ABSTRACT
Pseudomonas aeruginosa isolated from banana field rhizosphere produced different antifungal metabolites like bactriocin, hydrogen cyanide and siderophore. Bacteriocinogenic, siderophoregenic, and HCN rich broth of isolate inhibited the growth of phytopathogen like Aspergilus niger, Aspergilus flavus, Fusarium oxysporum and Alternaria alternata. The isolate exhibited more antifungal activity and comparatively low MIC vis-a-vis commonly used copper based systemic chemical fungicide;bil cop.

The principal pathways serving higher visual function comprise the dorsal stream and the ventral stream. The dorsal stream runs between the occipital lobes and the parietal lobes and subserves the ability to process the whole visual scene and carry out visually guided movement. The ventral stream runs between the occipital lobes and temporal lobe tissue and primarily subserves visual recognition and memory. These tissues are susceptible to dysfunction in children with brain damage. We report a series of 40 children in whom damage to the brain has led to a common symptom complex affecting vision. Lower visual field loss was frequently elicited. This was associated with impaired ability to make accurate visually guided movement (particularly of the lower limbs) accompanied by impaired simultaneous perception, and in some cases, with inaccurate saccades and in others, impaired perception of movement. These features are consistent with parietal/dorsal stream dysfunction. Difficulty recognising faces and problems with route finding (which are ventral stream functions) were also present in a number of the children. These visual difficulties can be manifest in the presence of normal visual acuity. Recognition of these problems leads to understanding of the child's visual difficulties and facilitates adaptation of curriculum delivery at school.

Sweat gland tumours are extremely rare in the eyelids. We report a case of a clear cell hidradenoma (nodular hidradenoma) in an elderly female, who had presented with a nodular swelling in a eyelid. Clear cell hidradenomas arise as intradermal nodules from eccrine sweat glands. Ultrastructural and enzyme histochemical studies have shown nodular hidradenomas to be intermediate between eccrine poroma and eccrine spiradenoma. No apocrine differentiation has ever been observed in these tumours. Malignant forms are distinctly unusual. This case is being documented for the extremely uncommon presentation of this tumour as an eyelid mass. Complete primary excision is advocated and local steroid preparations should bot be used.

82 female and 65 male, mostly unmarried undergraduate students read one of 16 versions of a brief scenario depicting a man or woman either engaging or not engaging in nurturant touching of young children. Subjects then rated story characters on masculinity and goodness scales and on scales measuring likelihood of social acceptance and future instrumental achievement. Men and women who engaged in nurturant touching were rated low on masculinity and high on goodness and social acceptance. Men rated male characters lowest on goodness and women rated male characters highest on goodness. Women who engaged in nurturant touching were given the highest goodness and social acceptance ratings. It was concluded that some men may avoid engaging in nurturant touching of young children due to gender stereotyping.
