Alpha and beta naphthols, the metabolites of naphthalene, a cataractogenic agent, was tested for it's effect on sheep lens proteases and their inhibitors. It reduced protease activities, not that of inhibitor activities of lens proteins. It also increased the efflux of free amino acid from lenses which was retarded by a high concentration of tissue galactose.

Humoral immune reactions as reflected in sera and cerebrospinal fluid (CSF) of 50 patients with Tuberculous meningitis (TBM) were studied. CSFs and sera from 50 patients with nontuberculous neurological diseases were selected as controls. CSFs of patients with TBM showed high titres of circulating antimycobacterial antibodies than in nontuberculous subjects. The CSF-IgG index is significantly higher in patients with TBM. Humoral immune reaction could be applied in the laboratory diagnosis of TBM, particularly when repeated bacteriological methods are negative for M. tuberculosis in CSFs.

Transplantation of reproductive organs have been unsuccessful to date because transplantation models utilised have never taken into consideration the vascular models of the reproductive system especially that of the female. This article examines the future of large organ transplantation in reproductive system and also the transplantation of cellular and tissue components as in embryo transfers. It also examines the future of such research procedures as embryo splicing, nuclear gene injections and transplantation in reproductive technologies.
