Item An analysis of initial results of percutaneous transluminal coronary angioplasty for totally occluded coronary arteries.(1992-01-01) Shah, D C; Sathyamurthy, I; Samuel, M; Subramanian, K; Ramchandran, P; Lal, PA retrospective analysis of 680 Percutaneous Transluminal Coronary Angioplasties (PTCA) performed from April 1986 to October 1990 revealed that 81 patients had PTCA performed on 86 totally occluded coronary arteries (1.06 lesions/patient). Four of the 86 were acute occlusions. Angiographic success in the group as a whole was achieved in 57 (66%). Multivariate analysis identified only the target vessel as a statistically significant factor predictive of angiographic success from among a host of clinical and angiographic morphologic variables. Left anterior descending artery lesions were identified with the highest success. In addition the duration of occlusion was significantly lower for the successfully versus the unsuccessfully dilated chronic occlusions.Item Hypomelanosis of Ito.(2000-06-10) Samuel, M; Girimaji, S R; Christopher, R; Manjunatha,Item In vitro Anti-plasmodial Activity of Rubia cordifolia, Harrizonia abyssinica, Leucas calostachys Olive and Sanchus schweinfurthii Medicinal Plants.(2013-12) Nyambati, G K; Lagat, Z O; Maranga, R O; Samuel, M; Ozwara, HPlasmodium falciparum is becoming increasingly resistant to conventional antimalaria drugs. Rapid increase of parasite resistant strains, resistance of the vector to insecticides and the difficulty in creating efficient vaccines has lead to an urgent need for new anti-malarial drugs. To determine anti-plasmodial activity of Rubia cordifolia, Harrizonia abyssinica, Sachus schweinfurthii and Leucas calostachys Olive plants. Aqueous and methanolic crude extracts were prepared from R. cordifolia, H. abyssinica, S. schweinfurthii and L. calostachys plants. The extracts were then prepared into appropriate concentrations for anti-plasmodial activities. In vitro anti-plamsodial activities of herbal drugs were analysed according to the methods of Tona et al., 1999. Methanolic extracts were more efficacious than aqueous extracts. S. schweinfurthii and L. calostachys had IC50 (Inhibition Concentration) of between 1.10μg/ml and 3.45μg/ml and had highest parasite inhibition ranging between 3.5% and 5.2%. R. cardifolia and H. abyssinica had IC50 of between 1.5μg/ml and 3.0μg/ml and it had moderate parasitaemia ranging between 5.20% and 7.22%. Vernonia lasiopa and Erythrina abysinnica had insufficient yields. S. schweinfurthii and L. calostachys had the highest parasite inhibition while R. cardifolia and H. abyssinica had moderate inhibition.Item Salmonella tamilnadu (6,67:Z41:Z35) belonging to sub genus I: a new Salmonella serotype.(1970-01-01) Nath, M L; Singh, J; Bhandari, S K; Samuel, M; Koshi, G; Mammen, K C
