ABSTRACT
In Chaharborj, a village in north-eastern of the Islamic Republic of Iran, a high prevalence of congenital blindness [1.1%] has been reported. The clinical findings have not been fully described. We therefore assessed the clinical aspects of this condition in a case series of 20 congenially blind patients and 24 of their parents. All patients had been blind since birth. There was anterior segment dysgenesis and retinal non-attachment in all patients. There were no systemic anomalies. Histopathologically, there was iridocorneal adhesion, normal angle structure and retinal dysplasia. No significant difference was found in the frequency of different HLA class I alleles compared with the general population. The anomaly causing congenital blindness in these patients has components of both anterior and posterior segment dysgenesis. It appears to be a distinct entity with an autosomal recessive pattern of inheritance

Morphine is an opioid analgesic and has known effects on different organs. This study was done to determine the histopatological; changes of liver due to morphine administration in adult mice. In this experimental study, 20 male Blab/c mice divided experiment and control groups. In experiment and control group, animals received 15mg/kg/day morphine and salin normal interperitoneally, for 2days respectively. Day 22 the livers were dissected under anesthesiology. Specimens were processed for histological study and stanied with H and E. In experimental group, small sites of necrosis with poly morphic inflammatory infiltration and debris formation of necrotized nucleus in death area, so hepatitis was suggested. Also accumulation of micro droplets of lipid inside the hepatocyte cytoplasm withont nucleus displacement [fatty damages with small vacuoles] observed in cases. In addition, microvesicular steatosis and mouth teeth necrosis in liver parenchyma with inflammation in the vein and portal space were seen in cases. Any changes was not seen in control group. The interperitoneal administration of morphine can cause histopatological changes in mice liver
