. The LD50 study of NMB recorded no death or any signs of toxicity even at the highest dose of 4000 mg/Kg body weight. To find out the effect of chronic administration of NMB on serum kidney profile, it was administered chronically to the male Sprague-Dawley rats at a dose of 400 mg/kg for 43 days. Naradiya Laksmivilasa Rasa significantly decreased albumin and A/G ratio and significantly increased globulin, urea and Blood Urea Nitrogen (BUN) level. BUN/Creatinine and Urea/Creatinine level were significantly increased in NMB treated rats when compared to normal control. The drug (NMB) did not affect total protein and creatinine level significantly. This experimental data will help the clinician for the logical use of NMB in different disease conditions.

 Abstract                  View                 Download                 XML

Naproxen-Soluplus Nanoformulations (NFs) prepared via wet milling, using a conventional Retsch Planetary ball mill have been studied for their phase solubility behavior, physico-chemical characteristics, cytotoxicity, and morphology and dissolution enhancement. The highest dissolution enhancement of 172% over that of pure the drug was achieved for the formulation with Naproxen-Soluplus® ratio of 1:4. The ability of amphiphillic surfactant carriers to accelerate in vitro dissolution of poorly water-soluble drugs has been attributed to wetting, miceller solubilization, and/or deflocculation. The Korsemeyer–Peppas model most aptly fits the in vitro dissolution data and gives an insight into the possible drug release mechanisms predominated by anomalous non-Fickian diffusion which improves the physicochemical characteristics of naproxen towards its dissolution enhancement and the increase in the oral bioavailability of the drug without any adverse cytotoxic consequences.

Hermansky-Pudlak disorder (HPS) is a multisystem disease that is acquired in an autosomal latent way and is portrayed by tyrosinase-positive oculocutaneous. Hermansky-Pudlak disorder (HPS), the most penetrant of the hereditary pneumonic fibrosis disorders, gives a convincing criterion to concentrate the cell pathogenesis of aspiratory fibrosis. At present, OMIM (On line Mendelian Inheritance of Man) portrays 10 hereditary subtypes of HPS: sort 1 (because of changes in HPS1), sort 2 (AP3B1), sort 3 (HPS3), sort 4 (HPS4), sort 5 (HPS5), sort 6 (HPS6), sort 7 (DTNBP1), sort 8 (BLOC1S3), sort 9 (BLOC1S6), and sort 10 (AP3D1) product of 8 of the 10 HPS genes. Hermansky-Pudlak disorder platelets and wild-sort (WT) endothelial cells. Typically, platelets contain two sorts of granules as alpha and delta granules. The diagnosis of Hermansky-Pudlak disorder (HPS) is set up by clinical disclosure of oculocutaneous albinism in blend with a draining diathesis of variable seriousness. There is no compelling treatment for aspiratory fibrosis because of HPS, Desmopressin can be utilized as prophylactic treatment.
