Striped bass Morone saxatilis were infected intraperitoneally with approximately 10(5) Mycobacterium marinum, M. shottsii sp. nov., or M. gordonae. Infected fish were maintained in a flow-through freshwater system at 18 to 21 degrees C, and were examined histologically and bacteriologically at 2, 4, 6, 8, 17, 26, 36 and 45 wk post-infection (p.i.). M. marinum caused acute peritonitis, followed ...

Simple 7,2',4'-oxygenated isoflavans accumulate in the fungus-inoculated tissues of many papilionate legumes where they appear to function as defensive compounds (phytoalexins) [1, 2], Vestitol (7,2'-dihydroxy-4'-methoxyisoflavan, 1) is the most common isoflavan phytoalexin [3] and occurs widely in the Papilionoideae subfamily of the Leguminosae; in contrast, the related compound, isovestitol (...

Although the heartwood of Dalbergia odorifera T. Chen (Leguminosae) is an important source of traditional Korean and Chinese medicines, the effects of novel compound methoxydalbergione (4-MD) isolated from Dalbergia odorifera was not reported. Herein, we investigated the effects of the 4-MD in vitro and in vivo against osteosarcoma cells and its molecular mechanisms. 4-MD inhibited the prolifer...

The benzene, alcoholic and aqueous root extracts (75mg/kg each)of Dalbergia spinosa Roxb were studied for its diuretic activity by using male albino rats by adopting the method of Tipschitz. The alcoholic extract increased the urine volume and electrolytes sodium, potassium and chloride, which is similar to the standard drug Furosemide (100mg/ kg) by inhibiting sodium, potassium, and chloride i...

Leptotrombidium subqunadratum larvae were collected for the first time in 1994 from dogs in Bloemfontein. The larvae have been collected annually, during the summer months, over a period of 6-7 years. Previously the only known hosts were scrub hare (Lepus saxatilis) (locality unknown) and short-snouted elephant shrew (Elephantulus brachyrhynchus) (Kruger National Park). These mites cause severe...

A plantation trial of six selected clones of Dalbergia sissoo Roxb. laid out in randomized block design at four sites in northern India during July, 1996 was evaluated for growth, physiological and biochemical parameters. Genotype-site interactions were significant for collar diameter increment, photosynthetic rate, transpiration rate, stomatal conductance, photosynthetic pigments, total solubl...
