Immunomodulating agents of plant origin. I: Preliminary screening.

The immunobiological activity was investigated of certain medicinal plants widely used in the Ayurvedic and Unani systems of medicine for treatment of chronic infections and immunological disorders. The effect of an ethanolic extract of each drug was studied on delayed type hypersensitivity, humoral responses to sheep red blood cells, skin allograft rejection, and phagocytic activity of the reticuloendothelial system in mice. Picrorhiza kurroa was found to be a potent immunostimulant, stimulating both cell-mediated and humoral immunity. Tylophora indica, Aconitum heterophyllum and Holarrhena antidysenterica appeared to stimulate phagocytic function while inhibiting the humoral component of the immune system. Tinospora cordifolia and Ocimum gratissimum appeared to improve the phagocytic function without affecting the humoral or cell-mediated immune system. Hemidesmus indicus suppressed both the cell-mediated and humoral components of the immune system.

Oral zinc as an adjunct to dapsone in lepromatous leprosy.

Oral zinc was tried in 15 cases of multibacillary leprosy as an immunostimulant in addition to conventional antileprosy drugs. Results were compared with those in ten similar cases treated with dapsone alone. Cases treated with zinc showed faster clinical improvement, regrowth of eyebrows, rapid fall in the bacterial index (BI) and in the bacterial index in the granuloma (BIG), early and greater influx in lymphocytes in the granuloma, and neovascularization. Upgrading occurred in 6 out of 15 patients taking zinc, but in only 1 out of 10 patients in the control group. Five out of six patients who showed upgrading in the treated group became lepromin positive. Only one patient (BL) showed lepromin conversion in the control group.

Haematological and biochemical characteristics of Heteropneustes fossilis under the stress of Congo Red (diphenyl disazo binaphthionic acid).

The effects of the sublethal concentration (0.012%) of Congo Red on Heteropneustes fossilis were studied after 30 days exposure. The RBC count haemoglobin (Hb)% and PCV decreased significantly. The total WBC count, MCV, MCH, and MCHC showed a significant increase. Serum calcium, serum cholesterol and blood urea nitrogen (BUN) were significantly elevated, whereas serum phosphorus was significantly reduced. The activities of serum alkaline phosphatase (AlPase), acid phosphatase (AcPase). RNase, GOT, GPT and amylase were also significantly elevated. The possible reasons for these changes are discussed.
