The 11th edition of Harrison's Principles of Internal Medicine welcomes Anthony Fauci to its editorial staff, in addition to more than 85 new contributors. While the organization of the book is similar to previous editions, major emphasis has been placed on disorders that affect multiple organ systems. Important advances in genetics, immunology, and oncology are emphasized. Many chapters of the book have been rewritten and describe major advances in internal medicine. Subjects that received only a paragraph or two of attention in previous editions are now covered in entire chapters. Among the chapters that have been extensively revised are the chapters on infections in the compromised host, on skin rashes in infections, on many of the viral infections, including cytomegalovirus and Epstein-Barr virus, on sexually transmitted diseases, on diabetes mellitus, on disorders of bone and mineral metabolism, and on lymphadenopathy and splenomegaly. The major revisions in these chapters and many

Some phytochemical, pharmacological and toxicological properties of ginger (Zingiber officinale Roscoe): a review of recent research.

To evaluate the antibacterial activity of 21 plant essential oils against six bacterial species. The selected essential oils were screened against four gram-negative bacteria (Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Proteus vulgaris) and two gram-positive bacteria Bacillus subtilis and Staphylococcus aureus at four different concentrations (1:1, 1:5, 1:10 and 1:20) using disc diffusion method. The MIC of the active essential oils were tested using two fold agar dilution method at concentrations ranging from 0.2 to 25.6 mg/ml. Out of 21 essential oils tested, 19 oils showed antibacterial activity against one or more strains. Cinnamon, clove, geranium, lemon, lime, orange and rosemary oils exhibited significant inhibitory effect. Cinnamon oil showed promising inhibitory activity even at low concentration, whereas aniseed, eucalyptus and camphor oils were least active against the tested bacteria. In general, B. subtilis was the most susceptible. On the other hand, K. pneumoniae exhibited low degree of sensitivity. Majority of the oils showed antibacterial activity against the tested strains. However Cinnamon, clove and lime oils were found to be inhibiting both gram-positive and gram-negative bacteria. Cinnamon oil can be a good source of antibacterial agents.

Objective: Berberis aristata (Berberidaceae) is an important medicinal plant used in traditional system of medicine for the treatment of rheumatoid arthritis and other inflammatory disorders. The aim of the present study is to scientifically validate the traditional use of BA in the treatment of inflammatory disorders. Materials and Methods: Anti-inflammatory and anti-granuloma activity of BA hydroalcoholic extract (BAHE) were evaluated in experimental models, viz., carrageenan-induced paw edema, cotton pellet-induced granuloma formation, and complete Freund's adjuvant-induced stimulation of peritoneal macrophages in rats. Expression of inflammatory mediators, viz., tumor necrosis factor-alpha (TNF-α), interleukin-1β (IL-1β), IL-6, IL-10, TNF-R1, and cyclooxygenase-2 (COX-2) was carried out in serum and peritoneal macrophages to derive the plausible mechanism of BAHE in activated peritoneal macrophages. Results: Pretreatment with BAHE produced a dose-dependent reduction (P Conclusion: The result of the present study thus demonstrates the anti-inflammatory and anti-granuloma activity of BAHE which may be attributed to its inhibitory activity on macrophage-derived cytokine and mediators.

Background Cinnamomum cassia iswidely used as a traditional medicinal plant for the treatment of rheumatoid arthritis. Objective The present study aimed to assess the anti-arthritic activity of C. cassia bark hydroalcoholic extract (CCHE) in different arthritic animal models. Methods In formaldehyde model, sub-plantar administration of 0.1 ml of formaldehyde (2% v/v) into the right hind paws of Wistar albino rats on days 0 and 3. The rats were divided into six groups as follows: normal control, disease control, indomethacin group (3 mg/kg, p.o.) and three groups, treated with 50, 100 and 200 mg/kg CCHE (p.o.). Joint diameter was measured, and ankle joints were collected for MDA and GSH measurements. In complete Freund's adjuvant (CFA)-induced arthritis model, CFA was injected into the sub-plantar surface of the right hind paw in rats. Joint diameter was measured, and serum TNF-α and IL-1β were measured. Histopathological and immunohistochemical analyses were also performed. Results CCHE treatment significantly (p  Conclusion Based on these findings, it can be concluded that C. cassia possesses anti-arthritic properties.

Genus Plumeria (Apocynaceae) contain largely of shrubs or flowering trees which are grown throughout the tropical region including many parts of India. These plants are well known for their religious value, cosmetic importance and tremendous potential to be used as medicinal agents to cure infections, digestive diseases, anti-inflammatory and antipyretic action, anti-tumor potential, anti-oxidant properties etc. In this review article various established facts regarding species of Plumeria have been compiled. The article highlights the historical findingsand present medicinal status of these plants with their potential to be used in the field of drug development in future.

Protective effects of Glycyrrhiza glabra supplementation against methotrexate-induced hepato-renal damage in rats: An experimental approach.

Incisive search of innovative compounds for regulating pain, inflammation, and bone damage, with nominal side effects has focused on nutritional supplements. The endeavor of this research work was to investigate, for first time, the inhibitory effect of pomegranate rind extract in established models of nociception and inflammation. Pomegranate (50, 100, and 200 mg/kg) and indomethacin (3 mg/kg) was assessed in eddy's hot plate-induced algesia, carrageenan, and Complete Freund's adjuvant-induced models in Wistar rats. Results of study conclude that pomegranate at a dose of 200 mg/kg showed significant (p < 0.001) reduction in paw swelling in both inflammatory experimental models. In addition, observations recorded a significant (p < 0.05) increase in nociceptive threshold. Henceforth, we might say that pomegranate (200 mg/kg) decline pain and inflammation by downregulating the activation of TNF-R1, TNF-α, IL-1β, IL-6, NF-κB, oxidative stress markers, and tissue histology. PRACTICAL APPLICATIONS: The research work represents the first report on inhibitory mechanism of NF-κB by pomegranate rind extract, enriched in tannins and flavanoids. The findings of the study provide satisfactory evidence of pomegranate rind in amelioration of adjuvant-induced arthritis. Pomegranate rind, being enrich in bioactive compounds like phenolics and flavanoids possess potent antioxidant activity that might contribute in attenuating rheumatoid arthritis.
