Miliary tuberculosis (TB) is a potentially lethal disease if not diagnosed and treated early. Diagnosing miliary TB can be a challenge that can perplex even the most experienced clinicians. Clinical manifestations are nonspecific, typical chest radiograph findings may not be evident till late in the disease, high resolution computed tomography (HRCT) shows randomly distributed miliary nodules and is relatively more sensitive. ⋯ A high index of clinical suspicion and early diagnosis and timely institution of anti-tuberculosis treatment can be life-saving. Response to first-line anti-tuberculosis drugs is good but drug-induced hepatotoxicity and drug-drug interactions in human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) patients pose significant problems during treatment. However, sparse data are available from randomized controlled trials to define the optimum regimen and duration of treatment in patients with drug-sensitive as well as drug-resistant miliary TB, including those with HIV/AIDS.

A large number of plants have been recognized to be effective in the treatment of diabetes mellitus. Persistent hyperglycaemia is associated with decreased function of immune system and cerebral ischaemia mainly due to increased oxidative stress and inflammatory response. Andrographis paniculata is a medicinal plant widely used in folk medicine for various purposes. In this study the effect of chronic administration (7 days) of methanolic extract of A. paniculata leaves was studied in rats with experimentally induced diabetes, nootropic and immunostimulant activities were evaluated. The effect of acute administration of methanolic extract of A. paniculata leaves was also studied for cerebroprotective activity. ⋯ The antioxidant activity of the methanolic extract of A. paniculata leaves was evident by decreased tissue malondialdehyde (MDA) levels and increased SOD levels. These properties may be responsible for the observed cerebroprotective activity. The methanolic leaf extract of A. paniculata showed significant immunostimulant, cerebroprotective and nootropic activities in normal and type 2 diabetic rats.
