Abstract
Nine polyps retrieved from the upper gastrointestinal tract by endoscopic polypectomy in nine patients are reported. Polyps were removed from the distal esophagus (1), stomach (7) and duodenum (1). Dysphagia, obstructive jaundice and upper gastrointestinal bleeding were the presenting features in four patients. In five patients gastric polyps were detected incidentally at endoscopy. Of the nine polyps, six were adenomas, two were hyperplastic polyps and one in the esophagus was inflammatory. All the polyps could be retrieved completely and there were no complications. Thus polyps do occur in the upper gastrointestinal tract in India; their electrosurgical removal is easy and safe and allows histopathological examination of the entire polyp.

Abstract
The main PERG component of the transient contrast reversal pattern electroretinogram (PERG) in cats was a negative wave (3.5 microV average, SD 1.7 microV) peaking at about 130 msec (N130) with a spatial resolution above 5.5 c/deg, close to behavioural estimates. The early positivity (P35) was more variable, smaller and had lower spatial resolution. Different anaesthetic protocols affected both the waveform and the amplitude by spatial frequency functions. Responses of urethane anaesthetised cats were like those reported previously for decerebrate cats or cats paralysed and ventilated with N2O/O2/CO2 (75%/24%/1%). P35 was evoked only by coarse stimuli and N130 amplitude decreased linearly as spatial frequency increased. When the luminance response amplitude, predicted from the optical transfer function of the eye, was subtracted, spatial tuning appeared. An anaesthetic mixture of ketamine hydrochloride and xylazine depressed both P35 and N130 at low spatial frequencies while enhancing them at high frequencies. In paralysed animals ventilated with N2O/O2 (67%/33%) P35 was larger and recordable to 1.6 c/deg. Peak times were reduced and the inter-peak time halved. Other anaesthetics depressed the ERGs. These effects suggest that cats are a good model for studying N130 in isolation or its interaction with P35 and that both PERG peaks include luminance and pattern components.

Abstract
Cats are very sensitive to induction of anaesthesia by urethane. To anaesthetize cats with urethane, 1.0-1.3 g/kg, of freshly prepared urethane is administered intravenously at a rate of 1.92 g/h, while anaesthesia is maintained with 0.5% halothane in a 66%/33% nitrous oxide/carbogen gas mixture. Cats can then be maintained for up to 3 days by intravenous infusion at a rate of 4 ml/h of a 100 ml solution containing 50 IU heparin, 2.4 mg atropine, 4.7 g anhydrous D-glucose, and 240 mg urethane/kg. Using this anaesthetic, excellent electroretinograms can be recorded with no interfering eye movements.

Abstract
Between 1982 and 1987, 43 patients with variceal bleeding due to extrahepatic portal obstruction were treated by repeated endoscopic injection sclerotherapy using 1% polidocanol intravariceally. This decreased rebleeding, as evidenced by a decrease in bleeding risk factor (BRF), mean transfusion requirement, and mean number of transfusions per patient per month of follow-up. Differences between pre- and postsclerotherapy parameters were significant (p less than 0.001). The varices were eradicated in 86% of patients. The mean sclerotherapy sessions required were 7.68 +/- 2.39 (SD). Complications were infrequent. Forty-three patients were followed from 5 to 68 months: cumulative survival was 97.7% and varices recurred in 16%. Sclerotherapy avoided a second operation in 21 postsurgical patients. Sclerotherapy for managing variceal bleeding due to extrahepatic portal obstruction is a reasonable alternative to surgery.

Abstract
The recent regognition of AIDS has stimulated the development of newer cytotoxic therapies and hematological support system which have prolonged the life of these immunocompromised subjects. Moreover, greater number of patients are being recognised who are susceptible to various opportunistic infections involving the GI tract. In view of the poor anti-inflammatory response and minimal signs and symptoms of infection, the diagnosis of these organisms is often difficult. Hence a proper knowledge of the predisposing conditions and meticulous attention to minor symptoms and thorough physical examination alone can lead to an early diagnosis of infection. The common infectious agents include cryptosporiodium, herps virus cytomegalovirus and Giardia. Since, a satisfactory treatment is not available for many of these pathogens, attention should be paid to preventive measures while injudicious use of broadspectrum antibiotics must be checked to prevent superinfections.

Abstract
This reports a 27 yr old female Patient with seronegative polyarthritis who presented with lower GI bleeding and subsequently developed evidence of cutaneous vasculitis (palpable purpura) and orogenital ulcers. The cause of the GI bleeding was multiple ulcerations in the terminal ileum, cecum ascending colon and transverse colon. Continued and massive bleeding necessitated surgical resection of the involved segment of gut which on histopathological examination confirmed the presence of vasculities. This patient was thus diagnosed as having Behcet's disease. Although major GI bleeding is a rare manifestation of Behcet's disease with vasculitis of the gut, one must consider this possibility if the patient has multi-system involvement with evidence of vasculitis involving the skin in the form of palpable purpura.

Abstract
In the treatment of congenital or acquired subluxation of the lens a conservative approach to reposition the pupil in front of the aphakic area by the use of the xenon arc photocoagulator is emphasised. The management of two cases of subluxation is discussed in detail and the results evaluated. The ease of repositioning the pupil by means of iris photocoagulation and the absence of surgical complications are indications for the use of this non-invasive procedure in the treatment of subluxated lenses.
