This report describes a retrospective study of all new patients in our uveitis clinic between January 1992 and December 1994, undertaken to identify the pattern of uveitis in the Indian subcontinent. A standard clinical protocol, and the naming-meshing system with tailored laboratory investigations were used to arrive at a final uveitic diagnosis. Uveitis comprised 1.5% of new cases seen at the centre. Out of 1273 uveitis cases, anterior uveitis was the most common type (39.28%), followed by posterior uveitis (28.75%), intermediate uveitis (17.44%), and panuveitis (14.53 %). The most commonly affected age group were patients in their forties (23.57%). Uveitis was less common in children below 10 years (3.61%) and in adults over 60 years of age (6.44%). Men (62.21%) were more commonly affected than women (37.79%). Aetiology remained undetermined in 59.31% of cases. Anterior uveitis was most commonly idiopathic (58.6%). The most common cause of posterior uveitis was toxoplasmosis (27.87%), and that of panuveitis was the Vogt-Koyanagi-Harada syndrome (21.08%). A higher incidence of microbiologically proven tubercular uveitis (5 cases), and uveitis due to live intraocular nematode (4 cases), and malaria (1 case), were seen, in contrast to other studies. Only 2 cases of AIDS with ocular lesions were seen. This paper reveals the pattern of uveitis seen at a major referral eye institute in India.

Antioxidant and antifibrotic properties of colchicine were investigated in the carbon tetrachloride (CCl(4)) rat model. (1) The protective effect of colchicine pretreatment on CCl(4) induced oxidant stress was examined in rats subsequently receiving a single lethal dose of CCl(4). Urinary 8-isoprostane, kidney and liver malondialdehyde and kidney glutathione levels increased following CCl(4) treatment, but only the rise in kidney malondialdehyde was significantly inhibited by colchicine pretreatment. Serum total antioxidant levels were significantly higher in the colchicine pretreatment group. (2) The long term effects of colchicine treatment on CCl(4) induced liver damage were investigated using liver histology and biochemical markers (hydroxyproline and type III procollagen peptide). Co-administration of colchicine with sub-lethal doses of CCl(4) over 10 weeks did not prevent progression to cirrhosis. However, rats made cirrhotic with repeated CCl(4) challenge and subsequently treated with colchicine for 12 months, all showed histological regression of cirrhosis. (3) The antioxidant effect of colchicine in vitro was evident only at very high concentrations compared to other plasma antioxidants. In summary, colchicine has only weak antioxidant properties, but does afford some protection against oxidative stress; more importantly, long term treatment with this drug may be of value in producing regression of established cirrhosis.

Sarcoidosis is a relatively common, chronic, multisystem disease of unknown origin. It most commonly affects young adults and usually manifests with bilateral hilar lymphadenopathy or pulmonary infiltrates. Alternatively, it may present with protean manifestations. It has been documented in all organs of the body, with the exception of the adrenal gland. We describe a male patient who presented with hepatic sarcoidosis, with a sclerosing cholangitis-like picture, but without any pulmonary involvement. He was treated with prednisolone and cyclophosphamide, the latter as a steroid-sparing agent. A few years later, renal adenocarcinoma developed. We postulate that this could be related to cyclophosphamide treatment. We present this case history for two reasons: (1) sarcoidosis, selectively affecting the liver and lymph nodes but not the lung, with its hepatic involvement mimicking sclerosing cholangitis, has not previously been reported: and (2) although long-term cyclophosphamide treatment is known to be associated with malignancy, there is only one previous report of its association with a renal adenocarcinoma.

End stage glomerulosclerosis is associated with hypocellular glomeruli almost entirely replaced by abnormal matrix proteins. As apoptosis has an established role in the determination of cellularity in a wide range of physiological situations including resolution of experimental self limited mesangial proliferative nephritis, and as matrix proteins secreted by mesangial cells are altered in chronic diseases, we have studied the effects of different matrix proteins on mesangial cell apoptosis in vifro.Apoptosis was induced by 8 hours serum starvation and quantified by fluorescent microscopical counts of rat mesangial cell cultures. If cells were subcultured directly onto tissue culture plastic, 27.0 f 6.1% underwent apoptosis after serum starvation. However if the wells were
